Additional attributes to 5th generation (5G) neighbor cell relationships can be incorporated into a neighbor cell relationship table (NCRT). Messages between centralized units can support a hierarchical neighbor relation structure in a virtualized 5G radio access network (RAN). The additional attributes can improve the efficiency of 5G neighbor relation management via intra-centralized unit, inter-centralized unit, inter-radio access technology, and intra-radio access technology mobility management. 5G new radio (NR) long-term evolution (LTE) dual connectivity performance can also be improved by enabling the dual connectivity in the best suitable 5G NR cell.
To increase network efficiency, a user equipment (UE) can be appointed as a local manager to coordinate the allocation of resources used by other UEs. For example, the network can promote the UE as a local manager and assign the local manager a resource pool. The local manager can then broadcast synchronization signals to let the other UEs associate themselves with the local manager. After the other UEs are synced with the local manager, the local manager can allocate resources to the other UEs. Based on report data regarding the local managers management procedures, the network can maintain the UE as the local manager or demote the UE from local manager status.

Compression techniques can reduce the fronthaul throughput in split radio access network (RAN) architectures for next generation designs. Adaptive fixed-point mapping can reduce the throughput requirements between a baseband unit (DU) and a remote radio unit (RU). Thus, a bit or plurality of bits can indicate the type of data being passed over the fronthaul. Consequently, adaptive mapping between precoded downlink data and non-precoded downlink data suited to the type of data passed over the fronthaul can achieve high compression ratios.
BACKHAULING OF TRAFFIC FROM 3GPP AND NON-3GPP BASED RADIO ACCESS TECHNOLOGIES VIA NEW RADIO INTEGRATED ACCESS BACKHAUL FOR 5G OR OTHER NEXT GENERATION NETWORK
Various embodiments disclosed herein provide for the provisioning of backhaul links over a 5G NR (New Radio) integrated access and backhaul (IAB) network for access nodes using non-5G radio access technologies. In this way, the IAB network can service devices that are connected to the core network via older 3GPP technologies, or even non-3GPP technologies such as Wi-Fi. An IAB mobile terminal can be provided at the end point access node to make the access node an IAB node. Using an existing internet protocol (IP) routing in the IAB network, or providing for an IP tunnel between the endpoint access node and the core network can then facilitate providing backhaul services for the non-5G access node.

MAPPING REFERENCE SIGNALS IN WIRELESS COMMUNICATION SYSTEMS TO AVOID REPETITION
The described technology is generally directed towards having a transmitter in a wireless network generate and map reference signal sequences (e.g., for demodulation or other reference signal usage) so that the reference signal sequences are non-repetitive in a resource block. Avoiding repetition of the reference signal sequences reduces the peak-to-average power ratio in orthogonal frequency-division multiplexing (OFDM) systems. In one aspect, a transmitter device generates different reference signal sequences to avoid repetition of resource signal sequences, and maps the different reference signal sequences to appropriate (different) resource elements of a resource block. In one implementation, the different reference signal sequences can be based on different indexes of antenna ports. In an alternative implementation, the different reference signal sequences can be based on different code division multiplexing groups.
Facilitating frame structure coordination in wireless communication systems with integrated access and backhaul links in advanced networks (e.g., 4G, 5G, and beyond) is provided herein. Operations of a system can comprise facilitating a first configuration of a first group of flexible symbols and facilitating a second configuration of a first pattern defined for an uplink transmission. Further, the operations can comprise facilitating a third configuration of a second pattern defined for a downlink transmission and facilitating a fourth configuration of a second group of flexible symbols. Flexible symbols can be symbols within a slot that are not defined as uplink symbols or downlink symbols.
Facilitating improved performance in advanced networks (e.g., 4G, 5G, and beyond) with multiple transmission points is provided herein. Operations of a system can comprise determining respective port numbers for respective ranks of a first transmission to a user equipment device. The operations also can comprise receiving an indication, from a second network device, of a first demodulation reference signal associated with a port number for a rank of a second transmission to the user equipment device from the second network device. Further, the operations can comprise facilitating a conveyance of the first transmission to the user equipment device. The first transmission can comprise a second demodulation reference signal on a different port number than the port number associated with the second transmission.
Because the number of transmitted layers can vary dynamically, the number of transmitted demodulation reference signals (DM-RS) can also vary. However, because the network node can know the number of ports, transmitted layers, or the rank, the network node can utilize the number as part of the scheduling information via a downlink or an uplink control channel. Therefore, the DMRS sequence generation can modified such that it depends on the number of ports, transmitted layers, or the rank, thereby generating a different random sequence for different ports.
Facilitating channel state information determination using demodulation reference signals in advanced networks (e.g., 4G, 5G, and beyond) is provided herein. Operations of a system can comprise communicating first channel state information to a network device of a communication network. The first channel state information can be determined based on a received reference signal. The operations can also comprise determining second channel state information based on a scheduled demodulation reference signal received from the network device and comprising determining a precoding matrix index, rank information, and channel quality index information. Further, the operations can comprise communicating the second channel state information to the network device.
The same or similar physical signals can be used for both user equipment (UE) and an integrate access backhaul (IAB) node. Different configurations of the resources and/or transmission periods of the signals can be used for initial access for access UEs and IAB nodes. In addition, to support topology formation, mobility/multi-connectivity procedures, and backhaul link management, periodic measurements and reports can be configured by a parent IAB node to a child IAB node UE function. This can comprise radio resource management (RRM), radio link monitoring (RLM), and beam management (L1-BM) measurements and reports.
The described technology is generally directed towards adapting the demodulation reference signal sent in a wireless resource data block based on channel estimation performance. In general, if the demodulation reference signal received was not successfully able to be used to demodulate the resource data block, the demodulation reference signal density can be increased up to a maximum density, which costs resource elements but improves the channel estimation accuracy. If the demodulation reference signal received was able to be used to demodulate the resource data block, the demodulation reference signal density can be decreased down to minimum density, which saves resource elements for data. The network device can use HARQ ACK/NACK data (e.g., a current count or counted over a time period) to determine channel estimation performance, and/or the user equipment can recommend a demodulation reference signal density change.
A joint channel estimation and data detection technique for decoding an uplink control channel using resource elements that are redundant in acknowledgement and negative acknowledgement uplink control channel transmissions is disclosed. To improve the performance of a decoder, channel estimation can be performed using reference signals (pilot symbols) to determine the characteristics of a channel at given locations within a subframe. For some uplink control channel formats, however, there aren't dedicated locations for reference signals/symbols, and so channel estimation is not performed. Since the acknowledgement and negative acknowledgement resource elements may be identical, at identical locations within the two different types of messages, the mobile device can replace the resource elements at the redundant locations with reference signals, thus the receiver can perform channel estimation using the reference signals, which can improve the performance of decoding the rest of the acknowledgement, negative acknowledgement transmission.
Various aspects of the technology described herein are directed towards a generalized beam management framework in which beam management takes into account interference to steer a beam. Aspects comprise configuring a report request comprising a resource setting with channel state information-reference signal resource data and an associated report setting with parameter data corresponding to the one or more channel state information-reference signal resources. The report request is configured to instruct a user equipment device to include interference information when performing user equipment device beam management and reporting. Upon receiving the report request, the user equipment performs a beam measurement operation that includes interference information when generating the beam management report sent to the network device.

The data 106 can be associated with a plurality of mobile communications devices 110 operating in communication with at least one base station of a mobile communications network 108 that serves the target data source location 112. The network data collection system 104 can collect the data 106 and provide the data 106 to the machine learning system 102.

FACILITATING FAST CHANNEL STATE INFORMATION COMPUTATION FOR 5G WIRELESS COMMUNICATION SYSTEMS
Fast calculation of channel state information using demodulation reference signals (DM-RS) is provided herein. Channel state information is traditionally calculated based on the channel state reference signals (CS-RS). Demodulation reference signals, which are used for channel estimation for a data channel, are transmitted at different times than CS-RS however, and so some portions of the channel state information including layer indicator (LI) and channel quality indicator (CQI) can be calculated based on the demodulation reference signals, allowing a network to adapt more quickly to changing channel conditions, without having to transmit a CS-RS. Generally, precoding matrix indicator and rank indicator, which cannot be determined based on the DM-RS, don't change as often and are more stable over time, thus do not need to be calculated as frequently as the LI and CQI.
Precoding coefficients can be compressed based on user equipment signal interference to noise ratio or path loss in front haul cloud radio access network systems. For example, a baseband unit can compute a precoder matrix from an estimated channel associated with an uplink signal. Once the baseband unit computes the channel, it can determine the coefficients for the linear combination of the basis vectors, which are known at the baseband unit and the radio unit as well. The baseband unit can estimate the path loss and the signal interference to noise ratio and determine the basis vectors. The baseband unit can then compress the coefficients and transmit the coefficients to the radio unit. When the radio unit receives the compressed coefficients, the radio unit can reconstruct the precoder matrix and apply to reference signals and data traffic channels.

A base station device can transmit data via multiple data channels to a single user equipment device. Each of the multiple data channels can be configured and scheduled via respective downlink control channels to the user equipment device. In an embodiment, the first data channel can be mapped to multiple layers, with a modulation and coding scheme (MCS) assigned based on the average channel quality indicator (CQI) of the layers. One or more of the layers can have a higher CQI however, capable of supporting an additional transmission. The base station device can then facilitate establishing a second data channel to the layer with the higher CQI. The MCS assigned to the second data traffic channel can be based on the CQI of the layer, or based on a difference between the average CQI of the layers and the CQI of the layer.

FACILITATION OF FREQUENCY SELECTIVE SCHEDULING FOR 5G OR OTHER NEXT GENERATION NETWORK
Sub bands can be scheduled with optimal modulation and coding scheme (MCS) when the user equipment reports the sub band channel quality indicator (CQI) and sub band pre-coding matrix index (PMI). The network can use multiple downlink control channels to indicate the sub band resources and the corresponding MCS for that resource allocation. By using multiple downlink control channels to indicate the sub band MCS, the network can use resources more efficiently.
The described technology is generally directed towards ultra-reliable low latency communications between a network device and a user equipment, using scheduling parameters for a less conservative block error rate threshold based on the spectral efficiency. A network device obtains channel state information comprising a rank indicator, a layer indicator indicating a strongest layer, a first channel quality indicator corresponding to a first coding rate and a first modulation value for a first conservative block error rate threshold value, and a second channel quality indicator corresponding to a second coding rate and second modulation value for a second conservative block error rate threshold value. When the network device determines that that the first coding rate and the first modulation value are suitable for ultra-reliable low latency communications, the network device schedules the user equipment to use the first coding rate and the first modulation value, e.g., using the strongest layer.
A bandwidth efficient way to improve reliability without introducing additional latency is provided for Ultra- Reliable and Low Latency Communications (URLLC) service in 5G NR. In particular, using rateless fountain codes in conjunction with packet duplication for split bearers at the Packet Data Convergence Protocol (PDCP) layer increases the reliability of transmission without the need for retransmissions, and with a lower bandwidth requirement compared to traditional packet duplication
The disclosed subject matter relates to techniques for transmitting reference signals in non-orthogonal multiple access (NOMA) communication protocols. In one embodiment, a method comprises determining a demodulation reference signal (DMRS) for use by a group of mobile devices in association with uplink data transmissions, wherein respective mobile devices of the group of mobile devices are configured to employ a same time and a same frequency resource of a wireless communication network in association with communicating with network devices of the wireless communication network according to a NOMA communication protocol. The method further comprises determining different configuration parameters for application by the respective mobile devices in association with transmitting the DMRS with the uplink data transmissions, wherein the different configuration parameters facilitate differentiating between the DMRS as transmitted by the respective mobile devices. The method further comprises sending the DMRS and the different configuration parameters to the respective mobile devices.
Time domain resource allocation is facilitated for a physical downlink shared channel. For instance, a physical downlink shared channel associated with a mobile device can be configured via a broadcast channel, and a data structure associated with the physical downlink shared channel corresponding to a physical downlink control channel can also be configured. The configured data structure can be sent to the mobile device to be utilized for physical downlink shared channel transmissions between the wireless network device and the mobile device. Additionally, the time domain resources can be allocated by transmitting a physical downlink shared channel transmission to the mobile device based on a condition associated with a radio resource control connection being determined to not have been satisfied.
The described technology is generally directed towards using a frequency-separated band as a supplementary uplink band for a new radio downlink band that cannot operate as a time division duplex band and otherwise has no paired uplink band. The paired bands are separated in frequency, yet operate in the time division duplex mode. The supplementary uplink for New Radio facilitates coexistence with LTE in the frequency division duplex spectrum.
The described technology is generally directed towards scheduling downlink transmissions using orthogonal resources (that is, resources that avoid or at least reduce interference) when a network configures a user equipment (UE) with a multiple slot configuration to repeat the HARQ-ACK information for a transmission. By using orthogonal resources, a downlink transmission can be scheduled in consecutive time slots instead of waiting for the repeated HARQ-ACKs to complete.
Failed transport blocks can be retransmitted when the number of layers is different compared to the number of layers for re-transmission. Mapping tables can be used for retransmitting the failed packets when a user equipment reported rank is different from the transmitted rank. In addition, an indication can be sent to the user equipment to indicate the failed transport blocks when the network decides to use a different codeword for transmitting a failed packet.
Various embodiments disclosed herein provide for indicating a number of codewords in a data traffic transmission. Depending on the number of layers of a data traffic transmission, the transmission can either comprise one codeword or two codewords. If there are two codewords included in a data traffic transmission, the transmitter can indicate the modulation code scheme and other information for each codeword in the first codeword and second codeword locations in the downlink control information data structure.

Various embodiments disclosed herein provide for a reciprocity based channel state information acquisition scheme for frequency division duplex wireless communications systems. By converting channel state information from a traditional frequency-time domain to a Delay-Doppler domain, the channel state information feedback overhead can be reduced since the multi-path of radio propagation is reciprocal in terms of each ray and each cluster of antenna elements. Since the surrounding objects create the same multipath fading for both uplink and downlink transmissions, modeling the channel state information in the Delay-Doppler domain, and adjusting the sign of the Doppler value (negative/positive) can account for the multipath characteristics in both uplink and downlink.
