Embodiments of the present disclosure disclose devices, methods and apparatuses for reconfiguration control. A terminal device receives, from a first network device, indication information on at least one reconfiguration performing condition related to data transfer status regarding one or more applications. Then, the terminal device performs a reconfiguration operation based on determining that the at least one reconfiguration performing condition is fulfilled. In this way, the terminal device may perform reconfiguration with an optimized execution time, thereby minimizing service disruption.
Embodiments of the present disclosure relate to data transmission for discontinuous connectivity. A terminal device receives, from an access network device, an indication that an acknowledgement for application data from the terminal device is to be deferred. The terminal device avoids retransmitting the application data based on the indication. As such, redundant retransmissions of the application data can be avoided.
Example embodiments of the present disclosure relate to positioning enhancements. A first device receives, from a second device providing a serving cell for the first device, a configuration of a plurality of SRS triggering states associated with a plurality of SRSs on a group of bandwidth parts. The first device receives, from the second device, an indication of a target triggering state of the plurality of SRS triggering states. The first device then transmits, based on the target triggering state, the plurality of SRSs on at least a part of the group of bandwidth parts sequentially. In this way, SRS transmissions across multiple SRS resources or SRS resource sets withing multiple BWPs can be triggered in a frequency hopping manner via single DCI, which reduces the signaling overhead and latency, and improve the positioning efficiency.
Embodiments of the present disclosure relate to certificate management for network functions (NFs). A first core network device receives, from a second core network device, status information of a certificate of the second core network device. The first core network device further stores the status information in a profile of the second core network device. As such, with the status information of the certificate being stored in the profile of the second core device, the certificate of the second core device can be managed in association with the second core network device itself, thereby improving efficiency of certificate management for the NFs.
Embodiments of the present disclosure relate to improvement of accuracy of angle based positioning. A terminal device receives a plurality of beams from an access network device. The terminal device determines a time offset referenced to a slot start reference which is synchronized to the access network device and a received power level for each of the plurality of beams. The terminal device transmits, to the access network device, a list including the determined time offset and the received power level respectively, and a corresponding beam identity (ID) for each of the plurality of beams. The list of beams is utilized by an access network device to determine a position of the terminal device using an angled based positioning method.
Embodiments of the present disclosure relate to method, device and computer readable media for sidelink communications. A first device determines whether in-band emission (IBE) will degrade a reception of a first transmission from the first device or a second transmission from a second device, wherein the first transmission and the second transmission are to be performed on a first slot and in a first transmission band. If the in-band emission will degrade the reception, the first device changes a first starting point of the first transmission.
Embodiments of the present disclosure relate to devices, methods, apparatuses and computer readable storage media of cell selection. A first device receives, from a second device, an indication of a cell list associated with a feature and at least one of an allowed cell list or an excluded cell list. The first device determines, based on a capability of the first device, at least one of the following: one or more allowed cells for the first device based on one or more cells in the allowed cell list and one or more cells in the cell list associated with the feature, or one or more excluded cells for the first device based on one or more cells in the excluded cell and one or more cells in the cell list associated with the feature. As such, separate cell reselection control for devices supporting and not supporting new feature (s) is provided.
Example embodiments of the present disclosure relate to controlling a process towards a cell with a duplex operation. A method comprises: receiving, at a first device from a second device, at least one of a first set of values and a second set of values for a parameter set associated with a process towards a cell; determining whether a condition associated with a duplex operation is met; and in accordance with a determination that the condition is met, at least applying the second set of values to the process towards the cell.
Methods and apparatus are disclosed for protecting information for a SoR procedure initiated by a user equipment (UE). A method comprises, creating at a UE, a first secured packet which is protected with one or more keys, wherein the first secured packet comprises enhanced steering of roaming (SoR) related information for triggering a SoR procedure; and sending from the UE to a first visited public land mobile network (VPLMN), a message comprising the first secured packet. Each of the one or more keys is a symmetric key, which is available for the UE and a home public land mobile network (HPLMN) of the UE before a primary authentication of an initial registration to the first VPLMN.
Inter-alia, a method is disclosed comprising: obtaining a request for measuring at least a combined carrier aggregation error, CAE of one or more component carriers, CCs, configured for the apparatus in a mobile communication network, wherein the combined CAE is indicative of a total of one or more errors resulting from at least one of a transmit error, receive error, or a processing of the one or more CCs; obtaining, based on the request, at least one of one or more positioning reference signals, PRSs, or one or more sounding reference signals, SRSs, of the one or more CCs; determining, based, at least in part, on at least one of the obtained one or more PRSs, or the one or more SRSs, the combined CAE; and providing the determined combined CAE. It is further disclosed an according apparatus, computer program and system.
