A wireless station is allocated use of a time slot in a given direction, uplink or downlink, on a given channel. The wireless station monitors for presence of wireless energy during a portion of the time slot. Based on a detected level of the wireless energy in the time slot, the wireless station controls transmission of wireless communications in a direction opposite to the configured direction in a remaining part of the time slot.
An access point (AP) communicates to one or more stations (STAs) information indicating a set of channels and/or resource units (RUs), corresponding to a wideband basis service set (BSS) for an authorized unlicensed radio local area network (RLAN) using 6GHz spectrum, which are subject to a lower power spectral density (PSD) level than other portions of the BSS frequency range or are not to be used for transmission. In some, but not necessarily all, embodiments, the AP and the STAs do not encode data on the identified channels or RUs, but do encode data on other channels and/or other RUs, which are not subject to the lower PDS constraint.
A radio access network (RAN) for a wireless communication network transmits, to user equipment (UE), information about NPN services provided by a non-public network (NPN) supported by the wireless network, where the UE is not subscribed to the NPN. In some embodiments, the NPN service information is periodically broadcasted to the UE; in other embodiments, the information is transmitted in response to receiving a request from the UE. In response to receiving the NPN service information, the UE transmits and the RAN receives an on-boarding request from the UE to on-board the UE to the NPN, which the RAN forwards to an on-boarding network (OBN) of the wireless network. In response, the RAN receives NPN credentials for the UE from the OBN, which the RAN forwards to the UE, which uses the NPN credentials to register to the NPN, thereby enabling the non-subscribing UE to subscribe to the NPN.
A system includes multiple techniques of implementing listen before talk functionality to provide multiple mobile communication devices connectivity with a wireless base station.
A first radio of a wireless, e.g., dual-SIM DSDS, device communicates wirelessly with a first, e.g., 5G CBSD, base station of a first service provider using a first spectrum type, e.g., PAL or high- or low-bandwidth GAA, while a second radio communicates wirelessly with a second, e.g., 5G non-CBSD gNB, base station of a second service provider using a second spectrum type. The first radio informs the second radio of the first spectrum type assigned to the first radio, and the second radio transmits, to the second base station, capability information for the second radio based on the first spectrum type, that capability information being used by the second base station in assigning the second spectrum type to the second base station, thereby enabling equivalent QoS to be rendered to both radios even when the first service provider cannot directly control the QoS provided by the second service provider.

An access point aggregates information, e.g., from messages being communicated between the access point and client devices being serviced by the access point, and generates reports. The generated reports are communicated to a control device, e.g. a radio resource management (RRM) device. In some embodiments, generated reports include one or more of: i) message header information, e.g. resource unit (RU) allocation and/or use information and/or BSS color information, ii) collision reports, iii) received signal strength indicator (RSSI) reports, signal to noise ratio (SNR) reports, iv) interference reports; v) power information; vi) access point measurement information; and vii) access point control information. The control device uses the received reports from APs, in making bandsteering decisions with regard to individual client devices, and channel change decisions with regard to access points.
A method for Internet of Things (IoT) network security includes collecting information for each network device (device), determining a minimum viable resource allocation for each device based on the information, which defines the minimum resources needed by each device to engage the IoT network and handle data, and for each device, distributing minimum viable resource allocations and rules, determining monitoring sets, monitoring using the monitoring set, collecting updated information based partially on the monitoring set, analyzing the updated information to determine trends and insights relative to the devices and the IoT network, updating the monitoring set, minimum viable resource allocation, and rules based on the analyzed updated information, checking compliance with a current minimum viable resource allocation and rules, identifying devices having violations, and performing same on a continuous as it and automatic basis.

The control server associates the EP device with a single target gateway and/or uses EP transmission power control training iterations to reduce the EP transmission power level until the EP device is only able to successfully communicate its wireless signals to a single gateway.
