The AAS comprises a plurality of antenna elements and one or more radio frequency integrated circuits, RFICs. Each of the one or more RFICs is associated with one or more of the plurality of antenna elements. The method comprising: capturing a plurality of signal samples of one or more signal chains of each of the one or more RFICs.

The performance and ease of management of wireless communications environments is improved by a mechanism that enables access points (APs) to perform automatic channel selection. A wireless network can therefore include multiple APs, each of which will automatically choose a channel such that channel usage is optimized. Furthermore, APs can perform automatic power adjustment so that multiple APs can operate on the same channel while minimizing interference with each other. Wireless stations are load balanced across APs so that user bandwidth is optimized. A movement detection scheme provides seamless roaming of stations between APs.

In a wireless network that includes mobile users (such as vehicles), the signal quality is constantly changing due to changing distances from the base station, variable attenuation factors such as passing obstructions, and beamforming in 5G and 6G networks. An automatic algorithm can compensate for transmission variations by adjusting the transmission power of the base station and/or the mobile user device, to account for the current location and motion of the mobile user device. The radio attenuation factor can be measured throughout the base station's region, and the attenuation map can be used to boost downlink power to vehicles in dead zones, while saving power in regions of good receptivity. The base station can thereby maintain the expected QoS despite motions. An AI model may be used to select the optimal power level.

A parameter server located at a base station may coordinate federated learning among multiple user equipment (UEs) using over-the-air (OTA) aggregation with power control to mitigate aggregation distortion due to amplitude misalignment. The parameter server may select a first group of UEs for a first OTA aggregation session of a federated learning round based on a common received power property of each UE in the first group of UEs. The parameter server may transmit a global model to the first group of UEs. Each UE in the first group may train the global model based on a local dataset and transmit values associated with the trained local model. The parameter server may receive, on resource elements for the first group of UEs, a first aggregate amplitude modulated analog signal representing a combined response from the first group of UEs.

Wireless networks with plural nodes having a respective transceiver and a processor configured to, and methods to, obtain current state data, calculate a reward, store such state data and rewards in a collected parameters database, provide such current state data and data from such collected parameters database to a reinforced neural network, select an action using the reinforced neural network, and output the action to the respective transceiver so as to selective modify its transmit power level.

A transmit power determining method and apparatus are disclosed. The method includes: calculating, channel state information of a channel between the wireless access point device and a station device within a particular time range; comparing, by the wireless access point device, the channel state information with pre-obtained reference channel state information, and adjusting, according to a result of the comparison, a transmit power currently used by the wireless access point device; and sending, by the wireless access point device to the station device by using a transmit power after the adjustment, a message carrying data. During implementation of the present disclosure, a transmit power for sending data can be adjusted according to channel state information corresponding to a channel between a wireless access point device and a station device, thereby avoiding unnecessary power overheads and a waste of energy.

Various embodiments disclosed herein provide for a power control system in a multi-hop integrated access and backhaul network. In the multi-hop integrated access and backhaul network, a donor node can communicate with user equipment devices and relay nodes that have varying power levels; and to avoid receiving uplink transmissions with varying power levels which can impact automatic gain control systems and lower overall throughput, the power control system can manage the power levels of the relay node in order to reduce the difference in power levels. The power control system can schedule relay node devices to transmit uplink transmissions alongside user equipment devices that have a high signal strength; schedule relay nodes and user equipment devices to separate symbols within a time slot; and/or perform closed loop power control management at the relay node to reduce the power level for an uplink transmission.

A technique is disclosed for reducing a number of transmissions of power control signals to a wireless device in a communication network. The technique is performed in the communication network or a network node and involves the determining if the wireless device is implementing a routine for discarding a power control signal. The technique further involves the reducing of the number of transmissions of power control signals to the wireless device based on the determining if the wireless device is implementing a routine for discarding a power control signal.
