A wireless access point managing apparatus that includes a radio, and wireless communication control circuitry that communicates information via the radio between the wireless access point managing apparatus and one or more electronic devices so as to provide a wireless access point to a network for the electronic devices. Processing circuitry performs access point management including: communicating with a separate apparatus that provides another wireless access point to the network; performing a determination as to whether shutdown of the wireless access point of the separate apparatus is appropriate; and sending a shutdown instruction to the separate apparatus if shutdown is determined to be appropriate, the shutdown instruction being an instruction to cause the separate apparatus to shut down a wireless access point radio in the separate apparatus.

A wireless device receives control message(s) comprising parameters of a plurality of cell groups and a pathloss reference for each secondary cell. The wireless device transmits uplink signals in a first secondary cell in a secondary cell group. Transmission power of the uplink signals is determined employing a received power of the pathloss reference assigned to the first secondary cell. Timing of the uplink signals in the secondary cell group employs a synchronization signal on an active secondary cell in the secondary cell group as a timing reference.

Certain aspects of the present disclosure provide techniques and apparatus for operating a wireless communication device pursuant to radio frequency (RF) exposure compliance. A method that may be performed by a wireless device includes determining a first budget for one or more radios. The method also includes converting the first budget to a second budget for the one or more radios in response to a transition from a first maximum time-averaged RF exposure limit with a first time window to a second maximum time-averaged RF exposure limit with a second time window. The method further includes transmitting a signal with the one or more radios at a transmit power determined based at least in part on the second maximum time-averaged RF exposure limit and the second budget.

An access point in a geographic routing system and a controlling method thereof are provided. The controlling method of the access point in the geographic routing includes the following steps. A traffic event packet is received by the access point. A back-off timer of the access point is set to be a first back-off time value. The first back-off time value is less than a second back-off time value of any on board unit (OBU) which receives the traffic event packet. The traffic event packet is broadcasted by the access point when the back-off timer is counted down to be zero.

Systems and methods for controlling uplink power in a non-terrestrial network (NTN). An NTN station transmits a reference signal at a first time having a defined transmission power and the reference signal is received by non-terrestrial user equipment. The user equipment evaluates the reference signal and determines a first downlink loss of the reference signal by calculating a difference between a measured power level of the received reference signal and the defined transmission power. The NTN station transmits a communication signal at a second time and is received by the user equipment, which estimates a second downlink loss of the communication signal based on the first downlink loss and a power level of the communication signal. A first uplink loss is estimated based on the second downlink loss, and the user equipment adjusts a transmission power of its transmitter based on the first uplink loss.

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.

Techniques for determining beam-sweeping patterns for synchronization signals transmitted in a region by several access nodes in a network, where each access node is connected to a corresponding array of antenna elements. An example method includes modeling a total power function for the power transmitted in the synchronization signals, as a factor graph having a plurality of check nodes and variable nodes, each check node corresponding to a virtual wireless device in the region and each variable node corresponding to an available beam for an access node. The virtual wireless devices are emulated so as to implement quality-of-service constraints on synchronization signals received by the virtual wireless devices. An iterative message-passing algorithm, such as a min-sum algorithm, is applied to the modeled total power function, to determine a sequence of power levels, for each access node, for sweeping synchronization signal beams, so as to minimize the total power function.

Systems and methods are disclosed that provide a closed loop power control system including adaptively adjusting the desired target SINR over time so as to ultimately achieve a feasible SINR. In one implementation, a method is provided of optimizing uplink closed loop power control in a RAN in which one or more base stations each service a plurality of mobile stations, including: determining a power level for each mobile station for its respective uplink transmissions, including measuring a current achieved SINR for each mobile station; and for each mobile station, adjusting the power level to be sufficiently high to meet desired transmission characteristics but not so high as to cause unnecessary interference with transmissions from other mobile stations, by adjusting a desired target SINR based on factors selected from the following: current and prior achieved SINRs, current and prior interference measurements, and current and prior transmission power control commands.
