Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may receive a configuration indicating a resource pool and a channel occupancy control parameter for configured grant sidelink communications, select one or more resources from the resource pool based at least in part on the channel occupancy control parameter, and transmit a configured grant sidelink communication using the one or more resources from the resource pool. Numerous other aspects are provided.

In a communication system in which a base station and a terminal communicates, the base station and the terminal communicates efficiently. There is provided the terminal which communicates with the base station, the terminal including: a reception unit 605 which detects a transmission power control (TPC) command in a downlink control information (DCI) format and obtains a power correction value from the TPC command; and a transmission power control unit 6015 which sets transmission power of an uplink signal based on a power correction value obtained from a first TPC command when the terminal is in a first state and sets transmission power of the uplink signal based on a power correction value obtained from a second TPC command when the terminal is in a second state.

Disclosed are a method, network device, and system for transmit power control during D2D communication. The method comprises: a network device determines the maximum allowed transmit power of a first terminal on the basis of the maximum level of interference that a cellular network can handle and/or the maximum level of interference that the first terminal is allowed to cause to a receiving terminal, and sends said maximum allowed transmit power of the first terminal to the first terminal, said first terminal being the sending device of D2D communication; and the first terminal determines transmit power on the basis of said maximum allowed transmit power. By means of the present technical solutions, when determining transmit power, a D2D sending device takes into account the maximum interference a cellular network can handle and/or the maximum level of interference that may be caused to a receiving terminal, thereby reducing the interference caused to D2D communicating terminals or to terminals of other cells using the resources of a cellular network.

A semiconductor integrated circuit for a radio communication terminal sequentially uses a plurality of frequency channels by instructions from a hopping frequency decision unit to receive packet data by a reception unit. When the integrated circuit cannot detect the head of the packet data in reception operations, the integrated circuit cannot receive packet data should be received originally then assumes that the received packet data is a packet error. And the integrated circuit calculates packet error rates for each frequency channel on the basis of the number of times of reception operations performed for each frequency channel and of the number of times of packet errors to estimate channel qualities by using the packet error rates.

An apparatus implemented in a master access point (AP) selects at least one basic service set (BSS) from one or more neighbor BSSs to form a spatial reuse group (SRG). The apparatus then performs coordinated spatial reuse (CSR) in the SRG with a set of overlapping basic service set (OBSS) power detection (PD) parameters.

Methods and apparatuses for power control are disclosed. A method comprises: receiving a first signaling indicating one or multiple power values for a downlink reception from a node, each power value being associated with a spatial domain filter, and determining a power value for the downlink reception from the node.
