In a wireless communication system, there are several wireless channels used for communication between users and a base station. Channel characteristics may be defined by whether a channel is carrying traffic data and the timing of the channel transmissions with respect to channels not carrying traffic data. Different power levels between channels carrying traffic data or not may be defined and individual power levels of each channel may be amended based on individual power level command responses.

A Wireless-Fidelity (Wi-Fi) communication control method of a vehicle includes: determining a Wi-Fi communication state of the vehicle at a current position; selecting a Wi-Fi channel having a low communication load according to the Wi-Fi communication state of the vehicle at the current position; and forming a Wi-Fi zone in the vehicle using the selected Wi-Fi channel.

Methods and apparatuses are provided that include calibrating transmit power of a femto node based on measuring one or more parameters related to usage of the femto node. The femto node can temporarily increase transmit power and analyze received measurement reports to determine a transmit power calibration. The femto node can additionally measure uplink received signal strength indicators over multiple time periods following handover of a user equipment (UE) to determine whether to increase transmit power to cover the UE.

A wireless first device may receive a packet from another device from an overlapping basic service set (OBSS). A received power of the packet may be greater than a threshold for transmitting during the time of the packet. If the first device reduces its transmit power, the first device may increase the threshold. If the received power is less than the increased threshold, the first device may count down a backoff count during a transmission time or transmission opportunity of the packet. In some cases, after the transmission time or transmission opportunity, the first device may increase its transmission power. In some cases, the condition for counting down a backoff count may also include initiating or finishing the transmission during the transmission time or the transmission opportunity of the packet, or transmitting at the reduced power.

Provided is a method and apparatus for discontinuously transmitting/receiving packets for low-power consumption of a terminal in a cellular system for packet transmission. The present invention provides a method and apparatus that can perform a low-power consuming operation when a terminal is in active state in a cellular system. The method for discontinuously transmitting/receiving packet data to reduce power consumption of a terminal in a cellular system, including the steps of: a) establishing discontinuous transmission/reception (DTX/DRX) parameters including discontinuous DTX/DRX cycle information for terminals operating in a transmission suspension mode, which is a sub-state of an active state; and b) performing DTX/DRX based on the DTX/DRX parameters in the terminals operating in the transmission suspension mode.

A signal sending method and apparatus, a signal receiving method and apparatus, and a storage medium. The method comprises: sending resource configuration information, which includes a first configuration resource and a second configuration resource; sending a first signal on the basis of the resource configuration information, and a first node group and a second node group monitor a first signal on the basis of respectively corresponding configuration resources; generating and sending a second signal, the second signal being sent on a sending resource indicated by the first signal, and the node groups receive the second signal after the first signal is monitored. Nodes are grouped, and respectively corresponding configuration resources are respectively configured for the node groups; the first signal is sent on the basis of the configuration resources, and the first signal carrying the sending resource to instruct the nodes to receive the second signal, to reduce a collision problem in multiple P-RNTI configurations, avoiding invalid paging monitoring of the nodes, and saving the power consumption of the nodes.

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive downlink control information conveying at least one transmit power control (TPC) command. The UE may transmit a communication using a transmit power based at least in part on the at least one TPC command and a power mode. Numerous other aspects are described.
