In a method implemented at a network device, the method comprising allocating, at a network device, available resource block groups RBGs to a plurality of terminal devices; determining the number of shared RBGs in the available RBGs, the shared RBGs being shared by the plurality of terminal devices; determining a sum of shared number of the shared RBGs per each of the plurality of terminal devices; determining an average value of the transmit power base on the number of available RBGs and a total power of the network device, the average value indicating a basic power allocated by the network device to the plurality of terminal devices; determining an offset value of a transmit power for each of the plurality of terminal devices based on the number of shared RBGs, the sum of the shared number and the average value; and determining a target value of the transmit power for each of the plurality of terminal devices based on the offset value and the average value.

Methods, systems, and devices for wireless communications are described. A user equipment (UE) may transmit a first sensing signal of a radio frequency (RF) sensing procedure at a first transmit power. The UE may receive, from a base station at least in part in response to the first sensing signal, a power control message for sensing signals of the RF sensing procedure. The power control message may indicate a power control strategy for transmitting sensing signals of the RF sensing procedure. The UE may then transmit, at a second transmit power based on the received power control message, a second sensing signal of the RF sensing procedure.

User equipment includes an antenna, a controller, a transmitter, and a receiver. The transmitter sends a first radio frequency signal for communication with a primary cell to the antenna according to a first timing advance set by the controller, and sends a second radio frequency signal for communication with a secondary cell to the antenna according to a second timing advance set by the controller. The receiver sends received data to the controller including information regarding at least one of the first timing advance and the second timing advance. The first timing advance indicating a first uplink transmission timing alignment value and the second timing advance indicating a second uplink transmission timing alignment value.

The present invention relates to a wireless communication system, specifically to a method comprising the steps of configuring a PCell of a licensed band and an SCell of an unlicensed band for a base station; receiving resource configuration information concerning the SCell by means of a physical downlink control channel (PDCCH) of the PCell; configuring a subframe set within a temporary time duration on the SCell on the basis of the resource configuration information; and communicating with the base station by means of the subframe set temporarily configured on the SCell, and to an apparatus for the method.

A system (1) for selecting one or more devices in a wireless network for transmitting, receiving and/or processing a radio frequency signal for presence and/or location detection comprises at least one processor (5) configured to determine a suitability of each of a plurality of devices (11-15) for transmitting, receiving and/or processing a radio frequency signal for presence and/or location detection, select a subset of devices from the 5 plurality of devices based on the suitability determined for each of the plurality of devices, and instruct at least one of the subset of devices to act as a device for transmitting, receiving and/or processing a radio frequency signal for presence and/or location detection.

Embodiments of the present disclosure provide a wireless communication method and device, and a network device. A wireless communication method includes: determining a target reception power value; performing control on at least one of a first transmission power or a second transmission power according to the target reception power value, thereby enabling a difference between a first reception power and a second reception power to be less than a preset power threshold. A wireless communication method includes: determining a reference time; performing control on at least one of a first transmission time or a second transmission time according to the reference time, thereby enabling a difference between a first reception time and a second reception time to be less than a preset time difference.

Embodiments of a method in an access node of a wireless communication network pre-emptively reduces intercell interference, ICI, in neighboring cells. The access node is configured to transmit downlink traffic to a plurality of user equipments, UEs, in a coverage area of the access node. At least one unscheduled physical resource block, PRB, is detected. Downlink traffic across is diluted across the at least one unscheduled PRB. Finally, transmission power of scheduled PRBs is reduced.

Systems and methods are described for reducing processing time of messages that are repeatedly received, with increasing frequency, by a device (e.g., user equipment, base station etc.). For example, the systems and methods would have a base station decrease power, possibly to minimum power-out, per policy, if messages beyond the original are received and the time between those messages is decreasing. The decrease in time between messages indicates a more urgent need for the base station to power down. The systems and methods can be adapted for different types of messages (e.g., power-up, power-down, resource request, bandwidth request, service type, call type origination, quality-of-service request, application type, etc.). Each message type is associated with a policy (pre-determined or adaptive) that indicates the default behavior when the method detects a decrease in time between messages.

A user terminal according to one aspect of the present invention is characterized by having a receiving section that receives a power control ID, a control section that controls transmit power according to a transmit power parameter set specified by the power control ID, and a transmitting section that transmits a signal corresponding to an object set specified by the power control ID, using the transmit power. According to one aspect of the invention, it is possible to suppress a reduction in communication throughput, even in the case of using beam specific transmit power control.

This application discloses example power control methods and apparatuses. One example method includes receiving, by a first node, first information sent by a second node, where the first information is used to determine a first transmit power, where the first transmit power is a power used when the first node sends downlink information to the second node through a first link, where the first link is a link between the first node and the second node, and where the first node is an upper-level device of the second node. The first node can then determine the first transmit power based on the first information.
