Embodiments of the present disclosure provide methods and apparatus for power control in random access procedure. A method implemented at a terminal device comprises obtaining at least one power control parameter to be used for a request message for a contention free random access, CFRA. The method further comprises transmitting, to a network node, the request message for the CFRA. A power of the request message for the CFRA is controlled based on the at least one power control parameter. The request message comprises: a random access channel, RACH, preamble and a physical uplink shared channel, PUSCH.

There is provided a method in a wireless device. The method comprises: receiving a Media Access Control (MAC) Control Element (CE) from a network node, the MAC CE comprising a plurality of octets and a plurality of fields, wherein a first field of the plurality of fields is used to indicate a number of sets of power control parameters in a last octet of the received MAC CE, the sets of power control parameters being associated with a reference signal used for path loss estimation; and sending a transmission to a network node, based at least on a set of power control parameters associated with the reference signal.

A method of wireless communication may include monitoring, by a first device, a medium for frames in response to preparing to transmit a first frame to a second device. The method may also include while monitoring the medium and before transmitting the first frame, obtaining a second frame transmitted by a third device in the medium and adjusting a transmission of the first frame to the second device in the medium based on obtaining the second frame.

A wireless device receives one or more configuration parameters including a plurality of sidelink feedback resources, where at least two sidelink feedback resources, of the plurality of sidelink feedback resources, are associated with different values for received signal power, and each of the at least two sidelink feedback resources are at least one of a time resource or a frequency resource. The wireless device selects, based on a received signal power of the different values for the received signal power, a sidelink feedback resource from the at least two sidelink feedback resources. The wireless device transmits a sidelink feedback signal, to a second wireless device, via the sidelink feedback resource.

A power control method and apparatus and a terminal device are disclosed, which pertain to the field of communication technologies. The power control method of this application includes: obtaining a first path loss, where the first path loss is determined based on at least one of a sidelink SL path loss or a downlink DL path loss; and controlling a transmit power of a target transmission on a sidelink based on the first path loss.

The present application relates to devices and components including apparatus, systems, and methods for power headroom reporting in integrated access and backhaul nodes.

A power control method and apparatus, and a service node, a terminal device and a storage medium are disclosed. The method may include: transmitting configuration information, which is used for indicating N power parameter sets, where N is a positive integer; and receiving uplink data, where the transmission power of the uplink data is determined by a terminal device according to the configuration information.

A user equipment (UE) receives a transmit power control (TPC) command and is configured to accumulate the TPC command with prior TPC commands to derive a first value. Further, the UE is configured to produce a second value based on a type of a first signal to be transmitted and a third value based on a transport format of the first signal, wherein the type of signal is from a plurality of types of signals having different spreading factors. The UE is configured to determine a transmission power level for the first signal based on the first value, the second value and the third value. The UE is configured to transmit the first signal at the determined transmission power level.

A method for PH calculation and a terminal are provided. The method includes: receiving a path loss reference change indication; and calculating a PH by using a specific path loss reference, where the specific path loss reference includes a path loss reference before receiving the path loss reference change indication, or a changed path loss reference indicated by the path loss reference change indication.

The present disclosure relates to a pre-5th-Generation (5G) or 5G communication system to be provided for supporting higher data rates Beyond 4th-Generation (4G) communication system such as Long Term Evolution (LTE). A power control method, and a terminal for performing power control. The power control method includes: acquiring parameter configuration information for sidelink open loop power control; transmitting a sidelink physical channel or a sidelink physical signal to a second UE, so that the second UE measures a Reference Signal Received Power (RSRP) based on the received sidelink physical channel or the sidelink physical signal, and feeds back the measured RSRP to a first UE; receiving the RSRP fed back by the second UE; calculating an open loop transmitting power based on the received RSRP and the acquired parameter configuration information for sidelink open loop power control.
