A wireless communication node sets a downlink target value of a received power of a downlink from an upper node based on a received power of an uplink from a lower node, and transmits, to the upper node, power control information based on the downlink target value.

The present disclosure provides a method for reducing a spurious-emission interference, comprising: determining a target link in wireless communication mode, a value of a spurious-emission effect evaluation parameter of the target link in wireless communication mode exceeding a preset range; detecting whether the spurious-emission effect evaluation parameter is an impact factor for a throughput performance evaluation parameter of the target link in wireless communication mode; determining at least one cause factor causing the value of the spurious-emission effect evaluation parameter to exceed the preset range; and controlling a preset spurious-emission regulation module matching the cause factor to regulate the cause factor, so that the value of the spurious-emission effect evaluation parameter is within the preset range.

A mobile ad hoc network (MANET) includes a first MANET node having a first radio frequency (RF) transceiver and a first controller coupled thereto to generate RF transmissions. A second MANET node has a second RF transceiver configured to communicate with the first RF transceiver, and a second controller coupled to the second RF transceiver. The second controller is configured to cooperate with the second RF transceiver to receive the RF transmissions from the first MANET node, generate a normalized reception value based upon the received RF transmissions and send the normalized reception value to the first MANET node. The first controller is configured to control a transmit power level for a subsequent RF transmission based upon the normalized reception value from the second MANET node.

A resource configuration method includes: receiving power indication information reported by user equipment; and configuring, for the user equipment, a coverage compensation resource used when performing data transmission on the basis of a target maximum power level according to the target maximum power level indicated by the power indication information.

This application provides an uplink information transmission method and apparatus. The method includes: determining a value of a power control parameter in a value set of the power control parameter, where any value set of the power control parameter includes at least two values; sending indication information to a terminal device, where the indication information is used to indicate the value of the power control parameter; and receiving uplink information, where the uplink information is from the terminal device at a transmit power adjusted based on the value of the power control parameter.

Methods, systems, and devices for wireless communication are described. Generally, the described techniques provide for efficiently performing and reporting reference signal received power (RSRP) measurements. In particular, the techniques described herein may allow a user equipment (UE) to efficiently identify reference signals on which to perform RSRP measurements (e.g., based on signaling from a base station), identify when to report RSRP measurements (e.g., aperiodically, periodically, or semi-persistently), and identify a channel on which to report RSRP measurements (e.g., a sidelink channel or an uplink channel). In addition, the techniques described herein may also allow a UE to efficiently identify open loop parameters to use to determine an appropriate transmit power for transmitting to another UE over a sidelink.

A device including one or more processors configured to: determine a disconnection margin value based on: a current transmission operation state including one or more transmission control parameters, and a current transmission rate; receive a power back-off (PBO) request including a PBO value; perform a comparison of the PBO value to the disconnection margin value; and determine whether to apply a PBO according to the PBO request based on the comparison.

An electronic device comprising circuitry that controls transmitting signals through a first communication link toward a base station or a second communication link toward a mobile station. The second communication link uses an uplink resource of the first communication link. The circuity determines transmission power for the second communication link based on a first parameter and a second parameter. The first parameter indicates a signal level, a power level, or a noise level in the first communication link. The second parameter corresponds to path loss information for the first communication link.

Apparatuses and methods for transmission power control are disclosed. A given transmission resource and a first transmission power are determined (202, 204) for transmission. Prior to transmitting on the given transmission resource it is determined (206) whether the resource is occupied or unoccupied. Upon detecting that the resource is occupied, a second, reduced transmission power is determined (210) such that a transmission using the second, reduced transmission power would not render the resource as occupied. The determination of the second transmission power is based at least partially on a predetermined maximum transmission power reduction value. Transmission (212) is done utilising the given transmission resource using the second transmission power according to the determination.

Novel techniques for pooling the available transmit power of a beam across the subcarriers that are or that are scheduled to be in use (and not across all available subcarriers) are disclosed. The scheduled subcarriers may be located in the same or different carriers of a modulation transmitter modulation system, and the pooled transmit power may be allocated or distributed across the scheduled subcarriers of the beam. Modulation symbols or resource elements may be transmitted in accordance with allocated, per-subcarrier power budgets, thereby maximizing the SNIR of signals that are transmitted in the beam via the scheduled subcarriers. Additionally, the allocation of the pooled transmit power to various subcarriers may continuously and/or dynamically vary over time, e.g., based on traffic demands, interference characteristics, etc., as well as based on subsequent scheduling of subcarriers to transmit subsequent modulation symbols or resource elements.
