Power control for a bidirectional Sidelink (SL) is provided. Solutions proposed herein limit the Physical SL Feedback Channel (PSFCH) transmit power level to that of the power level used for Physical SL Shared Channel (PSSCH) so as to prohibit too high transmit power for the PSFCH. In addition, if the difference between the PSSCH and PSFCH exceeds a preconfigured threshold (e.g., the PSFCH is too low), a Receiver (Rx) User Equipment (UE) can take preventive actions that ensure sufficient quality over the PSFCH. In further embodiments, both UEs continuously maintain the estimated SL Path Loss (PL) and transmit a single SL Channel State Information Reference Signal (SCSI-RS), and associated measurement reports rather than triggering new SCSI-RS transmissions and measurement reports for each PSSCH and associated PSFCH channel per SL (e.g., PC5) connection.

A user equipment that supports a first set of beams accumulates transmit power control (TPC) commands to generate an accumulated correction factor during communication between the user equipment and a base station that supports a second set of beams. The user equipment is configured to use a first subset of the first set of beams during the communication and the base station is configured to use a second subset of the second set of beams during the communication. The user equipment detects a change in the first subset or the second subset. The user equipment resets the accumulated correction factor in response to detecting the change. In some cases, the user equipment generates a plurality of correction factors for a corresponding plurality of closed-loop processes. The user equipment resets some or all of the plurality of correction factors in response to detecting the change.

This document describes methods, devices, systems, and means for user equipment-autonomously triggered-sounding reference signals. A user equipment maintains a connection to a first base station. In implementations, the user equipment generates link quality parameters for each broadcast signal in a set of broadcast signals received from a set of base stations and selects one or more base stations to include in an active coordination set (ACS). The user equipment then identifies a sounding reference signal (SRS) air interface resource that corresponds to the selection and requests the inclusion of the selected base stations in the ACS by autonomously transmitting, to the first base station, an uplink SRS using the identified SRS air interface resource. In implementations, the user equipment communicates over a wireless network using the active coordination set formed with the selected one or more base stations.

Indicating to a receiver node in a network that the receiver node should begin tracking signal to noise ratio (SNR) of a received signal for a new power and rate (PAR) interval for data sent from a transmitter node. A method includes determining that a new PAR interval is beginning. The method further includes adding an identifier to a data block. The identifier corresponds to the new PAR interval. The method further includes sending the data block from the transmitter node to the receiver node, where the receiver node will use the identifier to determine that a new tracking interval of SNR should be performed for the data block and subsequent data blocks having the identifier.

A method for improving transmission power management with compliance to regulations of radiofrequency exposure, which may comprise: at a current time, estimating whether a window average power, which may reflect average power transmitted using a radio technology during a moving time window, will exceed a power limit after the current time; if true, proceeding to at least one of a first handling subroutine and a second handling subroutine to set a power cap, and causing power transmitted to be capped by the power cap after the current time. The first handling subroutine may comprise: scheduling to set the power cap lower at a scheduled time. Estimating whether the window average power will exceed the power limit may involve discarding one of a plurality of power records. The second handling subroutine may comprise: setting the power cap not higher than the discarded one of the plurality of power records.

An embodiment of the present invention proposes a method for transmitting a signal by a first user equipment (UE) in a wireless communication system, the method comprising the steps of: receiving, by the first UE, information indicating a first interference from at least one second UE; receiving, by the first UE, information indicating a second interference and information on an SNR from a third UE; and when a condition is satisfied, transmitting, by the first UE, the signal to the third UE, wherein the first interference is an interference to the at least one second UE, which is caused by the first UE, the second interference is an interference to the third UE, which is caused by the first UE, and the condition is based on at least one of the first interference, the second interference, and the SNR.

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a source UE, a first sidelink communication. The UE may generate a transmit power control command based at least in part on a signal to interference noise ratio measurement associated with the first sidelink communication. The UE may transmit, to control a transmit power for a second sidelink communication, the transmit power control command to the source UE. Numerous other aspects are provided.

A system comprises an infrastructure element including a computer programmed to communicate with a first stationary communication node having a first directional short-wave antenna with a first field of view and a second stationary communication node having a second directional short-wave antenna with a second field of view. The first communication node is located within the second field of view.
