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 sidelink communication. The UE may generate a transmit power control command based at least in part on a measurement of the sidelink communication. The UE may transmit, via a sidelink feedback channel, the transmit power control command to control a transmit power, for another sidelink communication, of the source UE. Numerous other aspects are provided.

Disclosed are data transmission method and apparatus using path diversity. The data transmission method using path diversity may include steps of: (a) calculating a delay robustness value representing path diversity for a routing path including at least one relay node; (b) determining a trade-off relationship between the delay robustness value and power consumption; (c) determining the power consumption and a routing path based on the trade-off relationship; and (d) transmitting data to a destination node through the routing path according to the power consumption.

This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for managing transmit power control. In one aspect, a wireless device may receive a message including a path loss value and may transmit a signal to a UL Rx point using an uplink transmit power associated with the received path loss value. In another aspect, a wireless device may receive a reference signal, and a message including an offset value, and may transmit a signal to a UL Rx point using an uplink transmit power including a downlink path loss value associated with the reference signal minus the offset value. In another aspect, a base station may obtain a power measurement of a signal from a wireless device and may send to the wireless device a path loss value associated with the received power measurement, or an offset value associated with the received power measurement.

The disclosure provides systems, devices, and methods for distributed relay multiple-in multiple-out (DR-MIMO) communications. The system can have a master transmit node that transmits a message to a master receive node via one or more relay nodes. The relay nodes can each relay a portion of the message, performing a time or frequency shift along with the relay. The multiple relay nodes can function as a distributed antenna array for one or both of the master transmit node and the master receive node, forming a transmit group and/or a receive group. The transmit group and the receive group can thus provide MIMO capabilities to the master transmit node and the master receive node. The master transmit node can transmit multiple spatial streams through distributed relay nodes. The master receive node can receive multiple data streams from distributed relay nodes and perform MIMO detection.

A wire device receives: configuration parameters of: a primary cell with a primary physical uplink control channel (PUCCH); and a secondary cell with a secondary PUCCH; a transmit power control (TPC) radio network temporary identifier (RNTI); a primary TPC index of the primary PUCCH; and a secondary TPC index of the secondary PUCCH. The wireless device receives a downlink control information (DCI) associated with the TPC RNTI. The secondary TPC index identifies a TPC command in an array of TPC commands in the DCI. The wireless device adjusts a transmission power of the secondary PUCCH based on the TPC command.
