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 signal transmission method includes: transmitting, by a network device, priority information of a plurality of uplink signals to a terminal device, wherein the priority information of the plurality of uplink signals is used by the terminal device to determine an effective transmission power of the plurality of uplink signals; and receiving, by the network device, the plurality of uplink signal in a same frequency domain resource set transmitted by the terminal device according to the effective transmission power.

The present invention relates to an electronic device, comprising a modem which: when simultaneously connected to a master cell group according to a first communication mode and a secondary cell group according to a second communication mode, if a transmission power of a first uplink signal transmitted to the master cell group is greater than or equal to a preset maximum transmission power, controls a plurality of power amplification units such that transmission of a second uplink signal to be transmitted to the secondary cell group is deferred; and, if the transmission of the second uplink signal remains deferred for a preset time period, stops the transmission of the first uplink signal for a certain period of time and transmits the second uplink signal, thereby maintaining connectivity to the secondary cell group even when the transmission of the second uplink signal is deferred.

Presented herein are techniques to shield transmissions from being received and the information contained in them recovered by unwanted devices. Multi-user multiple-input multiple-output (MU-MIMO) techniques are employed, and in particular the spatial dimension aspects of those techniques. Shield nodes are controlled to transmit in a way to obscure the downlink streams transmitted by a wireless access point that are intended for a particular client device to anything outside of the shielded area, and also to obscure uplink streams from one or more client devices to the wireless access point to anything outside of the shielded area but allowing the uplink streams to be well received by the wireless access point.

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may transmit, to a network node, a first uplink transmission using a first transmit power that is based at least in part on: a first power level associated with the first uplink transmission, and a power scaling factor based at least in part on a power offset. The UE may transmit, to the network node, a second uplink transmission, at least partially overlapping in time with the first uplink transmission, using a second transmit power that is based at least in part on: a second power level associated with the second uplink transmission, a maximum available transmit power, and the first transmit power. Numerous other aspects are described.

Methods, systems, and devices for wireless communications are described. A user equipment (UE) may identify a set of carriers within a frequency band for communicating with a base station via either carrier aggregation or dual connectivity. The UE may determine that a first parameter for communications over a first carrier exceeds a threshold with respect to corresponding parameters of other carriers, the first parameter being either a downlink reception parameter or an uplink transmission parameter. The UE may refrain from communicating over the first carrier based at least in part on the first parameter exceeding the threshold.

The implementations of the present disclosure provide a wireless communication method and device, being able to determine, with reference to the transmission power of one uplink signal, the transmission power of another signal as required in a reasonable manner, and directly schedule the fixed transmission power without the need of a network device, thereby improving the communication performance. The method comprises: a terminal device determining a reference uplink signal of a target uplink signal; the terminal device determining the transmission power of the target uplink signal according to the transmission power of the reference uplink signal; and the terminal device transmitting the target uplink signal by using the determined transmission power.

This disclosure provides systems, methods, and devices for wireless communication that support controlling transmit power of one or more groups of user equipment (UE) sidelinks using a single sidelink control transmission of group transmit power control (TPC) information. A first UE may transmit group TPC information to one or more groups of UEs, such as by including the group TPC information in sidelink control information (SCI). The group TPC information may include a group TPC indicator and one or more TPC messages for providing one or more group TPC commands with respect to groups of sidelinks. The group TPC commands may provide for power control with respect to a respective group of UEs for one or more channels. Other aspects and features are also claimed and described.
