For example, a first node may communicate with a second node, e.g., via a backhaul link, one or more messages including a restriction recommendation and/or a restriction setting, for example, a precoding restriction, a Relative Narrowband TX Power indication (RNTP) setting, and/or a Relative Wideband Transmit Power (RWTP) setting.

Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive control signaling which indicates a resource block indicating a number of reference signal tones and data tones in an uplink transmission. In some cases, the UE may determine a first transmission power for the reference signal tones, and a second transmission power for the data tones that is different from the first transmission power. In some other cases, the UE may identify a frequency allocation for the resource block which allocates a same frequency bandwidth for the reference signal tones and the data tones, and the UE may determine a same transmission power for the reference signal tones and the data tones based on the frequency allocation. Based on the determination of transmission powers, the UE may transmit the reference signal tones and the data tones to a base station.

A method for operating a user equipment (UE) is provided. The method comprises transmitting, to a base station (BS), UE capability information including a full power transmission capability of the UE, wherein the full power transmission capability of the UE includes a parameter S to indicate a group of full power transmit precoding matrix indicators (TPMIs); receiving, from the BS, configuration information for a physical uplink shared channel (PUSCH) transmission, wherein the configuration information includes a TPMI; determining the PUSCH transmission; determining a power level for the PUSCH transmission; and transmitting, to the BS, the PUSCH transmission with the determined power level, wherein the power level corresponds to full power based on the TPMI being included in the group of full power TPMIs, and wherein the TPMI indicates a precoding matrix and a number of layers for the PUSCH transmission.

Apparatuses, methods, and computer readable media for setting parameters for joint overlapping basic service set packet detect level and transmit power. An apparatus is disclosed comprising processing circuitry configured to: determine an overlapping basic service set (OBSS) power detect (PD)(OBSS-PD) and a transmit power (TXP) based on first parameters, and if the wireless device has not received a frame from an OBSS master station that does not belong to a same management domain as the wireless device, determine the OBSS-PD and TXP based on second parameters. The second parameters may permit the wireless device to set the OBSS-PD to a higher value without lowering the TXP. The first parameters require that OBSS-PD and TXP be determined based on a minimum OBSS-PD and a maximum TXP, and require the OBSS-PD to be lowered if the TX power is raised.

The present invention is designed to provide a radio communication system which can control uplink transmission power adequately even in an HetNet environment.
