Abstract: Aspects of the disclosure relate to downlink (DL) transmissions using various powers and assigning frequency resources based on the powers. An example base station may transmit, to a first user equipment (UE), an indication of a first transmit (Tx) power for one or more first DL transmissions to a first group of a plurality of groups. The first group may include the first UE. The first Tx power may have a first power level different from a second power level of a second Tx power for one or more second DL transmissions to a second group of the plurality of groups. Then, the base station may transmit, to the first UE, a first DL transmission of the one or more first DL transmissions using the first Tx power. Other aspects, embodiments, and features are also claimed and described.

Abstract: There is provided mechanisms for estimating sidelink pathloss value of a sidelink between a first UE and a second UE. The method is performed by the first UE. The method comprises obtaining an access link pathloss value of an access link between the first UE and a radio access network node serving the first UE. The method comprises obtaining a first distance value of distance between the first UE and the radio access network node. The method comprises obtaining a second distance value of distance between the first UE and the second UE. The method comprises estimating the sidelink pathloss value as a function of the first distance value, the access link pathloss value, and the second distance value.

Abstract: An end point (EP) device may communicate with multiple gateways via wireless signals, e.g. wireless broadcast signals. An EP device is controlled, under the direction of a control server, e.g., an application server, to communicate via a single gateway. The control server associates the EP device with a single target gateway and/or uses EP transmission power control training iterations to reduce the EP transmission power level until the EP device is only able to successfully communicate its wireless signals to a single gateway.

Abstract: A method includes instructing, by a WiFi access node, a first device to communicate using an uplink frequency band with a first uplink power. The method also includes instructing, by the WiFi access node, a second device to communicate using the uplink frequency band with a second uplink power different from the first uplink power.

Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) that is configured with two sets of power control parameters may be signaled (e.g., via downlink control information (DCI)) as to which set of parameters to use for determining the transmission power on a sidelink channel. The UE may determine a transmit power for a sidelink message based on the indication included in the DCI. The base station may transmit the indication based on whether uplink or downlink communications are scheduled on resources that may overlap with resources used for transmission of the sidelink message.

Abstract: There is provided mechanisms for context-triggered power control of a sidelink between a first UE and a second UE. A method is performed by the first UE. The method comprises controlling transmission power of the sidelink depending on transmission context in which transmission on the sidelink is triggered.
