Techniques for automatic gain control in sidelink systems

An apparatus for wireless communication at a second user equipment (UE), comprising:

• a processing system that includes processor circuitry and memory circuitry that stores code, the processing system configured to cause the second UE to:
• receive, from a scheduling device, a control message indicating a duration of time, wherein the control message configures one or more UEs to each use a same transmit power for sidelink signaling that occurs during the duration of time;
• receive, from a first UE of the one or more UEs, a training sidelink transmission transmitted at a transmit power on a resource;
• determine an automatic gain control configuration based at least in part on receiving the training sidelink transmission;
• and
• receive, from the first UE, one or more sidelink transmissions via resources within the duration of time based at least in part on the automatic gain control configuration and the control message that configures the one or more UEs to use the same transmit power for the sidelink signaling that occurs during the duration of time.

An apparatus for wireless communication at a scheduling device, comprising:

• a processing system that includes processor circuitry and memory circuitry that stores code, the processing system configured to cause the scheduling device to:
• transmit, to at least a first user equipment (UE), a control message indicating a duration of time, wherein the control message configures the first UE to use a same transmit power for instances of sdelink signaling that occur during the duration of time, wherein the same transmit power is a transmit power used by the first UE to transmit on a resource;
• and
• transmit a configuration to the first UE scheduling the first UE with resources for one or more sidelink transmissions to a second UE using the same transmit power, wherein the resources for the one or more sidelink transmissions are within the duration of time.

A method for wireless communications at a first user equipment (UE), comprising:

• receive, from a scheduling device, a control message indicating a duration of time, wherein the control message configures the first UE to use a same transmit power for instances of sidelink signaling that occur during the duration of time;
• transmit, to a second UE and based at least in part on the control message, a training sidelink transmission using a transmit power on a resource;
• and
• transmit, to the second UE, one or more sidelink transmissions using the transmit power via resources within the duration of time based at least in part on the control message that configures the first UE to use the same transmit power for the sidelink signaling that occurs during the duration of time.
