Abstract
Aspects of the present disclosure provide apparatus, methods, processing systems, and computer readable mediums for channel and/or resource selection for sidelink communications. In some cases, a transmitter user equipment UE may transmit, on a sidelink channel used for communicating with other UEs, a control message indicating at least one range, monitor for feedback associated with detection of the control message by one or more other UEs within the indicated range, and transmit data if the feedback indicates at least that the sidelink channel is free.
Claims30
A method for wireless communications by a transmitter user equipment (UE), comprising:
- transmitting, on a sidelink channel used for communicating with other UEs, a control message indicating at least one range;
- monitoring for feedback associated with detection of the control message by one or more other UEs within the indicated range;
- and
- transmitting data if the feedback indicates at least that the sidelink channel is free.
A method for wireless communications by a receiver user equipment (UE), comprising:
- detecting, on a sidelink channel used for communicating with other UEs, a control message from a transmitter UE indicating at least one range;
- determining whether the receiver UE is within the at least one range;
- and
- transmitting, based on the determination, feedback to the transmitter UE indicating whether the sidelink channel is free.
A transmitter user equipment (UE), comprising:
- a transmitter configured to transmit, on a sidelink channel used for communicating with other UEs, a control message indicating at least one range;
- and
- a processing system configured to monitor for feedback associated with detection of the control message by one or more other UEs within the indicated range, wherein:
- the transmitter is further configured to transmit data if the feedback indicates at least that the sidelink channel is free.
A receiver user equipment (UE), comprising:
- a processing system configured to:
- detect, on a sidelink channel used for communicating with other UEs, a control message from a transmitter UE indicating at least one range;
- and
- determine whether the receiver UE is within the at least one range;
- and
- a transmitter configured to transmit, based on the determination, feedback to the transmitter UE indicating whether the sidelink channel is free.
