Abstract
Wireless communications systems and methods related to communicating control information are provided. A method of wireless communication performed by a first sidelink user equipment (UE) may include establishing, with a second sidelink UE, a beamformed link, transmitting, to the second sidelink UE, a periodic discovery and measurement timing (DMTC) configuration via the beamformed link, and transmitting, to the second sidelink UE, a periodic beacon signal based on the DMTC configuration.
Claims30
A method of wireless communication performed by a first sidelink user equipment (UE), the method comprising:
- establishing, with a second sidelink UE, a beamformed link;
- transmitting, to the second sidelink UE, a periodic discovery and measurement timing (DMTC) configuration via the beamformed link;
- transmitting, to the second sidelink UE, a plurality of transport blocks (TBs) via the beamformed link;
- receiving, from the second sidelink UE, a plurality of ACK/NACK responses corresponding to the plurality of TBs;
- incrementing a counter in response to a NACK of the plurality of ACK/NACK responses;
- decreasing the counter in response to an ACK of the plurality of ACK/NACK responses;
- transmitting, to the second sidelink UE, a periodic beacon signal based on the DMTC configuration;
- and
- refraining from transmitting the periodic beacon signal in response to the counter satisfying a threshold.
A method of wireless communication performed by a first sidelink user equipment (UE), the method comprising:
- establishing, with a second sidelink UE, a beamformed link;
- receiving, from the second sidelink UE, a periodic discovery and measurement timing (DMTC) configuration via the beamformed link;
- receiving, from the second sidelink UE, a periodic beacon signal based on the DMTC configuration;
- receiving, from the second sidelink UE, a beacon signal skip indicator;
- and
- refraining from receiving the periodic beacon signal in response to the beacon signal skip indicator.
A first sidelink user equipment (UE) comprising:
- a memory;
- a transceiver;
- and
- at least one processor coupled to the memory and the transceiver, wherein the first sidelink UE is configured to:
- establish, with a second sidelink UE, a beamformed link;
- transmit, to the second sidelink UE, a periodic discovery and measurement timing (DMTC) configuration via the beamformed link;
- transmit, to the second sidelink UE, a plurality of transport blocks (TBs) via the beamformed link;
- receive, from the second sidelink UE, a plurality of ACK/NACK responses corresponding to the plurality of TBs;
- increment a counter in response to a NACK of the plurality of ACK/NACK responses;
- decrease the counter in response to an ACK of the plurality of ACK/NACK responses;
- transmit, to the second sidelink UE, a periodic beacon signal based on the DMTC configuration;
- and
- refrain from transmitting the periodic beacon signal in response to the counter satisfying a threshold.
