Abstract
Aspects of the present disclosure provide apparatus, methods, processing systems, and computer readable mediums for determining timing advances (TAs) for use in sidelink (SL) communications. A method that may be performed by a transceiver (TX) user equipment (UE) includes applying a first TA when transmitting at least a first SL transmission to a receiver (RX) UE and applying a second TA when transmitting at least a second SL transmission to the RX UE.
Claims24
A method of wireless communications by a transmitter (TX) user equipment (UE), comprising:
- applying a first timing advance (TA) when transmitting at least a first sidelink (SL) transmission to a receiver (RX) UE, wherein the first SL transmission comprises a first transmission of a first transport block (TB);
- and
- applying a second TA when transmitting at least a second SL transmission to the RX UE, wherein:
- the second SL transmission comprises a retransmission of the first TB;
- and
- the second TA is based on a gap duration between an end of the first SL transmission and a beginning of the second SL transmission.
A method of wireless communications by a receiver (RX) user equipment (UE), comprising:
- obtaining, from a transmitter (TX) UE, an indication of a timing advance (TA) in a first sidelink (SL) transmission, wherein the first SL transmission comprises a first transmission of a first transport block (TB);
- and
- applying the TA when receiving at least a second SL transmission from the TX UE, wherein:
- the second SL transmission comprises a retransmission of the first TB;
- and
- the TA is based on a gap duration between an end of the first SL transmission and a beginning of the second SL transmission.
A user equipment (UE) configured for wireless communications, comprising:
- a memory comprising processor-executable instructions;
- and
- a processor configured to execute the processor-executable instructions and cause the UE to:
- apply a first timing advance (TA) when transmitting, via at least one antenna, at least a first sidelink (SL) transmission to a receiver (RX) UE, wherein the first SL transmission comprises a first transmission of a first transport block (TB);
- and
- apply a second TA when transmitting, via the at least one antenna, at least a second SL transmission to the RX UE, wherein:
- the second SL transmission comprises a retransmission of the first TB;
- and
- the second TA is based on a gap duration between an end of the first SL transmission and a beginning of the second SL transmission.
A user equipment (UE) configured for wireless communications, comprising:
- a memory comprising processor-executable instructions;
- and
- a processor configured to execute the processor-executable instructions and cause the UE to:
- receive, from a transmitter (TX) UE, an indication of a timing advance (TA), in a first sidelink (SL) transmission, wherein the first SL transmission comprises a first transmission of a first transport block (TB);
- and
- apply the TA when receiving at least a second SL transmission from the TX UE, wherein:
- the second SL transmission comprises a retransmission of the first TB;
- and
- and the TA is based on a gap duration between an end of the first SL transmission and a beginning of a second SL transmission.
