Abstract
A method of wireless communications by a transmitting sidelink user equipment (UE) includes transmitting a sidelink synchronization signal (SL-SS) within a sidelink synchronization signal block (S-SSB). The SL-SS has an SL-SS pattern with a reduced number of physical sidelink broadcast channel (PSBCH) symbols, which may be zero PSBCH symbols. The method also includes receiving transmission in accordance with the SL-SS. The SL-SS may be transmitted at a time and/or frequency different from a legacy SL-SS.
Claims28
A method of wireless communications by a transmitting sidelink user equipment (UE), comprising:
- transmitting a sidelink synchronization signal (SL-SS) within a sidelink synchronization signal block (S-SSB), the S-SSB having an SL-SS pattern without physical sidelink broadcast channel (PSBCH) symbols and with only at least one sidelink primary synchronization signal (S-PSS) and/or at least one sidelink secondary synchronization signal (S-SSS), wherein the SL-SS pattern reduces overhead for the S-SSB;
- and
- receiving transmissions in accordance with the SL-SS.
An apparatus for wireless communications at a user equipment (UE), comprising:
- a processor;
- memory coupled with the processor;
- and
- instructions stored in the memory and operable, when executed by the processor, to cause the apparatus:
- to transmit a sidelink synchronization signal (SL-SS) within a sidelink
- synchronization signal block (S-SSB), the S-SSB having an SL-SS pattern
- without physical sidelink broadcast channel (PSBCH) symbols and with only at least one sidelink primary synchronization signal (S-PSS) and/or at least one sidelink secondary synchronization signal (S-SSS), wherein the SL-SS pattern reduces overhead for the S-SSB;
- and
- to receive transmissions in accordance with the SL-SS.
An apparatus for wireless communications by a transmitting sidelink user equipment (UE), comprising:
- means for transmitting a sidelink synchronization signal (SL-SS) within a sidelink synchronization signal block (S-SSB), the S-SSB having an SL-SS pattern without physical sidelink broadcast channel (PSBCH) symbols and with only at least one sidelink primary synchronization signal (S-PSS) and/or at least one sidelink secondary synchronization signal (S-SSS), wherein the SL-SS pattern reduces overhead for the S-SSB;
- and
- means for receiving transmissions in accordance with the SL-SS.
