Abstract
An operation method of a first UE in a communication system is provided. The method includes transmitting to a second UE a an SL-SSB in an omni-directional scheme and transmitting the SL-SSB in a beamforming scheme when a response message for the SL-SSB transmitted in the omni-directional scheme is not received from the second UE. Additionally, sidelink communication with the second UE according to the beamforming scheme when a response message for the SL-SSB transmitted in the beamforming scheme is received from the second UE.
Claims15
A method of a first user equipment (UE), comprising:
- transmitting a synchronization signal block (SSB) through each of a plurality of beams of the first UE;
- receiving information of a first beam in which a first SSB is transmitted among the plurality of beams from a second UE;
- determining one or more beams except for the first beam among the plurality of beams as candidate beam(s);
- configuring the candidate beam(s) with the second UE;
- and
- performing communications with the second UE using the first beam.
A method of a second user equipment (UE), comprising:
- receiving a synchronization signal block (SSB) through each of a plurality of beams from a first UE;
- determining a first SSB among a plurality of SSBs received through the plurality of beams based on reception quality;
- transmitting information of a first beam in which a first SSB is received among the plurality of beams to the first UE;
- receiving configuration information of candidate beam(s) from the first UE;
- and
- performing communications with the first UE using the first beam,
- wherein the candidate beam(s) is one or more beams except for the first beam among the plurality of beams.
A first user equipment (UE), comprising:
- a processor;
- and
- a memory storing one or more commands executed by the processor,
- wherein the one or more commands are executed to:
- transmit a synchronization signal block (SSB) through each of a plurality of beams of the first UE;
- receive information of a first beam in which a first SSB is transmitted among the plurality of beams from a second UE;
- determine one or more beams except for the first beam among the plurality of beams as candidate beam(s);
- configure the candidate beam(s) with the second UE;
- and
- perform communications with the second UE using the first beam.
