Method for transmitting and receiving PSSCH in wireless communication system, and device therefor
The present disclosure proposes a method for transmitting and receiving a PSSCH in a wireless communication system, and a device therefor. The method, carried by first user equipment, may comprise the steps of: determining an SL resource on the basis of a set of preferred resources or a set of non-preferred resources related to second user equipment; transmitting, on the basis of the SL resource, a PSCCH including SCI to the second user equipment; and transmitting, on the basis of the SCI, the PSSCH to the second user equipment.
1 . A method comprising:
determining, by a first user equipment (UE), a sidelink (SL) resource based on a set of preferred resources or a set of non-preferred resources related to a second UE;
transmitting a sidelink control channel including sidelink control information (SCI) to the second UE based on the SL resource; and
transmitting a sidelink shared channel to the second UE based on the SCI,
wherein the set of preferred resources or the set of non-preferred resources is i) included in a slot set related to SL transmission in time domain, and ii) included in an SL bandwidth part (BWP) in frequency domain,
wherein the slot set related to the SL transmission corresponds to a set of slots capable of the SL transmission, determined based on i) resource pool configuration including information for reserved slots and ii) presence of synchronization signal block (SSB), and
wherein the set of preferred resources or the set of non-preferred resources is configured based on a resource block (RB) of a lowest index included in the SL BWP, or to at least on subchannel among a plurality of subchannels included in the SL BWP.
2 . The method of claim 1 , further comprising:
receiving assistance information including information for the set of preferred resources or the set of non-preferred resources from the second UE.
3 . The method of claim 2 , further comprising:
requesting the assistance information to the second UE based on availability of the assistance information by the first UE, or based on the first UE operating in sidelink resource allocation mode 2.
4 . A first user equipment (UE) comprising:
at least one transceiver;
at least one processor; and
at least one memory operably connected to the at least one processor, and storing instructions for performing operations based on being executed by the at least one processor,
wherein the operations include:
determining a sidelink (SL) resource based on a set of preferred resources or a set of non-preferred resources related to a second UE;
transmitting a sidelink control channel including sidelink control information (SCI) to the second UE based on the SL resource; and
transmitting a sidelink shared channel to the second UE based on the SCI,
wherein the set of preferred resources or the set of non-preferred resources is i) included in a slot set related to SL transmission in time domain, and ii) included in an SL bandwidth part (BWP) in frequency domain,
wherein the slot set related to the SL transmission corresponds to a set of slots capable of the SL transmission, determined based on i) resource pool configuration including information for reserved slots and ii) presence of synchronization signal block (SSB), and
wherein the set of preferred resources or the set of non-preferred resources is configured based on a resource block (RB) of a lowest index included in the SL BWP, or to at least on subchannel among a plurality of subchannels included in the SL BWP.
5 . The first UE of claim 4 , further comprising:
receiving assistance information including information for the set of preferred resources or the set of non-preferred resources from the second UE.
6 . A method comprising:
receiving a sidelink control channel including sidelink control information (SCI) from a first user equipment (UE) based on sidelink (SL) resource; and
receiving the sidelink control channel from the first UE based on the SCI,
wherein the SL resource is determined based on a set of preferred resources or a set of non-preferred resources related to a second UE,
wherein the set of preferred resources or the set of non-preferred resources is i) included in a slot set related to SL transmission in time domain, and ii) included in an SL bandwidth part (BWP) in frequency domain,
wherein the slot set related to the SL transmission corresponds to a set of slots capable of the SL transmission, determined based on i) resource pool configuration including information for reserved slots and ii) presence of synchronization signal block (SSB), and
wherein the set of preferred resources or the set of non-preferred resources is configured based on a resource block (RB) of a lowest index included in the SL BWP or to at least one subchannel among a plurality of subchannels included in the SL BWP.
7 . The method of claim 6 , further comprising:
transmitting, by the second UE, assistance information including information for the set of preferred resources or the set of non-preferred resources to the first UE.
8 . The method of claim 7 , further comprising:
receiving a request for the assistance information from the first UE based on availability of the assistance information by the first UE, or based on the first UE operating in sidelink resource allocation mode 2.
