Abstract
A method of a UE may comprise: receiving beam DTX group configuration information from a base station through a first beam or a second beam; monitoring reception of first beam DTX group control information indicating beam DTX activation for at least one beam of the first beam or the second beam based on the beam DTX group configuration information; determining whether beam DTX activation for the first beam is indicated based on reception of the first beam DTX group control information; and performing discontinuous reception of DL wireless signals from the base station through the first beam, based on the beam DTX activation being indicated for the first beam.
Claims20
A method of a user equipment (UE), comprising:
- receiving beam discontinuous transmission (DTX) group configuration information from a base station through a first beam or a second beam;
- monitoring reception of first beam DTX group control information indicating beam DTX activation for at least one beam of the first beam or the second beam based on the beam DTX group configuration information;
- determining whether beam DTX activation for the first beam is indicated based on reception of the first beam DTX group control information;
- and
- performing discontinuous reception of downlink (DL) wireless signals from the base station through the first beam, based on the beam DTX activation being indicated for the first beam,
- wherein the DL wireless signals include at least one of:
- a first physical downlink control channel (PDCCH), a first physical downlink shared channel (PDSCH), a reference signal (RS), or a synchronization signal (SS).
A method of a base station, comprising:
- transmitting beam discontinuous transmission (DTX) group configuration information for a plurality of beams to a user equipment (UE);
- based on beam DTX being required for one or more beam groups, transmitting, to the UE, first beam DTX group control information for controlling beam DTX activation based on the beam DTX group configuration information, each beam group including one or more beams among the plurality of beams;
- and
- performing discontinuous transmission of downlink (DL) wireless signals through each beam for which beam DTX is indicated by the first beam DTX group control information, based on the beam DTX group configuration information,
- wherein the beam DTX group configuration information includes at least one of:
- beam group information for each of the one or more beam groups, a common beam group-radio network temporary identifier (RNTI) for all beam groups, a beam group-RNTI for each of the one or more beam groups, or beam DTX time domain information, and
- wherein the DL wireless signals include at least one of:
- a first physical downlink control channel (PDCCH), a first physical downlink shared channel (PDSCH), a reference signal (RS), or a synchronization signal (SS).
A user equipment (UE) comprising at least one processor, wherein the at least one processor causes the UE to perform:
- receiving beam discontinuous transmission (DTX) group configuration information from a base station through a first beam or a second beam;
- monitoring reception of first beam DTX group control information indicating beam DTX activation for at least one beam of the first beam or the second beam based on the beam DTX group configuration information;
- determining whether beam DTX activation for the first beam is indicated based on reception of the first beam DTX group control information;
- and
- performing discontinuous reception of downlink (DL) wireless signals from the base station through the first beam, based on the beam DTX activation being indicated for the first beam,
- wherein the DL wireless signals include at least one of:
- a first physical downlink control channel (PDCCH), a first physical downlink shared channel (PDSCH), a reference signal (RS), or a synchronization signal (SS).
