Terminal apparatus, base station apparatus, and communication method
A terminal apparatus including a higher layer configured to configure a configuration related to a search space set and a configuration related to a PDCCH, and a receiver configured to monitor the PDCCH based on the search space set. In a case that one or multiple group indexes are allocated to the search space set and that neither monitoring of the PDCCH corresponding to the search space set with a group index of 0 among the one or multiple group indexes nor monitoring of the PDCCH corresponding to the search space set with a group index of 1 among the one or multiple group indexes is performed, the receiver initiates monitoring of the PDCCH corresponding to the search space set with a group index of 0 among the one or multiple group indexes.
1 . A terminal apparatus comprising:
higher layer processing circuitry configured to be provided with a searchSpaceGroupIdList-r16 associated with a group index for each search space set per BandWidth Part (BWP); and
receiving circuitry configured to monitor a physical downlink control channel (PDCCH) based on each search space set, wherein
the searchSpaceGroupIdList-r16 comprises information for setting the group index for each search space set according to a value given by a searchSpaceSwitchingTimer-r16, and
the receiving circuitry monitors the PDCCH for a search space set per BWP corresponding to a group index 0 in a case that the searchSpaceGroupIdList-r16 is provided.
2 . A base station apparatus for communicating with a terminal apparatus, the base station apparatus comprising:
higher layer processing circuitry configured to transmit a searchSpaceGroupIdList-r16 associated with a group index for each search space set per BandWidth Part (BWP); and
transmission circuitry configured to transmit a physical downlink control channel (PDCCH) based on each search space set, wherein
the searchSpaceGroupIdList-r16 comprises information for setting the group index for each search space set according to a value given by a searchSpaceSwitchingTimer-r16, and
the transmission circuitry transmits the PDCCH for a search space set per BWP corresponding to a group index 0 in a case that the searchSpaceGroupIdList-r16 is transmitted.
3 . A communication method comprising:
being provided with a searchSpaceGroupIdList-r16 associated with a group index for each search space set per BandWidth Part (BWP); and
monitoring a physical downlink control channel (PDCCH) based on each search space set, wherein
the searchSpaceGroupIdList-r16 comprises information for setting the group index for each search space set according to a value given by a searchSpaceSwitchingTimer-r16, and
the monitoring of the PDCCH comprises:
monitoring the PDCCH for a search space set per BWP corresponding to a group index 0 in a case that the searchSpaceGroupIdList-r16 is provided.
