Terminal apparatus, base station apparatus, and communication method
A user equipment (UE) includes reception circuitry configured to receive, from a base station, first information indicating a slot format and second information indicating a maximum number of PDCCH repetition, and to monitor, based on the second information, PDCCH repetitions for a first search space set in a first CORESET, and processing circuitry configured to determine, based on the first information, whether to omit monitoring a PDCCH repetition for each PDCCH repetition among the PDCCH repetitions, wherein Downlink Control Information (DCI) is carried by the PDCCH repetition, the DCI schedules a PDSCH, and the DCI includes third information indicating a first number and forth information indicating timing of the PDSCH, and to determine, based on the third information, a first slot in which the last one PDCCH repetition of the PDCCH repetitions with the first number is located, and to determine a starting slot of a PDSCH transmission based on the forth information and the first slot.
1. A user equipment (UE), comprising:
reception circuitry configured to
receive, from a base station, first information indicating a slot format and second information indicating a maximum number of Physical Downlink Control Channel (PDCCH) repetitions, and
monitor, based on the second information, PDCCH repetitions for a first search space set in a first Control Resource Set (CORESET), the PDCCH repetitions carrying Downlink Control Information (DCI), the DCI scheduling a Physical Downlink Shared Channel (PDSCH) transmission; and
processing circuitry configured to
determine, based on the first information, whether to forgo monitoring a PDCCH repetition among the PDCCH repetitions, and
determine, based on third information included in the DCI and a first slot, a starting slot of the PDSCH transmission, the third information indicating timing of the PDSCH transmission, wherein
when the DCI includes fourth information indicating a first number of PDCCH repetitions, the first slot is determined as a slot in which a last PDCCH repetition among the first number of PDCCH repetitions is located, and
when the DCI does not include the fourth information, the first slot is determined as a slot in which the last PDCCH repetition among the maximum number of PDCCH repetitions is located.
2. The UE of claim 1 , wherein
the last PDCCH repetition among the first number of PDCCH repetitions is not received by the UE.
3. A base station, comprising:
transmission circuitry configured to transmit, to a user equipment (UE), first information indicating a slot format and second information indicating a maximum number of Physical Downlink Control Channel (PDCCH) repetitions,
processing circuitry configured to
generate DownlinkControl Information (DCI) wherein the DCI schedules a Physical Downlink Shared Channel (PDSCH) transmission and includes third information indicating timing of the PDSCH transmission,
determine, when the DCI includes fourth information indicating a first number of PDCCH repetitions, that a first slot is a slot in which a last PDCCH repetition among the first number of PDCCH repetitions is located, and determine, when the DCI does not include the fourth information, that the first slot is a slot in which the last PDCCH repetition among the maximum number of PDCCH repetitions is located,
determine a starting slot of the PDSCH transmission based on the third information and the first slot, and
determine, based on the first information, whether to forgo transmitting a PDCCH repetition among PDCCH repetitions; and
the transmission circuitry is further configured to repeatedly transmit, to the UE, the PDCCH repetitions fora first search space set in a first Control Resource Set (CORESET), wherein the PDCCH re petitions carry the DCI.
4. The base station of claim 3 , wherein
the last PDCCH repetition among the first number of PDCCH repetitions is not transmitted by the base station.
5. A method performed by a user equipment (UE), the method comprising:
receiving, from a base station, first information indicating a slot format and second information indicating a maximum number of Physical Downlink Control Channel (PDCCH) repetitions;
monitoring, based on the second information, PDCCH repetitions for a first search space set in a first Control Resource Set (CORESET), the PDCCH repetitions carrying Downlink Control Information (DCI), the DCI scheduling a Physical Downlink Shared Channel (PDSCH) transmission;
determining, based on the first information, whether to forgo monitoring a PDCCH repetition among the PDCCH repetitions; and
determining, based on third information included in the DCI and a first slot, a starting slot of the PDSCH transmission, the third information indicating timing of the PDSCH transmission, wherein
in response to the DCI including fourth information indicating a first number of PDCCH repetitions, the first slot is determined as a slot in which a last PDCCH repetition among the first number of PDCCH repetitions is located, and
in response to the DCI not including the fourth information, the first slot is determined as a slot in which the last PDCCH repetition among the maximum number of PDCCH repetitions is located.
6. The method of claim 5 , wherein
the last PDCCH repetition among the first number of PDCCH repetitions is not received by the UE.
