TERMINAL APPARATUS, BASE STATION APPARATUS, AND COMMUNICATION METHOD
Included are a radio resource control layer processing unit configured to configure a first control resource set and a second control resource set, based on RRC signaling; a receiver configured to monitor PDCCH candidates in the first control resource set and the second control resource set; and a decoding unit configured to decode the PDCCH candidates, wherein the first control resource set includes OFDM symbols in a first half of the slot, the second control resource set includes OFDM symbols in a latter half of the slot, a first number of the PDCCH candidates are monitored in the first control resource set and a second number of the PDCCH candidates are monitored in the second control resource set in the slot until it is determined that the base station apparatus is transmitting a signal, and a third number of the PDCCH candidates are monitored in the first control resource set in the slot after it is determined that the base station apparatus is transmitting the signal.
1 - 12 . (canceled)
13 . A user equipment (UE) comprising:
radio resource control (RRC) layer process circuitry configured and/or programmed to set one or more control resource sets based on RRC signaling;
reception circuitry configured and/or programmed to monitor one or more physical downlink control channel (PDCCH) candidates in a search space; wherein
in a case that the UE detects a PDCCH, the UE monitors one or more PDCCH candidates in different search space.
14 . The UE according to claim 13 , wherein
each search space is configured of one or more PDCCH candidates in different OFDM symbol(s) in a slot.
15 . A base station device comprising:
radio resource control (RRC) layer process circuitry configured and/or programmed to set one or more control resource sets to a user equipment (UE) using RRC signaling;
transmission circuitry configured and/or programmed to transmit one or more physical downlink control channel (PDCCH); wherein
after the base station transmits a PDCCH using a PDCCH candidate in a search space to the UE, the base station transmits one or more PDCCH using one or more PDCCH candidates in different search space to the UE.
16 . A communication method by using a user equipment (UE), the communication method comprising:
setting one or more control resource sets based on radio resource control (RRC) signaling;
monitoring one or more physical downlink control channel (PDCCH) candidates in a search space; wherein
in a case that the UE detects a PDCCH, the UE monitors one or more PDCCH candidates in different search space.
17 . A communication method by using a base station device, the communication method comprising:
setting one or more control resource sets to a user equipment (UE) using RRC signaling;
transmitting one or more physical downlink control channel (PDCCH); wherein
after the base station transmits a PDCCH using a PDCCH candidate in a search space to the UE, the base station transmits one or more PDCCH using one or more PDCCH candidates in different search space to the UE.
