Abstract
A terminal apparatus for receiving a Physical Downlink Control Channel (PDCCH) is provided. The terminal apparatus includes: a radio resource control layer processing unit configured to configure a control resource set based on Radio Resource control (RRC) signaling; a receiver configured to monitor a plurality of PDCCH candidates in the control resource set; and a decoding unit configured to decode a PDCCH candidate of the plurality of PDCCH candidates where the control resource set is configured for a Listen-Before-Talk subband (LBT subband) in a bandwidth part (BWP).
Claims12
A terminal apparatus for performing a listen-before-talk (LBT) procedure in a bandwidth part (BWP), the terminal apparatus comprising:
- one or more non-transitory computer-readable media having computer-executable instructions embodied thereon;
- and
- at least one processor coupled to the one or more non-transitory computer-readable media, the at least one processor being configured to execute the computer-executable instructions to:
- configure a plurality of control resource sets based on radio resource control (RRC) signaling, each of the plurality of control resource sets being a set of control channels to be monitored by the terminal apparatus;
- monitor a plurality of physical downlink control channels (PDCCHs) in the plurality of control resource sets;
- and
- decode the plurality of PDCCHs, wherein:
- each of the plurality of control resource sets is configured for a corresponding one of a plurality of LBT subbands in a bandwidth part (BWP), and
- each of the plurality of LBT subbands is a specific subband of the BWP.
A communication method used in a terminal apparatus for performing a listen-before-talk (LBT) procedure in a bandwidth part (BWP), the communication method comprising:
- configuring a plurality of control resource sets based on radio resource control (RRC) signaling, each of the plurality of control resource sets being a set of control channels to be monitored by the terminal apparatus;
- monitoring a plurality of physical downlink control channels (PDCCHs) in the plurality of control resource sets;
- and
- decoding the plurality of PDCCHs, wherein:
- each of the plurality of control resource sets is configured for a corresponding one of a plurality of LBT subbands in a bandwidth part (BWP), and
- each of the plurality of LBT subbands is a specific subband of the BWP.
A base station apparatus for configuring a listen-before-talk (LBT) procedure in a bandwidth part (BWP), the base station apparatus comprising:
- one or more non-transitory computer-readable media having computer-executable instructions embodied thereon;
- and
- at least one processor coupled to the one or more non-transitory computer-readable media, the at least one processor being configured to execute the computer-executable instructions to:
- configure a plurality of control resource sets for a terminal apparatus, each of the plurality of control resource sets being a set of control channels to be monitored by the terminal apparatus;
- and
- transmit a plurality of physical downlink control channels (PDCCHs) in the plurality of control resource sets, wherein:
- each of the plurality of control resource sets is configured for a corresponding one of a plurality of LBT subbands in a bandwidth part (BWP) for the terminal apparatus to perform the LBT procedure, and
- each of the plurality of LBT subbands is a specific subband of the BWP.
A communication method used in a base station apparatus for configuring a listen-before-talk (LBT) procedure in a bandwidth part (BWP), the communication method comprising:
- configuring a plurality of control resource sets for a terminal apparatus, each of the plurality of control resource sets being a set of control channels to be monitored by the terminal apparatus;
- and
- transmitting a plurality of physical downlink control channels (PDCCHs) in the plurality of control resource sets, wherein:
- each of the plurality of control resource sets is configured for a corresponding one of a plurality of LBT subbands in a bandwidth part (BWP) for the terminal apparatus to perform the LBT procedure, and
- each of the plurality of LBT subbands is a specific subband of the BWP.
