User equipments, base stations, and methods
A method for a user equipment (UE) which communicates with a base station is described. The method may comprise acquiring radio resource control (RRC) configuration information. The RRC configuration information may indicate one or more entries, each of the entries specifying a slot format. The method may also comprise receiving a physical signal and a physical downlink control channel (PDCCH) with a downlink control (DCI) format. The DCI format may include a first information field and a second information field. The first information field may indicate an entry out of the entries. The second information field may indicates channel occupancy status of all channel access bandwidths in a bandwidth part.
1. A user equipment (UE) which communicates with a base station, the UE comprising:
higher layer processing circuitry configured to acquire radio resource control (RRC) configuration information, the RRC configuration information indicating one or more entries, each of the entries specifying a slot format; and
receiving circuitry configured to receive a physical downlink control channel (PDCCH) with a down link control information (DCI) format;
wherein
the DCI format includes a first information field and a second information field,
the first information field indicates an entry out of the entries, and the second information field is a bitmap indicating channel occupancy status of a plurality of channel access bandwidths.
2. The UE according to the claim 1 , wherein
the slot format is able to indicate that a symbol is outside of channel occupancy.
3. A base station which communicates with a user equipment (UE), the base station comprising:
higher layer processing circuitry configured to send radio resource control (RRC) configuration information, the RRC configuration information indicating one or more entries, each of the entries specifying a slot format; and
transmitting circuitry configured to transmit a physical downlink control channel (PDCCH) with a down link control information (DCI) format;
wherein
the DCI format includes a first information field and a second information field,
the first information field indicates an entry out of the entries, and the second information field is a bitmap indicating channel occupancy status of a plurality of channel access bandwidths.
4. The base station according to the claim 3 , wherein
the slot format is able to indicate that a symbol is outside of channel occupancy.
5. A method for a user equipment (UE) which communicates with a base station, the method comprising:
acquiring radio resource control (RRC) configuration information, the RRC configuration information indicating one or more entries, each of the entries specifying a slot format; and
receiving a physical downlink control channel (PDCCH) with a down link control information (DCI) format;
wherein
the DCI format includes a first information field and a second information field,
the first information field indicates an entry out of the entries, and the second information field is a bitmap indicating channel occupancy status of a plurality of channel access bandwidths.
6. A method for a base station which communicates with a user equipment (UE), the method comprising:
sending radio resource control (RRC) configuration information, the RRC configuration information indicating one or more entries, each of the entries specifying a slot format; and
transmitting a physical downlink control channel (PDCCH) with a down link control information (DCI) format;
wherein
the DCI format includes a first information field and a second information field,
the first information field indicates an entry out of the entries, and the second information field is a bitmap indicating channel occupancy status of a plurality of channel access bandwidths.
7. The UE according to claim 1 , wherein
the channel access bandwidths are derived by second RRC configuration information.
8. The base station according to claim 3 , wherein
the channel access bandwidths are derived by second RRC configuration information.
