Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
The invention claimed is: 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.
