Abstract

Claims (34)

1 . A method of communication of a user equipment (UE), comprising:

being configured, by a base station, to receive a downlink transmission on a set of symbols in a slot and a set of resource blocks (RBs); and

being configured to detect a downlink control information (DCI) format, wherein the DCI format comprises at least one of the followings:

a first information that is used to indicate one or more slot formats;

a second information that is used to indicate the channel occupancy duration of the base station; or

a third information that is used to indicate one or more RB sets availability for reception; and

determining whether to receive or cancel reception of the configured downlink transmission on the set of symbols in the slot and on the set of RBs according to a detection result of the DCI format, wherein,

in a case that the DCI format comprises at least one of the first information, the second information, and the third information, and the UE does not detect the DCI format providing a corresponding indication for the configured downlink transmission, the UE cancels the reception of the configured downlink transmission on the set of symbols in the slot and on the set of RBs; and

in a case that the DCI format does not comprise at least one of the first information, the second information, and the third information, and the UE does not detect the DCI format providing a corresponding indication for the configured downlink transmission, the UE receives the configured downlink transmission.

2 . The method of claim 1 , wherein the set of symbols in the slot are configured as flexible by one or more parameters, tdd-UL-DL-ConfigurationCommon and/or tdd-UL-DLConfigurationDedicated.

3 . The method of claim 1 , wherein,

in a case that the DCI format comprises at least one of the first information, the second information, and the third information, and the UE detects the DCI format providing a corresponding indication for the configured downlink transmission, receiving the configured downlink transmission on the set of symbols in the slot and on the set of RBs.

4 . The method of claim 3 , wherein the DCI format comprises a DCI format 2_0.

5 . The method of claim 1 , wherein the DCI format comprises the first information, and the first information indicates the set of symbols as downlink.

6 . The method of claim 1 , wherein the DCI format comprises the second information, and the second information indicates that the set of symbols are within the channel occupancy duration of the base station.

7 . The method of claim 1 , wherein the DCI format comprises the third information, and the third information indicates that one or more RB sets, where the set of RBs are allocated in, are available for reception.

8 . A user equipment (UE), comprising:

a memory;

a transceiver; and

a processor coupled to the memory and the transceiver; wherein:

the transceiver is configured, by a base station, to receive a downlink transmission on a set of symbols in a slot and a set of resource blocks (RBs);

the processor is configured to detect a downlink control information (DCI) format, wherein the DCI format comprises at least one of the followings:

a first information that is used to indicate one or more slot formats;

a second information that is used to indicate the channel occupancy duration of the base station; or

a third information that is used to indicate one or more RB sets availability for reception; and

the processor is configured to determine whether to receive or cancel reception of the configured downlink transmission on the set of symbols in the slot and on the set of RBs based on a content of the DCI format and a detection result of the DCI format, wherein,

in a case that the DCI format comprises at least one of the first information, the second information, and the third information, and the processor does not detect the DCI format providing a corresponding indication for the configured downlink transmission, the transceiver is configured to cancel the reception of the configured downlink transmission on the set of symbols in the slot and on the set of RBs; and

in a case that the DCI format does not comprise at least one of the first information, the second information, and the third information, and the processor does not detect the DCI format providing a corresponding indication for the configured downlink transmission, the transceiver is configured to receive the configured downlink transmission.

9 . The UE of claim 8 , wherein the set of symbols in the slot are configured as flexible by one or more parameters, tdd-UL-DL-ConfigurationCommon and/or tdd-UL-DLConfigurationDedicated.

10 . The UE of claim 8 , wherein the transceiver is further configured to receive the configured downlink transmission on the set of symbols in the slot and on the set of RBs in a case that the DCI format comprises at least one of the first information, the second information, and the third information, and the processor detects the DCI format providing a corresponding indication for the configured downlink transmission.

11 . The UE of claim 10 , wherein the DCI format comprises a DCI format 2_0.

12 . The UE of claim 8 , wherein the DCI format comprises the first information, and the first information indicates the set of symbols as downlink;

the DCI format comprises the second information, and the second information indicates that the set of symbols are within the channel occupancy duration of the base station; and/or

the DCI format comprises the third information, and the third information indicates that one or more RB sets, where the set of RBs are allocated in, are available for reception.
