Channel occupancy time (COT)-structure indication

An apparatus, comprising:

• a transceiver configured to:
• communicate, by a first wireless communication device with a second wireless communication device, a first indicator indicating at least one of a subband configuration for a channel occupancy time (COT) or a duration of the COT;
• communicate, by the first wireless communication device with the second wireless communication device during the COT, a first communication signal based on the at least one of the subband configuration for the COT or the duration of the COT;
• communicate, by the first wireless communication device with the second wireless communication device during the COT, a second indicator indicating an update for the at least one of the subband configuration for the COT or the duration of the COT, wherein the second indicator comprises an uplink (UL) grant indicating one or more valid subbands of the subband configuration based on one or more listen-before-talk (LBT) results at a base station (BS);
• and
• communicate, by the first wireless communication device with the second wireless communication device during the COT, a second communication signal based on the update.

A non-transitory computer-readable medium having program code recorded thereon for execution by a processor, the program code comprising:

• code for causing a first wireless communication device to communicate with a second wireless communication device, a first indicator indicating at least one of a subband configuration for a channel occupancy time (COT) or a duration of the COT;
• code for causing the first wireless communication device to communicate with the second wireless communication device, a first communication signal based on the at least one of the subband configuration for the COT or the duration of the COT;
• code for causing the first wireless communication device to communicate with the second wireless communication device, a second indicator indicating an update for the at least one of the subband configuration for the COT or the duration of the COT, wherein the second indicator comprises an uplink (UL) grant indicating one or more valid subbands of the subband configuration based on one or more listen-before-talk (LBT) results at a base station (BS);
• and
• code for causing the first wireless communication device to communicate with the second wireless communication device, a second communication signal based on the update.

An apparatus, comprising:

• means for communicating with a second wireless communication device, a first indicator indicating at least one of a subband configuration for a channel occupancy time (COT) or a duration of the COT;
• means for communicating with the second wireless communication device during the COT, a first communication signal based on the at least one of the subband configuration for the COT or the duration of the COT;
• means for communicating with the second wireless communication device during the COT, a second indicator indicating an update for the at least one of the subband configuration for the COT or the duration of the COT, wherein the second indicator comprises an uplink (UL) grant indicating one or more valid subbands of the subband configuration based on one or more listen-before-talk (LBT) results at a base station (BS);
• and
• means for communicating with the second wireless communication device during the COT, a second communication signal based on the update.
