Claim of US Patent No. 10,798,687

1. An apparatus configured to be employed in a user equipment (“UE”) comprising:memory to store executable instructions; and
one or more processors coupled with the memory to execute the executable instructions for one or more executable components comprising:
a communication component to transmit or receive signals on at least one of: an unlicensed band or a licensed band;
a scheduling component to process a downlink (“DL”) transmission that includes one or more UL grants and one or more indications within a first transmission opportunity that enables scheduling one or more uplink (“UL”) transmissions associated with a physical UL shared channel (“PUSCH”) or a physical UL control channel (“PUCCH”), wherein the one or more indications include an indication to schedule the one or more UL transmissions within a second transmission opportunity that is different than the first transmission opportunity; and
a listen before talk (“LBT”) component to:
perform a category 4 LBT protocol with a self-deference interval in response to the indication to schedule the one or more UL transmissions within the second transmission opportunity, wherein to perform the category 4 LBT protocol with the self-deference interval, the LBT component is further to: perform the self-deference interval in response to the category 4 LBT protocol being completed before a boundary of a subframe in which at least one of the one or more UL transmissions are to be scheduled; and perform a clear channel assessment after the self-deference interval and before transmission of the one or more UL transmissions; and
transmit the one or more UL transmissions after a second symbol of the subframe based on a completion time of the category 4 LBT protocol with the self-deference interval.
