Techniques for assisting performance of listen before talk procedures and uplink traffic multiplexing at user equipment

An apparatus for wireless communication at a user equipment (UE), comprising:

• means for receiving, over the air, in an uplink grant for an uplink transmission, information indicative of one of multiple types of Listen Before Talk (LBT) procedures, each of the multiple types of LBT procedures being associated with the uplink transmission, and wherein the information indicative of the one of multiple types of LBT procedures comprises at least one bit received in the uplink grant;
• means for identifying, from the received information, the indicated type of LBT procedure to perform for the uplink transmission;
• and
• means for performing, for a shared spectrum, the indicated type of LBT procedure for the uplink transmission.

An apparatus for wireless communication at a user equipment (UE), comprising:

• a processor;
• and
• memory coupled to the processor, wherein the processor is configured to:
• receive, over the air, in an uplink grant for an uplink transmission, information indicative of one of multiple types of Listen Before Talk (LBT) procedures, each of the multiple types of LBT procedures being associated with the uplink transmission, and wherein the information indicative of the one of multiple types of LBT procedures comprises at least one bit received in the uplink grant;
• identify, from the received information, the indicated type of LBT procedure to perform for the uplink transmission;
• and
• perform, for a shared spectrum, the indicated type of LBT procedure for the uplink transmission.

A non-transitory computer-readable medium for storing instructions executable by a processor of a user equipment (UE), comprising:

• instructions to receive, over the air, in an uplink grant for an uplink transmission, information indicative of one of multiple types of Listen Before Talk (LBT) procedures, each of the multiple types of LBT procedures being associated with the uplink transmission, and wherein the information indicative of the one of multiple types of LBT procedures comprises at least one bit received in the uplink grant;
• instructions to identify, from the received information, the indicated type of LBT procedure to perform for the uplink transmission;
• and
• instructions to perform, for a shared spectrum, the indicated type of LBT procedure for the uplink transmission.

An apparatus for wireless communication at a network access device, comprising:

• a processor;
• and
• memory coupled to the processor, wherein the processor is configured to:
• schedule an uplink transmission of a user equipment (UE) in a shared spectrum;
• and
• transmit, over the air, in an uplink grant to the UE for the uplink transmission, information indicative of one of multiple types of Listen Before Talk (LBT) procedures, each of the multiple types of LBT procedures being associated with the uplink transmission, and wherein the information indicative of the one of multiple types of LBT procedures comprises at least one bit in the uplink grant.

A method for wireless communication, comprising:

• determining an amount of queued traffic associated with each Listen Before Talk (LBT) priority class of a plurality of LBT priority classes;
• selecting a first LBT priority class for performing a LBT procedure;
• inverting a first amount of the queued traffic associated with the first LBT priority class with a second amount of the queued traffic associated with a second LBT priority class;
• performing the LBT procedure based at least in part on the selected first LBT priority class to contend for access to a shared spectrum;
• and
• transmitting, upon winning contention for access to the shared spectrum, at least some of the second amount of the queued traffic, wherein the first LBT priority class is a lower priority class than the second LBT priority class.
