Prioritization between uplink and sidelink communications

A user equipment (UE), comprising:

• a transceiver configured to communicate via an uplink and a sidelink;
• and
• a processor configured to perform operations, the operations comprising:
• determining that a first set of data is to be transmitted in the uplink, wherein the first set of data comprises at least a buffer status report (BSR) medium access control (MAC) control element (CE);
• assigning a first priority value to the first set of data, wherein the first priority value is associated with a first threshold;
• determining that a second set of data is to be transmitted in the sidelink;
• assigning a second priority value to the second set of data, wherein the second priority value is associated with a second threshold;
• determining that the first set of data and the second set of data are to be transmitted using a same resource at a same time, wherein the UE is configured to prioritize the second set of data when (i) the first priority value assigned to the first set of data is equal to or greater than a first threshold and (ii) the second priority value assigned to the second set of data is less than a second threshold;
• prioritizing the first set of data based on the BSR MAC CE that is to be transmitted in the uplink regardless of whether (i) the first priority value assigned to the first set of data is equal to or greater than the first threshold and whether (ii) the second priority value assigned to the second set of data is less than the second threshold;
• and
• transmitting the first set of data prior to transmitting the second set of data, based on prioritizing the first set of data.

An integrated circuit, comprising:

• circuitry configured to determine that a first set of data is to be transmitted in an uplink, wherein the first set of data comprises at least a buffer status report (BSR) medium access control (MAC) control element (CE);
• circuitry configured to assign a first priority value to the first set of data, wherein the first priority value is associated with a first threshold;
• circuitry configured to determine that a second set of data is to be transmitted in a sidelink;
• circuitry configured to assign a second priority value to the second set of data, wherein the second priority value is associated with a second threshold;
• circuitry configured to determine that the first set of data and the second set of data are to be transmitted using a same resource at a same time, wherein a user equipment (UE) is configured to prioritize the second set of data when (i) the first priority value assigned to the first set of data is equal to or greater than a first threshold and (ii) the second priority value assigned to the second set of data is less than a second threshold;
• circuitry configured to prioritize the first set of data based on the BSR MAC CE that is to be transmitted in the uplink regardless of whether (i) the first priority value assigned to the first set of data is equal to or greater than the first threshold and whether (ii) the second priority value assigned to the second set of data is less than the second threshold;
• and
• transmitting the first set of data prior to transmitting the second set of data, based on prioritizing the first set of data.
