Abstract

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine a traffic stream, from among a plurality of traffic streams, for a semi-persistent scheduling (SPS) flow of a plurality of SPS flows based at least in part on one or more parameters associated with the traffic stream, wherein the one or more parameters include one or more of a periodicity associated with the traffic stream, a number of frequency resources associated with the traffic stream, or a proximity service per packet priority (PPPP) value associated with the traffic stream, and wherein a number of the plurality of traffic streams is greater than a number of the plurality of SPS flows. The UE may transmit traffic of the traffic stream in accordance with the SPS flow. Numerous other aspects are described.

5 . The UE of claim 1 , wherein the one or more parameters include a number of frequency resources associated with the at least one traffic stream.

6 . The UE of claim 5 , wherein the one or more processors, to determine the first traffic stream and the second traffic stream for the SPS flow, are configured to:

rank the plurality of traffic streams based at least in part on respective subchannel rates associated with the plurality of traffic streams.

7 . The UE of claim 6 , wherein the one or more processors, to rank the plurality of traffic streams, are configured to:

rank traffic streams, of the plurality of traffic streams, that are associated with equal subchannel rates based at least in part on priority classifications associated with the traffic streams associated with equal subchannel rates.

8 . The UE of claim 7 , wherein the priority classifications are based at least in part on PPPP values associated with the traffic streams associated with equal subchannel rates.
