Contention based uplink transmissions for latency reduction

An apparatus for wireless communication, comprising:

• a processor;
• memory in electronic communication with the processor;
• and
• instructions stored in the memory, the instructions being executable by the processor to:
• identify data to be transmitted using a set of uplink resources;
• determine that an elapsed time since a prior scheduling request (SR) was transmitted exceeds a threshold;
• determine that the data is to be transmitted using a contention-based subset of the uplink resources based at least in part on determining that the elapsed time exceeds the threshold;
• and
• transmit the data using the contention-based subset of the uplink resources.

An apparatus for wireless communication, comprising:

• means for identifying data to be transmitted using a set of uplink resources;
• means for determining that an elapsed time since a prior scheduling request (SR) was transmitted exceeds a threshold;
• means for determining that the data is to be transmitted using a contention-based subset of the uplink resources based at least in part on determining that the elapsed time exceeds the threshold;
• and
• means for transmitting the data using the contention-based subset of the uplink resources.

A non-transitory computer-readable medium storing computer-executable code for wireless communication, the code comprising instructions executable to:

• identify data to be transmitted using a set of uplink resources;
• determine that an elapsed time since a prior scheduling request (SR) was transmitted exceeds a threshold;
• determine that the data is to be transmitted using a contention-based subset of the uplink resources based at least in part on determining that the elapsed time exceeds the threshold;
• and
• transmit the data using the contention-based subset of the uplink resources.
