Techniques and apparatuses for scheduling request acknowledgement

A method of wireless communications performed by a base station, comprising:

• receiving a scheduling request from a user equipment;
• and
• transmitting a response message to the user equipment based at least in part on receiving the scheduling request from the user equipment,
• wherein the response message includes an indicator indicating an assignment of uplink resources or that the assignment of uplink resources is to be provided after the response message is provided,
• wherein the response message is to suppress retransmission of the scheduling request, and
• wherein the response message indicates a time location for subsequent monitoring for the assignment of uplink resources when the indicator indicates that the assignment of uplink resources is to be provided after the response message is provided.

A user equipment, comprising:

• a memory;
• one or more processors coupled to the memory, the memory and the one or more processors configured to:
• transmit a scheduling request to a base station;
• and
• monitor for an ultra-reliable low latency communications type of response message from the base station based at least in part on transmitting the scheduling request to the base station,
• wherein the response message includes an indicator of an assignment of uplink resources for the user equipment or that the assignment of uplink resources is delayed,
• wherein, based at least in part on the monitoring, the user equipment avoids retransmission of the scheduling request when the response message is detected or retransmits the scheduling request without delay when the response message is not detected, and
• wherein the response message indicates a time location for subsequent monitoring for the assignment of uplink resources when the indicator indicates that the assignment of uplink resources is delayed.
