Estimating a quantity of active users for collision control in an uplink resource pool

A method for wireless communication by a user equipment (UE), comprising:

• receiving a message that allocates one or more resources for a common power signal associated with a set of UEs comprising at least the UE;
• transmitting the common power signal via at least one resource of the one or more resources based at least in part on the message;
• and
• receiving control signaling that indicates one of a resource pool for autonomous transmission of uplink data by the set of UEs or a configured grant procedure for subsequent transmissions of the uplink data by the set of UEs based at least in part on the common power signal.

A non-transitory computer-readable medium storing code for wireless communication, the code comprising instructions executable by one or more processors to:

• receive a message that allocates one or more resources for a common power signal associated with a set of UEs;
• transmit the common power signal via at least one resource of the one or more resources based at least in part on the message;
• and
• receive control signaling that indicates one of a resource pool for autonomous transmission of uplink data by the set of UEs or a configured grant procedure for subsequent transmissions of the uplink data by the set of UEs based at least in part on the common power signal.
