Techniques for identifying resources to transmit a channel reservation signal

An apparatus for wireless communications, comprising:

• a processor;
• memory in electronic communication with the processor;
• and
• instructions stored in the memory, the instructions being executable by the processor to:
• contend, at a user equipment (UE), for access to a channel of a shared radio frequency spectrum band;
• determine, based at least in part on the contending, that the channel of the shared radio frequency spectrum band is available;
• identify a number of frequency resources of the channel of the shared radio frequency spectrum band that are allocated to the UE for at least one uplink transmission following the contention for access, the number of frequency resources includes at least one frequency resource allocated to a physical uplink shared channel (PUSCH);
• and
• transmit, based at least in part on the determination, a channel reservation signal using a set of frequency resources associated with the identified number of frequency resources the channel reservation signal comprises an uplink channel usage beacon signal (U-CUBS).
