Claim:
1. A high-efficiency (HE) station comprising: memory; and, hardware processing circuitry coupled to the memory, the hardware processing circuitry configured to: receive a beacon frame that indicates a trigger frame (TF) timing for a beacon interval, wherein the beacon frame is received from an HE access point (AP) in channel resources that include multiple sub-channels; receive a random access TF that indicates a random access portion of the sub-channels that are allocated for random access contention during an uplink transmission period; determine a candidate sub-channel from the channel resources; when the candidate sub-channel is included in the random access portion, transmit an uplink frame on the candidate sub-channel during the uplink transmission period; refrain from transmission of the uplink frame when the candidate sub-channel is excluded from the random access portion; and when the candidate sub-channel is excluded from the random access portion:
