Abstract: Techniques pertaining to an efficient pre-channel reservation mechanism for target wake time (TWT) and restricted TWT (rTWT) in overlapping basic service set (OBSS) dense networks are described. A first station (STA) transmits a frame to reserve a reservation period. The first STA then communicates with a second STA during the reservation period which aligns at least partially with a target wake time (TWT) service period (SP) or a restricted TWT (rTWT) SP of the second STA.

Abstract: A wireless communication terminal operating as a Station (STA) is provided. The wireless communication terminal includes a wireless transceiver and a controller. The wireless transceiver performs wireless transmission and reception to and from an Access Point (AP). The controller receives a trigger frame including a Resource Unit (RU) Allocation subfield which has one bit to indicate support of 320 MHz bandwidth from the AP via the wireless transceiver, determines a combination of RUs to be used in a Trigger-Based Physical layer Protocol Data Unit (TB PPDU) according to the RU Allocation subfield, and sends the TB PPDU for Uplink (UL) data transmission to the AP via the wireless transceiver in response to the trigger frame.
