Abstract: Enhanced protocols and devices may be used to alleviate loss of spectrum efficiency in wideband transmission. The protocols may implement a wideband transmission opportunity (TXOP) truncation where one or more of the channels involved in communication over the wideband are released. In one scenario, an access point (AP) may receive, from a wireless transmit receive unit (WTRU), a first CF-End frame that includes a duration field and a basic service set identifier (BSSID) field that includes an individual/group bit. On a condition that the individual/group bit of the BSSID field has a value of one (1), the AP may determine that a scrambling sequence of the first CF-End frame indicates a bandwidth associated with a transmit opportunity (TXOP) being truncated by the WTRU. The AP may then transmit a second CF-End frame at the bandwidth indicated by the scrambling sequence of the first CF-End frame.

Abstract: A medium access control (MAC) frame may have a MAC header that includes two address fields and a MAC frame version indicator.

Abstract: Methods and apparatuses are described herein for determining a transmit power based on clear channel assessment (CCA) thresholds. A station (STA) associated with a first Basic Service Set (BSS) may receive, from an access point (AP) associated with the first BSS, a clear channel assessment (CCA) value for a group of STAs associated with a second BSS. The CCA value may indicate a minimum CCA threshold for a packet received from the second BSS. The STA may then determine, based on the CCA value, a STA specific CCA parameter and a target CCA parameter. The target CCA parameter may be greater than or equal to the STA specific CCA parameter. Based on the STA specific CCA parameter and the target CCA parameter, the STA may determine a target transmit power control (TPC) parameter of the STA, wherein the sum of target TPC parameter and target CCA parameter is constant.
