Abstract: An embodiment is method performed by an access point (AP) for performing a joint transmission to jointly transmitting a frame to a station (STA) with one or more other APs. The method includes determining a scrambling seed that is to be used for the joint transmission, determining a basic service set (BSS) color for a virtual BSS that is jointly operated by the AP and the one or more other APs based on identifiers associated with the AP and the one or more other APs, and transmitting, as part of the joint transmission, a frame to the STA using the scrambling seed, wherein a preamble of the frame indicates the BSS color for the virtual BSS.

Abstract: An embodiment is method performed by a relay station (STA) that acts as a relay between a source STA and a destination STA. The method includes wirelessly receiving a physical layer protocol data unit (PPDU) from the source STA in a first channel, while receiving the PPDU from the source STA in the first channel, relaying the PPDU to the destination STA in a second channel that is different from the first channel, and responsive to detecting an error in receiving the PPDU from the source STA, ending the relaying of the PPDU to the destination STA early.

Abstract: An embodiment is method performed by a first wireless device in a wireless network to implement a block acknowledgement (ACK) scheme for acknowledging data frames received in multiple subchannels. The method includes receiving a plurality of data frames from a second wireless device in a plurality of subchannels, transmitting a block ACK frame to the second wireless device in one of the plurality of subchannels, wherein the block ACK frame includes ACK information for the plurality of subchannels, and wirelessly transmitting one or more data frames to the second wireless device in one or more of the plurality of subchannels, wherein the block ACK frame and the one or more data frames are transmitted simultaneously in different subchannels. The block ACK scheme may improve channel utilization, throughput, and/or latency in the wireless network.

Abstract: An over-restriction problem in extended restricted target wake time (rTWT) for overlapping basic service set (OBSS) networks is addressed by controlling the transmit power of OBSS packets during the rTWT service period (SP). This allows OBSS transmissions to occur concurrently with low latency traffic while minimizing interference. This approach mitigates the over-restriction problem and improves network efficiency. In one embodiment, a station in the OBSS can transmit data packets during the rTWT SP, if it has not received the beacon frame directly from the access point (AP) in the basic service set (BSS). In another embodiment, an AP in the OBSS provides extended rTWT metric information to help stations determine their maximum transmit power level during the rTWT SP. This enables stations to transmit data packets while minimizing interference to low latency transmissions in the BSS, thus mitigating the over-restriction problem.
