Abstract: Various schemes pertaining to encoding and transmit power control for downsized trigger-based (TB) physical-layer protocol data unit (PPDU) transmissions in next-generation WLAN systems are described. A station (STA) receives a trigger frame indicating an allocated resource unit (RU) of a first size. The STA performs channel sensing responsive to receiving the trigger frame. In response to detecting at least one subchannel being busy from the channel sensing, the STA performs a downsized trigger-based (TB) transmission with a downsized RU or multi-RU (MRU) of a second size smaller than the first size by utilizing downsized RU or MRU allocation information while maintaining a value of each of one or more parameters unchanged in an encoding process to perform the downsized TB transmission.

An apparatus processes a plurality of subcarriers of a RU to generate a distributed-tone RU (dRU) or a distributed-tone multi-RU (dMRU). The apparatus then transmits the dRU or the dMRU to another apparatus. In processing the plurality of subcarriers, the apparatus codes a plurality of information bits by either LDPC encoding or BCC encoding and transmitting the plurality of subcarriers with one or more optimization parameters using a LDPC tone mapper or a BCC interleaver.

Abstract: Embodiments of the present invention provide a method and apparatus for coordinated multi-AP channel access in a wireless network. A wireless AP that obtains a transmission opportunity (TXOP) (a “coordinator AP”) can grant one or more STAs or APs under control of the coordinator AP the use of some of the bandwidth granted by the TXOP. The STAs or APs that are granted the use of the bandwidth are referred to as “coordinated APs.” Thereafter, a coordinator AP or a coordinated AP can create a new basic service set (BSS) of devices for coordinating data transmissions. For example, the coordinated AP may serve as a relay, where the coordinated AP services devices in a new BSS by sending and receiving data with a coordinator AP in a different BSS.

Abstract: A method pertaining to leftover bits processing for proportional round-robin resource unit (RU) parsing in extreme high-throughput (EHT) systems involves processing a stream of bits to provide processed bits. The method also involves transmitting the processed bits to a station (STA) over a combination of multiple resource units (RUs) assigned to the STA. In processing the stream of bits, the method may involve parsing the stream of bits to the combination of multiple RUs. Moreover, in an event of leftover bits remaining from the parsing, the method may further involve distributing the leftover bits to one or more RUs but not all RUs of the combination of multiple RUs.

Abstract: Systems and methods of WLAN communication including efficient spatial reuse mechanisms for relay transmissions between a repeater network and non-AP STAs in OFDMA. The non-AP STAs are grouped based on their connectivity with the individual repeaters and the radio coverage regions of the repeaters. Each group is either a non-overlapping group with the constituent non-AP STAs located in a non-overlapping coverage region of a particular repeater, or an overlapping group with the constituent non-AP STAs located in an overlapping coverage region of two or more repeaters. Based on the grouping, certain RUs (or subchannels) are reused for multiple groups without causing inter-group interference, thereby expanding the bandwidths used in the relay operations. RU allocation based on grouping can be used in combination with transmit power adjustment to achieve efficient spatial reuse in OFDMA.
