Abstract: Mechanisms of reducing beamforming feedback reporting sizes in WIFI communication. At a beamformee STA, beamforming feedback matrices generated from channel estimation are subject to two compression processes: first compressed to angles through Givens rotation and then further compressed by using source coding. The double compressed feedback information is transmitted in a report to the beamformer. Accordingly, the beamformer reconstructs the feedback matrices by first decompressing the reported information by source decoding and then further decompressing based on the Givens rotation. In some other embodiments, the beamformee STA uses a beambook to map the beamforming feedback matrices to predetermined beamforming vectors. The associated indices of the vectors, which may be compressed, are transmitted in a beamforming feedback report.

Abstract: Various proposed schemes pertaining to extreme high-throughput (EHT) preamble designs for transmissions to mixed clients in wireless communications are described. In one example, an aggregated Physical Layer Convergence Procedure (PLCP) protocol data unit (PPDU), which is transmitted over a plurality of 80-MHz bandwidths with data for a plurality of stations (STAs), is received. A preamble of a specific one of the plurality of 80-MHz bandwidths is then decoded.

Abstract: A joint sounding mechanism used in a multi-AP system to gain channel information for joint data transmission. Multiple sounding APs can transmit a joint sounding packet that includes training symbols for the antennas of all the sounding APs with regard to the transmission channel. The antennas of the multiple sounding APs may be treated as a virtual antenna array with global antenna indexes. The joint sounding packet may include a plurality of training fields, each field corresponding to a respective antenna in the virtual antenna array. Alternatively, the joint sounding packet has subcarrier-interleaved training fields, where each sounding AP transmits training symbols on an allocated set of non-pilot subcarriers. Channel status information (CSI) can be generated by the STAs in response to the joint sounding packet and supplied to the APs. Accordingly, the APs can perform antenna beamforming and transmit a data packet jointly on the transmission channel.

Abstract: Systems and methods of transmitting a multi-user (MU) wake-up packet in FDMA. In the wake-up setup stage, an STA informs the AP that it can resolve an MU wake-up packet transmitted in FDMA. Accordingly, AP allocates a frequency channel to the STA in a WUR setup response frame which indicates a channel offset relative to the primary channel. Moreover, if a WUR channel allocated to an STA is inaccessible or there is on pending wake-up signal for the STA, no wake-up signal is included in the MU wake-up packet while any other accessible allocated channels may still be utilized for transmitting the scheduled wake-up signals. During such a transmission, an inaccessible channel may be punctured; and an accessible channel having no pending wake-up signal may be used to carry an invalid wake-up signal or a legacy preamble followed with no wake-up signal.

Abstract: A method pertaining to optimization of resource unit (RU) and segment parser design for aggregated and multi-RU operations in extreme high-throughput (EHT) systems involves coding data for a station (STA) to provide a stream of coded bits. The method also involves processing the stream of coded bits to provide processed bits, including parsing the stream of coded bits to a combination of multiple RUs assigned to the STA in a proportional round-robin fashion. The method further involves transmitting the processed bits to the STA over the combination of multiple RUs.

Abstract: Various proposed schemes pertaining to interleaving of combinations of multiple resource units (RUs) in wireless local area networks (WLANs) are described. In one example, data in a service data unit (SDU) is processed. The process data is then transmitted to a receiving entity over at least some of a plurality of resource units (RUs). The processing of the data involves either: (i) performing tone mapping by using one joint tone interleaver on one or more combinations of multiple RUs of the plurality of RUs within one frequency segment of a predefined bandwidth; or (ii) performing tone mapping by using multiple tone interleavers on the one or more combinations of multiple RUs of the plurality of RUs over multiple frequency segments of the predefined bandwidth.

Abstract: A method of extremely high coding rates for next-generation wireless local area network (WLAN) systems involves coding an input data at a first coding rate using codes designed for coding up to a second coding rate lower than the first coding rate to provide a coded data. The method also involves wirelessly transmitting the coded data.

Abstract: Systems and methods of transmitting a PPDU to or from a single user station (STA) in an OFDMA transmission by using multiple RUs. An access point (AP) allocates multiple RUs to an STA for an OFDMA transmission and correspondingly specifies the STA ID repeatedly in the user specific field of a SIG-B field in a downlink PPDU, or in the user information fields of a trigger frame. Alternatively, multiple AIDs of the STA can be specified in the user specific field or the user information fields instead of repeating the same STA ID. An indication may be inserted in the SIG-A field to indicate that the enhanced RU allocation scheme is used for the OFDMA transmission.

Abstract: A method of very high throughput (VHT) operation information subfields design for IEEE 802.11 WLAN is proposed. The VHT operation information subfields comprise a channel width, a channel center frequency segment 0 (CCFS0), and a channel center frequency segment 1 (CCFS1). Multiple definitions of the VHT operation information subfields have been adopted by different access points (AP)s and wireless stations (STAs). In accordance with one novel aspect, upon receiving the VHT operation information element broadcasted by an AP, an STA will first check the channel width indicated by the AP. The STA then follows different definitions under different channel widths. Under such method, the STA can support up to 160 MHz operation mode with APs following different definitions and operating up to 160 MHz mode.

Abstract: An apparatus implemented in an access point (AP) participates in joint soundings together with one or more other APs in a joint multi-AP (JMAP) configuration to receive joint feedbacks from a plurality of stations (STAs) responding to the joint soundings. The apparatus then performs transmissions in a coordinated multi-AP (CMAP) configuration with the one or more other APs or in a single-AP configuration with no other AP based on the joint feedbacks received while in the JMAP configuration.

Abstract: An apparatus implemented in a master access point (AP) selects at least one basic service set (BSS) from one or more neighbor BSSs to form a spatial reuse group (SRG). The apparatus then performs coordinated spatial reuse (CSR) in the SRG with a set of overlapping basic service set (OBSS) power detection (PD) parameters.

Abstract: A wireless communicating method includes: performing one resource unit allocation upon a channel; and allocating a first resource unit and a second resource unit in said one resource unit allocation to a station, wherein the first resource unit is different from the second resource unit. By using the wireless communication method, throughput rate can be improved.

Abstract: Systems and methods of expanding indication capabilities of existent PPDU preamble fields. The “GI+LTF Size” field is redefined to indicate a new combination of GI duration and HE-LTF size. The redefinition is indicated when the values of the two other existent fields, in combination, indicate an invalid scenario because the two values should have been mutually exclusive. Particularly, the DCM field and the STBC field are both set to the “enabled” mode as an indication for redefine the “GI+LTF Size” field. Upon receiving such a PPDU, a receiver is configured to resolve the PPDU as neither DCM nor STBC is enabled. Rather, the receiver interprets the particular combination of DCM and STBC values as an indication that the “GI+LTF Size” field is redefined to indicate the new combination of GI duration and HE-LTF size.

Abstract: A method of joint encoding schemes with interleaver and tone mapper for multiple-resource unit (multi-RU) operation involves performing joint encoding of a plurality of information bits to generate a plurality of encoded bit sequences.

The method further involves transmitting the plurality of processed bit sequences over the plurality of RUs.

Abstract: An apparatus (e.g., an access point (AP) establishes a plurality of links comprising a primary link and at least a secondary link. The apparatus transmits a management frame on the primary link to indicate a multi-link capability of the AP. The apparatus configures the secondary link for one or more non-AP stations (STAs), which are capable of operating on the primary link and the secondary link, with multi-link capability and operating parameters through an association procedure on the primary link.

Abstract: A first access point (AP) receives a second spatial reuse parameter (SRP) related to a second AP from the second AP. The first AP transmits the second SRP to at least a first communication device associated with the first apparatus. The first AP then receives a uplink (UL) transmission from the first communication device with a transmit power of the UL transmission controlled based on the second SRP.

Abstract: A first apparatus communicates with a second apparatus via a first link in a first frequency band and via a second link in a second frequency band different than the first frequency band by performing operations. For example, the first apparatus performs an independent enhanced distributed channel access (EDCA) on each of the first link and the second link. Then, the first apparatus obtains a transmit opportunity (TXOP). Next, the first apparatus synchronizes a starting time and/or an ending time of a transmission and a reception on the first link and the second link to avoid causing an in-device coexistence (IDC) interference due to the transmission and the reception occurring simultaneously. Alternatively, the first apparatus refrains from transmitting and receiving on the first link and the second link simultaneously to avoid causing the IDC interference.
