摘要： Various schemes pertaining to optimization of distributed-tone resource unit, dRU, and distributed-tone multi-resource unit, dMRU, designs for transmission in a 6GHz low-power indoor, LPI, system are described. An apparatus distributes a plurality of subcarriers of a resource unit, RU, to generate a dRU or a distributed-tone multi-RU, dMRU, on an 80MHz frequency segment or subblock (3510). The apparatus then communicates with a communication entity using the dRU or the dMRU (3520).

摘要： Various schemes pertaining to pilot tone design for distributed-tone resource units, dRUs, in 6GHz low-power indoor, LPI, systems are described. A communication entity generates pilot tones of a dRU based on a hierarchical structure of pilot tones that is used for a regular resource unit, rRU, (4510). The communication entity then communicates with another communication entity using the dRU (4520).

摘要： Various schemes pertaining to subcarrier indices for distributed-tone resource units, RUs, in 6GHz low-power indoor, LPI, systems are described. A communication entity distributes frequency tones of a RU over a distribution bandwidth as a distributed-tone RU, dRU, (3210). The communication entity also generates generating a plurality of subcarrier indices for the distributed-tone RU such that a distribution of the distributed-tone RU is symmetric or asymmetric to a direct-current, DC, tone along an axis of subcarrier indices (3220). The communication entity then communicates wirelessly using the distributed-tone RU in a 6GHz LPI system (3230).

摘要： Various examples pertaining to signaling of punctured sub-channels in wireless communications are described. A puncturing pattern is signaled with an extremely-high-throughput, EHT, physical-layer protocol data unit, PPDU, (610). A first station, STA, and a second STA then communicate with each other based on the signaled puncturing pattern (620).

摘要： An access point, AP, and a station, STA, communicate with each other, with the AP indicating to the STA either or both of a preamble detection, PD, channel and a signaling, SIG, content channel and with the STA being initially monitoring a primary frequency segment of a plurality of frequency segments in an operating bandwidth of the AP (1510). A downlink, DL, or triggered uplink, UL, communication is performed between the AP and the STA during a transmission opportunity, TXOP, such that: (i) during the TXOP, the STA monitors a preamble on the PD channel and decodes a SIG content on the SIG content channel (1520); and (ii) after an end of the TXOP, the STA switches to the primary frequency segment.

摘要： Communications between an access point, AP, and a non-AP station, STA, are established in a plurality of frequency segments within a basic service set, BSS, bandwidth (1410) or on at least a first link and a second link. An extreme-high-throughput, EHT, subchannel selective transmission, SST, operation is performed between the AP and the non-AP STA in the plurality of frequency segments (1420) or on the first link and the second link. A trigger-enabled target wake time, TWT, session period, SP, for the EHT SST operation by either indicating one of the plurality of frequency segments as containing a resource unit, RU, allocation addressed to the non-AP STA (1422) or indicating one of the first link and the second link on which an operating frequency segment is located during the TWT SP.

摘要： 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 (1010). The process data is then transmitted to a receiving entity over at least some of a plurality of resource units, RUs, (1020). 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 (1012); 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 (1014).

摘要： Embodiments of the present invention provide a punctured preamble enabling wireless devices to efficiently use a channel (e.g., an 80 or 160 MHz channel) where a primary service is operating. A Wideband Channel Access Mechanism for 20 MHz/80 MHz operating STAs is provided so that a 20 MHz/80 MHz operating STA can dynamically move to a secondary channel to improve wireless performance of the STA. An AP coordinates the operating channel switch of the 20 MHz/80 MHz operating STA. An EHT cooperative multi-band operation can be applied to the preamble punctured PPDU for simultaneous multi-band operation.

摘要： Embodiments of the present invention provide a method and apparatus for hybrid ARQ acknowledgement and retransmission requests for decoding failed MPDUs of an A-MPDU received by an STA. The source address and receiver address of a failed MPDU can be verified according to a MAC header CRC that can be included in an A-Control frame, for example (1705). For verifying the source address and the receiver address in MAC header, according to some embodiments, the MAC header CRC is jointly calculated over the first two octets of the MPDU delimiter of an A-MPDU subframe.
Moreover, a Hybrid ARQ frame is defined to include Block Ack Bitmap subfield representing the received status of a plurality of MPDUs according to starting sequence control number, for example.
