    摘要: Embodiments of the present invention provide methods and devices for performing wireless sensing operations that can accommodate different Rx frequency responses with minimum PHY changes to increase the performance and reliability of wireless sensing in wireless local area network, WLAN, networks. Rx frequency response information can be obtained as channel state information, CSI, in a loopback test and can further be normalized with the total gain in the receiver chain leading to CSI estimation. Moreover, different Rx frequency responses can be categorized into limited groups with underlying circuit conditions based on their frequency response variations. The different Rx frequency responses can be indicated in subfields of a CSI report transmitted to the sensing initiator for performing sensing operations with the sensing responder.

    摘要: Techniques pertaining to preamble designs for next-generation wireless local area networks, WLANs, in 60GHz band are described. A first apparatus communicates in a 60GHz band wirelessly with a second apparatus (910) by transmitting a first physical-layer protocol data unit, PPDU, to the second apparatus (912) and/or receiving a second PPDU from the second apparatus (914). Each of the first PPDU and the second PPDU and a respective preamble thereof are either with or without at least partial backward compatibility with one or more preexisting PPDU formats and preambles.

    摘要: Methods and apparatus are provided for structured resource allocation signaling. In one novel aspect, an 8-bit RU allocation filed is allocated in the HE-SIG-B common field for each 20MHz. The structured resource signaling supports more than four MU-MIMO users. In one embodiment, the STA decodes the 8-bit RU allocation signal following a structured resource unit (RU) allocation rule, and determines the RU. In one embodiment, the STA decodes the first two bits of the 8-bit RU allocation signal to determine a first category of the RU allocation. The categories of the RU allocation includes a large RU size category indicating larger than 20MHz RUs exist, a two 106-tone category indicating two 106-tone RUs exist, and a no-large-RU category indicating only smaller-than-242-tone RUs exist. The STA further decodes based on the category. A lookup table (LUT) for RU allocation is built and decoded based on a structured signaling rule.
