    摘要: Various schemes pertaining to extremely-high-throughput long training field, EHT-LTF, sequence design for distributed-tone resource units, dRUs, with peak-to-average power ratio, PAPR, reduction in 6GHz low-power indoor, LPI, systems are described. A communication entity distributes subcarriers of a RU with a resolution of four times, 4x, subcarrier spacing to generate a 4x EHT-LTF of an uplink, UL, trigger-based, TB, physical-layer protocol data unit, PPDU, with a dRU (8310). The communication entity then transmits the 4x EHT-LTF for the UL TB PPDU with the dRU (8320).

    摘要: An extreme-high-throughput, EHT, physical-layer protocol data unit, PPDU, is signaled between a first station, STA, and a second STA to indicate a resource unit, RU, allocation with respect to multiple users. One or more RU allocated to the first STA or the second STA as indicated in the EHT PPDU can be determined by using a RU allocation table that includes, in addition to entries corresponding to RUs allocatable to a plurality of users, one or more empty RU entries corresponding to one or more of an empty 242-tone RU, an empty 484-tone RU and an empty 996-tone RU.

    摘要: Embodiments of the present invention provide an apparatus and method for WLAN transmission over 320 MHz channels that use encoding and modulation schemes of existing 160 MHz tone plans defined in the IEEE 802.11ax standard. For example, 320MHz transmissions on a contiguous 320MHz channel or a non-contiguous 160MHz+160MHz channel can be performed using a 320MHz PPDU, or a 160MHz+160MHz PPDU, and the 320MHz/160 MHz+160 MHz PPDU can be defined using the 160MHz tone plan according to the IEEE 802.11ax standard. The existing tone plan of the IEEE 802.11ax standard is modified as described herein according to embodiments of the present invention. According to some embodiment, the 160MHz tone plan can be repurposed to support multi-link aggregation including 80MHz+240MHz transmission, or 160MHz+160MHz transmission using two or more links.

    摘要: Presented systems and methods facilitate efficient and effective communication interference mitigation. In one embodiment, a method comprises: configuring a payload portion of information in a normal transmission sub-channel (810); puncturing information in a punctured sub-channel (820); adjusting a mitigation sub-channel use to mitigate interference associated with the punctured sub-channel (830); and transmitting the information in the normal transmission sub-channel, the punctured sub-channel, and the mitigation sub-channel (840).
