Abstract:
Techniques pertaining to transmission methods of resource unit (RU) duplication and tone repetition for Enhanced Long Range (ELR) communications are described. An apparatus (e.g., station (STA)) generates a resource unit (RU) or multi-RU (MRU). The apparatus then performs an ELR communication wirelessly with either or both of: (a) duplication of the RU or MRU; and (b) repetition of tones of the RU or MRU.
Abstract:
Techniques pertaining to multi-link operation (MLO) assisted 60 GHz beamforming training and data transmission in wireless communications are described. An apparatus (e.g., as a 60 GHz-capable MLO station (STA)) performs MLO assisted 60 GHz operations by: (i) performing discovery and association; and (ii) performing either or both of beamforming training and data transmission in a 60 GHz band.
Abstract:
Techniques pertaining to designs of channelization of the 60 GHz band for next-generation wireless local area networks (WLANs) are described. A first apparatus communicates in a 60 GHz band wirelessly with a second apparatus by communicating with a channelization design of the 60 GHz band having a channel center frequency being equal to (a channel starting frequency+ΔF)+ΔF*channelIndex, with ΔF denoting a half of a channel spacing and with channelIndex denoting a channel index value.
Abstract:
A method of transmitting and receiving a HE PPDU and perform channel estimation enhancement is proposed. The HE PPDU comprises legacy preamble, HE-STF, HE-LTF, and data. A beam-change indication indicates if the pre-multiplied beamforming Q-matrix is changed from legacy preamble to H-SFT, HE-LTF, and data portion. A value of 1 indicates that Q matrix is changed. A value of 0 indicates that Q matrix is unchanged and receiver should be safe to combine L-LTF and HE-LTF. The beam-change indication can be used to significantly enhance channel estimation at receiver. When there is no beam-change, receiver does not change operation during HE-STF and HE-LTF such that the channel estimations can rely on the combination of L-LTFs, L-SIG, RL-SIG, HE-SIGAs and HE-LTF.

A method operative on a wireless transceiver device for performing beamforming calibration includes: measuring at least one joint signal response of at least one circuit loopback between a transmitter of the wireless transceiver device and a receiver of the wireless transceiver device to determine the measurement result; and calibrating joint signal path mismatch according to the measurement result for s multiple antenna beamforming system operating on the wireless transceiver device.
Abstract:
Techniques pertaining to distributed-tone resource unit (DRU) optimization to improve spectrum mask in wireless communications are described. An apparatus (e.g., a station (STA)) generates a DRU according to a tone plan. The apparatus also applies a first shift and a second shift to tones of the DRU in a first half of the tone plan and tones of the DRU in a second half of the tone plan, respectively. The apparatus then performs a wireless communication with the DRU.
Abstract:
Various schemes pertaining to distributed-tone resource unit (DRU)-based enhanced long range (ELR) communication schemes in wireless local area networks (WLANs) are described. An apparatus (e.g., an access point (AP) or a non-AP station (STA)) generates a DRU-based PPDU. The apparatus transmits the PPDU in an ELR communication.
Abstract:
Techniques pertaining to distributed-tone resource unit (DRU or dRU) transmission of frequency subblocks or frequency segments of wide bandwidths in wireless communications are described. An apparatus (e.g., station (STA)) generates a DRU with tones or subcarriers of the DRU distributed in a frequency segment or subblock. The apparatus then communicates wirelessly with the DRU in the frequency segment or subblock of a bandwidth of 240 MHz or wider.
Abstract:
Techniques pertaining to distributed-tone resource unit (DRU) allocation and scheduling for mixed-distribution bandwidth operations in wireless communications are described. An apparatus (e.g., access point (AP)) allocates a plurality of DRU sizes on a plurality of distribution bandwidths to a plurality of stations (STAs). The apparatus then communicates with one or more of the plurality of STAs with a plurality of DRUs that are scheduled with one or more of the plurality of DRU sizes on one or more of the plurality of distribution bandwidths such that there is no overlap of tones of the plurality of DRUs.
Abstract:
In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus may be a station (STA). In certain configurations, the STA transmits a request-to-send (RTS) frame in an enhanced long range (ELR) format for obtaining a transmission opportunity (TXOP). The STA receives a first clear-to-send (CTS) frame in the ELR format or a non-ELR format responding to the RTS frame. In response to receiving the first CTS frame, the STA transmits data in the ELR format in the TXOP. In certain configurations, the STA further receives an acknowledgement in the same format as the first CTS frame for responding to the data being transmitted. In certain configurations, prior to transmitting the RTS frame, the STA transmits a CTS-to-Self frame in the non-ELR format.
