摘要： Embodiments of the present invention provide improved multi-link operation over EML links. A non-AP MLD indicating support of EMLMR operation announces it's the number of spatial streams supported for receiving or transmitting after receiving the initial frame exchange during enhanced multi-link multi-radio (EMLMR) operation (MLD level capabilities). MLD level capabilities for operating over the EMLSR links is defined so that the EMLMR capable devices can improve/optimize their performance based on their computing capabilities and RF design.

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 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 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 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 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.

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. 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; and (ii) after an end of the TXOP, the STA switches to the primary frequency segment.

摘要： An apparatus (e.g., an access point (AP) or a non-AP station (STA)) detects a non-primary subband of an operating bandwidth comprising a primary subband and the non-primary subband to be idle. The apparatus controls a transmit power in performing transmission on at least the non-primary subband.

摘要： A non-access point (non-AP) station (STA) multi-link device (MLD) receives a transmission from an access point (AP) MLD. In response to receiving the transmission, the non-AP STA MLD communicates with the AP MLD using an increased number of spatial streams with multi-link dynamic antenna switching at the non-AP STA MLD.
