Abstract: Novel channel estimation techniques that can be performed solely in the analog domain are provided. The techniques use continuous analog channel estimation (CACE), periodic analog channel estimation (PACE), and multiantenna frequency shift reference (MAFSR). These techniques provide sufficient channel knowledge to enable analog beamforming at the receiver while significantly reducing the estimation overhead. These schemes involve transmission of a reference tone of a known frequency, either continuously along with the data (CACE, MAFSR) or in a separate phase from data (PACE). Analysis of the methods show that sufficient receiver beamforming gain can be achieved in sparse channels by building the beamformer using just the amplitude and phase estimates of the reference tone from each receiver antenna.

Abstract: A non-access point (AP) MLD comprises STAs, each comprising a transceiver that forms a link with a corresponding AP of an AP MLD, and a processor. A restricted TWT (R-TWT) schedule is established on a first link, and a first STA on that link is a member of an R-TWT service period (SP) on that link. A second STA on a second link is not a member of any R-TWT SP on that link that overlaps with the R-TWT SP on the first link. The processor transitions the non-AP MLD into EMLSR operation wherein the first and second links form an EMLSR link pair, determines that a transmission opportunity (TXOP) has begun on the second link, and coordinates between the STAs such that a frame exchange sequence with the AP MLD on the second link during the TXOP does not overlap with the R-TWT SP on the first link.
