摘要： A physical channel processor on a wireless device and method for precoding for spatial multiplexing in an open-loop multiple-input multiple-output (MIMO) mobile communication system is disclosed. The method comprises the operation of receiving an input vector block from a layer mapper. The input vector block includes user equipment-specific reference signals (UE-RSs) or data in a physical downlink shared channel (PDSCH). The operation of generating a large delay cyclic delay diversity (CDD) vector block from the input vector block using a precoder configured for large delay CDD on an antenna port follows. The data can be resource element mapped with UE-RSs or channel-state information reference signals (CSI-RSs) in a physical resource block (PRB).

摘要： Embodiments of a high-efficiency WLAN (HEW) master station and method for communicating in a Wireless Network are generally described herein. In some embodiments, the HEW master station comprises a receiver configured to receive an uplink multi-user multiple-input multiple-output (MU-MIMO) transmission from a plurality of scheduled HEW stations. The uplink MU-MIMO transmission may comprise at least an HEW short-training field (STF) (HEW-STF) transmitted by each of the scheduled HEW stations. The HEW-STFs received from the HEW stations are distinguishable. The master station may process the HEW-STFs received from the scheduled HEW stations to set receiver gain for reception of UL-MIMO data from the scheduled HEW stations. In some embodiments, a single automatic gain control (AGC) setting may be determined from the combined HEW-STF resulting in improved receiver performance in UL MU-MIMO.

摘要： Disclosed in some examples are devices (e.g., APs and STAs), systems, methods, and machine readable mediums for allowing proper channel estimations (e.g., frequency offset estimation) in MU UL-MIMO systems. In some examples, each STA is allowed to send a signal on the same Orthogonal Frequency Division Multiplexing (OFDM) tone across different times of the preamble. By checking the phase difference on the same frequency across the different symbols in the preamble, an access point (AP) may estimate the frequency offset.
