    摘要: Certain embodiments herein relate to an interleaver based on usable tones of a resource allocation. The interleaver is selected according to the number of usable tones and may be selected for each resource allocation to accommodate the variance in usable tones. The selected codebit interleaver or symbol interleaver may be a block interleaver in which bits are sequentially read in row by row and read out column by column, such that any unfilled entries in the block interleaver are skipped.

    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.

    摘要: Various embodiments are generally directed to techniques to identify the target of a packet in a wireless network. A transmitter node may include a connection identifier to generate a unique identifier corresponding to a connection between the transmitter node and a receiver node in the wireless network and a data packet transmitter to embed the unique identifier into a physical layer convergence protocol header corresponding to a packet to be transmitted to the receiver node. A node may include a data packet receiver to receive a physical layer convergence protocol header corresponding to a packet to be transmitted from a transmitter node in the wireless network to a receiver node in the wireless network and a header decoder to decode a unique identifier from the physical layer convergence protocol header, the unique identifier corresponding to a connection between the transmitter node and the receiver node.

    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.
