摘要： In an example, packets transmitted over a communication channel from a transmitter are received. Channel state information (CSI) from the received packets are obtained and signal-to-noise (SNR) values of the communication channel are computed based on the obtained CSI. In addition, effective bit error rate (BER) values are determined based on the SNR values, a coherence time period within which the effective BER values of the communication channel remain within a predetermined range is determined, a modulation and coding scheme (MCS) to be implemented by the transmitter is determined based on the effective BER values within the coherence time period, and the determined MCS is transmitted to the transmitter.

摘要： A method for extrapolating channel state information (“CSI”) estimates from multiple packets sent over different channels to generate a combined CSI estimate for a MIMO-OFDM system is disclosed. Packets are received on an m×n×Wi channel configuration, wherein m is the number of receive antennas used to receive the packets, n is the number of transmit antennas used to transmit the packets, and Wi is the number of OFDM channels for a packet i in the MIMO-OFDM system. CSI estimates are generated for the received packets and the CSI estimates are extrapolated to generate a combined CSI estimate for an m×n×R channel configuration, wherein R>Wi.

摘要： Embodiments herein relate to transmitting information from wireless access points (WAP) sharing a same frequency channel that is part of an industrial, scientific and medical (ISM) radio band. During a beacon transmit period (BTP), the WAPs transmit a beacon. Then, a first WAP is to collect information from at least one of the plurality of communication devices (CD) associated with the first WAP during a control access period (CAP). Next, the first WAP transmits the collected information during an open access period (OAP).

摘要： Methods, devices, and machine readable media are provided for transmission in a network with active and sleeping clients. Some examples can include transmitting a first multicast stream of data in response to an active wireless client being associated with the wireless network device at a particular time. The method can include transmitting a second multicast stream of the data after the first multicast stream in response to a sleeping wireless client being associated with the wireless network device at the particular time and in response to a delivery traffic indication message count expiring. The first and/or second multicast streams of the data can be retransmitted a number of times (e.g., at different data rates). An active/sleep status can be maintained for the wireless clients. A unicast stream can be transmitted when the number of clients does not exceed a threshold.
