摘要： A wireless node receives a beacon from a wireless access point. The beacon includes a wireless protocol time synchronization function (TSF) timestamp generated with reference to a global clock for a network. The wireless node synchronizes a counter according to the TSF timestamp. The wireless node receives a global timing offset (GTO) packet from the wireless access point and combines the GTO packet with a counter value to generate a global timestamp.

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： 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.
