摘要： A method of adjusting single-stream transmissions by a wireless device based on channel state information (CSI). The wireless device generates a sounding packet formatted for transmission via multiple spatial streams, and transmits the sounding packet to a receiving device via a single one of the multiple spatial streams. For example, the wireless device may be a single-antenna device. The wireless device further receives channel state information (CSI) from the receiving device based at least in part on the sounding packet. The wireless device then adjusts one or more characteristics of single-stream transmissions to the receiving device based at least in part on the received CSI.

摘要： A method of performing dynamic sounding in a wireless communication device includes determining whether to perform sounding based on an age of current channel state information (CSI). An achievable throughput can be recorded as a reference throughput after performing the sounding. A current achievable throughput can be compared with the reference throughput. A CSI timestamp can be reset when the current throughput is above the reference throughput by a first predetermined amount, thereby prolonging a lifespan of the current CSI. The CSI timestamp can be reduced when the current throughput is below the reference throughput by a second predetermined amount, thereby reducing the lifespan of the current CSI.

摘要： Methods, systems, devices, and apparatuses are described for wireless communications in which first type of traffic may be transmitted from a gateway access point (AP) directly to a station. Beacon signals transmitted to the station are transmitted as part of the first type of traffic. A second type of traffic may be transmitted from the gateway AP to the station via at least one relay AP. The first type of traffic may include low-throughput traffic and may be transmitted over a long-range radio link ( e.g. , 2 GHz band link or sub-1 GHz band link). The second type of traffic may include high-throughput traffic and may be transmitted over at least one short-range radio link ( e.g. , 5 GHz band link). The gateway AP may receive low-throughput traffic directly from the station and high-throughput traffic from the station via the at least one relay AP.

摘要： A wireless device is configured to switch data rates to account for temporary channel conditions or device configuration errors. Pre-selected data rates, more likely to achieve maximum goodput, are stored in a data rate table. The data rate table contains candidate data rates for each pre-selected data rate in the data rate table. When probe transmissions using the preselected data rates fail, dynamic rate probing is utilized to determine a possible cause and extent of the problem. The dynamic rate probing scheme transmits probe transmissions using the candidate data rates and tracks success or failure of these probe transmissions. An analysis of the probe transmissions is used to indicate a possible cause and/or extent of the problematic condition and to determine whether there is a need to reconfigure the data rates in the data rate table.

摘要： A fast diversity technique using either an EESM or a capacity computation can determine antenna selection in a wireless communication device. A fast Fourier transform (FFT) for the EESM/ capacity computation can be performed with consecutive samples of a single symbol period of a short training field (STF) of a packet received by each antenna (304,306). The effective signal-to-noise ratio (SNR) for each antenna can be calculated using the results of the EESM or capacity computation (307). The antenna with the highest effective SNR is selected (308).
