摘要： Wireless communication devices with multiple receive (RX) chains may be operated to maintain high performance while saving power. This may be accomplished by evaluating signal strength during transmission of the RX packets, and/or evaluating a possible imbalance (gain difference) between the multiple RX chains within the wireless communication device. Signal strength (or good signal) detection may be enabled when non-MIMO (non-multiple-in-multiple-out) transmissions are taking place, while imbalance detection (antenna gain comparison) may be enabled when a specified number of single-stream packets have been received. Once the decision has been made to operate in a reduced number RX path mode, decision to reactivate one or more additional RX paths may be made based on MIMO detection, a detection of a drop in signal quality, and/or upon expiration of a power save timer.

The method can include a wireless communication device determining an active data traffic pattern; defining a threshold channel quality metric based at least in part on a threshold channel quality needed to support a threshold quality of service for the active data traffic pattern; comparing a measured channel quality to the threshold channel quality metric; and disabling receiver diversity in an instance in which the measured channel quality metric satisfies the threshold channel quality metric.

摘要： Switching between and/or combining various multi-transceiver wireless communication techniques based on a determined characteristic of a network or a wireless link is described herein. As an example, a characteristic such as signal to noise ratio (SNR), multi-path scattering, available bandwidth, or the like, can be determined. The characteristic can then be compared with suitable thresholds for various multi-transceiver communication techniques, such as MIMO, multi-channel concatenation, channel diversity, and so on. Based on a comparison of the characteristic and the thresholds, a suitable multi-transceiver technique can be selected and implemented for the wireless link Accordingly, a network can provide increased data rates and/or channel quality from a multi-transceiver technique that is most suited to prevailing conditions of the wireless network/link.

摘要： Examples are generally described that include methods for selecting a transmit mode in a communications system. An example method may include calculating a first transmission rate for data in a multiple-input multiple-output mode of the communications system and calculating a second transmission rate for the data in a single-input multiple-output mode of the communications system. A mode may be selected from the group consisting of the multiple-input multiple-output mode and the single-input multiple-output mode based, at least in part, on an energy consumption of the first and second transmission rates. Data may be transmitted from a transceiver in the communications system using the selected mode.

摘要： Methods, systems, and devices are described for receive chain diversity processing in a mobile wireless device. When data is not being received at the mobile device, the diversity receive chain(s) may be disabled in order to reduce power consumed at the mobile device. The diversity receive chain(s) may be enabled/disabled according to one or more different algorithms based on idle time from the receipt and/or transmission of data. The amount of idle time that triggers the disabling of a diversity receive chain may be adaptive based on historical usage of the mobile device, or based on activity on the transmit chain of the mobile device.
