Abstract: A single receive chain of a MIMO receiver is activated during a low power listen mode. Upon detecting a legacy short training field (L-STF) in a received packet, the single receive chain performs a first frequency estimation, and activates one or more additional receive chains of the MIMO receiver. The MIMO receiver uses maximal ratio combining (MRC) to receive the signal using the first receive chain and the one or more additional activated receive chains, wherein the MRC is based, at least in part, on the first frequency estimation. The MIMO receiver may determine whether the received packet is a high throughput/very high throughput (HT/VHT) packet, and if not, deactivate the one or more additional receive chains. In one alternative, the additional receive chains are not activated until determining that a HT/VHT packet has been received.
Abstract translation: MIMO接收机的单个接收链在低功率监听模式下被激活。 在接收到的分组中检测到遗留短训练场（L-STF）时，单个接收链执行第一频率估计，并激活MIMO接收机的一个或多个附加接收链。 MIMO接收机使用最大比率组合（MRC）来使用第一接收链和一个或多个附加的激活的接收链接收信号，其中MRC至少部分地基于第一频率估计。 MIMO接收机可以确定所接收的分组是高吞吐量/非常高吞吐量（HT / VHT）分组，如果不是，则去激活一个或多个附加的接收链。 在一个替代方案中，在确定已经接收到HT / VHT分组之前，不激活额外的接收链。

Abstract: A method of operating a receiver in a communications system is disclosed. The receiver receives a radio-frequency (RF) data signal and converts the RF data signal to an intermediate frequency. The receiver then determines whether a blocker image interferes with the received data signal, and selectively adjusts the intermediate frequency to which the data signal is converted based on the determination. The receiver may lower the intermediate frequency if the blocker image interferes with the received data signal. The receiver may also deactivate a quadrature chain of the receiver if the blocker image interferes with the received data signal.

Abstract: Methods, systems, and devices are described for power conservation in a wireless communications system. In embodiments, power conservation may be achieved by adaptively controlling power modes of a wireless communication device, using a modulation and coding scheme (MCS) value as a factor for guidance. According to one aspect, the device may be in a reception mode. While in a first power mode, the device may receive control information for incoming data that is being transmitted via a transmission frame. The control information may be located in a first portion of the frame with the data following in a second portion of the frame. The control information may include or otherwise indicate an MCS value corresponding to the MCS applied to the incoming data. Based on the MCS value, the device may be adaptively switched to a second power mode for receiving the incoming data.

Abstract: Methods, devices, and apparatuses are described for wireless communications using a multidimensional algorithm for roaming. In one aspect, an initial set of candidate access points (APs) is produced by a station using a roaming scan. The initial set may be identified based at least in part on an initial metric (e.g., beacon signal strength). A probe signal may be transmitted by the station to at least one of the candidate APs in the initial set and information may be received in response to the probe signals. The station may then identify a reduced set from the initial set based at least in part on the received information, where the reduced set is used to select a target AP. At least one additional metric may be identified and the probe signal may be configured to obtain information corresponding to the additional metrics. This information may be used by the station to select the candidate APs in the reduced set.

Abstract: In a multi-radio user equipment (UE) various techniques may be used to buffer communications for a first radio access technology (RAT). A low channel quality for a second RAT is reported. An indication to halt downlink communications of the second RAT based on the reported low channel quality is received. The buffered communications by the first RAT when the second RAT downlink communications are halted are transmitted. An indication to the second RAT is sent to resume normal channel quality reporting.
