摘要： A wireless receiver is disclosed that is capable of efficiently selecting a preferred transmission/detection scheme for use in wireless communication. The wireless receiver may be capable of communicating using any one of several transmission/detection schemes. Therefore, in order to select a preferred transmission/detection scheme, the wireless receiver calculates at least one metric for the transmission/detection schemes. In MIMO systems, the link adaptation is more complex and the metrics typically must be more accurate. Because of the potentially substantial amount of calculation that may be required to calculate the metric, the wireless receiver is capable of performing the individual calculations in optimized ways, as well as easily reducing the total number of metrics required to be calculated so as to reduce overall complexity.

摘要： A wireless communication device is disclosed that is capable of performing efficient measurements of secondary radio access technologies (RATs). The device includes multiple receiver chains. While operating in a first RAT, the device receives a measurement gap in order to perform measurements. Even though the measurement gap may be too small to adequately measure the other RAT, the device controls one of the receiver chains to measure the other RAT during a time period that overlaps with the measurement gap. In addition, when preparing for an inter-RAT handoff, the device controls one of the receiver chains to perform measurements regardless of whether a measurement gap has been received. In this manner, measurements of alternative RATs are efficiently performed, and handoff latency is significantly reduced.
