摘要： A method of wireless communication includes selecting three or more reference signal symbols from at least two subframes detected within a measurement window location during a connected mode gap. The selected reference signal symbols are selected from reference signal symbols of at least one non-MBSFN subframe and one reference signal symbol of a special subframe. The method also includes combining the selected reference signal symbols and estimating a reference signal received power (RSRP) based at least in part on a result of the combining.

摘要： Methods, systems, and apparatuses to estimate a channel with discontinuous instances of a pilot signal. A pilot signal is received during a first and second time period. The time periods are separated by a blank period. The pilot signal is not received during the blank period. A pilot signal received during the second time period is combined with a pilot signal received during the first time period. A channel estimate is based on the combination. According to a second method, pilot signals are received. A first and second channel estimate is calculated based on the pilot signals. Data symbols are received following the pilot signals. A third channel estimate is extrapolated from the channel estimates. This channel estimate corresponds to a virtualized instance of the pilot signal. The data symbols are interpolated based on the second and third channel estimates.

摘要： Certain aspects of the present disclosure propose methods and apparatus for lowcomplexity soft- in soft-out detection that divide a plurality of received symbols into a plurality of groups of symbols and performs preprocessing on the symbols in each group to suppress interference from other groups. The preprocessing may utilze a priori information for one or more symbols in one or more groups that are not yet detected, and/or a posteriori information for one or more symbols in one or more groups that are already detected and/or decoded. The preprocessed symbols may then be detected using a soft- in soft-out detection algorithm. This detection method is applied to Iteractive Detection and Decoding (IDD) receivers.
