摘要： Methods and systems for rectifying deteriorated channel conditions on a communication link are described. In response to the detection of a link deterioration event, a cluster of beams about a currently utilized beam pair can be trialed to determine a suitable, alternate pair of beams on which to establish a communication link. In turn, in the case of a link blockage event, a set of beams having a relatively large azimuthal angle with respect to a currently utilized beam pair can be trialed to determine a suitable beam pair for further communication.

摘要： A method for LTE or WiMAX scheduling includes collecting, by a basestation BS, channel feedback from multiple mobiles with downlink traffic. The channel feedback enables the BS to determine an achievable rate or block error probability if transmitting to a mobile with a given modulation and coding scheme MCS and multiple-input multiple-output MIMO mode. The method includes determining, by the BS, which of the mobiles is scheduled on each resource block RB and what the MCS and MIMO mode is selected for each scheduled mobile, and allocating bits on the set of the RBs assigned to each scheduled mobile.

摘要： Systems, methods and apparatuses for jointly demodulating data signals are disclosed. In accordance with the method, pilot signals are received from a base station and are processed. In addition, from a set of expected co-scheduled data streams, a subset of the co-scheduled data streams that are actually transmitted by the base station are determined based on the pilot signals. Further, a group of the transmitted co-scheduled data streams are selected from the determined subset. The data signals are received and jointly demodulated by employing the selected group of co-scheduled data streams and by suppressing non-selected data streams from the determined subset.
