SYSTEMS AND METHODS FOR SPATIAL COMPATIBILITY DETERMINATION AND WEIGHT GENERATION USING BEAMFORMED SOUNDING SIGNALS

原文（中文）

Systems and methods for spatial compatibility determination and weight determination include a base node transmitting a sequence of beamformed sounding signals to a plurality of nodes including at least two nodes; receiving, responsive to the sequence and at the base node, receive signal strength data and signal to interference data for each node of the plurality of nodes; and, calculating, at the base node, a compatibility metric for the at least two nodes. Scheduling the at least two nodes to use a same time-frequency resource based on the compatibility metric and, and transmitting signals using the same time-frequency resource to the at least two nodes, is described. Determining initial downlink and uplink payload transmit weights from the sequence of transmit beamforming sequences is described. Calculating a per-user transmit weight for a base station is also described. Predicting the expected channel quality, pathloss, and selection of signal modulation is described.
