Abstract: A system and method for providing at least one transmit precoder includes transforming at least one of a weighted sum-rate and max-min rate objective into two or more sub-problems by introducing at least one slack variable. The two or more sub-problems are iterated on a computer readable storage medium to provide at least one transmit precoder for each transmitter.

Abstract: A wireless communications device operates in a system where communications resources may be used by multiple devices concurrently. A device, with an acquired set of recurring time intervals, selects, e.g., pseudo-randomly, an interval or intervals to be used as a combined data transmission and channel measurement time interval. The other time intervals in its set are to be used as data transmission time intervals. The combined use type interval facilitates the measurement of interference on the device's channel while still allowing the device to transmit some data during the interval. A combined use interval includes a first portion for data transmission and a second portion for channel measurement. In some embodiments, the first portion is fixed size and the second portion occurs at the very end of the interval. In some embodiments, the duration of the first portion is varied over time such that the channel measurement start time varies.
