Patent ID: 8917677

Claim:
A base station, comprising: transmit path circuitry configured to transmit a downlink frame to a first mobile station, the downlink frame comprising time-frequency resource elements allocated in a plurality of physical resource blocks (PRBs), wherein the base station is configured to selectively operate in either a frequency division duplex mode or a time division duplex mode, and to enable PRB bundling when operating in the frequency division duplexing mode and disable the PRB bundling when operating in the time division duplexing mode, wherein the transmit path circuitry is configured to transmit, when the PRB bundling is enabled, the plurality of physical resource blocks from physical resource blocks allocated to the first mobile station using bundles having a bundle size that is a function of system bandwidth, and wherein the transmit path circuitry is configured to use a same precoder for all physical resource blocks in a same bundle.
