Abstract: A method is provided for selecting a precoding matrix to be used in an MIMO communication system. The MIMO communication system includes a transmitter, a receiver and a communication channel. The precoding matrix is used by the transmitter to precode codewords to be transmitted to the receiver over the communication channel. At the receiver, an optimum precoding matrix within a codebook of precoding matrices is determined based on a metric related to the power of received signal layers. An indication is then fed back from the receiver to the transmitter to enable the transmitter to select the optimum precoding matrix from the codebook.

Abstract: Downlink and uplink communication resources to ensure network coverage and satisfy assigned traffic requirements in a communication network are allocated by setting a given balance of downlink and uplink communication resources while leaving a part of downlink and uplink communication resources remaining to be allocated. Downlink cell radius and uplink cell radius values are then determined which ensure network coverage with the resources as previously allocated. An effective cell radius is then selected as the smaller of the downlink and uplink cell radius and then a first check is made as to whether the effective cell radius selected satisfies the assigned traffic requirements. If not, the effective cell radius is updated. If so, a further check may be made as whether the resources remaining to be allocated for downlink and uplink have a difference in excess of a given amount.
