Determination of pre-coding matrix indicators for spatial multiplexing in a mobile communications system. |
摘要 |
A pre-coding matrix is determined in an OFDMA, multiple transmit antenna communication system having a number of sub-carriers grouped into a number, M, of resource blocks. This involves determining a frequency selectivity of a channel through which received signals have propagated. A number N of selected resource blocks is then determined as a function of the frequency selectivity the N selected resource blocks being those for which pre-coding matrices will be determined, wherein N<M. The pre-coding matrices are then determined for the N selected resource blocks. Pre-coding matrices for a remaining M−N of the M resource blocks are determined by means of interpolation applied to the N pre-coding matrices determined for the N selected resource blocks. |
