METHOD OF ALLOCATING RESOURCES FOR TRANSMITTING UPLINK SIGNAL IN MIMO WIRELESS COMMUNICATION SYSTEM AND APPARATUS THEREOF

摘要

A method and terminal are described for allocating resources for transmitting a signal in a multiple-input multiple-output (MIMO) wireless communication system. An uplink signal is transmitted using L layers at a terminal in a multiple-input multiple-output (MIMO) wireless communication system. Modulation symbols are generated by modulating output bit sequences of an interleaver matrix by a unit of log2Q bits, where Q is a modulation order. Each of the output bit sequences has a size of L·log2Q bits. The modulation symbols are mapped to the L layers and transmitted by using the L layers. The output bit sequences are generated by reading out entries of the interleaver matrix, column by column.

1. A method for performing a channel interleaving of an uplink signal to be transmitted via L layers at a terminal in a Multiple-Input Multiple-Output (MIMO) wireless communication system, the method comprising:
writing input vector sequences into entries of a matrix for the channel interleaving row by row; and generating output bit sequences by reading out the entries of the matrix column by column, wherein each of the entries comprise L·log2Q rows, where Q is a modulation order.
