    摘要: A method from transmitting data via multiple antennas. In this method, four information bits to be transmitted are multiplexed by using either one of a code division multiplexing scheme or a second code division multiplexing scheme combined with a real and imaginary multiplexing scheme, to generate a code division multiplexed symbol including four vectors. Then, the code division multiplexed symbol is repeatedly transmitted by alternatively applying two transmit diversity schemes via four transmission antennas.

    摘要: A mobile station capable of communicating via an uplink transmission to at least one base station in a Multiple Input Multiple Output wireless network can map codewords to a plurality of layers. The mobile station includes a plurality of transmit antenna and a controller coupled to the plurality of transmit antenna. The controller is configured to map at least one codeword to a plurality of layers. The codeword includes a plurality of code blocks. The controller is configured to generate the plurality of code blocks from a transport block such that the number of code blocks generated correspond to an integer multiple of a number the plurality of layers.

    摘要: A quantization method of transmission of channel quality information (CQI) includes measuring two measurements SINRs and calculating a difference (i.e., Delta SINR) between the two measurements of the SINRs; determining a CQIbase (base channel quality information) based on one of the two measurements SINRs and a known quantization table for the CQIbase, and simultaneously receiving cell-specific or UE-specific parameters transmitted from a base station and configuring a quantization table defining a mapping method of CQIdelta (delta channel quality information) and the Delta SINR and determining the CQIdelta based on the obtained Delta SINR and the configured quantization table; and transmitting the resulting CQIdelta and CQIbase.
