The method includes: determining reserved resources; determining A/N information that needs to be transmitted; and determining that the number of transmission resources is N (N is an integer greater than or equal to 2) and corresponding modulation symbols according to the number of the reserved resources and the A/N information that needs to be transmitted; and transmitting multiple A/N information by transmitting the modulation symbols by using the transmission resources. By transmitting multiple A/N information, a downlink frequency band where an error occurs can be correctly located. The A/N information includes acknowledgement (ACK) information, negative acknowledgement (NACK) information or Discontinuous Transmission (DTX) state information.

摘要： A method and an apparatus of symbol interleaving are provided. A sequence S(i) is transformed to generate a symbol interleaving sequence. A numerical value of the sequence S(i) is corresponding to a serial number of a channel element (CE). The symbol interleaving sequence may also be obtained based on a Costas sequence. Therefore, the number of symbol groups in one CE that are mapped to the same physical resource position by different cells is effectively reduced, so that the effect of interference randomization between the cells is improved, the influence of the interference between the cells on the system performance is lowered, and the generation of the symbol interleaving sequence is simplified.

摘要： A resource allocation method for MIMO (multi-input multi-output-OFDM (orthogonal frequency-division multiplex) of multi-user access systems includes A) for each sub-carrier or group of sub-carriers of OFDM, grouping signature vectors of users at a time period according to correlations of the signature vectors; B) from the grouping results, selecting the signature vectors according to a scheduling rule; assigning the sub-carrier frequency and time resource to users of which simultaneously the selected signature vectors have low correlations; and assigning spatial resource to the users corresponding to the selected signature vectors. By minimizing the spatial co-channel interference to an acceptable low level, the complexity significantly in the joint multi-user optimization is reduced.
