摘要： A method and a circuit for generating cyclic redundancy checks. The method calculates a plurality of cyclic redundancy checks for a transport block with a plurality of information bits. At least one cyclic redundancy check among the plurality of cyclic redundancy checks is calculated based on a subset of information bits, and at least one information bit among the plurality of information bits is not within said subset of the information bits. In addition, a transport block cyclic redundancy check may be calculated based on all the information bits.

摘要： A system, a receiver apparatus, a transmitter apparatus and a method for inter-user interference cancellation when simultaneous transmissions from two wireless users to the same base station are repeated using the same time-frequency resource. The percentage of interference cancellation is pre-set and phase shifts of the first and repeated transmitted symbols for each mobile user are determined in accordance with this pre-set percentage. The receiver uses a pre-determined technique for estimating the received symbols in accordance with the pre-set percentage and phase shifts.

摘要： Methods and apparatus for transmitting Asynchronous Hybrid Automatic Repeat reQuest (ARQ) process identities in a wireless communication system. A linking scheme is established between at least two sets of process identities of two respective corresponding codewords. When a first process identity is selected from among a first set of process identities of a first codeword, a second process identity may be derived in dependence upon the first process identity and the established linking scheme. Finally, a first packet from the first codeword is transmitted using a first transmission channel indicated by the first process identity, and a second packet is transmitted from the second codeword using a second transmission channel indicated by the second process identity. In addition, a control message including only the first process identity is transmitted.
