    摘要： Systems and methods are provided for implementing error identification and evaluation for a Reed-Solomon (RS) error-correction code (ECC) system. The BMA algorithm and/or list decoding may produce one or more error locator polynomials that are related to a decision-codeword. An accelerated Chien search can be used to more quickly evaluate the one or more error locator polynomial. If the accelerated Chien search identifies a valid error locator polynomial, a normal Chien search can be used to identify error locations, and Forney's algorithm or an equivalent technique can be used to evaluate the error values. A RS ECC decoder can include a computation circuit that evaluates an error locator polynomial or an error evaluator polynomial. The computation circuit can include computation components that receive the coefficients of the polynomials.

The method includes: when two transport blocks/codewords are transmitted in the PUSCH, mapping uplink control signaling to the layer corresponding to one of the two transport blocks/codewords to transmit. The present invention also discloses an apparatus for transmitting uplink control signaling in the PUSCH. The apparatus includes: a mapping unit, used for mapping uplink control signaling to the layer corresponding to one of two transport blocks/codewords when the two transport blocks/codewords are transmitted in the PUSCH; and a transmission unit, used for transmitting the uplink control signaling. The present invention effectively solves the problem of transmitting uplink control signaling in the PUSCH when the PUSCH uses spatial multiplexing in an LTE-A system.
