Method and apparatus for encoding feedback signal

摘要

A method and apparatus for encoding feedback signal is provided. The method includes: encoding feedback signals of three carriers to output a bit sequence; and transmitting the bit sequence on a High Speed-Dedicated Physical Control Channel (HS-DPCCH). The encoding the feedback signals of the three carriers may specifically include: mapping the feedback signals of the three carriers into a codeword, in which the codeword can be selected from a codebook, and codewords in the codebook satisfy a particular code distance relationship. The method for jointly encoding feedback signals of three carriers in a Ternary Cell (TC) mode is provided. Feedback signals are transmitted over a single code channel. Therefore, power overhead is reduced, and system performance is improved.

1. A method for transmission of feedback information, comprising:
transmitting data to a user equipment (UE) on three carriers simultaneously; receiving encoded feedback information of the three carriers from the UE in response to reception of the data; wherein the encoded feedback information of the three carriers is encoded Hybrid Automatic Repeat Request-Acknowledgement (HARQ-ACK) signals of the three carriers; wherein the encoded HARQ-ACK signals of the three carriers is a codeword into which HARQ-ACK signals of the three carriers are mapped according to the following mapping relationship between the HARQ-ACK signals of the three carriers and the codeword:ACK-DTX-DTX1111111111NACK-DTX-DTX0000000000DTX-ACK-DTX1111100000DTX-NACK-DTX0000011111DTX-DTX-ACK1100011000DTX-DTX-NACK0011100111ACK-ACK-DTX1010101010ACK-NACK-DTX1100110011NACK-ACK-DTX0011001100NACK-NACK-DTX0101010101ACK-DTX-ACK1011011001ACK-DTX-NACK0101101001NACK-DTX-ACK0001111010NACK-DTX-NACK1001110100DTX-ACK-ACK0111010010DTX-ACK-NACK1010010110DTX-NACK-ACK0110001011DTX-NACK-NACK0000101011ACK-ACK-ACK1101001110ACK-ACK-NACK0110111100ACK-NACK-ACK1001000011ACK-NACK-NACK0010110001NACK-ACK-ACK1110000101NACK-ACK-NACK0100100110NACK-NACK-ACK1000101101NACK-NACK-NACK1111010100 wherein DTX represents discontinuous transmission, ACK represents acknowledgement, NACK represents negative acknowledgement.
