Abstract

A Joint coding method and a coding device which are used in physical control channel reuse, before multi-channel control signaling is reused and channel coded by the method, wherein the 2-bit signaling data using generated the G-matrix of one control signaling is subcode coded; the first 3*M column or the last 3*M column of the G is corresponding column of the M-th G<23>, The other X column is composition of the X column of the G<23>; the first 2 columns or the last 2 columns of the G<23> are corresponding column of 2-order unit matrixes, various elements of the Last column is 1; 0<=X<= 3, M>=1. Using the subcode encoder and the subcode coding method of the invention, can ensure that the smallest hamming distance of output code inter-word is the largest, and different generator polynomials corresponded with different values of output code words requirement can be obtained by a simple repeat of unified generator polynomial G<23>, thus having the advantage of achieving simply.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to a joint coding method and a coding device in multiplexing physical control channels in a broadband wireless system. Background technique [0002] In a wireless communication system, generally there are multiple kinds of uplink physical control signaling. When the uplink control signaling is not sent together with the data, they will be sent on a dedicated physical uplink control channel. Usually, the bit error performance requirements of these various control signalings are different. When a user equipment (User Equipment, UE for short) needs to transmit uplink control signaling in different formats simultaneously on the same subframe, this involves the multiplexing of uplink control channels in multiple formats. [0003] A commonly used multiplexing scheme is to adopt a joint coding method, and FIG. 1 shows a schematic diagram of implementing multiplexing of a control chann...
