Embodiment Construction

[0029] In the following detailed description, numerous specific details are set forth in order to provide a thorough understanding of the teachings of the described embodiments. Note, however, that the invention may be practiced without some of these specific details.

[0030] figure 1 The problem of sending control reports on the data channel 18 is shown. A base station 10 is located in a cell 12 . Mobile units such as UE 14 are movable throughout unit 12 and can communicate with base station 10 . As can be seen, UE 14A is positioned close to the edge of cell 12 and UE 14B is positioned close to base station 10 . Various parameters—including, for example, the distance between the UE 14 and the base station as well as the nature of the terrain of each UE 14 and the speed of each UE 14 relative to the base station 10—affect the performance of the wireless transmission channel (or simply, the "wireless channel"). quality.

[0031] Each UE 14 sends and receives various type...

Abstract

A control channel encoder includes a determiner configured to determine a current value of K for encoding control signals of a length M, wherein K is a function of a code rate for a data channel. A table generator is configured to, if K is greater than a predetermined threshold, generate a repeated matrix from a fixed block encoding matrix by variably repeating rows from said fixed block encoding matrix. A puncturer is configured to, if K is less than the predetermined threshold, puncture the fixed block encoding matrix to reduce a size of the fixed block encoding matrix. A block encoder is configured to utilize said repeated matrix, to encode M input control bits as K encoded control bits, by generating an encoded payload from said repeated matrix.
