Multiplexing system, method for sharing control channel resource and reception equipment thereof

Abstract

The invention discloses a multiplexing system, method, and receiving device of multi-carrier communication system sharing control channel resources. The method consists of the steps: A. the control signal of different users in the district divided into at least two groups, the frequency resources of the sharing control channel is divided into at least two frequency resources blocks, the frequency resource blocks are sorted according to certain sequence, and the frequency resources of the first position quadrates with the first position frequency resources of at least one neighboring district; B. a frequency resources block is distributed to each control signal group. The invention distributes the frequency resources of the sharing control signal in the same district to the different control signal groups, so according to the actual situation the different users in the district can be managed effectively, the order of priority of the resource distribution can be determined, the users who has need can get the resource of relatively high priority, and flexible communication management can be realized.

Description

technical field [0001] The present invention relates to a communication system, a method and a receiving device thereof, in particular to a multiplexing system, a method and a receiving device thereof in which a multi-carrier communication system shares control channel resources. Background technique [0002] Wireless communication systems are usually distinguished by geographical regions, such as cellular wireless communication systems, to achieve frequency reuse and increase the capacity of the wireless communication system. Each communication area in a wireless communication system may be referred to as a cell. When frequency resources are allocated using a standard with a reuse factor of 1, different cells use the same frequency, so signals from different cells working on the same frequency will interfere with each other. [0003] At present, a multi-carrier system based on OFDM (Orthogonal Frequency Division Multiplexing, Orthogonal Frequency Division Multiplexing) tec...

AI Technical Summary

Problems solved by technology

Especially for users in the cell edge area, when the frequency reuse factor of the cell is 1, the received control channel signal will be interfered by the control channel of the adjacent cell, thereby reducing the accuracy of demodulation of the control signaling of the cell, resulting in Difficulty communicating with users

[0007] In addition, the control signaling modulation and coding methods of different users in the cell are different, resulting in a large amount of signaling traffic and wasting communication resources; and users cannot use the same modulation and coding method due to different environments, otherwise a certain Some users with poor channel conditions cannot receive control signaling
