Abstract

The invention relates to a carrier channel information measurement and feedback method of a long-term evolution multi-carrier system. User equipment measures a pilot signal of a received first carrier, obtains the channel information of the first carrier and feeds back to a base station; the user equipment converts a receiving frequency point according to a communication protocol specification ora high-level signaling transmitted by the base station and receives and measures a pilot signal of a second carrier corresponding to the receiving frequency point; and the user equipment feeds back the channel information of the second carrier obtained by measuring the pilot signal of the second carrier to the base station. The invention can realize the channel information feedback of the currentused carrier and an unused carrier in a multi-carrier system, is beneficial to the modulation coding way selection and the frequency resource dispatch of a base station system and the user equipment in the process of data transmission and embodies the frequency selective gain of the long-term evolution multi-carrier system to the greatest extent. The invention also provides a carrier selection system/method of the long-term evolution multi-carrier system, the base station and the user equipment.

Description

technical field [0001] The invention relates to a long-term evolution multi-carrier system, in particular to a system and method for measuring and feeding back wave channel information of the long-term evolution multi-carrier system. Background technique [0002] In a long-term evolution multi-carrier system, a larger system bandwidth needs to be supported than in a long-term evolution (LTE) system. Since spectrum resources are limited, multiple carrier aggregation techniques need to be used when allocating spectrum resources. And according to specific conditions, it is set that multiple carriers are continuously or discretely distributed on the entire spectrum resource, and the characteristics of each carrier are compatible with the characteristics of the existing LTE technology. That is, each carrier is equivalent to the system bandwidth of the existing LTE system, and multiple carriers constitute the system bandwidth of the long term evolution multi-carrier system. Acco...
