Problems solved by technology

However, the only information used to distinguish measurement objects in the same-frequency measurement object list is the parameter ID. In a multi-carrier system, the parameter ID in the same-frequency measurement object list may have the same situation, and there is no frequency point information, so it

Embodiment Construction

[0019] The core idea of ​​the present invention is that in view of the ambiguity of the same-frequency and different-frequency measurements in the existing multi-carrier situation, the serving cell and its adjacent cells are distinguished according to the frequency of the main carrier and the cell parameter ID (Cell Parameter ID). Based on the original air interface measurement of CCSA, a new measurement series is added to the measurement control (MEASUREMENT CONTROL) message and measurement control system information (Measurement control system information). In this series of measurements, the main carrier frequency and cell identification code are used The Cell Parameter ID distinguishes the measurement cells, and realizes the same-frequency and different-frequency measurements without distinguishing the relationship between the same-frequency or different-frequency adjacent cells.

Abstract

The utility model discloses a measurement method for same frequency and pilot frequency in a multi-carrier wave wireless communication system, comprising the following steps: a new measure series are added in the measure control information, in the measure series, a plurality of measure cells are identified by the main carrier frequency and the Cell Parameter ID. The measure series comprises a P-CCPCH RSCP measurement entity and a ISCP measurement entity of a user terminal based on the neighborhood relation. The utility model has advantages of providing a measurement method for a multi-carrier frequency system serving cell and neighborhood P-CCPCH RSCP and ISCP, eliminating the polysemy of the prior same frequency or pilot frequency, meanwhile furthest being compatible with the content of 3GPP and CCSA on protocol and concept definition.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to a co-frequency and different-frequency correlation measurement method in a multi-carrier wireless communication system. Background technique [0002] In a multi-carrier Time Division Synchronization Code Division Multiple Access (TD-SCDMA, Time-Division Synchronization Code Division Multiple Access) system, the definition of Intra-frequency Measurements and Inter-frequency Measurements is the same as that of a single frequency point The systems are very different. In a single-carrier system, there is a one-to-one correspondence between a carrier and a cell, so that the actual bearer of communication resources and the bearer of measurement resources are both on the same carrier frequency. The difference between the same frequency and different frequency is not only based on the cell level, but also the same frequency and different frequency cells are mutually exclu...
