Embodiment Construction

[0034] In the embodiment of the present invention, the network side sends the determined cell identity of each cell in the basic set of measurement cells to the terminal, determines the set of participating CoMP cells from the basic set of measurement cells, and determines the index information corresponding to each cell identity in the set of participating CoMP cells , and send the determined index information to the terminal, instructing the terminal to determine the cell identity participating in CoMP from the basic set of measurement cells according to the received index information, wherein the number of bits occupied by each index information is smaller than the number of bits occupied by each cell identity. Since only the index information of each cell participating in CoMP needs to be notified to the terminal, signaling overhead is reduced and utilization of system resources is improved.

[0035] If the basic set of measurement cells is a Measurement Set (measurement se...

Abstract

The invention relates to the wireless communication technology, in particular to a method, a system and a device for determining CoMP participating cells for solving the problem of large amount of signaling overhead required for informing a user terminal of cell identifier of each cell in the cells participating in the CoMP when an LTE-A system performs the CoMP in the prior art. The method of the embodiment of the invention comprises the following steps of: sending the cell identifier of each cell in a determined measurement cell basic set to a terminal through a network side, determining a CoMP participating cell set in the measurement cell basic set, determining index information corresponding to each cell identifier in the CoMP participating cell set, and sending the determined index information to the terminal to indicate the terminal to determine CoMP participating cell identifier from the measurement cell basic set according to the received index information. The method of the embodiment of the invention can reduce the signaling overhead and improve the utilization rate of system resources.

Description

technical field [0001] The present invention relates to wireless communication technology, in particular to a method, system and device for determining a cell participating in CoMP (Coordinated multi-point, coordinated multi-point). Background technique [0002] In an LTE-A (Long Term Evolution-Advanced, long-term evolution upgrade) system, a CoMP sending and receiving technology can be used to increase coverage of high data rates, thereby improving cell edge throughput and / or increasing system throughput. [0003] The so-called CoMP means that multiple geographically separated transmission points (that is, different cells belonging to one or more evolved base stations) cooperate to participate in sending and receiving data for a user equipment (UE). [0004] The CoMP technology is divided into downlink CoMP and uplink CoMP. Downlink CoMP means that the user equipment needs to measure or process downlink signals or data of multiple cells; uplink CoMP means that multiple cel...
