Problems solved by technology

[0012] The disadvantage of the existing technology is that due to the introduction of the CA technology, multiple carriers may be continuously or discontinuously contained in the same cell. However, under the same LTE-A cell, the signals measured by the UE on other component carriers may It is mistaken by the UE as coming from other cells, resulting in unnecessary measurement behavior and subsequent handover behavior in this cell

Embodiment Construction

[0046] The specific embodiments of the present invention will be described below with reference to the accompanying drawings.

[0047]When the present invention is implemented, for the same LTE-A cell, in the measurement configuration related to the serving cell, the physical layer ID of the cell on other component carriers other than the component carrier that establishes a connection with the UE is blacklisted (blacklist). list), thereby avoiding unnecessary measurement behavior by the UE.

[0048] image 3 It is a schematic diagram of the implementation flow of the cell measurement method for UE. As shown in the figure, the following steps may be included when performing cell measurement:

[0049] Step 301: Determine the component carrier in the cell, and the component carrier used by the UE to establish a connection with the cell;

[0050] Step 302: List the physical layer ID of the cell on the component carriers other than the component carrier used by the UE to establi...

Abstract

The invention discloses a method and equipment for measuring the cell member carriers in a long-term evolving and upgrading system. The method comprises the following steps of: determining member carriers in a cell and the member carriers used for establishing the connection between the user equipment and the cell; listing the local cell physical layer ID on the member carriers except the member carriers used for establishing a connection between the user equipment and the cell in a blacklist for the measurement of allocation domains in specific control signals; updating the blacklist in the local measurement of allocation information by the user equipment according to the blacklist for the measurement of the allocation domains in the specific control signals; and measuring the member carriers according to the local measurement of allocation information. By using the method and the equipment, unnecessary measurements and succeeding possible and unnecessary switches can be avoided, theuser equipment is prevented from being switched to other carriers in the cell, and unnecessary measurement expenses for the user equipment are saved.

Description

technical field [0001] The present invention relates to a long-term evolution multi-carrier upgrade system, in particular to a method and equipment for measuring cell component carriers in the long-term evolution upgrade system. Background technique [0002] 1) Introduction to carrier aggregation technology in LTE-A (Long Term Evolution-Advanced, Long Term Evolution-A). [0003] In the LTE-Advanced system, CA (Carrier Aggregation, carrier aggregation) technology is introduced. [0004] figure 1 It is a schematic diagram of the relationship between the carrier and the bandwidth of a cell in LTE. As shown in the figure, in the LTE system, there can only be one carrier in a cell, and the maximum bandwidth is 20Mhz. [0005] In LTE-A, the peak rate of the system is greatly improved compared with LTE, and it is required to reach 1Gbps downlink and 500Mbps uplink. The 20Mhz bandwidth in LTE can no longer meet this requirement. Therefore, the CA technology is introduced into the ...
