Mobile measurement method for multi-carrier networking, network equipment and user equipment

Abstract

A method, network side device and user equipment for mobile measurement in a multi-carrier network. The network side device configures the User Equipment (UE) for an intra-frequency measurement of a primary carrier and for an intra-frequency measurement of a secondary carrier, so that the UE acquires a monitoring set corresponding to the primary carrier on the basis of the intra-frequency measurement configuration of the primary carrier, acquires a monitoring set corresponding to the secondary carrier on the basis of the intra-frequency measurement configuration of the secondary carrier, initiates the intra-frequency measurement of the primary carrier of a cell set containing the monitoring set corresponding to the primary carrier and a preset active set corresponding to the primary carrier, generates an intra-frequency measurement event of the primary carrier, initiates the intra-frequency measurement of the secondary carrier of a cell set containing the monitoring set corresponding to the secondary carrier, and generates an intra-frequency measurement event of the secondary carrier; and the network side device acquires the intra-frequency measurement events of the primary carrier and the secondary carrier reported by the UE on the primary carrier. With the method and device provided in the present invention, network complexity can be reduced.

Description

technical field [0001] The present invention relates to communication technology, in particular to a mobile measurement method for multi-carrier networking, network side equipment and user equipment. Background technique [0002] In a Wide-band Code Division Multiple Access (WCDMA) system, a heterogeneous network (Heterogeneous, Hetnet for short) may be used. figure 1 It is a schematic diagram of the structure of the heterogeneous network. Such as figure 1 As shown, the network includes a macro station (Macro Node B) with a large coverage area and a micro station (Pico Node B) with a small coverage area. The downlink coverage of a cell is determined by the downlink transmit power of the cell. figure 1 In , the coverage area of ​​the macro station is represented by F2, the coverage area of ​​the micro station is represented by F1, and the coverage areas of the macro station and the micro station have overlapping areas. In a heterogeneous network, it is necessary to know th...

Problems solved by technology

[0004] Using the above-mentioned existing mobile measurement method for multi-carrier networking, since two active sets are established, the cells in the active set of the primary carrier and the cells in the active set of the secondary carrier need mutually independent downlink and uplink , the number of uplink carriers required by this scheme is large, and the network complexity is high
