application example 1

[0086] In the LTE Advance system, the schematic diagram of its network layout can be found in figure 2 , there is an S1 interface between the core network and the base station (macro base station), and there is an X2 interface between adjacent base stations; the home base station can be directly connected to the core network, or can be connected to the core network through the home base station gateway. There is no X2 interface between the home base station and the macro base station. The UE is located in a carrier aggregation cell managed by the macro base station and is in an idle state. The component carriers included in the carrier aggregation cell are three consecutive 20MHz component carriers within the frequency band 1 (Band1, uplink UL 1920-1980MHz, downlink DL 2110-2170MHz). These three carriers all send system messages and paging messages.

[0087] At a certain moment, the UE initiates random access on component carriers (UL 1920-1940, DL 2110-2130), and successfu...

Abstract

The invention discloses a method for processing measurement configuration in carrier aggregation. The method comprises the following steps that: user equipment (UE) which is in a connected state in a cell of the carrier aggregation governed by a base station acquires one or more configured measurement reference component carriers; the UE receives the measurement configuration transmitted by the base station, wherein the measurement configuration comprises a measurement events applied to the one or more measurement reference component carriers; and the UE measures according to the measurement configuration. The invention also discloses a method for processing the measurement configuration in the carrier aggregation. The method comprises the following step of: after the UE in the connected state in the cell of the carrier aggregation governed by the base station receives the measurement configuration, determining the measurement reference component carrier corresponding to the measurement event in the measurement configuration and evaluating a measurement object meeting an event triggering condition. The method has the advantages of eliminating different meanings of a service cell in the carrier aggregation, realizing compatibility with the measurement configuration in the conventional protocol and meeting the requirement of mobility in the carrier aggregation.

Description

technical field [0001] The present invention relates to the field of mobile communication, in particular to a method for processing measurement configuration in carrier aggregation (CA for short). Background technique [0002] In a mobile communication system, in order to meet mobility requirements, after a user equipment (UE) establishes a connection with the network in a certain cell, the UE still needs to measure the signal quality of its serving cell and neighboring cells, so as to Select a suitable cell for handover. Taking EUTRAN (Evolved Universal Terrestrial Radio Access Network, Evolved Global Terrestrial Radio Access Network) as an example, the specific process of UE measurement in the connected state is: the network side sends a measurement control message to the UE, wherein the measurement control message includes Measurement identity (measurement identity, referred to as MID), event type, measurement object, and attributes to be measured; UE performs parameter ...
