Method for reporting measurement capability, and UE (User Equipment)

Abstract

The invention discloses a method for reporting the measurement capability. UE (User Equipment) reports the self measurement capability to a base station. The measurement capability lies in that: the UE works under a frequency band or a carrier aggregation scene; the UE executes the capability whether a measurement interval is needed in the measurement process of a pilot frequency inter-system on each frequency band; and after acquiring the measurement capability of the UE, the base station determines whether to allocate the measurement interval to the UE according to the frequency band to which a carrier allocated by the UE and used for aggregation belongs, the frequency band to which the carrier frequency of a measurement object of the currently-allocated measurement task belongs, and the measurement capability of the UE. The invention further correspondingly discloses the UE. According to the method for reporting the measurement capability and the UE, the measurement interval can be not allocated to the UE if unnecessary, thus the influence of the pilot frequency inter-system measurement on business can be reduced, and resource waste possibly caused by measurement of the UE under the carrier aggregation scene is avoided.

Description

technical field

[0001] The present invention relates to the technical field of digital mobile communication, in particular to a method for reporting measurement capabilities and user equipment (User Equipment, UE). Background technique

[0002] In cellular mobile communication systems, cell reselection and handover are important functions. In order to realize cell reselection smoothly, the UE needs to measure the signal quality of different cells so as to select a suitable cell to camp on. After the UE establishes a connection with the network in a certain cell, the UE still needs to measure the signal quality of its neighboring cells in order to select a suitable cell for handover and meet mobility requirements.

[0003] The specific process for the UE to measure in the connected state includes: the network side sends a measurement control message to the UE, wherein the measurement control message includes a measurement identity (Measurement Identity, MID), a measurement o...

[0051] In Embodiment 1 of the present invention, the schematic flow chart of UE reporting measurement capability and base station performing measurement configuration is as follows Figure 4 shown. In this embodiment, the UE in the E-UTRAN system is in the connected state after the center frequency point of cell1 on F1 completes the RRC establishment process, F1 belongs to frequency band 1, and the UE has two separate receivers, each supporting a bandwidth of 20M. The UE is constructed as figure 2 As shown, receiver 1 supports working on frequency bands 1 / 2 / 3, and receiver 2 supports working on frequency bands 1 / 4 / 5. The following embodiments are based on figure 2 UE shown. Here, the UE uses the receiver 1 to process the data communication of the cell1 by default.
