Problems solved by technology

However, in carrier aggregation, since the UE can communicate with the source base station through multiple cells at the same time after entering the connected state, if the UE still reports in the LTE way, since the UE cannot predict which component carriers the base station will configure for the UE for aggregation, Therefore, in order to take the overall situation into consideration and avoid that the base station is not configured when the measurement interval is required, the UE will largely need the measurement interval to perform measurements for all frequency bands, which will cause the base station to configure the measurement interval when the UE does not need the measurement interval. According to the definition of the measurement interval, the base station will not schedule the UE within the time specified by the measurement interval, and the base station can completely schedule the UE during this period, so unnecessary measurement intervals will undoubtedly cause a great waste of resources

Embodiment 1

[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.

[0052] The base station requests the UE to report capability information, and the UE reports the following carrier aggregation capability information according to its own capabilities: it supports up to two ca...

Embodiment 2

[0075]In the EUTRAN system, the center frequency point of the UE is in the connected state after the cell1 on F1 completes the RRC establishment process, and F1 belongs to frequency band 1. Figure 5 It is a schematic diagram of the structure of the UE in Embodiment 2 of the present invention, such as Figure 4 As shown, the UE has three separate receivers, each supporting a bandwidth of 20M, and the UE uses receiver 1 by default to process the data communication of cell1.

[0076] The base station requests the UE to report capability information, and the UE reports the following carrier aggregation capability information according to its own capabilities: Up to three carriers are supported for aggregation, and the first frequency band and the second and third frequency bands are not in order, only describing that the UE supports the first Carrier aggregation is performed on the first frequency band and the frequencies on the second and third frequency bands. In Embodiment 2, ...

Embodiment 3

[0105] In the EUTRAN system, the center frequency point of the UE is in the connected state after the cell1 on F1 completes the RRC establishment process, and F1 belongs to frequency band 1. Figure 6 It is a schematic structural diagram of UE in Embodiment 3 of the present invention, such as Figure 5 As shown, the UE has a single receiver that supports a bandwidth of 40M.

[0106] The base station requests the UE to report the capability information, and the UE reports the carrier aggregation capability information according to its own capability: at most one carrier is supported for aggregation, and the maximum supported bandwidth is 40MHz. The carrier aggregation capability information reported by the UE can be shown in Table 3.1:

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...
