Problems solved by technology

When the same-frequency heterogeneous deployment is introduced, a UE in a connected state on a certain carrier frequency may measure a different frequency, and the different frequency is just used in the above-mentioned same-frequency heterogeneous deployment. A frame may be all high-interference subframes, or it may be a mixture of high-interference subframes and low-interference subframes corresponding to ABS. The existing measurement technology cannot configure appropriate inter-frequency measurement parameters to ensure measurement in this case need

Embodiment 1

[0066] In order to solve the problem that existing inter-frequency measurement technology cannot configure inter-frequency measurement parameters based on ABS information to ensure measurement requirements, this embodiment provides a measurement method, see Figure 4 ,include:

[0067] 401: The serving cell of the user equipment UE obtains the relevant information of the almost blank subframe ABS of the offending cell;

[0068] 402: The serving cell configures inter-frequency measurement configuration information according to the relevant information of the ABS, and sends it to the UE, so that the UE performs inter-frequency measurement on the victim cell according to the inter-frequency measurement configuration information;

[0069] Wherein, the carrier frequency of the serving cell is different from that of the victim cell, and the carrier frequency of the victim cell is the same as that of the offending cell.

[0070] In this embodiment, the information related to the ABS...

Embodiment 2

[0073] In order to solve the problem that existing inter-frequency measurement technology cannot configure inter-frequency measurement parameters based on ABS information to ensure measurement requirements, this embodiment provides a measurement method, see Figure 5 ,include:

[0074] 501: The serving cell of the user equipment UE obtains the relevant information of the almost blank subframe ABS of the offending cell.

[0075] Specifically, any of the following methods can be used:

[0076] The serving cell of the UE receives the ABS information of the offending cell sent by the offending cell;

[0077] The serving cell of the UE receives the low-interference subframe information of the victim cell sent by the victim cell;

[0078] The serving cell of the UE receives the ABS information of the offending cell or the low-interference subframe information of the victim cell sent by the OAM (Operation Administration and Maintenance, operation, management, operation and maintena...

Embodiment 3

[0109] In order to ensure the validity of the synchronization signal, that is, to ensure that the UE has a synchronization signal measurable within the Gap length time, on the basis of Embodiment 1 or 2, the step of setting the ABS subframe by the offending cell according to the synchronization type of the victim cell can also be added, To ensure that the synchronization signal of the victim cell is a low-interference subframe, see Figure 7 , the present embodiment provides a measurement method, including:

[0110] 701: The offending cell configures an ABS subframe according to the synchronization type of the victim cell.

[0111] Specifically, configure as follows:

[0112] If the victim cell is an FDD (Frequency Division Duplexing, Frequency Division Duplexing) system, the offending cell configures the subframes of the offending cell corresponding to subframes No. 0 and / or No. 5 in a radio frame of the victim cell as ABS subframes ;

[0113] Or, if the victimized cell is...

Abstract

The invention discloses a measurement method, a base station and user equipment, belonging to the technical field of communication. The method includes: the serving cell of the user equipment UE obtains the relevant information of the almost blank subframe ABS of the offending cell; the serving cell configures inter-frequency measurement configuration information according to the relevant information of the ABS, and sends it to the UE, so that The UE performs inter-frequency measurement on the victim cell according to the inter-frequency measurement configuration information; wherein, the carrier frequency of the serving cell is different from that of the victim cell. In the present invention, the serving cell configures inter-frequency measurement parameters according to the ABS related information of the offending cell, and sends them to the UE for inter-frequency measurement on the victim cell, which solves the problem that the existing inter-frequency measurement technology cannot configure inter-frequency measurement parameters based on the ABS information problem, thereby ensuring the need for inter-frequency measurement.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a measurement method, base station and user equipment. Background technique [0002] At present, small base stations such as Pico (miniature base station), HeNB (home base station), Femto (miniature base station), and Relay (medium base station) can be placed within the coverage of LTE (Long Term Evolution, long-term evolution) Macro eNB (macro base station). Following the base station) and other wireless access points, the UE (User Equipment) is under the dual coverage of Macro eNB and small base station. The maximum capacity that this system can obtain is the sum of the capacity of Macro eNB and small base station. The entire communication system Compared with the previous traditional LTE macro base station network, it has higher capacity. In scenarios such as office buildings, shopping malls, and campus networks, the heterogeneous deployment of these small base...
