Embodiment 1

[0087] like image 3 As shown, the inter-frequency measurement configuration method in this embodiment mainly includes the following steps:

[0088] Step 301, the base station configures the same measurement interval offset for each different-frequency frequency point, the measurement subframe pattern and the measurement subframe cell list on each different-frequency frequency point for the user equipment, and sends them to the user equipment;

[0089] Step 302, according to the received inter-frequency measurement configuration information, the user equipment measures the given cell in the corresponding measurement subframe cell list at the measurement interval starting from the measurement interval offset and the subframe position corresponding to the intersection of the measurement subframe patterns .

Embodiment 2

[0091] like Figure 4 As shown, the inter-frequency measurement configuration method in this embodiment mainly includes the following steps:

[0092] Step 401, the base station configures different inter-frequency measurement interval offsets for the user equipment at each frequency point or frequency point subset, and the measurement subframe pattern and measurement subframe cell list on each inter-frequency frequency point, and sends them to the user equipment;

[0093] Step 402, the user equipment selects different frequency points within the measurement interval period according to the received inter-frequency measurement configuration information and according to the rules agreed with the base station;

[0094] Step 403, the user equipment measures the given cell in the corresponding measurement subframe cell list according to the measurement interval starting from the measurement interval offset corresponding to the frequency point and the subframe position corresponding...

application example 1

[0097] After the base station is started, the time-domain interference coordination information of adjacent base stations is obtained through the interaction between base stations or with the core network (for adjacent cells under the same base station, the base station does not need to interact), such as ABS mode ( ABS pattern) and so on.

[0098] like Figure 5 As shown, the user equipment is currently working at frequency f3, and the base station to which the current working cell of the user equipment belongs obtains the ABS pattern of adjacent cell 1 at frequency f1 and adjacent cell 2 at frequency f2, where adjacent cell 1 has a period of 8 ms One ABS subframe, that is, 0, 8, 16, ... subframes are set as ABS, and the adjacent cell 2 has two ABS subframes with a period of 8ms, that is, 0, 1, 8, 9, 16, 17, ... subframe is set to ABS.

[0099] When a user equipment accesses a certain cell of the base station, the base station needs to configure measurement objects for the ...

Abstract

The invention discloses a different frequency measurement configuration method and a device. A base station configures different frequency measurement for user equipment according to nearly blank subframe model information of adjacent cells on each frequency point for the user equipment to perform different frequency measurement and sends different frequency measurement configuration information to the user equipment, wherein the different frequency measurement information at least comprises measurement interval deviation or a measurement subframe model; and the user equipment measures the adjacent cells on the corresponding frequency points according to the received different frequency measurement configuration information. By means of the different frequency measurement configuration method and the device, the fact that the user equipment accurately measures different frequency cells in the scene of interference coordination can be guaranteed so that the user equipment can correctly judge and switch to an appropriate different frequency cell.

Description

technical field [0001] The present invention relates to the field of communication technologies, in particular to a method and device for inter-frequency measurement configuration. Background technique [0002] In order to meet the growing demand for large bandwidth and high-speed mobile access, the Third Generation Partnership Projects (Third Generation Partnership Projects, 3GPP for short) launched the Long-Term Evolution advance (LTE-Advanced for short) standard. LTE-Advanced retains the core of LTE for the evolution of Long-Term Evolution (LTE for short), and uses a series of technologies to expand the frequency domain and air domain on this basis to improve spectrum utilization and increase system capacity. capacity etc. [0003] Generally, in order to provide wireless communication for users in a wide range, a wireless communication system needs to deploy a base station with a large coverage. Such a base station is usually called a macro base station (Macro), and a c...
