Embodiment Construction

[0021] In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, the following will describe in detail with reference to the drawings and specific embodiments.

[0022] In the LTE system, the frequency (F1) where the UE is located is the frequency where the serving cell is located. Taking the frequency of the UE as the standard, the measurement can be divided into intra-frequency measurement, inter-frequency measurement and inter-system measurement.

[0023] The serving cell refers to the cell where the UE is currently located.

[0024] Many micro cells (Pico Cells) and small cells (Small Cells) are introduced into the LTE system to improve the throughput and expand the coverage of the communication system.

[0025] For the convenience of description, in the following embodiments, micro cells and small cells are collectively referred to as neighboring cells. The measurement period in the prior art is collectivel...

Abstract

The embodiment of the invention provides a method for measuring a reference signal between UE (user equipment) and a base station and the base station. The method is applied to the base station and comprises the following steps: receiving a first measurement report reported by a first measurement configuration issued by the UE on the basis of the base station; when a distance between the position of the UE and an adjacent cell is determined to be smaller than a first distance threshold value according to the first measurement report, sending a second measurement configuration to the UE to indicate the UE to measure a reference signal of the adjacent cell according to an appointed second measurement period in the second measurement configuration, wherein the second measurement period is shorter than a corresponding first measurement period in the first measurement configuration; and receiving a measurement result which is acquired and encapsulated in a second measurement report by the UE after the adjacent cell is measured according to the second measurement period. In a moving process of the UE, after the second measurement configuration from the base station is received, the adjacent cell is measured in the second measurement period, and a more precise result is reported to the base station, so that the base station can be used for carrying out accurate switching between cells for the UE.

Description

technical field [0001] The present invention relates to a mobile network measurement technology, in particular to a method for measuring a reference signal between a UE and a base station and a base station. Background technique [0002] In the Long-Term Evolution (LTE, Long-Term Evolution) system, UE (User Equipment, user equipment) performs measurement according to the measurement configuration information set by the base station. The types of measurement include: same-frequency measurement, different-frequency measurement and different-system measurement. Types of measurements correspond to different measurement requirements. According to the existing protocol, the measurement period MP1 (Measurement Period) of the same frequency measurement is 200 milliseconds. If the UE is not configured with measurement gap (Measurement, GAP) and discontinuous reception (Discontinuous Reception, DRX), the UE needs to measure within the measurement period. For the reference signal rece...
