Embodiment Construction

[0051] As mentioned in the background art, it is difficult to know whether adjacent cells on a certain frequency are synchronized, and if maintenance is only performed by the operator, the workload of the operator will be increased.

[0052] In the prior art, the base station may configure the UE to measure the radio frame deviation value between the primary cell and the primary secondary cell. However, the UE generally does not support the measurement of the synchronization relationship between non-serving cells, nor does it support the measurement of subframe information of inter-frequency neighboring cells.

[0053] In order to make the above objects, features and advantages of the present invention more comprehensible, specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0054] figure 1 It is a flow chart of a method for synchronously measuring adjacent cells according to an embodiment of the pres...

Abstract

The invention discloses an adjacent cell synchronization measurement method and device. The adjacent cell synchronization measurement method comprises the steps of sending a synchronization measurement configuration information to user equipment when it is known that the user equipment has the capability of measuring synchronization, thereby instructing the user equipment to measure a synchronization relationship of adjacent cells; and receiving a synchronization measurement report from the user equipment, wherein the synchronization measurement report comprises the synchronization relationship of adjacent cells. According to the technical scheme provided by the invention, the efficiency of measuring the synchronization relationship of the adjacent cells is improved.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a method and device for synchronously measuring adjacent cells. Background technique [0002] In the Long Term Evolution (LTE) system, the user equipment (User Equipment, UE, or user terminal) in the connected state needs to measure the serving cell and its neighboring cells in order to evaluate the serving cell and its neighboring cells that meet the reporting conditions. In a neighboring cell, the base station makes a decision on whether to handover according to the measurement report of the UE. The adjacent cell may be a same-frequency cell or a different-frequency cell, where the same-frequency refers to the same frequency as the serving cell of the UE, and the different-frequency refers to a different frequency from the serving cell of the UE. [0003] In the prior art, there is usually only one serving cell for the UE, and the UE receives system mess...
