Example Embodiment

[0016] In the embodiment of the present invention, the base station uses the base station to change the downlink time slot into the uplink time slot when time synchronization is required, and receives the downlink signal of the neighboring base station through the uplink time slot; the base station performs time according to the received downlink signal Synchronization method; because the downlink time slot is changed into uplink time slot, and the downlink signal of neighboring base station is received according to the uplink time slot for time synchronization, the synchronization of different frequency bands under the condition of limited working bandwidth of micro base station is realized, saving The resource cost of the micro base station.

[0017] The embodiments of the present invention will be described in further detail below in conjunction with the accompanying drawings of the specification.

[0018] Such as figure 1 Shown is a base station synchronization method in an emb...

Abstract

The invention relates to the technical field of mobile communication, in particular to a method and a device for synchronizing base stations, and aims to solve the problems that in order to synchronize micro-base stations with adjacent base stations with different frequency bands, the operation bandwidths of the base stations are generally increased, each base station has two up links, one up link is used for monitoring signals of the adjacent base stations, the other up link is used for processing business data, and resource costs of the micro-base stations are increased in the prior art. When the base stations need time synchronization, a downlink time slot is changed into an uplink time slot, downlink signals of the adjacent base stations are received by the uplink time slot, and a time synchronization method is implemented for the base stations according to the received downlink signals. As the downlink time slot is changed into the uplink time slot and the time synchronization method is implemented according to the downlink signals received by the uplink time slot from the adjacent base stations, the operation bandwidths of the micro-base stations are not increased under the condition of limited existing operation bandwidths of the micro-base stations, the micro-base stations and the adjacent base stations with the different frequency bands are synchronized, and the resource costs of the micro-base stations are saved.

Description

technical field [0001] The present invention relates to the technical field of mobile communication, in particular to a synchronization method and device for a base station. Background technique [0002] The micro base station is a mobile communication system that uses cellular communication technology to achieve micro cell coverage. Cellular base stations include TDD base stations and FDD base stations. The TDD base stations work based on time division and have higher requirements for timing synchronization. [0003] At present, TDD base stations mainly obtain synchronization through GPS, Beidou, 1588, and air interface synchronization. For the micro base station system, due to the constraints of indoor application occasions, volume and cost and other factors, 1588 and air interface synchronization are usually used for synchronization. However, since the network application of the 1588 protocol is not very wide, most micro base stations use air interface synchronization. ...
