Problems solved by technology

The disadvantage of the existing technology represented by this company's solution is that it does not fully consider the changes brought about by the introduction of new network elements in LTE (LongTerm Evolution)-R10 (version 10), and it cannot be applied to The situation after the introduction of new network elements in LTE-R10

Embodiment approach

[0152] 1. It is agreed that different layers are uploaded in the same subframe, and the synchronous subframes of different layers are distinguished by different positions in an MBSFN cycle, and the information transmitted is the subframe number and the position information of each layer;

[0153] 2. It is agreed that different layers are uploaded in the same subframe, and layer n configures MBSFN at the position of SFNmod(M*N)=n. In this case, the information to be transmitted is reduced to the subframe number, M, and the size of M can be determined according to Update cycle setting, the smaller the update cycle, the smaller M;

[0154] 3. Directly indicate subframe numbers and location information of different layers.

[0155] In specific implementation, there can be two implementation modes for step 406:

[0156] That is, after a new network element is introduced, the new network element information can be notified through the following methods:

Abstract

The invention discloses a base station internal synchronization method of a hierarchical system and a base station. The method comprises the following steps of: synchronizing the base station in a synchronous position in the configuration information of a second multicast / broadcast single frequency network subframe; submitting the configuration modification of a first multicast / broadcast single frequency network subframe to a network administer when the base station confirms that the configuration of the first multicast / broadcast single frequency network subframe is modified or submitting theconfiguration modification of the first multicast / broadcast single frequency network subframe to the network administer when the base station confirms that the configuration modification of the firstmulticast / broadcast single frequency network subframe can influence a second multicast / broadcast single frequency network subframe in the synchronous position; and synchronizing the base station in asynchronous position in the configuration information of a third multicast / broadcast single frequency network subframe, wherein the configuration information of the third multicast / broadcast single frequency network subframe is distributed by the network administer according to the configuration modification of the first multicast / broadcast single frequency network subframe. The invention provides a synchronization scheme with backward compatibility.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to a method for synchronizing in a base station of a layered system and the base station. Background technique [0002] In the mobile communication network, with the increasing requirements for data rate and coverage, the traditional method of using macro base stations to provide access can no longer meet the requirements. Cell splitting is used, and some low-power mobile phones are deployed in hot spots or indoors. The base station (Home / Pico / Femto / Relay, home base station / picocell base station / femtocell base station / relay base station) can well solve this problem. This low-power base station is a base station device applied in a home indoor environment, an office environment, or other small-coverage environments, enabling operators to provide attractive services with higher data rates and lower costs. [0003] The introduction of low-power base stations will cause interference...
