Embodiment Construction

[0042] The inventor noticed during the invention that:

[0043] With the ever-increasing data rate and service load requirements, the traditional method of providing access with single-layer coverage of macro base stations can no longer meet the requirements. With layered coverage, some low-power base stations (Home eNodeB / Pico / Femto / Relay, home evolution base station / picocell base station / femtocell base station / relay base station) can be deployed in hot spots or indoors. to solve this problem. This low-power base station is a base station device applied in a home indoor environment, an office environment, or other hotspot small coverage environments, enabling operators to provide attractive services with higher data rates and lower costs. However, the femto base station has certain restrictions on the access of member users, and non-member users cannot access. If non-member users enter the coverage area of ​​the base station, they need to use the interference avoidance subfr...

Abstract

The invention discloses a configuration method and equipment of an almost blank subframe. The method comprises: determining the initial subframe and / or effective time of the almost blank subframe by a base station; configuring the initial subframe and / or effective time of the almost blank subframe to user equipment. The invention solves the problem that the almost blank subframe period can not correspond because a system frame number inversion time point and the start point of the almost blank subframe period can not correspondingly generate a system frame number reserve tail.

Description

technical field [0001] The invention relates to the field of wireless communication, in particular to a quasi-blank subframe ABS configuration method and equipment. Background technique [0002] For ease of expression, in this application, MUE (macro user equipment) refers to a UE (User Equipment, user equipment) that has no CSG (Closed Subscriber Group, Closed Subscriber Group) capability at all; or for a Femto (femtocell base station) For non-member UEs, the Femto's CSG ID (closed subscriber group identifier) ​​is not in the UE's CSG whitelist; [0003] Femto: a low-power home base station that only member UEs can access; [0004] Macro: macro base station; [0005] PUE: A UE that accesses pico (pico cellular base station) and works under pico. [0006] figure 1 Schematic diagram of the coverage hole for the MUE to enter the Femto, for the case of a closed mode femtocell, such as figure 1 As shown, UE1 belongs to the macro base station, and femto can only serve author...
