Embodiment Construction

[0105] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0106] The embodiment of the present invention is applicable to a communication system with a macro base station and a micro base station, and the system may include multiple macro base stations and multiple micro base stations, wherein each macro base station generally has the same transmit power, has the same coverage. A macro base station needs to cover an entire network by itself and provide continuous and uninterrupted services for users accessing the network....

Abstract

The invention discloses a method for starting inter-frequency measurement, user equipment and a macro base station used for implementing the method. Whether an inter-frequency measurement is performed is determined in accordance with path loss or uplink channel reception quality between the user equipment and the macro base station or a micro base station, it is ensured that the user equipment requires no additional signal or channel configuration and power consumption of the user equipment is reduced.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method for starting inter-frequency measurement, user equipment and a macro base station. Background technique [0002] The 3rd Generation Partnership Project (3GPP) plans to introduce the Heterogeneous Network (HetNet) technology in the 12th version of the Universal Mobile Telecommunications System (UMTS). HetNet is a multi-layer Wireless access network technology for networking. The traditional wireless access network is mainly a macro network layer. The macro base station in the macro network needs to cover an entire area to provide continuous and uninterrupted services for all users located in the area. On the other hand, HetNet adds one or more micro-network layers on the basis of the macro-network layer. The transmission power of the micro-base station in the micro-network is smaller than that of the macro-base station, and the coverage is much smaller tha...
