Description

[0001] METHOD AND APPARATUS FOR SUPPORTING OF MULTIPLE REPEATER MODE [0002]

The present invention relates to a mobile communication field, and more particularly, to a repeater mode in which an extended cell, which is an area covered by a repeater, is operated on the same condition as a basic cell, or a multiple repeater capable of selectively supporting a sector mode operating in a different condition from a basic cell Mode support method and apparatus.

Recently, due to the rapid development of communication, computer network and semiconductor technology, not only various services using wireless communication networks have been provided, but the demand of users has been increasing day by day, and the global wireless Internet service market has been exploding Trend. Accordingly, a service provided by a mobile communication system using a wireless communication network is being developed not only as a voice service, but also as a multimedia communication service for transmitting various data. Recently, with the increase of smart phones and the demand for data traffic, mobile operators are investing in equipment and technology considering system load or impact to accommodate increased data traffic in various ways.

The function of extending the service area in the wireless communication service is a main function required by the base station. In order to expand the service area in various terrains, base station manufacturers provide various types of base station products to telecommunication service companies. Various types of base stations include a large base station, a medium base station, a small base station, and a small base station. When a user equipment (UE) moves from one base station to another, a handover (H / O) is triggered. In order to reduce the handover, a repeater is used that enlarges the service area within the same cell.

Most repeaters are connected to the output terminal of the base station and use RF (Radio Frequency) signals of the base station. The base station output is coupled to the antenna to provide communication services for the base cell. The RF signal of the base station is connected to the repeater system through the D / C (Directional Coupler) at the output terminal of the base station. A donor and a relay RU (Radio Unit) constituting a repeater system typically perform a signal processing process for each RAT (Radio Access Technology) signal and FA (Frequency Assignment) Service. The signal processing includes analog signal processing and optical transmission signal processing.

In the case of a single RAT, the repeater can receive the RF signal at the output terminal of the base station and provide a communication service to the extended cell. In the case of multiple RATs, the base station may provide services such as LTE (Long Term Evolution) and WCDMA (Wideband Code Division Multiple Access), and the base station may output a plurality of signals adjacent in frequency. If the repeater uses the output signal of the base station having the adjacent frequency, many problems may occur.

1 is an exemplary diagram illustrating a cell service radius in a multiple RAT environment.

FIG. 1 shows cell radiuses for a basic cell and an extended cell in a multiple RAT environment providing LTE (omni alpha), WCDMA (omni alpha, F1, F2) services. The WCDMA service cell radius R_Wm or the LTE service cell radius R_Lm may be adjusted in the basic cell by adjusting setting parameters of a DU (Digital Unit) (not shown) and a RU (Radio Unit) . If the LTE service cell radius R_Lm in the base cell is set to be smaller than the WCDMA service cell radius R_Wm, the service cell radius of the extended cell served through the repeater is set to be similar to that of the basic cell. That is, in the extended cell, the LTE service cell radius R_Le is set to be smaller than the WCDMA service cell radius R_We.

However, since the repeater system does not perform signal processing on each RAT signal, there is no variable that can control the signal characteristics of each RAT signal. There is no way to increase only the LTE service cell radius in the extended cell because the service cell radius of the basic cell is changed.

Even if the user wants to increase the capacity of the user in the extended cell due to other requirements, current repeater system and base station type can not satisfy various cell radius and user capacity adjustment requirements.
