Problems solved by technology

However, since there is only one scheduling indication channel occupying the main frequency, the mobile terminal at the edge of the cell occupying the main frequency also needs to demodulate the scheduling indication information of the mobile terminal inside the cell at the same time, so that the occupation of the main frequency is very high. The mobile terminals at the edge receive a very high load of scheduling indication information

Embodiment Construction

[0028] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0029] In the technical scheme of frequency soft multiplexing in the present invention, scheduling indication channels are respectively set on the main frequency and the secondary frequency, the scheduling indication channel occupying the main frequency is used to schedule the main frequency, and the scheduling indication channel occupying the secondary frequency is used to schedule the secondary frequency . Divide the entire frequency band into two sections, one of which is used as the main frequency and the other as the sub-frequency. The primary frequency can be applied to the inner area of ​​the cell, and the secondary frequency can be applied to the boundary area of ​​the cell. In this way, the transmission power of the base station or mobile terminal on the ...

Abstract

The invention relates to a method for realizing channel in multi-carrier system. Wherein, in the region, keeping the frequency complex factor as 1; at the edge of region, using frequency group to reduce the interference between regions; setting distribution instruct channels at main and sub frequencies; the distribution instruct channel at main frequency distributes the main frequency, while the sub one distributes the sub frequency, to reduce the time domain resource, and reduce the main frequency resource for distribution instruct channel. And the mobile terminal can detect the distribution instruct channel based on itself occupied frequency, to reduce the load.

Description

technical field [0001] The invention relates to multi-carrier technology, in particular to a channel realization method in a cell of a multi-carrier system. Background technique [0002] Mobile communication technology needs to support a wide range of business types such as voice, data, audio, video, and image. In order to support multiple business types, mobile communication systems are required to support higher data rates, higher spectral efficiency, and improved quality of service (QoS , Quality of Service) guarantee mechanism, provide better mobility support and wireless network coverage, and realize the goal of providing communication services for users anytime and anywhere. At present, some mobile communications use Time Division Multiple Access (TDMA, Time Division Multiple Access) and narrowband Code Division Multiple Access (CDMA, Code Division Multipie Access) as the main access technologies, such as Global System fbr Mobile (GSM, Global System fbr Mobile Communi...
