Embodiment Construction

[0031] The basic idea of ​​the present invention is to dynamically adjust the MAIO jump table of the second sub-channel user according to the user measurement report, so as to realize the interference diversity.

[0032] The implementation of the technical solution will be further described in detail below in conjunction with the accompanying drawings.

[0033] The prior art and the present invention are compared and described below, so as to better reflect the advantages of the present invention over the prior art.

[0034] As far as the existing technology is concerned, in the existing frequency hopping technology, each cell corresponds to a limited set of frequency points for frequency hopping, which is denoted as: MA={f 1 , f 2 , f 3 ,...}; each cell also corresponds to a positive integer frequency hopping sequence number (HSN), and the frequency hopping pointer sequence of frequency hopping on the MA can be obtained through the HSN, denoted as: MAI={i 1 , i 2 , i 3 ,...

Abstract

A frequency hopping method and system for supporting multi-user reusing-one-slot (MUROS) are provided. The method includes that: adjusting the skip-selection table for a mobile allocation index offset (MAIO) of a second sub-channel user dynamically based on a user measurement report to implement interference diversity. The system includes an adjusting unit, which is used to adjust the skip-selection table for the MAIO of the second sub-channel user dynamically based on the user measurement report to implement interference diversity. By using the method and system of the invention, the interference diversity function for the MUROS can be implemented, the better effect of interference diversity under the MUROS environment can be achieved and simultaneously the receiving quality of the entire signal can be improved.

Description

technical field [0001] The invention relates to a multi-user multiplexing single time slot (MUROS, M u l t i-U se rReusing-One-Slot) frequency hopping technology, in particular to a frequency hopping method and system supporting MUROS in a Global System for Mobile Communications (GSM, Global System of Mobile communications) network. Background technique [0002] In traditional networks, such as GSM networks, in order to make full use of existing frequencies and improve the utilization rate of existing frequencies, frequency hopping technology is widely used in GSM networks. The two main functions of frequency hopping are to realize frequency diversity and interference diversity. Among them, frequency diversity refers to: the ability to resist Rayleigh fading; interference diversity refers to: the ability to suppress interference signals from other co-frequency multiplexing cells. [0003] In recent years, along with the increase of people's demand for mobile voice servic...
