Problems solved by technology

[0003] In the above-mentioned MAIO hopping scheme in MUROS, since the frequency reuse relationship of MUROS users is random, a certain MUROS user will randomly perform frequency reuse with other MUROS users, which may cause serious co-channel interference and increase the corresponding The fluctuation of the communication link performance over time reduces the stability of the signaling channel and affects the call quality of MUROS users

Embodiment Construction

[0028] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0029] The behavior of multiplexing two MSs on the same time slot is called frequency reuse, which can also be called pairing. According to the convention described in the constellation diagram, the MS on the first sub-channel is called "I-channel MS". The MS on the two sub-channels is called "Q-channel MS". When more than one MS is multiplexed in MUROS on a certain time slot, it is said that the time slot is in "MUROS mode". In the exi...

Abstract

A method, device, and system for adjusting a mobile allocation index offset (MAIO) are disclosed. The method includes: obtaining standard frame selection information and a preset MAIO; selecting a standard frame according to the standard frame selection information; and setting the preset MAIO to be an MAIO of a mobile station (MS) in the standard frame. During the process of implementing the MAIO hopping solution in multi-user reusing one slot (MUROS), the MS in embodiments of the present invention selects a standard frame according to the standard frame selection information obtained from the BSS, and sets the preset MAIO obtained from the BSS to be the MAIO of the MS in the standard frame. In this way, the preset MAIO in the optimum frequency reuse relationship can be set to be the MAIO of the MS in the standard frame. Thereby, co-channel interference during the process of implementing the MAIO hopping solution in the MUROS technology is reduced, fluctuation of communication link performance with time is reduced, stability of signaling channels is improved, and therefore the call quality of the MS is guaranteed.

Description

Technical field [0001] The present invention relates to the field of communication technology, and in particular to a method, device and system for adjusting Mobile Allocation Index Offset (MAIO for short). Background technique [0002] The MAIO (MAIO Hopping) scheme is a frequency hopping scheme in Multi-User Reusing One SIot (MUROS) technology. The basic idea of ​​the scheme is to move the mobile station (Mobile Station) on the time axis. , Referred to as MS) means that the frequency reuse relationship of MUROS users is disrupted, and interference diversity between MUROS users in the cell and between MUROS users and non-MUROS users is realized. [0003] In the above implementation of MAIO hopping scheme in MUROS, since the frequency reuse relationship of MUROS users is random, a certain MUROS user will randomly reuse frequencies with other MUROS users, which may cause serious co-channel interference and increase the correspondence. The volatility of communication link performanc...
