Problems solved by technology
[0004] Due to the SCPIR (SubChannelsPowerImbalanceRatio, subchannel power ratio) constraint between the power levels of the two paired users, there will be a problem of excessive power difference between the two paired users of VAMOS, which is not conducive to the same-slot pairing

Embodiment Construction
[0069] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0070] figure 1 It is a schematic flow chart of the first embodiment of the mobile station power control method based on VAMOS paired users in the present invention; the mobile station power control method based on VAMOS paired users in the present invention includes steps:
[0071] Step S01, VAMOS paired users make their own uplink power control decisions, determine the uplink power adjustment step size, and obtain the uplink power level;
[0072] When a time slot is multiplexed, the two users make uplink power control decisions respectively, calculate the power adjustment step size, and obtain the power level; the adjustment step size can be set according to specif...

The invention discloses a mobile station power control method and a device based on voice services over adaptive multi-user channels on one slot (VAMOS) pairing users. The method comprises a first step of carrying out uplink power control judgments on the VAMOS pairing users respectively to ensure a VAMOS power adjustment method so as to obtain uplink power grades, a second step of judging whether the uplink power grades of two pairing users meet component channel power ratio SCPIR limitations or not, wherein if the uplink power grades of the two pairing users meet the component channel power ratio SCPIR limitations, the uplink power grades of the two pairing users are sent to a mobile station, and if the uplink power grades of the two pairing users do not meet the component channel power ratio SCPIR limitations, corresponding VAMOS power adjustment is carried out according to the obtained uplink power grades. According to the mobile station power control method and the device based on the VAMOS pairing users, the purpose of how to find the uplink power grades suitable for the VAMOS pairing users with large power differences is achieved. Under the condition of not adding frequency resources, the pairing users are successfully reused on the same slot time of the same frequency point so as to improve voice capacities of each mobile transceiver station and a whole system and improve the utilization rate of spectrum resources.
Description
technical field [0001] The present invention relates to the field of mobile station power control, in particular to a mobile station power control method and device based on VAMOS (VoiceServicesOverAdaptiveMulti-userChannelsOnOneSlot, a voice service carrying adaptive multiple user channels on one time slot) paired users. Background technique [0002] With the continuous increase of the number of wireless communication system users, the voice service also increases, which brings enormous pressure to the existing network. The increasing GSM (Global System For Mobile Communications, Global System for Mobile Communications) users require the existing network capacity And the contradiction between the limited frequency utilization resources is becoming more and more prominent. [0003] In order to alleviate the spectrum pressure of GSM and improve the utilization rate of spectrum resources, VAMOS technology is proposed. VAMOS technology is to multiplex two users to the same tim...
