Abstract

The invention discloses a method and a device for controlling the transmission power of mobile stations, belonging to the communication technology field. The method for controlling the transmission power of mobile stations comprises the following steps: acquiring signals of two mobile stations, and adjusting the transmission power of the two mobile stations so that the difference of the intensityof the signals of the two mobile stations meets the first preset requirement or the ratio of the intensity of the signals of the two mobile stations meets the second preset requirement. The device forcontrolling the transmission power of mobile stations comprises an acquiring module and a cooperatively controlling module. In the invention, the power of the two mobile stations is cooperatively controlled, thus the overlarge signal interference is effectively inhibited, the demodulation performance and the multiplex effect of the multiplex mobile station are improved, and the business quality is guaranteed when the MUROS technology is used for improving the phonetic capacity.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method and device for controlling transmission power of a mobile station. Background technique [0002] Traditional voice uses the allocation method of one time slot for one user. As the number of users continues to increase, more voice channels need to be carried on the same resource. Therefore, a time slot and ARFCN (Absolute Radio Frequency Channel Number, The technology of multiplexing multiple users on Absolute Frequency Point Number), such as MUROS (Multi-User ReuseOne Slot, multiple users reuse the same time slot) technology, can obtain a significant increase in capacity on a fixed carrier frequency and spectrum. [0003] see figure 1 , MUROS multiplexes two users MS (Mobile Station, mobile station) 1 and MS2 on one time slot, and MUROS provides two sub-channels, each MS occupies a sub-channel, and the sub-channels are trained through orthogonal or nearly orthogo...
