Detailed description of the invention
Technical scheme is further illustrated below in conjunction with Figure of description and specific embodiment.Should be appreciated that specific embodiment described herein is only in order to explain the present invention, is not intended to limit the present invention.
Fig. 1 is the present invention mobile the Poewr control method first embodiment schematic flow sheet based on VAMOS pairing user；The present invention includes step based on mobile the Poewr control method of VAMOS pairing user:
Step S01, VAMOS pairing user each carries out uplink power control judgement, it is determined that ascending power adjusts step-length, it is thus achieved that ascending power grade；
After a time slot is re-used, two users each carry out uplink power control judgement, calculate power adjustment step size, it is thus achieved that power grade；Adjust step-length to arrange according to concrete condition, in embodiments of the present invention, it is preferred to 2dB.The ascending power court verdict of each user can have state three kinds different: power remains unchanged, power increases and power subtracts.
Step S02, judge two pairing users ascending power grades whether meet SCPIR restriction；
According to the ascending power grade obtained, it is judged that whether uplink receiving level MS1level and the MS2level of two pairing users meets SCPIR restriction:
| MS1level (dB)-MS2level (dB) | <=| SCPIR (dB) |；
Wherein, uplink receiving level MS1level, according to ascending power grade MS1, carries out estimating and obtaining；Uplink receiving level MS2level, according to ascending power grade MS2, carries out estimating and obtaining.
If so, step S03 is then performed；
If it is not, then perform step S04；
Step S03, by two match users ascending power grade be issued to mobile platform；
Step S04, according to obtain ascending power grade, carry out corresponding VAMOS power control.
Owing to the ascending power court verdict of each user can have state three kinds different: power remains unchanged, power increases and power subtracts；Owing to there is SCPIR constraint between two pairing user uplink power grades, except the combinations of states that two pairing user uplink power all remain unchanged, other power ratings combination of two pairing users all would be likely to occur the problem that power difference is excessive；For the situation that the power difference of two pairing other power ratings of user combination existence is excessive, correspondingly four kinds of various combination modes of four kinds of modes difference correspondence two pairing user power states that VAMOS power controls:
Mode one: wherein a user uplink power increases or subtracts, and another user uplink power remains unchanged；
Mode two: two users are ascending power and increase；
Mode three: two users are ascending power and subtract；
Mode four: wherein a user uplink power increases, and another user uplink power subtracts.
The present invention is by judging whether the ascending power grades of two pairing users meet SCPIR and limit and carry out corresponding VAMOS power according to different situations and control this technical scheme, solve the problem that two pairing user power have big difference, reach the beneficial effect of the ascending power grade finding out applicable two pairing user's pairings.

Being the present invention mobile the output control device first embodiment structural representation based on VAMOS pairing user with reference to Fig. 8, Fig. 8, the present invention includes based on mobile the output control device of VAMOS pairing user:
Power judging module 01, each carries out uplink power control judgement for VAMOS pairing user, it is determined that ascending power adjusts step-length, it is thus achieved that ascending power grade；
Power control module 02, for according to the ascending power grade obtained, it is judged that whether the ascending power grade of two pairing users meets SCPIR restriction；If so, then the ascending power grade that two match user is issued to mobile platform；If it is not, then according to the ascending power grade obtained, carry out corresponding VAMOS power and control.
When there is VAMOS user and matching, in power judging module 01, VAMOS pairing user each carries out uplink power control judgement, it is determined that ascending power adjusts step-length, it is thus achieved that ascending power grade；According to power control court verdict, power control module 02 judges whether the ascending power grade of the two user meets SCPIR restriction.If meeting SCPIR restriction, then directly it is handed down to mobile platform；If being unsatisfactory for SCPIR restriction, the power control module 02 different conditions according to the concrete up power grade of two users, different control models is adopted to find the power adjustment direction meeting each user and be suitable for the ascending power grade of two pairing user's pairings.
Owing to the ascending power court verdict of each user can have state three kinds different: power remains unchanged, power increases and power subtracts；Owing to there is SCPIR constraint between two pairing user uplink power grades, except the combinations of states that two pairing user uplink power all remain unchanged, other power ratings combination of two pairing users all would be likely to occur the problem that power difference is excessive；For the situation that the power difference of two pairing other power ratings of user combination existence is excessive, correspondingly four kinds of various combination modes of four kinds of modes difference correspondence two pairing user power states that VAMOS power controls:
Mode one: wherein a user uplink power increases or subtracts, and another user uplink power remains unchanged；
Mode two: two users are ascending power and increase；
Mode three: two users are ascending power and subtract；
Mode four: wherein a user uplink power increases, and another user uplink power subtracts.
For four kinds of various combination modes of two pairing user power states, power control module 02 is to there being VAMOS power control mode four kinds different；Four kinds of different modes that VAMOS power controls have described its concrete enforcement step in embodiment above, do not repeat them here.
The present invention can select different power control modes according to the different capacity state of pairing user based on mobile the output control device of VAMOS pairing user, has reached to find out the beneficial effect of the ascending power grade being suitable for pairing user's pairing.
Being the present invention mobile output control device the second example structure schematic diagram based on VAMOS pairing user with reference to Fig. 9, Fig. 9, the present invention also includes based on mobile the output control device of VAMOS pairing user:
Initial synchronization module 03, controls initial synchronisation for VAMOS pairing user power；
The initial module 03 that controls is when base station receives measurement report or after the channel of base station is activated, it is judged that whether current time slots exists VAMOS user's pairing；If time slot exists users multiplexing, and is initial pairing, then remove the related data for uplink power control that the two user preserves, keep power control synchronization, put flag bit simultaneously；If current time slots is absent from users multiplexing, then carry out common power control.
Initially control module 03 by VAMOS pairing user power is controlled initial synchronisation, reached minimizing pairing user power and adjusted the beneficial effect of error probability, maintenance pairing user power control synchronicity.
The foregoing is only the preferred embodiments of the present invention; not thereby its scope of the claims is limited; every equivalent structure utilizing description of the present invention and accompanying drawing content to make or equivalence flow process conversion; directly or indirectly it is used in other relevant technical fields, all in like manner includes in the scope of patent protection of the present invention.
