When existing VAMOS user to match, in power judging module 01, VAMOS pairing user carries out the uplink power control judgement separately, determines ascending power adjustment step-length, obtains the ascending power grade; According to the power control court verdict, power control module 02 judges whether these two users' ascending power grade satisfies the SCPIR restriction.If satisfy the SCPIR restriction, directly be handed down to travelling carriage; If do not satisfy SCPIR restriction, power control module 02 is according to the different conditions of two users' concrete ascending power grade, and the power that adopts different control models to find to satisfy each user is adjusted direction and is fit to the ascending power grade that two pairing users match.
Because each user's ascending power court verdict can have three kinds of different states: power remains unchanged, power increases subtracts with power; Owing to having the SCPIR constraint between two pairing user uplink power grades, except the combinations of states that two pairing user uplink power all remain unchanged, all may there be the excessive problem of power difference in other power rating combinations of two pairing users; Make up for two other power ratings of pairing users the excessive situation of power difference that exists, correspondingly four kinds of four kinds of various combination modes that modes difference corresponding two is matched the user power states of VAMOS power control:
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, 02 pair of power control module should have four kinds of different VAMOS power control modes; Explained its concrete implementation step in four kinds of different modes execution mode in front that VAMOS power is controlled, do not repeated them here.
The travelling carriage output control device that the present invention is based on VAMOS pairing user can be selected different power control modes according to pairing user's different capacity state, has reached the beneficial effect of finding out the ascending power grade that is fit to pairing user pairing.
With reference to Fig. 9, Fig. 9 is travelling carriage output control device the second example structure schematic diagram that the present invention is based on VAMOS pairing user, and the travelling carriage output control device that the present invention is based on VAMOS pairing user also comprises:
When initial control module 03 is received measurement report in the base station or after the channel of base station is activated, judge whether current time slots exists VAMOS user to match; If there is users multiplexing in time slot, and be initial pairing, remove the related data that is used for uplink power control that these two users preserve, keep power to control synchronous, be set up simultaneously flag bit; If there is not users multiplexing in current time slots, carries out common power and control.
The above is only the preferred embodiments of the present invention; not thereby limit its scope of the claims; every equivalent structure or equivalent flow process conversion that utilizes specification of the present invention and accompanying drawing content to do; directly or indirectly be used in other relevant technical fields, all in like manner be included in scope of patent protection of the present invention.
