Description

A kind of mthods, systems and devices of definite transmitting power

Technical field

The present invention relates to wireless communication technology, particularly a kind of mthods, systems and devices of definite transmitting power.

Background technology

At HSUPA (High Speed Uplink Packet Access, the access of high speed uplink bag) in the system, NodeB (evolution base station) is when scheduling UE (subscriber equipment), adopt and send the transmitting power that PRRI (Power ResourceRelated Information, power resource relevant information) controls UE.

At present, the method for the transmitting power of control UE comprises the following steps:

Step 1, RNC (Radio Network Controller, radio network controller) send to UE by measuring control messages with UE place adjacent cells of cells sign.

Step 2, UE determine the path loss of corresponding district according to adjacent cell ID, and go out SNPL (Serving and Neighbour Cell Pathloss, service and neighbor cell path loss) according to the path loss calculation that obtains.

When step 3, UE send data at needs, UPH (UE Power headroom, the terminal power rising space) and SNPL are sent to NodeB.

Step 4, NodeB are provided with PRRI according to the UPH and the SNPL that receive, and the PRRI after will being provided with sends to UE.

Step 5, UE adjust the transmitting power of self according to the PRRI that receives.

Aforesaid way also will consider the path loss of all adjacent sub-districts of sub-district, UE place when considering UPH.

For FDD (Frequency division duplex, Frequency Division Duplexing (FDD)) system, each sub-district has only a frequency, adopt identical networking, UE in the sub-district to transmit to the UE in the adjacent sub-district be influential, so UE reports SNPL, need comprise information of adjacent cells.

For TDD (Time division duplex, time division duplex) system, there is multifrequency point in each sub-district, adopt identical networking, UE is distributed on a plurality of frequencies, if the UE in the same adjacent sub-district of the UE of this sub-district not at a frequency, then the UE in the sub-district to transmit to the UE in the adjacent sub-district be not influence, UE reports SNPL, does not then need to comprise information of adjacent cells.

TDD has adopted the method for FDD at present, when UE is carried out SNPL measurement control, around inciting somebody to action, exists the adjacent sub-district of UE place frequency all to be notified to UE, carries out the measurement of SNPL.NodeB because consider SNPL, therefore can make definite PRRI on the low side, thereby reduce the transmitting power of UE and the uplink service speed of UE in scheduling UE like this.

In sum, when determining the transmitting power of UE, the subdistrict frequency point according to the UE place does not take the transmitting power that situation is determined UE, thereby might reduce the transmitting power of UE and the uplink service speed of UE at present.
