Method for controlling user's terminal transmitting power

Abstract

This invention discloses a method for controlling power of a UE, which pre-sets a monitor period and a RNC receives the UE communication data from the base station and determines the retransmission times of the UE data, when the period is full, the RNC gets the overrun times of the retransmission of the UE communication data in the period based on the retransmission times and the threshold value set before hand to decide the communication data volume should be received by the UE in the period to compute the target value of a new SIR to control the UE to adjust the emission power based on the target value.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to a method for controlling the transmission power of a user terminal (UE). Background technique [0002] During the communication process between the UE and the network side, the radio network controller (RNC) serving the UE controls the transmit power of the UE through the base station to which the UE accesses. For the convenience of description, the subsequent RNC serving the UE is referred to as RNC for short; the base station accessed by the subsequent UE is referred to as base station for short. The power control process is as figure 1 As shown, the specific power control process includes the following steps: [0003] Step 101: While receiving the UE communication data from the base station, the RNC also receives a data reception instruction from the base station at any time; the data reception instruction is usually included in the UE communication data sent by the base ...

Problems solved by technology

[0024] Depend on figure 1 , figure 2 It can be seen that the RNC uses the calculated new SIR target value to control the UE transmission power through the base station, but the process of calculating the new SIR target value does not involve the number of retransmissions of UE communication data, which will lead to the application of the new SIR. The UE transmit power obtained by controlling the UE transmit power with the target value is not the reasonable transmit power that should be used for UE communication, and there is even a large gap between it and the reasonable transmit power. For example, the UE transmit power obtained by controlling the UE transmit power The transmit power of the UE is too high, so that the block error rate when the base station receives the UE communication data is too small and the block error rate obviously exceeds the reasonable block error rate range required for normal communication, resulting in part of the transmit power of the UE being unnecessary Wasted; or the UE transmit power obtained by controlling the UE transmit power is too small, so that the block error rate when the base station receives UE communication data is too large and the block error rate obviously exceeds the reasonable block error rate required for normal communication rate range, causing too much UE communication data to be correctly received by the base station

[0025] Obviously, the current UE transmit power obtained by controlling the UE transmit power is not a reasonable transmit power for UE communication, and it is likely to cause unnecessary waste of part of the transmit power of the UE, resulting in increased power consumption of the UE. , The standby time is shortened, which is not conducive to the normal application of the UE; or the excessive communication data of the UE cannot be correctly received by the base station, resulting in the normal communication of the UE being affected

Also, all of the above will reduce user satisfaction
