Problems solved by technology

[0010] (2) Power increase limit Power_Raise_Limit, within each adjustment window length DL_Power_Averaging_Window_Size (represents how many adjustment cycles), the power increase cannot exceed the magnitude corresponding to Power_Raise_Limit (represents the adjusted db number)
[0013] Therefore, in some cases, the power control method of the current protocol has a too long delay, and the transmission quality of the air interface information is not guaranteed during this period. At least, it will cause retransmission at the upper layer of the service, which will affect the service delay performance. In severe cases, the connection between the terminal and the base station will be interrupted, resulting in service drop

Embodiment Construction

[0026] In Embodiment 1 of the present invention, a power control method such as figure 1 shown, including the following steps:

[0027] Step s101 , the NodeB receives the reconfiguration signaling, and judges that the currently used inner loop transmit power needs to be changed.

[0028] Specifically, when the NodeB receives the reconfiguration signaling from the RNC, if the reconfiguration signaling requires reconfiguration from a service with a large SF to a service with a small SF, it determines that the currently used inner loop transmit power needs to be increased. When the SF is reduced from a large value to a small value, the power range that needs to be increased is relatively large, so it is necessary to increase the power range to the required value as soon as possible; similarly, if the reconfiguration signaling requires a small SF When the service is reconfigured to a service with a large SF, it is determined that the currently used inner-ring transmit power needs...

Abstract

The embodiment of the invention discloses a method for controlling power, comprising the following steps: the requirement of change of currently used launching power is determined and new launching power is acquired; the currently used launching power is directly adjusted to the new acquired launching power to launch. The embodiment of the invention discloses a base station used for power control. By the method and the equipment provided by the embodiment of the invention, the base station controls whether the power needs adjusting, and acquires the adjusted launching power, and the process does not require participation of a wireless network controller, thereby reducing time-delay of power adjustment, and achieving the aim of controlling the power smoothly, quickly and accurately.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a power control method and equipment. Background technique [0002] "Near and far effect" is an important factor affecting the performance of the communication system. If the mobile phones in the cell all transmit at the same power, the signal from the mobile phone near the base station will be stronger, and the transmission power of the mobile phone farther from the base station will be attenuated. Seriously, sometimes the mobile phone close to the base station will even block the communication of the entire cell; similarly, if the base station transmits to each mobile phone with the same power, the mobile phone far away from the base station will also affect the reception quality due to power attenuation, and the same far away from the base station Mobile phones will also receive interference from base stations in neighboring cells, resulting in "edge effects". ...
