Embodiment Construction

[0060] In the power control method of the present invention, the dedicated channel in the physical channel is set as the reference channel; the power control is performed on the reference channel to obtain the power value of the reference channel after power control; then according to the power value of the reference channel obtained, adjust The power of other channels in the physical channel.

[0061] In the present invention, the set reference channel can be a dedicated channel in the downlink physical channel, called the downlink reference channel, and use the power value after the power control of the downlink reference channel to adjust other channels in the downlink physical channel; in addition, A dedicated channel in the uplink physical channel can be set as a reference channel, called an uplink reference channel, and the power value of the uplink reference channel after power control is used to adjust other channels in the uplink physical channel.

[0062] Preferably,...

Abstract

The present invention discloses a power control method comprising that: A. a special channel is arranged in the physical channel as the basic channel; B. the power of the basic channel is controlled and then the power value is obtained; C. based on the power value obtained in the step B, the powers of other channels in the physical channel are regulated. The method provided by the present invention realizes a complete power control plan in physical channel of HSUPA. In addition, the present invention also provides a power control device. With the method and the device provided by the present invention for power control, the special channel which has a large data flow is taken as the basic channel and the feedback efficiency of power control is promoted, the power control function is ensure; moreover, the use of HSUPA technology is guaranteed.

Description

technical field [0001] The invention relates to mobile communication technology, in particular to a power control method and a power control device. Background technique [0002] High Speed ​​Packet Uplink Data Access (HSUPA) technology, as a sister technology of High Speed ​​Packet Downlink Access (HSDPA), makes the Universal Mobile Telecommunications System (UMTS) more powerful and perfect in terms of data transmission. HSUPA can carry applications such as DVD-quality video streams, conference calls, real-time games, music, email, and MMS. Compared with dedicated channels (DCH, Dedicated Channel), HSUPA can obtain higher user throughput. At the same time, HSUPA can also provide differentiated services more conveniently. Users with different priorities can get different service qualities. Higher priority users can be allocated higher bandwidth and more resources to enjoy better services. [0003] In UMTS, power control plays a very important role in power consumption, syst...
