Problems solved by technology

[0011] Although the multi-carrier feature has been introduced into the HSUPA system, the single-carrier power control method is still used at present, and the single-carrier power control is not fully applicable to multi-carriers.
[0012] To sum up, for the HSUPA system at present, the multi-carrier situation is not considered when performing power control, thereby reducing the performance of power control

Embodiment Construction

[0030] In the embodiment of the present invention, the network side determines the reference expected received power of the carrier available to the terminal; the network side sends the determined reference expected received power of the available carrier to the terminal, instructing the network side to determine each authorized available carrier according to the received reference expected received power transmit power. Since power control can be performed in the case of multiple carriers, the performance of power control in a multi-carrier environment is improved.

[0031] It should be noted that the embodiment of the present invention is applicable to the HSUPA system with multi-carrier characteristics, and also applicable to the subsequent evolution system of HSUPA and other multi-carrier systems.

[0032] The embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0033] Such as figure 1 As shown, t...

Abstract

The invention relates to a wireless communication technology, in particular to a method, a system and a device for determining transmit power under a multi-carrier system. The method, the system and the device are used for power control under the situation of multi-carrier to improve power control performance. The method of the embodiment of the invention comprises the following steps that: a network side determines the reference expected receiving power of the available carriers of a terminal; and the network side transmits the reference expected receiving power of the available carriers to the terminal to instruct the terminal to determine the transmit power of each authorized available carrier according to the received reference expected receive power. By adopting the method of the embodiment of the invention, the power control can be conducted under the situation of multi-carrier and thereby the power control performance under the multi-carrier environment is improved.

Description

technical field [0001] The present invention relates to wireless communication technology, in particular to a method, system and device for determining transmission power in a multi-carrier system. Background technique [0002] HSUPA (High Speed ​​Uplink Packet Data Access) technology is an uplink enhancement scheme proposed by Release 7 of 3GPP (3rd Generation Partnership Project; third-generation mobile communication standardization organization). [0003] Among them, the channel structure of the LCR TDD HSUPA service includes two uplink channels and two downlink channels. The two uplink channels are E-RUCCH (E-DCH Random access Uplink Control Channel, E-DCH random access uplink control channel) and E-PUCH (E-DCH Physical Uplink Channel, E-DCH physical uplink channel). The two downlink channels are E-AGCH (E-DCH Absolute Grant Channel, E-DCH Absolute Grant Channel) and E-HICH (E-DCH HARQ Indicator Channel, E-DCH HARQ Indicator Channel). [0004] At present, the HSUPA sys...
