Abstract
This invention discloses a method for getting quality of up channels at the network of a high speed packet access system including: node B carries information of channel quality on FP frame of channel E-DCH and reports it to a radio network controller, which can get quality of up channels timely and takes it as the base of out-circle power control so as to increase communication quality of users.
Description
Technical field
The frequency resource that the present invention relates to a kind of radio honeycomb communication system is shared method, and the network side that relates in particular to the high speed up packet access system of Wideband Code Division Multiple Access (WCDMA) (WCDMA) mobile communication system obtains the enhanced uplink channel method for quality.
Background technology
The up flank speed that the R99 standard agreement of WCDMA mobile communication system offers the user is generally 384kbps, and hot zones can provide the speed of 2Mbps.From the supported performance that is used for the dedicated channel (dedicatedchannel:DCH) of transmitting grouped data of R99, for the user in general area, the function of the transmission Packet Service that the R99 standard agreement provides can satisfy user's demand, but along with Packet Service user's increase and to the demand of high speed packet service, the rate bandwidth that R99 provides can not satisfy hot zones user's demand; Therefore the R5 standard agreement has been introduced a kind of enhanced uplink dedicated transmission channel (Enhanced UL DCH:E-DCH), and this channel has adopted and mixed (HARQ) and Adaptive Modulation and Coding (AMC) technology of retransmitting automatically, makes peak rate can reach 5.76Mbps.Its final purpose is by providing high speed packet service to be inserted the capacity that increases system and reduces transmission delay to improve the requirement of user to service quality (Quality of Service:Qos).
E-DCH can exist simultaneously with DCH, also can use separately, though the characteristics of E-DCH channel and the characteristics of DCH have very big difference, special-purpose control physical channel (Dedicated Physical Control Channel:DPCCH) all exists, and there is closed-loop power control in DPCCH.The purpose of closed-loop power control is in order to adjust the transmitting power of each travelling carriage, reduce the influence of this near-far interference, guarantee that as far as possible the power that the base station receives all travelling carriages all equates, thereby make each user can both satisfy the service quality (Quality of Service:Qos) of transport service.Closed power control comprises inner loop power control and exterior ring power control, inner loop power control 3GPP agreement has been reserved rule, but the standard of inner loop power control institute foundation: and target signal interference ratio (Signal to Interference Ratio target:SIRtarget) need dynamically be adjusted according to user's Qos demand and current channel quality by service wireless network controller (Serving Radio Network Controller:SRNC).SRNC can have the quality of propagation channel quality, physical channel according to the foundation of channel quality, because being the Block Error Rate that guarantees the user, the final purpose of closed-loop power control reaches certain requirement, therefore when transmission channel has more data to send, then adopt transmission channel quality as the judgement foundation, when transmission channel has less data or free of data to send, then can adopt the physical channel quality as the judgement foundation.
Present 3GPP protocol specification, at dedicated transmission channel (DCH), carried channel quality information (QE) on its FP frame, and radio network controller can be by the NBAP signaling to Node B, the report manner that reports mode and channel quality of FP frame, according to the channel quality (transmission channel quality or physical channel quality) that Node B is reported, SRNC can be used as the basis for estimation of external circule power control.But introduce E-DCH (enhanced uplink dedicated transmission channel) afterwards at the R6 version, the information of not carrying channel quality on the FP frame of E-DCH, if therefore working as user uplink does not exist under exclusive data physical channel (the DedicatedPhysical Data Channel:DPDCH) situation, when having data to send on E-DCH, the user (, is about to seldom have data to send on then such as downloading service; Perhaps when Node B sends data owing to the load reason has limited user uplink), then radio network controller can be inferred current channel quality according to the entrained number of retransmissions of E-DCH FP frame; If but on the E-DCH when not having data to send to radio network controller, then radio network controller can't obtain any channel quality information from E-DCH FP frame.Therefore radio network controller can't be adjusted the signal interference ratio desired value of up Dedicated Control Channel (DPCCH) this moment, so when the quality of wireless channel variation, because adjustment signal interference ratio desired value that can not be real-time then can cause radio link failure, final call drop.
Summary of the invention
