Background technology
In order to satisfy the growing demand of user to the high-speed upward grouped data business, also in order to insert (High Speed Downlink PacketAccess with high speed downlink packet better, abbreviating as) technology matches that support to higher quality of service is provided, 3GPP inserts (High Speed Uplink Packet Access in the high speed uplink packet that Rel6 and Rel7 have introduced based on WCDMA and TD-SCDMA respectively, abbreviate HSUPA as) technology, perhaps be referred to as up enhancing (Enhanced Uplink) or strengthen dedicated channel (EnhancedDedicated Channel abbreviates E-DCH as) technology.
HSUPA has inherited technology such as mixing automatic repeat requests (Hybrid-ARQ abbreviates HARQ as) and fast dispatch from HSDPA, and increases the distinctive Enhanced Technology of ul transmissions on this basis.HSUPA has adopted the asynchronous HARQ mode of incremental redundancy (IR), merges and coding gain by obtaining to retransmit, and improves systematic function.The mode that retransmission mechanism is also the same with HSDPA have been adopted that the N channel stops and wait.
Physical layer carrying aspect, HSUPA has introduced new Physical Shared Channel, promptly strengthens uplink physical channel (E-PUCH) and carries corresponding transmission channel E-DCII.Simultaneously, in order to finish control corresponding, scheduling and feedback, HSUPA has introduced enhanced uplink random access channel (E-RUCCH), E-DCH absolute grant channel (E-DCH AbsoluteGrant Channel in physical layer, abbreviate E-AGCH as) and three physical control channels of E-DCH HARQ affirmation indicating channel (E-DCH HARQ Acknowledgement Indicator Channel abbreviates E-HICH as).
Wherein, the UE that E-RUCCH is used under the CELL_DCH state is not having to ask mandate to carry out transfer of data under the situation of resource authorization, its transmission means is the access way of preemptive type, process is identical with PRACH, and can and Packet Random Access Channel (PacketRandom Access Channel abbreviates PRACH as) share physical code channel.For the current UE that mandate is arranged, also the multiplexing Node B that passes in the MAC-e of E-PUCH PDU of schedule information that can UE is current (SI) is to reach the purpose of dispatch request.Wherein, schedule information (SI) comprises: information such as power headroom, path loss, buffer size.
The frame structure of E-AGCH as shown in Figure 1, when E-AGCH is used for Node B when UE transmits the scheduling resource authorization message, attribute field is " 00 ", keep high 2 bits in the specific information 2, all the other 3 bits are used to carry the indication of resource continuous time, can transmit following physics control information by this E-AGCH: power authorization message, time slot authorization message, code channel authorization message, interim user network identity, the number of up enhancing access channel (E-UCCH), the indication of resource continuous time, E-DCH cyclic sequence number, the indication of E-HICH channel etc.
E-HICH is used for Node B feeds back affirmation/non-affirmation (ACK/NACK) information from each transmission block to UE, in order to reduce the physical channel expense, E-HICH has adopted the mode of secondary spread spectrum, can be implemented in and carries 80 signature users on the original physical code channel at most.The user's signature sequence is related with the resource dynamic of distribution simultaneously, can satisfy the demand of supporting that the Large Volume Data user is simultaneously online.
UE is set up/distributed to when reshuffling to the E-AGCH channel by radio network controller (Radio Net Controller abbreviates RNC as) at radio bearer.E-AGCH manages in the mode of gathering and distributes, and a UE can distribute a set, and a set can comprise 1~4 E-AGCH physical channel.UE monitors all E-AGCH channels, and each Transmission Time Interval (TTI) (5ms) identifies relevant scheduling authorization information on maximum 1 the E-AGCH channel that read wherein according to UE, to carry out the E-PUCH channels transmit.
Throughput and peak rate for further raising system, 3GPP has introduced HSUPA with multicarrier, this technology can be carried out the HSUPA transmission on a plurality of carrier waves (N carrier wave) of a sub-district, the up N that can obtain of one side is doubly to the throughput of single carrier HSUPA; Also possible on the other hand N doubly improves the peak rate of single terminal.
In the multi-carrier HSUPA system, subscriber equipment can send data simultaneously on the E-PUCH of a plurality of carrier waves, each E-PUCH has its corresponding authorization channel E-AGCH, i.e. the corresponding E-PUCH resource of authorizing a carrier wave of E-AGCH, and a plurality of E-AGCH can send on a designated carrier.But, can't be informed in the pairing mandate carrier wave of each E-AGCH that sends on the designated carrier in the correlation technique terminal, thereby cause terminal to send E-PUCH can't being informed on which carrier wave after the mandate that receives E-AGCH.
