Technical field
The present invention relates to the electronic communication field, relate in particular to a kind of method, Apparatus and system of transmitting control information of enhanced uplink dedicated channel.
Background technology
Along with developing rapidly of the third generation communication technology, many new technology have appearred.Wherein, HSDPA (high speed downlink packet access) technology is a kind of descending wireless enhanced technology that 3GPP (third generation collaborative project) introduces in Release (version) 5.The HSDPA technology is owing to having adopted key technologies such as the link adaptation techniques based on Adaptive Modulation and Coding, the HARQ (mixing automatic repeat requests) based on physical layer retransmission and soft merging, quick multi-user's packet scheduling, the short frame of 2ms, thereby have advantages such as spectrum efficiency height, downlink transfer speed is big, propagation delay time is little, thereby can provide effective twelve Earthly Branches to hold to Packet data service.
HSUPA (high speed uplink packet access) technology, promptly E-DCH (enhancing special uplink channel) technology is that 3GPP introduces in Release 5 after the HSDPA, a kind of wireless enhanced technology of introducing in Release 6.Two kinds of patterns of E-DCH technical support 10ms TTI (Transmission Time Interval) and 2ms TTI.Because the E-DCH technology has adopted based on the up fast packet scheduling of Node B (Node B) and quick HARQ key technologies such as (mixing automatic repeat requests), thereby have advantages such as spectrum efficiency height, uplink speed is fast, propagation delay time is little, thereby can more effectively support grouping data services such as real-time game business, file are uploaded, broadband multimedia services to use.
The relevant uplink physical channel of E-DCH technology comprises: E-DPDCH (the E-DCH Dedicated Physical Data Channel that is used for carrying user data, the E-DCH Dedicated Physical Data Channel) and be used to carry the E-DPCCH (E-DCH DedicatedPhysical Control Channel, E-DCH Dedicated Physical Control Channel) of the required control information of demodulate reception E-DPDCH.
Fig. 1 is the frame assumption diagram of existing E-DPCCH.As shown in Figure 1, each radio frames is divided into 5 subframes, and each subframe is 2ms, and each subframe takies 3 time slots, 2560 chips of each time slot.Table 1 is the time slot format table of E-DPCCH, and wherein, spreading factor is 256,10 bits of each time slot carrying, and each subframe is carried 30 bits like this, 150 bits of every frame carrying.

E-TFCI, 7 bits can be indicated 128 kinds of transmission block sizes altogether altogether.
" Happy " (satisfaction) bit has only 1 bit, is used to refer to UE (subscriber equipment) whether present service authorization parameter is satisfied with, and promptly whether the resource that Node B is distributed to oneself is satisfied with.
The technical scheme of existing transmission E-DCH control information is not transmitted modulation system information, because in the technical scheme of existing transmission E-DCH control information, the acquiescence modulation system is BPSK (BinaryPhase shift Keying, binary phase shift keying) modulation.
According to RSN, code rate, and TTIN (number of TTI), E-DCH RVIndex (strengthening special uplink channel redundancy versions index) value can be set.As shown in table 2, table 2 is RSN, code rate, and the relation table of TTIN and E-DCH RV (strengthening the special uplink channel redundancy versions) index.
