Embodiment
For making object, technical scheme and the advantage of the embodiment of the present invention clearer, below in conjunction with the accompanying drawing in the embodiment of the present invention, technical scheme in the embodiment of the present invention is clearly and completely described, obviously, described embodiment is the present invention's part embodiment, rather than whole embodiment.Based on the embodiment in the present invention, those of ordinary skills, not making the every other embodiment obtaining under creative work prerequisite, belong to the scope of protection of the invention.
Fig. 1 is the flow chart of control method for uplink information channel embodiment mono-of the present invention, and as shown in the figure, the method comprises the steps:
For example, in the time that this upward signal can be independent intermediate code sequence, can determine power control strategy according to the signal quality of the independent intermediate code sequence receiving, the transmitting power of the up channel of for example rising or reduction subscriber equipment etc.When this upward signal, in order to strengthen uplink physical channel, (Enhanced-PhysicalUplink Channel is called for short: when upward signal E-PUCH), can determine power control strategy according to the signal quality of this upward signal receiving similarly
Wherein, described transmitting power control (Transmit Power Control, be called for short: TPC) command word (commands) has comprised equipment for indicating user and how to adjust the order of uplink channel transmission power, as " raising (UP) " or " reducing (DOWN) " etc.
Wherein, strengthen dedicated channel (Enhanced Dedicated Channel, be called for short: E-DCH) mixed automatic retransfer request (Hybrid Automatic Repeat reQuest, be called for short: HARQ) confirm indicating channel (Acknowledgement Indicator Channel, be called for short: E-HICH) be kind of a spreading factor (Spreading Factor, be called for short: the downlink physical channel of SF)=16, wherein definition has signature sequence.Article one, E-HICH can carry 80 signature sequences, and positive sequence or the antitone sequence of each signature sequence can carry 1 bit information.
For dynamic dispatching E-DCH, a signature sequence of E-HICH can carry a user's confirmation/deny (ACK/NACK) indication, between multiple users, distinguishes by orthogonal signature sequence; For non-dynamic dispatch E-DCH, one group of signature sequence of E-HICH comprises 4 signature sequences.
About concrete mapping mode will be elaborated in subsequent content.
Wherein, described periodicity sends the relevant parameter that parameter refers to that subscriber equipment is used in the time independent intermediate code sequence being carried out to periodically up transmission, for example, and the deviant of idle independent intermediate code sequence etc.The concrete mode that issues will describe in subsequent content.
Concrete adjustment process will describe in subsequent embodiment.
Described in the present embodiment, method has realized up channel has been carried out to close-loop power control by the mapping relations of TPC command word and E-HICH signature sequence, has reduced its interference to other channels; And without the power control result with reference to HS-SICH, be therefore applicable to too periodically send in the technology of independent intermediate code sequence.
Introduce in detail below in the time that described upward signal is independent intermediate code sequence the concrete mapping mode improving in step 103:
In the time that TPC command word is only fed back to subscriber equipment in base station, this TPC command word can be mapped as to a signature sequence in E-HICH.
Particularly, can be according to formula r=16 (t
0-1)+(k-1) [16/K] carry out described mapping, wherein, the numbering that r is described signature sequence, t
0for the numbering of ascending time slot, k is displacement (shift) numbering of described independent intermediate code sequence, and K is the default parameters of described independent intermediate code sequence.After above-mentioned mapping, the mapping relations of the numbering of signature sequence and TPC command word are as shown in table 1:
Table 1
| The numbering of signature sequence | TPC command word |
| 0 | “DOWN” |
| 1 | “UP” |
When base station not only to subscriber equipment feedback TPC command word but also feed back simultaneous bias (Synchronization Shift, be called for short: SS) adjust when command word, described TPC command word and the SS that generated by described base station are adjusted to command word and be jointly mapped as one group of signature sequence in described E-HICH.
Particularly, can be according to formula
carry out described mapping, wherein, r ' is the numbering of described one group of signature sequence, and n is the number of the signature sequence that comprises in every group of signature sequence.After above-mentioned mapping, the mapping relations of the numbering of signature sequence and TPC command word are as shown in table 2:

| 1 | “UP” | “DOWN” |
| 2 | “DOWN” | “UP” |
| 3 | “UP” | “UP” |
| 4 | “DOWN” | “Do Nothing” |
| 5 | “UP” | “Do Nothing” |
Wherein, in TPC command word, " DOWN " represents the transmitting power of the up channel that reduces subscriber equipment, and " UP " represents the transmitting power of the up channel of rising subscriber equipment; Adjust in command word at SS, " DOWN " represents skew backwards, and " UP " represents skew forward, and " Do Nothing " represents not to be offset.
In addition, for compatible mutually with existing non-dynamic dispatch E-DCH signature sequence group form, can make every group of signature sequence comprise 4 signature sequences, but only use wherein 3 for feeding back TPC/SS, a user's ACK/NACK indication is passed into disuse or can be carried to another one signature sequence.
As shown in Figure 2, E-HICH comprises 8 VB vacancy bit positions, and VB vacancy bit value is undefined.The power of each user's ACK/NACK indication can be arranged respectively by base station (Node B).The E-HICH number of each community, i.e. code channel number, can be configured by base station system, and the ACK/NACK indication of dispatching services and non-dynamic dispatching services sends respectively on different E-HICH.
Feed back to subscriber equipment by described TPC command word and the SS that generated by described base station being adjusted to one group of signature sequence that command word is mapped as in described E-HICH jointly, make base station in realizing power control, also complete the adjustment to simultaneous bias, thereby improved the operating efficiency of base station.
