Embodiment

With reference to figure 1, this figure is the Radio interface protocols layer schematic diagram that enhanced uplink special physical channel of the present invention is used.

According to the protocol specification of 3GPP, the Radio interface protocols layer of WCDMA is divided into three layers.As shown in Figure 1, the bottom is a physical layer, and the protocol layer that is positioned on the physical (L1) is called data link layer (L2) and network layer (L3).In UTRA FDD wave point, data link layer is divided into several sublayers.On control plane, data link layer (L2) comprises two sublayers---medium access control (MAC) agreement and Radio Link control (RLC) agreement; On user plane, except MAC and RLC, also have two agreements relevant with specific transactions: packet data convergence protocol (PDCP) and broadcast/group broadcast control protocol (BMC), enhanced uplink special physical channel of the present invention promptly belongs to physical layer channel.

Also please refer to shown in Figure 1ly, on interface layer, circle is represented communication service access point (SAP) end to end.SAP between MAC and the physical layer (PHY) provides transmission channel.SAP between RLC and the MAC provides logic channel.Logic channel is divided into two classes: control channel and Traffic Channel.Control channel is used for transmitting control plane information, and Traffic Channel then is used for transmitting user plane information, the corresponding a kind of business of a common Traffic Channel.

With reference to figure 2, this figure is the mapping schematic diagram of above-mentioned various channels, and as shown in the figure, the logic channel that transmits miscellaneous service information or control information at first is mapped to transmission channel, is mapped to corresponding physical channel by transmission channel then and transmits.

Because prior art is when carrying out power control to enhanced uplink special physical channel, gain factor for E-DPDCH and E-DPCCH is all given subscriber equipment by transmitting signaling downwards, cause the waste of high-level signaling, in fact the gain factor of E-DPDCH and E-DPCCH all is relevant with the QoS of business, high-level signaling there is no need the gain factor of two channels of notifying user equipment simultaneously, promptly only need notify the gain factor of one of them channel, the gain factor of another one channel can be by the difference of subscriber equipment by the spreading factor of interchannel, and/or the difference of encoding rate, and/or from the corresponding power of high level configuration additional biasing obtains.

With reference to figure 3, this figure is the preferred embodiment flow chart of enhanced uplink special physical channel Poewr control method of the present invention, mainly may further comprise the steps:

Step 10, network side issue a kind of E-DPDCH reference gain factors β of reference transmission form to subscriber equipment by signaling _{Ed, ref}, the last carrying of E-DPDCH the bias factor δ of the corresponding described reference transmission form of different business channel _iThe power added biasing γ (described γ meaning is to distinguish the receptivity of E-DPCCH and E-DPDCH, promptly different reception Block Error Rates) of (the i representative is mapped to the different business on the same transmission channel) and the corresponding E-DPDCH of E-DPCCH;

δ generally speaking _i=1, for saving signaling, network can not transmit this value.Some is professional owing to require lower propagation delay time or bigger average traffic throughput, can dispose δ _i=2,4,8... is to strengthen through-put power.Like this in the transformat except the size that comprises packet, the bias factor that has also comprised the corresponding reference transmission form of this transformat, this bias factor can be finished the multiplexing back of business data packet notice physical layer by the media access control layer MAC of subscriber equipment, if the MAC layer in multiplexing with the packet multiplexing of a plurality of business in the packet of same transmission channel, MAC can be with wherein higher bias factor as current bias factor notice physical layer.

Step 11, subscriber equipment is determined the corresponding E-DPDCH gain factor that the different business channel of the last carrying of E-DPDCH requires according to the E-DPDCH gain factor of described reference transmission form, described bias factor, during specific implementation, can determine that by calculating E-DPDCH goes up the required corresponding gain factor of other Traffic Channels of carrying by described bias factor subscriber equipment, also be that the gain factor that other Traffic Channels require does not need to transmit by the network high-level signaling again;

For example, subscriber equipment can calculate the E-DPDCH gain factor of the different transformat j correspondence of each different professional i according to following formula:

${\mathrm{\β}}_{\mathrm{ed},i,j}={{\mathrm{\δ}}_i\·\mathrm{\β}}_{\mathrm{ed},\mathrm{ref}}\·\sqrt{\frac{L_{\mathrm{ed},\mathrm{ref}}}{L_{\mathrm{ed},j}}}\·\sqrt{\frac{K_{\mathrm{ed},j}}{K_{\mathrm{ed},\mathrm{ref}}}}$

Wherein:

-β _{Ed, ref}: the E-DPDCH gain factor of reference transmission form

-β _{Ed, i, j}: the E-DPDCH gain factor of the j kind transformat of i kind Traffic Channel

-K _{Ed, j}: j kind transformat E-DPDCH data carried by data bit number.

Need to prove that those skilled in the art also can adopt other formula to calculate according to actual conditions, repeat no more here.

Step 12, the gain factor that corresponding E-DPCCH requires is determined in corresponding gain factor and described additional biasing that the different business channel that subscriber equipment carries according to described definite E-DPDCH requires;

Usually, because in the time of the transmission of the business of higher qos requirement, the power gain factors of E-DPDCH is than higher, require the power gain factors of E-DPCCH also will match with E-DPDCH this moment, otherwise understand the traffic affecting efficiency of transmission, therefore in the gain factor of determining E-DPCCH, should consider the gain factor of current E-DPDCH.

The encoding rate of supposing E-DPDCH is r _Ed, the encoding rate of E-DPCCH is r _Ed, the spreading factor of E-DPDCH is SF _EdIf E-DPDCH divides channel to form by many bar codes, get wherein maximum spreading factor, β _EdAlso be taken as the gain factor of the Code Channel of this spreading factor correspondence.The spreading factor of E-DPCCH is SF _Ec, then can calculate the gain factor of E-DPCCH according to following formula:

${\mathrm{\β}}_{\mathrm{ec}}={\mathrm{\β}}_{\mathrm{ed},i,j}\·\sqrt{\frac{{\mathrm{SF}}_{\mathrm{ed},i,j}}{{\mathrm{SF}}_{\mathrm{ec}}}}\·\sqrt{\frac{r_{\mathrm{ec}}}{r_{\mathrm{ed},i,j}}}\·\mathrm{\γ}$

Or ${\mathrm{\β}}_{\mathrm{ec}}={\mathrm{\β}}_{\mathrm{ed},i,j}\·\sqrt{\frac{{\mathrm{SF}}_{\mathrm{ed},i,j}}{{\mathrm{SF}}_{\mathrm{ec}}}}\·\mathrm{\γ}$

SF _{Ed, i, j}: the spreading factor of E-DPDCH;

SF _Ec: the spreading factor of E-DPCCH;

γ: the power added biasing of the corresponding E-DPDCH of E-DPCCH.

For example, if SF _{Ed, i, j}=16, SF _Ec=256, β _Ed=1, γ=1, r _{Ed, i, j}=0.4, r _Ec=1/3, then calculate according to formula

β _ec＝0.5*0.9128＝0.4564.

Above-mentioned high level can dispose at the different channels environment for the biasing of γ, can not dispose yet, and γ=1 then, in addition, β in this step _EcBe corresponding β _{Ed, i, j}Calculating is determined, for step 11 β definite according to different business _{Ed, i, j}, this step can be determined the β of corresponding various traffic channels equally according to above-mentioned method _Ec, by such method, both the power bias of high speed uplink bag access channel (comprising E-DPCCH and E-DPDCH) and qos requirements such as professional kind and time delay were connected, realized accurate control for wireless traffic QoS.Reduced the expense that signaling is used to transmit the E-DPCH power offset of channel again simultaneously.
