Embodiment one

A kind of flow chart controlling the method for uplink transmission power that Fig. 1 provides for the embodiment of the present invention one.The method can be performed by subscriber equipment or up dispensing device, and this up dispensing device realizes with the method for hardware and/or software usually, and in a user device integrated.As shown in Figure 1, the method for the present embodiment can comprise:

S110, receive transmitted power parameter and the power division parameter of network side transmission, described transmitted power parameter indicates maximum total transmitted power of ascending control channel and uplink data channels, and described power division parameter indicates the transmitted power ratio T/P of described uplink data channels and described ascending control channel;

The channel of the up transmission of UE comprises ascending control channel and uplink data channels, when specific implementation, can in the process of UE access, transmitted power parameter and power division parameter is issued by high-level signaling, to carry out the initial condition of power division to ascending control channel and uplink data channels as UE by network side; Particularly, maximum total transmitted power of ascending control channel and uplink data channels, i.e. the transmitted power sum transmitted power parameter that can issue for network side; Further, power division parameter indicates power ratio (Traffic to Total Pilot Ratio, the abbreviation: T/P) of uplink data channels and ascending control channel; It can thus be appreciated that the transmitted power of maximum total transmitted power, uplink data channels and ascending control channel meets following constraints:

\{\begin{matrix} P_{1} + P_{2} = C \\ \frac{P_{2}}{P_{1}} = \frac{T}{P} \end{matrix} - - - (1)

In above-mentioned (1) formula, C is maximum total transmitted power, P ₁for the transmitted power of ascending control channel, P ₂for the transmitted power of uplink data channels; P ₂with P ₁ratio be the uplink data channels of power division parameter notifications and the power ratio T/P of ascending control channel.

S120, according to described transmitted power parameter, determines current up total transmitted power;

The transmitted power parameter that UE can issue according to network side usually determines total transmitted power of current up transmitting channel, i.e. the transmitted power sum of ascending control channel and uplink data channels; Particularly, up total transmitted power is less than or equal to maximum total transmitted power, specifically meets the following conditions:

C ₁≤C （2）

In above-mentioned (2), C ₁for current up total transmitted power, C is maximum total transmitted power.

In the present embodiment, if transmitted power parameter is not more than UE hold dump power, then determine that up total transmitted power is this transmitted power parameter; If transmitted power parameter is greater than UE hold dump power, then determine that up total transmitted power is that UE holds dump power.

The method of the control uplink transmission power that the present embodiment provides, really customized to illustrate to up total transmitted power, when specific implementation, the minimum value in the dump power of the transmitted power parameter selecting network side to issue and UE end, as the up total transmitted power in practical application.Usual UE end can arrange spendable maximum power, but a part of power may be used for the use of other data in actual applications, such as, use a part of uplink transmission power when UE end carries out voice call, remaining Partial Power is the dump power of UE end, also namely this UE end may be used for total transmitted power of up transmission, therefore, up total transmitted power must be the maximum power that UE end can be used for up transmission; It should be noted that, if when UE holds dump power to be total transmitted power of up transmission, when UE holds dump power to change, up total transmitted power is also need to change.

S130, according to described up total transmitted power and described T/P, controls the transmitted power of described uplink data channels and described ascending control channel respectively, compares SINR with the drying of the reception of described uplink data channels under improving current channel condition letter _d.

According to above-mentioned (1) formula and (2) formula, the power division of uplink data channels and ascending control channel can be carried out to up total transmitted power in the up transmission of UE; Particularly, the T/P that UE issues according to the up total transmitted power determined and reception network side, respectively power division control is carried out to the transmitted power of uplink data channels and ascending control channel, carry out distributing according to this T/P and meet the condition of above-mentioned (1) formula and (2) formula, it can thus be appreciated that the transmitted power of up total transmitted power, uplink data channels and ascending control channel meets following constraints:

\{\begin{matrix} P_{1} + P_{2} = C_{1} \\ \frac{P_{2}}{P_{1}} = \frac{T}{P} \end{matrix} - - - (3)

In above-mentioned (3) formula, C ₁for up total transmitted power, P ₁for the transmitted power of ascending control channel, P ₂for the transmitted power of uplink data channels; P ₂with P ₁ratio be uplink data channels and the power ratio T/P of ascending control channel of power division instruction notice.

It should be noted that, according to described up total transmitted power and described T/P, control the transmitted power of described uplink data channels and described ascending control channel respectively, be exactly under the constraints of (3) formula, optimize the power division between ascending control channel and uplink data channels, the transmitted power of ascending control channel is maintained one and can meet the level that network side carries out the Minimum requirements of channel estimating, namely there is minimum requirements in the transmitted power of network side to ascending control channel, when specific implementation, can by the dry size of transmitted power than reacting ascending control channel of the reception of ascending control channel letter, when the reception letter drying of ascending control channel is larger, namely the transmitted power of current ascending control channel is greater than the minimum requirements of above-mentioned network side to the transmitted power of ascending control channel, then control to distribute relatively little transmitted power to ascending control channel, correspondingly, control making uplink data channels distribute relatively large transmitted power, thus SINR is compared in the reception letter drying improving uplink data channels _d, and then improve the transmission rate of uplink data channels uplink data sending under current channel condition.

Particularly, the power division that described power division parameter is used to indicate described ascending control channel and described uplink data channels is to control the transmission rate of uplink data sending under current channel condition, refer under the power division indicated by power division parameter, control the transmission rate of uplink data sending in up process of transmitting under current channel condition, the SINR that network side obtains can be made _dhigher, the interference be subject to is less.

In specific implementation, UE, when up transmission, is often subject to the up transmission interference of other UE, and in the prior art, UE adopts the method improving local terminal transmitted power to ensure SINR usually _d, the method improving this UE transmitted power in prior art will inevitably cause the coverage rate of subzone network and the reduction of capacity.The method of the control uplink transmission power that the present embodiment provides, UE is according to the constraints in above-mentioned (3), the transmission rate of adjustment uplink data channels, due to T/P value in the present embodiment for power division parameter indicates, under making the condition determined in above-mentioned up total transmitted power, to control the SINR of uplink data channels under current channel condition _d, and then improve the transmission rate of uplink data channels uplink data sending under current channel condition.

The method of the control uplink transmission power that the present embodiment provides, the transmitted power parameter issued by utilizing network side and power division parameter, control the transmitted power of uplink data channels and ascending control channel respectively, to improve the dry ratio of reception letter of uplink data channels under current channel condition, thus the dry ratio of the reception letter that improve uplink data channels under certain up total transmitted power, and then improve the transmission rate of uplink data channels uplink data sending under current channel condition, reduce interference to a certain extent, come anti-interference by improving transmitted power when solving up transmission in prior art, cause the problem that the covering of subzone network and capacity reduce, avoid the waste of uplink transmission resource.

Alternatively, the another kind that Fig. 2 provides for the embodiment of the present invention controls the flow chart of the method for uplink transmission power.In the method for the control uplink transmission power that the present embodiment provides, ascending control channel can comprise the first ascending control channel and the second ascending control channel; S130 is specially: according to the reception Signal to Interference plus Noise Ratio desired value SINR preset described first ascending control channel ₁determine the transmitted power of described first ascending control channel, according to the transmitted power of described first ascending control channel, described up total transmitted power and described T/P, determine described second ascending control channel and described uplink data channels transmitted power separately respectively, wherein, described SINR ₁carry out the threshold value of the letter drying needed for channel estimating than setting according to described network side.With above-described embodiment one similarly, in the present embodiment, the constraints of the transmitted power demand fulfillment of each channel is specially:

\{\begin{matrix} P_{10} + P_{11} + P_{2} = C_{1} \\ \frac{P_{2}}{P_{10} + P_{11}} = \frac{T}{P} \end{matrix} - - - (4)

In above-mentioned (4) formula, C ₁for up total transmitted power, P ₁₀be the transmitted power of the first ascending control channel, P ₁₁be the transmitted power of the second ascending control channel, P ₂for the transmitted power of uplink data channels; The transmitted power P of the first ascending control channel ₁₀by receiving transmitting power control (Transmit Power Control the is called for short TPC) instruction of network side feedback with the reception SINR keeping reception first ascending control channel ₁adjust transmitted power P ₁₀size; P ₂with P ₁₀+ P ₁₁ratio be power division parameter T/P, therefore in above-mentioned formula (4), can according to C ₁, T/P and P ₁₀determine P ₁₁and P ₂size.
