Embodiment three
The transmit power controlling method that the embodiment of the present invention three provides to be applicable to WCDMA system, specifically be applicable to by UE in WCHMA system up-link for perform transmitting power control.
If when total transmitting power of UE in WCDMA system exceedes the maximum threshold of transmitting power, when being configured with the E-DCH comprising E-DPDCH and E-DPCCH, UE is in order to reduce total transmitting power, first the gain factor of E-DPDCH is reduced, along with the reduction of the gain factor of E-DPDCH, DTX state may can be in by part or all of E-DPDCH.DTX is discontinuous transmission, and such as, in a communication process, user only has little time for call, and in order to save system resource and reduce intrasystem interference, in gap, the phase does not send message, and sends comfortable noise.Due in the prior art, no matter what state E-DPDCH is in, and E-DPCCH can continue send, and if all E-DPDCH are in DTX state, receiving terminal just still can continue E-DPCCH to be detected, causes E-DPDCH and E-DPCCH asynchronous.Noise in E-DPDCH can be considered as useful data by receiving terminal, thus produces and noise is integrated with useful data carry out demodulation, affects the problem of the demodulation performance of E-DPDCH.The technical scheme that the embodiment of the present invention provides can head it off.
There is different situations in the channel configuration of UE, wherein the channel of UE is at least configured with DPCCH, can there is the situation of single carrier or multicarrier.When single carrier, the configuration of DPDCH and E-DCH is all optional, if be wherein configured with E-DCH, be and be configured with E-DPDCH and E-DPCCH.In addition, UE can also collocating uplink high-speed dedicated control channel HS-DPCCH.
According to the different configuring conditions of UE upper signal channel, the condition reducing total transmitting power in power control process is not identical yet, particularly:
Can judge whether to be configured with DPDCH;
When being configured with DPDCH, reduce the gain factor of E-DPDCH, judge whether the power ratio of E-DPDCH and DPCCH is less than the threshold value of power ratio, if not, then current power control period terminates, and can enter next power control period; If so, then detect E-DPDCH and whether be in DTX state; If all E-DPDCH are in DTX state, then E-DPCCH is placed in DTX state, or, if at least one E-DPDCH is in DTX state, then all E-DPDCH is in DTX state, and E-DPCCH is placed in DTX state.Judge the maximum threshold whether total transmitting power exceeds described transmitting power further, if still exceed the maximum threshold of transmitting power, when the power ratio of the power ratio and HS-DPCCH and DPCCH that keep DPDCH and DPCCH is constant, reduce total transmitting power.
When not configuring DPDCH, reduce the gain factor of E-DPDCH, judge the power ratio of E-DPDCH and DPCCH whether be less than power ratio threshold value; If not, then current power control period terminates, and can enter next power control period; If so, then the power ratio of E-DPDCH and DPCCH is set to the threshold value of power ratio; And judge whether total transmitting power exceeds the maximum threshold of transmitting power further, if still exceed the maximum threshold of transmitting power, then, when keeping the power ratio of HS-DPCCH and DPCCH constant, reduce total transmitting power.
Wherein, when UE does not configure DPDCH, the power ratio of E-DPDCH and DPCCH can not lower than the threshold value of power ratio, if so during the threshold value of the power ratio of E-DPDCH and DPCCH lower than power ratio, then the power ratio of E-DPDCH and DPCCH is set to the threshold value equaling power ratio.
In the present embodiment, the threshold value of power ratio is get minimum of a value in the power ratio of E-DPDCH and DPCCH before the ratio of high level configuration and the gain factor of reduction E-DPDCH, or the threshold value of power ratio is the minimum of a value in preset table.Wherein, the ratio of high-rise configuration can be the power ratio of high-rise minimum E-DPDCH and the DPCCH according to circumstances configured; Minimum of a value in preset table can be the minimum of a value in E-DPDCH and DPCCH ratio form.When UE configures DPDCH, the threshold value of power ratio adopts the minimum of a value in E-DPDCH and DPCCH ratio form; When not configuring DPDCH at UE, the threshold value of power ratio adopts in the power ratio of E-DPDCH and DPCCH before the ratio of high level configuration and the gain factor of reduction E-DPDCH gets minimum of a value.
For the operating system of reality, local channel configuring condition due to UE is acquiescence, such as be defaulted as single carrier or be configured with E-DCH, so need not perform above-mentioned various configuration determination operations completely, which judgement operation of concrete execution can set according to the default configuration situation of UE.The present embodiment is not for all having pre-configured situation to provide complete and preferred process, and as shown in Figure 3, this transmit power controlling method comprises idiographic flow:
Step 301, UE detect the maximum threshold whether total transmitting power is greater than transmitting power in current power control cycle, if so, then perform step 302; If not, current power control cycle terminates, and enters next power control period;
The embodiment of the present invention is paid close attention to and is reduced channel gain factors to the control of total transmitting power, do not conflict between other Poewr control methods adopted with UE, such as, also can adopt other Poewr control method when performing the power control process of the embodiment of the present invention;
Power controls to carry out according to the cycle of setting, in each cycle, carry out power detection and control.The present embodiment, to complete power control process in one cycle, is understandable that, also just may can complete power control process through multiple all after dates.
Step 302, UE judge whether self is configured with E-DCH, if be configured with E-DCH, when self is configured to single carrier, then perform step 303; If non-configuring E-DCH, perform step 309;
Step 303, UE judge whether self is configured with DPDCH, if so, then perform step 304, otherwise perform step 310;
When UE is configured with E-DCH, when single carrier is configured with DPDCH, carries out step 304-309 below, be specially:
Step 304, UE reduce the gain factor of E-DPDCH;
In the present embodiment, can carry out power control according to giving the gain factor of UE channel configuration, therefore gain factor also can be described as power bias.
Step 305, judge whether the power ratio of E-DPDCH and described DPCCH is less than the threshold value of power ratio, if so, then perform step 306; If not, then current power control cycle terminates;
In this step, the threshold value of power ratio is the minimum of a value in E-DPDCH and DPCCH ratio form.
Step 306, UE detect E-DPDCH and whether are in DTX state, if so, then perform step 307, if not, then perform step 308.
If all E-DPDCH of step 307 are in DTX state, E-DPCCH is placed in DTX state by UE; Or if at least one E-DPDCH is in DTX state, all E-DPDCH are placed in DTX state by UE, and E-DPCCH is placed in DTX state;
In above-mentioned steps 304 to 307, the unified gain factor reducing all E-DPDCH of UE; But and not all E-DPDCH can be in DTX state, each E-DPDCH can enter DTX state selectively based on respective strategy and situation; Or E-DPDCH can control according to unified after a certain data channel is in DTX state, namely after at least one E-DPDCH is in DTX state, be placed in DTX state by unified for other E-DPDCH.
Step 308, UE judge whether total transmitting power exceeds the maximum threshold of transmitting power, and if so, then perform step 309, if not, then current power control cycle terminates;
Step 309, UE reduce total transmitting power.
In this step, UE is when the power ratio of the power ratio and HS-DPCCH and DPCCH that keep E-DPDCH and DPCCH is constant, and reduce total transmitting power, after total transmitting power is lower than the maximum threshold of transmitting power, current power control cycle terminates.
When UE is configured with E-DCH, when single carrier does not configure DPDCH, carry out step 310-312 below, be specially:
Step 310, UE reduce the gain factor of E-DPDCH;
Step 311, UE judge whether the power ratio of E-DPDCH and described DPCCH is less than the threshold value of power ratio, if so, then perform step 312, otherwise current power control cycle terminate;
In this step, the threshold value of power ratio is get minimum of a value in the power ratio of described E-DPDCH and DPCCH before the ratio of high level configuration and the gain factor of the described E-DPDCH of reduction.
Step 312, the power ratio of E-DPDCH and DPCCH is set to the threshold value of power ratio, then perform step 308-309, namely UE judges whether total transmitting power exceeds the maximum threshold of transmitting power, if still exceed the maximum threshold of transmitting power, UE reduces total transmitting power.Be configured with at UE DPDCH unlike, when UE does not configure DPDCH, only when keeping the power ratio of HS-DPCCH and DPCCH constant, total transmitting power need be reduced, after total transmitting power is lower than the maximum threshold of transmitting power, current power control cycle terminates.
In the present embodiment, the order of above-mentioned steps 301-312 is preferred sequence, to those skilled in the art, also has other realization order.Such as in the present embodiment, just reduce the gain factor of E-DPDCH after judging whether to configure DPDCH and judge whether the power ratio of E-DPDCH and DPCCH is less than the threshold value of power ratio, in other realization order, also first can reduce the gain factor of E-DPDCH and judge whether the power ratio of E-DPDCH and DPCCH is less than the threshold value of power ratio, judge whether again to configure DPDCH, or in the case of a single carrier, first judge whether to configure DPDCH, then judge whether configuring E-DCH etc.Also have other realization order, do not repeat one by one at this.
Exceed in the power control process of the maximum threshold of transmitting power in the present embodiment in total transmitting power, by when all E-DPDCH are in DTX state, E-DPCCH is also placed in DTX state, or, when at least one E-DPDCH is in DTX state, all E-DPDCH are placed in DTX state, and E-DPCCH is also placed in DTX state, so, solve E-DPDCH and E-DPCCH asynchronous, cause receiving terminal that the noise in E-DPDCH is considered as useful data, thus noise is integrated with the problem that useful data carries out demodulation by generation, ensure the demodulation performance of E-DPDCH.
