Embodiment 2
Referring to Fig. 3, the embodiment of the present invention provides a kind of transmission power control method, and described method comprises:
Step 201: the current environment information of obtaining multilink;
Wherein, the execution subject of this step is UE.In uplink inner-loop power control, Node B is controlling party, and UE is execution side, under multilink, UE utilizes the soft value of TPC that TPC pooled function γ provides by down link Node B to merge after processing, adjusts the transmitting power of up link according to amalgamation result.
In practical application, situation simultaneously that exist UE to be connected with multilink, although UE sends a uplink data to all Node B on up direction simultaneously, but different because of the wireless propagation environment between UE and different N ode B, UE can receive the TPC order from the down link of different N ode B simultaneously.Now UE need to merge the soft value of TPC from different N ode B, and determines how to adjust the transmitting power of up link according to amalgamation result.
In the embodiment of the present invention, multilink has comprised three kinds of situations: pure R99 link set, pure UPA link set and compounded link collection, wherein, for compounded link collection, mainly refer to the mixing collection of R99 link set and single upstream packet access UPA link set in the present embodiment.The current environment information of the multilink in the present embodiment comprises that multilink is the mixing collection of many R99 link set and single upstream packet access UPA link set, the soft value of TPC of R99 link set and the soft value of TPC of UPA single-link collection, the number of single UPA link set passes the information such as the error rate, and the number biography error rate of single UPA link set refers to that the upper line number of UPA of UE passes the error rate.Wherein, can know that according to the concrete numerical value of the soft value of TPC of link set this link set requires power per liter still to fall power, the soft value of TPC of link set is that random number 0 and 1,0 represents this link set power of will begging to surrender, and 1 represents that this link set requires power per liter.
Step 202: judge whether this current environmental information meets problem scenes, if meet problem scenes, performs step 203, if do not belong to problem scenes, performs step 205;
In this step, this problem scenes specifically refers in the mixing multilink soft handover scenario of many R99 link set and single UPA link set, know that according to the soft value of TPC each R99 link set requires UE to fall power, and single UPA link set requires power per liter, and the number of single UPA link set passes the error rate and is greater than preset value, if the current environment information of obtaining meets this problem scenes, show that current environment information belongs to problem scenes, now according to TPC pooled function γ provided by the invention, this multilink is adjusted.
Particularly, the TPC pooled function γ providing in the embodiment of the present invention comprises the weighted value of the soft value of TPC and the soft value of described TPC of N link set, wherein, in N link set, there are N-1 R99 link and a UPA link, the corresponding weighted value of this list UPA link set, the corresponding weighted value of this N-1 R99 link set, and the weighted value of this list UPA link set is made as k, and the weighted value of this R99 link set is 1.
Wherein, in the time that multilink is the compounded link collection of R99 link set and single UPA link set, UE judges whether current environment information belongs to problem scenes, refer to according to the current environment information of obtaining, judge whether this current environmental information meets the condition of problem scenes, if meet, judge current environment information and belong to problem scenes, if do not meet, judge current environment information and do not belong to problem scenes.
As, when multilink is that many R99 link set and single upstream packet are while accessing the mixing collection of single UPA link set, judge whether current environment information belongs to problem scenes and be specially, whether the number biography error rate that judges the single UPA link set in this current environmental information is greater than preset value, if be greater than, judge current environment information and belong to problem scenes, if be less than, judge current environment information and do not belong to problem scenes.
Step 203: adjust the weighted value of the soft value of TPC of single UPA link set described in TPC pooled function, this weighted value is adjusted into and is greater than initial value;
The embodiment of the present invention is provided with TPC pooled function γ, in the time belonging to problem scenes, by adjusting TPC pooled function γ, makes the amalgamation result of multilink trend towards the soft value requirement of TPC of single UPA link set, meets the requirement of single UPA link set power per liter.
Wherein, TPC pooled function is γ (W
1, W
2... W
n), the link set number that N is multilink, establishes W
1for the soft value of TPC of single UPA link set, the soft value respective weights of this TPC value k, W
2... W
n-1for the soft value of TPC order of R99 link, the initial value of the weighted value of this N-1 link can be made as 1, W
1weighted value larger, the amalgamation result of multilink more tends to the corresponding link TPC of this soft value order.
When UE judges current environment information and belongs to problem scenes, TPC pooled function is adjusted, with according to the TPC pooled function after this adjustment, the amalgamation result of multilink is trended towards to the soft value requirement of TPC of single UPA link set.Concrete method of adjustment is: k value is adjusted into and is greater than initial value, as 1, and pass the error rates according to the number of single UPA link set of Dynamic Acquisition and adjust in real time the size of k value.
Wherein, adjust in real time the size of K value according to the number biography error rate of single UPA link set of Dynamic Acquisition, specifically comprise:
The number of UE Real-time Obtaining list UPA link set passes the error rate, judges that this number passes the error rate and whether increases compared with previous moment, increases if number passes the error rate, tunes up this k value; If misinformation the error rate reduce, turn this k value down, but adjustment after k value be still greater than initial value, as 1.In practical application, the current number biography error rate of single UPA link set and the relation that k refers to can be: the current number biography error rate of single UPA link set is higher, and k value is larger, and the current number biography error rate of single UPA link set is lower, and k value is less, but k is greater than initial value, as 1.For example, can the output error rate of single UPA link set and the relation of k be set to k=Bler × 2
n, wherein, Bler represents that the current number of single UPA link set passes the error rate.
For example, suppose that TPC pooled function γ is achieved as follows, establishing R is amalgamation result:
1) current environmental information comprises that the link set number that the soft value of TPC is initial value is x, and the link set number that the soft value of TPC is 0 is y;
2) x+y=N, N represents the link set sum of multilink;
3) the probability indicated value that certain the amalgamation result soft value of an above-mentioned x+y TPC being merged is 1 is U=x × 1/ (2
n);
4) the probability indicated value that certain the amalgamation result soft value of an above-mentioned x+y TPC being merged is 0 is D=y × 1/2;
5) the cumulative probability indicated value that in the embodiment of the present invention, default amalgamation result is 1 is Uc, and Uc initial value is 0, and the result of Uc+U is composed to Uc, proceeds to accumulate Uc value;
6) in the time of U<D and Uc<D, amalgamation result R is-1, and amalgamation result now shows to fall power;
7) in the time of U>D, amalgamation result R is 1, and amalgamation result now shows power per liter;
8), in the time of Uc>=D, amalgamation result R is 1, by Uc assignment be 0 proceed accumulation;
While belonging to problem scenes, the embodiment of the present invention is adjusted into U: under multilink, and while there is multiple R99 link set, x>=1, now U=(x – 1) × 1/ (2
n)+k × 1/ (2
n)=x × 1/ (2
n)+(k-1) × 1/ (2
n); Therefore, in the time that k is set to be greater than 1 numerical value, known through above-mentioned accumulation, it is higher that the probability of U>D occurs, that is to say power per liter probability occur higher, amalgamation result trends towards power per liter, trends towards the soft value requirement of TPC of single UPA link set.
The embodiment of the present invention provides a kind of TPC pooled function and adjusts the mode of this TPC pooled function, according to the TPC pooled function after adjusting, the soft value of the TPC of multilink is merged the amalgamation result of the soft value requirement of the TPC that trends towards single UPA link set that obtains large probability, thereby UE is according to this amalgamation result control ascending power, improve transmitting power, improved emitting performance.
Step 204: detect when current environmental information has exited problem scenes within the default time, judge whether current environment information belongs to problem scenes, if belong to, perform step 203, otherwise execution step 205.
In this step, detect that current environmental information has exited after problem scenes, judge whether environmental information current within a period of time belongs to problem scenes, if belong to problem scenes, still perform step 203 step, according to the TPC pooled function after adjusting, the TPC value of multilink is merged; If do not belong to problem scenes, perform step 205 step, k=1 is set.Wherein, this default time can be arbitrary value, and the present invention does not limit at this.
Step 205: the weighted value of the soft value of TPC of the single UPA link set in multilink is adjusted into initial value.
In this step, in the time that UE judges current environment information and do not belong to problem scenes, in TPC pooled function now, the weighted value of the soft value of TPC of single UPA link set is initial value, and the weighted value of N link is the initial value of acquiescence.
In addition, the present embodiment provides in the time that multilink is pure R99 link set, now according to TPC pooled function, the soft value of TPC of each R99 link set in described multilink is merged, and according to amalgamation result control uplink transmit power.
