Example 1

Referring to FIG. 2, an embodiment of the present invention provides a transmission power control method, the method comprising:

Step 101: Obtain the current environment information of the multi-link, the current environment information at least includes the TPC soft value of each link set in the multi-link, and/or, the first data transmission of the number of UPA link sets in the multi-link bit error rate;

Among them, according to the specific value of the TPC soft value of the link set, it can be known whether the link set requires a power increase or a power reduction. The TPC soft value of the link set is a random number 0 and 1. 0 indicates that the link set requires power reduction. 1 indicates that the link set requires power up.

Step 102: When the multi-link is a hybrid link set of an R99 link set and a single UPA link set, determine whether the current environment information belongs to a problem scenario. The problem scenario specifically includes: R99 link set requires power reduction, single UPA link set The link set requires an increase in power, and the bit error rate of the first data transmission is greater than the preset value;

In practical applications, according to the threshold set by the network side, the preset value of the digital transmission bit error rate of a single UPA link set can be set to any value greater than 6% and less than 15%, such as 10%, etc., the embodiment of the present invention is not correct The specific value of the bit error rate of the digital transmission is limited, and the specific value can be adjusted appropriately according to the threshold set on the network side.

Step 103: If the current environment information belongs to the problem scenario, adjust the weight of the TPC soft value of the single UPA link set in the TPC merging function, and adjust the TPC soft value of each link set of the multi-link after adjustment Merging is carried out so that the merging result of the TPC merging function satisfies the requirement of single UPA link set rising power;

Step 104: Adjust the power of the inner loop according to the combination result to control the uplink transmission power.

In the method provided by the embodiment of the present invention, the weight value of the TPC soft value of the single UPA link set in the multi-link is adjusted to be greater than the initial value, so that the combined result of the multi-link tends to be closer to the TPC soft value of the single UPA link set. value requirements, so that there is a high probability of increasing the power, improving the bit error rate of the uplink transmission of a single UPA link set in the multi-link, increasing the transmission power, improving the transmission performance, and reducing the number of wireless transmissions caused by the maximum number of transmissions of business data. The transmission link is interrupted.

Example 2

Referring to FIG. 3, an embodiment of the present invention provides a transmission power control method, the method comprising:

Step 201: Obtain current environment information of multiple links;

Wherein, the execution subject of this step is UE. In the uplink inner loop power control, the Node B is the controller, and the UE is the executor. Under multi-link, the UE uses the TPC combining function γ to combine the TPC soft values given by the Node B through the downlink. , and adjust the transmit power of the uplink according to the combination result.

In practical applications, there are situations where a UE is connected to multiple links at the same time. Although the UE sends a copy of uplink data to all Node Bs in the uplink direction at the same time, the wireless propagation environment between the UE and different Node Bs is different. , the UE will simultaneously receive downlink TPC commands from different Node Bs. At this time, the UE needs to combine the TPC soft values from different Node Bs, and decide how to adjust the uplink transmit power according to the combined results.

In the embodiment of the present invention, multi-link includes three situations: pure R99 link set, pure UPA link set and mixed link set, wherein, in this embodiment, the mixed link set mainly refers to the R99 link A mixed set of sets and single uplink packet access UPA link sets. The current environment information of the multi-link in this embodiment includes that the multi-link is a mixed set of multiple R99 link sets and a single uplink packet access UPA link set, the TPC soft value of the R99 link set and the UPA single link set The TPC soft value, the data transmission bit error rate of a single UPA link set, and other information. The digital transmission bit error rate of a single UPA link set refers to the UE's UPA uplink data transmission bit error rate. Among them, according to the specific value of the TPC soft value of the link set, it can be known whether the link set requires a power increase or a power reduction. The TPC soft value of the link set is a random number 0 and 1. 0 indicates that the link set requires power reduction. 1 indicates that the link set requires power up.

Step 202: Judging whether the current environment information satisfies the problem scenario, if it satisfies the problem scenario, execute step 203, and if it does not belong to the problem scenario, execute step 205;

In this step, the problem scenario specifically refers to the hybrid multi-link soft handover scenario of multiple R99 link sets and a single UPA link set. According to the TPC soft value, it is known that each R99 link set requires the UE to reduce power, while the single UPA link set The UPA link set requires an increase in power, and the data transmission bit error rate of a single UPA link set is greater than a preset value. If the acquired current environment information meets the problem scenario, it indicates that the current environment information belongs to the problem scenario. At this time, according to the present invention The provided TPC combining function γ adjusts for this multi-link.

Specifically, the TPC combining function γ provided in the embodiment of the present invention includes the TPC soft values of N link sets and the weight values of the TPC soft values, where there are N-1 R99 links in the N link sets and a UPA link, the single UPA link set corresponds to a weight value, the N-1 R99 link sets correspond to a weight value, and the weight value of the single UPA link set is set to k, the R99 link set has a weight of 1.

Wherein, when the multi-link is a mixed link set of R99 link set and single UPA link set, the UE judges whether the current environment information belongs to the problem scenario, which refers to judging whether the current environment information satisfies If the condition of the problem scene is satisfied, it is judged that the current environment information belongs to the problem scene, and if it is not satisfied, it is judged that the current environment information does not belong to the problem scene.

For example, when the multi-link is a mixed set of multiple R99 link sets and a single uplink packet accessing a single UPA link set, to determine whether the current environment information belongs to the problem scenario is to determine the single UPA link in the current environment information Whether the data transmission bit error rate of the set is greater than the preset value, if it is greater, it is judged that the current environmental information belongs to the problem scene, and if it is less, it is judged that the current environmental information does not belong to the problem scene.

Step 203: Adjust the weight value of the TPC soft value of the single UPA link set in the TPC merging function, and adjust the weight value to be greater than the initial value;

In the embodiment of the present invention, the TPC combining function γ is set. When it belongs to the problem scenario, by adjusting the TPC combining function γ, the combined result of the multi-link tends to the TPC soft value requirement of the single UPA link set, that is, the single UPA link is satisfied. Set liter power requirements.

Among them, the TPC combining function is γ(W ₁ , W ₂ ,…W _N ), N is the number of multi-link link sets, W ₁ is the TPC soft value of a single UPA link set, and the TPC soft value corresponds to The weight value k, W ₂ ,...W _N-1 is the TPC command soft value of the R99 link, the initial value of the weight value of the N-1 links can be set to 1, the greater the weight value of W ₁ , the more chain The combination result of the way is more inclined to the link TPC command corresponding to the soft value.

When the UE determines that the current environment information belongs to the problem scenario, it adjusts the TPC combining function, so that the combined result of the multi-links tends to approach the TPC soft value requirement of a single UPA link set according to the adjusted TPC combining function. The specific adjustment method is: adjust the value of k to be greater than the initial value, such as 1, and adjust the value of k in real time according to the dynamically obtained bit error rate of the digital transmission of the single UPA link set.

Among them, the value of K is adjusted in real time according to the bit error rate of the digital transmission of the single UPA link set obtained dynamically, specifically including:

The UE obtains the data transmission bit error rate of a single UPA link set in real time, and judges whether the data transmission bit error rate has increased compared with the previous moment. If the data transmission bit error rate increases, increase the value of k; If the bit error rate decreases, the value of k is reduced, but the adjusted value of k is still greater than the initial value, such as 1. In practical applications, the relationship between the current data transmission bit error rate of a single UPA link set and the k finger can be: the higher the current digital transmission bit error rate of a single UPA link set, the larger the k value, and the The lower the bit error rate of the current digital transmission, the smaller the value of k, but k is greater than the initial value, such as 1. For example, the relationship between the output bit error rate of the single UPA link set and k can be set as k=Bler×2 ^N , where Bler represents the current digital transmission bit error rate of the single UPA link set.

For example, suppose the TPC merging function γ is implemented as follows, let R be the merging result:

1) The current environment information includes x as the number of link sets whose TPC soft value is the initial value, and y as the number of link sets whose TPC soft value is 0;

2) x+y=N, N represents the total number of multi-link link sets;

3) The probability indicating value of a certain combination result of 1 for the combination of the above x+y TPC soft values is U=x×1/(2 ^N );

4) The probability indication value of a combination of the aforementioned x+y TPC soft values being 0 is D=y×1/2;

5) In the embodiment of the present invention, the cumulative probability indication value of the preset combination result of 1 is Uc, and the initial value of Uc is 0, and the result of Uc+U is assigned to Uc, and the accumulated Uc value is continued;

6) When U<D and Uc<D, the combined result R is -1, and the combined result at this time indicates that the power is reduced;

7) When U>D, the merged result R is 1, and the merged result at this time indicates the power increase;

8) When Uc>=D, the combined result R is 1, and Uc is assigned a value of 0 to continue accumulation;

When it belongs to the problem scenario, the embodiment of the present invention adjusts U to: under multi-link, when there are multiple R99 link sets, x>=1, at this time U=(x–1)×1/(2 ^N )+k ×1/(2 ^N )=x×1/(2 ^N )+(k-1)×1/(2 ^N ); therefore, when k is set to a value greater than 1, it can be seen from the above accumulation that U>D The probability of occurrence is relatively high, that is to say, the probability of power increase is relatively high, and the combined result tends to increase power, that is, tends to the TPC soft value requirement of a single UPA link set.

Embodiments of the present invention provide a TPC combination function and a method for adjusting the TPC combination function. According to the adjusted TPC combination function, the TPC soft values of multiple links are combined to obtain a TPC soft value tending to a single UPA link set with a high probability. The combination result required by the value, so that the UE controls the uplink power according to the combination result, increases the transmission power, and improves the transmission performance.

Step 204: When it is detected that the current environment information exits the problem scene, judge whether the current environment information belongs to the problem scene within a preset time, if so, go to step 203, otherwise go to step 205.

In this step, after detecting that the current environmental information exits the problem scene, it is judged whether the current environment information belongs to the problem scene within a period of time, if it belongs to the problem scene, the step of step 203 is still performed, according to the adjusted TPC merge function Merge the TPC values of multiple links; if it does not belong to the problem scenario, perform step 205 and set k=1. Wherein, the preset time may be any value, which is not limited in the present invention.

Step 205: Adjust the weight value of the TPC soft value of the single UPA link set in the multi-link to the initial value.

In this step, when the UE judges that the current environment information does not belong to the problem scenario, in the TPC combination function at this time, the weight value of the TPC soft value of the single UPA link set is the initial value, that is, the weight values of the N links are equal to is the default initial value.

In addition, this embodiment provides that when the multi-link is a pure R99 link set, the TPC soft value of each R99 link set in the multi-link is combined according to the TPC combination function at this time, and the control is performed according to the combined result. Uplink transmission power.

In addition, this embodiment provides that when the multi-link is a pure single UPA link set, the TPC soft value of each single UPA link set in the multi-link is combined according to the TPC combination function at this time, and according to the combination The result controls the uplink transmit power.

In the method provided by the embodiment of the present invention, the weight value of the TPC soft value of the single UPA link set in the multi-link is adjusted to be greater than the initial value, so that the combined result of the multi-link tends to be closer to the TPC soft value of the single UPA link set. Therefore, there is a high probability of a TPC command to increase the power, which improves the bit error rate of the UPA link in the multi-link, increases the transmission power, improves the transmission performance, and reduces the occurrence of wireless transmission due to the maximum number of transmissions of business data. When the data transmission link is interrupted.
