FIG. 4 is a schematic flowchart of an interference processing method according to an embodiment of the present invention. As shown in FIG. 4 , the interference processing method includes the following S401-S406.

S401. The interference processing apparatus determines the interfered time slot that is interfered by the cross link from the multiple uplink time slots.

As a possible implementation manner, the interference processing device acquires the interference value of each uplink time slot in the multiple uplink time slots under the base station, and determines the multiple The interfered time slot in the uplink time slot that is interfered with by the cross link.

In one design, as shown in FIG. 5 , S401 provided by an embodiment of the present disclosure may specifically include the following S4011-S4012.

S4011. The interference processing apparatus acquires interference values of multiple uplink time slots.

The interference value of one uplink time slot is the average value of the received noise power of one uplink time slot within a preset time period.

As a possible implementation manner, the interference processing apparatus acquires the received noise power of each uplink time slot within a preset time period, and calculates an average value of the received noise power of the uplink time slot within the preset time period.

Exemplarily, there are 20 time slots in a system frame, 10 of which are uplink time slots. For the i-th uplink time slot in the 10 uplink time slots, the interference processing apparatus obtains the received noise power of the n i-th uplink time slots in the n system frames within the preset time period, and calculates the n-th uplink time slot. The average value of the received noise power of the i uplink time slots is used as the interference value of the i-th uplink time slot.

The received noise power of each time slot in each system frame is stored in the interference processing device, which may be shown in Table 1 below.

Table 1

Indicator name Collection timestamp i-th uplink time slot of s frame The jth uplink time slot of the s frame Upstream receive noise power (dBm) YY,MM,DD,HH,SS Psi Psj

Among them, Psi is the received noise power of the ith uplink time slot in the sth system frame, and Psj is the received noise power of the jth uplink time slot in the sth system frame.

It should be noted that the collection time stamps in Table 1 above constitute a preset time period for obtaining uplink received noise power.

S4012. The interference processing apparatus determines an interfered time slot from a plurality of uplink time slots based on the obtained interference value and a preset interference threshold value.

As a possible implementation manner, the interference processing apparatus determines, according to the interference values of multiple uplink time slots in the base station, that the uplink time slot whose interference value is greater than the preset interference threshold value is the interfered time slot.

For other possible implementation manners of this step, reference may be made to subsequent descriptions of the embodiments of the present invention, and details are not repeated here.

S402. The interference processing apparatus determines whether the interference value of the interfered time slot is greater than a preset first threshold.

It should be noted that the first threshold may be set in advance by the operation and maintenance personnel in the interference processing device.

Exemplarily, the first threshold may be -95dbm.

S403. In the case that the interference value of the interfered time slot is greater than the first threshold, the interference processing apparatus acquires the service carried on the service channel TCH of the first user equipment UE.

The interfered time slot is used for allocating time slot resources to the TCH of the first UE.

As a possible implementation manner, the interference processing apparatus acquires the QCI level of the TCH of the first UE to determine the service carried on the TCH of the first UE.

Exemplarily, when the QCI level is 1, it indicates that the voice service is carried on the TCH of the first UE.

S404. The interference processing apparatus determines that only the voice service is carried on the TCH of the first UE, or both the voice service and the data service are carried.

As a possible implementation manner, the interference processing apparatus determines, according to the determined QCI, whether only the voice service is carried on the TCH of the first UE, or whether the voice service and the data service are carried simultaneously.

S405. In the case where only the voice service is carried on the TCH of the first UE, the interference processing apparatus determines the uplink of the received power spectrum of the TCH of the first UE according to the initial block error rate of the voice service and the preset first channel configuration parameter power.

The first configuration information includes the target block error rate of the demodulated voice service, the maximum power offset of the received power spectrum of the TCH of the first UE, and the initial power of the received power spectrum of the TCH of the first UE.

As a possible implementation manner, when the TCH of the first UE only carries the voice service, the interference processing device performs the demodulation according to the initial block error rate of the demodulated voice service, the target block error rate in the first channel configuration parameter, and the first The maximum power offset of the received power spectrum of the TCH of the UE is calculated to obtain the target power offset of the received power spectrum of the TCH of the first UE, and further, according to the target power offset and the initial power, the TCH of the first UE is determined. Upstream power of the received power spectrum.

For a specific implementation manner of this step, reference may be made to the subsequent description of the embodiments of the present invention, and details are not repeated here.

S406. In the case where the voice service and data service are carried on the TCH of the first UE, the interference processing apparatus determines the modulation and coding of the TCH of the first UE according to the interference value of the interfered time slot and the preset second channel configuration parameter The target level of the policy MCS.

As a possible implementation manner, the interference processing apparatus calculates the down-regulation bias of the MCS (modulation and coding scheme, MCS) of the TCH of the first UE according to the interference value of the interfered time slot and the preset second channel configuration parameter, And according to the calculated down-regulation bias, the level of the MCS of the TCH of the first UE is adjusted.

For the specific implementation of this step, reference may be made to the subsequent description of the embodiments of the present invention, and details are not repeated here.

It can be understood that, after determining the uplink power of the received power spectrum of the TCH of the first UE or the target level of the MCS, the interference processing apparatus may broadcast the uplink power of the received power spectrum of the TCH of the first UE or the target level of the MCS to the first UE. A UE, so that the first UE sets the TCH of the first UE according to the received uplink power or the target level of the MCS.

Optionally, in order to determine the interfered time slot according to the interference values of multiple uplink time slots, as shown in FIG. 6 , the embodiment of the present invention further provides another implementation manner of S4012, which specifically includes the following S501-S503.

S501. The interference processing apparatus determines the difference between the interference value of the first uplink time slot and the interference value of the second uplink time slot.

Wherein, the first uplink time slot and the second uplink time slot are any one of the multiple uplink time slots.

S502. The interference processing apparatus determines whether the difference between the interference value of the first uplink time slot and the interference value of the second uplink time slot is greater than the first interference threshold, and whether the interference value of the first uplink time slot is greater than the second interference threshold.

The interference threshold includes a first interference threshold and a second interference threshold.

It should be noted that both the first interference threshold and the second interference threshold may be set in advance in the interference processing device by the operation and maintenance personnel.

S503. If the difference between the interference value of the first uplink time slot and the interference value of the second uplink time slot is greater than the first interference threshold, and the interference value of the first uplink time slot is greater than the second interference threshold, the interference processing apparatus determines the first The uplink time slot is the interfered time slot.

Exemplarily, the first uplink time slot is the ith uplink time slot in the multiple uplink time slots, and the second uplink time slot is the jth uplink time slot in the plurality of uplink time slots. Wherein, i and j are both positive integers, and i≤N, j≤N, and N is the number of multiple uplink time slots.

After determining the average value of the received noise power of the ith uplink time slot and the average value of the received noise power of the jth uplink time slot, if the average value of the received noise power of the ith uplink time slot is the same as the average value of the received noise power of the jth uplink time slot The difference between the average values of the received noise powers of the time slots is greater than the first interference threshold, and the average value of the received noise powers of the ith uplink time slot is greater than the second interference threshold, then the ith uplink time slot is determined to be subject to crossover The interfered time slot of the link interference, the average value of the received noise power of the ith uplink time slot is the interference value of the interfered time slot.

In one design, in order to be able to determine the first UE, as shown in FIG. 7 , the interference processing method provided by the embodiment of the present invention further includes the following S601-S602.

S601. The interference processing apparatus determines, from the UEs accessing the base station, a second UE whose TCH occupies a non-interfered time slot.

The non-disturbed time slot includes uplink time slots other than the interfered time slot among the plurality of uplink time slots. In the second UE, the time slot allocation priority of the UE whose path loss is greater than the preset loss threshold is greater than the time slot allocation priority of the UE whose path loss is less than or equal to the loss threshold.

As a possible implementation manner, the interference processing apparatus determines the path loss of all UEs accessing the base station, and divides all UEs accessing the base station into a third UE and a fourth UE based on a preset loss threshold.

Wherein, the path loss of the third UE is greater than the loss threshold, and the path loss of the fourth UE is less than or equal to the preset loss threshold.

It can be understood that the third UE is a UE located at the edge of coverage of the base station, and the fourth UE is a UE located at the center of coverage of the base station.

Further, the interference processing apparatus determines a non-interfered time slot in the multiple uplink time slots, and allocates the time slot resource of the non-interfered time slot to the TCH of the third UE.

In one case, after the interference processing apparatus allocates the time slot resources of the non-disturbed time slots in the multiple uplink time slots to the TCH of the third UE, if there are still remaining time slot resources in the non-disturbed time slots, then The interference processing apparatus allocates the remaining time slot resources to the TCH of the fourth UE until the remaining time slot resources are allocated. So far, the interference processing apparatus allocates the practice resources of the fourth UE to the UEs to which the non-interfered time slot practice resources are not allocated. Determined to be the second UE.

In another case, the interference processing apparatus allocates the time slot resources of the non-interfered time slots in the multiple uplink time slots to the TCH of the third UE, if the time slot resources of the non-interfered time slots are insufficient during the allocation process In order to be the TCH allocated to the third UE, the interference processing apparatus determines the third UE to which the non-interfered time slot resource is not allocated and the fourth UE to be the second UE.

S602. The interference processing apparatus determines that among the UEs accessing the base station, the UEs other than the second UE are the first UE.

In one design, as shown in FIG. 8 , S403 provided by the embodiment of the present invention specifically includes S4031-S4032:

S4031. The interference processing apparatus determines the remaining time slot resources in the non-interfered time slots in the multiple uplink time slots.

The non-disturbed time slot includes uplink time slots other than the interfered time slot among the plurality of uplink time slots.

As a possible implementation manner, the interference processing apparatus determines the non-interfered time slots in the multiple uplink time slots, and determines the remaining time slot resources of the non-interfered time slots.

S4032: In the case that there is no remaining time slot resource in the non-interfered time slot and the interference value of the interfered time slot is greater than the first threshold, the interference processing apparatus acquires the service carried on the service channel TCH of the first user equipment UE.

As a possible implementation manner, the interference processing apparatus obtains the service of the first user equipment UE when it is determined that there are no remaining time slot resources in the non-interfered time slot and the interference value of the interfered time slot is greater than the first threshold Services carried on the channel TCH.

In another case, if the interference processing apparatus determines that there are remaining time slot resources in the non-interfered time slot, the first UE is re-determined according to the implementation manner in the above S601 until there is no remaining time slot in the non-interfered time slot. gap resources.

In one design, in order to be able to determine the uplink power of the received power spectrum of the TCH of the first UE, the first channel configuration parameter involved in the embodiment of the present invention includes the maximum power offset of the received power spectrum of the TCH of the first UE, the solution Adjust the target block error rate of the voice service and the initial power of the received power spectrum of the TCH of the first UE.

In this case, as shown in FIG. 9 , S405 provided by the embodiment of the present invention specifically includes the following S4051-S4052.

S4051. The interference processing apparatus determines a target power offset of the received power spectrum of the TCH of the first UE according to the initial block error rate, the target block error rate, and the maximum power offset.

As a possible implementation manner, the interference processing apparatus demodulates the voice service to obtain the initial block error rate of the voice service, and determines the TCH of the first UE according to the initial block error rate, the target block error rate and the maximum power offset. Target power offset for the received power spectrum.

The target power offset of the received power spectrum of the TCH of the first UE satisfies the following formula 1:

Wherein, P _c is the target down-regulation bias value of the MCS of the TCH of the first UE, P _ch is the maximum power bias, IBLER is the initial block error rate, and IBLER _target is the target block error rate.

Exemplarily, the target block error rate may be 10%.

S4052. The interference processing apparatus adjusts the initial power based on the target power offset to obtain the uplink power of the received power spectrum of the TCH of the first UE.

As a possible implementation manner, the interference processing apparatus determines the sum of the initial power and the target power offset, which is the uplink power of the received power spectrum of the TCH of the first UE.

It can be seen from the above that when only the voice service is carried on the service channel of the first UE, and the uplink time slot receives relatively strong interference (the interference level is greater than the first threshold), the characteristics of the voice service (continuous small packet traffic) can be used according to the characteristics of the voice service. , and adjust the uplink transmit power of the TCH of the first UE. In order to reduce the overhead of the traffic channel, semi-persistent scheduling is generally used to adjust the transmit power of the traffic channel to reduce interference and improve the reliability of the access network equipment. However, the transmit power of the TCH of the first UE cannot be greatly increased. If the transmit power of the TCH of the first UE is increased significantly, other indicators (eg, network speed) will be affected. Therefore, conservative adjustment is required for the adjustment of the transmission power of the TCH of the first UE, and the adjusted transmission power of the traffic channel does not exceed the preset range of the communication system.

In one design, in order to be able to determine the target level of the adjusted MCS of the TCH of the first UE, the second channel configuration parameter involved in this embodiment of the present invention includes a preset second threshold, the MCS level of the TCH of the first UE The minimum down-regulation bias of , the maximum down-regulation bias of the MCS level of the TCH of the first UE, and the initial level of the MCS of the TCH of the first UE.

It should be noted that the second threshold, the minimum down-regulation bias, and the maximum down-regulation bias can all be set in advance in the interference processing device by the operation and maintenance personnel. The second threshold is greater than the first threshold.

In this case, as shown in FIG. 10 , S406 provided by the embodiment of the present invention specifically includes the following S4061-S4064.

S4061. The interference processing apparatus determines the magnitude relationship between the interference value of the interfered time slot and the first threshold and the second threshold.

S4062. In the case where the interference value of the interfered time slot is between the first threshold and the second threshold, the interference processing device is based on the interference value of the interfered time slot, the first threshold, the second threshold, the minimum down-regulation offset and the maximum Down bias, determining the target down bias of the MCS of the TCH of the first UE.

As a possible implementation manner, the target down-regulation bias of the MCS of the TCH of the first UE satisfies the following formula 2:

The Offset _mcs is the target down-regulation offset value of the MCS of the TCH of the first UE. M _l is the minimum down bias. M _h is the maximum down bias. P _SM is the first threshold. P _SN is the second threshold. [] is the round-down operation.

It should be noted that the above M _l , M _h , P _SM , and P _SN are all preset by the operation and maintenance personnel according to the actual situation. Exemplarily, M _l may be 2, and M _h may be 25. P _SM can be -95dBm and P _SN can be -75dBm.

S4063. In the case that the interference value of the interfered time slot is greater than the second threshold, the interference processing apparatus determines that the above-mentioned maximum down-regulation bias is the target down-regulation bias of the MCS of the TCH of the first UE.

S4064. The interference processing apparatus adjusts the initial level based on the target down-adjustment offset, so as to obtain the target level of the adjusted MCS of the TCH of the first UE.

As a possible implementation manner, the interference processing apparatus determines the difference between the initial level and the target down-regulation bias as the target level of the adjusted MCS of the TCH of the first UE.

It can be understood that when the uplink time slot receives relatively strong interference (the interference level is greater than the first threshold and less than or equal to the second threshold), the interference can be reduced by reducing the level of the modulation and coding mode of the TCH of the first UE, and Improve the reliability of access network equipment. However, the modulation and coding level of the TCH of the first UE cannot be greatly lowered. If the modulation and coding level of the TCH of the first UE is greatly lowered, other indicators (eg, network speed) will be affected. Therefore, conservative adjustment is required for the adjustment of the MCS level of the TCH of the first UE, and the modulation and coding level of the TCH of the first UE after adjustment is at least 0.

In one design, the interference processing method provided by the embodiment of the present invention further provides a method for adjusting the uplink power of the received power spectrum of the TCH of the first UE, which specifically includes the following S801-S804.

S801. The interference processing apparatus determines the magnitude relationship between the interference value of the interfered time slot and the third threshold and the fourth threshold.

It should be noted that the third threshold and the fourth threshold may be pre-set in the interference processing device by the operation and maintenance personnel. The fourth threshold is greater than the third threshold.

S802. When the interference value of the interfered time slot is between the first threshold and the second threshold, the interference processing apparatus determines, according to the interference value of the interfered time slot and the third channel configuration parameter, the reception of the TCH of the first UE Target power offset for the power spectrum.

The third channel configuration parameter includes the minimum power offset of the received power spectrum of the TCH of the first UE, the maximum power offset of the received power spectrum of the TCH of the first UE, and the initial power of the received power spectrum of the TCH of the first UE .

It should be noted that both the minimum power offset and the maximum power offset can be set in the interference processing device in advance by the operation and maintenance personnel.

As a possible implementation manner, the interference processing apparatus calculates the target of the received power spectrum of the TCH of the first UE according to the interference value of the interfered time slot, the minimum power offset, the maximum power offset, the first threshold, and the second threshold power bias.

The target power offset of the received power spectrum of the TCH of the first UE satisfies the following formula 3:

Wherein, P _c is the target bias power of the received power spectrum of the TCH of the first UE. P _cl is the minimum power offset, P _ch is the maximum power offset, P _SL is the first threshold, P _SH is the second threshold, and P _i is the interference value of the ith interfered time slot in the multiple time slots.

It should be noted that the above P _cl , P _ch , and P _SH are all preset by the operator according to the actual situation. Exemplarily, P _cl may be 2dB. _Pch may be 10dB. _PSH can be -95dBm.

S803. In the case that the interference value of the interfered time slot is greater than the second threshold, the interference processing apparatus determines that the above-mentioned maximum power offset is the target power offset of the received power spectrum of the TCH of the first UE.

S804. The interference processing apparatus adjusts the initial power based on the target power offset, so as to obtain the target power of the adjusted received power spectrum of the TCH of the first UE.

As a possible implementation manner, the interference processing apparatus determines the sum of the target power offset and the initial power, which is the target power of the TCH-adjusted received power spectrum of the first UE.

It can be understood that when the uplink time slot of the interference processing apparatus receives relatively strong interference (that is, the interference level is greater than the third threshold and less than or equal to the fourth threshold), the interference processing apparatus can increase the TCH reception of the first UE by increasing the interference level. The spectrum power is used to reduce interference, but the power of the received power spectrum of the TCH of the first UE cannot be increased indefinitely. If the power is continuously increased, other indicators (eg, network speed) will be affected. Therefore, the power of the received power spectrum of the TCH of the first UE needs to be adjusted within a certain range, and the adjusted power cannot exceed the maximum power of the received power spectrum of the TCH of the first UE.
