Technical Field

The present application relates to the field of communication technology, and in particular to a PDCCH channel load evaluation method, device and electronic device.

Background technique

Currently, the communication system enables the physical downlink control channel (PDCCH) space division resource scheduling function.

The Physical Downlink Control Channel (PDCCH) mainly carries control information such as uplink and downlink CCE, and schedules uplink service channel and downlink service channel resources respectively to ensure the user's uplink and downlink service perception experience. In the existing PDCCH scheduling process, the time-frequency domain CCE resources are mainly allocated; at the same time, in the process of measuring the PDCCH resource load, only the occupancy of the time-frequency domain CCE resources is evaluated. Considering the introduction of large-scale antennas in 5G and the significant improvement of space division capabilities, the impact of space division multiplexing needs to be considered in the allocation and measurement of physical downlink control channel resources.

The embodiment of the present application provides a physical downlink control channel resource measurement algorithm based on space division multiplexing to accurately measure the PDCCH load and guide subsequent 5G network capacity planning.

The following, in combination with the accompanying drawings, describes in detail the PDCCH channel load assessment method, device and electronic device provided in the embodiments of the present application through some embodiments and their application scenarios.

Step 100, determining the occupied physical downlink control channel PDCCH control channel element CCE resource capacity;

Step 110, determining available PDCCH CCE resource capacity;

Step 120, determining a PDCCH channel utilization rate based on the occupied PDCCH CCE resource capacity and the available PDCCH CCE resource capacity;

Wherein, in the MIMO scenario, the occupied PDCCH CCE resource capacity includes the occupied PDCCH CCE resource capacity in the multiple-input multiple-output MIMO layer scheduled by the current cell, and the available PDCCH CCE resource capacity includes the available PDCCH CCE resource capacity in the available MIMO layer of the current cell;

Specifically, in order to further accurately measure the PDCCH channel load, the PDCCH utilization rate can be calculated based on the actually occupied PDCCH CCE resource capacity and the available PDCCH CCE resource capacity.

For example, in a MIMO scenario, the PDCCH utilization may be calculated based on the occupied PDCCH CCE resource capacity in the multiple-input multiple-output MIMO layer scheduled by the current cell and the available PDCCH CCE resource capacity in the available MIMO layer of the current cell.

For example, in a non-MIMO scenario, the PDCCH utilization rate may be calculated according to the occupied PDCCH CCE resource capacity in the current cell and the available PDCCH CCE resource capacity in the current cell.

Optionally, the PDCCH utilization may be evaluated periodically, for example, in each period, the PDCCH utilization in the current period is calculated based on the PDCCH CCE resource capacity actually occupied in the current period and the PDCCH CCE resource capacity available in the current period.

In order to accurately evaluate the utilization rate of downlink control channel resources, the embodiment of the present application proposes a downlink control channel resource measurement algorithm based on space division multiplexing by introducing the actual number of space layers into the used capacity resources of CCE and the maximum number of available space layers into the available capacity resources of CCE on the basis of the existing downlink control channel resource measurement algorithm, so as to provide technical support for the accurate planning of capacity resources of communication networks such as subsequent 5G networks.

The occupied PDCCH CCE resource capacity is determined based on the number of PDCCH CCEs respectively occupied at each sampling moment in the first period.

Specifically, in a MIMO scenario, the PDCCH utilization can be periodically evaluated. For example, in any first period, the number of PDCCH CCEs occupied by the MIMO layers scheduled at each sampling moment in the current first period can be first determined. Then, based on the number of PDCCH CCEs occupied by the MIMO layers scheduled at each sampling moment in the current first period, the PDCCH CCE resource capacity occupied by the MIMO layers scheduled in the current first period can be calculated, which can be used to calculate the PDCCH utilization in the current first period together with the available PDCCH CCE resource capacity in the current first period.

Specifically, in a non-MIMO scenario, the PDCCH utilization can be periodically evaluated. For example, in any first period, each sampling moment can be traversed to determine the number of PDCCH CCEs occupied at each sampling moment in the current first period. Then, based on the number of PDCCH CCEs occupied at each sampling moment in the current first period, the occupied PDCCH CCE resource capacity in the current first period can be calculated, which can be used to calculate the PDCCH utilization in the current first period together with the available PDCCH CCE resource capacity in the current first period.

Optionally, the length of the first cycle can be 1 minute, or 5 minutes, or 10 seconds, or one hour, or any time length, or any time length set by the user. The embodiment of the present application does not limit this and is not limited here.

The first process includes:

Determining the number of MIMO layers scheduled at the first target sampling time;

Determine the number of PDCCH CCEs respectively occupied by a single MIMO layer scheduled at the first target sampling time at the first target sampling time;

Determine the number of PDCCH CCEs occupied by the MIMO layer scheduled at the first target sampling time based on the number of PDCCH CCEs respectively occupied by the single MIMO layer scheduled at the first target sampling time and the number of layers of the MIMO layer scheduled at the first target sampling time;

The first target sampling time is the sampling time corresponding to the current first process.

Specifically, when determining the number of PDCCH CCEs occupied by the MIMO layers scheduled at each sampling moment in the current first period, the number of PDCCH CCEs occupied by each sampling moment in the first period on a single MIMO layer can be determined first, and then the number of PDCCH CCEs occupied by the MIMO layers scheduled at each sampling moment in the first period can be determined.

For example, at the first sampling moment in the first period, MIMO layers A1, A2, A3, ..., An are scheduled. We can first determine the number a1 of PDCCH CCEs occupied by A1 at the first sampling moment, the number a2 of PDCCH CCEs occupied by A2 at the first sampling moment, the number a3 of PDCCH CCEs occupied by A3 at the first sampling moment, ..., the number an of PDCCH CCEs occupied by An at the first sampling moment; and then we can determine that the number of PDCCH CCEs occupied on the MIMO layers A1, A2, A3, ..., An scheduled at the first sampling moment is a1+a2+a3+...+an. At the second sampling moment in the first period, MIMO layers B1, B2, B3, ..., Bm are scheduled, and the number b1 of PDCCH CCEs occupied by B1 at the second sampling moment, the number b2 of PDCCH CCEs occupied by B2 at the second sampling moment, the number b3 of PDCCH CCEs occupied by B3 at the second sampling moment, ..., and the number bm of PDCCH CCEs occupied by Bm at the second sampling moment can be determined; furthermore, it can be determined that the number of PDCCH CCEs occupied on the MIMO layers B1, B2, B3, ..., Bm scheduled at the second sampling moment is b1+b2+b3+...+bm. By analogy, until the last sampling time in the first cycle is scheduled with MIMO layers Z1, Z2, Z3, ..., Zp, the number of PDCCH CCEs occupied by Z1 at the last sampling time z1, the number of PDCCH CCEs occupied by Z2 at the last sampling time z2, the number of PDCCH CCEs occupied by Z3 at the last sampling time z3, ..., the number of PDCCH CCEs occupied by Zp at the last sampling time zp can be determined; and then the number of PDCCH CCEs occupied by MIMO layers Z1, Z2, Z3, ..., Zp scheduled at the last sampling time z1+z2+z3+...+zp can be determined. That is, the number of PDCCH CCEs occupied by the MIMO layers scheduled at each sampling time in the first cycle is obtained, namely, a1+a2+a3+...+an, b1+b2+b3+...+bm, ..., z1+z2+z3+...+zp.

The embodiment of the present application does not limit this, and it is not limited here. The values of M1 _ij (T) and L _ij (T) can be obtained by the network management system of the communication operator. i represents the i-th user in the first period, and j represents the j-th sampling time in the first period.

Optionally, in a non-MIMO scenario, when calculating the PDCCH CCE resource capacity occupied in the MIMO layer scheduled in the current first period based on the number of PDCCH CCEs respectively occupied at each sampling time in the current first period, the calculation process may be as shown in formula (1):

This can be used to compare the PDCCH CCE resource capacity occupied in the MIMO layer scheduled in the current first period to calculate the PDCCH utilization in the current first period.

Specifically, in a non-MIMO scenario, the PDCCH utilization rate can be periodically evaluated. For example, in any first period, the number of PDCCH CCEs available at each sampling time in the current cell in the first period can be first determined, and then the available PDCCH CCE resource capacity of the current cell can be calculated based on the number of PDCCH CCEs available at each sampling time in the current cell in the first period, which can be used to compare the occupied PDCCH CCE resource capacity in the current first period to calculate the PDCCH utilization rate in the current first period.

For example, within any first period, the number of PDCCH CCEs available at each sampling moment in the available MIMO layer of the current cell within the first period can be determined, and then the available PDCCH CCE resource capacity in the available MIMO layer of the current cell can be calculated based on the number of PDCCH CCEs available at each sampling moment in the available MIMO layer of the current cell within the first period; and the number of PDCCH CCEs occupied by the MIMO layers scheduled at each sampling moment in the current first period can be determined, and then the PDCCH CCE resource capacity occupied in the MIMO layer scheduled in the current first period can be calculated based on the number of PDCCH CCEs occupied by the MIMO layers scheduled at each sampling moment in the current first period; and then the PDCCH utilization rate in the current first period is calculated based on the available PDCCH CCE resource capacity in the available MIMO layer of the current cell and the PDCCH CCE resource capacity occupied in the MIMO layer scheduled in the current first period.

Specifically, in a non-MIMO scenario, the PDCCH utilization rate can be periodically evaluated. For example, within any first period, the number of PDCCH CCEs available at each sampling moment in the current cell within the first period can be determined, and then the available PDCCH CCE resource capacity of the current cell can be calculated based on the number of PDCCH CCEs available at each sampling moment in the first period of the current cell; and the number of PDCCH CCEs occupied at each sampling moment in the current first period can be determined, and then the PDCCH CCE resource capacity occupied in the current first period can be calculated based on the number of PDCCH CCEs occupied at each sampling moment in the current first period; and then the PDCCH utilization rate in the current first period is calculated based on the available PDCCHCCE resource capacity of the current cell and the PDCCH CCE resource capacity occupied in the current first period.

or,

The number of available MIMO layers of the current cell in the first period is determined based on the number information of the MIMO layers scheduled by the current cell in the first time period.

Specifically, in a MIMO scenario, it is necessary to determine the number of available MIMO layers of the current cell in the first cycle.

Optionally, the number of available MIMO layers of the current cell in the first period may be determined based on a pre-setting, such as a network management OAM pre-setting, or determined based on a pre-configuration, or pre-defined by a protocol.

Optionally, the number of available MIMO layers of the current cell within the first period can be determined based on relevant information of the MIMO layers scheduled by the current cell within a historical time period (such as the first time period); for example, it can be determined based on the average number of empty layers of CCE of the current cell within the first time period.

In some embodiments, the number of available MIMO layers of the current cell in the first period is determined based on the following method:

When the average user rate weighted based on the user level and the cell flow index weighted based on the service type of the current cell meet the first condition, the number of available MIMO layers of the current cell in the first period is determined based on a preset determination method, a preset constant, a preconfigured determination method, a preconfigured value, a determination method predefined by the protocol, or a value predefined by the protocol;

The third condition includes: the user average rate is greater than the user average rate threshold, and the cell flow index is greater than the cell flow index threshold;

The second condition includes: the user average rate is greater than or equal to the user average rate threshold, and the cell flow index is less than the cell flow index threshold; or, the user average rate is less than the user average rate threshold, and the cell flow index is greater than or equal to the cell flow index threshold; or, the user average rate is equal to the user average rate threshold, and the cell flow index is equal to the cell flow index threshold.

Specifically, the alpha statistical algorithm based on the weighting of cell users and services is shown in formulas (6) to (9):

When the condition UserEx<th_1&DataVol＜th_2 is met, it indicates that the weighted rate of cell users is low and the data traffic of various services generated is low. At this time, the number of available MIMO layers alpha in the first cycle of the current cell is determined by OAM configuration (that is, alpha1), avoiding the additional network overhead caused by dynamic adjustment of alpha.

When the condition UserEx＞th_1&DataVol>th_2 is met, it generally indicates that the weighted rate of users in the cell is high, and the data traffic of various services generated is large. In addition, there are many types of 5G network services, and data bursts occur frequently in a short period of time, resulting in frequent changes in the number of MIMO layers. Therefore, at this time, the number of available MIMO layers in the current cell in the first cycle, alpha, is determined by dynamically calculating the statistical historical cycle data (i.e., alpha3). According to the network resource usage status, the value of alpha is dynamically adjusted to accurately evaluate and plan network resources.

When the values of UserEx and DataVol do not belong to the above two situations, the overall weighted rate of the cell users and the various business traffic generated are at a medium level. At this time, the number of available MIMO layers in the current cell in the first period, alpha, is determined by the maximum value of the average number of MIMO layers in the cell within T2, the median number of MIMO layers, and the mode number of MIMO layers (that is, alpha2). While dynamically adjusting alpha, it does not occupy too much computing resources of the network. T2 is the statistical period of Alpha, which can be a statistical period in the past, such as: the previous week, or the previous month, or the previous three days, or the previous year, or the previous hundred days of the current moment.

Specifically, when determining that the first user and the second user are to be spatially multiplexed based on the aggregation level information of the first user and the aggregation level information of the second user and in combination with the correlation between the first user and the second user, it may be that when the aggregation level of the first user is the same as the aggregation level of the second user and it is determined that the correlation between the first user and the second user is less than a correlation threshold, it is determined that the first user and the second user are to be spatially multiplexed, that is, it is determined that the first PDCCH CCE resource is allocated to the first user and the second user.

In one embodiment, when allocating resources for a first user, the terminal side information of the first user and the network side information of the network to which the first user accesses can be first determined, and then based on the terminal side information of the first user and the network side information of the network to which the first user accesses, the first PDCCH CCE resource that can be allocated to the first user to be allocated resources and the aggregation level information can be determined; and the correlation between the first user and other second users to which resources have been allocated or not allocated can be calculated; and then the first user can be paired with other second users to which resources have been allocated or not allocated, and when the pairing is successful (the aggregation level is the same and the correlation is less than the correlation threshold), the first user and the second user can be considered for spatial division multiplexing, that is, the first user and the second user occupy the same PDCCH CCE resource for scheduling; if the resources of the second user have been allocated, it can be determined that the PDCCH CCE resources occupied by the second user are allocated to the first user; if the resources of the second user have not been allocated, resources that have not been occupied can be allocated to the first user, and when allocating resources to the second user, the PDCCH CCE resources occupied by the first user are allocated.

In some embodiments, determining that the correlation between the first user and the second user is less than a correlation threshold comprises:

Determine a first index value of the strongest beam of the first user;

Determining a second index value of the strongest beam of the second user;

Based on a first reference signal received power (RSRP) of the strongest beam of the first user, a second RSRP of a beam corresponding to a second index value in the beam of the first user, a third RSRP of the strongest beam of the second user, and a fourth RSRP of a beam corresponding to the first index value in the beam of the second user, it is determined that the correlation between the first user and the second user is less than a correlation threshold.

Specifically, when judging whether the correlation between the first user and the second user is less than the correlation threshold, the judgment may be made based on the reference signal received power RSRP of the following beams:

The strongest beam of the first user, the beam corresponding to the second index value among the beams of the first user, the strongest beam of the second user, and the beam corresponding to the first index value among the beams of the second user.

In some embodiments, determining that the correlation between the first user and the second user is less than a correlation threshold based on a first reference signal received power RSRP of the strongest beam of the first user, a second RSRP of a beam corresponding to a second index value in the beam of the first user, a third RSRP of the strongest beam of the second user, and a fourth RSRP of a beam corresponding to the first index value in the beam of the second user, includes:

When the absolute value of the difference between the first RSRP and the second RSRP is greater than a first preset threshold, and the absolute value of the difference between the third RSRP and the fourth RSRP is greater than a second preset threshold, it is determined that the correlation between the first user and the second user is less than a correlation threshold.

Specifically, whether the correlation between the first user and the second user is less than a correlation threshold may be determined based on the following rules:

If RSRP(A, A_max)-RSRP(A, B_max)>the first preset threshold, and RSRP(B, B_max)-RSRP(B, A_max)>the second preset threshold, it is considered that the isolation between the first user's terminal A and the second user's terminal B meets the requirement, where the first preset threshold is a custom threshold value. For the first user's terminal A and the second user's terminal B that meet the isolation requirement, if the first user's terminal A and the second user's terminal B have the same PDCCH candidate position, then the first user's terminal A and the second user's terminal B can send PDCCH in the form of MU-MIMO.

Optionally, the first preset threshold and the second preset threshold may be the same or different. The value of the first preset threshold may be determined based on user needs, or set by the user, or determined based on a protocol predefinition, or obtained based on a preconfiguration; the value of the second preset threshold may be determined based on user needs, or set by the user, or determined based on a protocol predefinition, or obtained based on a preconfiguration.

FIG2 is a schematic diagram of PDCCH space division multiplexing between different user terminals provided by an embodiment of the present application. Taking FIG2 as an example, assuming that there are 32 beam directions in a 64T TDD cell, the strongest beam of the first user's terminal A is assumed to be 18, and the strongest beam of the second user's terminal B is assumed to be 4. If the following two conditions can be met between terminal A and terminal B at the same time: RSRP (A, 18) - RSRP (A, 4) > the first preset threshold, RSRP (B, 4) - RSRP (B, 18) > the second preset threshold, then it can be considered that the beams sent between users have a large degree of isolation. It can be considered that the correlation between the first user and the second user is less than the correlation threshold.

In some embodiments, the method further comprises:

Based on the terminal side information of the first user and the network side information of the network accessed by the first user, it is determined that the first user is in a multi-user scenario.

If the PDCCH spatial resource scheduling function is turned on, the same frequency domain resource problem may occur in the same time slot and the same user on the same beam in a multi-user scenario. Once the PDCCH resource allocation fails, a secondary configuration will be performed until the allocation is successful, which not only increases the scheduling delay, but also consumes additional control information resources. Therefore, the embodiment of the present application uses the mutual difference of the uplink and downlink channels of the TDD system, calculates the correlation between different users in the same cell, and innovatively proposes a downlink control channel resource allocation algorithm for user information, evaluates the feasibility of the PDCCH spatial multiplexing function in a multi-user scenario, and then realizes the improvement of user access delay and connection rate in a multi-user scenario, ensuring the user perception experience in a multi-user scenario.

In one embodiment, when allocating resources for a first user, terminal side information of the first user and network side information of a network accessed by the first user may be first determined, and then based on the terminal side information of the first user and the network side information of the network accessed by the first user, a first PDCCH CCE resource that can be allocated to the first user of the resource to be allocated and aggregation level information may be determined;

If it is determined that the first user is not in a multi-user scenario, the first user can be directly paired with other second users with allocated resources or unallocated resources. When the pairing is successful (the aggregation level is the same), the first user and the second user can be considered for spatial division multiplexing, that is, the first user and the second user occupy the same PDCCH CCE resources for scheduling; if the resources of the second user have been allocated, it can be determined that the PDCCH CCE resources occupied by the second user are allocated to the first user; if the resources of the second user have not been allocated, resources that have not been occupied can be allocated to the first user, and the PDCCH CCE resources occupied by the first user can be allocated when allocating resources to the second user.

If it is determined that the first user is in a multi-user scenario, it is also necessary to calculate the correlation between the first user and other second users to which resources have been allocated or not allocated. The first user can then be paired with other second users to which resources have been allocated or not allocated. When the pairing is successful (the aggregation level is the same and the correlation is less than the correlation threshold), the first user and the second user can be considered for spatial division multiplexing, that is, the first user and the second user occupy the same PDCCH CCE resources for scheduling. If the resources of the second user have been allocated, it can be determined that the PDCCH CCE resources occupied by the second user are allocated to the first user. If the resources of the second user have not been allocated, the resources that have not been occupied can be allocated to the first user, and the PDCCH CCE resources occupied by the first user can be allocated when allocating resources to the second user.
