technical field

The embodiment of the present application relates to the field of communications, and in particular to a method, server and storage medium for allocating PDCCH resources.

Background technique

In 5G, the downlink control channel (Physical Downlink Control Channel, PDCCH) is responsible for the transmission of various key control information at the physical layer. The downlink control information (Downlink Control Information, DCI) transmitted in the PDCCH can include: downlink scheduling information, uplink scheduling Information, activation and deactivation of Physical Uplink Shared Channel (Physical Uplink Shared Channel, PUSCH) scheduling, activation and deactivation of Physical Downlink Shared Channel (Physical Downlink Shared Channel, PDSCH) semi-persistent scheduling, etc. That is, the user equipment (User Equipment, UE) can specify the format and scheduling of the traffic channel according to the downlink control information (Downlink Control Information, DCI), and send or receive data accordingly.

The set of time-frequency resources that can be used by PDCCH is called Control Resource Set (CORESET), and the control channel element (Control Channel Element, CCE) is used as the basic resource unit in CORESET. A CCE is composed of 6 Resource Element Groups (Resource Element Group, REG), and a REG is composed of one symbol in the time domain and 12 consecutive subcarriers in the frequency domain. The PDCCH can include 1, 2, 4, 8, and 16 CCE aggregations, and different numbers of CCEs represent different aggregation levels (Aggregation Level, AL). The higher the aggregation level, the more time-frequency resources can be used, and the higher the probability that DCI can be received correctly. The position of the PDCCH in the control resource set is not set arbitrarily. According to the 3GPP agreement, in the whole set of control resources, under different aggregation levels, the number of candidate positions that can be used by the PDDCH is fixed, and the specific positions of the candidate sets are fixed. All candidate PDCCH positions constitute a search space.

With the development of wireless communication technology, the number of users who need to be scheduled in the same cell at the same time will increase. Especially in the case of small bandwidth, PDCCH resources will become more tense, which will affect services such as PDSCH and affect users. Transmission of terminal business traffic.

However, those of ordinary skill in the art can understand that in each embodiment of the application, many technical details are provided for readers to better understand the application. However, even without these technical details and various changes and modifications based on the following embodiments, the technical solutions claimed in this application can also be realized. The division of the following embodiments is for the convenience of description, and should not constitute any limitation to the specific implementation of the present application, and the embodiments can be combined and referred to each other on the premise of no contradiction.

The main purpose of the embodiments of the present application is to propose a PDCCH resource allocation method, server, and storage medium, which can improve the success rate of PDCCH resource allocation and improve spectrum efficiency, so as to alleviate the impact of insufficient PDCCH resources in the multi-user scenario of the cell. The purpose of user business data transmission.

The method for allocating PDCCH resources in this embodiment can be applied to electronic devices such as base stations. The resource allocation method in this embodiment includes: obtaining each resource position corresponding to the aggregation degree of the user equipment UE to which resources are to be allocated; judging whether there is a resource position that meets the space division requirement among the resource positions; the space division requirement includes: There is an idle space layer on the resource location and the number of CCEs of the idle space layer matches the aggregation degree of the UE, and the attribute characteristics of the space-divided UE on the resource location match the attribute characteristics of the UE , the available power at the resource position matches the power required by all UEs in the empty group where the UE is located; if there is a resource position that meets the space division requirement, the The idle space layer is allocated to the UE.

In the embodiment of the present application, resources are first allocated to the terminal by frequency division. When the frequency division allocation fails, it is judged whether there is a resource position that meets the space division requirements in each resource position, and the space resource is fully utilized, which can improve the success rate of PDCCH allocation, that is, Improve the utilization rate of PDCCH resources and improve spectrum efficiency, so as to alleviate the impact of insufficient PDCCH resources on user services in the multi-user scenario of the cell.

In this embodiment, it is judged whether there is a resource location that meets the space division requirement in each resource location, and making full use of space resources can improve the success rate of PDCCH resource allocation and improve spectrum efficiency, so as to alleviate the problem of PDCCH resource allocation in a multi-user scenario in a cell. Not enough to affect the purpose of user business data transmission.

The implementation details of the method for allocating PDCCH resources in this embodiment will be described in detail below. The following content is only implementation details provided for easy understanding, and is not necessary for implementing this solution.

The flow of the PDCCH resource allocation method in this embodiment may be shown in Figure 1, including:

Step 101 , acquiring resource positions corresponding to aggregation degrees of user equipment UE to which resources are to be allocated.

In some embodiments, in the resource search space corresponding to the aggregation degree of the UE, multiple control resource sets CORESET are searched; multiple resource positions in each CORESET are obtained.

Exemplarily, the base station sequentially selects UEs from the queue of UEs to be scheduled, and the current UE is the i-th UE, obtains the aggregation degree of the i-th UE, obtains a dedicated search space corresponding to the aggregation degree of the i-th UE, and obtains the corresponding Candidate positions are obtained from the set of control resources, that is, the resource positions corresponding to the degree of aggregation.

Step 102, allocate PDCCH resources to the terminal by means of frequency division. Specifically, based on each resource position corresponding to the aggregation degree of the UE, resources are allocated to the UE in a frequency division manner.

In some embodiments, it is detected whether there is a resource position that meets the frequency division requirement in each resource position, that is, it is detected whether the number of CCEs on each resource position matches the aggregation degree of the UE, and the available power on the resource position is consistent with the Whether the power required by the above-mentioned UE matches, and if both match, allocate the resource corresponding to the resource position to the terminal.

Exemplarily, it is detected whether the number of CCEs in each resource location matches the aggregation degree of the UE, and the available power on a single symbol is sufficient for allocation to the i-th UE, and the total available power of uplink/downlink is sufficient for allocation to the i-th UE, If the above conditions are not met, resource allocation fails according to the current UE aggregation degree and power.

If the above conditions are met, determine whether the number of downlink CCEs matches the aggregation degree of the i-th UE, and the physical resource block (Physical Resource Block, PRB) allocated to the candidate position by the i-th UE is not occupied. The allocation method is that the PDCCH resources are allocated to the terminal successfully, and the corresponding position of the REG level bitmap at the cell level is set as frequency division unavailable.

In some embodiments, if there is no match, that is, there is no resource position satisfying the frequency division requirement among the resource positions, it is determined that resource allocation by the frequency division method fails, and step 103 is performed.

Step 103, when resource allocation for the UE by frequency division fails, determine whether there is a resource position satisfying the space division requirement among the resource positions.

In this embodiment, the space division requirement may include: there is an idle space layer on the resource location, and the number of PRBs with the idle space layer matches the aggregation degree of the UE, and the PRBs within the range of the base station The attribute characteristics of the space-divided UE match the attribute characteristics of the UE, and the available power of the base station matches the power required by all UEs in the empty group where the UE is located.

In some embodiments, the current space layer number of each resource block on the resource location is identified, and the largest current space layer number among the current space layer numbers of each PRB is used as the current space layer number of the resource location The number of layers; if the current number of empty layers in the resource location is less than the preset number of empty layers threshold, it is determined that there is an idle layer in the resource location. Idle layers are determined in this way, and if the current number of empty layers does not reach the maximum threshold, it indicates that there is room for expansion of the empty layers.

In some embodiments, the attribute feature of the space-divided UE within the range of the base station matches the attribute feature of the UE, which may include: the resource configuration type of the space-divided UE at the resource location is the same as the resource configuration type of the UE , the spatial positions of all space-divided UEs within the range of the base station are correlated with the spatial positions of the UEs.

The resource configuration type may include: REG Bundle Size of the UE and the absolute position of the occupied RB. Among them, REG Bundle is a bundling unit composed of several consecutive REGs in the frequency domain or time domain in CORESET, and is the smallest unit of CCE-to-REG interleaved mapping. The number of REGs in the REG Bundle is REG Bundle Size.

In some embodiments, the available power of the base station matches the power required by all UEs in the empty group where the UE is located, which may include: the available power on a single symbol meets the power increase of all UEs in the empty group where the UE is located Allocation requirements, and the total available uplink/downlink power of the base station meets the allocation requirements of the power increase required by all UEs in the empty group where the UE is located.

Exemplarily, the number of empty layers of each candidate position is calculated, that is, the number of empty layers of each resource position is calculated, and the maximum number of empty layers in the PRB corresponding to the candidate position is taken as the maximum number of empty layers of the candidate position, and Each candidate position is sorted in the order of arrival from the smallest number of empty layers, and the candidate position set M_can is obtained, and the candidate position set M_can is traversed, and each empty layer of the current candidate position is traversed until the first candidate position with an available PRB position is found. , and use the spatial position of the empty layer as the resource position of the current terminal.

If the resource location of the current UE is found, determine whether the resource location of the current UE is the same as the resource location of the resource location in the same frequency domain as the resource configuration type of the space-divided UE, that is, whether the REG Bundle Size of the UE and the absolute location of the occupied RB are the same, If not, continue the traversal of M_can.

If the resource configuration type of the space-divided UE at the resource location is the same as the resource configuration type of the UE, then calculate the correlation before and after the null trap of the covariance matrix according to the weights of the current UE and the space-divided UE within the range of the base station, and judge Whether the correlation is greater than a certain threshold PDCCHcorr_THR, if the correlation is greater than a certain threshold PDCCHcorr_THR, it means that the attribute feature of the space-divided UE within the range of the base station matches the attribute feature of the UE.

If the attributes and characteristics match, the power of the terminal is corrected without changing the aggregation degree, that is, the power of all UEs in the empty group is increased based on the correlation loss amount, and the power of the space-divided UE is corrected. Detect that the available power on a single symbol is sufficient for all UE power increase allocations of the empty group and the total available power of the base station's uplink/downlink is sufficient for the empty group power increase allocation, if yes, the user equipment's space layer number id number It is assumed that the candidate position has the id number of the empty layer of the available PRB position, and the id number of the empty layer of each PRB position is updated with the actual number of empty layers of each position. If the above power conditions are also satisfied, it indicates that there is a resource location that meets the space division requirement.

Step 104, if there is a resource position satisfying the space division requirement, allocate the resource position satisfying the space division requirement to the UE. Specifically, the UE is also specified to use the idle space layer at the resource location.

In this embodiment, judging whether there is a resource location that meets the space division requirements in each resource location, making full use of the space resource, can improve the allocation success rate of the PDCCH resource, and improve the spectrum efficiency, so as to alleviate the problem caused by PDCCH resources in the multi-user scenario of the cell. Not enough to affect the purpose of user business data transmission.

Another embodiment of the present application relates to a method for PDCCH resource allocation. The implementation details of PDCCH resource allocation in this embodiment are described below in detail. The following content is only the implementation details provided for easy understanding, and is not necessary for implementing this solution. Fig. 2 is a flow chart of the method for PDCCH resource allocation described in this embodiment, the method includes:

Step 201 , acquiring resource positions corresponding to aggregation degrees of user equipment UEs to which resources are to be allocated.

Step 201 is substantially the same as the above-mentioned step 101, and will not be repeated here.

In some embodiments, after acquiring the resource positions corresponding to the aggregation degrees of the user equipment UE to which resources are to be allocated, the resource positions are stored in the storage unit. In this embodiment, when each resource location needs to be used subsequently, such as frequency-division allocated resources or space-divided allocated resources, it can be directly read from the storage unit without reacquiring each resource location.

Step 202, allocate PDCCH resources to the terminal in a frequency division manner. The terminal is the user equipment UE. Step 202 is roughly the same as step 201, except that: in some other embodiments, if there is no resource position that meets the frequency division requirement in each resource position, then update the UE's aggregation degree and the UE's required Power, and judge again whether there is a resource location that meets the frequency division requirement among the resource locations, and when it is determined again that there is no resource location that meets the frequency division requirement among the resource locations, go to step 203. In this embodiment, the updated UE aggregation degree and UE required power may be referred to as secondary aggregation degree and secondary power, and the UE aggregation degree and UE required power before updating may be referred to as secondary aggregation degree and secondary power. In this embodiment, the second-choice aggregation degree and the second-choice power are selected for frequency division, and the complexity of frequency division is relatively low. Therefore, the complexity of resource allocation can be reduced as much as possible by allocating resources through frequency division.

In some embodiments, after the aggregation degree of the UE and the power required by the UE are updated, the updated aggregation degree of the UE and the power required by the UE are stored in a storage unit. This embodiment facilitates the subsequent acquisition of parameters such as the aggregation degree of the UE and the power required by the UE directly from the storage unit.

Step 203, if resource allocation by frequency division method fails, determine whether the UE is allowed to allocate space domain resources.

In some embodiments, if the number of CCEs at the resource location does not match the aggregation degree of the UE, or the available power at the resource location does not match the power required by the UE, allocate resources by frequency division fail.

In some embodiments, judging whether the UE is allowed to allocate space domain resources may include: judging whether the base station is allowed to communicate with the UE based on space division technology, whether the UE supports space division technology, and whether the connection between the UE and the base station is normal .

When the UE configuration does not support space division, the corresponding position of the REG level bitmap at the cell level can be set to be not used for space division.

When the base station allows communication with the UE based on space separation technology, the UE supports space separation technology, and the connection between the UE and the base station is normal, it means that it is determined that the UE is allowed to allocate space domain resources, and the steps can be performed 204.

Exemplarily, judging whether the UE is allowed to allocate space domain resources needs to meet the following conditions: first, the network management configures the PDCCH MU switch to be turned on; second, the CCE power utilization rate of the cell is less than a certain preset threshold CCEPower_thr, wherein the value range of CCEPower_thr is [0 ,1]; Third, the CCE allocation failure rate of the cell is greater than or equal to a certain preset threshold CCEFail_thr, where the value range of CCEFail_thr is [0,1].

Exemplarily, if the UE is a potential space division UE, that is, the UE supports space division technology, the following conditions need to be met: the transmission mode of the UE is a precoding matrix indicator (Precoding Matrix Indicator, PMI), and the adaptive coding and modulation signal of the UE and The interference plus noise ratio (Adaptive Modulation and Coding Signal to Interference plus Noise Ratio, AMC SINR) is greater than the preset threshold value; the UE is a PDCCH in a dedicated CORESET.

If the transmission mode of the user equipment is non-PMI mode, it is classified as a "frequency division user", and if the AMC SINR of the user equipment does not meet the threshold, the user is classified as a "frequency division user". PDCCH, the user equipment is classified as a "frequency division user", and if the user equipment is a "frequency division user", resources are not allocated through space division.

Step 204: If the UE is allowed to allocate space domain resources, it is judged whether there is a resource position satisfying the space division requirement among the resource positions.

In some embodiments, if there is no resource position satisfying the space division condition, the updated aggregation degree of the UE and the power required by the UE are acquired from the storage unit, and the resources are judged again Whether there is a resource location that meets the space division requirement in the location, and after judging that there is a resource location that meets the space division requirement, allocate the idle space layer on the resource location that meets the space division requirement to the UE . In this embodiment, the space division method is used to allocate resources. When the primary aggregation degree and primary power space division fails, the secondary aggregation degree and secondary power stored during the frequency division allocation can be used, and the space division is tried again to further reduce the resources due to resource allocation. Failure, resulting in a situation that affects the terminal's transmission traffic.

In some embodiments, if the sub-aggregation degree and sub-power allocation of the root terminal fail, it can be tried whether it can be allocated in CORESET0, that is, according to CORESET0, reacquire the resource positions corresponding to the aggregation degree of the user equipment UE to be allocated resources.

In addition, the allocation principles of air separation resources are as follows:

1. Since the minimum granularity of weight calculation is the REG Bundle level, it is necessary to follow the principle of REG Bundle not bridging before it can be space separated, that is, a REG Bundle of the same UE cannot be space separated with two frequency division UEs;

2. In the conservative state, only the CCE space division of the same CORESET is allowed. The REG Bundle Size and interleaving method of the same CORESET are the same, which are controlled by the parameter control set -> bundle unit specification (ControlResourceSet->reg-BundleSize) and the parameter control set -> cce-REG mapping type (ControlResourceSet->cce-REG-MappingType) configuration, so there will be no misplacement after mapping to REG.

3. If the CCE space division of different CORESETs, the REG Bundle Size and the interleaving method are not necessarily the same, there may be misalignment in the mapping to the REG.

Figure 3 is the REG Bundle space separation scene with good bits. In Figure 3, 301 means good bits. The REG Bundle Size is the same, but the number of symbols is different. In Figure 3, 302 means good bits. The REG Bundle Size is different, and the number of symbols is different; in Figure 3, 303 means Not bad, the REG Bundle Size is different, and the number of symbols is the same.

Figure 4 is the REG Bundle dislocation space separation scene. In Figure 4, 401 represents dislocation, REG Bundle Size is the same, and the number of symbols is the same. In Figure 4, 402 represents dislocation, REG Bundle Size is the same, but the number of symbols is different. In Figure 4, 403 represents dislocation, and REG The Bundle Size is different, and the number of symbols is different. In Figure 4, 404 represents dislocation, and the REG Bundle Size is different, but the number of symbols is the same.

4. When assigning UE space division positions, it is necessary to maintain an RB index table of Nrb*Mlayer, which is initialized to all 0s. When the UE RB position allocation is successful, the corresponding RB index table position is set to 1. For non-aligned space division That is, it is also necessary to set the index positions of all non-spaced RBs in the REG Bundle where the corresponding spaced RB is located to invalid (invalid).

Step 205, if there is a resource position satisfying the space division requirement, allocate the resource position satisfying the space division requirement to the UE.

In step 204 of this embodiment, judging whether there is a resource location meeting the space division requirement in each resource location is roughly the same as the above-mentioned 103, and step 205 is roughly the same as the above-mentioned 104, and this embodiment will not repeat them.

In this embodiment, when the frequency division fails, the frequency division is performed again through the secondary aggregation degree and the secondary power, so that the complexity of resource allocation can be reduced as much as possible. In addition, when the space division fails, the secondary aggregation degree and the secondary power are used. Carrying out space division again can maximize the success rate of PDCCH resource allocation and improve spectrum efficiency, so as to achieve the purpose of alleviating the impact of insufficient PDCCH resources on user service data transmission in the multi-user scenario of the cell.
