Description

Technical Field

[0001] The present invention relates to the field of communication technologies, and particularly to a method, apparatus, and network device for determining a scheduling terminal. Background Art

[0002] In a fifth-generation mobile communication high-frequency band (millimeter-wave) transmission network, there are multiple transmission beams on the base station side for downlink, and one or more beams can be transmitted at the same time. In the case where the Physical Downlink Control Channel (PDCCH) needs to send scheduling authorizations for the Physical Downlink Shared Channel (PDSCH) and the Physical Uplink Shared Channel (PUSCH) in the same time slot, the PDCCH beam is restricted by the transmission beam, so that the corresponding PDSCH and PUSCH users need to be for the user equipment (UE) in the beam direction. At this time, it is necessary to determine the beam direction based on the priorities of the uplink and downlink users to be scheduled, and further determine the time-domain priority order of the uplink and downlink.

[0003] However, this method in the prior art may increase the delay. For example:

[0004] a) Based on the queuing of downlink users to be scheduled, the selected high-priority user is UE2;

[0005] b) If the beam direction corresponding to UE2 is beamA, then the authorized PDCCH beam needs to be in this beam direction;

[0006] c) When scheduling users in the uplink time slot corresponding to the authorized PDCCH, it is also necessary to schedule the UE in the BeamA direction.

[0007] But at this time, the highest-priority user in the uplink is UE5, and the beam direction is BeamB. Then UE5 cannot be scheduled, and the delay of UE5 increases, and the performance experience of high-priority users cannot be guaranteed. Summary of the Invention

Rather, the use of words such as "exemplary" or "for example" is intended to present relevant concepts in a specific manner.

[0079] The embodiments of this application are introduced below in conjunction with the accompanying drawings. The scheduling terminal determination method, device and network device provided by the embodiments of this application can be applied to a wireless communication system. The wireless communication system can be a system adopting the fifth-generation (5G) mobile communication technology (hereinafter simply referred to as the 5G system). Those skilled in the art can understand that the 5G NR system is only an example and not a limitation.

[0080] See Figure 1 , Figure 1 is a structural diagram of a network system to which the embodiments of this application can be applied. As Figure 1As shown in the figure, it includes a user terminal 11 and a base station 12. Among them, the user terminal 11 can be a user equipment (UE). For example, it can be a mobile phone, a tablet personal computer, a laptop computer, a personal digital assistant (PDA), a mobile Internet device (MID), or a wearable device, etc. terminal-side devices. It should be noted that in the embodiments of this application, the specific type of the user terminal 11 is not limited. The above base station 12 can be a base station of 5G and later versions (for example: gNB, 5G NR NB), or a base station in other communication systems, or called Node B. It should be noted that in the embodiments of this application, only a 5G base station is taken as an example, but the specific type of the base station 12 is not limited.

[0081] Among them, the method and the device are based on the same inventive concept. Since the principles of the method and the device for solving problems are similar, the implementation of the device and the method can be referred to each other, and the repeated parts will not be described again.

[0082] As Figure 2 shown, an embodiment of the present invention provides a method for determining a scheduling terminal, which is executed by a network device and includes:

[0083] Step S201, obtain the uplink and / or downlink scheduling data information corresponding to the physical downlink control channel PDCCH authorization of the target processing time slot;

[0084] It should be noted that the target processing time slot refers to the time slot that the network device is processing. Since the network device processes time slots one by one, that is to say, when processing the current time slot, the current time slot is called the target processing time slot.

[0085] Step S202, perform comprehensive time-domain priority sorting for the uplink and downlink according to the uplink and / or downlink scheduling data information;

[0086] Step S203, determine the beam direction of the PDCCH authorization according to the sorting result of the comprehensive time-domain priority sorting of the uplink and downlink;

[0087] Step S204, determine the terminal to be scheduled according to the beam direction.

[0088] It should be noted that in the embodiments of the present application, by performing comprehensive time-domain priority sorting for the uplink and downlink based on the to-be-scheduled data information corresponding to the uplink and / or downlink respectively, determining the beam direction of the PDCCH authorization according to the sorting result of the comprehensive time-domain priority sorting for the uplink and downlink, and then determining the to-be-scheduled terminal according to the beam direction; this method of determining the to-be-scheduled terminal can ensure the transmission performance of high-priority services and reduce the transmission delay of high-priority services.

[0089] Optionally, the implementation method that can be adopted in step S201 of the embodiments of the present application is as follows:

[0090] Step S2011, determine the time slot lists corresponding to the downlink and uplink respectively that need to be sent by the PDCCH in the target processing time slot;

[0091] It should be noted that in this step, a downlink time slot list and an uplink time slot list are obtained respectively. For example, optionally, the downlink time slot list can be expressed as dlslot_list = {dlslot1, ……, dlslot Ndl}, where Ndl is the number of downlink time slots that need to be sent by the PDCCH in the target processing time slot, dlslot i is the downlink time slot number, and i = 1, 2, … Ndl. The uplink time slot list can be expressed as ulslot_list = {ulslot1, ……, ulslot Mul}, where Mul is the number of uplink time slots that need to be sent by the PDCCH in the target processing time slot, ulslot j is the uplink time slot number, and j = 1, 2, … Mul.

[0092] Step S2012, when the list corresponding to the target element is not empty, determine the to-be-scheduled data information corresponding to the target element;

[0093] Wherein, the target element includes: the uplink and / or the downlink.

[0094] That is to say, after obtaining the time slot lists corresponding to the downlink and uplink respectively, it is necessary to determine whether there are elements corresponding to both in the downlink time slot list and the uplink time slot list (that is, to determine whether there are time slot numbers in the downlink time slot list and the uplink time slot list). When the downlink time slot list is not empty, obtain the to-be-scheduled data information corresponding to each element in the downlink time slot list respectively; when the uplink time slot list is not empty, obtain the to-be-scheduled data information corresponding to each element in the uplink time slot list respectively.

[0095] Optionally, the to-be-scheduled data information includes:

[0096] The to-be-scheduled terminal list, the PDCCH beam direction corresponding to each to-be-scheduled terminal respectively, and the priority hierarchical data to which the to-be-scheduled terminal belongs.

[0097] Optionally, if the elements in the downlink time slot list dlslot_list are not empty, obtain the downlink terminal list to be scheduled. For example, if the downlink time slot list includes two time slots, the first time slot corresponds to a downlink terminal list to be scheduled, and the second time slot also corresponds to a downlink terminal list to be scheduled.

[0098] The downlink terminal list to be scheduled can be expressed as:

[0099] dlslot_ue_list = {dlslot_ue1, dlslot_ue2, ……, dlslot_ue Idl};

[0100] where, Idl is the number of downlink time slot terminals to be scheduled, and dlslot_ue m is the downlink terminal to be scheduled, and m = 1, 2, … Idl.

[0101] The PDCCH beam directions corresponding to the downlink terminals to be scheduled can be expressed as:

[0102] dl_uebeam_list = {dlslot_uebeam1, dlslot_uebeam2, ……, dlslot_uebeam Idl};

[0103] where, dlslot_uebeam m is the PDCCH beam direction corresponding to the m-th terminal to be scheduled.

[0104] The priority hierarchical data to which the downlink terminals to be scheduled belong can be expressed as:

[0105] dlslot_uelayerIndex_list = {dlslot_uelayerIndex1, dlslot_uelayerIndex2, ……, dlslot_uelayerIndex Idl};

[0106] where, dlslot_uelayerIndex m is the priority hierarchy to which the m-th terminal to be scheduled belongs.

[0107] It should be noted that the priority hierarchy to which the downlink terminals to be scheduled belong is preset. That is to say, which priority hierarchy the terminal belongs to can be pre-configured, protocol-agreed or configured by a higher layer.

[0108] It should be noted here that dlslot_ue_list, dl_uebeam_list, and dlslot_uelayerIndex_list all correspond to one downlink time slot, which can be referred to as a set of downlink data to be scheduled. That is to say, if there are several downlink time slots in the downlink time slot list, there will be several sets of downlink data to be scheduled.

[0109] Optionally, if the elements in the uplink time slot list ulslot_list are not empty, obtain the uplink terminal list to be scheduled. For example, if the uplink time slot list includes two time slots, then the first time slot corresponds to an uplink terminal list to be scheduled, and the second time slot also corresponds to an uplink terminal list to be scheduled.

[0110] The uplink terminal list to be scheduled can be expressed as:

[0111] ulslot_ue_list = {ulslot_ue1, ulslot_ue2, ……, ulslot_ue Jul};

[0112] where Jul is the number of uplink terminals to be scheduled in one uplink time slot, and ulslot_ue n is the uplink terminal to be scheduled, and n = 1, 2, … Jul.

[0113] The PDCCH beam directions corresponding to the uplink terminals to be scheduled can be expressed as:

[0114] ul_uebeam_list = {ulslot_uebeam1, ulslot_uebeam2, ……, ulslot_uebeam Jul};

[0115] where ulslot_uebeam n is the PDCCH beam direction corresponding to the nth terminal to be scheduled.

[0116] The priority hierarchical data to which the uplink terminals to be scheduled belong can be expressed as:

[0117] ulslot_uelayerIndex_list = {ulslot_uelayerIndex1, ulslot_uelayerIndex2, ……, ulslot_uelayerIndex Jul};

[0118] where ulslot_uelayerIndex n is the priority hierarchy to which the nth terminal to be scheduled belongs.

[0119] It should be noted that the priority stratification to which the uplink terminals to be scheduled belong is pre-set. That is to say, which priority stratification a terminal belongs to can be pre-configured, protocol-agreed, or configured by a higher layer.

[0120] It should be noted here that ulslot_ue_list, ul_uebeam_list, and ulslot_uelayerIndex_list all correspond to one uplink time slot, which can be called a set of uplink data information to be scheduled. That is to say, if there are several uplink time slots in the uplink time slot list, there will be several sets of uplink data information to be scheduled.

[0121] It should be noted that for the above-mentioned downlink terminals to be scheduled list and uplink terminals to be scheduled list, the embodiments of the present application do not limit the sorting order of the terminals in the list. For example, the terminals can be sorted by means of round-robin polling, proportional fairness, etc.

[0122] It should be noted that after obtaining the data information to be scheduled, the comprehensive time-domain priority sorting of the uplink and downlink is performed. The specific implementation process is as follows:

[0123] Step S2021, obtain the uplink and downlink hierarchical comprehensive priority table;

[0124] It should be noted that the uplink and downlink hierarchical comprehensive priority table is pre-set, and it is set based on the service priorities of the uplink and downlink and in accordance with the rule of sorting from high to low according to the priority stratification.

[0125] For example, the uplink and downlink hierarchical comprehensive priority table is set to a total of P layers, that is, layerIndex_list = {1, 2, ……, P}, and the priority of the priority stratification ranked in the front in the table is higher than that of the priority stratification ranked in the back.

[0126] The downlink layer priority index corresponding to each priority stratification in the uplink and downlink hierarchical comprehensive priority table is:

[0127] dlLayerIndex_inALL_list = {dlLayerIndex1, dlLayerIndex2, ……, dlLayerIndex P}

[0128] The uplink layer priority index corresponding to each priority stratification in the uplink and downlink hierarchical comprehensive priority table is:

[0129] ulLayerIndex_inALL_list = {ulLayerIndex1, ulLayerIndex2, ……, ulLayerIndex P}

[0130] wherein, dlLayerIndex i or ulLayerIndex i can be a NULL value, which means that this layer does not correspond to the downlink priority layer or the uplink priority layer.

[0131] For example, the combined uplink and downlink hierarchical priority table can be seen in Table 1 as follows:

[0132] Table 1 Schematic Diagram of the Combined Uplink and Downlink Hierarchical Priority Table

[0133]

[0134] Step S2022, perform combined time-domain priority sorting for uplink and downlink according to the combined uplink and downlink hierarchical priority table and the data information to be scheduled corresponding to the uplink and / or downlink respectively;

[0135] It should be noted that in this step, combined time-domain priority sorting for uplink and downlink is performed according to the combined uplink and downlink hierarchical priority table and the obtained data information to be scheduled. The specific implementation process can be:

[0136] Select the first terminals to be scheduled in the list of terminals to be scheduled in the data information to be scheduled corresponding to the uplink and / or downlink respectively, whose hierarchical indexes in the combined uplink and downlink hierarchical priority table are the same;

[0137] Perform time-domain priority sorting for the first terminals to be scheduled according to the inter-layer priority order in the combined uplink and downlink hierarchical priority table.

[0138] For example, find the layerIndex value in layerIndex_list where the uplink priority layer index in the data of ulslot_uelayerIndex_list is located:

[0139] ulslot_uelayerIndex_list = {uelayerIndex UL1 , uelayerIndex UL2 , ……, uelayerIndex ULJul}.

[0140] Find the layerIndex value in layerIndex_list where the uplink layer index in the data of dlslot_uelayerIndex_list is located:

[0141] dlslot_uelayerIndex_list = {uelayerIndex DL1, uelayerIndex DL2 , ……, uelayerIndex DLIdl}。

[0142] Then, the scheduled terminals in the downlink scheduled data and the uplink scheduled data with the same layerIndex in the corresponding uplink and downlink hierarchical comprehensive priority table are placed in a queue, as shown in Table 2. The layerIndex p The corresponding scheduled terminal is UEList p , which includes uplink scheduled terminals and downlink scheduled terminals.

[0143] Table 2 layerIndex p Corresponding relationship table with the scheduled terminal

[0144]

[0145] Perform time-domain priority sorting on the first scheduled terminal according to the inter-layer priority order of the uplink and downlink hierarchical comprehensive priority table, that is, arrange the scheduled terminals in Table 2 in the order of layerIndex_list, and the final sorted list is:

[0146] Optionally, after obtaining the sorting result by performing comprehensive time-domain priority sorting on the uplink and downlink, the beam direction of the PDCCH authorization is determined according to the sorting result. The specific implementation method can be as follows:

[0147] According to the number of beam directions corresponding to the PDCCH authorization, determine the PDCCH beam directions corresponding to the scheduled terminals ranked in the top N in the sorting result as the beam directions of the PDCCH authorization;

[0148] where N is the number of beam directions corresponding to the PDCCH authorization.

[0149] That is to say, if the PDCCH authorizes several beam directions, then determine the several beam directions with the highest priority.

[0150] Furthermore, it should be noted that after selecting the beam direction of the PDCCH authorization, the scheduled moments corresponding to the time slot lists corresponding to the downlink and uplink respectively can be used to screen out the uplink and downlink scheduled terminals in the scheduled data information according to the beam direction.

[0151] Further, it should be noted that after obtaining the uplink and downlink terminals to be scheduled, the network device can also sort the uplink terminals to be scheduled according to the uplink hierarchical priority and the in-layer priority order; and sort the downlink terminals to be scheduled according to the downlink hierarchical priority and the in-layer priority order.

[0152] The following is a specific application example of this application, which is described as follows.

[0153] Specific application case 1

[0154] The main processes in this case include:

[0155] 1. First, determine the downlink time slot list and uplink time slot list for which the PDCCH needs to send authorization in the current processing time slot:

Based on the first terminals to be scheduled in the list of terminals to be scheduled in the data information to be scheduled, for which the hierarchical indexes in the up and downlink hierarchical comprehensive priority table are consistent, obtain a sorted list according to the hierarchical indexes.

If there are both uplink and downlink data elements to be scheduled in the uplink and downlink hierarchical comprehensive priority table, their priorities are comprehensively considered, and finally the beam direction corresponding to the UE with the highest time-domain priority is selected; further participate in the time-domain priority sorting of the corresponding uplink and downlink slots, which ensures the service performance with higher uplink and downlink priorities.
