Detailed Description
The embodiment of the invention can be applied to 2G, 3G and 4G systems, or 5G systems, or new systems generated in the future. The 4G system may be a Long Term Evolution (LTE) system, and the 5G system may be a New Radio (NR) system.
Fig. 1 illustrates an architecture of a communication system including a network device and a user device.
User Equipment (UE), also called Terminal Equipment, Terminal, Mobile Station (MS), Mobile Terminal (MT), etc., is a device that provides voice and/or data connectivity to a User, for example, a handheld device, a vehicle-mounted device, etc. with a wireless connection function. Currently, some examples of terminals are: a Mobile phone (Mobile phone), a tablet computer, a notebook computer, a palm computer, a Mobile Internet Device (MID), a wearable Device, a Virtual Reality (VR) Device, an Augmented Reality (AR) Device, a wireless terminal in Industrial Control (Industrial Control), a wireless terminal in unmanned driving (self driving), a wireless terminal in remote surgery (remote medical supply), a wireless terminal in smart grid (smart grid), a wireless terminal in transportation safety, a wireless terminal in city (smart city), a wireless terminal in smart home (smart home), and the like.
The network device related in the embodiment of the present invention may be AN Access network device, and the Access network device may also be referred to as a base station or AN Access Node (Access Node, abbreviated as AN) to provide a wireless Access service for a terminal. The Access Node may be a Base Transceiver Station (BTS) in a Global System for Mobile communication (GSM) System or a Code Division Multiple Access (CDMA) System, a Base Station (NodeB) in a Wideband Code Division Multiple Access (WCDMA) System, an evolved Node B (eNB or eNodeB) in an LTE System, or a Base Station device (gbb), a small Base Station device, a wireless Access Node (WiFi AP), a wireless interworking Microwave Access Base Station (WiMAX BS) in a future 5G network, which is not limited in this respect.
The plurality of the present invention means two or more. "and/or" describes the association relationship of the associated objects, meaning that there may be three relationships, e.g., a and/or B, which may mean: a exists alone, A and B exist simultaneously, and B exists alone. The character "/" generally indicates that the former and latter associated objects are in an "or" relationship. In addition, it should be understood that although the terms first, second, etc. may be used to describe various objects (such as uplink interference level, uplink received interference power, etc.) in the embodiments of the present invention, these data packets should not be limited by these terms. These terms are only used to distinguish objects from each other.
SR is one way for a UE to apply resources to a network device for new data transmission. The SR belongs to information of a physical layer, and the UE transmits the SR without radio bearer resources, and may transmit the SR through a Physical Uplink Control Channel (PUCCH). If the connected UE has a data transmission requirement, but does not have uplink authorization and has SR resources, the SR is transmitted first to request to allocate a small amount of resources. After the network device successfully decodes an SR signal of a certain UE, it may allocate a certain PRB resource to the UE through a Downlink Control Information (DCI), where the PRB resource is generally obtained through calculation of a default data amount and a channel condition of a base station.
The 4G network not only provides high-rate data services, but also provides high-quality audio and video calls. The specification of the number of users in the network is increasing and the types of services are more and more diversified, in order to meet the requirements of users for establishing different quality of service (QoS) bearers as much as possible, the queues of users to be scheduled maintained at the network equipment side and the priorities among the queues are as shown in fig. 2, wherein arrows mark that the priorities among different scheduling queues are sequentially reduced from left to right. The priorities among the scheduling queues are sequentially from big to small retransmission users- > the user who sends Msg 3- > the user who sends Logical Channel Group (LCG)0 has the cache data volume larger than 0- > the user who sends SR- > the user who has LCG1 has the cache data volume larger than 0- > the user who has LCG2 has the cache data volume larger than 0- > the user who has LCG3 has the cache data volume larger than 0- > other users.
Here, 1) and the retransmission user mean a user who needs to retransmit data.
2) Msg3 is used to transmit information related to a Radio Resource Control (RRC) layer. The Msg3 message may include Information such as rrcConnectionRequest (RRC connection request), rrcconnectionreconfigurationcomplete (RRC connection configuration complete), rrcconnectionrequestablistensionrequest (RRC reestablishment connection request), and UL Information Transfer (uplink Information Transfer).
3) And a logical channel group. In order to reduce uplink channel overhead, generally, UE uplink logical channels LC are divided into logical channel groups LCGs (0-3 priority levels), a UE Buffer Status Report (BSR) (0-3) is sent on each logical channel group LCG, and according to a Quality of Service Class Identifier (QCI) level (1-256) reported by the UE, different LCs may be defined to be divided into corresponding LCGs: for example, standardized QCIs (1-9) specified in the third Generation Partnership Project (3 GPP) standard, QCIs (1-3) are mapped to LCG1, QCIs (4-6) are mapped to LCG2, QCIs (7-9) are mapped to LCG3, non-standardized QCIs (10-256) are mapped to LCG3, LCG0 is used to transmit system scheduling resource blocks (e.g., Signaling Radio Bearers (SRBs)), and BSRs 0-3 are transmitted on LCG0-3, respectively.
As can be seen from the above, in the prior art, after the network device successfully receives the SRs transmitted by the user equipment, the user equipment is placed in a queue. The network equipment places all users who send the SR into the same scheduling queue, and responds and allocates PRB resources to all the users who send the SR by using uniform priority, and along with the increase of the number of the users in the 4G network and the diversification of service types, the requirements of different users and services on scheduling delay and resources cannot be met at present.
Based on the logical channel group of the first user equipment corresponding to the scheduling request, the amount of the buffer data of the logical channel group of the first user equipment maintained by the network equipment, the time interval from the scheduling request received this time to the scheduling request of the first user equipment received last time, and the information for indicating whether the first user equipment has the potential control signaling, the scheduling priority of the user equipment which has sent the SR is determined, so that the user equipment which has sent the SR is hierarchically scheduled according to the scheduling priority, that is, the scheduling priority is respectively allocated to the scheduling queues corresponding to the scheduling priorities. The method and the device are based on the same inventive concept, and because the principles of solving the problems of the method and the device are similar, the implementation of the device and the method can be mutually referred, and repeated parts are not repeated.
Referring to fig. 3, a flowchart of a method for scheduling a resource of a user equipment according to an embodiment of the present invention is shown. The method comprises the following steps:
s301, the network device receives a scheduling request sent by the first user equipment.
S302, the network equipment determines the scheduling priority of the first user equipment according to the scheduling information; the scheduling information includes at least one of a logical channel group of the first user equipment corresponding to the scheduling request, a cache data amount of the logical channel group of the first user equipment maintained by the network equipment, a time interval between the scheduling request received this time and the scheduling request of the first user equipment received last time, and information used for indicating whether the first user equipment has a potential control signaling.
S303, the network device enqueues the first user device to a scheduling queue corresponding to the scheduling priority of the first user device, so that the network device performs resource scheduling on the user devices included in the scheduling queue based on the scheduling priority of the first user device.
In one possible implementation, the scheduling information may be allocated to each scheduling queue corresponding to fig. 2. For example, determining that a certain ue is about to drop or is in urgent need of establishing a connection according to the scheduling information, the ue may be enqueued in a scheduling queue with a higher scheduling priority than a scheduling queue corresponding to a user that sent an SR, such as a scheduling queue corresponding to a user whose LCG0 buffer data amount (which may be determined according to a BSR) is greater than 0. For another example, if it is determined that the BSR of the LCG2 is greater than 0 and the BSRs of other logical channel groups are equal to 0 for a certain ue that has sent the SR according to the scheduling information, the ue may be enqueued in the scheduling queue corresponding to the user whose BSR of the LCG2 is > 0.
Illustratively, a user equipment having sent a scheduling request is configured with N scheduling queues, N being a positive integer greater than 1. Therefore, the network device enqueues the first user equipment to the scheduling queue corresponding to the scheduling priority of the first user equipment, which can be realized by the following method:
the network equipment enqueues the first user equipment to a scheduling queue corresponding to the scheduling priority of the first user equipment in N scheduling queues configured for the user equipment which has sent the scheduling request;
the scheduling priorities corresponding to different scheduling queues are different, and N is a positive integer greater than 1.
For example, N-5, i.e. 5 scheduling queues are configured for the user equipment having sent the scheduling request. For example, in the priority hierarchy of the scheduling queue corresponding to fig. 2, the queue corresponding to the user who has transmitted the SR may be further divided into 5 levels. For another example, 5 scheduling queues may correspond to 5 locations of a user whose cache data amount of LCG0 is greater than 0, a user who has transmitted an SR, a user whose cache data amount of LCG1 is greater than 0, a user whose cache data amount of LCG2 is greater than 0, and a user whose cache data amount of LCG3 is greater than 0.
In a possible implementation manner, the determining the scheduling priority of the first user equipment according to the scheduling information may be implemented as follows:
when the first user equipment is determined to meet at least one of first level conditions, determining that the scheduling priority of the first user equipment is a first level, wherein the scheduling priority of the first level is a scheduling queue with the highest priority in the N scheduling queues:
the first ranking condition comprises at least one of:
the number of times that the first user equipment sends the scheduling request reaches a first threshold value;
the number of times that the network equipment retransmits the data packet to the first user equipment reaches a second threshold value;
the network equipment maintains that the cache data volume of the logical channel group 0 of the first user equipment is more than 0;
the time interval between the scheduling request received this time and the scheduling request of the first user equipment received last time by the network equipment is less than a third threshold value;
initiating a non-competitive random access to a reestablishing user;
user equipment of SRB data carried by the radio of the scheduled signal; alternatively, the first and second electrodes may be,
and the user equipment which does not finish the access.
Alternatively, two scheduling queues may be configured for the user equipment that transmitted the SR. Determining the scheduling priority of the first user equipment to be a second level when it is determined that the first user equipment does not satisfy any of the first level conditions. The second level is lower than the first level. The second ranking condition corresponding to the priority of the second ranking may be considered as not satisfying any of the first ranking conditions.
In a possible implementation manner, the second-level condition is a user equipment that establishes a voice session, so that when it is determined that the first user equipment does not satisfy any of the first-level conditions and it is determined that the second-level condition is satisfied, the scheduling priority of the first user equipment is determined to be the second level, and the second level is lower than the first level.

In a possible implementation manner, when the network device determines that the priority of the first user equipment is a first level, the scheduling queue corresponding to the first level may be a scheduling queue corresponding to a user whose LCG0BSR > 0. Therefore, the network device enqueues the first user equipment to the scheduling queue corresponding to the scheduling priority of the first user equipment, which can be realized by the following method:
the network equipment enqueues the first user equipment to a first scheduling queue corresponding to the scheduling priority of the first grade; the first scheduling queue further includes a second user equipment, the buffer data amount of the logical channel group 0 of the second user equipment is greater than 0, and the network equipment does not include the unprocessed scheduling request sent by the second user equipment.

The following illustrates a manner of an incoming scheduling queue of a user equipment that transmitted an SR.
Referring to fig. 4, 5 ranks, first rank to fifth rank, are configured for a user equipment that has transmitted an SR.
In fig. 4, the SR user equipment of the first level has the same priority as the user equipment with BSR >0 on logical channel group 0. In one way, the SR ue in the first level and the ue with BSR >0 in the logical channel group 0 configure a scheduling queue. In another way, the SR user equipment of the first level and the user equipment with BSR >0 in the logical channel group 0 configure two scheduling queues, and the scheduling priorities corresponding to the two scheduling queues are the same, so that separate scheduling can be performed.
As an example, allocated Physical Resource Block (PRB) resources may be calculated with a default data amount for SR user equipments belonging to the first class. When a Modulation and Coding Scheme (MCS) is selected, demodulation performance of the SR user equipment of the first level needs to be guaranteed. Illustratively, the MCS range may be configured for the first level SR user equipment.
The SR user equipment of the second level has the same priority as the user equipment with BSR >0 on logical channel 1. In one way, the SR ue of the second level and the ue with BSR >0 in the logical channel group 1 configure a scheduling queue. In another way, two scheduling queues are configured for the SR user equipment of the second level and the user equipment with BSR >0 in the logical channel group 1, and the scheduling priorities corresponding to the two scheduling queues are the same, so that separate scheduling can be performed.
As an example, the allocated PRB resources may be calculated for SR user equipments belonging to the second class with a scheduling data amount based on voice packet characteristics.
The SR user equipment of the third class individually configures one scheduling queue. As an example, the allocated PRB resources may be calculated with a default data amount for SR user equipments belonging to the third class. When the MCS is selected, the buffer status report of the user equipment can be obtained as soon as possible to carry out normal scheduling. Illustratively, the MCS range may be configured for the SR user equipment of the third level. For example, the MCS range corresponding to the third level is lower than the MCS range corresponding to the first level.
The SR user equipment of the fourth level has the same priority as the user equipment with BSR >0 on logical channel 2. In one way, the SR ue in the fourth level and the ue with BSR >0 in the logical channel group 2 configure a scheduling queue. In another way, the SR user equipment of the fourth level and the user equipment with BSR >0 in the logical channel group 2 configure two scheduling queues, and the scheduling priorities corresponding to the two scheduling queues are the same, so that separate scheduling can be performed.
The SR user equipment of the fifth level has the same priority as the user equipment with BSR >0 on logical channel 3. In one way, the SR ue in the fourth level and the ue with BSR >0 in the logical channel group 3 configure a scheduling queue. In another way, the SR user equipment of the fourth level and the user equipment with BSR >0 in the logical channel group 3 configure two scheduling queues, and the scheduling priorities corresponding to the two scheduling queues are the same, so that separate scheduling can be performed.
As an example, the allocated PRB resources may be calculated in a default scheduling manner of the general data users for SR user equipments belonging to the fourth and fifth classes. No special consideration is made in selecting the MCS.
