The configuration scheduling is that the network device configures the terminal device with periodic uplink resources at a time, but delay jitter may be caused when the arrival time of the service at the terminal device side does not match the occurrence time of the uplink resources. Dynamic scheduling requires that the network device allocates uplink resources to the terminal device according to a Scheduling Request (SR) and a Buffer State Report (BSR) sent by the terminal device, so that the terminal device needs to send the SR and the BSR to the network device each time data arrives, resulting in an increase in communication delay.

Detailed Description
In some communication scenarios, the terminal device needs to obtain the uplink resource allocated to it by the network device before transmitting the uplink service, and this process is referred to as a resource scheduling process.
Common resource scheduling methods are configuration scheduling and dynamic scheduling, where the configuration scheduling is that network equipment directly configures uplink resources for terminal equipment at one time, and the terminal equipment periodically uses the uplink resources, and delay jitter may be caused when an uplink service period changes or a delay occurs. In dynamic scheduling, each time an uplink service arrives, a terminal device sends an SR request to a network device, and requests an uplink resource from the network device, after the network device requests the terminal device to configure a resource of a fixed size according to the SR request, the terminal device sends a BSR request to the network device, and a base station allocates an uplink resource of a proper size to the base station according to the BSR request. The resource request needs to be sent every time the uplink service arrives, which is easy to cause transmission delay. In some application scenarios, such as industrial application scenarios, the uplink service of the terminal device conforms to a certain rule within a certain time, and the requirements for the delay and the delay jitter of the uplink service are high, and the scheduling method is not applicable.
The embodiment of the application provides a resource scheduling method, which can reduce the transmission delay of uplink service. The technical solution in the present application will be described below with reference to the accompanying drawings.
It should be understood that the technical solution of the embodiment of the present application may be applied to a Long Term Evolution (LTE) architecture, and may also be applied to a Universal Mobile Telecommunications System (UMTS) terrestrial radio access network (UTRAN) architecture, or a radio access network (GSM EDGE radio access network, GERAN) architecture of a global system for mobile communication (GSM)/enhanced data rate GSM evolution (EDGE) system. In the UTRAN architecture or/GERAN architecture, the function of MME is completed by serving General Packet Radio Service (GPRS) support node (SGSN), and the function of SGW/PGW is completed by Gateway GPRS Support Node (GGSN). The technical solution of the embodiment of the present application may also be applied to other communication systems, for example, a Public Land Mobile Network (PLMN) system, and even a future 5G communication system or a communication system after 5G, and the like, which is not limited in the embodiment of the present application.
The embodiment of the application relates to terminal equipment. The terminal device may be a device that includes a wireless transceiving function and can cooperate with the network device to provide a communication service for a user. In particular, a terminal device may refer to a User Equipment (UE), an access terminal, a subscriber unit, a subscriber station, a mobile station, a remote terminal, a mobile device, a user terminal, a wireless communication device, a user agent, or a user equipment. For example, the terminal device may be a cellular phone, a cordless phone, a Session Initiation Protocol (SIP) phone, a Wireless Local Loop (WLL) station, a Personal Digital Assistant (PDA), a handheld device with Wireless communication function, a computing device or other processing device connected to a Wireless modem, a vehicle-mounted device, a wearable device, a terminal device in a future 5G network or a network after 5G, and the like, which is not limited in this embodiment of the application.
The embodiment of the application also relates to network equipment. The network device may be a device for communicating with the terminal device, and for example, may be a Base Transceiver Station (BTS) in a GSM system or a CDMA system, a base station (NodeB, NB) in a WCDMA system, an evolved NodeB (eNB, or eNodeB) in an LTE system, or may be a relay station, an access point, a vehicle-mounted device, a wearable device, and a network-side device in a future 5G network or a network after 5G network or a network device in a future evolved PLMN network, and the like.
The network device related in the embodiment of the present application may also be referred to as a Radio Access Network (RAN) device. The RAN equipment is connected with the terminal equipment and used for receiving data of the terminal equipment and sending the data to the core network equipment. RAN devices correspond to different devices in different communication systems, for example, a base station and a base station Controller in a 2G system, a base station and a Radio Network Controller (RNC) in a 3G system, an evolved Node B (eNB) in a 4G system, and a 5G system, for example, an Access Network device (e.g., gbb, CU, DU) in a New Radio Access Technology (NR) in a 5G system
For ease of understanding, an application scenario of the embodiment of the present application is described below by taking a 5G New Radio (NR) system as an example. Fig. 1 is a scenario applied to the embodiment of the present application, and refer to fig. 1:
the core network device 140 may include access and mobility management functions (AMFs), Session Management Functions (SMFs), unified data management elements (UPFs), and other network functions. The core network device 140 is connected to the first network device 120 and the second network device 130 through an S1 interface, wherein the first network device 120 and the second network device 130 form a wireless part of the framework. As an example, the first network device and the second network device in the embodiment of the present application may both be a gNB, and communicate therebetween through an X2 interface. Terminal device 110 may transmit upstream traffic to first network device 120 or second network device 130.
In the following, the process of configuration scheduling and dynamic scheduling is described by taking the above network architecture as an example, for configuration scheduling, the first network device 120 directly configures uplink resources for the terminal device 110 at one time, the terminal device 110 periodically uses the configured uplink resources, and when a period of the uplink resources does not match a period of an uplink service, delay jitter is easily generated. For dynamic scheduling, each time a service arrives at the terminal device 110, the first terminal device 120 needs to be requested to configure uplink resources for the service, which is prone to cause delay.
The scheduling method provided by the embodiment of the application can reduce the influence of time delay on uplink service transmission.
The following describes a scheduling method provided by an embodiment of the present application in conjunction with steps S210-S230 in fig. 2.
In step S210, the terminal device sends first information to the network device, where the first information includes mode information associated with the uplink service.
The uplink service may have a certain periodicity, and the mode information reported by the terminal device to the network device at this time may be information related to the uplink service period; the uplink traffic may not have periodicity, but a plurality of uplink traffic may form one transmission mode, or the time interval between a plurality of uplink traffic is fixed. From the whole time domain, the uplink service may have a plurality of transmission modes, each transmission mode may repeatedly appear in the time domain, and the appearance time may be regular or irregular. The mode information reported by the terminal device to the network device at this time may be information related to a transmission mode. Or the uplink service does not meet the above situation, but the terminal device may estimate the arrival time of the multiple uplink services to be performed, and the information reported by the terminal device to the network device may also include the arrival time information of the multiple uplink services. The mode information may also be understood as a shape formed by an arrangement of time instants at which the traffic occurs in the time domain, or the like.
It should be understood that the mode information may include not only the mode information of the uplink service but also the size of the uplink service data packet.
It should also be understood that the plurality of uplink services may be uplink services of the same type or uplink services of different types, which is not specifically limited in this embodiment of the present application.
For ease of understanding, the features of the uplink traffic are described in detail below in conjunction with fig. 3-5. Fig. 3 and 4 show that the uplink traffic has a periodic characteristic.
When the uplink traffic has periodicity, one uplink traffic may arrive in each period, for example, one traffic arrives in the period 310 in fig. 3, and in a subsequent process, the uplink traffic may repeatedly occur at fixed time periods 310 in a time domain. For this type of service, the terminal device may report the period and the start time of the uplink service or the arrival time of any uplink service in the multiple uplink services, so that the network device can obtain the transmission form of the uplink service according to the information.
Of course, multiple uplink services may also be reached in each period, as shown in fig. 4, multiple services occur in the period 310, and the period 310 may repeatedly occur at fixed time intervals in the subsequent process from the perspective of the time domain. At this time, in addition to reporting the length of the first period, i.e., the period 310, and the start time of the uplink service, time offset information may also be reported, where the time offset information is a time interval between a plurality of uplink services in the period 310, see time interval 311, time interval 312, and time interval 313 in fig. 4.
It should be understood that the time offset information may be a time interval between uplink services, or may also be a time interval between an uplink service and a periodic boundary, which is not specifically limited in this embodiment of the present application.
In addition, the form of the time offset information may be various, and may be a display form, for example, several values may be provided, and the several values may represent the offset information; the uplink traffic information may also be in an implicit form, for example, the uplink traffic information is represented by using bitmap information, where the bitmap information includes a plurality of bits, each bit may correspond to one time unit, a value of each bit is 0 or 1, and a bit having a value of 1 or 0 may be used to represent that there is uplink traffic in one time unit. The length of the time unit of the whole bit information may be the length of the first period, and it can be known from fig. 3 and 4 that the length of the first period may be the length of the period 310. A time interval between a bit having a value of 1 or 0 and a cycle boundary may be used as the time offset information.
In the above description, all the cases where the uplink traffic has a periodicity are described, and the embodiments of the present application may further include a case where the uplink traffic does not have the periodicity, that is, the uplink traffic does not have the periodicity, but a plurality of uplink traffic forms a transmission mode, and in the transmission mode, a time interval between the plurality of uplink traffic is fixed. The uplink traffic may be divided into a plurality of transmission modes, and each transmission mode may occur regularly or randomly in the time domain. As in the case of the uplink traffic shown in fig. 5, as shown in fig. 5, the transmission modes of the multiple uplink traffic occurring in the time interval 510 may reappear at a later time, for example, the uplink traffic of the same transmission mode as the time interval 510 occurs in the time interval 530. In this case, the terminal device allocates index information to each transmission mode, where the first information at this time may include the index information, and the index information may include not only an arrival time of a service in a certain transmission mode but also a size of the service, which is not specifically limited in this embodiment of the present application.

Optionally, the first information may further include first difference information, where the first difference information is used to indicate a difference between an uplink service arrival time and an uplink resource occurrence time.

Or the first information received by the network device may include first period information, and the time offset information at the starting time of the uplink service, where the network device may use the first period as the period of the uplink resource occurrence time and the starting time of the uplink service as the starting time of the uplink resource, so as to complete synchronization between the uplink resource occurrence time and the uplink service arrival time. If the first information also carries the size of the uplink service data packet, the network device may also configure an uplink resource with a suitable size for the terminal device to complete transmission of the uplink service, and at this time, the second information may include the start time, the first period, and the time offset information of the uplink service.
Or the first information received by the network device may include index information, the network device searches for a transmission mode corresponding to the index information, the transmission mode may indicate arrival times of multiple uplink services and sizes of multiple uplink service data packets, the network device configures uplink resources corresponding to the transmission mode for the uplink services, and the second information may include the index information, the arrival times of the multiple uplink services, or the sizes of the multiple uplink service data packets.
Or the first information received by the network device may include first difference information, and the network device adjusts the configured uplink resource according to the first difference, and carries the first difference information in the second information.
It should be understood that the first difference information is used to adjust the deviation and/or the direction of the deviation of the configured uplink resource from the original time domain position.
Or the first information received by the network device may include second difference information, and the network device adjusts the configured uplink resource according to the second difference, and carries the second difference information in the second information.
The network device may adjust the configured uplink resource according to a difference between the size of the uplink service data packet reported by the terminal device and the size of the uplink resource, so that the size of the uplink resource is matched with the size of the uplink service data packet.
It should be understood that the terminal device may report the first information through RRC signaling or MAC CE, where the MAC CE may be a BSR or a separately designed dedicated MAC CE.
