Description

Resource scheduling method and device, equipment and storage medium
Technical Field
Embodiments of the present disclosure relate to, but are not limited to, wireless communication systems, and in particular, to a method, an apparatus, a device, and a storage medium for scheduling resources.
Background
The existing resource scheduling scheme has the defects in supporting uplink and downlink transmission coupling and meeting industrial control service with deterministic characteristics and strict loopback time requirements.
Firstly, the uplink scheduling and the downlink scheduling of the existing scheduling scheme are decoupled, the scheduling is triggered by the conditions of an uplink buffer (buffer) and a downlink buffer (buffer), and the uplink scheduling and the downlink scheduling have no association relation. The uplink and downlink transmission time of the industrial internet cyclic communication is fixed, so that if the uplink still adopts a method of scheduling request/buffer status report, the waste of a control channel is caused, and the requirement of loop-back time is difficult to meet.
On the other hand, the current semi-static scheduling scheme is also configured by decoupling uplink and decoupling downlink. In addition, semi-static scheduling is suitable for services sent in a fixed period, such as voice, and once activated, corresponding resources are reserved periodically, but a cyclic communication command may trigger only single sending and receiving, and subsequent command triggering may not have strict periodicity, that is, a service model may not have periodicity characteristics. Thus, semi-static scheduling schemes also have certain drawbacks for industrial control scenarios.

Detailed Description
The technical solutions of the present application are further described in detail below with reference to the drawings and examples.
At the third generation partnership project (3rd Generation Partnership Project,3GPP) radio access network (Radio Access Network, RAN) conference 80, a new stand of release 16 (Rel-16) was passed, "study of industrial internet of things under the wireless system (Study on NR Industrial IoT)", which is intended to study the fifth generation (5) th Generation, 5G) new air interface physical layer, protocol stack, architecture and interface enhancements to support the needs of industrial internet of things services.
Industrial control is a typical application of industrial internet of things, and in general, the industrial control adopts a closed-loop control method. Fig. 1 is a schematic diagram of a closed-loop industrial control in the related art, as shown in fig. 1, a motion controller (Motion controller) periodically sends some instructions to an Actuator (performer) to instruct the Actuator to perform some operations (Processes), and a Sensor (Sensor) monitors the execution of the operations and feeds back the detection result to the motion controller. These operations are typically deterministic and need to be completed in a strict time period. Wherein, the liquid crystal display device comprises a liquid crystal display device,
The certainty is that the time for which the pointer is given to the command from the motion controller is fixed, and the time for which the sensor is usually fed back to the motion controller is also fixed.
By strictly periodic completion is meant that the execution of the command from the motion controller to the feedback of the sensor is required to complete within the required time, denoted by the T period (cycle).
Current industrial controls mainly employ wired ethernet technology (Sercos,
Figure BDA0001860640230000031
EtherCAT) implementation, T cycle can reach 50 microseconds (us). Conventional mobile networkMainly for wideband mobile communication, the uplink and downlink data transmission of the user has uncertainty, and there is no strict requirement on the loop back time, while the industrial control adopts a typical mechanism of cyclic communication (Cyclic Communication). Thus, how to carry industrial internet applications with certainty and strict loop-back time requirements over 5G mobile networks is a problem yet to be resolved.
The above requirements for industrial internet certainty and loop-back time (i.e. in a strict period) can be achieved by an efficient resource scheduling method, which means how to allocate radio time domain and frequency domain resources. In a mobile communication network, scheduling is generally dynamic and uplink and downlink are performed separately, and the result of scheduling is ultimately determined by a base station whether uplink or downlink.
For downlink scheduling, the base station receives the downlink wireless channel quality fed back by the terminal, decides a modulation mode and a code rate, comprehensively considers the data quantity to be transmitted, and determines the downlink scheduling resource of the terminal. For uplink scheduling, the base station receives the uplink reference signal sent by the terminal to measure the channel quality, and the base station does not know the data amount needed to be sent by the terminal at the moment, so that the terminal is required to send a buffer status report (Buffer Status Report, BSR) to the base station, and the base station determines the resources used for uplink sending by the terminal according to the BSR report and the channel quality. In addition, in order to reduce the control channel overhead, the size of the data packet such as the voice transmission (Voice over Internet Protocol, voIP) based on internet protocol (Internet Protocol, IP) is relatively fixed, and the arrival time interval satisfies a certain rule of real-time service.
The mobile communication also introduces a new scheduling mode which is different from the dynamic scheduling, namely Semi-persistent scheduling technology (Semi-Persistent Scheduling, SPS). In the SPS, during the scheduling transmission process of the base station, the eNB indicates current scheduling information of the UE through the PDCCH in the initial scheduling, and if the UE identifies that the UE is semi-persistent scheduling, the current scheduling information is saved, and the service data is sent or received at the same time-frequency resource position every fixed period.
The existing resource scheduling scheme has the defects in supporting uplink and downlink transmission coupling and meeting industrial control service with deterministic characteristics and strict loopback time requirements.
Firstly, the uplink scheduling and the downlink scheduling of the existing scheduling scheme are decoupled, the scheduling is triggered by the conditions of an uplink buffer (buffer) and a downlink buffer (buffer), and the uplink scheduling and the downlink scheduling have no association relation. The uplink and downlink transmission time of the industrial internet cyclic communication is fixed, and the scheduler of the base station can also know in advance, that is to say, the base station transmits downlink data and simultaneously knows the time and the data size of the uplink data to be transmitted in advance. Therefore, if the uplink still adopts the method of scheduling request/buffer status report, the control channel is wasted, and it is difficult to meet the requirement of loop-back time.
On the other hand, although the semi-static scheduling mechanism can reduce the overhead of the control channel caused by dynamic scheduling, the current semi-static scheduling scheme is also configured by decoupling uplink and downlink and separating. In addition, semi-static scheduling is suitable for services sent in a fixed period, such as voice, and once activated, corresponding resources are reserved periodically, but a cyclic communication command may trigger only single sending and receiving, and subsequent command triggering may not have strict periodicity, that is, a service model may not have periodicity characteristics. Thus, semi-static scheduling schemes also have certain drawbacks for industrial control scenarios.
The embodiment of the application considers the characteristics of cyclic communication transmission and combines the characteristics of mobile communication, and aims to provide a resource scheduling method for industrial Internet scenes.

During the cyclic communication process, the actuator acquires instructions from the buffer and the sensor sends out data in the buffer. Corresponding to the 5G system, from the point of view of a terminal application layer, the terminal receives the downlink data and generates uplink data to be transmitted. From the base station's point of view, the base station may get requirements regarding the cyclic transmission, such as loop time requirements, packet size, etc. The technical scheme of the embodiment of the application is as follows by integrating the characteristics of the base station and the terminal for supporting the cyclic transmission:

Meanwhile, a DL-grant/UL-grant independent transmission scheme is added, and the coupling relation of the DL-grant/UL-grant is indicated. Wherein:
1. The base station decides to circularly transmit the downlink receiving resource and the uplink sending resource of the terminal and sends the resource scheduling condition to the terminal; for example, the base station decides that the uplink resource does not need to rely on SR and BSR reporting of the terminal, and can be decided according to the service requirement and characteristics of cyclic transmission;

4) An uplink data modulation and coding mode;
step 102, the terminal receives the downlink data on the downlink resource indicated by the DCI, and sends the looped uplink data on the uplink resource indicated by the DCI.
Example 2: implicit transmission of uplink resource configuration information
Step 201, a base station decides the time and frequency resources for data reception in the downlink of a terminal, and decides the time and frequency resources for uplink loop-back data transmission;

b) Time domain resource location in uplink data resource configuration information: for receiving DCI position +n, n may be configured in the DCI, or may be in a predefined manner, e.g., type x corresponds to n being 2ms;
c) Uplink data modulation and coding scheme: type x corresponds to a fixed modulation coding mode;
In step 202, the terminal receives downlink data on the downlink resource indicated by the DCI, and sends looped uplink data on the uplink resource indicated by the DCI.
Example 3:
step 301, a base station determines time and frequency resources for receiving data in a downlink of a terminal, and determines time domain positions and frequency resources for transmitting uplink looped-back data;
for example, the downlink data reception related information is transmitted by the DCI format indicated by the downlink scheduling, and at least one of the following is included:
1) Receiving frequency resources by downlink data;
2) Modulation mode and coding mode;
3) Transmitting the time domain position by uplink data;
and the following steps: the DCI format indicated by the uplink scheduling sends the related information of uplink data transmission, and the time for sending the base station uplink DCI is not earlier than the downlink DCI of the loopback service and is not later than the uplink data receiving time of the loopback service, the terminal processing time delay and the uplink transmission time delay;
1) Uplink data transmission frequency resources;
2) Modulation mode and coding mode;
in step 302, the terminal receives downlink data from the downlink resource indicated by the DCI, acquires uplink transmission time domain information, acquires uplink frequency resource according to the DCI format indicated by the uplink scheduling, and transmits uplink data on the frequency resource corresponding to the time domain.
Example 4:
step 401, a base station determines time and frequency resources for receiving data in a downlink of a terminal, and determines time domain positions and frequency resources for transmitting uplink looped-back data;
for example: the downlink data receiving related information is sent through the DCI format indicated by the downlink scheduling, and at least one of the following information is included:
