Description
Technical Field
The present application relates to the field of mobile communications technologies, and in particular, to a method for scheduling multiple resources.
Background
In order to better support low-delay data transmission, the NR introduces uplink scheduling-free transmission in the uplink. In the uplink data transmission based on the first type of configuration grant, a high-level parameter config configures all transmission resources and transmission parameters including time domain resources, frequency domain resources, reference signals for demodulation (DM RS), open loop power control, Modulation and Coding Scheme (MCS), waveforms, Redundancy Version (RV), repetition times, frequency hopping, HARQ process number, and the like. After receiving the high-level parameters, the UE can immediately use the configured transmission parameters to perform uplink data transmission on the configured time-frequency resources.
Due to the diversity of the service types, multiple configured resources are required to meet the requirements of different services. There are mainly two traffic types: the first is to support semi-persistent periodic services such as LTE and NR V2X, and the second is to support enhanced low latency high reliability (eURLLC) type services such as remote driving. The traffic models for these two traffic types can be abstracted as half-cycle behavior, such as the cycle is constant, but the packet size is rapidly changing, or both the packet size and the cycle are changing, so as to be able to divide into a plurality of cycles, and also facilitate rapid activation and deactivation of some configurations to better adapt to traffic conditions. Therefore, it is considered that the multiple configurations satisfy different traffic conditions, the parameters of the multiple different configurations, such as MCS and transmission length, are different, or the arrival time and the arrival period of the data stream are different, so the period or the transmission length of the data is also different, and the method is used to satisfy the service quality requirements of different service streams.
In the existing 3GPP standard in Rel 15 stage, when the resource to be scheduled is configured and the resource to be dynamically scheduled conflicts, the MAC layer always preferentially processes the dynamically scheduled resource, provided that the terminal has enough time to process the dynamic scheduling. In order to avoid the situation that the terminal does not have enough time to process the dynamic scheduling, the physical layer further defines that the terminal cannot be scheduled with an effective uplink configuration scheduling transmission opportunity before the dynamic scheduling is processed.
When multiple unlicensed resources are configured, it is possible that the configured resources overlap in time, for example, when eMBB and URLLC are separately scheduled, it is difficult to find and configure a resource that does not overlap in time with eMBB service for a short-period URLLC service. Therefore, when considering the time resource conflict, the terminal knows which service is allowed to be transmitted, that is, which configured exempt scheduling exempt resource is available for transmission.

Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the technical solutions of the present application will be described in detail and completely with reference to the following specific embodiments of the present application and the accompanying drawings. It should be apparent that the described embodiments are only some of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
The main idea of the invention is that when a high layer configures N authorized schedules, the authorized scheduling ID information and the priority information are configured, when a terminal receives N authorized scheduling configuration parameters, if time domain resources conflict, how to select the authorized scheduling resources with high priority to perform uplink data transmission solves the problem of conflict of a plurality of configured scheduling resources.
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is further described in detail with reference to the following embodiments.
The technical solutions provided by the embodiments of the present application are described in detail below with reference to the accompanying drawings.
The embodiment of the application provides a multi-configuration resource scheduling method, which is used for service scheduling when N authorization-free resources are configured, wherein configuration information comprises configuration identification marks and indicates sending priorities of N configurations; the ID information may be configured for N resources configured and scheduled by a high layer (referred to as "configured resources" for short in this application), corresponding to the corresponding priority. The smaller the ID number, the higher the priority. For example, configuring ConfiguredGrantConfig at a higher level adds an ID parameter, which is defined as INTEGER (1.. N), with a lower ID value and a higher priority.
Fig. 1 is a diagram illustrating the MAC layer prioritization.
Example 1: the MAC layer is prioritized first. For example, the base station configures up to 8 authorized schedules, configures 8 groups of high-layer parameters for authorized schedules, and the terminal device sends uplink data on resources corresponding to two groups of parameters, and when the two groups of resources are conflicted in time, the terminal device determines that the specific resources send uplink data according to the priority of the MAC layer.
LCP of MAC layer differentiates priority, terminal equipment maps different services to different logical channels, and different priorities of logical channels are configured for differentiation. As shown in fig. 1, LCP1 is mapped onto URLLC data transmitted based on mini-slot scheduling, and LCP2 is used to map onto eMBB data for slot scheduling, thus enabling prioritization. The two shaded portions within a slot in fig. 1 represent two types of scheduled resources.
For clarity, the abbreviation "configured resource" is used herein to indicate configured scheduling resource, that is, resource that can be used for scheduling uplink data after configuration.
Fig. 2 is a diagram illustrating that the MAC layer cannot differentiate priority.
As shown in fig. 2, when LCP2 is mapped to physical resources of URLLC and eMBB data, there is no way to distinguish with the MAC layer, and a physical layer distinguishing method needs to be enabled.
In the terminal equipment, by using a physical layer distinguishing method, when at least 2 configuration resources in the N configuration resources have conflict: firstly, determining the priority by using the period of the at least 2 configuration resources, wherein the period of the at least 2 configuration resources is the same, and the priority is determined by using at least one parameter (or the combination of the parameters) of the transmission duration, the starting time and the MCS level of the at least 2 configuration resources; when the at least one parameter (or combination of parameters) is the same, the order of sending the services by the at least 2 configuration resources is determined according to the priority represented by the configuration identifier.
Fig. 3 is a schematic diagram of uplink data transmission by scheduling resources with a short physical layer selection period.
Example 2: when the MAC layer can not distinguish the priority, the N scheduling resources are respectively generated into N corresponding PDUs, the physical layer distinguishes the PDUs according to the configuration cycles of the N configuration resources, and the priority with a short cycle is high. The specific value of N is configured by the base station, and may be 8, 2, and 16, for example. For example, the base station configures at most N — 8 grant schedules, configures 8 sets of high-level parameters for the grant schedules, and the terminal device sends uplink data on resources corresponding to two sets of parameters, and when the two sets of resources are in time conflict and the MAC layer cannot distinguish the priority of the two sets of resources, the terminal device determines the priority according to the configured period and selects the resource with the high priority to send the uplink data. As shown in fig. 3, the resource period scheduled by the first configuration is short, and when the two resources scheduled by the first configuration conflict, the resource scheduled by the first configuration is preferentially transmitted because the period is shorter than the resource scheduled by the second configuration.
Fig. 4 shows that the physical layer selects a configured resource with a short transmission duration to transmit uplink data.
Example 3: when at least 2 of the N configuration resources have the same period, the order of sending the services by the at least 2 configuration resources determines the priority according to the transmission duration, and the priority with short data transmission duration is high. Fig. 4 shows that, in the same cycle, the physical layer selects an allocation resource with a short transmission duration to transmit uplink data. For example, the base station configures up to 8 grant schedules, configures 8 sets of high-level parameters for the grant schedules, and the terminal device transmits uplink data on resources corresponding to two sets of parameters, when the two sets of resources are time-wise conflicted and the MAC layer cannot distinguish priorities of the two sets of resources, and the periods for configuring the two sets of resources are the same, and the terminal device determines the priority according to the configured uplink transmission duration and selects the resource with the high priority to transmit the uplink data. As shown in the figure, the duration of the resource scheduled by the second configuration is short, and when the two resources scheduled by the configuration conflict, the resource scheduled by the second configuration is preferentially transmitted because the transmission duration is short relative to the duration of the resource scheduled by the second configuration.
In this embodiment, the at least one parameter refers to a transmission duration. Of course, the at least one parameter may also be a data start time and an MCS level.
Fig. 5 shows that the physical layer selects a configured resource with an early start symbol to transmit uplink data.
Example 4: when at least 2 configuration resources in the N configuration resources have the same period and transmission duration, the priority of the service sending sequence of the at least 2 configuration resources is determined according to the data starting time, and the priority of the service sending sequence with the early starting time is high. Fig. 5 shows that, when the period and the transmission duration are the same, the physical layer selects the allocation resource before the start symbol to transmit uplink data. For example, the base station configures up to 8 grant schedules, configures 8 sets of high-layer parameters for the grant schedules, and the terminal device transmits uplink data on resources corresponding to two sets of parameters, when the two sets of resources are time-wise conflicted and the MAC layer cannot distinguish priorities of the two sets of resources, and the periods for configuring the two sets of resources are the same, the durations for configuring uplink transmissions of the two sets of resources are also the same, and the terminal device determines the priority according to the configured start symbol of the uplink transmission and selects the resource with the start symbol before to transmit the uplink data. As shown in the figure, the resource transmission starting symbol of the first configuration scheduling is ahead, and when the two configuration scheduling resources collide, the resource of the first configuration scheduling is preferentially transmitted because the transmission starting symbol is ahead in time relative to the resource of the second configuration scheduling.
In this embodiment, the combination of the at least one parameter refers to a combination of two parameters, i.e., a transmission duration and a data start time. In the combination of the two parameters, in connection with the previous embodiments, the priority is determined first by the transmission duration and then by the data start time.
Fig. 6 shows that the physical layer selects a configured resource with a low MCS level to transmit uplink data.
Example 5: when at least 2 configuration resources in the N configuration resources have the same period, transmission duration and starting time, the priority is determined according to the MCS level by the sequence of sending the services by the at least 2 configuration resources, and the priority with the low MCS level is high. Fig. 6 shows that the physical layer selects an allocation resource with a low MCS level to transmit uplink data when the cycle and the transmission duration are the same. For example, the base station configures up to 8 grant schedules, configures 8 sets of high-level parameters for the grant schedules, and the terminal device transmits uplink data on resources corresponding to two sets of parameters, when the two sets of resources are time-wise conflicted and the MAC layer cannot distinguish priorities of the two sets of resources, and the periods for configuring the two sets of resources are the same, the durations for configuring uplink transmissions of the two sets of resources are the same, the starting symbol times are the same, and the terminal device determines the priority according to the configured adjusted demodulation level, and selects the configured resource with a low MCS level to transmit uplink data. As shown in the figure, the MCS level (MCS ═ 10) of the first configuration is lower than the MCS level (MCS ═ 15) of the second configuration, and when the resources of the two configuration schedules collide, the resources of the first configuration schedule are preferentially transmitted because the MCS level is lower than the resources of the second configuration schedule.
In this embodiment, the combination of the at least one parameter refers to a combination of three parameters, i.e., transmission duration, data start time and MCS level. In combination with the foregoing embodiments, in the combination of the three parameters, the priority may be determined first by the transmission duration, then by the data start time, and finally by the MCS level.
Fig. 7 shows that the physical layer selects an ID with a small configuration priority value to transmit uplink data.
Example 6: when at least 2 configuration resources in the N configuration resources have the same period, transmission duration, starting time and MCS level, the order of the at least 2 configuration resources for sending the service determines the priority according to the configuration identification identifier. In the case where the period, the transmission duration, the start symbol, and the MCS level in fig. 7 are the same, the physical layer selects an ID with a smaller allocation priority value to transmit uplink data. For example, the base station configures up to 8 grant schedules, configures 8 sets of high-layer parameters for the grant schedules, and the terminal device transmits uplink data on resources corresponding to two sets of parameters, when the two sets of resources are time-wise conflicted and the MAC layer cannot distinguish priorities of the two sets of resources, and the periods for configuring the two sets of resources are the same, the durations for configuring uplink transmissions of the two sets of resources are the same, the starting symbol times are the same, the configured MCS levels are the same, and the terminal device determines the priority according to the configured priority ID and selects the resource with the smaller priority ID value to transmit the uplink data. As shown in the figure, the value of the priority ID of the first configuration scheduling resource is small, which indicates that the priority is high, and when the two configuration scheduling resources conflict, the first configuration scheduling resource is preferentially transmitted because the priority ID is smaller than the value of the second configuration scheduling resource.
In this embodiment, the combination of the at least one parameter refers to a combination of three parameters, i.e., transmission duration, data start time and MCS level. With reference to the foregoing embodiments, in the combination of the three parameters, the priority may be determined first by the transmission duration, then by the data start time, and finally by the MCS level, and when the combined values of the three parameters are the same, the order of sending the services by the at least 2 configuration resources determines the priority according to the configuration identifier.
In the solution of the present application, considering the solutions of all the foregoing embodiments, optimally, the following method may be used:
the high layer configures N independent resources, the configured content comprises N configuration identification Identifiers (IDs) which represent the transmission priorities of N configurations, and when at least 2 configuration resources in the N configuration resources have conflict in a time domain, the priority selection of the at least 2 configuration resources is carried out according to the following sequence:
the MAC layer is prioritized first. When the terminal MAC layer can process the nth (N is 1, 2., N) configured scheduling resource preferentially, setting the nth configured scheduling resource as the highest priority for transmission;
the MAC layer can not distinguish the priority of the at least 2 configuration resources, the MAC layer respectively generates the at least 2 configuration resources into at least 2 corresponding PDUs, the physical layer distinguishes the PDUs according to the configuration cycles of the at least 2 configuration resources, and the priority with short cycle is high;
when the periods are the same, distinguishing according to the data transmission duration of the at least 2 configuration resources, wherein the data transmission duration of the configuration resources is short and the priority is high;
under the condition that the period and the transmission duration are the same, distinguishing according to the data starting time of the at least 2 configuration resources, wherein the priority of the starting time of the configuration resources before is higher;

and when the period, the transmission duration, the start time and the MCS level are the same, distinguishing the resource allocation according to the configuration identifiers of the at least 2 configuration resources, for example, the configuration identifier with a small value has a high priority.

the MAC layer can not distinguish the priority of N configuration resources, the MAC layer respectively generates N corresponding PDUs from the N configuration resources, the physical layer distinguishes the PDUs according to the configuration cycles of the N configuration resources, and the priority with short cycle is high;

under the condition that the period, the transmission duration and the starting time are the same, distinguishing according to the data MCS levels of the N configuration resources, wherein the MCS level of the configuration resources is high in priority;
when the period, the transmission duration, the start time, and the MCS level are the same, the allocation identifiers of the N allocation resources are used for distinguishing, for example, the priority is higher when the value of the allocation identifier is small.
