Background

With the development of communication technology, three service types can be supported in a fifth Generation mobile communication (5 th-Generation, abbreviated as 5G) system, including: the base station needs to simultaneously configure resources of each uplink data, including a PUSCH resource corresponding to uplink traffic data, a CG PUSCH resource and a physical uplink control channel (Physical Uplink Control Channel, abbreviated PUCCH) resource corresponding to uplink control signaling, when configuring uplink resources for User Equipment (UE).

In the conventional method, in order to avoid uplink resource collision of uplink data, a base station may configure a logical channel priority for each uplink data, so that in a media access control (Media Access Control, abbreviated as MAC) layer, a UE may sequentially perform MAC layer processing on the uplink data according to the logical channel priorities of each uplink data, and then send the processed uplink data to a physical layer of the UE.

Detailed Description

The present application will be described in further detail with reference to the drawings and examples, in order to make the objects, technical solutions and advantages of the present application more apparent. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the application.

The resource allocation method provided by the application can be applied to an application environment shown in fig. 1, and the base station 100 is in communication connection with the user equipment 200. The user device 200 may be, but is not limited to, various personal computers, notebook computers, smart phones, tablet computers, portable wearable devices, and the like. The base station may be, but not limited to, a macro base station, a micro base station, a small base station, and other types of base station equipment, and the base station 100 may be, but not limited to, a base station in a 5G network, a customer premise equipment (Customer Premise Equipment, abbreviated CPE), and the like.

In one embodiment, as shown in fig. 2, a resource allocation method is provided, which is illustrated by taking an example that the method is applied to the base station in fig. 1, and includes:

s101, determining the physical layer priority of DG service according to the scene type of dynamic scheduling DG service; the physical layer priority characterizes the degree of priority of processing of the service data in the physical layer of the user equipment UE.

The Dynamic Grant (DG) service may be an uplink DG PUSCH service that a base station schedules to a UE through DCI. The DG service may be an eMBB service scenario, a URLLC service scenario, or an eMTC service scenario, which is not limited herein. In the eMBB service scene, a higher transmission rate can be realized by adopting a larger bandwidth and improving a baseband rate, and the method is mainly used for services such as high-speed data, high-definition video and the like. The URLLC service scene can realize extremely short time delay by pursuing lower time delay and higher reliability and by means of faster scheduling, and can be used for scenes such as Internet of vehicles, remote control and the like.

The base station can determine the physical layer priority of the DG service according to the corresponding relation between the scene type of the DG service and the physical layer priority. The priority of the physical layer characterizes the priority degree of processing the data of each service in the physical layer of the UE, and the UE can determine which service uplink data to send preferentially according to the priority of the physical layer of each service.

Optionally, the scenario type of the DG service may be any one of a URLLC service scenario and an embbb service scenario, and if the scenario type of the DG service is an ultra-reliable low-delay communication URLLC scenario, the base station determines that the physical layer priority of the DG service is the first priority; if the scene type of the DG service is the enhanced mobile broadband eMBB scene, determining the physical layer priority of the DG service as a second priority; the first priority is higher than the second priority. The first priority and the second priority may be identified by 0 and 1, for example, the first priority is represented by 1, and the second priority is represented by 0; alternatively, the first priority and the second priority may also be identified by other types of priorities, for example, the first priority is identified by p1 and the second priority is identified by p 0. The specific form of the first priority and the second priority is not limited herein.

S102, transmitting downlink control signaling DCI to UE; the DCI carries the physical layer priority of DG service; the DCI is used for indicating the UE to perform uplink resource allocation based on the physical layer priority of the DG service and the preset physical layer priority of other services when the uplink resources of the DG service and the other services collide.

The base station may schedule PUSCH resources of DG traffic for the UE through DCI, and indicate physical layer priority of DG traffic to the UE through DCI. The base station may select a DCI format matching with the physical layer priority according to the physical layer priority of the DG service to send DCI, or may schedule DG services with different physical layer priorities using the same DCI format, which is not limited herein. For example, the base station may schedule DG traffic with low physical layer priority using DCI format0-1, and then schedule DG traffic with high physical layer priority using DCI format 0-2.

The physical layer Priority may be carried in a preset field in the DCI, for example, a Priority field in the DCI.

After the UE receives the DCI, it may determine DG PUSCH resources corresponding to DG services of the UE according to an instruction in the DCI, and determine whether the DG PUSCH resources collide with uplink resources of other services. The uplink resource collision may refer to a time domain resource collision or a frequency domain resource collision.

The other service may be a service of transmitting uplink data by the UE, or may be a service of controlling data transmitted by the UE; optionally, the uplink resources of other services include CG PUSCH resources of CG services, and/or PUCCH resources corresponding to PUCCH services of the UE. The CG service is a service in which a base station configures resources in advance, for example, may be CG PUSCH service that is periodically sent by a UE to the base station. The PUCCH service may be that the UE transmits HARQ-ACK to the base station, or that the UE transmits an uplink scheduling request (Scheduling Request, SR) to the base station, or that the UE transmits channel state information (Channel Status Information, CSI for short) to the base station; the type of PUCCH traffic is not limited herein.

The UE may allocate the uplink resources that collide according to a preset resource allocation policy, where the resource allocation policy may instruct the UE to perform uplink resource allocation based on the physical layer priority of each service, or instruct the UE to perform uplink resource allocation together based on the physical layer priority of each service and the logical channel priority of each service, which is not limited herein.

When the UE performs uplink resource allocation based on the physical layer priority of each service, the allocation result of the uplink resource can be determined according to the physical layer priority of the DG service and other services and the position relationship between the DG PUSCH resource and the uplink resources of other services; or determining an allocation result of the uplink resource according to the data transmission state of the uplink resource with a lower physical layer priority; for example, if the uplink data is not transmitted from the uplink resources of the service with low physical layer priority, the uplink resources of the service are canceled, and the uplink data transmission of the service with high physical layer priority is ensured.

The allocation result of the uplink resource may be that the uplink resource of the service with the higher physical layer priority is canceled, or that the uplink resource of the service with the lower physical layer priority is canceled; multiplexing of uplink resources can be realized, and uplink data transmission of DG service and other services can be ensured; or, the allocation result of the uplink resource may be to suspend the data transmission of the service with the lower physical layer priority, and continue to transmit the data of the service with the lower physical layer priority after the uplink data transmission of the service with the higher physical layer priority is completed; the form of the uplink resource allocation result is not limited herein.

According to the resource allocation method, the base station determines the physical layer priority of the DG service according to the scene type of the dynamic scheduling DG service; then, sending downlink control signaling DCI to the UE; wherein, the physical layer priority characterizes the priority degree of processing the service data in the physical layer of the user equipment UE; the DCI carries the physical layer priority of DG service; the DCI is used for indicating the UE to perform uplink resource allocation based on the physical layer priority of the DG service and the preset physical layer priority of other services when the uplink resources of the DG service and the other services collide. The base station determines the physical layer priority of the DG service according to the scene type of the DG service, and sends the physical layer priority to the UE through DCI, so that the UE can allocate uplink resources according to the physical layer priority of the DG service and the preset physical layer priority of other services when the uplink resources of the DG service and other services collide, uplink data transmission failure caused by uplink resource collision is avoided, and the transmission reliability of the uplink data is improved.

In an embodiment, based on the foregoing embodiment, the DCI may be specifically configured to instruct, when the DG service collides with uplink resources of other services, the UE to determine, in the DG service and the other services, a low priority service with a low physical layer priority, and cancel the uplink resources of the low priority service when the uplink resources of the low priority service meet a preset resource cancellation condition.

When the UE detects that the uplink resources of the DG service and other services conflict, the UE can determine which service is the low-priority service with lower physical layer priority according to the physical layer priority of the DG service and the physical layer priority of other services preset in the UE. Further, the UE may determine, according to the resource cancellation condition, an uplink resource of the low priority service, and determine whether the uplink resource meets the resource cancellation condition. If the uplink resource of the low priority service meets the resource cancellation condition, the UE may cancel the uplink resource of the low priority service, and ensure data transmission of the service with higher physical layer priority. If the uplink resource of the low priority service does not meet the resource cancellation condition, the UE may select the uplink data with the previous transmission time to transmit according to the time sequence of the uplink resource of the DG service and the uplink resource of other services.

The resource cancellation condition may be that an uplink resource of a low priority service may be cancelled when no data is transmitted in the uplink resource, or that an uplink resource of a low priority service may be cancelled when a preset condition is satisfied between the uplink resource and a current time interval, and the form of the resource cancellation condition is not limited herein.

The following describes several typical resource allocation methods in the resource conflict scenario.

In one resource conflict scenario, if the low priority service is a DG service, the DCI may instruct the UE to determine that the DG PUSCH resource meets a resource cancellation condition when a time interval between a DG PUSCH resource of the DG service and a PDCCH resource where the DCI is located is greater than a first interval threshold.

Since the UE needs a certain period of time to cancel the uplink resource, when the above time interval is too small, the UE considers that the time interval is insufficient to complete the operation of canceling the DG PUSCH resource, or before the operation of canceling the DG PUSCH resource is completed, the uplink data of the DG service has already begun to be transmitted, and at this time, the DG PUSCH cannot be canceled. When the time interval is greater than the first interval threshold, the UE may cancel the DG PUSCH resources and complete data transmission on the PUCCH resources. The first interval threshold T0 may be a fixed value, or may be determined according to a data processing duration of the UE. For example, the above T01 may be determined by the fast processing capability parameter Tproc2 of the UE, and for example, the above Tprco2 may be 5.5 symbols. T01=tproc2 or t01=tproc2+d1, where d1 may be 0 symbol, 1 symbol or 2 symbols, and is not limited herein. As shown in fig. 3, the time interval between the DG PUSCH resource and the PDCCH resource where the DCI is located is T1, where t01=tproc2+d1, and if T1 is greater than T01, the DG PUSCH resource is cancelled.

In another resource conflict scenario, if the low priority service is CG service, the DCI is specifically configured to instruct the UE to determine that the CG PUSCH resource meets a resource cancellation condition when a time interval between the CG PUSCH resource and the PDCCH resource where the DCI is located is greater than a second interval threshold.

Since the UE needs a certain period of time to cancel the uplink resource, when the above time interval is too small, the UE considers that the time interval is insufficient to complete the operation of canceling the CG PUSCH resource, or before the operation of canceling the CG PUSCH resource is completed, uplink data of the CG service has already begun to be transmitted, and at this time, the CG PUSCH cannot be canceled. When the time interval is greater than the second interval threshold, the UE may cancel the CG PUSCH resource and complete uplink data transmission on the DG PUSCH resource. The second interval threshold T02 may be a fixed value, or may be determined according to the data processing duration of the UE. For example, the T02 may be determined by the fast processing capability parameter Tproc2 of the UE, for example, the Tprco2 may be 5.5 symbols. T02=tproc2 or t02=tproc2+d2, where d2 may be 0 symbols, 1 symbol or 2 symbols, and is not limited herein. The second interval threshold may be the same as or different from the first interval threshold.

As shown in fig. 4, the time interval between the CG PUSCH resource and the PDCCH resource where the DCI is located is T2, where t02=tproc2+d2. If T2 is larger than T02, canceling CG PUSCH resources and transmitting DG PUSCH data; and if T2 is less than or equal to T02, transmitting CG PUSCH data.

In another resource conflict scene, if the low priority service is a PUCCH service, the physical layer priority of the PUCCH service is determined by the downlink service corresponding to the PUCCH service; the DCI is specifically configured to instruct the UE to determine that the PUCCH resource satisfies a resource cancellation condition when a time interval between the PUCCH resource and a PDCCH resource of the downlink service is greater than a third interval threshold.

When the above time interval is too small, the UE considers that the time interval is insufficient to complete the operation of canceling the PUCCH resource or the PUCCH data has already started to be transmitted before the operation of canceling the PUCCH resource is completed, at which time the PUCCH resource cannot be canceled. When the time interval is greater than the third interval threshold, the UE may cancel the PUCCH resource and complete uplink data transmission on the DG PUSCH resource. The second interval threshold T03 may be a fixed value, or may be determined according to a data processing duration of the UE. For example, T03 may be t02=tproc2, t02=tproc2+d3, and d3 may be 0, 1, or 2, and is not limited thereto. The third interval threshold may be the same as or different from the first interval threshold and the second interval threshold.

As shown in fig. 5, the PDCCH resource of the PUCCH resource corresponding to the downlink service is PDCCH2, the PDCCH resource of the DG service is PDCCH1, and the time interval between the PUCCH resource and the PDCCH resource of the downlink service is T3, where t03=tproc2+d3. If T3 is larger than T03, canceling the PUCCH resource and transmitting DG PUSCH data; and if T3 is less than or equal to T03, transmitting the PUCCH data.

According to the resource allocation method, the base station indicates the physical layer priority of the DG service through the DCI, so that when the uplink resources of the DG service and other services conflict, the UE can determine whether the uplink resources of the low-priority service can be canceled, and when the uplink resources of the low-priority service meet the resource canceling condition, the uplink resources of the low-priority service are canceled, thereby ensuring the data transmission of the service with high physical layer priority and reducing the uplink data transmission delay of the service with high physical layer priority.

In an embodiment, based on the foregoing embodiment, the DCI is further configured to instruct the DG service to collide with uplink resources of other services, and when the DG service has the same physical layer priority as the other services, the UE performs uplink resource multiplexing of the DG service and the other services when the DG service and the uplink resources of the other services satisfy the resource multiplexing condition.

When the UE detects that the uplink resources of the DG service and other services conflict, the UE can determine which service is the low-priority service with lower physical layer priority according to the physical layer priority of the DG service and the physical layer priority of other services preset in the UE. If the physical layer priorities of the DG service and other services are the same, the UE may further determine whether the DG service uplink resource and the other service uplink resource may implement resource multiplexing. If the uplink resources of the DG service and the uplink resources of other services meet the resource multiplexing condition, the UE can carry out resource allocation again to realize resource multiplexing. If the uplink resources of the DG service and the uplink resources of the other services do not meet the resource multiplexing condition, the UE may select, according to the time sequence of the uplink resources of the DG service and the uplink resources of the other services, uplink data with a forward transmission time for transmission.

In a resource conflict scenario, if other services are PUCCH services, and the physical layer priorities of the DG services and the PUCCH services are the same; the DCI is specifically configured to determine that a DG PUSCH resource of the PUCCH resource and the DG service satisfies a resource multiplexing condition when a time interval between PDCCH resources corresponding to the PUCCH resource and the PUCCH service is greater than a fourth interval threshold.

Since the UE needs a certain period of time for performing the resource multiplexing operation, when the above time interval is too small, the UE considers that the time interval is insufficient to complete the operation for implementing the resource multiplexing. When the above time interval is greater than the fourth interval threshold, the UE may implement multiplexing of DG PUSCH resources and PUCCH resources, e.g. transmitting PUCCH data through DG PUSCH resources. And when the time interval is larger than the fourth interval threshold, if the PUCCH resource is considered, the UE firstly transmits PUCCH data. The fourth interval threshold may be the same as or different from the third interval threshold.

As shown in fig. 5, the PDCCH resource of the PUCCH resource corresponding to the downlink service is PDCCH2, the PDCCH resource of the DG service is PDCCH1, the time interval between the PUCCH resource and the PDCCH resource of the downlink service is T3, and the fourth interval threshold is T03. If T3 is larger than T03, multiplexing DG PUSCH resources and PUCCH resources is achieved; and if T3 is less than or equal to T03, transmitting the PUCCH data.

According to the resource allocation method, the base station indicates the physical layer priority of the DG service through the DCI, so that the UE can realize the multiplexing of the uplink resources of the DG service and the other services under the condition that the uplink resources meet the resource multiplexing condition when the uplink resources of the DG service and the other services conflict with each other and the physical layer priorities of the DG service and the other services are the same, meanwhile, the uplink data of the DG service and the uplink data of the other services are transmitted, and the transmission reliability of the uplink data of each service is improved.

In one embodiment, on the basis of the above embodiment, the UE further includes a logic channel priority of DG service and a logic channel priority of other services; the logic channel priority characterizes the priority degree of processing the service data in the media intervention control (MAC) layer of the UE; the logic channel corresponding to the service with high physical layer priority has high priority; the DCI is further used to instruct the UE to process each service data in the MAC layer according to the order of the logical channel priorities.

The logical channel priority of the DG service includes a logical channel priority of a URLLC DG service and a logical channel priority of an eMBB DG service, and the logical channel priority of the other services may include logical channel priorities of CG service, HARQ-ACK, SR, CSI, and other services in a URLLC service scenario and an eMBB service scenario. The priorities of the logical channels for each service in the same service scenario may be different, for example, the priorities of the logical channels for the same service scenario are sequentially from high to low: HARQ-ACK, CG PUSCH, DG PUSCH, SR and CSI.

The logical channel priority may be ordered under the same service scenario, or may be uniformly ordered for each type of service under the URLLC service scenario and the eMBB service scenario, which is not limited herein. The priority of the logical channel corresponding to the service with the higher physical layer priority is higher, that is, the priority of the logical channel of each service in the URLLC service scene is higher than the priority of the logical channel of each service in the eMBB service scene. The priority of the logic channel can be represented by numbers or priority levels, such as A\B\C; in the case of numerical expression, a larger value of the logical channel priority may indicate a higher logical channel priority, or a smaller value of the logical channel priority may indicate a higher logical channel priority, which is not limited herein.

Fig. 6 shows a correspondence between logical channel priorities and physical layer priorities, where the priorities of the logical channels corresponding to HARQ-ACK, CG PUSCH, DG PUSCH, SR and CSI in the URLLC service scenario are sequentially 0-4, and the priorities of the logical channels corresponding to HARQ-ACK, CG PUSCH, DG PUSCH, SR and CSI in the embb service scenario are sequentially 8-12; a smaller value of the logical channel priority indicates a higher logical channel priority. The physical layer priorities corresponding to the logical channel priorities 0 to 4 may be high priority P1, and the physical layer priorities corresponding to the logical channel priorities 8 to 12 may be high priority P0.

The UE can process each service data in the MAC layer according to the order of the logic channel priority, can process the service data with higher priority of the physical layer preferentially, and avoid the priority strategy conflict of the same service data in the physical layer and the MAC layer. For example, when the UE needs to process URLLC CG PUSCH traffic and eMBB DG PUSCH traffic in the MAC layer, the UE may prioritize the processing of URLLC CG PUSCH traffic.

In the above embodiment, the UE may process each service data in the MAC layer according to the order of the logical channel priorities, so as to reduce the probability of resource collision of each service data in the physical layer.

Fig. 7 is a flow chart of a resource allocation method in an embodiment, where the embodiment relates to a manner in which a base station configures a physical layer priority of a service to a UE, and on the basis of the foregoing embodiment, as shown in fig. 7, the method further includes:

s201, determining a resource allocation strategy adopted by the UE when uplink resources conflict according to the enabling states of the physical layer priority switch and the logic channel priority switch configured by the cell network manager.

The resource allocation strategy is used for allocating uplink resources when uplink resources in the UE conflict. In the parameters configured by the cell network management, if the physical layer priority switch is enabled, the base station can determine that the physical layer priority can be configured for each service of the UE; if the logical channel priority switch is enabled, the base station may determine that logical channel priorities may be configured for each service of the UE. The base station may determine a resource allocation policy corresponding to the UE according to the above-mentioned enabling state.

Optionally, the resource allocation policy is a first policy or a second policy, where the first policy is determined based on the physical layer priority; the second policy is determined based on the physical layer priority and the logical channel priority; the first policy characterizes the UE to allocate uplink resources according to the physical layer priority of each service in the physical layer, and the second policy characterizes the UE to process each service data according to the order of the logical channel priority in the MAC layer, and then allocates uplink resources according to the physical layer priority of each service in the physical layer. If the physical layer priority switch in the cell network management configuration is enabled to be on and the logic channel priority switch is enabled to be off, the base station determines that the resource allocation policy of the UE is a first policy. If the physical layer priority switch in the cell network management configuration is enabled to be on and the logic channel priority switch is enabled to be on, the base station determines that the determined resource allocation policy of the UE is the second policy.

S202, according to a resource allocation strategy, a Radio Resource Control (RRC) reconfiguration message is sent to the UE; the RRC reconfiguration message carries the enabling state corresponding to the resource allocation strategy and the physical layer priority of the CG service.

Further, a radio resource control (Radio Resource Control, RRC) reconfiguration message is sent to the UE according to the resource allocation policy. The RRC reconfiguration message may carry the enabling state corresponding to the resource allocation policy and the physical layer priority of the CG service. If the resource allocation policy is the second policy, the RRC reconfiguration message further includes the logical channel priority of DG traffic and other traffic.

If the resource allocation policy is the first policy, the base station may perform RRC configuration with respect to the physical layer priority, and the base station may set an enabling state of the physical layer priority of the DG service through a preset field, for example, set enabling states of the eMBB DG PUSCH service and the URLLC DG PUSCH service to enabled through fields of the priority indicator Format0-1 and the priority indicator Format0-2, respectively. In addition, the base station can set the physical layer priority of the CG business through a field, for example, the physical layer priority of the CG business can be set through a phy-PrioritiyIndex field in the ConfiguredGrantConfig; the phy-PriorityIndex field is set to p0 for the ebb CG PUSCH traffic and p1 for the URLLC CG PUSCH traffic.

If the resource allocation policy is the second policy, the base station may perform RRC configuration for the physical layer priority and the logical channel priority, respectively. For the physical layer priority, the base station may set the enabling state of the physical layer priority of the DG service through a preset field, for example, the enabling states of the eMBB DG PUSCH service and the URLLC DG PUSCH service are set to enable by the fields of the priority indicator fordci-Format0-1 and the priority indicator fordci-Format0-2, respectively. In addition, the base station can also set the physical layer priority of the CG business through a preset field, for example, the physical layer priority of the CG business can be set through a phy-PrioritiyIndex field in the ConfiguredGrantConfig; the phy-PriorityIndex field is set to p0 for the ebb CG PUSCH traffic and p1 for the URLLC CG PUSCH traffic. For logical channel priority, the base station may set logical channel priority enable on through a preset field, for example, set through lch-basedPrioritization in MAC-CellGroupConfig in RRC, setting this field to enabled. In addition, the base station can also configure the logic channel priority of each service, and can set the logic channel priority of each service through the priority field in the logicalChannelConfig, and the value range of the field can be (1..16); in addition, the base station may further configure a correspondence between the logical channel priority and the physical layer priority in RRC, and the specific configuration may be as shown in fig. 6.

When uplink resources of other services of the DG service in the UE collide, the UE may determine whether each service has a physical layer priority and a logical channel priority based on configuration in RRC, and then specifically obtain values of each priority according to the RRC and the DCI, and process each service according to the values of each priority.

If the logic channel priority enable state in the RRC is enabled, the UE may process each service data in the MAC layer according to the order of the logic channel priorities based on the logic channel priorities of each service sent by the RRC. If the physical layer priority enabling state in RRC is enabled, the UE may obtain the physical layer priority of DG service in DCI, and allocate uplink resources in the physical layer according to the physical layer priority of each service based on the physical layer priority of CG service sent by RRC, where the specific allocation process may be shown in fig. 3-5.

According to the resource allocation method, the base station determines the resource allocation strategy adopted by the UE when uplink resources conflict according to the enabling states of the physical layer priority switch and the logic channel priority switch configured by the cell network manager, so that the resource allocation strategy of the UE can be flexibly adjusted according to the configuration; further, the base station sends the RRC reconfiguration message to the UE according to the resource allocation strategy, so that when the uplink resource in the UE collides with the resource, the uplink resource can be definitely allocated based on the resource allocation strategy, the transmission reliability of the uplink data is improved, and meanwhile, the data transmission of the service with higher priority of the physical layer is ensured.

In one embodiment, a resource allocation method is provided and applied to the ue in fig. 1, as shown in fig. 8, where the method includes:

s301, receiving downlink control signaling DCI sent by a base station; the DCI carries the physical layer priority of dynamic scheduling DG service; the physical layer priority of the DG service is determined based on the scenario type of the DG service, and is used to characterize the priority level of processing the service data in the physical layer of the UE.
