Description

Uplink scheduling request processing method and device

Technical Field

The present invention relates to the field of communications technologies, and in particular, to a method and an apparatus for processing an uplink scheduling request.

Background

In an LTE (Long Term Evolution) system, when a UE (User Equipment) does not have service data to send, that is, when it is not necessary to upload service data to an eNodeB (Evolved Node B), the eNodeB does not need to allocate uplink resources to the UE. Otherwise, uplink resources are wasted.

Based on the above reasons, for any logical channel corresponding to the UE, when service data arrives in the buffer of the logical channel, the UE generally needs to inform the eNodeB that there is service data to be sent, and the eNodeB will correspondingly determine whether to allocate uplink resources to the UE. The UE in the RRC _ CONNECTED state and maintaining Uplink synchronization may notify the eNodeB of the need of Uplink resources by sending an SR (Scheduling Request) for sending service data on an UL-SCH (Uplink-Shared Channel). The eNodeB can be informed of the traffic data to be transmitted through the above procedure, but cannot be informed of how much traffic data to be transmitted.

Generally, the UE may inform the eNodeB how much traffic data in its Buffer needs to be transmitted by transmitting a BSR (Buffer Status Report). The above SR transmission process has a corresponding trigger mode, and especially for an NR (New Radio, New air interface) system, such as a 5G network, the trigger mode of the SR affects its service scheduling result, so how to trigger the SR and other related processes is a key problem.

In the related art, that is, in the mac layer protocol of the LTE system, the SR triggering condition is specified as follows: if the UE triggers a BSR for the first Time or triggers a BSR after the last BSR Transmission, the SR is triggered if the UE is not configured with uplink resources available for the first Transmission in the current TTI (Transmission Time Interval) and the BSR is a regular BSR.

Wherein the regular BSR may correspond to any one of the following triggering conditions: (1) the corresponding buffer of the UE is empty, but a new logic channel exists and service data needs to be sent, and at the moment, a conventional BSR is triggered; (2) if the logic channel corresponding to the UE has service data to send, but the service data arrives on the logic channel with higher priority, the logic channel with higher priority will trigger the conventional BSR; (3) the UE sends an empty BSR, mainly for the synchronization procedure of the buffer.

In the process of implementing the invention, the related technology is found to have at least the following problems:

since there are services with different priorities in the NR system, when a service with a higher priority arrives first, the service with the higher priority triggers the SR, and for a service with a lower priority that arrives later, the service cannot be triggered because the triggering condition of the conventional BSR is not satisfied, and thus the SR cannot be triggered, and further the service with the lower priority cannot be scheduled in time.

Disclosure of Invention

In the related art, the conventional BSR is triggered according to the trigger condition of the conventional BSR, and after the conventional BSR is triggered, the SR is triggered according to the trigger condition of the SR. For a service with a lower priority arriving after a service with a higher priority, the service cannot be triggered because the triggering condition of the conventional BSR is not met, so that the SR cannot be triggered, and the service with the lower priority cannot be scheduled in time. In order to solve the above problem, embodiments of the present invention provide an uplink scheduling request processing method and apparatus that overcome the above problem or at least partially solve the above problem.

The method provided by the embodiment of the invention determines whether the UE is configured with the uplink resource or not when the service data of any service reaches any logic channel for any service corresponding to any logic channel. When the UE is not configured with uplink resources, the SR is triggered based on any service. For the subsequent service with lower priority, the SR can be triggered when the UE is not configured with uplink resources, namely, a plurality of SRs can be triggered no matter the priority of the service is high or low, so that the condition that the service with lower priority cannot trigger the SR because the service with lower priority does not meet the conventional triggering condition is avoided, and the service with lower priority can be scheduled in time.

In addition, when the UE is configured with the uplink resource, if any service is the designated service, the regular BSR is triggered when the service data of the designated service arrives, and the configuration cycle of the uplink resource is greater than the preset threshold, the SR is triggered based on the designated service.

Detailed Description

The following describes embodiments of the present invention in further detail with reference to the drawings and examples. The following examples are intended to illustrate the invention but are not intended to limit the scope of the invention.

In the LTE system, when a UE has no traffic data to transmit, that is, when there is no need to upload traffic data to an eNodeB, the eNodeB does not need to allocate uplink resources to the UE. Otherwise, uplink resources are wasted. Based on the above reasons, for any logical channel corresponding to the UE, when service data arrives in the buffer of the logical channel, the UE generally needs to inform the eNodeB that there is service data to be sent, and the eNodeB will correspondingly determine whether to allocate uplink resources to the UE. The UE in the RRC _ CONNECTED state and maintaining uplink synchronization may notify the eNodeB of the need of uplink resources for transmitting traffic data on the UL-SCH by sending an SR (Scheduling Request). The eNodeB can be informed of the service data to be sent through the above procedure, and cannot be informed of how much service data to be sent. Generally, the UE can inform the eNodeB how much traffic data in its buffer needs to be transmitted by transmitting a BSR. The above SR sending process usually has a corresponding triggering mode, and especially for an NR system, such as a 5G network, the triggering mode of the SR affects its service scheduling result, so how to trigger the SR and other related processes is a key problem.

In the related art, that is, in the mac layer protocol of the LTE system, the SR triggering condition is specified as follows: if the UE triggers a BSR for the first time or triggers a BSR after the last BSR transmission, the SR is triggered if the UE is not configured with uplink resources available for the first transmission in the current TTI and the BSR is a regular BSR. Wherein the regular BSR may correspond to any one of the following triggering conditions: (1) the corresponding buffer of the UE is empty, but a new logic channel exists and service data needs to be sent, and at the moment, a conventional BSR is triggered; (2) if the logic channel corresponding to the UE has service data to send, but the service data arrives on the logic channel with higher priority, the logic channel with higher priority will trigger the conventional BSR; (3) the UE sends an empty BSR, mainly for the synchronization procedure of the buffer.

To solve the problems in the related art, embodiments of the present invention provide a method for processing an uplink scheduling request, where the method is applicable to a UE. Before describing the contents of the embodiments and the following embodiments of the present invention, concepts that may be involved in the embodiments and the following embodiments of the present invention will be described.

SR, called Scheduling Request, is a way for a UE to Request resources from an eNodeB for transmitting data. The scheduling request process of the current LTE system mainly includes: the UE in the online state may periodically acquire the SR resource allocated by the eNodeB in the uplink resource. When the UE needs to send uplink data, the SR may be triggered first, and the SR is sent to the eNodeB. After receiving the SR, the eNodeB schedules the UE that transmits the SR, so that the UE starts to transmit uplink data.

The SR belongs to information of a Physical layer, and the UE transmits the SR without using an RB (resource Block) resource and may transmit the SR through a PUCCH (Physical Uplink Control CHannel). After the eNodeB successfully decodes the SR signal of a certain UE, the UE may be allocated RB resources through DCI0(DCI0 is Downlink control information, a format of DCI), but the eNodeB cannot be guaranteed to allocate RBs each time. Sometimes the UE sends the SR signal but the eNodeB does not decode it. Even sometimes, in order to acquire the uplink RB resource, the UE needs to transmit the SR signal multiple times, i.e., retransmit the SR signal multiple times.

UE, called User Equipment (UE), is an important concept in mobile communication, and in a wireless communication network, a UE is called UE.

Compared with the existing Node B in 3G, the Evolved Node B (Evolved Node B) integrates the functions of part of RNC (radio network controller), and reduces the level of a protocol during communication.

eNodeB, named as Evolved Node B. Abbreviated as eNB, the name of a base station in LTE. The functions of the eNB include: RRM (Radio Resource Management) function; IP header compression and user data stream encryption; selecting an MME (Mobility Management Entity) when the UE is attached; scheduling transmission of paging information; scheduling transmission of broadcast information; and setting and providing measurements of the eNB, etc.

A logical channel through which the MAC provides a data transfer service to an upper layer. Logical channels can be generally classified into two categories: control channels and traffic channels. The control channel is used to transmit control plane information and the traffic channel is used to transmit user plane information.

Wherein the control channel includes:

broadcast control channel: a downlink channel broadcasting system control information.

Paging control channel: a downlink channel on which paging information is transmitted.

Dedicated control channels: a point-to-point bi-directional channel for transmitting dedicated control information, which is established when the UE has an RRC connection.

Common control channel: a bi-directional channel for transmitting control information between the network and the UE before the radio resource control connection is established.

Multicast control channel: model base management system scheduling and control information transmission from the network to the UE uses a point-to-multipoint downlink channel.

Wherein, the traffic channel includes:

dedicated traffic channels: a dedicated traffic channel is a point-to-point channel dedicated to one UE for the transmission of user information. The channel exists both in the uplink and in the downlink.

Multicast traffic channel: point-to-multipoint downlink.

BSR, full Buffer Status Report, i.e. Buffer Status Report. And the eNodeB allocates downlink or uplink wireless resources to each UE according to the downlink buffer data in the eNodeB and the BSR received from the UE.

The TTI is called Transmission Time Interval (TTI), i.e., Transmission Time Interval. TTI is a parameter in the universal mobile telecommunications system and refers to the length of an independently decoded transmission in a radio link. Where TTI is related to the size of the data block from the higher network layer to the radio link layer.

RRC _ CONNECTED, one of the management states of the LTE system. In addition, a state RRC _ IDLE is included.

For 5G networks, ITU-R defines 3 major application scenarios of future 5G, which are enhanced Mobile internet service embb (enhanced Mobile broadband), mass-connected internet of things service mtc (massive machine type communication), and Ultra-high reliability and Ultra-Low delay service urlmlc (Ultra Reliable and Low latency communication). For the three application scenarios, the capability requirement of the 5G network is defined from 8 dimensions such as throughput rate, time delay, connection density and spectral efficiency improvement.

Based on the above-defined content, referring to fig. 1, the uplink scheduling request processing method provided by the embodiment of the present invention includes: 101, for any service corresponding to any logical channel, when the service data of any service reaches any logical channel, determining whether the UE is configured with uplink resources; 102. when the UE is not configured with uplink resources, triggering the SR based on any service; 103. when the UE is configured with the uplink resource, if any service is a designated service, the regular BSR is triggered when service data of the designated service arrives, and the configuration cycle of the uplink resource is greater than a preset threshold, the SR is triggered based on the designated service.

As an alternative embodiment, the method further comprises:

All the above-mentioned optional technical solutions can be combined arbitrarily to form the optional embodiments of the present invention, and are not described herein again.

Based on the content in the foregoing embodiments, an embodiment of the present invention provides a method for processing an uplink scheduling request, where the method is applicable to a UE. Referring to fig. 2, the method includes: 201. for any service corresponding to any logical channel, when the service data of any service reaches any logical channel, determining whether the UE is configured with uplink resources; 202. when the UE is not configured with uplink resources, triggering the SR based on any service; 203. when the UE is configured with the uplink resource, if any service is a designated service, the conventional BSR is triggered when the service data of the designated service arrives, and the configuration cycle of the uplink resource is greater than a preset threshold value, the SR is triggered based on the designated service; 204. after the SR is triggered, for any two types of services, when service data arrives in a cache of a logic channel corresponding to the first type of service, the SR is sent to an eNodeB based on the first type of service through SR resources corresponding to the first type of service and the second type of service.

In step 201, for any service corresponding to any logical channel, when the service data of any service reaches any logical channel, it is determined whether the UE has been configured with the uplink resource.

The process of applying for uplink resource by the UE is mainly as follows: the UE inserts a BSR control unit in a packet data unit of the MAC layer to inform the eNodeB that some data currently need to be transmitted in one or more logical channel groups of the UE, so that the eNodeB is applied for some RB resources. By means of the mode of transmitting the BSR control unit, the eNodeB can know the data volume required to be transmitted by the UE, and can allocate the RB resources in a targeted mode.

However, since the UE sends the BSR control element, the UE itself also needs uplink RB resources, and if the UE does not have any uplink RB resources, the BSR cannot be sent. At this time, the UE may send a resource application to the eNodeB in such a manner as follows. By sending the SR to the eNodeB, when the UE cannot send the BSR to apply for the RB resource, the resource can be applied in a mode of sending the SR. Since the BSR is encapsulated in the MAC PDU, it is transmitted to the eNodeB over the PUSCH channel, thereby requiring uplink RB resources. The SR signal can be transmitted in the PUCCH control channel, and the resource application can be issued to the eNodeB without uplink RB resources. However, since the eNodeB receives only one SR signal, it does not know how many bytes of data the UE needs to upload next, and thus it is not clear how many resources the UE allocates are suitable. Therefore, the subsequent UE may still need to send a BSR to apply for more uplink resources. After receiving the SR request of the UE, the eNodeB allocates how many RB resources, which is determined by the algorithm of the equipment manufacturer. Generally, after receiving the SR signal, the eNodeB allocates RB resources at least to satisfy BSR transmission.

Of course, there are other application methods besides the above two methods for applying for uplink RB resources. And when the UE does not acquire the RB resources allocated by the eNodeB, determining that the UE is not configured with the uplink resources. Otherwise, determining that the UE is configured with the uplink resource.

In step 202, when the UE is not configured with uplink resources, the SR is triggered based on any service.

The SR may be triggered when the UE is not configured with uplink resources. When the UE triggers an SR, the SR is in a "Pending" state, which means that the UE prepares but has not sent the SR to the eNodeB. When the UE has assembled a MAC PDU that includes the most recently triggered BSR control element, or the resource provided by the uplink grant can accommodate all data to be transmitted, the SR in the "Pending" state is cancelled. At the same time, the prohibit timer sr-ProhibitTimer is also stopped. In other words, if the BSR is ready to be transmitted or the current RB resource is already sufficient, there is no need to apply for resources through the SR any more.

For the sr-ProhibitTimer timer: the SR-ProhibitTimer timer is used to monitor the SR signal transmitted in the PUCCH, and when the timer is running, the SR cannot be transmitted. When the timer times out, the UE needs to resend the SR until the maximum sending times dsr-TransMax is reached. The value of the sr-ProhibitTimer timer is configured by RRC and is transmitted to the UE in the MAC-MainConfig cell.

In step 203, when the UE has been configured with the uplink resource, if any service is the designated service, the regular BSR is triggered when the service data of the designated service arrives, and the configuration cycle of the uplink resource is greater than the preset threshold, the SR is triggered based on the designated service.

The step 202 is mainly a process of triggering the SR when the UE is not configured with the uplink resource. From the content of the above embodiment, the uRLLC service corresponds to an application scenario with ultra-high reliability and ultra-low time delay. For the NR system, since the uRLLC service is not divided in the previous LTE protocol, when uplink resources are configured for services such as VoLTE, triggering of an SR corresponding to the uRLLC service is prevented. This may cause the time delay of the uRLLC service to increase, and even to lose packets, which is inconsistent with the application scenario for which the uRLLC service is applicable. As can be seen from the above description, when the UE is configured with uplink resources, there is still a need to trigger SR for some specific services. Correspondingly, the embodiment of the invention also provides a method for triggering the SR for the specified service, namely the content in the step. Note that this step is executed when the UE is already configured with uplink resources, and the above step 202 is executed when the UE is not configured with uplink resources, and both steps are branching steps in the different cases.

It should be noted that the urrllc service in the foregoing process may be one of the designated services, and the designated service may correspond to an application scenario with high reliability and ultra-low time delay. Through the process, the specified service can be ensured to be triggered SR in time. When determining whether the configuration period of the uplink resource is greater than the preset threshold, the preset threshold in the embodiment of the present invention may be configured in advance by the eNodeB, or may be predefined by a communication protocol, which is not specifically limited in the embodiment of the present invention.

For the processing procedure of the uplink scheduling request, in addition to the SR triggering procedure described above, the UE may also send an SR, that is, after the SR is triggered, the UE may also send an SR to the eNodeB to apply for uplink resources. Correspondingly, the embodiment of the invention also provides a method for sending the uplink scheduling request, and the specific process is detailed in the following steps.

In step 204, after the SR is triggered, for any two types of services, when service data arrives in the cache of the logical channel corresponding to the first type of service, the SR is sent to the eNodeB based on the first type of service through SR resources corresponding to the first type of service and the second type of service.

The step is mainly a process that after the SR is triggered, the UE selects the SR resource to send the SR. It should be noted that, in the embodiments and subsequent embodiments of the present invention, after the SR is triggered in the SR triggering manner provided in the above embodiments, the SR is sent in the SR sending resource manner provided in the embodiments and subsequent embodiments. Of course, the SR resource sending process provided in this embodiment and the subsequent embodiments may also be executed after the execution of other SR triggering processes is completed, that is, the SR triggering process and the SR sending process provided in this embodiment and the subsequent embodiments may be executed separately and independently. For a detailed description of the process of sending the SR resource by the UE, the process of sending the SR resource by the UE in this step can be referred to the contents of the following embodiments, which will not be described herein.

Based on the content in the foregoing embodiments, an embodiment of the present invention provides a method for processing an uplink scheduling request, where the method is applicable to a UE. The method comprises the following steps: after the SR is triggered, for any two types of services, when service data arrives in a logic channel corresponding to the first type of service, the SR is sent to the eNodeB through SR resources corresponding to the first type of service and the second type of service.

As an optional embodiment, sending the SR to the eNodeB through the SR resources corresponding to the first type of service and the second type of service includes:

As an optional embodiment, the first parameter set includes at least one first parameter group, the second parameter set includes at least one second parameter group, and the sending of the SR to the eNodeB is based on the SR resource status corresponding to the first parameter set and the SR resource status corresponding to the second parameter set, including:

As an alternative embodiment, the sending the SR to the eNodeB based on the SR resource status of each first parameter group and each second parameter group includes:

As an alternative embodiment, the sending the SR to the eNodeB based on all the first target parameter sets includes:

As an alternative embodiment, the sending the SR to the eNodeB based on all the second target parameter sets includes:

As an optional embodiment, initiating a random access procedure to an eNodeB based on PRACH resources correspondingly configured for each first parameter group and each second parameter group, includes:

As an alternative embodiment, the method further comprises:

Based on the content in the foregoing embodiments, an embodiment of the present invention provides a method for processing an uplink scheduling request, where the method is applicable to a UE. Referring to fig. 3, the method includes: 301, after triggering SR, for any two types of services, when service data arrives in a logical channel corresponding to a first type of service, sending SR to eNodeB through SR resources corresponding to the first type of service and a second type of service; 302, for any parameter set of the first parameter set and the second parameter set, determining priority information corresponding to any parameter set; 303, sending priority information corresponding to any parameter group to the eNodeB.

In step 301, after triggering the SR, for any two types of services, when service data arrives in a logical channel corresponding to the first type of service, the SR is sent to the eNodeB through SR resources corresponding to the first type of service and the second type of service.

In the embodiment of the present invention, the SR resource may be any one of resources in a time domain, a frequency domain, a code domain, a space domain, and the like, or an organization of several resources, and the embodiment of the present invention does not specifically limit the type of the SR resource. For example, the SR resource may be periodic, occurring once every n subframes. The period of the SR may be determined by IE: sr-ConfigIndex field of SchedulingRequestConfig.

In this step, the first type of traffic has a higher priority than the second type of traffic. The embodiment of the present invention does not specifically limit the types of the first type service and the second type service, for example, the first type service may include a urrllc service, and the second type service may include an eMBB service. It should be noted that any two types of services in the embodiment of the present invention are any two types of services in all services supported by the NR system. Besides the uRLLC service, the first type of service may also include other services with priorities equivalent to the uRLLC service. The second type of service may include other services corresponding to the priority of the eMBB service, in addition to the eMBB service having a lower priority than the urrllc service. This step mainly illustrates that the first type of service can send the SR to the eNodeB through the SR resource corresponding to itself, and can also send the SR to the eNodeB through the SR resource corresponding to the second type of service. Of course, if there is a third type of service with a lower priority than the second type of service, when the first type of service needs to send the SR, the SR may also be sent to the eNodeB through the SR resource corresponding to the third type of service, and is not limited to the SR resources of the first type of service and the second type of service. I.e. "first class" and "second class" are used only to distinguish between different types of traffic. Specifically, in an actual implementation process, if the first type of service needs to send the SR, the SR may be sent to the eNodeB through SR resources of other types of services, that is, in addition to the second type of service, SR resources corresponding to types of services such as a third type of service and a fourth type of service may also be utilized, which is not specifically limited in this embodiment of the present invention.

When the UE sends the SR corresponding to the first type of service to the eNodeB, the UE needs to utilize the SR resource. Accordingly, the embodiment of the present invention does not specifically limit the way in which the UE sends the SR to the eNodeB through the SR resources corresponding to the first type of service and the second type of service, including but not limited to: determining a first parameter set applicable to a logical channel corresponding to a first type of service, and determining a second parameter set applicable to a logical channel corresponding to a second type of service; based on the SR resource state corresponding to the first parameter set and the SR resource state corresponding to the second parameter set, the SR is sent to the eNodeB; the SR resource status is one of the following two statuses, including having SR resources and not having SR resources.

The first parameter set comprises at least one first parameter set, and the second parameter set comprises at least one second parameter set. It should be noted that the terms "first" and "second" are only used to distinguish the parameter sets or parameter sets applicable to different logical channels, and do not limit the specific contents of the parameter sets or parameter sets. In addition, the parameter set can be represented by "numerology/TTItype", and there may be multiple applicable "numerology/TTI types" for one logical channel, i.e. corresponding to multiple parameter sets. The embodiment of the present invention does not specifically limit the number of first parameter sets in the first parameter set, and does not specifically limit the number of second parameter sets in the second parameter set. "numerology" refers to a communication system parameter set. The "numerology" may include subcarrier spacing, symbol length, cyclic prefix length, etc. at the same time, which correspond to the data transmission strategy. For example, the first parameter set may include two "numerology/TTI types," which may be referred to simply as n1 and n2, respectively.

Compared with OFDM under 4G, F-OFDM under 5G benefits from numerology flexibility and has greater advantages. Specifically, the design of the basic waveform of the 5G network is a basis for realizing a unified air interface, and meanwhile, the flexibility and the utilization efficiency of the frequency spectrum are considered. For the OFDM of the lower 4G, the OFDM modulates high-speed data to mutually orthogonal subcarriers through serial/parallel conversion, and introduces cyclic prefixes, thereby better solving the problem of intersymbol crosstalk. But the most important problem with OFDM is that it is not flexible enough. In the future, different applications have different requirements on the air interface technology, for example, the car networking service with millisecond-level time delay requires a very short time domain Symbol and TTI, which requires a subcarrier interval with a wider frequency domain; in the multi-connection scene of the internet of things, the data volume transmitted by a single sensor is extremely low, but the requirement on the overall connection number of the system is high, so that a narrower subcarrier interval needs to be configured in the frequency domain. In the time domain, the lengths of Symbol and TTI can be long enough, so that the problem of intersymbol interference is hardly considered, and a CP is not required to be introduced. Meanwhile, asynchronous operation can also solve the problem of power saving of the terminal.

For the above flexible requirements, 4G OFDM cannot be satisfied. The time frequency resource allocation mode of OFDM is fixed 15KHz on the frequency domain subcarrier bandwidth, and after the subcarrier bandwidth is determined, the length of time domain Symbol, CP length and other parameters are basically determined. And the F-OFDM can provide different subcarrier spacing and numerology for different services so as to meet the time-frequency resource requirements of the different services.

As can be seen from the above, different numerologies are provided according to business requirements, so that the flexibility of business processing can be improved. Accordingly, when the UE sends the SR based on the parameter sets, the embodiment of the present invention does not specifically limit the manner in which the UE sends the SR to the eNodeB based on the SR resource state corresponding to the first parameter set and the SR resource state corresponding to the second parameter set, including but not limited to: determining an SR resource state corresponding to each first parameter group in the first parameter set, and determining an SR resource state corresponding to each second parameter group in the second parameter set; and transmitting the SR to the eNodeB based on the SR resource state of each first parameter group and each second parameter group.

For the parameter groups corresponding to different types of services, resources for transmitting the SR may be configured as a transmission policy, so that the SR resource status of each parameter group may be determined in the foregoing process. Some of the parameter sets may not have SR resources, and some of the parameter sets may have SR resources. Accordingly, the SR resource state is any one of the following two states including having an SR resource and not having an SR resource.

Because the parameter set corresponds to different states of the SR resources, the UE can correspondingly select the SR resources. Based on this, the embodiment of the present invention does not specifically limit the manner in which the UE sends the SR to the eNodeB based on the SR resource status of each first parameter group and each second parameter group, and includes but is not limited to: when the first parameter set includes the first parameter group having the SR resource, the first parameter group having the SR resource is set as a first target parameter group, and the SR is transmitted to the eNodeB based on all the first target parameter groups.

In the foregoing process, the corresponding number of "all" is one or more, that is, when the SR is transmitted to the eNodeB, the number of the first target parameter group may be one or more, and this is not specifically limited in the embodiment of the present invention.

For example, taking the first parameter set included in the first parameter set as n1 and n2 as an example, it can be determined whether there is SR resource in n1 and n2, respectively. When the first parameter sets n1 and n2 both have SR resources, the UE may take both n1 and n2 as the first target reference set and send an SR to the eNodeB based on n1 and n 2.

After determining the first target parameter group, the UE may transmit the SR according to the first target parameter group. Accordingly, when the UE sends the SR according to the first target parameter group, the embodiment of the present invention does not specifically limit the way for the UE to send the SR to the eNodeB based on all the first target parameter groups, including but not limited to: and selecting at least one first target parameter group from all the first target parameter groups, and sending the SR to the eNodeB based on the SR resource corresponding to the selected first target parameter group.

For example, the first target parameter set is n1 and n 2. In transmitting the SR to the eNodeB, the UE may transmit the SR to the eNodeB based on the SR resource corresponding to n1, and may also transmit the SR to the eNodeB based on the SR resource corresponding to n2, that is, alternatively. Of course, the UE may also transmit the SRs to the eNodeB by using the SR resources corresponding to n1 and n2 at the same time.

Considering that there may be no first parameter set having SR resources in the first parameter set to which the logical channel corresponding to the first type of service is applicable, the UE may further select SR resources of a second parameter set in the second parameter set to transmit the SR. Based on this, when the UE sends the SR based on the second parameter set, the embodiment of the present invention does not specifically limit the manner in which the UE sends the SR to the eNodeB based on the SR resource status of each first parameter set and each second parameter set, and includes but is not limited to: when the first parameter set does not have the first parameter group with the SR resources and the second parameter set has the second parameter group with the SR resources, the second parameter group with the SR resources is used as a second target parameter group, and the SR is transmitted to the eNodeB based on all the second target parameter groups.

In the foregoing process, the corresponding number of "all" is one or more, that is, when the SR is transmitted to the eNodeB, the number of the second target parameter group may be one or more, and this is not specifically limited in the embodiment of the present invention.

After determining the second target parameter set, the UE may transmit the SR according to the second target parameter set. Accordingly, when the UE sends the SR according to the second target parameter group, the embodiment of the present invention does not specifically limit the way for the UE to send the SR to the eNodeB based on all the second target parameter groups, including but not limited to: and selecting at least one second target parameter group from all the second target parameter groups, and sending the SR to the eNodeB based on the SR resource corresponding to the selected second target parameter group.

For example, the second target parameter set is n2 and n 3. When the UE sends the SR to the eNodeB, the UE may select the SR resource corresponding to n3 since it has been previously determined that n1 and n2 do not have the SR resource. Note that, when there are other second target parameter groups having SR resources in addition to n3, the UE may also select SR resources corresponding to other second target parameter groups. In addition, there may be other types of traffic having lower priority than the first type of traffic, in addition to the second type of traffic having lower priority than the first type of traffic. For these types of services, the UE may also select SR resources corresponding to the target parameter set for these types of services.

As can be seen from the above description, there may be a plurality of selectable target parameter sets, so that the UE may select the target parameter set randomly or in a priority manner, which is not specifically limited in the embodiment of the present invention. The priority may be preset, and the embodiment of the present invention does not specifically limit the setting manner.

The foregoing content mainly includes an SR transmission process corresponding to a second parameter set having SR resources in the first parameter set or the second parameter set, and the second parameter set may not have the SR resources in the second parameter set. At this time, the UE cannot transmit the SR. In order to enable the UE to continue applying for the uplink resource in view of the above situation, embodiments of the present invention further provide a method for enabling the UE to apply for the uplink resource through a random access process. Accordingly, the embodiment of the present invention does not specifically limit the manner in which the UE sends the SR to the eNodeB based on the SR resource status of each first parameter group and each second parameter group, and includes but is not limited to: and when the first parameter set does not have the first parameter set with the SR resources and the second parameter set does not have the second parameter set with the SR resources, initiating a random access process to the eNodeB based on the PRACH resources correspondingly configured by each first parameter set and each second parameter set.

The random access is a necessary process for establishing a wireless link between the UE and the eNodeB, and only after the random access is completed, the eNodeB and the UE can perform data interaction normally. The UE can implement two basic functions through random access:

(1) and uplink synchronization with the eNB is achieved, and once uplink is out of synchronization, the UE can only transmit data in the PRACH.

(2) Apply for uplink resource (UL _ GRANT).

The process of sending the SR to the eNodeB is mainly for applying for the uplink resource, and the function implemented by the UE may know that, when the first parameter set does not have the first parameter set having the SR resource and the second parameter set does not have the second parameter set having the SR resource, the UE may apply for the uplink resource through a random access process.

Since there may be a plurality of parameter sets configured with PRACH resources correspondingly, the UE may select the PRACH resource to initiate a random access procedure to the eNodeB. Accordingly, when the UE initiates the random access procedure, the embodiment of the present invention does not specifically limit the manner in which the UE initiates the random access procedure to the eNodeB based on the PRACH resource correspondingly configured by each first parameter group and each second parameter group, including but not limited to: and initiating a random access process to the eNodeB sequentially through the corresponding configured PRACH resources according to the priority order of each first parameter group and each second parameter group.

For example, if the parameter sets corresponding to the logical channels to which data arrives are the first parameter set and the second parameter set, respectively, the first parameter set in the first parameter set is n1 and n2, and the second parameter set in the second parameter set is n 3. The UE may select PRACH resources according to the priority order of random access corresponding to n1, n2, and n 3.

The priority order of the random access corresponding to n1, n2, and n3 can be determined based on the service characteristics and the parameters in the numerology. For example, if the uRLLC service has data to arrive, the applicable subcarrier spacing may be 60HZ based on the characteristics of high reliability and low delay of the uRLLC service. And the subcarrier spacing corresponding to n1 is 60HZ, which is consistent with the use of the uRLLC service, and therefore the priority is highest. n2 corresponds to a sub-carrier spacing of 30HZ, with some difference in priority order from the uRLLC service. And the subcarrier interval corresponding to n3 is 15HZ, and has a large applicable difference with the uRLLC service, so that the priority is the lowest.

If the priorities of the random accesses corresponding to n1, n2, and n3 are sequentially decreased, the UE may select the PRACH resource corresponding to n1 first. If n1 does not have corresponding PRACH resource, the UE can select the PRACH resource corresponding to n 2. If n2 has a corresponding configured PRACH resource, the UE may initiate a random access procedure based on the n2 corresponding configured PRACH resource. If n2 does not have the corresponding PRACH resource configured, the UE may continue to select the PRACH resource correspondingly configured to n 3. Repeating the above processes until the PRACH resource is selected, and completing the random access process.

It should be noted that, when none of n1, n2, and n3 has the PRACH resource configured correspondingly, the UE may further select the PRACH resource configured correspondingly to the parameter set corresponding to the other logical channel, so as to initiate the random access procedure. When selecting other logical channels, the UE may also select the logical channels according to the priority of the logical channels, which is not specifically limited in this embodiment of the present invention.

Since the parameter sets in the first parameter set and the second parameter set are usually configured to the UE by the system, some parameter sets (i.e. numerology) may be better fit with the service characteristics of the UE. At this time, the UE may use these parameter sets as preferred parameter sets for the corresponding services. For some services, the configured parameter set may be relatively inappropriate, so that the UE may use the parameter set as an optional parameter set for the corresponding service. For some services, the configured parameter set may be completely unavailable, so that the UE may use the parameter set as an unavailable parameter set for the corresponding service.

For example, if the subcarrier spacing applicable to the uRLLC service is 60HZ and the subcarrier spacing corresponding to n1 is 60HZ, the UE may use n1 as the preferred parameter set in accordance with the uRLLC service. The subcarrier spacing corresponding to n2 is 30HZ, and has a bit difference from the uRLLC service, so that the UE can use n2 as an optional parameter set. And the subcarrier spacing corresponding to n3 is 15HZ, which is a large difference from the use of the uRLLC service, so that the UE can use n3 as an unavailable parameter set.

As can be seen from the above, different sets of parameters may correspond to different fitness levels for different services. The suitability of the parameter set may be represented by priority information, which is not particularly limited in the embodiment of the present invention. The priority information may be divided into "preferred", "optional", and "unavailable" according to the above. Of course, other division manners may also be available, and the embodiment of the present invention does not specifically limit the division manner of the priority information.

In order to enable the eNodeB to know that the combination of the configuration parameter sets is appropriate, so as to facilitate better subsequent configuration, an embodiment of the present invention further provides a method for the UE to indicate the priority of the parameter sets to the eNodeB, where the specific process is detailed in the subsequent steps. It should be noted that, for the process of indicating the parameter group priority to the eNodeB by the UE, the process may be performed simultaneously when the SR is transmitted, or may be performed before or after the SR is transmitted, not necessarily according to the order described in the steps in the embodiment of the present invention.

In step 302, for any parameter set of the first parameter set and the second parameter set, priority information corresponding to any parameter set is determined.

For convenience of explanation, the uRLLC service is taken as an example. For the urlllc service, there may be a parameter set (i.e., "numerology/TTI type") that is suitable for high reliability and ultra-low latency application scenarios. For such parameter sets, the UE may treat it as a "preferred" parameter set, e.g., n1 may be treated as a "preferred" parameter set. For parameter sets that are less suitable for high reliability and ultra-low latency application scenarios, the UE may treat such parameter sets as "optional" parameter sets, e.g., n2 may be treated as an "optional" parameter set. For parameter sets that do not apply to high reliability and ultra-low latency application scenarios, the UE may treat such parameter sets as "unavailable" parameter sets, e.g., n3 may be treated as "unavailable" parameter sets. According to the above process, for the system configuration parameter sets, the UE may determine the priority information corresponding to each parameter set accordingly.

In step 303, priority information corresponding to any parameter set is sent to the eNodeB.

After determining the priority information corresponding to each parameter set, the UE may send the priority information corresponding to each parameter set to the eNodeB. As can be seen from the above-mentioned contents in step 301, the process of the UE indicating the parameter group priority to the eNodeB may be executed when transmitting the SR, or may be executed before or after. The method for sending the parameter set corresponding to the priority information to the eNodeB by the UE may be set according to requirements, which is not specifically limited in the embodiment of the present invention. For convenience of understanding, in the embodiments of the present invention, a process of transmitting, by a UE, parameter set priority information to an eNodeB is described as an example when the UE indicates the parameter set priority to the eNodeB when transmitting an SR.

Specifically, since the UE is also carried over radio waves when transmitting the SR to the eNodeB. The radio waves will generally have a corresponding phase, so that the UE can indicate the priority of the parameter set by adjusting the phase of the radio wave transmitting the bearer SR when transmitting the SR. The priority information may correspond to a phase, or a phase angle. The embodiment of the present invention is not particularly limited in this respect as to the specific corresponding manner. For example, since the waveform cycle is 360 degrees, the phase angle can be divided into 0 degrees, 180 degrees and 360 degrees, which respectively correspond to the three kinds of priority information divided in the above. Wherein, 0 degree can correspond to 'preferred', 180 degrees can correspond to 'optional', and 360 degrees can correspond to 'unavailable'.

In combination with the above process of selecting SR resources by the UE to send an SR, a process of indicating the parameter group priority from the UE to the eNodeB is illustrated. For example, if the parameter sets n1 and n2 both have SR resources, and the UE selects both the SR resource n1 to send the SR to the eNodeB and the SR resource n2 to send the SR to the eNodeB, the UE may indicate that n1 is the "preferred" parameter set when selecting the SR resource n1 to send the SR. The UE may simultaneously indicate n2 as a "preferred" parameter set when selecting the SR resource of n2 to transmit the SR.

If n1 has SR resources and n2 has no SR resources, the UE may simultaneously indicate n1 as a "preferred" parameter set when selecting the SR resource of n1 to send an SR to the eNodeB. In addition, n2 may also be indicated as an "optional" parameter set.

If n2 has SR resources and n1 has no SR resources, the UE may indicate n2 as an "optional" parameter set when selecting the SR resource of n2 to send an SR to the eNodeB. At the same time, n1 may also be indicated as a "preferred" parameter set.

If neither n1 nor n2 has SR resources, and n3 or other parameter groups have SR resources, the UE may select SR resources corresponding to one parameter group to send an SR according to a priority selection or a random selection. Meanwhile, the UE may also indicate a priority corresponding to the selected parameter set. For example, if the UE selects the SR resource of n3 to transmit the SR, it may also indicate n3 as "unavailable" parameter set.

In the method provided by the embodiment of the present invention, after the SR is triggered, for any two types of services, when data arrives in the cache of the logical channel corresponding to the first type of service, based on SR resources corresponding to the first type of service and the second type of service, an SR is sent to an eNodeB. For any parameter set in the first parameter set and the second parameter set, priority information corresponding to the parameter set is determined. And sending priority information corresponding to any parameter group to the eNodeB. As the available SR resources can be mutually selected to send the SR among different types of services according to the requirements, the utilization rate of the SR resources is improved.

In addition, when the SR is sent, the priority corresponding to the parameter group can be also indicated, so that a basis is provided for the system to subsequently configure the parameter group for the UE.

Finally, when no SR resource exists in the parameter group, the uplink resource can be applied through the random access process, that is, the PRACH resource configured correspondingly to the parameter group is correspondingly selected according to the priority of the logical channel mapping to perform the random access process, thereby improving the success rate of the uplink resource application.

Please refer to fig. 5, which illustrates a schematic structural diagram of an uplink scheduling request processing device according to an embodiment of the present invention, where the device may be configured to implement the uplink scheduling request processing method provided in the foregoing embodiment, and the device may correspond to a UE. Specifically, the method comprises the following steps:

the device 500 may include RF (Radio Frequency) circuitry 110, memory 120 including one or more computer-readable storage media, input unit 130, display unit 140, sensor 150, audio circuitry 160, WiFi (Wireless Fidelity) module 170, processor 180 including one or more processing cores, and power supply 190. Those skilled in the art will appreciate that the configuration of the apparatus shown in fig. 5 is not intended to be limiting of the apparatus and may include more or fewer components than those shown, or some components may be combined, or a different arrangement of components. Wherein:

the RF circuit 110 may be used for receiving and transmitting signals during information transmission and reception or during a call, and in particular, receives downlink information from a base station and then sends the received downlink information to the one or more processors 180 for processing; in addition, data relating to uplink is transmitted to the base station. In general, the RF circuitry 110 includes, but is not limited to, an antenna, at least one Amplifier, a tuner, one or more oscillators, a Subscriber Identity Module (SIM) card, a transceiver, a coupler, an LNA (Low Noise Amplifier), a duplexer, and the like. In addition, the RF circuitry 110 may also communicate with networks and other devices via wireless communications. The wireless communication may use any communication standard or protocol, including but not limited to GSM (Global System for Mobile communications), GPRS (General Packet Radio Service), CDMA (Code Division Multiple Access), WCDMA (Wideband Code Division Multiple Access), LTE (Long Term Evolution), email, SMS (short messaging Service), etc.

The memory 120 may be used to store software programs and modules, and the processor 180 executes various functional applications and data processing by operating the software programs and modules stored in the memory 120. The memory 120 may mainly include a storage program area and a storage data area, wherein the storage program area may store an operating system, an application program required by at least one function (such as a sound playing function, an image playing function, etc.), and the like; the stored data area may store data (such as audio data, a phonebook, etc.) created according to the use of the device 500, and the like. Further, the memory 120 may include high speed random access memory, and may also include non-volatile memory, such as at least one magnetic disk storage device, flash memory device, or other volatile solid state storage device. Accordingly, the memory 120 may further include a memory controller to provide the processor 180 and the input unit 130 with access to the memory 120.

The input unit 130 may be used to receive input numeric or character information and generate keyboard, mouse, joystick, optical or trackball signal inputs related to user settings and function control. In particular, the input unit 130 may include a touch-sensitive surface 131 as well as other input devices 132. The touch-sensitive surface 131, also referred to as a touch display screen or a touch pad, may collect touch operations by a user on or near the touch-sensitive surface 131 (e.g., operations by a user on or near the touch-sensitive surface 131 using a finger, a stylus, or any other suitable object or attachment), and drive the corresponding connection device according to a predetermined program. Alternatively, the touch sensitive surface 131 may comprise two parts, a touch detection means and a touch controller. The touch detection device detects the touch direction of a user, detects a signal brought by touch operation and transmits the signal to the touch controller; the touch controller receives touch information from the touch sensing device, converts the touch information into touch point coordinates, sends the touch point coordinates to the processor 180, and can receive and execute commands sent by the processor 180. Additionally, the touch-sensitive surface 131 may be implemented using various types of resistive, capacitive, infrared, and surface acoustic waves. In addition to the touch-sensitive surface 131, the input unit 130 may also include other input devices 132.

The Display unit 140 may include a Display panel 141, and optionally, the Display panel 141 may be configured in the form of an LCD (Liquid Crystal Display), an OLED (Organic Light-Emitting Diode), or the like. Further, the touch-sensitive surface 131 may cover the display panel 141, and when a touch operation is detected on or near the touch-sensitive surface 131, the touch operation is transmitted to the processor 180 to determine the type of the touch event, and then the processor 180 provides a corresponding visual output on the display panel 141 according to the type of the touch event.
