Description

Uplink scheduling request processing method and device

technical field

The present invention relates to the field of communication technologies, and more particularly, to a method and device for processing an uplink scheduling request.

Background technique

In the LTE (Long Term Evolution, Long Term Evolution) system, when the UE (User Equipment, user equipment) has no service data to send, that is, when there is no need to upload service data to the eNodeB (Evolved Node B, evolved base station), the eNodeB does not There is no need to allocate uplink resources for the UE. Otherwise, uplink resources will be 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 usually needs to inform the eNodeB that it has service data to send, and the eNodeB will accordingly decide whether to allocate uplink resources to the UE. . Among them, the UE in the RRC_CONNECTED state and maintaining the uplink synchronization can notify the eNodeB that it needs uplink resources by sending an SR (Scheduling Request, scheduling request) for sending on the UL-SCH (Uplink-Shared Channel, Uplink Shared Channel) business data. Through the above process, the eNodeB can be informed that there is service data that needs to be sent, but the eNodeB cannot be told how much service data needs to be sent.

Generally, the UE can inform the eNodeB how much service data needs to be sent in its buffer by sending a BSR (Buffer Status Report, buffer status report). The above-mentioned SR sending process has corresponding triggering methods, especially for NR (New Radio, new air interface) systems, such as 5G networks, the SR triggering method affects its service scheduling result, so how to trigger SR and other related processing is a key issue.

In the related art, that is, in the media access control layer protocol of the LTE system, the triggering conditions of the SR are defined as follows: if the UE triggers the BSR for the first time, or triggers the BSR after sending the BSR last time, then if the UE is currently in the current state When TTI (Transmission Time Interval, transmission time interval) is not configured with uplink resources that can be used for the first transmission, and the BSR is a regular BSR, the SR is triggered.

Among them, the conventional BSR can correspond to any of the following triggering conditions: (1) the corresponding buffer of the UE is empty, but there is a new logical channel that has service data to be sent, and the conventional BSR will be triggered at this time; (2) the logical channel corresponding to the UE has services Data needs to be sent, but when service data arrives on the logical channel with higher priority, the regular BSR will be triggered by the logical channel with higher priority; (3) The UE sends an empty BSR, which is mainly used for buffering. synchronization process.

In the process of realizing the present invention, it is found that at least the following problems exist in the related art:

Since there are services with different priorities in the NR system, when a service with a higher priority arrives first, the service with a higher priority will trigger SR, while for a service with a lower priority that arrives later, it will not meet the above-mentioned rules. The BSR cannot be triggered due to the triggering conditions of the BSR, so that the SR will not be triggered, so that the services with lower priority cannot be scheduled in time.

SUMMARY OF THE INVENTION

In the related art, the conventional BSR is triggered according to the triggering condition of the conventional BSR, and after the conventional BSR is triggered, the SR is triggered according to the triggering condition of the SR. For lower-priority services that arrive after higher-priority services, they will not be triggered because they do not meet the triggering conditions of the conventional BSR, so SR will not be triggered, resulting in lower-priority services not being able to be triggered in time. schedule. In order to solve the above problem, embodiments of the present invention provide a method and apparatus for processing an uplink scheduling request that overcomes the above problem or at least partially solves the above problem.

Because for the services with lower priority that arrive later, SR can also be triggered when the UE is not configured with uplink resources, that is, regardless of the priority of the service, multiple SRs can be triggered, thus avoiding the service with lower priority. The SR cannot be triggered if the normal trigger conditions are met, thereby ensuring that the services with lower priority can also be scheduled in time.

Detailed ways

The specific implementations of the embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and embodiments. The following examples are intended to illustrate the present invention, but not to limit the scope of the present invention.

In the LTE system, when the UE has no service data to send, that is, when there is no need to upload service data to the eNodeB, the eNodeB does not need to allocate uplink resources for the UE. Otherwise, uplink resources will be 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 usually needs to inform the eNodeB that it has service data to send, and the eNodeB will accordingly decide whether to allocate uplink resources to the UE. . The UE in the RRC_CONNECTED state and maintaining uplink synchronization can notify the eNodeB that it needs uplink resources for sending service data on the UL-SCH by sending an SR (Scheduling Request, uplink scheduling request). Through the above process, the eNodeB can be informed that there is service data to be sent, but the eNodeB cannot be informed of how much service data needs to be sent. Usually, the UE can inform the eNodeB how much service data needs to be sent in its buffer by sending a BSR. The above-mentioned SR sending process usually has a corresponding triggering method, especially for an NR system, such as a 5G network, the SR triggering method affects its service scheduling result, so how to trigger the SR and other related processing is a key issue.

In the related art, that is, in the media access control layer protocol of the LTE system, the triggering conditions of the SR are defined as follows: if the UE triggers the BSR for the first time, or triggers the BSR after sending the BSR last time, then if the UE is currently in the current state When the TTI is not configured with uplink resources available for the first transmission, and the BSR is a regular BSR, the SR is triggered. Among them, the conventional BSR can correspond to any of the following triggering conditions: (1) the corresponding buffer of the UE is empty, but there is a new logical channel that has service data to be sent, and the conventional BSR will be triggered at this time; (2) the logical channel corresponding to the UE has services Data needs to be sent, but when service data arrives on the logical channel with higher priority, the regular BSR will be triggered by the logical channel with higher priority; (3) The UE sends an empty BSR, which is mainly used for buffering. synchronization process.

Since there are services with different priorities in the NR system, when a service with a higher priority arrives first, the service with a higher priority will trigger SR, while for a service with a lower priority that arrives later, it will not meet the above-mentioned rules. The BSR cannot be triggered due to the triggering conditions of the BSR, so that the SR will not be triggered, so that the services with lower priority cannot be scheduled in time.

In view of the problems in the related art, an embodiment of the present invention provides a method for processing an uplink scheduling request, and the method can be used for a UE. Before describing the contents of the embodiments of the present invention and subsequent embodiments, concepts that may be involved in the embodiments of the present invention and subsequent embodiments are described here.

SR, the full name of Scheduling Request, is a scheduling request, which is a way for the UE to request resources from the eNodeB for sending data. At present, the scheduling request process of the LTE system mainly includes: the UE in the online state periodically obtains the SR resources allocated by the eNodeB in the uplink resources. When the UE needs to send uplink data, the SR can be triggered first, and the SR is sent to the eNodeB. After receiving the SR, the eNodeB schedules the UE that sends the SR, so that the UE starts to send uplink data.

The SR belongs to the information of the physical layer. The action of the UE sending the SR does not require RB (Resouce Block, resource block) resources, and can be sent through the PUCCH (Physical Uplink Control CHannel, Physical Uplink Control Channel). After the eNodeB successfully decodes the SR signal of a certain UE, it may allocate RB resources to the UE through DCI0 (DCI0 is Downlink ControlInformation, a format of DCI), but there is no guarantee that the eNodeB will allocate RBs every time. Sometimes, although the UE sends the SR signal, the eNodeB does not decode it. Even sometimes, in order to obtain uplink RB resources, the UE needs to send the SR signal multiple times, that is, retransmit the SR signal multiple times.

UE, the full name of User Equipment, that is, user equipment, is an important concept in mobile communication. In a wireless communication network, a user terminal is called UE.

eNodeB Evolved Node B, the evolved Node B referred to as eNB, is the name of the base station in LTE. Compared with the existing Node B in 3G, it integrates some RNC functions, reducing the level of protocols during communication.

eNodeB, the full name of Evolved Node B, is the evolved Node B. eNB for short, the name of the base station in LTE. The functions of the eNB include: RRM (Radio Resource Management, Radio Resource Management) function; IP header compression and user data stream encryption; MME (Mobility Management Entity, network node) selection when the UE is attached; Paging information scheduling and transmission; Broadcast information scheduling transmissions; and setting and providing eNB measurements, etc.

Logical channel, the MAC provides data transmission services for the upper layer through the logical channel. Logical channels can generally be divided into two categories: control channels and traffic channels. The control channel is used to transmit control plane information, while the traffic channel is used to transmit user plane information.

Among them, the control channel includes:

Broadcast Control Channel: A downlink channel that broadcasts system control information.

Paging Control Channel: A downlink channel that transmits paging information.

Dedicated Control Channel: A point-to-point bidirectional channel for transmitting dedicated control information, which is established when the UE has an RRC connection.

Common Control Channel: A bidirectional channel for sending control information between the network and the UE before the RRC connection is established.

Multicast Control Channel: A point-to-multipoint downlink channel is used to manage system scheduling and control information transmission from the network to the UE's model base.

Among them, the business channel includes:

Dedicated traffic channel: Dedicated traffic channel is a point-to-point channel dedicated to a UE for transmitting user information. This channel exists in both uplink and downlink.

Multicast Traffic Channel: Point-to-multipoint downlink.

BSR, the full name of Buffer Status Report, is the buffer status report. The eNodeB allocates downlink or uplink radio resources to each UE according to the downlink buffered data in the eNodeB and the BSR received from the UE, respectively.

TTI, the full name of Transmission Time Interval, is the transmission time interval. TTI is a parameter in Universal Mobile Communication System, which refers to the length of an independently decoded transmission in the wireless link. Among them, 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 to this, the state RRC_IDLE is also included.

For 5G networks, ITU-R defines three major application scenarios for 5G in the future, namely enhanced mobile Internet service eMBB (Enhanced Mobile Broadband), massively connected IoT service mMTC (Massive Machine Type Communication) and ultra-high reliability and Ultra-low latency service uRLLC (Ultra Reliable & Low Latency Communication). For the above three types of application scenarios, the capability requirements for 5G networks are defined from eight dimensions, including throughput rate, delay, connection density, and spectral efficiency improvement.

Based on the content of the above definition, referring to FIG. 1 , the method for processing an uplink scheduling request provided by an embodiment of the present invention includes: 101. For any service corresponding to any logical channel, when service data of any service reaches any logical channel, Determine whether the UE has been configured with uplink resources; 102. When the UE is not configured with uplink resources, trigger SR based on any service; 103. When the UE has been configured with uplink resources, if any service is a designated service, the regular BSR is in Triggered when the service data of the specified service arrives and the configuration period of the uplink resource is greater than the preset threshold, the SR is triggered based on the specified service.

In the method provided by the embodiment of the present invention, 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 uplink resources. When the UE is not configured with uplink resources, SR is triggered based on any service. Because for the services with lower priority that arrive later, SR can also be triggered when the UE is not configured with uplink resources, that is, regardless of the priority of the service, multiple SRs can be triggered, thus avoiding the service with lower priority. The SR cannot be triggered if the normal trigger conditions are met, thereby ensuring that the services with lower priority can also be scheduled in time.

In addition, when the UE has been configured with uplink resources, if any service is a designated service, the regular BSR is triggered when the service data of the designated service arrives, and the configuration period of the uplink resources is greater than the preset threshold, the SR is triggered based on the designated service. . Because when the service data corresponding to the designated service arrives, the designated service can be triggered by the SR in time according to the above triggering mechanism, so that the designated service with high reliability and ultra-low delay can be responded to in time.

As an optional embodiment, the method further includes:

After the SR is triggered, for any two types of services, when service data arrives in the logical channel corresponding to the first type of service, the SR is sent to the eNodeB through the SR resources corresponding to the first type of service and the second type of service.

All the above-mentioned optional technical solutions can be combined arbitrarily to form optional embodiments of the present invention, which will not be repeated here.

Based on the content in the foregoing embodiments, the embodiments of the present invention provide a method for processing an uplink scheduling request, and the method can be used for a UE. Referring to FIG. 2, the method includes: 201. For any service corresponding to any logical channel, when service data of any service arrives at any logical channel, determine whether the UE has been configured with uplink resources; 202. When the UE is not When configuring uplink resources, trigger SR based on any service; 203. When the UE has been configured with uplink resources, if any service is a designated service, the regular BSR is triggered when the service data of the designated service arrives, and the configuration of uplink resources If the period is greater than the preset threshold, the SR is triggered based on the specified service; 204. After triggering the SR, for any two types of services, when service data arrives in the cache of the logical channel corresponding to the first type of service, pass the first type of service and the second type of service. The SR resource corresponding to the second type of service sends an SR to the eNodeB based on the first type of service.

Wherein, in step 201, for any service corresponding to any logical channel, when service data of any service reaches any logical channel, determine whether the UE has been configured with uplink resources.

The process for the UE to apply for uplink resources is mainly as follows: The UE inserts a BSR control unit in the packet data unit of the MAC layer to inform the eNodeB that some data needs to be sent in one or several logical channel groups of the UE, so as to apply for some data to the eNodeB. RB resources. In this way, by sending the BSR control unit, the eNodeB can know the amount of data that the UE needs to send, and the eNodeB can allocate RB resources in a targeted manner.

However, since the action of the UE sending the BSR control unit itself also requires uplink RB resources, if the UE does not have any uplink RB resources, it will cause the BSR to be unable to be sent. At this time, the UE may send a resource application to the eNodeB in the following manner. By sending an SR to the eNodeB, when the UE cannot send a BSR to apply for RB resources, it can apply for resources by sending an SR. Since the BSR is encapsulated in the MAC PDU and sent to the eNodeB through the PUSCH channel, uplink RB resources are required. The SR signal can be transmitted in the PUCCH control channel, and an application for resources can be sent to the eNodeB without uplink RB resources. However, since the eNodeB only receives an SR signal, it does not know how many bytes of data the UE needs to upload next, so it is unclear how many resources to allocate are appropriate. Therefore, the subsequent UE may still need to send a BSR to apply for more uplink resources. After the eNodeB receives the SR request from the UE, how many RB resources are allocated is determined by the algorithm of the equipment manufacturer. Generally speaking, after the eNodeB receives the SR signal, the allocated RB resources can at least satisfy the transmission of the BSR.

Of course, in addition to the above two methods of applying for uplink RB resources, there are other application methods. When the UE does not acquire the RB resources allocated by the eNodeB, it may be determined that the UE is not configured with uplink resources. On the contrary, it is determined that the UE has been configured with uplink resources.

Wherein, in step 202, when the UE is not configured with uplink resources, trigger the SR based on any service.

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

About the sr-ProhibitTimer timer: The sr-ProhibitTimer timer is used to monitor the SR signal transmitted in the PUCCH. When the timer is running, the SR cannot be sent. When the timer expires, the UE needs to retransmit the SR until the maximum number of transmissions dsr-TransMax is reached. The value of the sr-ProhibitTimer timer is configured by the RRC and delivered to the UE in the MAC-MainConfig information element.

Wherein, in step 203, when the UE has been configured with uplink resources, if any service is a designated service, the conventional BSR is triggered when the service data of the designated service arrives, and the configuration period of the uplink resources is greater than a preset threshold, then based on the designated service The service triggers the SR.

The above step 202 is mainly a process of triggering SR when the UE is not configured with uplink resources. It can be seen from the content of the foregoing embodiment that the uRLLC service corresponds to an application scenario of ultra-high reliability and ultra-low latency. For the NR system, since the uRLLC service is not divided in the previous LTE protocol, when the uplink resources are configured for services such as VoLTE, it will hinder the triggering of the SR corresponding to the uRLLC service. This will increase the delay of the uRLLC service and even cause packet loss, which contradicts the applicable application scenarios of the uRLLC service. It can be seen from the above description that when the UE has been configured with uplink resources, it still needs to trigger SR for some designated services. Correspondingly, the embodiment of the present invention also provides a method for triggering an SR for a specified service, that is, the content in this step. In addition, this step is performed when the UE has been configured with uplink resources, and the above-mentioned step 202 is performed when the UE is not configured with uplink resources, and the two are branch steps in different situations.

It should be noted that the uRLLC service in the above process may be a type of designated service, and the designated service may correspond to an application scenario of high reliability and ultra-low delay. Through the above process, it can be ensured that the specified service can be triggered by SR in time. Wherein, when judging whether the configuration period of the uplink resources is greater than the preset threshold, the preset threshold in this embodiment of the present invention may be pre-configured by the eNodeB, or may be pre-specified by a communication protocol, which is not specifically limited in this embodiment of the present invention.

For the processing procedure of the uplink scheduling request, in addition to the above-mentioned triggering SR procedure, an SR may also be sent, 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 present invention also provides a method for sending an uplink scheduling request, and the specific process is detailed in the subsequent steps.

In step 204, after triggering SR, for any two types of services, when service data arrives in the cache of the logical channel corresponding to the first type of service, use the SR resources corresponding to the first type of service and the second type of service, based on the first type of service. One type of service sends an SR to the eNodeB.

This step is mainly a process in which the UE selects SR resources to send the SR after the SR is triggered. It should be noted that, in this embodiment of the present invention and subsequent embodiments, after SR is triggered according to the SR triggering mode provided in the above-mentioned embodiment, the SR may be sent by the SR resource sending mode provided in this embodiment and subsequent embodiments. Of course, the process of sending SR resources provided in this embodiment and subsequent embodiments may also be executed after other processes for triggering SR are executed, that is, the process of triggering SR and the process of sending SR provided by this embodiment and subsequent embodiments can be separated and independent implement. In order to describe the process of sending the SR resource by the UE in detail, the process of sending the SR resource by the UE in this step can be found in the content of the subsequent embodiments, which will not be described here.

In the method provided by the embodiment of the present invention, 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 uplink resources. When the UE is not configured with uplink resources, SR is triggered based on any service. Because for the services with lower priority that arrive later, SR can also be triggered when the UE is not configured with uplink resources, that is, regardless of the priority of the service, multiple SRs can be triggered, thus avoiding the service with lower priority. The SR cannot be triggered if the normal trigger conditions are met, thereby ensuring that the services with lower priority can also be scheduled in time.

In addition, when the UE has been configured with uplink resources, if any service is a designated service, the regular BSR is triggered when the service data of the designated service arrives, and the configuration period of the uplink resources is greater than the preset threshold, the SR is triggered based on the designated service. . Because when the service data corresponding to the designated service arrives, the designated service can be triggered by the SR in time according to the above triggering mechanism, so that the designated service with high reliability and ultra-low delay can be responded to in time.

All the above-mentioned optional technical solutions can be combined arbitrarily to form optional embodiments of the present invention, which will not be repeated here.

Based on the content in the foregoing embodiments, the embodiments of the present invention provide a method for processing an uplink scheduling request, and the method can be used for a UE. Referring to FIG. 3, the method includes: 301. After triggering the SR, for any two types of services, when service data arrives in the logical channel corresponding to the first type of service, use the SR resources corresponding to the first type of service and the second type of service. 302, for any parameter group in the first parameter set and the second parameter set, determine the priority information corresponding to any parameter group; 303, send the priority information corresponding to any parameter group to the eNodeB.

Wherein, in step 301, after the SR is triggered, for any two types of services, when service data arrives in the logical channel corresponding to the first type of service, the SR is sent to the eNodeB through the 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 resource or an organization of several resources in the time domain, frequency domain, code domain, and space domain, and the embodiment of the present invention does not specifically limit the type of SR resource. For example, the SR resource may be periodic, occurring every n subframes. The period of the SR can be configured through the sr-ConfigIndex field of IE:SchedulingRequestConfig.

In this step, the priority of the first type of service is higher than that of the second type of service. The embodiments of the present invention do not specifically limit the types of the first type of service and the second type of service. For example, the first type of service may include uRLLC service, and the second type of service may include 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 among all the services supported by the NR system. In addition to the uRLLC service, the first type of service may also include other services with the same priority as the uRLLC service. In addition to the eMBB service with a lower priority than the uRLLC service, the second type of service may also include other services with a priority equivalent to the eMBB service. This step is mainly to illustrate that in addition to sending the SR to the eNodeB through the SR resource corresponding to the first type of service, the SR can also be sent 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 an SR, the SR can also be sent to the eNodeB through the SR resource corresponding to the third type of service. Through the SR resources of the first type of business and the second type of business. That is, "first category" and "second category" are only used to distinguish different types of services. Specifically, in the actual implementation process, if the first type of service needs to send SR, the SR can be sent to the eNodeB through SR resources of other types of services, that is, in addition to the second type of service, the third type of service, The SR resources corresponding to the fourth type of service and other types of services are 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 SR resource needs to be used. Correspondingly, the embodiment of the present invention does not specifically limit the manner 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 the applicable logical channel corresponding to the first type of service. The first parameter set is to determine the second parameter set applicable to the logical channel corresponding to the 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; wherein, the SR The resource state is any one of the following two states, including having SR resources and not having SR resources.

Wherein, the first parameter set includes at least one first parameter group, and the second parameter set includes at least one second parameter group. It should be noted that "first" and "second" are only used to distinguish parameter sets or parameter groups applicable to different logical channels, and do not limit the specific content of the parameter sets or parameter groups. In addition, the parameter group may be represented by "numerology/TTItype", and a logical channel may have multiple applicable "numerology/TTI type", that is, corresponding to multiple parameter groups. The embodiment of the present invention does not specifically limit the number of the first parameter group in the first parameter set, nor does it specifically limit the number of the second parameter group in the second parameter set. "Numerology" refers to the set of communication system parameters. The "numerology" may include subcarrier spacing, symbol length, cyclic prefix length, etc., which is equivalent to a data transmission strategy. For example, the first parameter set may include two "numerology/TTI types", which may be abbreviated as n1 and n2 respectively.

Compared with OFDM under 4G, F-OFDM under 5G benefits from the flexibility of numerology and has greater advantages. Specifically, the design of the basic waveform of the 5G network is the basis for realizing a unified air interface, while taking into account flexibility and spectrum utilization efficiency. For OFDM under 4G, OFDM modulates high-rate data onto mutually orthogonal sub-carriers through serial/parallel conversion, and introduces a cyclic prefix, which better solves the problem of inter-symbol crosstalk. But the main problem with OFDM is its inflexibility. For the future, different applications have different requirements for air interface technology. For example, the Internet of Vehicles service with millisecond-level delay requires extremely short time-domain Symbol and TTI, which requires a wide sub-carrier spacing in the frequency domain. In the multi-connection scenario, the amount of data transmitted by a single sensor is extremely low, but the requirements for the overall number of connections in the system are very high, which requires a relatively narrow subcarrier spacing in the frequency domain. In the time domain, the lengths of Symbol and TTI can be long enough, and there is almost no need to consider the problem of inter-symbol crosstalk, so there is no need to introduce CP. At the same time, asynchronous operation can also solve the problem of terminal power saving.

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

It can be seen from the above content that providing different numerologies according to business requirements can improve the flexibility of business processing. Correspondingly, when the UE sends the SR based on the parameter set, this 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 the SR resource state corresponding to each first parameter group in the first parameter set, and determining the SR resource state corresponding to each second parameter group in the second parameter set; based on each first parameter group and each second parameter group The SR resource status of the parameter group, and the SR is sent to the eNodeB.

For parameter groups corresponding to different types of services, resources for sending SR may be configured as transmission policies, so that the SR resource status of each parameter group can be determined first in the above process. Among them, some parameter groups may not have SR resources, and some parameter groups may have SR resources. Correspondingly, the SR resource state is any one of the following two states, and the following two states include having SR resources and not having SR resources.

Since the states of the SR resources corresponding to the parameter groups are different, the UE will have a corresponding way of selecting the SR resources. Based on this, this embodiment of the present invention does not specifically limit the manner in which the UE sends an SR to the eNodeB based on the SR resource status of each first parameter group and each second parameter group, including but not limited to: when there is a When the first parameter group of the SR resource is used, the first parameter group with the SR resource is used as the first target parameter group, and the SR is sent to the eNodeB based on all the first target parameter groups.

In the above process, the corresponding number of "all" is one or more, that is, when the SR is sent to the eNodeB, the number of the first target parameter group may be one or multiple, which is not specified in this embodiment of the present invention limited.

For example, taking the first parameter groups included in the first parameter set as n1 and n2 as an example, it can be determined whether n1 and n2 have SR resources respectively. When both the first parameter groups n1 and n2 have SR resources, the UE may use both n1 and n2 as the first target reference group, and send the SR to the eNodeB based on n1 and n2.

After determining the first target parameter group, the UE may send the SR according to the first target parameter group. Correspondingly, when the UE sends the SR according to the first target parameter group, the embodiment of the present invention does not specifically limit the manner in which the UE sends the SR to the eNodeB based on all the first target parameter groups, including but not limited to: from all the first target parameter groups At least one first target parameter group is selected from the target parameter group, and an SR is sent to the eNodeB based on the SR resource corresponding to the selected first target parameter group.

For example, it is assumed that the first target parameter groups are n1 and n2 respectively. When sending the SR to the eNodeB, the UE may send the SR to the eNodeB based on the SR resource corresponding to n1, and may also send the SR to the eNodeB based on the SR resource corresponding to n2, that is, choose one of the two. Of course, the UE may also use the SR resources corresponding to n1 and n2 respectively to send the SR to the eNodeB at the same time.

Considering that the first parameter set applicable to the logical channel corresponding to the first type of service may not have a first parameter group with SR resources, the UE may also select the SR resources of the second parameter group in the second parameter set to send SR . Based on this, when the UE sends the SR based on the second parameter set, this 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, including: But not limited to: when the first parameter group with SR resources does not exist in the first parameter set, and the second parameter group with SR resources exists in the second parameter set, the second parameter group with SR resources is used as the second target The parameter group, based on all the second target parameter groups, sends an SR to the eNodeB.

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

After determining the second target parameter group, the UE may send the SR according to the second target parameter group. Correspondingly, when the UE sends the SR according to the second target parameter group, the embodiment of the present invention does not specifically limit the manner in which the UE sends the SR to the eNodeB based on all the second target parameter groups, including but not limited to: from all the second target parameter groups At least one second target parameter group is selected from the target parameter group, and an SR is sent to the eNodeB based on the SR resource corresponding to the selected second target parameter group.

For example, it is assumed that the second target parameter groups are n2 and n3 respectively. When the UE sends the SR to the eNodeB, since it has been previously determined that n1 and n2 do not have SR resources, the UE can select the SR resources corresponding to n3. It should be noted that, when there are other second target parameter groups with SR resources in addition to n3, the UE may also select SR resources corresponding to the other second target parameter groups. In addition, in addition to the second type of service having a lower priority than the first type of service, there may also be other types of services having a lower priority than the first type of service. For these types of services, the UE may also select the SR resources of the target parameter group corresponding to these types of services.

It can be seen from the above content that there may be multiple target parameter groups that can be selected, so when the UE selects the target parameter group, it can be selected by random selection or by priority, which is not made in this embodiment of the present invention. Specific restrictions. The priority may be preset, and the embodiment of the present invention does not specifically limit the setting method.

The above content mainly refers to the SR sending process corresponding to the second parameter group with SR resources in the first parameter set or the second parameter set, and the second parameter group with SR resources may not exist in the second parameter set. At this point, the UE cannot send the SR. In view of the above situation, in order to allow the UE to continue to apply for uplink resources, the embodiment of the present invention further provides a method for the UE to apply for uplink resources through a random access procedure. Correspondingly, the embodiment of the present invention does not specifically limit the manner in which the UE sends an SR to the eNodeB based on the SR resource status of each first parameter group and each second parameter group, including but not limited to: when the first parameter set does not exist When there is a first parameter group with SR resources, and when a second parameter group with SR resources does not exist in the second parameter set, initiate a request to the eNodeB based on the PRACH resources configured corresponding to each first parameter group and each second parameter group random access procedure.

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 data interaction operation between the eNodeB and the UE can be performed normally. The UE can achieve two basic functions through random access:

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

(2) Apply for uplink resources (UL_GRANT).

The above process of sending SR to eNodeB is mainly to apply for uplink resources, and from the functions implemented by the above UE, it can be seen that when the first parameter set does not have the first parameter group with SR resources, and the second parameter set does not have SR resources. When in the second parameter group, the uplink resource can be applied for through the random access procedure.

Since there may be multiple parameter groups correspondingly configured with PRACH resources, the UE may select PRACH resources to initiate a random access procedure to the eNodeB. Correspondingly, 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 resources correspondingly configured for each first parameter group and each second parameter group, Including but not limited to: according to the priority order of each first parameter group and each second parameter group, and sequentially through correspondingly configured PRACH resources, initiate a random access procedure to the eNodeB.

For example, if the parameter sets corresponding to the logical channel to which data arrives are the first parameter set and the second parameter set, the first parameter set in the first parameter set is n1 and n2, and the second parameter set in the second parameter set is n3. The UE may select PRACH resources according to the priority order of random access corresponding to n1, n2 and n3.

Among them, n1, n2 and n3 correspond to the priority order of random access, which can be determined based on the characteristics of the service itself and specific parameters in the numerology. For example, if data arrives in the uRLLC service, based on the characteristics of high reliability and low delay of the uRLLC service, the applicable subcarrier spacing may be 60 Hz. The subcarrier interval corresponding to n1 is 60 Hz, which is consistent with that applicable to the uRLLC service, so the priority is the highest. The subcarrier interval corresponding to n2 is 30HZ, which is slightly different from the uRLLC service, so the priority is second. The subcarrier interval corresponding to n3 is 15HZ, which is far from being applicable to the uRLLC service, so the priority is the lowest.

If the priorities of random access corresponding to n1, n2 and n3 are successively decreased, the UE may first select the PRACH resource corresponding to n1. If n1 has no correspondingly configured PRACH resource, the UE may select the correspondingly configured PRACH resource of n2. If n2 has correspondingly configured PRACH resources, the UE may initiate a random access procedure based on the correspondingly configured PRACH resources of n2. If there is no corresponding PRACH resource configured in n2, the UE may continue to select the PRACH resource correspondingly configured in n3. The above process is repeated until the PRACH resource is selected, and the random access process is completed.

It should be noted that when n1, n2 and n3 do not have correspondingly configured PRACH resources, the UE may also select PRACH resources correspondingly configured in parameter groups corresponding to other logical channels, thereby initiating a random access procedure. Wherein, when the UE selects other logical channels, it may also be selected according to the priority of the logical channels, which is not specifically limited in this embodiment of the present invention.

Since the parameter groups in the first parameter set and the second parameter set are usually configured to the UE by the system, for the parameter groups configured to the UE, some parameter groups (ie, numerology) may be more suitable for the characteristics of the service itself. At this time, the UE can take these parameter groups as the preferred parameter groups of the corresponding service. For some services, the configured parameter group may be relatively inappropriate, so that the UE can use the parameter group as an optional parameter group for the corresponding service. For some services, the configured parameter group may be completely unavailable, so that the UE can use the parameter group as the unavailable parameter group of the corresponding service.

For example, if the subcarrier spacing applicable to the uRLLC service is 60 Hz, and the subcarrier spacing corresponding to n1 is 60 Hz, which is consistent with the applicable uRLLC service, the UE can use n1 as the preferred parameter group. The subcarrier spacing corresponding to n2 is 30 Hz, which is a little different from the uRLLC service, so the UE can use n2 as an optional parameter group. However, the subcarrier interval corresponding to n3 is 15 Hz, which is far from being applicable to the uRLLC service, so the UE can use n3 as an unavailable parameter group.

It can be seen from the above content that different parameter groups may correspond to different degrees of suitability for different services. The suitability of the parameter group may be represented by priority information, which is not specifically limited in this embodiment of the present invention. The priority information may be classified into "preferred", "optional" and "unavailable" according to the above content. Certainly, there may also be other division manners, and the embodiment of the present invention does not specifically limit the division manner of the priority information.

In order to allow the eNodeB to know the suitability of the configuration parameter group for better subsequent configuration, an embodiment of the present invention also provides a method for the UE to indicate the priority of the parameter group to the eNodeB. For details, see subsequent steps. It should be noted that, for the process that the UE indicates the priority of the parameter group to the eNodeB, the process may be performed simultaneously when the SR is sent, or before or after the SR is sent, and may not necessarily be performed according to the sequence of steps described in the embodiments of the present invention.

Wherein, in step 302, for any parameter group in the first parameter set and the second parameter set, determine the priority information corresponding to any parameter group.

For convenience of description, the uRLLC service is taken as an example. For the uRLLC service, there will be a parameter group (ie "numerology/TTI type"), which is more suitable for application scenarios with high reliability and ultra-low latency. For such a parameter group, the UE can take it as a "preferred" parameter group, for example, n1 can be taken as a "preferred" parameter group. For parameter groups that are not suitable for high reliability and ultra-low latency application scenarios, the UE may use such parameter groups as "optional" parameter groups, for example, n2 may be used as "optional" parameter groups. For parameter groups that are not suitable for high reliability and ultra-low latency application scenarios, the UE may regard such parameter groups as "unavailable" parameter groups, for example, n3 may be used as "unavailable" parameter groups. According to the above process, for the system configuration parameter group, the UE can correspondingly determine the priority information corresponding to each parameter group.

Wherein, in step 303, the priority information corresponding to any parameter group is sent to the eNodeB.

After determining the priority information corresponding to each parameter group, the UE may send the priority information corresponding to each parameter group to the eNodeB. It can be known from the content in the above step 301 that the process of indicating the priority of the parameter group to the eNodeB by the UE may be performed when the SR is sent, or before or after. The manner in which the UE sends the priority information corresponding to the parameter group to the eNodeB may be set according to requirements, which is not specifically limited in this embodiment of the present invention. For ease of understanding, the embodiments of the present invention take the UE indicating the priority of the parameter group to the eNodeB as an example to describe the process of the UE sending the priority information corresponding to the parameter group to the eNodeB.

Specifically, when the UE sends the SR to the eNodeB, it is still carried by radio waves. The radio wave usually has a corresponding phase, so when the UE sends the SR, the priority of the parameter group can be indicated by adjusting the phase of the radio wave carrying the SR. Wherein, the priority information may correspond to the phase, or in other words, to the phase angle. As for a specific corresponding manner, this embodiment of the present invention does not specifically limit this. For example, since the waveform cycle is 360 degrees, the phase angle can be divided into 0 degrees, 180 degrees and 360 degrees, respectively corresponding to the three priority information divided in the above content. Among them, 0 degrees can correspond to "preferred", 180 degrees can correspond to "optional", and 360 degrees can correspond to "unavailable".

Combined with the above-mentioned process of the UE selecting SR resources to send the SR, the process of indicating the priority of the parameter group to the eNodeB by the UE is now described as an example. For example, if both parameter groups n1 and n2 have SR resources, and the UE selects both the SR resources of n1 to send SR to the eNodeB, and the SR resources of n2 to send SRs to the eNodeB, the UE selects the SR resources of n1 to send SR to the eNodeB. When sending an SR, it can also indicate that n1 is the "preferred" parameter group. When selecting the SR resource of n2 to send the SR, the UE may simultaneously indicate that n2 is the "preferred" parameter group.

If n1 has SR resources, but n2 does not have SR resources, the UE may simultaneously indicate that n1 is the "preferred" parameter group when selecting the SR resources of n1 to send the SR to the eNodeB. In addition, n2 can also be indicated as an "optional" parameter group at the same time.

If n2 has SR resources, but n1 does not have SR resources, the UE may indicate that n2 is an "optional" parameter group when selecting the SR resources of n2 to send the SR to the eNodeB. At the same time, n1 can also be indicated as the "preferred" parameter group.

If both n1 and n2 do not have SR resources, but n3 or other parameter groups have SR resources, the UE may select SR resources corresponding to a parameter group according to priority selection or random selection to send SR. At the same time, the UE may also indicate the priority corresponding to the selected parameter group. For example, if the UE selects the SR resource of n3 to send the SR, it can also indicate that n3 is the "unavailable" parameter group.

In the method provided by the embodiment of the present invention, after 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, the SR resources corresponding to the first type of service and the second type of service are based on , and send the SR to the eNodeB. For any parameter group in the first parameter set and the second parameter set, determine the priority information corresponding to any parameter group. Send the priority information corresponding to any parameter group to the eNodeB. Since different types of services can select available SR resources to send SRs according to their requirements, the utilization rate of SR resources is improved.

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

Finally, when there is no SR resource in the parameter group, the uplink resource can be applied for through the random access process, that is, the PRACH resource corresponding to the parameter group is correspondingly selected according to the priority of logical channel mapping to perform the random access process, so as to improve the performance of the random access process. The success rate of uplink resource application.

An embodiment of the present invention provides an apparatus for processing an uplink scheduling request. The apparatus can at least execute the uplink scheduling request processing method provided in the embodiments corresponding to FIG. 1 , FIG. 2 , or FIG. 3 , and the apparatus can correspond to a UE. Referring to Figure 4, the device includes:

The determining module 401 is configured to, for any service corresponding to any logical channel, determine whether the UE has been configured with uplink resources when service data of any service reaches any logical channel;

As an optional embodiment, the device further includes:

The sending module is used to send the SR to the eNodeB through the SR resources corresponding to the first type of service and the second type of service for any two types of services after triggering the SR, when service data arrives in the logical channel corresponding to the first type of service .

The apparatus provided by the embodiment of the present invention determines whether the UE has been configured with uplink resources when the service data of any service reaches any logical channel for any service corresponding to any logical channel. When the UE is not configured with uplink resources, SR is triggered based on any service. Because for the services with lower priority that arrive later, SR can also be triggered when the UE is not configured with uplink resources, that is, regardless of the priority of the service, multiple SRs can be triggered, thus avoiding the service with lower priority. The SR cannot be triggered if the normal trigger conditions are met, thereby ensuring that the services with lower priority can also be scheduled in time.

In addition, when the UE has been configured with uplink resources, if any service is a designated service, the regular BSR is triggered when the service data of the designated service arrives, and the configuration period of the uplink resources is greater than the preset threshold, the SR is triggered based on the designated service. . Because when the service data corresponding to the designated service arrives, the designated service can be triggered by the SR in time according to the above triggering mechanism, so that the designated service with high reliability and ultra-low delay can be responded to in time.
