Description

一种传输资源请求的方法和装置 技术领域
本发明的实施例涉及通信系统,尤其是涉及一种传输资源请求的方法和装置。
背景技术
长期演进(Long Term Evolution,LTE)系统中,演进基站(Evolved NodeB,eNodeB)负责调度用户设备(User Equipment,UE)的下行数据和上行数据,并在空口上进行传输,而对于UE的上行数据,由于UE先产生上行数据,eNodeB需要获得该UE的上行数据信息(如数据量的大小),才能为该UE分配合适的用于发送该上行数据的传输资源,从而进行及时、准确地调度。
具体的,如图1所示,UE1请求上行数据的传输资源流程如下:
101、当UE1中产生需要向UE2发送的上行数据,且UE1并不存在发送该上行数据的传输资源时,UE1向eNodeB发送调度请求(Scheduling Request,SR),通知eNodeB为UE1分配发送上行数据的传输资源(1.5ms)。
102、eNodeB为UE1分配上行授权资源(UL Grant),并向UE1发送该UL Grant,该UL Grant用于UE1将自身缓存的上行数据的数据量信息报告给eNodeB(4ms)。
103、UE1收到eNodeB分配的该UL grant后,UE1在该UL grant对应的传输资源上,向eNodeB发送缓存状态报告(Data Radio Bearer,BSR)(4ms)。
104、eNodeB根据接收到的BSR为该UE1分配发送上行数据的传输资源和调度控制资源,其中,所述调度控制资源用于在UE1使用所分配的上行数据传输资源发送上行数据时,发送调度指派(Scheduling Assignment,SA),eNodeB发送资源调度信息通知UE1传输资源信息和调度控制资源信息(4ms)。
105、UE1在该传输资源上向UE2上行数据,在该调度控制资源上向UE2发送SA,其中,该SA用于通知UE2该上行数据发送的传输格式信息与数据的传输资源位置信息(4ms)。
由于UE1和UE2之间频繁通信,如果仍然采用图1所示的调度方式,UE1与eNodeB频繁通信,则会造成eNodeB与UE之间传输资源开销过大,并且UE1向eNodeB请求上行数据传输资源需要17.5ms,传输时延过长,无法满足UE1与UE2通信的低时延需求(10ms)。

具体实施方式
下面将结合本发明实施例中的附图,对本发明实施例中的技术方案进 行清楚、完整地描述,显然,所描述的实施例是本发明的一部分实施例,而不是全部实施例。基于本发明中的实施例,本领域普通技术人员在没有做出创造性劳动的前提下所获得的所有其他实施例,都应属于本发明保护的范围。
在图1所示的请求上行数据传输资源的方法中,应理解,调度请求SR是使用物理上行控制信道(physical uplink control channel,PUCCH)来发送的,所使用的格式是format 1,只表示UE有数据传输,并没有携带任何更多的其他辅助信息。
还应理解,BSR上报时,为了减少BSR本身占用的传输资源开销,可以以逻辑信道(Logical Channel,LCH)或逻辑信道组(Logical Channel Group,LCG)为单位进行上报,一个LCG可以包括至少两个逻辑信道(Logical Channel,LCH),即UE上报的数据量至少两个逻辑信道(Logical Channel,LCH)的总量,eNodeB收到BSR后并不知道每个LCH的准确数量,并且,通常不同的LCH具有不同的优先级,eNodeB仅通过BSR是不能准确判断不同优先级的数据量信息,因此,在调度时,eNodeB无法进行准确的参考,从而影响调度的性能。
图2示出了本发明实施例的一种应用场景的网络结构示意图,如图2所示,该通信系统中至少包括两个UE和一个eNodeB,其中UE与eNodeB之间通过Uu口通信,UE与UE之间通过Uv口通信。
具体而言,在车辆通信的场景中,车辆通信消息频繁,如图1所示,每100至300米就会发送一个车辆通信消息,在车辆较多情况下,比如:200辆车,大概每1ms就有两辆车需要发送安全消息,如果采用上述调度方式,Uu接口开销较大,而且部分车辆通信消息要求传输的时延要低于10ms,而上述资源请求的时延在17.5ms左右,不满足低时延要求的车辆通信需求。
应理解,本发明中提到的基站,可以是长期演进(Long Term Evolution,LTE)系统的基站,即eNodeB,也可以是通用移动通讯系统(Universal Mobile Telecommunications System,UMTS)系统的基站,还可以其它系统的基站,本发明实施例以eNodeB为例进行说明,但是这仅是本发明举的例子,本发明包括并不限于此。
还应理解,本发明中的UE可以为手机,智能终端,多媒体设备,流媒体设备或车辆等等,为了描述方便,本发明实施中统称为UE,但本发明包括并不限于此。

1203、UE1根据所述D2D PSRCH资源配置信息向所述eNodeB发送确定的D2D传输资源指示。
具体而言,UE1上有D2D数据到达后,在满足一定条件时会触发D2D BSR,如果UE1不存在发送D2D BSR的上行传输资源,则会触发D2D SR,如果UE1存在发送D2D SR的传输资源,则在对应的D2D SR传输资源上向eNodeB发送D2D SR,该D2D SR的发送代表UE1缓存了上行数据,且触发了D2D BSR,需要eNodeB分配D2D传输资源用于发送该上行数据。
其中,所述D2D SR用于向基站请求D2D传输资源,所述D2D传输资源用于UE1向UE2发送数据。
其中,D2D PSRCH资源配置信息包括下述至少一项:
—PSRCH的时频资源位置信息,具体可以包括PSRCH子帧位置、PSRCH的物理资源块位置、PSRCH的资源配置周期和配置周期内的资源偏移量等至少一种。

—PSRCH的配置周期、配置周期内的子帧偏移和子载波位置信息。
—PSRCH的配置周期、配置周期内的子帧偏移和物理资源块位置信息。
需要特别说明的是,上述列举的D2D PSRCH资源配置信息仅是本发明实施例所举的例子,本发明中的D2D PSRCH资源配置信息包括并不限于上述表述。
1204、eNodeB接收到所述D2D传输资源指示后,根据所述D2D传输资源指示为所述UE1分配传输资源。
具体的,所述eNodeB根据所述D2D传输资源指示为所述UE1分配传输资源具体采用下述任一方式:
方式二,如果所述D2D传输资源指示用于为该D2D传输资源指示对应的传输接口请求传输资源,则所述eNodeB为所述UE1分配特定传输接口资源。
具体的,可以参见表1,通过对不同D2D传输资源指示确定UE1需要传输数据的接口。
方式三,如果所述D2D传输资源指示用于标识数据量的大小,则所述eNodeB根据所述D2D传输资源指示标识的数据量为所述UE1分配传输资源。
例如,表2中,如果eNodeB接收的D2D传输资源指示为01,则指示UE缓存的数据量的范围为100~200字节,eNodeB可以为所述UE1分配不低于100字节、且不高于200字节的D2D传输资源给UE1。
如果eNodeB分配的D2D传输资源不足以传输全部D2D数据,则UE仅按照eNodeB所分配的D2D传输资源所能容纳的数据量大小传输D2D数据。
方式四,如果所述D2D传输资源指示用于标识缓存消息的类型,则所述eNodeB根据所述D2D传输资源指示所标识缓存消息的类型为所述UE1分配传输资源。
具体的,可以参见表2,通过D2D传输资源指示标识缓存消息的类型为所述UE1分配所述消息的类型所对应的传输资源,例如,如果D2D传输资源指示为00,则表示当前待发送的消息为V2V CAM(Cooperative Awareness Message,协作感知消息)中的High Frequency Message消息,而发送V2V CAM中的High Frequency Message消息的传输资源范围在100~150字节,则eNodeB可以根据该V2V CAM中的High Frequency Message消息的类型为所述UE1分配可以传输大于等于150字节数据的传输资源。
又如,如表3所示,如果当前D2D传输资源指示为01,则表示当前待发送的消息为V2V CAM中的Low Frequency Message,通常发送V2V CAM中的Low Frequency Message消息需要500~700字节的传输资源,则eNodeB可以根据该V2V CAM中的Low Frequency Message消息为UE1分配700字节的传输资源。
方式五,如果所述D2D传输资源指示用于标识需要发送消息的优先级, 则所述eNodeB根据所述D2D传输资源指示所标识的优先级为所述UE1分配传输资源。
具体的,可以参见表4,通过所述D2D传输资源指示标识的发送消息的优先级为所述UE分配传输资源,如当D2D传输资源指示为00时,则表示当前待发送消息的优先级最高,则eNodeB可以根据该D2D传输资源指示优先为该UE1分配传输资源。
方式六,如果所述D2D传输资源指示用于标识需要额外请求的资源量,则所述eNodeB根据所述D2D传输资源指示所标识的额外请求资源量的大小为UE1分配传输资源。
需要特别说明的是,eNodeB可以为UE1配置半静态资源,对于所述UE1来说,可以周期性的使用半静态配置的资源,但是数据包的大小是可变的,因此UE1需要发送数据包的大小并不固定,就会出现半静态资源不足以发送缓存数据的情况,因此,在这种情况下,可以采用方式六来分配传输资源。
具体的,可以参见表5,通过D2D传输资源指示为所述UE1分配所述额外请求资源量,例如,当所述D2D传输资源指示为00时,用于指示所述额外请求的资源量为100字节,则所述eNodeB可以为所述UE1分配100字节的传输资源。
方式七,如果所述D2D传输资源指示用于标识业务的类型,则所述eNodeB根据D2D传输资源指示所标识业务类型为所述UE1分配传输资源。
具体的,可以参见表6,通过不同D2D传输资源指示为所述UE1分配所述业务类型所对应的传输资源,如,当D2D传输资源为00时,则表示当前待发送业务为安全业务,则eNodeB可以根据该D2D传输资源指示的业务类型为该UE1分配传输资源。
需要特别说明的是,上述D2D传输资源指示可以由基站为用户设备配置,也可以能通过系统广播通知,也可以预先配置在用户设备中,这些配 置方式仅是本发明所举的例子,本发明包括并不限于此,只要能获知D2D传输资源指示所代表的内容都属于本发明的保护范围,在此不再赘述。
1205、eNodeB向所述UE1发送D2D数据传输资源调度信息。
可选的,该调度信息中还可以包含UE1向UE2发送D2D数据的调度控制信息的资源。
1206、所述UE1向所述UE2发送数据。
可选的,所述UE1向所述UE2发送传输数据的调度控制信息。
基于上述技术方案,本发明实施例提供了一种传输资源请求方法,第一UE通过确定需要发送的设备到设备D2D传输资源指示,并向eNodeB发送所述所述D2D传输资源指示,所述D2D传输资源指示用于请求所述eNodeB为所述第一UE分配D2D传输资源,以使得所述eNodeB根据接收到D2D传输资源指示为UE分配传输资源,省略了现有技术中eNodeB需要向第一UE发送上行授权,第一UE再向eNodeB发送上BSR的流程,进而节省了eNodeB与UE之间传输资源开销,也避免第一UE向eNodeB请求传输资源过长的问题,降低调度时延。
图13示出了根据本发明实施例另一种传输资源请求方法的示意性流程图,包括:
首先,需要特别说明的,D2eNodeB传输资源是指UE与基站进行数据传输时所需的资源。
1301、eNodeB为UE1配置需要传输的D2D消息类型与D2D传输资源指示的对应关系。

表7
1302、eNodeB向UE1发送D2D PSRCH资源配置信息,所述D2D PSRCH资源配置信息中包含D2D消息类型与D2D传输资源指示的对应关系。
1303、当UE1中产生低时延消息或紧急的D2D消息,UE触发D2D BSR和D2D SR,UE1在D2D PSRCH传输资源上发送D2D传输资源指示,其中当D2D传输资源指示为0时,执行流程一;或者,当UE1中产生非低时延或非紧急的D2D消息,UE触发D2D BSR和D2D SR,UE1在D2D SR传输资源上发送D2D SR信息,其中D2D传输资源指示为1,执行流程二:
具体的,流程一可以包括:
1304、当eNodeB接收到UE1发送的D2D SR,且D2D传输资源指示为0时,则eNodeB确认所述UE1缓存了低时延消息或紧急消息需要发送,并且需要至少分配300字节D2D传输资源才能够满足所述低时延消息或紧急消息的传输需求。
1305、eNodeB判断当前是否能够为该UE1分配足够的传输资源,用于发送所述低时延消息或紧急消息。
具体的,eNodeB可以根据当前负载情况判断是否能够为所述UE分配足够的传输资源,该传输资源用于发送所述低时延消息或紧急消息。
1306、如果步骤1305的判断结果为是,则eNodeB为UE分配足够发送所述低时延消息或紧急消息的传输资源,eNodeB向UE发送调度资源分配消息,所述调度资源分配消息中指示了分配给该UE的传输资源信息;或者,如果步骤1305的判断结果为否,则eNodeB为该UE分配发送D2D BSR的传输资源,eNodeB发送调度资源分配消息给UE,调度资源分配消息中指示了分配给该UE的D2D BSR的传输资源信息。
具体的,eNodeB将优先于其他业务为该UE1请求分配发送低时延消 息和紧急消息的传输资源。
1307、UE1接收到eNodeB发送的D2eNodeB调度资源分配消息,并获得D2eNodeB调度资源分配消息所指示的D2eNodeB传输资源。
1308、UE1组装向eNodeB发送的MAC PDU时,UE1判断所获取的D2D传输资源是否足够将所述紧急消息或低时延消息发送完成。
1309、如果所述UE1确定在所获取的D2D传输资源足够将所述紧急消息或低时延消息发送完成,则UE取消触发D2D BSR,或者如果所述UE1确定获取的D2D传输资源足够将所述紧急消息或低时延消息发送完成,则所述UE1报告D2D BSR为0值;或者,所述UE确定在当前传输时间间隔内所获得的传输资源不够将所述紧急消息或低时延消息发送完成,则所述UE将紧急消息缓存信息所对应的D2D BSR复用在UE向eNodeB发送的MAC PDU中。
1310、UE1将所述MAC PDU发送给eNodeB。
具体的,如图14所示,流程二包括:
1304a、当eNodeB接收到UE1发送的D2D SR,且D2D传输资源指示为1时,根据UE1需要传输的D2D的消息类型和D2D传输资源指示对应关系,eNodeB判断该UE1当前需要发送D2D非低时延消息或D2D非紧急消息。
1305a、eNodeB为该UE1分配传输资源,该传输资源用于发送D2D BSR。
1306a、eNodeB发送调度资源分配消息给UE1,该调度资源分配消息中指示了分配给UE1的D2eNodeB传输资源信息。
1307a、UE1接收到eNodeB发送的调度资源分配消息,并获得调度资源分配消息所指示的D2eNodeB传输资源。
1308a、UE1组装UE向eNodeB发送的MAC PDU时,UE1判断所获得的D2D传输资源是否能足够将所述非低时延消息或非紧急消息发送,或 所述非低时延消息或非紧急消息是否已经发送完成。
1309a、如果步骤608a的判断结果为是,则UE1取消触发D2D BSR,或报告D2D BSR为0值;或者,如果步骤608a的判断结果为否,则UE1将非低时延消息或非紧急消息缓存数据量对应的D2D BSR复用在该MAC PDU中。
1310a、UE1复用完该MAC PDU后,将该MAC PDU发送给eNodeB。
基于上述技术方案,本发明实施例的一种传输资源请求方法,eNodeB根据D2D传输资源指示为UE1分配传输资源,当传输资源足够的情况下,UE1省略或取消发送D2D BSR,节省了eNodeB与UE之间传输资源开销,也避免E1向eNodeB请求上行数据数据资源传输资源过长的问题,降低调度时延。
本发明实施例的另一种可实现方式,可以参见表9,eNodeB也可以依据逻辑信道与D2D传输资源指示的对应关系,获知UE需要发送消息的紧急程度,具体的,eNodeB可以预先设定逻辑信道优先级与D2D传输资源指示的对应关系,或者通过协议规定逻辑信道组优先级与D2D传输资源指示的对应关系,具体的流程和有益效果可以参照图13所示的实施例,在此不再赘述。
本发明实施例的另一种可实现方式,可以参见图13,eNodeB也可以依据逻辑信道组与D2D传输资源指示的对应关系,获知UE需要发送消息的紧急程度,具体的,eNodeB可以预先设定逻辑信道组优先级与D2D传输资源指示的对应关系,或者通过协议规定逻辑信道组优先级与D2D传输资源指示的对应关系,具体的流程和有益效果可以参照图13所示的实施例,在此不再赘述。
本发明实施例的另一种可实现方式,按照上述配置,在具体实现中不一定要配置多个逻辑信道组或逻辑信道与D2D传输资源指示的对应关系,而是可以配置至少一个逻辑信道组或逻辑信道与D2D传输资源指示的对应 关系,如表11所示:
UE1需要传输的D2D的消息逻辑信道组 D2D传输资源指示
逻辑信道组1(紧急消息300 Bytes) 00
逻辑信道组2(高频消息150 Bytes) 01
逻辑信道组3(低频消息700 Bytes) 10
逻辑信道组4(其他消息) 11
表11
该实施例的具体的流程和有益效果可以参照图13所示的实施例,在此不再赘述。
本发明中所指的D2D BSR既可以是一个UE中所有D2D数据对应的UE BSR,也可以是一个UE中一个逻辑信道组对应的逻辑信道组BSR;还可以是一个UE中一个逻辑信道所对应逻辑信道的BSR,也可以是一个UE中该UE的分组的设备所对应的分组BSR,对此,本发明不做具体的限定。
基于上述技术方案,本发明实施例提供了一种传输资源请求方法,如果所述第一数据传输资源能够容纳全部设备到设备D2D数据,则UE构建不包含D2D缓存状态报告BSR的媒体接入控制协议数据单元MAC PDU,从而UE向eNodeB直接发送MAC PDU,不需要向eNodeB发送D2D BSR,省略了现有技术中eNodeB需要向UE发送上行授权,UE再向eNodeB发送上BSR的流程,进而节省了eNodeB与UE之间传输资源开销,也避免UE向eNodeB请求上行数据数据资源传输资源过长的问题,降低调度时延。
图15示出了根据本发明实施例的一种传输资源请求方法的示意性流程图,该实例包括:
1501、UE1产生需要向UE2发送的数据。
1502、所述UE1向eNodeB发送SR。
1503、当eNodeB收到SR后,eNodeB为UE1分配D2eNodeB传输资源,所述D2eNodeB传输资源用于所述UE1将其缓存的待发送的D2D数据量信息上报给eNodeB。
1504、eNodeB向UE1发送所分配的D2eNodeB传输资源信息。
1505、UE1在D2eNodeB传输资源所对应的上行资源上,向eNodeB发送D2D BSR。
1506、eNodeB根据接收到的D2D BSR为该UE1分配数据传输资源,可选的包含调度控制资源,所述数据传输资源用于UE1向UE2发送数据。
1507、UE1缓存D2eNodeB数据,并且UE1触发发送D2eNodeB BSR。
1508、UE1向eNodeB发送D2eNodeB SR。
1509、eNodeB向UE1发送D2eNodeB UL Grant上行数据传输资源。
1510、UE1向基站发送D2eNodeB BSR和/或D2D BSR。
需要特别说明的是,步骤1510中,是否发送D2D BSR需要根据下述任一规则确定:
规则一,UE1判断当前D2D BSR是否被触发,如果D2D BSR被触发,则确定向eNodeB发送D2D BSR,该D2D BSR用于通知eNodeB需要分配数据D2D传输资源的大小。
其中,D2D BSR中可以指示D2D数据传输资源的大小,进一步,UE1可以通过以下方式获取D2D数据传输资源的大小,如:
当前D2D数据缓存量减去eNodeB已经分配给UE1的D2D所能发送的数据大小。
可选的,D2D BSR中标识D2D数据传输资源的大小可以以D2D设备组为单位,详情如下:
D2D BSR中可以包含多个不同的D2D Group BSR value,不同D2D组的D2D BSR数据可以分别计算,即用某一个组的缓存数据量减去该组使用所能获得的D2D资源所能发送数据量大小。
具体的,eNodeB已经为UE1分配D2D的传输资源可以为100字节,其中:
D2D Group A缓存数据量为70字节;
D2D Group B缓存数据量为50字节;
D2D Group C缓存数据量为40字节;
D2D Group A的优先级高于D2D Group B,D2D Group B的优先级高于D2D Group C,因此,D2D BSR中包含D2D Group A标识D2D数据传输资源的大小为0,D2D Group B BSR中标识D2D数据传输资源的大小为50-(100-70)=20字节,D2D Group C BSR中标识D2D数据传输资源的大小为40字节。
可选的,D2D BSR中标识D2D数据传输资源的大小可以以逻辑信道组为单位,即不同逻辑信道组分别计算,详情如下:
逻辑信道组(Logical Channel Group,LCG)A缓存数据量为70字节;
LCG B缓存数据量为50字节;
LCG C缓存数据量为40字节;
比如,逻辑信道组(Logical Channel Group,LCG)A优先级高于LCGB的优先级,则UE1的D2D BSR中包含LCG A BSR标识D2D数据传输资源的大小为0,LCG B BSR标识D2D数据传输资源大小为50-(100-70)=20字节,LCG C BSR标识D2D数据传输资源大小为40字节。
规则二,UE1判断当前D2D BSR是否被触发,如果D2D BSR已经被触发,并且当前获得的D2D传输资源足够用于传输D2D缓存数据,则UE取消该D2D BSR触发状态。
规则三,UE1判断当前D2D BSR是否被触发,如果D2D BSR已经被触发,并且当前获得的D2D传输资源足够用于传输D2D缓存数据,则UE在本次上行传输中不包含该触发的D2D BSR。
规则四,UE1判断当前D2D BSR是否被触发,如果D2D BSR已经被触发,并且当前获得的D2eNodeB传输资源能够容纳D2eNodeB缓存数据和MAC CE,确不能同时容纳D2eNodeB、其他高优先级MAC CE和D2D BSR,则UE取消该D2D BSR触发状态,其中MAC CE的优先级要高于 D2eNodeB缓存数据。
规则五,UE1判断当前D2D BSR是否被触发,如果D2D BSR已经被触发,并且当前获得的D2eNodeB传输资源能够容纳D2eNodeB缓存数据和MAC CE,确不能同时容纳D2eNodeB、MAC CE和D2D BSR,则UE在本次上行传输中不包含该触发的D2D BSR,其中MAC CE的优先级要高于D2eNodeB缓存数据。
规则六,UE1判断当前D2D BSR是否被触发,如果D2D BSR已经被触发,并且当前获得的D2eNodeB传输资源能够容纳传输D2eNodeB缓存数据和D2D BSR,确不能同时容纳全部D2eNodeB缓存数据、D2D BSR和D2eNodeB BSR,则UE在本次上行传输中不包含该触发的D2eNodeB BSR。
规则七,UE1确定需要发送MAC CE和/或D2eNodeB数据后,如果仍然有剩余的传输资源,该剩余的传输资源如果能够承载D2D BSR信息,此时可以触发Padding D2D BSR.
需要特别说明的是,BSR是在有数据需要发送时才被UE触发,例如,当有D2eNodB数据需要发送的时候触发D2eNodeB BSR,当有D2D数据需要发送时候触发D2D BSR;或者,不论是否有数据需要发送,如果在复用完高优先级的MAC控制单元和D2eNodeB数据后,仍然有空闲资源可以容纳D2D BSR,则触发Padding D2D BSR,在触发Padding D2D BSR后,其报告的方式类以于方式一或方式二,在此不再赘述。
1511、eNodeB根据D2eNodeB BSR为UE1分配D2eNodeB的传输资源;和/或eNodeB根据D2D BSR为UE1分配D2D传输资源。
1512、eNodeB发送D2eNodeB调度信息给UE1通知UE1所分配的D2eNodeB传输资源信息;和/或eNodeB发送D2D调度信息给UE1通知UE1所分配的D2D传输资源信息。
1513、UE1在所分配的D2eNodeB资源上发送D2eNodeB数据给eNodB;和/或UE1在所分配的D2D资源上发送D2D数据给UE2;。
基于上述技术方案,本发明实施例提供了一种传输资源请求方法,UE确定设备到设备D2D缓存状态报告BSR已经被触发,所述UE获取演进基站eNodeB分配的D2eNodeB数据传输资源,所述UE根据D2eNodeB数据传输资源对数据信息的容纳情况确定BSR的处理方式,节省了eNodeB与UE之间传输资源开销,也避免UE向eNodeB请求上行数据数据资源传输资源过长的问题,降低调度时延。
需要特别说明的是D2eNodeB BSR是指UE需要向eNodeB发送的BSR,为了表述方便,本发明实施例中简称为D2eNodeB BSR。D2eNodeB传输资源是指UE需要向eNodeB发送的BSR,为了表述方便,本发明实施例中简称为D2eNodeB传输资源。D2eNodeB SR是指是指UE需要向eNodeB发送的BSR,为了表述方便,本发明实施例中简称为D2eNodeB SR。D2eNodeB UL Grant是指是指UE需要向eNodeB发送的UL Grant,为了表述方便,D2eNodeB UL Grant。
需要特别说明的是,本发明实施例中,非padding BSR可以被称作normal BSR,这类BSR是由缓存中的数据触发的,比如:缓存数据从无到有(数据到达),则会触发Reqular BSR,另外还有periodic BSR,如果缓存中有数据则会周期性触发,regular/periodic BSR都是normal BSR,这类BSR优先级较高,高于数据优先级;而Padding BSR在标准上称作BSR for padding,就是用来填充剩余资源的BSR,如果剩余资源不够、或没有剩余资源,则不会发Padding BSR。
