应理解,通信物理特性可以被称为Numerology。该通信物理特性对应通信系统中所采用的不同的参数的集合。不同的Numerology对应的参数可以不同。包括而不限定的,该通信物理特性为以下参数之一或者任意的组合的集合:子载波宽度、循环前缀(Cyclic Prefix,CP)长度、传输时间间隔(Transmission Time Interval,TTI)、符号(Symbol)个数、资源块(Resource Block,RB)位置、时隙长度和帧格式等。作为举例,读者可以从www.3gpp.org获得提案R1-1613779或者R2-168012来理解该通信物理特性Numerology的含义,这些提案的内容包含在本申请的内容中。因为3GPP标准组织的公正性和公开性,这里不再赘述。
不同的Numerology对应的数据可以具有不同的优先级。例如,短的TTI对应的Numerology的优先级高于长的TTI对应的Numerology的优先级。作为示例而非限定的说明,第一Numerology和第二Numerology的比较一般是指相同参数的比较。比如,都是针对TTI的比较,即第一TTI与第二TTI的相关比较。
可选地,作为一种实现方式,在本申请实施例中,该第一数据是属于第一逻辑信道的,第一逻辑信道与第一通信物理特性存在第一映射(Mapping)关系;该第二数据是属于第二逻辑信道的,第二逻辑信道与第二通信物理特性存在第二映射关系;
可选地,作为一种实现方式,第二通信物理特性的优先级高于第一通信物理特性的优先级,该第二逻辑信道的优先级高于该第一逻辑信道的优先级。该第二数据的优先级高于该第一数据的优先级。
可替代地,作为一种实现方式,该第一数据是属于第一逻辑信道组的,该第一逻辑信道组与第一通信物理特性存在第一映射关系,该第二数据是属于第二逻辑信道组的,该第二逻辑信道组与第二通信物理特性存在第二映射关系,第二通信物理特性的优先级高于第一通信物理特性的优先级,该第二逻辑信道组的优先级高于该第一逻辑信道组的优先级。该第二数据的优先级高于该第一数据的优先级。
可选地,作为一种实现方式,该第一映射关系、该第二映射关系是通过信令发送的。例如,终端设备可以通过无线资源控制(Radio Resource Control,RRC)信令接收网络设备发送的该第一映射关系、该第二映射关系。
可选地,在一种实施例中,Numerology与逻辑信道(或者逻辑信道组)具有映射关系,例如,高优先级的Numerology对应高优先级的逻辑信道(或者逻辑信道组),低优先级的Numerology对应低优先级的逻辑信道(或者逻辑信道组)。高优先级的逻辑信道(逻辑信道组)中的数据的性能要求较高,例如,高优先级的Numerology的数据对传输时延要求高;低优先级的Numerology中的数据的性能要求较低,例如,低优先级Numerology中的数据对传输时延要求低。
高优先级的逻辑信道中的数据也可以称为高优先级的数据;低优先级的逻辑信道中的数据也可以称为低优先级的数据。通常情况下,高优先级的数据中需要优先传输。
可选地,作为一种实现方式,第一逻辑信道可以属于第一逻辑信道组,该第一逻辑信道组可以包括一个逻辑信道也可以包括多个逻辑信道。在第一逻辑信道组包括多个逻辑信道时,该第一逻辑信道组中所包括的多个逻辑信道的对应的Numerology相同。同样地,第二逻辑信道也可以属于第二逻辑信道组,第二逻辑信道组可以包括一个逻辑信道,也可以包括多个逻辑信道。在第二逻辑信道组包括多个逻辑信道时,该第二逻辑信道组中所包括的多个逻辑信道的对应的Numerology相同。
可以理解,逻辑信道组与Numerology的映射关系可以是通过RRC信令配置的,也可以是媒体介入控制层(Media Access Control,MAC)信令指示的。逻辑信道组与Numerology的对应关系,可以是逻辑信道组的ID与numerology相对应,也可以是逻辑信道组ID与numerology中的某一个特性相对应,比如TTI长度。
可选地,作为一种实现方式,该第二通信物理特性的优先级高于该第一通信物理特性的优先级,和/或该第二数据的优先级高于该第一数据的优先级。
因此,本申请实施例通过在第一数据对应的第一资源上发送较高优先级的第二数据,优先保证了高优先级数据的传输。
可选地,作为一种实现方式,该终端设备在该第一资源上发送上行数据,包括:
在满足以下条件之一或者全部的情况下,该终端设备在该第一资源上发送该上行数据:
该第一资源的数据量大于或等于该第二数据的数据量;
该终端设备在该第一资源上传输该第二数据的完成时刻早于该终端设备估计的利用第二通信物理特性对应的上行资源发送第二数据的完成时刻。
可选地,终端设备在发送第二数据之前,需要确定第一资源满足传输第二数据的条件。
例如,终端设备需要确定该第一资源的数据量大于该第二数据的数据量,这样能够保证第二数据的全部数据承载在第一资源上。
应理解,第一资源的数据量可以指该第一资源能够承载的最大数据量。
另外由于第一通信物理特性不同于第二通信物理特性。因此,在终端设备采用第一通信物理特性传输第二数据时,该第一资源传输该第二数据的结束时刻可能会晚于专门用于传输第二数据的上行资源传输该第二数据的结束时刻。由于,第二数据需要及时传输,为了避免采用第一资源传输第二数据的结束时刻较晚,终端设备在传输第二数据之前,终端设备需要确定该终端设备在该第一资源上传输该第二数据的完成时刻早于该终端设备估计的利用第二通信物理特性对应的上行资源发送第二数据的完成时刻。在通过第一资源传输第二数据的结束时刻较早的情况下,该终端设备才通过第一资源传输该第二数据。这样能够保证第二数据的及时传输。在通过第一资源传输第二数据的结束时刻较晚的情况下,可以使用的方案是,不把第二数据放在第一资源传输,或者不进行第一数据和第二数据在所述第一资源的复用过程。可以按照现有的传输方式,比如,该终端设备确定不满足上述条件的情况时,在第一资源上发送第一数据,对应的在第二资源上发送第二数据。
可选地,作为一种实现方式,该上行授权信息还包括用于指示该第一通信物理特性的信息;
该第二数据是该终端设备采用该第一通信物理特性发送的。
可选地,第一通信物理特性可以是该上行授权信息指示的;终端设备根据该上行授权信息的指示,采用第一通信物理特性发送该第二数据。
可选地,作为一种实现方式,在该终端设备接收网络设备发送的上行授权信息之前,该方法还包括:
该终端设备接收网络设备发送的调度消息,该调度消息指示该第二通信物理特性,
其中,该第二数据是该终端设备在该第一资源上采用该第二通信物理特性发送的。
可选地,该第二通信物理特性为网络设备发送的调度信息指示的,例如该调度信息为在该上行授权信息之前网络设备发送的历史调度信息,终端设备根据该历史的调度信息的指示,采用第二通信物理特性发送该第二数据。这样所述终端设备可以在发送请求消息之前,知晓上述第二通信物理特性的信息,而不必另外再发送请求消息来获得第二物理通信特性的信息。
可选地,作为一种实现方式,该上行数据还包括该第一数据。
可选地,在第一资源的数据量大于第二数据的数据量时,为了避免资源的浪费,本申请实施例中第一资源传输的上行数据还可以包括第一数据中的全部或部分数据。
因此,本申请实施例中,终端设备可以优先通过该第一资源传输较高优先级的第二数据。并且当有资源剩余时,复用较低优先级的第一数据,从而本申请实施例中优先保证了高优先级通信物理特性对应的数据的传输,进而能够减少或避免资源浪费。
现有技术中,分配给第一数据的资源没有被第一数据的数据量充分使用,造成资源的浪费。而且现有技术中,也没有更快途径发送已经确定要发送的第二数据。而本申请实施例中可以同时传输第二数据和第一数据,因而节省了资源因此,本申请实施例能够优先保证高优先级的数据的传输。同时,将闲置的资源充分利用起来。即在传输第二数据的基础上也传输第一数据,进而降低或避免了资源的浪费,实现合理的上行数据的传输。
可选地,作为一种实现方式,该上行数据包括该第一数据的一部分,该上行数据还包括第一缓冲调度请求,该第一缓冲调度请求用于指示该第一数据的剩余的第一数据量。
可以理解,由于该上行数据仅包括该第一数据的一部分,该第一数据还有剩余部分需要发送,因此,本申请实施例中可以在该上行资源中发送给第一缓冲调度请求,请求传输该剩余部分的发送资源。
应理解,该第一缓冲调度请求可以为BSR消息,该剩余的第一数据量可以为该第一数据中除了上行数据所包含的部分的部分。终端设备可以根据第一数据的总数量与上行数据包含的部分数据量的差值确定该剩余的第一数据量。
因此,在本申请实施例中还可以在该第一资源上传输第一缓冲调度请求,实现对第一数据中剩余部分的调度,实现了第一数据的完整传输,因此,本申请实施例既能保证高优先级的数据的传输,也保证了低优先级数据的完整传输。
可选地,作为一种实现方式,在该终端设备在该第一资源上发送上行数据之后,该方法还包括:
该终端设备发送第二缓冲调度请求,该第二缓冲调度请求用于指示该第二通信物理特性对应的该第二数据的数据量。
可选地,终端设备可以通过以下过程发送该第二BSR:该终端设备可以先通过向网络 设备发送第二SR,该第二SR用于获取发送第二BSR的资源,在网络设备接收到第二SR后,授权用于发送第二BSR的资源,之后,该终端设备在获取到该授权资源上发送该第二BSR。
可以理解,在终端设备通过第一资源传输该上行数据后,终端设备通过发送第二BSR可以向网络设备请求重新传输该第二数据,因此,通过发送第二BSR能够增加第二数据传输的可靠性。
第二方面,提供了一种传输数据的方法,包括:
网络设备接收终端设备发送的请求消息,该请求消息用于请求第一通信物理特性对应的第一资源,该第一资源用于发送第一通信物理特性对应的第一数据;

该网络设备在该第一资源上接收该终端设备发送的上行数据,该上行数据包括第二通信物理特性对应的第二数据。
因此,通过在第一通信物理特性对应的第一资源发送包含第二通信物理特性对应的第二数据的上行数据,可以合理的进行上行数据的传输。
更进一步地,在第二数据的优先级高于第一数据的优先级时,本申请实施例通过在调度授权的第一数据对应的第一资源上发送较高优先级的第二数据,优先保证了高优先级数据的传输。
应理解,该第二方面与上述第一方面对应,第二方面的执行主体为网络设备,第一方面中的执行主体可以为终端设备,网络设备侧的方法的相应特征以及对应的有益效果可以参见上述第一方面终端设备侧的相应描述,因此,为了简洁,适当省略详细描述。

该第二数据的优先级高于该第一数据的优先级。
可选地,作为一种实现方式,该第一资源的数据量大于或等于该第二数据的数据量;

具体实施方式
下面将结合附图,对本申请实施例中的技术方案进行描述。
应理解,本申请实施例可应用于各种通信系统,因此,下面的描述不限制于特定通信系统。例如,本申请实施例可以应用于全球移动通信(Global System of Mobile communication,GSM)系统、码分多址(Code Division Multiple Access,CDMA)系统、宽带码分多址(Wideband Code Division Multiple Access,WCDMA)系统、通用分组无线业务(General Packet Radio Service,GPRS)、长期演进(Long Term Evolution,LTE)系统、LTE频分双工(Frequency Division Duplex,FDD)系统、LTE时分双工(Time Division Duplex,TDD)、通用移动通信系统(Universal Mobile Telecommunication System,UMTS)等。
本申请实施例中,终端设备也可以称为用户设备(UE,User Equipment)、接入终端、用户单元、用户站、移动站、移动台、远方站、远程终端、移动设备、用户终端、终端、无线通信设备、用户代理或用户装置。接入终端可以是蜂窝电话、无绳电话、会话启动协议(Session Initiation Protocol,SIP)电话、无线本地环路(Wireless Local Loop,WLL)站、个人数字处理(Personal Digital Assistant,PDA)、具有无线通信功能的手持设备、计算设备或连接到无线调制解调器的其它处理设备、车载设备、可穿戴设备以及未来5G网络中的终端设备。
本申请实施例中,网络设备可以是网络侧设备等用于与移动设备通信的设备,网络侧设备可以是全球移动通信(Global System of Mobile communication,GSM)或码分多址(Code Division Multiple Access,CDMA)中的基站(Base Transceiver Station,BTS),也可以是宽带码分多址(Wideband Code Division Multiple Access,WCDMA)中的基站(NodeB,NB),还可以是长期演进(Long Term Evolution,LTE)中的演进型UMTS陆地无线接入网中的基站(Evolved UMTS Terrestrial Radio Access Network Node B,E-UTRAN Node B或eNB或eNodeB),或者中继站或接入点,或者车载设备、可穿戴设备以及未来5G网络中的网络侧设备。
图1是本申请实施例可应用的通信系统的场景图。在图1中,该通信系统包括网络设备和终端设备,该网络设备和该终端设备通过蜂窝网络资源进行通信。举例来说,图1中终端设备可以向网络设备申请上行资源,网络设备在获取到终端设备的申请后,可以通过上行授权信息,授权终端设备可以使用的上行资源,在终端设备获取到上行资源后,在该资源上发送上行数据。
具体而言,在实际应用中,在终端设备需要传输上行数据时,终端设备可以先向网络设备传输调度请求(Scheduling Request,SR),例如可以通过物理上行控制信道(Physical Uplink Control Channel,PUCCH)传输该SR,该SR用于指示该终端设备有数据传输的需求,这里SR中可以仅用于通知网络设备该终端设备有传输需求,SR中可以不包括具体的 传输数据量等信息。网络设备在获取到SR后,通过上行授权信息(UL grant)先为该终端设备配置一小部分资源,该一小部分资源能够满足传输缓冲调度请求,例如,缓冲区状态报告(Buffer Status Report,BSR),终端设备通过该一小部分资源传输该缓冲调度请求,通知网络设备自身传输的数据量等信息。可以理解,有发送BSR的资源的情况下,终端设备可以直接发送BSR而不必专门启动SR,但是若没有现成的发送BSR的资源,终端设备则需要启动SR,来请求资源。网络设备获取到BSR后为该终端设备分配上行资源。终端设备获取到上行资源后,在该资源上发送上行数据。
应理解,终端设备获取上行资源的具体过程,可以参照现有标准中的描述,此处不再赘述。
通信物理特性可以被称为Numerology。该通信物理特性对应通信系统中所采用的不同的参数的集合。不同的Numerology对应的参数可以不同。包括而不限定的,该通信物理特性为以下参数之一或者任意的组合的集合:子载波宽度、循环前缀(Cyclic Prefix,CP)长度、传输时间间隔(Transmission Time Interval,TTI)、符号(Symbol)个数、资源块(Resource Block,RB)位置、时隙长度和帧格式等。作为举例,读者可以从www.3gpp.org获得提案R1-1613779或者R2-168012来理解该通信物理特性Numerology的含义,这些提案的内容包含在本申请的内容中。因为3GPP标准组织的公正性和公开性,这里不再赘述。
不同的Numerology对应的数据可以具有不同的优先级。例如,短的TTI对应的Numerology的优先级高于长的TTI对应的Numerology的优先级。作为示例而非限定的说明,第一Numerology和第二Numerology的比较一般是指相同参数的比较。比如,都是针对TTI的比较,即第一TTI与第二TTI的相关比较。
现有的授权信息调度终端设备在上行资源上传输第一通信物理特性(Numerology 1)对应的第一数据(例如,低优先级的数据)时,终端设备在获取到上行资源后,仅在该资源上传输第一数据。然而,这种情况下,该上行资源上可能会存在资源剩余,或在其他通信物理特性,例如,较高优先级的第二通信物理特性(Numerology 2)对应的第二数据(高优先级的数据)需要传输时,需要重新请求上行资源等过程,造成该第二数据需要较长的等待时间,导致高优先级的数据无法及时传输。
基于现有技术的问题,本申请实施例巧妙的提出了不同的Numerology对应的数据复用的方法。具体地,在本申请实施例中,在终端设备获取到网络设备授权的Numerology 1对应的第一资源后,终端设备可以优先通过该上行资源传输Numerology 2对应的第二数据。或通过第一资源传输第二数据的基础上还有资源剩余时,复用该第一数据,减少资源浪费。从而本申请实施例中优先保证了高优先级的数据的传输,可以合理的进行上行数据的传输。
以下,为了便于理解和说明,作为示例而非限定,以将本申请的传输数据的方法在通信系统中的执行过程和动作进行说明。
图2是根据本申请一个实施例的传输数据的方法示意图。如图2所示的方法可以应用于上述各种通信系统中,本申请实施例中的通信系统包括网络设备和终端设备。具体地,如图2所示的方法200包括:
210,终端设备向网络设备发送请求消息。
具体地,终端设备向网络设备发送请求消息,该请求消息用于请求第一通信物理特性 对应的第一资源,该第一资源用于发送第一通信物理特性对应的第一数据。
具体而言,在终端设备需要发送第一通信物理特性对应的第一数据时,该终端设备向网络设备发送请求消息,该请求消息也可以称为缓冲调度请求消息,例如为BSR,该BSR可以指示该第一数据的数据量。
220,网络设备向终端设备发送上行授权消息。
具体地,网络设备获取到终端设备发送的请求消息后,向终端设备发送上行授权消息。该上行授权信息包括用于指示该终端设备使用的该第一资源的信息。
例如,该上行授权消息用于指示终端设备在该第一资源上传输第一数据。
可选地,该上行授权消息可以只包含针对第一通信物理特性的调度信息,例如,该上行授权消息可以包括终端设备发送第一数据的时隙长度、调制编码方案(Modulation and Coding Scheme,MCS)、该第一资源的位置或者第一数据的Numerology的其他参数等,本申请实施例并不限于此。
可选地,在本申请实施例中,该第一数据是属于第一逻辑信道的,第一逻辑信道与第一通信物理特性(Numerology 1)存在第一映射(Mapping)关系;该第二数据是属于第二逻辑信道的,第二逻辑信道与第二通信物理特性(Numerology 1)存在第二映射(Mapping)关系;
可选地,Numerology 2的优先级高于Numerology 1的优先级。可选的,该第二逻辑信道的优先级高于该第一逻辑信道的优先级。可选的,该第二数据的优先级高于该第一数据的优先级。
可选地,该第一数据是属于第一逻辑信道组的,该第一逻辑信道组与第一通信物理特性存在第一映射(MAPPING)关系,该第二数据是属于第二逻辑信道组的,该第二逻辑信道组与第二通信物理特性存在第二映射(MAPPING)关系,Numerology 2的优先级高于Numerology 1的优先级,该第二逻辑信道组的优先级高于该第一逻辑信道组的优先级。该第二数据的优先级高于该第一数据的优先级。
可选地,该第一映射关系、该第二映射关系是通过信令发送的。例如,终端设备可以通过无线资源控制(Radio Resource Control,RRC)信令接收网络设备发送的该第一映射关系、该第二映射关系。
具体而言,在本申请实施例中,Numerology与逻辑信道(或者逻辑信道组)具有映射关系,例如,高优先级的Numerology对应高优先级的逻辑信道(或者逻辑信道组),低优先级的Numerology对应低优先级的逻辑信道(或者逻辑信道组)。高优先级的逻辑信道(或者逻辑信道组)中的数据的性能要求较高,例如,高优先级的Numerology的数据对传输时延要求高;低优先级的Numerology中的数据的性能要求较低,例如,低优先级Numerology中的数据对传输时延要求低。
高优先级的逻辑信道中的数据也可以称为高优先级的数据;低优先级的逻辑信道中的数据也可以称为低优先级的数据。通常情况下,高优先级的数据需要优先传输。
在本申请实施例中,第一逻辑信道可以属于第一逻辑信道组,该第一逻辑信道组可以包括一个逻辑信道也可以包括多个逻辑信道,在第一逻辑信道组包括多个逻辑信道时,该第一逻辑信道组中所包括的多个逻辑信道的对应的Numerology相同。同样地,第二逻辑信道也可以属于第二逻辑信道组,第二逻辑信道组可以包括一个逻辑信道,也可以包括多 个逻辑信道,在第二逻辑信道组包括多个逻辑信道时,该第二逻辑信道组中所包括的多个逻辑信道的对应的Numerology相同。在本申请实施例中以第一逻辑信道的优先级低于第二逻辑信道的优先级,Numerology 2的优先级高于该Numerology 1的优先级,或者该第二数据的优先级高于该第一数据的优先级为例进行说明。
可以理解,逻辑信道组与Numerology的映射关系可以是通过RRC信令配置的,也可以是媒体接入控制层(Media Access Control,MAC)信令指示的。逻辑信道组与Numerology的对应关系,可以是逻辑信道组的ID与numerology相对应,也可以是逻辑信道组ID与numerology中的某一个特性相对应,比如TTI长度。
应理解,本申请实施例中,该第一数据为优先级较低的数据,例如,第一数据为对服务质量(Quality of Service,QoS)或延时要求较低的数据,例如,该第一数据为浏览网页、发送邮件或网盘时的上行数据。本申请实施例中,第二数据为对QoS或延时要求较高的数据,例如,用户通过终端设备进行无线控制时的上行数据,例如,终端设备在通过无线网络控制无人机等产生的上行数据,为了能够较好的实现无线控制,该上行数据需要低时延且需要及时传输。
本申请实施例并不对第一数据和第二数据的具体内容做限定。第一数据和第二数据还可以为其他类型的数据,本申请实施例并不限于此。
230,该终端设备在该第一资源上发送上行数据。
具体地,终端设备获取到该第一资源的信息后,终端设备在该第一资源上发送上行数据,该上行数据包括第二通信物理特性对应的第二数据。
因此,本申请实施例通过在第一通信物理特性对应的第一资源上发送包含第二通信物理特性对应的第二数据的上行数据,可以合理的进行上行数据的传输。
更进一步地,在第二数据的优先级高于第一数据的优先级时,本申请实施例通过在第一数据对应的第一资源上发送较高优先级的第二数据,优先保证了高优先级数据的传输。
可选地,终端设备可以在第一资源上采用第一通信物理特性传输该第二数据,也可以在第一资源上采用第二通信物理特性传输该第二数据。这取决于通信物理特性带来的技术特点,即哪个可以优先保障高优先的传输。
可选地,作为另一实施例,该上行授权信息还包括用于指示该第一通信物理特性的信息;
其中,该第二数据是该终端设备在采用该第一通信物理特性发送的。
具体地,第一通信物理特性可以是该上行授权信息指示的;终端设备根据该上行授权信息的指示,采用第一通信物理特性发送该第二数据。
可替代地,作为另一实施例,该方法还可以包括:
该终端设备接收网络设备发送的调度消息,该调度消息指示该第二通信物理特性,
其中,该第二数据是该终端设备在该第一资源上采用该第二通信物理特性发送的。
具体地,该第二通信物理特性为网络设备发送的调度信息指示的,例如该调度信息为在该上行授权信息之前网络设备发送的历史调度信息,终端设备根据该历史的调度信息的指示,采用第二通信物理特性发送该第二数据。
可选地,作为另一实施例,在230中,在满足以下条件之一或全部的情况下,该终端设备在该第一资源上发送该上行数据:
该第一资源的数据量大于或等于该第二数据的数据量;
该终端设备在该第一资源上传输该第二数据的完成时刻早于该终端设备估计的利用第二通信物理特性对应的上行资源发送第二数据的完成时刻。
具体而言,终端设备在发送第二数据之前,需要确定第一资源满足传输第二数据的条件。
例如,终端设备需要确定该第一资源的数据量大于该第二数据的数据量,这样能够保证第二数据的全部数据承载在第一资源上。
应理解,第一资源的数据量可以指该第一资源能够承载的最大数据量。
另外由于第一通信物理特性不同于第二通信物理特性。因此,在终端设备采用第一通信物理特性传输第二数据时,该第一资源传输该第二数据的结束时刻可能会晚于专门用于传输第二数据的上行资源传输该第二数据的结束时刻。由于,第二数据需要及时传输,为了避免采用第一资源传输第二数据的结束时刻较晚,终端设备在传输第二数据之前,终端设备需要确定该该终端设备在该第一资源上传输该第二数据的完成时刻早于该终端设备估计的利用第二通信物理特性对应的上行资源发送第二数据的完成时刻。在通过第一资源传输第二数据的结束时刻较早的情况下,该终端设备才通过第一资源传输该第二数据。这样能够保证第二数据的及时传输。在通过第一资源传输第二数据的结束时刻较晚的情况下,可以使用的方案是,不把第二数据放在第一资源传输,或者不进行第一数据和第二数据在所述第一资源的复用过程。可以按照现有的传输方式,比如,该终端设备确定不满足上述条件的情况时,在第一资源上发送第一数据,对应的在第二资源上发送第二数据。
例如,如图3所示,在终端设备获取到第一通信物理特性对应的第一资源后,由于第二通信物理特性的优先级高于第一通信物理特性对应的优先级,和/或该第二数据的优先级高于该第一数据的优先级,终端设备在判断第一资源满足传输第二数据的条件下,终端设备在该第一资源上传输第二数据。
需要说明的是,在第一资源的数据量大于第二数据的数据量时,为了避免资源的浪费,本申请实施例中第一资源传输的上行数据还可以包括第一数据。
例如,在第一资源的数据量大于第二数据的数据量,且小于第一数据和第二数据的数据量之和时,该上行数据包括第二数据和部分第一数据。在第一资源的数据量大于或等于第一数据和第二数据的数据量之和时,该上行数据可以包括第二数据和全部的第一数据。
因此,本申请实施例中,终端设备可以优先通过该第一资源传输较高优先级的第二数据。并且当有资源剩余时,复用较低优先级的第一数据,从而本申请实施例中优先保证了高优先级通信物理特性对应的数据的传输,进而能够减少或避免资源浪费。
例如,如图4所示,在终端设备获取到第一通信物理特性对应的第一资源后,由于该第二通信物理特性的优先级高于该第一通信物理特性的优先级,和/或该第二数据的优先级高于该第一数据的优先级,终端设备在判断第一资源满足传输第二数据的条件下,终端设备在该第一资源上传输第二数据。可选地,在第一资源的数据量较多的情况下,终端设备还可以在该第一资源上传输该第一数据。例如,如图4所示,在该第一资源中,该第二通信物理特性对应的第二数据(如图4中的灰色方块)放置的时域位置位于该第一通信物理特性对应的第一数据(如图4中的白色方块)放置的时域位置之前。
现有技术中,分配给第一数据的资源没有被第一数据的数据量充分使用,造成资源的 浪费。而且现有技术中,也没有更快途径发送已经确定要发送的第二数据。而本申请实施例中可以同时传输第二数据和第一数据,因而节省了资源。因此,本申请实施例能够优先保证高优先级的数据的传输。同时,将闲置的资源充分利用起来。即在传输第二数据的基础上也传输第一数据,进而降低或避免了资源的浪费,实现合理的上行数据的传输。
需要说明的是,在上行数据包括第二数据和第一数据时,在该第一资源中该第二数据对应的时域资源位置可以位于该第一数据对应的时域资源位置之前。
可选地,作为另一实施例,在该上行数据包括该第一数据的一部分,该上行数据还包括第一缓冲调度请求,该第一缓冲调度请求用于指示该第一数据的剩余的第一数据量。
具体而言,由于该上行数据仅包括该第一数据的一部分,该第一数据还有剩余部分需要发送,因此,本申请实施例中可以在该上行资源中发送给第一缓冲调度请求,请求传输该剩余部分的发送资源。
应理解,该第一缓冲调度请求可以为BSR消息,该剩余的第一数据量可以为该第一数据中除了上行数据所包含的部分,终端设备可以根据第一数据的总数量与上行数据包含的部分数据量的差值确定该剩余的第一数据量。
因此,在本申请实施例中还可以在该第一资源上传输第一缓冲调度请求,实现对第一数据中剩余部分的调度,实现了第一数据的完整传输,因此,本申请实施例既能保证高优先级的数据的传输,也保证了低优先级数据的完整传输。
其中,该第一缓冲调度请求可以为第一BSR。其中,第一BSR与第一数据和第二数据的时域位置不做限定。例如,如图5所示,该第二数据的时域位置位于第一BSR的时域位置之前,该第一BSR的时域位置为第一数据的时域位置之前。
具体地,如图5所示,在终端设备获取到第一通信物理特性对应的第一资源后,可以知晓第二通信物理特性的优先级高于第一通信物理特性对应的优先级,和/或该第二数据的优先级高于该第一数据的优先级,反之亦然。终端设备在判断第一资源满足传输第二数据的条件下,终端设备在该第一资源上传输第二数据。可选地,在第一资源承载的数据量较多的情况下,终端设备还可以在该第一资源上传输该第一数据中的全部或部分数据,并且终端设备还可以在该第一资源上传输第一BSR。例如,如图5所示,在该第一资源中,该第二通信物理特性对应的第二数据(如图5中的灰色方块)放置的时域位置位于该第一BSR(如图5中第二数据对应的灰色方块之后的第一个白色方块)放置的时域位置之前,该第一BSR放置的时域位置位于该第一通信物理特性对应的第一数据(如图5中第二数据对应的灰色方块之后的第二个白色方块)放置的时域位置之前。
由于第二数据的优先级较高,为了保证第二数据的可靠传输,在本申请实施例中,在终端设备通过第一资源传输该上行数据后,终端设备还可以向网络设备请求重新传输该第二数据,即终端设备可以向网络设备发送第二缓冲调度请求,例如为第二BSR,该第二缓冲调度请求用于指示该第二通信物理特性对应的该第二数据的数据量。
因此,本申请实施例通过发送第二BSR能够增加第二数据传输的可靠性。
例如,如图6所示,在终端设备需要发送第一通信物理特性对应第一数据时,终端设备向网络设备请求传输该第一数据,网络设备根据终端设备的请求可以为该终端设备授权传输该第一数据的第一资源。进而,可以确定第二通信物理特性的优先级高于第一通信物理特性对应的优先级,和/或该第二数据的优先级高于该第一数据的优先级,反之亦然, 因此,终端设备在获取到第一资源后,在该第一资源上发送上行数据,该上行数据包括第二数据,可选地,该上行数据还可以包括第一BSR,和部分或全部第一数据。例如,如图6所示,在该第一资源中,该第二通信物理特性对应的第二数据(如图6中的灰色方块)放置的时域位置位于该第一BSR(如图6中第二数据对应的灰色方块之后的第一个白色方块)放置的时域位置之前,该第一BSR放置的时域位置位于该第一通信物理特性对应的第一数据(如图6中第二数据对应的灰色方块之后的第二个白色方块)放置的时域位置之前。之后,该终端设备还可以发送第二BSR(如图6中最后一个白色方块),以向网络设备请求重新传输该第二数据并指示该第二数据的数据量。
具体地,终端设备可以通过以下过程发送该第二BSR:该终端设备可以先通过向网络设备发送第二SR,该第二SR用于获取发送第二BSR的资源,在网络设备接收到第二SR后,授权用于发送第二BSR的资源,之后,该终端设备在获取到该授权资源上发送该第二BSR。
因此,本申请实施例通过发送第二缓冲调度请求可以向网络设备请求重新传输该第二数据,保证了高优先级的第二数据的传输可靠性。
