Description

数据包传输方法和设备
本申请要求于2017年5月5日递交中国国家知识产权局、申请号为2017103153943，发明名称为“数据包传输方法和设备”的国内专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本发明涉及数据传输领域，尤其涉及一种数据包传输方法和设备。
背景技术
在传统通信系统中，单个用户同时具有多种不同类型的业务，这些业务需要不同的服务质量(Quality of Service，QoS)，例如时延、速率等。一般来说，不同QoS需求的业务会被划分到不同的逻辑信道中，某些逻辑信道具有较高的数据传输优先级，某些逻辑信道的数据传输优先级比较低。如果采用轮流调度的方式，高的数据传输优先级的逻辑信道对应的业务服务质量可能难以满足，如果始终优先满足高的数据传输优先级的逻辑信道对应的业务需求，就会出现低的数据传输优先级的逻辑信道对应的业务需求可能长期得不到满足的境况。
在长期演进(Long Term Evolution,LTE)中，当上行调度资源(Uplink grant)到达时，不同逻辑信道的数据可以复用到一个媒体接入控制层协议数据单元(Media Access Control Protocol Date Unit,MAC PDU)中。逻辑信道具有固定的数据传输优先级，通过采用令牌桶机制进行数据包的复用。这种方式既可以优先保障高的数据传输优先级的逻辑信道的业务，又同时保障了低的数据传输优先级的逻辑信道的业务。但这种方式的主要缺点是将就有不同QoS需求的数据包装载到一个MAC PDU中，并在物理层采用相同的传输参数发送该MAC PDU。通过相同传输参数传输具有不同QoS需求的逻辑信道中的业务，这难以实现业务和资源的匹配。

上述终端设备101在向上述基站102发送数据包之前，该基站102向上述终端设备101发送配置信息；该终端设备101根据配置信息中的上行调度资源的通信物理特性和逻辑信道对应的通信物理特性确定逻辑信道的数据传输优先级，接着终端设备101根据逻辑信道的数据传输优先级顺序将逻辑信道中的数据装在到MAC PDU中，并在上行调度资源上以上行调度资源的通信物理特性将该MAC PDU发送至上述基站102。
其中，上述通信物理特性又称为“Numerology”。通信物理特性为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。该通信物理特性对应但不限定以下参数中的一种或多种：子载波宽度(subframe spacing，又称子载波间隔)、循环前缀(Cyclic Prefix，CP)长度、符号(Symbol)个数、资源块(Resource Block，RB)位置、时隙长度和帧格式等。不同的通信物理特性可以对应上述不同的参数。

上述上行调度资源通信物理特性标识用于指示对应的通信物理特性；
可选的，上述上行调度资源通信物理特性标识可以用于计算得到对应的通信物理特性。例如，假定通信物理特性只包含子载波宽度，且该子载波宽度可以通过公式15kHz*2 n来计算获得，其中n可以为非负整数或者负整数，则通信物理特性标识可以指n。
S202、所述终端设备确定N个逻辑信道中每个逻辑信道对应的数据传输优先级。
具体地，所述终端设备确定N个逻辑信道中每个逻辑信道对应的数据传输优先级具体包括：
当逻辑信道A的第一优先级高于逻辑信道B的第一优先级时，所述终端设备确定所述逻辑信道A的数据传输优先级为第一数据传输优先级和所述逻辑信道B的数据传输优先级为第二数据传输优先级；
其中，所述第一数据传输优先级高于所述第二数据传输优先级，即优先将所述逻辑信道A的数据装载到所述MAC PDU中，所述逻辑信道A和所述逻辑信道B为所述N个逻辑信道中的任意两个逻辑信道；
所述逻辑信道A的第一优先级由基站通过RRC信令或者SIB进行配置或者预配置在所述终端设备侧，所述逻辑信道B的第一优先级由基站通过所述RRC信令或者所述SIB进行配置或者预配置在所述终端设备侧。
其中，上述第一优先级可以用于确定逻辑信道数据传输优先级。
可选地，上述逻辑信道A的第一优先级是基站向终端设备发送上述RRC信令或者上述SIB，进而为逻辑信道配置的；上述逻辑信道B的第一优先级是基站向终端设备发送上述RRC信令或者上述SIB，进而为上述逻辑信道A和上述逻辑信道B配置的。
可选地，上述逻辑信道A的第一优先级是预配置在终端设备侧的；上述逻辑信道B的第一优先级是预配置在终端设备侧的。
可选地，上述逻辑信道A的第一优先级也可以是逻辑信道A中数据的时延需求。当逻辑信道A中数据的时延需求小于逻辑信道B中数据的时延需求时，逻辑信道A的第一优先级高于逻辑信道B的第一优先级。
其中，上述逻辑信道中数据的时延需求可以指但不限于逻辑信道中数据包的端到端时延需求、逻辑信道中数据包的单向传输时延需求、逻辑信道中数据包的空口传输时延需求、逻辑信道中数据包的TTI需求中的一项或者多项；其中上述逻辑信道中数据包的时延需求可以由基站通过上述RRC信令或者上述SIB进行配置或者预配置在所述终端设备侧。
举例说明，比如逻辑信道A和逻辑信道B的数据包空口传输时延需求分别为0.5ms和1ms，则逻辑信道A的第一优先级高于逻辑信道B的第一优先级，即上述终端设备优先将上述逻辑信道A的数据装载到MAC PDU中。

上述终端设备无法根据上述逻辑信道A对应的通信物理特性、上述逻辑信道B对应的通信物理特性和上述上行调度资源的通信物理特性确定上述逻辑信道A和上述逻辑信道B的数据传输优先级。此时需要引入一个逻辑信道的第二优先级，上述终端设备根据逻辑信道的第二优先级确认逻辑信道的数据传输优先级，具体如下：
上述终端设备确定上述逻辑信道A的第二优先级和上述逻辑信道B的第二优先级；
当上述逻辑信道A的第二优先级高于上述逻辑信道B的第二优先级，则上述终端设备确定上述逻辑信道A的数据传输优先级为第一数据传输优先级和上述逻辑信道B的数据传输优先级为第二数据传输优先级；反之，述终端设备确定上述逻辑信道B的数据传输优先级为第一数据传输优先级和上述逻辑信道A的数据传输优先级为第二数据传输优先级；
上述第一数据传输优先级高于第二数据传输优先级。
具体地，所述终端设备确定N个逻辑信道中每个逻辑信道对应的数据传输优先级具体包括：
当所述逻辑信道A对应的默认通信物理特性中的任意一个通信物理特性与所述上行调度资源的通信物理特性一致，所述逻辑信道B对应的默认通信物理特性中的每个通信物理特性均与所述上行调度资源的通信物理特性不一致时；或者，

所述终端设备确定所述逻辑信道A的数据传输优先级为第一数据传输优先级和所述逻辑信道B的数据传输优先级为第二数据传输优先级，所述第一数据传输优先级高于所述第二数据传输优先级，即优先将逻辑信道A的数据装载到所述MAC PDU中；

当上述逻辑信道A的默认通信物理特性包括Numerology1和Numerology2，上述逻辑信道B的默认通信物理特性包括Numerology2和Numerology3且上述上行调度资源的通信物理特性为Numerology1时，由于上述逻辑信道A的对应的默认通信物理特性包括Numerology1，与上述上行调度资源的通信物理特性(Numerology1)一致，且上述逻辑信道B对应的默认通信物理特性(Numerology2和Numerology3)与上述上行调度资源的通信物理特性(Numerology1)都不一致，故上述终端设备确定上述逻辑信道A的数据传输优先级为第一数据传输优先级，上述逻辑信道B的数据传输优先级为第二数据传输优先级。
当上述逻辑信道A的默认通信物理特性包括Numerology1和Numerology2、上述逻辑信道A的可选通信物理特性包括Numerology3和Numerology4、上述逻辑信道B的可选通信物理特性包括Numerology1和Numerology2、上述逻辑信道B的默认通信物理特性包括Numerology3和Numerology5且上述上行调度资源的通信物理特性为Numerology4时，由于上述逻辑信道A对应的默认通信物理特性(Numerology1和Numerology2)、上述逻辑信道B对应的默认通信物理特性(Numerology1和Numerology2)和上述逻辑信道B对应的可选通信物理特性(Numerology3和Numerology5)都与上述上行调度资源的通信物理特性(Numerology4)都不一致，且上述逻辑信道A对应的可选通信物理特性(Numerology3和Numerology4)中的Numerology4与上述上行调度资源的通信物理特性(Numerology4)一致，故上述终端设备确定上述逻辑信道A的数据传输优先级为第一数据传输优先级，上述逻辑信道B的数据传输优先级为第二数据传输优先级。
当上述逻辑信道A对应的默认通信物理特性包括Numerology1和Numerology2，上述逻辑信道B未被配置对应的默认通信物理特性和可选通信物理特性，上述上行调度资源的通信物理特性为Numerology2，由于上述逻辑信道A对应的默认通信物理特性(Numerology1和Numerology2)中的Numerology2与上述上行调度资源的通信物理特性为Numerology2一致，可以理解为上述逻辑信道A对应的默认通信物理特性与上述上行调度资源的通信物理特性一致，上述逻辑信道B对应的默认通信物理特性与上述上行调度资源的通信物理特性不一致，故上述终端设备确定上述逻辑信道A的数据传输优先级为第一数据传输优先级，上述逻辑信道B的数据传输优先级为第二数据传输优先级。
当上述逻辑信道A对应的默认通信物理特性包括Numerology1和Numerology2，上述逻辑信道A对应的可选通信物理特性包括Numerology3和Numerology4，上述逻辑信道B未被配置对应的默认通信物理特性和可选通信物理特性，上述上行调度资源的通信物理特性为Numerology3，由于上述逻辑信道A对应的默认通信物理特性(Numerology1和Numerology2)均与上述上行调度资源的通信物理特性为Numerology3不一致，且上述逻辑信道A对应的可选通信物理特性(Numerology3和Numerology4)中的Numerology3与上述上行调度资源的通信物理特性为Numerology3一致，可以理解为，上述逻辑信道A和上 述逻辑信道B对应的默认通信物理特性均与上述上行调度资源的通信物理特性不一致，且上述逻辑信道A对应的可选通信物理特性与上述上行调度资源的通信物理特性一致，且上述逻辑信道B对应的可选通信物理特性与上述上行调度资源的通信物理特性不一致，故上述终端设备确定上述逻辑信道A的数据传输优先级为第一数据传输优先级，上述逻辑信道B的数据传输优先级为第二数据传输优先级。
当上述逻辑信道A未被配置对应的默认通信物理特性，上述逻辑信道A对应的可选通信物理特性包括Numerology3和Numerology4，上述逻辑信道B未被配置对应的可选通信物理特性，上述逻辑信道B对应的默认通信物理特性为Numerology5，上述上行调度资源的通信物理特性为Numerology3，由于上述逻辑信道A未被配置对应的默认通信物理特性，可以理解为上述逻辑信道A的默认通信物理特性与上述上行调度资源的通信物理特性不一致，逻辑信道B对应的默认通信物理特性(Numerology5)与上述上行调度资源的通信物理特性为Numerology3不一致，且上述逻辑信道A对应的可选通信物理特性(Numerology3和Numerology4)中的Numerology3与上述上行调度资源的通信物理特性为Numerology3一致，上述逻辑信道B未被配置对应的可选通信物理特性，可以理解，上述逻辑信道B的可选通信物理特性与上述上行调度资源的通信物理特性不一致，故上述终端设备确定上述逻辑信道A的数据传输优先级为第一数据传输优先级，上述逻辑信道B的数据传输优先级为第二数据传输优先级。
可选地，上述终端设备可根据逻辑信道对应的通信物理特性包含的参数确定N个逻辑信道中每个逻辑信道对应的数据传输优先级。上述参数包括子载波宽度、CP长度、符号个数、RB位置、时隙长度和帧格式中的至少一个。
比如，当上述逻辑信道A对应的通信物理特性中的符号个数比上述逻辑信道B对应的通信物理特性中的符号个数少时，上述终端设备确定上述逻辑信道A的数据传输优先级为第一数据传输优先级，上述逻辑信道B的数据传输优先级为第二数据传输优先级。
需要说明的是，上述第一数据传输优先级高于上述第二数据传输优先级，即优先将上述逻辑信道A的数据装载到上述MAC PDU中。
可选地，当只存在一个逻辑信道时，该逻辑信道的数据传输优先级最高，不需要进行逻辑信道数据传输优先级的确定。
S203、所述终端设备根据所述N个逻辑信道中每个逻辑信道对应的数据传输优先级，将N个逻辑信道中的M个逻辑信道的数据装载到MAC PDU中，所述M为小于或等于所述N的整数。
需要解释说明的是，终端设备将逻辑信道中的数据发送到基站具体是将该逻辑信道的数据装载到MAC PDU中，再通过上行调度资源将该MAC PDU发送至该基站。由于终端设备获取上行调度资源后，该上行调度资源的大小是固定的，因此终端设备在向上述MAC PDU中装载数据时，需要考虑上行调度资源的大小。
比如上述逻辑信道A和上述逻辑信道B中都有数据需要发送给基站，该逻辑信道A的数据传输优先级高于上述逻辑信道B的数据传输优先级，且上述上行调度资源的大小只能满足装载上述逻辑信道A中数据，此时，上述终端设备就只将数据传输优先级较高的逻辑信道A中数据装载到上述MAC PDU中。
若上述上行调度资源较大，上述终端设备将数据传输优先级较高的逻辑信道A中数据装载到上述MAC PDU后，上述上行调度资源还有空闲资源传输额外的数据，则上述终端设备将上述逻辑信道B中数据装载到上述MAC PDU中。
可选的，上述终端设备根据所述N个逻辑信道中每个逻辑信道对应的数据传输优先级，将N个逻辑信道中的M个逻辑信道的数据装载到MAC PDU中，对于某个确定的上行调度资源，按照逻辑信道数据传输优先级依次装载，每个逻辑信道装载到MAC PDU的数据量大小和/或占用的上行调度资源的时、频位置，本发明中不作限制，例如，单个逻辑信道初始装载到MAC PDU时的最大装入的数据量大小可以参照现有LTE机制(令牌桶机制)。
可选的，当所有N个逻辑信道都被服务之后，即所有N个逻辑信道中的数据都被装入MAC PDU中，此时仍然有上行调度资源剩余时，按照逻辑信道数据传输优先级依次装载，每个逻辑信道装载到MAC PDU的数据量大小和/或占用的上行调度资源的时、频位置，本发明中不作限制，例如可以参照LTE机制，尽量多的装配数据传输优先级较高的逻辑信道中的数据，而不再受初始装载最大数据量大小制约。
可选地，所述对应关系还包括与所述逻辑信道A对应的可选通信物理特性相对应的概率P 1，所述方法还包括：
当所述上行调度资源的通信物理特性与所述逻辑信道A对应的可选通信物理特性一致时，所述终端设备按照概率P 1将所述逻辑信道A中的数据装载到所述MAC PDU中。
具体地，上述终端设备在将上述逻辑信道A的数据装载到上述MAC PDU之前，上述终端设备生成一个随机概率P1，当该随机概率P1与上述概率P 1满足第一预设条件时，则上述终端设备将上述逻辑信道A的数据装载到上述MAC PDU中。
可选地，上述第一预设条件可为上述随机概率P1大于上述概率P 1、上述随机概率P1小于上述概率P 1、上述随机概率P1大于或者等于上述概率P 1、上述随机概率P1小于或者等于上述概率P 1，上述随机概率P1等于上述概率P 1或者其他条件。
可选地，所述方法还包括：
当所述上行调度资源无法满足逻辑信道C中数据的时延需求，则所述终端设备不将所述逻辑信道C的数据装载到所述MAC PDU中；
其中，上述逻辑信道C中数据的时延需求可以指但不限于逻辑信道中数据包的端到端时延需求、逻辑信道中数据包的单向传输时延需求、逻辑信道中数据包的空口传输时延需求、逻辑信道中数据包的传输时间间隔需求中的一项或者多项；
其中，当上述逻辑信道C中数据的时延需求为多项时，上述上行调度资源无法满足逻辑信道C中数据的时延需求是指无法满足多个时延需求中的某一项。
其中，所述逻辑信道C为所述N个逻辑信道中的任意一个逻辑信道，所述逻辑信道C中数据的时延需求是基站通过所述RRC信令或者所述SIB进行配置或者预配置在所述终端设备侧。
其中，上述逻辑信道中数据的时延需求可以指但不限于逻辑信道中数据包的端到端时延需求、逻辑信道中数据包的单向传输时延需求、逻辑信道中数据包的空口传输时延需求、逻辑信道中数据包的TTI需求中的一项或者多项；
具体地，上述终端设备将上述逻辑信道C的数据装载到上述MAC PDU之前，上述终端设备确认上述上行调度资源是否满足上述逻辑信道中数据的时延需求，当上述上行调度资源满足上述逻辑信道中数据的时延需求，则上述终端设备将上述逻辑信道C的数据装载到上述MAC PDU中；若上述上行调度资源无法满足上述逻辑信道中数据的时延需求，则上述终端设备不将上述逻辑信道C的数据装载到上述MAC PDU中。
可选地，上述逻辑信道C中数据的时延需求是上述基站向上述终端设备发送上述RRC信令或者SIB，进而为上述逻辑信道C配置的。
可选地，上述逻辑信道C中数据的时延需求是预配置在上述终端设备侧的。
举例说明，假定基站通过RRC信令配置的逻辑信道C中数据的空口传输时延需求为0.5ms,即逻辑信道C中所有数据包的空口传输时延都需要小于等于0.5ms。上述终端设备在接收到上行调度资源配置信息之后，需要时间进行收发转换等其它处理，当其确认上行调度资源无法满足0.5ms空口传输时延需求时，上述终端设备不将上述逻辑信道C的数据装载到上述MAC PDU中；
或者，由于数据传输优先级较高的逻辑信道中的数据需要首先占用了上行调度资源中的部分资源，考虑到收发转换等其它处理时间和被数据传输优先级较高的逻辑信道中的数据占用的上行调度资源的时、频率位置，剩余的上行调度资源难以满足上述逻辑信道C中数据的空口传输时延需求，此时上述终端设备不将上述逻辑信道C的数据装载到上述MAC PDU中；
或者，由于媒体接入控制层控制元素(Media Access Control Control Element，MAC CE)可能也需要占用上行调度资源中的部分资源，考虑到收发转换等其它处理时间、被数据传输优先级较高的逻辑信道中的数据占用的上行调度资源的时、频率位置、MAC CE占用的上行调度资源的时、频率位置中的一项或者多项，剩余的上行调度资源难以满足上述逻辑信道C中数据的空口传输时延需求，此时上述终端设备不将上述逻辑信道C的数据装载到上述MAC PDU中；
或者，假定基站配置的时延需求为端到端时延需求，终端设备考虑基站处理时延，收发转换时延、上行调度资源的时、频位置等，确定该上行调度资源难以满足端到端时延需求，则上述终端设备不将上述逻辑信道C的数据装载到上述MAC PDU中。
可选地，所述对应关系还包括与所述逻辑信道D对应的可选通信物理特性相对应的概率P 2，所述方法还包括：
当逻辑信道D对应的可选通信物理特性与所述上行调度资源的通信物理特性一致，且所述上行调度资源满足逻辑信道D中数据的时延需求时，所述终端设备按照概率P 2将所述逻辑信道D的数据装载到所述MAC PDU中，其中所述逻辑信道D为所述N个逻辑信道中的任意一个逻辑信道。
具体地，上述终端设备将上述逻辑信道D的数据装载到上述MAC PDU之前，上述终端设备生成一个随机概率P2，上述终端设备在确认上述上行调度资源是否满足上述逻辑信道D中数据的时延需求时，同时确认上述随机概率P2与上述概率P 2是否满足第二预设条件，当上述两个条件同时满足时，上述终端设备才将上述逻辑信道D中的数据装载到上述MAC PDU中；当上述两个条件中任意一个条件不满足时，上述终端设备不会将上述逻辑 信道D中的数据装载到上述MAC PDU中。
可选地，上述第二预设条件可为上述随机概率P2大于上述概率P 2、上述随机概率P2小于上述概率P 2、上述随机概率P2大于或者等于上述概率P 2、上述随机概率P2小于或者等于上述概率P 2，上述随机概率P2等于上述概率P 2或者其他条件。
S204、所述终端设备在所述上行调度资源上以所述上行调度资源的通信物理特性发送所述MAC PDU。
具体地，上述终端设备通过上行调度资源将上述MAC PDU按照上述上行调度资源的通信物理特性包含的参数所指示的形式发送上述MAC PDU。
可选的,所述MAC PDU中还可以包括缓冲区状态报告(Buffer Status Report，BSR)，用于指示逻辑信道组对应的缓冲区数据量大小；其中，上述缓冲区数据量大小指与所述逻辑信道组对应的分组数据汇聚协议(Packet Data Convergence Protocol，PDCP)层缓冲区数据量和与所述逻辑信道组对应的无线链路层控制(Radio Link Control，RLC)协议层缓冲区数据量之和；或者，

其中，逻辑信道组可以包含至少一个逻辑信道。
