Description

数据的传输方法和装置

背景技术
多址接入是无线通信物理层最核心的技术之一，它使得无线基站能区分且同时服务多个终端用户(User Equipment,UE),并减小其互相干扰(多址干扰)。无线通信系统大多采用简单的正交多址接入方式，即多个用户通过在不同维度上(频分、时分、码分等)正交划分资源来接入，如长期演进(Long Term Evolution，LTE)系统中采用的正交频分多址(Orthogonal Frequency Division Multiple Access，OFDMA)技术就是其中之一。
对于LTE系统，OFDMA的系统的设计中(如URLLC业务)，系统总时频资源被分成若干个部分，每个部分都是相互正交的时频资源区间。当需要传输上行数据时OFDMA用户设备可通过调度，半静态调度或者免授权传输等方式，为每个数据包选择相应的时频资源部分进行数据传输。
然而，使用OFDMA传输机制进行数据传输时，由于正交多址技术其可容纳的接入用户数与正交资源成正比，而正交资源数量受限于正交性要求，因此不能满足未来5G时代广域连续覆盖，热点高容量、海量连接、低延时接入等业务需求。

具体实施方式
本申请的技术方案可应用于5G等蜂窝通信系统中。图1为本申请提供的数据的传输方法的一种系统架构示意图，如图1所示，该系统架构中包括网络设备(例如图中的基站)以及用户设备，例如手机、通话平板等。上述架构中，网络设备为网络侧的基站或者其他能够提供基站功能的设备，为用户设备提供通信服务；特别地，在中文名称：设备到设备(Device-to-Device，D2D)通信中，网络设备还可以是承担基站功能的终端。除此之外，基站又称为无线接入网(Radio Access Network，RAN)设备，是一种将终端接入到无线网络的设备，上述架构中的基站还可以是全球移动通讯(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)中的演进型基站(Evolutional Node B，eNB或eNodeB)，或者中继站或接入点，或者5G网络中的基站等，在此并不限定。
本申请提供的数据的传输方法基于上述架构，能够支持上行非正交多址系统中，UE将多个数据包在同一时隙，相同时频资源上并行发送，从而提高时频资源利用率，节省包排队等待时间，增加潜在的最大重传次数，以适应将来更高速的数据交互需求。
图2为本申请提供的数据的传输方法实施例一的流程示意图，如图2所示，在图1所示的架构示意图的基础上，网络设备和用户设备之间的数据的传输方法具体包括以下步骤：
S101：用户设备获取用于对待发送的至少两个数据包进行多址接入的至少两个签名序列。
在本步骤中，用户设备需要向网络设备发送上行数据，例如需要发送多个数据包给网络设备，则可将该些数据包经过独立信道进行编码，可以分别来自与数据包个数相同的多个不同的传输块(Transport Block,TB)，也可以来自对同一个TB的不同分割，即需要多个用于多址接入的签名序列，分别对对应的数据包进行处理，因此用户需要先获取至少两个签名序列。该方案中，签名序列用于区分数据包在时频资源上所使用的数据层，签名序列可以为稀疏码多址接入(Sparse Code Multiple Access，SCMA)和偏振分割多路接入(Polarization Division Multiple Access，PDMA)中的码本，或基于多用户共享接入(Multi-User Shared Access，MUSA)中的扩频序列。
签名序列的具体获取方式至少包括以下几种：
第一种方式，用户设备从可用的签名序列中选择与数据包一一对应的签名序列。即用户设备自己选择得到上述需要的多个签名序列。
可选的，在该第一种获取签名序列的方式中，由于用户设备是自身获取的多个签名序 列，网络设备侧并不知道用户设备使用的具体签名序列，因此，UE需要将使用的多个签名序列通知网络设备，可通过向网络设备发送导频，导频的信息可以指示用户设备对多个数据包进行多址接入使用的多个签名序列，这里的导频的信息可以是偏移量或者索引等，以使网络设备可直接根据导频的信息确定用户设备使用的签名序列。
用户设备还可以通过控制信道向网络设备发送用于指示多个签名序列的控制信息，以使网络设备根据控制信息确定用户设备使用的签名序列。
第二种方式，用户设备向网络设备发送调度信息；调度信息用于指示用户设备需要上传数据，并指示用户设备待发送的数据量。例如可以通过数据调度请求和缓冲区状态报告等进行指示。网络设备接收用户设备发送的调度信息，并根据用户的调度信息进行调度处理，为用户设备调度带宽，并从可用签名序列中选择与用户设备要上传的多个数据包一一对应的签名序列，并通过调度确认消息返回给用户设备，调度确认消息用于指示所述至少两个签名序列，用户设备接收网络设备返回的调度确认消息，并根据所述调度确认消息确定至少两个签名序列。
S102：用户设备对至少两个数据包分别采用对应签名序列进行处理得到至少两个发送序列。
在本步骤中，用户设备对多个数据包由不同的传输块进行独立编码，然后分别采用对应的签名序列进行多址接入处理，得到多个数据层上的调制符号，即多个发送序列。
S103：用户设备将至少两个发送序列在同一时频资源上发送至网络设备。
在本步骤中，用户设备奖多个发送序列在同一个时频资源上进行传输，其含义是时域和频域均相同的资源上进行发送，即网络设备可在同一时频资源上检测接收到多个用户设备发送的发送序列。
S104：网络设备获取用户设备发送至少两个发送序列使用的至少两个签名序列。
在本步骤中，网络设备为了进行接收检测得到数据包，需要知道用户设备发送数据包使用的多个签名序列，具体的获取方式可以是：
第一种方式，网络设备接收所述用户设备发送的导频，并根据所述导频获取所述至少两个签名信序列；其中，所述导频的信息用于指示用户设备发送所述至少两个发送序列使用的至少两个签名序列。
第二种方式，网络设备接收所述用户设备通过控制信道发送的用于指示所述至少两个签名序列的控制信息，并根据所述控制信息获取所述至少两个签名序列。
第三种方式，网络设备在接收到多个发送序列之前，网络设备接收用户设备发送的调度信息，调度信息用于指示用户设备需要上传数据，并指示用户设备待发送的数据量。网络设备根据调度信息为用户设备调度带宽，并从可用签名序列中选择与所述数据量指示的数据包一一对应的签名序列，并将选择的多个签名序列通过调度确认信息返回给用户设备。
S105：网络设备根据每个签名序列对对应的发送序列分别进行检测，获取至少两个数据包。
在本步骤中，网络设备根据获取到的多个签名序列，对接收到的多个发送序列分别进行接收检测，得到用户设备发送的多个数据包。
在上述方案中，用户设备发送的多个数据包中，用户设备同时频资源发送的多个数据包可以是每个数据包的初传包，也可以是一些数据包的初传包和另一些数据包的重传包， 也可全部是数据包的重传包，且每个数据包的重传次数可不相同，对此本申请均不做限制。
以两个数据包为例，该多个数据包包括：第一数据包的初传包和第二数据包的初传包；或者，第一数据包的初传包和第二数据包的重传包；或者，第一数据包的重传包和第二数据包的重传包。并且在存在多个重传包时，每个数据包的重传次数可以不相同。
本实施例提供的数据的传输方法，用户设备获取用于对待发送的至少两个数据包进行多址接入的至少两个签名序列，然后对至少两个数据包分别采用对应签名序列进行处理得到至少两个发送序列，再将所述至少两个发送序列在同一时频资源上发送至网络设备。网络设备接收到用户设备发送的至少两个发送序列之后，获取用户设备发送至少两个发送序列使用的至少两个签名序列，并根据每个签名序列对对应的发送序列分别进行检测，获取至少两个数据包，用户设备可将多个数据包在同一个时隙同一个时频资源上进行传输，从而提高时频资源利用率，节省包排队时间，提高数据传输效率。
在上述实施例的基础上，下面以基站为例，列举了一些典型的数据包在同一时频资源上并行传输的流程，以及标准中可能的体现形式等，对本申请提供的数据的传输方法进行说明。
图3为本申请提供的数据的发送方法的一实例的传输示意图，如图3所示，本方案中，假设上行Grant-free SCMA非正交传输系统(也可以是其他形式的非正交传输方式)中，用户设备(User Equipment，UE)在某一时刻有2个待传输的初传数据包，由不同的TB经过独立的信道编码得到，分别表示为CB 1 (0)和CB 2 (0)，其中上标0表示两个数据包都是初传包。UE根据本次数据包个数，选择对应传输模式，此传输模式对应签名序列集{s 1,s 2}，用于对CB 1 (0)和CB 2 (0)进行SCMA多址接入处理，得到2个数据层上的发送序列，并在同一时频资源上同时传输至基站。
在上述过程中，引入传输模式的概念，不同的传输模式对应不同的签名序列集，因此在指示多个签名序列时，可以直接指示传输模式，可确定出对应的签名序列集，从而得到需要的多个签名序列。UE可通过一个导频p将所选传输模式告知BS，其中导频的信息和传输模式的对应关系由基站(Base Station，BS)和UE事先约定。BS根据解到的导频p的信息，并根据约定好的p的信息与传输模式对应关系，从而知道该UE是将两个包通过两个数据层(分别使用签名序列s 1,s 2)来传输的，从而进行相应的接收检测。
可选的UE还可以通过控制信息将所选传输模式告知基站，而不必建立导频和传输模式(签名序列或签名序列集)的映射关系。
图4为本申请提供的数据的发送方法的另一实例的传输示意图，如图4所示，本方案中，假设上行Grant-free SCMA非正交传输系统中，UE在某一时刻有3个待传输的包，由不同的TB经过独立的信道编码得到，分别表示为CB 1 (0)，CB 2 (1)和CB 3 (2)。其中CB 1 (0)是数据包1的初传包，CB 2 (1)是数据包2的第一次重传包，CB 3 (2)是数据包3的第二次重传包。UE根据本次数据包个数，同样的可选择对应传输模式，此传输模式对应签名序列集{s 1，s 2，s 3}，用于对CB 1 (0)，CB 2 (1)和CB 3 (2)进行SCMA多址接入处理，得到3个数据层上的发送序列，并在同一时频资源上同时传输。
UE可通过一个导频p将所选传输模式告知BS，其中导频和传输模式的对应关系由BS和UE事先约定。基站根据解到的导频p的信息，并根据约定好的p的信息与传输模式对应关系，从而知道该UE是将3个包通过3个数据层(分别使用签名序列s 1,s 2,s 3) 来传输的，从而进行相应的接收检测。
UE还可以通过控制信息将所选传输模式告知基站，而不必建立导频和传输模式(签名序列或签名序列集)的映射关系。
可选的，本方案的另一种具体实现中，假设上行授权传输(grant-based)SCMA系统中，UE在某一时刻有2个待传输的数据包，分别表示为CB 1 (1)和CB 2 (2)，分别是包1的第一次重传包和包2的第二次重传包。UE通过调度请求(Scheduling Request,SR)指示有上行传输数据，并通过缓冲区状态报告(Buffer Status Reporting,BSR)告知基站本次传输的数据量。基站根据BSR为UE调度所需带宽，并告知其传输模式。UE在调度的带宽内根据传输模式，将CB 1 (1)和CB 2 (2)分别用所对应的两个签名序列(s 1和s 2)进行多址接入处理，并在两个数据层上同时发送。
BS已知该用户上行传输所使用的传输模式，可直接对各数据层上传输的数据包进行接收检测。
图5为本申请提供的数据的发送方法的又一实例的传输示意图；如图5所示，假设上行Grant-free SCMA非正交传输系统中，UE在某一时刻有2个待传输的初传数据包，由同一TB拆分并经过独立的信道编码得到，分别表示为CB 1 (0)和CB 2 (0)，其中上标0表示两个包都是初传的包。UE根据本次数据包个数，选择对应传输模式，此传输模式对应签名序列集{s 1,s 2}，用于对CB 1 (0)和CB 2 (0)进行SCMA多址接入处理，得到2个数据层上的发送序列，并在同一时频资源上同时传输。
在本实例中，与前述方案同样的，UE可通过一个导频p将所选传输模式告知BS，其中导频和传输模式的对应关系由BS和UE事先约定。BS根据解到的导频p，并根据约定好的p与传输模式对应关系，从而知道该UE是将两个数据包通过两个数据层(分别使用签名序列s 1,s 2)来传输的，从而进行相应的接收检测。
UE还可以通过控制信息将所选传输模式告知基站，而不必建立导频和传输模式(签名序列或签名序列集)的映射关系。
根据上述实施例可知，在本方案的具体实现中，CB 1和CB 2可以来自同一个TB，也可以来自于不同的TB，对此本方案不做限制。
图6为本申请提供的数据的发送方法的再一实例的传输示意图；如图6所示，该方案中，假设上行Grant-free MUSA非正交传输系统中，UE在某一时刻有2个待传输的数据包，分别由不同TB并经过独立的信道编码得到，表示为CB 1 (1)和CB 2 (2)，分别是数据包1的第一次重传包和数据包2的第二次重传包。UE根据本次传输包个数，选择对应传输模式，此传输模式对应MUSA签名序列集{s 1,s 2}，用于对CB 1 (1)和CB 2 (2)进行MUSA多址接入处理，得到2个数据层上的发送序列，并在同一时频资源上同时传输。
同样的，UE可通过一个导频p将所选传输模式告知BS，其中导频的信息和传输模式的对应关系由BS和UE事先约定。BS根据解到的导频p，并根据约定好的p的信息与传输模式对应关系，从而知道该UE是将两个包通过两个数据层(分别使用签名序列s 1,s 2)来传输的，从而进行相应的接收检测。UE还可以通过控制信息将所选传输模式告知基站，而不必建立导频和传输模式(签名序列或签名序列集)的映射关系。
除了上述方案，本申请还提供一种数据的传输方案，假设上行Grant-free SCMA非正交传输系统中，UE在某一时刻有2个待传输的初传数据包，由不同的TB经过独立的信 道编码得到，分别表示为CB 1 (0)和CB 2 (0)，都是初传数据包。UE根据本次传输包个数，选择对应传输模式，此传输模式对应签名序列集
Figure PCTCN2018072671-appb-000001
用于对CB 1 (0)和CB 2 (0)进行SCMA多址接入处理，得到2个数据层上的发送序列，并在同一时频资源上同时传输。其中
Figure PCTCN2018072671-appb-000002
为对原始签名序列s 1,s 2进行处理结果，处理过程包括相位旋转和功率分配等方式。
UE可通过一个导频p将所选传输模式告知BS，其中导频和传输模式的对应关系由BS和UE事先约定。BS根据解到的导频p，并根据约定好的p与传输模式对应关系，从而知道该UE是将两个包通过两个数据层(分别使用签名序列
Figure PCTCN2018072671-appb-000003
)来传输的，从而进行相应的接收检测。UE还可以通过控制信息将所选传输模式告知基站，而不必建立导频和传输模式(签名序列或签名序列集)的映射关系。
同样的在该实现方式中，CB 1和CB 2可以来自同一个TB，也可以来自于不同的TB，对此本方案不做限制。
上述任一实现方式提供的数据的传输方法，能够支持上行非正交多止系统中，UE将多个数据包经过独立的信道编码，分别使用不同的签名序列进行多址接入处理得到发送序列，在同一个时隙，同一个时频资源上并行发送给基站，能够有效的提高时频资源利用率，减少包排队等待时间，增加潜在的最大重传次数，提高传输效率和可靠性。
