Description

传输数据的方法和装置 技术领域
本申请实施例涉及通信领域，并且更具体地，涉及通信领域中传输数据的方法和装置。
背景技术
未来的网络系统会引入非授权(grant free、grant-free、grantless或without grant)模式传输数据，非授权模式为网络设备给终端设备划分非授权传输区域，终端设备采用非授权传输区域中的传输资源发送上行数据，不需要终端设备通过请求来实现上行数据的传输，可以降低时延，并且有助于节省信令开销。
但是，终端设备在采用非授权传输区域中的传输资源发送上行数据时，不同的终端设备可能会选择相同的传输资源，导致不同终端设备之间产生冲突，例如，多个终端设备可能会在非授权传输区域中选择完全相同或部分重叠的传输资源，导致冲突的概率较高，进而数据传输的失败的概率也较高，使得数据传输的可靠性降低。
发明内容
本申请实施例提供了一种传输数据的方法和装置，有利于提高传输数据的可靠性。
第一方面，提供了一种传输数据的方法，包括：网络设备在第一查询区域向终端设备发送第一指示信息，所述第一指示信息用于指示所述第一查询区域对应的非授权传输区域中的传输资源的分配情况；所述网络设备在所述第一查询区域对应的非授权传输区域接收所述终端设备根据所述第一指示信息发送的数据。
在本申请实施例中，网络设备向终端设备发送第一指示信息，终端设备根据第一指示信息指示的非授权传输区域中的传输资源的分配情况确定发送数据的可以使用的传输资源，而不是直接随机的选择非授权传输区域中的传输资源，有助于降低不同终端设备之间冲突的概率，也能够降低数据传输失败的概率，有利于提高传输数据的可靠性。
更具体地，当终端设备工作在非授权模式下时，重传的终端设备可以根据第一指示信息在预分配的传输资源内发送重传的数据，初传的终端设备在未分配的传输资源内发送初传数据，这样，可以降低重传的终端设备与初传的终端设备之间的冲突，进而提高传输数据的可靠性。可选地，第一指示信息可以指示重传的第一终端设备采用非授权传输区域中的第一传输资源传输重传数据，第一指示信息可以指示重传的第二终端设备采用非授权传输区域中的第二传输资源传输重传数据，第一终端设备与第二终端设备不同，第一传输资源与第二传输资源不同，这样可以降低重传的终端设备之间的传输数据的冲突，可以提高传输数据的可靠性。
可选地，网络设备可以向一个或多个终端设备发送所述第一指示信息，也即是所述一个或多个终端设备包括所述终端设备，在本申请实施例中，避免赘述，仅以一个终端设备为例进行描述。

在本申请实施例中，重传的终端设备在预分配的传输资源上发送重传数据，初传的终端设备在未分配的传输资源上发送初传数据，这样，初传的终端设备和重传的终端设备就不会选择相同的传输资源，可以避免重传的终端设备与初传的终端设备之间的冲突或碰撞，有利于提高传输数据的可靠性。
可选地，所述网络设备在所述第一查询区域对应的非授权传输区域接收所述终端设备根据所述第一指示信息发送的数据，包括：所述网络设备在所述第一查询区域对应的非授权传输区域预分配的传输资源上接收所述终端设备以第一概率发送的重传数据；所述网络设备在所述第一查询区域对应的非授权传输区域的未分配的传输资源上接收所述终端设备以第二概率发送的重传数据，所述第一概率大于所述第二概率，所述第一概率与所述第二概率之和为1，这样，即终端设备向网络设备发送重传数据时，选择预分配的 传输资源的概率要大于未分配的传输资源的概率，这样，未分配的传输资源可以被用来传输初传数据，在一定程度上，可以降低初传终端设备与重传终端设备之间的碰撞，可以提高传输数据的可靠性。

可选地，第一非授权传输区域与第二非授权传输区域不同，具体地，第一非授权传输区域在时域上属于第二非授权传输区域之前的非授权传输区域，终端设备可以在第一非授权传输区域的未分配的传输资源上发送控制部分，并且终端设备在时域上后面的第二非授权传输区域根据控制部分发送数据部分。
在某些实现方式中，所述第一查询区域为ACK区域，所述第一指示信息还用于指示第三非授权传输区域的数据是否被成功接收，所述第三非授权传输区域时域上在所述第一查询区域对应的非授权传输区域的前面，所述第一查询区域对应的非授权传输区域在时域上在所述第一查询区域的后面。
在本申请实施例中，第一查询区域可以是现有技术中的ACK区域，ACK区域的指示信息本身可以指示数据是否被成功接收的同时可以指示ACK区域对应的非授权传输区域中的传输资源的分配情况，避免第一查询区域占用新的传输资源，可以节省资源开销。

更具体地，当终端设备工作在非授权工作模式下时，重传的终端设备可以根据第一指示信息在预分配的传输资源内发送重传的数据，初传的终端设备在未分配的传输资源内发送初传数据，这样，可以降低重传的终端设备与初传的终端设备之间的冲突，进而提高传输数据的可靠性。可选地，第一指示信息可以指示重传的第一终端设备采用非授权传输区域中的第一部分传输资源传输重传数据，第一指示信息可以指示重传的第二终端设备采用非授权传输区域中的第二部分传输资源传输重传数据，第一终端设备与第二终端设备不同，第一部分传输资源与第二部分传输资源不同，这样可以降低重传的终端设备之间的传输数据的冲突，提高传输数据的可靠性。若所述终端设备为第一终端设备，则所述终端设备采用第一部分传输资源传输重传数据，若所述终端设备为第二终端设备，则所述终端设备采用第二部分传输资源传输重传数据，这样，可以避免重传的终端设备之间的冲突，从而能够提高传输数据的可靠性。

在本申请实施例中，重传的终端设备在预分配的传输资源上发送重传数据，初传的终端设备在未分配的传输资源上发送初传数据，这样，初传的终端设备和重传的终端设备就不会选择相同的传输资源，可以避免重传的终端设备与初传的终端设备之间的冲突或碰撞，有助于数据可靠的传输。

具体实施方式
应理解，本申请实施例的技术方案可以应用于各种通信系统，例如：全球移动通讯(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)、全球互联微波接入(worldwide interoperability for microwave access，WiMAX)通信系统、无线局域网(wireless local area network，WLAN)或未来第五代无线通信系统(the fifth Generation，5G)等。
图1示出了本申请实施例应用的通信系统100。该通信系统100可以包括终端设备110和终端设备120，终端设备110和终端设备120可以指接入终端、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，5G网络中的终端等。
网络设备130，可以是与所述终端设备110和所述终端设备120进行无线通信的网络侧设备，例如，无线保真(wireless-fidelity，Wi-Fi)的接入点、下一代通信的基站，如5G的gNB或小站、微站，传输接收点(transmission reception point，TRP)，也可以是2G、3G和4G中的基站，还可以是中继站、接入点、车载设备、可穿戴设备等。
在现有技术中，终端设备110和终端设备120同时在非授权传输区域发送上行数据时，可能会选择相同或部分重叠的传输资源(例如，图1中灰色方框)，这样，终端设备110和终端设备120就会发生碰撞，导致数据传输的失败，本申请实施例中网络设备可以指示终端设备非授权传输区域中传输资源的使用情况，例如，非授权传输区域中的部分传输资源预分配为传输重传数据的传输资源，除了预分配为传输重传数据的传输资源之外的传输资源为传输初传数据的传输资源；又例如，非授权传输区域中的部分传输资源预分配为传输数据部分的传输资源，除了预分配为传输数据部分的传输资源之外的传输资源为传输控制部分的传输资源，这样，终端设备根据非授权传输区域中的传输资源使用情况来确定传输数据的传输资源，可以减少不同终端设备之间的冲突，有利于提高传输数据的可靠性。
在本申请实施例中，传输资源可以包括但不限于如下传输资源的一种或多种的组合：时域资源，如无线帧、子帧、符号等；频域资源，如子载波、资源块等；空域资源，如发送天线、波束等；码域资源，如稀疏码多址接入(sparse code multiple access，SCMA)码本组、低密度签名(low density signature，LDS)组、CDMA码组等；上行导频资源； 当然，传输资源也可以包括其他的传输资源，例如，功率域或图样等，本申请实施例对此不作限定。
在本申请实施例中，如上的传输资源可以根据包括但不限于以下控制机制进行传输：上行功率控制，如上行发送功率上限控制等；调制编码方式设置，如传输块大小、码率、调制阶数设置等；重传机制，例如混合自动重传请求(Hybrid Automatic Repeat Request，HARQ)等。
在本申请实施例中，查询区域与非授权传输区域之间的映射关系可以是一一对应，也可以是一个查询区域对应多个非授权传输区域，也可以是多个查询区域对应一个非授权传输区域，例如，可以是图2所示的一个查询区域对应一个非授权传输区域，查询区域1对应非授权传输区域1，查询区域2对应非授权传输区域2，查询区域3对应非授权传输区域3。又例如，也可以是图3中的一个查询区域对应多个非授权传输区域，查询区域1对应非授权传输区域1、非授权传输区域2和非授权传输区域3，本申请实施例对此不作任何限制。
为了解决未来网络mMTC类业务，以及满足低时延、高可靠的业务传输，系统100中的网络设备130可以采用非授权传输方案，该方案可以适用于上行数据传输。在该非授权传输机制中，终端设备无需通过调度请求方式请求网络设备分配传输资源，而是直接竞争传输资源并进行上行数据的传输，从而可以减少系统信令开销并且降低传输时延。非授权传输可以理解为如下含义中的任意一种或多种含义，或者理解为多种含义中的部分技术特征的组合：
1、非授权传输可以指：网络设备预先分配并告知终端设备非授权传输区域；终端设备有上行数据传输需求时，从网络设备预先分配的非授权传输区域中选择至少一个传输资源，使用所选择的传输资源发送上行数据；网络设备在该预先分配的非授权传输区域中的至少一个传输资源上检测终端设备发送的上行数据。该检测可以是盲检测，也可能根据上行数据中某一个控制域进行检测，或者是其他方式进行检测。
该盲检测可以理解为在不预知是否有数据到达的情况下，对可能到达的数据进行的检测。该盲检测也可以理解为没有显式的信令指示下的检测。
2、非授权传输可以指：网络设备预先分配并告知终端设备非授权传输区域，以使终端设备有上行数据传输需求时，从网络设备预先分配的非授权传输区域中随机选择至少一个传输资源，并使用所选择的传输资源发送上行数据。
3、非授权传输可以指：不需要网络设备动态调度即可实现终端设备的上行数据传输的方法，该动态调度可以是指终端设备每次进行上行数据传输的传输资源都需要网络设备通过信令进行指示的一种调度方式。可选地，该传输资源可以是终端设备接收到该信令的时刻以后的一个或多个传输时间单位的传输资源。一个传输时间单位可以是指一次传输的最小时间单元，比如传输时间间隔(transmission time interval，TTI)，数值可以为1ms,或者可以是预先设定的传输时间单元。可选地，实现终端设备的上行数据传输可以理解为允许两个或两个以上终端设备的数据在相同的时频资源上进行上行数据传输。
4、非授权传输可以指：终端设备在不需要网络设备授权的情况下进行上行数据传输。该授权可以指终端设备向网络设备发送上行调度请求，网络设备在接收到该调度请求之后，向该终端设备发送上行授权(UL grant)，其中该上行授权用于指示为终端设备分配的上行传输资源。
5、非授权传输可以指：一种竞争传输方式，具体地可以指多个终端设备在预先分配的相同的时频资源上同时进行上行数据传输，而无需网络设备进行授权。
可选地，上述数据可以为包括数据部分或者控制部分。
图4示出了本申请实施例的通信方法200，该方法200可以应用于图1所示的通信系统100，但本申请实施例不限于此。
S210，网络设备在第一查询区域向终端设备发送第一指示信息，所述第一指示信息用于指示所述第一查询区域对应的非授权传输区域中的传输资源的分配情况。
可选地，非授权传输区域中的传输资源的分配情况可以为非授权传输区域中哪些传输资源被预分配，或者非授权传输区域中哪些传输资源没有被分配，即非授权传输区域中的传输资源由预分配的传输资源和未分配的传输资源组成。该预分配的传输资源可以是分配的用来重传数据的传输资源，或者是分配的用来传输数据部分的传输资源。
作为一个可选实施例，在S210之前，所述方法还包括：所述网络设备向所述终端设备发送第二指示信息，所述终端设备接收网络设备发送的第二指示信息，所述第二指示信息用于指示一个或多个查询区域所在的传输资源位置和/或所述一个或多个查询区域与一个或多个非授权传输区域之间的映射关系，所述一个或多个查询区域包括所述第一查询区域，所述一个或多个非授权传输区域包括所述第一查询区域对应的非授权传输区域；所述终端设备根据所述第二指示信息指示的第一查询区域所在的传输资源位置确定所述第一查询区域。可选地，网络设备可以通过一个指示信息来指示一个或多个查询区域所在的传输资源位置与所述映射关系，网络设备也可以通过两个不同的指示信息来指示一个或多个查询区域所在的传输资源位置和所述映射关系，例如所述第二指示信息指示所述映射关系，第三指示信息指示所述一个或多个查询区域所在的传输资源位置。可选地，第二指示信息可以指示一个或多个查询区域所在的传输资源位置，一个或多个非授权传输区域所在的传输资源位置，以及所述一个或多个查询区域与所述第一或多个非授权传输区域之间的映射关系；或者是网络设备可以通过至少一个指示信息指示所述一个或多个查询区域所在的传输资源位置，一个或多个非授权传输区域所在的传输资源位置，以及所述一个或多个查询区域与所述第一或多个非授权传输区域之间的映射关系，所述至少一个指示信息包括所述第一指示信息，本申请实施例对此不作任何限制。
具体而言，网络设备可以向终端设备发送第二指示信息，终端设备根据该第二指示信息确定一个或多个查询区域所在的传输资源位置，当所述终端设备移动到一个或多个查询区域中的第一查询区域所在传输资源位置时，根据所述映射关系确定第一查询区域对应的非授权传输区域，然后根据第一指示信息指示第一查询区域对应的非授权传输区域中的传输资源的分配情况确定发送数据的传输资源。
应理解，所述一个或多个查询区域用于网络设备发送第一指示信息，也用于终端设备接收第一指示信息，该一个或多个查询区域的所在传输资源可以通过网络设备确定，每个查询区域都存在对应的非授权传输区域。
作为一个可选实施例，所述网络设备向所述终端设备发送第二指示信息，可以包括：所述网络设备通过广播消息或多播消息向至少一个终端设备发送第二指示信息，至少一个终端设备包括所述终端设备。相应的，所述终端设备接收网络设备发送的第二指示信息，包括：所述终端设备接收所述网络设备通过广播消息或多播消息发送的第二指示信息。
作为一个可选实施例，S210包括：当所述网络设备没有成功接收到所述终端设备发送的数据时，但所述网络设备能够识别出发送没有成功接收到的数据的发送端为所述终端设备，所述网络设备在所述第一查询区域向所述终端设备发送所述第一指示信息，即在有终端设备需要重传时，网络设备可以为有需要重传的终端设备预分配传输资源。当然，网络设备发送第一指示信息的时机也可以是周期性的发送，并不限定在没有成功接收到所述终端设备发送的数据时再发送第一指示信息；或者是该第一指示信息也可以不发送，表示第一查询区域对应的非授权传输区域中的任何传输资源都没有被分配，第一查询区域对应的非授权传输区域中的传输资源都可以用来传输初传数据。
作为一个可选实施例，S210，包括：所述网络设备通过系统信息块SIB消息或广播消息或多播消息在所述第一查询区域向所述终端设备发送所述第一指示信息。终端设备接收网络设备通过SIB消息或广播消息或多播消息在所述第一查询区域发送的所述第一指示信息。
S220，终端设备在第一查询区域接收网络设备发送的第一指示信息，所述终端设备根据所述第一指示信息在所述第一查询区域对应的非授权传输区域中确定发送数据所采用的第一传输资源。
作为一个可选实施例，所述第一查询区域为肯定应答/或否定应答(acknowledge/negative acknowledge，ACK/NACK)区域，在本申请实施例中，为了方便描述将肯定应答/或否定应答区域简称为“ACK区域”，所述第一指示信息还用于指示第三非授权传输区域的数据是否被成功接收，所述第三非授权传输区域时域上在所述第一查询区域对应的非授权传输区域的前面，所述第一查询区域对应的非授权传输区域在时域上在所述第一查询区域的后面；S220，包括：所述终端设备根据所述第一指示信息确定所述第三非授权传输区域的数据是否被成功接收以及根据所述第一查询区域对应的非授权传输区域中的传输资源分配情况确定所述第一传输资源。
作为一个可选实施例，所述第一指示信息具体用于指示所述ACK区域第一位置对应的第三非授权传输区域第二位置的数据被成功接收和用于指示所述第一位置对应第三位置的传输资源未分配，所述第三位置为所述第一查询区域对应的非授权传输区域中的传输资源位置；或者所述第一指示信息具体还用于指示所述第二位置的数据没有被成功接收和用于指示所述第三位置的传输资源已被预分配。
具体地，第一查询区域为ACK区域时，不需要网络设备在分配一块新的传输资源作为查询区域的传输资源位置，而是利用现有的ACK作为查询区域的位置，例如，ACK区域中第一位置为0时表示第三非授权传输区域第二位置上的数据没有被成功接收，则第二位置上的数据需要进行重传，该第一位置的0也表示与第一位置对应的第一查询区域对应的非授权区域中的第三位置的传输资源被预分配，用来重传第三非授权传输区域第二位置没有被成功接收的数据；ACK区域中第一位置为1时表示第二位置上的数据被成功接收，则第二位置上的数据不需要进行重传，该第一位置的1也表示第三位置的传输资源未分配，即传输数据成功了，不需要分配传输资源来重传数据，该第三位置的传输资源可以传输初传的数据，这样，可以节省资源开销，提高资源的使用效率。
作为一个可选实施例，第一指示信息具体还用于指示所述第二位置的数据没有被成功接收、用于指示所述第三位置的传输资源已被预分配以及预分配了第三位置的传输资源的终端设备的数量。例如，第一位置为2时，表示第二位置上2个终端设备的数据没 有被成功接收，并且该第二位置对应的第三位置的传输资源被2个终端设备被预分配，具体地，不同的终端设备在相同的预分配的传输资源上发送数据可以通过多址技术来实现。
S230，所述终端设备在所述第一传输资源上向所述网络设备发送数据，所述网络设备在所述第一查询区域对应的非授权传输区域接收所述终端设备根据所述第一指示信息发送的数据。
作为一个可选实施例，所述第一指示信息具体用于指示所述第一查询区域对应的非授权传输区域中预分配的传输资源或未分配的传输资源，例如，图5中第一指示信息指示查询区域2对应的非授权传输区域2中的资源块1、资源块3和资源块9被预分配。具体地，S220包括：当第一指示信息用于指示预分配的传输资源时，终端设备可以将预分配的传输资源确定为重传数据的传输资源，或者是确定为传输数据部分的传输资源，终端设备将第一查询区域对应的非授权传输区域中除了预分配的传输资源外的传输资源确定未分配的传输资源，终端设备将未分配的传输资源确定为初传数据的传输资源，或者确定为传输控制部分的传输资源；当第一指示信息用于指示未分配的传输资源时，终端设备可以将未分配的传输资源确定为初传数据的传输资源，或者确定为传输控制部分的传输资源，终端设备将第一查询区域对应的非授权传输区域中除了未分配的传输资源外的传输资源确定为预分配的传输资源，终端设备将预分配的传输资源确定为重传数据的传输资源，或者确定为传输数据部分的传输资源，其中，所述数据包括所述控制部分和/或所述数据部分；第一指示信息指示可以指示第一查询区域对应的非授权传输区域中预分配的传输资源和未分配的传输资源，例如，第一查询区域对应的非授权传输区域分为9个资源块，用9bits指示位＝[100110011]指示9个资源快，1表示预分配使用的资源块，0表示未分配使用的资源块。
第一下面通过举例说明，S220如何确定第一传输资源，S230如何在第一传输资源上发送数据。
第一个例子，S220，包括：所述终端设备根据所述第一指示信息在所述第一查询区域对应的非授权传输区域中确定预分配的传输资源，并将所述预分配的传输资源确定为所述第一传输资源；S230，包括：所述终端设备在所述第一传输资源上向所述网络设备发送重传数据；网络设备接收终端设备在第一传输资源(所述第一查询区域对应的非授权传输区域预分配的传输资源)上发送的重传数据。
可选地，终端设备以第一概率在所述第一查询区域对应的非授权传输区域预分配的传输资源上向网络设备发送重传数据；终端设备以第二概率在所述第一查询区域对应的非授权传输区域未分配的传输资源上向网络设备发送重传数据，第一概率大于第二概率，即终端设备在发送重传数据时，选择预分配的传输资源的概率要大于未分配的传输资源的概率。
第二个例子，S220，包括：所述终端设备根据所述第一指示信息在所述第一查询区域对应的非授权传输区域中确定未分配的传输资源，并将未分配的传输资源确定为所述第一传输资源；S230，包括：所述终端设备在所述第一传输资源上向所述网络设备发送初传数据；网络设备接收所述终端设备在第一传输资源(所述第一查询区域对应的非授权传输区域未分配的传输资源)上发送的初传数据。
可选地，终端设备以第三概率在所述第一查询区域对应的非授权传输区域未分配的 传输资源上向网络设备发送初传数据；终端设备以第四概率在所述第一查询区域对应的非授权传输区域被预分配的传输资源上向网络设备发送初传数据，第三概率大于第四概率，即终端设备在发送初传数据时，选择未分配的传输资源的概率要大于预分配的传输资源的概率，这样，可以避免初传的终端设备与重传的终端设备之间的冲突，从而可以提高传输数据的可靠性。进一步地，第一概率大于第四概率，第三概率大于第二概率，第一概率与第二概率之和为1，第三概率与第四概率之和为1。
在本申请实施例中，初传的终端设备采用未分配的传输资源，重传的终端设备采用预分配的传输资源，这样，可以降低初传的终端设备与重传的终端设备之间的冲突，提高传输数据的可靠性。
第三个例子，S220，包括：所述终端设备根据所述第一指示信息在所述第一查询区域对应的非授权传输区域中确定未分配的传输资源，并将所述未分配的传输资源确定为所述第一传输资源；S230，包括：所述终端设备在所述第一传输资源上向所述网络设备发送控制部分；网络设备接收所述终端设备在所述第一传输资源(所述第一查询区域对应的非授权传输区域未分配的传输资源)发送的控制部分，其中，所述数据包括所述控制部分和/或所述数据部分。
可选地，终端设备以第五概率在所述第一查询区域对应的非授权传输区域未分配的传输资源上向网络设备发送控制部分；终端设备以第六概率在所述第一查询区域对应的非授权传输区域预分配的传输资源上向网络设备发送控制部分，第五概率大于第六概率，即终端设备在发送控制部分时，选择未分配的传输资源的概率要大于预分配的传输资源的概率，这样，可以避免控制部分与数据部分之间的冲突，从而可以提高传输数据的可靠性。
第四个例子，S220，包括：所述终端设备根据所述第一指示信息在所述第一查询区域对应的非授权传输区域中确定预分配的传输资源，并将所述预分配的传输资源确定为所述第一传输资源；S230，包括：所述终端设备在所述第一传输资源上根据所述控制部分向所述网络设备发送数据部分；所述网络设备接收所述终端设备在所述第一传输资源(所述第一查询区域对应的非授权传输区域预分配的传输资源)发送的数据部分，其中，所述数据包括所述控制部分和/或所述数据部分。
可选地，终端设备以第七概率在所述第一查询区域对应的非授权传输区域预分配的传输资源上向网络设备发送数据部分；终端设备以第八概率在所述第一查询区域对应的非授权传输区域未分配的传输资源上向网络设备发送数据部分，第七概率大于第八概率，即终端设备在发送数据部分时，选择预分配的传输资源的概率要大于未分配的传输资源的概率。第五概率与第六概率之和为1，第七概率与第八概率之和为1。
可选地，上述四个例子中，终端设备向网络设备发送初传数据时，网络设备在第一查询区域对应的非授权传输区域的未分配的传输资源上检测终端设备发送的数据，例如，可以是盲检；终端设备向网络设备发送重传数据时，网络设备在第一查询区域对应的非授权传输区域的预分配的传输资源上检测终端设备发送的数据，例如，可以是盲检，更具体地，第一指示信息指示哪些重传的终端设备用预分配的哪些传输资源时，网络设备可以在特定的预分配的传输资源上检测特定的终端设备发送的重传数据。换句话说，网络设备发送的第一指示信息指示的是多个终端设备重传采用多个传输资源时，网络设备在该多个传输资源内盲检数据，当第一指示信息指示的是特定终端设备采用特定的传输 资源时，网络设备直接在特定的传输资源上检测数据。
作为一个可选实施例，在S210之前，网络设备可以配置非授权传输区域，例如，所述网络设备向至少一个终端设备发送传输区域配置信息，所述至少一个终端设备包括所述终端设备，所述传输区域配置信息用于指示海量物联网通信(massive machine type communication，mMTC)类型的终端设备采用一个或多个查询区域对应的一个或多个非授权传输区域传输数据和低时延高可靠通信(ultra-reliable and low latency communications，URLLC)类型的终端设备在初传失败时采用一个或多个查询区域对应的一个或多个非授权传输区域传输数据。
可选地，所述网络设备可以通过广播消息或多播消息向小区所在的所有的终端设备广播传输区域配置信息，mMTC类型的终端设备采用本申请实施例中的一个或多个非授权传输区域传输数据，URLLC类型的终端设备采用现有技术的非授权传输区域传输数据，当URLLC类型的终端设备在现有技术的非授权传输区域初传失败时切换到本申请实施例中的一个或多个非授权传输区域，来提高传输数据的可靠性。
图6示出了本申请实施例提供的另一传输数据的方法300，包括：
S310，网络设备向终端设备发送第二指示信息，所述第二指示信息用于指示一个或多个查询区域所在的传输资源位置以及所述一个或多个查询区域与一个或多个非授权传输区域之间的映射关系。
可选地，在S310之前，所述方法还包括，所述网络设备确定一个或多个查询区域所在的传输资源位置以及所述一个或多个查询区域与一个或多个非授权传输区域之间的映射关系。
S320，终端设备接收网络设备发送的第二指示信息，所述终端设备根据所述第二指示信息确定所述一个或多个查询区域的传输资源位置以及所述一个或多个查询区域中第一查询区域对应的非授权传输区域。
作为一个可选实施例，S310之后，所述方法还包括：所述网络设备在所述一个或多个查询区域中的第一查询区域向所述终端设备发送第一指示信息，所述第一指示信息用于指示所述第一查询区域对应的非授权传输区域中的传输资源的分配情况；所述网络设备在所述第一查询区域对应的非授权传输区域接收所述终端设备根据所述第一指示信息发送的数据。
下面举例说明本申请实施例提供的传输数据的方法：
例如，图7示出了本申请实施例提供的方法400，包括：
S410，第一设备(如前述的网络设备)确定至少一个非授权传输区域，所述非授权传输区域用于上行非授权数据传输，至少一个非授权传输区域至少可以包括时频域的传输资源，如图2所示的非授权传输区域1-非授权传输区域3。所述非授权传输区域还可以包括时频域以外的传输资源，如码域、功率域、图样等，以适用于多种不同的多址技术，这里不再一一赘述。在S310中的至少一个非授权传输区域包括前述方法200和方法300中第一查询区域对应的非授权传输区域。
S420，第一设备确定至少一个非授权传输(前述的一个或多个非授权传输区域)对应的至少一个查询区域(前述的一个或多个查询区域)，以及该至少一个查询区域与至少一个非授权传输区域的映射关系。所述至少一个查询区域中所发送的前述的第一指示信息用于指示与其相映射的非授权传输区域中预分配使用的传输资源。如图5所示，查 询区域1-查询区域3与非授权传输区域1-非授权传输区域3分别映射，第一设备在查询区域2发送第一指示信息用于指示非授权传输区域2中预分配的传输资源，如资源块1、资源块3、和资源块9预分配使用。所述至少一个查询区域与所示至少一个非授权传输区域的映射关系可以为一一对应，即一个查询区域对应一个非授权传输区域；所述映射关系也可以为一对多，即一个查询区域对应多个非授权传输区域；所述映射关系还可以为多对一，即多个查询区域对应一个非授权传输区域。需要说明的是，每个查询区域至少可以映射一个非授权传输区域，而第一设备在S310中确认的一个或多个非授权传输区域中，可以有部分非授权传输区域无需与任何查询区域相映射，也即为现有技术的非授权传输区域。
S430、第一设备向至少一个第二设备(第二设备可以为前述终端设备)下发第一消息，所述第一消息包括第二指示信息，第二指示信息指示至少一个非授权传输区域的传输资源位置、至少一个查询区域的传输资源位置、以及所述至少一个非授权传输区域和所述至少一个查询区域之间的映射关系。在一个实施例中，所示第一消息可以为系统信息块(system information block，SIB)，即所述第一设备可以通过系统消息向所述至少一个第二设备下发所述至少一个非授权传输区域的传输资源位置和所述至少一个查询区域的传输资源位置、以及相应的映射关系。
S440，至少一个第二设备接收所述第一设备发送的第一消息，并获取第一消息中的第二指示信息，根据第二指示信息获取至少一个非授权传输区域的传输资源位置、至少一个查询区域的传输资源位置、以及所述至少一个非授权传输区域和所述至少一个查询区域之间的映射关系。
S450，第一设备在所述至少一个查询区域(所述至少一个查询区域包括前述的第一查询区域)中向至少一个第二设备下发第二消息，所述第二消息包括第一指示信息，所述第一指示信息用于指示与所述至少一个查询区域相映射的至少一个非授权传输区域中，预分配的传输资源。应理解，前述为了描述方便，第一指示信息指示的是第一查询区域对应的非授权传输区域中的传输资源的分配情况，第一查询区域可以是一个或多个查询区域中任意一个查询区域，所以在后续的举例中，第一指示信息可以指示任何一个查询区域对应的非授权传输区域中的传输资源的分配情况
例如，图5中，第一设备在查询区域2中向至少一个第二设备(如UE1～UE5，其中UE1和UE3为计划重传的UE，而UE2、UE4和UE5为计划初传的UE)下发第二消息，第二消息包括第一指示信息，所述第一指示信息指示与所述查询区域2相映射的非授权传输区域2中，传输资源(如资源块1、资源块3、和资源块9)预分配使用，预分配使用的传输资源将会分配给计划进行上行非授权重传的一个或多个第二设备(如UE1和UE3)。具体的，假设UE1和UE3在非授权传输区域1中进行的上行非授权数据传输失败，但第一设备能够识别出这些失败的数据传输是由UE1和UE3发送，则第一设备向UE1和UE3回复否定应答(negative acknowledge，NACK)，以指示第一设备未能成功接收UE1和UE3发送的数据传输。另外，第一设备可以在发送所述NACK之后(之后可以指时间域上的之后)的查询区域2中指示出UE1和UE3在非授权传输区域2中进行重传所使用的传输资源，如非授权传输区域2中UE1和UE3使用资源块1、资源块3、和资源块9传输重传数据。
可选地，第一设备可以直接指示出UE1和UE3进行重传将使用的传输资源，如UE1 将使用资源块1、UE3将使用资源块3和资源块9；也可以间接指示出需要重传的UE，如UE1和UE3，以及这些重传UE可以使用的传输资源池，如资源块1、资源块3、和资源块9，UE1和UE3则在资源块1、资源块3、和资源块9中随机选择传输资源进行重传。直接指示的好处是避免了UE1和UE3重传时发生碰撞；间接指示的好处是第一设备无需直接指示出UE1和UE3将使用的资源块，间接指示比直接指示的资源开销小，可以提高资源的利用率。
S460，计划进行上行非授权传输的第二设备(如UE1～UE5)在至少一个查询区域中接收第一设备下发的第二消息，该第二消息携带第一指示信息，计划进行上行非授权传输的第二设备根据第二消息获得与查询区域对应的非授权传输区域中，预分配使用传输资源。如UE1～UE5可以通过查询区域2中接收到的第二消息中的第一指示获知与查询区域2相映射的非授权传输区域2中资源块1、资源块3、和资源块9被预分配使用。需要说明的是，如图8所示，对于计划重传的第二设备(如UE1)，如果前次传输所使用的传输资源(如非授权传输区域1中的资源块1)与重传所使用的传输资源存在映射关系(如映射至非授权传输区域2中的资源块1)，则计划重传的第二设备可以无需通过查询区域便获得与该查询区域相映射的非授权传输区域中预分配使用的传输资源位置，以减少UE1接收第二消息带来的开销。
S470，第二设备计划进行上行非授权数据传输时，如果第二设备计划初传，如UE2、UE4、和UE5，则以更高的概率选择未分配使用的传输资源(也即选择未分配的传输资源的概率大于预分配的传输资源的概率)，以降低与计划重传的第二设备(如UE1、UE3)发生碰撞的概率。这里，初传的第二设备可以完全避免选择查询区域中指示的预分配的传输资源，以完全避免与重传的第二设备发生碰撞；初传的第二设备也可以按第三概率选择未分配使用的传输资源，按第四概率选择预分配的传输资源，通常来说第三概率可以大于第四概率，以减少与重传的第二设备发生碰撞的概率，提升了上行非授权传输的可靠性。
如果第二设备计划重传，如UE1和UE3，则第二设备以更高的概率选择预分配的传输资源(也即选择预分配的传输资源的概率大于未分配的传输资源的概率)，以降低计划重传的第二设备与计划初传的第二设备(如UE2、UE4、和UE5)发生碰撞的概率。这里，重传的第二设备可以仅使用查询区域中指示的预分配的传输资源，以完全避免与初传的第二设备发生碰撞，如果第二消息中携带的第一指示信息已明确指示出每个重传的第二设备将使用的传输资源，则计划重传的第二设备之间也不是发生碰撞；重传的第二设备也可以按照第二概率选择未分配使用的传输资源，按第一概率选择预分配的传输资源，通常来说第二概率可以小于第一概率，以减少重传的第二设备与初传的第二设备发生碰撞的概率，提升了上行非授权传输的可靠性。
可选地，对于计划重传但没有收到NACK的第二设备，则可以当作初传的第二设备以更高的概率选择未分配使用的传输资源，具体细节可以参考计划初传的第二设备，这里不再一一赘述。
因此，本申请实施例中第一设备为需要重传的第二设备在后续非授权传输区域中预分配传输资源，减少初传的第二设备与重传的第二设备之间发生碰撞的概率，同时第一设备通过为重传的第二设备分配不同的传输资源，能够免重传的第二设备之间的碰撞，提升了上行非授权传输的可靠性。
又一个例子，在该例子中ACK区域可以作为查询区域，为了减少第一设备确定并配置至少一个查询区域所带来的开销，可以将至少一个查询区域与ACK反馈区域融合。这里ACK反馈区域是指第一设备(如基站)收到至少一个第二设备发送的数据后，回复的确认消息所在的区域物理混合自动重传指示信道(physical HARQ indicator channel，PHICH)，图9示出了本申请实施例提供的方法500，包括：
S510，同S410。
S520，第一设备确定至少一个ACK查询区域(简称ACK区域)，以及该ACK区域与至少一个非授权传输区域的映射关系。所述ACK区域不但指示与其相映射的前一非授权传输区域(前述的第三非授权传输区域)中的非授权传输是否成功，还用于指示与其相映射的下一非授权传输区域(前述的第一查询区域对应的非授权传输区域)中预分配的传输资源。如图10所示，ACK区域1-ACK区域3分别对应非授权区域1-非授权区域3的ACK反馈区域，用于网络设备向终端设备确认是否收到上行数据；同时，ACK区域0-ACK区域2分别映射非授权传输区域1-非授权传输区域3，用于指示相映射的非授权传输区域中预分配的传输资源。
需要说明的是，这里的映射不但指ACK区域和非授权传输区域之间的映射，还指ACK区域中传输资源位置和非授权传输区域中传输资源位置的映射。如图11所示，ACK区域0中具体的传输资源位置和非授权传输区域1中的具体的传输资源位置也是相互映射的。应说明的是，由于不同的未授权传输区域之间所占用的时频域资源可能不同，因此对于占据时频域资源较多的非授权传输区域(如非授权传输区域2)，其传输资源可以分为映射部分和非映射部分，对于非映射部分的传输资源，可以无需遵循前述映射关系。
S530，同S430。
S540，同S440。
S550，第一设备在所述至少一个ACK区域中下发第二消息，所述第二消息携带第一指示信息，该第一指示信息用于指示与所述至少一个ACK区域相映射的至少一个非授权传输区域中，上行数据传输的ACK反馈，以及与所述至少一个ACK区域相映射的至少另一个非授权传输区域中，预分配的传输资源(例如图11中非授权传输区域1与非授权传输区域2中的预分配的传输资源)。
在一个实施例中，如图11所示，如果ACK区域1的ACK反馈为ACK，则说明非授权传输区域1中映射的上行数据传输成功，同时说明在下一映射的非授权传输区域(如非授权传输区域2)中的传输资源尚未被预分配；如果ACK区域1的ACK反馈为NACK，则说明非授权传输区域1中映射的上行数据传输失败，但第一设备可以识别出进行上行数据传输的第二设备，因此在下一映射的非授权传输区域2中的传输资源已被预分配；如果ACK区域1的ACK反馈为空，即第一设备没有发送ACK消息，则说明非授权传输区域1中映射的上行数据传输失败，同时第一设备无法识别出进行上行数据传输的第二设备，因此在下一映射的非授权传输区域2中的传输资源尚未被预分配。
在另一个实施例中，所述无线通信系统支持上行非授权传输多址接入，即同一时频域资源上可以同时接入多个第二设备发送的数据。以多用户共享接入(multi-user shared access，MUSA)为例，在所述同一时频域资源上同时进行有效数据传输的多个第二设备需要使用不同的扩频序列才能避免相互之间的干扰。换句话说，多址接入在传统的时频域资源外通过增加新的维度，使得同一时频域资源上的多个第二设备可以同时传输数据。 由于多址接入技术较多，这里不再一一赘述。
这里，如图12所示，所述ACK区域(如ACK区域0)不但可以反馈之前的上行传输是否成功，还可以指示与该ACK区域相映射的非授权传输区域中已预分配使用对应传输资源的第二设备数量。比如“1”指示有一个第二设备预分配使用该传输资源(如计划重传的第二设备)，“2”指示有两个第二设备预分配使用该传输资源，以此类推。空白区域或“0”则指示第一设备没有在其映射的传输资源上成功收到有用的数据信号。
需要说明的是，ACK区域接收到的第一指示信息可以指示的与该ACK区域相映射的非授权传输区域中已预分配使用对应传输资源的第二设备数量，则第二设备计划进行上行非授权数据传输时，如果为初传的第二设备，则所述第二设备以更高概率(例如前述的第三概率)选择空白区域或“0”所映射的传输资源进行上行非授权数据传输；如果为重传的第二设备，则所述第二设备根据ACK区域0中的反馈以更高概率(例如前述的第一概率)选择数值较高(即，已预分配使用传输资源的第二设备数量较多)的传输资源在下一非授权传输区域中进行重传，如ACK区域中指示为“2”或“3”，即有2个或3个第二设备已计划在下一非授权传输区域中对应的传输资源进行重传。
S560，同S460。
S570，同S470。
又一个例子，在该例子中，将第二设备发送的上行数据可以是控制部分和/或数据部分，控制部分较短，控制部分携带在第五消息中，数据部分携带在第六消息中，控制部分至少包括第二设备的标识或第二设备的部分标识(如UE的ID或部分ID，或其他可以识别UE的信息)，还可以包括调制编码方案(modulation and coding scheme，MCS)、数据大小等信息中的一种或多种；数据部分则用于承载有用数据信息。第一设备(如基站)先接收第二设备发送的第五消息，然后可以根据第五消息中指示的信息对第六消息进行解调，以降低对数据部分解调的复杂度。
本申请实施例中，第二设备首先发送较短的第五消息(即上行非授权消息的控制部分)，第一设备在查询区域(或ACK区域)对是否成功收到第五消息进行确认，如果第一设备成功收到第五消息，则第一设备为所述第二设备在所述查询区域映射的非授权传输区域中预分配第六消息(数据部分)所使用的传输资源。
计划发送第五消息的第二设备根据查询区域的指示以更高概率(如前述的第五概率)选择未被预分配使用的传输资源发送第五消息；而计划发送第六消息的第二设备则根据查询区域的指示以更高概率(如前述的第七概率)在映射的已预分配使用的传输资源中发送第六消息。具体地，图13示出了本申请实施例提供的方法600，包括：
S610，同S510。
S620，同S520。
S630，在方法500中，ACK区域中第一指示信息可以指示与该ACK区域相映射的非授权传输区域中已预分配使用对应传输资源的第二设备数量，以适用多址接入的场景。而在同一时频域传输资源上采用多址接入的多个第二设备，如果使用的稀疏码多址接入(sparse code multiple access，SCMA)中的码本/码字、或MUSA中的扩频序列、或图样分割多址接入(pattern division multiple access，PDMA)中的图样、多其他多址接入技术的映射规则相同，则使用相同映射规则的多个第二设备之间仍可能发生碰撞。
可选地，在一个实施例中，所述ACK区域中的第一指示信息可以指示所映射传输资 源上可用/已用的多址接入映射规则，如码字、扩频序列、图样等，并且可以进一步分为控制ACK区域和数据ACK区域，以分别对控制部分和数据部分进行ACK反馈。以多址接入技术MUSA的扩频序列长度为2bits为例，如图14所示的控制ACK区域对应某一时频域资源上4种可能的扩频序列(B_m～B_m+3位)的ACK反馈，其中“1”可以指示对应的扩频序列已被预分配使用，并且已有第二设备计划在该ACK区域映射的下一非授权传输区域的传输资源中进行上行非授权传输，如计划进行数据部分的传输(如第六消息)；“0”则可以指示对应的扩频序列尚未被预分配使用，如初传失败；空白区域则说明第一设备没有检测到信号，也可以指示对应的扩频序列在下一非授权传输区域中映射的传输资源尚未被预分配使用。
S640，同S540。
S650，同S550。
S660，同S560。
S670，第二设备计划进行上行非授权传输时，如果第二设备计划发送第五消息，即发送控制部分，则根据查询区域以更高概率(例如前述的第五概率)选择未被预分配使用的传输资源，也可以仅从未被预分配使用的传输资源中选择，以完全避免与其他第二设备发送的第六消息发生碰撞；如果第二设备计划发送第六消息，即发送数据部分，则根据查询区域以更高概率(例如前述的第七概率)选择已被预分配使用的传输资源，也可以仅从已被预分配使用的传输资源中选择，以完全避免与其他第二设备发送的第五消息发生碰撞。
因此，本申请实施例中，第二设备通过较短第五消息可以预分配后续较长的第六消息所使用的传输资源，可以保证后续进行的第六消息传输时没有其他无线通信设备竞争使用相同的传输资源；另外，对于计划进行上行非授权传输的一个或多个第二设备，可以通过较短的第五消息试探竞争传输资源，还避免了一次传输较多的数据(如完整的非授权数据)失败后而导致重传开销过大。
又一个例子，上行非授权传输至少可以用于URLLC和mMTC场景，其中URLLC业务重点关注低时延，即首传要快，重传尽量保障成功率，同时避免传输总时延超过传统授权传输(Grant based transmission)；而mMTC业务以小包为主，待传输的数据数量众多，对时延不太敏感，即可以容忍一定的时延，同时可靠性不能太低，以避免产生大量重传造成碰撞过多。因此，第一设备需要对非授权传输区域进行配置。
具体地，第一设备将非授权传输区域分为至少两类并下发相关信息：时延敏感型非授权传输区域和高可靠型非授权传输区域。其中时延敏感型非授权传输区域与传统非授权传输区域相同，高可靠型非授权传输区域则与方法200-方法600中的至少一个查询区域和/或的ACK区域有映射关系。
对于时延不敏感的一个或多个第二设备，如前述进行mMTC业务的一个或多个第二设备，则优先选择高可靠型非授权传输区域中的传输资源进行上行非授权传输，如图15所示的高可靠非授权传输区域2和高可靠非授权传输区域4，具体选择所述传输资源的方法请参见方法200-方法600，这里不再赘述。
对于时延敏感的一个或多个第二设备，如前述进行URLLC业务的一个或多个第二设备，则优先选择时延敏感非授权传输区域中的传输资源进行首次上行非授权传输(即初传)，如图15所示的时延敏感非授权传输区域1和3；如果初传失败，则切换至高可 靠非授权传输区域(如高可靠非授权传输区域2)中进行重传，同时所述一个或多个第二设备在所述高可靠非授权传输区域2中进行重传所使用的传输资源在相映射的查询区域2中进行指示，以保证对时延敏感的一个或多个第二设备的重传可靠性。需要说明的是，在所述查询区域2中指示所述一个或多个第二设备进行重传所使用的传输资源的方法请参见方法200-方法600，这里不再赘述。
