Description

数据传输方法、数据传输反馈方法和相关设备 技术领域
本发明涉及通信领域，尤其涉及一种数据传输方法、数据传输反馈方法和相关设备。
背景技术
在LTE(long term evolution，长期演进，简称LTE)通信系统中，上行数据采用GB(grant based，基于授权的)传输机制，基站在PHICH(physical hybrid ARQ indicator channel，物理混合自动重传请求信道)信道中携带反馈信息来指示基站是否正确接收到上行数据，反馈信息包括ACK(acknowledge，确认，简称ACK)反馈信息和NACK(negative acknowledge，非确认，简称NACK)反馈信息，ACK表示基站成功接收并解调上行数据，NACK表示基站未成功接收上行数据。在PHICH中，不同的上行数据的反馈信息通过码分多址的方式进行复用。
在5G通信系统中，业界正在考虑基站通过比特位图的方式发送多个UE的反馈信息的技术。在现有的通过比特位图发送多个UE的反馈信息中，各个UE(user equipment，用户设备)根据各自导频序列的索引和时频资源块的索引确定自己的反馈信息在比特位图中的位置，UE根据反馈信息决定是否需要进行重传。这种方案存在的问题是：各个UE需要知道全局的UE导频序列的数量和时频资源块的数量等相关信息才能计算反馈信息在比特位图中的位置，因此需要基站发送额外的信令通知各个UE全局的导频序列的数量和时频资源块的数量，增加了信令开销和传输时延。

具体实施方式
下面结合本发明实施例中的附图对本发明实施例进行描述。
图1为本发明实施例涉及的一种通信系统架构示意图，所述通信系统包括网络设备和终端设备。图1示出了1个网络设备与1个终端设备进行通信。该通信系统可以是全球移动通信系统(global system for mobile communication，GSM),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，全球微波互联接入(worldwide interoperability for microwave access，WiMAX)系统、长期演进(long term evolution，LTE)系统，5G通信系统(例如新空口(new radio，NR)系统、多种通信技术融合的通信系统(例如LTE技术和NR技术融合的通信系统)，或者后续演进通信系统。图1中所示的网络设备和终端设备的形态和数量仅用于举例，并不构成对本发明实施例的限定。
本申请中的终端设备是一种具有无线通信功能的设备，可以是具有无线通信功能的手持设备、车载设备、可穿戴设备、计算设备或连接到无线调制解调器的其它处理设备等。在不同的网络中终端设备可以叫做不同的名称，例如：终端设备、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、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)、5G网络或未来演进网络中的终端设备等。
本申请中的网络设备是一种部署在无线接入网用以提供无线通信功能的设备，包括但不限于：基站(例如：BTS(base transceiver station，BTS)，节点B(NodeB，NB)，演进型基站B(evolutional node B，eNB或eNodeB)，NR系统中的传输节点或收发点(transmission reception point，TRP或者TP)或者基站(generation nodeB，gNB)，未来通信网络中的基站或中继站、接入点、车载设备、可穿戴设备，无线保真(wireless-fidelity，Wi-Fi)的站点、无线回传节点、小站、微站等等。
目前的反馈信息的发送方法为：网络设备在比特位图中确定目标比特位，确定目标比特位上的值，网络设备向终端设备发送比特位图，终端设备根据导频序列索引确定反馈信息在比特位图中的位置。由此可见，在目前的反馈方法中，网络设备需要通知各个终端设备全局的导频序列配置信息和资源块配置信息，以便终端设备根据全局的导频序列配置信息和资源块配置信息在网络设备发送的比特位图中确定反馈信息的位置。比特位图是可以包含在网络设备发送的下行控制信息(Downlink Control Information，DCI)中。
本发明实施例提供一种数据传输方法，终端设备根据网络设备发送的反馈配置信息得知反馈信息的配置，终端设备需要向网络设备发送上行数据时，能直接根据配置信息从网络设备发送的针对上行数据的反馈消息中获取反馈信息，根据反馈信息确定是否需要重传，这样终端设备同时显示方式从网络设备的反馈消息中指定位置获取反馈信息，无需根据网络设备分配全局资源信息和全局的导频序列的数量获取反馈信息的位置，从而减小数据传输的信令开销和时延。
请参见图2a，图2a是本发明实施例提供的一种数据传输方法，该方法包括但不限于如下步骤：
S201、网络设备向终端设备发送反馈配置信息，终端设备接收网络设备发送的反馈配置信息。
其中，反馈配置信息用于指示针对终端设备的上行数据反馈信息的配置，终端设备根据反馈配置信息从网络设备发送的反馈消息(例如：DCI)中确定终端设备的反馈信息。反馈消息中包括多个不同终端设备的反馈信息，反馈信息指示网络设备对终端设备发送的上行数据的接收状态，反馈信息可以指示的接收状态包括：解调上行数据成功、解调上行数据失败和未接收到上行数据三种状态。
可选的，网络设备向终端设备发送携带反馈配置信息的高层信令，终端设备可在网络设备发送的高层信令中获取反馈配置信息。高层信令为物理层以上的信令，高层信令包括但不限于RRC消息和MAC消息，例如：所述RRC消息包括无线资源控制连接重配置RRC Connection Reconfiguration消息、无线资源控制连接重建立RRC Connection Reestablishment消息、无线资源控制连接建立RRC Connection Setup消息和RRC Connection Resume消息中的任意一种。
可选的，网络设备向终端设备发送携带反馈配置信息的DCI，终端设备从DCI中获取反馈配置信息。
可选的，反馈配置信息中包括多个参数，网络设备向终端设备发送携带第一反馈配置信息的高层信令，以及向终端设备发送携带第二反馈配置信息的DCI，终端设备从高层信令中获取第一反馈配置信息，以及从DCI中获取第二反馈配置信息，终端设备根据第一反馈配置信息和第二反馈配置信息得到反馈配置信息，第一反馈配置信息和第二反馈配置信息联合指示针对终端设备的上行数据的反馈信息的配置。第一反馈配置信息包括反馈配置信息中的部分参数，第二反馈配置信息包括反馈配置中剩余的另一部分参数。
S202、终端设备向网络设备发送上行数据，网络设备接收终端设备发送的上行数据。
其中，终端设备需要利用传输资源向网络设备发送上行数据，用于发送上行数据的传输资源为网络设备分配的。终端设备既可以采用GB传输机制(或称之为GB传输模式)向网络设备发送上行数据，也可以采用免授权(grant-free，GF)传输机制(或称之为GF传输模式)向网络设备发送上行数据。在与网络设备通信的终端设备的数量为多个的情况下，部分终端设备可以采用GB的传输机制向网络设备发送上行数据，另一部分终端设备可以采用GF的传输机制向网络设备发送上行数据。在GB传输机制中，终端设备在执行上行数据传输之前需要向网络设备发送上行调度请求，网络设备根据终端设备发送的调度请求给终 端设备发送上行授权(UL grant)以通知为终端设备的分配用于上行数据传输的传输资源，终端设备只有在接收到上述上行授权后才采利用上行授权指示的传输资源进行上行数据传输。在GF传输机制中，终端设备在执行上行数据传输之前不需要向网络设备调度请求，而是利用网络设备预先分配的传输资源向网络设备传输上行数据。在GB的传输机制中，终端设备不需要网络设备的上行授权网络就可执行上行数据传输。在本发明实施例中，把通过GB的传输机制传输的上行数据称之为GB数据，把通过GF的传输机制传输的上行数据称之为GF数据。网络设备接收终端设备发送的上行数据，上行数据可能是GB(grant based，基于授权的，简称GB)数据，也可能是GF数据。需要说明的是，终端设备向网络设备发送的上行数据中同时包括GB数据和GF数据时，网络设备分别根据GB数据和GF数据生成不同的反馈信息，GB数据的反馈信息和GF数据的反馈信息位于网络设备生成的反馈消息中的不同位置。
在上行数据为GB数据时，终端设备在发送上行数据之前，需要向网络设备发送上行调度请求，上行调度请求用于向网络设备请求传输上行数据的传输资源，网络设备根据上行数据的数据量、业务类型、优先级等参数判断是否为终端设备分配该传输资源，若为是，网络设备向终端设备发送上行授权，终端设备接收到上行授权后向网络设备发送上行数据。
在上行数据为GF数据时，终端设备无需取得网络设备针对本次上行数据传输的授权而直接采用网络设备为其预先配置的用于发送上行数据的传输资源。网络设备在为终端设备预先配置用于上行数据传输的传输资源时，可以发送上行资源配置信息，上行资源配置信息指示了为终端设备分配的用于传输上行数据的传输资源，终端设备根据上行资源配置信息指示的传输资源发送上行数据。传输资源包括但不限于时频资源、参考信号、扩频序列、扰码和码本中的一种或多种。其中，网络设备可以为终端设备在每个TTI(transmission time interval，TTI)分配1个时频资源块(resource block，RB)，也可以为终端设备在每个TTI分配多个时频资源块，也可以多个TTI为终端设备分配1个时频资源块，即周期性地为终端设备分配时频资源块，本实施例不作限制。网络设备为终端设备分配不同子载波上的时频资源块，以实现跳频的效果，获得频率分集增益，从而提升传输的可靠性。
示例性的，参见图2b所示，图2b中阴影的方格表示可分配给终端设备的时频资源，横坐标表示时域，编号n、n+1、n+2和n+3表示子帧(TTI或者时隙)的序号。纵坐标表示频域，#1、#2、#3和#4表示子带的序号，子带的带宽本实施例不作限制，也根据需要进行设置，例如：子带的带宽为12个子载波的带宽。通信系统的TTI为1个子帧，网络设备在每个子帧内为终端设备分配1个时频资源块：网络设备在子帧n上为终端设备分配#1子带对应的时频资源块，在子帧n+1上为终端设备分配#3子带对应的时频资源块，在子帧n+2上为终端设备分配#2对应的时频资源块，在子帧n+3上为终端设备分配#4对应的时频资源块。网络设备在每个TTI上为终端设备分配不同频段的时频资源块，以实现频率分集增益，提升数据传输的可靠性。
在一种可能的实现方式中，网络设备可以为多个不同的终端设备分配同一个时频资源块，然后通过不同的参考信号(reference signal，RS)来区分不同的终端设备。终端设备的传输资源包括时频资源和参考信号，网络设备需要对时频资源块中不同的终端设备的参考信号进行编号。
一种可能的编号方法为：定义传输资源的编号，通过传输资源的编号确定时频资源块的编号的参考信号的编号。例如：每个TTI对应K个时频资源块，每个时频资源块有L个不同的参考信号，则每个TTI有K*L个传输资源，将传输资源的编号的范围为1至K*L。
另一种可能的编号方法为：分别定义时频资源块的编号和参考信号的编号，根据两个编号确定上行资源的编号。例如：每个TTI对应K个时频资源块，每个时频资源块有L个不同的参考信号，传输资源的编号为(i，j)，1≤i≤K，1≤j≤L，i和j为整数。
可选的，网络设备还可以为终端设备配置物理层参数，物理层参数包括但不限于调制编码方式、冗余版本、参考信号序列参数(例如：ZC(Zadoff-Chu)序列的根)、参考信号序列的循环移位参数中的一种或多种。
S203、网络设备对上行数据进行接收，并生成反馈信息。
网络设备针对终端设备发送的上行数据进行接收时，可能出现三种情况：1、网络设备未检测到终端设备发送的所述上行数据，即，网络设备未接收到上行数据；2、网络设备检测到终端设备发送的上行数据(即，网络设备接收到终端设备发送的上行数据)，但是网络设备未能对接收到的上行数据解调成功；2、网络设备检测到终端设备发送的上行数据(即，网络设备接收到终端设备发送的上行数据)，并且网络设备对接收到的上行数据解调成功。针对上述三种接收情况，网络设备可以生成反馈信息以向终端设备指示网络设备针对其上行数据传输的接收状态，其中，反馈信息可指示解调上行数据成功、解调上行数据失败和未接收到上行数据三种状态。解调上行数据成功表示网络设备接收到终端设备发送的上行数据且成功解调上行数据，解调上行数据失败表示网络设备接收到终端设备发送的上行数据但未成功解调上行数据，未接收到上行数据表示网络设备未检测到终端设备发送的上行数据。
在一种可能的实现方式中，网络设备可采用1个比特位来表示反馈信息。例如：反馈信息的比特位为“1”时表示网络设备解调上行数据成功，反馈信息的比特位为“0”时表示网络设备解调上行数据失败或未接收到上行数据。
在另一种可能的实现方式中，网络设备可采用2个比特位来表示反馈信息。例如：反馈信息的比特位为“00”表示网络设备未接收到上行数据，“01”表示网络设备接收到上行数据但解调上行数据失败，“11”表示网络设备接收到上行数据且解调上行数据成功。
需要说明的是，比特位的值和反馈信息表示的含义的对应关系并不限于上述的举例，可根据需要进行设置，本实施例不作限制。
S204、网络设备向终端设备发送携带反馈信息的反馈消息，终端设备接收网络设备发送的反馈消息。
其中，反馈消息可以为DCI，该DCI中包含对上行数据传输进行反馈的字段。在一实施例中，反馈消息具体可以为公共DCI。公共DCI为针对多个终端设备(或者一组终端设备)的DCI，一条公共DCI包含了针对该多个终端设备(或者一组终端设备)的信息。该公共DCI可用于对同一个终端设备的多个混合自动重传请求(Hybrid Automatic Repeat reQuest，HARQ)进程执行的上行数据传输进行反馈，也可以对多个终端设备的上行数据传输反馈。在本发明实施中，公共DCI中包括针对多个终端设备的上行数据传输的反馈信息，多个终端设备包括S203中发送上行数据的终端设备，多个终端设备的反馈信息位于反馈消 息的不同位置。
在一个实施例中，当一个终端设备使用多个HARQ进程并行发送多个上行数据时，网络设备可以在针对该终端设备的每个HARQ进程发送的上行数据进行反馈，针对该终端设备的上行数据传输的反馈信息包括：针对该终端设备的每个HARQ进程发送的上行数据的反馈信息，该终端设备的不同HARQ进程对应的反馈信息位于反馈消息的不同位置。在另一个实施例中，网络设备还可以在反馈消息中针对同一个终端在不同时隙发送的多个上行数据进行反馈，该终端设备的上行数据传输的反馈信息包括：针对该终端设备在不同时隙发送的多个上行数据的反馈信息，该终端设备在不同时隙发送的上行数据所对应的反馈信息位于反馈消息的不同位置。
在一实施例中，在一个时隙中如果公共DCI对应的多个终端设备(或者一组终端设备)中只有一个终端设备发送了上行数据，网络设备既可以使用用户特定的DCI(UE-specific DCI)也可以使用公共DCI向发送了上行数据的终端反馈其上行数据传输的接收状态。在本实施例中，当使用公开DCI来反馈上行数据传输的接收状态时，反馈消息中未发送数据的终端设备所对应的反馈信息所对应的字段可以设置为默认值(例如，设置为“0“)。有使用UE-specific DCI来反馈上行数据传输的接收状态是现有技术，此处不再赘述。
反馈消息可以在PDCCH(physical downlink control channel，物理下行控制信道，简称PDCCH)或EPDCCH(enhanced physical downlink control channel，增强物理下行控制信道，简称EPDCCH)上发送。
S205、终端设备根据反馈配置信息在反馈消息中确定反馈信息。
其中，终端设备根据S201接收到的反馈配置信息所指示的配置在反馈消息中确定反馈信息表示的接收状态，根据反馈信息表示的接收状态决定是否进行重传。反馈信息指示解调上行数据成功时，终端设备发送新的上行数据。反馈信息表示解调上行数据失败或未接收到上行数据时，终端设备重传上行数据。
可选的，所述反馈配置信息包括所述反馈信息在所述反馈消息中所占用的比特数、反馈时间间隔和所述反馈信息在所述反馈消息中的位置索引中的一种或多种。
其中，比特数表示反馈信息在反馈消息中占用的比特位的数量，反馈时间间隔表示终端设备从发送上行数据到接收到反馈信息之间的时间间隔，位置索引表示终端设备的反馈信息在网络设备发送的反馈消息中的位置。
示例性的，参见图2c所示，网络设备发送的反馈消息包含16个比特位，终端设备接收并解析出网络设备发送的反馈消息为“100010100000000100”，从左往右分别为第0位至第15位。反馈配置信息包括比特数和位置索引，终端设备接收并解析网络设备发送的反馈配置信息为“ANIndex＝4，ANLength＝2”，ANIndex＝4表示反馈信息的比特位位于反馈消息中的第4位，ANLength＝2表示反馈信息的比特位的数量为2，由此可知，终端设备的反馈信息的比特位为“01”，根据S203中的例子，终端设备确定反馈信息表示接收到上行数据但解调上行数据失败，终端设备重新发送上行数据。FreqResource＝2为终端设备的上行资源配置信息，FreqResource＝2表示将每个子帧中的第2个时频资源块分配给上行数据。
示例性的，反馈时间间隔的最小粒度为1个子帧，反馈时间间隔为子帧的长度的整数倍，反馈时间间隔为1个子帧的长度，则终端设备在子帧n上发送上行数据，然后终端设 备设备在子帧n+1上接收网络设备发送的反馈消息。
在一实施例中，反馈配置信息可以用于对终端设备的每个HARQ进程所执行的上行数据传输进行反馈信息的配置。例如，可以为终端设备的每个HARQ进程所执行的上行数据传输配置反馈信息的反馈时间间隔，反馈信息在反馈消息中占用的比特位数，反馈信息在所述反馈消息中的位置索引中的一种或者多种。
在图2a所描述的方法中，终端设备根据网络设备发送的反馈配置信息得知反馈信息的配置，终端设备需要向网络设备发送上行数据时，能直接根据配置信息从网络设备发送的针对上行数据的反馈消息中获取反馈信息，根据反馈信息确定是否需要重传，这样终端设备直接从网络设备的反馈消息中指定位置获取反馈信息，无需根据网络设备分配全局资源信息和全局的导频序列的数量获取反馈信息的位置，从而减小数据传输的信令开销和时延。
