Description

传输定时信息发送方法、接收方法及装置
本申请要求于2016年11月3日提交中国专利局、申请号为201610956629.2、申请名称为“传输定时信息发送方法、接收方法及装置”的中国专利申请以及于2017年2月10日提交中国专利局、申请号为201710074473.X、申请名称为“传输定时信息发送方法、接收方法及装置”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本发明涉及通信技术领域，尤其涉及一种传输定时信息发送方法、接收方法及装置。
背景技术
在现有系统中(如LTE)，基站和用户设备采用FDD(Frequency Division Duplex，频分双工)或TDD(Time Division Duplex，时分双工)方式进行数据信息交互。基站与终端设备通信时使用的传输定时关系，通过预定义的方式被基站和终端设备所获取，其中，传输定时可以是从基站发送下行数据传输到终端设备发送上行确认反馈信息的时间间隔，例如混合自动重传请求(Hybrid Automatic Repeat request,HARQ)定时，或者可以是从基站发送上行调度指示信息到终端设备设备发送上行数据传输的时间间隔。例如，在采用FDD方式传输时，基站在第n子帧发送下行数据，终端设备在第n+4个子帧反馈数据包的ACK/NACK(肯定应答/否定应答)信息，则传输定时信息/HARQ定时信息为4个子帧。
类似的，在采用TDD方式传输时，当基站发送的数据包的初传子帧为n，则一般规定终端设备在子帧n+4上反馈ACK/NACK信息，由于无线帧中上行子帧和下行子帧的配置比例(简称：子帧上下行配比)不同，所以难以实现随时在n+4子帧上反馈信息，因此，标准中预定义了在给定上下行子帧配置比例下的HARQ定时信息。
在下一代无线通信系统中，随着系统中支持的业务类型多样化，系统应用场景多样化，而且，在动态TDD情况下，无线帧中上下行子帧类型动态变化等，会导致传输定时关系的数量增多。沿用预定义的方式，会导致系统灵活性下降，无法实现下一代系统的设计需求；而如果采用DCI(Downlink Control Information，下行控制信息)对传输定时进行指示，则需要在该DCI中预先定义较长的信息比特，包括所有可能的定时关系，造成控制信令的开销增大。

具体实施方式
为方便后续描述并清楚地对本申请进行说明，以下首先对本申请可能用到的概念做简要说明：
在本申请各个实施例中涉及的通信系统可以是LTE系统或是5G系统。该通信系统包括至少一个终端设备和至少一个网络设备。
所述终端设备可以是指向用户提供信息和或数据连通性的设备，具有无线连接功能的手持式设备，或连接到无线调制解调器的其他处理设备。终端设备可以经无线接入网(radio access network，RAN)与一个或多个核心网进行通信，终端设备可以是移动终端，如移动电话(或称为“蜂窝”电话)和具有移动终端的计算机，例如，可以是便携式、袖珍式、手持式、计算机内置的或车载的移动装置，它们与无线接入网交换语言和或数据。例如，个人通信业务(personal communication service，PCS)电话、无绳电话、会话发起协议(session initiation protocol，SIP)话机、无线本地环路(wireless local loop，WLL)站、个人数字助理(personal digital assistant，PDA)等设备。终端设备也可以称为系统、订户单元(subscriber unit，SU)、订户站(subscriber station，SS)，移动站(mobile station，MS)、远程站(remote station，RS)、接入点(access point，AP)、远端设备(remote terminal，RT)、接入终端(access terminal，AT)、用户终端(user terminal，UT)、用户代理(user agent，UA)、用户设备、或用户装备(user equipment，UE)。所述网络设备可以是基站、增强型基站、或具有调度功能的中继、或具有基站功能的设备等。其中，基站可以是LTE系统中的演进型基站(evolved Node B，eNB)，也可以其他系统中的基站，本申请实施例并不限定，如下以基站为例进行说明。
在本申请各个实施例中，传输定时用于指示终端设备在接收到基站发送的下行数据后，向基站反馈上行确认信息的时间间隔，或者，用于指示终端设备向基站发送上行调度信息到所述终端设备发送上行数据的时间间隔。例如，HARQ定时。
在本申请各个实施例中，所述反馈上行确认信息，或者反馈信息可包括肯定应答(acknowledgement，ACK)信息及否定应答(negative acknowledgment，NACK)信息。基站根据接收到的ACK/NACK信息，确定是否进行数据包的重传。如果基站接收到的是ACK信息，则发现新的数据包的传输，如果基站接收到来自终端设备反馈的是NACK信息，则发起数据包重传操作。
本申请实施例提供了一种传输定时信息发送方法，用于提高传输定时配置的灵活性，并且节约DCI指示信息的开销，如图1所示，方法包括如下步骤：
步骤101：基站配置高层信令，所述高层信令中包括用于指示传输定时取值的至少一个传输定时集合，所述至少一个传输定时集合中的每个传输定时集合中包括至少一个传输定时取值，其中，所述至少一个传输定时集合与如下因素中的至少一种有关：子载波宽度、TDD方式、终端设备能力、系统上行下行配比等信息。
所述系统上行下行配比为系统中每个时隙的时隙类型的组合关系，例如：每连续十个时隙为一组，组内每个时隙的时隙类型为，全上行时隙，全下行时隙，主上行时隙，和主下行时隙中的一个时隙类型；
所述TDD方式，包括半静态TDD系统，动态TDD系统；在半静态TDD系统中，每个时隙的时隙类型通过高层信令指示或预定义的方式确定；在动态TDD系统中，每个时隙的时隙类型通过物理层信令进行通知；所述时隙的类型，包括全上行时隙，全下行时隙，主上行时隙，和主下行时隙。
基站配置高层信令具体包括：基站根据终端设备能力、子载波宽度、TDD方式和系统上行下行配比中的一个或者多个因素划分不同的传输定时集合，每个传输定时集合中包括多个传输定时取值。例如，高层信令中包括第一传输定时集合和/或第二传输定时集合，第一传输定时集合表示为，集合中的每个值即为一个传输定时取值，第二传输定时集合表示为。
其中，第一传输定时集合和第二传输定时集合中的传输定时取值可以是不同业务下的不同取值，也可以是不同终端设备能力下的不同取值，还可以是不同TDD方式下的不同取值，或者是不同子帧上下行配比的不同取值。例如，为数据处理能力强的终端设备配置第一传输定时集合，为数据处理能力弱的终端设备配置第二传输定时集合；或者根据上下行配比为第一配比的系统配置第一传输定时集合，根据上下行配比为第二配比的系统配置第二传输定时集合，其中第一配比与第二配比不同；或者系统为半静态TDD系统配置第一传输定时集合，为动态TDD系统配置第二传输定时集合，另外，还可以根据发送的DCI所在的时频资源确定和配置不同的传输定时集合。其中，UL(Uplink，上行链路),DL(Downlink，下行链路)。
传输定时取值可以是指基站向终端设备发送下行数据后，接收所述终端设备发送的上行确认信息的时间间隔信息，还可以指终端设备向基站发送上行调度信息到所述终端设备发送上行数据的时间间隔信息，其中，所述时间间隔信息包括时隙的数量。例如：基站在第n个子帧或时隙发送下行数据，终端设备在n+k子帧或时隙上发送上行确认信息；其中，k的取值为高层信令配置的传输定时取值集合中的一个值。
可选的，当终端设备处于特定情况时，所述至少一个传输定时集合失效，所述传输定时集合中的取值不再适用。该特定情况可能为，例如小区切换，或重新建立RRC连接等情况。
可选的，所述传输定时集合中的定时取值还包括至少一个默认取值。当所述至少一个传输定时集合失效时，所述终端设备根据所述默认取值确定传输定时的取值。例如：选取传输定时的取值等于所述默认取值。
可选的，所述默认取值可以是系统预定义的，即基站和终端设备都预先可获知的取值，也可以是可配置的取值，例如，终端设备可根据接收到的系统信息或与随机接入有关的信息确定的取值，其中，随机接入有关的信息可终端设备进行初始接入时，基站发送的第二消息或第四消息。
通过设置默认取值，可以解决以下技术问题：即在终端设备使用的所述至少一个定时集合失效后，基站若采用新的定时取值，而终端设备仍采用失效的定时取值，可能造成数据无法有效的传输。
步骤102：基站将所述高层信令发送给终端设备。
步骤103：基站确定下行控制信息DCI，所述DCI用于指示终端设备在所述至少一个传输定时集合内确定一个传输定时取值，所述确定的传输定时取值为指示所述终端设备指示在发送反馈信息时使用的时隙。
具体地，所述DCI中包括指示第一传输定时集合和第二传输定时集合中传输定时取值的信息字段。例如，DCI中包括指示传输定时取值的信息字段，该信息字段用于指示一个传输定时集合中的具体传输定时取值。进一步地，高层信令配置的一个集合 为，此时DCI中包括一个2bit的指示字段，用于指示终端设备反馈当前子帧调度的下行数据的传输的确认信息的时间间隔，如果DCI取值为“00”，则对应该集合中的传输定时取值为k1。当该终端设备接收到的DCI后，指示传输定时的取值为“00”，则终端设备在n+k1时隙或子帧上向基站反馈ACK/NACK等确认信息。
一种传输定时信息指示方式是，根据所述DCI的格式与第一信息字段联合指示传输定时取值，具体指示过程包括：DCI的DCI格式中包括第一信息字段，基站根据所述第一信息字段指示一个传输定时集合中的一个传输定时取值；其中，当有两个或两个以上传输定时集合时，所述DCI用于指示终端设备在这些传输定时集合中确定一个传输定时取值，
基站根据所述DCI的DCI格式确定所述至少一个传输定时集合中的一个传输定时集合，所述DCI格式中包括第一信息字段，所述第一信息字段用于指示所述具有绑定关系的集合内的一个传输定时取值；或者，根据所述DCI占用控制信道时频资源上发送，根据所述控制信道时频资源确定所述多个传输定时集合中至少一个传输定时集合。
另一种传输定时信息指示方式是，第一信息字段和第二信息字段联合指示传输定时取值。具体地，可以根据所述DCI的格式，所述DCI的DCI格式中包括第一信息字段，根据所述第一信息字段指示一个传输定时集合中的一个传输定时取值；其中，当包括两个或者两个以上传输定时集合时，所述DCI用于指示终端设备在这些传输定时集合中确定一个传输定时取值，此外，所述DCI的DCI格式中还可以包括第二信息字段，所述第二信息字段用于确定多个传输定时集合中的一个传输定时集合。
可选的，当如步骤101所述，当所述传输定时集合中的定时取值还包括至少一个默认取值时，在步骤103中，可选的，基站确定下行控制信息DCI，所述DCI用于指示终端设备在所述至少一个传输定时集合内确定一个传输定时取值，包括：所述DCI中的指示字段指示终端设备使用该默认取值。例如，如前所述示例，DCI中包括一个2bit的指示字段，用于指示终端设备反馈当前子帧调度的下行数据的传输的确认信息的时间间隔，如果DCI取值为“00”，则对应该集合中的传输定时取值根据所述默认取值确定传输定时的取值；当指示信息为“01,10,11”时，则用于指示终端设备根据所述定时集合中的其余取值确定传输定时的取值。
步骤104：基站将所述DCI发送给所述终端设备。
在基站发送DCI时，DCI中的指示信息所指示的时隙一定包括可用于传输上行ACK/NACK的上行传输资源；而对于传输上行ACK/NACK的具体时频资源位置，可以通过与调度的下行传输数据具有绑定关系，例如，上行ACK/NACK的频域资源信息与调度的下行传输资源的第一PRB(Physical Resource Block，资源块)所在的频域位置具有绑定关系。
其中，基站可以通过一级控制信道将所述DCI发送给所述终端设备，或者，通过一级控制信道和二级控制信道共同将所述DCI发送给终端设备，其中该DCI位于所述二级控制信道中。
如图2所述，表示一种两级控制信道结构示意图，其中，一级控制信道位于整个时隙或子帧的控制区，二级控制信道位于子帧的数据区。如果该DCI通过一级控制信道和二级控制信道联合发送，则在一级控制信道中包括资源调度指示信息，该资源调 度指示信息用于指示所述DCI在二级控制信道中的时频资源位置；所述二级控制信道用于承载指示传输定时取值的信息。其中，GP(Guard Period，保护间隔)UL。
本实施例提供了一种高层信令和下行控制信息DCI联合指示传输定时的方法，预先在高层信令中配置至少一个传输定时取值集合，再通过DCI指示选定集合中的一个具体传输定时取值；由于每个传输定时集合中的取值元素是根据系统当前的业务情况，子帧配比等因素确定，所以当终端设备接收到包含至少一个传输定时集合的高层信令时，基站只需通过DCI携带指示终端设备的传输定时取值即可，避免携带较大长度的信息比特，节省了控制信息开销，
进一步地，基站在配置DCI与传输定时集合之间对应关系的过程中，包括如下情况：
一种情况是，基站通过DCI的格式与至少一个传输定时集合建立绑定关系，以使终端设备能够根据该DCI的格式确定传输定时集合，所述DCI格式中包括第一信息字段，所述第一信息字段用于指示所述具有绑定关系的集合内的一个传输定时取值。例如，所述第一信息字段包括第一集合中的一个具体取值。
另一种情况是，建立一个DCI格式与两个或者两个以上传输定时集合之间的绑定关系，即该DCI格式中包括第一信息字段和第二信息字段，第一信息字段与一个传输定时集合具有绑定关系，所述第一信息字段用于指示在多个集合中具有绑定关系的传输定时集合；第二信息字段用于指示所述具有绑定关系的集合中的一个传输定时取值。
又一种情况是，基站还可以根据控制信道时频资源建立与至少一个传输定时集合之间的绑定关系，具体地包括，控制信道时频资源包括多个区域，每个区域用于传输DCI，且每个区域对应一个传输定时集合，终端设备在接收到DCI之后根据该DCI所在控制信道时频资源区域信息确定其对应的传输定时集合。
又一种情况是，基站根据DCI的DCI格式包括的信息比特的长度建立与不同传输定时集合之间的绑定关系。例如，将信息比特长度小于阈值的DCI与第一传输定时集合建立绑定关系，将比特长度大于或等于该阈值的DCI与第二传输定时集合建立绑定关系。
需要说明的是，以上仅列举了几种建立绑定关系的情况，包括但不限于上述情况，基站还可以根据子载波宽度、上下行子帧配比等其它因素建立传输定时集合与DCI之间的绑定关系，例如，基站根据子载波宽度子载波宽度宽度确定DCI，所述DCI用于指示在该子载波宽度下的传输定时取值，所述DCI与所述子载波宽度下的传输定时集合具有绑定关系。
为了提高传输定时取值指示的灵活性，所述传输定时集合中的传输定时取值会随着DCI的变化发送变化。
进一步地，高层信令中的至少一个传输定时集合中包括第一子载波集合，且该第一子载波集合中的传输定时取值由子载波宽度确定。当子载波宽度变化时，对应的第一子载波集合中的传输定时取值也发生变化。
例如，在第一时刻，基站根据当前子载波宽度确定第一DCI，该第一DCI用于指示第一子载波集合中的一个传输定时取值；在第一时刻之后的某一时刻，例如第二时刻，基站根据第二时刻的子载波宽度生成第二DCI，该第二DCI中包括用于指示传输 定时取值或，则在第一时刻的第一子载波集合在第二时刻变成，基站通过配置高层信令对传输定时集合进行调整以及DCI的指示，实现传输定时的灵活指示。
可替代地，如果包括两个或者两个以上传输定时集合与子载波宽度有关，则配置和建立绑定关系的方式可以是：
根据不同时刻不同子载波宽度分别配置不同传输定时集合。以两个传输定时集合为例，第一子载波集合和第二子载波集合，其中，第一子载波集合中的传输定时取值根据第一子载波宽度确定，所述第二载波集合中的传输定时取值根据第二子载波宽度确定，系统配置为第一子载波宽度时，基站确定DCI，所述DCI对应第一子载波集合；系统配置为第二子载波宽度时，基站确定DCI，所述DCI对应第二子载波集合。所述第一子载波宽度和第二子载波宽度可以在同一系统内通过频分复用或时分复用的方式进行配置；本实施例中，例举的基站根据子载波宽度确定DCI中的指示传输定时取值进一步地提高指示信息的灵活性。
在本申请的另一个实施例中，在接收端侧还提供了一种传输定时信息接收方法，如图3所示，该方法包括如下步骤：
步骤301：终端设备接收来自基站的高层信令和下行控制信息DCI。
其中，所述高层信令中包括用于指示传输定时取值的至少一个传输定时集合，所述至少一个传输定时集合中的每个传输定时集合中包括至少一个传输定时取值，所述DCI用于指示所述终端设备在所述至少一个传输定时集合内确定一个传输定时取值；其中，所述至少一个传输定时集合与如下因素中的至少一种有关：子载波宽度、TDD方式、终端设备能力等。
进一步地，终端设备可以先接收基站发送的高层信令，再接收DCI；或者，终端设备同时接收基站发送的高层信令和DCI；或者，如果在终端设备中已经预先配置或者获取了高层信令，则可以直接接收基站发送的DCI，不需要在接收DCI之前获取高层信令了。
其中，基站在划分高层信令和配置DCI的过程与前述实施例中描述的方法相同，此处不再赘述。
步骤302：终端设备根据所述DCI在所述至少一个传输定时集合内确定一个传输定时取值，并在所述确定的传输定时取值所对应的时隙上发送数据信息和或反馈信息给所述基站。
一种可能的实现方式是，终端设备获取高层信令和DCI之后，先根据该DCI的格式确定所述多个传输定时集合中一个传输定时集合；再根据所述DCI中包括的信息字段内承载的指示信息在所述确定的传输定时集合中确定一个传输定时取值。其中，所述信息字段包括指示比特值、资源分配和调制方法等信息。
如果终端设备获取两个或者两个以上DCI，则该终端设备可以根据每个DCI与传输定时间之间的绑定关系，确定每一个DCI对应的传输定时集合，再根据该DCI中的信息字段，确定在该集合中的一个传输定时取值。例如，终端设备在同一时隙内接收到两个DCI，记为第一DCI和第二DCI，这两个DCI的格式不同，并且第一DCI与第二DCI中包括的信息字段也不相同。第一DCI中的信息字段包括：资源分配，调制方法，传输定时信息等信息；第二DCI中的信息字段包括：调制方法，传输定时信息等。
在确定DCI与传输定时集合的对应关系时，一种可能的情况是，第一DCI中包括的信息比特长度与第二DCI中包括的信息比特长度不同。基站在配置传输定时集合时，可以根据信息比特的长度建立与DCI之间的绑定关系。例如，将信息比特长度小于设定阈值的DCI与第一集合建立绑定关系，将信息比特长度大于该阈值的DCI绑定第二集合。再通过第一DCI和第二DCI中携带的信息分别确定第一传输定时集合和第二传输定时集合中传输定时取值。
另一种可能的情况是，第一DCI或第二DCI中包括一个信息字段，用于指示其所在的DCI对应的第一传输定时集合或第二传输定时集合。具体地，所述信息字段包括1比特的指示信息，当比特值取“0”时，终端设备确定第一传输定时集合；当比特值取“1”时，确定第二传输定时集合。
可替代地，如果终端设备通过一级控制信道和二级控制信道获取所述DCI，则根据该DCI在所述至少一个传输定时集合中确定一个传输定时取值包括：
所述终端设备从所述一级控制信道中获取资源调度指示信息；
根据所述资源调度指示信息确定所述二级控制信道的时频资源位置；
根据所述二级控制信道的时频资源位置上承载的DCI确定在所述至少一个传输定时集合中确定一个传输定时取值。
本实施例提供了的方法，先通过高层信令配置多个定时取值集合，再通过物理层控制指示信息DCI指示定时的具体数值；实现对传输定时取值的灵活配置，同时配合物理层指示信息可以动态指示多个定时关系。
另外，每个DCI绑定至少一种传输取值集合，可以根据DCI格式，DCI的信息比特长度，子载波宽度等进行绑定；进而建立一种隐性指示DCI与传输定时取值集合的关系，节省了DCI的信令开销。
