Description

非授权频段的上行传输方法、终端及网络设备
相关申请的交叉引用
本申请主张在2019年2月15日在中国提交的中国专利申请号No.201910118174.0的优先权，其全部内容通过引用包含于此。
技术领域
本公开涉及通信技术领域，尤其涉及一种非授权频段的上行传输方法、终端及网络设备。
背景技术
在第五代(5 th Generation，5G)移动通信系统中，终端或网络设备在非授权频段发送信息之前，需要做信道空闲估计(Clear Channel Assess，CCA)或扩展信道空闲估计(extended Clear Channel Assess，eCCA)来侦听信道，即进行能量检测(Energy Detection，ED)，当能量低于一定门限时，信道被判断为空，方可开始传输。由于非授权频段是多种技术或多个传输节点共享，因此这种基于竞争的接入方式导致信道可用时间的不确定性。目前可用于5G非授权通信系统的先听后说(Listen Before Talk，LBT)种类有以下三种：LBT类型1(LBT Cat 1)、不做任何CCA直接发送，必须是在已经获得信道的情况下在传输转换的间隔小于16us的情况下可以使用；LBT类型2(LBT Cat2)、进行25us的信道侦听，对特定信号获取信道可以使用，最大连续传输长度应该小于一定数值，例如1ms；LBT类型3(LBT Cat 4)、进行融合随机回退的信道侦听，对不同优先级参数设置不同，最后获得信道后可传输的最大长度也不同。
进一步地，为了保证终端在非授权频段的连续传输，网络设备可以在一个上行授权(Uplink grant，UL grant)给终端调度多个连续的时隙(slot)，或称为传输时间间隔(Transmission Timing Interval，TTI)，其中每个TTI共享同一套传输参数，但不同TTI是独立的传输块(Transport Blocks，TBS)以及混合自动重传请求(Hybrid Automatic Repeat Request，HARQ)进程标 识(process ID)。
当5G系统运行在包含多个LBT子带(subband)的宽带传输时，如大于20MHz在上行数据传输之前，终端需要在每个20MHz的子带上进行LBT，并且只能在成功的子带上进行传输。但是终端在收到UL授权后会按照下行控制信息(Downlink Control Information，DCI)指示来计算TBS大小并准备数据，当调度资源的一部分由于LBT失败而不能传输时，这部分数据需要被打孔(puncture)。如图1所示，终端在时隙1(slot#1)前LBT失败，原来映射到子带3(subband#3)上的数据在所有调度的TTI都不能传输，即对调度的多个TTI都进行打孔，那么这些TTI的数据可能都需要重传，大大降低了系统的传输效率。

请参见图2，图2示出本公开实施例可应用的一种无线通信系统的框图。无线通信系统包括终端21和网络设备22。其中，终端21也可以称作终端设备或者用户终端(User Equipment，UE)，终端21可以是手机、平板电脑(Tablet Personal Computer)、膝上型电脑(Laptop Computer)、个人数字助理(Personal Digital Assistant，PDA)、移动上网装置(Mobile Internet Device，MID)、可穿戴式设备(Wearable Device)或车载设备等终端侧设备，需要说明的是，在本公开实施例中并不限定终端21的具体类型。网络设备22可以是基站或核心网，其中，上述基站可以是5G及以后版本的基站(例如：gNB、5G NR NB等)，或者其他通信系统中的基站(例如：eNB、WLAN接入点、或其他接入点等)，其中，基站可被称为节点B、演进节点B、接入点、基收发机站(Base Transceiver Station，BTS)、无线电基站、无线电收发机、基本服务集(Basic Service Set，BSS)、扩展服务集(Extended Service Set，ESS)、B节点、演进型B节点(eNB)、家用B节点、家用演进型B节点、WLAN接入点、WiFi节点或所述领域中其他某个合适的术语，只要达到相同的技术效果，所述基站不限于特定技术词汇，需要说明的是，在本公开实 施例中仅以NR系统中的基站为例，但是并不限定基站的具体类型。
基站可在基站控制器的控制下与终端21通信，在各种示例中，基站控制器可以是核心网或某些基站的一部分。一些基站可通过回程与核心网进行控制信息或用户数据的通信。在一些示例中，这些基站中的一些可以通过回程链路直接或间接地彼此通信，回程链路可以是有线或无线通信链路。无线通信系统可支持多个载波(不同频率的波形信号)上的操作。多载波发射机能同时在这多个载波上传送经调制信号。例如，每条通信链路可以是根据各种无线电技术来调制的多载波信号。每个已调信号可在不同的载波上发送并且可携带控制信息(例如，参考信号、控制信道等)、开销信息、数据等。

本公开实施例提供了一种非授权频段的上行传输方法，应用于终端侧，如图3所示，该方法包括以下步骤：
步骤31：对调度资源进行侦听，得到相应的侦听结果。
本公开实施例的调度资源可以包括多个子带(subband)，如调度资源包括子带1(subband#1)、子带2(subband#2)、子带3(subband#3)和子带4(subband#4)。调度资源还可以包括多个时域传输单元(如时隙slot)，如 调度资源包括：时隙1(slot#1)、时隙2(slot#2)、时隙3(slot#3)和时隙4(slot#4)。其中，该调度资源可以是动态调度资源，也可以是半静态调度资源。终端在得到调度资源后，在通过调度资源发送信息之前需要对调度资源进行侦听。可选地，终端在调度资源的第一个时隙之前，对调度资源的多个子带分别进行侦听，得到每个子带各自的侦听结果。若终端对调度资源的第一个时隙进行侦听确定第一个时隙中所有子带均侦听失败，则终端继续对调度资源的第二个时隙进行侦听，直至某个时隙中至少有一个子带侦听成功，才开始通过调度资源进行上行传输。
步骤32：根据侦听结果，在调度资源中发送传输块。
终端在侦听到调度资源的某个时隙中至少有一个子带侦听成功的情况下，根据调度资源各个子带的侦听结果，确定待发送的传输块，并通过调度资源发送相应的传输块。根据对调度资源的侦听结果来发送传输块，使得传输块的传输更加灵活，可提高该场景下传输块的传输效率。
其中，步骤31之前还包括：接收用于指示调度资源的第一下行控制信息DCI。
其中，第一下行控制信息(Downlink Control Information，DCI)中携带有调度该调度资源的资源指示信息。
下面本公开实施例将进一步结合示例对如何根据侦听结果在调度资源中发送传输块的实现方式做进一步说明。值得说明的是步骤32的实现方式包括但不限于以下：
方式一、网络设备重新发送DCI来覆盖前面发送DCI的调度参数。
其中，该方式适用于非独立场景，步骤32包括：从网络设备侧接收第二下行控制信息DCI；其中，第二DCI中携带有更新的上行调度参数；根据第二DCI中更新的上行调度参数，在调度资源中发送传输块。也就是说，网络设备可以通过下发新的DCI来改变终端在调度资源内的上行调度参数。如图4所示，终端对调度资源的时隙1的子带1至4进行侦听，确定子带1、子带2和子带4可用，子带3不可用，终端在时隙1中按照第一DCI准备数据，即将数据映射至时隙1的子带1至子带4中，形成传输块(Transport Block，TB)1，但由于子带3不可用，因此终端在传输时，对子带3进行打孔。相应 地，网络设备按照第一DCI的上行调度参数来接收TB1。
其中，第二DCI是网络设备根据在调度资源中接收到的解调参考信号(De-Modulation Reference Signal，DMRS)触发的；也就是说，网络设备通过对之前传输slot的DMRS检测，得到终端侦听子带成功的信息，在另一载波上发送第二DCI来调整上行调度参数。以图4为例，网络设备在接收到TB1后，检测其DMRS确定子带3不可用，那么网络设备向终端发送第二DCI来调整后续调度资源的上行调度参数，如图4中所示，将调度资源中时隙2至4中的子带1、子带2和子带4作为调度资源。终端按照第二DCI来准备数据，即将数据映射至时隙2的子带1、子带2和子带4中，形成TB2；将数据映射至时隙3的子带1、子带2和子带4中，形成TB3；将数据映射至时隙4的子带1、子带2和子带4中，形成TB4。终端在传输时无需再对传输块进行打孔。相应地，网络设备按照第二DCI的上行调度参数来接收TB2、TB3和TB4。
或者，第二DCI是网络设备根据在调度资源中接收到的第一上行控制信息(Uplink Control Information，UCI)触发的，第一UCI携带有侦听结果。也就是说，终端在之前传输slot中的传输块中附带的第一UCI，网络设备得到第一UCI中可确定终端侦听子带成功的信息，然后在另一个载波发送第二DCI调整上行调度参数。以图4为例，网络设备在接收到TB1后，TB1中携带的第一UCI指示子带3不可用，那么网络设备向终端发送第二DCI来调整后续调度资源的上行调度参数，如图4中所示，将调度资源中时隙2至4中的子带1、子带2和子带4作为调度资源。终端按照第二DCI来准备数据，即将数据映射至时隙2的子带1、子带2和子带4中，形成TB2；将数据映射至时隙3的子带1、子带2和子带4中，形成TB3；将数据映射至时隙4的子带1、子带2和子带4中，形成TB4。终端在传输时无需再对传输块进行打孔。相应地，网络设备按照第二DCI的上行调度参数来接收TB2、TB3和TB4。
方式二、网络设备显示指示或者隐式约定终端，按照更新时间，来进行传输块的更新。
该方式下，终端根据侦听结果和第一DCI，在调度资源上发送传输块。具体地，第一DCI可以包括但不限于：调制与编码策略(Modulation and  Coding Scheme，MCS)指示信息(如MCS索引)、时域资源分配(Time Domain Resource Allocation，TDRA)指示信息、频域资源分配(Frequency Domain Resource Allocation，FDRA)指示信息、传输块缩放因子(scaling factor)和连续调度的时隙数目中的至少一项。
具体地，步骤32包括：根据侦听结果和第一DCI，按照更新时间，在调度资源中分别发送第一传输块和第二传输块；其中，更新时间与侦听结果相关。其中，本实施例中提及的更新时间可以携带于第一DCI中，或者，该更新时间还可以是根据终端能力确定的。
其中，在第一DCI不包括传输块缩放因子的情况下，第一传输块是根据MCS指示信息、TDRA指示信息和FDRA指示信息确定的。或者，在第一DCI包括传输块缩放因子的情况下，第一传输块是根据MCS指示信息、TDRA指示信息、FDRA指示信息和传输块缩放因子确定的。
以上介绍了第一传输块的映射规则，下面将进一步介绍第二传输块的映射规则，第二传输块是根据MCS指示信息、TDRA指示信息、FDRA指示信息和所述侦听结果确定的。
在该方式下，根据侦听结果和第一DCI，按照更新时间，在调度资源中分别发送第一传输块和第二传输块的步骤包括：在侦听结果指示调度资源的至少部分侦听成功的情况下，在调度资源的前(n+i-1)个时隙中，发送第一传输块；在调度资源的第n+i至第N个时隙中，发送第二传输块；其中，n为更新时间，i为调度资源中第一个侦听成功的时隙，N为调度资源所包含的时隙数，n、i和N均为整数。也就是说，在该方式下，终端在侦听到调度资源中有子带可用的情况下，按照第一个可用子带的时隙和更新时间，来分别发送第一传输块和第二传输块，第一传输块是更新前的传输块，第二传输块是更新后的传输块。
如图5所示，终端对调度资源的时隙1的子带1至4进行侦听，确定子带1、子带2和子带4可用，子带3不可用。假设N＝4，i＝1，n＝2，那么终端在调度资源的前(n+i-1＝2+1-1＝2)个时隙中，按照第一DCI准备数据，具体地，在第一DCI未指示传输块缩放因子时，终端按照第一DCI指示的MCS、TDRA和FDRA等计算第一传输块大小，如果第一DCI指示了缩放因子s，终端 按照第一DCI指示的MCS、TDRA、FDRA和缩放因子s等计算第一传输块大小，如TB1＝TB*s。终端按照确定的第一传输块的大小，将数据映射至时隙1的子带1至子带4中，形成TB1；将数据映射至时隙2的子带1至子带4中，形成传输块TB2。但由于子带3不可用，因此终端在传输时，对子带3进行打孔。相应地，网络设备按照第一DCI的上行调度参数来接收TB1和TB2。
进一步地，终端在调度资源的第n+i至第N个时隙，即第3和4个时隙中，按照侦听结果和第一DCI准备数据。具体地，终端根据侦听成功的子带情况和第一DCI中的资源指示来综合计算第二传输块的大小，终端按照确定的第二传输块的大小，将数据映射至时隙3的子带1、子带2和子带4中，形成TB3；将数据映射至时隙4的子带1、子带2和子带4中，形成TB4。终端在传输时无需再对传输块进行打孔。相应地，网络设备按照第一DCI的上行调度参数和侦听结果来接收TB3和TB4。具体地，网络设备在接收前需要预先判断哪些时隙和子带有数据传输，在调度资源的前(n+i-1)个时隙使用第一DCI指示的MCS和确定出的第一传输块大小进行解码，在后续的时隙使用第一DCI指示的MCS和确定出的第二传输块大小进行解码。
方式三、终端根据侦听结果自主调整调度资源的上行调度参数，并在传输块上携带专门用于指示调度资源的上行调度参数的UCI。
终端发送的传输块中携带有第二UCI，第二UCI包括：传输资源指示信息、用于指示是否打孔的指示信息、传输资源块缩放因子和下一个时隙中的传输块是否调整的指示信息中的至少一项。
其中，在第二UCI包括用于指示是否打孔的指示信息，且指示信息指示不打孔的情况下，传输块与侦听结果相关。具体地，在该情况下，传输块可根据配置的上行调度参数和侦听结果联合确定。
在第二UCI包括用于指示是否打孔的指示信息，且指示信息指示打孔的情况下，传输块与配置的上行调度参数相关。具体地，在该情况下，传输块可根据配置的上行调度参数确定。
进一步地，第二UCI中的传输资源指示信息用于指示：可用或不可用子带、更新的FDRA、更新的TDRA等。下一个时隙中传输块是否调整的指示信息指示未调整时，网络设备无需再解调下一个时隙中的第二UCI；指示调整 时，网络设备需要解调下一个时隙中的第二UCI，并按照第二UCI的指示来接收传输块。
该方式下，终端根据侦听结果自主确定调度资源上的上行调度参数。其中，步骤32包括：在侦听结果指示调度资源的至少部分侦听失败的情况下，在调度资源中分别发送第一传输块和第二传输块。其中，第二传输块和第一传输块的大小可以相同，也可以不同。也就是说，终端在调度资源上的至少部分侦听失败时，可自主决定是否调整调度资源的上行调度参数，若调整，则第二传输块的大小与第一传输块的大小不同；若不调整，则第二传输块的大小与第一传输块的大小相同。
其中，该方式下，第一传输块和第二传输块的大小确定方式可与方式二下的确定方式相同。但是在该方式下，传输块缩放因子可以由终端自主确定和选择。第一传输块是根据MCS指示信息、TDRA指示信息和FDRA指示信息确定的，或者，第一传输块是根据MCS指示信息、TDRA指示信息、FDRA指示信息和传输块缩放因子确定的。第二传输块与侦听结果相关，具体地第二传输块可根据MCS指示信息、TDRA指示信息、FDRA指示信息和侦听结果联合确定的。
如图6所示，终端对调度资源的时隙1的子带1至4进行侦听，确定子带1、子带2和子带4可用，子带3不可用。终端可根据能力决定传输改变的时间点，并通过第二UCI来通知网络设备数据传输的更新。例如终端可自主确定在调度资源的时隙1中，按照第一DCI准备数据，具体地，终端按照第一DCI指示的MCS、TDRA和FDRA等计算第一传输块大小，或者，终端按照第一DCI指示的MCS、TDRA和FDRA等以及自主确定或选择的缩放因子s来计算第一传输块大小，如TB1＝TB*s。终端按照确定的第一传输块的大小，将数据映射至时隙1的子带1至子带4中，形成TB1。进一步地，终端在后续调度资源中，即第2至4个时隙中，按照侦听结果和第一DCI准备数据。具体地，终端根据侦听成功的子带情况和第一DCI中的资源指示来综合计算第二传输块的大小，终端按照确定的第二传输块的大小，将数据映射至时隙2的子带1、子带2和子带4中，形成TB2；将数据映射至时隙3的子带1、子带2和子带4中，形成TB3；将数据映射至时隙4的子带1、子带2和子带4中， 形成TB4。终端在传输时无需再对传输块进行打孔。
由于该方式下，在调度资源中发送传输块的上行调度参数是终端根据侦听结果自主确定，因此终端按照上述方式发送第一传输块和第二传输块时，在第一传输块或第二传输块中携带有第二UCI，其中，终端根据侦听结果和终端能力在不同时隙上配置不同的第二UCI映射至特定位置，以指示相应时隙上的数据准备情况，即传输块。第二UCI包括：传输资源指示信息、用于指示是否打孔的指示信息、传输资源块缩放因子和下一个时隙中的传输块是否调整的指示信息中的至少一项。其中，传输资源指示信息用于指示可用或不可用子带、更新的FDRA、更新的TDRA等。下一个时隙中传输块是否调整的指示信息指示未调整时，网络设备无需再解调下一个时隙中的第二UCI；指示调整时，网络设备需要解调下一个时隙中的第二UCI，并按照第二UCI的指示来接收传输块。
方式四、终端根据侦听结果进行时隙聚合(slot aggregation)，通过调度资源发送时隙聚合后的传输块。
该方式下，终端根据侦听结果进行时隙聚合，将一个时隙的数据速率匹配(rate matching)到多个时隙中进行传输，这样即使对某个时隙中的部分子带不可用时，按照原速率匹配准备数据时，也不会导致资源不够用。具体地，步骤32包括：在侦听结果指示调度资源中的至少部分侦听失败的情况下，对调度资源进行时隙聚合；发送时隙聚合后的传输块。
该方式下，终端按照第一DCI的指示来计算传输块的大小并准备数据。若终端侦听调度资源时确定调度资源中至少部分侦听失败时，终端进行时隙聚合，时隙聚合采用的时隙聚合参数可以显式的指示在第三UCI中或者按照既定规则进行计算，以按照既定规则进行计算为例，例如第一DCI指示调度的物理资源块(Physical Resource Block，PRB)数为m1，侦听结果指示调度资源中可用的PRB数为m2，则时隙聚合参数可以为[m1/m2]。
以终端自主确定聚合参数为例，如图7所示，终端对调度资源的时隙1的子带1至4进行侦听，确定子带1、子带2和子带4可用，子带3不可用。终端采用时隙聚合参数为2进行时隙聚合，即每两个时隙进行聚合。终端在调度资源中按照时隙聚合后的传输块大小准备数据。具体地，终端将数据映 射至时隙1和时隙2的子带1、子带2和子带4中，形成TB1；将数据映射至时隙3和时隙4的子带1、子带2和子带4中，形成TB2。
其中，时隙聚合采用的时隙聚合参数可以是终端自主确定的，该场景下终端发送的传输块中携带有第三UCI，第三UCI包括：时隙聚合采用的时隙聚合参数。
进一步地，时隙聚合参数除了可以终端自主确定、按照既定规则确定外，时隙聚合采用的时隙聚合参数还可以是预定义的，如协议约定。或者，该时隙聚合参数还可以是网络设备配置给终端的，如网络设备通过无线资源控制(Radio Resource Control，RRC)信令配置，或通过广播信令配置等。
方式五、终端在调度资源的多个时隙内进行传输块的重传，并在传输块中携带专门用于指示重传的UCI。
该方式下，终端根据侦听结果，自主确定是否在调度资源内进行传输块的重传，以降低数据传输时延。具体地，步骤32包括：在侦听结果指示调度资源的至少部分侦听失败的情况下，在调度资源的第一部分资源中进行传输块的初传；在调度资源的第二部分资源中进行传输块的重传。
在该方式下，若终端侦听调度资源时确定调度资源中至少部分侦听失败时，终端在调度资源的部分资源内进行传输块的初传，在另一部分资源内进行传输块的重传。如图8所示，终端对调度资源的时隙1的子带1至4进行侦听，确定子带1、子带2和子带4可用，子带3不可用。终端在调度资源中按照第一DCI准备数据，但由于子带3不可用，因此终端在传输时，对子带3进行打孔，这时会导致传输的数据不完整。为降低这部分数据的传输时延，终端可将数据映射至时隙1的子带1至子带4中，形成TB1；将数据映射至时隙2的子带1至子带4中，形成TB2。并将TB1的重传数据映射至时隙3的子带1至子带4中；将TB2的重传数据映射至时隙4的子带1至子带4中。进一步地，为了保证数据完整性，传输块初传和重传过程中所采用的冗余版本(Redundancy Version，RV)不同，如图8所示，初传采用RV0，重传采用RV2。
在该场景下，由于是终端自主确定是否进行传输块的重传，为保证网络设备正确解调，终端发送的传输块中携带有第四UCI，第四UCI包括：混合 自动重传请求(Hybrid Automatic Repeat Request，HARQ)标识信息和冗余版本标识信息中的至少一项。
本公开实施例的非授权频段的上行传输方法中，终端在调度资源包括多个时隙的非授权频段传输场景下，可根据对调度资源的侦听结果来发送传输块，传输块的传输更加灵活，可提高该场景下传输块的传输效率。

以上实施例从终端侧介绍了本公开的非授权频段的上行传输方法，下面本实施例将结合附图对网络设备侧的非授权频段的上行传输方法做进一步介绍。
如图11所示，本公开实施例的非授权频段的上行传输方法，应用于网络设备侧，该方法包括以下步骤：
步骤111：在调度资源上，接收传输块。
其中，该传输块与终端对调度资源的侦听结果相关。其中，终端在调度资源的第一个时隙之前，对调度资源的多个子带分别进行侦听，得到每个子带各自的侦听结果。若终端对调度资源的第一个时隙进行侦听确定第一个时隙中所有子带均侦听失败，则终端继续对调度资源的第二个时隙进行侦听，直至某个时隙中至少有一个子带侦听成功，才开始通过调度资源进行上行传输。进一步地，终端在侦听到调度资源的某个时隙中至少有一个子带侦听成功的情况下，根据调度资源各个子带的侦听结果，确定待发送的传输块，并通过调度资源发送相应的传输块。根据对调度资源的侦听结果来发送传输块，使得传输块的传输更加灵活，可提高该场景下传输块的传输效率。
在步骤111之前还包括：网络设备向终端发送用于指示调度资源的第一下行控制信息DCI。
其中调度资源可以包括多个子带，如调度资源包括子带1、子带2、子带3和子带4。调度资源还可以包括多个时域传输单元(如时隙slot)，如调度 资源包括：时隙1、时隙2、时隙3和时隙4。第一DCI中携带有调度该调度资源的资源指示信息。
下面本公开实施例将结合上述终端侧传输块的发送方式，对网络设备侧的解调行为做进一步说明。
对应于终端侧方式一，网络设备可以通过下发新的DCI来改变终端在调度资源内的上行调度参数。如在第二DCI中携带有更新的上行调度参数。
具体地，在步骤111之前，网络设备还根据在调度资源中接收到的解调参考信号DMRS，向终端发送第二DCI；也就是说，网络设备通过对之前传输slot的DMRS检测，得到终端侦听子带成功的信息，在另一载波上发送第二DCI来调整上行调度参数。
或者，在步骤111之前，网络设备根据在调度资源中接收到的第一上行控制信息UCI，向终端发送第二DCI，第一UCI携带有终端对调度资源的侦听结果。也就是说，终端在之前传输slot中的传输块中附带的第一UCI，网络设备得到第一UCI中可确定终端侦听子带成功的信息，然后在另一个载波发送第二DCI调整上行调度参数。
对应于方式二，网络设备发送给终端的第一DCI包括：调制与编码策略MCS指示信息、时域资源分配TDRA指示信息、频域资源分配FDRA指示信息、传输块缩放因子、连续调度的时隙数目和传输块的更新时间中的至少一项。
在该方式下，终端和网络设备预先确定了终端更新传输块的规则：终端根据侦听结果和第一DCI，按照更新时间，在调度资源中分别发送第一传输块和第二传输块，更新时间与侦听结果相关。例如，终端在侦听结果指示调度资源的至少部分侦听成功的情况下，在调度资源的前(n+i-1)个时隙中，发送第一传输块；在调度资源的第n+i至第N个时隙中，发送第二传输块；其中，n为更新时间，i为调度资源中第一个侦听成功的时隙，N为调度资源所包含的时隙数，n、i和N均为整数。相应地，网络设备在前(n+i-1)个时隙，按照第一传输块来解调信息；在第n+i至第N个时隙，按照第二传输块来解调信息。
对应于方式三、网络设备接收到的传输块携带有第二UCI，第二UCI包括：传输资源指示信息、用于指示是否打孔的指示信息、传输资源块缩放因 子和下一个时隙中的传输块是否调整的指示信息中的至少一项。
其中，在该方式下，网络设备先进行第二UCI的解码，读取第二UCI后，按照第二UCI的指示对数据进行相应的解码。步骤111之后，网络设备在第二UCI中的指示信息指示打孔的情况下，根据对调度资源的上行调度参数(如第一DCI指示的上行调度参数)，对传输块进行解调。例如，根据MCS指示信息、TDRA指示信息和FDRA指示信息确定传输块的大小。或者，根据MCS指示信息、TDRA指示信息、FDRA指示信息和传输块缩放因子确定传输块的大小。
或者，步骤111之后，网络设备在第二UCI中的指示信息指示不打孔的情况下，根据终端对调度资源的侦听结果，对传输块进行解调。具体地，在该场景下，网络设备可根据对调度资源的上行调度参数和侦听结果联合，对传输块进行解调。例如，根据MCS指示信息、TDRA指示信息、FDRA指示信息和侦听结果确定传输块的大小。
对应于方式四，终端根据侦听结果进行时隙聚合，将一个时隙的数据速率匹配到多个时隙中进行传输，相应地，网络设备在步骤111之后还包括：对调度资源进行时隙聚合；对时隙聚合后的传输块进行解调。
其中，时隙聚合采用的时隙聚合参数可以通过接收到的传输块确定，具体地，传输块中携带有第三UCI，第三UCI包括：时隙聚合采用的时隙聚合参数；或者，时隙聚合采用的时隙聚合参数是预定义的。或者，该时隙聚合参数还可以是网络设备配置给终端的。或者，时隙聚合参数还可以是按照既定规则确定的。
对应于方式五，若终端侦听调度资源时确定调度资源中至少部分侦听失败时，终端在调度资源的部分资源内进行传输块的初传，在另一部分资源内进行传输块的重传。由于是终端自主确定是否进行传输块的重传，网络设备可根据接收到的传输块确定终端是否进行了重传。可选地，终端发送的传输块中携带有第四UCI，第四UCI包括：混合自动重传请求HARQ标识信息和冗余版本标识信息中的至少一项。相应地，在步骤111之后，网络设备根据第四UCI，合并传输块。进一步地，网络设备根据第一DCI的指示进行解码，并按照第四UCI的指示进行合并。
本公开实施例的非授权频段的上行传输方法中，网络设备为终端调度包 括多个时隙的调度资源，并通过调度资源接收传输块，其中，该传输块与终端对调度资源的侦听结果相关，这样传输块的传输更加灵活，可提高非授权频段传输场景下传输块的传输效率。
以上实施例介绍了不同场景下的非授权频段的上行传输方法，下面将结合附图对与其对应的网络设备做进一步介绍。
