具体实施方式
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行描述，显然，所描述的实施例是本申请一部分实施例，而不是全部的实施例。针对本申请中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。
本申请实施例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、先进的长期演进(Advanced long term evolution，LTE-A)系统、新无线(New Radio，NR)系统、NR系统的演进系统、免授权频谱上的LTE(LTE-based access to unlicensed spectrum，LTE-U)系统、免授权频谱上的NR(NR-based access to unlicensed spectrum，NR-U)系统、通用移动通信系统(Universal Mobile Telecommunication System，UMTS)、无线局域网(Wireless Local Area Networks，WLAN)、无线保真(Wireless Fidelity，WiFi)、下一代通信系统或其他通信系统等。
通常来说，传统的通信系统支持的连接数有限，也易于实现，然而，随着通信技术的发展，移动通信系统将不仅支持传统的通信，还将支持例如，设备到设备(Device to Device，D2D)通信，机器到机器(Machine to Machine，M2M)通信，机器类型通信(Machine Type Communication，MTC)，以及车辆间(Vehicle to Vehicle，V2V)通信等，本申请实施例也可以应用于这些通信系统。
可选地，本申请实施例中的通信系统可以应用于载波聚合(Carrier Aggregation，CA)场景，也可以应用于双连接(Dual Connectivity，DC)场景，还可以应用于独立(Standalone，SA)布网场景。
本申请实施例对应用的频谱并不限定。例如，本申请实施例可以应用于授权频谱，也可以应用于免授权频谱。
示例性的，本申请实施例应用的通信系统100如图1所示。该通信系统100可以包括网络设备110，网络设备110可以是与终端设备120(或称为通信终端、终端)通信的设备。网络设备110可以为特定的地理区域提供通信覆盖，并且可以与位于该覆盖区域内的终端设备进行通信。
图1示例性地示出了一个网络设备和两个终端设备，可选地，该通信系统100可以包括多个网络设备并且每个网络设备的覆盖范围内可以包括其它数量的终端设备，本申请实施例对此不做限定。
可选地，该通信系统100还可以包括网络控制器、移动管理实体等其他网络实体，本申请实施例对此不作限定。
应理解，本申请实施例中网络/系统中具有通信功能的设备可称为通信设备。以图1示出的通信系统100为例，通信设备可包括具有通信功能的网络设备110和终端设备120，网络设备110和终端设备120可以为上文所述的具体设备，此处不再赘述；通信设备还可包括通信系统100中的其他设备，例如网络控制器、移动管理实体等其他网络实体，本申请实施例中对此不做限定。
应理解，本文中术语“系统”和“网络”在本文中常被可互换使用。本文中术语“和/或”，仅仅是一种描述关联对象的关联关系，表示可以存在三种关系，例如，A和/或B，可以表示：单独存在A，同时存在A和B，单独存在B这三种情况。另外，本文中字符“/”，一般表示前后关联对象是 一种“或”的关系。
本申请实施例结合终端设备和网络设备描述了各个实施例，其中：终端设备也可以称为用户设备(User Equipment，UE)、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等。终端设备可以是WLAN中的站点(STAION，ST)，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)设备、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、可穿戴设备以及下一代通信系统，例如，NR网络中的终端设备或者未来演进的公共陆地移动网络(Public Land Mobile Network，PLMN)网络中的终端设备等。
作为示例而非限定，在本申请实施例中，该终端设备还可以是可穿戴设备。可穿戴设备也可以称为穿戴式智能设备，是应用穿戴式技术对日常穿戴进行智能化设计、开发出可以穿戴的设备的总称，如眼镜、手套、手表、服饰及鞋等。可穿戴设备即直接穿在身上，或是整合到用户的衣服或配件的一种便携式设备。可穿戴设备不仅仅是一种硬件设备，更是通过软件支持以及数据交互、云端交互来实现强大的功能。广义穿戴式智能设备包括功能全、尺寸大、可不依赖智能手机实现完整或者部分的功能，例如：智能手表或智能眼镜等，以及只专注于某一类应用功能，需要和其它设备如智能手机配合使用，如各类进行体征监测的智能手环、智能首饰等。
网络设备可以是用于与移动设备通信的设备，网络设备可以是WLAN中的接入点(Access Point，AP)，GSM或CDMA中的基站(Base Transceiver Station，BTS)，也可以是WCDMA中的基站(NodeB，NB)，还可以是LTE中的演进型基站(Evolutional Node B，eNB或eNodeB)，或者中继站或接入点，或者车载设备、可穿戴设备以及NR网络中的网络设备或者基站(gNB)或者未来演进的PLMN网络中的网络设备等。
在本申请实施例中，网络设备为小区提供服务，终端设备通过该小区使用的传输资源(例如，频域资源，或者说，频谱资源)与网络设备进行通信，该小区可以是网络设备(例如基站)对应的小区，小区可以属于宏基站，也可以属于小小区(Small cell)对应的基站，这里的小小区可以包括：城市小区(Metro cell)、微小区(Micro cell)、微微小区(Pico cell)、毫微微小区(Femto cell)等，这些小小区具有覆盖范围小、发射功率低的特点，适用于提供高速率的数据传输服务。
应理解，NR Rel 16对PUSCH重复做了增强，放松了一些限制条件，即每个时隙内可以有一个或多个PUSCH，且PUSCH所在的时域资源可以不同，如图2和图3所示。图2包含了PUSCH跨时隙的情况，图3包含了一个时隙内包括多个PUSCH的情况。由于不再对应用场景做限制，数据可以做到即时调度，进而降低了数据传输时延。
需要说明的是，在图3中，D表示时隙内的下行符号，F表示时隙内的灵活符号，U表示时隙内的上行符号。
但是当限制被放松后，会出现一个PUSCH分裂成两个或多个PUSCH的情况。如图2所示，当一个PUSCH跨时隙会分裂为两个独立的PUSCH，即传输独立的传输块(Transport block，TB)。如图3所示，当一个PUSCH遇到下行和灵活资源，会自动拆分，拆分后的两个PUSCH传输独立的TB。
PUSCH repetition拆分后可能形成持续时间较短的PUSCH repetition，这些PUSCH repetition太短以至于无法实现有效传输。对于这些持续时间较短的PUSCH repetition，一种方式是短PUSCH repetition不发送，这样会造成资源浪费，如图4所示。另外一种方式是短PUSCH repetition与相邻的PUSCH repetition接连，形成一个新的长的PUSCH repetition，此时会导致DMRS不对齐，干扰DMRS检测性能，如图5所示。
基于上述问题，本申请提出一种PUSCH repetition级联和丢弃组合的方式，同时，DMRS映射和TB映射按照不同的PUSCH repetition资源假设进行，既可以提高系统效率，避免资源浪费，又可以避免DMRS和数据碰撞，影响正常数据解调。
以下详细阐述本申请针对上述技术问题而设计的技术方案。
图6是根据本申请实施例的无线通信方法200的示意性流程图，如图6所示，该方法200可以包括如下内容中的部分或全部：
S210，终端设备确定至少一个数据TB映射的第一信道，其中，该第一信道是由至少两个第二信道组合得到的；
S220，该终端设备在该第一信道上传输该至少一个数据TB。
至少一个数据TB映射的第一信道，也就是说，数据TB按照组合之后的信道进行映射。
可选地，在本申请实施例中所述的信道包括上行信道和/或下行信道。即该第一信道可以是上行信道，也可以是下行信道。该第二信道可以是上行信道，也可以是下行信道。
但需要注意的是，该第一信道与该第二信道为同一类型的信道，即该第一信道与该第二信道同为下行信道，或者，该第一信道与该第二信道同为上行信道。
例如，上行信道为PUSCH或物理上行控制信道(Physical Uplink Control Channel，PUCCH)。
又例如，下行信道为物理下行共享信道(Physical Downlink Shared Channel，PDSCH)或物理下行控制信道(Physical Downlink Control Channel，PDCCH)。
在该第一信道为上行信道时，S220具体可以是，该终端设备在该第一信道上发送该至少一个数据TB。在该第一信道为下行信道时，S220具体可以是，该终端设备在该第一信道上接收该至少一个数据TB。
需要说明的是，在本申请实施例中，两个信道组合也可以理解为是两个信道级联。
可选地，在本申请实施例中，该至少两个第二信道中的至少一个第二信道由第三信道分裂得到。
例如，第三信道跨时隙边界分裂之后形成该至少一个第二信道。
又例如，第三信道自动分裂(拆分)之后形成该至少一个第二信道。
需要说明的是，该第三信道与该第二信道为同一类型的信道，即该第三信道与该第二信道同为下行信道，或者，该第三信道与该第二信道同为上行信道。
可选地，在本申请实施例中，该第三信道可以是网络设备配置的。
例如，终端设备接收网络设备发送的第一配置信息，该第一配置信息用于配置至少一个第三信道。
可选地，该至少一个第三信道可以是第三信道重复(repetition)。
例如，该第三信道重复次数为4次，即为4个第三信道，这4个第三信道在时域上连续分布。
可选地，网络设备可以通过上行授权(uplink grant，UL grant)配置PUSCH repetition的资源。
可选地，在本申请实施例中，该第二信道是否支持组合是可以配置的。同理，该第二信道是否支持丢弃是可以配置的。
例如，终端设备接收网络设备发送的第一指示信息，该第一指示信息用于指示是否支持该第二信道进行组合和/或丢弃。
可选地，在本申请实施例中，也可以默认该第二信道支持组合和丢弃。
可选地，在该第二信道支持组合和/或丢弃的情况下，该终端设备根据第一规则和第二规则，判断是否对该第二信道进行组合或者丢弃。
该第一规则为以下中的至少一种：
该第二信道时域长度是否小于或者等于第一门限值，该第二信道上待传输数据的等效码率(Code Rate)是否大于或者等于k，k为正数，该第二信道是否具有数据传输资源。
该第二规则为该第二信道是否存在相邻的第二信道。
可选地，该第一门限值为预配置的，或者，该第一门限值为网络设备配置的。
例如，k为1或者0.93。
需要说明的是，等效码率可用于确定可用的数据传输资源，也可以用于确定调制方式和比特。
具体地，若满足以下情况中的至少一种，该终端设备确定该第二信道满足该第一规则：
该第二信道时域长度小于或者等于第一门限值，该第二信道上待传输数据的等效码率大于或者等于k，第二信道不具有数据传输资源。
具体地，若该第二信道存在相邻的第二信道，该终端设备确定该第二信道满足该第二规则。
可选地，在本申请实施例中，该第一规则和/或该第二规则可以是网络设备通过无线资源控制(Radio Resource Control，RRC)信令配置的。
例如，在该第一规则中，该第一门限值的取值可以是1个符号至4个符号。
可选地，在本申请实施例中，该终端设备具体可以通过如下方式判断是否对所述第二信道进行组合或者丢弃：
若该第二信道不满足该第一规则，该终端设备判断不对该第二信道进行组合或者丢弃；和/或，
若该第二信道满足该第一规则且不满足该第二规则，该终端设备判断对该第二信道进行丢弃；和/或，
若该第二信道满足该第一规则且满足该第二规则，该终端设备判断对该第二信道进行组合；和/或，
若该第二信道不满足该第一规则，该终端设备在该第二信道上独立传输数据TB。
可选地，在本申请实施例中，在该第二信道支持组合和/或丢弃的情况下，该终端设备将该第二信道与其相邻的第二信道进行组合。

可选地，该参考信号包括前置(front loaded)解调参考信号(Demodulation Reference Signal，DMRS)和/或附加(additional)DMRS。
可选地，在本申请实施例中，在上述信道为PUSCH重复的情况下，网络设备向终端设备发送PUSCH重复参数；终端设备可以根据该PUSCH重复参数，发送上行数据。
因此，在本申请实施例中，终端设备可以在至少两个第二信道组合得到的第一信道上传输至少一个数据TB，从而可以提高系统效率，避免资源浪费。
以下以上述信道为PUSCH，且网络设备为终端设备配置PUSCH重复资源为例，并结合具体实施例详细阐述本申请方案。
可选地，作为实施例一，
网络设备为终端设备配置PUSCH的重复次数为4次(4个第三信道)，第一个PUSCH重复的时域位置为第n个时隙的第5个符号-第12个符号，后续的PUSCH重复在时域上紧接着前一个PUSCH重复资源，因此，4次PUSCH重复(4个第三信道)的时域资源可以如图7中的a所示。此外，由于第二个PUSCH重复跨时隙边界，第二个PUSCH重复在时域上被分裂为部分A(2个符号)和部分B(6个符号)(2个第二信道)，4次PUSCH重复(4个第三信道)被分裂为5次PUSCH重复(5个第二信道)，如图7中的b所示。假设级联判决门限(ConcatenationThrethold)为3个符号(symbol)，由于该部分A为2个符号，小于ConcatenationThrethold，则该部分A与前面一个PUSCH重复进行级联(形成第一信道)；由于该部分B为6个符号，大于ConcatenationThrethold，则该部分B不与后面一个PUSCH重复进行级联，如图7中的c所示。DMRS和TB按照级联后的PUSCH重复进行映射，如图7中的c所示。
因此，在实施例一中，级联动作提高了系统效率，避免丢弃造成的浪费。同时设置门限值的级联，既可以实现短PUSCH重复级联，提高系统效率，又可以避免长PUSCH重复级联，降低处理时延或提升码率。进一步地，通过PUSCH repetition长度作为判决门限级联判决门限，既提高系统效率，避免丢弃导致的资源浪费。
可选地，作为实施例二，
网络设备为终端设备配置PUSCH的重复次数为4(4个第三信道)，第一个PUSCH重复的时域位置为第n个时隙的第13个符号-第n+1个时隙的第6个符号，后续的PUSCH重复在时域上紧接着前一个PUSCH重复资源，因此，可知4次PUSCH重复(4个第三信道)的时域资源可以如图8中的a所示。此外，由于第一个PUSCH重复和第四个PUSCH重复跨时隙边界，第一个PUSCH重复在时域上被分裂为部分A(2个符号)和部分B(6个符号)(2个第二信道)，第四个PUSCH重复在时域上被分裂为部分C(6个符号)和部分D(2个符号)(2个第二信道)，4次PUSCH重复(4个第三信道)被分裂为6次PUSCH重复(6个第二信道)，如图8中的b所示。假设级联判决门限为3个符号，由于该部分A为2个符号，小于级联判决门限，但由于前面没有可以级联的PUSCH重复，则该部分A丢弃；由于该部分B为6个符号，大于级联判决门限，则该部分B不与后面一个PUSCH重复进行级联；由于该部分C为6个符号，大于级联判决门限，则该部分C不与前面一个PUSCH重复进行级联；由于该部分D为2个符号，小于级联判决门限，但由于后面没有可以级联的PUSCH重复，则该部分D丢弃，如图8中的c所示。DMRS和TB按照级联后的PUSCH重复进行映射，如图8中的c所示。
因此，在实施例二中，丢弃动作避免了DMRS和数据不对齐造成的干扰。进一步地，通过PUSCH repetition长度作为判决门限级联判决门限，既提高系统效率，避免丢弃导致的资源浪费。对于无级联条件的PUSCH repetition放弃级联，既不会造成显著的资源浪费，也可以避免DMRS和数据干扰，影响正常数据的解调。
可选地，图9示出了4个UE的PUSCH repetition对比图，4个UE的PUSCH repetition在时频域上有重叠，且时域上依次退后一个PUSCH repetition的位置。从图9可以看出，基于上述实施例一和实施例二中的规则进行PUSCH repetition级联/丢弃后，无DMRS与数据碰撞问题。
可选地，作为实施例三，
网络设备为终端设备配置PUSCH的重复次数为4次(4个第三信道)，第一个PUSCH重复的时域位置为第n个时隙的第9个符号-第n+1个时隙的第2个符号，后续的PUSCH重复在时域上紧接着前一个PUSCH重复资源，因此，可知4次PUSCH重复(4个第三信道)的时域资源，如图10中的a所示。此外，由于第一个PUSCH重复和第三个PUSCH重复跨时隙边界，第一个PUSCH重复在时域上被分裂为部分A(6个符号)和部分B(2个符号)(2个第二信道)，第三个PUSCH重复在时域上被分裂为部分C(4个符号)和部分D(4个符号)(2个第二信道)，4次PUSCH重复(4个 第三信道)被分裂为6次PUSCH重复(6个第二信道)，如图10中的b所示。DMRS按照分裂后的PUSCH重复进行映射，如图10中的b所示。分裂后的PUSCH重复与相邻的PUSCH重复级联，具体地，由于该部分A无相邻的PUSCH重复，该部分A作为独立的PUSCH重复，该部分B与后面一个PUSCH重复进行级联(形成第一信道)，该部分C与前面一个PUSCH重复进行级联(形成第一信道)，该部分D与后面一个PUSCH重复进行级联(形成第一信道)，形成级联PUSCH重复，同时一个TB映射在一个级联PUSCH重复中，如图10中的c所示。
因此，在实施例三中，根据分裂后的PUSCH repetition插入DMRS，保证不同多个PUSCH repetition之间DMRS对齐；根据级联后的PUSCH repetition映射TB，避免了孤立(orphan)符号出现，提高了传输效率。
可选地，作为实施例四，
网络设备为终端设备配置PUSCH的重复次数为4次(4个第三信道)，第一个PUSCH重复的时域位置为第n+1个时隙的第3个符号-第n+1个时隙的第10个符号，后续的PUSCH重复在时域上紧接着前一个PUSCH重复资源，因此，可知4次PUSCH重复(4个第三信道)的时域资源，如图11中的a所示。此外，由于第二个PUSCH重复和第四个PUSCH重复跨时隙边界，第二个PUSCH重复在时域上被分裂为部分A(4个符号)和部分B(4个符号)(2个第二信道)，第四个PUSCH重复在时域上被分裂为部分C(2个符号)和部分D(6个符号)(2个第二信道)，4次PUSCH重复(4个第三信道)被分裂为6次PUSCH重复(6个第二信道)，如图11中的b所示。DMRS按照分裂后的PUSCH重复进行映射，如图11中的b所示。分裂后的PUSCH重复与相邻的PUSCH重复级联，具体地，该部分A与前面一个PUSCH重复进行级联(形成第一信道)，该部分B与后面一个PUSCH重复进行级联(形成第一信道)，该部分C与前面一个PUSCH重复进行级联(形成第一信道)，由于该部分D无相邻的PUSCH重复，该部分D作为独立的PUSCH重复，形成级联PUSCH重复，同时一个TB映射在一个级联PUSCH重复中，如图11中的c所示。
因此，在实施例四中，DMRS映射参考分裂后的PUSCH重复，保证DMRS总是对齐的，保证了DMRS解调性能，以及DMRS总是在PUSCH重复前端，提高检测速度。进一步地，根据级联后的PUSCH repetition映射TB，避免了孤立(orphan)符号出现，提高了传输效率。
图12示出了4个UE的PUSCH repetition对比图，4个UE的PUSCH repetition在时频域上有重叠，且时域上依次退后一个PUSCH repetition的位置。从图12可以看出，基于上述实施例三和实施例四中的规则进行PUSCH repetition级联/丢弃后，无DMRS与数据碰撞问题。
可选地，作为实施例五，
网络设备为终端设备配置PUSCH的重复次数为4次(4个第三信道)，第一个PUSCH重复的时域位置为第n个时隙的第9个符号-第n+1个时隙的第2个符号，后续的PUSCH重复在时域上紧接着前一个PUSCH重复资源，因此，可知4次PUSCH重复(4个第三信道)的时域资源，DMRS按照初始的PUSCH重复(分裂之前的PUSCH重复)进行映射，其中DMRS资源是网络设备配置的，如图13中的a所示。此外，由于第一个PUSCH重复和第三个PUSCH重复跨时隙边界，第一个PUSCH重复在时域上被分裂为部分A(6个符号)和部分B(2个符号)(2个第二信道)，第三个PUSCH重复在时域上被分裂为部分C(4个符号)和部分D(4个符号)(2个第二信道)，4次PUSCH重复(4个第三信道)被分裂为6次PUSCH重复(6个第二信道)。分裂后的PUSCH重复与相邻的PUSCH重复级联，具体地，由于该部分A无相邻的PUSCH重复，该部分A作为独立的PUSCH重复，该部分B与后面一个PUSCH重复进行级联(形成第一信道)，该部分C与前面一个PUSCH重复进行级联(形成第一信道)，该部分D与后面一个PUSCH重复进行级联(形成第一信道)，形成级联PUSCH重复，同时一个TB映射在一个级联PUSCH重复中，如图13中的b所示。
因此，在实施例五中，DMRS映射参考初始PUSCH重复，保证DMRS总是对齐的，保证了DMRS解调性能，与上述实施例四相比，DMRS开销较少。进一步地，根据级联后的PUSCH repetition映射TB，避免了orphan符号出现，提高了传输效率。
可选地，作为实施例六，
网络设备为终端设备配置PUSCH的重复次数为4次(4个第三信道)，第一个PUSCH重复的时域位置为第n+1个时隙的第3个符号-第n+1个时隙的第10个符号，后续的PUSCH重复在时域上紧接着前一个PUSCH重复资源，因此，可知4次PUSCH重复(4个第三信道)的时域资源，DMRS按照初始的PUSCH重复(分裂之前的PUSCH重复)进行映射，其中DMRS资源是网络设备配置的，如图14中的a所示。对于最后一个分裂的PUSCH重复，由于没有相邻的PUSCH重复可以级联，则作为一个独立的PUSCH重复，对于这一独立的PUSCH重复，也插入DMRS，如图14中的b所示。此外，由于第二个PUSCH重复和第四个PUSCH重复跨时隙边界，第二个PUSCH重复在时域上被分 裂为部分A(4个符号)和部分B(4个符号)(2个第二信道)，第四个PUSCH重复在时域上被分裂为部分C(2个符号)和部分D(6个符号)(2个第二信道)，4次PUSCH重复(4个第三信道)被分裂为6次PUSCH重复(6个第二信道)。分裂后的PUSCH重复与相邻的PUSCH重复级联，具体地，该部分A与前面一个PUSCH重复进行级联(形成第一信道)，该部分B与后面一个PUSCH重复进行级联(形成第一信道)，该部分C与前面一个PUSCH重复进行级联(形成第一信道)，由于该部分D无相邻的PUSCH重复，该部分D作为独立的PUSCH重复，形成级联PUSCH重复，同时一个TB映射在一个级联PUSCH重复中，如图14中的b所示。
因此，在实施例六中，DMRS映射参考初始PUSCH重复，保证DMRS总是对齐的，保证了DMRS解调性能，与上述实施例四相比，DMRS开销较少。进一步地，根据级联后的PUSCH repetition映射TB，避免了orphan符号出现，提高了传输效率。
