本申请实施例涉及通信领域,并且更具体地,涉及数据传输的方法、终端设备和网络设备。
背景技术
在将新无线(New Radio,NR)技术应用于免授权载波上时,由于NR支持的载波带宽最大能到400MHz,可能出现信道检测带宽与载波带宽/数据传输带宽不一致的情况,例如,可能存在信道检测带宽为20MHz,终端设备被调度的数据传输带宽为40MHz,其中,终端设备被调度的40MHz带宽中只有20MHz的信道可以使用的情况。在这种情况下,如何进行上行数据传输是一项值得研究的问题。
发明内容
本申请实施例提供了一种数据传输的方法、终端设备和网络设备,能够在信道检测带宽与系统的载波带宽或数据传输带宽不一致的情况下,进行上行数据传输,减小终端设备进行数据传输的时延或提高频谱的资源利用效率。

该终端设备通过信道检测确定该第一时频资源中的至少部分资源不能够使用,该终端设备不通过该第一时频资源向该网络设备发送该第一数据。
因此,在本申请实施例中,上行传输方式为第二传输方式,在第一时频资源中的全部资源能够使用时,终端设备通过第一时频资源向网络设备发送第一子数据,和/或,在第一时频资源中的至少部分资源不能够使用时,终端设备不通过第一时频资源向网络设备发送第二子数据。从而,终端设备可以通过第一时频资源在频域上占用的全部资源发送第一数据,且不通过第一时频资源在频域上占用的部分资源发送第一数据。

当信道检测带宽与数据传输带宽不一致时,例如,信道检测带宽为20MHz,数据传输带宽为40MHz,可能出现该40MHz中只有20MHz能够使用。在这种情况下,如果不允许使用该20MHz资源进行数据传输,那么会增加数据传输的时延;如果总是允许使用该20MHz资源进行数据传输,为了使数据传输在使用部分带宽资源时也有一定概率可以成功传输,需要使用比较保守的调度方式,从而会降低免授权频谱的频谱资源利用效率。因此,本申请实施例中提出两种数据传输方式,系统可以根据业务的时延要求、可靠性要求等灵活配置数据传输方式,从而更有效地利用频谱资源。
应理解,本申请实施例中的数据传输方法可用于上行物理信道或下行物理信道。为便于描述,以上行物理信道传输为例进行说明,对下行物理信道传输过程不再赘述。
图1是根据本申请实施例的数据传输的方法100的示意性流程图,如图1所示,该方法100可以包括如下内容:
S110,终端设备接收网络设备发送的调度信息,该调度信息用于调度该终端设备通过第一载波上的第一时频资源传输第一传输块,该第一传输块为一个物理信道承载的传输块。
S120,该终端设备对该第一传输块进行速率匹配,得到第一数据。
S130,该终端设备确定上行传输方式,该上行传输方式包括第一传输方式和第二传输方式,其中,该第一传输方式为通过该第一时频资源在频域上占用的全部或部分资源发送该第一数据,该第二传输方式为通过该第一时频资源在频域上占用的全部资源发送该第一数据,且不通过该第一时频资源在频域上占用的部分资源发送该第一数据。
S140,该终端设备对该第一载波进行信道检测,并根据检测结果和该上行传输方式通过该第一时频资源向该网络设备发送该第一数据。
可选地,该第一时频资源可以为免授权频谱上的资源。
可选地,该物理信道可以是PUCCH,也可以是PRACH,还可以是PUSCH。
可选地,该终端设备对该第一传输块进行速率匹配,得到第一数据,可以是该终端设备对该第一传输块进行编码、调制、速率匹配,进而得到和该第一时频资源的大小匹配的该第一数据。
可选地,该终端设备可以是在该第一传输块进行编码和调制的过程对该第一传输块进行速率匹配,进而得到该第一数据。
可选地,该终端设备可以根据“先听后说(Listen Before Talk,LBT)”原则,对该第一载波进行信道检测。即通信设备(终端设备)在免授权频谱的信道上进行信号发送前,需要先进行信道检测,只有当信道侦听结果为信道空闲时,该通信设备才能进行信号发送;如果通信设备在免授权频谱的信道上的信道检测结果为信道忙,该通信设备不能进行信号发送。
可选地,本申请实施例中,该调度信息为DCI、RRC信令和MAC CE信令中的一种。
需要说明的是,本申请实施例中,该调度信息还可以用于调度该终端设备通过该第一载波上的第一时频资源传输PUCCH,PRACH,PUSCH等上行信道中的信号。
可选地,本申请实施例中,该终端设备可以根据待传输的物理信道类型确定上行传输方式。例如,在该物理信道为PUSCH时(换句话说,该第一传输块为一个PUSCH信道承载的传输块时),该终端设备可以确定该上行传输方式为该第一传输方式。
又例如,在该物理信道为PUCCH或者PRACH时(换句话说,该第一传输块为一个PUCCH信 道承载的信息块,或者该第一传输块对应一个PRACH信道承载的前导序列时),该终端设备可以确定该上行传输方式为该第二传输方式。
当然,也可以是在该物理信道为PUSCH时,该终端设备确定该上行传输方式为该第二传输方式。或者,在该物理信道为PUCCH或者PRACH时,该终端设备确定该上行传输方式为该第一传输方式。
需要说明的是,在该物理信道为PRACH时,该调度信息可以用于调度该终端设备通过该第一载波上的第一时频资源传输第一序列(例如,前导序列),而非第一传输块。
可选地,本申请实施例中,该终端设备可以根据网络设备发送的指示信息确定上行传输方式。例如,终端设备接收网络设备发送的指示信息,该指示信息用于指示该第一传输方式或该第二传输方式;该终端设备根据该指示信息确定该上行传输方式。因此,终端设备可以根据网络设备发送的指示信息确定上行传输方式,从而,可以基于网络设备发送的指示信息确定传输上行数据时的上行传输方式。
可选地,该指示信息为物理层信令、RRC信令和MAC CE信令中的一种。
可选地,网络设备可以根据调度终端设备传输的第一传输块的优先级来确定终端设备的上行传输方式,例如,当终端设备请求传输的数据是高优先级的数据(例如URLLC数据)时,网络设备指示终端设备根据第一传输方式进行数据传输,否则,网络设备指示终端设备根据第二传输方式进行数据传输。
例如,第一传输块的优先级可以用单包优先级(ProSe Per-Packet Priority,PPPP)表示。
可选地,本申请实施例中,该上行传输方式为该第一传输方式,其中,该第一传输块中包括URLLC的数据和UCI中的至少一种。从而,可以确保URLLC的数据、UCI等的可靠传输。

具体地,该终端设备通过信道检测确定该第一子带能够使用,并通过该第一时频资源在该第一子带上占用的资源向该网络设备发送该第一子数据;和/或,
该终端设备通过信道检测确定该第二子带能够使用,并通过该第一时频资源在该第二子带上占用的资源向该网络设备发送该第二子数据。
需要说明的是,该第一时频资源占用该至少两个子带中的部分或者全部资源。
可选地,该第一子带和/或该第二子带的带宽可以是20MHz的整数倍,且该第一子带的带宽与该第二子带的带宽可以相同,也可以不同。例如,该第一子带的带宽为20MHz,该第二子带的带宽为40MHz。
可选地,该第一子带和/或该第二子带的带宽与信道检测带宽大小保持一致。
可选地,该第一时频资源在该第一子带上占用的资源大小与该第一时频资源在该第二子带上占用的资源大小可以相同,也可以不同。
需要说明的是,该第一子数据是该第一子带上映射的该第一数据中的数据,该第二子数据是该第二子带上映射的该第一数据中的数据。
例如,该终端设备对该第一子带与该第二子带进行信道检测,
若该第一子带与该第二子带都可用,该终端设备通过该第一时频资源在该第一子带上占用的资源向该网络设备发送该第一子数据,以及通过该第一时频资源在该第二子带上占用的资源向该网络设备发送该第二子数据;或者
若该第一子带可用,且该第二子带不可用,该终端设备通过该第一时频资源在该第一子带上占用的资源向该网络设备发送该第一子数据,以及放弃在该第一时频资源在该第二子带占用的资源上发送该第二子数据;或者
若该第一子带不可用,且该第二子带可用,该终端设备放弃在该第一时频资源在该第一子带占用的资源上发送该第一子数据,以及通过该第一时频资源在该第二子带上占用的资源向该网络设备发送该第二子数据;或者
若该第一子带与该第二子带都不可用,该终端设备放弃在该第一时频资源在该第一子带占用的资源上发送该第一子数据,以及放弃在该第一时频资源在该第二子带占用的资源上发送该第二子数据。
可选地,该第一子数据对应第一调制编码方案,该第二子数据对应第二调制编码方案。即第一子带上的数据对应的调制编码方案和第二子带上的数据对应的调制编码方案是独立确定的。
应理解,调制编码方案(Modulation and Coding Scheme,MCS)可以用于确定调制阶数(例如,正交相移键控(Quadrature Phase Shift Keying,QPSK)、16正交幅度调制(Quadrature Amplitude Modulation,16QAM)、64QAM、256QAM、1024QAM等)和/或码率。
可选地,该第一子数据与该第二子数据对应的调制阶数和/或码率是独立确定的。进一步可选地,第一调制编码方案是根据第一子带上的信噪比状况确定的,第二调制编码方案是根据第二子带上的信噪比状况确定的。该第一调制编码方案与该第二调制编码方案可能相同,也可能不同。因此,终端设备可以在至少两个子带上使用能够独立反映子带信噪比状况的调制编码方案,从而可以提高数据传输的效率。
可选地,本申请实施例中,该终端设备对该第一传输块进行速率匹配,得到第一数据,包括以下情况中的一种:
该终端设备对该第一传输块进行速率匹配得到该第一子数据,对该第一传输块进行速率匹配得到该第二子数据;

该第一传输块包括第一CBG和第二CBG,该终端设备对该第一CBG进行速率匹配得到该第一子数据,对该第二CBG进行速率匹配得到该第二子数据。
例如,在该终端设备对该第一传输块进行速率匹配得到该第一子数据,对该第一传输块进行速率匹配得到该第二子数据时,该第一子数据对应的速率匹配方式或冗余版本与该第二子数据对应的速率匹配方式或冗余版本可能不同,因此,该第一子数据与该第二子数据可能不同,但该第一子数据与该第二子数据对应相同的传输块。也就是说,终端设备在第一子带和第二子带上对第一传输块进行重复传输。
又例如,该第一传输块包括(Transport Block A,TB A)和TB B,该第一子数据为TB A进行速率匹配得到的数据,该第二子数据为TB B进行速率匹配得到的数据,从而,确保第一子带和第二子带上映射的数据可以独立译码和反馈。
应理解,该第一CBG包括整数个CBG,该第二CBG包括整数个CBG。
需要说明的是,若该第一传输块属于一个码字对应的一个传输块,例如,TB1,该第一CBG可以包括TB1中的整数个CBG,该第二CBG也可以包括TB1中的整数个CBG。
可选地,该第一CBG中的CBG与该第二CBG中的CBG没有交集。
若该第一传输块属于两个码字对应的两个传输块,例如,TB1和TB2,此时,该第一CBG与该第二CBG中所包括的CBG可以满足如下方式:
方式1,该第一CBG与该第二CBG可以包括TB1中的整数个CBG;
方式2,该第一CBG与该第二CBG可以包括TB2中的整数个CBG;
方式3,该第一CBG可以包括TB1中的整数个CBG,该第二CBG可以包括TB2中的整数个CBG;
方式4,该第一CBG可以包括TB2中的整数个CBG,该第二CBG可以包括TB1中的整数个CBG;
方式5,该第一CBG可以包括TB1中的m个CBG和TB2中的n个CBG,该第二CBG可以包括TB1中的x个CBG和TB2中的y个CBG,且m,n,x,y为正整数;
可选地,在上述各个方式中,该第一CBG中的CBG与该第二CBG中的CBG没有交集。
可选地,可以作为一个实施例,该上行传输方式为该第二传输方式。
具体地,该终端设备通过信道检测确定该第一时频资源中的全部资源能够使用,并通过该第一时频资源向该网络设备发送该第一数据;或,
该终端设备通过信道检测确定该第一时频资源中的至少部分资源不能够使用,该终端设备不通过该第一时频资源向该网络设备发送该第一数据。
因此,在本申请实施例中,上行传输方式为第二传输方式,在第一时频资源中的全部资源能够使用时,终端设备通过第一时频资源向网络设备发送第一子数据,和/或,在第一时频资源中的至少部分资源不能够使用时,终端设备不通过第一时频资源向网络设备发送第二子数据。从而,终端设备可以通过第一时频资源在频域上占用的全部资源发送第一数据,且不通过第一时频资源在频域上占用的部分资源发送第一数据。
可选地,本申请实施例中,该终端设备可以根据MCS索引对应的调制阶数对该第一传输块进行速率匹配,其中,当该上行传输方式为该第一传输方式时,该调制阶数是根据该MCS索引与第一MCS配置集合确定的,当该上行传输方式为该第二传输方式时,该调制阶数是根据该MCS索引与第二MCS配置集合确定的,该第一MCS配置集合与该第二MCS配置集合相异。
可选地,该MCS索引在该第一MCS配置集合中对应的调制阶数大于或等于该MCS索引在该第二MCS配置集合中对应的调制阶数;和/或,
该MCS索引在该第一MCS配置集合中对应的目标码率小于或等于该MCS索引在该第二MCS配置集合中对应的目标码率。
应理解,一个MCS配置集合中至少包括MCS索引和该MCS索引对应的调制阶数。可选地,该MCS集合中还包括MCS索引对应的目标码率。表1给出了第一MCS配置集合和第二MCS配置集合的一个示例。
可选地,对于同一个MCS索引,所述MCS索引在所述第一MCS配置集合中对应的调制阶数大于或等于所述MCS索引在所述第二MCS配置集合中对应的调制阶数。如表1所示,例如,假设MCS索引为10,MCS索引为10在第一MCS配置集合中对应的调制阶数为6,在第二MCS配置集合中对应的调制阶数为4。
可选地,对于同一个MCS索引,所述MCS索引在所述第一MCS配置集合中对应的目标码率小于或等于所述MCS索引在所述第二MCS配置集合中对应的目标码率。如表1所示,例如,假设MCS索引为10,MCS索引为10在第一MCS配置集合中对应的目标码率为226/1024=0.2207,在第二MCS配置集合中对应的目标码率为340/1024=0.3320。
