102、在所述至少两个传输资源中的至少一个传输资源上传输数据。
需要说明的是,101~102的执行主体的可以为终端,或者还可以为网 络设备,本实施例对此不进行特别限定。
本发明中,所传输的数据,是指终端与网络设备之间需要传输的信息,可以由物理上行信道进行承载,其中,所述物理上行信道可以包括但不限于物理上行共享信道(Physical Uplink Shared Channel,PUSCH)和物理上行控制信道(Physical Uplink Control Channel,PUCCH)中的至少一个。
本发明所提供的技术方案,可以应用在新无线(New Radio,NR)系统例如5G应用中,该NR系统可以具有三大业务场景,一种是增强型移动宽带(Enhance Mobile Broadband,eMBB)业务,一种是高可靠低时延(Ultra Reliable and Low Latency Communication,URLLC)业务,一种是海量机器类通信(massive Machine Type of Communication,mMTC)。终端可以根据业务需求,在所配置的传输资源上传输这些业务的数据。因此,本发明所涉及的所传输的数据可以包括但不限于eMBB数据、URLLC数据和mMTC数据中的至少两项,本实施例对此不进行特别限定。
可选地,在本实施例的一个可能的实现方式中,在101中,所传输的调度信息,可以为动态调度信息,或者还可以为半静态调度信息,本实施例对此不进行特别限定。
可选地,在本实施例的一个可能的实现方式中,在102中,具体可以在所述至少两个调度信息对应的第一传输资源上传输第一数据。
本实现方式中,所传输的数据除了第一数据之外,还可以进一步包括第二数据。其中,所述第一数据的业务优先级大于或等于所述第二数据的业务优先级。
那么,在新无线(New Radio,NR)系统例如5G应用中,所述URLLC数据的优先级大于所述eMBB数据的优先级;所述eMBB数据的优先级大 于所述mMTC数据的优先级。
在一个具体的实现过程中,还可以进一步在所述至少两个调度信息对应的第二传输资源的第一部分资源上不传输任何数据,在所述第二传输资源的第二部分资源上传输第二数据。
其中,所述第一部分资源,可以包括但不限于所述第二传输资源中与所述第一传输资源在时域上重叠的全部资源或部分资源;所述第二部分资源,可以包括但不限于包括所述第二传输资源中与所述第一传输资源在时域上不重叠的全部资源或部分资源。
例如,若所述第二部分资源的全部资源有相应的解调导频,在所述第二部分资源的全部资源上传输所述第二数据。
这样,能够使得解调导频能够解调数据的情况下,尽可能地利用可用的传输资源进行数据传输,从而有效提高了系统效率。
或者,再例如,若所述第二部分资源的部分资源有相应的解调导频,在所述第二部分资源的部分资源上传输所述第二数据。
这样,能够使得解调导频能够解调数据的情况下,尽可能地利用可用的传输资源进行数据传输,从而有效提高了系统效率。
或者,再例如,若所述第二部分资源的部分资源没有相应的解调导频,在所述第二部分资源的部分资源上不传输任何数据。
这样,能够避免进行毫无意义的传输,从而有效降低了系统干扰。
或者,再例如,若所述第二部分资源的全部资源没有相应的解调导频,在所述第二部分资源的全部资源上不传输任何数据。
这样,能够避免进行毫无意义的传输,从而有效降低了系统干扰。
在这几个例子中,具体可以判断第二传输资源中是否包含能够解调第 二部分资源的全部资源或者部分资源上所传输数据的解调导频,若第二传输资源中包含能够解调第二部分资源的全部资源或者部分资源上所传输数据的解调导频,即所述第二部分资源的全部资源或者部分资源有相应的解调导频;若第二传输资源中不包含能够解调第二部分资源的全部资源或者部分资源上所传输数据的解调导频,即所述第二部分资源的全部资源或者部分资源没有相应的解调导频。
为使得本发明实施例提供的方法更加清楚,下面将以URLLC数据和eMBB数据的传输资源部分重叠作为举例。
在确定调度信息所对应的两个数据即URLLC数据和eMBB数据的传输资源在时域上存在部分重叠之后,由于所述URLLC数据的优先级大于所述eMBB数据的优先级,那么则可以在所述第二传输资源与第一传输资源在时域上重叠的第一部分资源上不传输任何数据,在所述第二传输资源与第一传输资源在时域上不重叠的的第二部分资源上传输eMBB数据。
如何在所述第二传输资源的第二部分资源上传输eMBB数据,可以有多种方式,下面将给出几种例子。
如图1B所示,假设第二数据为eMBB数据,eMBB数据中包含1列解调导频(如图中阴影部分所示)。该1列导频在第二部分资源上,说明第二部分资源的全部资源有相应的解调导频,因此,则可以在重叠的第一部分资源上不传输任何数据(如图中X所示),在不重叠的第二部分资源的全部资源上传输eMBB数据。
如图1C所示,假设第二数据为eMBB数据,eMBB数据中包含4列解调导频(如图中阴影部分所示),其中,第1列解调导频和第2列解调导频采用时域正交覆盖编码(Orthogonal Cover Code,OCC)复用,第3 列解调导频和第4列解调导频采用时域OCC复用。第1列导频和第2列导频,以及第3列解调导频和第4列解调导频均在第二部分资源上,说明第二部分资源的全部资源有相应的解调导频,因此,则可以在重叠的第一部分资源上不传输任何数据(如图中X所示),在不重叠的第二部分资源的全部资源上传输eMBB数据。
如图1D所示,假设第二数据为eMBB数据,eMBB数据中包含4列解调导频(如图中阴影部分所示),其中,第1列解调导频和第2列解调导频采用时域OCC复用,第3列解调导频和第4列解调导频采用时域OCC复用。第1列导频和第2列导频在第二部分资源的第一个部分上,说明第二部分资源中包含第1列解调导频和第2列解调导频所对应的eMBB数据的解调导频即第二部分资源的这部分资源有相应的解调导频,因此,在第二部分资源的这部分资源上传输eMBB数据。第3列解调导频和第4列解调导频在第一部分资源上,那么,由于在第一部分资源上不传输任何数据,第3列解调导频和第4列解调导频需要被打掉,说明第二部分资源中不包含第3列解调导频和第4列解调导频所对应的eMBB数据的解调导频即第二部分资源的这部分资源没有相应的解调导频,则在第一部分资源、以及第二部分资源的这部分资源上不传输任何数据(如图中X所示)。
如图1E所示,假设第二数据为eMBB数据,eMBB数据中包含4列解调导频(如图中阴影部分所示),其中,第1列解调导频和第2列解调导频没有采用时域OCC复用,第3列解调导频和第4列解调导频也没有采用时域OCC复用。第1列导频、第2列导频和第3列解调导频在第二部分资源的第一个部分上,说明第二部分资源中包含第1列解调导频和第2列解调导频所对应的eMBB数据的解调导频即第二部分资源的这部分资源有 相应的解调导频,因此,在第二部分资源的这部分资源上传输eMBB数据。第4列解调导频在第一部分资源上,由于在第一部分资源上不传输任何数据,第4列解调导频需要被打掉,但是,由于第3列解调导频解调数据并不依赖于第4列解调导频,说明第二部分资源中仍然包含第3列解调导频和第4列解调导频所对应的eMBB数据的解调导频即即第二部分资源的这部分资源有相应的解调导频,因此,在第二部分资源的这部分资源上也可以传输eMBB数据,在第一部分资源上不传输任何数据(如图中X所示)。
如图1F所示,假设第二数据为eMBB数据,eMBB数据中包含4列解调导频(如图中阴影部分所示),其中,第1列解调导频和第2列解调导频采用时域OCC复用,第3列解调导频和第4列解调导频采用时域OCC复用。第1列导频、第2列导频和第3列解调导频在第二部分资源的第一个部分上,说明第二部分资源中包含第1列解调导频和第2列解调导频所对应的eMBB数据的解调导频即第二部分资源的这部分资源有相应的解调导频,因此,在第二部分资源的这部分资源上传输eMBB数据。第4列解调导频在第一部分资源上,由于在第一部分资源上不传输任何数据,第4列解调导频需要被打掉,但是,由于第3列解调导频解调数据依赖于第4列解调导频,说明第二部分资源中不包含第3列解调导频和第4列解调导频所对应的eMBB数据的解调导频即第二部分资源的这部分资源没有相应的解调导频,则在第一部分资源、以及第二部分资源的这部分资源上不传输任何数据(如图中X所示)。
在另一个具体的实现过程中,还可以进一步在所述至少两个调度信息对应的第二传输资源上不传输任何数据。
在另一个具体的实现过程中,还可以进一步若第二数据采用QPSK调 制或BPSK调制,在所述至少两个调度信息对应的第二传输资源的第一部分资源上采用第一功率传输所述第二数据,在所述第二传输资源的第二部分资源上采用第二功率传输所述第二数据。其中,第二功率可以为对应调度信息所指示的功率,第一功率则可以为小于对应调度信息所指示的功率。
其中,所述第一部分资源,可以包括但不限于所述第二传输资源中与所述第一传输资源在时域上重叠的全部资源或部分资源;所述第二部分资源,可以包括但不限于包括所述第二传输资源中与所述第一传输资源在时域上不重叠的全部资源或部分资源。
这样,通过在所述第二传输资源中与所述第一传输资源在时域上重叠的全部资源或部分资源即第一部分资源上降低功率传输第二数据,能够在保证能够解调正确的条件下,尽可能地利用可用的传输资源进行数据传输,从而有效提高了系统效率。
在另一个具体的实现过程中,还可以进一步若第二数据采用QAM调制,在所述至少两个调度信息对应的第二传输资源上采用第一功率传输所述第二数据;或者在所述至少两个调度信息对应的第二传输资源上不传输任何数据。其中,第一功率可以为小于对应调度信息所指示的功率。
这样,能够在保证能够解调正确的条件下,尽可能地利用可用的传输资源进行数据传输,从而有效提高了系统效率。
本实施例中,通过传输至少两个调度信息,所述至少两个调度信息对应的至少两个传输资源在时域上存在部分重叠,使得能够在所述至少两个传输资源中的至少一个传输资源上传输数据,从而实现了在终端发生传输两个或者两个以上数据的部分传输资源在时域上冲突时的数据传输。
