当上行控制信息例如,下行数据的反馈信息或信道状态信息等,需要背驮(Piggyback)映射到PUSCH进行承载时,可以采用背驮(Piggyback)传输方式。
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业务数据和控制信息。因此,本发明所涉及的类型可以包括但不限于eMBB业务类型、URLLC业务类型和mMTC业务类型中的至少一项业务类型,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之前,还可以进一步确定所述上行控制信息所属的类型。
所谓的类型,可以是指按照业务所划分的业务类型,例如,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),或者还可以指按照其他标准所划分的其他类型,本实施例对此不进行特别限定。
若所述上行控制信息所属的类型为第一类型,则可以在所述第一传输资源或所述第二传输资源上传输所述上行控制信息。
其中,第一类型可以是指低时延类型,或者还可以指其他类型,本实施例对此不进行特别限定。
在一个具体的实现过程中,具体可以根据传输参数,确定所述上行控制信息所属的类型。其中,所述传输参数可以包括但不限于如下参数中的至少一项:
业务类型指示;
传输时间间隔(Transmission Time Interval,TTI)长度,即下行数据的TTI;

周期,例如,SR的周期或CSI的周期等;以及
配置信息,例如,SR的配置信息,如SR配置序号或优先级,或者再例如,CSI的配置信息,如目标误块率(Block Error Rate,BLER)等。
可选地,在本实施例的一个可能的实现方式中,在102中,具体可以在所述第一传输资源的第一部分资源上传输所述上行控制信息。
在该实现方式中,所述上行控制信息,具体可以通过打孔(puncture)的方式映射到PUSCH上,或者还可以对PUSCH内所承载的上行数据进行速率匹配(Ratematching),以使得所述上行数据不映射到所述第一传输资源所占用的资源单元(Resource Element,RE)上。
在该实现方式中,所述第一部分资源可以仅用于传输上行控制信息,即在有上行控制信息时,用于传输上行控制信息,在没有上行控制信息时,也不用于传输上行数据,或者还可以不仅用于传输上行控制信息,即在有上行控制信息时,用于传输上行控制信息,在没有上行控制信息时,用于传输上行数据,本实施例对此不进行特别限定。
在该实现方式中,所述第一部分资源的周期与上行控制信息的周期,可以相同,或者还可以不相同,本实施例对此不进行特别限定。
在该实现方式中,在每个传输机会内,所配置的所述第一部分资源的数量可以相同,或者还可以不相同,例如,距离解调参考信号(Demodulation Reference Signal,DMRS)近的传输机会内所配置的所述第一部分资源的数量较少,本实施例对此不进行特别限定。
在一个具体的实现过程中,所述第一部分资源的最后一个符号不晚于所述第二传输资源的最后一个符号之后的N个符号,其中,N为大于或等于0的整数。优选地,N的取值可以为0。
在另一个具体的实现过程中,N的取值可以由网络设备配置。
具体来说,终端具体可以接收网络设备通过下行控制信息(Downlink Control Information,DCI)、高层信令或系统广播消息,所发送的N的取值。
例如,所述高层信令可以是无线资源控制(Radio Resource Control,RRC)消息,具体可以通过RRC消息中的信息元素(Information Element,IE)携带所述N的取值,所述RRC消息可以为现有技术中的RRC消息,例如,RRC连接重配置(RRC  CONNECTION RECONFIGURATION)消息等,本实施例对此不进行限定,通过对已有的RRC消息的IE进行扩展携带所述N的取值,或者所述RRC消息也可以为不同于现有技术中已有的RRC消息。
或者,再例如,所述高层信令可以是媒体访问控制(Media Access Control,MAC)控制元素(Control Element,CE)消息,具体还可以通过增加新的MAC CE消息携带所述N的取值。
或者,再例如,具体可以采用所述系统广播消息中现有的主信息块(Master Information Block,MIB)或(System Information Block,SIB)携带所述N的取值,或者还可以增加新的SIB携带所述N的取值。
可以理解的是,所述N的取值还可以由协议约定。
在另一个具体的实现过程中,所述第一部分资源,可以为所述第一传输资源中至少一个符号在频域上的部分不连续资源,以SR为例,如图1B所示。图1B中,所配置的传输SR的传输资源即SR资源的周期为2个符号,当终端有一个PUSCH发送时,同时有一个SR被触发,则可以在传输PUSCH的资源即PUSCH资源中2个符号在频域上的部分不连续资源上,传输SR。
在该实现过程中,SR可以采用特定序列,例如,原SR序列,序列有益于基站识别SR的发送,或者还可以采用特定数值,例如,1,或者还可以采用特定数值加扰,例如1加扰,且特定数值的扰码不同于上行数据的扰码,该限定有益于基站识别SR的发送,本实施例对此不进行特别限定。
在另一个具体的实现过程中,所述第一部分资源,可以为所述第一传输资源中至少一个符号在频域上的部分连续资源,以SR为例,如图1C所示。图1C中,所配置的传输SR的传输资源即SR资源的周期为2个符号,当终端有一个PUSCH发送时,同时有一个SR被触发,则可以在传输PUSCH的资源即PUSCH资源中2个符号在频域上的部分连续资源上,传输SR。
在该实现过程中,SR可以采用特定序列,例如,原SR序列,或者还可以采用特定数值,例如,1,或者还可以采用特定数值加扰,例如1加扰,且特定数值的扰码不同于上行数据的扰码,本实施例对此不进行特别限定。
优选地,对于连续的资源来说,可以优先传输特定序列,这样,能够保证SR的正交性。
在另一个具体的实现过程中,所述第一部分资源,可以为所述第一传输资源中至少一个符号在频域上的全部资源,以SR为例,如图1D所示。图1D中,所配置的传输SR的传输资源即SR资源的周期为2个符号,当终端有一个PUSCH发送时,同时有一个SR被触发,则可以在传输PUSCH的资源即PUSCH资源中2个符号在频域上的全部资源上,传输SR。
在该实现过程中,SR可以采用特定序列,例如,原SR序列,或者还可以采用特定数值,例如,1,或者还可以采用特定数值加扰,例如1加扰,且特定数值的扰码不同于上行数据的扰码,本实施例对此不进行特别限定。
在另一个具体的实现过程中,第一部分资源可以由网络设备配置。
具体来说,终端具体可以接收网络设备通过下行控制信息(Downlink Control Information,DCI)、高层信令或系统广播消息,所发送的第一部分资源。
例如,所述高层信令可以是无线资源控制(Radio Resource Control,RRC)消息,具体可以通过RRC消息中的信息元素(Information Element,IE)携带所述第一部分资源,所述RRC消息可以为现有技术中的RRC消息,例如,RRC连接重配置(RRC CONNECTION RECONFIGURATION)消息等,本实施例对此不进行限定,通过对已有的RRC消息的IE进行扩展携带所述第一部分资源,或者所述RRC消息也可以为不同于现有技术中已有的RRC消息。
或者,再例如,所述高层信令可以是媒体访问控制(Media Access Control,MAC)控制元素(Control Element,CE)消息,具体还可以通过增加新的MAC CE消息携带所述第一部分资源。
或者,再例如,具体可以采用所述系统广播消息中现有的主信息块(Master Information Block,MIB)或(System Information Block,SIB)携带所述第一部分资源,或者还可以增加新的SIB携带所述第一部分资源。
可以理解的是,所述第一部分资源还可以由协议约定。
可选地,在本实施例的一个可能的实现方式中,在102中,具体可以在所述第二传输资源上传输所述上行控制信息,在所述第一传输资源上传输所述上行数据。
在一个具体的实现过程中,如果终端的功率不受限,上行控制信息与上行数据则可以分别采用既定方式进行传输,以SR为例,如图1E所示。图1E中,所配置的传输SR的传输资源即SR资源的周期为2个符号,当终端有一个PUSCH发送时,同时有一个SR被触发,则可以在传输SR的资源即SR资源上,传输SR,可以在传输PUSCH的资源即PUSCH资源上,传输上行数据。
在另一个具体的实现过程中,如果终端的功率受限,上行控制信息与上行数据则可以采用功率调整(Power Scaling)方式进行调整传输。
例如,可以在SR资源上,采用满功率传输SR,而在PUSCH资源中上,采用降低的功率传输PUSCH资源。具体来说,具体可以当PUSCH采用比正交相移键控(Quadrature Phase Shift Key,QPSK)更高级调制方式,采用这种方式。
或者,再例如,可以在SR资源上,采用满功率传输SR,而在PUSCH资源中与SR资源在时域上重叠的资源上,采用降低的功率传输PUSCH资源,在PUSCH资源中与SR资源在时域上不重叠的资源上,采用满功率传输PUSCH资源。具体来说,具体可以当PUSCH采用QPSK及更低级调制方式,采用这种方式。
或者,再例如,可以等比例进行功率减少,那么,则可以在SR资源上,采用第一功率传输SR,其中,第一功率为传输SR的满功率的k倍,k为大于0且小于1的数值,而在PUSCH资源中,采用第二功率,传输PUSCH资源,其中,第二功率为传输PUSCH的满功率的k倍。
或者,再例如,可以按照物理资源块(Physical Resource Block,PRB)数目比例进行功率减少,那么,则可以在SR资源上,采用第三功率传输SR,其中,第三功率为传输SR的满功率的m倍,m为大于0且小于1的数值,而在PUSCH资源中,采用第四功率传输PUSCH资源,其中,第四功率为传输SR的满功率的n倍,n为大于0且小于1的数值。m和n的取值,可以根据SR和上行数据所占用的PRB数量获得。
可选地,在本实施例的一个可能的实现方式中,在102中,具体可以在所述第二传输资源上传输所述上行控制信息,在所述第一传输资源的第二部分资源上暂停传输所述上行数据。
具体来说,所述第二部分资源,可以包括但不限于所述第一传输资源中与所述第二传输资源在时域上重叠的全部资源,本实施例对此不进行特别限定,以SR为例,如图1F所示。图1F中,所配置的传输SR的传输资源即SR资源的周期为2个符号,当终端有一个PUSCH发送时,同时有一个SR被触发,则可以仅在传输SR的资源即SR资源上,传输SR,在传输PUSCH的资源即PUSCH资源中与SR资源在时域上重叠的全部资源上,暂停传输上行数据,如图1F中的“X”所示,在传输PUSCH的资源即PUSCH资源中与SR资源在时域上不重叠的全部资源上,继续传输上行数据。
在一个具体的实现过程中,所述上行控制信息的开始传输时间早于所述上行数据的开始传输时间,如图1G。
否则,若所述上行控制信息的开始传输时间晚于所述上行数据的开始传输时间,则可以采用现有技术中的技术方案,仅在传输PUSCH的资源即PUSCH资源上,传输上 行数据,该PUSCH资源上还可以进一步传输缓存状态报告(Buffer Status Report,BSR)。
可选地,在本实施例的一个可能的实现方式中,在102中,具体可以在所述第二传输资源上传输所述上行控制信息,在所述第一传输资源上终止传输所述上行数据,以SR为例,如图1H所示。图1H中,所配置的传输SR的传输资源即SR资源的周期为2个符号,当终端有一个PUSCH发送时,同时有一个SR被触发,则可以仅在传输SR的资源即SR资源上,传输SR,在传输PUSCH的资源即PUSCH资源上,终止传输上行数据。
该实现方式中,若所述上行控制信息的开始传输时间晚于所述上行数据的开始传输时间,则可以从所述第一传输资源中与所述第二传输资源在时域上重叠的资源开始,终止传输上行数据,或者若所述上行控制信息的开始传输时间早于所述上行数据的开始传输时间,则还可以始终都不在第一传输资源上,传输上行数据,本实施例对此不进行特别限定。
在一个具体的实现过程中,所述上行控制信息的开始传输时间早于所述上行数据的开始传输时间,如图I和图J所示。
否则,若所述上行控制信息的开始传输时间晚于所述上行数据的开始传输时间,则可以采用现有技术中的技术方案,仅在传输PUSCH的资源即PUSCH资源上,传输上行数据,该PUSCH资源上还可以进一步传输缓存状态报告(Buffer Status Report,BSR)。
采用本发明所提供的技术方案,能够有效保证上行控制信息的即时传输,从而减少了上行业务的时延。同时,对于低时延要求的下行数据的反馈信息和信道状态信息,尽量避免背驮(Piggyback)映射到PUSCH进行承载。
本实施例中,通过确定待传输的上行数据对应的第一传输资源与待传输的上行控制信息对应的第二传输资源在时域上存在重叠,使得能够在所述第一传输资源或所述第二传输资源上传输所述上行控制信息,从而实现了在终端发生传输上行控制信息的传输资源与传输上行数据的传输资源在时域上冲突时上行控制信息的即时传输。
