Abstract
一种上行控制信息发送、接收方法及设备,用于提高5G***里的子帧对于PUCCH的覆盖。其中,一种上行控制信息发送方法包括:用户设备获取上行控制信息;所述用户设备将所述上行控制信息映射到至少两个传输时间单元中发送给网络设备。
Description
本申请要求在2016年9月30日提交中国专利局、申请号为201610874921.X、发明名称为“一种上行控制信息发送、接收方法及设备”的中国专利申请的优先权,其全部内容通过引用结合在本申请中。
本发明涉及通信技术领域,特别涉及一种上行控制信息发送、接收方法及设备。
在未来的第五代移动通信***(5G)中,为了能够快速传输和快速控制信息反馈,可能会引入新的子帧类型,即自包含子帧(Self-contained Subframe),该自包含子帧可以包括第一类型的子帧和/或第二类型的子帧,下文中将第一类型的子帧简称为S1子帧,将第二类型的子帧简称为S2子帧。S1子帧和S2子帧中均包括用于下行传输的符号、保护间隔(Guard Period,GP)和用于上行传输的符号。
其中,S1子帧中用于下行传输的符号主要用于传输下行控制信息和下行数据,用于上行传输的符号主要用于传输上行控制信息(Uplink Control Information,UCI)和探测参考信号(Sounding Reference Signal,SRS)。目前,对于S1子帧中包括的用于下行传输的符号、GP所占用的符号和用于上行传输的符号的数量还没有确定,但基本确定的是用于上行传输的符号的数量不会太多,例如,若S1子帧共包括14个符号,那么用于上行传输的符号可能为1个或2个等。
现有的长期演进(Long Term Evolution,LTE)***中,物理上行控制信道(Physical Uplink Control Channel,PUCCH)在时域上需占用14个符号,也就是一个子帧里有14个符号可以用于传输UCI,而根据以上介绍可知,S1子帧中用于传输UCI的符号数量较少。因此相比LTE,S1子帧中对于PUCCH的覆盖较差,很可能导致有些上行控制信息无法传输。
发明内容
本发明实施例提供一种上行控制信息发送、接收方法及设备,用于提高5G***里的子帧对于PUCCH的覆盖。
第一方面,提供一种上行控制信息发送方法,该方法由用户设备执行。该方法包括:用户设备获取上行控制信息,用户设备将上行控制信息映射到至少两个传输时间单元中发送给网络设备。
本发明实施例中,用户设备可以将上行控制信息映射到至少两个传输时间单元中发送,这样上行控制信息可以占用较多的符号,提高了对于PUCCH的覆盖,特别是当需要传输的上行控制信息较多时,可以有效避免因为没有资源而导致上行控制信息无法传输的情况。
结合第一方面,在第一方面的第一种可能的实现方式中,用户设备将上行控制信息映射到至少两个传输时间单元中发送给网络设备,可以通过以下方式实现:用户设备将上行控制信息的部分信息映射到第一传输时间单元的最后M个符号上,以及将上行控制信息中剩余的信息映射到第二传输时间单元的前N个符号上,以将上行控制信息发送给网络设备。
其中,第一传输时间单元和第二传输时间单元为连续的传输时间单元,M、N均为正整数。
用户设备将上行控制信息分别映射到第一传输时间单元和第二传输时间单元中,这样上行控制信息可以占用两个传输时间单元中的上行符号,能够占用的符号数较多,可以使得上行控制信息得到充分传输,尽量避免出现因上行传输资源有限导致上行控制信息无法传输的情况。且第一传输时间单元和第二传输时间单元为连续的传输时间单元,用户设备将上行控制信息的部分信息映射到第一传输时间单元的最后M个符号上,以及将上行控制信息中剩余的信息映射到第二传输时间单元的前N个符号上,尽量保证上行控制信息能够连续传输,提高数据传输质量。
结合第一方面的第一种可能的实现方式,在第一方面的第二种可能的实现方式中,既然用户设备要在第一传输时间单元中发送上行控制信息的部分信息,那么就需要知道上行控制信息的部分信息在第一传输时间单元中所占据的频域位置。用户设备确定上行控制信息的部分信息在第一传输时间单元中的频域位置,包括但不限于以下两种方式:用户设备还接收网络设备发送的控制信令,根据控制信令确定上行控制信息的部分信息在第一传输时间单元中的频域位置;或,用户设备确定接收的下行数据对应的下行控制信息,根据下行控制信息的第一个控制信道单元的编号计算得到部分信息在第一传输时间单元中的频域位置。
即,上行控制信息的部分信息在第一传输时间单元中的频域位置可以由网络设备通知用户设备,或者也可以由用户设备自行计算,方式较为灵活,可以根据实际情况来选择不同的方式确定上行控制信息的部分信息在第一传输时间单元中的频域位置。
结合第一方面的第一种可能的实现方式或第二种可能的实现方式,在第一方面的第三种可能的实现方式中,既然用户设备要在第二传输时间单元中发送上行控制信息中剩余的信息,那么就需要知道上行控制信息中剩余的信息在第二传输时间单元中所占据的频域位置。其中,上行控制信息在第二传输时间单元中占据的频域位置与上行控制信息在所述第一传输时间单元中占据的频域位置相同;或,上行控制信息在第二传输时间单元中占据的频域位置与上行控制信息在第一传输时间单元中占据的频域位置之间相差第一偏移量。
本发明实施例中,上行控制信息在第二传输时间单元中占据的频域位置可以有不同的情况,可根据***情况进行设置。其中,上行控制信息在第二传输时间单元中占据的频域位置可以由网络设备通知用户设备,例如网络设备在控制信令中一并通知用户设备,或者也可以由用户设备自行计算,方式较为灵活。那么,如果上行控制信息在第二传输时间单元中占据的频域位置与上行控制信息在第一传输时间单元中占据的频域位置之间相差第一偏移量,则第一偏移量可以由网络设备发送给用户设备,或者也可以通过协议或标准预定义,本发明实施例不作限制。
结合第一方面的第一种可能的实现方式或第二种可能的实现方式,在第一方面的第四种可能的实现方式中,上行控制信息在第二传输时间单元中占据的频域位置为连续的P个子载波。其中,P个子载波中包括在第二传输时间单元分配给用户设备的上行时频资源中编号最小的子载波,或P个子载波中包括在第二传输时间单元分配给用户设备的上行时频资源中编号最大的子载波,P为正整数。
也就是说,上行控制信息中剩余的信息在第二传输时间单元中可以占据连续的P个子载波,以实现连续发送。另外,上行控制信息中剩余的信息在第二传输时间单元中尽量分布在频域边缘位置,尽量保证第二传输时间单元的频域中心位置是连续的。在这种实施方
式中,不限制P个子载波上是否承载了上行数据,也就是说,可以将上行控制信息中剩余的信息与第二传输时间单元中应该传输的上行数据一并发送,提高资源复用率。
结合第一方面,在第一方面的第五种可能的实现方式中,用户设备将上行控制信息映射到至少两个传输时间单元中发送给网络设备,可以通过以下方式实现:用户设备将上行控制信息重复映射到至少两个传输时间单元中,以将至少两个上行控制信息发送给网络设备。其中,至少两个传输时间单元为连续的传输时间单元,或至少两个传输时间单元为不连续的传输时间单元。
在这种实现方式中,用户设备相当于向网络设备重复发送上行控制信息,网络设备应该收到的是至少两个上行控制信息。特别是对于覆盖比较差或网络质量比较差的用户设备,通过这种重复发送的方式可以尽量保证网络设备能够成功接收上行控制信息,提高上行控制信息发送的成功率。
结合第一方面或第一方面的第一种可能的实现方式至第五种可能的实现方式中的任一种可能的实现方式,在第一方面的第六种可能的实现方式中,传输时间单元包括一个或多个子帧,或传输时间单元包括一个或多个时隙,或传输时间单元包括一个或多个符号。
本发明实施例中,传输时间单元可以是传统意义上的子帧,或者也可能是在5G***或下一代通信***里将会使用的传输间隔,或者也可能有其他的定义。
结合第一方面或第一方面的第一种可能的实现方式至第六种可能的实现方式中的任一种可能的实现方式,在第一方面的第七种可能的实现方式中,上行控制信息包括:用于混合自动重传请求的确认应答/否定应答,和/或,信道状态信息。
本发明实施例中的上行控制信息可以包括传统意义的上行控制信息,例如HARQ技术中的ACK/NACK,CSI等,对于上行控制信息具体包括的内容本发明实施例不作限制,可参考现有技术中上行控制信息所包括的内容,以及还包括今后的通信***中可能的上行方向的控制信息。
第二方面,提供一种上行控制信息接收方法,该方法由网络设备执行。该方法包括:网络设备向用户设备发送控制信令,该控制信令用于指示用户设备将上行控制信息映射到至少两个传输时间单元中发送给网络设备。网络设备在至少两个传输时间单元中接收用户设备发送的上行控制信息。
本发明实施例中,网络设备可以指示用户设备将上行控制信息映射到至少两个传输时间单元中发送,这样上行控制信息可以占用较多的符号,提高了对于PUCCH的覆盖,特别是当需要传输的上行控制信息较多时,可以有效避免因为没有资源而导致上行控制信息无法传输的情况。
结合第二方面,在第二方面的第一种可能的实现方式中,控制信令还指示用户设备将上行控制信息的部分信息映射到第一传输时间单元的最后M个符号上,以及将上行控制信息中剩余的信息映射到第二传输时间单元的前N个符号上。其中,第一传输时间单元和所述第二传输时间单元为连续的传输时间单元,M、N均为正整数。在这种情况下,网络设备在至少两个传输时间单元中接收用户设备发送的上行控制信息,通过以下方式实现:网络设备在第一传输时间单元的最后M个符号上接收上行控制信息的部分信息,以及在第二传输时间的前N个符号上接收上行控制信息中剩余的信息。
网络设备指示用户设备将上行控制信息放到两个传输时间单元里发送,使得上行控制信息可以占用两个传输时间单元中的上行符号,上行控制信息可以占用的上行符号数较多,
提高了上行资源的覆盖。另外用户设备通过两个连续的传输时间单元实现上行控制信息的连续映射,网络设备也可以实现连续接收,提高数据发送质量以及数据接收质量。
结合第二方面的第一种可能的实现方式,在第二方面的第二种可能的实现方式中,控制信令还指示上行控制信息的部分信息在第一传输时间单元中的频域位置;或,控制信令还指示用户设备,根据在接收的下行数据对应的下行控制信息的第一个控制信道单元的编号计算上行控制信息的部分信息在第一传输时间单元中的频域位置。
网络设备通过控制信令可以直接将上行控制信息的部分信息在第一传输时间单元中的频域位置告知用户设备,用户设备接收控制信令后就可以直接获得上行控制信息的部分信息在第一传输时间单元中的频域位置,方式较为简单。或者网络设备可以通知用户设备自行计算上行控制信息的部分信息在第一传输时间单元中的频域位置,那么用户设备通过计算就可以获得上行控制信息的部分信息在第一传输时间单元中的频域位置,减少了控制信令的数据量,节省传输资源。当然这里介绍的是上行控制信息的部分信息在第一传输时间单元中的频域位置由网络设备通知用户设备的情况,在其他实现方式中,用户设备也可以根据协议或标准的预定义获得上行控制信息的部分信息在第一传输时间单元中的频域位置,本发明实施例不作限制。
结合第二方面的第一种可能的实现方式或第二种可能的实现方式,在第二方面的第三种可能的实现方式中,控制信令还指示上行控制信息在第二传输时间单元中占据的频域位置与上行控制信息在第一传输时间单元中占据的频域位置相同;或,控制信令还指示上行控制信息在第二传输时间单元中占据的频域位置与上行控制信息在第一传输时间单元中占据的频域位置之间相差第一偏移量。
网络设备除了可以指示上行控制信息的部分信息在第一传输时间单元中的频域位置外,还可以向用户设备指示上行控制信息中剩余的信息在第二传输时间单元中的频域位置。其中,上行控制信息的部分信息在第一传输时间单元中的频域位置与上行控制信息中剩余的信息在第二传输时间单元中的频域位置可以相同,那么网络设备直接告知用户设备即可,或者,上行控制信息的部分信息在第一传输时间单元中的频域位置与上行控制信息中剩余的信息在第二传输时间单元中的频域位置可以相差第一偏移量,那么用户设备只要获得了上行控制信息的部分信息在第一传输时间单元中的频域位置以及第一偏移量,就可以得到上行控制信息中剩余的信息在第二传输时间单元中的频域位置。其中,第一偏移量可以由网络设备通过控制信令一并发送给用户设备,或者也可以通过协议或标准预定义。另外,在其他的实现方式中,用户设备也可以通过协议或标准的预定义确定上行控制信息中剩余的信息在第二传输时间单元中的频域位置究竟与上行控制信息的部分信息在第一传输时间单元中的频域位置相同还是相差第一偏移量,以及第一偏移量可以由网络设备发送给用户设备,或者也可以由用户设备根据协议或标准的预定义获得。也就是说,用户设备获得上行控制信息中剩余的信息在第二传输时间单元中的频域位置的方式较多,可以根据情况选择不同的方式。
结合第二方面的第一种可能的实现方式或第二种可能的实现方式,在第二方面的第四种可能的实现方式中,控制信令还指示上行控制信息在第二传输时间单元中占据的频域位置为连续的P个子载波。其中,P个子载波中包括在第二传输时间单元分配给用户设备的上行时频资源中编号最小的子载波,或P个子载波中包括在第二传输时间单元分配给用户设备的上行时频资源中编号最大的子载波,P为正整数。
也就是尽量使得上行控制信息中剩余的信息在第二传输时间单元中占据连续的频域位置,得以进行连续映射,提高发送质量。以及,上行控制信息中剩余的信息在第二传输时间单元中可以尽量占据频域边缘的位置,使得第二传输时间单元的中心频域位置尽量连续。
结合第二方面,在第二方面的第五种可能的实现方式中,网络设备在至少两个传输时间单元中接收用户设备发送的所述上行控制信息,包括:网络设备在至少两个传输时间单元中接收至少两个上行控制信息。其中,至少两个传输时间单元为连续的传输时间单元,或至少两个传输时间单元为不连续的传输时间单元。
在这种实现方式下,用户设备是重复向网络设备发送上行控制信息,那么网络设备可以接收至少两个上行控制信息,提高了上行控制信息的发送成功率和接收成功率。特别是对于覆盖比较差的用户设备或网络质量比较差的用户设备,通过这种重复发送的方式,可以使得网络设备尽量能够接收上行控制信息,避免上行控制信息丢失。
结合第二方面或第二方面的第一种可能的实现方式至第五种可能的实现方式中的任一种可能的实现方式,在第二方面的第六种可能的实现方式中,传输时间单元包括一个或多个子帧,或传输时间单元包括一个或多个时隙,或传输时间单元包括一个或多个符号。
结合第二方面或第二方面的第一种可能的实现方式至第六种可能的实现方式中的任一种可能的实现方式,在第二方面的第七种可能的实现方式中,上行控制信息包括:用于混合自动重传请求的确认应答/否定应答,和/或,信道状态信息。
第三方面,提供一种上行控制信息发送方法,该方法由用户设备执行。该方法包括:用户设备获取上行控制信息。用户设备在第一传输时间单元向网络设备发送上行控制信息。其中,用户设备将上行控制信息映射到第一传输时间单元包括的符号集合中的全部符号上或部分符号上。符号集合包括第一传输时间单元的最后M个符号,M为正整数。
在传输时间单元中,可能包括多个用于传输上行控制信息的符号,符号集合中例如包括用于第一传输时间单元里用于传输上行控制信息的符号。那么用户设备在发送上行控制信息时,可以将上行控制信息映射到符号集合里的全部符号上发送,使得上行控制信息有较为充足的上行传输资源可用,或者也可以将上行控制信息映射到符号集合里的部分符号上发送,方式较为灵活。
结合第三方面,在第三方面的第一种可能的实现方式中,若用户设备将上行控制信息映射到第一传输时间单元包括的符号集合中的部分符号上,则用户设备在符号集合中未映射上行控制信息的符号上还可以向网络设备发送参考信号。
也就是说,用户设备映射上行控制信息只占用了符号集合中的部分符号,为了提高传输资源的利用率,可以在符号集合中未映射上行控制信息的符号上映射网络设备其他信息,例如参考信号,这样可以通过有限的传输资源向网络设备发送尽可能多的信息。
第四方面,提供一种上行控制信息接收方法,该方法由网络设备执行。该方法包括:网络设备向用户设备发送控制信令,该控制信令用于指示用户设备将上行控制信息映射到第一传输时间单元包括的符号集合中的全部符号上或部分符号上发送给网络设备。其中,符号集合包括第一传输时间单元的最后M个符号,M为正整数。那么,若控制信令用于指示用户设备将上行控制信息映射到符号集合中的全部符号上发送给网络设备,则网络设备在符号集合中的全部符号上接收上行控制信息;或,若控制信令用于指示用户设备将上行控制信息映射到符号集合中的部分符号上发送给网络设备,则网络设备在符号集合中的
部分符号上接收上行控制信息。
在传输时间单元中,可能包括多个用于传输上行控制信息的符号,符号集合中例如包括用于第一传输时间单元里用于传输上行控制信息的符号。那么网络设备可以指示用户设备将上行控制信息映射到符号集合里的全部符号上发送,使得上行控制信息有较为充足的上行传输资源可用,或者也可以将上行控制信息映射到符号集合里的部分符号上发送,网络设备可以根据网络情况、用户设备的类型等不同因素来指示用户设备究竟将上行控制信息映射到哪些符号上,较为灵活。
结合第四方面,在第四方面的第一种可能的实现方式中,若控制信令用于指示用户设备将上行控制信息映射到符号集合中的部分符号上发送给网络设备,则控制信令还指示用户设备在符号集合中未映射上行控制信息的符号上向网络设备发送参考信号。在这种情况下,网络设备还可以在符号集合中未映射上行控制信息的符号上接收参考信号。
若用户设备映射上行控制信息只占用了符号集合中的部分符号,为了提高传输资源的利用率,则网络设备可以指示用户设备在符号集合中未映射上行控制信息的符号上映射其他信息,例如参考信号,这样网络设备可以通过有限的传输资源接收尽可能多的信息。
第五方面,提供一种下行信息发送方法,该方法由网络设备执行。该方法包括:网络设备获取下行信息。网络设备在第一传输时间单元向用户设备发送该下行信息。其中,网络设备为发送下行信息在第一传输时间单元中占用的符号不包括第一传输时间单元中用于发送下行信息的最后K个符号,K为正整数。
下行信息可以包括下行控制信息以及下行数据中的至少一种。为了减小时延,一般希望实现网络设备在子帧n的下行符号上进行下行数据传输,用户设备在子帧n的上行符号上向网络设备发送针对在子帧n接收的下行数据的ACK/NACK。如果网络设备将下行数据映射到第一传输时间单元包括的用于传输下行数据符号中的最后K个符号上,则用户设备接收下行数据后需要立即解码并确定针对该下行数据的ACK/NACK,由于用户设备的处理时延,可能在子帧n的第一个用于传输上行控制信息的符号之前无法对子帧n的最后K个符号上接收的下行数据进行解码,所以无法在子帧n向基站发送ACK/NACK。那么为解决该技术问题,本发明实施例中网络设备不通过该最后K个符号向用户设备发送下行数据,那么用户设备就有较为充足的时间对在子帧n接收的下行数据进行解码,从而可以在子帧n向网络设备发送ACK/NACK,减小数据处理时延。
结合第五方面,在第五方面的第一种可能的实现方式中,网络设备在第一传输时间单元中用于发送下行信息的最后K个符号可以向用户设备发送参考信号。
若网络设备发送下行数据未占用该最后K个符号,为了提高传输资源的利用率,则网络设备可以在该最后K个符号上发送其他信息,例如参考信号,这样网络设备可以通过有限的传输资源发送尽可能多的信息。
结合第五方面或第五方面的第一种可能的实现方式,在第五方面的第二种可能的实现方式中,第一传输时间单元包括前L个用于发送下行信息的符号、保护间隔占用的符号、以及后M个用于发送上行信息的符号。其中,最后K个符号为前L个符号中的最后K个符号,L为大于等于K的整数,M为正整数。
该实现方式给出了一种第一传输时间单元的结构。

结合第六方面或第六方面的第一种可能的实现方式至第五种可能的实现方式中的任一种可能的实现方式中,在第六方面的第六种可能的实现方式中,传输时间单元包括一个或多个子帧,或传输时间单元包括一个或多个时隙,或传输时间单元包括一个或多个符号。

结合第七方面,在第七方面的第一种可能的实现方式中,控制信令还指示用户设备将上行控制信息的部分信息映射到第一传输时间单元的最后M个符号上,以及将上行控制信息中剩余的信息映射到第二传输时间单元的前N个符号上。其中,第一传输时间单元和第
二传输时间单元为连续的传输时间单元,M、N均为正整数。则,通信接口用于在至少两个传输时间单元中接收用户设备发送的上行控制信息,通过以下方式实现:在第一传输时间单元的最后M个符号上接收上行控制信息的部分信息,以及在第二传输时间的前N个符号上接收上行控制信息中剩余的信息。

为使本发明实施例的目的、技术方案和优点更加清楚,下面将结合本发明实施例中的附图,对本发明实施例中的技术方案进行清楚、完整地描述,显然,所描述的实施例是本发明一部分实施例,而不是全部的实施例。基于本发明中的实施例,本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例,都属于本发明实施例保护的范围。
以下,对本发明实施例中的部分用语进行解释说明,以便于本领域技术人员理解。
1)用户设备,是指向用户提供语音和/或数据连通性的设备,例如可以包括具有无线连接功能的手持式设备、或连接到无线调制解调器的处理设备。该用户设备可以经无线接入网(Radio Access Network,RAN)与核心网进行通信,与RAN交换语音和/或数据。该用户设备可以包括UE、无线终端设备、移动终端设备、订户单元(Subscriber Unit)、订户站(Subscriber Station),移动站(Mobile Station)、移动台(Mobile)、远程站(Remote Station)、接入点(Access Point,AP)、远程终端设备(Remote Terminal)、接入终端设备(Access Terminal)、用户终端设备(User Terminal)、用户代理(User Agent)、或用户装备(User Device)等。例如,可以包括移动电话(或称为“蜂窝”电话),具有移动终端设备的计算机,便携式、袖珍式、手持式、计算机内置的或者车载的移动装置。例如,个人通信业务(Personal Communication Service,PCS)电话、无绳电话、会话发起协议(SIP)话机、无线本地环路(Wireless Local Loop,WLL)站、个人数字助理(Personal Digital Assistant,PDA)等设备。
2)网络设备,例如包括基站(例如,接入点),可以是指接入网中在空中接口上通过
一个或多个扇区与无线终端设备通信的设备。基站可用于将收到的空中帧与网际协议(IP)分组进行相互转换,作为无线终端设备与接入网的其余部分之间的路由器,其中接入网的其余部分可包括IP网络。基站还可协调对空中接口的属性管理。例如,基站可以包括无线网络控制器(Radio Network Controller,RNC)或基站控制器(Base Station Controller,BSC),或者也可以包括演进的LTE***(LTE-Advanced,LTE-A)中的演进型基站(NodeB或eNB或e-NodeB,evolutional Node B),或者也可以包括5G***中的下一代节点B(next generation node B,NG-NB),本发明实施例并不限定。
3)上行控制信息,可以包括UCI,UCI中包括确认混合自动重传请求(Hybrid Automatic Repeat reQuest,HARQ)中的确认应答(ACK)/否定应答(NACK),还可以包括其他的一些上行方向的控制信息,例如信道状态信息(Channel State Information,CSI)等。
4)本发明实施例中的术语“***”和“网络”可被互换使用。“多个”是指两个或两个以上,鉴于此,本发明实施例中也可以将“多个”理解为“至少两个”。“和/或”,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,字符“/”,如无特殊说明,一般表示前后关联对象是一种“或”的关系。
首先介绍5G***中引入的S1子帧和S2子帧的帧结构。
请参见图1A,为一种S1子帧的帧结构示意图。在这种S1子帧中,包括11个用于下行传输的符号(如图1A中画斜线的方框所示)、时长为1个符号的GP(如图1A中空白的方框所示)以及2个用于上行传输的符号(如图1A中画横线的方框所示)。其中11个用于下行传输的符号中包括用于物理下行控制信道(Physical Downlink Control Channel,PDCCH)传输的符号以及用于物理下行共享信道(Physical Downlink Shared Channel,PDSCH)传输的符号,一般来说用于PDCCH传输的符号位于用于PDSCH传输的符号之前。该S1子帧中的2个用于上行传输的符号可以是用于PUCCH传输的符号。
请参见图1B,为一种S2子帧的帧结构示意图。在这种S2子帧中,包括2个用于下行传输的符号(如图1B中画斜线的方框所示)、时长为1个符号的GP(如图1B中空白的方框所示)以及11个用于上行传输的符号(如图1B中画横线的方框所示)。其中,2个用于下行传输的符号中包括用于PDCCH传输的符号,11个用于上行传输的符号包括用于物理上行共享信道(Physical Uplink Shared Channel,PUSCH)传输的符号以及用于PUCCH传输的符号。或者,很可能S2子帧中不包括用于PUCCH传输的符号,图1B是以包括用于PUCCH传输的符号为例。
下面介绍本发明实施例的应用场景,请参见图2。图2中包括一个网络设备和一个用户设备,其中网络设备以基站为例,基站为用户设备提供服务。在图2中,若采用HARQ技术,则,如果基站通过S1子帧包括的用于下行传输的符号向用户设备发送下行数据,那么用户设备可以继续通过该S1子帧包括的用于上行传输的符号向基站发送针对该下行数据的ACK/NACK,另外用户设备还可以通过该S1子帧包括的用于上行传输的符号向基站发送其他的上行控制信息。
然而S1子帧包括的用于上行传输的符号的数量不会太多,以图1A所示的S1子帧为例,在这种S1子帧中,就只包括2个用于上行传输的符号,显然数量比较少,若用户设备需发送的上行控制信息较多,例如处于小区边缘的用户设备,一般来说需要的用于传输上行控制信息的符号都比较多,那么就可能会出现传输资源不足的情况,导致上行控制信
息无法发送。
为解决该技术问题提出了本发明实施例的技术方案。本发明实施例中,用户设备可以将上行控制信息映射到至少两个传输时间单元中发送,这样上行控制信息可以占用较多的符号,提高了PUCCH的覆盖,特别是当需要传输的上行控制信息较多时,可以有效避免因为没有资源而导致上行控制信息无法传输的情况。
本发明实施例提供的技术方案不仅可以用于5G***及下一代通信***,也可以用于现在的第三代移动通信***(3G)***或***移动通信***(4G)***等通信***,例如在LTE***中也可以应用本发明实施例所提供的技术方案,本发明实施例不作限制。
本发明实施例中,一个传输时间单元可以包括一个或多个时隙,或可以包括一个或多个子帧,或可以包括一个或多个符号。例如,一个传输时间单元可以是一个子帧,如5G***中的S1子帧或S2子帧,或为3G***或4G***里的子帧,例如LTE***里的子帧,通过本发明实施例提供的技术方案都可以增加对于PUCCH的覆盖。在下文的描述过程中,多以传输时间单元是子帧为例。
下面结合说明书附图介绍本发明实施例提供的技术方案,在下面的介绍过程中,均以应用于图2所示的场景为例,以及均以网络设备是基站为例。
请参见图3,本发明一实施例提供一种上行控制信息发送方法,该方法的流程介绍如下。
S31、基站向用户设备发送控制信令,该控制信令用于指示用户设备将上行控制信息映射到至少两个传输时间单元中发送给基站,用户设备接收该控制信令。
基站通过发送控制信令来调度用户设备,该控制信令可以指示用户设备对于上行控制信息的映射方式。该控制信令可以是下行控制信息(Downlink Control Information,DCI),或者也可以是高层信令,例如无线资源控制(Radio Resource Control,RRC)信令,本发明实施例不作限制。
S32、基站向用户设备发送下行数据,则用户设备接收基站发送的下行数据。
若在5G***中,则基站可以通过S1子帧向用户设备发送下行数据,或者可以通过S2子帧向用户设备发送下行数据,或者也可以通过其他类型的传输时间单元向用户设备发送下行数据。若在3G***或4G***中,则基站可以通过相应***中通用的子帧向用户设备发送下行数据。
例如基站通过S1子帧向用户设备发送下行数据,当然在实际应用中不限于此。继续以图1A所示的S1子帧的帧结构为例,则基站可以通过S1子帧中用于PDSCH传输的符号向用户设备发送下行数据,因为S1子帧除了包括用于下行传输的符号之外,还包括用于上行传输的符号,因此用户设备可以继续通过该S1子帧中的用于上行传输的符号向基站发送上行信息。
另外下文中为了简洁,将用于上行传输的符号称为上行符号,将用于下行传输的符号称为下行符号。显然上行符号中包括用于传输上行控制信息的符号和用于传输上行数据的符号,下行符号中包括用于传输下行控制信息的符号和用于传输下行数据的符号。
其中,S32是可选执行的步骤,因此在图3中将用于表示S32的箭头画为虚线,以与必选步骤相区分。
S33、用户设备获取要向基站发送的上行控制信息。
基站向用户设备发送了下行数据,那么用户设备接收下行数据后,可以针对下行数据
的接收情况确定向基站回复ACK还是NACK,也就是说,用户设备要向基站发送的上行控制信息中可以包括ACK/NACK。当然,除了ACK/NACK之外,用户设备可能还会向基站发送其他的上行控制信息,例如CSI等,本发明实施例不作限制。
S34、用户设备将获取的上行控制信息映射到至少两个传输时间单元中发送给基站,那么基站在至少两个传输时间单元中接收用户设备发送的上行控制信息。
关于S34,包括但不限于如下两种实施方式:
1、用户设备将获取的上行控制信息映射到两个连续的传输时间单元中发送给基站,则基站在这两个连续的传输时间单元上接收该上行控制信息。
将两个连续的传输时间单元分别称为第一传输时间单元和第二传输时间单元。作为对这种实施方式的举例,第一传输时间单元可以是S1子帧,第二传输时间单元可以是上行专用子帧。上行专用子帧可以是上行(Uplink)UL子帧,UL子帧的所有符号均用于传输上行信息。其中,UL子帧的所有符号可以全部用于传输上行控制信息,或者可以全部用于传输上行数据,或者也可以部分用于传输上行控制信息,剩余部分用于传输上行数据。本发明实施例中作为第二传输时间单元的上行专用子帧,显然是全部用于传输上行控制信息的上行专用子帧,或者是部分用于传输上行控制信息,剩余部分用于传输上行数据的上行专用子帧。
在这种实施方式中,用户设备将上行控制信息的部分信息映射到第一传输时间单元,以及将上行控制信息中剩余的信息映射到第二传输时间单元,从而在第一传输时间单元和第二传输时间单元上将上行控制信息发送给基站。基站在第一传输时间单元上接收上行控制信息的部分信息,以及在第二传输时间单元上接收上行控制信息中剩余的信息,从而就接收了完整的上行控制信息。即,上行控制信息除了可以占用第一传输时间单元中的上行符号之外,还可以占用第二传输时间单元中的上行符号,显然提高了传输时间单元对于PUCCH的覆盖,使得上行控制信息能够充分得到传输。
优选的,为了使得上行控制信息得以连续传输,可以将上行控制信息的部分信息映射到第一传输时间单元的连续的最后M个符号上,以及将上行控制信息中剩余的信息映射到第二传输时间单元的连续的前N个符号上,则基站在第一传输时间单元的最后M个符号上接收上行控制信息的部分信息,以及在第二传输时间单元的前N个符号上接收上行控制信息中剩余的信息。这样在映射时可以实现连续映射,基站在接收时也可以连续接收,使得发送性能和接收性能都更好。这里的前、后,都是针对时间而言,即按时间顺序的前和后。M、N均为正整数,M和N的取值范围与传输时间单元的结构有关,本发明实施例不作限制。例如第一传输时间单元为S1子帧,那么M可能的取值包括1、2、或3等。其中,究竟将上行控制信息的部分信息映射到第一传输时间单元的哪些符号上,以及将上行控制信息中剩余的信息映射到第二传输时间单元的哪些符号上,即在映射时M和N的取值究竟是多少,可以由协议或标准预定义,或者也可以由基站通过S31中的控制信令通知用户设备。
在将上行控制信息进行映射时,除了需知道上行控制信息在传输时间单元中占用的时域位置外,还需要知道上行控制信息在传输时间单元中占用的频域位置。下面进行介绍。
本发明实施例中,上行控制信息的部分信息在第一传输时间单元中占用的频域位置可以由基站告知用户设备,例如基站通过S31中的控制信息向用户设备指示上行控制信息在第一传输时间单元中占用的频域位置,或者,上行控制信息的部分信息在第一传输时间单
元中占用的频域位置可以由用户设备自行计算,一种计算方式为:用户设备确定接收的下行数据对应的下行控制信息,根据该下行控制信息的第一个控制信道单元(Control Channel Element,CCE)的编号计算得到上行控制信息的部分信息在第一传输时间单元中的频域位置。其中,用于计算频域位置的下行控制信息对应的下行数据,可以是用户设备在第一传输时间单元中接收的下行数据,或者也可能是用户设备在该第一传输时间单元之前的几个传输时间单元中接收的下行数据。如果上行控制信息的部分信息在第一传输时间单元中占用的频域位置需用户设备自行计算,那么基站可以通过S31中的控制信息指示用户设备自行计算上行控制信息的部分信息在第一传输时间单元中占用的频域位置,或者用户设备根据协议或标准的预定义确定需自行按照CCE的编号计算上行控制信息的部分信息在第一传输时间单元中占用的频域位置。
上一段介绍了用户设备如何获知上行控制信息的部分信息在第一传输时间单元中占用的频域位置,以下介绍用户设备如何获知上行控制信息中剩余的信息在第二传输时间单元中占用的频域位置。本发明实施例中,上行控制信息中剩余的信息在第二传输时间单元中占用的频域位置与用户设备是否要在第二传输时间单元中发送上行数据有关。
如果用户设备不在第二传输时间单元中发送上行数据,那么上行控制信息中剩余的信息在第二传输时间单元中占用的频域位置也可以由基站告知用户设备。例如基站通过S31中的控制信息向用户设备指示上行控制信息在第二传输时间单元中占用的频域位置。其中,基站可以直接告知用户设备指示上行控制信息在第二传输时间单元中具体占用的频域位置,或者基站也可以告知用户设备,上行控制信息在第二传输时间单元中占用的频域位置和上行控制信息的部分信息在第一传输时间单元中占用的频域位置相同;或者,上行控制信息中剩余的信息在第二传输时间单元中占用的频域位置与上行控制信息的部分信息在第一传输时间单元中占用的频域位置可以相差第一偏移量,那么,基站可以通过S31中的控制信令指示用户设备,两个频域位置相差第一偏移量,则用户设备在获得上行控制信息的部分信息在第一传输时间单元中占用的频域位置后,就可以根据上行控制信息的部分信息在第一传输时间单元中占用的频域位置和第一偏移量得到上行控制信息中剩余的信息在第二传输时间单元中占用的频域位置。其中,第一偏移量可以是基站告知用户设备的,或者可以是标准或协议预定义的,或者可以是用户设备根据第一传输时间单元的编号计算得到的,或者可以是用户设备根据第二传输时间单元的编号计算得到的。
无论用户设备如何获得上行控制信息中剩余的信息在第二传输时间单元中占用的频域位置,在用户设备不在第二传输时间单元中发送上行数据的情况下,上行控制信息的部分信息在第一传输时间单元中占用的频域位置和上行控制信息中剩余的信息在第二传输时间单元中占用的频域位置可以相同也可以不同,在不同的情况下,一种可能的实施方式为二者相差第一偏移量。
如果用户设备不在第二传输时间单元中发送上行数据,那么上行控制信息中剩余的信息在第二传输时间单元中占用的频域位置可以是第二传输时间单元中的连续的P个子载波,其中,P个子载波包括在第二传输时间单元中分配给用户设备的上行时频资源中编号最小的子载波,或P个子载波中包括在第二传输时间单元中分配给用户设备的上行时频资源中编号最大的子载波,P为正整数。可以理解为,将上行控制信息中剩余的信息映射到分配给用户设备的上行时频资源的频域边缘位置,尽量不占用中心频域位置,在保证上行控制信息中剩余的信息连续映射的同时尽量不影响其他上行信息在频域的连续映射。其中,P
个子载波究竟是在第二传输时间单元中分配给用户设备的上行时频资源中的哪些子载波,可以由基站通知用户设备,例如基站通过S31中的控制信令一并通知用户设备,或者可以由协议或标准预定义。这种情况下,如果用户设备要在第二传输时间单元的前N个符号中映射上行数据,这些上行数据在频域上占据P个子载波,那么上行控制信息中剩余的信息也就是携带在第二传输时间单元中的上行数据中一并发送的,在发送数据的同时可以一并发送上行控制信息,既不影响数据的发送,也增加了发送上行控制信息的符号数。
在本发明实施例中,上行控制信息的部分信息在第一传输时间单元中占用的子载波的数量和上行控制信息中剩余的信息在第二传输时间单元中占用的子载波的数量相同,例如都占用6个子载波或都占用12个子载波等。
2、用户设备将上行控制信息重复映射到至少两个传输时间单元中,以将至少两个上行控制信息发送给基站,也就是将上行控制信息重复发送给基站。其中,至少两个传输时间单元可以是连续的传输时间单元,也可以是不连续的传输时间单元,另外,至少两个传输时间单元的类型可以相同,例如同为S1子帧或同为S2子帧,或者至少两个传输时间单元的类型也可以不同,例如其中一个传输时间单元为S1子帧,其中另一个传输时间单元为UL子帧,等等。
也就是说,在如前介绍的第1种实施方式中,通过一个传输时间单元传输的是上行控制信息的部分信息,基站在两个连续的传输时间单元上接收一个完整的上行控制信息。而在第2种实施方式中,通过一个传输时间单元传输的是完整上行控制信息,基站在至少两个传输时间单元上接收至少两个完整的上行控制信息,也就是基站通过每个传输时间单元都可以接收一个完整的上行控制信息,相当于重复发送。
在这种方式下,可以将上行控制信息映射到传输时间单元中的上行符号中进行发送,映射方式不多赘述。
本发明实施例中,至少两个传输时间单元究竟是哪些传输时间单元,可以由基站通知用户设备,例如基站通过S31中的控制信令将至少两个传输时间单元的编号告知用户设备,或者可以由协议或标准预定义,那么基站只需通过S31中的控制信令告知用户设备采用哪种映射方式,若采用第2种实施方式所示的映射方式,则用户设备根据预定义的信息就知晓至少两个传输时间单元应如何选取。例如预定义,S1子帧后的第一个S1子帧重复发送上行控制信息。
本发明实施例中,重复发送的次数,也就是至少两个子帧的数量,可以由基站告知用户设备,例如基站通过S31中的控制信令告知用户设备,或者可以通过协议或标准预定义,例如预定义,只要采用重复发送的方式,则重复发送的次数为2次。
本发明实施例中,允许进行重复发送的子帧类型可以由基站告知用户设备,例如基站通过S31中的控制信令告知用户设备,或者可以通过协议或标准预定义,例如预定义S1子帧、S2子帧、以及UL子帧均可以参与重复发送。
在这种实施方式中,可以在至少两个传输时间单元重复发送上行控制信息,提升PUCCH的覆盖。特别是在信道状态比较差的情况下,通过多次重复发送也可以提高上行控制信息的发送成功率。
通过本发明实施例提供的技术方案,无论是通过连续的两个传输时间单元发送上行控制信息还是重复发送上行控制信息,都可以增加用于发送上行控制信息的符号数,提高PUCCH的覆盖。
在传输时间单元中,可能包括多个用于传输上行控制信息的符号,例如S1子帧里可能包括2个或3个。那么用户设备在发送上行控制信息时,涉及到如何映射的问题,即需要知道具体将上行控制信息映射到哪些符号上发送。为解决该技术问题,本发明一实施例提供一种上行控制信息发送方法,请参见图4。
S41、基站向用户设备发送控制信令,该控制信令用于指示用户设备将上行控制信息映射到第一传输时间单元包括的符号集合中的全部符号上或部分符号上发送给基站,则用户设备接收该控制信令。其中,该符号集合包括第一传输时间单元的最后M个符号,M为正整数。
例如第一传输时间单元为S1子帧,则最后M个符号可以是S1子帧包括的用于传输上行控制信息的全部符号。
基站通过发送控制信令来调度用户设备,该控制信令可以指示用户设备对于上行控制信息的映射方式。该控制信令可以是DCI,或者也可以是高层信令,例如RRC信令,本发明实施例不作限制。
S42、用户设备获取要向基站发送的上行控制信息。
基站向用户设备发送了下行数据,那么用户设备接收下行数据后,可以针对下行数据的接收情况确定向基站回复ACK还是NACK,也就是说,用户设备要向基站发送的上行控制信息中可以包括ACK/NACK。当然,除了ACK/NACK之外,用户设备可能还会向基站发送其他的上行控制信息,例如CSI等,本发明实施例不作限制。
S43、用户设备将获取的上行控制信息映射到第一传输时间单元的符号集合中的全部符号上发送给基站,则基站在第一传输时间单元的符号集合中的全部符号上接收上行控制信息。或,用户设备将上行控制信息映射到第一传输时间单元的符号集合中的部分符号上发送给基站,则基站在第一传输时间单元的符号集合中的部分符号上接收上行控制信息。其中,用户设备是根据基站发送的控制信令所指示的方式进行的映射。
以第一传输时间单元是图1A所示的S1子帧为例。该S1子帧包括2个用于发送上行控制信息的符号,即该S1子帧的最后2个符号,则该S1子帧的符号集合就可以包括该S1子帧的最后2个符号。那么,基站可以通过控制信令指示用户设备将上行控制信息映射到S1子帧的倒数第二个符号上,或者基站可以通过控制信令指示用户设备将上行控制信息映射到S1子帧的最后一个符号上,或者基站可以通过控制信令指示用户设备将上行控制信息映射到S1子帧的最后2个符号上,即,基站可以根据不同的情况指示用户设备采用不同的映射方式,较为灵活。
使用S1子帧,可以实现基站在子帧n的下行符号上进行下行数据传输,用户设备在子帧n的上行符号上向基站发送针对在子帧n接收的下行数据的ACK/NACK,那么,如果用户设备发送的是NACK,则一般希望基站能够在子帧n+1进行数据重传。一般来说,S1子帧包括的用于传输上行控制信息的符号都位于S1子帧的最后,可参见图1A所示,那么,如果用户设备将ACK/NACK等上行控制信息映射到S1子帧的最后M个符号上发送给基站,由于基站的处理时延,可能在子帧n+1的第一个符号之前无法对子帧n的最后M个符号上接收的ACK/NACK进行解码,所以无法在子帧n+1进行重传。其中,M为正整数,M的取值范围与传输时间单元的结构有关,本发明实施例不作限制。例如对于S1子帧,那么M可能的取值包括1、2、或3等。
为了解决该问题,基站可以根据实际情况来确定对于不同的用户设备应采用何种映射
方式。例如,对于一些对时延较敏感的用户设备,也就是对于时延的要求较高的用户设备,例如进行超高可靠性与超低时延业务(Ultra Reliable&Low Latency Communication,URLLC)业务的用户设备,这种用户设备一般都需要基站在子帧n+1重传子帧n中的下行数据。则基站可以指示此类用户设备将上行控制信息映射到第一传输时间单元包括的符号集合中的部分符号上,例如第一传输时间单元包括M个用于传输上行控制信息的符号,且这M个符号为第一传输时间单元的最后M个符号,则,基站指示此类用户设备映射上行控制信息的符号中不包括第一传输时间单元的最后H个符号,H为小于M的正整数。也就是说,不通过第一传输时间单元的最后H个符号发送上行控制信息,给予基站比较充分的解码时间,从而尽量保证基站能够在子帧n+1重传子帧n中的下行数据。以第一传输时间单元是图1A所示的S1子帧为例,则M=2,那么此时H=1,即用户设备将上行控制信息映射到该S1子帧的倒数第二个符号上发送给基站,而不映射到该S1子帧的最后一个符号上。
或者,对于一些对时延不敏感的用户设备,也就是对时延要求不高的用户设备,例如进行增强的移动宽带业务(enhanced Mobile BroadBand,eMBB)业务的用户设备,这种用户设备一般都不要求基站一定在子帧n+1重传子帧n中的下行数据。则基站可以指示此类用户设备将上行控制信息映射到第一传输时间单元包括的符号集合中的全部符号上或部分符号上,若映射到部分符号上,也不限制究竟是哪些符号。例如第一传输时间单元包括M个用于传输上行控制信息的符号,且这M个符号为第一传输时间单元的最后M个符号,则,基站指示此类用户设备映射上行控制信息的符号为这M个符号中的任意一个或多个符号。当然最好映射到连续的符号上,便于基站接收。以第一传输时间单元是图1A所示的S1子帧为例,则M=2,则用户设备可以将上行控制信息映射到该S1子帧的倒数第二个符号上发送给基站,或者用户设备可以将上行控制信息映射到该S1子帧的最后一个符号上发送给基站,或者用户设备可以将上行控制信息映射到该S1子帧的最后2个符号上发送给基站。
如果基站指示用户设备将上行控制信息映射到第一传输时间单元的部分符号上发送给基站,那么第一传输时间单元所包括的用于发送上行控制信息的符号中可能有一部分没有映射上行控制信息,如果这部分符号不承载任何信息,则也是资源的浪费。因此本发明实施例中,如果基站指示用户设备将上行控制信息映射到第一传输时间单元的部分符号上发送给基站,那么基站还可以通过S41中的控制信令指示用户设备在第一传输时间单元的符号集合中未映射上行控制信息的符号上向基站发送参考信号,这样使得第一传输时间单元的符号都能够得到充分利用,避免资源浪费。这里的参考信号可以是探测参考信号(Sounding Reference Signal,SRS),当然也可以是其他可能的参考信号。或者,如果基站指示用户设备将上行控制信息映射到第一传输时间单元的部分符号上发送给基站,则用户设备可以根据标准或协议预定义的规则确定在第一传输时间单元的符号集合中未映射上行控制信息的符号上向基站发送参考信号,无需基站额外指示。其中,第一传输时间单元中的参考信号所占用的频域位置可以与上行控制信息所占用的频域位置相同,或者第一传输时间单元中的参考信号在频域上可以占用在第一传输时间单元中为用户设备分配的整个上行频域资源。
以第一传输时间单元是图1A所示的S1子帧为例,则M=2,用户设备根据基站的指示,将上行控制信息映射到该S1子帧的倒数第二个符号上发送给基站,用户设备还可以
根据基站的指示或根据协议或标准预定义的规则,将参考信号映射到该S1子帧的最后一个符号上发送给基站,则S1子帧的各个符号都能得到有效利用,也就是说,可以通过尽量少的传输时间单元传输尽量多的信息。
通过本发明实施例提供的技术方案,用户可以采用合理的映射方式映射上行控制信息,且对于一些对时延敏感的用户设备,可以尽量实现基站初传在子帧n,基站重传在子帧n+1,满足时延需求,且还可以尽量避免时频资源的浪费。
使用S1子帧,可以实现基站在子帧n的下行符号上进行下行数据传输,用户设备在子帧n的上行符号上向基站发送针对在子帧n接收的下行数据的ACK/NACK。以图1A所示的S1子帧为例,如果基站将下行数据映射到S1子帧包括的用于传输下行数据符号中的最后K个符号上,则用户设备接收下行数据后需要立即解码并确定针对该下行数据的ACK/NACK,由于用户设备的处理时延,可能在子帧n的第一个用于传输上行控制信息的符号之前无法对子帧n的最后K个符号上接收的下行数据进行解码,所以无法在子帧n向基站发送ACK/NACK。其中,K为正整数,K可以小于等于S1子帧包括的用于传输下行数据的符号数。
为解决该技术问题,本发明一实施例提供一种下行信息发送方法,请参见图5。
S51、基站获取要向用户设备发送的下行信息。
基站要向用户设备发送的下行信息中可以包括下行数据,也可以包括下行控制信息。
S52、基站在第一传输时间单元向用户设备发送该下行信息。
其中,第一传输时间单元包括前L个用于发送下行信息的符号、GP占用的符号、以及后M个用于发送上行信息的符号,其中M为正整数。第一传输时间单元若以图1A所示的S1子帧为例,那么L=11,即S1子帧的前11个符号,GP占用的符号为1,M=2,也就是最后2个符号。
基站可以通过前L个符号向用户设备发送下行信息,但如果基站在发送下行信息时占用了前L个符号中的最后K个符号,则用户设备在接收最后K个符号上的下行信息后可能来不及解码,从而可能无法在第一传输时间单元的最后M个符号上向基站反馈针对该下行信息的上行控制信息。其中,K为正整数,L为大于等于K的整数。因此本发明实施例中,基站向用户设备发送下行信息时,可以不在前L个符号中的最后K个符号上发送,即,不将上行控制信息映射到前L个符号中的最后K个符号上,而只是通过前L个符号中除最后K个符号之外剩余的符号向用户设备发送下行信息,那么用户设备接收下行信息后可以有较为充足的时间进行解码,从而可以在第一传输时间单元的最后M个符号上向基站发送针对该下行信息的上行控制信息。其中K的取值与传输时间单元的结构有关,也与用户设备的解码能力等有关,可以由基站告知用户设备,或者也可以通过协议或标准预定义,本发明实施例不作限制。
以图1A所示的S1子帧为例,且以K=1为例。该S1子帧的前11个符号用于发送下行信息,则基站在映射下行数据时,选择不将下行数据映射到该11个符号中的最后一个符号上,则用户设备接收下行数据后,可以有较为充足的时间来解码,并确定针对接收的下行数据的ACK/NACK,从而可以在该S1子帧的最后2个符号上向基站发送该ACK/NACK,从而实现了及时反馈,便于基站尽快确定是继续传新数据还是重传。
如果基站在映射下行信息时不映射到第一传输时间单元的前L个符号的最后K个符号上,那么最后K个符号不会映射下行信息,可能就会处于空闲状态,如果这部分符号不承
载任何信息,则也是资源的浪费。因此本发明实施例中,如果基站在映射下行信息时不映射到第一传输时间单元的前L个符号的最后K个符号上,那么基站还可以在该最后K个符号上映射参考信号,这样使得第一传输时间单元的符号都能够得到充分利用,避免资源浪费。这里的参考信号可以是信道状态信息参考信号(Channel State Information Reference Signal,CSI-RS),当然也可以是其他可能的参考信号。
通过本发明实施例提供的技术方案,可以实现基站传输在子帧n,用户设备反馈也在子帧n,且可以尽量避免时频资源的浪费。
