- the HARQ-ACK may determine the time domain position (including the time slot and the symbol position in the time slot) of the transmission according to the dynamic feedback timing or the fixed feedback timing.
- the so-called dynamic feedback timing means that there is an indication field in the DCI that schedules the downlink transmission to indicate the interval between the time slot where the downlink transmission is located and the time slot where the HARQ-ACK feedback information is transmitted.

- multiplexing transmission rules between different UCIs are defined, for example: when PUCCH carrying HARQ-ACK overlaps with PUCCH carrying SR, If both the PUCCH carrying HARQ-ACK and the PUCCH carrying SR are format 1 PUCCH, then when SR is negative, HARQ-ACK is transmitted on the PUCCH resource corresponding to HARQ-ACK to implicitly express SR as negative; when SR is When positive, as shown in Figure 1, the HARQ-ACK is transferred to the PUCCH resource corresponding to the SR and transmitted to implicitly express that the positive SR also exists.
- the SPS HARQ-ACK when the PUCCH carrying the semi-persistent scheduling SPS HARQ-ACK (that is, the HARQ-ACK corresponding to the SPS PDSCH) overlaps with the PUCCH carrying the CSI, as shown in FIG. 2, the SPS HARQ-ACK is transferred to the PUCCH resource corresponding to the CSI Multiplex transmission with CSI.

为使本公开要解决的技术问题、技术方案和优点更加清楚,下面将结合具体实施例及附图进行详细描述。
为使本领域技术人员能够更好地理解本公开实施例的技术方案,先进行如下说明。
下行控制信息UCI至少包括混合自动重传请求确认HARQ-ACK、信道状态信息CSI以及调度请求SR。其中HARQ-ACK可以是按照动态的反馈时序或固定的反馈时序确定传输的时域位置(包括时隙以及时隙内的符号位置)。所谓动态的反馈时序即调度下行传输的DCI中存在指示域指示下行传输所在的时隙到传输其HARQ-ACK反馈信息的时隙之间的间隔,在该时隙中的具体符号位置则根据DCI中的指示域从高层信令预先配置的多个PUCCH资源中确定一个。所谓固定的反馈时序则是由高层信令直接配置一个下行传输所在的时隙到传输其HARQ-ACK反馈信息的时隙之间的间隔的值。不论动态的反馈时序还是固定的反馈时序,都是基于下行传输所在的时隙的结束位置来确定HARQ-ACK反馈所在的时隙,当下行传输是动态调度的时候,HARQ-ACK反馈所在的时隙也是随之动态改变的。
CSI和SR在PUCCH上的传输资源则是由高层信令预先配置的,并且按照根据预先配置的周期和偏移确定的传输机会进行周期传输,因此其传输的时域位置相对固定。一个CSI report的传输周期不短于1个时隙,但一个时隙中可以存在多个不同的CSI report。一个SR配置的传输周期最短可以为2个符号,因此,一个时隙中可以存在对应同一个SR配置的多个SR传输周期,此外还可以配置多个SR配置,每个SR配置的传输周期和偏移都是独立配置的,因此,可能在一个时隙中时分复用TDM存在多个SR配置的传输机会。
在NR R15***中,当承载不同UCI的PUCCH之间存在时域资源重叠时,定义了不同UCI之间的复用传输规则,例如:当承载HARQ-ACK的PUCCH与承载SR的PUCCH重叠时,如果承载HARQ-ACK的PUCCH与承载SR的PUCCH都为格式1PUCCH,则当SR为否定negative时,HARQ-ACK在HARQ-ACK对应的PUCCH资源上传输,来隐式表达SR为negative;当SR为肯定positive时,如图1所示,将HARQ-ACK转移到SR对应的PUCCH资源上传输,来隐式表达同时存在positive SR。又例如:当承载半持续调度SPS HARQ-ACK(即对应SPS PDSCH的HARQ-ACK)的PUCCH与承载CSI的PUCCH重叠时,如图2所示,将SPS HARQ-ACK转移到CSI对应的PUCCH资源上与CSI复用传输。又例如:当承载dynamic HARQ-ACK(即对应具有对应的DCI调度的PDSCH的HARQ-ACK)的 PUCCH与承载CSI的PUCCH重叠且PUCCH资源集合配置了超过1个时,如图3所示,根据HARQ-ACK和CSI的比特数,在配置的PUCCH资源集合中选择一个集合,再根据调度PDSCH的DCI中的PUCCH资源指示域从选择的一个集合中确定出一个PUCCH资源,用于同时承载HARQ-ACK和CSI。
然而,在R16URLLC中,当按照URLLC UCI的传输机制确定的承载URLLC UCI的上行信道与按照eMBB UCI的传输机制确定的承载eMBB UCI的上行信道之间存在重叠时,按照相关技术中的复用规则传输复用传输UCI时,会增加UCI传输时延。
基于此,如图4所示,本公开实施例提供了一种信息传输方法,应用于终端,包括:
步骤401:在承载第一上行控制信息UCI的第一上行信道与承载第二UCI的第二上行信道在时域上重叠的情况下,确定用于所述第一UCI和所述第二UCI复用传输的第三上行信道。
其中,所述第三上行信道为所述第一上行信道或所述第二上行信道;
或者,所述第三上行信道为除所述第一上行信道和第二上行信道之外的上行信道。
本公开实施例中,上述第三上行信道可以是根据相关技术中的UCI复用规则确定的上行信道,对于UCI在不同PUCCH上的重叠,根据UCI复用规则,确定的第三上行信道可能是第一上行信道或者第二上行信道中的一个,也可能是一个新的上行信道,具体取决于是何种UCI以及何种PUCCH格式之间的重叠;该第三上行信道可为物理上行控制信道PUCCH和物理上行共享信道PUSCH中的至少一种,即如果是PUCCH之间的重叠,确定的第三上行信道还是PUCCH,如果是PUCCH和PUSCH之间的重叠,确定的第三上行信道可以是PUSCH。
步骤402:判断所述第三上行信道的起始和/或结束位置是否晚于所述第一上行信道的起始和/或结束位置预设时间。
所述预设时间为第一预设数量个正交频分复用OFDM符号;
或者,所述预设时间为第一预设数量个OFDM符号对应的时间长度;
或者,所述预设时间为第二预设数量个时间单位对应的时长。
例如,所述预设时间在表现为时间长度时,时间长度的单位可具体为毫秒,此时时间长度的计算可以是依据一个参考的子载波间隔计算的,或者根据预定规则选择的多个子载波间隔中的一个计算的,其中多个子载波间隔具体为PDSCH对应的子载波间隔、PDCCH对应的子载波间隔、PUCCH对应的子载波间隔、PUSCH对应的子载波间隔中的至少两个。
例如,所述预设时间可以是大于0的,也可以是等于0的,当等于0时,意味着起始和/或结束位置对齐(即相同)。
例如,所述预设时间可以是一个,也可以是多个,例如当需要同时判断两处位置是否满足预设时间是,对不同位置进行判断的预设时间可以相同,也可以不同。
在本公开的具体实施例中,判断所述第三上行信道的起始和/或结束位置是否晚于所述第一上行信道的起始和/或结束位置预设时间,包括:
判断所述第三上行信道的起始位置是否晚于所述第一上行信道的起始位置预设时间;
或者,判断所述第三上行信道的结束位置是否晚于所述第一上行信道的结束位置预设时间;
或者,判断所述第三上行信道的结束位置是否晚于所述第一上行信道的起始位置预设时间;
或者,判断所述第三上行信道的起始位置是否晚于所述第一上行信道的结束位置预设时间;
或者,判断所述第三上行信道的起始位置是否晚于所述第一上行信道的起始位置预设时间,以及判断所述第三上行信道的结束位置是否晚于所述第一上行信道的结束位置预设时间。此处,对起始位置进行判断的预设时间与对结束位置进行判断的预设时间可以相同,或者不同。
步骤403:当判断为是时,丢弃所述第二UCI,在所述第一上行信道上传输所述第一UCI。
这里,第三上行信道的起始和/或结束位置晚于第一上行信道的起始和/或结束位置预设时间是指第三上行信道的起始和/或结束位置位于所述第一上行信道的起始和/或结束位置之后,且第三上行信道的起始和/或结束位置与 所述第一上行信道的起始和/或结束位置的时间间隔大于预设时间。
其中,所述第一UCI和所述第二UCI的类型相同或者不同。例如可以都是SR,或者可以都是CSI,或者可以都是HARQ-ACK,也可以是一种为HARQ-ACK,另一种为SR或CSI;或一种为CSI,另一种为SR等。
这里,第一UCI的优先级或重要性高于所述第二UCI;
或者,所述第一UCI为第一业务类型对应的UCI,所述第二UCI为第二业务类型对应的UCI,且所述第一业务类型的优先级或重要性高于所述第二业务类型。例如,第一UCI为URLLC对应的UCI,所述第二UCI为eMBB对应的UCI。
或者,所述第一UCI和所述第二UCI为同一种业务类型中具有不同优先级或重要性的UCI。例如,第一UCI为URLLC的HARQ-ACK,第二UCI为URLLC的CSI和/或SR。
进一步地,判断所述第三上行信道的起始和/或结束位置是否晚于所述第一上行信道的起始和/或结束位置预设时间之后,还包括:
当判断为否时,在所述第三上行信道上传输所述第一UCI和所述第二UCI,或者,在所述第三上行信道上传输所述第一UCI。
这里,当在所述第三上行信道上传输所述第一UCI时,第二UCI是隐式传输的,例如通过使用第三上行信道传输,可以隐式表达同时存在第二UCI。

例如,第一业务类型或第一UCI对应第一DCI格式,第二业务类型或第二UCI对应第二DCI格式,预先规定对应第一DCI格式的业务类型的优先级高于对应第二DCI格式的业务类型的优先级,或者,预先规定对应第一DCI格式的UCI的优先级高于对应第二DCI格式的UCI的优先级,则根据对应的 DCI格式,可确定第一业务类型的优先级高于第二业务类型的优先级,或者第一UCI的优先级高于第二UCI的优先级。
又例如,第一业务类型或第一UCI对应第一RNTI,第二业务类型或第二UCI对应第二RNTI,预先规定对应第一RNTI的业务类型的优先级高于对应第二RNTI的业务类型的优先级,或者预先约定对应第一RNTI的UCI(即其对应的下行传输使用第一RNTI加扰)的优先级高于对应第二RNTI的UCI的优先级,则根据对应的RNTI,可确定第一业务类型的优先级高于第二业务类型的优先级,或者第一UCI的优先级高于第二UCI的优先级。
又例如,第一业务类型或第一UCI对应的DCI在第一CORESET或第一搜索空间中传输,第二业务类型或第二UCI对应的DCI在第二CORESET或第二搜索空间中传输,预先规定对应第一CORESET或第一搜索空间的业务类型的优先级高于对应第二CORESET或搜索空间的业务类型的优先级,或者,预先规定对应第一CORESET或第一搜索空间的UCI(即其调度信息在该CORESET或搜索空间中传输)的优先级高于对应第二CORESET或搜索空间的UCI的优先级,则根据对应的CORESET或搜索空间,可确定第一业务类型的优先级高于第二业务类型的优先级,或者第一UCI的优先级高于第二UCI的优先级。
又例如,第一业务类型或第一UCI对应的目标BLER为10-5或10-6,第二业务类型或第二UCI对应的目标BLER高于10-5或10-6(例如10-2或10-1),预先规定对应目标BLER为10-5或10-6的业务类型的优先级高于对应目标BLER为10-2或10-1的业务类型的优先级,或者,预先规定对应目标BLER为10-5或10-6的UCI的优先级高于对应目标BLER为10-2或10-1的UCI的优先级,则根据对应的目标BLER,可确定第一业务类型的优先级高于第二业务类型的优先级,或者第一UCI的优先级高于第二UCI的优先级。

本公开实施例的信息传输方法,在承载第一UCI的第一上行信道与承载第二UCI的第二上行信道在时域上重叠的情况下,确定用于所述第一UCI和所述第二UCI复用传输的第三上行信道;判断所述第三上行信道的起始和/或结束位置是否晚于所述第一上行信道的起始和/或结束位置预设时间;当判断为是时,不接收所述第二UCI,在所述第一上行信道上接收所述第一UCI,以保证高优先级或高重要性的UCI传输的时延。
下面结合具体实施例来对本公开实施例的信息传输方法进行说明。
实施例1:如图6和图7所示,假设一个时隙中存在两个PUCCH,不同PUCCH承载不同类型的UCI,假设根据调度下行传输的DCI的格式、DCI大小、传输所在的搜索空间、传输所在的CORESET、传输所使用的波束beam或传输使用的RNTI等信息可以确定,该下行传输对应URLLC业务,或者确定该下行传输的优先级较高,则可以确定该下行传输的HARQ-ACK为第一UCI,即优先级较高的UCI,同理,例如根据PUCCH资源的配置或者SR的配置,可以确定该SR为对应eMBB的SR,或者确定该SR的优先级较低,则可以确定SR为第二UCI,即优先级较低的UCI。
假设HARQ-ACK和SR都使用PUCCH格式1传输,则由于两个PUCCH之间在时域上重叠,按照UCI复用传输规则,当SR为positive SR时,需要将HARQ-ACK转移到SR对应的PUCCH资源上传输,即确定SR对应的PUCCH资源为进行HARQ-ACK和SR复用传输的PUCCH资源。
终端需要进行如下判断:判断SR对应的PUCCH资源的最后一个符号是否晚于原HARQ-ACK对应的PUCCH资源的最后一个符号T个符号;假设T为2个符号,如果是,如图6所示,则不传输SR(即丢弃SR),在原承载HARQ-ACK的PUCCH资源上传输HARQ-ACK,以保证高优先级UCI的传输时延不增加,如果否,如图7所示,则可以将HARQ-ACK转移到SR对应 的PUCCH资源上传输,从而支持SR和HARQ-ACK的同时传输,其中SR是通过使用SR对应的PUCCH资源传输来隐式表达的。
当然,其他判断方式,例如判断SR对应的PUCCH资源的第一个符号是否晚于原HARQ-ACK对应的PUCCH资源的第一个符号T个符号,或者判断SR对应的PUCCH资源的第一个符号是否晚于原HARQ-ACK对应的PUCCH资源的最后一个符号T个符号,或者判断SR对应的PUCCH资源的最后一个符号是否晚于原HARQ-ACK对应的PUCCH资源的第一个符号T个符号等方式,以及将上述T个符号替换为对应的时间长度,例如T1毫秒等,均与上述判断方式的实现原理相同,此处不再赘述,预先约定或协议中规定好一种终端和基站之间统一的判断方式即可。
基站侧按照上述同终端一致的判断方法,判断SR对应的PUCCH资源的最后一个符号是否晚于原HARQ-ACK对应的PUCCH资源的最后一个符号T个符号,并根据判断结果确定HARQ-ACK是否会转移到SR资源上传输。当确定不会时,则只在HARQ-ACK对应的PUCCH资源上接收HARQ-ACK;当确定会转移时,因为基站不确定终端是否存在positive SR发送,基站需要在HARQ-ACK对应的PUCCH资源和SR对应的PUCCH资源上进行盲检侧,当在SR对应的PUCCH资源上检测到信息,则确定存在positive SR,从而进一步在SR对应的PUCCH资源上接收得到HARQ-ACK;当在SR对应的PUCCH资源上未检测到信息,则确定不存在positive SR,从而进一步接收在HARQ-ACK对应的PUCCH资源上接收HARQ-ACK。
上述实施例1中,如果将HARQ-ACK替换为SPS HARQ-ACK,将SR替换为CSI,同样适用,其中HARQ-ACK所使用的PUCCH格式与上述实施例1可以相同或者不同,CSI所使用的PUCCH格式可以为PUCCH格式2/3/4等,其他处理同实施例1;上述实施例1中,如果将SR和HARQ-ACK的优先级交换,改变PUCCH格式,同样适用,所不同的是,如果判断结果为是,则不传输HARQ-ACK,只传输SR。
实施例2:如图8和图9所示,假设一个时隙中存在两个PUCCH,不同PUCCH承载不同类型的UCI,假设根据调度下行传输的DCI的格式、DCI大小、传输所在的搜索空间、传输所在的CORESET、传输所使用的波束beam 或传输使用的RNTI等信息可以确定,该下行传输对应URLLC业务,或者确定该下行传输的优先级较高,则可以确定该下行传输的HARQ-ACK为第一UCI,即优先级较高的UCI,同理,例如根据PUCCH资源的配置或者CSI的配置,可以确定该CSI为对应eMBB的CSI,或者确定该CSI的优先级较低,则可以确定CSI为第二UCI,即优先级较低的UCI。
假设配置了多个PUCCH资源集合,即PUCCH资源中存在可以承载较大比特数的资源,由于PUCCH之间在时域上重叠,按照UCI复用传输规则,需要根据HARQ-ACK和CSI的比特数之和选择一个PUCCH资源集合,再根据调度HARQ-ACK所对应的下行传输的DCI中的PUCCH资源指示域确定该PUCCH资源集合中的一个PUCCH资源用于承载HARQ-ACK和CSI,即确定该新PUCCH资源为进行HARQ-ACK和CSI复用传输的PUCCH资源。
终端需要进行如下判断:判断该新PUCCH资源的最后一个符号是否晚于原HARQ-ACK对应的PUCCH资源的最后一个符号T个符号;假设T为2个符号,如果是,如图8所示,则不传输CSI(即丢弃CSI),在原承载HARQ-ACK的PUCCH资源上传输HARQ-ACK,以保证高优先级UCI的传输时延不增加;如果否,如图9所示,则可以将HARQ-ACK和CSI在该新PUCCH资源上同时传输。
当然,其他判断方式,例如判断新PUCCH资源的第一个符号是否晚于原HARQ-ACK对应的PUCCH资源的第一个符号之后T个符号,或者判断新PUCCH资源的第一个符号是否晚于原HARQ-ACK对应的PUCCH资源的最后一个符号之后T个符号,或者判断新PUCCH资源的最后一个符号是否晚于原HARQ-ACK对应的PUCCH资源的第一个符号之后T个符号等方式,以及将上述T个符号替换为对应的时间长度,例如T1毫秒等,均与上述判断方式的实现原理相同,此处不再赘述,预先约定或协议中规定好一种终端和基站之间统一的判断方式即可。
基站侧按照上述同终端一致的判断方法,判断新PUCCH资源的最后一个符号是否晚于HARQ-ACK对应的PUCCH资源的最后一个符号T个符号,并根据判断结果确定是否会使用新PUCCH资源同时传输HARQ-ACK和CSI,当确定不会在新PUCCH资源上传输时,则只在HARQ-ACK对应的PUCCH 资源上接收HARQ-ACK,确定CSI被丢弃了,不需要接收CSI,当确定会在新PUCCH资源上传输时,在新PUCCH资源上同时接收HARQ-ACK和CSI。
上述实施例中仅以UCI在PUCCH上的传输为例,当UCI在PUSCH上传输时,同样适用,当其中一个UCI在PUCCH上传输,另一个UCI在PUSCH上传输时,同样适用。上述实施例中仅以第一UCI和第二UCI为不同类型的UCI为例,当第一UCI和第二UCI都为HARQ-ACK,或者都为CSI,或者都为SR时,同样适用。
本公开实施例的信息传输方法,当第一UCI与第二UCI的传输资源在时域上重叠时,按照复用传输资源与原UCI的传输资源的相对位置确定是否启用复用传输资源传输第一UCI和第二UCI,还是丢弃其中一种UCI,以保证UCI传输的低时延特性。
