Description

上行控制信息传输方法及装置、设备和存储介质 技术领域
本申请涉及通信技术领域,尤其涉及一种上行控制信息传输方法及装置、设备和存储介质。
背景技术
第五代移动通信(5th Generation,5G)技术中定义了超可靠低时延通信(Ultra-Reliable Low-latency communications,URLLC)业务,对业务数据传输的可靠性和时延特性提出了更高的要求。
为了更好的支持URLLC业务,第三代合作伙伴计划(3rd Generation Partnership Project)的版本16(Release 16,R16)中,针对上行控制信息(Uplik Control Information,UCI),引入了优先级处策略。具体地,当承载不同优先级UCI的物理上行控制信道(Physical Uplink Control CHannel,PUCCH)在时域资源上重叠时,终端设备会优先保障高优先级UCI的传输,即终端设备只传输高优先级的UCI,丢弃低优先级的UCI。
为了降低丢弃低优先级UCI对系统效率造成的影响,3GPP的Release 17讨论中,支持将时域资源重叠的不同优先级UCI进行复用传输。然而,如何对不同优先级的UCI进行复用传输,目前还没有明确的方法。

具体实施方式
为使本申请的目的、技术方案和优点更加清楚,下面将结合附图对本申请实施方式作进一步地详细描述,所附附图仅供参考说明之用,并非用来限定本发明实施例。
需要说明的是,本申请的说明书和权利要求书及上述附图中的术语“第一”、“第二”等是用于区别不同对象,而不是用于描述特定顺序。此外,术语“包括”和“具有”以及它们任何变形,意图在于覆盖不排他的包含。例如包含了一系列步骤或单元的过程、方法、系统、产品或设备没有限定于已列出的步骤或单元,而是可选地还包括没有列出的步骤或单元,或可选地还包括对于这些过程、方法、产品或设备固有的其他步骤或单元。
对本发明实施例进行进一步详细说明之前,对本发明实施例中涉及的名词和术语进行说明,本发明实施例中涉及的名词和术语适用于如下的解释。
1)PUCCH格式。
实际应用中,PUCCH用来承载上行控制信息,即UCI。UCI可以包括HARQ反馈信息,SR信息,以及信道状态信息(Channel state information,CSI)。
PUCCH上承载的UCI具有多种格式。参考表1所示,PUCCH格式0和PUCCH格式1均可以承载1比特或者2比特UCI信息。不同的是,PUCCH格式0最多可以占用2个时域符号,而PUCCH格式1可以占用4-14个时域符号。
表1
PUCCH格式 时域符号数量 承载UCI比特数量 物理资源块数量
0 1–2 ≤2 1
1 4–14 ≤2 1
2 1–2 >2 1-16
3 4–14 >2 1-16
4 4–14 >2 1
实际应用中,PUCCH格式0和PUCCH格式1在频域使用循环移位序列。其中,承载在PUCCH格式0中的UCI,是通过选择的循环移位偏移量(m cs)来隐式指示的。
具体地,当终端设备采用PUCCH格式0传输HARQ反馈信息时,可以根据网络设备的指示信息,确定传输使用的初始序列。同时,终端设备可以根据HARQ反馈信息的具体内容,确定循环移位偏移量(m cs)。这样,终端设备可以在确定的初始序列的基础上叠加上述m cs,得到最终的传输序列。对应的,网络设备根据接收到的传输序列可以确定出终端设备使用的m cs。进一步,网络设备可以根据HARQ反馈信息与循环移位偏移量之间的对应关系,确定出m cs对应的HARQ反馈信息的具体内容。
这里,HARQ反馈信息与循环移位偏移量之间的对应关系,可以参考表2和表3所示。其中,表2示出了通过PUCCH格式0传输1比特HARQ反馈信息时,HARQ反馈信息与循环移位偏移量之间的对应关系。表3示出了通过PUCCH格式0传输2比特HARQ反馈信息时,HARQ反馈信息与循环移位偏移量之间的对应关系。
表2
HARQ反馈信息 0 1
循环移位偏移量 m CS=0 m CS=6
表3
HARQ反馈信息 {0,0} {0,1} {1,1} {1,0}
循环移位偏移量 m CS=0 m CS=3 m CS=6 m CS=9
当终端设备采用PUCCH格式0传输SR信息时,若SR为正(positive),也就是说终端设备有上行SR,则终端设备使用m CS=0确定PUCCH的传输序列。若SR为负(negative),也就是说终端设备无上行SR,则终端设备不传输PUCCH。
另外,承载在PUCCH格式1上的UCI,先被调制成二进制相移键控(Binary Phase Shift Keying,BPSK)或正交相移键控(Quadrature Phase Shift Keying,QPSK)调制符号d(0),然后乘以基序列映射到频域的12个子载波上,在时域上使用叠加正交码(orthogonal cover code,OCC)进行扩展。
当终端设备采用PUCCH格式1传输HARQ反馈信息时,可以将1比特或者2比特HARQ反馈信息对应的调制符号d(0)乘到循环移位序列进行传输。
当终端设备使用PUCCH格式1传输SR信息时,若SR为positive,则传输PUCCH。若SR为negative,则终端设备不传输PUCCH。
2)上行控制信息复用
NR系统在上行传输上不支持多个PUCCH同时传输UCI,当多个PUCCH的时域资源发生重叠时,需要进行上行控制信息复用。目前,Release 15(R15)中定了如下复用规则:
规则1:在承载SR信息的PUCCH1,和承载HARQ反馈信息的PUCCH2均采用PUCCH格式0的情况下:
若SR信息为negative,则终端设备通过PUCCH2传输HARQ反馈信息;
若SR信息为positive,则终端设备在PUCCH2所在的物理资源块(Physical Resource Block,PRB)内传输一个PUCCH3。其中,PUCCH3使用的循环移位偏移量(m cs),可以根据表4或表5所示的复用场景下HARQ反馈信息与循环移位偏移量之间的对应关系确定。
其中,表4示出了通过PUCCH格式0,复用传输1比特HARQ反馈信息和SR信息时,HARQ反馈信息与循环移位偏移量之间的对应关系。表5示出了通过PUCCH格式0,复用传输2比特HARQ反馈信息时和SR信息时,HARQ反馈信息与循环移位偏移量之间的对应关系。
表4
HARQ反馈信息 0 1
循环移位偏移量 m CS=3 m CS=9
表5
HARQ反馈信息 {0,0} {0,1} {1,1} {1,0}
循环移位偏移量 m CS=1 m CS=4 m CS=7 m CS=10
值得注意的是,复用场景下HARQ反馈信息对应的循环移位偏移量,与单独传输HARQ反馈信息时使用的循环移位偏移(表2、3所示)不同。
规则2:在承载SR信息的PUCCH1采用PUCCH格式0,承载HARQ反馈信息的PUCCH2采用PUCCH格式1的情况下,终端设备仅通过PUCCH2传输HARQ反馈信息,不传输SR信息。
规则3:在承载SR信息PUCCH1和承载HARQ反馈信息的PUCCH2,均采用PUCCH格式1的情况下:
若SR为positive,则终端设备通过PUCCH1传输HARQ反馈信息。
若SR为negative,则终端设备通过PUCCH2传输HARQ反馈信息。
规则4:当承载SR信息的PUCCH1采用PUCCH格式1,承载HARQ反馈信息的PUCCH2采用PUCCH格式0时,这种情况不支持。即传输1比特SR信息的PUCCH1占用的时域资源不应该比传输1或2比特HARQ反馈信息的PUCCH2占用的时延资源还短。
NR系统的R16引入了UCI优先级处策略,终端设备会优先保障高优先级UCI的传输。然而,丢弃低优先级UCI会对上行业务造成不利影响。为此,在R17版本讨论中,支持将时域资源重叠的不同优先级UCI进行复用传输。然而,如何对不同优先级的UCI进行复用传输,目前还没有明确的方法。
基于此,本申请实施例提供了一种上行控制信息传输方法,具体地,终端设备在确定承载高优先级 信息(即第一信息)的第一PUCCH的时域资源,与承载低优先级信息(即第二信息)的第二PUCCH的时域资源发生重叠后,终端设备或网络设备可以基于第一PUCCH包括的时域符号的数量与第二PUCCH包括的时域符号的数量之间的关系,来确定第三PUCCH,并通过第三PUCCH发送或接收第一信息和第二信息中的至少一个信息。也就是说,当不同优先级的上行控制信息在时域上发生重叠的时候,可以选择合适的第三PUCCH对不同优先级的上行控制信息进行复用传输,提高数据传输效率。

应理解,本文中术语“系统”和“网络”在本文中可以互换使用。本文中的“第一信息”和“高优先级信息”可以互换使用,“第二信息”和“低优先级信息”可以互换使用。
下面将结合本申请实施例中的附图,对本申请实施例中的技术方案进行清楚、完整地描述。
本申请实施例提供一种上行控制信息传输方法,可以应用于图1所示的通信系统架构中。具体地,参考图2所示的流程示意图,本申请实施例提供的上行控制信息传输可以包括以下步骤:
步骤210、在具有上行SR的情况下,终端设备通过第三PUCCH,传输第一信息和第二信息中的至少一个信息。
步骤220、网络设备通过第三PUCCH接收第一信息和第二信息中的至少一个信息。
这里,终端设备可以通过第三PUCCH,向网络设备发送第一信息和第二信息中的至少一个信息。
对应的,网络设备通过第三PUCCH,接收终端设备发送的第一信息和第二信息中的至少一个信息。
在本申请实施例中,第三PUCCH基于第一PUCCH包括的时域符号的数量与第二PUCCH包括的时域符号的数量之间的关系确定;其中,第一信息和第二信息中的一个信息为SR信息,第一PUCCH与第二PUCCH重叠;第一PUCCH为预配置承载第一信息的PUCCH,第二PUCCH为预配置承载第二信息的PUCCH;第二信息的优先级低于第一信息的优先级。
这里,第一PUCCH与第二PUCCH重叠,具体是指,第一PUCCH的时域资源和第二PUCCH的时域资源重叠。这里,时域资源重叠可以是指第一PUCCH的时域资源与第二PUCCH的时域资源部分重叠,也可以是指第一PUCCH的时域资源与第二PUCCH的时域资源完全重叠,本申请对此不做限定。
本申请实施例中,网络设备可以为每个UCI预先配置对应的PUCCH资源,并通过信令向终端设备指示每个UCI对应的PUCCH资源。这里的信令可以是高层信令也可以是物理层信令,高层信令可以为无线资源控制(Radio Resource Control,RRC)信令或媒体接入控制(Medium Access Control,MAC)控制元素(Control Element,CE),物理层信令可以是下行控制信息(Downlink Control Information,DCI)。本申请实施例对此不做限定。
也就是说,终端设备可以接收网络设备发送的信令,通过信令中包含的配置信息来确定第一信息对应的第一PUCCH,以及第二信息对应的第二PUCCH。
本申请实施例中,网络设备还可以为每个UCI配置其对应的优先级,并通过信令向终端设备指示每个UCI对应的优先级。为UCI配置PUCCH资源的信令和配置优先级的信令可以为同一信令,也可以为不同的信令,本申请实施例对此不做限定。
本申请实施例中,优先级可以理解为是信息的传输优先级,信息的优先级越高,那么该信息对传输 的性能要求也越高。这里的性能要求,具体是指对传输可靠性的要求,或者对时延的要求,本申请实施例对此不做限定。
具体地,网络设备可以基于对信息传输性能的要求,为每个UCI赋予不同的优先级。示例性的,若第一信息对时延敏感,网络设备可以为第一信息赋予高优先级,若第二信息对时延不敏感,则可以为第二信息赋予低优先级。
在本申请实施例中,第一信息和第二信息不同,第一信息和第二信息中的一个信息可以为SR信息,第一信息和第二信息中的一个信息可以为HARQ反馈信息。
具体地,第一信息为SR信息,第二信息为HARQ反馈信息;
或者,
第一信息为HARQ反馈信息,第二信息为SR信息。
另外,本申请实施例中,终端设备不期待一个第一PUCCH的时域资源与多个第二PUCCH的时域资源重叠的情况发生,其中,多个第二PUCCH之间的时域资源互不重叠。本申请实施例中的第一PUCCH和第二PUCCH的数量均为一个。也就是说,本申请实施例提到的第一PUCCH的时域资源与第二PUCCH的时域资源重叠,具体是指,一个第一PUCCH的时域资源和一个第二PUCCH的时域资源重叠。
可以理解的是,在确定承载高优先级信息(即第一信息)的第一PUCCH的时域资源,与承载低优先级信息(即第二信息)的第二PUCCH的时域资源发生重叠后,终端设备或网络设备可以根据第一PUCCH包含的时域符号数量与第二PUCCH包含的时域符号数量之间的关系,来确定第三PUCCH,并通过第三PUCCH发送或接收第一信息和第二信息中的至少一个信息。也就是说,当不同优先级的上行控制信息在时域上发生重叠的时候,可以选择合适的第三PUCCH对不同优先级的上行控制信息进行复用传输,提高数据传输效率。
实际应用中,终端设备并不是一直有上行SR,即终端设备并不是一直有发送SR信息的需求。当终端设备具有上行SR,则认为SR为正(即positive)。当终端设备不具有上行SR,则认为SR为负(即negative)。
在本申请实施例中,在具有上行SR,即SR为positive的情况下,终端设备可以根据第一PUCCH包括的时域符号的数量与第二PUCCH包括的时域符号的数量之间的关系,来确定第三PUCCH。
另外,在终端设备不具有上行SR,即SR为negative的情况下,终端设备可以仅传输其他信息。
示例性的,第一PUCCH预配置为承载SR信息,第二PUCCH预配置为承载HARQ反馈信息;不论SR信息的优先级高于HARQ反馈信息,还是低于HARQ反馈信息,终端设备均通过第二PUCCH传输HARQ反馈信息。
对应的,网络设备在确定第一PUCCH和第二PUCCH在时域上重叠后,可以基于第一PUCCH包括的时域符号的数量,以及第二PUCCH包括的时域符号的数量来确定第三PUCCH,在第三PUCCH上接收第一消息和/或第二消息。
在本申请实施例中,在确定不同优先级信息的PUCCH时域资源发生重叠之后,可以根据第一PUCCH包括的时域符号的数量,以及第二PUCCH包括的时域符号的数量之间的关系确定第三PUCCH,进一步通过第三PUCCH传输第一信息和第二信息中的至少一个信息。
其中,时域符号可以是正交频分复用(Orthogonal Frequency Division Multiplexing,OFDM)符号,也可以是单载波频分复用(Single Carrier Frequency Division Multiplexing,SC-FDM)符号。本申请实施例对此不做限定。
下面,详细介绍如何基于第一PUCCH包括的时域符号的数量,以及第二PUCCH包括的时域符号的数量之间的关系,来确定第三PUCCH。
在本申请一实施例中,若第二PUCCH包括的时域符号的数量大于或等于第一PUCCH包括的时域符号的数量,则第三PUCCH的传输资源与第二PUCCH的传输资源相同。
这里,第三PUCCH可以用于传输第一信息和第二信息。
也就是说,当预配置的承载低优先级信息的第二PUCCH包括的时域符号的数量,大于或等于预配置的承载高优先级信息的第一PUCCH包括的时域符号的数量时,终端设备可以使用与第二PUCCH相同的传输资源,来对第一信息和第二信息进行复用传输。即,使用第二PUCCH相同的传输资源传输第一信息和第二信息。
需要说明的是,本申请实施例中的第一PUCCH的PUCCH格式与第二PUCCH的PUCCH格式相同。具体地,第一PUCCH与第二PUCCH的PUCCH格式均为PUCCH格式0或PUCCH格式1。
可以理解的是,PUCCH格式0和PUCCH格式1均在频域资源固定占用1个PRB,其传输可靠性主要受到时域符号数量(1或2)的影响。时域符号数量越多,提供PUCCH传输的时间就越长,有助 于提升覆盖距离,从而传输的可靠性越高。基于此,当低优先级的第二信息对应的第二PUCCH包括的时域符号的数量,大于或等于高优先级的第一信息对应的第一PUCCH包括的时域符号的数量时,使用与承载低优先级信息的第二PUCCH相同的时频资源同时传输第一信息和第二信息,可以保证高优先级信息的传输可靠性。
在本申请实施例中,第三PUCCH的传输资源与第二PUCCH的传输资源相同可以包括多种方式,下面详细介绍其中的两种方式。
在第一种可能的实现方式中,第三PUCCH的传输资源与第二PUCCH的传输资源相同,可以是指第三PUCCH占用的时域资源与第二PUCCH占用的时域资源相同,并且第三PUCCH占用的频域资源与第二PUCCH占用频域资源相同。
具体地,当第一信息为SR信息,第二信息为HARQ反馈信息,且第一PUCCH与第二PUCCH的PUCCH格式均为PUCCH格式0的情况下,第三PUCCH占用的时域资源与第二PUCCH占用的时域资源相同,且第三PUCCH占用的频域资源与第二PUCCH占用的频域资源相同。
也就是说,当高优先级信息为SR信息,低优先级信息为HARQ反馈信息,并且承载SR信息和HARQ反馈信息的PUCCH的格式均为PUCCH格式0时,终端设备可以使用第二PUCCH的时域资源和频域资源,对SR信息和HARQ反馈信息进行复用传输。
这里,第三PUCCH传输序列的循环移位偏移量可以根据表4或表5确定。具体地,终端设备可以从表4或表5中选择与HARQ反馈信息的具体内容对应的循环移位偏移量,确定第三PUCCH传输序列。
在第二种可能的实现方式中,第三PUCCH的传输资源与第二PUCCH的传输资源相同,可以是指第三PUCCH占用的时域资源与第二PUCCH占用的时域资源相同,第三PUCCH占用的频域资源与第二PUCCH占用的频域资源相同,且第三PUCCH占用的序列资源与第二PUCCH占用的序列资源相同。
具体地,在第一信息为HARQ反馈信息,第二信息为SR信息,且第一PUCCH和第二PUCCH的PUCCH格式均为PUCCH格式1的情况下,第三PUCCH占用的时域资源与第二PUCCH占用的时域资源相同,第三PUCCH占用的频域资源与第二PUCCH占用的频域资源相同,以及第三PUCCH占用的序列资源与第二PUCCH占用的序列资源相同。
也就是说,当高优先级信息为HARQ反馈信息,低优先级信息为SR信息,并且承载HARQ反馈信息和SR信息的PUCCH的格式均为PUCCH格式1时,终端设备可以使用第二PUCCH的时域资源、频域资源和序列资源,传输SR信息和HARQ反馈信息。
这里,第三PUCCH的传输序列基于HARQ反馈信息对应的调制符号与初始序列相乘得到。
在本申请另一实施例中,若第二PUCCH包括的时域符号的数量,小于第一PUCCH包括的时域符号的数量,则第三PUCCH为第一PUCCH。
这里,第三PUCCH用于传输第一信息。
也就是说,当预配置的承载低优先级信息的第二PUCCH包括的时域符号的数量,小于预配置的承载高优先级信息的第一PUCCH包括的时域符号的数量,则丢弃低优先级信息,通过承载高优先级信息的第一PUCCH,传输具有高优先级的第一信息。
需要说明的是,本申请实施例中的第一PUCCH的PUCCH格式与第二PUCCH的PUCCH格式相同。具体地,第一PUCCH与第二PUCCH的PUCCH格式均为PUCCH格式0或PUCCH格式1。
可以理解的是,PUCCH格式0和PUCCH格式1均在频域资源固定占用1个PRB,其传输可靠性主要受到时域符号数量(1或2)的影响。时域符号的数量越多,提供PUCCH传输的时间就越长,有助于提升覆盖距离,从而传输的可靠性越高。
基于此,当具有低优先级的第二信息对应的第二PUCCH包括的时域符号的数量,小于高优先级的第一信息对应的第一PUCCH包括的时域符号的数量时,仍强行进行复用传输可能会对高优先级信息的传输可靠性造成影响。因此,当第二PUCCH包括的时域符号的数量,小于第一PUCCH包括的时域符号的数量时,可以直接将低优先级的第二信息丢弃,仅通过第一PUCCH传输高优先级的第一信息,从而保证高优先级信息传输的可靠性。
下面结合图3所示的流程示意图,对本申请实施例提供的上行控制信息传输方法进行描述。
参考图3所示,本申请实施例提供的上行控制信息传输方法,可以包括以下步骤:
步骤310、确定预配置承载第一信息的第一PUCCH的时域资源,与预配置承载第二信息的第二PUCCH的时域资源重叠。
这里,第二信息的优先级低于第一信息。
在本申请一实施例中,第一信息为SR信息,第二信息为HARQ反馈信息,且第一PUCCH和第二PUCCH均采用PUCCH格式0。
在本申请另一实施例中,第一信息为HARQ反馈信息,第二信息为SR信息,且第一PUCCH和第二PUCCH均采用PUCCH格式1。
步骤320、判断是否具有上行SR。
终端设备可以判断当前是否有上行SR发送,即判断SR为positive还是negative。
若终端设备无上行SR发送(即SR为negative),则执行步骤330。若终端设备具有上行SR发送(即SR为positive),则执行步骤340。
步骤330、若终端设备无上行SR发送,则终端设备通过预配置承载HARQ反馈信息的PUCCH,发送HARQ反馈信息。
可以理解的是,在终端设备无上行SR发送的情况下,终端设备可以直接发送HARQ反馈信息。
具体地,在步骤310提供的第一个实施例中,当终端设备确定不具有上行SR后,可以通过第二PUCCH发送HARQ反馈信息。在步骤310提供的第二个实施例中,当终端设备确定不具有上行SR后,可以通过第一PUCCH发送HARQ反馈信息。
值得注意的是,该分支步骤的执行方式与R15规定的处理方式相同。
步骤340、若终端设备有上行SR发送,则判断第二PUCCH包括的时域符号的数量是否小于第一PUCCH包括的时域符号的数量。
具体地,若第二PUCCH包括的时域符号的数量,小于第一PUCCH包括的时域符号的数量,则执行步骤350。若第二PUCCH包括的时域符号的数量,不小于第一PUCCH包括的时域符号的数量,则执行步骤360。
步骤350、若第二PUCCH包括的时域符号的数量,小于第一PUCCH包括的时域符号的数量,则通过第一PUCCH传输第一信息,丢弃第二信息。
可以理解的是,当第二PUCCH包括的时域符号的数量小于第一PUCCH包括的时域符号的数量,可以确定承载低优先级信息(即第二信息)的第二PUCCH传输可靠性较低,若复用传输则无法保证高优先级信息(即第一信息)的传输可靠性。因此,在第二PUCCH包括的时域符号的数量小于第一PUCCH包括的时域符号的数量的情况下,可以丢弃低优先级信息,仅通过第一PUCCH传输高优先级信息。
值得注意的是,该分支步骤的执行方式与R16规定的处理方式相同。
步骤360、第二PUCCH包括的时域符号的数量,不小于第一PUCCH包括的时域符号的数量,则通过第二PUCCH的传输资源,复用传输第一信息和第二信息。
可以理解的是,当第二PUCCH包括的时域符号的数量大于或等于第一PUCCH包括的时域符号的数量,可以确定承载低优先级信息(即第二信息)的第二PUCCH传输可靠性较高,通过第二PUCCH的传输资源来复用传输第一信息和第二信息,可以保证高优先级信息的性能要求。
具体地,在步骤310提供的第一个实施例中,当终端设备确定第二PUCCH包括的时域符号的数量大于或等于第一PUCCH包括的时域符号的数量时,终端设备可以使用与第二PUCCH相同的时域资源和频域资源传输一个采用PUCCH格式0的第三PUCCH,第三PUCCH的循环移位偏移可以通过表4或5所示的对应关系确定。
在步骤310提供的第二个实施例中,当终端设备确定第二PUCCH的包括时域符号的数量大于或等于第一PUCCH包括的时域符号的数量时,终端设备可以使用第二PUCCH的时域资源、频域资源、以及序列资源传输第三PUCCH,第三PUCCH能够承载第一信息和第二信息。其中,终端设备可以根据HARQ反馈信息对应的调制符号与序列相乘得到第三PUCCH。
值得注意的是,该分支步骤的执行方式与R15规定的处理方式相同。
综上所述,本申请实施例可以通过时域符号作为复用传输的判决条件,保证复用传输时高优先级信息的可靠性。并且,终端设备的具体行为与现有R15、R16定义的行为相同,不引入新的处理复杂度。
本申请实施例还提供一种上行控制信息传输方法,参考图4所示所示的流程示意图,所述上行控制信息传输方法可以
步骤410、在终端设备具有上行SR,且预配置承载SR信息的第一PUCCH,与多个预配置承载HARQ反馈信息的第二PUCCH重叠的情况下,终端设备传输第一PUCCH和多个第二PUCCH中承载第一信息的PUCCH。
步骤420、网络设备在预配置承载SR信息的第一PUCCH,与多个预配置承载HARQ反馈信息的第二PUCCH重叠的情况下,接收第一PUCCH,或者多个第二PUCCH。
这里,SR信息和HARQ反馈信息的优先级不同;第一信息为SR信息和HARQ反馈信息的优先级高的信息。
另外,需要说明的是,上述多个第二PUCCH之间互不重叠,多个PUCCH承载的多个HARQ反馈信息的优先级均相同。
在本申请实施例中,终端设备不期待一个第一PUCCH的时域资源与多个第二PUCCH的时域资源重叠的情况发生。然而,实际应用中不可避免发生第一PUCCH和多个第二PUCCH的时域资源重叠的情况。因此,本申请实施例中,当一个第一PUCCH与多个第二PUCCH的时域资源重叠时,终端设备可以优先发送承载具有高优先级的第一信息的PUCCH,丢弃承载低优先级的信息的PUCCH。如此,保证高优先级信息的传输可靠性。
对应的,网络设备在确定第一PUCCH与多个第二PUCCH的时域资源重叠后,因为网络设备并不能确定终端设备当前是否具有上行SR,因此,网络设备可以在第一PUCCH以及多个第二PUCCH上同时监听上行控制信息。也就是说,网络设备可以接收第一PUCCH承载的SR信息,或者多个第二PUCCH承载的HARQ反馈信息。
在本申请实施例中,第一PUCCH的PUCCH格式与多个第二PUCCH的PUCCH格式相同。具体地,第一PUCCH与第二PUCCH的PUCCH格式均PUCCH格式0或PUCCH格式1。
在本申请一实施例中,若SR信息的优先级高于多个HARQ反馈信息的优先级,则终端设备传输第一PUCCH。这里,第一PUCCH和多个第二PUCCH的PUCCH格式均为PUCCH格式0。
可以理解的是,在终端设备具有上行SR的情况下,当SR信息的优先级高于多个HARQ反馈信息的优先级,则终端设备丢弃多个第二PUCCH,以及多个第二PUCCH承载的多个HARQ反馈信息,仅通过第一PUCCH发送具有高优先级的SR信息。如此,保证第一PUCCH中承载的SR信息的传输可靠性。
对应的,由于网络设备并不能确定当前终端设备是否具有上SR,因此网络设备在确定了SR信息的优先级高于多个HARQ反馈信息的优先级后,网络设备可以同时监听第一PUCCH和多个第二PUCCH,通过第一PUCCH接收SR信息,或者多个第二PUCCH接收HARQ反馈信息。
在本申请另一实施例中,若SR信息的优先级低于HARQ反馈信息的优先级,则终端设备传输多个第二PUCCH。这里,第一PUCCH和多个第二PUCCH的PUCCH格式均为PUCCH格式1。
可以理解的是,当多个HARQ反馈信息的优先级高于SR信息的优先级,则终端设备可以丢弃第一PUCCH以及第一PUCCH承载的SR信息,通过多个第二PUCCH发送具有高优先级的HARQ反馈信息。如此,保证多个第二PUCCH中承载的HARQ反馈信息的传输可靠性。
对应的,在网络设备确定了SR信息的优先级低于HARQ反馈信息的优先级后,网络设备可以确定终端设备会丢弃低优先级的SR信息,仅发送承载高优先级的HARQ反馈信息的多个第二PUCCH。因此,网络设备可以仅监听多个第二PUCCH,接收多个第二PUCCH承载的HARQ反馈信息。
另外,在本申请一实施例中,在终端设备具有上行SR且预配置承载SR信息的第一PUCCH,与一个预配置承载HARQ反馈信息的第二PUCCH重叠的情况下,终端可以在满足约束条件时,通过第三PUCCH传输SR和HARQ反馈信息。
对应的,网络设备可以在预配置承载SR信息的第一PUCCH,与一个预配置承载HARQ反馈信息的第二PUCCH重叠的情况下,且在满足约束条件时,通过第三PUCCH接收SR和HARQ反馈信息
其中,SR信息和HARQ反馈信息的优先级不同,约束条件包括:第一PUCCH包括的时域符号的数量与第二PUCCH包括的时域符号的数量之间关系满足第一预设条件。
可以理解的是,在确定一个第一PUCCH和一个第二PUCCH在时域资源上发生重叠后,可以判断承载SR信息的第一PUCCH包括的时域符号的数量,与承载HARQ反馈信息的第二PUCCH包括的时域符号的数量是否满足第一预设条件,若满足第一预设条件,则通过第三PUCCH传输SR和HARQ反馈信息。
具体地,在本申请一实施例中,当SR信息的优先级高于HARQ反馈信息的优先级,且第一PUCCH和第二PUCCH的PUCCH格式均为PUCCH格式0的情况下,上述第一预设条件可以是,第二PUCCH包括的时域符号的数量,大于或等于第一PUCCH包括的时域符号的数量。
也就是说,当承载HARQ反馈信息(即低优先级信息)的第二PUCCH包括的时域符号的数量,大于或等于承载SR信息(即高优先级信息)的第一PUCCH包括的时域符号的数量时,通过第三PUCCH复用传输SR和HARQ反馈信息。
这里的第三PUCCH的时域资源与第二PUCCH的时域资源相同,且第三PUCCH的频域资源与第二PUCCH的频域资源相同。也就是说,当第二PUCCH包括的时域符号的数量,大于或等于第一PUCCH包括的时域符号的数量时,使用第二PUCCH的时域资源和频域资源复用传输SR和HARQ反馈信息。其中,第三PUCCH的传输序列的循环移位偏移量可以根据表4或表5确定。
可以理解的是,在本申请实施例中第二PUCCH承载具有低优先级的HARQ反馈信息,第一PUCCH承载具有高优先级的SR信息。当第二PUCCH包括的时域符号的数量,大于或等于第一PUCCH包括的时域符号的数量,则可以利用第二PUCCH的时域资源和频域资源复用传输SR和HARQ反馈信息, 不仅能够保障高优先级的SR信息的传输可靠性,还可以复用传输低优先级的HAQR反馈信息,有效提高了数据传输效率。
在本申请另一实施例中,当SR信息的优先级低于HARQ反馈信息的优先级,且第一PUCCH和第二PUCCH均采用PUCCH格式1时,上述第一预设条件可以是,第一PUCCH包括的时域符号的数量,大于或等于第二PUCCH包括的时域符号的数量。
也就是说,当承载SR反馈信息(即低优先级信息)的第一PUCCH包括的时域符号的数量,大于或等于承载HARQ反馈信息(即高优先级信息)的第二PUCCH包括的时域符号的数量时,通过第三PUCCH复用传输SR和HARQ反馈信息。
这里,第三PUCCH的时域资源与第一PUCCH的时域资源相同,第三PUCCH的频域资源与第一PUCCH的频域资源相同,并且第三PUCCH的序列资源与第一PUCCH的序列资源相同。
可以理解的是,在本申请实施例中第一PUCCH承载具有低优先级的SR信息,第二PUCCH承载具有高优先级的HARQ反馈信息。当第一PUCCH包括的时域符号数量,大于或等于第二PUCCH包括的时域符号数量,则利用第一PUCCH的时域资源、频域资源以及序列资源复用传输SR和HARQ反馈信息,不仅能够保障高优先级的HARQ信息的传输可靠性,还可以复用传输低优先级的SR信息,有效提高了数据传输效率。
下面结合具体应用场景对本申请实施例提供的上行控制信息传输方法进行详细阐述。
实施例一
参考图5所示的一种上行控制信息复用传输的场景示意图一,在本实施例中,第一PUCCH和第二PUCCH在时域上发生重叠。其中,第一PUCCH和第二PUCCH均采用PUCCH格式0传输信息,且第一PUCCH承载SR信息,第二PUCCH承载为HARQ反馈信息。SR信息的优先级高于HARQ反馈信息的优先级。
在一种可能的实现方式中,当SR信息为negative时,终端设备通过第二PUCCH传输HARQ反馈信息。该实现方式中终端设备的处理方式与R15相同。
在另一种可能的实现方式中,当SR信息为positive时,终端设备可以基于第一PUCCH的时域符号的数量与第二PUCCH的时域符号的数量之间的关系,确定复用传输的方式。
具体地,若第二PUCCH包括的时域符号数量,大于或等于第一PUCCH包括的时域符号数量,则将SR信息和HARQ反馈信息复用传输。也就是说,承载低优先级信息的第二PUCCH包括的符号数量大于或等于,承载高优先级信息的第一PUCCH包括的符号数量,则将低优先级信息和高优先级信息进行复用传输。
进一步地,将SR信息和HARQ反馈信息复用传输,可以是使用第二PUCCH的时域资源和频域资源传输第三PUCCH,该第三PUCCH中可以承载SR信息和HARQ反馈信息,第三PUCCH的格式仍然是PUCCH格式0。
这里,在第三PUCCH中承载SR信息和HARQ反馈信息,具体可以是终端设备根据HARQ反馈信息的具体内容,选择目标循环移位偏移量;进而,根据目标循环偏移量和基序列,得到在第三PUCCH对应的传输序列。具体地,终端设备可以根据表4或表5所示的复用场景下HARQ反馈信息与循环移位偏移量之间的对应关系,确定上述HARQ反馈信息对应的目标循环移位偏移量。
可以理解的是,PUCCH格式0在频域资源是上固定占用1个PRB,其传输可靠性主要受到时域符号数量(1或2)的影响。时域符号数量越多,提供PUCCH传输的时间就越长,有助于提升覆盖距离,从而传输的可靠性越高。当低优先级的HARQ反馈信息对应的第二PUCCH包括的时域符号数量,大于或等于高优先级的SR信息对应的第一PUCCH格式包括的时域符号数量时,使用与承载低优先HARQ反馈信息的第二PUCCH相同的时频资源,但循环偏移量不同的第三PUCCH传输SR信息和HARQ反馈信息时,仍然可以保证SR信息的传输可靠性。
值得注意的是,该实现方式中终端设备的处理方式与R15相同。
另外,若第二PUCCH包括的时域符号的数量,大于或等于第一PUCCH包括的时域符号的数量,则终端设备通过第一PUCCH传输SR信息,并丢弃HARQ反馈信息。
也就是说,承载低优先级信息的第二PUCCH包括的时域符号的数量小于,承载高优先级信息的第一PUCCH包括的时域符号的数量,则丢弃低优先级的信息,仅传输高优先级的信息。如此,保障高优先级信息的可靠性。
值得注意的是,该实现方式中终端设备的处理方式与R16相同。
由此可见,本申请实施例引入时域符号的判断条件,保证复用传输时高优先级UCI的可靠性。另外,本申请实施例中终端设备的具体行为与现有R15、R16相同,不引入新的处理复杂度。
在本实施例中,上面的示例仅说明的一个第一PUCCH与一个第二PUCCH时域资源重叠时方式。 终端设备并不期待一个第一PUCCH的时域资源与多个第二PUCCH的时域资源重叠,其中多个第二PUCCH之间时域资源互不重叠。
这里,低优先级的HARQ反馈信息对传输时延不敏感,网络设备可以通过合理调度避免第一PUCCH与多个第二PUCCH时域资源重叠的情况发生。若没有进行调度避免,则可以通过以下方式进行处理。
具体地,参考图6所示,若一个第一PUCCH(例如图6所示的PUCCH A)的时域资源与多个第二PUCCH的时域资源重叠,且多个第二PUCCH(例如图6所示的PUCCH X和PUCCH Y)之间时域资源互不重叠时,终端设备可以通过第一PUCCH(即图6所示的PUCCH A)传输高优先级的SR信息,并丢弃多个第二PUCCH(即图6所示的PUCCH X和PUCCH Y)中承载的所有低优先级的HARQ反馈信息。
值得注意的是,该实现方式中终端设备的处理方式与R16中规定的处理机制相同。
实施例二
参考图7所示的一种上行控制信息复用传输的场景示意图一,在本实施例中,第一PUCCH和第二PUCCH在时域上发生重叠。其中,第一PUCCH和第二PUCCH均采用PUCCH格式1传输信息,且第一PUCCH用于承载HARQ反馈信息,第二PUCCH用于承载SR信息,HARQ反馈信息的优先级高于SR信息的优先级。
在一种可能的实现方式中,当SR信息为negative时,终端设备通过第一PUCCH传输HARQ反馈信息。该实现方式中终端设备的处理方式与R15相同。
在另一种可能的实现方式中,当SR信息为positive时,终端设备可以基于第一PUCCH包括的时域符号的数量与第二PUCCH包括的时域符号的数量之间的关系,确定复用传输的方式。
具体地,若第二PUCCH包括的时域符号的数量,大于或等于第一PUCCH包括的时域符号的数量,则将SR信息和HARQ反馈信息复用传输。也就是说,承载低优先级信息的第二PUCCH包括的时域符号的数量大于或等于,承载高优先级信息的第一PUCCH包括的时域符号的数量,则将低优先级信息和高优先级信息进行复用传输。
进一步地,将SR信息和HARQ反馈信息复用传输,可以是使用第二PUCCH的时域资源、频域资源以及序列资源传输第三PUCCH,在第三PUCCH中承载SR信息和HARQ反馈信息。其中,第三PUCCH的格式仍然是PUCCH格式1。
这里,在第三PUCCH中承载SR信息和HARQ反馈信息,具体可以是终端设备可以将HARQ反馈信息对应的调制符号乘到循环移位序列上进行传输。
可以理解的是,PUCCH格式1在频域资源是上固定占用1个PRB,其传输可靠性主要受到时域符号数量(1或2)的影响。时域符号数量越多,提供PUCCH传输的时间就越长,有助于提升覆盖距离,从而传输的可靠性越高。当低优先级的SR反馈信息对应的第二PUCCH包括的时域符号数量,大于或等于高优先级的HARQ反馈信息对应的第一PUCCH格式包括的时域符号数量时,使用预配置用于传输低优先级SR信息的第二PUCCH传输高优先级的HARQ反馈信息,仍然可以保证HARQ反馈信息的传输可靠性。
值得注意的是,该实现方式中终端设备的处理方式与R15相同。
另外,若第二PUCCH包括的时域符号的数量,大于或等于第一PUCCH包括的时域符号的数量,则终端设备通过第一PUCCH传输高优先级的HARQ反馈信息,并丢弃低优先级的SR信息。
也就是说,承载低优先级信息的第二PUCCH包括的时域符号的数量小于,承载高优先级信息的第一PUCCH包括的时域符号的数量,则丢弃低优先级的信息,仅传输高优先级的信息。如此,保障高优先级信息的可靠性。
值得注意的是,该实现方式中终端设备的处理方式与R16相同。
由此可见,本申请实施例引入时域符号的判断条件,保证复用传输时高优先级UCI的可靠性。另外,本申请实施例中终端设备的具体行为与现有R15、R16相同,不引入新的处理复杂度。
在本实施例中,上面的示例仅说明的一个第一PUCCH与一个第二PUCCH时域资源重叠时方式。终端设备并不期待一个第一PUCCH的时域资源与多个第二PUCCH的时域资源重叠,其中多个第二PUCCH之间时域资源互不重叠。
这里,低优先级的HARQ反馈信息对传输时延不敏感,网络设备可以通过合理调度避免第一PUCCH与多个第二PUCCH时域资源重叠的情况发生。若没有进行调度避免,则可以通过以下方式进行处理。
具体地,参考图8所示,若一个第二PUCCH(例如图8所示的PUCCH A’)的时域资源与多个第一PUCCH的时域资源重叠,且多个第二PUCCH(例如图8所示的PUCCH X’和PUCCH Y’)之间时域资源互不重叠时,终端设备可以通过多个第二PUCCH(即图8所示的PUCCH X’和PUCCH Y’)传输高优先级的HARQ反馈信息,并丢弃第一PUCCH(即图8所示的PUCCH A’)中承载的低优先级的 SR信息。
综上所述,本申请实施例可以引入时域符号的判断条件,保证复用传输时高优先级信息的可靠性,还可以提高数据传输效率。并且,终端设备的具体行为与现有R15、R16相同,不引入新的处理复杂度。
