Description

一种控制信息发送、接收方法及装置
本申请要求在2017年6月15日提交中国专利局、申请号为201710454090.5、申请名称为“一种控制信息发送、接收方法及装置”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。
技术领域
本发明实施例涉及通信技术领域,尤其涉及一种控制信息发送、接收方法及装置。
背景技术
目前,对于用户设备(User Equipment,UE)要发送的上行控制信息都有与其对应的物理上行控制信道(Physical Uplink Control Channel,PUCCH)资源,例如对于混合自动重传请求应答(Hybrid Automatic Repeat reQuest ACK,HARQ-ACK),基站会分配HARQ-ACK对应的PUCCH资源,对于周期信道状态信息(Channel State Information,CSI),基站也会分配周期CSI对应的PUCCH资源,则无论UE是在一个上行子帧内发送多种上行控制信息还是在不同的上行子帧内发送不同的上行控制信息,UE都可以在为相应的上行控制信息分配的PUCCH资源上分别发送。
那么,如果UE发送多种上行控制信息,UE要对不同的PUCCH资源上发送的上行控制信息分别执行离散傅里叶变换(Discrete Fourier Transform,DFT),则UE在上行子帧发送的信号的峰值平均功率比(Peak to Average Power Ratio,PAPR)就会比较大,导致UE的功率效率很低。另一方面,在不同的PUCCH资源上发送的信号之间的互调干扰(Intermodulation Interference,IMD)也会导致上行控制信息的接收性能都较差。
发明内容
本发明实施例提供一种控制信息发送、接收方法及装置,用于提供一种确定传输PUCCH的资源的方式。
第一方面,提供一种控制信息发送方法,该方法可由终端设备执行。该方法包括:终端设备从第一上行控制信道和第二上行控制信道中确定目标上行控制信道。其中,第一上行控制信道对应第一上行控制信息,第二上行控制信道对应第二上行控制信息。终端设备在目标上行控制信道发送目标上行控制信息,目标上行控制信息包括第一上行控制信息和第二上行控制信息。
第二方面,提供一种控制信息接收方法,该方法可由网络设备执行,网络设备例如为基站。该方法包括:网络设备从第一上行控制信道和第二上行控制信道中确定目标上行控制信道。其中,第一上行控制信道对应第一上行控制信息,第二上行控制信道对应第二上行控制信息。网络设备在目标上行控制信道接收终端设备发送的目标上行控制信息,目标上行控制信息包括第一上行控制信息和第二上行控制信息。
第三方面,提供一种控制信道确定方法。该方法包括:终端设备从第一上行控制信道和第二上行控制信道中确定目标上行控制信道。其中,第一上行控制信道对应第一上行控制信息,第二上行控制信道对应第二上行控制信息。终端设备将目标上行控制信息映射到目标上行控制信道,目标上行控制信息包括第一上行控制信息和第二上行控制信息。
第四方面,提供一种控制信道确定方法。该方法包括:网络设备从第一上行控制信道和第二上行控制信道中确定目标上行控制信道。其中,第一上行控制信道对应第一上行控制信息,第二上行控制信道对应第二上行控制信息。网络设备在目标上行控制信道解码目标上行控制信息,目标上行控制信息包括第一上行控制信息和第二上行控制信息。
本发明实施例中,如果终端设备要传输两个上行控制信息,那么终端设备就从两个上行控制信息分别对应的上行控制信道中选择一个作为目标上行控制信道,并通过目标上行控制信道发送两个上行控制信息,例如上行控制信道为PUCCH,那么本发明实施例就是将多个上行控制信息放到一个PUCCH资源中发送,通过这种方式可以减小终端设备在上行子帧发送的信号的PAPR,提高终端设备的功率效率。另一方面,由于将多个上行控制信息通过一个目标上行控制信道发送,减小了信号之间的IMD,从而能够增强上行控制信息的接收性能。
在一个可能的设计中,终端设备从第一上行控制信道和第二上行控制信道中确定目标上行控制信道,包括:终端设备根据第一上行控制信道的容量和第二上行控制信道的容量从第一上行控制信道和第二上行控制信道中确定目标上行控制信道。相应的,网络设备从第一上行控制信道和第二上行控制信道中确定目标上行控制信道,包括:网络设备根据第一上行控制信道的容量和第二上行控制信道的容量从第一上行控制信道和第二上行控制信道中确定目标上行控制信道。其中,目标上行控制信道是第一上行控制信道和第二上行控制信道中容量较大的上行控制信道。
在本发明实施例中,终端设备可以采用多种不同的方式来从第一上行控制信道和第二上行控制信道中确定目标上行控制信道。其中一种方式为,终端设备根据上行控制信道的容量来确定目标上行控制信道。因为本发明实施例希望将第一上行控制信息和第二上行控制信息放到一个上行控制信道中发送,因此,目标上行控制信道的容量越大,能够承载的信息就越多,就越能保证第一上行控制信息和第二上行控制信息的完整性。通过容量来进行选择,能够尽量保证业务的可靠性需求。
在一个可能的设计中,终端设备从第一上行控制信道和第二上行控制信道中确定目标上行控制信道,包括:终端设备根据第一上行控制信息对应的业务类型,以及第一上行控制信道的结束时刻和第二上行控制信道的结束时刻确定目标上行控制信道。相应的,网络设备从第一上行控制信道和第二上行控制信道中确定目标上行控制信道,包括:网络设备根据第一上行控制信息对应的业务类型,以及第一上行控制信道的结束时刻和第二上行控制信道的结束时刻确定目标上行控制信道。
其中,在第一上行控制信息是第一类型业务对应的控制信息,且第一上行控制信道的结束时刻和第二上行控制信道的结束时刻相同情况下,目标上行控制信道是第一上行控制信道和第二上行控制信道中容量大的上行控制信道;
在第一上行控制信息是第一类型业务对应的控制信息,且第一上行控制信道的结束时刻和第二上行控制信道的结束时刻的差值小于或等于第一阈值的情况下,目标上行控制信道是第一上行控制信道和第二上行控制信道中容量大的上行控制信道;
在第一上行控制信息是第一类型业务对应的控制信息,且第一上行控制信道的结束时刻和第二上行控制信道的结束时刻不相同的情况下,目标上行控制信道是第一上行控制信道和第二上行控制信道中结束时刻早的上行控制信道;
在第一上行控制信息是第一类型业务对应的控制信息,且第一上行控制信道的结束时 刻和第二上行控制信道的结束时刻的差值大于第一阈值的情况下,目标上行控制信道是第一上行控制信道和第二上行控制信道中结束时刻早的上行控制信道;
其中,第一类型业务的服务时延要求小于或等于预设时延阈值和/或第一类型业务的服务误码率要求小于或等于预设误码率阈值。
根据上行控制信息的业务类型以及上行控制信道的结束时刻来确定目标上行控制信道,是确定目标上行控制信道的另一种方式。
不同的上行控制信息对于时延的要求可能不同。例如,第一类型业务的服务时延要求小于或等于预设时延阈值,和/或,第一类型业务的服务误码率要求小于或等于预设误码率阈值,也就是说第一类型业务对于时延的要求比较高。那么对于这类业务对应的上行控制信息,就需要及时传输给网络设备,以满足业务的可靠性需求。那么,如果只通过容量来选择,可能有时就无法满足时延的要求。鉴于这种情况,本发明实施例在选择目标上行控制信道时,也可以考虑上行控制信息对应的业务类型以及时间信息。在考虑时间信息时,可以考虑上行控制信道的结束时刻。
如果第一上行控制信道的结束时刻和第二上行控制信道的结束时刻相同,或者第一上行控制信道的结束时刻和第二上行控制信道的结束时刻之间的差值小于或等于第一阈值,都表明这两个上行控制信道的结束时刻差别不大,无论选择其中哪个上行控制信道作为目标上行控制信道,对于第一类型业务对应的上行控制信息的影响都不会太大,即传输时延差不多。那么在这种情况下,终端设备同样可以结合进一步的因素来选取目标上行控制信道,例如终端设备可以出于上行控制信息能够完整传输的考虑,选取第一上行控制信道和第二上行控制信道中容量大的上行控制信道作为目标上行控制信道,以尽量保证第一上行控制信息和第二上行控制信息都能够得到完整传输,避免丢弃信息。
或者,如果第一上行控制信道的结束时刻和第二上行控制信道的结束时刻之间的差值大于第一阈值,那么就表明,如果选择了其中结束时刻晚的上行控制信道作为目标上行控制信道,则通过这样的目标上行控制信道来发送第一类型业务对应的上行控制信息,可能无法满足第一类型业务的时延需求。因此,如果第一上行控制信道的结束时刻和第二上行控制信道的结束时刻之间的差值大于第一阈值,则终端设备就确定选取第一上行控制信道和第二上行控制信道中结束时刻早的上行控制信道作为目标上行控制信道。通过判断第一上行控制信道的结束时刻和第二上行控制信道的结束时刻之间的差值,可以使得终端设备能够更为准确地选取目标上行控制信道。
或者,例如第一类型业务为URLLC业务。由于URLLC业务是业务紧急带来的较高时延要求,此时,PUCCH中传输的上行控制信息包括下行URLLC数据所对应的HARQ-ACK信息。如果HARQ-ACK信息是NACK,网络设备需要根据该NACK信息向终端设备重新发送之前的下行URLLC数据,以便下行URLLC业务可以在规定的时延要求内达到规定的可靠性需求。如果HARQ-ACK信息是ACK,则网络设备可以确定向终端设备发送的下行URLLC数据已经在终端设备侧接收正确。可以看到,在PUCCH中携带的信息包括HARQ-ACK的情况下,如果只是通过容量来选择上行控制信道,那么如果选择的目标上行控制信道的结束时刻较晚,则把HARQ-ACK放在结束时刻晚的上行控制信道中发送,将会影响下行URLLC业务和上行URLLC业务的低时延和高可靠性的服务需求。因此,第一上行控制信息和第二上行控制信息中只要有一个上行控制信息对应的是第一类型业务信息,且第一上行控制信道和第二上行控制信道的结束时刻不同,终端设备就可以选择第一上行控制信道 和第二上行控制信道中结束时刻早的上行控制信道作为目标上行控制信道,通过这种方式来尽量保证第一类型业务的时延需求。
在一个可能的设计中,终端设备从第一上行控制信道和第二上行控制信道中确定目标上行控制信道,包括:终端设备根据第一上行控制信息对应的业务类型,以及第一上行控制信道的容量和第二上行控制信道的容量,从第一上行控制信道和第二上行控制信道中确定目标上行控制信道。相应的,网络设备从第一上行控制信道和第二上行控制信道中确定目标上行控制信道,包括:网络设备根据第一上行控制信息对应的业务类型,以及第一上行控制信道的容量和第二上行控制信道的容量,从第一上行控制信道和第二上行控制信道中确定目标上行控制信道。其中,在第一上行控制信息是第一类型业务对应的控制信息的情况下,目标上行控制信道是第一上行控制信道和第二上行控制信道中容量大的上行控制信道。第一类型业务的服务时延要求小于或等于预设时延阈值和/或第一类型业务的服务误码率要求小于或等于预设误码率阈值。
根据上行控制信息对应的业务类型和上行控制信道的容量来选择目标上行控制信道,是选择目标上行控制信道的另一种方式。对于第一类型业务来说,是有可靠性的需求的,因此,为了尽量保证信息的完整传输,可以直接从第一上行控制信道和第二上行控制信道中选择容量大的上行控制信道作为目标上行控制信道,避免丢弃信息。
在一个可能的设计中,第一上行控制信道和第二上行控制信道在时间上有重叠。则,终端设备从第一上行控制信道和第二上行控制信道中确定目标上行控制信道,包括:终端设备根据第一上行控制信道的结束时刻和第二上行控制信道的结束时刻确定目标上行控制信道,相应的,网络设备从第一上行控制信道和第二上行控制信道中确定目标上行控制信道,包括:网络设备根据第一上行控制信道的结束时刻和第二上行控制信道的结束时刻确定目标上行控制信道。
其中,目标上行控制信道是第一上行控制信道和第二上行控制信道中结束时刻早的上行控制信道;或者
在第一上行控制信道的结束时刻与第二上行控制信道的结束时刻之间的差值大于第一阈值的情况下,目标上行控制信道是第一上行控制信道和第二上行控制信道中结束时刻早的上行控制信道;或者
在第一上行控制信道的结束时刻与第二上行控制信道的结束时刻之间的差值小于或等于第一阈值的情况下,目标上行控制信道是第一上行控制信道或第二上行控制信道。
无论传输哪种上行控制信息,自然是时延越小越好。因此,即使不考虑第一上行控制信息和第二上行控制信息的业务类型,终端设备也可以根据上行控制信道的时间信息来选择目标上行控制信道。例如,终端设备可以直接选择第一上行控制信道和第二上行控制信道中结束时刻早的上行控制信道作为目标上行控制信道,以尽量减小传输时延。
或者,终端设备也可以考虑第一上行控制信道的结束时刻与第二上行控制信道的结束时刻之间的差值。如果第一上行控制信道的结束时刻和第二上行控制信道的结束时刻之间的差值大于第一阈值,那么就表明,如果选择了其中结束时刻晚的上行控制信道作为目标上行控制信道,则通过这样的目标上行控制信道来发送上行控制信息,可能会导致上行控制信息的传输时延较大,这就可能无法满足业务或系统的时延需求。因此,如果第一上行控制信道的结束时刻和第二上行控制信道的结束时刻之间的差值大于第一阈值,则终端设备就确定选取第一上行控制信道和第二上行控制信道中结束时刻早的上行控制信道作为 目标上行控制信道。而如果第一上行控制信道的结束时刻和第二上行控制信道的结束时刻之间的差值小于或等于第一阈值,那么就表明这两个上行控制信道的结束时刻差别不是很大,无论选择其中哪个上行控制信道作为目标上行控制信道,对于第一类型业务对应的上行控制信息的影响都不会太大,即传输时延可能差不多。那么在这种情况下,终端设备就可以结合进一步的因素来选取目标上行控制信道,例如终端设备可以任选第一上行控制信道或第二上行控制信道作为目标上行控制信道,或者,因为此时无论选择哪个上行控制信道,时延都可以基本得到满足,那么出于上行控制信息能够完整传输的考虑,终端设备可以选取第一上行控制信道和第二上行控制信道中容量大的上行控制信道作为目标上行控制信道,以尽量保证第一上行控制信息和第二上行控制信息都能够得到完整传输,避免丢弃信息。当然终端设备还可以结合其他因素来从第一上行控制信道和第二上行控制信道中选择目标上行控制信道,本发明实施例不作限制。
在一个可能的设计中,第一上行控制信道和第二上行控制信道在时间上有重叠。则,终端设备从第一上行控制信道和第二上行控制信道中确定目标上行控制信道,包括:终端设备根据第一上行控制信道的开始时刻和第二上行控制信道的开始时刻,和/或,根据第一上行控制信道的结束时刻和第二上行控制信道的结束时刻,确定目标上行控制信道。相应的,网络设备从第一上行控制信道和第二上行控制信道中确定目标上行控制信道,包括:网络设备根据第一上行控制信道的开始时刻和第二上行控制信道的开始时刻,和/或,根据第一上行控制信道的结束时刻和第二上行控制信道的结束时刻,确定目标上行控制信道。其中,
在第二上行控制信道的结束时刻早于第一上行控制信道的结束时刻,且第二上行控制信道的开始时刻和第一上行控制信道的开始时刻的差小于第二阈值的情况下,目标上行控制信道是第二上行控制信道;或者
在第二上行控制信道的结束时刻晚于第一上行控制信道,或者第二上行控制信道的结束时刻早于第一上行控制信道的结束时刻,且第二上行控制信道的开始时刻和第一上行控制信道的开始时刻的差大于或等于第二阈值的情况下,目标上行控制信道是第一上行控制信道。
在本发明实施例中,终端设备除了可以结合第一上行控制信道的结束时刻和第二上行控制信道的结束时刻之间的差值来选择目标上行控制信道,也可以结合第一上行控制信道的开始时刻和第二上行控制信道的开始时刻之间的差值来选择目标上行控制信道。
如果第二上行控制信道的结束时刻早于第一上行控制信道的结束时刻,且第二上行控制信道的开始时刻和第一上行控制信道的开始时刻的差小于第二阈值,表明第一上行控制信道和第二上行控制信道之间的差值比较小,无论是哪个上行控制信道可能都不会开始的太早,应该无论哪个上行控制信道都不至于在终端设备得到上行控制信息之前就开始传输或传输完毕,那么在这种情况下,终端设备就可以选择这两个上行控制信道中结束时刻早的上行控制信道,即,在能够保证上行控制信息得到传输的情况下,可以尽量通过选择结束时刻早的上行控制信道来减小传输时延。
而如果第二上行控制信道的结束时刻早于第一上行控制信道的结束时刻,且第二上行控制信道的开始时刻和第一上行控制信道的开始时刻的差大于或等于第二阈值,表明第一上行控制信道和第二上行控制信道之间的差值比较大,如果选择了其中开始时刻早的上行控制信道作为目标上行控制信道,可能会导致在终端设备解调下行数据之前或将下行数据 解调完毕之前目标上行控制信道就已开始传输或传输完毕,从而导致终端设备生成的上行控制信息不能完整传输甚至不能传输。因此在这种情况下,可以尽量选择结束时刻晚的上行控制信道作为目标上行控制信道,因为如果结束时刻晚,则可以多一些时间等待终端设备解调下行数据,尽量保证上行控制信息能够得到传输。
在一个可能的设计中,
第一上行控制信息是混合自动重传应答信息,第二上行控制信息是第一类型信道状态信息;或者
第一上行控制信息是第二类型信道状态信息,第二上行控制信息是第一类型信道状态信息;或者
第一上行控制信息是第一类型调度请求信息,第二上行控制信息是混合自动重传应答信息、第一类型信道状态信息和第二类型信道状态信息中的任意一种。
给出了第一上行控制信息和第二上行控制信息的实现方式,当然本发明实施例不限于这些实现方式。
在一个可能的设计中,第一类型信道状态信息是周期信道状态信息,第二类型信道状态信息是低时延信道状态信息,第一类型调度请求信息是用于请求第一类型业务的服务的调度请求,第一类型业务的服务时延要求小于或等于预设时延阈值和/或第一类型业务的服务误码率要求小于或等于预设误码率阈值。
在一个可能的设计中,在终端设备在目标上行控制信道发送目标上行控制信息之前,还包括:终端设备接收配置信息,配置信息用于指示允许终端设备同时传输第一上行控制信息和第二上行控制信息。相应的,网络设备还向终端设备发送该配置信息,该配置信息用于指示允许终端设备同时传输第一上行控制信息和第二上行控制信息。
终端设备接收配置信息后,就可以确定能够同时传输第一上行控制信息和第二上行控制信息,则终端设备就可以按照如前介绍的方式来选择目标上行控制信道。而如果网络设备未向终端设备发送该配置信息,那么终端设备可以选择在第一上行控制信道发送第一上行控制信息,在第二上行控制信道发送第二控制信息,即,在各自的上行控制信道分别发送相应的上行控制信息。或者,如果网络设备未向终端设备发送该配置信息,则终端设备也可以从第一上行控制信道和第二上行控制信道中选择一个上行控制信道来发送第一上行控制信息或第二上行控制信息,至于究竟选择发送第一上行控制信息还是第二上行控制信息,本发明实施例不限制选择方式。
在一个可能的设计中,目标上行控制信息包括第一上行控制信息和第二上行控制信息中优先级最高的N比特信息。其中,N小于或等于目标上行控制信道的容量所对应的比特数。
即,终端设备所发送的目标上行控制信息要与目标上行控制信道的容量相适应。N比特信息可以是第一上行控制信息包括的N比特信息,或者可以是第二上行控制信息包括的N比特信息,或者N比特信息可以包括第一上行控制信息的全部内容,以及包括第二上行控制信息的部分内容,或者N比特信息可以包括第二上行控制信息的全部内容,以及包括第一上行控制信息的部分内容。也就是说,如果第一上行控制信息和第二上行控制信息的总容量小于或等于目标上行控制信道的容量,则终端设备就可以完整发送第一上行控制信息和第二上行控制信息,以保证信息的完整性。而如果第一上行控制信息和第二上行控制信息的总容量大于目标上行控制信道的容量,则终端设备可以选择发送第一上行控制信息 和第二上行控制信息中优先级最高的N比特信息,以尽量保证优先级高的信息能够得到发送。

具体实施方式
为了使本发明实施例的目的、技术方案和优点更加清楚,下面将结合附图对本发明实施例作进一步地详细描述。
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)终端设备,包括向用户提供语音和/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。该终端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。该终端设备可以包括用户设备(User Equipment,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,智能穿戴式设备等。例如,个人通信业务(Personal Communication Service,PCS)电话、无绳电话、会话发起协议(Session Initiation Protocol,SIP)话机、无线本地环路(Wireless Local Loop,WLL)站、个人数字助理(Personal Digital Assistant,PDA)、智能手表、智能头盔、智能眼镜、智能手环、等设备。还包括受限设备,例如功耗较低的设备,或存储能力有限的设备,或计算能力有限的设备等。例如包括条码、射频识别(Radio Frequency Identification,RFID)、传感器、全球定位系统(Global Positioning System,GPS)、激光扫描器等信息传感设备。
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 一个或多个小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LTE系统或演进的LTE系统(LTE-Advanced,LTE-A)中的演进型基站(NodeB或eNB或e-NodeB,evolutional Node B),或者也可以包括第五代移动通信技术(Fifth Generation,5G)新无线(New Radio,NR)系统中的下一代节点B(next generation node B,gNB),本发明实施例并不限定。
3)上行控制信道,承载的信息包括上行控制信息的信道。本文不限制上行控制信道究竟包括哪些信道,例如包括PUCCH或增强的物理上行控制信道(Enhanced Physical Uplink Control Channel,EPDCCH),还可包括其他用于传输控制信息的上行控制信道。
4)低时延信道状态信息(Low Latency Channel State Information,LL-CSI)。
为了在苛刻的时延要求下满足可靠性,一种多次重复传输的技术被提出。如图1A,根据信道质量在数据发送之前确定需要重传的次数和调制编码方式,通过4次重复传输来获取可靠性增益。理论上,白噪声信道下,数据每重复一次可获取3dB的可靠性提升。重复次数可以是预先配置的,也可以是由ACK反馈来实现终止。但如果多次重复传输均采用相同的调制与编码策略(Modulation and Coding Scheme,MCS),则无法应对信道质量随时间的变化情况,导致重复传输对可靠性提升效果减弱。因此,一种信道状态反馈方式如图1B所示。终端设备收到重传(Repetition)数据后,向网络设备反馈LL-CSI,则网络设备就会调整MCS。
LL-CSI是终端设备接收下行数据后根据该下行数据对应的解调参考信号生成的,是不需要终端设备对该下行数据进行数据解调解码就可以快速获得并反馈的信道质量信息。LL-CSI由终端设备接收到下行数据触发,并且LL-CSI是基于下行数据对应的解调参考信号测量得到的。在终端设备对该下行数据进行数据解调解码之前即可向网络设备反馈LL-CSI,便于网络设备在后续重复传输或者重传时及时调整该下行数据的调度方式,特别是对于下行的超可靠低时延通信(Ultra Reliable Low Latency Communication,URLLC)数据来说,LL-CSI可以满足URLLC数据的低时延和高可靠性需求。例如,LL-CSI可以是MCS相对于终端设备之前使用的MCS的偏移值或信道质量指示(Channel Quality Indicato,CQI)相对于终端设备之前上报的CQI的偏移值等。
5)本发明实施例中的术语“系统”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。
以及,除非有相反的说明,本发明实施例提及“第一”、“第二”等序数词是用于对多个对象进行区分,不用于限定多个对象的顺序、时序、优先级或者重要程度。
如上介绍了本发明实施例涉及的一些概念,下面介绍一下本发明实施例的技术背景。
NR系统中支持多种子载波间隔来适应不同的业务需求。在频域上,NR系统支持的子载波间隔的计算方式为f sc=f 0*2 m。其中,f 0=15kHz,m是整数。在时域上,提供了如下一些时间单位,包括:
■子帧(subframe),1个subframe的长度为1ms,在15kHz子载波间隔的结构 (numerology)下包括14个正交频分复用(Orthogonal Frequency Division Multiplexing,OFDM)符号。在1个subframe内,对15kHz以及15kHz以上的子载波间隔的各种numerology的符号边界是对齐的。其中,如无特殊说明,则下文中的“符号”均是指OFDM符号。
■时隙(slot),是一种可能的调度单元的时间长度。1个slot包括当前使用的numerology下的y个符号。1个subframe中包括整数个slot。例如,在子载波间隔是60KHz以下的情况时,y=7;在子载波间隔是60kHz以上的情况时,y=14。
■迷你时隙(Mini-slot),是调度单元的最小时间长度。1个Mini-slot包括的OFDM符号可以小于当前使用的numerology下的y个符号。
可参考图2A、图2B和图2C,其中图2A为子载波间隔是15KHz时subframe与slot、以及Mini-slot的示意,图2B为子载波间隔是30KHz时slot与Mini-slot的示意,图2C为子载波间隔是60KHz时slot与Mini-slot的示意。
终端设备可以向网络设备发送上行控制信息(Uplink Control Information,UCI),具体的,终端设备通过网络设备配置的上行控制信道向网络设备发送UCI。以上行控制信道是PUCCH为例,在NR系统中,为保证PUCCH传输的效率,有必要为终端设备配置不同格式或者不同资源量的PUCCH资源。
UCI例如包括HARQ-ACK、周期CSI、调度请求(Scheduling Request,SR)、LL-CSI等。
首先介绍UCI包括HARQ-ACK的情况。目前,下行数据传输是基于基站调度的。具体的调度流程是,基站发送下行控制信道,例如物理下行控制信道(Physical Downlink Control Channel,PDCCH)或增强的物理下行控制信道(Enhanced Physical Downlink Control Channel,EPDCCH),该下行控制信道可以承载物理下行共享信道(Physical Downlink Shared Channel,PDSCH)或PUSCH的调度信息,该调度信息例如包括资源分配信息或调制编码方式等控制信息。终端设备检测下行控制信道,并根据检测的下行控制信道承载的调度信息来进行下行数据信道的接收或上行数据信道的发送。
在支持HARQ传输的情况下,终端设备在接收下行数据后,如果接收正确,则终端设备在PUCCH上向基站反馈肯定应答(ACK),如果接收不正确,则终端设备在PUCCH上向基站反馈否定应答(NACK)。其中,ACK和NACK统称为HARQ-ACK。如果基站接收到终端设备对下行数据的NACK反馈,则基站可对该下行数据做重传调度。而如果基站接收到终端设备对下行数据的ACK反馈,则如果没有更多的下行数据待传输,基站就可暂停为该终端设备调度下行资源。
接下来介绍UCI包括SR的情况。终端设备需要通过SR告诉基站自己是否有上行数据需要传输,以便基站决定是否给终端设备分配上行资源。基站收到SR后,给终端设备分配上行资源用于终端设备发送上行数据。如果终端设备需要传输的上行数据是URLLC数据,则终端设备需要在有上行数据传输需求时,尽快向基站发送SR,基站接收到终端设备的SR后需尽快向终端设备指示用于发送上行数据的资源。但是对于非URLLC的其它类型的上行数据,终端设备发送SR以及基站根据SR调度终端设备发送上行数据的紧急程度一般没有URLLC上行数据的紧急程度高。
因此,为满足基站对URLLC数据的快速调度,终端设备发送的SR可区分是URLLC的上行数据请求还是其它类型的(例如增强的移动宽带(Enhanced Mobile Broad Band, eMBB))的上行数据请求。区分方式包括根据SR的内容以及根据发送SR的资源区分。例如,基站为终端设备分配用于发送SR的资源,终端设备在该资源发送不同的信息对应的不同的上行数据调度请求。例如,如果终端设备在该SR的资源发送“00”,则代表请求基站调度的是eMBB的上行数据传输,如果终端设备在该SR的资源发送“01”,则代表请求基站调度的是URLLC的上行数据传输。或者,基站为终端设备分配用于发送URLLC的SR的资源,以及为UE分配用于发送eMBB的SR的资源,则终端设备根据上行数据传输的类型就能确定在哪个资源发送SR,而基站也就可以区分接收的SR是何种类型的数据对应的SR。
接下来介绍UCI包括周期CSI的情况。网络设备向终端设备配置反馈周期CSI的周期以及反馈周期CSI的PUCCH资源。在载波聚合的场景下,每个下行载波的反馈周期独立配置。终端设备需要计算CSI,并将CSI按照周期配置的参数反馈给网络设备,从而网络设备可以对终端设备进行调度。
再介绍UCI包括LL-CSI的情况。终端设备接收下行数据后,根据该下行数据对应的解调参考信号生成LL-CSI,在终端设备对该下行数据进行数据解调解码之前即可向网络设备反馈该LL-CSI,便于网络设备在后续重复传输或者重传时及时调整该下行数据的调度方式,
其中,用于终端设备发送UCI的PUCCH资源可以是基站为该终端设备配置的资源。该配置的PUCCH资源包括PUCCH占用的时间、频率、及参考信号序列等至少一项。另外,PUCCH资源还可以包括PUCCH和PDSCH之间的时间间隔的备选值,或者包括PUCCH和PDCCH之间的时间间隔的备选值。
目前,如果终端设备在一个上行子帧发送HARQ-ACK,UE可根据确定HARQ-ACK对应的PUCCH资源的规则确定出该上行子帧的第一PUCCH资源,该第一PUCCH资源和HARQ-ACK信息对应。如果终端设备在一个上行子帧发送周期CSI,UE可根据确定周期CSI对应的PUCCH资源的规则确定出该上行子帧的第二PUCCH资源,该第二PUCCH资源和周期CSI信息对应。如果终端设备在一个上行子帧发送SR,UE可根据确定SR对应的PUCCH资源的规则确定出该上行子帧的第三PUCCH资源,该第三PUCCH资源和SR对应。如果终端设备在一个上行子帧发送LL-CSI,UE可根据确定LL-CSI对应的PUCCH资源的规则确定出该上行子帧的第四PUCCH资源,该第四PUCCH资源和LL-CSI信息对应。
那么,如果终端设备在一个上行子帧要发送HARQ-ACK、周期CSI、SR和LL-CSI中的至少两种,目前的方式是分别在各自对应的PUCCH资源上发送,即,终端设备在第一PUCCH资源发送HARQ-ACK,在第二PUCCH资源发送周期CSI,在第三PUCCH资源发送SR,在第四PUCCH发送LL-CSI。但是,一方面,如果第一PUCCH资源、第二PUCCH资源、第三PUCCH资源、第四PUCCH资源在频率上不连续,而且对第一PUCCH资源上发送的HARQ-ACK、第二PUCCH资源上发送的周期CSI、第三PUCCH资源上发送的SR、第四PUCCH资源上发送的LL-CSI的信号分别执行DFT的话,终端设备在该上行子帧发送的信号的PAPR就比较大,导致终端设备的功率效率很低。另一方面,第一PUCCH资源、第二PUCCH资源、第三PUCCH资源和第四PUCCH资源上发送的信号之间的IMD,会导致HARQ-ACK和周期CSI的接收性能都较差。
或者,如果终端设备在一个上行子帧要发送HARQ-ACK、周期CSI、SR和LL-CSI中的至少两种,一种设想的方式是:终端设备根据待反馈的各种UCI的信息量或者待反馈的各种UCI的类型从多个PUCCH资源中确定一个PUCCH资源,并在选择的PUCCH资源中反馈 所有的UCI。例如:如果终端设备在同一子帧待反馈的UCI包括HARQ-ACK和周期CSI,如果HARQ-ACK对应的是主载波的下行数据的HARQ-ACK,并且周期CSI的信息量是一个小区的CSI,则选择的PUCCH资源是周期CSI对应的PUCCH信道;如果HARQ-ACK对应的信息量大于2比特,则选择的PUCCH资源是HARQ-ACK对应的PUCCH信道。如果终端设备在同一子帧待反馈的UCI包括HARQ-ACK和SR,如果HARQ-ACK对应的是主载波的下行数据的HARQ-ACK,则选择的PUCCH资源是SR对应的PUCCH信道;如果HARQ-ACK对应的信息量大于2比特,则选择的PUCCH资源是HARQ-ACK对应的PUCCH信道,等等。
可以看到,这种设想的方式中,终端设备选择目PUCCH资源时依然没有考虑选择的PUCCH资源的选择对于上行控制信息所对应的业务服务的时延和可靠性的影响。
鉴于此,提出了本发明实施例的技术方案。本发明实施例中,如果终端设备要传输两个上行控制信息,那么终端设备就从两个上行控制信息分别对应的上行控制信道中选择一个作为目标上行控制信道,并通过目标上行控制信道发送两个上行控制信息,例如上行控制信道为PUCCH,那么本发明实施例就是将多个上行控制信息放到一个PUCCH资源中发送,通过这种方式可以减小终端设备在上行子帧发送的信号的PAPR,提高终端设备的功率效率。另一方面,由于将多个上行控制信息通过一个目标上行控制信道发送,减小了信号之间的IMD,从而能够增强上行控制信息的接收性能。其中,目标上行控制信道是两个上行控制信道中容量较大或者结束时间较晚的信道,通过这种方式可以满足服务时延要求小于或等于预设时延阈值和/或服务误码率要求小于或等于预设误码率阈值的高可靠低时延通信URLLC业务对于该上行控信息传输的需求。其中在本发明实施例中,上行控制信道和上行控制信道资源可以认为是相同的概念,即,终端设备选择上行控制信道,可以理解为终端设备选择上行控制信道资源,终端设备通过上行控制信道发送上行控制信息,可以理解为终端设备通过上行控制信道资源发送上行控制信息。
请参考图3,介绍本发明实施例的一种应用场景。图3中包括网络设备和两个终端设备,终端设备可通过上行控制信道向网络设备传输上行控制信息。图3中的网络设备例如为基站。
本文所提供的技术方案可以应用于5G NR系统(下文简称NR系统),还可以应用于下一代移动通信系统或其他类似的移动通信系统。
下面结合附图介绍本发明实施例提供的技术方案。
请参见图4,本发明一实施例提供一种控制信息发送、接收方法,在下文的介绍过程中,均以本发明实施例提供的方法应用于图3所示的应用场景、以终端设备传输两种上行控制信息为例。其中,终端设备传输的两种上行控制信息包括第一上行控制信息和第二上行控制信息。
S41、终端设备从第一上行控制信道和第二上行控制信道中确定目标上行控制信道。其中,第一上行控制信道对应第一上行控制信息,第二上行控制信道对应第二上行控制信息。这里的第一上行控制信道与第一上行控制信息对应,是指第一上行控制信道是网络设备分配给终端设备用于传输第一上行控制信息的,第二上行控制信道与第二上行控制信息对应的含义也是同样。
本发明实施例中,第一上行控制信息是混合自动重传应答信息,第二上行控制信息是第一类型信道状态信息;或,第一上行控制信息是第二类型信道状态信息,第二上行控制信息是第一类型信道状态信息;或,第一上行控制信息是第一类型调度请求信息,第二上 行控制信息是混合自动重传应答信息、第一类型信道状态信息和第二类型信道状态信息中的任意一种。
其中,第一类型信道状态信息是周期CSI,第二类型信道状态信息是LL-CSI,第一类型调度请求信息是用于请求第一类型业务的服务的调度请求,第一类型业务的服务时延要求小于或等于预设时延阈值,和/或,第一类型业务的服务误码率要求小于或等于预设误码率阈值。例如一种第一类型业务为URLLC业务。
在本发明实施例中,第一上行控制信道和第二上行控制信道可能是不同格式的上行控制信道,也可能是相同格式的上行控制信道。第一上行控制信道和第二上行控制信道包括的时间长度相同或者不同。但第一上行控制信道和第二上行控制信道在时间上部分重叠或全部重叠。可参考图5A-图5D,为第一上行控制信道和第二上行控制信道在时间上部分重叠的几种情况,另外可参考图5E,为第一上行控制信道和第二上行控制信道在时间上完全重叠的情况。可以看到,第一上行控制信道包括的时间长度和第二上行控制信道包括的时间长度可以相同也可以不同,第一上行控制信道的开始时刻和第二上行控制信道的开始时刻可以相同也可以不同。如果第一上行控制信道和第二上行控制信道包括的时间长度不同,那么第一上行控制信道和第二上行控制信道可能在时间上不重叠或者部分重叠,其中,如果第一上行控制信道的时间长度小于第二上行控制信道的时间长度,则可能出现第一上行控制信道的时间长度包括在第二上行控制信道的时间长度内的情况。而如果第一上行控制信道和第二上行控制信道包括的时间长度相同,那么如果第一上行控制信道的开始时刻和第二上行控制信道的开始时刻不同,则第一上行控制信道和第二上行控制信道可能在时间上不重叠或者部分重叠,如果第一上行控制信道的开始时刻和第二上行控制信道的开始时刻相同,则第一上行控制信道和第二上行控制信道可能在时间上完全重叠。
如果两个不同的上行控制信道在时间上部分重叠,在重叠的时间内,考虑第一上行控制信道和第二上行控制信道在频率上可能不连续,例如终端设备同时在第一上行控制信道发送HARQ-ACK而在第二上行控制信道发送周期CSI,则终端设备发送的信号的PAPR较大,且发送的信号之间的IMD较大。因此本发明实施例中,终端设备可以从第一上行控制信道和第二上行控制信道中选择一个上行控制信道作为目标上行控制信道,通过目标上行控制信道来发送第一上行控制信息和/或第二上行控制信息。通过这种方式来减小信号的PAPR以及信号之间的IMD。并且,目标上行控制信道是两个上行控制信道中容量较大或者结束时间较晚的信道,通过这种方式可以满足服务时延要求小于或等于预设时延阈值和/或服务误码率要求小于或等于预设误码率阈值的URLLC业务对于该上行控信息传输的需求。
在本发明实施例中,终端设备可以通过多种方式来选择目标上行控制信道,下面介绍几种可选的方式。
方式A、通过第一上行控制信道的容量和第二上行控制信道的容量选择目标上行控制信道。
因为要同时传输第一上行控制信息和第二上行控制信息,则所需的容量可能较大。终端设备可选择容量大的上行控制信道作为目标上行控制信道,从而尽量保证第一上行控制信息和第二上行控制信息都能得到发送,避免因上行控制信道容量不足而导致丢弃UCI信息,造成对业务服务的影响。例如对于第一上行控制信道和第二上行控制信道,则终端设备就可以选择两者中容量大的作为目标上行控制信道,可保证终端设备可以将待反馈的 UCI信息尽可能多地反馈给网络设备,保证业务服务性能。可选的,终端设备可根据第一上行控制信道的格式或者第一上行控制信道相关的控制信息确定第一上行控制信道的容量,根据第二上行控制信道的格式或者第二上行控制信道相关的控制信息确定第二上行控制信道的容量。
例如终端设备在同一个上行时隙(slot)中要发送HARQ-ACK和周期CSI,上行控制信道为PUCCH,与HARQ-ACK对应的PUCCH资源的格式是长PUCCH,可参考图6,以该slot包括7个符号为例,与HARQ-ACK对应的PUCCH资源占用其中的4个符号。与周期CSI对应的PUCCH资源的格式也是长PUCCH,可继续参考图6,与周期CSI对应的PUCCH资源占用该slot的5个符号。那么终端设备就可以选择与周期CSI对应的PUCCH资源作为目标PUCCH资源,通过该目标PUCCH资源来发送HARQ-ACK和周期CSI。
但是,不同的上行控制信息对于时延的要求可能不同。例如,第一类型业务的服务时延要求小于或等于预设时延阈值,和/或,第一类型业务的服务误码率要求小于或等于预设误码率阈值,也就是说第一类型业务对于时延的要求比较高。那么对于这类业务对应的上行控制信息,就需要及时传输给网络设备,以满足业务的可靠性需求。或者,也可能有一些临时的紧急业务会对时延的要求比较高,此类业务对应的上行控制信息也需要及时传输给网络设备。那么,如果只通过容量来选择,可能有时就无法满足时延的要求。
鉴于这种情况,本发明实施例在选择目标上行控制信道时,也可以考虑上行控制信息对应的业务类型以及时间信息。在考虑时间信息时,可以考虑上行控制信道的结束时刻,也可以考虑上行控制信道的开始时刻。
方式B、终端设备可根据第一上行控制信息对应的业务类型,以及第一上行控制信道的结束时刻和第二上行控制信道的结束时刻来确定目标上行控制信道。
作为一种示例,在第一上行控制信息是第一类型业务对应的控制信息,且第一上行控制信道的结束时刻和第二上行控制信道的结束时刻不相同的情况下,目标上行控制信道是第一上行控制信道和第二上行控制信道中结束时刻早的上行控制信道。
例如第一类型业务为URLLC业务。由于URLLC业务是业务紧急带来的较高时延要求,此时,PUCCH中传输的上行控制信息包括下行URLLC数据所对应的HARQ-ACK信息。如果HARQ-ACK信息是NACK,网络设备需要根据该NACK信息向终端设备重新发送之前的下行URLLC数据,以便下行URLLC业务可以在规定的时延要求内达到规定的可靠性需求。如果HARQ-ACK信息是ACK,则网络设备可以确定向终端设备发送的下行URLLC数据已经在终端设备侧接收正确。可以看到,在PUCCH中携带的信息包括HARQ-ACK的情况下,如果只是通过容量来选择上行控制信道,那么如果选择的目标上行控制信道的结束时刻较晚,则把HARQ-ACK放在结束时刻晚的上行控制信道中发送,将会影响下行URLLC业务和上行URLLC业务的低时延和高可靠性的服务需求。因此,第一上行控制信息和第二上行控制信息中只要有一个上行控制信息对应的是第一类型业务信息,且第一上行控制信道和第二上行控制信道的结束时刻不同,终端设备就可以选择第一上行控制信道和第二上行控制信道中结束时刻早的上行控制信道作为目标上行控制信道,通过这种方式来尽量保证第一类型业务的时延需求。
作为另一种示例,在第一上行控制信息或第二上行控制信息是第一类型业务对应的控制信息,且第一上行控制信道的结束时刻和第二上行控制信道的结束时刻的差值大于第一阈值的情况下,目标上行控制信道是第一上行控制信道和第二上行控制信道中结束时刻早 的上行控制信道。
在如前的示例中,只要第一上行控制信道和第二上行控制信道的结束时刻不相同,终端设备就可以选取第一上行控制信道和第二上行控制信道中结束时刻早的上行控制信道作为目标上行控制信道。而在本示例中,终端设备还可以确定第一上行控制信道的结束时刻和第二上行控制信道的结束时刻之间的差值,如果第一上行控制信道的结束时刻和第二上行控制信道的结束时刻之间的差值大于第一阈值,那么就表明,如果选择了其中结束时刻晚的上行控制信道作为目标上行控制信道,则通过这样的目标上行控制信道来发送第一类型业务对应的上行控制信息,可能无法满足第一类型业务的时延需求。因此,如果第一上行控制信道的结束时刻和第二上行控制信道的结束时刻之间的差值大于第一阈值,则终端设备就确定选取第一上行控制信道和第二上行控制信道中结束时刻早的上行控制信道作为目标上行控制信道。通过判断第一上行控制信道的结束时刻和第二上行控制信道的结束时刻之间的差值,可以使得终端设备能够更为准确地选取目标上行控制信道。需要说明的是,第一阈值可以是预设的值。例如基站和终端设备中保存相同的预设值作为第一阈值。该第一阈值的预设值是无线通信系统中规定的固定的值。另外,第一阈值还可以是基站发送给终端设备的配置信息中指示的值。
作为另一种示例,在第一上行控制信息是第一类型业务对应的控制信息,且第一上行控制信道的结束时刻和第二上行控制信道的结束时刻的差值小于或等于第一阈值的情况下,目标上行控制信道是第一上行控制信道和第二上行控制信道中容量大的上行控制信道。其中,本发明实施例中,是以将第一上行控制信道的结束时刻和第二上行控制信道的结束时刻的差值等于阈值的情况划入本示例为例,实际上,也可以将第一上行控制信道的结束时刻和第二上行控制信道的结束时刻的差值等于阈值的情况划入上一示例,即,上一示例变为:在第一上行控制信息或第二上行控制信息是第一类型业务对应的控制信息,且第一上行控制信道的结束时刻和第二上行控制信道的结束时刻的差值大于或等于第一阈值的情况下,目标上行控制信道是第一上行控制信道和第二上行控制信道中结束时刻早的上行控制信道。也就是说,本发明实施例对于中值点的划分不做限制。
如果第一上行控制信道的结束时刻和第二上行控制信道的结束时刻之间的差值小于或等于第一阈值,那么就表明这两个上行控制信道的结束时刻差别不是很大,无论选择其中哪个上行控制信道作为目标上行控制信道,对于第一类型业务对应的上行控制信息的影响都不会太大,即传输时延可能差不多。那么在这种情况下,终端设备就可以结合进一步的因素来选取目标上行控制信道,例如终端设备可以任选第一上行控制信道或第二上行控制信道作为目标上行控制信道,或者,因为此时无论选择哪个上行控制信道,时延都可以基本得到满足,那么出于上行控制信息能够完整传输的考虑,终端设备可以选取第一上行控制信道和第二上行控制信道中容量大的上行控制信道作为目标上行控制信道,以尽量保证第一上行控制信息和第二上行控制信息都能够得到完整传输,避免丢弃信息。同上,第一阈值可以是预设的值。例如基站和终端设备中保存相同的预设值作为第一阈值。该第一阈值的预设值是无线通信系统中规定的固定的值。另外,第一阈值还可以是基站发送给终端设备的配置信息中指示的值。
作为另一种示例,在第一上行控制信息是第一类型业务对应的控制信息,且第一上行控制信道的结束时刻和第二上行控制信道的结束时刻相同的情况下,目标上行控制信道是第一上行控制信道和第二上行控制信道中容量大的上行控制信道。
如果第一上行控制信道的结束时刻和第二上行控制信道的结束时刻相同,表明这两个上行控制信道的结束时刻无差别,无论选择其中哪个上行控制信道作为目标上行控制信道,对于第一类型业务对应的上行控制信息的影响都不会太大,即传输时延差不多。那么在这种情况下,终端设备同样可以结合进一步的因素来选取目标上行控制信道,例如终端设备可以任选第一上行控制信道或第二上行控制信道作为目标上行控制信道,或者出于上行控制信息能够完整传输的考虑,终端设备可以选取第一上行控制信道和第二上行控制信道中容量大的上行控制信道作为目标上行控制信道,以尽量保证第一上行控制信息和第二上行控制信息都能够得到完整传输,避免丢弃信息。
其中,方式B中的几种示例,在实际应用中可以只使用其中任意一种,或者也可以使用其中的任意多种的组合。
方式B介绍的是终端设备根据上行控制信息对应的业务类型以及时间信息选择目标上行控制信道的方式,下面再介绍方式C,为根据上行控制信息对应的业务类型以及上行控制信道的容量来选择目标上行控制信道的方式。
方式C、终端设备可根据第一上行控制信息对应的业务类型,以及第一上行控制信道的容量和第二上行控制信道的容量从第一上行控制信道和第二上行控制信道中确定目标上行控制信道。
例如,在第一上行控制信息是第一类型业务对应的控制信息的情况下,目标上行控制信道是第一上行控制信道和第二上行控制信道中容量大的上行控制信道。
对于第一类型业务来说是有可靠性的需求的,因此,为了尽量保证信息的完整传输,可以直接从第一上行控制信道和第二上行控制信道中选择容量大的上行控制信道作为目标上行控制信道,避免丢弃信息。可选的,终端设备可根据第一上行控制信道的格式或者第一上行控制信道相关的控制信息确定第一上行控制信道的容量,根据第二上行控制信道的格式或者第二上行控制信道相关的控制信息确定第二上行控制信道的容量。
如上介绍的几种选择目标上行控制信道的方式中,或者考虑了上行控制信道的容量,或者考虑了上行控制信息对应的业务类型,或者二者均有考虑。下面再介绍选择目标上行控制信道的方式D,在方式D中,是根据上行控制信道的时间信息来选择目标上行控制信道。
方式D、根据第一上行控制信道的结束时刻和第二上行控制信道的结束时刻确定目标上行控制信道。
无论传输哪种上行控制信息,自然是时延越小越好。因此,即使不考虑第一上行控制信息和第二上行控制信息的业务类型,终端设备也可以根据上行控制信道的时间信息来选择目标上行控制信道。
作为一种示例,终端设备可选择第一上行控制信道和第二上行控制信道中结束时刻早的上行控制信道作为目标上行控制信道,从而尽量减小上行控制信息的传输时延。
在本发明实施例中,为了实现更为准确的选择,终端设备还可以结合第一上行控制信道的结束时刻和第二上行控制信道的结束时刻之间的差值来选择目标上行控制信道。
作为另一种示例,在第一上行控制信道的结束时刻与第二上行控制信道的结束时刻之间的差值大于第一阈值的情况下,目标上行控制信道是第一上行控制信道和第二上行控制信道中结束时刻早的上行控制信道。
如果第一上行控制信道的结束时刻和第二上行控制信道的结束时刻之间的差值大于 第一阈值,那么就表明,如果选择了其中结束时刻晚的上行控制信道作为目标上行控制信道,则通过这样的目标上行控制信道来发送上行控制信息,可能会导致上行控制信息的传输时延较大,这就可能无法满足业务或系统的时延需求。因此,如果第一上行控制信道的结束时刻和第二上行控制信道的结束时刻之间的差值大于第一阈值,则终端设备就确定选取第一上行控制信道和第二上行控制信道中结束时刻早的上行控制信道作为目标上行控制信道。通过判断第一上行控制信道的结束时刻和第二上行控制信道的结束时刻之间的差值,可以使得终端设备能够更为准确地选取目标上行控制信道。同上,第一阈值可以是预设的值。例如基站和终端设备中保存相同的预设值作为第一阈值。该第一阈值的预设值是无线通信系统中规定的固定的值。另外,第一阈值还可以是基站发送给终端设备的配置信息中指示的值。
作为另一种示例,在第一上行控制信道的结束时刻与第二上行控制信道的结束时刻之间的差值小于或等于第一阈值的情况下,目标上行控制信道是第一上行控制信道或第二上行控制信道。其中,本发明实施例中,是以将第一上行控制信道的结束时刻和第二上行控制信道的结束时刻的差值等于阈值的情况划入本示例为例,实际上,也可以将第一上行控制信道的结束时刻和第二上行控制信道的结束时刻的差值等于阈值的情况划入上一示例,即,上一示例变为:在第一上行控制信道的结束时刻与第二上行控制信道的结束时刻之间的差值大于或等于第一阈值的情况下,目标上行控制信道是第一上行控制信道和第二上行控制信道中结束时刻早的上行控制信道。
如果第一上行控制信道的结束时刻和第二上行控制信道的结束时刻之间的差值小于或等于第一阈值,那么就表明这两个上行控制信道的结束时刻差别不是很大,无论选择其中哪个上行控制信道作为目标上行控制信道,对于第一类型业务对应的上行控制信息的影响都不会太大,即传输时延可能差不多。那么在这种情况下,终端设备就可以结合进一步的因素来选取目标上行控制信道,例如终端设备可以任选第一上行控制信道或第二上行控制信道作为目标上行控制信道,或者,因为此时无论选择哪个上行控制信道,时延都可以基本得到满足,那么出于上行控制信息能够完整传输的考虑,终端设备可以选取第一上行控制信道和第二上行控制信道中容量大的上行控制信道作为目标上行控制信道,以尽量保证第一上行控制信息和第二上行控制信息都能够得到完整传输,避免丢弃信息。当然终端设备还可以结合其他因素来从第一上行控制信道和第二上行控制信道中选择目标上行控制信道,本发明实施例不作限制。
例如第一上行控制信息或第二上行控制信息为HARQ-ACK,则HARQ-ACK是需要终端设备对下行数据进行解调后才能生成的。如果上行控制信道开始的太早,终端设备可能还来不及解调下行数据或来不及将下行数据解调完毕,则终端设备还无法得到上行控制信息,这样可能出现终端设备生成上行控制信息后上行控制信道已经开始传输了的情况,导致上行控制信息得不到传输。因此在本发明实施例中,终端设备除了可以结合第一上行控制信道的结束时刻和第二上行控制信道的结束时刻之间的差值来选择目标上行控制信道,也可以结合第一上行控制信道的开始时刻和第二上行控制信道的开始时刻之间的差值来选择目标上行控制信道。下面介绍方式E,为另一种通过时间信息来选择目标控制信道的方式。
其中,方式D中的几种示例,在实际应用中可以只使用其中任意一种,或者也可以使用其中的任意多种的组合。
方式E、终端设备根据第一上行控制信道的开始时刻和第二上行控制信道的开始时刻,和/或,根据第一上行控制信道的结束时刻和第二上行控制信道的结束时刻,确定目标上行控制信道。
作为一种示例,在第二上行控制信道的结束时刻早于第一上行控制信道的结束时刻,且第二上行控制信道的开始时刻和第一上行控制信道的开始时刻的差小于第二阈值的情况下,目标上行控制信道是第二上行控制信道。
在考虑了两个上行控制信道的结束时刻的差值的情况下,还可以进一步考虑两个上行控制信道的开始时刻的差值。如果第二上行控制信道的结束时刻早于第一上行控制信道的结束时刻,且第二上行控制信道的开始时刻和第一上行控制信道的开始时刻的差小于第二阈值,表明第一上行控制信道和第二上行控制信道之间的差值比较小,无论是哪个上行控制信道可能都不会开始的太早,应该无论哪个上行控制信道都不至于在终端设备得到上行控制信息之前就开始传输或传输完毕,那么在这种情况下,终端设备就可以选择这两个上行控制信道中结束时刻早的上行控制信道,即,在能够保证上行控制信息得到传输的情况下,可以尽量通过选择结束时刻早的上行控制信道来减小传输时延。需要说明的是,第二阈值可以是预设的值。例如基站和终端设备中保存相同的预设值作为第二阈值。该第二阈值的预设值是无线通信系统中规定的固定的值。另外,第二阈值还可以是基站发送给终端设备的配置信息中指示的值。
作为另一种示例,在第二上行控制信道的结束时刻早于第一上行控制信道的结束时刻,且第二上行控制信道的开始时刻和第一上行控制信道的开始时刻的差大于或等于第二阈值的情况下,目标上行控制信道是第一上行控制信道。其中,本发明实施例中,是以将第一上行控制信道的开始时刻和第二上行控制信道的开始时刻的差值等于阈值的情况划入本示例为例,实际上,也可以将第一上行控制信道的开始时刻和第二上行控制信道的开始时刻的差值等于阈值的情况划入上一示例,即,上一示例变为:在第二上行控制信道的结束时刻早于第一上行控制信道的结束时刻,且第二上行控制信道的开始时刻和第一上行控制信道的开始时刻的差小于或等于第二阈值的情况下,目标上行控制信道是第二上行控制信道。
如果第二上行控制信道的结束时刻早于第一上行控制信道的结束时刻,且第二上行控制信道的开始时刻和第一上行控制信道的开始时刻的差大于或等于第二阈值,表明第一上行控制信道和第二上行控制信道之间的差值比较大,如果选择了其中开始时刻早的上行控制信道作为目标上行控制信道,可能会导致在终端设备解调下行数据之前或将下行数据解调完毕之前目标上行控制信道就已开始传输或传输完毕,从而导致终端设备生成的上行控制信息不能完整传输甚至不能传输。因此在这种情况下,可以尽量选择结束时刻晚的上行控制信道作为目标上行控制信道,因为如果结束时刻晚,则可以多一些时间等待终端设备解调下行数据,尽量保证上行控制信息能够得到传输。
作为另一种示例,在第二上行控制信道的结束时刻晚于第一上行控制信道的结束时刻的情况下,目标上行控制信道是第一上行控制信道。
在这种示例中,终端设备可以直接选择结束时刻早的上行控制信道作为目标上行控制信道,以减小上行控制信息的传输时延。
其中,方式E中的几种示例,在实际应用中可以只使用其中任意一种,或者也可以使用其中的任意多种的组合。
如上介绍了多种选择目标上行控制信道的方式,上面的各种方式可以单独使用,也可以结合其中的任意几种一起使用。终端设备可以结合不同的实际情况选择不同的方式来选择目标上行控制信道,或者具体通过哪种方式来选择目标上行控制信道也可以通过协议规定,本发明实施例不作限制。而且需要说明的是,如上的几种方式只是示例,并不是对本发明实施例的技术方案的限制,只要是从多个上行控制信道中选择一个上行控制信道的方式均在本发明实施例的保护范围之内。
在本发明实施例中,网络设备还可以向终端设备发送配置信息,该配置信息用于指示允许终端设备同时传输第一上行控制信息和第二上行控制信息,那么终端设备接收该配置信息后就确定可以同时传输第一上行控制信息和第二上行控制信息。如果网络设备未向终端设备发送该配置信息,那么终端设备可以选择在第一上行控制信道发送第一上行控制信息,在第二上行控制信道发送第二控制信息,即,在各自的上行控制信道分别发送相应的上行控制信息。或者,如果网络设备未向终端设备发送该配置信息,则终端设备也可以从第一上行控制信道和第二上行控制信道中选择一个上行控制信道来发送第一上行控制信息或第二上行控制信息,至于究竟选择发送第一上行控制信息还是第二上行控制信息,本发明实施例不限制选择方式。例如按照第一上行控制信息和第二上行控制信息的时延要求来选择,则可以选择发送第一上行控制信息和第二上行控制信息中对时延要求高的上行控制信息,或者可以按照第一上行控制信息和第二上行控制信息对应的业务的重要性来选择,则可以选择发送第一上行控制信息和第二上行控制信息中对应的业务重要性高的上行控制信息。
除了终端设备要从第一上行控制信道和第二上行控制信道中确定目标上行控制信道之外,网络设备也要从第一上行控制信道和第二上行控制信道中确定目标上行控制信道,网络设备可采用与终端设备相同的方式来从第一上行控制信道和第二上行控制信道中确定目标上行控制信道,可以认为,网络设备也在S41中确定了目标上行控制信道。
S42、终端设备在目标上行控制信道发送目标上行控制信息,则网络设备在目标上行控制信道接收目标上行控制信息。其中,目标上行控制信息包括第一上行控制信息和/或第二上行控制信息。
在本发明实施例中,终端设备所发送的目标上行控制信息可以包括第一上行控制信息和第二上行控制信息中优先级最高的N比特信息,其中,N小于或等于目标上行控制信道的容量所对应的比特数。即,终端设备所发送的目标上行控制信息要与目标上行控制信道的容量相适应。N比特信息可以是第一上行控制信息包括的N比特信息,或者可以是第二上行控制信息包括的N比特信息,或者N比特信息可以包括第一上行控制信息的全部内容,以及包括第二上行控制信息的部分内容,或者N比特信息可以包括第二上行控制信息的全部内容,以及包括第一上行控制信息的部分内容。也就是说,如果第一上行控制信息和第二上行控制信息的总容量小于或等于目标上行控制信道的容量,则终端设备就可以完整发送第一上行控制信息和第二上行控制信息,以保证信息的完整性。而如果第一上行控制信息和第二上行控制信息的总容量大于目标上行控制信道的容量,则终端设备可以选择发送第一上行控制信息和第二上行控制信息中优先级最高的N比特信息,以尽量保证优先级高的信息能够得到发送。
在本发明实施例中,网络设备会采用与终端设备相同的方式来从第一上行控制信道和第二上行控制信道中确定目标上行控制信道,从而可以通过目标上行控制信道接收目标上 行控制信息。可选的,网络设备也知晓终端设备发送的目标上行控制信息可以包括第一上行控制信息和第二上行控制信息中优先级最高的N比特信息。从而网络设备就能够在目标上行控制信道正确检测目标上行控制信息。
如上介绍了本发明实施例提供的控制信息传输方法,为了更便于理解,下面通过一些具体的示例来阐释该方法的部分示例的实现过程。
例如,网络设备通过高层信令配置终端设备是否允许HARQ-ACK(或者LL-CSI)和周期CSI同时传输。其中,HARQ-ACK(或者LL-CSI)对应第一PUCCH,周期CSI对应第二PUCCH。那么,该终端设备在一个上行子帧要同时发送HARQ-ACK(或者LL-CSI)和周期CSI时,采用如下方式:
a、如果高层信令配置允许该终端设备的HARQ-ACK(或者LL-CSI)和CSI同时传输,则:
a1、如果第二PUCCH的结束时刻晚于第一PUCCH的结束时刻,则终端设备在该上行子帧选择在HARQ-ACK(或者LL-CSI)对应的第一PUCCH上发送周期CSI和HARQ-ACK;
a2、如果第一PUCCH的结束时刻晚于第二PUCCH的结束时刻,则终端设备在该上行子帧选择在周期CSI对应的第二PUCCH上发送周期CSI和HARQ-ACK(或者LL-CSI)。
b、如果高层信令配置不允许该终端设备的HARQ-ACK(或者LL-CSI)和周期CSI同时传输,则该终端设备在一个上行子帧要同时发送HARQ-ACK(或者LL-CSI)和周期CSI时,因为相对来说HARQ-ACK对时延的要求更高,则终端设备在该上行子帧选择在HARQ-ACK(或者LL-CSI)对应的第一PUCCH上发送HARQ-ACK(或者LL-CSI),为了避免干扰,可以丢弃周期CSI。
再例如,网络设备通过高层信令配置终端设备是否允许HARQ-ACK(或者LL-CSI)和SR同时传输。其中,HARQ-ACK(或者LL-CSI)对应第一PUCCH,SR对应第三PUCCH。该终端设备在一个上行子帧要同时发送HARQ-ACK(或者LL-CSI)和SR时,采用如下方式:
c、如果高层信令配置允许该终端设备的HARQ-ACK(或者LL-CSI)和SR同时传输,则:
c1、如果第三PUCCH的结束时刻晚于第一PUCCH的结束时刻,则终端设备在该上行子帧选择在HARQ-ACK(或者LL-CSI)对应的第一PUCCH上发送HARQ-ACK和SR。
c2、如果第一PUCCH的结束时刻晚于第三PUCCH的结束时刻,则终端设备在该上行子帧选择在SR对应的第三PUCCH上发送SR。如果第三PUCCH承载SR之后还有剩余容量,则该终端设备也可以通过第三PUCCH的剩余容量来发送HARQ-ACK(或者LL-CSI),发送的HARQ-ACK(或者LL-CSI)可能是完整的信息,也可能是部分信息。
d、如果高层信令配置不允许该终端设备的HARQ-ACK(或者LL-CSI)和SR同时传输,则该终端设备在一个上行子帧要同时发送HARQ-ACK(或者LL-CSI)和SR时,因相对来说SR对于时延的要求更高,因此该终端设备可在该上行子帧选择在SR对应的第一PUCCH上发送SR,为了避免干扰,可丢弃HARQ-ACK(或LL-CSI)。
当然,因为是举例,以上的例子只阐释了如前提供的控制信息传输方法中的部分示例,对于其他示例,本领域技术人员自然知道应如何实施。
