Description
本申请要求于2019年07月12日提交中国专利局、申请号为201910631294.0、申请名称为“通信方法与通信装置”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。
本申请涉及通信领域,并且更具体而言,涉及一种通信方法与通信装置。
目前,在通信***中,网络设备可以通过高层信令配置在某些特定符号上传输上行信号或下行信号,这些特定符号被定义为灵活(flexible)属性,可以将其称为灵活符号。
如果终端设备在使用上述灵活符号发送上行信号之前,终端设备接收到了网络设备发送的下行控制信息(downlink control information,DCI),该DCI用于调度终端设备在该灵活符号上接收下行信号,此时,终端设备会放弃在该灵活符号上发送上行业务数据,转而在该灵活符号上接收该DCI调度的下行业务数据。
然而,在终端设备在接收该DCI调度的下行业务数据之前,如果终端设备在该DCI(例如,DCI#1)之后接收到另一DCI(例如,DCI#2),该DCI#2调度的业务数据的发送时刻早于DCI#1调度的业务数据的发送时刻,此时,终端设备可以确定是否放弃接收DCI#1调度的下行业务数据。
当终端设备确定放弃接收DCI#调度的下行业务数据时,对于是否要恢复在该灵活符号上发送上行业务数据,现有的协议尚未进行讨论。

顺序传输是指先发送的调度信息,其对应的调度数据先到达,且对应的反馈信息也会先到达;或者较晚发出的调度信息对应的调度数据不早于较早发出的调度信息对应的调度数据到达,且对应的反馈信息不早于较早发出的调度信息对应的反馈信息到达。其中,调度信息可以为PDCCH上承载的DCI,调度数据可以为PDSCH上承载的数据,反馈信息可以为混合自动重传请求确认(hybrid automatic repeat request-acknowledgment,HARQ-ACK)信息。
如图2所示,调度信息#1在slot#n到达,调度信息2在slot#(n+1)到达,调度数据#2不早于调度数据#1到达,HARQ-ACK信息#2不早于HARQ-ACK信息#1到达。其中,调度数据#1是通过调度信息#1调度的,HARQ-ACK信息#1是调度信息#1对应的HARQ-ACK信息,也可以称为是调度数据#1对应的HARQ-ACK信息。
非顺序传输
非顺序传输是指先发送的调度信息,其对应的调度数据后到达,或者对应的反馈信息后到达;或者较晚发出的调度信息对应的调度数据早于较早发出的调度信息对应的调度数据到达(情况#1),或者较晚发出的调度信息对应的HARQ-ACK信息早于较早发出的调度信息对应的HARQ-ACK信息到达(情况#2)。
如图3所示,对于情况#1:调度信息#1在slot#n到达,调度信息#2在slot#(n+1)到达,调度数据#2早于调度数据#1到达,但调度数据#2对应的HARQ-ACK信息#2不早于调度数据#1对应的HARQ-ACK信息#1到达。
对于情况#2:调度信息#1在slot#n到达,调度信息#2在slot#(n+1)到达,调度数据#1早于调度数据#2到达,但调度数据2对应的HARQ-ACK信息#2却早于调度数据#1对应的HARQ-ACK信息#1到达。
以上,对本申请实施例中涉及的技术术语做了简单描述。下面,对本申请实施例的无线通信的方法进行详细说明。
如图4所示,网络设备通过高层信令将slot#(n+3)上的符号配置为了灵活符号,所谓灵活符号,是指即可以用于上行传输,又可以用于下行传输的符号。即slot#(n+3)上的符号既可以用于上行传输,又可以用于下行传输。例如,网络设备通过高层信令调度终 端设备在slot#(n+3)上进行下行接收,此时,如果终端设备在slot#(n+3)上进行下行接收之前,接收到了来自网络设备的DCI(DCI#1),调度终端设备在slot#(n+3)上进行上行发送,即上行发送与下行接收所对应的时域资源发生了冲突。在这种情况下,终端设备会取消在slot#(n+3)上进行下行接收,转而在slot#(n+3)上执行上行发送操作。
如果终端设备在DCI#1之后接收到了来自网络设备的DCI#2,调度终端设备在slot#(n+2)上进行上行发送,此时,DCI#2便与DCI#1发生了非顺序传输。在这种情况下,终端设备会取消在slot#(n+3)上进行上行发送,此时,下行接收所对应的时域资源便不存在资源冲突的情况了,此时,是否要恢复在slot#(n+3)上进行下行接收,是非常值得讨论的。
因此,本申请实施例提供了一种无线通信的方法,有助于满足高层信令所调度的业务的性能需求。
以下,结合图5至图10,对本申请实施例提供的无线通信的方法进行详细说明。
图5是本申请实施例提供的无线通信的方法200的示意***互图。下面,对方法200的每个步骤进行详细说明。
在本申请实施例中,以终端设备和网络设备作为执行方法200的执行主体为例,对方法200进行说明。作为示例而非限定,执行方法200的执行主体也可以是对应终端设备的芯片和对应网络设备的芯片。
在S210中,网络设备向终端设备发送信令#1(即,第一信令的一例),信令#1指示终端设备在时域资源#1(即,第一时域资源)上接收信息#1(即,第一信息的一例)。相应地,终端设备接收来自网络设备的信令#1。
也就是说,网络设备通过信令#1通知终端设备在时域资源#1上接收信息#1,其中,信令#1可以是高层信令,例如,无线资源控制(radio resource control,RRC)信令。
例如,网络设备通过RRC信令向终端设备指示半持续性调度(semi-persistent scheduling,SPS)资源,并向终端设备发送SPS资源的激活命令,使得终端设备能够使用激活态的SPS资源接收或者发送数据,其中,激活态的SPS资源包括时域资源#1。
在S220中,网络设备向终端设备发送DCI#1(即,第一DCI的一例),DCI#1指示终端设备在时域资源#2(即,第二时域资源的一例)上发送信息#2(即,第二信息的一例),时域资源#1与时域资源#2在时域资源#4(即,第四时域资源的一例)上重叠,也称为时域资源#1与时域资源#2存在重叠,时域资源#4上的部分或者全部符号被配置为灵活符号,。相应地,终端设备接收来自网络设备的DCI#1。
通常认为DCI的优先级高于高层信令的优先级,因此,当时域资源#1与时域资源#2发生重叠时,终端设备可以取消执行信令#1的调度,转而执行DCI#1的调度。
在S230中,网络设备向终端设备发送DCI#2(即,第二DCI的一例),DCI#2指示终端设备在时域资源#3(即,第三时域资源的一例)上发送信息#3(即,第三信息的一例),DCI#2的起始时刻晚于DCI#1的起始时刻,时域资源#3的起始时刻早于时域资源#2的起始时刻。相应地,终端设备接收来自网络设备的DCI#2。
终端设备接收到DCI#2,由于DCI#2的起始时刻晚于DCI#1的起始时刻,并且时域资源#3的起始时刻早于时域资源#2的起始时刻,参考前面对非顺序传输的介绍,可以看出,DCI#2与DCI#1之间的调度发生了非顺序传输。
在S240中,终端设备根据是否在时域资源#2上发送信息#2,确定是否在时域资源#1上接收信息#1。
鉴于DCI#2与DCI#1之间的调度发生了非顺序传输,终端设备可以确定是否要执行DCI#1的调度,即确定是否要在时域资源#2上发送信息#2,根据确定结果,确定是否恢复执行信令#1的调度,即确定是否在时域资源#1上接收信息#1。
相应地,方法200还可以包括S250,网络设备可以根据是否在时域资源#2上接收信息#2,确定是否在时域资源#1上发送信息#1。
鉴于DCI#2与DCI#1之间的调度发生了非顺序传输,网络设备可以确定是否要在时域资源#2上接收信息#2,根据确定结果,确定是否在时域资源#1上发送信息#1。
需要说明的是,在S240与S250中,终端设备与网络设备各自得到的确定结果是相一致的,例如,当终端设备确定不在时域资源#2上发送信息#2时,相应地,网络设备会确定不在时域资源#2上接收信息#2;当终端设备确定在时域资源#2上发送信息#2时,相应地,网络设备会确定在时域资源#2上接收信息#2。
例如,当网络设备确定在时域资源#1上发送信息#1时,相应地,终端设备会确定在时域资源#1上接收信息#1;当网络设备确定不在时域资源#1上发送信息#1时,相应地,终端设备会确定不在时域资源#1上接收信息#1。
基于上述技术方案,当信令#1调度的业务与DCI#1调度的业务发生资源冲突时,如果DCI#1调度的业务与DCI#2调度的业务之间发生非顺序传输时,此时,通过根据是否执行DCI#1的调度确定是否恢复执行信令#1的调度,从而在确定恢复执行信令#1的调度时满足信令#1所调度的业务的性能需求。
下面以终端设备作为执行主体为例,对本申请实施例提供的无线通信的方法200分场景进行详细描述。其中,网络设备作为执行主体时,其对应的技术方案可以参考下文中场景#1与场景#2中的相关描述,为了简洁,后文中不再赘述。
场景#1单载波场景
如图6所示,终端设备首先接收到信令#1指示终端设备在时域资源#1(例如,slot#(n+3)的符号#6~符号#13)上接收信息#1;然后,终端设备在slot#n的符号#1与符号#2上接收到了DCI#1,DCI#1指示终端设备在时域资源#2(例如,slot#(n+3)的符号#0~符号#8)上发送信息#2。其中,slot#(n+3)中的符号被配置为了灵活符号。
终端设备在slot#(n+1)的符号#1与符号#2上接收到了DCI#2,DCI#2指示终端设备在时域资源#3(例如,slot#(n+2)的符号#0~符号#13与slot#(n+3)的符号#0~符号#1)上发送信息#3。
可以看出,信令#1调度的资源与DCI#1调度的资源发生了重叠现象,其中,重叠的资源为时域资源#4(例如,slot#(n+3)中的符号#6~符号#8)。此时,终端设备通常会取消执行信令#1的调度,转而执行DCI#1的调度。
还可以看出,DCI#2与DCI#1之间的调度发生了非顺序传输。在这种情况下,终端设备可以进一步确定是否要执行DCI#1的调度,并且可以根据是否执行DCI#1的调度,确定是否恢复执行信令#1的调度。
终端设备可以通过以下几种方式确定是否执行DCI#1的调度。
方式#1
当发生非顺序传输时,终端设备则取消执行DCI#1的调度。
需要说明的是,当DCI#1与DCI#2之间的调度为顺序传输时,如果DCI#1调度的时域资源与DCI#2调度的时域资源之间发生重叠时,终端设备也可以取消执行DCI#1的调度或者取消执行DCI#2调度。
方式#2
终端设备可以根据DCI#1与DCI#2分别调度的业务的优先级,确定是否执行DCI#1的调度。如果DCI#1的调度的业务的优先级低于DCI#2调度的业务的优先级时,终端设备确定取消执行DCI#1的调度。
终端设备可以通过以下方法判断业务的优先级:
(1)根据DCI的起始时刻,确定业务的优先级,例如,起始时刻较晚的DCI的优先级较高。
(2)根据物理层信令的指示,确定DCI所调度的业务的类型,并根据业务的类型,确定业务的优先级,其中,物理层信令是DCI中的一个字段。例如,在物理层信令中可以增加若干比特来指示DCI所调度的业务的类型,终端设备根据DCI所调度的业务的类型,确定业务的优先级。例如,通常认为增强型移动宽带(enhanced mobile broadband,eMBB)业务的优先级低于高可靠低时延通信(ultra-reliable and low-latency communications,URLLC)业务的优先级。
(3)以eMBB业务与URLLC业务为例进行说明。在配置eMBB业务与URLLC业务的搜索空间时,保证其各自的搜索空间不重叠,终端设备在为eMBB业务配置的搜索空间中检测到的DCI即用于调度eMBB业务(即,低优先级业务),在为URLLC业务配置的搜索空间中检测到的DCI即用于调度URLLC业务(即,高优先级业务)。
此外,以DCI#2与DCI#1为例进行说明。终端设备还可以根据时域资源#3的结束时刻与时域资源#2的起始时刻之间的时间间隔,确定是否执行DCI#1的调度。例如,当时域资源#3的结束时刻与时域资源#2的起始时刻之间的符号数小于或等于5时,确定取消执行DCI#1的调度。
当终端设备确定取消执行DCI#1的调度时,便不存在DCI#1调度的资源与信令#1调度的资源存在资源重叠的情况,此时,终端设备可以确定是否恢复执行信令#1的调度。
终端设备可以通过以下几种方法确定是否恢复执行信令#1的调度。
方法#1
当终端设备确定取消执行DCI#1的调度,即终端设备确定在时域资源#2上不发送信息#2时,则确定恢复执行信令#1的调度,即确定在时域资源#1上接收信息#1;或者,当终端设备确定执行DCI#1的调度,即终端设备确定在时域资源#2上发送信息#2时,则确定不恢复执行信令#1的调度,即在时域资源#1上不接收信息#1。
需要说明的是,在本申请实施例中,当终端设备确定取消执行DCI#1的调度时,此时,终端设备也可以不恢复执行信令#1的调度。后续为了简洁,不再进行赘述。
方法#2
在方法#1的基础上,当终端设备确定取消执行DCI#1的调度时,终端设备还可以进一步根据时域资源#3的结束时刻与时域资源#1的起始时刻的时间间隔与时间阈值#1(即,第一时间阈值的一例)的大小关系,确定是否恢复执行信令#1的调度。当时域资源#3的 结束时刻与时域资源#1的起始时刻的时间间隔大于或等于时间阈值#1时,终端设备确定恢复执行信令#1的调度。
如图6中的阶段#3所示,终端设备确定时域资源#3的结束时刻为slot#(n+3)中的符号#1。如图6中的阶段#1所示,时域资源#1的起始时刻为slot#(n+3)中的符号#6。时域资源#3的结束时刻与时域资源#1的起始时刻之间时间间隔为4个符号,假设时间阈值#1为1个符号,则终端设备确定执行信令#1的调度。
方法#3
在方法#1的基础上,当终端设备确定取消执行DCI#1的调度时,终端设备还可以进一步根据DCI#2的结束时刻与时域资源#1的起始时刻的时间间隔与时间阈值#2(即,第二时间阈值的一例)的大小关系,确定是否恢复执行信令#1的调度。当DCI#2的结束时刻与时域资源#1的起始时刻的时间间隔大于或等于时间阈值#2时,终端设备确定恢复执行信令#1的调度。
如图6中的阶段#3所示,终端设备确定DCI#2的结束时刻为slot#(n+1)中的符号#1。如图6中的阶段#1所示,时域资源#1的起始时刻为slot#(n+3)中的符号#6)。DCI#2的结束时刻与时域资源#1的起始时刻之间的时间间隔为32个符号,假设时间阈值#2为1个符号,则终端设备确定执行信令#1的调度。
需要说明的是,上述时间阈值#1、时间阈值#2可以是预设的,或者,可以是网络设备通过信令配置给终端设备的,本申请实施例对此不作特别限定。后面出现的时间阈值#3、时间阈值#4同此处对时间阈值#1、时间阈值#2的说明,为了简洁,后续不再赘述。
方法#4
在方法#1的基础上,当终端设备确定取消执行DCI#1的调度时,终端设备还可以进一步根据信息#1的具体内容,确定是否恢复执行信令#1的调度。
例如,当信息#1为信道状态信息参考信号(channel state information-reference signal,CSI-RS)或承载在PDSCH上的数据时,则终端设备确定执行或者不执行信令#1的调度。
场景#2多载波场景,以包括载波#1与载波#2的两个载波的场景为例进行说明。
如图7所示,终端设备接收到来自网络设备的信令#1,指示终端设备在载波#1上的时域资源#1(例如,slot#(n+3)的符号#6~符号#13)上接收信息#1。终端设备在载波#1上的slot#n的符号#1与符号#2上接收到了DCI#1,DCI#1指示终端设备在载波#1上的时域资源#2(例如,slot#(n+3)的符号#0~符号#8)上发送信息#2。其中,slot#(n+3)中的符号被配置为了灵活符号。终端设备在载波#2上的slot#(n+1)的符号#1与符号#2上接收到了DCI#2,DCI#2指示终端设备在载波#2上的时域资源#3(例如,slot#(n+2)的符号#0~符号#13与slot#(n+3)的符号#0~符号#1)上发送信息#3。
需要说明的是,上述仅作为示例性说明,并不对本申请的实施例构成限定。在具体实现时,信令#1、DCI#1还可以承载在除载波#1外的其他载波上,DCI#2还可以承载在除载波#2外的其他载波上;进一步地,信令#1、DCI#1与DCI#2中的至少两个可以承载在同一载波上,或者,各自承载在不同载波上。
可以看出,信令#1调度的时域资源与DCI#1调度的时域资源发生了重叠现象,其中,重叠的资源为时域资源#4(例如,slot#(n+3)中的符号#6~符号#8)。此时,终端设备通常会取消执行信令#1的调度,转而执行DCI#1的调度。
还可以看出,DCI#2与DCI#1之间的调度发生了非顺序传输。在这种情况下,终端设备可以进一步确定是否要执行DCI#1的调度,并且可以根据是否执行DCI#1的调度,确定是否恢复执行信令#1的调度。关于终端设备确定是否执行DCI#1的调度的方法请参考场景#1中的相关描述,为了简洁,此处不再赘述。
当终端设备确定取消执行DCI#1的调度时,便不存在DCI#1调度的资源与信令#1调度的资源存在资源重叠的情况,此时,终端设备可以确定是否恢复执行信令#1的调度。
终端设备可以通过以下几种方法确定是否恢复执行信令#1的调度。
方法#1
在场景#1中的方法#1的基础上,终端设备除了根据是否取消执行DCI#1的调度,从而确定是否恢复执行信令#1的调度以外,还需要在确定取消执行DCI#1的调度后,进一步确定除载波#1以外的其他载波上的时域资源#1是否与载波#1上的时域资源#1的传输方向一致,当除载波#1以外的其他载波上的时域资源#1与载波#1上的时域资源#1的传输方向一致时,终端设备才可以确定恢复执行信令#1的调度。
例如,载波#1与载波#2为被终端设备激活的用于与网络设备进行通信的两个载波,当终端设备确定取消在载波#1上执行DCI#1的调度后,由于信令#1指示终端设备在载波#1上的slot#(n+3)的符号#6~符号#13上接收信息#1,终端设备在确定是否恢复执行信令#1的调度时,还需要确定除载波#1外的载波#2上的slot#(n+3)的符号#6~符号#13是否被配置为下行传输资源。换句话说,只有当载波#2上的slot#(n+3)的符号#6~符号#13没有被配置为上行传输资源时,终端设备才可以恢复执行信令#1的调度。
例如,如图7所示,终端设备在载波#2上的slot#(n+1)的符号#12与符号#13上接收到了DCI#3,DCI#3指示终端设备在载波#2上的slot#(n+3)上接收信息#4,终端设备可以确定载波#2上的slot#(n+3)的符号#6~符号#13没有被配置为上行传输资源,则终端设备可以恢复执行信令#1的调度。
方法#2
在场景#2的方法#1的基础上,当终端设备确定载波#2上的slot#(n+3)的符号#6~符号#13没有被配置为上行传输资源时,终端设备还可以进一步根据时域资源#3的结束时刻与时域资源#1的起始时刻的时间间隔与时间阈值#1的大小关系,确定是否恢复执行信令#1的调度。当时域资源#3的结束时刻与时域资源#1的起始时刻的时间间隔大于或等于时间阈值#1时,终端设备确定恢复执行信令#1的调度。更具体的描述,可以参考场景#1中的方法#2的相关描述。
方法#3
在场景#2的方法#1的基础上,当终端设备确定载波#2上的slot#(n+3)的符号#6~符号#13没有被配置为上行传输资源时,终端设备还可以进一步根据DCI#2的结束时刻与时域资源#1的起始时刻的时间间隔与时间阈值#2的大小关系,确定是否恢复执行信令#1的调度,当DCI#2的结束时刻与时域资源#1的起始时刻的时间间隔大于或等于时间阈值#2时,终端设备确定恢复执行信令#1的调度。更具体的描述,可以参考场景#1中的方法#3的相关描述。
方法#4
在场景#2的方法#1的基础上,当终端设备确定载波#2上的slot#(n+3)的符号#6~ 符号#13没有被配置为上行传输资源时,终端设备还可以进一步根据信息#1的具体内容,确定是否恢复执行信令#1的调度。
例如,当信息#1为信道状态信息参考信号CSI-RS或承载在物理下行共享信道PDSCH上的数据时,则终端设备确定执行信令#1的调度。
还需要说明的是,方法200中提到的终端设备确定是否恢复执行高层信令的调度的方法可以是与网络设备协商好的,或者,也可以是网络设备向终端设备指示的,本申请实施例对此不作特别限定。此处的说明同样适用于方法300,为了简洁,后续不再赘述。
还需要说明的是,方法200中的场景#2同样适用于一个载波同时被激活至少两个BWP的场景。此处的说明同样适用于方法300中的场景#2,为了简洁,后续不再赘述。
上述方法200中的第一信令用于调度下行业务数据,第一DCI、第二DCI分别用于调度上行业务数据。本申请针对第一信令用于调度上行业务数据,第一DCI、第二DCI分别用于调度下行业务数据的情况,还提供了方法300。图8是本申请实施例提供的无线通信的方法300的示意***互图。下面,对方法300的每个步骤进行详细说明。
在本申请实施例中,以终端设备和网络设备作为执行方法300的执行主体为例,对方法300进行说明。作为示例而非限定,执行方法300的执行主体也可以是对应终端设备的芯片和对应网络设备的芯片。
在S310中,网络设备向终端设备发送信令#2(即,第一信令的一例),信令#2指示终端设备在时域资源#5(即,第一时域资源的一例)上发送信息#5(即,第一信息的一例),。相应地,终端设备接收来自网络设备的信令#1。
也就是说,网络设备通过信令#2通知终端设备在时域资源#5上发送信息#5,其中,信令#4可以是高层信令。
例如,网络设备通过RRC信令向终端设备指示SPS资源,并向终端设备发送SPS资源的激活命令,使得终端设备能够使用激活态的SPS资源接收或者发送数据,其中,激活态的SPS资源包括时域资源#5。
在S320中,网络设备向终端设备发送DCI#4(即,第一DCI的一例),DCI#4指示终端设备在时域资源#6(即,第二时域资源的一例)上接收信息#6(即,第二信息的一例),,时域资源#5与时域资源#6在时域资源#7(即,第四时域资源的一例)上重叠,也称为时域资源#5与时域资源#6存在重叠,时域资源#7上的部分或者全部符号被配置为灵活符号。相应地,终端设备接收来自网络设备的DCI#4。
通常认为DCI的优先级高于高层信令的优先级,因此,当时域资源#5与时域资源#6发生重叠时,终端设备可以取消执行信令#2的调度,转而执行DCI#4的调度。
在S330中,网络设备向终端设备发送DCI#5(即,第二DCI的一例),DCI#5指示终端设备在时域资源#8(即,第三时域资源的一例)上接收信息#7(即,第三信息的一例),DCI#5的起始时刻晚于DCI#4的起始时刻,时域资源#8的起始时刻早于时域资源#6的起始时刻。相应地,终端设备接收来自网络设备发送的DCI#5。
终端设备接收到DCI#5,由于DCI#5的起始时刻晚于DCI#4的起始时刻,并且时域资源#8的起始时刻早于时域资源#6的起始时刻,参考前面对非顺序传输的介绍,可以看出,DCI#5与DCI#4之间的调度发生了非顺序传输。
在S340中,终端设备根据是否在时域资源#6上接收信息#6,确定是否在时域资源#5 上发送信息#5。
鉴于DCI#5与DCI#4之间的调度发生了非顺序传输,终端设备可以确定是否要执行DCI#5的调度,即确定是否要在时域资源#6上接收信息#6,根据确定结果,确定是否恢复执行信令#2的调度,即确定是否在时域资源#5上发送信息#5。
相应地,此时方法300还可以包括S350,网络设备可以根据是否在时域资源#6上发送信息#6,确定是否在时域资源#5上接收信息#5。
鉴于DCI#5与DCI#4之间的调度发生了非顺序传输,网络设备可以确定是否要在时域资源#6上发送信息#6,根据确定结果,确定是否在时域资源#5上接收信息#5。
需要说明的是,在S340与S350中,终端设备与网络设备各自得到的确定结果是相一致的,例如,当网络设备确定不在时域资源#6上发送信息#6时,相应地,终端设备会确定不在时域资源#6上接收信息#6;当网络设备确定在时域资源#6上发送信息#6时,相应地,终端设备会确定在时域资源#6上接收信息#6。
例如,当终端设备确定在时域资源#5上发送信息#5时,相应地,网络设备会确定在时域资源#5上接收信息#5;当终端设备确定不在时域资源#5上发送信息#5时,相应地,网络设备会确定不在时域资源#5上接收信息#5。
下面以终端设备作为执行主体为例,对本申请实施例提供的无线通信的方法300分场景进行详细描述。其中,网络设备作为执行主体时,其对应的技术方案可以参考下文中场景#1与场景#2中的相关描述,为了简洁,后文中不再赘述。
场景#1单载波场景
如图9所示,终端设备首先接收到信令#2指示终端设备在时域资源#5(例如,slot#(n+3)的符号#4~符号#11)上发送信息#5;然后,终端设备在slot#n的符号#1与符号#2上接收到了DCI#4,DCI#4指示终端设备在时域资源#6(例如,slot#(n+3)的符号#0~符号#6)上接收信息#6。其中,slot#(n+3)中的符号被配置为了灵活符号。
终端设备在slot#(n+1)的符号#1与符号#2上接收到了DCI#5,DCI#5指示终端设备在时域资源#8(例如,slot#(n+2)的符号#0~符号#13与slot#(n+3)的符号#0~符号#3)上接收信息#7。
可以看出,信令#2调度的资源与DCI#4调度的资源发生了重叠现象,其中,重叠的资源为时域资源#7(例如,slot#(n+3)中的符号#4~符号#6)。此时,终端设备通常会取消执行信令#2的调度,转而执行DCI#4的调度。
还可以看出,DCI#4与DCI#5之间的调度发生了非顺序传输。在这种情况下,终端设备可以进一步确定是否要执行DCI#4的调度,并且可以根据是否执行DCI#4的调度,确定是否恢复执行信令#2的调度。关于终端设备确定是否执行DCI#4的调度的方法请参考方法200中的相关描述,为了简洁,此处不再赘述。
当终端设备确定取消执行DCI#4的调度时,便不存在与信令#2调度的资源存在资源重叠的情况,此时,终端设备可以确定是否恢复执行信令#2的调度。
终端设备可以通过以下几种方法确定是否恢复执行信令#2的调度。
方法#1
当终端设备确定取消执行DCI#4的调度,即终端设备确定在时域资源#6上不接收信息#6时,则确定恢复执行信令#2的调度,即确定在时域资源#5上发送信息#5;或者,当 终端设备确定执行DCI#4的调度,即终端设备确定在时域资源#6上接收信息#6时,则确定不恢复执行信令#2的调度,即在时域资源#5上不发送信息#5。
方法#2
在方法#1的基础上,当终端设备确定取消执行DCI#4的调度时,终端设备还可以进一步根据时域资源#8的结束时刻与时域资源#5的起始时刻的时间间隔与时间阈值#3(即,第三时间阈值的一例)的大小关系,确定是否恢复执行信令#2的调度,当时域资源#8的结束时刻与时域资源#5的起始时刻的时间间隔大于或等于时间阈值#3时,终端设备确定恢复执行信令#2的调度。
如图9中的阶段#3所示,终端设备确定时域资源#8的结束时刻为slot#(n+3)中的符号#3。如图9中的阶段#1所示,时域资源#5的起始时刻为slot#(n+3)中的符号#4。时域资源#8的起始时刻与时域资源#5的起始时刻之间的时间间隔为0个符号,假设时间阈值#3为Y个符号(Y为大于或等于1的整数,例如,Y的取值为1),则终端设备确定不执行信令#2的调度。
需要说明的是,Y的取值和射频切换时间长度相关,例如,Y的取值不小于射频切换时间长度,或者,Y的取值和时间提前量(timing advance,TA)相关,例如,Y的取值不小于TA时长),或者,Y的取值和TA及射频切换时间长度相关,即Y的取值不小于TA与射频切换时间长度的总和。
上述TA是指终端设备发送信息#5时的时间提前量,可以由网络设备向终端设备指示,射频切换时间长度是终端设备切换射频时需要的时间长度,该时间长度可以基于协议确定。
方法#3
在方法#1的基础上,当终端设备确定取消执行DCI#4的调度时,终端设备还可以进一步根据DCI#5的结束时刻与时域资源#5的起始时刻的时间间隔与时间阈值#4(即,第四时间阈值的一例)的大小关系,确定是否恢复执行信令#2的调度,当DCI#5的结束时刻与时域资源#5的起始时刻的时间间隔大于或等于时间阈值#4时,终端设备确定恢复执行信令#2的调度。
如图9中的阶段#3所示,终端设备确定DCI#5的结束时刻为slot#(n+1)中的符号#1。如图9中的阶段#1所示,时域资源#5的起始时刻为slot#(n+3)中的符号#4。DCI#5的结束时刻与时域资源#5的起始时刻之间的时间间隔为30个符号,假设时间阈值#4为X个符号(X为大于或等于1的整数,例如,X的取值为13),则终端设备确定执行信令#2的调度。
上述时间阀值#4的取值和终端设备进行上行发送时的准备时间T相关,T和终端设备上报的处理能力N
2相关。终端设备对于PUSCH处理能力可以如下表所示:
表1:对于PUSCH处理能力1
表2:对于PUSCH处理能力2
方法#4
在方法#1的基础上,当终端设备确定取消执行DCI#4的调度时,终端设备还可以进一步根据信息#5的具体内容,确定是否恢复执行信令#2的调度。
例如,当信息#5包括承载在物理随机接入信道(physical random access channel,PRACH)上的数据、承载在PUSCH上的数据、上行控制信息(uplink control information,UCI)与探测参考信号(sounding reference signal,SRS)中的任意一种时,则终端设备确定执行信令#1的调度。
场景#2多载波场景(以包括两个载波(例如,载波#1与载波#2)的场景为例进行说明)
如图10所示,终端设备在载波#1上接收到来自网络设备的信令#2,指示终端设备在载波#1上的时域资源#5(例如,slot#(n+3)的符号#4~符号#11)上发送信息#5。终端设备在载波#1上的slot#n的符号#1与符号#2上接收到了DCI#4,DCI#4指示终端设备在载波#1上的时域资源#6(例如,slot#(n+3)的符号#0~符号#6)上接收信息#6。其中,slot#(n+3)中的符号被配置为了灵活符号。
终端设备在载波#2上的slot#(n+1)的符号#1与符号#2上接收到了DCI#5,DCI#5指示终端设备在载波#2上的时域资源#8(例如,slot#(n+2)的符号#0~符号#13与slot#(n+3)的符号#0~符号#3)上发送信息#7。
需要说明的是,上述仅作为示例性说明,并不对本申请的实施例构成限定。在具体实现时,信令#2、DCI#4还可以承载在除载波#1外的其他载波上,DCI#5还可以承载在除载波#2外的其他载波上;进一步地,信令#2、DCI#4与DCI#5中的至少两个可以承载在同一载波上,或者,各自承载在不同载波上。
可以看出,信令#2调度的时域资源与DCI#4调度的时域资源发生了重叠现象,其中,重叠的资源为时域资源#7(例如,slot#(n+3)中的符号#4~符号#6)。此时,终端设备通常会取消执行信令#2的调度,转而执行DCI#4的调度。
还可以看出,DCI#4与DCI#5之间的调度发生了非顺序传输。在这种情况下,终端设备可以进一步确定是否要执行DCI#4的调度,并且可以根据是否执行DCI#4的调度,确定是否恢复执行信令#2的调度。关于终端设备确定是否执行DCI#4的调度的方法请参考 方法200中的相关描述,为了简洁,此处不再赘述。
当终端设备确定取消执行DCI#4的调度时,便不存在DCI#4调度的资源与信令#2调度的资源存在资源重叠的情况,此时,终端设备可以确定是否恢复执行信令#2的调度。
终端设备可以通过以下几种方法确定是否恢复执行信令#2的调度。
方法#1
在场景#1中的方法#1的基础上,终端设备除了根据是否取消执行DCI#4的调度,从而确定是否恢复执行信令#2的调度以外,还需要在确定取消执行DCI#4的调度后,进一步确定除载波#1以外的其他载波上的时域资源#5是否与载波#1上的时域资源#5的传输方向一致,当除载波#1以外的其他载波上的时域资源#5与载波#1上的时域资源#5的传输方向一致时,终端设备才可以确定恢复执行信令#2的调度。
例如,载波#1与载波#2为被终端设备激活的用于与网络设备进行通信的两个载波,当终端设备确定取消在载波#1上执行DCI#4的调度后,由于信令#2指示终端设备在载波#1上的slot#(n+3)的符号#4~符号#11上发送信息#5,终端设备在确定是否恢复执行信令#2的调度时,还需要确定除载波#1外的载波#2上的slot#(n+3)的符号#4~符号#11是否被配置为上行传输资源。换句话说,只有当载波#2上的slot#(n+3)的符号#4~符号#11没有被配置为下行传输资源时,终端设备才可以恢复执行信令#2的调度。
例如,如图10所示,终端设备在载波#2上的slot#(n+1)的符号#12与符号#13上接收到了DCI#6,DCI#6指示终端设备在载波#2上的slot#(n+3)上发送信息#8,终端设备可以确定载波#2上的slot#(n+3)的符号#6~符号#13没有被配置为下行传输资源,则终端设备可以恢复执行信令#2的调度。
方法#2
在场景#2的方法#1的基础上,当终端设备确定载波#2上的slot#(n+3)的符号#6~符号#13没有被配置为下行传输资源时,终端设备还可以进一步根据时域资源#8的结束时刻与时域资源#5的起始时刻的时间间隔与时间阈值#3的大小关系,确定是否恢复执行信令#2的调度,当时域资源#8的结束时刻与时域资源#5的起始时刻的时间间隔大于或等于时间阈值#3时,终端设备确定恢复执行信令#2的调度。更具体的描述,可以参考场景#1中的方法#2的相关描述。
方法#3
在场景#2的方法#1的基础上,当终端设备确定载波#2上的slot#(n+3)的符号#6~符号#13没有被配置为下行传输资源时,终端设备还可以进一步根据DCI#5的结束时刻与时域资源#5的起始时刻的时间间隔与时间阈值#4的大小关系,确定是否恢复执行信令#2的调度,当DCI#5的结束时刻与时域资源#5的起始时刻的时间间隔大于或等于时间阈值#2时,终端设备确定恢复执行信令#1的调度。更具体的描述,可以参考场景#1中的方法#3的相关描述。
方法#4
在场景#2的方法#1的基础上,当终端设备确定载波#2上的slot#(n+3)的符号#6~符号#13没有被配置为下行传输资源时,终端设备还可以进一步根据信息#5的具体内容,确定是否恢复执行信令#2的调度。
例如,当信息#5包括承载在PRACH上的数据、承载在PUSCH上的数据、UCI与SRS 中的任意一种时,则终端设备确定执行信令#1的调度。
