Description

一种通信方法及装置
本申请要求于2018年08月07日提交国家知识产权局、申请号为201810893348.6、申请名称为“一种通信方法及装置”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
本申请涉及通信技术领域,尤其涉及一种通信方法及装置。
背景技术
在5G新空口(New Radio,NR)技术中,终端设备和网络设备除了可以使用一个时分双工(Time Division Duplex,TDD)载波进行上、下行通信之外,还可以使用多个额外的上行载波进行上行通信,该额外的上行载波通常被称为上行增补(Supplementary Uplink,SUL)载波,并且SUL载波的载波频率不等于TDD载波频率,即终端设备和网络设备之间可以同时拥有多个可用的上行载波进行上行通信,并且多个上行载波对应于一个下行载波。
在现有技术中,考虑到终端设备的能力和发射功率等因素,在同一时间段内,终端设备只在多个上行载波中的一个载波上向网络设备发送上行信号,也可称为上行单发。但是终端设备可以在不同的上行载波上进行切换,例如,在第一时间段内在TDD载波上发送上行信号,在第二时间段内则在一个SUL载波上发送上行信号。对于终端设备在不同上行载波上进行切换的情况,如果终端设备在两个上行载波上使用了同一个射频回路,并且两个上行载波的频率相差较大,则终端设备需要一定的转换时间来实现两个上行载波间的切换。通常终端设备会丢弃前一个载波上的最后一个或者多个符号,或者丢弃后一个载波上的第一个或者前几个符号,从而可以在被丢弃的符号所占用的时间中完成射频回路的工作频率的调整。如果丢弃后一个载波上的第一个或者前几个符号,而后一个载波上的上行信号为物理上行共享信道(Physical-layer Uplink Shared Channel,PUSCH),且解调参考信号(Demodulation Reference Signal,DMRS)配置在PUSCH的第一个符号,则DMRS被丢弃,将会导致网络设备接收不到DMRS,无法进行信道估计而无法对PUSCH进行正确解调,即PUSCH传输失败。

本申请提供的技术方案可以应用于包括上行载波切换场景的各种通信系统,例如当前5G NR系统,未来演进系统或者多种通信融合系统等等。可以包括多种应用场景,可以包括机器对机器(Machine to Machine,M2M)、D2M、宏微通信、增强型移动互联网(enhance Mobile Broadband,eMBB)、超高可靠性与超低时延通信(ultra Reliable&Low Latency Communication,uRLLC)以及海量物联网通信(massive Machine Type Communication,mMTC)等场景,这些场景可以包括但不限于:终端设备与终端设备之间的通信场景,网络设备与网络设备之间的通信场景,网络设备与终端设备之间的通 信场景等。
本申请实施例提供的技术方案可以应用于如图1所示的系统架构中,该系统架构中可以包括网络设备100以及与网络设备100连接的一个或多个终端设备200。
网络设备100可以是能和终端设备200通信的设备。网络设备100可以是宽带码分多址(Wideband Code Division Multiple Access,WCDMA)中的NB(NodeB),还可以是长期演进(Long Term Evolution,LTE)中的eNB或eNodeB(evolutional NodeB),还可以是5G移动通信系统中的节点,其中,5G节点可以为:接入节点、下一代基站(generation NodeB,gNB)、收发点(Transmission Receive Point,TRP)、传输点(Transmission Point,TP)或某种其它接入节点。网络设备100还可以是云无线接入网络(Cloud Radio Access Network,CRAN)场景下的无线控制器,还可以是未来演进的PLMN网络中的网络设备或中继站或接入点,还可以是可穿戴设备或车载设备等。
终端设备200可以是接入终端、用户设备(User Equipment,UE)单元、UE站、移动站、移动台、远方站、远程终端、移动设备、UE终端、终端、无线通信设备、UE代理、UE装置、虚拟现实终端设备、增强现实终端设备或工业控制中的无线终端等。接入终端可以是蜂窝电话、无绳电话、会话启动协议(Session Initiation Protocol,SIP)电话、无线本地环路(Wireless Local Loop,WLL)站、个人数字处理(Personal Digital Assistant,PDA)、具有无线通信功能的手持设备、计算设备或连接到无线调制解调器的其它处理设备、车载设备、可穿戴设备,5G网络中的终端或未来演进的PLMN网络中的终端等。
其中,终端设备200和网络设备100之间可以通过一个TDD载波进行上、下行通信,还可以使用至少一个SUL载波进行上行通信;即网络设备和终端设备可以同时拥有两个或两个以上的上行载波进行上行通信,并且这两个或两个以上的上行载波对应于一个下行载波。终端设备200和网络设备100之间的两个或两个以上的上行载波的载波频率互不相同。需要说明的是,SUL载波可以是NR系统独立使用的载波,也可以是NR系统与LTE系统共享的上行载波。终端设备200发送上行信号时,可以在TDD载波和至少一个SUL载波上进行切换。
应注意,图1所示的系统架构仅用于举例,并非用于限制本申请的技术方案。本领域的技术人员应当明白,在具体实现过程中,该系统架构中还可能包括其他设备,比如核心网设备,同时也可根据具体需要来配置网络设备100和终端设备200的数量。
本申请实施例提供的通信方法和装置,可以应用于终端设备中,该终端设备包括硬件层、运行在硬件层之上的操作系统层,以及运行在操作系统层上的应用层。该硬件层包括中央处理器(Central Processing Unit,CPU)、内存管理单元(Memory Management Unit,MMU)和内存(也称为主存)等硬件。该操作系统可以是任意一种或多种通过进程(process)实现业务处理的计算机操作系统,例如,Linux操作系统、Unix操作系统、Android操作系统、iOS操作系统或windows操作系统等。该应用层包含浏览器、通讯录、文字处理软件、以及即时通信软件等应用。并且,在本申请实施例中,通信方法的执行主体的具体结构,本申请实施例并未特别限定,只要能够通过运行记录有本申请实施例的通信方法的代码的程序,以根据本申请实施例的通信方法进行通信即可,例如,本申请实施例提供的通信方法的执行主体可以是终端设备, 或者,是终端设备中能够调用程序并执行程序的功能模块,或者为应用于终端设备中通信装置,例如,芯片,本申请对此不作限定。
此外,本申请实施例的各个方面或特征可以实现成方法、装置或使用标准编程和/或工程技术的制品。本申请中使用的术语“制品”涵盖可从任何计算机可读器件、载体或介质访问的计算机程序。例如,计算机可读介质可以包括,但不限于:磁存储器件(例如,硬盘、软盘或磁带等),光盘(例如,压缩盘(Compact Disc,CD)、数字通用盘(Digital Versatile Disc,DVD)等),智能卡和闪存器件(例如,可擦写可编程只读存储器(Erasable Programmable Read-Only Memory,EPROM)、卡、棒或钥匙驱动器等)。另外,本文描述的各种存储介质可代表用于存储信息的一个或多个设备和/或其它机器可读介质。术语“机器可读介质”可包括但不限于,无线信道和能够存储、包含和/或承载指令和/或数据的各种其它介质。
由于未来接入网可以采用云无线接入网(Cloud Radio Access Network,C-RAN)架构来实现,一种可能的方式是将传统基站的协议栈架构和功能分割为两部分,一部分称为集中单元(Central Unit,CU),另一部分称为分布单元(Distributed Unit,DU),而CU和DU的实际部署方式比较灵活,例如多个基站的CU部分集成在一起,组成一个规模较大的功能实体。如图2所示,其为本申请实施例提供的一种网络架构的示意图。如图2所示,该网络架构包括接入网(以无线接入网(Radio Access Network,RAN)为例)设备和终端设备。其中RAN设备包括基带装置和射频装置,其中基带装置可以由一个节点实现,也可以由多个节点实现,射频装置可以从基带装置拉远独立实现,也可以集成基带装置中,或者部分拉远部分集成在基带装置中。例如,在LTE通信系统中,RAN设备(eNB)包括基带装置和射频装置,其中射频装置可以相对于基带装置拉远布置(例如射频拉远单元(Radio Remote Unit,RRU)相对于基带处理单元(Building Baseband Unit,BBU)),RAN设备由一个节点实现,该节点用于实现无线资源控制(Radio Resource Control,RRC)、分组数据汇聚层协议(Packet Data Convergence Protocol,PDCP)、无线链路控制(Radio Link Control,RLC)、媒体接入控制(Media Access Control,MAC)等协议层的功能。再如,在一种演进结构中,基带装置可以包括CU和DU,多个DU可以由一个CU集中控制。如图2所示,CU和DU可以根据无线网络的协议层划分,例如分组数据汇聚层协议层及以上协议层的功能设置在CU,PDCP以下的协议层,例如RLC和MAC层等的功能设置在DU。
这种协议层的划分仅仅是一种举例,还可以在其它协议层划分,例如在RLC层划分,将RLC层及以上协议层的功能设置在CU,RLC层以下协议层的功能设置在DU;或者,在某个协议层中划分,例如将RLC层的部分功能和RLC层以上的协议层的功能设置在CU,将RLC层的剩余功能和RLC层以下的协议层的功能设置在DU。此外,也可以按其它方式划分,例如按时延划分,将处理时间需要满足时延要求的功能设置在DU,不需要满足该时延要求的功能设置在CU。
此外,射频装置可以拉远,不放在DU中,也可以集成在DU中,或者部分拉远部分集成在DU中,在此不作任何限制。
此外,请继续参考图3,相对于图2所示的架构,还可以将CU的控制面(Control Plane,CP)和用户面(User Plane,UP)分离,分成不同实体来实现,分别为控制面 CU实体(CU-CP实体)和用户面CU实体(CU-UP实体)。
在以上网络架构中,CU产生的信令/数据可以通过DU发送给终端设备,或者终端设备产生的信令/数据可以通过DU发送给CU。DU可以不对该信令/数据进行解析而直接通过协议层封装而透传给终端设备或CU。以下实施例中如果涉及这种信令/数据在DU和终端设备之间的传输,此时,DU对信令/数据的发送或接收包括这种场景。例如,RRC或PDCP层的信令最终会处理为物理层(physical layer,PHY)的信令/数据发送给终端设备,或者,由接收到的PHY层的信令/数据转变而来。在这种架构下,该RRC或PDCP层的信令/数据,即也可以认为是由DU发送的,或者,由DU和射频发送的。
在以上实施例中CU划分为RAN中网络设备,此外,也可以将CU划分为核心网中的网络设备,在此不做限制。
本申请以下实施例中的装置,根据其实现的功能,可以位于终端设备或网络设备。当采用以上CU-DU的结构时,网络设备可以为CU节点、或DU节点、或包括CU节点和DU节点功能的RAN设备。
在本申请中,执行上述通信方法的可以是网络设备和终端设备,也可以是应用于网络设备和终端设备中的装置,例如,芯片,或者其他实现上述通信方法的装置,本申请实施例对此不进行限定。本文中以网络设备和终端设备执行上述通信方法为例进行说明。
下面对本申请中涉及的部分术语进行解释说明:
1、上行信号
终端设备向网络设备发送的上行信号可以包括数据信号、控制信号、前导序列信号和测量信号,数据信号承载在物理上行共享信道(Physical-layer Uplink Shared Channel,PUSCH)上,控制信号(上行控制信息(Uplink Control Information,UCI))承载在物理上行控制信道(Physical-layer Uplink Control Channel,PUCCH)上,前导序列信号承载在物理随机接入信道(Physical-layer Random Access Channel,PRACH),测量信号包括探测参考信号(Sounding Reference Signal,SRS)。具体的,UCI中可以包括应答反馈信息(即ACK/NACK),信道状态信息(Channel State Information,CSI)等。
2、参考信号配置方式
终端设备向网络设备发送PUSCH时还同时传输解调参考信号(Demodulation Reference Signal,DMRS),其中,参考信号配置方式可以包括:
第一参考信号配置方式:DMRS配置在PUSCH的第一个符号上。比如,第一参考信号配置方式可以为NR系统中的Type B PUSCH。
第二参考信号配置方式:DMRS配置在PUSCH的除第一个符号外的符号上。比如,第二参考信号配置方式可以为NR系统中的Type A PUSCH,DMRS配置在PUSCH的第三个符号或第四个符号上,或者DMRS配置在一个时隙的第三个符号或第四个符号上。
此外,PUSCH中还可以包括额外的DMRS,额外的DMRS为除第一参考信号配置方式和第二参考信号配置方式之外,配置在PUSCH中其他符号位置上的DMRS。
3、本文中的术语“多个”是指两个或两个以上。本文中的术语“第一”和“第二”是用于区别不同的对象,而不是用于描述对象的特定顺序。例如,第一时间段和第二 时间段仅仅是为了区分不同的时间段,并不对其先后顺序进行限定。本文中术语“和/或”,仅仅是一种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。
在本申请实施例中,“示例性的”或者“例如”等词用于表示作例子、例证或说明。本申请实施例中被描述为“示例性的”或者“例如”的任何实施例或设计方案不应被解释为比其它实施例或设计方案更优选或更具优势。确切而言,使用“示例性的”或者“例如”等词旨在以具体方式呈现相关概念。
终端设备和网络设备间存在多个上行载波,终端设备向网络设备发送上行信号时可以在不同上行载波上进行切换,如果终端设备在两个上行载波上使用了同一个射频回路,并且两个上行载波的载波频率相差较大,则终端设备需要一定的转换时间来实现两个上行载波间的切换,例如20微秒的时间,终端设备在共用一个射频回路的两个上行载波之间进行切换时,需要留出用于转换的时间。比如,终端设备可以丢弃一个或多个连续的符号,从而可以在被丢弃的符号所占用的时间中完成射频回路的工作频率的调整。示例性的,如图4所示,终端设备在第一时间段在上行载波1上向网络设备发送上行信号PUCCH,切换为在第二时间段在上行载波2上向网络设备发送上行信号PUSCH;可以丢弃前一个载波上的最后一个或多个连续的符号,或者丢弃后一个载波上的第一个或多个连续的符号,在被丢弃的符号所占用的时间中完成射频回路的工作频率的调整。选择丢弃前一个载波上的最后一个或多个连续的符号,或者丢弃后一个载波上的第一个或多个连续的符号,可以根据两个上行载波上发送上行信号的优先级来确定。例如,PRACH的优先级高于PUCCH,PUCCH的优先级高于PUSCH,PUSCH的优先级高于SRS。那么,如图4所示的情况,PUCCH的优先级高于PUSCH,可以丢弃PUSCH的第一个符号,PUSCH的第一个符号所占用的时间作为两个上行载波上切换的转换时间。如果参考信号配置方式为第一参考信号配置方式,即DMRS配置在PUSCH的第一个符号,则DMRS被丢弃,会导致网络设备接收不到DMRS,无法进行信道估计而无法对PUSCH进行正确解调,即PUSCH传输失败。
本申请实施例提供一种通信方法,可以应用于图1-图3所示的通信系统。在进行上行载波切换过程中,可以避免丢弃DMRS,保证PUSCH能够正确传输。如图5所示,该方法可以包括S101-S105:
S101、网络设备向终端设备发送第一指示信息和第二指示信息。
具体的,第一指示信息用于指示终端设备在第一时间段内在第一上行载波上发送第一信号,第二指示信息用于指示终端设备在第二时间段内在第二上行载波上发送第二信号。其中,第一时间段与第二时间段为时间上相邻的时间段,第一时间段在第二时间段之前,或者第一时间段在第二时间段之后。第一时间段与第二时间段的时长可以相等,也可以不相等,本申请实施例对此不进行限定。
示例性的,第一时间段和第二时间段可以是相邻的两个时隙。在NR系统中,一个时隙包括14个正交频分复用(Orthogonal Frequency Division Multiplexing,OFDM)符号,一个时隙的绝对时间长度与OFDM符号的子载波间隔相关,比如,15KHz子载波间隔对应的时隙长度为1ms,30KHz子载波间隔对应的时隙长度为0.5ms。
可选的,第一上行载波和第二上行载波为网络设备和终端设备之间的多个上行载 波中共用一个射频回路的任意两个上行载波。可选的,第一上行载波为图1中的TDD载波,第二上行载波为图1中的SUL载波。可选的,第一上行载波和第二上行载波可以是属于同一小区的两个上行载波,也可以是属于不同小区的上行载波,例如,第一上行载波和第二上行载波可以是采用载波聚合的两个上行载波,也可以是采用双连接的两个上行载波。
第一信号为第一上行载波上发送的上行信号,第二信号为第二上行载波上发送的上行信号。比如,第一信号为PUCCH,第二信号为PUSCH;比如,第一信号为PRACH,第二信号为PUSCH;第一信号和第二信号还可以是探测参考信号或其他类型的上行信号。本申请实施例中以第一信号为PUCCH,第二信号为PUSCH为例进行说明,本申请实施例并不限定第一信号与第二信号的类型。
示例性的,第一指示信息用于指示终端设备在第一时隙内在上行载波1上发送PUCCH,第二指示信息用于指示终端设备在第二时隙内在上行载波2上发送PUSCH。如果第一时间段在第二时间段之前,如图6a所示;如果第一时间段在第二时间段之后,如图6b所示。
在一种实现方式中,第一指示信息和第二指示信息可以携带在下行控制信息(Downlink Control Information,DCI)中由网络设备发送给终端设备。通常,第一指示信息携带在用于调度下行传输的DCI中,如NR系统中的DCI格式1_0或格式1_1,第二指示信息携带在用于调度上行传输的DCI中,如NR系统中的DCI格式0_0或格式0_1,也就是说,第一指示信息和第二指示信息分别携带在不同的消息中由网络设备发送给终端设备。需要说明的是,本申请实施例并不限定第一指示信息和第二指示信息分别携带在不同的消息中,第一指示信息和第二指示信息也可以携带在相同的消息中由网络设备发送给终端设备。
S102、终端设备接收第一指示信息和第二指示信息。
S103、终端设备确定被丢弃的符号。
在一种实现方式中,终端设备接收到第一指示信息和第二指示信息之后,根据第一指示信息确定第一时间段内在第一上行载波上待发送的第一信号,以及根据第二指示信息确定在第二时间段内在第二上行载波上待发送的第二信号。示例性的,终端设备确定在第一时隙内在上行载波1上发送PUCCH,以及确定在第二时隙内在上行载波2上发送PUSCH。如果第一时间段在第二时间段之前,如图6a所示,终端设备在第一时隙内在上行载波1上发送PUCCH,之后在第二时隙内在上行载波2上发送PUSCH;如果第一时间段在第二时间段之后,如图6b所示,终端设备在第二时隙内在上行载波2上发送PUSCH,之后在第一时隙内在上行载波1上发送PUCCH。
可选的,终端设备可以根据第一信号与第二信号的优先级确定被丢弃的符号。比如,可以根据第一信号与第二信号的优先级确定丢弃前一时间段的最后一个或多个连续的符号,或者丢弃后一时间段的第一个或前几个连续的符号。
在一种实现方式中,在第二信号采用第一参考信号配置方式的情况下,第二信号的优先级高于第一信号的优先级,终端设备确定第一信号中的第一符号被丢弃;在第二信号采用第二参考信号配置方式的情况下,第一信号的优先级高于第二信号的优先级,终端设备确定第二信号中的第二符号被丢弃。
示例性的,如图7a与图7b所示,第一信号为PUCCH,第二信号为PUSCH,第二信号采用第一参考信号配置方式,具体为DMRS配置在PUSCH的第一个符号上,则PUSCH的优先级高于PUCCH的优先级,终端设备确定PUCCH中的第一符号被丢弃。比如,在图7a中,确定被丢弃的符号为PUCCH在第一时隙中的最后一个符号,在图7b中,确定被丢弃的符号为PUCCH在第一时隙中的第一个符号。
示例性的,如图7c与图7d所示,第一信号为PUCCH,第二信号为PUSCH,第二信号采用第二参考信号配置方式,具体为DMRS配置在PUSCH的第三个符号或第四个符号上,以DMRS配置在PUSCH的第三个符号为例,PUCCH的优先级高于PUSCH的优先级,终端设备确定PUSCH中的第二符号被丢弃。比如,在图7c中,确定被丢弃的符号为PUSCH在第二时隙中的第一个符号,在图7d中,确定被丢弃的符号为PUSCH在第二时隙中的最后一个符号。
可以看出,在该实现方式中,确定为被丢弃的符号位置不包括配置了DMRS的位置。
在另一种实现方式中,若第一时间段在第二时间段之前,第二信号的优先级高于第一信号的优先级,终端设备确定第一信号中的第一符号被丢弃;若第一时间段在第二时间段之后,第一信号的优先级高于第二信号的优先级,终端设备确定第二信号中的第二符号被丢弃。
示例性的,如图7a与图7c'所示,第一信号为PUCCH,第二信号为PUSCH,第一时隙在第二时隙之前,PUSCH的优先级高于PUCCH的优先级,终端设备确定PUCCH在第一时隙中的最后一个符号被丢弃。
示例性的,如图7b'与图7d所示,第一时隙在第二时隙之后,PUCCH的优先级高于PUSCH的优先级,终端设备确定PUSCH在第二时隙中的最后一个符号被丢弃。
可以看出,在该实现方式中,确定为被丢弃的符号位置都不包括配置了DMRS的位置。
在另一种实现方式中,在第二信号采用第一参考信号配置方式的情况下,若第一时间段在第二时间段之前,第二信号的优先级高于第一信号的优先级,终端设备确定第一信号中的第一符号被丢弃;若第一时间段在第二时间段之后,第一信号的优先级高于第二信号的优先级,终端设备确定第二信号中的第二符号被丢弃。
示例性的,如图7a与图7b'所示,第一信号为PUCCH,第二信号为PUSCH,第二信号采用第一参考信号配置方式,具体为DMRS配置在PUSCH的第一个符号上,若第一时隙在第二时隙之前,如图7a所示,则PUSCH的优先级高于PUCCH的优先级,终端设备确定PUCCH在第一时隙中的最后一个符号被丢弃;若第一时隙在第二时隙之后,如图7b'所示,则PUCCH的优先级高于PUSCH的优先级,终端设备确定PUSCH在第二时隙中的最后一个符号被丢弃。
在第二信号采用第二参考信号配置方式的情况下,第一信号的优先级高于第二信号的优先级。
示例性的,如图7c与图7d所示,第一信号为PUCCH,第二信号为PUSCH,第二信号采用第二参考信号配置方式,具体为DMRS配置在PUSCH的第三个符号或第四个符号上,以DMRS配置在PUSCH的第三个符号为例,PUCCH的优先级高于PUSCH的优先级,终端设备确定PUSCH中的第二符号被丢弃。比如,在图7c中,确定被丢弃的符号为 PUSCH在第二时隙中的第一个符号,在图7d中,确定被丢弃的符号为PUSCH在第二时隙中的最后一个符号。
可以看出,在该实现方式中,确定为被丢弃的符号位置都不包括配置了DMRS的位置。
进一步的,在一种实现方式中,如果第一信号中不包含应答反馈信息,可以采用上述任意一种实现方式确定第一信号与第二信号的优先级;如果第一信号中包含应答反馈信息,可以采用现有技术中的方式确定第一信号与第二信号的优先级,比如,PUCCH的优先级高于PUSCH的优先级。
具体的,上行信号为PUCCH时,PUCCH中可以包含应答反馈信息和CSI等。示例性的,如果确定PUCCH中不包含应答反馈信息,比如,PUCCH中只包括CSI,则可以采用上述任意一种实现方式确定第一信号与第二信号的优先级,从而确定被丢弃的符号;如果确定PUCCH中包含应答反馈信息,则确定PUCCH的优先级高于PUSCH的优先级。
S104、终端设备向网络设备发送第一信号和第二信号。
若终端设备确定第一信号中的第一符号被丢弃,向网络设备发送第一信号中除第一符号之外的其他符号和第二信号;若终端设备确定第二信号中的第二符号被丢弃,向网络设备发送第一信号和第二信号中除第二符号之外的其他符号。其中,确定某一个符号被丢弃,表示终端设备向网络设备发送上行信号时,不发送该符号位置处对应的上行信号。一个或多个符号内的上行信号不发送,该符号占用的时间可以用于完成射频回路的工作频率的调整。
示例性的,终端设备确定第一信号中的第一符号被丢弃,如图7a和图7c'所示,终端设备确定PUCCH在第一时隙中的最后一个符号被丢弃,在第一时隙中的第一个至第十三个符号的时间内向网络设备发送PUCCH,以及在第二时隙中的全部符号的时间内向网络设备发送PUSCH;如图7b所示,终端设备确定PUCCH在第一时隙中的第一个符号被丢弃,在第二时隙中的全部符号的时间内向网络设备发送PUSCH,以及在第一时隙中的第二个至第十四个符号的时间内向网络设备发送PUCCH。
示例性的,终端设备确定第二信号中的第二符号被丢弃,如图7b'和图7d所示,终端设备确定PUSCH在第二时隙中的最后一个符号被丢弃,在第二时隙中的第一个至第十三个符号的时间内向网络设备发送PUSCH,以及在第一时隙中的全部符号的时间内向网络设备发送PUCCH;如图7c所示,终端设备确定PUSCH在第二时隙中的第一个符号被丢弃,在第一时隙中的全部符号的时间内向网络设备发送PUCCH,以及在第二时隙中的第二个至第十四个符号的时间内向网络设备发送PUSCH。
进一步的,在第二信号中的第二符号被丢弃的情况下,可以只丢弃第二信号中的一个符号,也可以丢弃第二信号的所有符号。
在一种实现方式中,若第二信号中包含额外的解调参考信号,第二符号为第二信号的第一个符号,终端设备向网络设备发送第一信号和第二信号中除第一个符号之外的其他符号。示例性的,如图7c所示,若图7c中的PUSCH中包含额外的DMRS,比如,在PUSCH的第七个符号位置上配置了额外的DMRS,则被丢弃的第二符号为PUSCH的第一个符号,终端设备在第一时隙中的全部符号的时间内向网络设备发送PUCCH,以及在第二时隙中的第二个至第十四个符号的时间内向网络设备发送PUSCH。
若第二信号中不包含额外的解调参考信号,第二符号为第二信号的所有符号,终端设备向网络设备发送第一信号。示例性的,若PUSCH中不包含额外的DMRS,则被丢弃的第二符号为PUSCH的所有符号,终端设备在第一时隙中的全部符号的时间内向网络设备发送PUCCH。
在另一种实现方式中,若终端设备存在潜在的联合调度终端,第二符号为第二信号的所有符号,终端设备向网络设备发送第一信号。示例性的,终端设备只在第一时隙中的全部符号的时间内向网络设备发送PUCCH。
若终端设备不存在潜在的联合调度终端,第二符号为第二信号中除解调参考信号以外的第一个符号,或为第二信号的最后一个符号,终端设备向网络设备发送第一信号和第二信号中除第二符号之外的其他符号。
示例性的,如图8a所示,第一信号为PUCCH,第二信号为PUSCH,第一时隙在第二时隙之前,DMRS配置在PUSCH的第一个符号上。在一种可能的实现方式中,若终端设备不存在潜在的联合调度终端,终端设备确定丢弃第二信号中除解调参考信号以外的第一个符号,即丢弃PUSCH的第二个符号,并将DMRS映射在PUSCH的第二个符号位置上,如图8b所示,终端设备在第一时隙中的全部符号的时间内向网络设备发送PUCCH,以及在第二时隙中的第二个至第十四个符号的时间内向网络设备发送PUSCH。在另一种可能的实现方式中,若终端设备不存在潜在的联合调度终端,终端设备确定丢弃第二信号的最后一个符号,并将PUSCH中的第一个符号至第十三个符号分别延迟一个符号位置,如图8c所示,终端设备在第一时隙中的全部符号的时间内向网络设备发送PUCCH,以及在第二时隙中的第二个至第十四个符号的时间内向网络设备发送PUSCH。
S105、网络设备接收第一信号和第二信号。
若第二信号的优先级高于第一信号的优先级,网络设备在第一时间段内在第一上行载波上接收第一信号中除第一符号之外的其他符号,在第二时间段内在第二上行载波上接收第二信号。若第一信号的优先级高于第二信号的优先级,网络设备在第一时间段内在第一上行载波上接收第一信号,在第二时间段内在第二上行载波上接收第二信号中除第二符号之外的其他符号。
其中,网络设备确定第一信号与第二信号的优先级的方法与终端设备侧确定第一信号与第二信号的优先级的的方法相同,网络设备确定被丢弃符号的位置的方法与终端设备侧确定被丢弃符号的位置的方法相同,具体的确定方法可参考S103与S104中终端设备侧的确定方法,此处不再赘述。
示例性的,若第二信号的优先级高于第一信号的优先级,终端设备在第一时隙中的第一个至第十三个符号的时间内向网络设备发送PUCCH,以及在第二时隙中的全部符号的时间内向网络设备发送PUSCH;则网络设备在第一时隙中的第一个至第十三个符号的时间内接收PUCCH,以及在第二时隙中的全部符号的时间内接收PUSCH。若第一信号的优先级高于第二信号的优先级,终端设备在第一时隙中的全部符号的时间内向网络设备发送PUCCH,以及在第二时隙中的第二个至第十四个符号的时间内向网络设备发送PUSCH,则网络设备在第一时隙中的全部符号的时间内接收PUCCH,以及在第二时隙中的第二个至第十四个符号的时间内接收PUSCH。
本申请实施例提供的通信方法,在不同上行载波上进行切换的过程中,确定不同 上行信号的优先级,并确定丢弃符号的位置时,考虑了DMRS配置的位置。相比现有技术中,没有考虑DMRS配置的位置,而固定不同上行信号的优先级的方法,本申请实施例提供的通信方法,在确定不同上行信号的优先级以及丢弃符号的位置时,考虑了DMRS配置的位置,可以避免在不同上行载波上进行切换的过程中将DMRS丢弃,从而可以保证PUSCH能够正确传输。
需要说明的是,上述实施例中的丢弃符号指的是不发送该符号,被丢弃的符号指的是原本需要发送的符号,但是由于客观条件的限制,终端无法发送这些信号。此外,被丢弃的符号也可以理解为发送功率为0的符号。在实际的实现过程中,终端设备可以不存在确定待发送的第一信号和第二信号,并确定第一信号和第二信号的优先级,以及确定被丢弃符号位置的过程;而是在发送第一信号和第二信号时,直接不发送被丢弃符号对应位置处的上行信号。
在另一种实现方式中,如图9所示,本申请实施例提供的通信方法,可以包括S101、S102、S104'和S105,其中,S101、S102和S105与图5中S101、S102和S105相同,此处不再赘述;下面仅对S104'进行说明。
S104'、终端设备向网络设备发送第一信号和第二信号。
终端设备接收到第一指示信息和第二指示信息之后,
在一种实现方式中,终端设备确定在第二信号采用第一参考信号配置方式的情况下,发送第一信号中除第一符号之外的其他符合和第二信号;终端设备确定在第二信号采用第二参考信号配置方式的情况下,发送第一信号和第二信号中除第二符号之外的其他符号。
示例性的,如图7a与图7b所示,第一信号为PUCCH,第二信号为PUSCH,第二信号采用第一参考信号配置方式,具体为DMRS配置在PUSCH的第一个符号上,则发送PUCCH中除第一符号之外的其他符合和PUSCH。比如,在图7a中,终端设备可以在第一时隙中的第一个至第十三个符号的时间内向网络设备发送PUCCH,以及在第二时隙中的全部符号的时间内向网络设备发送PUSCH;在图7b中,终端设备在第二时隙中的全部符号的时间内向网络设备发送PUSCH,以及在第一时隙中的第二个至第十四个符号的时间内向网络设备发送PUCCH。
示例性的,如图7c与图7d所示,第一信号为PUCCH,第二信号为PUSCH,第二信号采用第二参考信号配置方式,具体为DMRS配置在PUSCH的第三个符号或第四个符号上,以DMRS配置在PUSCH的第三个符号为例,发送PUCCH和PUSCH中除第二符号之外的其他符号。比如,在图7c中,终端设备在第一时隙中的全部符号的时间内向网络设备发送PUCCH,以及在第二时隙中的第二个至第十四个符号的时间内向网络设备发送PUSCH;在图7d中,终端设备在第二时隙中的第一个至第十三个符号的时间内向网络设备发送PUSCH,以及在第一时隙中的全部符号的时间内向网络设备发送PUCCH。在另一种实现方式中,终端设备若确定第一时间段在第二时间段之前,发送第一信号中除第一符号之外的其他符合和第二信号;终端设备若确定第一时间段在第二时间段之后,发送第一信号和第二信号中除第二符号之外的其他符号。
示例性的,如图7a与图7c'所示,第一信号为PUCCH,第二信号为PUSCH,第一时隙在第二时隙之前,终端设备在第一时隙中的第一个至第十三个符号的时间内向网 络设备发送PUCCH,以及在第二时隙中的全部符号的时间内向网络设备发送PUSCH。
示例性的,如图7b'与图7d所示,第一时隙在第二时隙之后,终端设备在第二时隙中的第一个至第十三个符号的时间内向网络设备发送PUSCH,以及在第一时隙中的全部符号的时间内向网络设备发送PUCCH。
在另一种实现方式中,终端设备确定在第二信号采用第一参考信号配置方式的情况下,若第一时间段在第二时间段之前,发送第一信号中除第一符号之外的其他符合和第二信号;若确定第一时间段在第二时间段之后,发送第一信号和第二信号中除第二符号之外的其他符号。终端设备确定在第二信号采用第二参考信号配置方式的情况下,发送第一信号和第二信号中除第二符号之外的其他符号。
示例性的,如图7a与图7b'所示,第一信号为PUCCH,第二信号为PUSCH,第二信号采用第一参考信号配置方式,具体为DMRS配置在PUSCH的第一个符号上,若第一时隙在第二时隙之前,如图7a所示,则终端设备在第一时隙中的第一个至第十三个符号的时间内向网络设备发送PUCCH,以及在第二时隙中的全部符号的时间内向网络设备发送PUSCH;若第一时隙在第二时隙之后,如图7b'所示,则终端设备在第二时隙中的第一个至第十三个符号的时间内向网络设备发送PUSCH,以及在第一时隙中的全部符号的时间内向网络设备发送PUCCH。
示例性的,如图7c与图7d所示,第一信号为PUCCH,第二信号为PUSCH,第二信号采用第二参考信号配置方式,具体为DMRS配置在PUSCH的第三个符号或第四个符号上,以DMRS配置在PUSCH的第三个符号为例。比如,在图7c中,终端设备在第一时隙中的全部符号的时间内向网络设备发送PUCCH,以及在第二时隙中的第二个至第十四个符号的时间内向网络设备发送PUSCH;在图7d中,终端设备在第二时隙中的第一个至第十三个符号的时间内向网络设备发送PUSCH,以及在第一时隙中的全部符号的时间内向网络设备发送PUCCH。
进一步的,在一种实现方式中,如果第一信号中不包含应答反馈信息,可以采用上述任意一种实现方式发送上行信号;如果第一信号中包含应答反馈信息,可以采用现有技术中的方式发送上行信号。
进一步的,在发送第一信号和第二信号中除第二符号之外的其他符号的情况下,第二符号可以是第二信号中的一个符号,也可以是第二信号的所有符号。
在一种实现方式中,若第二信号中包含额外的解调参考信号,第二符号为第二信号的第一个符号,终端设备向网络设备发送第一信号和第二信号中除第一个符号之外的其他符号。示例性的,如图7c所示,若图7c中的PUSCH中包含额外的DMRS,比如,在PUSCH的第七个符号位置上配置了额外的DMRS,则终端设备在第一时隙中的全部符号的时间内向网络设备发送PUCCH,以及在第二时隙中的第二个至第十四个符号的时间内向网络设备发送PUSCH。
若第二信号中不包含额外的解调参考信号,第二符号为第二信号的所有符号,终端设备向网络设备发送第一信号。示例性的,若PUSCH中不包含额外的DMRS,则终端设备在第一时隙中的全部符号的时间内向网络设备发送PUCCH。
在另一种实现方式中,若终端设备存在潜在的联合调度终端,第二符号为第二信号的所有符号,终端设备向网络设备发送第一信号。示例性的,终端设备只在第一时 隙中的全部符号的时间内向网络设备发送PUCCH。
若终端设备不存在潜在的联合调度终端,第二符号为第二信号中除解调参考信号以外的第一个符号,或为第二信号的最后一个符号,终端设备向网络设备发送第一信号和第二信号中除第二符号之外的其他符号。
示例性的,如图8a所示,第一信号为PUCCH,第二信号为PUSCH,第一时隙在第二时隙之前,DMRS配置在PUSCH的第一个符号上。在一种可能的实现方式中,若终端设备不存在潜在的联合调度终端,终端设备将DMRS映射在PUSCH的第二个符号位置上,如图8b所示,终端设备在第一时隙中的全部符号的时间内向网络设备发送PUCCH,以及在第二时隙中的第二个至第十四个符号的时间内向网络设备发送PUSCH。在另一种可能的实现方式中,若终端设备不存在潜在的联合调度终端,终端设备将PUSCH中的第一个符号至第十三个符号分别延迟一个符号位置,如图8c所示,终端设备在第一时隙中的全部符号的时间内向网络设备发送PUCCH,以及在第二时隙中的第二个至第十四个符号的时间内向网络设备发送PUSCH。
本申请实施例提供的通信方法,在不同上行载波上进行切换的过程中,根据上行信号的优先级发送上行信号时考虑了DMRS配置的位置。相比现有技术中,没有考虑DMRS配置的位置,而固定不同上行信号的优先级的方法,本申请实施例提供的通信方法,在发送上行信号时,考虑了DMRS配置的位置,可以避免在不同上行载波上进行切换的过程中将DMRS丢弃,从而可以保证PUSCH能够正确传输。
