Description

无线通信方法和设备 技术领域
本申请实施例涉及通信领域,并且更具体地,涉及无线通信方法和设备。
背景技术
在新空口(New Radio,NR)系统中,终端设备侧数据传输的吞吐量会受到往返传输时间(Round Trip Time,RTT)和终端设备被配置的混合自动重传请求(Hybrid Automatic Repeat Request,HARQ)进程的数量的影响。例如,假设终端设备被配置的最大HARQ进程数为16,对于15kHz子载波间隔,在RTT小于16ms的情况下,不影响该终端设备的最大吞吐量,或者说,如果RTT小于16ms,在有业务要传输时,该终端设备总是可以有并行的HARQ进程来进行数据传输;在RTT远大于16ms的情况下,可能存在终端设备的所有HARQ进程都被用于数据传输,且并未获得网络设备的反馈,从而导致终端设备有业务待传输却没有HARQ进程可以被使用的情况,进而会影响终端设备侧数据传输的吞吐量。
但是,在非地面通信网络(Non-Terrestrial Network,NTN)系统中,由于终端设备和卫星(或者网络设备)之间的通信距离很远,即NTN系统中信号传输的RTT远大于地面通信系统中信号传输的RTT,因此,现有新空口(New Radio,NR)系统中的混合自动重传请求(Hybrid Automatic Repeat Request,HARQ)机制不再适用于NTN系统。
因此,本领域亟需一种适用于NTN系统的HARQ机制,以保证数据传输的吞吐量。

具体实施方式
下面将结合附图,对本申请实施例中的技术方案进行描述。
图1是本申请实施例的一个应用场景的示意图。
如图1所示,通信系统100可以包括终端设备110和网络设备120。网络设备120可以通过空口与终端设备110通信。终端设备110和网络设备120之间支持多业务传输。
应理解,本申请实施例仅以通信系统100进行示例性说明,但本申请实施例不限定于此。也就是说,本申请实施例的技术方案可以应用于各种通信系统,例如:长期演进(Long Term Evolution,LTE)系统、LTE时分双工(Time Division Duplex,TDD)、通用移动通信系统(Universal Mobile Telecommunication System,UMTS)、5G通信系统(也称为新无线(New Radio,NR)通信系统),或未来的通信系统等。
应理解,本申请实施例可应用于非地面通信网络(Non-Terrestrial Networks,NTN)系统,也可应用于地面通信网络(Terrestrial Networks,TN)系统。
作为示例,NTN系统至少包括新无线非地面通信网络(New Radio NTN,NR-NTN)系统和物联网非地面通信网络(Internet of Things NTN,IoT-NTN)系统。其中,IoT-NTN系统可以包括窄带物联网非地面通信网络(Narrow Band Internet of Things over NTN,NB-IoT-NTN)系统和增强的机器类型通信非地面通信网络(enhanced Machine Type Communication over NTN,eMTC-NTN)系统。
在图1所示的通信系统100中,网络设备120可以是与终端设备110通信的接入网设备。接入网设备可以为特定的地理区域提供通信覆盖,并且可以与位于该覆盖区域内的终端设备110(例如UE)进行通信。
网络设备120可以是长期演进(Long Term Evolution,LTE)系统中的演进型基站(Evolutional Node B,eNB或eNodeB),或者是下一代无线接入网(Next Generation Radio Access Network,NG RAN)设备,或者是NR系统中的基站(gNB),或者是云无线接入网络(Cloud Radio Access Network,CRAN)中的无线控制器,或者该网络设备120可以为中继站、接入点、车载设备、可穿戴设备、集线器、交换机、网桥、路由器,或者未来演进的公共陆地移动网络(Public Land Mobile Network,PLMN)中的网络设备等。
终端设备110可以是任意终端设备,其包括但不限于与网络设备120或其它终端设备采用有线或者无线连接的终端设备。
例如,所述终端设备110可以指接入终端、用户设备(User Equipment,UE)、用户单元、用户站、移动站、移动台、远方站、远程终端、移动设备、用户终端、终端、无线通信设备、用户代理或用户装置。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网络中的终端设备或者未来演进网络中的终端设备等。
终端设备110可以用于设备到设备(Device to Device,D2D)的通信。
无线通信系统100还可以包括与基站进行通信的核心网设备130,该核心网设备130可以是5G核心网(5G Core,5GC)设备,例如,接入与移动性管理功能(Access and Mobility Management Function,AMF),又例如,认证服务器功能(Authentication Server Function,AUSF),又例如,用户面功能(User Plane Function,UPF),又例如,会话管理功能(Session Management Function,SMF)。可选地,核心网络设备130也可以是LTE网络的分组核心演进(Evolved Packet Core,EPC)设备,例如,会话管理功能+核心网络的数据网关(Session Management Function+Core Packet Gateway,SMF+PGW-C)设备。应理解,SMF+PGW-C可以同时实现SMF和PGW-C所能实现的功能。在网络演进过程中,上述核心网设备也有可能叫其它名字,或者通过对核心网的功能进行划分形成新的网络实体,对此本申请实施例不做限制。
通信系统100中的各个功能单元之间还可以通过下一代网络(next generation,NG)接口建立连接实现通信。
例如,终端设备通过NR接口与接入网设备建立空口连接,用于传输用户面数据和控制面信令;终端设备可以通过NG接口1(简称N1)与AMF建立控制面信令连接;接入网设备例如下一代无线接入 基站(gNB),可以通过NG接口3(简称N3)与UPF建立用户面数据连接;接入网设备可以通过NG接口2(简称N2)与AMF建立控制面信令连接;UPF可以通过NG接口4(简称N4)与SMF建立控制面信令连接;UPF可以通过NG接口6(简称N6)与数据网络交互用户面数据;AMF可以通过NG接口11(简称N11)与SMF建立控制面信令连接;SMF可以通过NG接口7(简称N7)与PCF建立控制面信令连接。
图1示例性地示出了一个基站、一个核心网设备和两个终端设备,可选地,该无线通信系统100可以包括多个基站设备并且每个基站的覆盖范围内可以包括其它数量的终端设备,本申请实施例对此不做限定。
在新无线(New Radio,NR)系统中,考虑采用非地面通信网络(Non-Terrestrial Networks,NTN)向用户提供通信服务。NTN一般采用卫星通信的方式向地面用户提供通信服务。相比地面蜂窝网通信,卫星通信具有很多独特的优点。首先,卫星通信不受用户地域的限制,例如一般的陆地通信不能覆盖海洋、高山、沙漠等无法搭设通信设备或由于人口稀少而不做通信覆盖的区域,而对于卫星通信来说,由于一颗卫星即可以覆盖较大的地面,加之卫星可以围绕地球做轨道运动,因此理论上地球上每一个角落都可以被卫星通信覆盖。其次,卫星通信有较大的社会价值。卫星通信在边远山区、贫穷落后的国家或地区都可以以较低的成本覆盖到,从而使这些地区的人们享受到先进的语音通信和移动互联网技术,有利于缩小与发达地区的数字鸿沟,促进这些地区的发展。再次,卫星通信距离远,且通信距离增大通讯的成本没有明显增加;最后,卫星通信的稳定性高,不受自然灾害的限制。
图2为本申请实施例提供的另一种通信系统的架构示意图。
如图2所示,包括终端设备1101和卫星1102,终端设备1101和卫星1102之间可以进行无线通信。终端设备1101和卫星1102之间所形成的网络还可以称为NTN。在图2所示的通信系统的架构中,卫星1102可以具有基站的功能,终端设备1101和卫星1102之间可以直接通信。在系统架构下,可以将卫星1102称为网络设备。在本申请的一些实施例中,通信系统中可以包括多个网络设备1102,并且每个网络设备1102的覆盖范围内可以包括其它数量的终端设备,本申请实施例对此不做限定。
图3为本申请实施例提供的另一种通信系统的架构示意图。
如图3所示,包括终端设备1201、卫星1202和基站1203,终端设备1201和卫星1202之间可以进行无线通信,卫星1202与基站1203之间可以通信。终端设备1201、卫星1202和基站1203之间所形成的网络还可以称为NTN。在图3所示的通信系统的架构中,卫星1202可以不具有基站的功能,终端设备1201和基站1203之间的通信需要通过卫星1202的中转。在该种系统架构下,可以将基站1203称为网络设备。在本申请的一些实施例中,通信系统中可以包括多个网络设备1203,并且每个网络设备1203的覆盖范围内可以包括其它数量的终端设备,本申请实施例对此不做限定。所述网络设备1203可以是图1中的网络设备120。
应理解,上述卫星1102或卫星1202包括但不限于:
低地球轨道(Low-Earth Orbit,LEO)卫星、中地球轨道(Medium-Earth Orbit,MEO)卫星、地球同步轨道(Geostationary Earth Orbit,GEO)卫星、高椭圆轨道(High Elliptical Orbit,HEO)卫星等等。卫星可采用多波束覆盖地面,例如,一颗卫星可以形成几十甚至数百个波束来覆盖地面。换言之,一个卫星波束可以覆盖直径几十至上百公里的地面区域,以保证卫星的覆盖以及提升整个卫星通信系统的系统容量。
作为示例,LEO的高度范围可以为500km~1500km,相应轨道周期约可以为1.5小时~2小时,用户间单跳通信的信号传播延迟一般可小于20ms,最大卫星可视时间可以为20分钟,LEO的信号传播距离短且链路损耗少,对用户终端的发射功率要求不高。GEO的轨道高度可以35786km,围绕地球旋转周期可以24小时,用户间单跳通信的信号传播延迟一般可为250ms。
通常情况下,为了保证卫星的覆盖以及提升整个卫星通信系统的系统容量,卫星采用多波束覆盖地面,一颗卫星可以形成几十甚至数百个波束来覆盖地面;一个卫星波束可以覆盖直径几十至上百公里的地面区域。
需要说明的是,图1至图3只是以示例的形式示意本申请所适用的系统,当然,本申请实施例所示的方法还可以适用于其它系统。此外,本文中术语“系统”和“网络”在本文中常被可互换使用。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。另外,本文中字符“/”,一般表示前后关联对象是一种“或”的关系。还应理解,在本申请的实施例中提到的“指示”可以是直接指示,也可以是间接指示,还可以是表示具有关联关系。举例说明,A指示B,可以表示A直接指示B,例如B可以通过A获取;也可以表示A间接指示B,例如A指示C,B可以通过C获取;还可以表示A和B之间具有关联关系。
卫星从其提供的功能上可以分为透传转发(transparent payload)和再生转发(regenerative payload)两种。对于透传转发卫星,只提供无线频率滤波,频率转换和放大的功能,只提供信号的透明转发,不会改变其转发的波形信号。对于再生转发卫星,除了提供无线频率滤波,频率转换和放大的功能,还可以提供解调/解码,路由/转换,编码/调制的功能,其具有基站的部分或者全部功能。
在NTN中,可以包括一个或多个网关(Gateway),用于卫星和终端之间的通信。
图4和图5分别示出了基于透传转发卫星和再生转发卫星的NTN场景的示意图。
如图4所示,对于基于透传转发卫星的NTN场景,网关和卫星之间通过馈线链路(Feeder link)进行通信,卫星和终端之间可以通过服务链路(service link)进行通信。如图5所示,对于基于再生转发卫星的NTN场景,卫星和卫星之间通过星间(InterStar link)进行通信,网关和卫星之间通过馈线链路(Feeder link)进行通信,卫星和终端之间可以通过服务链路(service link)进行通信。
随着人们对速率、延迟、高速移动性、能效的追求以及未来生活中业务的多样性、复杂性,3GPP国际标准组织开始研发5G。5G的主要应用场景包括:增强移动超宽带(Enhance Mobile Broadband,eMBB)、低时延高可靠通信(Ultra-Reliable and Low Latency Communication,URLLC)、大规模机器类通信(massive machine type of communication,mMTC)。其中,eMBB以用户获得多媒体内容、服务和数据为目标,其需求增长十分迅速。由于eMBB可能部署在不同的场景中。例如,室内,市区,农村等,其能力和需求的差别也比较大,所以不能一概而论,可以结合具体的部署场景详细分析。URLLC的典型应用包括:工业自动化,电力自动化,远程医疗操作(手术),交通安全保障等。mMTC的典型特点包括:高连接密度,小数据量,时延不敏感业务,模块的低成本和长使用寿命等。
在新空口(New Radio,NR)系统中,终端设备侧数据传输的吞吐量会受到往返传输时间(Round Trip Time,RTT)和终端设备被配置的混合自动重传请求(Hybrid Automatic Repeat Request,HARQ)进程的数量的影响。例如,假设终端设备被配置的最大HARQ进程数为16,对于15kHz子载波间隔,在RTT小于16ms的情况下,不影响该终端设备的最大吞吐量,或者说,如果RTT小于16ms,在有业务要传输时,该终端设备总是可以有并行的HARQ进程来进行数据传输;在RTT远大于16ms的情况下,可能存在终端设备的所有HARQ进程都被用于数据传输,且并未获得网络设备的反馈,从而导致终端设备有业务待传输却没有HARQ进程可以被使用的情况,进而会影响终端设备侧数据传输的吞吐量。
图6是本申请实施例提供的HARQ进程和RTT之间的关系的示意性图。
如图6所示,假设终端设备被配置的最大下行HARQ进程数为16,且RTT小于16ms,则该终端设备在RTT内总是可以有并行的下行HARQ进程来进行数据传输;例如,第1个时隙(即PUSCH 0所在的时隙)至第16个时隙(即PUSCH 0/PUSCH 1所在的时隙的前一个时隙)可分别对应下行HARQ 0至下行HARQ 15,第17个时隙(PUSCH 0/PUSCH 1所在的时隙)可以重新采用HARQ 0进程来进行数据传输,由此可见,HARQ进程和RTT之间的关系不会影响该终端设备的最大吞吐量。
但是,在非地面通信网络(Non-Terrestrial Network,NTN)系统中,由于终端设备和卫星(或者网络设备)之间的通信距离很远,信号传输的RTT很大。例如在GEO系统中,信号传输的RTT可以为百毫秒量级,例如信号传输的RTT最大可以为约600ms。再如在LEO系统中,信号传输的RTT可以为几十毫秒量级。由于NTN系统中信号传输的RTT远大于地面通信系统中信号传输的RTT,因此,现有新空口(New Radio,NR)系统中的混合自动重传请求(Hybrid Automatic Repeat Request,HARQ)机制不再适用于NTN系统。
基于此,本申请实施例提供了一种无线通信方法,针对NTN系统,其不仅能够保证终端设备侧数据传输的吞吐量,还能够使得终端设备正确生成对应的HARQ-ACK信息,避免网络设备和处于连接态或初始接入过程中的终端设备对HARQ-ACK信息生成的理解不一致,进而提升了数据传输的吞吐量。
图7示出了根据本申请实施例的无线通信方法200的示意性流程图,所述方法200可以由终端设备和网络设备交互执行。例如,图7中所示的终端设备可以是如图1所示的终端设备,图7中所示的网络设备可以是如图1所示的接入网设备。再如,图7中所示的终端设备可以是如图2所示的终端设备1101或图3所示的终端设备1201,图7中所示的网络设备可以是如图2所示的卫星1102或图3所示的卫星1202。
如图7所示,所述方法200可包括以下部分或全部内容:
S210,获取第一调度信息,所述第一调度信息调度使用第一混合自动重传请求HARQ进程传输第一物理信道;
S220,基于所述第一HARQ进程对应的目标状态进行所述第一物理信道的传输;
其中,所述第一HARQ进程配置为对应去使能态,所述目标状态为使能态或去使能态。
一方面,将所述第一HARQ进程配置为对应去使能态,相当于,在所述第一物理信道传输的过程 中,可以避免RTT对所述第一物理信道的传输带来影响,进而能够保证数据传输的吞吐量;另一方面,将所述第一HARQ进程对应的目标状态设计为使能态或去使能态,相当于,即使将所述第一HARQ进程配置为对应去使能态,也可基于使能态的所述第一HARQ进程进行所述第一物理信道的传输,能够使得终端设备根据实际需求正确生成对应的HARQ-ACK信息,避免了网络设备和处于连接态或初始接入过程中的终端设备对HARQ-ACK信息生成的理解不一致,进而提升了数据传输的可靠性。因此,针对NTN系统,本申请提供的无线通信方法不仅能够保证终端设备侧数据传输的吞吐量,还能够提升数据传输的吞吐量。
需要说明的是,本申请可以通过对所述第一HARQ进程的去使能,保证数据传输的吞吐量。
例如,假设所述第一HARQ进程为终端设备被配置为对应去使能的下行HARQ进程,对于所述第一HARQ进程,网络设备不需要接收到终端设备针对所述第一HARQ进程中传输的传输块(TB)反馈的HARQ-ACK信息,即可重用所述第一HARQ进程进行下行传输;或终端设备重用所述第一HARQ进程接收下行传输时,不需要受到该终端设备是否反馈上一次所述第一HARQ进程中传输的TB对应的HARQ-ACK信息的限制。因此,在RTT时间内,网络设备可以使用所述第一HARQ进程为终端设备进行多个下行数据包的调度,从而可以减少RTT带来的影响,保证了终端设备侧数据传输的吞吐量。
再如,假设所述第一HARQ进程为终端设备被配置为对应去使能的上行HARQ进程,对于所述第一HARQ进程,网络设备不需要接收到终端设备通过所述第一HARQ进程传输的上行信道,即可调度该终端设备重用所述第一HARQ进程进行上行传输;或终端设备在RTT时间内可以收到多个调度使用所述第一HARQ进程进行上行传输的上行授权信息。因此,在RTT时间内,网络设备可以使用所述第一HARQ进程为终端设备进行多个上行数据包的调度,从而可以减少RTT带来的影响,保证了终端设备侧数据传输的吞吐量。
此外,虽然可以将所述第一HARQ进程以配置为对应去使能的方式保证数据传输的吞吐量,然而,在一些情况下,终端设备仍然需要反馈对应的HARQ-ACK信息,例如在随机接入过程中收到使用所述第一HARQ进程的PDSCH时,即使所述第一HARQ进程配置为对应去使能,终端设备也需要反馈对应的HARQ-ACK信息,且需要保证网络设备和终端设备对HARQ-ACK信息生成的理解一致,基于此,本申请将所述第一HARQ进程对应的目标状态设计为使能态或去使能态,并基于所述第一HARQ进程对应的目标状态进行所述第一物理信道的传输,能够使得终端设备根据实际需求正确生成对应的HARQ-ACK信息,避免了网络设备和处于连接态或初始接入过程中的终端设备对HARQ-ACK信息生成的理解不一致,进而提升了数据传输的可靠性。
在一些情况中,在NR系统及其演进系统例如NTN系统或高频系统中,将所述第一HARQ进程配置为对应去使能态可以是一种终端设备能力。即有些终端设备支持将所述第一HARQ进程配置为对应去使能态,有些终端设备不支持将所述第一HARQ进程配置为对应去使能态,或者说,不是所有的终端设备支持将所述第一HARQ进程配置为对应去使能态。
此外,本申请中,所述第一HARQ进程可以为网络设备为终端设备配置的任意下行HARQ进程。换言之,终端设备的部分或全部下行HARQ进程可以被配置第一高层参数,其中所述第一高层参数用于指示HARQ进程是否对应去使能态,或所述第一高层参数用于指示HARQ进程是否对应使能态,所述部分或全部下行HARQ进程包括所述第一HARQ进程。终端设备的下行HARQ进程可以配置为对应去使能态,或下行HARQ进程对应的HARQ反馈功能状态可以配置为去使能态。例如,网络设备可以通过指示信息例如第一高层参数将终端设备的部分或全部下行HARQ进程配置为使能态或者去使能态,或者,网络设备可以通过指示信息将终端设备的部分或全部下行HARQ进程对应的HARQ反馈功能状态配置为使能态或者去使能态。其中去使能态(disabled)也称为非使能态。
类似的,所述第一HARQ进程可以为网络设备为终端设备配置的任意上行HARQ进程。换言之,终端设备的部分或全部上行HARQ进程可以被配置第二高层参数,其中所述第二高层参数用于指示HARQ进程是否对应去使能态,或所述第二高层参数用于指示HARQ进程是否对应使能态,所述部分或全部上行HARQ进程包括所述第一HARQ进程。终端设备的上行HARQ进程可以配置为对应去使能态,或上行HARQ进程对应的HARQ反馈功能状态可以配置为去使能态。例如,网络设备可以通过指示信息例如第一高层参数将终端设备的部分或全部上行HARQ进程配置为使能态或者去使能态,或者,网络设备可以通过指示信息将终端设备的部分或全部上行HARQ进程对应的HARQ反馈功能状态配置为使能态或者去使能态。其中去使能态(disabled)也称为非使能态。
本申请实施例中的高层参数例如第一高层参数或第二高层参数包括系统消息、无线资源控制(Radio Resource Control,RRC)信令和媒体接入控制单元(Media Access Control Control Element,MAC CE)中的至少一种。
可选的,所述第一物理信道包括物理下行共享信道(Physical Downlink Shared channel,PDSCH) 和/或物理上行共享信道(Physical Uplink Shared channel,PUSCH)。
作为示例,当所述第一物理信道为PDSCH时,所述第一物理信道可以为物理下行控制信道(Physical Downlink Control Channel,PDCCH)调度的PDSCH,或者,所述第一物理信道可以为SPS PDSCH。
作为示例,当所述第一物理信道为PUSCH时,所述第一物理信道可以为PDCCH调度的PUSCH,或者,所述第一物理信道可以为预配置CG PUSCH,或者,所述第一物理信道可以为随机接入响应(Random Access Response,RAR)中的上行授权信息调度的PUSCH,或者,所述第一物理信道可以为消息A(MsgA)中的MsgA PUSCH。其中,该RAR可以包括但不限于四步随机接入过程中的RAR(或称MAC RAR),或两步随机接入过程中的回退RAR(fallbackRAR,或称MAC fallbackRAR)。
在一些实施例中,当所述第一HARQ进程配置为对应去使能态,且使用所述第一HARQ进程传输SPS PDSCH和/或CG PUSCH时,所述目标状态为去使能态;或者,当所述第一HARQ进程未被配置为对应去使能态时,且使用所述第一HARQ进程传输SPS PDSCH和/或CG PUSCH时,所述目标状态为使能态。
在一些实施例中,当所述第一HARQ进程配置为对应去使能态,且使用所述第一HARQ进程传输SPS PDSCH和/或CG PUSCH时,所述目标状态为使能态。

在本申请实施例中,终端设备可以根据第一信息确定第一HARQ进程对应的目标状态,进一步可以基于所述第一HARQ进程对应的目标状态进行所述第一物理信道的传输。对应地,网络设备也可以根据第一信息确定用于确定第一HARQ进程对应的目标状态,进一步可以基于所述第一HARQ进程对应的目标状态进行所述第一物理信道的传输,从而能够保证网络设备和终端设备对于第一HARQ进程 对应的目标状态的理解一致。
综上所述,本申请提供的无线通信方法中,在终端设备被配置HARQ进程去使能的情况下,通过预设规则的方式,可以使终端设备确定在不同场景下被配置去使能的HARQ进程对应的不同的状态,例如使能态或去使能态,从而可以使终端设备正确生成对应的HARQ-ACK信息,避免网络设备和处于连接态或初始接入过程中的终端设备对HARQ-ACK信息生成的理解不一致。
本申请实施例还提供了另一种无线通信方法,通过为终端设备配置更多的HARQ进程数量,来保证终端设备侧数据传输的吞吐量。
在终端设备能力允许的范围内,网络设备为终端设备配置的HARQ进程数量可以超过现有网络支持的最大HARQ进程数。例如,现有网络支持的最大HARQ进程数为第一数值例如16,网络设备为终端设备配置的HARQ进程数为大于16。通过增加HARQ进程数量,可以使得网络设备和终端设备之间可以并行传输的数据包增加,从而可以减少RTT带来的影响,进而保证了终端设备侧的数据传输的吞吐量。
示例性地,对应DCI格式1_0的下行授权或对应DCI格式0_0的上行授权中的HARQ进程号指示域最多包括4个比特,即最大可以指示的HARQ进程数为16。
示例性地,终端设备在初始接入阶段,调度下行数据接收或调度上行数据发送的DCI格式是回退DCI格式例如DCI格式0_0或DCI格式1_0,回退DCI格式对应的DCI中能指示的最大HARQ进程数量为16。对于支持的HARQ进程数量大于16的终端设备,网络设备可以在该终端设备接入网络后,为该终端设备配置大于16的HARQ进程数量。进一步地,网络设备和终端设备可以使用对DCI格式0_0或DCI格式1_0中的信息域进行重解读的方式,来支持大于16的HARQ进程的调度。如果网络设备为终端设备配置的HARQ进程数量超过16,一种可能的方式是通过对DCI中的信息域进行重解读来指示HARQ进程号。例如,HARQ进程号中的高位比特(MSB)可以根据RV域中的1比特来指示。然而,如何确保网络设备和终端设备对调度数据传输的HARQ进程号理解一致,例如什么时候需要对DCI格式0_0或DCI格式1_0中的信息域进行重解读,什么时候不需要对DCI格式0_0或DCI格式1_0中的信息域进行重解读,是进一步待解决的技术问题。
图8示出了根据本申请实施例的无线通信方法300的示意性流程图,所述方法300可以由终端设备和网络设备交互执行。例如,图8中所示的终端设备可以是如图1所示的终端设备,图8中所示的网络设备可以是如图1所示的接入网设备。再如,图8中所示的终端设备可以是如图2所示的终端设备1101或图3所示的终端设备1201,图8中所示的网络设备可以是如图2所示的卫星1102或图3所示的卫星1202。
如图8所示,所述方法300可包括以下部分或全部内容:
S310,获取第一调度信息,所述第一调度信息调度使用第一混合自动重传请求HARQ进程传输第一物理信道;
S320,基于所述第一HARQ进程对应的目标HARQ进程号范围确定所述第一HARQ进程对应的进程号;
其中,所述目标HARQ进程号范围为第一HARQ进程号范围或第二HARQ进程号范围,所述第一HARQ进程号范围对应第一数值,所述第二HARQ进程号范围对应第二数值,所述第二数值大于所述第一数值;
其中,终端设备被配置的HARQ进程数大于所述第一数值。
换言之,如果终端设备被配置HARQ进程数量大于第一数值,当终端设备收到使用第一调度信息调度的使用第一HARQ进程进行的第一物理信道传输时,终端设备需要确定第一HARQ进程对应所述第一HARQ进程号范围(所述第一HARQ进程号范围对应第一数值)或所述第二HARQ进程号范围(所述第二HARQ进程号范围对应第二数值,所述第二数值大于所述第一数值),从而基于所述第一HARQ进程对应的目标HARQ进程号范围确定所述第一HARQ进程对应的进程号。
需要说明的是,在NR系统及其演进系统例如NTN系统或高频系统中,为终端设备配置更多的HARQ进程数量,即HARQ进程数量的增加是一种终端设备能力。即有些终端设备支持的HARQ进程数量可以大于16,有些终端设备支持的HARQ进程数量不能大于16,或者说,可以不是所有的终端设备支持的HARQ进程数量都大于16。
