背景技术
目前第五代移动通信技术(5G,the 5th Generation mobile communication technology,也可以称为新空口(New Radio,简称NR))的第一阶段的标准制定工作已经完成。从标准制定和技术发展的趋势来看,5G系统致力于研究更高速率、巨量链接、超低时延、更高的可靠性、百倍的能量效率提升等技术指标以支撑新的需求变化。基于NR的非授权频谱接入(NR-based Access to Unlicensed Spectrum,简称NR-U)技术在物联网、工厂自动化等各方面都有很大的应用前景,但目前NR-U还面临诸多问题需要解决。
对于非授权频谱的使用需要遵循一定的管制政策,例如设备在使用非授权载波发送数据之前必须要执行先听后说(Listen Before Talk,简称LBT,也可以称为空闲信道评估(Clear Channel Assessment,简称CCA)),只有LBT成功的设备才能在非授权载波上发送数据。在NR-U中,不同优先级业务在发送数据之前,均需要执行LBT。为了满足高优先级业务的指标需求,在不同的条件下,高优先级业务可能需要抢占低优先级业务的资源用于发送高优先级业务数据,在NR-U中关于不同优先级业务如何复用,以及如何在复用中执行LBT,目前还没有可行的方案。

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明白,下文中将结合附图对本申请的实施例进行详细说明。需要说明的是,在不冲突的情况下,本申请中的实施例及实施例中的特征可以相互任意组合。
本申请提供的数据传输方法可以应用于由第一通信终端及第二通信终端组成的通信系统中。图1为一实施例提供的一种数据传输方法的应用场景的示意图。如图1所示,第一通信终端11、第二通信终端12、通信节点13及第三通信终端14组成一个通信系统。该通信系统可以是全球移动通信系统(Global System for Mobile Communications,GSM)、通用分组无线业务(General Packet Radio Service,GPRS)系统、码分多址(Code Division Multiple Access,CDMA)系统、CDMA2000系统、宽带码分多址(Wideband Code Division Multiple Access,WCDMA)系统、长期演进(Long Term Evolution,LTE)系统、LTE-A系统、 5G系统或全球微波接入互操作性(World Interoperability for Microwave Access,WiMAX)系统等。在该通信系统中,第一通信终端11和第二通信终端12使用非授权载波传输数据,可选地,第一通信终端传输的第一数据的优先级高于第二通信终端传输的第二数据的优先级。本实施例中的第一数据对应的业务与第二数据对应的业务的不同体现在以下至少之一:第一数据对应的业务所要求的时延比第二数据对应的业务的时延更低、第一数据对应的业务所要求的可靠性比第二数据对应的业务的可靠性更高、第一数据对应的业务所指定的优先级高于第二数据对应的业务所指定的优先级。本实施例中将第一数据对应的业务称为高优先级业务,将第二数据对应的业务称为低优先级业务。不同优先级业务具有不同的指标要求,相比于低优先级业务,高优先级业务对时延和可靠性有更高的要求,为了满足高优先级业务的指标要求,同时最大限度地保证低优先级业务的性能,需要对不同优先级业务的复用作出规定,目前在非授权频谱中还没有相应的方案可以满足复用的需求。
本申请提供一种数据传输方法,以在第一通信终端和第二通信终端满足传输复用条件下,实现第一通信终端的第一数据与第二通信终端的第二数据的传输复用。
图2为一实施例提供的一种数据传输方法的流程图。如图2所示,本实施例提供的方法包括如下步骤:
步骤201:第一通信终端在目标资源上执行空闲信道评估。
其中,目标资源为第二通信终端暂停或打孔部分第二数据传输对应的目标时域资源,第一通信终端与第二通信终端满足传输复用条件。
步骤202:当确定信道空闲时,第一通信终端在信道上传输第一数据。
本实施例中的第一通信终端和第二通信终端可以是向用户提供语音和/或其他业务数据连通性的设备,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其他处理设备。第一通信终端和第二通信终端可以是移动终端,如 移动电话(或称为“蜂窝”电话)和具有移动终端的计算机,例如,可以是便携式、袖珍式、手持式、计算机内置的或者车载的移动装置,它们与无线接入网交换语言和/或数据。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)等设备。第一节点也可以称为系统、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)、远程终端(Remote Terminal)、接入终端(Access Terminal)、用户终端(User Terminal)、用户代理(User Agent)、用户设备(User Device or User Equipment),在此不作限定。
一实施例中,传输复用条件包括:第一通信终端的信道占用时间(Channel Occupancy Time,简称COT)对应的时域资源与第二通信终端的COT对应的时域资源重叠。
进一步地,传输复用条件还可以包括:第一通信终端的COT对应的频域资源与第二通信终端的COT对应的频域资源重叠。
为了后文描述方便,将“第一通信终端的COT对应的时域资源与第二通信终端的COT对应的时域资源重叠,并且,第一通信终端的COT对应的频域资源与第二通信终端的COT对应的频域资源重叠”定义为第一传输复用子条件。将“第一通信终端的COT对应的时域资源与第二通信终端的COT对应的时域资源重叠,并且,第一通信终端的COT对应的频域资源与第二通信终端的COT对应的频域资源不重叠”定义为第二传输复用子条件。
其中,第一通信终端与第二通信终端在同一个频带传输数据。该频带为通信终端/通信节点执行空闲信道评估的最小频域带宽单位。第二通信终端的COT为第二通信终端执行CCA后获取到的COT,第一通信终端的COT为第一通信终端预占用的COT。
可选地,第一通信终端传输的第一数据的优先级高于第二通信终端传输的第二数据的优先级。
更具体地,第一通信终端的COT为第一通信终端使用基于调度或者免调度资源传输时占用的COT资源。第二通信终端的COT为第二通信终端执行CCA后实际获取到的COT。也即,第一通信终端的COT为预占用的COT而非实际占用的COT,第一通信终端在CCA检测空闲条件下才会实际占用该COT,而第二通信终端的COT为第二通信终端执行CCA检测后实际获取到的COT。
本实施例中的目标时域资源为第二通信终端暂停或打孔部分第二数据传输对应的资源。本实施例中,将第二通信终端暂停或打孔部分第二数据传输称为第二通信终端为第一通信终端预留目标时域资源。即,第二通信终端通过打孔部分时域符号实现预留目标时域资源,也可以通过暂停部分符号上的传输实现预留目标时域资源,在该目标时域资源上,第二通信终端不发送任何数据。第三通信终端不能在目标时域资源上执行空闲信道评估,第三通信终端为传输数据的优先级不高于第二数据的优先级且占用的时频域资源与第二通信终端的COT对应的时频域资源重叠的通信节点。
在步骤201中,第一通信终端可以在需要传输第一数据时,在目标资源上执行CCA,或者,第一通信终端以预设的时间间隔在目标资源上执行CCA,或者,第一通信终端在通信节点或者其他通信终端的指示下,在目标资源上执行CCA。本实施例对此不作限制。
第一种实现方式中,基于调度的第一通信终端与第二通信终端满足上述任一种传输复用子条件时,第一通信终端在第一数据到达后,向通信节点发送调度请求(Scheduling Request,简称SR)。通信节点在接收到SR后,向第一通信终端发送调度上行业务的下行控制信息(Downlink Control Information,简称DCI)。可选地,DCI中可以包括通信节点为第一通信终端分配的传输资源。
本实施例中的通信节点可以是GSM系统或CDMA系统中的基站(Base  Transceiver Station,BTS),也可以是WCDMA系统中的基站(NodeB,NB),还可以是LTE中的eNB,或者中继站或接入点,或者5G系统中的基站等,在此并不限定。
可选地,通信节点可以向第二通信终端发送第一指示信息。第一指示信息用于指示第二通信终端暂停或打孔部分第二数据传输。
需要说明的是,第二通信终端在通信节点的指示为第一通信终端预留目标时域资源只是一种可能的实现方式,还可能存在其他的实现方式。例如,第二通信终端在第一通信终端的指示下预留目标时域资源,或者,第二通信终端根据预配置的规则预留目标时域资源。本实施例对此不作限制。
可选地,通信节点可以向第二通信终端发送第二指示信息。其中,第二指示信息用于指示第二通信终端在第一通信终端传输第一数据的信道上取消数据传输。换句话说,第二指示信息用于指示第二通信终端取消在与第一通信终端的时域资源重叠的资源上传输数据。
需要说明的是,在该实现方式中,通信节点可以只向第二通信终端发送第一指示信息和第二指示信息中的任一种。或者,通信节点将第一指示信息和第二指示信息作为一个指示信息发送给第二通信终端。
在该实现方式中,第一通信终端在自身的传输资源到来前,在第二通信终端预留的目标时域资源上执行CCA,获取相应资源用于传输第一数据。
进一步地,在该实现方式中,在基于调度的第一通信终端与第二通信终端满足第一传输复用子条件时,第一通信终端在第一数据到达后,向通信节点发送SR。通信节点在接收到SR后,向第一通信终端发送调度上行业务的DCI,并向第二通信终端发送第一指示信息和/或第二指示信息。第二指示信息用于指示第二通信终端取消在与第一通信终端的时频域资源重叠的资源上传输数据。第一通信终端在自身的传输资源到来前,在第二通信终端预留的目标时域资源上执行CCA,获取相应资源用于传输第一数据。
第二种实现方式中,免调度的第一通信终端与第二通信终端满足上述任一种传输复用子条件时,目标资源为第二通信终端按照时域资源规则暂停或打孔部分第二数据传输对应的目标时域资源。其中,时域资源规则包括:第二通信终端在第一通信终端的传输资源到来前暂停或打孔部分第二数据传输;或者,第二通信终端在第一通信终端需要在传输资源上传输数据时,在第一通信终端的传输资源到来前暂停或打孔部分第二数据传输。
需要说明的,“第二通信终端在第一通信终端的传输资源到来前暂停或打孔部分第二数据传输”意为不论第一通信终端是否使用其配置授权资源,第二通信终端均为第一通信终端预留目标时域资源。
“第二通信终端在第一通信终端需要在传输资源上传输数据时,在第一通信终端的传输资源到来暂停或打孔部分第二数据传输”意为在第一通信终端使用其配置授权资源的情况下,第二通信终端为第一通信终端预留目标时域资源。
在该实现方式中,第二通信终端也可以在通信节点的指示下预留目标时域资源。
该实现方式中,第一通信终端在信道上以增强后的发射功率发射所述第一数据。相对应地,第二通信终端在第一通信终端发送第一数据的信道上,以降低后的发射功率或者原发射功率发射第二数据。
该实现方式中,第一通信终端增强了第一数据的发射功率,第二通信终端保持或者降低第二数据的发射功率。之后,在第一通信终端在目标时域资源上执行CCA成功后,第一通信终端按照增强后的发射功率发射第一数据,第二通信终端按照原发射功率或者降低后的发射功率发射第二数据。
进一步地,在该实现方式中,在免调度的第一通信终端与第二通信终端满足第一传输复用子条件时,第一通信终端增加第一数据的发射功率,第二通信终端保持或者降低第二数据的发射功率。第二通信终端在第一通信终端发送数据之前预留目标时域资源用于第一通信终端执行CCA。
第三种实现方式中,第一通信终端与第二通信终端满足第二传输复用子条件时,有以下两种方案实现第一数据和第二数据的传输复用。
第一种方案:基于调度的第一通信终端在第一数据到达后,向通信节点发送SR。通信节点在接收到SR后,向第一通信终端发送调度上行业务的DCI,并向第二通信终端发送第一指示信息和/或第二指示信息。第一通信终端在自身的传输资源到来前,在第二通信终端预留的目标时域资源上执行CCA,执行成功后,第一通信终端与第二通信终端占用各自的时频域资源发送业务数据。第一通信终端执行CCA失败后,第二通信终端在预留符号后,继续发送第二通信终端的数据。
图3A为图2所示实施例中第一通信终端及第二通信终端传输数据的一种时频域资源示意图。如图3A所示,一个频带分为10份频域资源,分别将这10份频域资源编号为1至10。图3A中将第二通信终端占用的资源称为低优先级业务资源,将第一通信终端占用的资源称为高优先级业务资源。第二通信终端占用时隙slot n到slot n+3的频域资源1、3、5、7、9用于传输业务。基于调度的第一通信终端从slot n+2开始占用频域资源2、4、6、8、10传输数据。第二通信终端在slot n+1结束位置预留目标时域资源。同时,通信节点指示其他优先级不高于第二通信终端且与第二通信终端时频域资源重叠的第三通信终端不能在slot n+1预留时域资源执行LBT。第一通信终端在所述预留目标时域资源执行LBT,LBT成功后,第二通信终端和第一通信终端分别占用各自的时频域资源传输数据。
第二种方案:基于调度的第一通信终端在第一数据到达后,向通信节点发送SR。通信节点在接收到SR后,向第一通信终端发送调度上行业务的DCI。第一通信终端在通信节点调度的时频域资源到来前,在其所占用的频域资源位置对应的时域资源位置做CCA检测。CCA成功后,第一通信终端使用通信节点分配的时频域资源传输数据,第二通信终端使用自身对应的时频域发送数据。在上述过程中,第二通信终端的业务传输不中断。
图3B为图2所示实施例中第一通信终端及第二通信终端传输数据的另一种时频域资源示意图。如图3B所示,一个频带分为10份频域资源,分别将这10份频域资源编号为1至10。第二通信终端占用时隙slot n到slot n+3的频域资源1、3、5、7、9用于传输业务。基于调度的第一通信终端从slot n+2开始占用频域资源2、4、6、8、10传输数据。第一通信终端在slot n+1结束位置在频域资源2、4、6、8、10对应的时域资源位置执行LBT,第一通信终端执行LBT成功后从slot n+2开始占用频域资源2、4、6、8、10传输数据。
第四种实现方式中,第一传输复用子条件和第二传输复用子条件中的“第一通信终端的COT对应的时域资源与第二通信终端的COT对应的时域资源重叠”具体可以为“第一通信终端的COT对应的时域资源位于第二通信终端的COT对应的时域资源内,且仅与第二通信终端的共享的COT对应的时域资源和/或共享的COT之后对应的时域资源重叠”。在该实现方式中,基于调度的第一通信终端在第一数据到达后,向通信节点发送SR。通信节点在接收到SR后,向第一通信终端发送调度上行业务的DCI。通信节点可以向第二通信终端发送第一指示信息。第一指示信息用于指示第二通信终端为第一通信终端预留目标时域资源,还用于指示第二通信终端限制COT共享的范围。
需要说明的是,在该实现方式中,通信节点也可以只向第二通信终端发送用于指示第二通信终端为第一通信终端预留目标时域资源的指示信息和用于指示第二通信终端限制COT共享的范围的指示信息中的任一个。或者,通信节点在向第二通信终端发送用于指示第二通信终端为第一通信终端预留目标时域资源的指示信息后,再发送另一个指示信息以指示第二通信终端限制COT共享的范围。
图3C为图2所示实施例中第一通信终端及第二通信终端传输数据的又一种时频域资源示意图。如图3C所示,一个频带分为10份频域资源,分别将这10份频域资源编号为1至10。第二通信终端占用时隙slot n到slot n+4的频域资源1、3、5、7、9用于传输业务。第二通信终端将所占用的slot n+2的部分资源、 slot n+3及slot n+4用于COT共享资源。基于调度的第一通信终端从slot n+4开始占用频域资源2、4、6、8、10传输数据。通信节点在收到第一通信终端的SR后发送调度第一通信终端上行业务的DCI,并通知第二通信终端限制COT共享资源。第二通信终端的COT共享资源由原来所占用slot n+2部分资源、slot n+3及slot n+4限制为slot n+2部分资源及slot n+3的部分资源。第一通信终端执行LBT成功后从slot n+4开始占用频域资源2、4、6、8、10传输数据。
需要说明的是,在上述四种实现方式中,通信节点还可以向第三通信终端发送第三指示信息。第三指示信息用于指示第三通信终端不能在目标时域资源上执行CCA。第三通信终端为传输数据的优先级不高于第二数据的优先级且占用的时频域资源与第二通信终端COT对应的时频域资源重叠的通信节点。
在以上四种实现方式中,若第一数据传输和/或第二数据传输包含重复传输,即,同一个传输块(Transport Block,简称TB)的多次传输,两者的复用可以采用以下两种复用方式中的一种。
方式一:若第一通信终端的第一数据传输包含重复传输,则可以将所有重复传输所占的时频域资源视为第一通信终端传输第一数据所占用的时频域资源,对应第一传输复用子条件和第二传输复用子条件,第一通信终端COT对应的时频域资源应该包含所述所有重复传输所占用的时频域资源;与此相同,若第二通信终端的第二数据传输包含重复传输,则第二通信终端COT对应的时频域资源也应该包含所述所有重复传输所占用的时频域资源;然后基于以上定义,执行本实施例提供的步骤201-步骤202,以实现两种业务数据的复用。
方式二:将第一数据的每次重复传输和/或第二数据的重复传输独立看待,然后基于以上四种实现方式处理两者的复用。
第五种实现方式中,目标资源包括为第一数据配置的预留频带对应的资源和除预留频带之外的非预留频带对应的资源。在该实现方式中,第一通信终端和第二通信终端不需要满足传输复用条件。
在一个带宽下,带宽内的频域资源可以分为多个频带,NR-U设备以频带为单位执行LBT。LBT成功后可以占用相应的COT传输数据。为了满足高优先级业务的指标需求,可以单独为高优先级业务预留1个或者多个频带,所述预留频带仅用于高优先级业务传输。非预留频带可以同时支持高优先级业务和低优先级业务传输。所述预留频带与非预留频带相比,可能具有更多的LBT机会。
在该实现方式中,第一通信终端在预留频带对应的资源和非预留频带对应的资源上均执行空闲信道评估。
当第一通信终端在其中一种频带对应的资源上执行CCA成功,则选择CCA成功的频带的COT用于传输数据。
当确定预留频带对应的资源上的信道以及非预留频带对应的资源上的信道均空闲时,第一通信终端根据频带选取规则,选取目标频带对应的资源上的信道传输第一数据。其中,频带选取规则包括以下任意一种:将预留频带作为目标频带;将非预留频带作为目标频带;将预留频带以及非预留频带中信道质量最好的频带作为目标频带;将预留频带以及非预留频带的组合频带作为目标频带。组合频带可以仅包含预留频带、仅包含非预留频带或同时包含预留频带和非预留频带。
本实施例提供的数据传输方法,通过第一通信终端在目标资源上执行空闲信道评估,其中,目标资源为第二通信终端暂停或打孔部分第二数据传输对应的目标时域资源,第一通信终端与第二通信终端满足传输复用条件,当确定信道空闲时,第一通信终端在信道上传输第一数据,在第一通信终端和第二通信终端满足传输复用条件下,实现第一通信终端的第一数据与第二通信终端的第二数据的传输复用,提高了频谱资源的利用率。
