Description

一种通信方法及装置 技术领域
本申请涉及通信领域,尤其涉及一种通信方法及装置。
背景技术
随着移动互联网和物联网产业的发展,越来越多的移动终端相互连接并分享更加丰富的数据。物联网设备具有成本低、易部署以及免维护等特点。相对于授权频谱,物联网设备在非授权频谱上传输数据,能够有效降低网络成本。
非授权频谱物联网(Internet of Things on unlicensed spectrum,IoT-U)是工作在非授权频谱上的一种物联网窄带通信技术。其主要目的是实现长距离、低成本、低功耗的物联网通信。其上行发送采用非自适应跳频,主要工作频点是Sub 1GHz,也可以扩展到其他非授权频谱上。
由于频谱是无线通信的基础,为了保证对频谱的公平使用,各个国家制定了不同的法律规则。为了避免物联网设备在非授权频谱上无规律,无限制的发送数据,通信委员会在非授权频谱上规定了不同的认证法规,其中,可包括跳频认证、数字调制认证以及跳频认证与数字调制认证相混合的混合认证等。
蓝牙通信就是采用跳频通信认证的,其发射机载波跳频的顺序由伪随机的跳频序列来确定,每个微微网(Piconet)都有唯一的一个跳频序列。蓝牙采用2.4GHz的工业科学医学(industrial scientific medical,ISM)频段,从2.402GHz到2.480GHz划分为79个信道(每个信道的带宽为1MHz),平均速率为1600跳/秒。
其中,与跳频通信认证相对应的数字调制认证,当物联网设备采用数字调制认证时,物联网设备如何与网络设备进行通信,并没有广泛使用的解决方案。

具体实施方式
下面结合附图,对本申请实施例进行介绍。
如图1所示,本申请实施例提供一种通信系统100,该通信系统100可包括网络设备101和终端设备102。
其中,通信系统100,可以采用各种无线接入技术(radio access technology,RAT),例如码分多址(code division multiple access,CDMA)、时分多址(time division multiple access,TDMA)、频分多址(frequency division multiple access,FDMA)、正交频分多址(orthogonal frequency-division multiple access,OFDMA)、单载波频分多址(single carrier FDMA,SC-FDMA)等,本申请对通信系统所采用的RAT不做限定。在本申请中,术语“系统”可以和“网络”相互替换。
网络设备101可以是网络中将终端设备接入到无线网络的设备。所述网络设备为无线接入网中的节点,又可以称为基站,还可以称为无线接入网(radio access network,RAN)节点(或设备)。目前,一些网络设备的举例为:gNB、传输接收点(transmission reception point,TRP)、演进型节点B(evolved Node B,eNB)、家庭基站(例如,home evolved NodeB,或home Node B,HNB)、基带单元(base band unit,BBU),或WiFi接入点(access point,AP)等。另外,在一种网络结构中,所述网络设备可以包括集中单元(centralized unit, CU)节点和分布单元(distributed unit,DU)节点。这种结构将长期演进(long term evolution,LTE)系统中eNB的协议层拆分开,部分协议层的功能放在CU集中控制,剩下部分或全部协议层的功能分布在DU中,由CU集中控制DU。
终端设备102,又称之为用户设备(user equipment,UE)、移动台(mobile station,MS)、移动终端(mobile terminal,MT)等,是一种向用户提供语音和/或数据连通性的设备,例如,具有无线连接功能的手持式设备、车载设备等。目前,一些终端的举例为:手机(mobile phone)、平板电脑、笔记本电脑、掌上电脑、移动互联网设备(mobile internet device,MID)、可穿戴设备,虚拟现实(virtual reality,VR)设备、增强现实(augmented reality,AR)设备、工业控制(industrial control)中的无线终端、无人驾驶(self driving)中的无线终端、远程手术(remote medical surgery)中的无线终端、智能电网(smart grid)中的无线终端、运输安全(transportation safety)中的无线终端、智慧城市(smart city)中的无线终端、智慧家庭(smart home)中的无线终端等。
其中,网络设备101与终端设备102可工作在授权频段上,也可工作在非授权频段上,比如所述非授权频段可包括902-928MHz,2400-2483.5MHz和5725-5850MHz等。为了避免通信设备在非授权频段上无规律,无限制的发送数据,通信委员会规定了不同的认证法规,比如,跳频认证(frequency hopping systems(,FHSs)、数字调制认证(digital transmission systems,DTSs)以及跳频认证与数据调制认证相混合的混合认证(Hybird)等。在DTSs认证中,主要法规需求有信道带宽、最大发送功率、邻道功率泄露等指标,具体如下:
法规要求在数字调制digital modulation,DM)模式下,信道带宽大于500KHz;不能发送无用信息(garbage);信道带宽必须占用宣称的带宽,某个时刻实际使用带宽小于宣称带宽会被质疑,如果被联邦通讯委员会(federal communications commission,FCC)判定不符合法规,则对应的通讯产品无法进行销售,合规性是产品解决方案的首要条件。
基于以上,如图2所示,本申请提供一种通信方法,该通信方法可满足DTSs法规要求。该通信方法中的网络设备可为图1中的网络设备101,终端设备可为图1中的终端设备102。可以理解的是,在本申请实施例中,网络设备的功能也可以通过应用于网络设备的芯片来实现,终端设备的功能也可以通过应用于终端设备的芯片来实现。该流程具体为:
S201:网络设备确定第一信道。
其中,所述第一信道在频域上可占用3个物理资源块(physical resource block,PRB),第一信道占用的时域资源为20ms。3个PRB可分别为第一PRB、第二PRB以及第三PRB,每个PRB在频域上可占用180kHz带宽,所述第一PRB可为公共信道的同步和广播占用,第二PRB可为下行数据信道占用,可传输物理下行数据信道(physical downlink shared channel,PDSCH)和物理下行控制信道(physical downlink control channel,PDCCH)。第三PRB可为公共信道的系统消息,比如系统消息块(system information blocks,SIB)等。需要说明的是,在本申请实施例中,上述第一PRB、第二PRB以及第三PRB,仅为区分三个PRB,并不作为对本申请的限定。第一、第二、第三可为三个PRB的索引,所述索引可以从1开始编号,分别为第一PRB、第二PRB以及第三PRB等,所述索引也可从0开始编号,分别为PRB#0、PRB#1以及PRB#2等。
S202:网络设备利用所述第一信道,发送第一信息。
其中,所述第一信息中至少包括同步信号、主信息块(master information block,MIB)、第一下行信息以及系统消息,所述第一PRB可用于承载所述同步信号以及广播信道,所述 广播信道上承载有所述MIB,所述第二PRB可用于承载所述第一下行信息,所述第一下行信息中可包括下行数据信息和下行控制信息中的至少一个。所述第三PRB块可用于承载所述系统消息。
S203:终端设备利用第一信道,接收第一信息。
在本申请实施例中,终端设备可首先在所述第一PRB上检测所述同步信号,终端设备在检测到所述同步信号后,可在所述第一PRB上接收主信息块,且对所述主信息块进行处理;在对所述主信息块处理完成时,可在所述第三PRB上接收系统消息,且对所述系统消息进行处理;在对所述系统消息处理完成时,可在所述第二PRB上接收所述第一下行信息。
在本申请的一示例中,网络设备可按照第一周期,在所述第一信道中周期性向所述终端设备发送所述第一信息,不同周期发送的所述第一信息中的内容相同或不同,所述第一周期可但不限于为80ms。相应的,终端设备可按照第一周期,在所述第一信道上周期性接收所述第一信息。
在本申请实施例中,所述第一信道还可称为锚信道(anchor信道),或者锚部分(anchor segment)。
需要理解的是,在本申请的描述中,“第一”、“第二”等词汇,仅用于区分描述的目的,而不能理解为指示或暗示相对重要性,也不能理解为指示或暗示顺序。
基于以上,如图3所示,本申请提供一种通信方法,该通信方法中的网络设备可为图1中的网络设备101,终端设备可为图1中的终端设备102。该流程具体为:
S301:网络设备确定第二信道。
其中,第二信道还可称为数据部分(data segment),所述第二信道在频域上可占用1个PRB,占用的时域资源为60ms,所述第二信道在时域上可包多个n帧(nframe),针对每个nframe,可包括N个子帧(subframe),所述N为正整数。比如,第二信道占用的时域资源可为3个nframe,每个nframe在时域上可包括20个子帧(subframe),每个subframe在时域上占用1ms。
S302:网络设备发送上行子帧与下行子帧的配比,所述上行子帧与下行子帧的配比指所述第二信道中用于上行数据传输的子帧与用于下行数据传输的子帧的比值;
比如,在本申请实施例中,针对任一nframe,所述上行子帧与下行子帧的配比可为N,即该nframe中的所有子帧全部用于上行,终端设备可在第二信道所包括的N个子帧上,发送上行数据,相应的,网络设备可在第二信道所包括的N个子帧上,接收上行数据。
S303:终端设备接收上行子帧与下行子帧的配比。
S304:网络设备根据所述上行子帧与下行子帧的配比,基于所述第二信道与所述终端设备进行数据传输。
在本申请实施例中,网络设备可根据所述上行子帧与下行子帧的配比,基于第二信道与终端设备进行上行数据传输和下行数据传输中的至少一个。如果所述子帧被全部分配用于上行,那么网络设备可基于第二信道与终端设备进行上行数据传输,如果所述子帧被全部分配用于下行,那么网络设备可基于第二信道与终端设备进行下行数据传输,如果所述子帧一部分被分配用于上行,另一部分被分配用于下行,那么网络设备可基于第二信道,与终端设备同时进行上行数据传输和下行数据传输。
需要说明的是,图3所示的流程图,可单独应用,也可与图2所示的流程图结合使用,在此不作限定。
如图4所示,第一信道占用的时域资源可称为anchor segment,anchor segment的取值可为20ms,第二信道占用的时域资源可称为data segment,data segmentr的取值可为60ms,achor segment与data segment在时域上相邻。
如图5所示,在时域,anchor segment的周期可为80ms,anchor部分可由开始的两个无线帧(radio frame)组成,data segment可由剩余的六个无线帧组成,每个无线帧在时域上占用10ms。
如图6所示,在频域,anchor segment可由3个PRB组成,为了方便描述,可将3个PRB称为nPRB#0,nPRB#1,以及nPRB#2等。每个PRB均占用频域180kHz带宽,nPRB#0为低频频段,nPRB#1占用与nPRB#0相邻的高频位置180kHz,nPRB#2占用与nPRB#1相邻的高频位置180khz,或者n PRB#0为高频频段,nPRB#1占用与nPRB#0相邻的低频位置180kHz,nPRB#2占用与nPRB#1相邻的低频位置180kHz等。
在本申请实施例中,anchor segment可仅用于下行数据传输。终端设备可假设anchor segment用于传输同步信号、物理广播信道、物理下行控制信道和物理下行数据信道。
在时域,data segment可包括3个nframe,每个nframe可占用20ms。每个nframe可包括20个子帧,每个子帧可占用1ms。nframe可用于上行传输和下行数据的至少一个,可用上行/下行传输配比控制segment data的上下行传输。
如表1所示,本申请提供一种上行/下行传输配比(Uplink-downlink configuration)的示例,在该示例中,以Nframe为示例进行说明。在本申请实施例中,一个Nframe中可包括20个子帧,索引号为0至19。在本申请实施例中,0至19个子帧可均用于上行数据传输,也可均用于下行数据传输,也可同时用于上行数据传输和下行数据传输。具体的,在表1所示的示例中,“D”可代表一子帧用于下行数据传输,“U”可代表一子帧用于上行数据传输,“S”可表示该子帧为包括DwPTS和GP(Guard Period)两个部分的特殊子帧。比如,在表1中,在索引号为0的Nframe中子帧0至子帧4可用于下行数据传输,子帧5可用作包括DwPTS和GP两个部分的特殊子帧,子帧6至子帧19可用于上行数据传输。索引号为4的Nframe中,子帧0至子帧19均用于上行数据传输。

采用本申请实施例所公开的方法,在满足数据调制认证的法规前提下,可拥有更多可用的下行数据传输资源,且可有更低的时延。已知频点上接收同步信号,不需要FHSs认证的盲检;更多的数据资源元素,anchor部分占用3个PRB,其中中间位置的PRB仍可以作为数据来使用,而FHSS认证,在anchor部分无法传输数据资源元素。
