Description

共享频谱上的数据传输方法、设备和系统 技术领域
本发明的实施例涉及通信系统,尤其是涉及一种共享频谱上的数据传输方法、设备和系统。
背景技术
频谱资源是无线通信的基础,非授权(unlicensed)频谱资源要大于授权频谱资源。目前,未授权频谱上使用的主要技术是无线保真(Wireless Fidelity,WiFi),但是WiFi在移动性、安全性、服务质量(Quality of Service,QoS)、以及同时处理多用户调度方面存在缺陷,因此,将长期演进(Long-term Evolution,LTE)设备应用在非授权频谱,不仅可以有效利用非授权频谱资源,还可以提供更为有效的无线接入、满足日益增长的移动宽带服务的需求。
由于非授权频谱上对无线通信系统和运营商使用没有约束,非授权频谱为共享频谱,即存在多种通信系统的多个运营商都想要占用相同频谱的情况。无线通信设备在未授权频谱上使用时需要遵循特定的法规规则,例如欧洲电信标准协会(European Telecommunications Standards Institute,ETSI)发布的ETSI EN 301893中对未授权频谱使用时规定了先听后说(Listen Before Talk,LBT)、信道带宽占用需求等规则。根据LBT规则,设备在使用信道之前,首先监听信道是否空闲,如果信道空闲则可以使用该非授权频谱上的信道。
对于长期演进(Long Term Evolution,LTE)通信系统,基站(evolvedNodeB,eNB)和用户设备(User Equipment,UE)进行上行数据的传输时,基站需要发送控制信息给用户设备,用户设备则根据所述控制信息向基站发送数据以完成上行数据的传输。从基站发送控制信息给用户设备到用户设备根据所述控制信息向基站发送数据需要一定的时间间隔。当所述基站和所述用户设备利用非授权频谱进行上行数据传输时,用户设备先要根据LBT原则对非授权频谱进行监听,当监听到非授权频谱空闲时,用户设备才可以占用该非授权频谱根据所述控制信息向基站进行上行数据的发送。如果所述用户设备在所述时间间隔内没有监听到所述非授权频谱空闲,即监听到所述非授权频谱被占用,所述用户设备无法在所述时间间 隔内占用所述非授权频谱,而此时基站也无法知晓所述用户设备没有占用到所述非授权频谱,则所述用户设备无法根据所述控制信息完成上行数据的发送。
因此,一方面,基站给用户设备发送控制信息是一种无效的发送;另一方面,基站为用户设备分配的频谱资源不会同时分配给其他用户设备,从而造成频谱利用效率低的缺陷。

具体实施方式
下面将结合本发明实施例中的附图,对本发明实施例中的技术方案进行清楚、完整地描述,显然,所描述的实施例是本发明一部分实施例,而不是全部的实施例。基于本发明中的实施例,本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例,都属于本发明保护的范围。
图1是本发明实施例的系统的示意性架构图。
本发明实施例提供的基站可以为UMTS下的基站(Node B,NB)、LTE下的演进型基站(eNodeB,eNB)或者第五代移动通信系统下的基站或控制器。
本发明实施例提供的用户设备(User Equipment,UE)可以是但不限于移动台(MS,Mobile Station)、移动终端(Mobile Terminal)、移动电话(Mobile Telephone)、手机(handset)及便携设备(portable equipment)等。
本发明实施例的共享频谱为非授权频谱。可选的,本发明实施例的共享 频谱为运营商或者某些机构购买的授权频谱,并将此授权频谱共享使用。
本发明实施例用于上行数据的传输,基站发送控制信息给用户设备,用户设备根据控制信息发送数据,基站根据控制信息来接收数据。
本发明实施例基于上述系统架构,需要说明的是,在不冲突的情况下,各个实施例以及实施例中的特征可以相互结合。
图2为本发明实施例提供的共享频谱上的数据接收方法,其步骤包括:
步骤21,基站发送第一控制信息给用户设备。所述第一控制信息为用户设备发送数据的调度指示信息。可选的,所述第一控制信息包括数据的传输格式、调制编码方式、预编码信息、数据传输所占资源的资源分配信息等。在可选的实施例中,所述第一控制信息还包含有效时间指示信息,所述有效时间指示信息用于指示所述第一控制信息的有效的时间范围,即所述第一控制信息是预调度控制信息。
步骤22,所述基站从所述用户设备接收第一指示信息。其中,所述第一指示信息用于指示所述用户设备能够占用共享频谱。用户设备根据共享频谱的使用规则判断是否能够占用所述共享频谱。例如用户设备根据LBT规则对共享频谱进行监听,按照LBT规则判定用户是否能够占用所述共享频谱。其中LBT法则的具体内容以及利用LBT法则判断的具体步骤不作限定。如果所述用户设备判定能够占用所述共享频谱,然后,用户设备再发送第一指示信息以指示基站所述用户设备能够占用共享频谱。
步骤23,所述基站根据所述第一指示信息向所述用户设备发送第二指示信息。其中,所述第二指示信息用于指示所述用户设备,在所述共享频谱按照所述第一控制信息向所述基站发送数据的设备为所述用户设备。当基站接收到用户设备发送的指示所述用户设备能够占用共享频谱的第一指示信息后,基站根据第一指示信息可以确定所述用户设备占用到了共享频谱,并发送第二指示信息以指示所述用户设备在所述共享频谱按照所述第一控制信息向所述基站发送数据的设备为所述用户设备。
步骤24,所述基站根据所述第二指示信息和所述第一控制信息从所述用户设备接收第一数据。
通过上述方案,基站为所述用户设备预先配置了发送数据的第一控制信息。基站从所述用户设备接收第一指示信息,所述第一指示信息用于指示所述用户设备能够占用共享频谱,所述基站根据所述第一指示信息向所述用户 设备发送第二指示信息,所述第二指示信息用于指示所述用户设备,在所述共享频谱按照所述第一控制信息向所述基站发送数据的设备为所述用户设备,由此,用户设备可以通知基站是否能够占用共享频谱,而基站也可以通知用户设备根据第一控制信息来完成上行数据的发送,由此,避免了基站无法知晓用户设备是否占用共享频谱,并无法控制用户设备是否占用共享频谱按照第一控制信息的指示发送数据,提高了共享频谱的利用效率。
在可选的实施例中,在所述基站从所述用户设备接收第一指示信息的同时,所述基站还从其它用户设备接收第四指示信息,所述第四指示信息用于指示所述其它用户设备能够占用共享频谱;在所述基站还从其它用户设备接收第四指示信息之后,所述基站向所述其它用户设备发送第五指示信息,所述第五指示信息用于指示所述其它用户设备,在所述共享频谱按照所述第一控制信息向所述基站发送数据的设备不是所述其它用户设备。对于具有两个以上用户设备的情况,如果所述用户设备和其它用户设备都对共享频谱进行监听并检测到共享频谱的信道空闲,则所述用户设备会向基站发送第一指示信息以指示所述用户设备能够占用共享频谱,所述其它用户设备也会向基站发送第四指示信息以指示所述其它用户设备能够占用共享频谱。此时,基站会向所述用户设备发送第二指示信息,基站还会向所述其它用户设备发送第五指示信息,所述第二指示信息以及所述第五指示信息都是用于通知用户设备是否可以按照第一控制信息进行数据的发送,同时,基站也会根据第二指示信息以及所述第五指示信息来接收所述用户设备的上行数据,而不接收所述其它用户设备的数据。当然,此时由于所述其它用户设备接收到的第五指示信息是用于指示所述其它用户设备在所述共享频谱按照所述第一控制信息向所述基站发送数据的设备不是所述其它用户设备,因此,所述其它用户设备不会按照第一控制信息的指示向所述基站发送数据。通过本实施例,基站可以对多个用户设备进行调度以指示哪个用户设备可以占用共享频谱按照第一控制信息的指示发送上行数据,解决了多个用户设备的第一控制信息所指示的共享频谱的资源有重叠的情况下,多个用户同时在共享频谱上发送数据产生的冲突问题,提高了共享频谱的利用效率。
在可选的实施例中,在所述基站从所述用户设备接收第一指示信息之前,所述基站发送第三指示信息给所述用户设备,所述第三指示信息用于指示所述第一控制信息有效的时间范围。可选的,所述第一控制信息的有效时 间为X ms,其中X为大于0的数值,例如,所述第一控制信息的有效时间为10ms。利用第三指示信息来指示第一控制信息的有效范围,可以使基站根据信道质量以及业务需求来及时调整第一控制信息的内容,以提高共享频谱使用的灵活性。
在可选的实施例中,所述基站根据所述第一指示信息向所述用户设备发送第二指示信息具体为所述基站在n时刻根据所述第一指示信息向所述用户设备发送第二指示信息,所述第二指示信息用于指示所述用户设备,在所述共享频谱根据所述第一控制信息向所述基站发送数据的设备为所述用户设备具体为所述第二指示信息用于指示所述用户设备从n+t时刻开始,在所述共享频谱按照所述第一控制信息向所述基站发送数据的设备为所述用户设备,所述基站根据所述第二指示信息和所述第一控制信息从所述用户设备接收第一数据具体为所述基站按照所述第二指示信息和所述第一控制信息从所述用户设备接收所述用户设备从所述n+t时刻开始发送的所述第一数据,其中,所述t为预设的时间长度。
在可选的实施例中,所述基站确定所述用户设备发送所述第一数据的停止时刻,其中,所述停止时刻为n+t+v,所述v为预设的时间长度、所述第二指示信息中携带所述v的值、或所述停止时刻由所述基站根据第六指示信息确定,其中所述第六指示信息为所述用户设备发送给所述基站以指示所述用户设备发送完毕所述第一数据。
在可选的实施例中,所述基站确定所述用户设备发送所述第一数据的停止时刻,其中,所述停止时刻为n+w,所述w为预设的时间值、所述第二指示信息中携带所述w的值、或所述停止时刻由所述基站根据第六指示信息确定,其中所述第六指示信息为所述用户设备发送给所述基站以指示所述用户设备发送完毕所述第一数据。
在可选的实施例中,如果所述第一控制信息的有效范围在所述用户设备从所述n+t时刻开始发送所述第一数据到所述n+t+v停止发送期间,即所述第一控制信息在n+t+u时刻失效(u<v),则所述用户设备在n+t+u时刻到所述n+t+v时刻之间用更新的第一控制信息发送第一数据,同时基站根据所述更新的第一控制信息接收第一数据。在可选的实施例中,所述基站发送第二控制信息给所述用户设备,所述第二控制信息包括数据的传输格式、调制编码方式、预编码信息、数据传输所占资源的资源分配信息等;在所述基站从 所述用户设备接收第一指示信息之后,在接收所述用户设备从所述n+t时刻开始发送的所述第一数据之前,所述基站根据所述第二控制信息从所述用户设备接收第二数据。在所述基站从所述用户设备接收第一指示信息之后,在接收所述用户设备从所述n+t时刻开始发送的所述第一数据之前,所述用户设备无法根据所述第一控制信息向基站发送上行数据,则此段时间内如果所述用户设备发送的用于占用所述共享频谱的第一信号中不携带有效数据信息,共享频谱是被浪费了,因此,通过所述基站发送第二控制信息给所述用户设备,在所述基站从所述用户设备接收第一指示信息之后,在接收所述用户设备从所述n+t时刻开始发送的所述第一数据之前,所述基站按照所述第二控制信息从所述用户设备接收第二数据,由此,利用了在所述基站从所述用户设备接收第一指示信息之后,在接收所述用户设备从所述n+t时刻开始发送的所述第一数据之前这段时间,提高了共享频谱的利用效率。
在可选的实施例中,基站为不同用户设备分别发送的第二控制信息,所述第二控制信息所指示的数据传输所占资源之间是正交的。
在可选的实施例中,所述第二指示信息还用于指示所述基站停止根据所述第二控制信息从所述用户设备接收所述第二数据。可选的,当基站向用户设备发送第二指示信息时,基站即停止接收所述第二数据,以做好准备根据第一控制信息接收所述第一数据。可选的,所述第二指示信息包含一个时间指示信息,此时间指示信息用于指示停止接收所述用户设备按照所述第二控制信息从所述n+t时刻开始发送的所述数据。
在可选的实施例中,所述第一指示信息或所述第二指示信息或第四指示信息或第五指示信息由预设序列承载或由物理控制信道承载。可选的,所述预设序列为恒包络零自相关(Constant Amplitude Zero Auto Correlation,CAZAC)序列。基站为用户设备分别预配置所述用于承载第一指示信息的CAZAC序列和用于承载第四指示信息的CAZAC序列,同时向所述用户设备配置分别用于承载第二指示信息的CAZAC序列和用于承载第五指示信息的CAZAC序列。可选的,所述承载第一指示信息或所述第二指示信息或第四指示信息或第五指示信息的预设序列在时间上占用一个OFDM符号。可选的,所述第一指示信息或第四指示信息由上行物理控制信道(PUCCH)承载。可选的,所述第二指示信息或第五指示信息由下行物理控制信道(PDCCH)或增强下行物理控制信道(EPDCCH)承载。可选的,所述第二 指示信息和第五指示信息在同一(增强)物理下行控制信道中承载。例如基站在(增强)物理下行控制信道的公共搜索空间内通过PDCCH或EPDCCH发送为所述用户设备发送的第二指示信息和为所述其他用户设备发送的第五指示信息。所述用户设备和所述其他用户设备分别从所述PDCCH或EPDCCH中读取第二指示信息或第五指示信息。针对不同的用户设备,其在所述PDCCH或EPDCCH中读取第二指示信息或第五指示信息的位置是预设的。
在可选的实施例中,所述第一指示信息或所述第二指示信息或第四指示信息或第五指示信息可以通过共享频谱发送。
在可选的实施例中,所述共享频谱为不同无线通信运营商运营的无线通信系统或者不同的无线通信系统可以共享的频谱。可选的,所述共享频谱为非授权频谱。
图3为本发明实施例提供的一种基站,用于执行图2实施例所述的方法,此基站包括发送单元301和接收单元302。
所述发送单元301,用于发送第一控制信息给用户设备。所述第一控制信息为用户设备发送数据的调度指示信息。可选的,所述第一控制信息包括数据的传输格式、调制编码方式、预编码信息、数据传输所占资源的资源分配信息等。所述第一控制信息与图2实施例一致,不再赘述。
所述接收单元302,用于从所述用户设备接收第一指示信息。其中,所述第一指示信息用于指示所述用户设备能够占用共享频谱。用户设备根据共享频谱的使用规则判断是否能够占用所述共享频谱。例如用户设备根据LBT规则对共享频谱进行监听,按照LBT规则判定用户是否可以占用所述共享频谱。其中LBT法则的具体内容以及利用LBT法则判断的具体步骤不作限定。如果所述用户设备判定可以占用所述共享频谱,然后,用户设备再发送第一指示信息以指示基站所述用户设备能够占用共享频谱。
所述发送单元301,还用于根据所述第一指示信息向所述用户设备发送第二指示信息。其中,所述第二指示信息用于指示所述用户设备,在所述共享频谱按照所述第一控制信息向所述基站发送数据的设备为所述用户设备。当基站接收到用户设备发送的指示所述用户设备能够占用共享频谱的第一指示信息后,基站根据第一指示信息可以确定所述用户设备占用到了共享频谱,并发送第二指示信息以指示所述用户设备在所述共享频谱根据所述第一 控制信息向所述基站发送数据的设备为所述用户设备。
所述接收单元302,还用于根据所述第二指示信息和所述第一控制信息从所述用户设备接收第一数据。
通过上述方案,基站为所述用户设备预先配置了发送数据的第一控制信息。基站从所述用户设备接收第一指示信息,所述第一指示信息用于指示所述用户设备能够占用共享频谱,所述基站根据所述第一指示信息向所述用户设备发送第二指示信息,所述第二指示信息用于指示所述用户设备,在所述共享频谱按照所述第一控制信息向所述基站发送数据的设备为所述用户设备,由此,用户设备可以通知基站是否能够占用共享频谱,而基站也可以通知用户设备根据第一控制信息来完成上行数据的发送,由此,避免了基站无法知晓用户设备是否占用共享频谱,并无法控制用户设备是否占用共享频谱按照第一控制信息的指示发送数据,提高了共享频谱的利用效率。
在可选的实施例中,在所述接收单元302从所述用户设备接收第一指示信息的同时,所述接收单元302还从其它用户设备接收第四指示信息,所述第四指示信息用于指示所述其它用户设备能够占用共享频谱;在所述接收单元302还从其它用户设备接收第四指示信息之后,所述发送单元301向所述其它用户设备发送第五指示信息,所述第五指示信息用于指示所述其它用户设备,在所述共享频谱按照所述第一控制信息向所述基站发送数据的设备不是所述其它用户设备。对于具有两个以上用户设备的情况,如果所述用户设备和其它用户设备都对共享频谱进行监听并检测到信道空闲,则所述用户设备会向基站发送第一指示信息以指示所述用户设备能够占用共享频谱,所述其它用户设备也会向基站发送第四指示信息以指示所述其它用户设备能够占用共享频谱。此时,基站会向所述用户设备发送第二指示信息,基站还会向所述其它用户设备发送第五指示信息,所述第二指示信息以及所述第五指示信息都是用于通知用户设备是否可以按照第一控制信息进行数据的发送,同时,基站也会根据第二指示信息以及所述第五指示信息来接收所述用户设备的上行数据,而不接收所述其它用户设备的数据。当然,此时由于所述其它用户设备接收到的第五指示信息是用于指示所述其它用户设备在所述共享频谱根据所述第一控制信息向所述基站发送数据的设备不是所述其它用户设备,因此,所述其它用户设备不会向所述基站发送数据。通过本实施例,基站可以对多个用户设备进行调度以指示哪个用户设备可以占用共享频谱 发送上行数据,解决了多个用户设备的第一控制信息所指示的共享频谱的资源有重叠的情况下,多个用户同时在共享频谱上发送数据产生的冲突问题,提高了共享频谱的利用效率。

在可选的实施例中,所述用户设备从所述基站接收第二控制信息;在所述用户设备向所述基站发送第一指示信息之后,所述用户设备接收所述基站根据所述第一指示信息发送的第二指示信息之前,所述用户设备根据所述第二控制信息向所述基站发送第二数据。在所述用户设备向所述基站发送第一指示信息之后,所述用户设备接收所述基站根据所述第一指示信息发送的第二指示信息之前,所述用户设备无法根据所述第一控制信息向基站发送上行数据,则此段时间内如果所述用户设备发送的用于占用所述共享频谱的第一信号中不携带有效数据信息,共享频谱是被浪费了,因此,通过所述用户设备从所述基站接收第二控制信息,在所述用户设备向所述基站发送第一指示信息之后,所述用户设备接收所述基站根据所述第一指示信息发送的第二指示信息之前,所述用户设备根据所述第二控制信息向所述基站发送第二数据,由此,在所述用户设备向所述基站发送第一指示信息之后,所述用户设备接收所述基站根据所述第一指示信息发送的第二指示信息之前这段时间,利用了共享频谱发送有效数据,提高了共享频谱的利用效率。
在可选的实施例中,所述第二指示信息还用于指示所述用户设备停止发送所述第一信号或所述第二数据。由此,避免了第一信号或者第二数据对其它用户第一数据的干扰。
在可选的实施例中,基站为不同用户设备分别发送的第二控制信息,所述第二控制信息所指示的数据传输所占资源之间是正交的。避免了所述不同用户同时按照第二控制信息发送数据时互相之间的干扰。

在可选的实施例中,在所述用户设备从基站接收第一控制信息之后,且在所述用户设备向所述基站发送第一指示信息之前,所述用户设备对所述共享频谱进行检测以生成所述第一指示信息。
在可选的实施例中,所述共享频谱为不同无线通信运营商运营的无线通信系统或者不同的无线通信系统可以共享的频谱。可选的,所述共享频谱为非授权频谱。

通过上述方案,此时由于所述用户设备接收到的第二指示信息是用于指 示所述用户设备在所述共享频谱根据所述第一控制信息向所述基站发送数据的设备不是所述用户设备,因此,所述其它用户设备不会按照第一控制信息向所述基站发送数据。通过本实施例,基站可以对多个用户设备进行调度以指示哪个用户设备可以占用共享频谱发送上行数据,解决了多个用户设备的第一控制信息所指示的共享频谱的资源有重叠的情况下,多个用户同时在共享频谱上发送数据产生的冲突问题,提高了共享频谱的利用效率。

在可选的实施例中,所述第二指示信息还用于指示所述发送单元702停止发送所述第一信号或所述第二数据。由此,避免了第一信号或者第二数据对其它用户第一数据的干扰。
在可选的实施例中,基站为不同用户设备分别发送的第二控制信息,所述第二控制信息所指示的数据传输所占资源之间是正交的。避免了所述不同用户同时按照第二控制信息发送数据时互相之间的干扰。

步骤82,UE1根据LBT法则对共享频谱监听。
步骤83,UE2根据LBT法则对共享频谱监听。可选的,步骤81、82、83的顺序不作限定。
假如,在步骤82和步骤83中,UE1和UE2都监听到所述共享频谱空闲。
步骤84,UE1向基站发送第一指示信息,所述第一指示信息用于指示UE1占用到了所述共享频谱。其中,如图9所示,图8所示的步骤84的第一指示信息由UE1发送并由基站在n时刻接收到。
