Description
本发明涉及通信领域,具体而言,涉及一种非授权载波的载波资源处理方法、装置及传输节点。
截止目前,众所周知长期演进(Long-Term Evolution,简称为LTE)是部署在授权载波中运营的。但是随着数据业务的快速增长,在不久的将来,授权频谱将不能再承受下如此巨大的数据量。因此,在非授权频谱中部署LTE,通过非授权频谱来分担授权载波中的数据流量,是后续LTE发展的一个重要的演进方向。
另外,对于非授权频谱,也是存在很多优势的:免费/低费用(不需要购买非频谱,频谱资源为零成本);准入要求低,成本低(个人、企业都可以参与部署,设备商的设备可以任意);共享资源(多个不同系统都运营其中时或者同一系统的不同运营商运营其中时,可以考虑一些共享资源的方式,提高频谱效率);无线接入技术多(跨不同的通信标准,协作难,网络拓扑多样);无线接入站点多(用户数量大,协作难度大,集中式管理开销大);应用多(从资料看,多业务被提及可以在其中运营,例如,机器到机器(Machine to machine,简称为M2M)、车辆到车辆(Vehicle to vehicle,简称为V2V)。
但是对于非授权频谱,会有多个系统也工作在相同的频谱上,如WIFI系统。因此,系统(例如,LTE系统)工作在非授权频谱(或称非授权载波)上,解决与其他系统共存所涉及到的问题是至关重要的。
因此,在相关技术中,系统工作在非授权载波上时,存在与其它系统共存涉及到的问题。

在传输窗内以竞争的方式确定接入非授权载波时,可以采用以下处理方式:在传输窗[0,Y]内生成k个随机数N0,N1,…Nk-1,其中,Nj为第j次接入非授权载波的起始时刻,0<j<=k-1,k的取值依据用于传输的数据量和每次接入非授权载波所占用的时间确定,Y的取值依据传输窗长度确定;在从Nj时刻检测到干净信道评估CCA长度的空闲时,在Nj时刻开始进行第j次接入非授权载波。即Nj作为第一系统对应的传输节点第j次接入的起始时刻是指LTE-U站点从Nj时刻开始检测非授权载波的状态,检测到干净信道评估(Clear Channel Assessment,简称为CCA)长度的空闲,第一系统对应的传输节点进行第j次接入;其中CCA的长度小于等于50us。
在本发明实施例中,在传输窗内以竞争的方式确定接入非授权载波包括:根据收到的接入信息,判断是否存在与其他传输节点冲突,其中,接入信息为其他传输节点在第j次接入时发送的剩余k-j次接入对应的接入信息,k为在传输窗内的总接入次数,0<j<=k-1;在判断结果为是的情况下,依据传输节点的优先级接入非授权载波。
其中,第一系统对应的传输节点在传输窗内以竞争的方式接入非授权频谱是指:第一系统对应的传输节点在第j次接入时携带剩余k-j次接入对应的接入信息,第一系统对应的传输节点收到第一系统对应的其他传输节点的接入起始时刻后,如果和第一系统对应的传输节点的接入起始时刻相同,第一系统对应的传输节点根据优先级确定传输节点对应的接入起始时刻。
其中,第一系统对应的传输节点根据优先级确定传输节点对应的竞争接入起始时刻是指:优先级低的LTE传输节点的接入时刻向后延迟。
其中,在依据传输节点的优先级竞争在Nj时刻开始进行第j次接入非授权载波之前,还包括:依据以下因素至少之一,确定传输节点的优先级:传输节点的初次接入非授权载波的起始时刻;传输节点在前一次接入非授权载波的起始时刻;传输节点上业务的优先级。
其中,第一系统对应的传输节点在传输窗内接入次数小于等于最大接入次数是指:k的值大于K,停止接入,其中K为最大接入次数。
其中,第一系统对应的传输节点在传输窗内接入时间小于等于最大接入时间是指:累加每次接入的时间后的值大于T,停止接入,其中T为最大接入时间。

其中,当满足以下条件至少之一时,传输窗长度相对于前一个传输窗增加:在传输窗对应的检测窗内检测到非授权载波的占用比例大于第一预定阈值;在传输窗对应的检测窗内检测到非授权载波的利用率小于第二预定阈值;在传输窗对应的检测窗内检测到传输节点受到的干扰程度大于第三预定阈值;传输窗内的最大接入次数大于预定的最大接入次数的最大值;传输窗内的最大接入时间大于预定的最大接入时间的最大值。
当满足以下条件至少之一时,传输窗长度相对于前一个传输窗减少:在传输窗对应的检测窗内检测到非授权载波的占用比例小于第一预定阈值;在传输窗对应的检测窗内检测到非授权载波的利用率小于第二预定阈值;在传输窗对应的检测窗内检测到传输节点受到的干扰程度小于第三预定阈值;传输窗内的最大接入次数小于预定的最大接入次数的最小值;传输窗内的最大接入时间小于预定的最大接入时间的最小值。
当满足以下条件至少之一时,传输窗内的最大接入次数/最大接入时间相对于前一个传输窗内最大接入次数/最大接入时间增加:在传输窗对应的检测窗内检测到非授权载波的占用比例小于第一预定阈值;在传输窗对应的检测窗内检测到非授权载波的利用率小于第二预定阈值;在传输窗对应的检测窗内检测到传输节点受到的干扰程度小于第三预定阈值;传输窗长度达到预定的传输窗长度的最大值。

另外,在调整的传输窗长度大于预定的传输窗长度最大值的情况下,将传输窗长度确定为预定的传输窗长度最大值;在调整的传输窗长度小于预定的传输窗长度最小
值的情况下,将传输窗长度确定为预定的传输窗长度最小值;在调整的最大接入次数/最大接入时间大于预定的最大接入次数的最大值/预定的最大接入时间的最大值的情况下,将最大接入次数/最大接入时间确定为预定的最大接入次数的最大值/预定的最大接入时间的最大值;在调整的最大接入次数/最大接入时间小于预定的最大接入次数的最小值/预定的最大接入时间的最小值的情况下,将最大接入次数/最大接入时间确定为预定的最大接入次数的最小值/预定的最大接入时间的最小值。
即,如果调整后的最大接入次数/最大接入时间大于预定定义的最大接入次数/最大接入时间最大值,那么调整后的最大接入次数/最大接入时间等于预定定义的最大接入次数/最大接入时间最大值;如果调整后的最大接入次数/最大接入时间长度小于预定定义的最大接入次数/最大接入时间最小值,那么调整后的最大接入次数/最大接入时间长度等于预定定义的最大接入次数/最大接入时间最小值;如果调整后的传输窗长度大于预定义的传输窗最大值,那么调整后的传输窗长度等于预定义的传输窗最大值;如果调整后的传输窗长度小于预定义的传输窗最小值,那么调整后的传输窗长度等于预定义的传输窗最小值。
其中,上述检测窗可以为多种,例如,可以包括以下至少之一:传输窗的前一个传输窗、传输窗的前一个传输窗的部分、传输窗的前N个传输窗、预定时间长度的窗。需要说明的是,检测资源利用情况的检测窗和检测干扰情况的检测窗可以相同,也可以不同。

传输窗2对应的检测窗内检测到非授权频谱上资源利用率为50%,那么传输窗2对应的最大接入次数相对于传输窗1增加,优选的,传输窗2对应的最大接入次数为传输窗1的2倍,或者,
传输窗2对应的检测窗内检测到非授权频谱上资源利用率为50%且LTE传输节点受到的干扰小于X,那么传输窗2对应的最大接入次数相对于传输窗1增加,优选的,传输窗2对应的最大接入次数为传输窗1的2倍,或者,
传输窗2对应的检测窗内检测到非授权频谱上LTE系统占用时间达到40%且LTE传输节点受到干扰小于X,那么传输窗2对应的最大接入次数相对于传输窗1增加,优选的,传输窗2对应的最大接入次数为传输窗1的2倍,或者,

需要说明的是,如果调整后的最大接入次数大于Kmax,那么最大接入次数为Kmax。
优选实施方式三:
在本优选实施方式中,给出LTE传输节点以竞争的方式接入非授权频谱的具体实施例。
具体实施例一
图15是根据本发明实施例的给出一种LTE传输节点以竞争的方式接入非授权频谱的示意图一,如图15所示,假设LTE传输节点1接入次数k为1次,LTE传输节点2接入次数为为1次,检测窗得到的最大接入次数为3次。
LTE传输节点1在[0,Y]内生成1个随机数为N0-LTE1,LTE传输节点2在[0,Y]内生成1个随机数为N0-LTE2,本实施例中Y等于传输窗长度除以固定长度后向上取整,固定长度为大于10的正整数。
LTE传输节点1从N0-LTE1时刻开始检测非授权载波的状态,检测到CCA长度的空闲后,LTE传输节点1接入非授权频谱,开始发送数据,其中CCA的长度小于等于50us。
LTE传输节点2从N0-LTE2时刻开始检测非授权载波的状态,检测到CCA长度的空闲后,LTE传输节点2接入非授权频谱,开始发送数据,其中CCA的长度小于等于50us。
具体实施例二
图15是根据本发明实施例的一种LTE传输节点以竞争的方式接入非授权频谱的示意图一,如图15所示,假设LTE传输节点1接入时间为10ms,LTE传输节点2接入时间为10ms次,检测窗得到的最大接入时间为30ms。假设每次接入时的传输时间为10ms,那么传输节点1接入次数为1次,传输节点2接入次数为1次。
LTE传输节点1在[0,Y]内生成1个随机数为N0-LTE1,LTE传输节点2在[0,Y]内生成1个随机数为N0-LTE2,本实施例中Y等于传输窗长度除以固定长度后向上取整,固定长度为大于10的正整数。
LTE传输节点1从N0-LTE1时刻开始检测非授权载波的状态,检测到CCA长度的空闲后,LTE传输节点1接入非授权频谱,开始发送数据,其中CCA的长度大于20us,小于等于50us。
LTE传输节点2从N0-LTE2时刻开始检测非授权载波的状态,检测到CCA长度的空闲后,LTE传输节点2接入非授权频谱,开始发送数据,其中CCA的长度大于20us,小于等于50us。
具体实施例三
图16是根据本发明实施例的一种LTE传输节点以竞争的方式接入非授权频谱的示意图二,如图16所示,假设LTE传输节点1接入次数k为2次,LTE传输节点2接入次数为1次,检测窗得到的最大接入次数为3次。
LTE传输节点1在[0,Y]内生成2个随机数为N0-LTE1和N1-LTE1,LTE传输节点2在[0,Y]内生成1个随机数为N0-LTE2,其中N1-LTE1和N0-LTE2相等。
LTE传输节点1从N0-LTE1时刻开始检测非授权载波的状态,检测到CCA长度的空闲后,LTE传输节点1接入非授权频谱,开始发送数据,其中CCA的长度大于20us,小于等于50us;LTE传输节点1在接入时同时将携带第2次接入的接入起始时刻的信息N1-LTE1发送。
LTE传输节点2收到N1-LTE1,因为N1-LTE1和N0-LTE2相等且LTE-传输节点2的优先级低于LTE传输节点1,所以LTE传输节点2从N0-LTE2+1时刻开始检测非授权载波的状态,检测到CCA长度的空闲后,LTE传输节点2接入非授权频谱,开始发送数据,其中CCA的长度小于等于50us。
