  • LAA Long Term Evolution Advanced
  • a station should measure or perceive the channel before using an unlicensed carrier (ie, the "channel” here refers to the unlicensed carrier).
  • the process of sensing the channel is called Clear Channel Assessment (CCA). For example, suppose a station measures that the power of a channel on a 20 MHz bandwidth is not less than -60 dBm, then the station considers the channel to be busy; below -60 dBm it is idle.
  • CCA Clear Channel Assessment
  • the CCA station After the CCA station performs the CCA, it may find that the channel is busy, then the LAA station continues to perform CCA or waits; the LAA site may also find that the channel is idle, then the LAA station can start using the channel.

As shown in FIG. 1, the unlicensed carrier contends to the channel at the middle of the symbol 12 (i.e., the 13th symbol), and the channel can be used. At this time, however, neither the symbol boundary of the authorized carrier nor the sub-frame boundary of the authorized carrier is aligned.

Description

信道占用的方法及装置 技术领域
本发明涉及通信领域,具体而言,涉及一种信道占用的方法及装置。
背景技术
非授权载波(即免授权频谱)是指在满足政府部门(如国家无线电管理委员会)有关规定(无线电管制)下,不需要授权就能直接使用的频谱(或载波)。在我们的日常生活中,微波炉、遥控玩具飞机、无线鼠标、无线键盘、高保真无线上网(Wireless Fidelity简称为WiFi)、授权载波辅助接入的LTE(以下简称LAA)等都使用了非授权载波。
一个站点(或设备)在使用某个非授权载波之前,应先测量或感知一下信道(即,这里的“信道”就是指该非授权载波)。感知信道的过程称为空闲信道评估(Clear Channel Assessment,简称为CCA)。例如,假设一个站点测量到一个20MHz带宽上的信道的功率不低于-60dBm,则该站点认为信道是繁忙的;低于-60dBm则是空闲的。
LAA站点在执行CCA之后,可能会发现信道繁忙,则该LAA站点继续执行CCA或等待;LAA站点也可能会发现信道空闲,则该LAA站点可以开始使用该信道。
LAA站点可以开始使用该信道的时刻可能与辅助该信道(非授权载波)的授权载波在符号上和/或子帧上没有对齐,图1是相关技术中LAA站点竞争到非授权载波的示意图一,如附图1所示,非授权载波在符号12(即,第13个符号)的中间时刻就竞争到了信道,可以开始使用该信道了。但这时候既没对齐到授权载波的符号边界,也没对齐到授权载波的子帧边界。LAA站点可以开始使用该信道的时刻(即,成功竞争到了信道的时刻)到子帧边界的时间可能小于、等于或大于一个符号的时间。
由于LAA站点成功竞争到了信道的时刻没有对齐到符号上和/或子帧边界,这给LAA站点发射数据和对应的LAA终端接收数据带来了困难。如果等到子帧边界再开始发射,则该信道(非授权载波)可能会被别的LAA站点或WiFi站点抢走。如果立刻发射,则不知道需要发射什么内容、LAA终端不知道怎么接收、LAA站点不能跨载波调度该信道(非授权载波)的下行数据(从LAA站点到LAA终端)。
图2是相关技术中LAA站点竞争到非授权载波的示意图二,如图2所示,如果辅 助该信道(非授权载波)的授权载波的帧结构为时分双工(TDD)并且,LAA站点成功竞争到了信道的时刻为TDD的上行子帧、特殊子帧的上行部分、特殊子帧的保护间隔部分(GP),则LAA站点不能跨载波调度该信道(非授权载波)。这意味着该信道(非授权载波)可能会被别的LAA站点或WiFi站点抢走。如果一个站点不停地做CCA,则它会消耗一定的能源。非授权载波的获得(使用权)可能是通过竞争得到的。
图3是相关技术中LAA站点竞争到非授权载波的示意图三,如图3所示,如果一个LAA站点(如LAA-eNB 1)抢到了资源,周围的LAA站点(如LAA-eNB 2)不知道它要占用多长时间,从而可能需要不停地做CCA,进而增加了能源消耗。另外,如果周围的LAA站点(如LAA-eNB 2)不能直接听到该LAA站点的信号/能量,也会带来“隐藏站点”的问题。
针对相关技术中非授权载波会被抢走、占用时长以及存在“隐藏站点”的问题,目前尚未提出有效的解决方案。

下面结合附图和本发明可选实施例进行举例说明;
可选实施例一:
以LAA站点成功竞争到了信道(即非授权载波)的时刻离所述授权载波的下一个子帧边界的时间为M=1024个采样点、占用信号为单端口的小区特定的参考信号CRS、LAA站点在授权载波上发射物理下行控制信道PDCCH以指示对一个非授权载波的3毫秒占用信息为例来加以说明。图6是根据本发明可选实施例的LAA站点竞争到非授权载波后在其上发射占用信号的示意图,图7是根据本发明可选实施例的占用信号为单端口的CRS在一个PRB上的分布示意图。
如图3所示,LAA站点LAA-eNB 1成功竞争到了信道之后,LAA-eNB 1在该非授权载波上立即发射M=1024个采样点(如图6)的单端口的小区特定的参考信号CRS0(如图7)。
由于站点LAA-eNB 1在该非授权载波上存在能量(即发射了CRS0;如图7),周围的站点LAA-eNB 2接收上述单端口的小区特定的参考信号CRS0后可能能够感知到该能量的存在,从而能够感知到有别的站点已经占用了该非授权载波,从而不能再去占用该非授权载波。
站点LAA-eNB 1在下一个子帧(由符号0–13共14个符号组成,如图4)发射物理下行控制信道PDCCH。该PDCCH可以携带2比特的占用信息(这里为“10”)、符号起点信息(这里为“符号13”;第14个符号)和第一个符号的采样点起点信息(这里为“M=1024个采样点”)。
因此,站点LAA-eNB 1发射占用信号(CRS0;如图7)可有效地防止非授权载波会被抢走问题。周围的LAAUE接收该PDCCH可知道占用信息,从而可解决占用时长问题。周围的LAAUE把接收到的占用信息转发给服务自己的站点,从而可解决“隐藏站点”问题。
可选实施例二:
以LAA站点成功竞争到了信道(非授权载波)的时刻离所述授权载波的下一个子帧边界的时间为M=2000个采样点、占用信号为主同步信号PSS、占用信号(这里指 PSS)使用不同的序列以指示对一个非授权载波的2毫秒占用信息为例来加以说明。结合图3、图6、图8以及图9,其中,图8是根据本发明可选实施例的占用信号为PSS在整个系统带宽上的分布示意图一,图9是根据本发明可选实施例的占用信号为PSS在整个系统带宽上的分布示意图二。
如图3所示,LAA站点LAA-eNB 1成功竞争到了信道(非授权载波)之后,LAA-eNB 1在该非授权载波上立即发射M+K=2000+192=2192个采样点(如图6)的主同步信号PSS(如图8和图9),这里K=192。
由于需要发射的占用信号(主同步信号PSS)越过了子帧边界(也是符号边界),则LAA-eNB 1需要对下一个子帧的第一个符号的最前面(或最后面)K=192个采样点进行打孔。即,下一个子帧的第一个符号实际发射了2208-K=2016个采样点。
由于站点LAA-eNB 1在该非授权载波上存在能量(即,发射了PSS;如图8和如图9),周围的站点LAA-eNB 2(如图3)可能能够感知到该能量的存在,从而能够感知到有别的站点已经占用了该非授权载波,从而不能再去占用该非授权载波。
在如图8和如图9中,存在15个或16个PSS,如果这15个(或16个)PSS都发相同的序列,可定义为该LAA站点需要占用2ms时间;如果在中心子载波2边的7个(或8个)PSS各发射2个不同的序列,可定义为该LAA站点需要占用4ms时间。在本实施例中,LAA-eNB 1发射的15个(或16个)PSS都发相同的序列。
因此,站点LAA-eNB 1发射占用信号(PSS;如图8和图9)可有效地防止非授权载波会被抢走问题。周围的LAAUE接收该PSS可知道占用信息(需要占用2ms时间),从而可解决占用时长问题。周围的LAAUE把接收到的占用信息转发给服务自己的站点,从而可解决“隐藏站点”问题。
可选实施例三:
以LAA站点成功竞争到了信道(非授权载波)的时刻离所述授权载波的下一个子帧边界的时间为M=2192个采样点、占用信号为双端口的小区特定的参考信号CRS加上主同步信号PSS再加上辅同步信号SSS、占用信号(这里指CRS+PSS+SSS)使用不同的PSS序列以指示对一个非授权载波的2毫秒占用信息为例来加以说明。结合图3、图6、图10以及图11进行说明,其中,图10是根据本发明可选实施例的占用信号为PSS+SSS+CRS在整个系统带宽上的分布示意图一,图11是根据本发明可选实施例的占用信号为双端口的CRS在一个PRB上的分布示意图。
如图3所示,LAA站点LAA-eNB 1成功竞争到了信道(非授权载波)之后,LAA-eNB 1在该非授权载波上立即发射M=2192个采样点(如图6)的占用信号 CRS+PSS+SSS(如图10和图11)。
由于站点LAA-eNB 1在该非授权载波上存在能量(即,发射了CRS+PSS+SSS;如图10和图11),周围的站点LAA-eNB 2可能能够感知到该能量的存在,从而能够感知到有别的站点已经占用了该非授权载波,从而不能再去占用该非授权载波。
在图10中,有一个PSS,如果规定PSS发u=29的Zadoff-Chu序列,可定义为该LAA站点需要占用2ms时间;如果规定PSS发u=34的Zadoff-Chu序列,可定义为该LAA站点需要占用4ms时间。在本实施例中,LAA-eNB 1对PSS发射u=29的Zadoff-Chu序列。
因此,站点LAA-eNB 1发射占用信号(CRS+PSS+SSS;如图10和图11)可有效地防止非授权载波会被抢走问题。周围的LAAUE接收该PSS可知道占用信息(需要占用2ms时间),从而可解决占用时长问题。周围的LAAUE把接收到的占用信息转发给服务自己的站点,从而可解决“隐藏站点”问题。
可选实施例四:
以LAA站点工作在所述授权载波的双工方式为时分双工TDD并且所述LAA站点成功竞争到了所述非授权载波的时刻相对所述授权载波为TDD特殊子帧的下行导频时隙DwPTS的第二个符号、LAA站点在所述授权载波的TDD的上行子帧上发射增强的物理下行控制信道EPDCCH以指示对一个或多个非授权载波的占用信息和/或调度信息为例来加以说明。结合图3、图12以及图13进行详细的说明,其中图12是根据本发明可选实施例的LAA站点的授权载波为TDD双工方式、在一个特殊子帧S的中间时刻竞争到非授权载波的示意图,图13是根据本发明可选实施例的占用信号为双端口的CRS在一个PRB上分布的另一个示意图。
如图3所示,LAA站点LAA-eNB 1成功竞争到了信道(非授权载波)之后,LAA-eNB 1在该非授权载波上立即重复发射2192个采样点的双端口的小区特定的参考信号CRS(如图13)直到授权载波的TDD的上行子帧边界。
在授权载波的TDD的上行子帧上(U),LAA-eNB 1事先配置一些PRB用来发射增强的物理下行控制信道EPDCCH以指示对一个或多个非授权载波的占用信息和/或调度信息。在该授权载波的TDD的上行子帧上(U)没有受到调度的LAAUE需要接收上述EPDCCH。
由于站点LAA-eNB 1在该非授权载波上存在能量(即发射了CRS;如图13),周围的站点LAA-eNB 2可能能够感知到该能量的存在,从而能够感知到有别的站点已经 占用了该非授权载波,从而不能再去占用该非授权载波。
然后,站点LAA-eNB 1在下一个上行子帧U(由符号0–13共14个符号组成;如图12)上发射增强的物理下行控制信道EPDCCH。该EPDCCH可以携带2比特的占用信息(这里为“10”)、符号起点信息(这里为“S子帧的第二个符号”;第14个符号)和第一个符号的采样点起点信息。站点LAA-eNB 1在下一个上行子帧U也可发射另一条或多条EPDCCH以调度LAAUE。
因此,站点LAA-eNB 1发射占用信号(CRS;如图13)可有效地防止非授权载波会被抢走问题。周围的LAAUE接收一条或多条EPDCCH可知道占用信息和/或调度信息,从而可解决占用时长问题。周围的LAAUE把接收到的占用信息转发给服务自己的站点,从而可解决“隐藏站点”问题。
可选实施例五:
以LAA站点工作在所述授权载波的双工方式为时分双工TDD并且所述LAA站点成功竞争到了所述非授权载波的时刻相对所述授权载波为TDD特殊子帧的上行导频时隙UpPTS的第一个符号、LAA站点在所述授权载波的TDD的上行子帧上发射增强的物理下行控制信道EPDCCH以指示对一个或多个非授权载波的占用信息和/或调度信息为例来加以说明。结合图3、图12以及图14进行详细说明,其中,图14是根据本发明可选实施例的占用信号为随机接入前导Preamble在整个系统带宽上的分布示意图。
如图3所示,LAA站点LAA-eNB 1成功竞争到了信道(非授权载波)之后,LAA-eNB 1在该非授权载波上立即重复发射2192个采样点的随机接入前导Preamble(如图14)直到授权载波的TDD的上行子帧边界。
如图14所示,每个随机接入前导Preamble占6个物理资源块PRB。包括该带宽的中心的随机接入前导Preamble在内,总共有15个随机接入前导Preamble。每个随机接入前导Preamble可使用相同(或不同)的随机接入前导序列。不同的随机接入前导序列的组合可以表示占用时间长度信息。例如,使用相同的随机接入前导序列表示占用4毫秒的时间。
在授权载波的TDD的上行子帧上(U),LAA-eNB 1事先配置一些PRB用来发射增强的物理下行控制信道EPDCCH以指示对一个或多个非授权载波的占用信息和/或调度信息。在该授权载波的TDD的上行子帧上(U)没有受到调度的LAAUE需要接收上述EPDCCH。
由于站点LAA-eNB 1在该非授权载波上存在能量(即,发射了CRS;附图12), 周围的站点LAA-eNB 2可能能够感知到该能量的存在,从而能够感知到有别的站点已经占用了该非授权载波,从而不能再去占用该非授权载波。
然后,站点LAA-eNB 1在下一个上行子帧U(如图12)上发射增强的物理下行控制信道EPDCCH。该EPDCCH可以携带2比特的占用信息(这里为“10”)、符号起点信息(这里为“S子帧的第二个符号”;第14个符号)和第一个符号的采样点起点信息。站点LAA-eNB 1在下一个上行子帧U也可发射另一条或多条EPDCCH以调度LAAUE。
因此,站点LAA-eNB 1发射占用信号(随机接入前导;如图14)可有效地防止非授权载波会被抢走问题。周围的LAAUE接收一条或多条EPDCCH可知道占用信息和/或调度信息,从而可解决占用时长问题。周围的LAAUE把接收到的占用信息转发给服务自己的站点,从而可解决“隐藏站点”问题。
另外,站点LAA-eNB 1也可在特殊子帧S上发射物理下行控制信道PDCCH和/或增强的物理下行控制信道EPDCCH以通知LAAUE它正准备去竞争非授权载波(此时尚未竞争),要求LAAUE做好接收准备。
可选实施例六:
以LAA站点工作在所述授权载波的双工方式为时分双工TDD并且所述LAA站点成功竞争到了所述非授权载波的时刻相对所述授权载波为TDD的上行子帧的第2个符号、LAA站点在所述授权载波的TDD的上行子帧结束后紧接着的下行子帧上发射物理下行控制信道PDCCH和/或增强的物理下行控制信道EPDCCH以指示对一个或多个非授权载波的占用信息和/或调度信息为例来加以说明。结合图2和图3进行详细说明。
如图3所示,LAA站点LAA-eNB 1成功竞争到了信道(非授权载波)之后,LAA-eNB 1在该非授权载波上立即给LAAUE发射物理下行共享信道PDSCH。发射PDSCH时,结束的时间点需要对齐到子帧边界。对应该PDSCH的物理下行控制信道PDCCH和/或增强的物理下行控制信道EPDCCH则在授权载波的TDD的上行子帧结束后紧接着的下行子帧上发射。
由于站点LAA-eNB 1在该非授权载波上存在能量(即发射了PDSCH;如图2),周围的站点LAA-eNB 2(附图3)可能能够感知到该能量的存在,从而能够感知到有别的站点已经占用了该非授权载波,从而不能再去占用该非授权载波。
然后站点LAA-eNB 1在授权载波的TDD的上行子帧结束后紧接着的下行子帧D(如图2)上发射物理下行控制信道PDCCH和/或增强的物理下行控制信道EPDCCH。 该PDCCH和/或EPDCCH可以携带2比特的占用信息(这里为“10”)、符号起点信息(这里为“U子帧的第二个符号”)和第一个符号的采样点起点信息。
因此站点LAA-eNB 1发射信道(PDSCH)可有效地防止非授权载波会被抢走问题。周围的LAAUE接收一条或多条PDCCH和/或EPDCCH可知道占用信息和/或调度信息,从而可解决占用时长问题。周围的LAAUE把接收到的占用信息转发给服务自己的站点,从而可解决“隐藏站点”问题。

以LAA站点工作在所述授权载波的双工方式为时分双工TDD并且所述LAA站点成功竞争到了所述非授权载波的时刻相对所述授权载波为TDD特殊子帧的上行导频时隙UpPTS的第一个符号、LAA站点在所述授权载波的TDD的上行子帧上发射增强的物理下行控制信道EPDCCH以指示对一个或多个非授权载波的占用信息和/或调度信息为例来加以说明。结合如图3、图12和图14进行详细的说明。
如图3所示,LAA站点LAA-eNB 1成功竞争到了信道(非授权载波)之后,LAA-eNB 1在该非授权载波上以单载波频分多址SC-FDMA方式立即重复发射2192个采样点的随机接入前导Preamble(如图14)直到授权载波的TDD的上行子帧边界。
如图14所示,每个随机接入前导Preamble以单载波频分多址SC-FDMA方式占6个物理资源块PRB。包括该带宽的中心的随机接入前导Preamble在内,总共有15个随机接入前导Preamble。每个随机接入前导Preamble可使用相同(或不同)的随机接入前导序列。不同的随机接入前导序列的组合可以表示占用时间长度信息。例如,使用相同的随机接入前导序列表示占用4毫秒的时间。
在授权载波的TDD的上行子帧上(U),LAA-eNB 1事先配置一些PRB用来发射增强的物理下行控制信道EPDCCH以指示对一个或多个非授权载波的占用信息和/或调度信息。在该授权载波的TDD的上行子帧上(U)没有受到调度的LAAUE需要接收上述EPDCCH。
由于站点LAA-eNB 1在该非授权载波上存在能量(即发射了CRS;如图14),周围的站点LAA-eNB 2可能能够感知到该能量的存在,从而能够感知到有别的站点已经占用了该非授权载波,从而不能再去占用该非授权载波。
然后站点LAA-eNB 1在下一个上行子帧U(如图12)上发射增强的物理下行控制信道EPDCCH。该EPDCCH可以携带2比特的占用信息(这里为“10”)、符号起点信息(这里为“S子帧的第二个符号”;第14个符号)和第一个符号的采样点起点信息。站点LAA-eNB 1在下一个上行子帧U也可发射另一条或多条EPDCCH以调度 LAAUE。
因此,站点LAA-eNB 1发射占用信号(随机接入前导;如图14)可有效地防止非授权载波会被抢走问题。周围的LAAUE接收一条或多条EPDCCH可知道占用信息和/或调度信息,从而可解决占用时长问题。周围的LAAUE把接收到的占用信息转发给服务自己的站点,从而可解决“隐藏站点”问题。
另外,站点LAA-eNB 1也可在特殊子帧S上发射物理下行控制信道PDCCH和/或增强的物理下行控制信道EPDCCH以通知LAAUE它正准备去竞争非授权载波(此时尚未竞争),要求LAAUE做好接收准备。
另外,站点LAA-eNB 1也可指定一个或多个LAAUE以单载波频分多址SC-FDMA方式在该非授权载波上发射一个或多个上述随机接入前导Preamble,上述每个随机接入前导Preamble占各不相同的6个物理资源块PRB。
可选实施例八:
下面以LAA站点工作在所述授权载波的双工方式为时分双工TDD并且所述LAA站点成功竞争到了所述非授权载波的时刻相对所述授权载波为TDD特殊子帧的下行导频时隙DwPTS的第二个符号、LAA站点在所述授权载波的TDD的上行子帧上发射增强的物理下行控制信道EPDCCH以指示对一个或多个非授权载波的占用信息和/或调度信息为例来加以说明、LAA站点在所述授权载波的TDD的下行导频时隙DwPTS的第3个符号上在所述授权载波发射占用信号(如,用PSS)。结合图3、图12和图13进行详细说明。
如图3所示,LAA站点LAA-eNB 1成功竞争到了信道(非授权载波)之后,LAA-eNB 1在该非授权载波上立即重复发射2192个采样点的双端口的小区特定的参考信号CRS(附图11)直到授权载波的TDD的上行子帧边界。另外,LAA站点LAA-eNB1在所述授权载波的TDD的下行导频时隙DwPTS的第3个符号上在所述授权载波发射占用信号(如,用PSS)。
在授权载波的TDD的上行子帧上(U),LAA-eNB 1事先配置一些PRB用来发射增强的物理下行控制信道EPDCCH以指示对一个或多个非授权载波的占用信息和/或调度信息。在该授权载波的TDD的上行子帧上(U)没有受到调度的LAAUE需要接收上述EPDCCH。
由于站点LAA-eNB 1在该非授权载波上存在能量(即发射了CRS;如图13),周围的站点LAA-eNB 2可能能够感知到该能量的存在,从而能够感知到有别的站点已经占用了该非授权载波,从而不能再去占用该非授权载波。
另外,又由于LAA站点LAA-eNB 1在所述授权载波的TDD的下行导频时隙DwPTS的第3个符号上在所述授权载波发射占用信号(如,用PSS),周围的LAAUE能够感知到占用信号(如,PSS)的存在,从而认为该LAA站点LAA-eNB 1已获得了一个或多个非授权载波的使用权。周围的LAAUE也可把这一信息报告给服务自己的LAA站点,从而让周围的LAA站点知道已有LAA站点使用了一个或多个非授权载波。
之后,站点LAA-eNB 1在下一个上行子帧U(由符号0–13共14个符号组成;如图10)上发射增强的物理下行控制信道EPDCCH。该EPDCCH可以携带2比特的占用信息(这里为“10”)、符号起点信息(这里为“S子帧的第二个符号”;第14个符号)和第一个符号的采样点起点信息。
站点LAA-eNB 1在下一个上行子帧U也可发射另一条或多条EPDCCH以调度LAAUE。
因此,站点LAA-eNB 1发射占用信号(CRS;附图11)可有效地防止非授权载波会被抢走问题。周围的LAAUE接收一条或多条EPDCCH可知道占用信息和/或调度信息,从而可解决占用时长问题。周围的LAAUE把接收到的占用信息转发给服务自己的站点,从而可解决“隐藏站点”问题。

如图3所示,LAA站点LAA-eNB 1成功竞争到了信道(非授权载波)之后,LAA-eNB 1在该非授权载波上立即重复发射2192个采样点的随机接入前导Preamble(附图12)直到授权载波的TDD的上行子帧边界。
如图14所示,每个随机接入前导Preamble占6个物理资源块PRB。包括该带宽的中心的随机接入前导Preamble在内,总共有15个随机接入前导Preamble。每个随机接入前导Preamble可使用相同(或不同)的随机接入前导序列。不同的随机接入前导序列的组合可以表示占用时间长度信息。例如,使用相同的随机接入前导序列表示占用4毫秒的时间。
另外,上述随机接入前导Preamble也可以5MHz为单位来重复发射。例如,每个 20MHz带宽上有4个5MHz的随机接入前导Preamble的发射。每个5MHz上有3个随机接入前导Preamble发射,每个随机接入前导Preamble占6个连续的且各不相同的物理资源块PRB。每个5MHz中心上有一个随机接入前导Preamble发射。
上述随机接入前导Preamble可以用下面的伪随机序列(PN码)来产生。

其中,D为伪随机序列的长度,如,D=139或D=839。
其中,c(n)=(x1(n+NC)+x2(n+NC))mod2
其中,NC=1600,n=0,1,2,3,...,F-1,F=(2^L)-1,L为产生该序列的移存器的级数(如,取L=10)。
其中,

x2(n+31)=(x2(n+3)+x2(n+2)+x2(n+1)+x2(n))mod2为长度31的Gold序列。
其中,第一个序列(x1)使用x1(0)=1,x1(n)=0,n=1,2,...,30来初始化。
其中,第2个序列(x2)使用

或者
Figure PCTCN2015092334-appb-000003
或者cinit=nSI来初始化。其中,SI为所要携带的信息比特(如,占用时间长度信息),k为该信息比特数量(如,4比特的占用时间长度信息);所述可以是新的小区标识ID(大于503),也可以是已有的小区标识ID(0~503)。
在授权载波的TDD的上行子帧上(U),LAA-eNB 1事先配置一些PRB用来发射增强的物理下行控制信道EPDCCH以指示对一个或多个非授权载波的占用信息和/或调度信息。在该授权载波的TDD的上行子帧上(U)没有受到调度的LAAUE需要接收上述EPDCCH。
由于站点LAA-eNB 1在该非授权载波上存在能量(即发射了CRS;如图14),周围的站点LAA-eNB 2可能能够感知到该能量的存在,从而能够感知到有别的站点已经占用了该非授权载波,从而不能再去占用该非授权载波。
然后,站点LAA-eNB 1在下一个上行子帧U(如图12)上发射增强的物理下行 控制信道EPDCCH。该EPDCCH可以携带2比特的占用信息(这里为“10”)、符号起点信息(这里为“S子帧的第二个符号”;第14个符号)和第一个符号的采样点起点信息。站点LAA-eNB 1在下一个上行子帧U也可发射另一条或多条EPDCCH以调度LAAUE。
因此,站点LAA-eNB 1发射占用信号(随机接入前导;如图14)可有效地防止非授权载波会被抢走问题。周围的LAAUE接收一条或多条EPDCCH可知道占用信息和/或调度信息,从而可解决占用时长问题。周围的LAAUE把接收到的占用信息转发给服务自己的站点,从而可解决“隐藏站点”问题。
另外,站点LAA-eNB 1也可在特殊子帧S上发射物理下行控制信道PDCCH和/或增强的物理下行控制信道EPDCCH以通知LAAUE它正准备去竞争非授权载波(此时尚未竞争),要求LAAUE做好接收准备。
可选实施例十:
以LAA站点成功竞争到了信道(非授权载波)的时刻离所述授权载波的下一个子帧边界的时间为M=2192*2=4384个采样点、占用信号为双端口的小区特定的参考信号CRS加上主同步信号PSS再加上辅同步信号SSS、占用信号(这里指CRS+PSS+SSS)使用不同的PSS序列以指示对一个非授权载波的2毫秒占用信息为例来加以说明。结合图3、图6、图11以及图15进行说明,其中,图15是根据本发明可选实施例的占用信号为PSS+SSS+CRS在整个系统带宽上的分布示意图二(最前面的2192个采样点为SSS+CRS;最后面的2192个采样点为PSS+CRS;PSS和SSS都是在整个带宽的中心的6个PRB上)。
如图3所示,LAA站点LAA-eNB 1成功竞争到了信道(非授权载波)之后,LAA-eNB 1在该非授权载波上立即发射M=2192*2=4384个采样点(如图6)的占用信号CRS+PSS+SSS(如图11和图15)。
由于站点LAA-eNB 1在该非授权载波上存在能量(即发射了CRS+PSS+SSS;如图11和图15),周围的站点LAA-eNB 2可能能够感知到该能量的存在,从而能够感知到有别的站点已经占用了该非授权载波,从而不能再去占用该非授权载波。
在图15中有一个PSS,如果规定PSS发u=29的Zadoff-Chu序列,可定义为该LAA站点需要占用2ms时间;如果规定PSS发u=34的Zadoff-Chu序列,可定义为该LAA站点需要占用4ms时间。在本实施例中,LAA-eNB 1对PSS发射u=29的Zadoff-Chu序列。
因此,站点LAA-eNB 1发射占用信号(CRS+PSS+SSS;如图11和图15)可有效地防止非授权载波会被抢走问题。周围的LAAUE接收该PSS可知道占用信息(需要占用2ms时间),从而可解决占用时长问题。周围的LAAUE把接收到的占用信息转发给服务自己的站点,从而可解决“隐藏站点”问题。
