Description

一种非授权载波中资源的管理方法和装置 技术领域
本申请涉及但不限于通信领域。
背景技术
在LTE(Long Term Evolution，长期演进)的演进过程中，在2014年9月份，LTE Rel-13版本开始立项研究，其中Rel-13中一个重要的立项就是LTE系统使用非授权载波工作。这项技术将使得LTE系统能够使用目前存在的非授权载波，大大提升LTE系统的潜在频谱资源，使得LTE系统能够获得更低的频谱成本。
另外，对于非授权频谱，也是存在很多优势的：
1.免费/低费用(不需要购买非频谱，频谱资源为零成本)。
2.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)。
3.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)。
4.无线接入技术多(跨不同的通信标准，协作难，网络拓扑多样)。
5.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)。
6.应用多(从资料看，多业务被提及可以在其中运营，例如Machine to machine(M2M)、Vehicle to vehicle(V2V))。
但是，LTE系统使用非授权载波面临着众多的问题，部分如下：
对于非授权频谱，会有多个系统工作在相同的频谱上，如WIFI系统。为了保证每个系统公平使用非授权频谱，LTE系统有可能在时间上不连续地占用非授权频谱，所以为了实现LTE系统部署在非授权频谱时的数据传输，如何确定非授权频谱上载波对应的HARQ(Hybrid Auto Repeat Request，混合自动重传请求)重传、ACK/NACK反馈或者CSI(Channel State Information， 信道状信息态)反馈或PHICH(Physical Hybrid ARQ Indicator Channel，物理混合自动重传指示信道)传输等以及实现数据传输是亟待解决的问题。

本发明的实施方式
下面将结合附图对本发明的实施方式进行描述。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。
在本发明实施例中，站点1抢占到非授权载波使用权，确定占用非授权载波的资源，其中占用资源分为2种类型，第一类型为站点1使用的资源，第二类型为站点1优先使用的资源，站点1在第一类型资源使用结束后，能够优先使用第二类型资源发送和/或接收数据。
图1为本发明实施例提供的非授权载波中资源的管理方法流程示意图。图1所示方法包括：
步骤101、站点获取非授权载波的使用权；
步骤102、所述站点确定所述非授权载波中所述站点占用的资源的使用策略；
步骤103、所述站点根据所述使用策略使用占用的资源进行数据的发送和/或接收操作。
本发明提供的实施例，在获取到非授权载波的使用权后，设置该非授权载波的使用策略，方便日后使用该资源传输信息，达到有效利用传输资源进行数据传输的目的。
在本发明实施例中，在占用非授权载波资源后，不但直接使用该载波的部分资源，还设置优先使用其中一部分资源的信息，方便日后使用该资源传输信息，达到有效利用传输资源进行数据传输的目的，解决和缓解非授权载波中由于占用非授权载波时长有限，导致部分控制相关的数据不能及时发送的问题，从而提升了非授权载波中的传输效率。
图2为本发明实施例提供中站点占用非授权载波的资源的示意图1。图2所示示意图中，站点1占用第一类型资源后，站点1将占用的情况通知下属UE(用户设备)，或者占用时长信息通知给下属接收端。
当然，占用时长信息也是可以不需要通知的。参见图3所示，图3为本发明实施例提供中站点占用非授权载波的资源的示意图2，图3所示的示意图中通过标准协议固化每一次占用非授权载波的时长都是固定的，例如基于固定帧结构的来占用非授权载波时。这样其他站点都可以根据协议获知占用的第一类型资源的时长。
在时间顺序上，所述站点配置第一类型资源位于第二类型资源之前。
站点使用第一类型资源传输结束后，如果站点仍然需要传输，则站点接着再使用第二类型资源进行传输；如果站点不需要再传输，站点不再使用所述第二类型资源。
当站点1不使用第二类型资源发送或不从第二类型资源接收其他站点给它发送的数据时，站点1则在第二类型资源到来时，不发送数据，或者站点1通知其他站点不使用第二类型资源发送数据。其过程为：站点1通过干净信道评估(Clear Channel Assessment，CCA，本发明实施例中也可以包括Extended CCA(eCCA)，下同)来判断非授权载波是否空闲，当空闲时，站点1占用非授权载波，并确定自己占用的第一类型资源和第二类型资源。第一类型资源为站点1在CCA结束之后连续占用的非授权载波的使用时间(可以以子帧为单位度量)。例如占用4个子帧(描述可以包括CCA所在的子帧，也可以不包括，但是要事先约定。LTE的一个子帧为1ms)。第二类型资源与第一类型资源在时间上是非连续的(连续的情况，可以认为属于第一类型资源)，其中与第一类型资源的间隔(以第一类型最后一个子帧n计算间隔)建议如下：间隔为1ms(或n+2)、2ms(或n+3)、3ms(或n+4)、4ms(或n+5)、5ms(或n+6)、6ms(或n+7)、7ms(或n+8)、8ms(或n+9)、16ms(或n+17)、1.5ms、2.5ms中的一个或多个。其中，间隔信息可以通过标准协议固化，且可以根据第二类型资源的不同用途固化不同的间隔，这样就可以省去信令通知邻近站点和接收端。如果不采用标准协议固化，那么间隔信息需要通知，可以通过广播类型的信息发送。也可以和占用时长信息同时发送(如果需要)。
其中，CCA是用来评估载波/信道是否空闲的，实现的方法很多，常见的就是从非授权载波中接收一个固定时长的信号，然后检测该信号的能量是 否超过一门限，如果超过门限则为忙，载波不可用，否则为空，载波可用。也包括扩展的CCA，其目的也是通过多个能量检测，来判断载波是否空闲，如果多个检测都为空闲，则可用，否则不可用。CCA也有避免多个站点同时竞争到非授权载波的作用。例如不同的站点执行的CCA的数量不同。
第二类型资源也是可以按照如下方式：第二类型资源为非连续的多个子帧，例如，当第二类型资源为3个子帧时，可以与第一类型资源最后一个子帧的间隔为：4ms、8ms、16ms。
所述第二类型资源的计量单位为1ms或一个子帧，或0.5ms，或对于标准循环前缀时由1至7个OFDM符号组成，或者对于长循环前缀时由1至6个OFDM符号组成。所述第二类型资源由非连续的多个计量单位的资源组成。
第二类型资源能被用于下面目的或用途：用于接收端发送NACK/ACK、用于站点1重传数据或信号、用于站点1发送PHICH数据、用于站点1发送上行/下行授权信息、用于接收端端发送授权信息、用于发送参考信号。多个目的的信息或数据或信号能被同时发送在第二类型资源中。如果第二类型资源同时支持上行和下行时，第二类型资源的子帧(或时隙(0.5ms时长的资源))能够包含下行资源和上行资源，可选的，上下行资源之间可以有保护间隔。或者上行和下行在第二类型资源不同的子帧中的发送。所述第二类型资源同时支持上行、下行，且只包含一个计量单位时，第二类型资源包含下行资源、上行资源和保护间隔，其中，保护间隔为可选的。
几种第二类型资源的使用方式：
方式1，站点1(可以是基站或UE)在抢占到非授权载波资源后，获得第一类型非授权载波资源，同时默认站点1也是获得第二类型非授权载波资源的优先使用权。当第二类型资源到来时，站点1在第二类型资源到来时不需要执行CCA过程，直接在第二类型资源中发送数据。例如站点1发送PHICH数据、授权信息。
方式2，站点1(可以是基站或UE)在抢占到非授权载波资源后，获得第一类型非授权载波资源，同时默认站点1也是获得第二类型非授权载波资 源的优先使用权。当第二类型资源到来时，站点1在第二类型资源到来时不需要执行CCA过程，直接在第二类型资源中接收数据。例如站点1在第二类型接收约定站点发送的数据。例如接收端发送的NACK/ACK信息。
方式3，站点1(可以是基站或UE)在抢占到非授权载波资源后，获得第一类型非授权载波资源，同时默认站点1也是获得第二类型非授权载波资源的优先使用权。当第二类型资源到来时，站点1指定的接收端发送数据时，在第二类型资源到来时不需要执行CCA过程，直接在第二类型资源中发送数据。
方式4，站点1(可以是基站或UE)在抢占到非授权载波资源后，获得第一类型非授权载波资源，同时默认站点1也是获得第二类型非授权载波资源的优先使用权。站点1在第二类型资源中不执行CCA，直接发送再接收数据。例如站点1在第二类型资源中先发送数据再接收数据。例如站点1在一个子帧中前部分先发送信号，再剩余资源中接收接收端发送的NACK/ACK信息。也可以在所述前部分发送的授权信息。这里按照先发送再接收的原则，可以避免邻近站点抢占第二类型资源，例如接收端由于发送功率小有可能使得邻近站点侦听到第二类型资源空闲，邻近站点从而抢占使用第二类型资源。
所述站点利用所述第二类型资源时在第二类型资源中按照时分复用方式同时执行发送和接收。
所述站点1在第二类型资源中直接发送再接收数据包括：站点1在第二类型资源前部分资源中发送信号，再从后续资源中接收约定接收端发送的信息。其中，前部分资源与后续资源按照OFDM符号在第二类型资源中划分获得。前部分资源占用前1至2或3或4个OFDM符号，后续资源占用剩余全部OFDM符号，或者后续资源与前部分资源之间留有间隙。间隙可以为小于等于2个OFDM符号，例如20us。
站点在使用第二类型资源之前执行的CCA的抢占概率(统计概率)高于站点获取第一类型资源时执行的CCA的抢占概率。其中此种情况是针对配置中要求每个站点都进行CCA检测的前提下使用的，通过设置该站点的抢占概率高，保证该站点能够得到第二类型资源。
在第二类型资源到来时，第一种方法，站点1直接使用之，不需要执行CCA过程。或第二种方法，在第二类型资源到来时，站点1执行一个CCA过程，但是该CCA过程具有比抢占第一类型资源的CCA更短的时间，这样站点1与其他站点比较能够优先抢占到第二类型资源，这种方式可以避免影响其他系统(例如wifi)正在使用第二类型资源，如果采用这种方式有可能造成第二类型资源不存在。所以针对不同的实际场景，可以选择不同的方式。
当然为了简化设计，可以事先约定第二类型资源的配置情况，例如约定第二类型资源的间隔、数量、单位时长等信息。这些约定可以根据第二类型资源不同的用途，确定适合各自的配置。下面会给出不同用途的第二类型资源的最优配置。对于利用第二类型资源发送上行数据的情况，最优的间隔可以是1ms，但是这对于接收端硬件的处理速度要求比较高，这种设计有利于非授权载波提升效率。其次间隔可以是2ms、3ms，其中3ms的设计可以兼容LTE中的设计需求。对于利用第二类型资源发送下行数据，间隔为4ms、5ms、6ms、7ms、8ms或16ms，这样有利于兼容LTE中的设计需求。
对于站点1的第二类型资源，其他站点想要使用时，可以按照下述方案执行：
方式1，其他站点在第二类型资源的每一个子帧中，需要先执行CCA过程，如果CCA检测的结果为空闲，则该子帧中剩余的资源可以使用。
方式2，其他站点在第二类型资源的第一个子帧中先执行CCA过程，如果CCA检测的结果为空闲，则该子帧中剩余的资源以及第二类型资源中的其他子帧均可以使用。
下面以实施例进行说明。
实施例1
图4为本发明实施例提供的占用非授权载波资源的示意图3。图4所示示意图中，系统确定的第二部资源的分布情况如下：与第一类型资源结束子帧间隔为5ms(即第一类型资源的最后一个子帧为n，则第二类型资源的第一个子帧为n+6，这里可以根据系统中最低硬件处理时延来确定，如果处理时 延比较大，可以选择n+7或更大，反之也可以)，第二类型资源由1个子帧组成。
站点1通过CCA过程，获得非授权载波的使用权，确定需要占用的第一类型资源的占用时长，并将占用时长信息发送给接收端。站点1同时根据上述假设确定第二类型的资源的位置。站点1在第一类型资源中发送或接收数据，在站点1第一类型资源使用结束时，获知在第一类型资源中发送的数据存在需要重传的部分，则站点1就可以在第二类型资源到来时，将需要重传的数据进行发送。接收端接收站点1发送的占用时长信息，并根据上述假设确定第二类型资源的位置，当接收端在第一类型资源中接收的数据反馈了NACK时，接收端可以在第二类型资源中接收站点1的重传数据。此时在第一类型资源中任何子帧的重传数据都可以在第二类型资源中重传。
假设站点1第一类型资源为4个子帧，分别记为n-3、n-2、n-1、n，第二类型资源的第一个子帧为n+6。站点1在第n-1个子帧中为接收端1发送数据，接收端1未能正确接收，反馈了NACK(在授权载波中传输)；站点1在第n-2子帧中为接收端2发送数据，接收端2未能正确接收，反馈了NACK(该NACK也是在授权载波中反馈的，并且按照LTE的原则那么实际上反馈是在n+2子帧上的)，站点1是可以在n+6之前接收到的上述2个反馈信息，这样站点1能够在第二类型资源n+6中发送重传数据给接收端1和接收端2。
对于第一类型资源中反馈了NACK的接收端，需要在第二类型资源中接收站点1的重传数据，如果需要重传的数据比较多，第二类型资源不够重传全部数据，那么站点1可以选择部分重传，其他部分不重传。
在第二类型资源到来时，站点1直接使用之，不需要执行CCA过程。
其他站点接收站点1发送的占用时长信息，根据约定获知第二类型资源的位置，当第二类型资源到来时，如果其他站点想要使用第二类型资源，那么其他站点需要在第二类型资源的第一个子帧中先执行CCA过程，如果CCA检测的结果为空闲，则该子帧中剩余的资源以及第二类型资源中的其他子帧均可以使用；或者如果在第二类型资源的每一个子帧中先执行CCA过程，当检测结果为空闲，则对应的子帧剩余的资源可以为其他站点使用。
如果其他站点不计划使用第二类型资源，则在第二类型资源到来时暂停 发送。
实施例2
图5为本发明实施例提供中站点占用非授权载波的资源的示意图4。图5所示示意图中，系统确定的第二类型资源的分布情况如下：与第一类型资源结束子帧间隔为4ms(即第一类型资源的最后一个子帧为n，则第二类型资源的第一个子帧为n+5，这里可以根据系统中最低硬件处理时延来确定，如果处理时延比较大，可以选择n+6或更大，反之也可以)，第二类型资源由1个子帧组成。
站点1通过CCA过程，获得非授权载波的使用权，确定需要占用的第一类型资源的占用时长，并将占用时长信息发送给接收端。站点1同时根据上述假设确定第二类型的资源的位置。站点1在第一类型资源中调度接收端发送上行数据，或者站点1下属UE获知所属站点1获得的第一类型资源后，UE自主调度发送上行数据给站点1。站点1从第一资源中接收UE发送的数据，并判断是否正确接收，形成对应的PHICH信息，如果不能在第一类型资源中发送，则站点1在第二类型资源中发送对应的PHICH信息。此时在第一类型资源中任何子帧的接收数据对应的PHICH都可以在第二类型资源中发送。接收端接收站点1发送的占用时长信息，并根据上述假设确定第二类型资源的位置，当接收端在第一类型资源中发送数据给站点1，未收到站点1发送PHICH信息时，接收端可以在第二类型资源中接收站点1发送的PHICH信息。
假设站点1第一类型资源为4个子帧，分别记为n-3、n-2、n-1、n，第二类型资源的第一个子帧为n+5。站点1在第n-1个子帧中接收接收端1发送的数据，并正确接收；站点1在第n-2子帧中接收接收端2发送的数据，未正确接收。一种情况，如果按照相关技术的LTE的调度和定时关系，站点1在n子帧上发送上行授权信息，那么接收端3在子帧n+4上发送上行数据(在授权载波中发送)，站点1在n+4上接收到接收端3发送的数据，那么站点1在n+8时才会反馈PHICH，如果考虑到这种定时关系时，可以假设第二类型资源在n+8上。但是考虑非授权载波时，接收端存在可能自主发送数据的情况，本实施例中，站点1需要能够在n+5上反馈PHICH信息。该PHICH 信息可以包括第一类型资源中任意子帧的PHICH信息。
对于第一类型资源中未接收到PHICH信息的接收端，需要在第二类型资源中接收站点1发送的PHICH信息。
在第二类型资源到来时，站点1直接使用之，不需要执行CCA过程。
其他站点接收站点1发送的占用时长信息，根据约定获知第二类型资源的位置，当第二类型资源到来时，如果其他站点想要使用第二类型资源，那么其他站点需要在第二类型资源的第一个子帧中先执行CCA过程，如果CCA检测的结果为空闲，则该子帧中剩余的资源以及第二类型资源中的其他子帧均可以使用；或者如果在第二类型资源的每一个子帧中先执行CCA过程，当检测结果为空闲，则对应的子帧剩余的资源可以为其他站点使用。
如果其他站点不计划使用第二类型资源，则在第二类型资源到来时暂停发送。
实施例3
假设系统确定的第二部资源的分布情况如下：与第一类型资源结束子帧间隔为3ms(即第一类型资源的最后一个子帧为n，则第二类型资源的第一个子帧为n+4)，第二类型资源由1个子帧组成。
站点1通过CCA过程，获得非授权载波的使用权，确定需要占用的第一类型资源的占用时长，并将占用时长信息发送给接收端。站点1同时根据上述假设确定第二类型的资源的位置。站点1在第一类型资源中发送或接收数据，在站点1第一类型资源使用结束时，获知在第一类型资源中发送的数据对应NACK/ACK未接收到(由接收端发送)，则站点1就可以在第二类型资源到来时，从第二类型资源中接收上述NACK/ACK信息。当然，接收端需要接收站点1发送的占用时长信息，并根据上述假设确定第二类型资源的位置。在第一类型资源结束时接收端还未在第一类型资源中发送NACK/ACK时，接收端就可以在第二类型资源中发送该NACK/ACK。此时接收端能够发送第一类型资源中任何子帧对应的NACK/ACK在第二类型资源中重传。
假设站点1第一类型资源为4个子帧，分别记为n-3、n-2、n-1、n，第二类型资源的第一个子帧为n+4。站点1在第n-1个子帧中为接收端1发送数 据，接收端1未能正确接收；站点1在第n-2子帧中为接收端2发送数据，接收端2正确接收，按照LTE的NACK/ACK反馈定时，接收端1和接收端2在第一类型资源结束时，均不能发送NACK/ACK，那么接收端1和接收端2就在第二类型资源中发送NACK/ACK。
在第二类型资源到来时，接收端1和接收端2直接使用之，不需要执行CCA过程。
其他站点接收站点1发送的占用时长信息，根据约定获知第二类型资源的位置，当第二类型资源到来时，如果其他站点想要使用第二类型资源，那么其他站点需要在第二类型资源的第一个子帧中先执行CCA过程，如果CCA检测的结果为空闲，则该子帧中剩余的资源以及第二类型资源中的其他子帧均可以使用；或者如果在第二类型资源的每一个子帧中先执行CCA过程，当检测结果为空闲，则对应的子帧剩余的资源可以为其他站点使用。
如果其他站点不计划使用第二类型资源，则在第二类型资源到来时暂停发送。
本实施例中，选择第二类型资源为n+4，是为了兼容LTE系统的定时，但是对于非授权载波，在一些地区或国家存在管制法规，为了符合管制法规，第二类型资源可以设计在n+2或n+3，这样更容易满足管制法规的需求，但是对于硬件的处理速度要求较高。所以本实施例中根据实际的地区/国家，可以选择第二类型资源为n+2或n+3。
实施例4
由于接收端的发送功率一般比较小，当发送数据时容易被邻近站点侦听不到，从而邻近站点得出非授权载波为空闲，然后抢占使用，下面提供一个实施例，使得基站帮助接收端稳固第二类型资源的使用权。参考图2。
假设系统确定的第二部资源的分布情况如下：与第一类型资源结束子帧间隔为3ms(即第一类型资源的最后一个子帧为n，则第二类型资源的第一个子帧为n+4)，第二类型资源由1个子帧组成。
站点1通过CCA过程，获得非授权载波的使用权，确定需要占用的第一类型资源的占用时长，并将占用时长信息发送给接收端。站点1同时根据上 述假设确定第二类型的资源的位置。站点1在第一类型资源中发送或接收数据，在站点1的第一类型资源使用结束时，获知在第一类型资源中发送的数据对应NACK/ACK未接收到(由接收端发送)，则站点1就可以在第二类型资源到来时，从第二类型资源中接收上述NACK/ACK信息。当然，接收端需要接收站点1发送的占用时长信息，并根据上述假设确定第二类型资源的位置。在第一类型资源结束时接收端还未在第一类型资源中发送NACK/ACK时，接收端就可以在第二类型资源中发送该NACK/ACK。此时接收端能够发送第一类型资源中任何子帧对应的NACK/ACK在第二类型资源中重传。
假设站点1第一类型资源为4个子帧，分别记为n-3、n-2、n-1、n，第二类型资源的第一个子帧为n+4。站点1在第n-1个子帧中为接收端1发送数据，接收端1未能正确接收；站点1在第n-2子帧中为接收端2发送数据，接收端2正确接收，按照LTE的NACK/ACK反馈定时，接收端1和接收端2在第一类型资源结束时，均不能发送NACK/ACK，那么接收端1和接收端2就在第二类型资源中发送NACK/ACK。
在第二类型资源到来时，站点1在第二类型资源中的前部分发送信号(参考信号或占用信道的信号)，剩余部分停止发送。接收端1和接收端2直接使用所述剩余部分发送所述NACK/ACK，不需要执行CCA过程。其中前部分可以是子帧中前几个OFDM符号，剩余部分可以是子帧中其他的OFDM符号。可选的前几个OFDM符号为第一个OFDM符号。这样其他站点在第二类型资源开始时就会检测到非授权载波为忙，从而不再占用非授权载波，从而保证第二类型资源为接收端发送使用。
其他站点接收站点1发送的占用时长信息，根据约定获知第二类型资源的位置，当第二类型资源到来时，如果其他站点想要使用第二类型资源，那么其他站点需要在第二类型资源的第一个子帧中先执行CCA过程，如果CCA检测的结果为空闲，则该子帧中剩余的资源以及第二类型资源中的其他子帧均可以使用；或者如果在第二类型资源的每一个子帧中先执行CCA过程，当检测结果为空闲，则对应的子帧剩余的资源可以为其他站点使用。
如果其他站点不计划使用第二类型资源，则在第二类型资源到来时暂停 发送。
本实施例中，选择第二类型资源为n+4，是为了兼容LTE系统的定时，但是对于非授权载波，在一些地区或国家存在管制法规，为了符合管制法规，第二类型资源可以设计在n+2或n+3，这样更容易满足管制法规的需求，但是对于硬件的处理速度要求较高。所以本实施例中根据实际的地区/国家，可以选择第二类型资源为n+2或n+3。
实施例5
在实施例4的基础上，在第二类型资源的前部分，站点1也可以发送授权信息或PHICH信息。这种方式比较适合第一类型资源中既有下行又有上行的情况。
假设系统确定的第二部资源的分布情况如下：与第一类型资源结束子帧间隔为3ms(即第一类型资源的最后一个子帧为n，则第二类型资源的第一个子帧为n+4)，第二类型资源由1个子帧组成。
假设站点1第一类型资源为10个子帧，分别记为n-9、n-8…n-1、n，第二类型资源的第一个子帧为n+4。假设站点1在第n-1个子帧中为接收端1发送数据，接收端1未能正确接收；站点1在第n-2子帧中为接收端2发送数据，接收端2正确接收，按照LTE的NACK/ACK反馈定时，接收端1和接收端2在第一类型资源结束时，均不能发送NACK/ACK，那么接收端1和接收端2就在第二类型资源中发送NACK/ACK。又假设站点1在n子帧中正确接收到接收端发送数据，在第一类型资源结束时，站点1没有发送对应的PHICH。此时站点1可以在第二类型资源中发送该PHICH。
在第二类型资源到来时，站点1在第二类型资源中的前部分发送PHICH(也可以还有其他信号)，剩余部分停止发送。接收端1和接收端2直接使用所述剩余部分发送所述NACK/ACK，且都不需要执行CCA过程。
其他站点接收站点1发送的占用时长信息，根据约定获知第二类型资源的位置，当第二类型资源到来时，如果其他站点想要使用第二类型资源，那么其他站点需要在第二类型资源的第一个子帧中先执行CCA过程，如果CCA检测的结果为空闲，则该子帧中剩余的资源以及第二类型资源中的其他 子帧均可以使用；或者如果在第二类型资源的每一个子帧中先执行CCA过程，当检测结果为空闲，则对应的子帧剩余的资源可以为其他站点使用。
如果其他站点不计划使用第二类型资源，则在第二类型资源到来时暂停发送。
本实施例中，选择第二类型资源为n+4，是为了兼容LTE系统的定时，但是对于非授权载波，在一些地区或国家存在管制法规，为了符合管制法规，第二类型资源可以设计在n+2或n+3，这样更容易满足管制法规的需求，但是对于硬件的处理速度要求较高。所以本实施例中根据实际的地区/国家，可以选择第二类型资源为n+2或n+3。
实施例6
本实施例描述第二类型资源的释放。
站点1通过CCA获得第一类型资源的使用权后，并同时获得了第二类型资源的优先使用权，当站点1不需要使用第二类型资源时，站点1通过在第二类型资源到来时，站点1或站点1指示的接收端不在第二类型资源中发送任何信号。这样其他站点在第二类型资源到来时先通过CCA检测，如果发现第二类型资源空闲，则使用之。站点1也可以通过发送信令通知其他站点释放第二类型资源。可以采用广播类型的信令。
实施例7
站点1能够利用第二类型资源发送测量相关的信号，这些信号能被UE用于相关的测量。此时第二类型资源与第一类型资源的间隔为1ms、2ms最佳。
