  • the preemption resource of the WiFi system on the unlicensed spectrum is as follows: first, the channel is monitored, and when the channel idle time reaches the distributed inter-frame space (DIFS), the current channel is determined to be an idle channel. The stations of each channel waiting to access then enter a random backoff phase to prevent multiple sites from colliding on the same resources. In addition, in order to ensure fairness, it is also stipulated that each site cannot occupy spectrum resources for a long time. When a certain time or data transmission limit is reached, resources need to be released for other devices/systems to seize resources.

Description

一种数据信道调度方法、装置及系统
本申请要求在2014年11月6日提交中国专利局、申请号为201410637906.4、发明名称为“一种数据信道调度方法、装置及系统”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本发明涉及无线通信技术领域，尤其涉及一种数据信道调度方法、装置及系统。
背景技术
随着移动数据业务量的不断增长，频谱资源越来越紧张，仅使用授权频谱资源进行网络部署和业务传输可能已经不能满足业务量需求，因此长期演进(Long Term Evolution,LTE)系统可以考虑在非授权频谱资源上部署传输(Unlicensed LTE，简称为U-LTE或者LTE-U)，以提高用户体验和扩展覆盖。
非授权频谱没有规划具体的应用系统，可以为多种无线通信系统如蓝牙、WiFi等共享，多种系统间通过抢占资源的方式使用共享的非授权频谱资源。举例说明，WiFi系统在非授权频谱上的抢占资源方式如下：首先对信道进行监听，当信道空闲时间达到分布式帧间间隙(Distributed Inter-Frame Space，DIFS)，便判断当前信道为空闲信道，然后各个等待接入的信道的站点，便进入一个随机回退阶段，用于避免多个站点在相同的资源发生碰撞。此外，为了保证公平性，还规定每个站点不能长期占用频谱资源，到达一定时间或数据传输量上限时，需要释放资源，以供其他设备/系统抢占资源。
LTE在非授权频段的载波上工作时，为了保证与其他设备或系统公平共享频谱资源，LTE基站与用户设备(User Equipment，UE)也需要竞争资源。
LTE系统如何在非授权频谱上工作还没有明确方法。一种达成共识的方法是采用载波聚合(CA)机制利用非授权频段的载波上的频谱资源，即非授权频段的载波作为CA机制中辅载波(Scell)用于数据传输。
按照现有协议对CA机制的规定，将无法满足上述非授权频段的载波应用于CA时的需求。

具体实施方式
下面将结合附图，对本发明实施例提供的技术方案进行详细说明。
在下面的说明过程中，先从基站侧和UE侧的配合实施进行说明，再分别从基站侧与UE侧的实施进行说明，但这并不意味着二者必须配合实施，实际上，当基站侧与UE侧分开实施时，也解决了分别在基站侧、UE侧所存在的问题，只是二者结合使用时，会获得更好的技术效果。
本发明实施例提供的基站和UE配合实施的数据信道调度方法，其流程如图1所示，具体包括如下操作：
步骤100、基站为UE配置服务小区集合，该服务小区集合包括至少一个服务小区；
本发明实施例中，为UE配置服务小区集合，具体包括：为UE分配服务小区集合，并将该服务小区集合的配置信息发送给UE。
优选的，服务小区集合由激活的服务小区构成。
步骤110、UE接收基站对服务小区集合的配置。
接收基站对服务小区集合的配置，即接收基站发送的服务小区集合的配置信息。
步骤120、上述基站为上述UE配置上述服务小区集合中的每个服务小区对应的第一服务小区，第一服务小区为该服务小区集合中的服务小区；
本发明实施例中，为UE配置服务小区集合中的每个服务小区对应的第一服务小区，具体包括：为UE分配服务小区集合中的每个服务小区对应的第一服务小区，并将分配的第一服务小区的配置信息发送给UE。
步骤130、上述UE接收上述基站对上述服务小区集合中的每个服务小区对应的第一服务小区的配置；
接收基站对服务小区集合中的每个服务小区对应的第一服务小区的配置，具体是指，接收基站发送的第一服务小区的配置信息。
步骤140、上述基站为上述UE分配上述服务小区集合中的每个服务小区对应的第二服务小区，第二服务小区为该服务小区集合中的服务小区；
本发明实施例中，为UE配置服务小区集合中的每个服务小区对应的第二服务小区，具体包括：为UE分配服务小区集合中的每个服务小区对应的第二服务小区，并将分配的第二服务小区的配置信息发送给UE。
步骤150、上述UE接收上述基站对上述服务小区集合中的每个服务小区对应的第二服务小区的配置；
接收基站对服务小区集合中的每个服务小区对应的第二服务小区的配置，具体是指，接收基站发送的第二服务小区的配置信息。
步骤160、上述基站在第三服务小区对应的第一服务小区上向该UE发送第一PDCCH，该第一PDCCH中携带用于调度该第三服务小区与该UE进行下行数据传输的下行调度信息；
本发明实施中，第一服务小区为调度其对应的服务小区与UE进行下行数据传输的服务小区，其发送的携带该下行调度信息的PDCCH称为第一PDCCH。
步骤170、上述UE在上述第一服务小区上接收上述第一PDCCH。
步骤180、上述基站在上述第三服务小区对应的第二服务小区上向该UE发送第二PDCCH，该第二PDCCH中携带用于调度该第三服务小区与该UE进行上行数据传输的上行调度信息；
本发明实施例中，第二服务小区为调度其对应的服务小区与UE进行上行数据传输的的服务小区，其发送的携带该上行调度信息的PDCCH称为第二PDCCH。
本发明实施例中，第三服务小区为该服务小区集合中与上述UE进行上行数据传输和下行数据传输的服务小区。
步骤190、上述UE在上述第二服务小区上接收上述第二PDCCH。
本发明实施例中，服务小区可以工作在授权频段的载波上，也可以工作在非授权频段的载波上。
本发明实施例中，服务小区集合中的同一个服务小区对应的第一服务小区和第二服务小区可以是相同的服务小区，也可以是不同的服务小区。
本发明实施例中，服务小区集合中的各个服务小区对应的第一服务小区可以是该服务小区自身，也可以是该服务小区自身之外的服务小区。
如果第一服务小区为其对应的服务小区自身，优选的，该第一服务小区工作在非授权频段。
如果第一服务小区为其对应的服务小区自身之外的服务小区，该第一服务小区可以工作在授权频段。
本发明实施例中，服务小区集合中的各个服务小区对应的第二服务小区可以为该服务小区自身之外的服务小区，也可以为该服务小区自身。
如果第二服务小区为其对应的服务小区自身之外的服务小区，优选的，该第二服务小区工作在授权频段。
如果第二服务小区为其对应的服务小区自身，该第二服务小区可以工作在非授权频 段。
应当指出的是，本发明实施例中，可以对服务小区集合进行重配置。
每次配置完服务小区集合后，配置第一服务小区和配置第二服务小区的集合的时机根据实际场景、运营商需求等等确定，本发明不作限定。另外，可以对第一服务小区进行重配置，也可以对第二服务小区进行重配置。且为同一个服务小区配置第一服务小区和配置第二服务小区是独立的，这两个配置之间没有时序关系。
还应当指出的是，步骤160和步骤180之间没有时序关系。在需要进行下行调度时，执行步骤160，在需要进行上行调度时，执行步骤180。
本发明实施例提供的方法，分别独立对UE的第三服务小区进行下行数据调度的第一服务小区与对该第三服务小区进行下行数据调度的第二服务小区进行配置，能够满足非授权频段的载波应用于CA时的需求。
这是因为，发明人在实现本发明的过程中，发现现有协议对CA机制的规定是，在配置用于数据传输的服务小区与用于传输调度信息的服务小区的关联关系时，对用于数据传输的服务小区进行下行调度和上行调度的调度信息只能通过同一个服务小区发送，具体如图2所示。图2所针对的场景为：UE有三个服务小区，这三个服务小区分别工作在载波1、载波2和载波3上。这三个服务小区中，用于发送PDSCH和接收PUSCH的服务小区(PDSCH/PUSCH服务小区，即本发明实施例中的第三服务小区)只能由这三个服务小区中的一个服务小区进行调度(即PDCCH服务小区)。而本发明实施例提供的方案，分别独立对UE的第三服务小区进行下行数据调度的第一服务小区与对该第三服务小区进行上行数据调度的第二服务小区进行配置。仍以上述三个服务小区为例，如图3所示，对PDSCH/PUSCH服务小区进行上行调度和进行下行调度的PDCCH服务小区可以不为同一个服务小区。由于在非授权频段的载波上传输PDSCH时，如果基站刚刚竞争得到非授权频段的第一个子帧，由于来不及与授权频段的载波交互或者该第一个子帧不一定是完整的数据子帧，下行调度信息在授权频段的载波上传输存在困难，因此优选的在非授权频段的载波上传输下行调度信息，而在非授权频段的载波上传输PUSCH时，如果也在非授权频段的载波上传输上行调度信息，基站需要竞争资源，如果竞争到该资源，该资源可能仅用于传输上行调度信息，导致资源浪费，如果竞争不到资源，会导致上行调度的机会受限，因此优选的在授权频段传输上行调度信息。按照现有的CA机制规定，无法实现上述调度需求。而采用本发明实施例提供的方案，则可以在授权频段的载波传输上行调度信息，在非授权频段的载波传输下行调度信息。
本发明实施例提供的方案，适用于服务小区集合中所有工作在非授权频段的载波上的服务小区采用全下行(DL only)模式，也适用于服务小区集合中所有工作在非授权频段的载波上的服务小区采用下行(DL)+上行(UL)的传输模式。
本发明实施例提供的方案，适用于服务小区集合中所有工作在非授权频段的载波上的服务小区采用时分复用(TDD)模式，也适用于服务小区集合中所有工作在非授权频段的载波上的服务小区采用频分复用(FDD)模式。
本发明实施例提供的基站侧的数据信道调度方法，如图4所示，具体包括如下操作：
步骤400、为UE配置服务小区集合，该服务小区集合包括至少一个服务小区。
步骤410、为该UE配置该服务小区集合中的每个服务小区对应的第一服务小区，第一服务小区为该服务小区集合中的服务小区。
步骤420、为该UE配置该服务小区集合中的每个服务小区对应的第二服务小区，第二服务小区为该服务小区集合中的服务小区。
步骤430、在第三服务小区对应的第一服务小区上向该UE发送第一PDCCH，该第一PDCCH中携带用于调度上述第三服务小区与该UE进行下行数据传输的下行调度信息。
步骤440、在上述第三服务小区对应的第二服务小区上向该UE发送第二PDCCH，该第二PDCCH中携带用于调度该第三服务小区与该UE进行上行数据传输的上行调度信息，该第三服务小区为该服务小区集合中与该UE进行上行数据传输和下行数据传输的服务小区。
基站侧实施例中，对于第一服务小区、第二服务小区等的描述可以参照上述实施例，重复之处不再赘述。
基于上述任意实施例，较佳地，可以通过无线资源控制协议(RRC)信令，为上述UE配置服务小区集合。
基于上述任意实施例，较佳地，可以通过RRC信令，为UE配置服务小区集合中的每个服务小区对应的第一服务小区。
基于上述任意实施例，较佳地，可以通过RRC信令，为UE配置服务小区集合中的每个服务小区对应的第二服务小区。
下面举例说明基站侧对UE的服务小区的配置。
当基站为UE配置的服务小区集合全部工作在授权频段上的载波时，为服务小区集合中的每个服务小区配置的第一服务小区与第二服务小区为相同的服务小区，具体配置方式可以参照3GPP版本R10的协议规定。
当基站为UE配置的服务小区集合中，既有工作在授权频段的载波上的服务小区，也有工作在非授权频段的载波上的服务小区，基站为服务小区集合中工作在授权频段的载波上的每个服务小区配置的第一服务小区和第二服务小区为相同的服务小区，具体配置方式可以参照3GPP版本R10的协议规定；基站为服务小区集合中工作在非授权频段的载波上的每个服务小区分别配置第一服务小区和第二服务小区，较优地，为工作在非授权频段的载波上的服务小区配置的第一服务小区工作在非授权频段上，为工作在授权频段的载波上 的服务小区配置的第二服务小区工作在授权频段上，例如，第二服务小区为Pcell。
以图3所示为例，其中载波1为授权频段的载波，载波2和载波3为非授权频段的载波。工作在载波1上的服务小区对应的第一服务小区和第二服务小区均为该服务小区自身；工作在载波2和载波3上的服务小区对应的第二服务小区均为工作在载波1上的服务小区；工作在载波2上的服务小区对应的第一服务小区为工作在载波1上的服务小区；考虑到工作在载波1上的服务小区的PDCCH容量可能受限，基站将工作在载波3上的服务小区对应的第一服务小区配置为该服务小区自身。
如果基站对非授权频段的载波上传输的PUSCH的调度PDCCH仅在授权载波上承载，这就不需要为发送PUSCH的调度PDCCH而去专门竞争下行信道资源，同时也不会因为在非授权频段上的信道竞争失败而影响非授权频段的载波上传输的PUSCH调度。对于非授权频段的载波上传输的PDSCH的调度PDCCH传输可综合考虑调度效率以及授权频段的载波上的容量等因素进行确定。例如，若授权频段的载波上的PDCCH容量充足，则可以将非授权的载波上传输的PDSCH的调度PDCCH配置于授权频段的载波上传输，否则在非授权频段的载波上传输。综上，采用本发明实施例提供的方法可有效提升非授权频段的载波的调度效率。
