Description

一种调度信令的配置方法、接收方法和相关设备
本申请要求于2016年3月25日提交中国专利局，申请号为201610178021.1、发明名称为“一种调度信令的配置方法、接收方法和相关设备”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
本发明涉及通信领域，尤其涉及一种非授权载波上调度信令的配置方法、接收方法和相关设备。
背景技术
随着通信业务量的急剧增加，3GPP（3rd Generation Partnership Project，第三代合作伙伴计划，简称3GPP）授权频谱显得越来越不足以提供更高的网络容量。为了进一步提高频谱资源的利用，3GPP正讨论如何在授权频谱的帮助下使用未授权频谱，如2.4GHz和5.8GHz频段。这些未授权频谱目前主要是WiFi（Wireless-Fidelity，无线保真，简称WiFi），蓝牙，雷达，医疗等系统在使用。一般来说，为已授权频段设计的接入技术，如LTE不适合在未授权频段上使用，因为LTE（Long Term Evolution，长期演进，简称LTE)这类接入技术对频谱效率和用户体验优化的要求非常高。然而，载波聚合功能让将LTE部署于非授权频段变为可能。3GPP提出了LAA（Licensed Assisted Access，授权频谱辅助接入，简称LAA）的概念，借助LTE授权频谱的帮助来使用未授权频谱。
LTE网络中由于有很好的正交性保证了干扰水平，所以基站与用户的上下行传输不用考虑周围是否有基站或用户在进行传输。如果LTE在非授权频段上使用时也不考虑周围是否有别的设备在使用非授权频段，那么将对WiFi设备带来极大的干扰。因为LTE只要有业务就进行传输，没有任何监听规则，那么WiFi设备在LTE有业务传输时就没法传输，只能等到LTE业务传输完成，才能检测到信道空闲状态，才能进行传输。
所以LTE在使用非授权频段时，最主要的关键点之一是确保LAA能够在公平友好的基础上和现有的接入技术（例如WiFi）共存。而传统的LTE系统中没有LBT（Listen Before Talk，先听后说，简称LBT）的机制来避免碰撞。为了与WiFi更好的共存，LTE需要一种LBT机制。这样，LTE在非授权频谱上如果检测到信道忙，则不能占用该频段，如果检测到信道闲，才能占用。现有技术还没有提供在非授权载波上进行上下行调度的方案，因此如何在非授权载波上进行上下行调度是目前研究的热点。
发明内容
本发明实施例所要解决的技术问题在于，提供一种非授权载波上调度信令的配置方法、接收方法、基站和用户设备。可提高调度的灵活性和通信系统的吞吐量。
为了解决上述技术问题，本发明实施例提供了一种非授权载波上调度信令的配置方法，包括：
基站配置非授权载波上被调度小区的载波调度配置消息；其中，所述载波调度配置消息包括：调度类型标识、调度小区标识和调度小区的物理下行共享信道PDSCH起始符号位置信息，所述调度类型标识表示半静态上下行自调度、半静态上下行跨载波调度或动态调度；
所述基站向用户设备发送携带所述载波调度配置消息的无线资源控制RRC信令。
相应地，本发明实施例还提供了一种非授权载波上调度信令的接收方法，包括：

所述用户设备根据所述载波调度配置消息监听调度小区和/或所述非授权载波上的小区的物理下行控制信道PDCCH中的用户设备特定UE Specific搜索空间。
相应的，本发明实施例还提供了一种非授权载波上调度信令的接收方法，包括：
用户设备接收基站携带非授权载波上被调度小区的载波调度配置消息和载波类型信息的无线资源控制RRC信令；其中，所述载波调度配置消息包括：调度类型标识、调度小区标识和调度小区的物理下行共享信道PDSCH起始符号位置信息，所述调度类型标识表示上下行自调度或上下行跨载波调度；
所述用户设备根据载波类型信息获取所述非授权载波上的小区的载波类型；
所述用户设备根据所述载波调度配置消息和所述载波类型监听所述调度小区和/或所述非授权载波上的小区的物理下行控制信道PDCCH中的用户设备特定UE Specific搜索空间。

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，所描述的实施例仅仅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。
参见图1，为本发明实施例提供的一种非授权载波上调度信令的配置方法的流程示意图，在本发明实施例中，所述方法包括：
S101、基站配置非授权载波上被调度小区的载波调度配置消息；其中，载波调度配置消息包括：调度类型标识、调度小区标识和调度小区的PDSCH起始符号位置信息，调度类型标识表示半静态上下行自调度、半静态上下行跨载波调度或动态调度。
具体的，载波调度配置消息用于表示调度非授权载波上小区的相关参数，该小区即当前的LAA Scell（Licensed Assisted Access Secondary Cell，授权频谱辅助接入的辅服务小区）；调度类型标识表示上行方向和下行方向的调度类型，调度类型标识表示的调度类型至少分为三种：半静态上下行自调度，半静态上下行跨载波调度和动态调度，半静态上下行自调度表示上行方向和下行方向均为半静态自调度即LAA SCell自己发送自己的资源调度信息，半静态上下行跨载波调度表示上行方向和下行方向均为半静态跨载波调度即由其他服务小区（例如授权载波上的主服务小区）来发送该LAA SCell的资源调度信息，动态调度表示上行方向和下行方向为动态调度，跨载波调度和自调度之间动态转换；调度小区标识表示执行调度的小区的身份，上行调度和下行调度均为同一个小区，调度小区的PDSCH起始符号位置信息表示执行调度的小区的PDSCH起始符号位置。如果是自调度，那么调度小区和被调度小区都是该非授权载波上的小区即LAA SCell；如果是跨载波调度，调度小区为别的服务小区比如授权载波上的主服务小区，被调度小区为该非授权载波上的小区即LAA SCell。
需要说明的是，对于调度类型也可以区分上行方向和下行方向，对于上行方向的调度类型和下行方向的调度类型采用两个不同的标识进行表示，从而进行区分上行方向和下行方向的调度类型。
S102、基站向用户设备发送携带载波调度配置消息的RRC信令。
具体的，基站通过授权载波向用户设备发送携带载波调度配置消息的RRC信令，用户设备根据载波调度配置消息的指示在指定的小区上进行上行调度或下行调度信令的接收。
可选的，所述调度类型标识为2个比特位。
具体的，调度类型标识为2个比特位，基站通过设置不同的值来表示不同的调度类型，例如：调度类型标识为cif-presence，cif-presence的值为01时，表示调度类型为半静态跨载波调度，cif-presence的值为00时，表示调度类型为半静态自调度，cif-presence的值为10表示调度类型为动态调度。
需要说明的是，2个比特位的值与调度类型的对应关系并不限于此，可以根据需要进行设置。
从上述实施例可以看出，基站根据非授权载波无法持续占用的特点，在配置调度信令时针对半静态调度和动态调度进行区分，这样基站能根据不同的分配方式灵活的调度传输资源，提高了通信系统的吞吐量。
参见图2，为本发明实施例提供的一种调度信令的接收方法的流程示意图，在本发明实施例中，所述方法包括：
S201、用户设备接收基站发送的携带非授权载波上被调度小区的载波调度配置消息的RRC信令；其中，载波调度配置消息包括调度类型标识、调度小区标识、调度小区的PDSCH起始符号位置信息。
具体的，用户设备接收基站发送的携带非授权载波上被调度小区的载波调度配置消息的RRC信令，解析得到载波调度配置消息中的相关参数，调度类型标识表示上行方向和下行方向的调度类型，调度类型标识表示至少三种调度类型：上下行半静态自调度、上下行半静态跨载波调度和动态调度，上下行半静态自调度表示上行方向和下行方向均为半静态上下行调度，半静态上下行跨载波调度表示上行方向和下行方向均为半静态跨载波调度，动态调度表示上行方向和下行方向为动态调度，跨载波调度和自调度之间动态转换；调度小区标识表示执行调度的小区的身份，上行调度和下行调度均为同一个小区，调度小区的PDSCH（Physical Downlink Shared Channel，物理下行共享信道，简称PDSCH）起始符号位置信息表示执行调度的小区的PDSCH起始符号位置。
S202、用户设备根据载波调度配置消息监听调度小区和/或所述非授权载波上的小区的PDCCH中的UE Specific搜索空间。
具体的，用户设备根据载波调度配置消息确定上下行调度类型，根据不同的调度类型监听调度小区和/或所述非授权载波上的小区的PDCCH（Physical Downlink Control Channel，物理下行控制信道，简称PDCCH）中的UE Specific搜索空间。
可选的，所述用户设备根据所述载波调度配置消息监听调度小区和/或所述非授权载波上的小区的PDCCH中的UE Specific搜索空间包括：
所述用户设备根据所述调度类型标识确定调度类型；
若所述调度类型标识表示半静态上下行自调度，所述用户设备监听当前非授权载波上的小区的PDCCH中的UE Specific搜索空间，获得上行调度信息和下行调度信息；该小区即当前的LAA SCell。
若所述调度类型标识表示半静态上下行跨载波调度，则根据所述调度小区标识和所述调度小区的PDSCH起始符号位置信息监听调度小区的PDCCH中的UE Specific搜索空间，获得上行调度信息和下行调度信息；
若所述调度类型标识表示动态调度，所述用户设备监听非授权载波上的小区即当前的LAA SCell和所述调度小区的PDCCH中的UE Specific搜索空间，获得上行调度信息和下行调度信息。
具体的，用户设备根据载波调度配置消息中的调度类型标识确定上下行调度类型，根据不同的调度类型监听调度小区和/或所述非授权载波上的小区的PDCCH中的UE Specific搜索空间；当用户设备确定调度类型为上下行半静态自调度，由于基站没有对调度小区标识和调度小区的PDSCH起始符号位置信息进行配置具体的值，用户设备直接监听非授权载波上的小区的PDCCH中的UE Specific搜索空间，获得上行调度信息和下行调度信息；当用户设备确定调度类型为上下行跨载波调度，由于基站对调度小区标识和调度小区的PDSCH起始符号位置信息配置了具体的值，用户设备根据调度小区标识和调度小区的PDSCH起始符号位置信息的指示监听调度小区的PDCCH中的UE Specific搜索空间，获得上行调度信息和下行调度信息；当用户设备确定调度类型为动态调度，则用户设备需要同时对当前的非授权载波上的小区和调度小区标识对应的小区进行监听，获得上行调度信息和下行调度信息。
参见图3，为本发明实施例提供的一种非授权载波上调度信令的接收方法的流程示意图，在本发明实施例中，所述方法包括：
S301、用户设备接收基站发送的携带非授权载波上被调度小区的载波调度配置消息和载波类型信息的RRC信令；其中，载波调度配置消息包括调度类型标识、调度小区标识和调度小区的PDSCH起始符号位置信息，调度类型标识表示上下行自调度或上下行跨载波调度。
具体的，载波调度配置消息用于表示调度非授权载波上的LAA SCell的相关参数，调度类型不区分上下行，调度类型标识表示上下行自调度或上下行跨载波调度，调度小区标识表示执行调度的小区的身份，调度小区的PDSCH起始符号位置信息表示执行调度的小区的PDSCH起始符号位置，载波类型信息表示被调度小区即当前非授权载波上的LAA SCell的载波类型，载波类型分为授权载波和非授权载波两种。
在一种可能的实施方式中，调度类型标识用1bit位来表示，例如，调度类型标识为cif-presence，当1bit位的值为1时，调度类型为上下行跨载波调度，当1bit位的值为0时，调度类型为上下行自调度。
S302、用户设备根据载波类型信息获取当前被调度小区的载波类型。
S303、用户设备根据载波调度配置消息和载波类型监听调度小区和/或所述非授权载波上的小区的PDCCH中的UE Specific搜索空间。

所述用户设备根据所述载波类型信息中携带的载频信息或载波类型指示符来确定所述被调度小区的载波类型为授权载波或非授权载波。
具体的，用户根据被调度小区的频点确定被调度小区（即该非授权频谱上的小区）的载波类型，或者根据载波类型指示符确定载波类型，例如，载波类型指示符的值为1表示载波类型为非授权载波，载波类型指示符的值为0表示载波类型为授权载波。
可选的，所述用户设备根据所述载波调度配置消息和所述载波类型监听调度小区和/或所述非授权载波上的小区的PDCCH中的UE Specific搜索空间包括：
若所述载波类型为授权载波，且所述调度类型标识表示上下行跨载波调度，用户设备确定调度类型为半静态上下行跨载波调度，监听调度小区的PDCCH中的UE Specific搜索空间，获得上行调度信息和下行调度信息；

具体的，用户设备根据被调度小区的载波类型，结合调度类型标识表示的调度类型重新确定实际的调度类型，若载波类型为授权载波，且调度类型标识表示上下行跨载波调度，用户设备确定调度类型为半静态上下行跨载波调度，监听调度小区的PDCCH中UE Specific搜索空间，获得上行调度信息和下行调度信息；若载波类型为非授权载波，且调度类型标识表示上下行跨载波调度，用户设备确定实际的调度类型为动态调度，用户设备需要同时监听非授权载波上的小区和调度小区中UE Specific搜索空间，获得上行调度信息和下行调度信息。
