Description

消息发送/接收装置、方法以及通信系统 技术领域
本发明涉及通信领域，特别涉及一种消息发送/接收装置、方法以及通信系统。
背景技术
随着社会的不断发展和进步，通信业务需求的持续增长为未来无线通信系统提出了挑战。为了支持快速增长的业务量和日益繁多的新业务，全球各研究机构及标准化组织先后启动了第五代(5G)无线通信系统研究。
例如，“车联网”已经吸引了大量研究机构和标准化组织的关注。第三代伙伴项目(3GPP，3rd Generation Partnership Project)定义了车联网的三种场景：车辆与车辆(V2V，vehicle-to-vehicle)通信，车辆与行人(V2P，Vehicle-to-Pedestrian)通信以及车辆与网络(V2I/N，Vehicle-to-Infrastructure/Network)通信，可以统称为V2X通信。
再例如，如下应用场景被涉及：机器类通信(MTC，Machine Type Communication)、增强的移动宽带(eMBB，enhanced Mobile Broadband)和超可靠低时延通信(uRLLC，ultra-Reliable Low Latency Communication)，等等。
另一方面，用户设备(UE，User Equipment)是无线通信系统中的重要组成部分，是直接为用户提供各类通信服务的载体。用户设备已经不仅仅局限在手机等面向人的终端类型，传感器、机器、机器人等面向物联网(IoT，Internet of Things)的用户设备将大规模应用。由于用户设备的体积有限，随着业务类型的多样化以及用户需求的不断提高，用户设备面临的复杂度和功耗问题将更加严峻。
应该注意，上面对技术背景的介绍只是为了方便对本发明的技术方案进行清楚、完整的说明，并方便本领域技术人员的理解而阐述的。不能仅仅因为这些方案在本发明的背景技术部分进行了阐述而认为上述技术方案为本领域技术人员所公知。
发明内容
发明人发现：未来无线通信系统需要进一步考虑在满足用户大量多样性业务需求的同时尽量降低用户设备的功耗。而在例如V2P、MTC等通信中，大量消息(例如 广播/多播消息)的发送和接收将导致用户设备频繁地监听和接收消息，从而导致过高的功耗。
本发明实施例提供一种消息发送/接收装置、方法以及通信系统。通过消息类型所对应的标识对消息的控制信息进行加解扰，降低用户设备的功耗。
根据本发明实施例的第一个方面，提供一种消息发送方法，包括：
确定待发送给一个或多个用户设备的某一消息的消息类型；
采用所述消息类型所对应的标识对所述消息的控制信息进行加扰；其中不同的标识对应不同的消息类型；
向所述一个或多个用户设备发送所述消息的数据信息以及加扰后的控制信息。
根据本发明实施例的第二个方面，提供一种消息发送装置，包括：
类型确定单元，其确定待发送给一个或多个用户设备的某一消息的消息类型；
信息加扰单元，其采用所述消息类型所对应的标识对所述消息的控制信息进行加扰；其中不同的标识对应不同的消息类型；
消息发送单元，其向所述一个或多个用户设备发送所述消息的数据信息以及加扰后的控制信息。
根据本发明实施例的第三个方面，提供一种消息接收方法，包括：
采用消息类型所对应的标识对接收到的控制信息进行解扰；其中不同的标识对应不同的消息类型；
在成功解扰所述控制信息的情况下接收所述控制信息所关联的数据信息。
根据本发明实施例的第四个方面，提供一种消息接收装置，包括：
信息解扰单元，其采用消息类型所对应的标识对接收到的控制信息进行解扰；其中不同的标识对应不同的消息类型；
消息接收单元，其在成功解扰所述控制信息的情况下接收所述控制信息所关联数据信息。
根据本发明实施例的第五个方面，提供一种通信系统，所述通信系统包括：

用户设备，其包括如上所述的消息接收装置。
本发明实施例的有益效果在于：网络设备通过消息类型所对应的标识对消息的控制信息进行加扰，用户设备通过消息类型所对应的标识对控制信息进行解扰，在控制 信息解扰成功的情况下才继续接收所述消息(即数据信息)；由此用户设备可以对不偏好的消息不继续处理，能够降低用户设备的功耗。

在本申请中，网络设备例如可以是基站，基站可以被称为接入点、广播发射机、节点B、演进节点B(eNB)等，并且可以包括它们的一些或所有功能。在文中将使用术语“基站”，每个基站对特定的地理区域提供通信覆盖。
在本申请中，移动站或设备可以被称为“用户设备”(UE)。UE可以是固定的或移动的，并且也可以称为移动台、终端、接入终端、用户单元、站等。UE可以是蜂窝电话、个人数字助理(PDA)、无线调制解调器、无线通信设备、手持设备、膝上型计算机、无绳电话、汽车等。
下面结合附图对本发明实施例进行说明。
实施例1
本发明实施例提供一种消息发送方法，从网络设备(例如基站)一侧进行说明。
图1是本发明实施例的消息发送方法的示意图，如图1所示，消息发送方法包括：
步骤101，网络设备确定待发送给一个或多个用户设备的某一消息的消息类型；
步骤102，网络设备采用该消息类型所对应的标识对该消息的控制信息进行加扰；其中不同的标识对应不同的消息类型；
步骤103，网络设备向所述一个或多个用户设备发送该消息的数据信息以及加扰后的控制信息。
在本实施例中，用户设备例如可以是IoT系统的MTC终端，或者是车联网系统的V2P终端，但本发明不限于此，例如该用户设备还可以是其他网络系统的终端。本发明实施例可以适用于任何进行消息发送/接收的系统。
在本实施例中，该网络设备可以为该用户设备所属小区的基站；该基站可以为宏基站(例如eNB)，用户设备由该宏基站产生的宏小区(例如Macro cell)提供服务；本发明实施例的基站也可以为微基站，用户设备由该微基站产生的微小区(例如Pico cell或者micro cell)提供服务。但本发明实施例不限于此，可以根据实际的需要确定具体的场景。
此外，该网络设备例如也可以是路边设备(RSU，Road Side Unit)等集中控制设备或装置，以下仅以网络设备是基站为例进行说明。
在本实施例中，消息类型可以包括：周期性广播消息、事件触发消息等，也可以包括消息业务类型，或者还可以是某一类型设备发送的消息等；但本发明不限于此，可以根据实际情况定义具体的消息类型。此外，标识(例如本发明中可称为group-ID)可以是根据无线网络临时标识(RNTI，Radio Network Temporary Identity)的生成规则而获得的标识，也可以是随机生成的标识，本发明不限于此，可以采用现有任意的标识生成方法。
在本实施例中，不同的标识对应不同的消息类型。消息类型与标识的对应关系可以预先被配置，或者根据用户设备上报的辅助信息而被配置。通过消息类型所对应的标识对消息进行加扰，可以使得用户设备仅对偏好的消息进行处理。
表1示出了不同的标识对应不同的消息类型的例子。
表1
消息类型 标识 优先级
周期性广播消息类型 ID1 1
事件触发消息类型 ID2 2
消息业务类型1 ID3 3
… … …
值得注意的是，表1仅示意性示出了几种实例，但本发明不限于此。其中，消息类型的优先级可以是小区特定的(cell-specific)，也可以是UE特定的(UE-specific)。例如在UE-specific的情况下，同一消息类型对于不同的UE来说，可以具有不同的优 先级。
在本实施例中，消息中包括数据信息，数据信息可以与例如下行控制信息(DCI，Downlink Control Information)相关联；DCI中例如指示了发送给该UE的数据信息所占用的时频资源等，UE根据DCI中的信息才能接收该数据信息，从而获取消息的内容。本发明实施例可以使用消息类型所对应的标识对消息的DCI进行加扰，具体如何传输消息(数据信息)以及控制信息、如何对DCI进行加扰或解扰可以参考相关技术，本发明不再赘述。
图2是本发明实施例的消息发送方法的另一示意图，以基站为例进行说明。如图2所示，消息发送方法可以包括：
步骤201，基站根据预设信息或者用户设备上报的辅助信息确定用户设备偏好的消息类型。
在本实施例中，基站可以根据预设信息预先确定小区内各个用户设备偏好(或希望)的消息类型。例如UE1偏好周期性广播消息类型，UE2偏好事件触发消息类型，UE3偏好消息业务类型1，等等。
此外，基站也可以根据用户设备上报的辅助信息中的偏好消息类型(或者还可以包括优先级)确定小区内各个用户设备偏好的消息类型。例如，UE1上报偏好的消息类型为周期性广播消息类型和消息业务类型2，则基站确定UE1偏好的消息类型为周期性广播消息类型和消息业务类型2。
此外，基站还可以根据用户设备上报的辅助信息中的用户设备类型和/或用户设备位置确定小区内各个用户设备偏好的消息类型。例如，在V2X通信中，UE1上报用户设备类型为P-UE(Pedestrian UE)类型，则基站可以确定UE1偏好的消息类型为事件触发消息类型；再例如，在V2X通信中，UE2上报位置信息，则基站可以确定UE2偏好的消息为距离该UE2m米范围内的V-UE(Vehicle UE)发送的消息。
值得注意的是，以上仅示意性地说明了如何确定用户设备偏好的消息类型，但本发明不限于此，还可以根据实际情况确定具体的实施方式。关于用户设备上报辅助信息的情况将在下文进行说明。
步骤202，基站判断待发送的两个或两个以上消息的内容是否相同或相似；
步骤203，基站在所述两个或两个以上消息的内容相同或相似的情况下，将所述两个或两个以上消息合并为一个消息。
在本实施例中，通过合并相同或相似的消息，基站可以减少消息发送量，从而缓解空口拥塞的问题。
步骤204，基站确定待发送给一个或多个用户设备的某一消息的消息类型；
步骤205，基站根据所述消息的消息类型判断小区内是否存在用户设备偏好所述消息；如果小区内没有任何用户设备偏好该消息类型的消息，则丢弃或不发送该消息；如果小区内至少有一个用户设备偏好该消息类型的消息，则执行步骤206。
在本实施例中，基站根据步骤201可以获知小区内的各个用户设备分别偏好哪些消息类型(用户设备如果偏好某一种消息类型，则偏好该消息类型的消息)；然后根据基于步骤204的该消息的消息类型，可以确定小区内的哪些用户设备偏好该消息而哪些用户设备不偏好该消息。
在本实施例中，如果小区内没有任何用户设备偏好该消息类型的消息，则丢弃或不发送该消息；由此基站可以不必发送用户设备均不偏好的消息，可以减少消息发送量，从而缓解空口拥塞的问题。
步骤206，基站采用该消息类型所对应的标识对该消息的控制信息进行加扰；其中不同的标识对应不同的消息类型；
步骤207，基站向一个或多个用户设备发送该消息的数据信息以及加扰后的控制信息。
值得注意的是，图2仅示意性地对本发明实施例进行了说明，但本发明不限于此。例如可以适当地调整各个步骤之间的执行顺序，此外还可以增加其他的一些步骤或者减少其中的某些步骤。例如在只有一个待发送消息的情况下可以省略步骤202和步骤203。本领域的技术人员可以根据上述内容进行适当地变型，而不仅限于上述附图2的记载。
以上对于网络设备如何发送消息进行了示意性说明，以下说明如何根据用户设备上报的辅助信息或者预设信息来分配标识和/或反馈接收等级。
图3是本发明实施例的标识分配的示意图，示出了某一用户设备进行上报的情况。如图3所示，该标识分配的过程可以包括：
步骤301，基站接收用户设备上报的辅助信息。
在本实施例中，所述辅助信息可以包括如下信息的一种或者多种：用户设备的类型信息、用户设备偏好的消息类型信息、用户设备偏好的消息类型的优先级信息、用 户设备的位置信息、用户设备的电量状态信息、用户设备的电量等级信息。
值得注意的是，以上的辅助信息可以由用户设备在应用层或物理上行共享信道(PUSCH，Physical Uplink Shared Channel)多次上报。
例如，用户设备偏好的消息类型信息和/或该消息类型信息的优先级信息可以在用户设备接入网络时上报，或者通过周期性方式上报，或者在信息(该消息类型信息和/或该优先级信息)发生变更时上报；
用户设备的类型信息可以在所述用户设备接入网络时上报；
用户设备的位置信息可以通过周期性方式上报，或者在所述用户设备从小区的某一区域进入另一区域时上报，或者在所述用户设备的移动距离达到预设阈值(例如X米)时上报；
用户设备的电量状态信息和/或电量等级信息可以通过周期性方式上报，或者在信息(该电量状态信息和/或电量等级信息)发生变更时上报。
步骤302，基站根据用户设备上报的辅助信息，为一个或多个消息类型分配对应的标识。
步骤303，基站向用户设备发送对应于消息类型的标识和/或所述标识的优先级。
在本实施例中，基站接收到用户设备上报的辅助信息后，可以根据偏好的消息类型及其优先级等信息分配对应的标识(Group-ID)。若上报的消息类型均已分配了Group-ID，则基站可以直接向用户设备反馈相应的Group-ID及Group-ID优先级；若上报的部分或全部消息类型尚未分配Group-ID，则基站可以分别为每一个未分配Group-ID的消息类型分配一个Group-ID，并向用户设备反馈与其偏好的消息类型对应的Group-ID及Group-ID优先级。
图4是本发明实施例的标识分配的另一示意图，如图4所示，标识分配的过程可以包括：
步骤401，基站根据预设信息为一个或多个消息类型分配对应的标识。
步骤402，基站向用户设备发送对应于消息类型的标识和/或所述标识的优先级。
在本实施方式中，基站可以预配置消息类型及其优先级，以及相应地分配对应的Group-ID，然后可以通过广播告知小区内的用户设备。
图3和图4示意性说明了分配消息类型所对应的标识的情况。值得注意的是，上述Group-ID的优先级顺序可以显式地被指示，也可以隐含在Group-ID反馈的顺序中。 此外，基站还可以配置通用Group-ID，用以加扰需要所有用户设备接收的消息的DCI。
在本实施例中，在用户设备上报的辅助信息中包括电量状态信息和/或电量等级信息的情况下，基站还可以根据确定该用户设备的接收等级。
图5是本发明实施例的反馈接收等级的示意图，如图5所示，反馈接收等级的过程可以包括：
步骤501，基站接收用户设备上报的辅助信息，其中该辅助信息包括用户设备的电量状态信息和/或电量等级信息；
步骤502，基站根据辅助信息中的电量状态信息和/或电量等级信息，确定所述用户设备的接收等级。
如图3所示，该方法还可以包括：
步骤503，基站向该用户设备发送该接收等级。
值得注意的是，图3至5仅示意性地对本发明实施例进行了说明，但本发明不限于此。例如可以适当地调整各个步骤之间的执行顺序，此外还可以增加其他的一些步骤或者减少其中的某些步骤。此外，图3至图5的内容可以组合起来实施，也可以与图2结合起来。本领域的技术人员可以根据上述内容进行适当地变型，而不仅限于上述附图2至5的记载。
由上述实施例可知，网络设备通过消息类型所对应的标识对消息的控制信息进行加扰，用户设备通过消息类型所对应的标识对消息的控制信息进行解扰，在控制信息解扰成功的情况下才继续接收数据信息；由此用户设备可以对不偏好的消息不继续处理，降低用户设备的功耗。
此外，网络设备还可以过滤掉用户设备不偏好的消息，或者合并相同或相似的消息；由此基站可以减少消息发送量，从而缓解空口拥塞的问题。
实施例2
本发明实施例提供一种消息接收方法，从用户设备一侧进行说明，本发明实施例与实施例1相同的内容不再赘述。
图6是本发明实施例的消息接收方法的示意图，如图6所示，消息接收方法包括：
步骤601，用户设备采用消息类型所对应的标识对接收到的控制信息进行解扰；其中不同的标识对应不同的消息类型；
步骤602，用户设备在成功解扰该控制信息的情况下，接收所述控制信息所关联的数据信息。
在本实施例中，消息类型与标识的对应关系可以预先被配置，或者由基站根据用户设备上报的辅助信息而被配置。其中，在所述标识有多个的情况下，可以根据所述标识的优先级对接收到的控制信息进行解扰。
例如，按照优先级依次使用不同的标识对DCI进行解扰；可以首先使用优先级最高的标识对DCI进行解扰，如果解扰成功则继续接收该DCI关联的数据信息，如果解扰不成功则使用优先级第二高的标识对该DCI进行解扰，以此类推；如果该用户设备所有的标识均不能成功解扰该DCI，则表明该DCI关联的消息不属于该用户设备偏好的消息类型，则不再继续对该消息进行处理。由此，用户设备可以对偏好的消息类型按照优先级依次接收消息，降低用户设备的功耗。
图7是本发明实施例的消息接收方法的另一示意图，仍以基站为例进行说明。如图7所示，消息接收方法包括：
步骤701，用户设备接收基站发送的对应于消息类型的标识和/或所述标识的优先级。
在本实施例中，对应于消息类型的标识可以为一个或多个。消息类型与标识的对应关系可以由基站预先配置，或者也可以由基站根据用户设备上报的辅助信息而配置。
例如，用户设备接收到的标识为：ID1(对应优先级1)、ID2(对应优先级2)、ID3(对应优先级3)。
步骤702，用户设备确定接收等级；
在本实施例中，用户设备可以根据当前电量状态和/或当前电量等级来确定所述用户设备的接收等级，或者也可以根据从基站接收到的接收等级信息确定所述用户设备的接收等级。
例如，当前电量状态为60％，则确定当前用户设备的接收等级为2。
步骤703，用户设备接收基站发送的某一控制信息。
步骤704，用户设备使用优先级高于或等于所述接收等级的一个或多个标识，对接收到的控制信息进行解扰；
例如，可以使用ID2和ID3(优先级均高于或等于2)对DCI进行解扰。
步骤705，用户设备在成功解扰该控制信息的情况下，接收所述控制信息所关联的数据信息。
