背景技术
为了提高传输覆盖的范围，可以在发送端和接收端之间引入中继(relay)，中继可以转发从基站接收到的数据，从而扩大基站的覆盖范围。
通常，一个用户设备通过一个中继设备和基站通信时，需要知道和中继设备连接的基站所采用的无线接入技术(Radio Access Technology，RAT)。
当中继设备和用户设备之间使用物物直连通信技术，而中继设备和网络设备之间还是使用传统的上下行通信技术，尤其是引入新的边链路技术后，协议不仅支持中继设备和长期演进(Long Term Evolution，LTE)网络连接，还要支持中继设备和新空口(New Radio，NR)网络连接，也即中继设备既可以采用LTE无线接入技术接入基站，也可以采用NR无线接入技术接入基站。
然而，现有技术中，当中继设备存在多种无线接入技术与基站通 信时，用户设备无法得知中继设备和基站之间到底是通过哪种无线接入技术连接，也即无法判断基站所使用的无线接入技术，从而导致用户设备无法确定采用哪种无线接入技术进行和基站的通信。

具体实施方式
物物直连通信技术或边链路通信技术是不同于普通无线蜂窝网络通信的通信技术。在传统的蜂窝网络中，用户设备和基站备进行通信，此时用户设备和基站之间的链路被称为上行(Uplink)或下行链路(Downlink)，接口被称为Uu接口，而在物物直连通信中，用户设备直接和用户设备进行通信，用户设备和用户设备之间的链路称为直连链路(sidelink，SL)，接口被称为PC5接口。
中继是一种覆盖增强技术，中继可以将从基站接收到的数据，转发出去，从而扩大基站的覆盖范围。在LTE(Long Term Evolution，长期演进)网络中，传统的中继设备和用户设备之间采用的无线通信技术，与中继设备与基站设备采用的通信技术是相同的，对用户设备而言，中继设备就像是一个基站。当一个用户设备检测到中继设备的同步信号或广播信号时，可以获知中继设备采用的RAT，从而也就知道了基站设备采用的RAT，从而用户设备可以采用相应的RAT与基站进行通信。
在3GPP Rel-13版本中，引入了一种新的中继技术，在这种新的中继技术中，中继设备和终端设备之间使用的是物物直连通信技术，而中继设备和网络设备之间使用还是传统的上下行通信技术，这时， 通过中继发送的同步信号、广播信号、发现信号是无法知道网络设备采用的无线接入技术的。但是此时，由于协议只支持中继设备和4G(LTE)网络连接，所以用户设备可以默认只要有可用的中继设备，那该中继设备接入的必然是LTE的基站，也就是演进节点B(Evolved Node B，eNB)。
在3GPP Rel-16中，引入了新的边链路技术，同时，将会在3GPP Rel-17中，支持基于此新边链路技术的中继技术，然而此时，协议不仅要支持中继设备和LTE网络连接，还要支持和5G(NR)网络连接，然而此时，仅通过接收中继设备的现有信息，是无法得知中继设备和基站之间的无线接入技术，从而导致用户设备无法确定采用哪种无线接入技术进行和基站的通信。
在本发明实施例中，用户设备根据中继设备发送的RAT指示信息，确定中继设备所在服务小区所属基站使用的RAT类型，从而可以采用与基站使用的RAT类型相适配的RAT，与中继设备的服务小区所属的基站进行通信。
为使本发明实施例的上述目的、特征和有益效果能够更为明显易懂，下面结合附图对本发明的具体实施例做详细的说明。
参照图1，给出了本发明实施例中的一种中继设备所在服务小区的RAT获取方法的流程图，具体可以包括如下步骤：
步骤11，接收中继设备发送的RAT指示信息。
在具体实施中，在用户设备与基站之间设置有中继设备时，中继设备可以发送RAT指示信息，RAT指示信息用于指示中继设备所在服务小区的RAT信息。当用户设备处于中继设备的信号覆盖范围内时，可以接收到中继设备发送的RAT指示信息。
在具体实施中，用户设备可以从多种类型的信息中获取到RAT指示信息中。
在本发明一实施例中，用户设备可以从直连链路系统信息中获取 RAT指示信息，也即RAT指示信息包含于直连链路系统信息中。直连链路系统信息可以封装为直连链路主信息块(Sidelink Master Information Block，SL-MIB)，也可以封装为直连链路系统信息块(Sidelink System Information Block，SL-SIB)。中继设备可以周期性的发送SL-MIB或SL-SIB。当RAT指示信息包含于直连链路系统信息，并被封装为SL-MIB时，用户设备可以从接收到的SL-MIB中获取到RAT指示信息。当RAT指示信息包含于直连链路系统信息，并被封装为SL-SIB时，用户设备可以从接收到的SL-SIB中获取到RAT指示信息。
在本发明另一实施例中，用户设备可以从发现信息(Discovery Message)中获取RAT指示信息，也即RAT指示信息包含于发现信息中。发现信息用于用户设备发现中继设备，或者用于中继设备发现用户设备。用户设备可以从接收到的发现信息中得到RAT指示信息。
在本发明又一实施例中，用户设备可以从直连链路无线资源控制(Sidelink Radio Resource Control，SL-RRC)信令中获取RAT指示信息，也即RAT指示信息包含于SL-RRC信令中，也即在SL-RRC信令中包括服务小区的RAT信息。SL-RRC信令可以为直连链路建立过程中的SL-RRC信令，如直连链路RRC连接建立消息，也可以为直连链路建立后的SL-RRC信令，如直连链路RRC连接重配消息。用户设备接收到SL-RRC信令后，可以从SL-RRC信令获取RAT指示信息。
在本发明再一实施例中，用户设备可以从中继设备发送的基站的系统信息中获取RAT指示信息，也即RAT指示信息包含于基站的系统信息中。中继设备可以转发基站的系统信息，用户设备可以获取基站的系统信息，根据基站的系统信息获取中继设备所在服务小区的RAT信息，其中，基站的系统信息可以封装为主信息块(Master Information Block，MIB)，也可以封装为系统信息块(System Information Block，SIB)。
步骤12，根据所述RAT指示信息，确定所述服务小区所属基站使用的RAT类型。
例如，RAT指示信息指示中继设备所在服务小区为LTE小区，则服务小区所属基站使用的RAT类型为LTE，也即在中继设备所在服务小区所属的基站能够提供LTE服务。又如，RAT指示信息指示中继设备所在服务小区为NR小区，则服务小区所属基站使用的RAT类型为NR，也即在中继设备所在服务小区所属的基站能够提供NR服务。
在具体实施中，当RAT指示信息包含于基站的系统信息中，用户设备可以根据基站的系统信息的内容确定服务小区所属基站所使用的RAT类型。例如，中继设备转发基站的系统信息时，基站的系统信息本身携带RAT指示信息。又如，基站的系统信息里没有携带RAT指示信息，中继设备在转发时，在基站的系统信息里添加基站的RAT信息，并发送添加了基站的RAT信息之后的基站的系统信息。
在具体实施中，由于LTE的系统信息和NR的系统信息大小(比如占用的比特数)不同，因此，用户设备也可以根据基站的系统信息的大小确定服务小区所属基站所使用的RAT类型。
在具体实施中，当根据基站的系统信息的大小确定基站所使用的RAT类型时，用户设备可以将接收到的基站的系统信息与预设的各类型标准系统信息分别进行比较，根据比较结果确定所述服务小区的RAT类型，根据服务小区的RAT类型，确定基站使用的RAT类型。
在本发明一实施例中，基站的系统信息封装为MIB，各类型标准系统信息包括标准LTE MIB及标准NR MIB。用户设备可以将从中继设备处接收到的基站的MIB分别与标准LTE MIB及标准NR MIB进行比较，当基站的MIB与标准LTE MIB大小相同时，确定服务小区为LTE小区；当基站的MIB与标准NR MIB大小相同时，确定服务小区为NR小区。
在本发明另一实施例中，基站的系统信息封装为SIB，各类型标准系统信息包括标准LTE SIB及标准NR SIB。用户设备可以将从中继设备处接收到的基站的SIB分别与标准LTE SIB及标准NR SIB进行比较，当基站的SIB与标准LTE SIB大小相同时，确定所服务小区为LTE小区，当基站的SIB与标准NR SIB大小相同时，确定服务小区为NR小区。
可以理解的是，基站与中继设备，基站与用户设备之间采用的通信系统，并不局限于所列举的5G(5Generation)通信系统以及4G通信系统，还可以适用于已有的3G通信系统，以及未来新的各种通信系统，如6G、7G等。根据所使用的通信系统的类型不同，基站使用的RAT类型也不同。中继设备与用户设备之间采用的通信技术也不局限于所列举的边链路技术、物物直连通信技术，也可以为3G、4G、5G、6G、7G等。
步骤13，采用与所述基站使用的RAT类型相适配的RAT，与所述基站进行通信。
在具体实施中，用户设备确定基站所使用的RAT类型之后，可以采用与基站适配的RAT与基站进行通信。
在本发明一实施例中，用户设备采用与基站的RAT类型相同的RAT与基站进行通信。
例如，基站在中继设备所在的服务小区使用LTE无线接入技术时，用户设备采用LTE无线接入技术和基站进行通信。
又如，基站在中继设备所在的服务小区使用NR无线接入技术时，用户设备采用NR无线接入技术和基站进行通信。
在本发明另一实施例中，用户设备采用与基站的RAT类型不相同但适配且兼容的RAT，与基站进行通信。
由上可知，中继设备发送用于指示中继设备所在服务小区的RAT信息的指示信息，用户设备根据中继设备发送的RAT指示信息，确 定中继设备所在服务小区所属基站使用的RAT类型，从而可以采用与基站使用的RAT类型相适配的RAT，与中继设备的服务小区所属的基站进行通信。
参照图2，本发明实施例还提供一种中继设备所在服务小区的RAT指示方法，具体可以包括如下步骤：
步骤21，获取中继设备所在服务小区的RAT信息。
在具体实施中，当中继设备接入基站时，可以通过基站发送的同步信号、广播信号等获取所在服务小区的RAT信息，也即获取所通信连接的基站采用的RAT。
步骤22，发送RAT指示信息。
在具体实施中，RAT指示信息用于指示中中继设备的服务小区的RAT信息。中继设备可以通过多种方式发送RAT指示信息。
在本发明一实施例中，将RAT指示信息包含于直连链路系统信息、发现信息及SL-RRC信令等任一种信息中发送。
例如，将RAT指示信息包含于直连链路系统信息，并将直连链路系统信息封装为SL-MIB，或者封装为SL-SIB。中继设备通过周期性的发送SL-MIB或SL-SIB。当RAT指示信息包含于SL-MIB时，在中继设备的信号覆盖范围内，用户设备可以从接收到的SL-MIB中获取到RAT指示信息。当RAT指示信息包含于SL-SIB时，在中继设备的信号覆盖范围内，用户设备可以从接收到的SL-SIB中获取到RAT指示信息。
又如，发现信息包括RAT指示信息。
再如，RAT指示信息包含于SL-RRC信令中。中继设备可以在与用户设备建立连接过程中，向用户设备发送包括RAT指示信息的SL-RRC信令。中继设备也可以在直连链路建立后的SL-RRC信令中发送RAT指示信息，如在直连链路RRC连接重配消息中发送RAT 指示信息。
在本发明另一实施例中，将RAT指示信息包含于基站的系统信息，中继设备转发基站的系统信息。
基站的系统信息可以封装为MIB，也可以封装为SIB。SIB信息有多个，从1开始编号，如SIB1，SIB2，SIB3等。
例如，中继设备转发基站的MIB，用户设备将从中继设备收到的转发自基站的MIB分别和LTE MIB以及和NR MIB进行大小比较，若基站的MIB和LTE MIB大小相同，则判断中继设备所在的服务小区为LTE小区，若基站的MIB和NR MIB大小相同，则判断中继设备所在的服务小区为NR小区。
又如，中继设备转发基站的SIB1，用户设备将从中继设备收到的转发自基站的SIB1分别和LTE SIB1以及和NR SIB1进行大小比较，若基站的SIB1和LTE SIB1大小相同，则判断中继设备所在的服务小区为LTE小区，若基站的SIB1和NR SIB1大小相同，则判断中继设备所在的服务小区为NR小区。
再如，用户设备可以根据基站的系统信息的内容确定基站在中继设备所在服务小区使用的RAT类型。
在具体实施中，中继设备可以直接转发基站的系统信息，也可以对基站的系统信息进行修改之后，并发送修改后的系统信息，修改后的系统信息可以通过内容或者大小等方式来标识不同RAT的类型。例如，中继设备转发基站的系统信息时，基站的系统信息本身携带RAT指示信息。又如，基站的系统信息里没有携带RAT指示信息，中继设备在转发时，在基站的系统信息里添加基站的RAT信息，并发送添加了基站的RAT信息之后的基站的系统信息。
在具体实施中，用户设备根据RAT指示信息，确定服务小区所基站使用的RAT类型之后，可以采用与基站使用的RAT类型相适配的RAT，与基站进行通信。
由上可知，中继设备通过发送RAT指示信息，对中继设备所在的服务小区的RAT进行指示，以使得中继设备的信号覆盖范围内的用户设备在接收到RAT指示信息后，可以根据RAT指示信息获取到中继设备所在服务小区所属的基站的RAT类型，从而采用与基站的RAT类型相适配的RAT与基站进行通信。
