The content is incorporated herein by reference.
本发明涉及通信技术领域,具体而言,涉及一种在非授权频段上识别运营商标识的方法、一种在非授权频段上识别运营商标识的装置和一种终端。The present invention relates to the field of communications technologies, and in particular, to a method for identifying an operator identifier on an unlicensed frequency band, an apparatus for identifying an operator identifier on an unlicensed frequency band, and a terminal.
目前,随着移动业务的快速发展,现有的分配给移动业务的无线频谱的容量已经无法满足要求了。在3GPP Rel-13阶段,一种称作LAA(Licensed-Assisted Access,辅助接入技术)的机制被引入,在LAA机制中,移动通信的传输可以在非授权频谱上承载,如5GHz的频段,而目前使用这些非授权频谱的主要是Wi-Fi、蓝牙、雷达、医疗等系统在使用。At present, with the rapid development of the mobile service, the capacity of the existing wireless spectrum allocated to the mobile service cannot meet the requirements. In the 3GPP Rel-13 phase, a mechanism called LAA (Licensed-Assisted Access) is introduced. In the LAA mechanism, the transmission of mobile communication can be carried on the unlicensed spectrum, such as the 5 GHz band. Currently, these unlicensed spectrums are mainly used by Wi-Fi, Bluetooth, radar, medical and other systems.
由于非授权频谱上系统的多样性和复杂性,直接把LTE(Long Term Evolution,长期演进)的机制用于非授权频谱上是无法保证用户的安全性以及连接的稳定性的。因此,在LAA的机制中,通过CA(Carrier Aggregation,载波聚合)机制,使用授权频谱来帮助非授权频谱上的接入。目前,在非授权频谱上使用LTE的话,系统可以有如下两种工作方式:一种是SDL(Supplemental Downlink,补充下行),即只有下行传输子帧;另一种是TDD(Time Division Duplex,时分双工)模式,既包含下行子帧、也包含上行子帧。Due to the diversity and complexity of the system on the unlicensed spectrum, the use of the LTE (Long Term Evolution) mechanism for the unlicensed spectrum cannot guarantee the security of the user and the stability of the connection. Therefore, in the mechanism of the LAA, the licensed spectrum is used to assist access on the unlicensed spectrum through a CA (Carrier Aggregation) mechanism. Currently, if LTE is used on the unlicensed spectrum, the system can work in the following two modes: one is SDL (Supplemental Downlink), that is, only downlink transmission subframes; the other is TDD (Time Division Duplex). Duplex mode, which includes both downlink subframes and uplink subframes.
在传统的LTE的网络部署的场景下,终端需要知道服务小区的cell ID,以便后续解调控制时使用。终端可以通过检测服务小区广播的PSS(Primary Synchronization Signal,主同步信号)和SSS(Secondary Synchronization Signal,辅同步信号)来获得服务小区的cell ID。同样的,终端在检测邻区的RSRP(Reference Signal Receiving Power,参考信号接收功率)或是RSRQ
(Reference Signal Receiving Quality,参考信号接收质量)时,在上报的过程中也需要将RSRP或是RSRQ的结果与对应的cell ID的一起上报给服务小区。In the scenario of traditional LTE network deployment, the terminal needs to know the cell ID of the serving cell for subsequent demodulation control. The terminal can obtain the cell ID of the serving cell by detecting a PSS (Primary Synchronization Signal) and an SSS (Secondary Synchronization Signal) broadcasted by the serving cell. Similarly, the terminal is detecting the RSRP (Reference Signal Receiving Power) of the neighboring cell or the RSRQ.
(Reference Signal Receiving Quality), in the process of reporting, the result of RSRP or RSRQ is also reported to the serving cell together with the corresponding cell ID.
另外,在非授权频段上需要公平的去共享资源,因此在占用信道资源之前,需要去监听信道资源的空闲与否,然后才能去占用资源。在占用资源以后,终端需要进行服务小区和临小区的RRM(Radio Resource Management,无线资源管理)测量。由于非授权频段上小区的工作状态是不确定的,因此可以考虑通过在3GPP Rel-12阶段引入的DRS(Discovery Reference Signal,发现参考信号)进行测量。而邻区和服务小区的DRS的传输的时频位置可能是不一样的。In addition, a fair de-shared resource is required on the unlicensed frequency band. Therefore, before occupying the channel resource, it is necessary to monitor the idleness of the channel resource before the resource can be occupied. After the resources are occupied, the terminal needs to perform RRM (Radio Resource Management) measurement of the serving cell and the neighboring cell. Since the working state of the cell on the unlicensed band is uncertain, measurement can be considered by DRS (Discovery Reference Signal) introduced in the 3GPP Rel-12 stage. The time-frequency position of the transmission of the DRS of the neighboring cell and the serving cell may be different.
在现有的LTE网络部署的情况下,不同的运营商会占用不同的授权频段,某个授权频段是分配给一个运营商独立使用的,因此运营商可以通过合理的网络部署来解决相邻小区之间的cell ID冲突的问题。而在非授权频谱上,由于频段可能是多个运营商共享使用的,并且多个运营商之间可能不会协调网络部署,因此可能会出现相邻小区之间的cell ID是冲突的情况,在这种情况下,可能会导致终端在上报测量结果时候出现的混淆的问题。In the case of the existing LTE network deployment, different operators will occupy different licensed frequency bands, and a certain licensed frequency band is allocated to an operator for independent use. Therefore, the operator can solve the neighboring cell through reasonable network deployment. The problem of cell ID conflicts between. On the unlicensed spectrum, since the frequency band may be shared by multiple operators, and the network deployment may not be coordinated among multiple operators, the cell ID between adjacent cells may be in conflict. In this case, it may cause confusion in the terminal when reporting the measurement results.
因此,如何能够在非授权频谱上,准确识别不同运营商的小区,避免终端在测量上报时由于cell ID碰撞导致混淆成为亟待解决的技术问题。Therefore, how to accurately identify the cells of different operators on the unlicensed spectrum, and avoid the confusion caused by the cell ID collision when the terminal reports the measurement becomes a technical problem to be solved.

以下结合图3A至图4详细说明本发明的技术方案。The technical solution of the present invention will be described in detail below with reference to FIGS. 3A to 4.
本发明主要是提出了一种应用于非授权频段的终端识别运营商标识的方法,可以有效避免终端在上报测量信息时由于cell ID碰撞带来的混淆问题。针对该问题,本发明主要提出了三种方法来进行解决,以下一一进行说明:
The present invention mainly proposes a method for identifying a carrier identifier by a terminal applied to an unlicensed frequency band, which can effectively avoid the confusion caused by the collision of the cell ID when the terminal reports the measurement information. In response to this problem, the present invention mainly proposes three methods for solving the problem, and the following ones are explained:
方法一:method one:
通过DRS的信令来识别,在这种方法下,不同的运营商可以通过不同的DRS的信令设计来进行识别。下面以两个运营商的部署场景来举例说明,具体的方法可以是:It is identified by the signaling of DRS. Under this method, different operators can identify by different signaling design of DRS. The following is an example of the deployment scenario of two operators. The specific method can be:
运营商1和运营商2的DRS中传输的信令的传输格式来进行区分,如图3A所示为运营商1的DRS中信令的传输格式,图3B所示为运营商2的DRS中信令的传输格式。其中,DRS中的PSS和SSS传输的位置对于运营商1和运营商2是不同的,因此终端可以在检测PSS和SSS的位置去区分。The transmission format of the signaling transmitted in the DRS of the operator 1 and the operator 2 is differentiated. As shown in FIG. 3A, the transmission format of the signaling in the DRS of the operator 1 is shown in FIG. 3B, and the DRS in the operator 2 is shown in FIG. 3B. The transmission format of the signaling. The location of the PSS and SSS transmission in the DRS is different for the operator 1 and the operator 2, so the terminal can distinguish between the locations where the PSS and the SSS are detected.
但是,终端需要服务小区来通知不同的运营商所使用的DRS的序列,这可以通过RRC信令、MAC(Medium Access Control,媒体接入控制)CE(Control Element,控制单元)或是物理层信令来实现。本领域的技术人员需要注意的是,图3A和图3B所示的仅是本发明的一个实施例下的DRS的传输格式,其中通过PSS和SSS的传输位置不同来进行区分,在具体的实现中还可以通过DRS的其他信令的传输位置来进行区分。However, the terminal needs the serving cell to notify the sequence of the DRS used by different operators, which can be through RRC signaling, MAC (Medium Access Control), CE (Control Element) or physical layer. Order to achieve. It should be noted by those skilled in the art that the transmission format of the DRS in one embodiment of the present invention is shown in FIG. 3A and FIG. 3B, in which the transmission position of the PSS and the SSS are different, and the specific implementation is implemented. It can also be distinguished by the transmission location of other signaling of the DRS.
方法二:Method Two:
通过关于DRS的配置来识别,在这种方法下,不同的运营商之间的DRS的配置可以是不一样的。以两个运营商的场景来举例说明如下:It is identified by the configuration of the DRS that the configuration of the DRS between different operators may be different under this method. Take the scenario of two operators as an example:
如图4所示,不同的运营商可以配资不同的DMTC,比如配置不同的DMTC的偏移值。在这种情况下,假定不同的运营商之间都是基于GPS进行同步,那么终端可以通过盲检DRS传输的位置来获知不同运营商的指示,或是服务基站向终端通知其他运营商的DRS传输的位置,以便终端在相应的位置上进行DRS的搜索以便获知是否有别的运营商的小区存在。服务基站需要通过RRC信令、MAC CE或是物理层信令通知终端在相应的位置上进行搜索。As shown in Figure 4, different operators can allocate different DMTCs, such as configuring offset values of different DMTCs. In this case, assuming that different operators are synchronized based on GPS, the terminal can blindly check the location of the DRS transmission to learn the indications of different operators, or the serving base station notifies the terminal of the DRS of other operators. The location of the transmission so that the terminal performs a DRS search at the corresponding location to know if there are other operators' cells present. The serving base station needs to notify the terminal to search at the corresponding location through RRC signaling, MAC CE or physical layer signaling.
方法三:Method three:
通过initial signal(起始信号)的传输来指示,目前在非授权频段上的数据传输之前,可能需要引入一个initial signal来进行资源的预留以及其他的功能,因此可以考虑在initial signal中引入运营商的指示。The transmission of the initial signal indicates that it is necessary to introduce an initial signal for resource reservation and other functions before data transmission on the unlicensed band. Therefore, it is considered to introduce operation in the initial signal. Business instructions.
具体来说,可以通过不同的运营商使用不同的initial signal的序列来实现。这种情况下不同的运营商之间可能需要协调使用的序列池,这个协调可以是非
常静态的,比如可以通过预先定义两个序列池,两个不同的运营商只占用其中的一个序列池以便实现不同的运营商使用的序列是不一样的,这样终端可以通过检测initial signal的序列值来获知来区分不同的运营商。Specifically, it can be implemented by different operators using different sequences of initial signals. In this case, the sequence pools that need to be coordinated between different operators may be used. This coordination may be non-
Often static, for example, two sequence pools can be pre-defined. Two different operators only occupy one of the sequence pools so that the sequences used by different operators are different, so that the terminal can detect the sequence of the initial signal. Values are learned to distinguish between different operators.
通过本发明上述实施例的技术方案可以有效的实现终端在检测时,能够正确的识别有相同cell ID的两个或多个小区,因而在做测量上报时,基站可以知道测量的小区到底是不是本运营商下的小区,以便后续的操作。The technical solution of the foregoing embodiment of the present invention can effectively realize that two or more cells with the same cell ID can be correctly identified by the terminal during detection. Therefore, when performing measurement reporting, the base station can know whether the measured cell is in the end or not. The cell under this operator for subsequent operations.

以上结合附图详细说明了本发明的技术方案,考虑到在非授权频谱上,由于频段可能是多个运营商共享使用的,并且多个运营商之间可能不会协调网络部署,因此可能会出现相邻小区之间的cell ID是冲突的情况,在这种情况下,可能会导致终端在上报测量结果时候出现的混淆的问题。因此,本发明提出了一种新的在非授权频段上识别运营商标识的方案,可以确保终端在非授权频段上准确识别到不同运营商的小区,避免了终端在上报测量信息时由于cell ID碰撞导致混淆的问题。The technical solution of the present invention is described in detail above with reference to the accompanying drawings. Considering that in the unlicensed spectrum, since the frequency band may be shared by multiple operators, and the network deployment may not be coordinated among multiple operators, it may be In the case where the cell ID between adjacent cells is a conflict, in this case, the terminal may be confused when reporting the measurement result.
