Description

一种监测方法、监测装置及存储介质A monitoring method, monitoring device and storage medium

技术领域technical field

本公开涉及无线通信技术领域，尤其涉及一种监测方法、监测装置及存储介质。The present disclosure relates to the technical field of wireless communication, and in particular to a monitoring method, a monitoring device and a storage medium.

背景技术Background technique

工作在非频谱上的设备在发送数据之前，需要进行信道监听，信道的监听是以监听避让(listen before talk，LBT)子带为单元的来进行的。在监听到的信道为空闲状态的情况下，可以进行数据的发送。在新一代通信技术中，引入能力缩减(Reduced capability，Redcap)终端。在相关技术中，Redcap终端是工作在授权频谱的。而一般工业传感器等主要是在工业领域应用，工业领域使用的主要是非授权频谱，因此，需要Redcap终端也可以工作在非授权频谱上。Devices working on non-spectrum need to perform channel monitoring before sending data, and channel monitoring is performed in units of listen before talk (LBT) subbands. When the monitored channel is idle, data can be sent. In the new generation communication technology, a reduced capability (Reduced capability, Redcap) terminal is introduced. In the related technology, the Redcap terminal works in the licensed frequency spectrum. General industrial sensors are mainly used in the industrial field, and the unlicensed spectrum is mainly used in the industrial field. Therefore, it is necessary for the Redcap terminal to also work on the unlicensed spectrum.

但是，Redcap终端的带宽受限，工作在非授权频谱时，只能监听一个信道。当监听的信道被占用时，则无法与网络设备进行通信。因此，Redcap终端工作在非授权频谱受阻的概率非常大。However, the bandwidth of the Redcap terminal is limited, and when working in an unlicensed spectrum, it can only monitor one channel. When the monitored channel is occupied, it cannot communicate with network devices. Therefore, there is a high probability that Redcap terminals will be blocked from working in unlicensed spectrum.

由于物联网蓬勃发展，为人类的生活和工作带来了诸多便利。其中，机器类通信技术 (Machine Type Communication，MTC)，窄带物联网技术(Narrow band Internet of thing，NB-IoT)是蜂窝物联网技术的典型代表。目前这些技术已经广泛用于智慧城市(例如抄表)、智慧农业(例如温度湿度等信息的采集)以及智慧交通(例如共享单车)等诸多领域。Due to the vigorous development of the Internet of Things, it has brought many conveniences to human life and work. Among them, machine type communication technology (Machine Type Communication, MTC), narrowband Internet of things technology (Narrow band Internet of things, NB-IoT) are typical representatives of cellular Internet of things technology. At present, these technologies have been widely used in many fields such as smart cities (such as meter reading), smart agriculture (such as the collection of information such as temperature and humidity), and smart transportation (such as shared bicycles).

在通信***中，针对物联网业务中，低速率高时延等场景(比如，抄表，环境监测等场景)，相关技术提出MTC和NB-IoT两大技术。目前NB-IoT技术最大可以支持几百K的速率，MTC最大可以支持几M的速率。然而随着物联网业务(例如，监控、智能家居、可穿戴设备和工业传感器检测等业务)的不断发展，一般地要求几十到一百M的速率，并且对时延的要求也相对提高。因此在通信***中，MTC和NB-IoT两大技术已经不能满足当前物联网业务的要求。同时在另一方面中，MTC和NB-IoT两大技术一般部署在地下室，野外等不容易充电或者不容易更换电池的场景中，因此与MTC和NB-IoT两大技术相关联的终端受到硬件限制，导致覆盖能力不如一般的无线通信终端。并且由于应用环境的影响，其设备的功率节省也是MTC和NB-IoT两大技术的特性。基于这种情况，开始提出了在5G NR中再设计一种新的用户设备，用以来覆盖这种中端物联网设备的要求。在目前的3GPP(3rd Generation Partnership Project，第三代合作伙伴项目)标准化中，这种新的终端类型叫做Redcap终端或者简称为NR-lite(精简版新空口)。In the communication system, for scenarios such as low-speed and high-delay in the Internet of Things business (such as meter reading, environmental monitoring, etc.), related technologies propose two major technologies: MTC and NB-IoT. At present, NB-IoT technology can support a maximum rate of several hundred K, and MTC can support a maximum rate of several M. However, with the continuous development of Internet of Things services (for example, monitoring, smart home, wearable devices, and industrial sensor detection services), the speed of tens to 100 M is generally required, and the requirement for delay is also relatively high. Therefore, in the communication system, the two major technologies of MTC and NB-IoT can no longer meet the requirements of the current Internet of Things business. At the same time, on the other hand, MTC and NB-IoT are generally deployed in the basement, in the field and other scenarios where it is not easy to charge or replace the battery. Therefore, the terminals associated with MTC and NB-IoT are subject to hardware Due to the limitation, the coverage ability is not as good as that of general wireless communication terminals. And due to the influence of the application environment, the power saving of its equipment is also a characteristic of the two major technologies of MTC and NB-IoT. Based on this situation, it is proposed to design a new user equipment in 5G NR to cover the requirements of this mid-end IoT device. In the current 3GPP (3rd Generation Partnership Project, third-generation partnership project) standardization, this new terminal type is called Redcap terminal or NR-lite (simplified new air interface) for short.

工作在非频谱上的设备在发送数据之前，需要进行信道监听，当监听的信道为空闲状态的时候，才可以进行数据的发送。在NR***中，信道的监听都是以LBT子带为单元来进行的，其中，相关技术中一个LBT子带的宽度是20MHz。若监听带该LBT子带被占用，则不再该LBT子带上发送数据。而终端所监测的BWP中包括多个LBT子带，若终端监听到其中部分LBT子带被占用(即为忙时)的，则可以在其他空闲LBT子带上进行数据的收发，从而可以避免长时间无法进行收发。Devices working on non-spectrum need to monitor the channel before sending data. When the monitored channel is idle, data can be sent. In the NR system, channel monitoring is carried out in units of LBT subbands, wherein in the related art, the width of one LBT subband is 20 MHz. If the LBT subband of the listening band is occupied, no data is sent on the LBT subband. The BWP monitored by the terminal includes multiple LBT subbands. If the terminal detects that some of the LBT subbands are occupied (that is, when it is busy), it can send and receive data on other idle LBT subbands, thereby avoiding Unable to send and receive for a long time.

在新一代通信技术中，引入Redcap终端，Redcap终端都是工作在授权频谱的。而一般工业传感器等主要是在工业领域应用，工业领域使用的主要是非授权频谱，因此，需要Redcap终端也可以工作在非授权频谱上。但是，Redcap终端的带宽受限，例如在一个FR1下一个Redcap终端可以监测20MHz，即工作在非授权频谱时，只能监听一个信道，即一次只能监听一个LBT子带。若监听的LBT子带被占用，则不可以进行数据的收发，Redcap终端就无法与基站进行通信。与其他终端相比，Redcap终端通信受阻的概率会更大。In the new generation of communication technology, Redcap terminals are introduced, and the Redcap terminals all work in the licensed spectrum. General industrial sensors are mainly used in the industrial field, and the unlicensed spectrum is mainly used in the industrial field. Therefore, it is necessary for the Redcap terminal to also work on the unlicensed spectrum. However, the bandwidth of the Redcap terminal is limited. For example, a Redcap terminal under FR1 can monitor 20MHz, that is, when working in an unlicensed spectrum, it can only monitor one channel, that is, it can only monitor one LBT subband at a time. If the monitored LBT subband is occupied, data cannot be sent and received, and the Redcap terminal cannot communicate with the base station. Compared with other terminals, the Redcap terminal has a higher probability of being blocked in communication.

基于此本公开提供一种监测方法，针对带宽受限的终端配置至少一个LBT子带，以避免一个LBT子带受阻时，终端与网络设备无法通信的问题。Based on this, the present disclosure provides a monitoring method, which configures at least one LBT subband for a terminal with limited bandwidth, so as to avoid the problem that the terminal cannot communicate with the network device when one LBT subband is blocked.

在本公开实施例中，终端确定网络设备为其配置的至少一个LBT子带，LBT子带为终端进行信道监测的基本频率资源单位。至少一个LBT子带可以使得工作在非授权频谱的终端监测PDCCH。其中本公开实施例涉及的终端可以是Redcap终端，当然也可以是其他类型终端。In the embodiment of the present disclosure, the terminal determines at least one LBT subband configured for it by the network device, and the LBT subband is a basic frequency resource unit for the terminal to perform channel monitoring.

The terminal involved in the embodiments of the present disclosure may be a Redcap terminal, and of course may also be other types of terminals.

其中多个BWP中每个所述BWP包括一个或多个LBT子带。Each of the multiple BWPs includes one or more LBT subbands.

在本公开一些实施例中，网络设备可以为终端配置多个BWP，每个BWP包括一个LBT子带。当然，每个BWP还可以包括多个LBT子带，再次不做具体限定。In some embodiments of the present disclosure, the network device may configure multiple BWPs for the terminal, and each BWP includes one LBT subband. Of course, each BWP may also include multiple LBT subbands, again not specifically limited.
