For ease of description, this disclosure will sometimes simply refer to a wireless communication network as a network.

Further, the network devices referred to in this disclosure may also be referred to as radio access network devices. The radio access network device may be: a base station, an evolved node B (enb), a home base station, an Access Point (AP), a wireless relay node, a wireless backhaul node, a Transmission Point (TP), a Transmission and Reception Point (TRP) in a wireless fidelity (WIFI) system, and the like, and may also be a gNB in an NR system, or may also be a component or a part of a device constituting the base station.

Currently, some examples of terminals are: a smart Phone (Mobile Phone), a Pocket Computer (PPC), a palm top Computer, a Personal Digital Assistant (PDA), a notebook Computer, a tablet Computer, a wearable device, or a vehicle-mounted device, etc. Furthermore, when being a communication system of the internet of vehicles (V2X), the terminal device may also be a vehicle-mounted device.

It is to be understood that although the terms first, second, third, etc. may be used herein to describe various information in the embodiments of the present disclosure, such information should not be limited by these terms. These terms are only used to distinguish one type of information from another. For example, first information may also be referred to as second information, and similarly, second information may also be referred to as first information, without departing from the scope of embodiments of the present disclosure. The word "if" as used herein may be interpreted as "at … …" or "when … …" or "in response to a determination", depending on the context.

Due to the vigorous development of the Internet of things, great convenience is brought to human life and work. Among them, Machine Type Communication (MTC) and narrowband Internet of things (NB-IoT) are typical representatives of cellular Internet of things. These technologies are widely used in smart cities (e.g., meter reading), smart agriculture (e.g., collecting information such as temperature and humidity), and smart transportation (e.g., sharing a single vehicle).

In a communication system, two major technologies of MTC and NB-IoT are provided aiming at scenes such as low-rate and high-delay (such as meter reading and environment monitoring) in the service of the Internet of things in the related technology. Currently NB-IoT technologies can support a rate of several hundred K at maximum, and MTC can support a rate of several M at maximum. However, with the continuous development of internet of things services (e.g., monitoring, smart home, wearable device, and industrial sensor detection services), a rate of several tens to one hundred meters is generally required, and the requirement for time delay is relatively increased. Therefore, in a communication system, the MTC and NB-IoT technologies cannot meet the requirements of the current internet of things service. Meanwhile, in another aspect, the MTC and NB-IoT technologies are generally deployed in basements, fields, and other scenes where it is not easy to charge or change batteries, so the terminals associated with the MTC and NB-IoT technologies are limited by hardware, resulting in inferior coverage capability to general wireless communication terminals. And due to the influence of application environment, the power saving of the equipment is also the characteristics of MTC and NB-IoT. Based on this situation, it is proposed to redesign a new user equipment in the 5G NR to cover the requirement of the middle-end internet of things equipment. In the current 3GPP (3rd Generation Partnership Project) standardization, this new terminal type is called a Redcap terminal or simply NR-lite (reduced version new air interface).

The device working on the non-frequency spectrum needs to monitor the channel before sending data, and can send data only when the monitored channel is in an idle state. In the NR system, listening of a channel is performed in units of LBT subbands, where one LBT subband in the related art has a width of 20 MHz. And if the monitoring band is occupied in the LBT sub-band, no data is sent on the LBT sub-band. The BWP monitored by the terminal includes a plurality of LBT subbands, and if the terminal monitors that some LBT subbands are occupied (i.e. busy time), the terminal may perform data transceiving on other idle LBT subbands, thereby avoiding that the transceiving cannot be performed for a long time.

In a new generation of communication technology, Redcap terminals are introduced, which all operate in licensed spectrum. However, general industrial sensors and the like are mainly applied in the industrial field, and the industrial field mainly uses unlicensed spectrum, so that a Redcap terminal is required to work on the unlicensed spectrum. However, the bandwidth of a Redcap terminal is limited, for example, 20MHz can be monitored by a Redcap terminal in one FR1, that is, when the Redcap terminal operates in an unlicensed spectrum, only one channel can be monitored, that is, only one LBT sub-band can be monitored at a time. If the monitored LBT sub-band is occupied, data transmission and reception cannot be performed, and the Redcap terminal cannot communicate with the base station. The probability that a Redcap terminal will be blocked from communicating is greater than other terminals.

The monitoring method is provided based on the disclosure, and at least one LBT sub-band is configured for a terminal with limited bandwidth, so as to avoid the problem that the terminal cannot communicate with a network device when one LBT sub-band is blocked.

FIG. 2 is a flow chart illustrating a monitoring method according to an exemplary embodiment. As shown in fig. 2, the monitoring method is used in a terminal and includes the following steps.

In step S11, at least one LBT sub-band is determined.

Wherein, the LBT subband is used for carrying the PDCCH.

In the embodiment of the disclosure, the terminal determines at least one LBT subband configured for the terminal by the network device, where the LBT subband is a basic frequency resource unit for the terminal to perform channel monitoring. At least one LBT subband may enable terminals operating in unlicensed spectrum to monitor PDCCH. The terminal related to the embodiment of the present disclosure may be a Redcap terminal, and may also be other types of terminals.

Based on the monitoring method provided by the embodiment of the disclosure, the network device monitors the PDCCH for the plurality of LBT sub-bands configured for the terminal, so that the situation that the terminal working in the unlicensed spectrum is blocked in downlink communication can be avoided.

In some embodiments of the present disclosure, in a plurality of LBT subbands configured for a terminal by a network device, configuration parameters of each LBT subband may be the same, for example, subcarrier spacing is the same, and/or channel transmission parameters are the same. In the embodiment of the present disclosure, configuring the same configuration parameter for each LBT sub-band may enable the terminal to reduce the switching time of switching the monitored LBT sub-band when switching the monitored LBT sub-band.

In some embodiments of the present disclosure, in the disclosed embodiments, each LBT sub-band is configured with a set of physical resources (CORESET), and each CORESET may also be the same. If each identical CORESET is configured, the switching time for switching the monitoring LBT sub-band can be reduced.

And monitoring the LBT sub-bands one by one based on the first time length according to the sequence of monitoring the LBT sub-bands, circularly monitoring the LBT sub-bands, and monitoring the PDCCH on the LBT sub-bands.

For example, the network device may send the PDCCH on multiple (e.g., N, where N is a positive integer) LBT subbands according to a preset rule, and the terminal monitors the PDCCH in an N LBT polling monitoring manner according to an order of monitoring the LBT subbands. For example, the terminal monitors X PDCCH transmission occasions on the first LBT subband, then switches to the second LBT subband, monitors X PDCCH transmission occasions on the second LBT subband, and switches to the next LBT subband until switching to the nth LBT subband, and monitors the first LBT subband again after monitoring X PDCCH transmission occasions on the nth LBT subband.

And if the PDCCH corresponding to the terminal is not monitored on the default LBT sub-band and the time for monitoring the default LBT sub-band exceeds a first threshold value, determining to switch to other LBT sub-bands, and monitoring the PDCCH on the basis of the other LBT sub-bands.
