The present disclosure relates to the field of communication technology, and more particularly to a communication method and apparatus based on a measurement relaxation mechanism, and a storage medium.
In a mobile communication system, movement of a terminal causes channel conditions around the terminal to change constantly. In order to support the mobility of the terminal and obtain the current cell channel condition of the terminal timely, a network will configure a radio resource management (RRM) measurement for the terminal to measure a signal quality of a current serving cell and neighboring cells of the terminal. However, excessive RRM measurements will increase power consumption of the terminal and reduce battery life.

The following description refers to the accompanying drawings in which the same numbers in different drawings represent the same or similar elements unless otherwise represented. The implementations set forth in the following description of illustrative embodiments do not represent all implementations consistent with the present disclosure. Instead, they are merely examples of devices and methods consistent with some aspects of the present disclosure.
In some embodiments, a new radio (NR) introduces an RRM measurement relaxation mechanism for the terminal in an idle state. That is, when the terminal is at a low mobility or/and a non-cell edge, it is considered that the terminal is unlikely to suffer from cell reselection/handover, so the terminal is allowed to perform an RRM measurement relaxation to a certain extent, such as extending a measurement period or stopping a measurement on the neighboring cells, to reduce the power consumption.
For a terminal to perform the RRM measurement relaxation, the terminal needs to have a terminal capability for performing the RRM measurement relaxation mechanism and has been configured with an RRM measurement relaxation criterion. For a terminal, the RRM measurement relaxation may be performed in the idle state, but the measurement relaxation has certain risks, and an improper relaxation will cause the terminal to be unable to obtain the signal quality of the neighboring cells timely, affecting the performance of the cell reselection/handover, and reducing user experiences. Therefore, it is a hot research topic to provide a new communication method based on the measurement relaxation mechanism to enable the terminal to flexibly support the RRM measurement relaxation and to have more flexibility.
A communication method based on a measurement relaxation mechanism according to embodiments of the present disclosure may be applied to a wireless communication system shown in

The network may be classified into a 2nd generation (2G) network, a 3G network, a 4G network, or a future evolution network, such as a 5G network, which may also be referred to as a new radio (NR) network, according to the capacity, rate, delay and other factors of different networks. For ease of description, the wireless communication network will be sometimes abbreviated as a network in the present disclosure.
Further, the network device involved in the present disclosure may also be referred to as a radio access network device. The radio access network device may be a base station, an evolved node B, a home base station, an access point (AP) in a wireless fidelity (WIFI) system, a wireless relay node, a wireless backhaul node, a transmission point (TP), a transmission and reception point (TRP) or the like, or may also be a gNB in an NR system, or may also be a component or a part of a device that constitutes a base station, etc. The network device may also be a vehicle-mounted device when it is used in a vehicle to everything (V2X) communication system.

In addition, the terminal device may also be a vehicle-mounted device when it is used in a vehicle to everything (V2X) communication system. It is to be understood that the specific technology and specific device form adopted by the terminal are not limited in embodiments of the present disclosure.
In order to reduce the power consumption of the terminal, an RRM measurement relaxation mechanism is introduced for terminals in an idle state. In the measurement relaxation mechanism, communications are performed mainly based on a measurement relaxation criterion. The measurement relaxation criterion includes a non-cell edge criterion, a low mobility criterion, and a stationary criterion.
The low mobility criterion refers to that if a difference between a reference received signal strength (SrslevRef) and a signal strength (Srslev) of a current serving cell of the terminal is less than a preset threshold value (SSearchDeltaP) within a certain time (TSearchDeltaP), indicating that a signal of the terminal does not change greatly, it is considered that the terminal is currently in a low mobility state. The parameters SSearchDeltaP and TSearchDeltaP are provided by the network, and formulas are specified by a protocol.
The non-cell edge criterion mainly refers to that: if a received signal strength (Srxlev) of the current serving cell of the terminal is greater than a preset threshold value (SsearchThresholdP), and a received signal quality (Squal) (if configured) is greater than a preset threshold value (SsearchThresholdQ), it is considered that the terminal is not at an edge of the cell. SsearchThresholdP and SsearchThresholdQ are configured by the network, and the formulas are specified by a protocol.
The stationary criterion mainly refers to that: if a difference between a signal reception strength (Srxlev) of the current serving cell of the terminal and a reference signal reception strength (SrxlevRef) is less than a preset threshold value (SSearchDeltaP_stationary) within a certain time (TSearchDeltaP_stationary), and a number of beam switching times of the terminal (if configured) is less than a threshold value (Nbeam_switching) within the certain time, it is considered that the signal of the terminal does not change greatly, and no beam switching occurs, and the terminal is considered to be in a stationary state. The parameters TSearchDeltaP_stationary, SSearchDeltaP_stationary, and Nbeam_switching are provided by the network, and the formulas are specified by a protocol.
In 3GPP, it is considered to further research the RRM measurement relaxation under a reduced-capability (RedCap) device type, and it is considered to introduce a more advanced measurement relaxation criterion-stationary criterion, and introduce the RRM measurement relaxation into a connected state. Furthermore, after the design of the RRM measurement relaxation of the RedCap device is completed, it is highly likely to be introduced for use in an enhanced mobile broadband (eMBB) device (a conventional terminal, such as a mobile phone) in an NR.
However, for a terminal, the above three criteria may be used to perform the RRM measurement relaxation, but the measurement relaxation has certain risks, and an improper relaxation will cause the terminal to be unable to obtain the signal quality of the neighboring cells timely, affecting the performance of the cell reselection/handover, and reducing user experiences. Furthermore, whether to perform the RRM measurement relaxation depends more on implementations of terminals, for example, some terminals want to turn on a power saving mode, while some terminals care about the maximization of the performance without considering the power consumption. To sum up, whether the terminal performs the measurement relaxation depends on various implementations.
In view of the above, the present disclosure provides a new communication method and apparatus based on a measurement relaxation mechanism. In the method, a terminal capability for the RRM measurement relaxation (hereinafter referred to as the measurement relaxation capability) is introduced, so that the terminal may flexibly support the RRM measurement relaxation and have more flexibility.

A terminal that supports the measurement relaxation uses parameters corresponding to the measurement relaxation capability in the system broadcast message to perform a decision of a corresponding RRM measurement relaxation criterion. When the measurement relaxation criterion is satisfied, the terminal reports this state to the network device. A terminal in the connected state or a terminal in the non-connected state may obtain the measurement relaxation parameters provided by the network device through the system broadcast message. That is, the terminal in the connected state or the terminal in the non-connected state may obtain the measurement relaxation parameters configured by the network device based on the system broadcast message broadcasted by the network device, and determine the measurement relaxation parameters corresponding to the measurement relaxation capacity information supported by itself from the measurement relaxation parameters configured by the network device.

In embodiments of the present disclosure, for the case where the terminal supports the measurement relaxation criterion and is in the connected state, and there is no need to report the measurement relaxation capability information to the network device, the terminal may also use the RRM measurement relaxation parameters provided by the network to perform the RRM measurement relaxation.
In an example, the network device provides the measurement relaxation parameters through a system broadcast message. The terminal that supports the measurement relaxation uses parameters corresponding to the measurement relaxation capability in the system broadcast message to perform a decision of a corresponding RRM measurement relaxation criterion. When the measurement relaxation criterion is satisfied, the terminal reports this state (the RRM measurement relaxation criterion performed) to the network device.
In another example, the network device provides the measurement relaxation parameters through an RRC dedicated signaling, and the terminal that supports the measurement relaxation obtains the measurement relaxation parameters and uses corresponding measurement relaxation parameters to perform the RRM measurement relaxation.

In embodiments of the present disclosure, in case that the conditions for performing the measurement relaxation are not met (either it is determined by the terminal after performing an RRM measurement, or the network does not configure the measurement relaxation parameters), the UE will not perform the RRM measurement relaxation.
In embodiments of the present disclosure, the terminal may obtain the RRM measurement relaxation parameters in two manners:
1. an RRC dedicated signaling notification manner; and
2. a system message broadcast notification manner.
The RRC dedicated signaling notification manner is unique to terminals in the connected state, and a certain terminal may be notified with this manner. For the system message broadcast notification manner, the network device will not notify a certain terminal, but notify all terminals in a cell to provide parameters for the use of the RRM measurement relaxation.
Furthermore, after the terminal determines the measurement relaxation capability information, there are two options:
1. reporting the measurement relaxation capability information; and
2. no need to report the measurement relaxation capability information, and the terminal determines whether to use the measurement relaxation mechanism autonomously.
A terminal in the non-connected state cannot report the measurement relaxation capability information to the network device, so it can only adopt the option of no need to report the measurement relaxation capability information. A terminal in the connected state may use any of the above two options to indicate the capability.
It may be understood that in embodiments of the present disclosure, for a terminal in the connected state, it may report the measurement relaxation capability information, and interact with the network device to determine whether to perform the measurement relaxation.
Based on the same concept, embodiments of the present disclosure also provide a communication method based on a measurement relaxation mechanism performed by a network device.
In step S51, measurement relaxation capability information reported by a terminal is obtained. The measurement relaxation capability information is configured to indicate a radio resource management (RRM) measurement relaxation capability that the terminal supports to use in a connected state.
In an implementation, the measurement relaxation capability may also be understood as whether a measurement relaxation criterion is supported, that is, the measurement relaxation capability information determined by the terminal may be configured to indicate whether the terminal supports an RRM measurement relaxation criterion in a non-connected state or a connected state.
In embodiments of the present disclosure, the measurement relaxation capability of the terminal may include, but is not limited to, following types of measurement relaxation criterion: supporting all measurement relaxation criteria; supporting a non-cell edge criterion; supporting a low mobility criterion; supporting a stationary criterion; supporting a non-cell edge criterion and/or supporting a low mobility criterion; supporting a non-cell edge criterion and/or supporting a stationary criterion; supporting a non-cell edge criterion, and/or supporting a low mobility criterion and/or a stationary criterion; or not supporting any measurement relaxation criterion.
Further, the network device may adopt at least one of the following manners to obtain the measurement relaxation capability information reported by the terminal:
manner 1: obtaining the measurement relaxation capability information reported by the terminal based on a terminal radio capability message; or
manner 2: obtaining the measurement relaxation capability information reported by the terminal based on initialization assistance information; or
manner 3: obtaining the measurement relaxation capability information reported by the terminal based on message 5 in an RRC connection setup process or an RRC connection resume process; or
manner 4: obtaining the measurement relaxation capability information reported by the terminal based on message 3 in an RRC connection setup process or an RRC connection resume process.
In embodiments of the present disclosure, the network device may send measurement relaxation parameters, so that the terminal uses RRM measurement relaxation parameters provided by the network device to perform an RRM measurement relaxation.
The network device may send the measurement relaxation parameters corresponding to the measurement relaxation capability information configured by the network device based on an RRC dedicated signaling. The network device may also send the measurement relaxation parameters configured by the network device via a system broadcast message broadcasted by the network device.
It may be understood that measurement relaxation criterion information configured and sent by the network device is similar to an implementation process where the terminal performs the measurement relaxation mechanism in the connected state as described in the above embodiments, and reference may be made to the relevant descriptions in the above embodiments for details, which will not be elaborated here.
It may be further understood that the communication method based on the measurement relaxation mechanism according to embodiments of the present disclosure may be applicable to a scenario where the terminal and the network device interact to perform the communication method based on the measurement relaxation mechanism. For the functions implemented by the terminal and the network device involved in the specific implementation process, reference may be made to the relevant descriptions involved in the above embodiments, which will not be described in detail here.
It should be noted that those skilled in the art may understand that the various implementations/embodiments mentioned above in embodiments of the present disclosure may be used in conjunction with the foregoing embodiments or may be used independently. Whether used alone or in conjunction with the foregoing embodiments, the implementation principles are similar. In implementations of the present disclosure, some embodiments are described in terms of implementations used together. Of course, those skilled in the art may understand that such illustrations do not limit embodiments of the present disclosure.
Based on the same concept, embodiments of the present disclosure also provide a communication apparatus based on a measurement relaxation mechanism.
It may be understood that, in order to implement the above-mentioned functions, the communication apparatus based on the measurement relaxation mechanism according to embodiments of the present disclosure includes corresponding hardware structures and/or software modules for performing various functions. Embodiments of the present disclosure may be implemented in a form of hardware or a combination of hardware and computer software in combination with units and algorithm steps of each example disclosed in embodiments of the present disclosure. Whether a function is performed by hardware or by hardware driven by computer software depends on specific applications and design constraints of the technical solution. Those skilled in the art may use different methods to implement the described functions for each specific application, but such an implementation should not be regarded as extending beyond the scope of the technical solutions of embodiments of the present disclosure.
