CROSS-REFERENCE TO RELATED APPLICATIONS 
     This application is a continuation application of International Application No. PCT/CN2020/123089 filed on Oct. 23, 2020, which claims priority to Chinese Patent Application No. 201911014316.5 filed on Oct. 23, 2019, which are incorporated herein by reference in their entireties. 
    
    
     TECHNICAL FIELD 
     Embodiments of the present disclosure relate to the field of communication technologies, and specifically, to a Radio Link Monitor (RLM) adjustment and/or Beam Failure Detection (BFD) adjustment method and device. 
     BACKGROUND 
     During energy saving of a terminal, Downlink Control Information (DCI) of a Physical Downlink Control Channel (PDCCH) indicates or introduces an advance indication signal (for example, a Wake Up Signal (WUS), Go To Sleep (GTS) or a pre-indication) to skip monitoring of a PDCCH in one or more subsequent Discontinuous Reception (DRX) cycles. That is, the terminal does not need to wake up and continue to monitor a PDCCH during DRX on Duration. 
     However, to ensure the reliability of a radio link and/or beam, the terminal needs to perform RLM and/or BFD periodically according to certain requirements, for example, wake up to perform RLM and/or BFD in each DRX cycle or several DRX cycles. In this case, even if there is DCI or an advance indication signal indicating that the terminal does not need to monitor a PDCCH, the terminal still needs to wake up to perform RLM and/or BFD, which is not conducive to power saving of the terminal.

     DETAILED DESCRIPTION 
     For better understanding of the embodiments of the present disclosure, several technical points are described below: 
     1. About an RLM and Radio Link Failure (RLF) Functions 
     A Radio Link Monitor (RLM) function is provided in both a Long Term Evolution (LTE) system and a New Radio (NR) system. 
     In the RLM function in LTE, a terminal (for example, User Equipment (UE)) measures a PDCCH part Cell Reference Signal (CRS) and a Signal to Interference plus Noise Ratio (SINR) to implement monitoring of a radio link. 
     When the measured PDCCH part CRS is less than a particular threshold, it is determined that the radio link is Out-Of-Sync (OOS). A physical layer notifies a higher layer (for example, a Radio Resource Control (RRC) layer) of an out-of-sync indication. If the RRC layer has N consecutive out-of-sync indications, the UE starts a Timer T 1 . 
     When the measured PDCCH part CRS is greater than a particular threshold, it is determined that the radio link is In-Sync (IS). The physical layer notifies the higher layer (for example, the RRC layer) of an in-sync indication. If the RRC layer has M consecutive in-sync indications, the UE stops the running of the Timer T 1 . 
     If the running of the Timer T 1  expires, the UE determines that the radio link fails. 
     Quantities (N and M) of times of counts of “out-of-sync” and “in-sync” are configured by a network, and when the quantities of times are reached, the running duration of the Timer T 1  is also configurable by a network side. 
     2. About BFD. 
     In the future 5 th  generation (5G) mobile communications system, high-frequency communication and a large-scale antenna technology are introduced to achieve the objective of a 20-Gbps downlink transmission rate and a 10-Gbps uplink transmission rate. The high-frequency communication can provide wider system bandwidth and smaller antenna size, which is more conducive for large-scale antenna deployment in base stations (for example, Next Generation NodeB (gNB)) and UEs. The high-frequency communication has the disadvantages of larger path loss, high susceptibility to interference, and a more vulnerable link, while the large-scale antenna technology can provide a larger antenna gain. Therefore, the combination of high-frequency communication and a large-scale antenna is an inevitable trend of future 5G mobile communications systems. However, the use of the large-scale antenna technology cannot solve all the problems of the high-frequency communication, for example, the vulnerability of a link. When blocking is encountered in the high-frequency communication, a beam failure recovery mechanism can quickly switch between beams, to switch a communication link from a poor beam to a better beam to avoid a wireless link failure, thereby effectively improving the robustness of the link. 
     In the 3 rd  Generation Partnership Project (3GPP) Radio Access Network (RAN)1 #88Bis, the following conclusions are reached about a UE beam failure recovery mechanism:
         UE beam failure recovery mechanism includes the following aspects:   Beam failure detection;   New candidate beam identification;   Beam failure recovery request transmission; and   UE monitors gNB response for beam failure recovery request.       

       FIG. 1  shows a possible beam failure recovery method of UE. New candidate beam identification may be performed before beam failure detection or after beam failure detection. 
     3. Determination of a Beam Failure: 
     During current beam failure detection, a physical layer determines that a particular condition (for example, all beam received signals are less than a threshold) is satisfied and then indicates a beam failure instance to a Media Access Control (MAC) layer. The MAC layer counts a quantity of beam failure instances periodically indicated by the physical layer to determine whether a beam fails. A specific counting manner may be as follows: 
     1. When there are N consecutive or non-consecutive instances, it is determined that a beam fails. 
     2. If one instance is received within one timer, a counter is increased by 1. The timer is started or restarted once an instance is received. If no instance is received before the timer expires, the counter is reset. When the counter reaches a preset quantity of times, it is determined that a beam fails. 
     The current technical discussion does not address RLM measurement relaxation and/or BFD detection relaxation. When a PDCCH or an advance indication signal indicates that the PDCCH is not to be monitored, a terminal still needs to wake up from a DRX off state to perform RLM and/or BFD, and as a result the objective of power saving fails to be achieved. 
     With the development of smart terminals, nowadays there are more and more sensors on smart terminals and the sensors are becoming more and more intelligent. In many cases and scenarios, a terminal can precisely know whether the terminal is in a mobile state as well as a movement speed and related movement information. In addition, when carrying more sensors, a smart terminal can obtain status or environment information or coverage information of UE. Based on such information, more control optimization can be performed on the behavior of the UE. For example, RLM measurement relaxation and/or BFD detection relaxation is performed in a scenario in which the terminal is in an adequate channel condition or is at the center of a cell or the terminal is not moving fast. The objective of power saving can be effectively achieved. 
     In addition, the terms “include” and any variant thereof in the description and claims of the present application are intended to cover the non-exclusive inclusion. For example, a process, method, system, product, or device that includes a series of steps or units is not necessarily limited to those expressly listed steps or units, but may include other steps or units not expressly listed or inherent to such a process, method, product, or device. In addition, “and/or” used in the description and claims represents at least one of connected objects. For example, A and/or B represents the following three cases: Only A exists, only B exists, and both A and B exist. 
     In addition, in the embodiments of the present disclosure, the word “exemplary” or “for example” is used to represent giving an example, an illustration, or a description. Any embodiment or design scheme described as an “exemplary” or “for example” in the embodiments of the present disclosure should not be explained as being more optional or having more advantages than another embodiment or design scheme. Exactly, use of the word “example” or “for example” or the like is intended to present a related concept in a specific manner.

An RLM and/or BFD adjustment method and device provided in the embodiments of the present disclosure are applicable to a wireless communications system.  FIG. 2  is a schematic architectural diagram of a wireless communications system according to an embodiment of the present disclosure. As shown in  FIG. 2 , the wireless communications system may include a network device  20  and a terminal  21 . The terminal  21  may be denoted as UE  21 .

In an actual application, connections between the foregoing devices may be wireless connections. For convenience of visually showing a connection relationship between the devices, solid lines are used for illustration in  FIG. 2 . 
     The network device  20  provided in the embodiments of the present disclosure may be a base station. The base station may be a conventional base station, or may be an evolved base station (eNB), or may be a device such as a network device (for example, a next generation base station (gNB) or a transmission and reception point (TRP)) in a 5G system.

     Referring to  FIG. 3 , the embodiments of the present disclosure provide an RLM and/or BFD adjustment method. The method may be performed by a terminal, and includes step  301  and step  302 . 
     Step  301 : Obtain first information and/or parameters configured by a network side, the first information including one or more of the following: a measurement result of the terminal, status information of the terminal, environment information, and network coverage information. 
     Optionally, the parameters configured by the network side are configured in at least one manner in the following: (1) the network side configures the corresponding parameters for each terminal; (2) the network side configures the corresponding parameters for each cell; (3) the network side configures the corresponding parameters for each frequency, carrier, band or bandwidth part; (4) the network side configures the corresponding parameters for each frequency, carrier, band or bandwidth part of each terminal; and (5) the network side configures the corresponding parameters for each beam. 
     Optionally, a sensor in the related art of the terminal is used to obtain the status information, the environment information, and/or the network coverage information. The status information may represent a movement status of the terminal. The environment information may represent a status of an environment in which the terminal is located. The network coverage information may represent a status of network coverage at the position of the terminal. 
     Step  302 : Determine, according to the first information and/or the parameters configured by the network side, whether to perform RLM measurement and/or BFD detection adjustment. 
     In some implementations, the terminal receives the parameters configured by the network side, and determines, according to the measurement result and/or the parameters configured by the network side, whether to perform the RLM measurement and/or BFD detection adjustment. 
     For example, the parameters configured by the network side are received by using a Radio Resource Control (RRC) message or a broadcast message. 
     The measurement result may be a result obtained by measuring a cell and/or a beam, and includes one or more of the following: a Reference Signal Receiving Power (RSRP); a Reference Signal Receiving Quality (RSRQ); a signal-to-noise and interference ratio (SINR); and a Channel Quality Indicator (CQI). 
     The measuring a beam may include: measuring a Synchronization Signal block (SSB), a CSI Reference Signal (CSI-RS), a Demodulation Reference Signal (DMRS) or another reference signal. 
     The measuring a cell includes measuring a current cell and/or a neighboring cell. 
     The parameters configured by the network side may be configured in a manner in the following: 
     (1) The network side configures the corresponding parameters for each terminal (Per-UE), that is, a network configures a separate adjustment determination parameter for each UE. 
     (2) The network side configures the corresponding parameters for each cell (Per-cell), that is, adjustment determination parameters configured by the network in the range of one cell are consistent. The terminal applies the parameter in the range of a cell. 
     (3) The network side configures the corresponding parameters for each frequency, carrier, band or bandwidth part (Per-frequency/carrier/band/BWP), that is, adjustment determination parameters configured by the network in the range of one frequency/carrier/band/BWP are consistent. 
     (4) The network side configures the corresponding parameters for each frequency, carrier, band or bandwidth part of each terminal (Per-UE per-frequency/carrier/band/BWP), that is, adjustment determination parameters configured by the network for each UE in the range of one frequency/carrier/band/BWP are consistent. 
     (5) The network side configures the corresponding parameters for each beam (Per-Beam), that is, applies the parameters to measurement corresponding to the beam. 
     Further, before receiving the parameters configured by the network side, the terminal may send a request message to the network side. 
     The request message is used for requesting the network side to configure the parameters configured by the network side, or the request message indicates that the terminal needs to perform RLM measurement relaxation, RLM measurement enhancement, normal RLM measurement, BFD detection relaxation, BFD detection enhancement or normal BFD detection. 
     In some implementations, the determining, according to the first information and the parameters configured by the network side, whether to perform RLM measurement adjustment and/or BFD detection adjustment includes:

     (4) determining, according to a measurement result of a current cell, a measurement result of a neighboring cell, and a preset threshold, whether to perform the RLM measurement adjustment and/or BFD detection adjustment;

     for example, if the measurement result of the current cell and the preset threshold satisfy an eighth condition, and/or if the measurement result of the neighboring cell and the preset threshold satisfy a ninth condition, performing RLM measurement enhancement and/or BFD detection enhancement.
