Title: Discontinuous reception (drx) parameter configuration method and device

Description:
CROSS-REFERENCE TO RELATED APPLICATIONS 
     This application is a continuation of International Application No. PCT/CN2018/102308 filed on Aug. 24, 2018, the disclosure of which is hereby incorporated by reference in its entirety. 
    
    
     TECHNICAL FIELD 
     The present disclosure relates to the field of communication, and in particular to discontinuous reception (DRX) parameter configuration methods and devices. 
     BACKGROUND 
     In related art, a packet-based data stream is usually bursty. If data transmission happens in a period of time, there may be no data transmission in a following long period of time. When there is no data transmission, power consumption can be reduced by stopping the reception of a physical downlink control channel (PDCCH), thereby increasing battery life. That is, a discontinuous reception (DRX) mechanism can be used. 
     In the DRX mechanism, a DRX cycle is configured for a terminal in a radio resource control (RRC) connected state. During an on duration (active) period of the DRX cycle, the terminal monitors and receives the PDCCH; and during an opportunity for DRX (sleep) period, the terminal does not receive the PDCCH so as to reduce the power consumption of the terminal, which is shown in  FIG. 1 . 
     In related art, a base station needs to send a scheduling message to control the terminal to enter a continuous active period for receiving data from the current DRX cycle. However, as the standardization relates to 5G, that is a new radio (NR) system, is ongoing under the 3rd generation partnership project (3GPP), the above process needs to be improved.

     DETAILED DESCRIPTION OF THE EMBODIMENTS 
     Exemplary embodiments will be described in detail below, and examples thereof are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, unless otherwise indicated, the same reference signs in different drawings represent the same or similar elements. The implementations described in the following exemplary embodiments do not represent all implementations consistent with the present disclosure. Rather, they are merely examples of devices and methods consistent with some aspects of the present disclosure as recited in the appended claims. 
     Terms used in the present disclosure are only for the purpose of describing exemplary embodiments, and are not intended to limit the present disclosure. For example, the terms “first,” “second,” “third,” etc. may be used in the present disclosure to describe various information, the information should not be limited to these terms. These terms are only used to distinguish the same type of information from each other. For example, without departing from the scope of the present disclosure, first information may be referred to as second information and, similarly, second information may also be referred as first information. Also for example, depending on the context, the word “if” as used herein can be interpreted as “upon” or “when” or “in response to a determination”. 
       FIG. 2  is a schematic diagram illustrating a configuration scenario of a discontinuous reception (DRX) parameter in related art. As shown in  FIG. 2 , when a terminal is in a first DRX cycle with a longer duration, the terminal monitors a PDCCH in an active period, e.g., an on duration period, and stops monitoring the PDCCH in a sleep period, e.g., an opportunity for DRX period. If the terminal receives a scheduling message sent by a base station during the active period of the first DRX cycle, the terminal may enter a continuous active period. 
     When the continuous active period ends, for example, a timer corresponding to the continuous active period expires or the terminal receives a media access control (MAC) control element (CE) sent by the base station, where the MAC CE instructs the terminal to stop receiving data. If the base station has previously configured the terminal with a second DRX cycle having a shorter period, the terminal enters the second DRX cycle; and if the second DRX cycle is not configured, the terminal enters the first DRX cycle. 
     After the terminal enters the second DRX cycle, the terminal starts a timer corresponding to the second DRX cycle configured by the base station for the terminal, and the terminal remains in the second DRX cycle during a validity period of the timer. When the timer expires, the terminal re-enters the first DRX cycle. 
     The above process in the related art does not involve a wake-up message. If the wake-up message is introduced, the DRX mechanism in the related art needs to be further improved. 
     Embodiments of the present disclosure provide a DRX parameter configuration method, which is applicable to a terminal.  FIG. 3  is a flowchart illustrating a DRX parameter configuration method according to some embodiments. Referring to  FIG. 3 , the method can include the following steps. 
     At step  101 , a wake-up parameter associated with a wake-up message configured by a base station for a terminal is received, where the wake-up message is configured to instruct the terminal to detect whether the wake-up message is received within each DRX cycle. 
     At step  102 , if it is determined that the wake-up message is received within the current DRX cycle, a continuous active period is entered at an end of the current DRX cycle. 
     At step  103 , a target DRX cycle is entered according to the wake-up parameter when the continuous active period ends, wherein the target DRX cycle is a first DRX cycle or a second DRX cycle, and a duration of the first DRX cycle is longer than a duration of the second DRX cycle. 
     In the embodiments, the terminal may receive a wake-up parameter associated with the wake-up message configured by the base station for the terminal. If the terminal determines that the wake-up message is received within the current DRX cycle, when the current DRX cycle ends, the terminal may enter the continuous active period. Further, the target DRX cycle can be entered according to the wake-up parameter when the continuous active period ends. In the embodiments, the wake-up message is used in the DRX mechanism, so that the terminal can respond faster when there is data to be transmitted, which can better save terminal resources and terminal power when there is no data to be transmitted. 
     In the step  101 , the base station can configure the wake-up parameter associated with the wake-up message for the terminal. The wake-up message allows the terminal to detect whether the wake-up message is received within each DRX cycle, and the wake-up message is detected with the current DRX cycle. When the current DRX cycle ends, the terminal enters the continuous active period for continuously receiving data. In an embodiment, the wake-up message may be a wake-up channel or a wake-up signal. 
     For example, the base station may configure a wake-up channel for the terminal, and the transmission of the wake-up channel includes one or more wake-up message bits, and may also include one or more message bits for other purposes. The bits are processed according to a physical layer processing flow, such as encoding and modulating according to a specified encoding method. After the terminal receives the channel, the terminal performs a demodulation/decoding operation to obtain the wake-up message. 
     In another example, the wake-up message may be a wake-up signal. For example, the base station configures one or more sequence signals for the terminal at a designated resource location. The sequence signals may be pre-defined and regulated by a protocol, and the sequence signal has a predetermined characteristic, such as strong autocorrelation. After the signal is received, the terminal determines that it has received the wake-up signal. 
     In some embodiments, the wake-up parameter associated with the wake-up message may include a first wake-up parameter and a second wake-up parameter. 
     The first wake-up parameter may be configured to instruct the terminal to count a total number of wake-up messages received in a plurality of designated subframes. For example, the first wake-up parameter may be a timer parameter that counts the total number of received wake-up messages in a target number of consecutive subframes/symbols starting from an initial subframe/symbol. If the starting subframe is a subframe/symbol whose index is n and the target number is m, the multiple subframes/symbols include m subframes/symbols which are from subframe/symbol n to subframe/symbol (n+m−1), such that the terminal counts the total number of the received wake-up messages in the m subframes/symbols. 
     The second wake-up parameter may be configured to instruct the terminal to determine whether the total number is lower than a predetermined threshold. For example, the second wake-up parameter may be a counter parameter, and the terminal increase the total number of wake-up messages by one every time it receives a wake-up message within the m subframes/symbols between subframe/symbol n and subframe/symbol (n+m−1). At last, the terminal determines whether the total number of wake-up messages received in the m subframes/symbols is lower than predetermined threshold L. 
     After the base station configures the wake-up parameter for the terminal, the base station can send to the terminal the wake-up parameter, which can be directly received by the terminal according to related technologies. 
     In the above embodiments, the wake-up parameter may include a first wake-up parameter and a second wake-up parameter, where the first wake-up parameter may be configured to instruct the terminal to count a total number of wake-up messages received in multiple designated subframes; and the second wake-up parameter may be configured to instruct the terminal to determine whether the total number is lower than a predetermined threshold. In the embodiments, the first wake-up parameter may also be configured to instruct the terminal to count the total number of received wake-up messages in multiple designated symbols. The terminal can, according to the above two parameters, count the total number of received wake-up messages in multiple subframes/symbols at designated locations and determine whether the total number reaches a predetermined threshold, to determine whether the terminal needs to enter the first DRX cycle or the second DRX cycle when the continuous active period ends, thereby offering a high availability. 
     In the embodiments, the base station may also configure other DRX parameters for the terminal according to related technologies. For example, other DRX parameters can also be sent to the terminal according to related technologies, such as a cycle duration of the first DRX cycle, a cycle duration of the second DRX cycle, a timer corresponding to the second DRX cycle. 
     In the step  102 , after the terminal receives the target DRX parameter, if the terminal determines that the wake-up message is received within the current DRX cycle, the terminal can enter the continuous active period for continuously receiving data according to the wake-up message. 
     In the embodiments, it can be detected that whether the wake-up message is received in a target subframe within the current DRX cycle, to determine whether the wake-up message is received within the current DRX cycle. 
     For example, a location of a target resource may be a location of a resource that is at the end of the current DRX cycle, and is about to enter the next DRX cycle, as shown in  FIG. 4 . If the wake-up message is detected in the target subframe, when the current DRX cycle ends, the terminal can directly enter the continuous active period. The number of target subframes is one or more. A target subframe may be determined in the following manners. 
     In a first manner, the target resource is configured by the base station and a subframe corresponding to the target resource is used by the terminal as the target subframe. In this way, the base station can configure a target resource for the terminal through preset signaling, such as RRC signaling. The target resource can be a time-frequency resource. The terminal uses the subframe corresponding to the target resource as the target subframe according to the target resource configured by the base station. 
     In a second manner, the target subframe is determined according to a pre-configuration. 
     In some embodiments, the target resource corresponding to the target subframe may be written into the protocol in advance. The terminal determines the target resource according to the pre-configuration in the underlying protocol, and uses the subframe corresponding to the target resource as the target subframe. 
     In some embodiments, the involved subframes can also be replaced with symbols, which are not limited in the present disclosure. 
     In the above embodiments, if the terminal receives the wake-up message at the location of the target subframe in the current DRX cycle, it determines that the wake-up message is received within the current DRX cycle. In some embodiments, the base station may configure the target resource for the terminal through preset signaling, and the terminal uses the subframe indicated by the target resource as the target subframe. The target subframe can also be determined according to the pre-configuration on the terminal. Through the above process, the terminal only needs to monitor whether the wake-up message is received on the target subframe in the current DRX cycle, which further saves terminal resources and terminal power. When the wake-up message is received, the terminal can enter the continuous active period in a timely manner to continuously receive data. 
     In the step  103 , the terminal may enter the target DRX cycle when the continuous active period ends. The target DRX cycle may be the first DRX cycle or the second DRX cycle, where the duration of the first DRX cycle is longer than that of the second DRX cycle. In some embodiments, a cycle duration of the first DRX cycle may be multiple times a cycle duration of the second DRX cycle. 
     In the embodiments, the terminal may determine that the continuous active period is ended when a preset timer corresponding to the continuous active period expires, or when receiving, from the base station, a MAC CE instructing the terminal to stop receiving data. 
     If it is determined that the total number of the wake-up message received by the terminal in multiple subframes at the designated locations is lower than the threshold according to the wake-up parameter, it means that the terminal has received fewer wake-up messages and the terminal may not need to perform a data transmission in a longer period of time. Therefore, the terminal may enter the first DRX cycle with a longer duration when the continuous active period ends. 
     If it is determined that the total number of the wake-up message received by the terminal in a plurality of subframes at the designated location reaches or exceeds the threshold according to the wake-up parameters, it means that the terminal has received more wake-up messages, and the terminal may need to perform the data transmission again in a short period of time. Therefore, the terminal may enter the second DRX cycle with a shorter period when the continuous active period ends. 
     In some embodiments, the involved subframes can also be replaced with symbols, which are not limited in the present disclosure. 
     In the above embodiments, if the total number of wake-up messages received by the terminal is lower than the threshold, the terminal may enter the first DRX cycle with a longer duration when the continuous active period ends; and if the total number of wake-up messages received by the terminal reaches or exceeds the threshold, the terminal may enter the second DRX cycle with a shorter duration when the continuous active period ends. Through the above process, when the terminal receives fewer wake-up messages, it can enter the first DRX cycle with a longer duration, thereby saving terminal power and terminal resources; and when the terminal receives more wake-up messages, it can enter the second DRX cycle with a shorter duration, so that the terminal can respond in a timely manner when there is data to be transmitted. 
       FIG. 5  is a flowchart of a DRX parameter configuration method according to an embodiment. As shown in  FIG. 5 , in addition to the steps  101 - 103  illustrated in  FIG. 3 , the method may further include the following steps. 
     At step  104 , if the first DRX cycle is entered when the continuous active period ends, a total number of received wake-up messages in the multiple subframes at designated locations within a currently entered first DRX cycle is recounted according to the first wake-up parameter. 
     In this step, if the terminal enters the first DRX cycle with a longer duration when the continuous active period ends, to respond in a timely manner when there is data to be transmitted, the terminal can recount the total number of the received wake-up messages in the multiple subframes at the designated locations within the currently entered first DRX cycle according to the first wake-up parameter. 
     In some embodiments, the involved subframes can also be replaced with symbols, which are not limited in the present disclosure. 
     At step  105 , if the total number is lower than the threshold, a new first DRX cycle is entered when the first DRX cycle ends. 
     At this step, if the total number of wake-up messages received within the first DRX cycle is relatively small and is lower than the threshold, the terminal may enter a new first DRX cycle with a longer duration when the first DRX cycle ends. 
     For example, the threshold value is 1, and the terminal does not receive the wake-up message in the first DRX cycle, that is, the total number of the wake-up message is 0, which is lower than the threshold, and the terminal can enter a new first DRX cycle with a longer duration when the current first DRX cycle ends. 
     At step  106 , if the total number reaches or exceeds the threshold, the continuous active period is entered again when the first DRX cycle ends. 
     At this step, if the total number reaches or exceeds the threshold, the terminal may enter the continuous activation period again when the current first DRX cycle ends. 
     For example, the threshold value is 1, and the terminal receives the wake-up messages in the first DRX cycle, and the total number of wake-up messages is also 1. When the threshold is reached, the terminal may re-enter the continuous active period for continuously receiving data when the current first DRX cycle ends. 
     In the above embodiments, if the terminal enters the first DRX cycle with a longer duration when the continuous active period ends, the terminal can recount the total number of received wake-up messages on the multiple subframes at designated location within the currently entered first DRX cycle according to the first wake-up parameter. In this way, the terminal may enter the first DRX cycle with a long duration, if the total number of wake-up messages received is lower than the preset threshold, the terminal can re-enter a new first DRX cycle when the first DRX cycle ends. If the total number of wake-up messages received reaches or exceeds the threshold, the terminal can quickly enter the continuous active period and receive data in a timely manner. 
       FIG. 6  is a flowchart of a DRX parameter configuration method according to an embodiment. As shown in  FIG. 6 , in addition to the steps  101 - 103  illustrated in  FIG. 3 , the method may further include the following step. 
     At step  107 , if no wake-up message is detected within the current DRX cycle, when the current DRX cycle ends, the first DRX cycle which remains a sleep state is entered, and the sleep state is a state in which the terminal does not monitor the PDCCH. 
     In this step, if the wake-up message is not detected within the current DRX cycle, at the end of the current DRX cycle, the terminal can enter the first DRX cycle in which the sleep state is always kept, and the sleep state is a state in which the terminal does not monitor the PDCCH. 
     That is, the terminal does not receive the wake-up message in the current DRX cycle, indicating that the terminal may not need to perform data transmission for a relatively long period of time. After the terminal enters the first DRX cycle, even if it is in the active period of the first DRX cycle, PDCCH blind detection may not be performed, thereby saving terminal resources and terminal power. 
     In the above embodiments, if the terminal does not receive the wake-up message in the current DRX cycle, when the current DRX cycle ends, the terminal can enter the first DRX cycle which remains the sleep state is, and the sleep state is a state in which the terminal does not monitor a state of the PDCCH. Through the above process, when the terminal does not receive the wake-up message in the current DRX cycle, it enters the first DRX cycle with a longer cycle duration, and puts itself in a long sleep state without PDCCH monitoring, thereby saving better terminal resources and terminal power. 
     Embodiments of the present disclosure also provide a configuration method for discontinuous reception of DRX parameters, which is applicable to a base station.  FIG. 7  is a flowchart illustrating a DRX parameter configuration method according to some embodiments. 
     At step  201 , a wake-up parameter associated with a wake-up message is configured for a terminal; 
     At step  202 , the wake-up parameter is sent to the terminal. 
     The wake-up message is configured to instruct the terminal to detect whether the wake-up message is received within each DRX cycle, and if it is determined that the wake-up message is received within a current DRX cycle, a continuous active period for continuously receiving data is entered at the end of the current DRX cycle. 
     The wake-up parameter is configured to instruct the terminal to enter a target DRX cycle when the continuous activation period ends. The target DRX cycle is a first DRX cycle or a second DRX cycle, and the duration of the first DRX cycle is longer than the duration of the second DRX cycle. 
     In the above embodiments, a wake-up parameter associated with a wake-up message may be configured by a base station for a terminal and the wake-up parameter may be sent to the terminal. The terminal detects whether the wake-up parameter is received within each DRX cycle, if the wake-up parameter is received within the current cycle, enters the continuous active period when the DRX cycle ends. Further, the terminal may enter the target DRX cycle when the continuous active period ends. In the above embodiment, the wake-up message is used in the DRX mechanism, and a wake-up parameter associated with the wake-up message is configured by the base station for the terminal, so that the terminal can respond faster when there is data to be transmitted, which can better save terminal resources and terminal power when there is no data to be transmitted. 
     In the step  201 , the base station can configure the wake-up parameter associated with the wake-up message for the terminal. The wake-up message allows the terminal to detect whether the wake-up message is received within each DRX cycle, and if it is determined that the wake-up message is received within the current DRX cycle, when the current DRX cycle ends, the terminal enters the continuous active period for continuously receiving data. In an embodiment, the wake-up message may be a wake-up channel or a wake-up signal. 
     In some embodiments, the wakeup parameter associated with the wakeup message may include a first wake-up parameter and a second wake-up parameter. 
     The first wake-up parameter may be configured to instruct the terminal to count a total number of wake-up messages received in a plurality of designated subframes. For example, the first wake-up parameter may be a timer parameter that counts the total number of received wake-up messages in a target number of consecutive subframes/symbols starting from an initial subframe/symbol. If the starting subframe is a subframe/symbol whose index is n and the target number is m, a plurality of subframes/symbols include m subframes/symbols which are from subframe/symbol n to subframe/symbol (n+m−1), such that the terminal counts the total number of the received wake-up messages in the m subframes/symbols. 
     The second wake-up parameter may be configured to instruct the terminal to determine whether the total number is lower than a predetermined threshold. For example, the second wake-up parameter may be a counter parameter, and the terminal increase the total number of wake-up messages by one every time it receives a wake-up message within the m subframes/symbols between subframe/symbol n and subframe/symbol (n+m−1). At last, the terminal determines whether the total number of wake-up messages received in the m subframes/symbols is lower than predetermined threshold L. 
     In the step  202 , the base station may send the configured wake-up parameter to the terminal through related technologies. In some embodiments, the base station may send the wake-up parameter to the terminal through a preset signaling, such as send the wake-up parameter through RRC signaling, or send the wake-up parameter through MAC CE. The present disclosure does not limit the sending method. 
     After receiving the wake-up parameters, the terminal side may detect whether a wake-up message is received within each DRX cycle. If it is determined that the wake-up message is received within the current DRX cycle, when the current DRX cycle ends, the terminal may enter continuous active period. Further, when the continuous active period ends, it needs to enter the target DRX cycle according to the wake-up parameter, that is, enter the first DRX cycle with a longer duration or the second DRX cycle with a shorter duration. 
     It should be noted that the subframes involved in the present disclosure can also be replaced with symbols, which are not limited in the present disclosure. 
       FIG. 8  is a flowchart of a DRX parameter configuration method according to some embodiments. As shown in  FIG. 8 , in addition to the steps  201  and  202  illustrated in  FIG. 7 , the method may further include the following steps. 
     At step  203 , a target resource is configured for the terminal; the target resource is a resource corresponding to a target subframe, and the target subframe is a subframe for the terminal to detect whether the wake-up message is received within each DRX cycle. [ 00100 ]In this step, a location of the target resource may be a location of a resource at the end of the current DRX cycle, and is about to enter the next DRX cycle, as shown in  FIG. 4 . If the wake-up message is detected in the target subframe, when the current DRX cycle ends, the terminal can directly enter the continuous active period. The number of target subframes is one or more. 
     The base station can configure the target resource corresponding to the target subframe in the current DRX cycle for the terminal. The target resource includes but are not limited to time-frequency resource. 
     At step  204 , the target resource is sent to the terminal through preset signaling. 
     At this step, the base station may configure a target resource for the terminal through preset signaling, for example, RRC signaling. 
     In the embodiment, the base station can configure the target resource for the terminal, and the terminal determines a target subframe according to the target resource. The terminal only needs to monitor whether the wake-up message is received on the target subframe of the current DRX cycle, which further saves terminal resources and terminal power. When the wake-up message is received, the terminal can enter the continuous active period in a timely manner to continuously receive data. 
       FIG. 9  is a flowchart of a DRX parameter configuration method according to some embodiments. The method may include the following steps. 
     At step  301 , a wake-up parameter associated with a wake-up message is configured by a base station for the terminal. 
     The wake-up message is configured to detect whether the wake-up message is received within each DRX cycle, and if it is determined that the wake-up message is received within the current DRX cycle, when the current DRX cycle ends, the terminal is controlled to enter a continuous active period for continuously receiving data; the target DRX cycle is the first DRX cycle or the second DRX cycle, and a cycle duration of the first DRX cycle is longer than a cycle duration of the second DRX cycle. 
     At step  302 , the wake-up parameter is sent by the base station to the terminal. 
     If the terminal determines that the wake-up message is received within the current DRX cycle, step  303  is performed, otherwise, step  309  is performed. 
     At step  303 , if it is determined that the wake-up message is received within the current DRX cycle, the terminal enters the continuous active period at the end of the current DRX cycle. 
     If the total number of the wake-up messages received is lower than a threshold, step  304  is performed; otherwise, step  308  is performed. 
     At step  304 , if the total number is lower than the threshold, the terminal enters the first DRX cycle when the continuous active period ends. 
     At step  305 , after entering the first DRX cycle, the terminal recounts the total number of the received wake-up messages in a plurality of subframes at a designated location within the currently entered first DRX cycle according to the first wake-up parameter. 
     At step  306 , if the total number is lower than the threshold, a new first DRX cycle is entered when the first DRX cycle ends. 
     At step  307 , if the total number reaches or exceeds the threshold, the continuous active period is entered again when the first DRX cycle ends. 
     At step  308 , if the total number reaches or exceeds the threshold, the terminal enters the second DRX cycle when the continuous active period ends. 
     At step  309 , if the wake-up message is not detected with the current DRX cycle, when the current DRX cycle ends, the terminal enters the first DRX cycle which remains the sleep state and the sleep state is a state in which the terminal does not monitor a state of the PDCCH. 
     In the embodiments, the wake-up message is used in the DRX mechanism, so that the terminal can respond faster when there is data to be transmitted, which can better save terminal resources and terminal power when there is no data to be transmitted. 
       FIGS. 10A and 10B  are schematic diagrams illustrating a configuration scenario of a DRX parameter according to some embodiments. 
     In an example, shown in  FIG. 10A , after receiving the target DRX parameter configured by the base station, the terminal detects whether the wake-up message is received on the target subframe within the current DRX cycle. The wake-up message may be a wake-up signal or a wake-up channel If the wake-up signal is not detected, the first DRX cycle with a longer duration is entered, and the PDCCH blind detection is not performed during the active period of the first DRX cycle. 
     If the wake-up message is detected by the terminal on the target subframe within the first DRX cycle, the terminal enters the continuous active period when the first DRX cycle ends, thereby continuously receiving data. 
     The terminal counts the total number of received wake-up messages in a plurality of subframes at designated location within the continuous active period. Assuming that the total number is 1, the threshold is 1, the total number has reached the threshold, and the terminal enters the second DRX cycle with a shorter duration when the continuous active period ends. 
     In another example, shown in  FIG. 10B , after receiving the target DRX parameter configured by the base station, the terminal detects whether a wake-up message is received on the target subframe within the current DRX cycle. The wake-up message may be a wake-up signal or a wake-up channel. If the wake-up signal is not detected, the first DRX cycle with a longer duration is entered. 
     If the terminal detects the wake-up message on the target subframe within the first DRX cycle, the terminal enters the continuous active period when the first DRX cycle ends, thereby continuously receiving data. 
     The terminal counts the total number of received wake-up messages in a plurality of subframes at designated location within the continuous active period. Assuming that the total number is 0, the threshold is 1, the total number is less than the threshold, and the terminal enters the first DRX cycle with a longer duration when the continuous active period ends. At the same time, according to the first wake-up parameter, the terminal recounts the total number of the received wake-up messages in a plurality of subframes at a designated location within the currently entered first DRX cycle according to the first wake-up parameter. 
     If the total number of the wake-up messages received within the first DRX cycle currently entered is 0 and is lower than the threshold 1, the terminal enters a new first DRX cycle when of the current first DRX cycle ends and remains sleep state within the new first DRX cycle, that is, the PDCCH blind detection is not performed during the active period of the first DRX cycle. 
     If the total number of wake-up messages received within the first DRX cycle currently entered is 1 which reaches the threshold 1, the terminal enters another continuous active period when the current first DRX cycle (not shown in  FIG. 10B ) ends.

     The technical solutions provided by the embodiments of the present disclosure may have the following beneficial effects. 
     In the embodiments, the terminal may receive a wake-up parameter associated with a wake-up message configured by the base station for the terminal. If the terminal determines that the wake-up message is received with a current DRX cycle, the terminal may enter a continuous active period when the current DRX cycle ends. Further, the target DRX cycle can be entered according to the wake-up parameter when the continuous active period ends. In the embodiments of the present disclosure, wake-up message is introduced to the DRX mechanism, so that the terminal can respond faster when there is data to be transmitted, and it can better save terminal resources and terminal power when there is no data to be transmitted. 
     In the embodiments, the wake-up parameter may include a first wake-up parameter and a second wake-up parameter, where the first wake-up parameter is configured to instruct the terminal to count a total number of wake-up messages received on multiple designated subframes; the second wake-up parameter may be used to instruct the terminal to determine whether the total number is lower than a predetermined threshold. The terminal can count the total number of received wake-up messages on multiple subframes/symbols at designated locations according to the above two parameters, and determine whether the total number reaches a predetermined threshold, so as to determine whether the terminal needs to enter the first DRX cycle or the second DRX cycle when the continuous active period ends, thereby offering a high availability. 
     In the embodiments, if the terminal receives the wake-up message at the location of the target subframe in the current DRX cycle, it determines that the wake-up message is received within the current DRX cycle. Optionally, the base station may configure the target resource for the terminal through preset signaling, and the terminal uses the subframe indicated by the target resource as the target subframe. The target subframe can also be determined according to the pre-configuration on the terminal. Through the above process, the terminal only needs to monitor whether the wake-up message is received on the target subframe in the current DRX cycle, which further saves terminal resources and terminal power. At the same time, when the wake-up message is received, it can enter the continuous active period in time to continuously receive data. 
     In the embodiments, if the total number of wake-up messages received by the terminal is lower than the threshold, when the continuous active period ends, the terminal may enter the first DRX cycle with a longer duration; if the total number of wake-up messages received by the terminal reaches or exceeds the threshold, when the continuous active period ends, the terminal may enter the second DRX cycle with a shorter duration. Through the above process, when the terminal receives less wake-up message, it can enter the first period with a longer period, thereby saving terminal power and terminal resources; when the terminal receives more wake-up information, enter the second period with a shorter period. DRX cycle, in order to respond quickly when there is data to be transmitted. 
     In the above embodiments, if the terminal enters the first DRX cycle with a longer duration when the continuous active period ends, the terminal can recount the total number of received wake-up messages on the multiple subframes at designated location within the currently entered first DRX cycle according to the first wake-up parameter. In this way, the terminal may enter the first DRX cycle with a long duration, if the total number of wake-up messages received is lower than the preset threshold, the terminal can re-enter a new first DRX cycle when the first DRX cycle ends. If the total number of wake-up messages received reaches or exceeds the threshold, the terminal can quickly enter the continuous active period and receive data in a timely manner. 
     In the above embodiments, if the terminal does not receive the wake-up message in the current DRX cycle, when the current DRX cycle ends, the terminal can enter the first DRX cycle which remains the sleep state is, and the sleep state is a state in which the terminal does not monitor a state of the PDCCH. Through the above process, when the terminal does not receive the wake-up message in the current DRX cycle, it enters the first DRX cycle with a longer cycle duration, and remain in a long period of sleep state without monitoring PDCCH, thereby saving better terminal resources and terminal power. 
     In the above embodiments, a wake-up parameter associated with a wake-up message may be configured by a base station for a terminal and the wake-up parameter may be sent to the terminal. The terminal detects whether the wake-up parameter is received within each DRX cycle, if the wake-up parameter is received within the current cycle, enters the continuous active period when the DRX cycle ends. Further, the terminal may enter the target DRX cycle according to the wake-up parameter when the continuous active period ends. In the above embodiments, a wake-up message is introduced to the DRX mechanism. A wake-up parameter associated with the wake-up message is configured by a base station, so that the terminal can respond faster when there is data to be transmitted, which can better save terminal resources and terminal power when there is no data to be transmitted.
