Title: Power-saving state switching method, terminal and base station

Description:
CROSS-REFERENCE TO RELATED APPLICATION 
     The present application claims a priority of the Chinese patent application No. 201810565820.3 filed in China on Jun. 4, 2018, which is incorporated herein by reference in its entirety. 
     TECHNICAL FIELD 
     The present disclosure relates to the field of mobile communication technology, in particular to a power-saving switching method, a terminal and a base station. 
     BACKGROUND 
     Along with the development of the wireless communication system, there are various terminal types and service types, and such requirements on a terminal as power-saving, network resource-saving and the satisfaction on various service types coexist. In order to reduce the power consumption of the terminal and ensure the service accessibility at the same time, a Wakeup Signal (WUS) has been introduced, and electricity consumption of the terminal is relatively low when the terminal monitors the WUS. Upon the receipt of a WUS from the terminal itself, the terminal is woken up by the WUS, and then a communication module (whose electricity consumption is relatively high) is enabled to receive a paging message, or receive a Physical Downlink Control Channel (PDCCH), or perform Radio Resource Management (RRM) measurement, or receive a synchronization message, thereby to reduce the power consumption of the terminal. 
       FIGS. 1 and 2  show the transmission of the WUS in a Radio Resource Control (RRC) idle state and an RRC connected state. When a User Equipment (UE) is in the idle state, it may enter a sleep state with extremely low electricity consumption. When downlink data is to be transmitted by a network side device to the UE, the WUS is transmitted to the UE. Upon the receipt of the WUS, the UE is woken up, and transmit data to, or receive data from, the network side device. After the transmission or reception of the data has been completed, the UE may enter the sleep state with extremely low electricity consumption again. Similarly, when the UE is in the RRC connected state and enters an inactive state, it may enter the sleep state with extremely low electricity consumption. When the UE needs to receive the downlink data, the network side device may transmit the WUS to the UE. Upon the receipt of the WUS, the UE is waked up and starts to transmit data to, or receive data from, the network side device. Through the above, it is able to reduce the power consumption of the UE. 
     Currently, the WUS is adopted in a Long Term Evolution (LTE) system-based Machine Type Communication (MTC) or Narrow Band Internet of Thing (NB-IOT) to further reduce the power consumption. However, in the current MTC or NB-IOT, in terms of power-saving configurations of the terminal, there are merely a power-saving configuration and a non-power-saving configuration, and the switching of power-saving modes in different power-saving configurations has not been involved yet. 
     SUMMARY 
     An object of the present disclosure is to provide a power-saving state switching method, a terminal and a base station, so as to configure different power consumption modes for the terminal, thereby to achieve the switching among different power-saving states. 
     In order to solve the above technical problem, the present disclosure provides in some embodiments a power-saving state switching method, including configuring, by a base station, a first power consumption mode of a terminal at a first time point, and transmitting configuration information of the first power consumption mode to the terminal. Two or more power consumption modes are supported by the terminal. 
     In addition, the present disclosure provides in some embodiments a power-saving state switching method, including configuring, by a terminal, a power consumption mode of the terminal as a first power consumption mode at a first time point.

       FIG. 3  is a block diagram of an applicable wireless communication system according to an embodiment of the present disclosure. The wireless communication system includes a terminal  31  and a base station  32 . The terminal  31  may also be called as a User Equipment (UE), and it may be a terminal side device such as a mobile phone, a tablet personal computer, a laptop computer, a Personal Digital Assistant (PDA), a Mobile Internet Device (MID), a wearable device or a vehicle-mounted device. It should be appreciated that, the specific type of the terminal  31  will not be particularly defined herein. The base station  32  may be a 5 th -Generation (5G) base station or a future base station (e.g., gNB, 5G NR NB), or a base station in the other communication system (e.g., eNB, Wireless Local Area Network (WLAN) access point, or another access point). The base station may be called as node B, evolved node B, access point, Base Transceiver Station (BTS), radio base station, radio transceiver, Basic Service Set (BSS), Extended service Set (ESS), node B, evolved node B (eNB), home node B, evolved home node B, WLAN access point, WiFi node or any other appropriate term in the field. The base station shall not be limited to a specific technical term, as long as a same technical effect is achieved. It should be appreciated that, merely the base station in the NR system is taken as an example in the embodiments of the present disclosure, but a specific type of the base station will not be particularly defined herein. 
     The base station  32  may communicate with the terminal  31  under the control of a base station controller. In various examples, the base station controller may be a part of a core network or some base stations. Some base stations may exchange control information or user data with the core network through backhaul. In some examples, some of the base stations may directly or indirectly communicate with each other through a backhaul link, and the backhaul link may be a wired or wireless communication link. The wireless communication system may support operations on a plurality of carriers (waveform signals at different frequencies). A multi-carrier transmitter may transmit modulated signals on the plurality of carriers simultaneously. For example, each communication link may be a multi-carrier signal modulated using various radio technologies. Each modulated signal may be transmitted on different carriers and may carry control information (e.g., reference signal or control channel), overhead information, data, etc. 
     The base station  32  may communicate with the terminal  31  in a wireless manner via an antenna of one or more access points. Each base station may provide a communication coverage at a corresponding coverage region. A coverage region for an access point may be a sector merely constituting a part of the coverage region. The wireless communication system may include various base stations (e.g., macro base station, micro base station, or pico base station). The base station may also use different radio technologies, e.g., cellular or WLAN radio access technology. The base station may be associated with same or different access network or operator deployments. The coverage regions of different base stations (including the coverage regions of the base stations of a same type or different types, the coverage regions using same or different radio technologies, or the coverage regions belonging to same or different access networks) may overlap each other. 
     A communication link in the wireless communication system may include an uplink for carrying uplink (UL) transmission (e.g., from the terminal  31  to the base station  32 ), or a terminal for carrying downlink (DL) transmission (e.g., from the base station  32  to the terminal  31 ). The UL transmission may also be called as reverse link transmission, and the DL transmission may also be called as forward link transmission. The downlink transmission may be performed using a licensed frequency band, a non-licensed frequency band or both. Similarly, the uplink transmission may be performed using the licensed frequency band, the non-licensed frequency band or both. 
     Based on the above description, the WUS and the relevant contents have not been discussed currently in the standard. In order to meet different power consumption requirements, the terminal needs to define different states. Hence, there is an urgent need to provide a corresponding scheme for switching or updating different states and performing configurations therefor. 
     An object of the present disclosure is to provide a power-saving state switching method, so as to define different power consumption modes of a terminal, and switch or update different power consumption modes. Through switching the power consumption mode, it is able for the terminal to meet the requirements on data reception as well as the power-saving requirements flexibly, thereby to further reduce the power consumption of the terminal. 
     To be specific, considering different power consumption requirements of the terminal, in the embodiments of the present disclosure, the terminal may be configured to be in different power consumption modes. The terminal (UE) may support two or more power consumption modes, which includes a normal power consumption mode and a low power consumption mode. Further, the low power consumption mode may include at least one power-saving mode and/or at least one sleep mode. Here, the power consumption of the terminal in the normal power consumption mode may be greater than that in the low power consumption mode, the power consumption of the terminal in the power-saving mode may be greater than that in the sleep mode, and the power consumption of the terminal in different power-saving modes or sleep modes may be different from each other. 
     To be specific, as compared with the normal power consumption mode, in the power-saving mode, the terminal may receive, e.g., a PDCCH, a Physical Downlink Shared Channel (PDSCH), a paging message, a CSI-RS, a CRS, an SSB or a PSS/SSS in a power-saving state through, e.g., reducing a bandwidth for detecting the PDCCH, reducing the quantity of times of PDCCH blind detection or PDCCH blind detection complexity, or reducing the quantity of reception antennae. For another example, the terminal may further be in the more power-saving sleep mode, and the sleep mode may include a light sleep mode and a deep sleep mode. 
     For ease of understanding, the power consumption modes probably involved in the embodiments of the present disclosure will be described hereinafter. 
     The respective power consumptions of the terminal in different power consumption modes may be different from each other. The power consumption may also be called as energy consumption, energy loss, or power loss. 
     The normal power consumption mode may be a mode where the terminal receives first data, e.g., the PDCCH, the SS, the PDSCH, the CSI-RS or the CRS, based on a first power consumption. Naturally, the terminal may also receive the other signals, which will not be further particularly defined herein. Correspondingly, the first power consumption may be a power consumption for receiving the PDCCH, the SS, the PDSCH, the CSI-RS, the CRS or the other signals, which will not be further particularly defined herein. 
     The power-saving mode may be a mode where the terminal receives second data, e.g., the WUS, the PDCCH, the SS, the PDSCH, the CSI-RS or the CRS, based on a second power consumption smaller than the first power consumption. Naturally, the terminal may also receive the other signals, which will not be further particularly defined herein. The second power consumption may be a power consumption for receiving the WUS, the PDCCH, the SS, the PDSCH, the CSI-RS, the CRS or the other signals, which will not be further particularly defined herein. 
     Here, the second power consumption may be smaller than the first power consumption. As compared with the normal power consumption mode, the terminal may reduce the bandwidth for the detection of the PDCCH or reduce the PDCCH blind detection complexity so as to enable the second power consumption to be smaller than the first power consumption, or reduce the quantity of reception times of the PDCCH, receive data through a part of reception antennae, or reduce the quantity of times of RRM measurement so as to reduce the power consumption. In the embodiments of the present disclosure, any other ways may also be adopted so as to reduce the power consumption, which will not be further particularly defined herein. 
     To be specific, the power-saving mode may include at least one of a first power-saving mode based on the reception of a WUS, a second power-saving mode where the bandwidth for the PDCCH detection and/or the quantity of times of PDCCH blind detection are reduced, a third power-saving mode where the quantity of times of RRM measurement is reduced, a fourth power-saving mode where the quantity of reception antennae is reduced, and a fifth power-saving mode where a transmission bandwidth and/or a reception bandwidth are adjusted. 
     The sleep mode may be a mode where the power consumption of the terminal is smaller than a predetermined power consumption threshold, or a mode where the terminal does not transmit or receive any data, or a mode where all or parts of components of the terminal are disabled. To be specific, the sleep mode may include at least one of a first sleep mode (also called as light sleep mode in the context) and a second sleep mode (also called as deep sleep mode in the context). 
     The first sleep mode may be a sleep mode where the terminal is in downlink synchronization with a serving base station, and the second sleep mode may be a sleep mode where the terminal does not need to be in downlink synchronization with the serving base station. 
     Alternatively, the first sleep mode may be a power consumption mode where the terminal is switched from the first sleep mode to the power-saving mode or a switching time of the normal power consumption mode is smaller than or equal to a first time threshold, and the second sleep mode may be a power consumption mode where the terminal is switched from the second sleep mode to the power-saving mode or the switching time of the normal power consumption mode is greater than or equal to a second time threshold which is greater than or equal to the first time threshold. Here, the first time threshold and the second time threshold may each be a positive real number greater than or equal to 0. 
     Alternatively, the first sleep mode may be a power consumption mode where the components of the terminal at a proportion smaller than or equal to a first proportion are disabled, and the second sleep mode may be a power consumption mode where the components of the terminal at a proportion greater than or equal to a second proportion, which is greater than or equal to the first proportion, are disabled. Here, the first proportion and the second proportion may each be a real number greater than 0 and smaller than or equal to 1. The components of the terminal may include, but not limited to, a radio frequency module, an intermediate frequency module and a baseband module. 
     Alternatively, the first sleep mode may be a power consumption mode where fine synchronization or time-frequency tracking needs to be performed after the terminal has been switched from the first sleep mode to the normal power consumption mode or the power-saving mode so as to receive Downlink Control Information (DCI) or service information, and the second sleep mode may be a power consumption mode where cell identification needs to be performed after the terminal has been switched from the second sleep mode to the normal power consumption mode or the power-saving mode so as to receive the DCI or the service information. The cell identification may include at least one of the following behaviors: rough synchronization and fine synchronization, reading a broadcast message, cell selection, and reading a system message. 
     For example, in the first sleep mode, the terminal may be switched from the first sleep mode to the power-saving mode within the first time threshold which is a positive real number greater than or equal to 0; or in the first sleep mode, the power consumption of the terminal may be smaller than or equal to a first power consumption threshold which is a real number; or in the first sleep mode, the terminal may be in downlink synchronization with the serving base station which is a base station providing the system message, a control message or data information to the terminal; or in the first sleep mode, at least one of the radio frequency module, the intermediate frequency module and the baseband module of the terminal is maintained in an operating mode; or the terminal may perform at least one of fine synchronization, the reception of the PDCCH and the reception of the PDSCH after the terminal has been woken up from the first sleep mode. The fine synchronization may include that the terminal receives a CRS for a synchronization operation, or the terminal receives a CSI-RS or a TRS for the synchronization operation, or the terminal performs a time-frequency tracking operation or other synchronization operations, which will not be further particularly defined herein. 
     In the second sleep mode, the terminal may be switched from the sleep mode to the power-saving mode within the second time threshold which is a positive real number greater than or equal to 0 and which is greater than or equal to the first power consumption threshold; or in the second sleep mode, the power consumption of the terminal may be smaller than or equal to a second power consumption threshold which is a real number and which is greater than or equal to the first power consumption threshold; or in the second sleep mode, the terminal may lose its downlink synchronization with the serving base station which is a base station providing the system message, the control message or the data information to the terminal; or in the second sleep mode, at least one of the radio frequency module, the intermediate frequency module and the baseband module of the terminal is maintained in a non-operating mode (i.e., in an off state); or the terminal may perform cell identification (which specifically includes at least one of synchronization, serving cell selection, reading the broadcast message, reading the system message update, fine synchronization, the reception of the PDCCH and the reception of the PDSCH) after the terminal has been woken up from the second sleep mode. The fine synchronization may include that the terminal receives the CRS for the synchronization operation, or the terminal receives the CSI-RS or the TRS for the synchronization operation, or the terminal performs the time-frequency tracking operation or some other synchronization operations, which will not be further particularly defined herein. 
     The power-saving state switching method will be described hereinafter in terms of a base station side and a terminal side. 
     As shown in  FIG. 4 , the present disclosure provides in some embodiments a power-saving state switching method for a base station side, which includes Step  41  of configuring, by a base station, a first power consumption mode of a terminal at a first time point, and transmitting, by a base station, configuration information of the first power consumption mode to the terminal. Two or more power consumption modes may be supported by the terminal. 
     Here, the base station may configure an initial power consumption mode of the terminal, or update a power consumption mode of the terminal. To be specific, the first power consumption mode may be any power consumption mode supported by the terminal, e.g., a normal power consumption mode, any power-saving mode or any sleep mode. 
     Through the above step, it is able for the base station in the embodiment of the present disclosure to configure the power consumption mode of the terminal, thereby to switch among different power consumption modes. 
     In Step  41 , when the first power consumption mode is the normal power consumption mode or the power-saving mode, the first power consumption mode may be configured in any one of the following ways. 
     1) The base station may configure the power consumption mode of the terminal in accordance with measurement information reported by the terminal. 
     The measurement information may include a measurement value of a target signal. The measurement value may be Reference Signal Received Power (RSRP), Reference Signal Received Quality (RSRQ), Reference signal Strength Indicator (RSSI), or Signal to Interference plus Noise Ratio (SINR). The target signal may be a WUS, an on-demand RS, a PSS/SSS, an SSB, a CSI-RS or a CRS. The on-demand RS may be an aperiodic signal, or a reference signal with a predefined transmission pattern, and it may be used for the rapid synchronization and/or RRM measurement of the terminal. For example, when the measurement value is greater than or equal to a first measurement value threshold, the base station may configure the normal power consumption mode for the terminal, and when the measurement value is smaller than the first measurement value threshold, the base station may configure a certain power-saving mode for the terminal. Naturally, in a possible embodiment of the present disclosure, when the measurement value is smaller than the first measurement value threshold, the base station may also configure the normal power consumption mode for the terminal. 
     2) The base station may configure the first power consumption mode of the terminal in accordance with capability information reported by the terminal. 
     To be specific, the capability information reported by the terminal may include a capability of a receiver of the terminal, e.g., a terminal capability of supporting the reception through a part of a bandwidth, or terminal capability of supporting to disable a part of radio frequency links, or a terminal capability of supporting to reduce the quantity of times of RRM measurement. Upon the receipt of the capability information, e.g., the terminal capability of supporting the reception through a part of the bandwidth, in a possible embodiment of the present disclosure, the base station may configure the first power consumption mode of the terminal as the normal power consumption mode, and when the terminal fails to support the reception through a part of the bandwidth, the base station may configure the first power consumption mode of the terminal as the power-saving mode. In a possible embodiment of the present disclosure, upon the receipt of the capability information, e.g., the terminal capability of supporting the reception through a part of the bandwidth, the base station may also configure the first power consumption mode of the terminal as the power-saving mode. 
     3) The base station may configure the first power consumption mode of the terminal in accordance with configuration information of a reception antenna of the terminal. 
     For example, when the terminal supports the operation through a part of the reception antennae, the base station may configure the first power consumption mode as the power-saving mode, and when the terminal fails to support the operation through a part of the reception antennae, the base station may configure the first power consumption mode of the terminal as the normal power consumption mode. In a possible embodiment of the present disclosure, when the terminal supports the operation through a part of the reception antennae, the base station may configure the first power consumption mode as the normal power consumption mode, and when the terminal fails to support the operation through a part of the reception antennae, the base station may configure the first power consumption mode of the terminal as the power-saving mode. 
     Furthermore, the base station may further configure a timer corresponding to the first power consumption mode, and the timer is used to notify the terminal to, when the timer reaches a predetermined time value, configure a power consumption mode of the terminal as another power consumption mode being different from the first power consumption mode. 
     4) The base station may randomly select the normal power consumption mode or one of the power-saving modes as the first power consumption mode. Here, preferably, the base station may uniformly and randomly select and configure the normal power consumption mode or a power consumption mode in the power-saving modes as the first power consumption mode. 
     5) The base station may configure the first power consumption mode of the terminal in accordance with a configuration history of the power consumption mode of the terminal. 
     6) The base station may configure the first power consumption mode of the terminal in accordance with a service type of the terminal. 
     As shown in the above configuration modes 4) to 6), the base station may configure the power consumption mode of the terminal through random selection, or in accordance with a previous power consumption mode, or in accordance with a historical power consumption mode of the terminal. For example, the base station may randomly select any of the historical power consumption modes of the terminal, or select a power consumption mode in the historical power consumption modes whose configuration proportion is greater than a first configuration threshold. Alternatively, the base station may configure the power consumption mode in accordance with the service type of the terminal. For a service where a real-time property and/or a data rate are highly demanded, e.g., a video service, a voice service or an on-line game, the base station may configure the first power consumption mode as the normal power consumption mode, and for a service where the real-time property and/or the data rate are not highly demanded, e.g., a http service or a ftp service, the base station may configure the power-saving mode for the terminal, or configure the normal power consumption mode for the terminal so as to improve the user experience. Naturally, other configuration methods may also be adopted, which will not be further particularly defined herein. 
     When the first power consumption mode is the sleep mode, in Step  41 , the first power consumption mode may be configured in any one of the following ways. 
     1) The base station may configure the first power consumption mode of the terminal in accordance with the capability information reported by the terminal. 
     Here, the base station may configure the first power consumption mode as one sleep mode supported by the terminal in accordance with the capability information reported by the terminal. Furthermore, the base station may configure a timer corresponding to the first power consumption mode, and the timer is used to, when the timer reaches a predetermined time value, configure the power consumption mode of the terminal as a sleep mode being different from the first power consumption mode. 
     2) The base station may randomly select and configure one sleep mode as the first power consumption mode. Here, preferably, the base station may uniformly and randomly select the power consumption mode in the sleep modes as the first power consumption mode. 
     3) The base station may configure the first power consumption mode of the terminal in accordance with a configuration history of the power consumption of the terminal. 
     4) The base station may configure the first power consumption mode of the terminal in accordance with a service type of the terminal. 
     As shown in the above configuration modes 2) to 4), the base station may configure the sleep mode of the terminal through random selection, or in accordance with a previous sleep mode, or in accordance with a historical sleep mode of the terminal. For example, the base station may randomly select any of the historical sleep configurations of the terminal, or select a sleep mode configuration in the historical sleep configurations of the terminal whose proportion is greater than a second configuration threshold. Alternatively, the base station may implement the configuration in accordance with the service type of the terminal. For a service where a real-time property and/or a data rate are highly demanded, e.g., a video service, a voice service or an on-line game service, the base station may configure the first sleep mode for the terminal, and for a service where the real-time property and/or the data rate are not highly demanded, e.g., a http service or a ftp service, the base station may configure the second sleep mode for the terminal, or configure the first sleep mode for the terminal so as to improve the user experience with respect to the service. Naturally, any other configuration methods may also be adopted, which will not be further particularly defined herein. 
     In Step  41 , the transmitting, by the base station, the configuration information of the first power consumption mode to the terminal may include: transmitting, by the base station, the configuration information of the first power consumption mode through Radio Resource Control (RRC) signaling and/or Medium Access Control (MAC) layer Control Element (CE) wherein the configuration mode is a static/semi-static configuration mode; or transmitting, by the base station, the configuration information of the first power consumption mode through DCI wherein the configuration mode is a dynamic configuration mode; or transmitting, by the base station, the configuration information of the first power consumption mode through a Radio Network Temporary Identity (RNTI)-scrambled PDCCH. Here, a correspondence between an RNTI and the power consumption mode may be pre-defined, and the power consumption mode corresponding to the RNTI may be notified to the terminal in accordance with the RNTI for scrambling the PDCCH. 
     Prior to Step  41 , the power-saving state switching method may further include Step  40  of configuring, by the base station, a second power consumption mode of the terminal at a second time point, and transmitting, by the base station, configuration information of the second power consumption mode to the terminal. 
     Here, the first time point and the second time point may each be a pre-agreed configuration time, or a static/semi-static configuration time, or a dynamic configuration time. The first and second power consumption modes may be supported by the terminal, and they may be the same, or different from each other. 
     Preferably, the second power consumption mode may be different from the first power consumption mode. For example, the second power consumption mode and the first power consumption mode may be two different modes in the normal power consumption mode and the power-saving modes, or two different modes in the sleep modes. Alternatively, the second power consumption mode may be one of the normal power consumption mode and the power-saving modes, and the first power consumption mode may be one of the sleep modes; or the second power consumption mode may be one of the sleep modes, and the first power consumption mode may be one of the normal power consumption mode and the power-saving modes. 
     Through the above Steps  40  and  41 , it is able to update the power-saving state of the terminal, e.g., configure the second power consumption mode for the terminal at the second time point, and configure the first power consumption mode for the terminal at the first time point. 
     In a possible embodiment of the present disclosure, when the second power consumption mode is the normal power consumption mode or the power-saving mode and the first power consumption mode is the normal power consumption mode or the power-saving mode, or when the second power consumption mode is the sleep mode and the first power consumption mode is the sleep mode, in Step  40 , the configuring the second power consumption mode of the terminal may include configuring, by the base station, a timer corresponding to the second power consumption mode, wherein the timer is used to notify the terminal to, when the timer reaches a predetermined time value, proceed to Step  41  of configuring the first power consumption mode of the terminal. 
     In a possible embodiment of the present disclosure, when the second power consumption mode is the normal power consumption mode or the power-saving mode and the first power consumption mode is the sleep mode, in Step  41 , the configuring the first power consumption mode of the terminal may further include: configuring an end time point for the transmission of downlink data for the terminal, the end time point being used to indicate a time point at which the terminal is switched to the first power consumption mode, and the end time point being represented by at least one of a boundary of a subframe, a boundary of a slot and a boundary of an Orthogonal Frequency Division Multiplexing (OFDM) symbol; or configuring a first sleep time point at which the terminal is switched to the first power consumption mode, the first sleep time point being the end time point for the transmission of the downlink data for the terminal, or a sum of the end time point and a predetermined first time window, or a sum of a transmission time point for the transmission of the downlink data for the terminal and a predetermined second time window, and the first sleep time point being represented by at least one of a boundary of a subframe, a boundary of a slot and a boundary of an OFDM symbol; or configuring a second sleep time point at which the terminal is switched to the first power consumption mode, the second sleep time point being a time point at which a timer for the transmission of the downlink data for the terminal has expired. 
     In the method according to the embodiments of the present disclosure, the base station may also transmit a power-saving signal for waking up the terminal in accordance with a predetermined transmission mode, and the predetermined transmission mode may include a periodic transmission mode and an aperiodic on-demand transmission mode. The predetermined transmission mode may be configured by the base station in accordance with the measurement information or capability information reported by the terminal, or determined by the terminal itself. 
     The power-saving state switching method at the base station side has been described hereinabove, and a power-saving state switching method at a terminal side will be described hereinafter. 
     As shown in  FIG. 5 , the present disclosure further provides in some embodiments a power-saving state switching method at a terminal side, which includes Step  51  of configuring, by a terminal, a power consumption mode of the terminal as a first power consumption mode at a first time point. 
     Here, two or more power consumption modes may be supported by the terminal. The types of the power consumption modes and the description thereof may refer to those mentioned hereinabove, and thus will not be repeated herein for conciseness. 
     In the embodiments of the present disclosure, when the first power consumption mode is the normal power consumption mode or the power-saving mode, in Step  51 , the power consumption mode of the terminal may be configured by the terminal in one of the following ways. 
     1) The terminal may receive configuration information of the first power consumption mode from a base station, and configure the power consumption mode of the terminal as the first power consumption mode in accordance with the configuration information. To be specific, the way of configuring the first power consumption mode by the base station may refer to that mentioned hereinabove, and thus will not be repeated herein 
     2) The terminal may determine the first power consumption mode in accordance with measurement value of a target signal, and configure the power consumption mode of the terminal as the first power consumption mode. 
     Here, the measurement information may include a measurement value of a target signal. The measurement value may be RSRP, RSRQ, RSSI or SINR, and the target signal may be a WUS, an on-demand RS, a PSS/SSS, an SSB, a CSI-RS or a CRS. The on-demand RS may be an aperiodic signal, or a reference signal with a predefined transmission pattern, and it may be used for the rapid synchronization and/or RRM measurement of the terminal. For example, when the measurement value is greater than or equal to a first measurement value threshold, the terminal may configure the power consumption mode of the terminal as the normal power consumption mode; and when the measurement value is smaller than the first measurement value threshold, the terminal may configure a certain power-saving mode. Naturally, in a possible embodiment of the present disclosure, when the measurement value is smaller than the first measurement value threshold, the terminal may also configure the power consumption mode of the terminal as the normal power consumption mode. 
     3) The terminal may determine the first power consumption mode in accordance with its own capability information, and configure the power consumption mode of the terminal as the first power consumption mode. 
     To be specific, the capability information of the terminal may include a capability of a receiver of the terminal, e.g., a capability of the terminal for supporting the reception through a part of a bandwidth, or a capability of the terminal for supporting to disable a part of radio frequency links, or a capability of the terminal for supporting to reduce the quantity of times of RRM measurement. In a possible embodiment of the present disclosure, when the terminal has the capability for supporting the reception through a part of the bandwidth, the terminal may determine the first power consumption mode as the normal power consumption mode, and when the terminal fails to support the reception through a part of the bandwidth, the terminal may determine the first power consumption mode as the power-saving mode. In a possible embodiment of the present disclosure, when the terminal has the capability for supporting the reception through a part of the bandwidth, the terminal may also determine the first power consumption mode as the power-saving mode. 
     4) The terminal may determine the first power consumption mode in accordance with configuration information of its own reception antennae, and configure the power consumption mode of the terminal as the first power consumption mode.

     Furthermore, the terminal may configure a timer corresponding to the first power consumption mode, wherein the timer is used to notify the terminal to, when the timer reaches a predetermined time value, configure a power consumption mode of the terminal as another power consumption mode being different from the first power consumption mode. 
     5) The terminal may randomly select and configure one of the normal power consumption mode and the power-saving modes as the first power consumption mode. Here, preferably, the terminal may uniformly and randomly select and configure a power consumption mode from the normal power consumption mode and the power-saving modes as the first power consumption mode. 
     6) The terminal may configure the first power consumption mode of the terminal in accordance with a configuration history of the power consumption mode of the terminal. 
     7) The terminal may configure the first power consumption mode of the terminal in accordance with a service type of the terminal. 
     As shown in the above configuration modes 4) to 6), the terminal may configure the power consumption mode of the terminal through random selection, or in accordance with a previous power consumption mode, or in accordance with a historical power consumption mode of the terminal. For example, the terminal may randomly select any of the historical power consumption modes of the terminal, or select and configure a power consumption mode in the historical power consumption modes whose configuration proportion is greater than a first configuration threshold. Alternatively, the base station may configure the power consumption mode in accordance with the service type of the terminal. For a service where a real-time property and/or a data rate are highly demanded, e.g., a video service, a voice service or an on-line game, the terminal may configure the first power consumption mode as the normal power consumption mode, and for a service where the real-time property and/or the data rate are not highly demanded, e.g., a http service or a ftp service, the terminal may configure the power-saving mode for the terminal, or configure the normal power consumption mode for the terminal so as to improve the user experience. Naturally, any other configuration methods may also be adopted, which will not be further particularly defined herein. 
     When the first power consumption mode is the sleep mode, in Step  51 , the first power consumption mode may be configured in any one of the following ways. 
     1) The terminal may configure the power consumption mode of the terminal as the first power consumption mode in accordance with configuration information of the first power consumption mode from the base station. To be specific, the way of configuring the first power consumption mode by the base station may refer to that mentioned hereinabove, and thus will not be particularly defined herein. 
     2) The terminal may determine the first power consumption mode in accordance with its own capability information, and configure the power consumption mode of the terminal as the first power consumption mode. 
     Furthermore, the terminal may configure a timer corresponding to the first power consumption mode, wherein the timer is used to notify the terminal to, when the timer reaches a predetermined time value, configure the power consumption mode of the terminal as a power consumption mode different from the first power consumption mode. 
     3) The terminal may determine the first power consumption mode in accordance with configuration information of its own reception antennae, and configure the power consumption mode of the terminal as the first power consumption mode. 
     4) The terminal may randomly select and configure one of the sleeping modes as the first power consumption mode. 
     5) The terminal may configure the first power consumption mode of the terminal in accordance with a configuration history of the power consumption mode of the terminal. 
     6) The terminal may configure the first power consumption mode of the terminal in accordance with a service type of the terminal. 
     As shown in the above configuration modes 4) to 6), the terminal may configure the sleep mode of the terminal through random selection, or in accordance with a previous sleep mode, or in accordance with a historical sleep mode of the terminal. For example, the terminal may randomly select any of the historical sleep modes of the terminal, or select a sleep mode in the historical sleep modes whose configuration proportion is greater than a second configuration threshold. Alternatively, the terminal may configure the sleep mode in accordance with the service type of the terminal. For a service where a real-time property and/or a data rate are highly demanded, e.g., a video service, a voice service or an on-line game service, the terminal may configure the first sleep mode for the terminal, and for a service where the real-time property and/or the data rate are not highly demanded, e.g., a http service or a ftp service, the terminal may configure the second sleep mode for the terminal, or configure the first sleep mode for the terminal so as to improve the user experience with respect to the service. Naturally, any other configuration methods may also be adopted, which will not be further particularly defined herein. 
     In Step  51 , the receiving, by the terminal, the configuration information of the first power consumption mode from the base station may include: receiving, by the terminal, the configuration information of the first power consumption mode from the base station through RRC signaling and/or an MAC layer CE; or receiving, by the terminal, the configuration information of the first power consumption mode from the base station through DCI; or receiving, by the terminal, the configuration information of the first power consumption mode from the base station through an RNTI-scrambled PDCCH.
