     BACKGROUND 
     Energy saving of terminals has always been an import research topic in the technical field of communication. Discontinuous reception (DRX) mechanism is adopted in some communication systems, thereby saving the power consumption of terminals. However, in order to further saving the power consumption of terminals, some communication systems, such as a 5 th  generation (5G) system, introduce a power-saving signal, but the power-saving signal in related art only can indicate the terminal to monitor a physical downlink control channel (PDCCH), that is, the terminal monitors the PDCCH after receiving the power-saving signal. Due to the relatively poor indicating performance of the power-saving signal, the power-saving effect of the terminal is relatively poor.

To be precise, the use of the term such as “exemplary” or “for example” is intended to present a related concept in a specific manner. 
     The embodiments of the present disclosure are described below with reference to the accompanying drawings. A power-saving signal receiving method, a power-saving signal sending method, a terminal and a network device provided by the embodiments of the present disclosure may be applied to a wireless communication system. The wireless communications system may be a 5G system, an evolved long term evolution (eLTE) system, or a subsequent evolved communications system. 
     Referring to  FIG. 1 ,  FIG. 1  is a structural diagram of a network system applicable to an embodiment of the present disclosure. As shown in  FIG. 1 , the network system includes: a terminal  11  and a network device  12 , where the terminal  11  may be user equipment (UE) or another terminal side device, for example, 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 robot. It should be noted that a specific type of the terminal  11  is not limited in the embodiment of the present disclosure. The above network device  12  may be a 4 th  generation (4G) base station, or a 5G base station, or a base station of a later version, or a station in other communication systems, or be called as a node B, an evolved node B, or a transmission reception point (TRP), or an access point (AP), or other words in the field. As long as the same technical effect is achieved, the network device is not limited to specific technical words. In addition, the network device  12  may be a master node (MN) or a secondary node (SN). It should be noted that in embodiments of the present disclosure, only the 5G base station is used as an example, but a specific type of the network device is not limited. 
     Referring to  FIG. 2 ,  FIG. 2  is a flowchart of a power-saving signal receiving method according to an embodiment of the present disclosure. The method is applied to a terminal, and as shown in  FIG. 2 , includes the following steps: 
     Step  201 : receiving a power-saving signal, wherein the power-saving signal is used to indicate a terminal state for a serving cell, and the power-saving signal is further used to indicate a behavior of the terminal; 
     the terminal state is one of dormancy (which may be called dormant state or dormancy-like state) and non-dormancy (which may be called non-dormant state or non-dormancy-like state); 
     the behavior of the terminal includes at least one of the following: 
     whether to start a DRX onduration timer, and 
     whether to monitor the PDCCH of the serving cell, wherein the PDCCH is a PDCCH corresponding to a DRX onduration timer associated with the power-saving signal. 
     The power-saving signal may also be called a wake-up signal (WUS) or a sleep signal. The power-saving signal may be used to indicate a plurality of terminals, and may also be used to indicate one terminal. 
     The above indication of the terminal in the serving cell may be: indicating the terminal in one or more serving cells, and in different serving cells may be the same or different, for example: taking a plurality of serving cells as an example, the power-saving signal may indicate in one part of cells as a dormant state, and in the other part of cells as a non-dormant state, or may indicate in all serving cells as a dormant state. 
     The above serving cell may include at least one of the following: 
     a primary cell (Pcell), a primary secondary cell (PScell) and a secondary cell (Scell). 
     The above serving cell may include one or more cells, for example: the above serving cell may refer to one or more cells in one or more cell groups, such as one or more cells in a master cell group (MCG) and one or more cells in a secondary cell group (SCG), or one or more cells in a primary cell group, or one or more cells in a secondary cell group. 
     Preferably, the terminal monitors the power-saving signal sent by the primary cell or the primary secondary cell, that is, the secondary cell does not send the power-saving signal. Of course, solutions which are not limited thereto may also be included. 
     In addition, in the dormant state, the terminal may not monitor the PDCCH of the serving cell, or in the dormant state, the monitoring period for the terminal to monitor the PDCCH of the serving cell may be a first period; and 
     in the non-dormant state, the monitoring period for the terminal to monitor the PDCCH of the serving cell may be a second period, 
     wherein the duration of the first period is greater than the duration of the second period. 
     That the duration of the first period is greater than the duration of the second period may be: the frequency of the terminal monitoring the PDCCH of the serving cell in the dormant state is lower than that of the terminal monitoring the PDCCH of the serving cell in the non-dormant state. 
     For example: in the dormant state, according to the network side configuration, the terminal does not monitor the PDCCH or the period of the terminal monitoring the PDCCH is long, for example, the PDCCH is monitored every 2,560 slots, and in this state, the electricity-saving performance of the terminal is higher; and 
     in the non-dormant state, the terminal monitors the PDCCH frequently according to the network side configuration, for example, the PDCCH is monitored every downlink slot, or the PDCCH is monitored every other one slot, and in this state, the electricity-saving performance of the terminal is lower than that in the dormant state. 
     It should be noted that the first period and the second period may be configured by a network side, or may be agreed by a protocol. 
     Preferably, the PDCCH related to the dormant state and the non-dormant state may be further limited, for example, the PDCCH is a PDCCH scrambled by a cell radio network temporary identifier (C-RNTI) or a configured scheduling radio network temporary identifier (CS-RNTI). Of course, solutions which are not limited thereto may also be included. 
     The whether to start the DRX onduration timer of the serving cell may be: when the power-saving signal indicates the terminal to start the DRX of the serving cell, the terminal starts the DRX onduration timer of the serving cell and monitors the PDCCH in the timer; and in a case that the power-saving signal indicates not to start the DRX onduration timer of the serving cell, the terminal does not start the DRX onduration timer so as to save electricity. 
     The whether to monitor the PDCCH of the serving cell may be: when the power-saving signal indicates the terminal to monitor the PDCCH of the serving cell, the terminal monitors the PDCCH of the serving cell; and in a case that the power-saving signal indicates not to monitor the PDCCH of the serving cell so as to save electricity. 
     In addition, the receiving the power-saving signal may be: receiving the signal sent by a network device, for example: the terminal monitors the power-saving signal in a radio resource control (RRC) connection state, which may further be non active time in the RRC connection state. 
     In the embodiments of the present disclosure, the terminal state and the behavior of the terminal may be flexibly indicated through the above steps, and may be indicated by taking the cell as a unit, thereby improving the power-saving effect of the terminal. Further, the terminal states and behaviors of the terminal in a plurality of serving cells are indicated through one power-saving signal, so that signaling overhead can be saved. 
     As an optional implementation manner, the power-saving signal indicates the terminal states in N serving cells respectively by N bits; or 
     the power-saving signal indicates the terminal states for N serving cells by M bits, wherein M is an integer less than the N, each codepoint of the M bits is used to indicate the terminal states for a plurality of serving cells, and 
     N is an integer greater than 1. 
     The N serving cells may be part of all serving cells in all serving cells or cell groups of the terminal, for example: the N serving cells may be one or more Scells, but not including Pcell/PScell. For example, the power-saving signal does not include the bit indicating the Pcell/PScell terminal, of course, it may also include no limitation thereto. 
     In addition, the above mode of N bits may be: one bit corresponds to one cell, that is, 1 bit of the power-saving signal indicates the terminal state of one cell, so that the terminal in each serving cell can be indicated flexibly and directly, for example, 15 bits respectively indicate in 15 cells. 
     That the terminal states for N serving cells are indicated by M bits may be: M bits adopt joint coding to indicate the terminal states for N serving cells, or adopt other coding modes to indicate the terminal states for N serving cells. 
     That each codepoint is used to indicate the terminal states for a plurality of serving cells may be: each codepoint is used to indicate the terminal state combination of the terminal in all or part of N serving cells, so that a plurality of codepoints of the M bits may indicate a plurality of state combinations. For example, as shown in table 1, in table 1, D/N respectively represents a dormancy/non-dormant state.

     It should be noted that there are only 3 codepoints in table 1 for illustration. Taking 5 bits as an example, there are 32 codepoints in 5 bits, so that 32 codepoints may indicate 32 state combinations of 15 serving cells so as to save the signaling overhead of the power-saving signal. 
     In addition, in some scenarios, in order to simplify the complexity of indicating the terminal in the cell by the power-saving signal, the terminal state combinations of some unimportant terminals may be removed. For example: taking the case where N bits indicate N cells of the terminal as an example, the N bits may be regarded as a bitmap, so that some unimportant codepoints in the bitmap may be excluded. 
     For another example, 15 serving cells may be divided into 5 groups, and each group includes 3 serving cells, so that the terminal states of 5 serving cell groups (totally 15 cells) can be indicated only through the bitmap of 5 bits. The terminal states of three serving cells in one group are the same. 
     The mode of indicating the terminal states for N serving cells by M bits can save the signaling overhead. 
     It should be noted that the mode of indicating the terminal states for N serving cells by N bits or M bits may be configured through the RRC signaling by the network side, or may be agreed by a protocol. 
     Optionally, in a case that the power-saving signal indicates the terminal to start DRX onduration timers of all serving cells, the terminal determines the terminal states for N serving cells according to the N bits or the M bits. 
     That the power-saving signal indicates the terminal to start DRX onduration timers of all serving cells may be: the power-saving signal indicates the terminal to start the DRX onduration timers of all serving cells by 1 bit or a plurality of bits. 
     In this implementation manner, in a case that the terminal is indicated to start the DRX onduration timers of all serving cells, the terminal determines the terminal states for N serving cells according to N bits or M bits. In this way, the error caused by determining the terminal states for N serving cells according to N bits or M bits in a case that the terminal indicates that the DRX onduration timers of all serving cells of the terminal are not started can be avoided, and the power consumption of the terminal can be further saved. 
     Of course, in a case that the power-saving signal indicates the terminal to monitor the PDCCHs of all serving cells by 1 bit, the terminal may also determine the terminal states for N serving cells according to N bits or M bits. 
     Optionally, in a case that the power-saving signal indicates that the DRX onduration timers of all serving cells are not started, and the N bits or M bits indicate the terminal in at least one serving cell is a non-dormant state, 
     the terminal does not expect to receive the power-saving signal; or 
     the terminal performs the non-dormancy behavior for the at least one serving cell. 
     That the power-saving signal indicates the terminal to start DRX onduration timers of all serving cells may be: the power-saving signal indicates the terminal to start the DRX onduration timers of all serving cells by 1 bit or a plurality of bits. 
     That the terminal does not expect to receive the power-saving signal may be: the terminal regards this case as an error case. 
     That the terminal performs the non-dormancy behavior for the at least one serving cell may be: in a case that the DRX onduration timers of all serving cells are not started, the terminal is in a non-dormant state for the serving cell. 
     For example: 1 bit (a 0 ) in the power-saving signal indicates the serving cell in the cell group whether to start the DRX onduration timer, other bits (a 1 , a 2 , a 3 , a 15 ) indicate in a plurality of Scells. For the case where a 0 =0 and at least one of a 1 , a 2 , a 3 , a 15  is 1, processing is as follows: 
     one is that this case is regarded as an error case, and the terminal does not expect to receive this indication; or the other one is that this case is a normal case, and at this time, the terminal does not start the DRX onduration timer, and performs the behavior of the non-dormant state of the corresponding serving cells indicated by a 1 , a 2 , a 3 , a 15 . 
     In this implementation manner, since for the above case, the terminal does not expect to receive the power-saving signal, or the terminal performs the non-dormancy behavior for the at least one serving cell, the power consumption of the terminal can be further saved. 
     Optionally, in a case that the power-saving signal indicates the terminal states in N serving cells to be all dormant states, the N bits or the M bits are further used to indicate at least one of the following: 
     the DRX onduration timers of all serving cells are not started; and 
     the PDCCHs of all serving cells are not monitored. 
     In this implementation manner, in a case that the terminal states in N serving cells are indicated to be the dormant state, it is defaulted that the power-saving signal further indicates at least one of the following: the DRX onduration timers of all serving cells are not started and the PDCCHs of all serving cells are not monitored, so that the signaling overhead is saved. 
     Optionally, in a case that the N bits are a first combination, the N bits or the M bits are further used to indicate at least one of the following: 
     the DRX onduration timers of all serving cells are not started; and 
     the PDCCHs of all serving cells are not monitored. 
     The first combination may be configured through the RRC signaling by the network side, or may be agreed by a protocol. 
     In this implementation manner, in a case that the N bits is the first combination, it is defaulted that the power-saving signal further indicates at least one of the following: the DRX onduration timers of all serving cells are not started and the PDCCHs of all serving cells are not monitored, so that the signaling overhead is saved. 
     In this implementation manner, the power-saving signal may only carry the N bits or the M bits. 
     Optionally, in a case that the M bits are a second combination, the N bits or the M bits are further used to indicate at least one of the following: 
     not starting the DRX onduration timers of all serving cells, 
     and not monitoring the PDCCHs of all serving cells. 
     The second combination may be configured through the RRC signaling by the network side, or may be agreed by a protocol. 
     In this implementation manner, in a case that the M bits is the second combination, it is defaulted that the power-saving signal further indicates at least one of the following: the DRX onduration timers of all serving cells are not started and the PDCCHs of all serving cells are not monitored, so that the signaling overhead is saved. 
     In this implementation manner, the power-saving signal may only carry the N bits or the M bits. 
     Optionally, the power-saving signal may only carry the N bits or the M bits. For example: it is unnecessary to carry the bit dedicated to indicating the above behavior, so as to save the signaling overhead. For example: there is no 1 bit (such as a 0 ) in the power-saving signal to indicate the above behavior, and only a 1 -a 15  are used to indicate in 15 Scells. At this time, a 1 -a 15  may be all equal to 0 to determine that the terminal does not start the DRX onduration timer, or a certain special combination of a 1 -a 15  may be used to indicate not to start the DRX onduration timer. This special combination is configured by the RRC signaling by the network side, or is agreed by a protocol. 
     As an optional implementation manner, the power-saving signal indicates the behavior of the terminal by 1 bit; or 
     the power-saving signal indicates the behavior of the terminal by a plurality of bits. 
     In a case that the power-saving signal indicates the behavior of the terminal by a plurality of bits, the terminal may have the same behavior or different behaviors for a plurality of serving cells. 
     That the above behavior is indicated by 1 bit may be: the behavior of the terminal in each serving cell is indicated by 1 bit to be consistent, for example: in a case that the 1 bit is a first value, it may indicate at least one of the following: starting the DRX onduration timers of all serving cells and monitoring the PDCCHs of all serving cells; and 
     in a case that the 1 bit is a second value, it may indicate at least one of the following: 
     not starting the DRX onduration timers of all serving cells, and not monitoring the PDCCHs of all serving cells. 
     The all serving cells may be all serving cells of the terminal, or may be all serving cells in a cell group. Of course, the all serving cells may refer to all Scells, or may also refer to all serving cells corresponding to in the serving cell indicated by the power-saving signal, for example: the N serving cells. 
     Through the 1 bit indication, a plurality of serving cells may share the same bit, for example: sharing the same MAC entity, so as to save the signaling overhead. Taking the case where the 1 bit is a 0 , (1 bit in the power-saving signal) as an example, a 0  may indicate the serving cell in the cell group whether to start the DRX onduration timer; the terminal receives the power-saving signal, in a case that a 0 =0, the terminal does not start the DRX onduration timer of the serving cell in the cell group; and in a case that a 0 =1, the terminal starts the DRX onduration timer of the serving cell in the cell group. 
     That the power-saving signal indicates the behavior of the terminal through a plurality of bit may be: the behaviors of the terminal in different serving cells are indicated through different bits, for example: the behaviors of the terminal in N serving cells are indicated by N bits, or the behaviors of the terminal in N serving cells are indicated by M bits, for example: a plurality of serving cells respectively adopt the corresponding bit, or corresponding MAC entity for indication. This implementation manner may flexibly configure the behaviors of the terminal in different serving cells so as to save the power consumption of the terminal. 
     Optionally, in a case that the power-saving signal indicates that the terminal in the serving cell is a non-dormant state, the behavior of the terminal is determined according to the 1 bit or the value of the plurality of bits. 
     The 1 bit and the plurality of bits here may be 1 bit and a plurality of bits indicating the behavior of the terminal in the above implementation manner. That the power-saving signal indicates that the terminal in the serving cell is a non-dormant state may be: indicating that the terminal states for N serving cells are the non-dormant state, for example, indication through the N bits or M bits. 
     For example: the power-saving signal includes 16 bits such as a 0 , a 1 , a 2 , a 3 , . . . a 15 , wherein a 0  is used to indicate the above behavior, for example, a 0  indicates the serving cell in the cell group whether to start the DRX onduration timer, and the other bits are used to indicate in 15 serving cells; in a case that the power-saving signal is received and a 1 , a 2 , a 3 , a 15  are all 0, all serving cells in the cell group do not start the DRX onduration timer; and other cases determine whether to start the DRX onduration timer according to a 0 , and a 1 , a 2 , a 3 , a 15  indicate in a plurality of Scells. 
     In this implementation manner, the behavior of the terminal may be determined according to the value of 1 bit only when the power-saving signal indicates that the terminal states for N serving cells are the non-dormant state, otherwise, it may directly determine that the DRX onduration timers of all serving cells are not started, and the PDCCHs of all serving cells are not monitored, so that the complexity is reduced. 
     As an optional implementation manner, in a case that the power-saving signal indicates that the DRX onduration timers of all serving cells are not started, the terminal determines that the bit indicating the terminal in the serving cell in the power-saving signal is invalid, or determines that in the serving cell are all dormant states. 
     It may be: determining that the terminal states for N serving cells are all dormant states. 
     That the power-saving signal indicates the terminal to start DRX onduration timers of all serving cells may be: the power-saving signal indicates the terminal to start the DRX onduration timers of all serving cells by 1 bit or a plurality of bits. 
     In this implementation manner, in a case that the DRX onduration timers of all serving cells are indicated not to be started by 1 bit, it may directly determine that the bit indicating the terminal in the serving cell in the power-saving signal is invalid, or determine that the terminal states for N serving cells are all dormant states, so that the working efficiency of the terminal is improved, and the power consumption of the terminal is further saved. 
     For example: 1 bit (a 0 ) in the power-saving signal indicates the serving cell in the cell group whether to start the DRX onduration timer, other bit (a 1 , a 2 , a 3 , . . . a 15 ) indicates in a plurality of Scells, wherein in a case that a 0 =0, the serving cell in the cell group does not start the DRX onduration timer; in a case that a 0 =1, the serving cell in the cell group starts the DRX onduration timer; any bit of a 1 , a 2 , a 3 , a 15  is 0, then the corresponding Scell is in the dormant state; any bit of a 1 , a 2 , a 3 , . . . a 15  is 1, the corresponding Scell is in the non-dormant state; the behaviors corresponding to a 1 , a 2 , a 3 , a 15  may be take effect only when a 0 =1, that is, when a 0 =0, a 1 -a 15  are invalid indications, not representing the terminal in Scell; or when a 0 =0, the terminal assumes that all cells are in the dormant state. 
     Of course, in a case that the power-saving signal indicates that the PDCCHs of all serving cells of the terminal are not monitored by 1 bit, the terminal also determines that the bit indicating the terminal in the serving cell in the power-saving signal is invalid, or determines that the terminal states for N serving cells are all dormant states. 
     As an optional implementation manner, the method further includes: 
     in a case that the terminal receives the power-saving signal, determining to start DRX onduration timers of all serving cells, and/or monitor PDCCHs of all serving cells. 
     In this implementation manner, as long as receiving the power-saving signal, the terminal determines that the DRX onduration timers of all serving cells are started, and/or the PDCCHs of all serving cells are monitored, so that it may be unnecessary to add other bit to indicate the above behavior, thereby saving the signaling overhead. 
     As an optional implementation manner, after receiving the power-saving signal, the terminal performs at least one of the following according to the indication of the power-saving signal: 
     entering the dormant state or the non-dormant state for the serving cell; 
     starting or not starting the DRX onduration timer of the serving cell; and 
     monitoring or not monitoring the PDCCH of the serving cell. 
     In this implementation manner, at least one of the above may be performed according to the indication of the power-saving signal. 
     In the embodiments of the present disclosure, a power-saving signal is received, wherein the power-saving signal is used to indicate a terminal state for a serving cell, and the power-saving signal is further used to indicate a behavior of the terminal; the terminal state is one of dormancy and non-dormancy; the behavior of the terminal includes at least one of the following: whether to start a DRX onduration timer, and whether to monitor a PDCCH of the serving cell; and the PDCCH is a PDCCH corresponding to a DRX onduration timer associated with the power-saving signal. In this way, the power-saving signal flexibly indicates the terminal state and the behavior of the terminal, so that the power-saving effect of the terminal can be improved. 
     The power-saving signal receiving method provided by the embodiments of the present disclosure will be illustrated below on the basis that the power-saving signal indicates in 15 Scells. 
     Embodiment 1 
     In this embodiment, a power-saving signal includes 16 bit, and explicitly indicates whether to start a DRX onduration timer of a serving cell. 
     1. For an NR carrier aggregation (CA) scenario, assuming one Pcell and 15 Scells, the power-saving signal includes 16 bit, wherein 1 bit (a 0 ) indicates a cell in a cell group whether to start a DRX onduration timer, and other 15 bit (a 1 , a 2 , a 3 , . . . a 15 ) indicates the dormancy/non-dormant state of a plurality of Scell. 
     In a case that a 0 =0, the cell in the cell group does not start the DRX onduration timer; and in a case that a 0 =1, the cell in the cell group starts the DRX onduration timer. 
     Any bit of a 1 , a 2 , a 3 , . . . a 15  is 0, then the corresponding Scell is in the dormant state; and any bit of a 1 , a 2 , a 3 , . . . a 15  is 1, then the corresponding Scell is in the non-dormant state. Optionally, the above behavior takes effect only when a 0 =1, that is, when a 0 =0, a 1 -a 15  are invalid indications, not representing the dormancy/non-dormant state, or when a 0 =0, the terminal assumes that all serving cells are in the dormant state, wherein a 0 =0 may represent that the terminal does not start the DRX onduration timers of all serving cells, at this time, the network device expects the terminal not to monitor the PDCCH, or expects the terminal to be in the dormant state, the optimal solution is that a 1 -a 15  do not take effect at this time. 
     For the case where a 0 =0 and at least one of a 1 , a 2 , a 3 , a 15  is 1, processing is as follows: 
     this case is regarded as an error case, the terminal does not expect to receive this indication; or this case is a normal case, at this time, the terminal does not start the DRX onduration timer, and performs the behavior of the non-dormant state of the corresponding cells indicated by a 1 , a 2 , a 3 , a 15 . 
     Embodiment 2 
     In this embodiment, the power-saving signal includes 15 bits, and implicitly indicates whether to start the DRX onduration timer, for example: at this time, all serving cells are indirectly/implicitly indicated not to start the DRX onduration timer through the values of a 1 , a 2 , a 3 , . . . a 15  (for example the values are all 0, that is, all Scells are in the dormant state), 1 bit, that is, a 0  is saved compared with the solution  1 . 
     For the NRCA scenario, assuming one Pcell and 15 Scells, the power-saving signal includes 15 bits (a 1 , a 2 , a 3 , . . . a 15 ), which respectively indicate the dormancy/non-dormant state of a plurality of Scells, and there is no bit for indicating the related state of the Pcell. 
     a 1 -a 15  are all 0, determining that all serving cells of the terminal do not start the DRX onduration timer; and a 1 -a 15  are not all 0, indicating that all serving cells of the terminal start the DRX onduration timer; or 
     a certain special combination of a 1 -a 15  is used to indicate that all serving cells do not start the DRX onduration timer, and other combinations are used to indicate that all serving cells of UE start the DRX onduration timer; and the special combination is configured through the RRC signaling by the network side, or is predefined by a protocol.

     the fourth rule: determination is performed according to a 1 , a 2 , a 15 , that is, the values of a 1 , a 2 , a 15  are all 0, then the DRX onduration timer is not started.
