Description

Technical Field

[0001] The present disclosure relates to the technical field of communications, and in particular to a method for receiving an energy-saving signal, a method for transmitting an energy-saving signal, a terminal, and a network device.

Background Art

[0002] Energy saving of terminals has always been an important research topic in the technical field of communications. In some communication systems, a discontinuous reception (DRX) mechanism is adopted to save the power consumption of terminals. However, in order to further save the power consumption of terminals, in some communication systems, such as the 5th generation (5G) system, an energy-saving signal has been newly introduced. However, the energy-saving signal in the related art can only instruct the terminal to monitor the physical downlink control channel (PDCCH). That is, after receiving the energy-saving signal, the terminal will monitor the PDCCH. Thus, due to the low instructiveness of the energy-saving signal, the energy-saving effect of the terminal is reduced.

Modes for Carrying Out the Invention

[0013] Hereinafter, while referring to the drawings in the embodiments of the present disclosure, the technical solutions in the embodiments of the present disclosure will be clearly described. The described embodiments are part of the embodiments of the present disclosure, not all of them. Based on the embodiments of the present disclosure, all other embodiments that can be conceived by those skilled in the art shall fall within the protection scope of the present disclosure.

Strictly speaking, the use of terms such as "exemplary" or "for example" aims to show related concepts in a specific form.

[0016] Hereinafter, embodiments of the present disclosure will be described with reference to the drawings. The energy-saving signal receiving method, transmitting method, terminal, and network device provided by the embodiments of the present disclosure are applicable to a wireless communication system. The wireless communication system may be a 5G system, or an evolved long term evolution (eLTE) system, or a subsequent evolved communication system.

[0017] FIG. 1 is a configuration diagram of a network system to which embodiments of the present disclosure are applicable. The system includes a terminal 11 and a network device 12. The terminal 11 may be a user equipment (UE) or other terminal-side devices, 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 the embodiments of the present disclosure do not limit the specific type of the terminal 11. The network device 12 may be a fourth-generation (4G) base station, or a 5G base station, or a base station of a subsequent version, or a base station in other communication systems, or a Node B, an evolved Node B, or a transmission reception point (TRP), or an access point (AP), or other terms in the field. As long as the same technical effect can be achieved, the network device is not limited to a specific technical term. In addition, the network device 12 may be a master node (MN) or a secondary node (SN). It should be noted that in the embodiments of the present disclosure, only a 5G base station is taken as an example, but the specific type of the network device is not limited.

[0018] Figure 2 is a flowchart of a method for receiving an energy-saving signal provided according to an embodiment of the present disclosure. The method is applied to a terminal, receiving an energy-saving signal, where the energy-saving signal indicates the state of the terminal in a serving cell, and and includes step 201 for instructing the operation of the terminal, where the state is either a dormant state (which may also be referred to as a dormancy state or a dormancy-like state) or a non-dormant state (which may also be referred to as a non-dormancy state or a non-dormancy-like state), and the operation of the terminal includes at least one of the operation of whether to start a DRX on-duration timer of the serving cell and the operation of whether to monitor a PDCCH corresponding to the DRX on-duration timer of the serving cell associated with the energy-saving signal.

[0019] The above energy-saving signal may also be referred to as a wake-up signal (WUS) or a sleep signal. The above energy-saving signal may be used to issue instructions to multiple terminals or to a single terminal.

[0020] Instructing the state of the terminal in a serving cell may also be instructing the state of the terminal in one or more serving cells, and the states of the terminals in different serving cells may be the same or different. For example, taking multiple serving cells as an example, the above energy-saving signal can indicate that the state of the terminal in some cells is a dormant state and the state of the terminal in another part of the cells is a non-dormant state, or can indicate that the state of the terminal is a dormant state in all serving cells, etc. The above serving cell It may include at least one of a Primary Cell (Pcell), a Primary Secondary Cell (PScell), and a Secondary Cell (Scell).

[0021] The serving cell may include one or more cells. For example, the serving cell may refer to one or more cells within one or more cell groups, for example, one or more cells within a Master Cell Group (MCG) and one or more cells within a Secondary Cell Group (SCG), or one or more cells within a master cell group, or one or more cells within a secondary cell group.

[0022] Preferably, the terminal monitors the energy-saving signal transmitted from the primary cell or the primary secondary cell, that is, the secondary cell does not transmit the energy-saving signal. It may include solutions that do not limit this.

[0023] Also, in the idle state, the terminal may not monitor the PDCCH of the serving cell. Or, in the idle state, the monitoring period during which the terminal monitors the PDCCH of the serving cell may be the first period. In the non-idle state, the monitoring period during which the terminal monitors the PDCCH of the serving cell may be the second period. The length of the first period exceeds the length of the second period.

[0024] The fact that the length of the first period exceeds the length of the second period may mean that the frequency at which the terminal monitors the PDCCH of the serving cell in the idle state is lower than the frequency at which the terminal monitors the PDCCH of the serving cell in the non-idle state.

[0025] For example, in the idle state, depending on the network-side settings, the terminal either does not monitor the PDCCH or the period for monitoring the PDCCH becomes very long, such as monitoring the PDCCH once every 2560 time slots (slots). In this state, the power saving performance of the terminal is even higher. In the non-idle state, depending on the network-side settings, the terminal frequently monitors the PDCCH, for example, monitors the PDCCH for each downlink slot or monitors the PDCCH every other slot. In this state, the power saving performance of the terminal is lower than that in the idle state.

[0026] It should be noted that the above first period and second period may be set on the network side or may be defined by the protocol.

[0027] Preferably, the PDCCH related to the above idle state and non-idle state can be further limited. For example, the PDCCH is a PDCCH scrambled with a Cell Radio Network Temporary Identifier (C-RNTI) or a Configured Scheduling Radio Network Temporary Identifier (CS-RNTI). It may also include solutions that do not limit this.

[0028] Regarding the operation of whether to start the DRX on-duration timer of the serving cell, when the terminal is instructed by the power-saving terminal to start the DRX of the serving cell, the terminal starts the DRX on-duration timer of the serving cell and monitors the PDCCH within the timer. When it is instructed not to start the DRX on-duration timer of the serving cell, the terminal may not start the DRX on-duration timer for power saving.

[0029] The operation of whether to monitor the PDCCH of the serving cell is as follows: when the energy-saving terminal instructs the terminal to monitor the PDCCH of the serving cell, the terminal monitors the PDCCH of the serving cell; when the terminal is instructed not to monitor the PDCCH of the serving cell, the terminal may not monitor the PDCCH of the serving cell for power saving.

[0030] Also, the reception of the energy-saving signal may be the reception of the transmission from the network device. For example, the terminal can monitor the above energy-saving signal in the Radio Resource Control (RRC) connected state, and further in the non-active time in the RRC connected state.

[0031] In the embodiments of the present disclosure, through the above steps, the state and operation of the terminal can be flexibly instructed, and by issuing instructions in units of cells, the energy-saving effect of the terminal can be enhanced. Furthermore, since the state and operation of the terminal in a plurality of serving cells are instructed by one energy-saving signal, signaling overhead can also be saved.

[0032] As an alternative embodiment, the energy-saving signal respectively instructs the state of the terminal in N serving cells by N bits, or the energy-saving signal instructs the state of the terminal in N serving cells by M bits, where M is an integer smaller than N, and each code point of the M bits is used to instruct the state of the terminal in a plurality of serving cells, and N is an integer greater than 1.

[0033] The above N serving cells may be all the serving cells of the terminal or some or all of the serving cells within a cell group. For example, without including Pcell / PScell, one or more Scells may be used so that the energy-saving signal does not include bits indicating the state of the terminal in Pcell / Pscell, and it may include a solution that does not limit this.

[0034] Also, in the form of the above N bits, for example, one bit may correspond to one cell so that 15 bits respectively indicate the state of the terminal in 15 cells, that is, one bit of the energy-saving signal indicates the state of one cell, whereby the state of the terminal in each serving cell can be flexibly and directly indicated.

[0035] Indicating the state of the terminal in N serving cells by M bits may be such that M bits indicate the state of the terminal in N serving cells by joint coding or indicate the state of the terminal in N serving cells by other coding methods.

[0036] The fact that each code point is used to indicate the state of the terminal in a plurality of serving cells may be such that each code point is used to indicate a combination of the states of the terminal in all or some of the N serving cells, whereby a plurality of code points of M bits can indicate a combination of a plurality of states. For example, as shown in Table 1, D / N in Table 1 represents the dormancy / non-dormancy state respectively.

[0037]

Table 1

[0038] It should be noted that in Table 1, only three code points are taken as examples for explanation. Taking 5 bits as an example, there are 32 types of code points in 5 bits. Thus, the 32 types of code points can indicate the combinations of 32 states of 15 serving cells, achieving the purpose of reducing the signaling overhead of the energy-saving signal.

[0039] Also, in some scenarios, in order to reduce the complexity of the energy-saving signal indicating the state of the terminal in the cell, some unimportant state combinations of the terminal in multiple serving cells may be excluded. For example, when taking the case where N bits indicate N serving cells of the terminal, these N bits may be regarded as a single bitmap, whereby some unimportant code points in the bitmap can be excluded.

[0040] Furthermore, for example, 15 serving cells may be divided into 5 groups, with each group containing 3 serving cells. Thus, only a 5-bit bitmap can be used to indicate the states of 5 groups of serving cells (a total of 15 cells). The states of the 3 serving cells within one group are all the same.

[0041] The method of using M bits to indicate the state of the terminal in N serving cells can save signaling overhead.

[0042] It should be noted that the method of using the above N bits or M bits to indicate the state of the terminal in N serving cells may be set by RRC signaling on the network side or may be specified by the protocol.

[0043] Optionally, when the energy-saving signal indicates that the terminal starts the DRX on-duration timer for all serving cells, the terminal determines the state of the terminal in N serving cells according to the N bits or the M bits.

[0044] It may be that the energy-saving signal instructs the terminal to start the DRX on-duration timers of all serving cells, such that the energy-saving signal instructs the terminal to start the DRX on-duration timers of all serving cells by the above 1 bit or multiple bits.

[0045] In this embodiment, when the terminal is instructed to start the DRX on-duration timers of all serving cells, the terminal can first determine the state of the terminal in N serving cells according to N bits or M bits. Thus, when the terminal is instructed not to start the DRX on-duration timers in all serving cells, an error caused by the terminal determining the state of the terminal in N serving cells according to N bits or M bits can be avoided, and further power consumption of the terminal can be saved.

[0046] Even when the energy-saving signal instructs the terminal to monitor the PDCCH of all serving cells by 1 bit, the terminal can determine the state of the terminal in N serving cells according to N bits or M bits.

[0047] Optionally, when the energy-saving signal instructs not to start the DRX on-duration timers in all serving cells, and the N bits or the M bits indicate that the state of the terminal in at least one serving cell is a non-idle state, the terminal does not expect to receive the energy-saving signal, or the terminal performs an operation of executing a non-idle state for the at least one serving cell.

[0048] The energy-saving signal may indicate that the terminal does not start the DRX on-duration timers of all serving cells, in such a way that the energy-saving signal indicates this by the above-mentioned 1 bit or multiple bits.

[0049] The terminal may consider such a state as an error state when it does not expect to receive the energy-saving signal.

[0050] When the terminal performs an operation of executing a non-idle state for the at least one serving cell, if the DRX on-duration timers are not started in all serving cells, the terminal may perform a non-idle state for the serving cell.

[0051] For example, 1 bit (a0) in the energy-saving signal indicates whether to start the DRX on-duration timer in the serving cells within the cell group, and another bits (a1, a2, a3, ··· a15) indicate the state of the terminal in multiple Scells. When a0 = 0 and at least one of a1, a2, a3, ··· a15 is 1, there are the following two processing methods. One is to consider such a state as an error state, and the terminal does not expect to receive such an instruction. The other is that such a state is a normal state. At this time, the terminal does not start the DRX on-duration timer, and executes the operation in the non-idle state of the corresponding serving cell indicated by a1, a2, a3, ··· a15.

[0052] In this embodiment, in the above cases, since the terminal does not expect to receive the energy-saving signal or the terminal performs an operation of executing a non-idle state for the at least one serving cell, the power consumption of the terminal can be further saved.

[0053] Optionally, when the energy saving signal indicates that the states of the terminal in the N serving cells are all in the idle state, the N bits or the M bits are further used to indicate at least one of not starting a DRX on-duration timer in all serving cells and not monitoring PDCCH in all serving cells.

[0054] In this embodiment, when it is indicated that the states in the N serving cells are all in the idle state, the energy saving signal can further indicate at least one of not starting a DRX on-duration timer in all serving cells and not monitoring PDCCH in all serving cells by default, thereby saving signaling overhead.

[0055] Optionally, when the N bits are in the first combination, the N bits or the M bits are further used to indicate at least one of not starting a DRX on-duration timer in all serving cells and not monitoring PDCCH in all serving cells.

[0056] The first combination may be set by RRC signaling on the network side or may be defined by a protocol or the like.

[0057] In this embodiment, when the N bits are in the first combination, the energy saving signal can further indicate at least one of not starting a DRX on-duration timer in all serving cells and not monitoring PDCCH in all serving cells by default. This saves signaling overhead.

[0058] In this embodiment, the energy-saving signal may carry only the N bits or the M bits.

[0059] Optionally, when the M bits are in a second combination, the N bits or the M bits are further used to indicate at least one of not starting a DRX on-duration timer in all serving cells and not monitoring PDCCH in all serving cells.

[0060] The second combination may be set by RRC signaling on the network side, or may be defined by a protocol or the like.

[0061] In this embodiment, when the M bits are in the second combination, the energy-saving signal can, by default, further indicate at least one of not starting a DRX on-duration timer in all serving cells and not monitoring PDCCH in all serving cells, thereby saving signaling overhead.

[0062] In this embodiment, the energy-saving signal may carry only the N bits or the M bits.

[0063] Optionally, the energy-saving signal may carry only the N bits or the M bits. For example, there is no need to carry the bits specifically used for instructing the above operations, and signaling overhead is saved. For example, in the energy-saving signal, there is no 1-bit (e.g., a0) for instructing the above operations, and only a1 - a15 for instructing the states of the terminals in 15 Scells exist. At this time, when all of a1 - a15 are 0, it may be determined that the terminal does not start the DRX on-duration timer, or a specific special combination of a1 - a15 may be used to instruct not to start the DRX on-duration timer. The special combination is set by RRC signaling on the network side or defined by the protocol.

[0064] As an alternative embodiment, the energy-saving signal may instruct the operation of the terminal by 1 bit, or the energy-saving signal may instruct the operation of the terminal by a plurality of bits.

[0065] When the energy-saving signal instructs the operation of the terminal by a plurality of bits, the terminal may have the same or different operations for a plurality of serving cells.

[0066] Instructing the above operation by 1 bit may be such that 1 bit is used to instruct that the terminal operates uniformly in each serving cell. For example, when the 1 bit is a first value, at least one of starting the DRX on-duration timer for all serving cells and monitoring the PDCCH for all serving cells can be instructed. When the 1 bit is a second value, at least one of not starting the DRX on-duration timer in all serving cells and not monitoring the PDCCH in all serving cells can be instructed.

[0067] All of the above serving cells may be all of the serving cells of the above terminal, or all of the serving cells within a cell group, or all of the Scells. Or all of the serving cells corresponding to the state of the terminal in the serving cell indicated by the above energy-saving signal, for example, the above N serving cells may be used.

[0068] With the above indication by 1 bit, multiple serving cells can share the same bit, for example, the same MAC entity, to save signaling overhead. Taking the case where the above 1 bit is a0 (1 bit within the energy-saving signal) as an example, a0 can indicate whether to start the DRX on-duration timer in the serving cells within the cell group. When the terminal receives the energy-saving signal, if a0 = 0, the terminal does not start the DRX on-duration timer of the serving cells within the cell group; if a0 = 1, the terminal starts the DRX on-duration timer of the serving cells within the cell group.

[0069] When the energy-saving signal instructs the operation of the terminal by multiple bits, it may instruct the operation of the terminal in different serving cells by different bits. For example, it may instruct the operation of the terminal in N serving cells by N bits, or instruct the operation of the terminal in N serving cells by M bits. For example, for multiple serving cells, each corresponding bit or each corresponding MAC entity is adopted for indication respectively. In this embodiment, by flexibly setting the operation of the terminal in different serving cells, the power consumption of the terminal can be saved.

[0070] Optionally, when the energy-saving signal indicates that there is a non-idle state in the state of the terminal in the serving cell, the operation of the terminal is determined according to the value of the 1 bit or the multiple bits.

[0071] This one bit and multiple bits may be the one bit and multiple bits that instruct the operation of the terminal in the above embodiment. The energy-saving signal indicating that there is a non-idle state in the state of the terminal in the serving cell may indicate, for example, by the above N bits or M bits, that there is a non-idle state in the state of the terminal in N serving cells.

[0072] For example, the energy-saving signal includes 16 bits with a0, a1, a2, a3, ··· a15. Among them, a0 is used to instruct the above operation. For example, a0 indicates whether to start the DRX on-duration timer in the serving cell of the cell group. The other bits are used to instruct the state of the terminal in 15 serving cells. When the energy-saving signal is received, if a1, a2, a3, ··· a15 are all 0, the DRX on-duration timer is not started in all serving cells in the cell group. Otherwise, it is determined whether to start the DRX on-duration timer according to a0, and a1, a2, a3, ··· a15 indicate the state of the terminal in multiple Scells.

[0073] In this embodiment, only when the energy-saving signal indicates that there is a non-idle state in the state of the terminal in N serving cells, the operation of the terminal is determined according to the value of one bit. Otherwise, it is possible to directly determine that the DRX on-duration timer is not started in all serving cells and the PDCCH is not monitored in all serving cells, thereby reducing the complexity.

[0074] As a selective embodiment, when the energy-saving signal instructs not to start the DRX on-duration timer in all serving cells, the terminal determines that the bit indicating the state of the terminal in the serving cell in the energy-saving signal is invalid, or determines that the states of the terminal in all serving cells are in a dormant state.

[0075] It may be determined that the states of the terminal in N serving cells are all in a dormant state.

[0076] The energy-saving signal instructing the terminal to start the DRX on-duration timer in all serving cells may be such that the energy-saving signal instructs the terminal to start the DRX on-duration timer in all serving cells by the one bit or a plurality of bits.

[0077] In this embodiment, when it is instructed by one bit not to start the DRX on-duration timer in all serving cells, it is possible to directly determine that the bit indicating the state of the terminal in the serving cell in the energy-saving signal is invalid, or determine that the states of the terminal in N serving cells are all in a dormant state, thereby improving the working efficiency of the terminal and further saving the power consumption of the terminal.

[0078] For example, one bit (a0) in the energy-saving signal indicates whether to start the DRX on-duration timer in the serving cell within the cell group, and the other bits (a1, a2, a3, ··· a15) indicate the state of the terminal in a plurality of Scells. When a0 = 0, the DRX on-duration timer is not started in the serving cell within the cell group. When a0 = 1, the DRX on-duration timer is started in the serving cell within the cell group. When any of the bits a1, a2, a3, ··· a15 is 0, the corresponding Scell is in the dormancy state. When any of the bits a1, a2, a3, ··· a15 is 1, the corresponding Scell is in the non-dormancy state. The operations corresponding to a1, a2, a3, ··· a15 may be effective only when a0 = 1. That is, when a0 = 0, a1 to a15 are invalid instructions and cannot represent the state of the terminal in the Scell. Alternatively, when a0 = 0, the terminal assumes that all cells are in the dormancy state.

[0079] When the energy-saving signal indicates by one bit that the terminal does not monitor the PDCCH in all serving cells, the terminal also determines that the bits indicating the state of the terminal in the serving cell among the energy-saving signals are invalid, or determines that the states of the terminal in N serving cells are all in the idle state.

[0080] As an alternative embodiment, the method further includes, when the terminal receives the energy-saving signal, determining to start the DRX on-duration timers of all serving cells and / or monitor the PDCCHs of all serving cells.

[0081] In this embodiment, if the terminal receives the above energy-saving signal, it becomes possible to start the DRX on-duration timers of all serving cells and / or determine to monitor the PDCCH of all serving cells. As a result, there is no need to add other bits to indicate the above operations, and signaling overhead is saved.

[0082] As an alternative embodiment, after receiving the energy-saving signal, the terminal, in response to the indication of the energy-saving signal, transitions the serving cell to a dormant state or a non-dormant state, starts or does not start the DRX on-duration timer of the serving cell, and performs at least one of monitoring or not monitoring the PDCCH of the serving cell.

[0083] In this embodiment, it becomes possible to perform at least one of the above according to the indication of the energy-saving signal.

[0084] In an embodiment of the present disclosure, an energy-saving signal for indicating the state of the terminal in a serving cell and and indicating the operation of the terminal is received. The state is one of a dormant state and a non-dormant state, and the operation of the terminal includes at least one of an operation of starting or not starting the DRX on-duration timer of the serving cell and an operation of monitoring or not monitoring the PDCCH corresponding to the DRX on-duration timer of the serving cell associated with the energy-saving signal. In this way, the energy-saving signal can enhance the energy-saving effect of the terminal by flexibly indicating the state and operation of the terminal.

[0085] In the following, taking the example that the energy-saving signal indicates the state of the terminal in 15 Scells, a method for receiving the energy-saving signal provided by the embodiment of the present disclosure will be described.

[0086] Example 1 In this embodiment, the energy-saving signal includes 16 bits and explicitly indicates whether to start the DRX on-duration timer of the serving cell. Here, 1. For the scenario of NR Carrier Aggregation (CA), assume one Pcell and 15 Scells. The energy-saving signal includes 16 bits. Among them, 1 bit (a0) indicates whether to start the DRX on-duration timer in the cells of the cell group, and the other 15 bits (a1, a2, a3, ··· a15) indicate the dormancy / non-dormancy states of multiple Scells.

[0087] If a0 = 0, the DRX on-duration timer of the cells in the cell group is not started. If a0 = 1, the DRX on-duration timer of the cells in the cell group is started.

[0088] When any of the bits a1, a2, a3, ··· a15 is 0, the corresponding Scell is in the dormancy state. When any of the bits a1, a2, a3, ··· a15 is 1, the corresponding Scell is in the non-dormancy state. Optionally, the above operation is only effective when a0 = 1. That is, when a0 = 0, a1 - a15 are invalid instructions and cannot represent the dormancy / non-dormancy state. Or, when a0 = 0, the terminal assumes that all serving cells are in the dormancy state. Here, a0 = 0 may indicate that the terminal does not start the DRX on-duration timer of all serving cells. At this time, the network device expects that the terminal does not monitor the PDCCH or expects that the terminal is in the dormancy state. Therefore, the optimal solution is that a1 - a15 are not valid at this time.

[0089] The processing method when a0 = 0 and at least one of a1, a2, a3, ··· a15 is 1 is Such a state is regarded as an error state, and the terminal does not expect to receive such an instruction, or such a state is a normal state. At this time, the terminal does not start the DRX on-duration timer, and executes the operation in the non-dormancy state of the corresponding cell as indicated by a1, a2, a3, ··· a15.

[0090] Embodiment 2 In this embodiment, the energy-saving signal includes 15 bits, implicitly indicating whether to start the DRX on-duration timer. For example, at this time, the values of a1, a2, a3, ··· a15 (for example, if all are 0, all sCells are in the dormancy state) indirectly / implicitly indicate that the DRX on-duration timers of all serving cells are not started. Compared with Solution 1, 1 bit, that is, a0, is saved.

[0091] Regarding the NR CA scenario, assuming one Pcell and 15 Scells, the energy-saving signal includes 15 bits (a1, a2, a3, ··· a15), respectively indicating the dormancy / non-dormancy states of multiple Scells, but does not indicate the bit of the state regarding the Pcell.

[0092] That a1 - a15 are all 0 determines that the DRX on-duration timers of all serving cells of the terminal are not started, and that they are not all 0 indicates to start the DRX on-duration timers of all serving cells of the terminal. Or, A specific special combination of a1 to a15 indicates that the DRX on-duration timers of all serving cells are not started, and other combinations indicate to start the DRX on-duration timers of all serving cells of the UE. The special combination is set by RRC signaling on the network side or is predefined in the protocol.

[0093] In Example 2, compared with Example 1, the cost of 1 bit is saved.

[0094] The embodiments of the present disclosure can be realized as follows.

[0095] First, a terminal in the RRC connected state receives an energy-saving signal transmitted from the network side, and the energy-saving signal indicates the dormancy / non-dormancy state of cells within a cell group (MCG or SCG). One solution is to indicate in a one-to-one manner such as 1 bit for 1 cell. Another solution is to adopt the method of joint coding.

[0096] Second, the energy-saving signal simultaneously indicates whether to start the DRX on-duration timer of the cell or whether to monitor the PDCCH of the DRX on-duration timer associated with the energy-saving signal of the cell. One solution is that all cells share one MAC entity as indicated by 1 bit. Another solution is that different cells each have their own MAC entity as indicated by a plurality of bits.

[0097] Third, for the rule of whether the terminal starts the DRX on-duration timer, when the UE receives the energy-saving signal, the first rule of starting the DRX on-duration timer for all cells, and the second rule of determining whether to start the DRX on-duration timer according to the value of a0, and make a decision according to a0, and exclude the case where all are 0, that is, when a0 = 1 and the values of a1, a2,..a15 are not all 0, start the DRX on-duration timer, otherwise, do not start the DRX on-duration timer. A decision is made according to a1, a2,.. a15. That is, if all the values of a1, a2,.. a15 are 0, a fourth rule of not starting the DRX on-duration timer is included.

[0098] Fourth, one bit (a0) in the energy-saving signal indicates whether to start the DRX on-duration timer of the cells in the cell group, and the other bits (a1, a2, a3, ··· a15) indicate the dormancy / non-dormancy states of a plurality of Scells.

[0099] Fifth, the energy-saving signal includes 15 bits and implicitly indicates whether to start the DRX on-duration timer. At this time, the values of a1, a2, a3, ··· a15 (for example, if all are 0, all the Scells are in the dormancy state) indirectly / implicitly indicate not to start the DRX on-duration timer of all the cells, and one bit, that is, a0 is saved.
