Description

Energy-saving methods, devices, terminals and network-side equipment

[0001] Cross-reference to related applications

[0002] This application claims priority to Chinese Patent Application No. 202410937138.8, filed in China on July 12, 2024, the entire contents of which are incorporated herein by reference. Technical Field

[0003] This application belongs to the field of communication technology, and specifically relates to an energy-saving method, device, terminal and network-side equipment. Background Technology

[0004] A low-power receiver, also known as a low-power wake-up radio (LP-WUR) or near-zero power radio (AZP-WUR), operates on the principle that the receiver comprises a primary communication module (PCM) for transmitting and receiving mobile communication data, and a secondary module (LP-WUR) for receiving low-power wake-up signals (LP-WUS). In power-saving mode, the terminal activates the LP-WUS to listen for LP-WUS and disables the PCM. When downlink data arrives, the network sends a wake-up signal to the terminal. The terminal listens for the wake-up signal through the LP-WUS and, after a series of checks, triggers the PCM to switch from off to on. Simultaneously, the LP-WUS switches from active to off. The LP-WUS can be continuously or intermittently activated, and when active, it receives the LP-WUS.

[0005] Connected Discontinuous Reception (C-DRX) on the terminal side allows the terminal to periodically enter a sleep state and not listen to the Physical Downlink Control Channel (PDCCH); when listening to the PDCCH, it wakes up from the sleep state, thereby saving power.

[0006] The main energy-saving principle of cell discontinuous transmission (cell DTX or cell discontinuous reception, cell DRX) is that the network aligns the DRX on-duration of different terminals, ensuring that the on-duration of terminal C-DRX and the on-duration of cell DTX / DRX are aligned or at least partially overlap. Alignment means that the cell DTX / DRX and terminal C-DRX periods should be multiples of each other. Therefore, the cell can shut down some or all of the base station's signal transmission and reception, or shut down certain base station devices, during the aligned cell DTX / DRX off-duration, to achieve energy savings.

[0007] In related technologies, networks supporting cell DTX / DRX can enable cell DTX / DRX mode for one or more serving cells to save energy; while terminals supporting LP-WUS can enable or activate LP-WUS to save energy. However, existing solutions do not address how to balance the energy saving of cells configured with cell DTX / DRX with the energy saving of terminals configured with LP-WUS. Summary of the Invention

[0008] This application provides an energy-saving method, apparatus, terminal, and network-side equipment that can solve the problem of balancing energy saving in cells configured with cell DTX / DRX and energy saving in terminals configured with LP-WUS.

[0158] The energy-saving method provided in this application will be described in detail below with reference to the accompanying drawings and through some embodiments and application scenarios.

[0159] It should be noted that the serving cell described in the embodiments of this application can also be referred to as a cell or a carrier.

[0160] If the Main Radio (MR) module uses carrier aggregation and has multiple serving cells, the serving cell for transmitting LP-WUS can be one of the configured serving cells in the MR configuration; or the serving cell for transmitting LP-WUS can be one of the active serving cells in the MR activation pool. Alternatively,

[0161] Optionally, if the serving cell operated by the MR may be different from the serving cell operated by the Low Power Wake Up Radio (LP-WUR), then the frequency band of the serving cell of the LP-WUR and at least one frequency band of the one or more serving cells operated by the MR must be the same or unrestricted.

[0162] Optionally, the "cell-level discontinuous transmission" described in the embodiments of this application includes at least one of cell-level discontinuous transmission (Cell-DTX) and cell-level discontinuous reception (Cell-DRX).

[0163] As shown in Figure 2, this application embodiment provides an energy-saving method, which includes:

[0164] Step 201: When the first low-power wake-up signal is monitored and cell-level discontinuous transmission is configured in the first serving cell, the terminal performs at least one of the following operations:

[0165] If the cell-level discontinuous transmission of the first serving cell has been disabled or deactivated, monitor the first low-power wake-up signal; for ease of description, this operation is referred to as operation A in this embodiment of the application.

[0166] If cell-level discontinuous transmission of the first serving cell has been activated, and the first serving cell is in the active period of cell-level discontinuous transmission, monitor the first low-power wake-up signal; for ease of description, this operation is referred to as operation B in this embodiment of the application.

[0167] If cell-level discontinuous transmission of the first serving cell has been activated, and the first serving cell is not in the active period of cell-level discontinuous transmission, the first low-power wake-up signal is not monitored; for ease of description, this operation is referred to as operation C in this embodiment.

[0168] If cell-level discontinuous transmission of the first serving cell has been activated, and the first serving cell is not in the active period of cell-level discontinuous transmission, monitor the first low-power wake-up signal; for ease of description, this operation is referred to as operation D in this embodiment.

[0169] If cell-level discontinuous transmission of the first serving cell has been activated, monitor the first low-power wake-up signal; for ease of description, this operation is referred to as operation E in this embodiment.

[0170] It should be noted that the terminal mentioned in the embodiments of this application may also be a medium access control (MAC) entity on the terminal side, and no specific limitation is made here.

[0171] In this embodiment, different configurations of low-power wake-up signals (LP-WUS) and / or different PDCCH monitoring physical processes triggered by low-power wake-up signals result in different behaviors of the terminal in monitoring LP-WUS on the first serving cell where cell-level discontinuous transmission is configured or activated; that is, the terminal selects at least one of the above operations A to E to perform based on the configuration of LP-WUS and / or the PDCCH monitoring process triggered by LP-WUS.

[0172] Optionally, "not monitoring the first low-power wake-up signal" in operation C above can be understood as: the terminal is not required to monitor the first low-power wake-up signal, or whether or not to monitor the first low-power wake-up signal depends on the implementation of the terminal. The terminal may choose not to monitor the first low-power wake-up signal or it may monitor the first low-power wake-up signal; or the terminal does not expect to monitor the first low-power wake-up signal.

[0173] Optionally, the terminal cannot perform both operation C and operation D simultaneously.

[0174] Alternatively, operation A above can also be expressed as:

[0175] If the cell-level discontinuous transmission (such as Cell-DTX or Cell-DRX) of the first serving cell has been disabled or deactivated, the terminal monitors LP-WUS according to the configuration information of the low-power wake-up signal (such as LP-WUS) on the first serving cell; that is, deactivated Cell-DTX will not change the monitoring timing of LP-WUS or deactivated Cell-DTX will not change the effectiveness and availability of LP-WUS resources.

[0176] Alternatively, operation B above can also be expressed as:

[0177] If the first serving cell is in the active period of cell-level discontinuous transmission (such as Cell-DTX or Cell-DRX), the terminal monitors low-power wake-up signals (such as LP-WUS) during the Cell-DTX active period; that is, the timing of LP-WUS monitoring or the availability and effectiveness of LP-WUS resources during the Cell-DTX active period.

[0178] Alternatively, the above operation C can also be expressed as:

[0179] If the first serving cell is not in the active period of cell-level discontinuous transmission (such as Cell-DTX or Cell-DRX), the terminal does not monitor the low-power wake-up signal (such as LP-WUS) configured or activated on the first serving cell.

[0180] Alternatively, if the first serving cell is in an inactive or not-active period of cell-level discontinuous transmission (such as Cell-DTX or Cell-DRX), the detection timing of LP-WUS or LP-WUS resources are unavailable and invalid during the Cell-DTX inactive period.

[0181] Optionally, the phrase "the first serving cell is not in the active period of cell-level discontinuous transmission" mentioned in the embodiments of this application can also be referred to as "the first serving cell is in the inactive period of cell-level discontinuous transmission"; "active period" can also be referred to as "active time"; "inactive period" can also be referred to as "inactive time", and no specific limitation is made here.

[0182] In this embodiment of the application, in operations A, B and C above, the first serving cell sends a wake-up signal (WUS) to terminals with service needs during the Cell-DTX activity period, and the terminal monitors the WUS only during the Cell-DTX activity period; once the terminal detects the WUS, it triggers the terminal to monitor the Physical Downlink Control Channel (PDCCH), and energy saving can be achieved on both the terminal side and the network side.

[0183] Alternatively, the above operation D can also be expressed as:

[0184] If the first serving cell is not in the active period of cell-level discontinuous transmission (such as Cell-DTX or Cell-DRX), the terminal needs to monitor the low-power wake-up signal (such as LP-WUS) configured or activated on the first serving cell. That is, Cell-DTX has no effect on whether the terminal monitors LP-WUS or when it monitors LP-WUS.

[0185] Alternatively, the above operation E can also be expressed as:

[0186] If cell-level discontinuous transmission of the first serving cell is activated, the terminal needs to monitor the low-power wake-up signal (such as LP-WUS) configured or activated on the first serving cell, regardless of whether the first serving cell is in the Cell-DTX active period. That is, Cell-DTX has no effect on whether the terminal monitors LP-WUS or when it monitors LP-WUS.

[0187] In this embodiment of the application, in the above operations D and E, the first serving cell can more flexibly choose when to send LP-WUS, which can realize network-side energy saving; while the terminal needs to monitor LP-WUS during both the active and inactive periods of Cell-DTX, which can reduce the latency of service scheduling transmission.

[0188] In an optional embodiment of this application, the above operation D includes:

[0189] If cell-level discontinuous transmission of the first serving cell is activated, and the first serving cell is not in the active period of cell-level discontinuous transmission, the first low-power wake-up signal is monitored if a first condition is met; the first condition includes at least one of the following:

[0190] The first serving cell has a running first timer in any of the discontinuous transmission groups to which it belongs;

[0191] The terminal sends a scheduling request to the first serving cell via the physical uplink control channel, and the scheduling request is in a pending state.

[0192] Multicast service is configured on any of the serving cells in the discontinuous transmission group to which the first serving cell belongs;

[0193] Multicast service is configured on the primary cell in the discontinuous transmission group to which the first serving cell belongs;

[0194] The first timer includes at least one of the following: uplink retransmission timer for discontinuous transmission (drx-RetransmissionTimerUL), downlink retransmission timer for discontinuous transmission (drx-RetransmissionTimerDL), and pass-through retransmission timer for discontinuous transmission (drx-RetransmissionTimerSL).

[0195] In another optional embodiment of this application, the above operation E includes:

[0196] If cell-level discontinuous transmission of the first serving cell is activated, the first low-power wake-up signal is monitored if the second condition is met; the second condition includes at least one of the following:

[0197] The first serving cell has a running first timer in any of the discontinuous transmission groups to which it belongs;

[0198] The terminal sends a scheduling request to the first serving cell via the physical uplink control channel, and the scheduling request is in a pending state.

[0199] Multicast service is configured on any of the serving cells in the discontinuous transmission group to which the first serving cell belongs;

[0200] Multicast service is configured on the primary cell in the discontinuous transmission group to which the first serving cell belongs;

[0201] The first timer includes at least one of the following: uplink retransmission timer for discontinuous transmission (drx-RetransmissionTimerUL), downlink retransmission timer for discontinuous transmission (drx-RetransmissionTimerDL), and pass-through retransmission timer for discontinuous transmission (drx-RetransmissionTimerSL).

[0202] Based on operation D or operation E, in order to further help the terminal save energy, this application embodiment points out that the terminal monitors WUS only when the first condition or the second condition is met, regardless of whether the Cell-DTX is active or inactive; if the first condition or the second condition is not met, the terminal does not need to monitor WUS during the inactive period of cell-DTX.

[0203] In summary, in this embodiment of the application, when the first low-power wake-up signal is monitored and cell-level discontinuous transmission is configured in the first serving cell, the operation of the terminal is limited, thereby achieving the goal of balancing the energy saving of the terminal and the energy saving of the first serving cell.

[0204] As shown in Figure 3, this application embodiment also provides an energy-saving method, which includes:

[0205] Step 301: When the first serving cell is configured with monitoring of the first low-power wake-up signal and cell-level discontinuous transmission, the network-side device of the first serving cell performs at least one of the following operations:

[0206] If the cell-level discontinuous transmission of the first serving cell has been disabled or deactivated, the first low-power wake-up signal is sent according to the configuration information of the low-power wake-up signal; for ease of description, this operation is referred to as operation F in this embodiment of the application.

[0207] If cell-level discontinuous transmission of the first serving cell has been activated and the first serving cell is in the active period of cell-level discontinuous transmission, the first low-power wake-up signal is sent according to the configuration information of the low-power wake-up signal; for ease of description, this operation is referred to as operation G in this embodiment of the application.

[0208] If cell-level discontinuous transmission of the first serving cell is activated, and the first serving cell is not in the active period of cell-level discontinuous transmission, the first low-power wake-up signal is not sent; for ease of description, this operation is referred to as operation H in this embodiment of the application.

[0209] If cell-level discontinuous transmission of the first serving cell has been activated, and the first serving cell is not in the active period of cell-level discontinuous transmission, the first low-power wake-up signal is sent according to the configuration information of the low-power wake-up signal; for ease of description, this operation is referred to as operation I in this embodiment of the application.

[0210] If cell-level discontinuous transmission of the first serving cell has been activated, the first low-power wake-up signal is sent according to the configuration information of the low-power wake-up signal; for ease of description, this operation is referred to as operation J in this embodiment.

[0211] In this embodiment of the application, in the above operations F, G and H, the first serving cell sends WUS to terminals with service needs during the Cell-DTX activity period, and the terminal only monitors WUS during the Cell-DTX activity period; once the terminal detects WUS, it triggers the terminal to monitor the Physical Downlink Control Channel (PDCCH), and energy saving can be achieved on both the terminal side and the network side.

[0212] In this embodiment of the application, in the above operations I and J, the first serving cell can more flexibly choose when to send LP-WUS, which can realize network-side energy saving; while the terminal needs to monitor LP-WUS during the active or inactive period of Cell-DTX, which can reduce the latency of service scheduling transmission.

[0213] In an optional embodiment of this application, operation I includes:

[0214] If cell-level discontinuous transmission of the first serving cell has been activated, and the first serving cell is not in the active period of cell-level discontinuous transmission, the first low-power wake-up signal is sent according to the configuration information of the low-power wake-up signal if the first condition is met.

[0215] The first condition includes at least one of the following:

[0216] The first serving cell has a running first timer in any of the discontinuous transmission groups to which it belongs;

[0217] The terminal sends a scheduling request to the first serving cell via the physical uplink control channel, and the scheduling request is in a pending state.

[0218] Multicast service is configured on any of the serving cells in the discontinuous transmission group to which the first serving cell belongs;

[0219] Multicast service is configured on the primary cell in the discontinuous transmission group to which the first serving cell belongs;

[0220] The first timer includes at least one of the following: uplink retransmission timer for discontinuous transmission (drx-RetransmissionTimerUL), downlink retransmission timer for discontinuous transmission (drx-RetransmissionTimerDL), and pass-through retransmission timer for discontinuous transmission (drx-RetransmissionTimerSL).

[0221] In an optional embodiment of this application, the above operation J includes:

[0222] If cell-level discontinuous transmission of the first serving cell is activated, the first low-power wake-up signal is sent according to the configuration information of the low-power wake-up signal, provided that the second condition is met; the second condition includes at least one of the following:

[0223] The first serving cell has a running first timer in any of the discontinuous transmission groups to which it belongs;

[0224] The terminal sends a scheduling request to the first serving cell via the physical uplink control channel, and the scheduling request is in a pending state.

[0225] Multicast service is configured on any of the serving cells in the discontinuous transmission group to which the first serving cell belongs;

[0226] Multicast service is configured on the primary cell in the discontinuous transmission group to which the first serving cell belongs;

[0227] The first timer includes at least one of the following: uplink retransmission timer for discontinuous transmission (drx-RetransmissionTimerUL), downlink retransmission timer for discontinuous transmission (drx-RetransmissionTimerDL), and pass-through retransmission timer for discontinuous transmission (drx-RetransmissionTimerSL).

[0228] Based on Operation I or Operation J, in order to further help the network save energy, this application embodiment points out that the first serving cell will send WUS only when the first condition or the second condition is met, regardless of whether the Cell-DTX is active or inactive; if the first condition or the second condition is not met, the first serving cell will not send WUS during the inactive period of the Cell-DTX.

[0229] In summary, in this embodiment of the application, when the first low-power wake-up signal is monitored and cell-level discontinuous transmission is configured in the first serving cell, the operation on the network side is limited, thereby achieving the goal of balancing the energy saving of the terminal and the energy saving of the first serving cell.

[0230] To more clearly describe the energy-saving method provided in the embodiments of this application, an example is given below.

[0231] Example 1

[0232] When a serving cell has both LP-WUS monitoring and Cell-DTX configured / activated, the terminal's behavior in monitoring LP-WUS will differ depending on the LP-WUS configuration and / or the different PDCCH monitoring physical processes triggered by LP-WUS. For example:

[0233] LP-WUS-triggered PDCCH monitoring scheme 1-1: When using LP-WUS to achieve a function similar to DCI with PS-RNTI scrambling (DCP), that is, the monitoring timing of LP-WUS is configured before drx-onDurationTimer (DRX duration timer), during the monitoring timing of LP-WUS,

[0234] If LP-WUS is detected, MR will be triggered to start drx-onDurationTimer;

[0235] If LP-WUS is not detected, MR startup drx-onDurationTimer will not be triggered.

[0236] Regarding the LP-WUS-triggered PDCCH monitoring scheme 1-1, the terminal's behavior in monitoring LP-WUS on the serving cell with Cell-DTX configured / activated is as follows:

[0237] When the serving cell is not in a Cell-DTX active period or is in a Cell-DTX inactive period; or regardless of whether the serving cell is in a Cell-DTX active period, the terminal needs to monitor LP-WUS configured / activated on this serving cell, that is, Cell-DTX has no impact on whether and when the terminal monitors LP-WUS. Or,

[0238] When the serving cell is in the Cell-DTX active period or not in the Cell-DTX inactive period, the terminal monitors LP-WUS during the Cell-DTX active period. That is, the timing of LP-WUS monitoring or LP-WUS resources are available and effective during the Cell-DTX active period.

[0239] LP-WUS-triggered PDCCH monitoring scheme 1-2: Based on the LP-WUS monitoring configuration, LP-WUS monitoring should be performed at least outside of traditional C-DRX (Connected Discontinuous Reception) activity periods or during traditional C-DRX inactivity periods to trigger PDCCH monitoring. For example:

[0240] In addition to PDCCH monitoring triggered by the traditional C-DRX cycle and drx-onDurationTimer, LP-WUS can also trigger PDCCH monitoring outside of drx-onDurationTimer or during C-DRX inactivity periods. Alternatively,

[0241] Traditional C-DRX cycles and drx-onDurationTimer do not trigger PDCCH monitoring, while LP-WUS triggers PDCCH monitoring.

[0242] For the LP-WUS-triggered PDCCH monitoring scheme 1-2, the terminal's LP-WUS monitoring behavior on the serving cell with Cell-DTX configured / activated is at least one of the following:

[0243] If Cell-DTX operation of this serving cell has been disabled / deactivated, the terminal will monitor LP-WUS according to the LP-WUS configuration information on the serving cell. That is, deactivated Cell-DTX will not change the monitoring timing of LP-WUS or the effectiveness and availability of LP-WUS resources.

[0244] If the serving cell is in the Cell-DTX active period or the serving cell is not in the Cell-DTX inactive period, the terminal monitors LP-WUS during the Cell-DTX active period. That is, the timing of LP-WUS monitoring or LP-WUS resources are available and effective during the Cell-DTX active period.

[0245] If Cell-DTX operation is activated and the serving cell is not in a Cell-DTX active period or is in a Cell-DTX inactive period, the terminal does not need or require the terminal, or this depends on the terminal's implementation, or the terminal does not expect to monitor LP-WUS configured / activated on this serving cell during Cell-DTX inactive periods. In other words, the timing of LP-WUS monitoring or LP-WUS resources are unavailable and invalid during Cell-DTX inactive periods.

[0246] LP-WUS-triggered PDCCH monitoring scheme 1-3: Based on the LP-WUS monitoring configuration, LP-WUS monitoring will be performed at least during the traditional C-DRX activity period to trigger PDCCH monitoring. That is, only when WUS is detected during the C-DRX activity period will MR start PDCCH monitoring.

[0247] For the LP-WUS-triggered PDCCH monitoring schemes 1-3, the terminal's LP-WUS monitoring behavior on the serving cell with Cell-DTX configured / activated is at least one of the following:

[0248] If Cell-DTX operation of this serving cell has been disabled / deactivated, the terminal will monitor LP-WUS according to the LP-WUS configuration information on the serving cell. That is, deactivated Cell-DTX will not change the monitoring timing of LP-WUS or the effectiveness and availability of LP-WUS resources.

[0249] If the serving cell is in the Cell-DTX active period or not in the Cell-DTX inactive period, the terminal monitors LP-WUS during the Cell-DTX active period. That is, the timing of LP-WUS monitoring or LP-WUS resources are available and effective during the Cell-DTX active period.

[0250] If Cell-DTX operation is activated and the serving cell is not in a Cell-DTX active period or is in a Cell-DTX inactive period, the terminal does not need or require the terminal, or this depends on the terminal's implementation, or the terminal does not expect to monitor LP-WUS configured / activated on this serving cell during Cell-DTX inactive periods. In other words, the timing of LP-WUS monitoring or LP-WUS resources are unavailable and invalid during Cell-DTX inactive periods.

[0251] As shown in Figure 4, this application embodiment also provides an energy-saving method, which includes:

[0252] When a second low-power wake-up signal, configured or indicated by the network, is applied to the second serving cell, and the second serving cell is configured or has activated cell-level discontinuous transmission, the terminal performs at least one of the following operations:

[0253] If the terminal detects the second low-power wake-up signal, it applies the configuration information of the second low-power wake-up signal during the active period of cell-level discontinuous transmission in the second serving cell; for ease of description, this operation is referred to as operation K in this embodiment.

[0254] If the terminal does not detect the second low-power wake-up signal during the active period of cell-level discontinuous transmission in the second serving cell, the configuration information of the cell-level discontinuous transmission is applied during the active period of cell-level discontinuous transmission in the second serving cell; for ease of description, this operation is referred to as operation L in this embodiment.

[0255] If the second low-power wake-up signal is detected during the inactivity period of cell-level discontinuous transmission in the second serving cell, the terminal ignores the second low-power wake-up signal; for ease of description, this operation is referred to as operation M in this embodiment of the application.

[0256] If the terminal detects the second low-power wake-up signal, it applies the configuration information of the second low-power wake-up signal; for ease of description, this operation is referred to as operation N in this embodiment.

[0257] In this embodiment of the application, when a second low-power wake-up signal configured or indicated by the network acts on the second serving cell, and the second serving cell configures or activates cell-level discontinuous transmission, the operation of the terminal is limited, thereby achieving the goal of balancing the energy saving of the terminal and the energy saving of the second serving cell.

[0258] Optionally, the phrases "the second serving cell is in an inactive period of cell-level discontinuous transmission" and "the second serving cell is not in an active period of cell-level discontinuous transmission" mentioned in the embodiments of this application can also be referred to as "active period" and "inactive period" can also be referred to as "inactive time". No specific limitation is made here.

[0259] As an optional embodiment, the above operation K includes:

[0260] If the terminal detects the second low-power wake-up signal at the first moment, it applies the configuration information of the second low-power wake-up signal during the active period of cell-level discontinuous transmission (such as Cell-DTX or Cell-DRX) of the second serving cell.

[0261] Wherein, the time length between the first moment and the active period of cell-level discontinuous transmission is less than a preset value, or, the first moment is within the active period of the cell-level discontinuous transmission.

[0262] In an optional embodiment of this application, the configuration information for applying the second low-power wake-up signal includes:

[0263] Based on the configuration information of the second low-power wake-up signal, monitor the physical downlink control channel (PDCCH), and / or enable a duration timer for discontinuous transmission, and / or enable a second timer; the second timer is a timer for activating or deactivating the low-power wake-up signal.

[0264] In another optional embodiment of this application, the configuration information for applying the cell-level discontinuous transmission includes:

[0265] Based on the configuration information of the cell-level discontinuous transmission, monitor the physical downlink control channel (PDCCH) and / or start a timer for the duration of discontinuous transmission.

[0266] Alternatively, the above operation K can also be expressed as:

[0267] If the terminal detects a low-power wake-up signal (such as LP-WUS) at the position closest in time to the current or next Cell-DTX active period, the terminal, according to the LP-WUS configuration information, monitors the PDCCH, enables drx-onDurationTimer, or enables at least one of the following new timers introduced to activate / deactivate LP-WUS during the active period of the second serving cell cell-DTX:

[0268] Alternatively, if the terminal detects LP-WUS operating on the second serving cell during the Cell-DTX activity period of the second serving cell, the terminal, based on the LP-WUS configuration information, monitors the PDCCH, enables drx-onDurationTimer, or enables at least one of the following new timers introduced to activate / deactivate LP-WUS during the Cell-DTX activity period of the second serving cell:

[0269] Alternatively, the above operation L can also be expressed as:

[0270] If the terminal does not detect LP-WUS operating on the second serving cell during the Cell-DTX activity period of the second serving cell, the terminal will monitor the PDCCH according to the Cell-DTX configuration information during the Cell-DTX activity period of the second serving cell.

[0271] Alternatively, the above operation M can also be expressed as:

[0272] If the terminal detects LP-WUS operating on the second serving cell during the inactivity period of Cell-DTX in the second serving cell, the terminal ignores the effect of LP-WUS on the second serving cell, or in other words, the terminal ignores the indication information of LP-WUS on the second serving cell. That is, the terminal does not need or require the terminal, or it depends on the terminal's implementation, or the terminal does not expect to apply LP-WUS during the inactivity period of Cell-DTX in the second serving cell; or it can be understood that LP-WUS does not operate during the inactivity period of Cell-DTX in a serving cell.

[0273] It should be noted that among the above operations K, L, and M, the network side has more flexibility in configuring WUS (such as which cell WUS is effective in) and transmitting WUS (such as the transmission time of WUS and on which cell it is transmitted); and it can achieve energy saving on the terminal side. The WUS detected by the terminal is only effective during the Cell-DTX activity period, so the network can only schedule the terminal's services during the Cell-DTX activity period.

[0274] Alternatively, the above operation N can also be expressed as:

[0275] The terminal only activates the drx-onDurationTimer or a new timer introduced to activate / deactivate LP-WUS and / or monitors the PDCCH based on the detected LP-WUS acting on the second serving cell. That is, the Cell-DTX of the second serving cell has no effect on LP-WUS triggering to activate the drx-onDurationTimer or a new timer introduced to activate / deactivate LP-WUS and / or monitor the PDCCH for that serving cell; it can also be described as: once LP-WUS acting on the second serving cell is detected, the terminal will start monitoring the PDCCH of that serving cell, even if LP-WUS is detected during the inactivity period of the Cell-DTX of the second serving cell.

[0276] In this operation N, the network side has more flexibility in configuring WUS (such as which cell WUS is active in) and sending WUS (such as the sending time of WUS and on which cell it is sent), and reduces the latency of service scheduling for the terminal.

[0277] In summary, in the embodiments of this application, when the second low-power wake-up signal configured or indicated by the network acts on the second serving cell, and the second serving cell configures or activates cell-level discontinuous transmission, the operation of the terminal is limited, thereby achieving the goal of balancing the energy saving of the terminal and the energy saving of the second serving cell.

[0278] As shown in Figure 5, this application embodiment also provides an energy-saving method, which includes:

[0279] Step 501: When a second low-power wake-up signal, configured or indicated by the network, is applied to the second serving cell, and the second serving cell has configured or activated cell-level discontinuous transmission, the network-side device of the second serving cell performs at least one of the following operations:

[0280] According to the configuration information of the second low-power wake-up signal, send the second low-power wake-up signal;

[0281] During the active period of cell-level discontinuous transmission in the second serving cell, the second low-power wake-up signal is sent according to the configuration information of the second low-power wake-up signal.

[0282] During the inactivity period of cell-level discontinuous transmission in the second serving cell, the second low-power wake-up signal is sent according to the configuration information of the second low-power wake-up signal.

[0283] In this embodiment, the second serving cell may send a low-power wake-up signal only based on the configuration information of the low-power wake-up signal, i.e., the second serving cell does not consider the configured or activated cell-level discontinuous transmission; or, the second serving cell needs to consider the configuration of cell-level discontinuous transmission when sending the low-power wake-up signal, i.e., the second serving cell only sends the low-power wake-up signal during the active period of the cell-level discontinuous configuration; or, the second serving cell also sends the low-power wake-up signal during the inactive period of the cell-level discontinuous configuration; correspondingly, the terminal monitors the wake-up signal according to the configuration information of the low-power wake-up signal, at the monitoring timing of the low-power wake-up signal or on the low-power wake-up signal resources; or, during the active period of the cell-level discontinuous transmission of the second serving cell, the terminal monitors the wake-up signal according to the configuration information of the low-power wake-up signal; or, during the inactive period of the cell-level discontinuous transmission of the second serving cell, the terminal monitors the wake-up signal according to the configuration information of the low-power wake-up signal.

[0284] In this embodiment of the application, the above-mentioned energy-saving method makes the network side's configuration of WUS (such as which cell WUS is effective in) and transmission of WUS (such as the transmission time of WUS and on which cell it is transmitted) more flexible, thereby enabling network-side energy saving.

[0285] In summary, in the embodiments of this application, when the second low-power wake-up signal configured or indicated by the network acts on the second serving cell, and the second serving cell configures or activates cell-level discontinuous transmission, the operation on the network side is limited, thereby achieving the goal of balancing the energy saving of the terminal and the energy saving of the second serving cell.

[0286] To more clearly describe the energy-saving method provided in the embodiments of this application, an example is given below.

[0287] Example 2

[0288] When the network configures / instructs LP-WUS to operate on a serving cell that has Cell-DTX configured / activated, and the terminal detects LP-WUS operating on that serving cell, depending on the different LP-WUS configurations and / or the different PDCCH monitoring physical processes triggered by the LP-WUS, the effectiveness of LP-WUS on serving cells with Cell-DTX configured / activated may also vary. For example:

[0289] LP-WUS-triggered PDCCH monitoring scheme 1-1: When using LP-WUS to achieve a function similar to R16 DCP, that is, the LP-WUS monitoring timing is configured before drx-onDurationTimer, during the LP-WUS monitoring timing,

[0290] If LP-WUS is detected, MR will be triggered to start drx-onDurationTimer;

[0291] If LP-WUS is not detected, MR startup drx-onDurationTimer will not be triggered.

[0292] Regarding the LP-WUS-triggered PDCCH monitoring scheme 1-1, the terminal's application of LP-WUS on the serving cell where Cell-DTX is configured / activated is that the UE only enables drx-onDurationTimer or enables a new timer introduced to activate / deactivate LP-WUS based on the detected LP-WUS acting on the serving cell. That is, Cell-DTX of the serving cell has no effect on enabling drx-onDurationTimer or enabling a new timer introduced to activate / deactivate LP-WUS on the serving cell due to LP-WUS triggering.

[0293] LP-WUS Triggered PDCCH Monitoring Scheme 1-2: Based on the LP-WUS monitoring configuration, LP-WUS monitoring should be performed at least outside of traditional C-DRX active periods or during traditional C-DRX inactive periods to trigger PDCCH monitoring. For example,

[0294] In addition to PDCCH monitoring triggered by the traditional C-DRX cycle and drx-onDurationTimer, LP-WUS can also trigger PDCCH monitoring outside of drx-onDurationTimer or during C-DRX inactivity periods. Alternatively,

[0295] Traditional C-DRX cycles and drx-onDurationTimer do not trigger PDCCH monitoring, while LP-WUS triggers PDCCH monitoring.

[0296] LP-WUS-triggered PDCCH monitoring scheme 1-3: Based on the LP-WUS monitoring configuration, LP-WUS monitoring will be performed at least during the traditional C-DRX activity period to trigger PDCCH monitoring. That is, only when WUS is detected during the C-DRX activity period will MR start PDCCH monitoring.

[0297] For the LP-WUS-triggered PDCCH monitoring schemes 1-2 and / or 1-3, the terminal's LP-WUS application behavior on the serving cell with Cell-DTX configured / activated can be at least one of the following:

[0298] 1. If, during the Cell-DTX activity period of the serving cell, the terminal detects LP-WUS operating on the serving cell, then during the Cell-DTX activity period of the serving cell, the terminal monitors the PDCCH according to at least one of the Cell-DTX PDCCH monitoring rules and the LP-WUS PDCCH monitoring rules, including at least one of the following:

[0299] The terminal is required to monitor only the PDCCHs specified by Cell-DTX.

[0300] The terminal is required to monitor only the PDCCHs specified by LP-WUS.

[0301] The PDCCHs that are not required to be monitored by the terminal only include those PDCCHs that Cell-DTX specifies as not to be monitored;

[0302] The PDCCHs that are not required to be monitored by the terminal only include those PDCCHs that are not monitored as specified by LP-WUS;

[0303] The PDCCH that the terminal is required to monitor includes the union or intersection of the PDCCHs monitored by Cell-DTX and the PDCCHs monitored by LP-WUS.

[0304] The PDCCHs that are not required to be monitored by the terminal include the union or intersection of those PDCCHs that Cell-DTX specifies not to monitor and those PDCCHs that LP-WUS specifies not to monitor;

[0305] 2. If the terminal does not detect LP-WUS operating on the serving cell during the Cell-DTX activity period, the terminal will monitor the PDCCH according to the Cell-DTX PDCCH monitoring rules during the Cell-DTX activity period.

[0306] 3. If the terminal detects LP-WUS acting on the serving cell during the inactivity period of Cell-DTX of the serving cell, the terminal ignores the effect of LP-WUS on the serving cell, or the terminal does not need or require the terminal, or it depends on the implementation of the terminal, or the terminal does not expect to apply LP-WUS during the inactivity period of Cell-DTX of the serving cell.

[0307] This application also provides an energy-saving method, including at least one of the following:

[0308] The first device does not expect to configure or activate monitoring resources for low-power wake-up signals on serving cells where cell-level discontinuous transmission is configured or activated.

[0309] In a serving cell configured with cell-level discontinuous transmission and low-power wake-up signal monitoring, if the cell-level discontinuous transmission of the serving cell is deactivated, the first device determines to activate the monitoring of the low-power wake-up signal on the serving cell.

[0310] In a serving cell configured with cell-level discontinuous transmission and low-power wake-up signal monitoring, if cell-level discontinuous transmission is activated in the serving cell, the first device determines to deactivate the monitoring of low-power wake-up signal on the serving cell.

[0311] In a serving cell configured with cell-level discontinuous transmission and low-power wake-up signal monitoring, if the low-power wake-up signal is activated on the serving cell, the first device determines to deactivate the cell-level discontinuous transmission on the serving cell.

[0312] In a serving cell configured with cell-level discontinuous transmission and low-power wake-up signal monitoring, if the low-power wake-up signal on the serving cell is deactivated, the first device determines to activate cell-level discontinuous transmission on the serving cell.

[0313] The first device is either a terminal or a network-side device.

[0314] In summary, to simplify operation, the embodiments of this application limit that LP-WUS (Low Power Wake-up Signal) monitoring and Cell-DTX (Cell Discontinuous Transmission) can not be activated simultaneously on a serving cell.

[0315] This application embodiment also provides an energy-saving method, the method comprising:

[0316] In the case where low-power wake-up signal monitoring and cell-level discontinuous transmission are configured in the third serving cell, if the terminal detects the low-power wake-up signal in the third serving cell, the terminal performs at least one of the following operations:

[0317] Start the duration timer for cell-level discontinuous transmission in the current cycle or the next cycle of the third serving cell;

[0318] Ignore the configuration information of cell-level discontinuous transmission in the current cycle or the next cycle of the third serving cell.

[0319] For example, the terminal ignores the configuration information of cell-level discontinuous transmission in the current period of the third serving cell and starts a timer for the duration of cell-level discontinuous transmission in the next period of the third serving cell.

[0320] For example, the terminal starts a timer for the duration of cell-level discontinuous transmission in the current cycle or the next cycle of the third serving cell;

[0321] For example, the terminal ignores the configuration information of cell-level discontinuous transmission in the current cycle or the next cycle of the third serving cell.

[0322] In summary, to simplify operation and achieve certain network and terminal energy-saving effects, the monitoring of LP-WUS (Low Power Wake-up Signal) and the interoperability of Cell-DTX / DRX (Cell-level Discontinuous Transmission) in a serving cell include at least one of the following:

[0323] When a terminal detects LP-WUS in a serving cell, the celldtxdrx-onDurationTimer (duration timer) for the current or next cycle of cell-DTX / DRX in that serving cell is activated;

[0324] When a terminal detects LP-WUS in a serving cell, the cell-DTX / DRX of that serving cell will not be effective in the current or next cycle; that is, the cell is in an active period in the current and / or next cycle of cell-DTX / DRX, and there is no inactive period.

[0325] This application also provides an energy-saving method, including at least one of the following:

[0326] The second device does not expect to configure or activate a low-power wake-up signal acting on the serving cell on a serving cell where cell-level discontinuous transmission is configured or activated.

[0327] On a serving cell where cell-level discontinuous transmission is configured or activated, the second device ignores the low-power wake-up signal acting on the serving cell.

[0328] When cell-level discontinuous transmission and low-power wake-up signal acting on the serving cell are configured on the serving cell, if cell-level discontinuous transmission on the serving cell is deactivated, the second device determines to activate the low-power wake-up signal acting on the serving cell.

[0329] When cell-level discontinuous transmission and low-power wake-up signal acting on the serving cell are configured on the serving cell, if cell-level discontinuous transmission on the serving cell is activated, the second device determines to deactivate the low-power wake-up signal acting on the serving cell.

[0330] When cell-level discontinuous transmission and a low-power wake-up signal acting on the serving cell are configured on the serving cell, if the low-power wake-up signal acting on the serving cell is activated, the second device determines that the cell-level discontinuous transmission on the serving cell is deactivated.

[0331] When cell-level discontinuous transmission and a low-power wake-up signal acting on the serving cell are configured on the serving cell, if the low-power wake-up signal acting on the serving cell is deactivated, the second device determines that cell-level discontinuous transmission on the serving cell is activated.

[0332] The second device is either a terminal or a network-side device.

[0333] In summary, to simplify operation, the embodiments of this application limit that Cell-DTX (cell-level discontinuous transmission) cannot be activated and LP-WUS (low-power wake-up signal) can be configured or indicated to be applied to the serving cell at the same time.

[0334] This application embodiment also provides an energy-saving method, the method comprising:

[0335] When a network configuration or indication of a low-power wake-up signal is applied to a fourth serving cell, and the fourth serving cell is configured or has activated cell-level discontinuous transmission, if the terminal detects a low-power wake-up signal applied to the fourth serving cell, the terminal performs at least one of the following operations:

[0336] Start the duration timer for cell-level discontinuous transmission in the current cycle or the next cycle of the fourth serving cell;

[0337] Ignore the configuration information of cell-level discontinuous transmission in the current period or the next period of the fourth serving cell.

[0338] For example, the terminal ignores the configuration information of cell-level discontinuous transmission in the current cycle of the fourth serving cell and starts a timer for the duration of cell-level discontinuous transmission in the next cycle of the fourth serving cell.

[0339] For example, the terminal starts a timer for the duration of cell-level discontinuous transmission in the current cycle or the next cycle of the fourth serving cell;

[0340] For example, the terminal ignores the configuration information of cell-level discontinuous transmission in the current cycle or the next cycle of the fourth serving cell.

[0341] In summary, to simplify operation and achieve certain network and terminal energy-saving effects, the application of LP-WUS (Low Power Wake-up Signal) to a serving cell and the interoperability of that serving cell's Cell-DTX / DRX (Cell-level Discontinuous Transmission) may also include at least one of the following:

[0342] When a terminal detects LP-WUS acting on a serving cell, the celldtxdrx-onDurationTimer (duration timer) for the current or next cycle of cell-DTX / DRX in that serving cell is activated;

[0343] When a terminal detects LP-WUS acting on a serving cell, cell-DTX / DRX of that serving cell will not be effective in the current or next cycle; that is, the cell will be active in the current and / or next cycle of cell-DTX / DRX, with no inactive period.

[0344] To more clearly describe the energy-saving method provided in the embodiments of this application, two examples are given below.

[0345] Example 3

[0346] As shown in Figure 6, serving cell #1 (Cell #1) monitored by LP-WUS did not have Cell-DTX configured or activated, while serving cell #2 (Cell #2) where LP-WUS was active or effective had Cell-DTX configured / activated.

[0347] WUS monitoring opportunity #2 is the WUS closest in time to the current or next Cell-DTX activity period, therefore the UE monitors WUS during WUS monitoring opportunity #2.

[0348] If WUS is detected, the terminal enables drx-onDurationTimer and / or monitors PDCCH during the current or next cell-DTX activity period of cell#2;

[0349] If WUS is not detected, the terminal will not enable drx-onDurationTimer and / or will not monitor PDCCH during the current or next cell-DTX activity period of cell#2.

[0350] Example 4

[0351] LP-WUS serving cell #1 has Cell-DTX configured / activated, while LP-WUS-enabled serving cell #2 has not.

[0352] As shown in Figure 7, the terminal monitors WUS during the Cell-DTX activation time on cell #1 where Cell-DTX is activated. If WUS is detected, the terminal enables drx-onDurationTimer and / or monitors PDCCH on cell #2; if WUS is not detected, the terminal does not enable drx-onDurationTimer and / or does not monitor PDCCH on cell #2.

[0353] As shown in Figure 8, the terminal monitors WUS on cell #1 where Cell-DTX is configured and activated, and Cell-DTX on cell #1 has no impact on WUS monitoring. The terminal monitors WUS at the times when WUS monitoring is configured.

[0354] If WUS is detected, the terminal enables drx-onDurationTimer and / or monitors PDCCH on cell #2;

[0355] If WUS is not detected, the terminal will not enable drx-onDurationTimer and / or will not monitor PDCCH on cell#2.

[0356] Example 5

[0357] If the serving cell #1 that monitors LP-WUS has configured / activated Cell-DTX, the associated serving cell #2 that has LP-WUS in effect also needs to configure / activate Cell-DTX, and the network guarantees that the Cell-DTX of serving cell #1 and the Cell-DTX of serving cell #2 have partially or completely overlapping Cell active time.

[0358] For example, as shown in Figure 9, the Cell-DTX of serving cell #1 and the Cell-DTX of serving cell #2 have some overlap in Cell active time. The terminal monitors LP-WUS during the active period of Cell-DTX of serving cell #1.

[0359] If the serving cell #1, which is active / effective for LP-WUS, has configured / activated Cell-DTX, the associated serving cell #2, which monitors LP-WUS, also needs to configure / activate Cell-DTX, and the network guarantees that the Cell active time of the serving cell #1's Cell-DTX and the serving cell #2's Cell-DTX partially or completely overlaps.

[0360] For example, as shown in Figure 10, the Cell-DTX of serving cell #1 and the Cell-DTX of serving cell #2 have completely overlapping Cell active times. LP-WUS is monitored during the inactive period of Cell-DTX in serving cell #1, or Cell-DTX does not affect LP-WUS monitoring. The terminal monitors WUS.

[0361] If WUS is detected, the terminal enables drx-onDurationTimer and / or monitors PDCCH during the current or next cell-DTX activity period of cell#2;

[0362] If WUS is not detected, the terminal will not enable drx-onDurationTimer and / or will not monitor PDCCH during the current or next cell-DTX activity period of cell#2.

[0363] Example 6

[0364] If a WUS transmitted on an LP-WUS monitoring cell can affect M cells (M>1), then the WUS monitors the WUS on the intersection or union of the cell-DTX active periods of these M affected cells and the LP-WUS monitoring cell. If a cell is not configured with cell-DTX, then all time periods of this cell are considered to be active periods. For example...

[0365] For example, cell 1 is the LP-WUS monitoring cell. Cell 2 is the cell that the LP-WUS is active in; time slots 5-9 of cell 1 are the cell-DTX active period, and time slots 0-8 of cell 2 are the cell-DTX active period. Therefore, the union of these two cell-DTX active periods, that is, time slots 0-9, can be monitored by LP-WUS.

[0366] For example, cell 1 is the LP-WUS monitoring cell. Cells 2 and 3 are the cells that function with this LP-WUS. Time slots 0-8 of cell 1 are the cell-DTX activity period, time slots 0-2 of cell 2 are the cell-DTX activity period, and time slots 0-4 of cell 3 are the cell-DTX activity period. Therefore, the union of the cell-DTX activity periods of these two WUS-functioning cells, cell 2 and cell 3, means that LP-WUS can be monitored in time slots 0-4.

[0367] The energy-saving method provided in this application can be implemented by an energy-saving device. This application uses an energy-saving device to implement the energy-saving method as an example to illustrate the energy-saving device provided in this application.

[0391] In this embodiment of the application, when the first low-power wake-up signal is monitored and cell-level discontinuous transmission is configured in the first serving cell, the operation of the terminal is limited, thereby achieving the goal of balancing the energy saving of the terminal and the energy saving of the first serving cell.

[0392] It should be noted that the energy-saving device provided in this application embodiment is a device capable of performing the above-described energy-saving method. Therefore, all embodiments of the above-described energy-saving method are applicable to this device and can achieve the same or similar beneficial effects. No further limitation is made here.
