[0135] In the embodiments of the present disclosure, after the terminal receives the cell DTX configuration, it can determine each cell DTX configuration, and further determine whether the subsequent cell DTX configuration is activated.

[0136] In step S2103, the cell DTX configuration of the first cell of the terminal is activated.

[0137] In the embodiments of the present disclosure, the terminal can determine that the cell DTX configuration is activated, and further perform the step of determining whether to transmit the first wake-up signal based on the activated cell DTX configuration.

[0138] In some embodiments, the first cell is configured to transmit the first wake-up signal. Alternatively, it can also be understood that the first cell is a cell configured to transmit the first wake-up signal.

[0139] In some embodiments, the first wake-up signal is a low-power wake-up signal (LP WUS) or other signals, which are not limited in the embodiments of the present disclosure.

[0140] In some embodiments, the first wake-up signal is configured to indicate whether the terminal wakes up on one or more cells. For example, the first wake-up signal is configured to indicate that the terminal wakes up on cell A. Alternatively, the first wake-up signal is configured to indicate that the terminal wakes up on cell A and cell B. Alternatively, other cases are not limited in the embodiments of the present disclosure.

[0141] In some embodiments, the network device transmits activation signaling to the terminal, and the terminal activates the cell DTX configuration after receiving the activation signaling. Alternatively, the activation signaling is a MAC CE (Media Access Control Control Element) or a DCI (Downlink Control Information), or other signaling, which are not limited in the embodiments of the present disclosure. Alternatively, the DCI is a DCI 2-9 or other DCI, which are not limited in the embodiments of the present disclosure.

[0142] In some embodiments, the terminal activates the cell DTX configuration after receiving the configuration of the cell DTX.

[0143] Alternatively, the activation signaling is configured to activate the first cell, and is also configured to activate the cell DTX configuration of other cells, which are not limited in the embodiments of the present disclosure.

[0144] In step S2104, the network device determines whether to transmit the first wake-up signal based on the cell DTX configuration of the terminal.

[0145] In the embodiments of the present disclosure, after the cell DTX configuration is activated, the terminal can determine that there are active time periods and non-active time periods. The terminal needs to determine whether to transmit the first wake-up signal based on the active time periods and non-active time periods included in the cell DTX configuration.

[0146] In some embodiments, the network device determines whether to transmit the first wake-up signal based on the activation state of the cell DTX configuration. Alternatively, the activation state of the cell DTX configuration includes two states: activated and unactivated.

[0147] In some embodiments, the first cell of the terminal is in a cell DTX configuration, and the first wake-up signal is transmitted in an active period of the cell DTX configuration. In the embodiments of the present disclosure, the active period of the cell DTX configuration is used to indicate that the terminal can perform normal reception and transmission operations, and thus the network device can transmit the first wake-up signal in the active period of the cell DTX configuration.

[0148] In some embodiments, the first cell of the terminal is in a cell DTX configuration, and the first wake-up signal is transmitted in an inactive period of the cell DTX configuration. In the embodiments of the present disclosure, the network device can ignore the inactive period included in the cell DTX configuration, and the network device can normally transmit the first wake-up signal.

[0149] In some embodiments, the first wake-up signal is transmitted when the first cell of the terminal is not in a cell DTX configuration. In the embodiments of the present disclosure, when the first cell of the terminal is not in a cell DTX configuration, it indicates that the terminal does not have a reception failure, and thus the network device can transmit the first wake-up signal.

[0150] In some embodiments, the first wake-up signal is not transmitted in an inactive period of the cell DTX configuration. In the embodiments of the present disclosure, when the first wake-up signal is not transmitted in the inactive period of the cell DTX configuration, it indicates that the terminal cannot normally perform reception and transmission operations, and thus the network device does not transmit the first wake-up signal.

[0151] In step S2105, the terminal determines reception / listening of the first wake-up signal based on the cell DTX configuration.

[0152] In the embodiments of the present disclosure, the active period and the inactive period included in the cell DTX configuration affect the reception and transmission operations of the terminal, and thus the terminal needs to determine reception / listening of the first wake-up signal based on the cell DTX configuration.

[0153] In some embodiments, the terminal receives or listens to the first wake-up signal based on an active state of the cell DTX configuration.

[0154] In some embodiments, the first cell of the terminal is in a cell DTX configuration, and the first wake-up signal is received / listened to in an active period of the cell DTX configuration. In the embodiments of the present disclosure, the terminal can normally perform reception and transmission operations in the active period of the cell DTX configuration, and thus the terminal can normally receive / listen to the first wake-up signal in the active period of the cell DTX configuration.

[0155] In some embodiments, the cell DTX configuration of the first cell of the terminal is activated, and the first wake-up signal is received / listened to in the non-activation period of the cell DTX configuration. In the embodiments of the present disclosure, the terminal can ignore the non-activation period of the cell DTX configuration, and can normally listen to the first wake-up signal in the non-activation period.

[0156] It should be noted that the embodiments of the present disclosure are described by taking the activation of the cell DTX configuration as an example. In another embodiment, there is also a non-activation case. Alternatively, the cell DTX configuration of the first cell of the terminal is not activated, and the first wake-up signal is received / listened to. In the embodiments of the present disclosure, if the cell DTX configuration of the first cell of the terminal is not activated, it means that the terminal will not be affected by the non-activation period of the cell DTX configuration, and thus can normally receive / listen to the first wake-up signal.

[0157] In some embodiments, the cell DTX configuration of the first cell is not activated, including at least one of the following:

[0158] (1) The first cell is not configured with the cell DTX configuration.

[0159] In the embodiments of the present disclosure, if the first cell is not configured with the cell DTX configuration, it means that the terminal also does not activate the cell DTX configuration of the first cell, and thus the cell DTX configuration of the first cell of the terminal is not activated.

[0160] (2) The first cell is configured with the cell DTX configuration, but the cell DTX configuration is not activated by using the activation information.

[0161] In the embodiments of the present disclosure, after the terminal is configured with the cell DTX configuration, the terminal also needs to activate the cell DTX configuration by using the activation information. If the terminal does not receive the activation information, it means that the cell DTX configuration of the first cell of the terminal is not activated.

[0162] Alternatively, the activation information is DCI or MAC CE.

[0163] (3) The first cell is configured with the cell DTX configuration, and the cell DTX configuration is activated by using the activation information, but the activation information does not reach the effective time of the cell DTX configuration.

[0164] In the embodiments of the present disclosure, after the terminal receives the activation information, the effective time of the activation information is after the receiving time of the activation information. If the terminal receives the activation information, but the activation information does not take effect, the cell DTX configuration of the first cell is not activated at this time.

[0165] Optionally, the activation information takes effect x time slots / symbols after the time of receiving the activation information, where x is a positive integer.

[0166] In some embodiments, the cell DTX configuration can be configured separately for each carrier, and the SCS of the activated BWP on each carrier can be the same or different for the terminal. For example, the terminal has 4 serving carriers, which are cell 1, cell 2, cell 3, and cell 4, respectively. The SCS of the activated BWP on different carriers can be different, for example, SCS = 30 kHz (kilohertz) on cell 1, 15 kHz on cell 2, 60 kHz on cell 3, and 30 kHz on cell 4.

[0167] For the carrier configured with cell DTX, the network device can also use a specific format of multicast DCI 2-x (the DCI format can also be other formats) to activate or deactivate the cell DTX configuration of the carrier. For the CA scenario, the multicast DCI 2-x is only sent on one carrier, and multiple bits are carried in the DCI 2-x to indicate whether to activate or deactivate the carrier for multiple serving carriers configured with cell DTX configuration. After the terminal receives the DCI 2-x on one of its own serving carriers, it determines the time of activating / deactivating the cell DTX configuration on each serving carrier. The determination method is as follows:

[0168] The UE is expected to apply cell DTX or DRX activation / deactivation change at beginning of the slot X where the SCS of slot X is with respect to the active DL or UL BWP of the serving cell, respectively.

[0169] Slot X is the first slot whose beginning is no earlier than (i.e., the same as or after) the beginning of slot n+D, where D is the delay and n is the slot containing the PDCCH of DCI format 2_X based on SCS of PDCCH.

[0170] The values ​​of D are shown in Table 1:

[0171] Table 1

[0172] Step S2106: The first wake-up signal is used to instruct the terminal to wake up on one or more cells. The terminal is in a wake-up state in one or more cells for a first duration.

[0173] In this embodiment of the disclosure, when a terminal receives the first wake-up signal, the terminal is in a wake-up state within one or more cells for a first duration. Optionally, the first duration is configured by the network device or agreed upon by the communication protocol, and this embodiment of the disclosure does not limit it.

[0174] In some embodiments, the terminal receives a first wake-up signal, starts a first timer, and wakes up within a first duration of the first timer's validity. Alternatively, the first duration can be understood as being represented by the first timer's timing. In this embodiment, when the terminal receives the first wake-up signal, it starts the first timer. If the first timer expires, the terminal leaves the wake-up state, that is, the terminal enters a sleep state. If the terminal receives the first wake-up signal again, the first timer restarts. Alternatively, the terminal starts the first timer each time it receives a newly transmitted PDCCH. When the first timer expires and no next newly transmitted PDCCH has been received, the terminal enters a sleep state.

[0175] In some embodiments, the first timer corresponds to a cell, or it can be understood that the first timer is configured per cell. In some embodiments, the first timer corresponds to a terminal, or it can be understood that the first timer is configured per terminal.

[0176] In step S2107, the terminal receives / listens to the downlink signal or downlink channel of the second cell in the overlapping time period of the wake-up period of the second cell woken up by the first wake-up signal and the active time period of the cell DRX configuration of the second cell.

[0177] In the embodiments of the present disclosure, the wake-up period of the second cell woken up by the first wake-up signal is used to indicate that communication can be performed in the second cell, and the terminal can also perform communication in the active time period of the cell DRX configuration of the second cell, so the terminal can receive / listen to the downlink signal or downlink channel of the second cell in the overlapping time period of the wake-up period of the second cell woken up by the first wake-up signal and the active time period of the cell DRX configuration of the second cell.

[0178] It should be noted that the embodiments of the present disclosure are described by taking step S2107 as an example. In another embodiment, the terminal can also perform other operations.

[0179] In some embodiments, in the overlapping time period of the wake-up period of the second cell woken up by the first wake-up signal and the non-active time period of the cell DRX configuration of the second cell, the terminal receives / listens to other channels of the second cell except for the specific channel.

[0180] Optionally, the specific channel includes at least one of the following:

[0181] (1) SPS PDSCH.

[0182] (2) DCI format 2_0-DCI Format 2_5.

[0183] (3) Periodic / Semi-persistent CSI-RS configured in CSI report configuration in CSI-ReportConfig with reportQuantity including RI(for CSI reporting) (periodic / semi-persistent CSI-rs configured in CSI report configuration in CSI-ReportConfig with reportQuantity including RI(for CSI reporting)).

[0184] (4) Scheduling instruction for scheduling new data.

[0185] In some embodiments, the wake-up period of the second cell woken up by the first wake-up signal is ignored in an overlapping time period of the wake-up period and an inactive time period of the cell DRX configuration of the second cell. Alternatively, the above scheme can also be understood as the wake-up period being terminated in an overlapping time period of the wake-up period and an inactive time period of the cell DRX configuration of the second cell. In the embodiments of the present disclosure, the wake-up period of the second cell woken up by the first wake-up signal is used to indicate that communication can be performed in the second cell, but the terminal cannot perform communication in the inactive time period of the cell DRX configuration of the second cell, and therefore the terminal needs to ignore the wake-up state in the overlapping time period of the wake-up period of the second cell woken up by the first wake-up signal and the active time period of the cell DRX configuration of the second cell. Alternatively, it can also be understood that the terminal needs to terminate the wake-up period.

[0186] In some embodiments, the downlink channel or downlink signal of the second cell is received / listened to in the wake-up period of the second cell woken up by the first wake-up signal.

[0246] In some embodiments, the above method can include the method of the above-mentioned embodiments of the communication system side, the terminal side, the network device side, etc., which will not be repeated here.

[0247] FIG. 6 is a sixth flow diagram of a communication method of a wake-up signal according to an embodiment of the present disclosure. As shown in FIG. 6, the embodiments of the present disclosure relate to a communication method of a wake-up signal, and the above method includes:

[0248] Step S6101: The terminal receives an LP WUS on a cell A, and the cell DTX on the cell A is activated. In this case, the UE needs to consider the influence of the cell DTX on-off pattern (on-off configuration) on the cell A on the reception of the LP WUS.

[0249] 1. During the cell DTX active period (on period) of the cell A, the base station can normally send the LP WUS, and the UE can also normally listen to the LP WUS.

[0250] a) When UE monitors the LP WUS, UE wakes up. The UE's wake-up duration can be determined by a pre-configured timer. For example, a first timer is pre-configured, when UE wakes up, the first timer is started, when the timer expires, UE enters sleep state (i.e. end of PDCCH monitoring, or end of monitoring other downlink channels, etc.); Alternatively, a first timer is pre-configured, every time UE receives a PDCCH scheduling new transmission, the first timer is started, when the timer expires, if no next PDCCH scheduling new transmission is received, UE enters sleep state.

[0251] i. The first timer can be configured per cell or per UE.

[0252] b) Within the wake-up duration, UE's behavior can be as follows:

[0253] c) Mode 1: distinguish cell DTX active period and cell DTX non-active period

[0254] i. If the LP WUS indicates UE to wake up on cell B, the UE's wake-up period on cell B overlaps with the cell DTX active period on cell B, UE normally monitors all downlink channels / signals on cell B; (cell B can be the same as cell A or not)

[0255] ii. If the UE's wake-up period on cell B overlaps with the cell DTX non-active period on cell B, UE behavior can be:

[0256] 1. When entering the cell DTX non-active period, if the first timer is still running, then UE in the overlapping period, according to the agreement of cell DTX, does not monitor specific channels on cell B (i.e. the channels described in background 3), but still needs to monitor other downlink channels on cell B.

[0257] 2. Alternatively, when entering the cell DTX non-active period, the UE's wake-up period on cell B ends (i.e. the first timer ends).

[0258] d) Mode two: no differentiation between cell DTX active period and cell DTX non-active period

[0259] i. If the LP WUS indicates the UE to wake up on cell B, the UE monitors the downlink channels / signals on cell B normally during the wake-up period of the UE on cell B.

[0260] 2. Whether the base station can send LP WUS normally during the cell DTX non-active period (off period) of cell A. There are two modes:

[0261] a) Mode one: the base station can send LP WUS during the cell DTX non-active period of cell A, i.e. the UE still monitors the LP WUS during the cell DTX non-active period.

[0262] i. After the UE monitors the LP WUS, the UE will wake up, and the behavior of the UE after the wake-up is the same as 1-a), 1-b), 1-c), 1-d) above.

[0263] b) Mode two: the UE does not need to monitor the LP WUS during the cell DTX non-active period. At this time, the corresponding behavior of the base station is not to send the LP WUS.

[0264] Case 2: the UE receives the LP WUS on cell A, and cell DTX is not activated on cell A.

[0265] In this case, the reception of the LP WUS by the UE is not affected by the cell DTX on-off pattern. That is, the base station can always send the LP WUS, and the UE can always receive the LP WUS.

[0266] After the UE monitors the LP WUS, the UE will wake up, and the behavior of the UE after the wake-up is the same as 1-a), 1-b), 1-c), 1-d) above.

[0267] The non-activation of cell DTX on cell A includes the following three cases:

[0268] (1) cell DTX is not configured on cell A;

[0269] (2) cell DTX is configured on cell A, but cell DTX is not activated by DCI 2-9

[0270] (3) cell A is configured with cell DTX and cell DTX is activated using DCI 2-9, but the current time is still within the effective delay from the sending time of DCI 2-9 (not yet effective).

[0271] In some embodiments, Cell DTX / DRX can be configured separately for each carrier, and the SCS of the activated BWP on each carrier can be the same or different for the UE. For example, the UE has 4 serving carriers, cell 1 / 2 / 3 / 4. The SCS of the activated BWP on different carriers can be different, for example, SCS = 30 kHz on cell 1, cell 2 = 15 kHz, cell 3 = 60 kHz, and cell 4 = 30 kHz.

[0272] For the carrier configured with cell DTX / DRX, the base station can also use a specific format of multicast DCI 2-x (DCI format name has not been determined) to activate or deactivate the cell DTX / DRX configuration of the carrier. For the CA scenario, the multicast DCI is sent on one carrier, and the DCI carries multiple bits to indicate whether to activate or deactivate multiple serving carriers configured with cell DTX / DRX. After the UE receives the DCI on one of its own serving carriers, it determines the time of cell DTX / DRX activation / deactivation on each carrier. The determination method is as follows:

[0273] The UE is expected to apply cell DTX or DRX activation / deactivation change at the beginning of the slot X where the SCS of slot X is with respect to the active DL or UL BWP of the serving cell, respectively.

[0274] Slot X is the first slot whose beginning is no earlier than (i.e., same or after) beginning of slot n+D, where D is the delay and n is the slot containing the PDCCH of DCI format 2_X based on SCS of PDCCH.
