Furthermore, multiple systems may be combined (for example, a combination of LTE or LTE-A with 5G).

[0105] Network energy saving is a research direction that has attracted much attention.

[0106] In some embodiments, energy conservation of network devices can be achieved through cell DTX. For example, during the non-active period of cell DTX, the network device does not send some or all downlink channels or downlink signals on the cell. The state in which the network device normally sends downlink information can be recorded as DTX-On, indicating the DTX active period. The state in which the network device does not send some or all downlink channels or downlink signals is recorded as DTX-Off, indicating the DTX non-active period. In this disclosure, DTX-On, DTX active period, and DTX active period have the same meanings and can be used interchangeably. DTX-Off, DTX non-active period, and non-active period have the same meanings and can be used interchangeably.

[0107] In some embodiments, cell DTX and / or cell DRX can be configured separately for each carrier. For a terminal, the subcarrier spacing (SCS) of the activated bandwidth part (BWP) on each carrier may be the same or different. For example, a terminal has four serving carriers: cell1, cell2, cell3, and cell4. Assume that the SCS on cell1 is 30 kHz, the SCS on cell2 is 15 kHz, the SCS on cell3 is 60 kHz, and the SCS on cell4 is 30 kHz.

[0108] For carriers configured with cell DTX and / or cell DRX, the network device can send multicast downlink control information (DCI) in a specific format to the terminal. For example, it can be DCI2_X. The multicast DCI in a specific format is used to activate or deactivate the cell DTX and / or cell DRX configuration of the carrier. For carrier aggregation (CA) scenarios, the multicast DCI is sent on only one carrier. The DCI carries multiple bits to indicate whether to activate or deactivate cell DTX and / or cell DRX for multiple service carriers configured with cell DTX and / or cell DRX.

[0109] In some embodiments, after receiving DCI for activating or deactivating cell DTX and / or cell DRX configuration on a serving carrier, the terminal determines the activation and deactivation time of cell DTX and / or cell DRX on each carrier. For example, the determination may be made in the following manner:

[0110] 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.

[0111] 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.

[0112] The relationship between the SCS and the D value of the physical downlink control channel (PDCCH) can be referred to in the following Table 1:

[0113] Table 1

[0114] Due to the different SCSs on each carrier, it may happen that after the terminal receives the DCI for activating or deactivating the cell DTX and / or cell DRX configuration on a certain carrier, the effective time on different carriers is different. As shown in Figure 1b, assuming that the DCI is sent on slot 1 of cell 1, the SCS of cell 1 is 30 kHz, and referring to Table 1, it can be seen that the D value corresponding to cell 1 is 6. That is, on cell 1, the effective time of the DCI is slot (1+6), that is, the starting time of slot 7. The SCS of cell 2 is 15 kHz, and the D value corresponding to cell 2 is 3. On cell 2, the effective time of the DCI is the starting time of slot 4. This disclosure does not list cell 3 and cell 4 one by one, but it is obvious that the effective time on cell 2 is later than the effective time on other cells. That is, the time when cell DTX and / or cell DRX are activated or deactivated on cell 2 is later than that on other cells.

[0115] FIG2 is an interactive diagram of a communication method according to an embodiment of the present disclosure. As shown in FIG2 , the embodiment of the present disclosure relates to a communication method for use in a communication system 100, the method comprising:

[0116] Step S2101: Terminal 101 determines a first window.

[0117] In some embodiments, the first window is used to receive the first information. The terminal determines the first window and can receive the first information in the first window. The first window can be understood as a time window, a time point, or a time period.

[0118] In some embodiments, terms such as "moment", "time point", "time", and "time position" can be replaced with each other, and terms such as "duration", "period", "time window", "window", and "time" can be replaced with each other.

[0119] In some embodiments, the first information is used to activate or deactivate cell DTX and / or cell DRX for one or more carriers. It will be understood that cell DTX means that the network device discontinues sending downlink channels or downlink signals to the terminal. After the terminal activates cell DTX, the network device discontinues sending downlink channels or downlink signals to the terminal, and the terminal also discontinues receiving downlink channels or downlink signals sent by the network device. Cell DRX means that the network device discontinues receiving uplink channels or uplink signals sent by the terminal. After activating cell DRX, the terminal may discontinue sending uplink channels or uplink signals to the network device.

[0120] In some embodiments, the terms "component carrier (CC)", "cell", "frequency carrier", "carrier frequency" and the like can be used interchangeably.

[0121] In some embodiments, cell DTX is configured on the carrier used by the first information, and the first window can be determined in at least one of the following ways: determining the first window within a first time period window, the first time period window is located in the active time period of each cell DTX cycle in multiple cell DTX cycles, and the time interval between the end time of the first time period window and the start time of the next adjacent inactive time period is greater than or equal to a threshold; determining the first window within a second time period window, the second time period window is the active time period of a cell DTX cycle specified in every N cell DTX cycles, and the time interval between the end time of the second time period window and the start time of the next adjacent inactive time period is greater than or equal to the threshold; determining the first window within a third time period window, the third time period window is located in the inactive time period of each cell DTX cycle in multiple cell DTX cycles, and the time interval between the end time of the third time period window and the start time of the next adjacent active time period is greater than or equal to the threshold; determining the first window within a fourth time period window, the fourth time period window is the inactive time period of a cell DTX cycle specified in every N cell DTX cycles, and the time interval between the end time of the fourth time period window and the start time of the next adjacent active time period is greater than or equal to the threshold. It should be understood that the expression “the carrier used by the first information” may also mean the carrier of the first information, or the carrier that carries the first information, etc.

[0122] In some embodiments, if the carrier used by the network device to transmit the first information to the terminal is configured with cell DTX, a first time window may be determined within the active period of each cell DTX cycle within multiple cell DTX cycles of the carrier. The first time window represents a time window, time period, or time point. A cell DTX cycle includes an active period and an inactive period. During the active period, the network device may transmit downlink channels or downlink signals to the terminal. During the inactive period, the network device may not transmit downlink channels or downlink signals to the terminal. The first time window may be determined within the active period of each cell DTX cycle. The time interval between the end time of the first time window and the start time of the next inactive period is greater than or equal to a threshold. For example, assuming that the next cell DTX cycle after cell DTX cycle 1 is cell DTX cycle 2, the following items may be sequentially adjacent: active period 1 of cell DTX cycle 1, inactive period 1 of cell DTX cycle 1, active period 2 of cell DTX cycle 2, and inactive period 2 of cell DTX cycle 2. If the terminal determines the first time window during active period 1, the time interval between the end time of the first time window and the end time of inactive period 2 is greater than or equal to the threshold. The threshold value may be, for example, 3 milliseconds (ms). It is understood that 3 ms is merely an example, and the threshold value may be determined based on actual circumstances and is not limited in this disclosure. The start time of the first time window may be the start time of the activation period of the cell DTX cycle, or any time within the activation period of the cell DTX cycle, and may be earlier than or equal to the end time of the first time window. It is understood that if the start time of the first time window is earlier than the end time of the first time window, the first time window is a time period, and the first window may be determined within the first time window. For example, it may be any time period or any point in time within the first time window. If the start time of the first time window is equal to the end time of the first time window, the first time window is a point in time, and the first window may be determined within the first time window, and may be the same point in time as the first time window. If the first window is a time period, the terminal may receive the first information within the time period. If the first window is a point in time, the terminal may receive the first information at the point in time.

[0123] In some embodiments, if the carrier used by the network device to transmit the first information to the terminal is configured with cell DTX, a cell DTX cycle may be specified every N cell DTX cycles, and a second time window may be determined within the active period of the specified cell DTX cycle. The specified cell DTX cycle may, for example, be the Mth cell DTX cycle among the N cell DTX cycles. Alternatively, the second time window may be determined within the active period of the next cell DTX cycle every P cycles starting from the current cell DTX cycle. For example, the second time window may be determined within the active period of the first cell DTX cycle, within the active period of the 1+Pth cell DTX cycles, within the active period of the 1+2*Pth cell DTX cycles, and so on. N, M, P, and Q are all positive integers. The specific values ​​may be determined based on actual circumstances and are not limited in this disclosure. The time interval between the end time of the second time window and the start time of the next adjacent inactive period is greater than or equal to a threshold. The threshold may be, for example, 3 ms, but is not limited in this disclosure. The start time of the second time window can be the start time of the activation period of the specified cell DTX cycle, or any time within the specified cell DTX activation period, and can be earlier than or equal to the end time of the second time window. The second time window can be a time period or a time point. If the second time window is a time period, the first window can be any time period or any time point within the second time window. If the second time window is a time point, the first window can be the same time point as the second time window. The terminal can receive the first information in the first window.

[0124] In some embodiments, if the carrier used by the network device to transmit the first information to the terminal is configured with cell DTX, a third time window may be determined within the inactive period of each of the carrier's multiple cell DTX cycles. The third time window represents a time window, time period, or time point. The time interval between the end of the third time window and the start of the next active time period is greater than or equal to a threshold. For example, assuming the next cell DTX cycle after cell DTX cycle 1 is cell DTX cycle 2, the following items may be sequentially adjacent: active time period 1 of cell DTX cycle 1, inactive time period 1 of cell DTX cycle 1, active time period 2 of cell DTX cycle 2, and inactive time period 2 of cell DTX cycle 2. If the terminal determines the third time window within inactive time period 1, the time interval between the end of the first time window and the start of active time period 2 is greater than or equal to a threshold. The threshold may be, for example, 3 ms, but is not limited thereto. The start time of the third time window may be the start time of the inactive time period, or any time within the inactive time period, but not earlier than the end time of the third time window. The third time window may be a time period or a time point. If the third time period window is a time period, the first window may be any time period or any time point within the third time period window. If the third time period window is a time point, the first window may be the same time point as the third time period window. The terminal may receive the first information in the first window.

[0125] In some embodiments, if the carrier used by the network device to transmit the first information to the terminal is configured with cell DTX, a cell DTX cycle may be specified within every N cell DTX cycles, and a fourth time window may be determined within the inactive period of the specified cell DTX cycle. The specified cell DTX cycle may be, for example, the Mth cell DTX cycle among the N cell DTX cycles. Alternatively, the fourth time window may be determined within the active period of the next cell DTX cycle after every P cycles, starting from the current cell DTX cycle. The time interval between the end time of the fourth time window and the start time of the next adjacent inactive period is greater than or equal to a threshold. For example, assume that the specified cell DTX cycle is the Mth cell DTX cycle among the N cell DTX cycles. The following items may be sequentially adjacent: active period 3 of the Mth cell DTX cycle, inactive period 3 of the Mth cell DTX cycle, active period 4 of the M+1th cell DTX cycle, and inactive period 4 of the M+1th cell DTX cycle. If the terminal determines the fourth time window during inactive period 3, the time interval between the end time of the fourth time window and the start time of active period 4 is greater than or equal to the threshold. The threshold may be, for example, 3 ms, but this disclosure does not limit this.

[0126] In some embodiments, the network device may configure N for the terminal.

[0127] In some embodiments, the terminal may determine N based on L cell DTX cycle durations. The L cell DTX cycles are the cell DTX cycles of the L carriers configured with cell DTX. The total duration of the N cell DTX cycles is the least common multiple of the L cell DTX cycle durations. Assuming that the cell DTX cycles of the L carriers correspond to durations 1, 2, and 3, respectively, the total duration of the N cell DTX cycles is the least common multiple of duration 1, duration 2, and duration 3. For example, the least common multiple is X times duration 1, Y times duration 2, and Z times duration 3. N can be determined based on these multiples. That is, for a carrier whose cell DTX cycle duration is duration 1, a second time period window or a fourth time period window can be determined for every X cell DTX cycles. For a carrier whose cell DTX cycle duration is duration 2, a second time period window or a fourth time period window can be determined for every Y cell DTX cycles. For a carrier whose cell DTX cycle duration is 3, a second time period window or a fourth time period window may be determined every Z cell DTX cycles.

[0128] In some embodiments, if the carrier used by the network device to transmit the first information to the terminal is not configured with cell DTX but is configured with cell DRX, the first window may be determined based on the cell DRX cycle. The end time of the first window may be before the start time of the cell DRX cycle. For example, a time offset may be set, and the end time of the first window may be calculated by adding the time offset before the start time of the cell DRX cycle. The start time of the first window may be earlier than or equal to the end time of the first window.

[0129] In some embodiments, if the carrier used by the network device to transmit the first information to the terminal is not configured with cell DTX or cell DRX, the network device may configure a period for the terminal to determine the first window, and the terminal may determine the first window within the configured period. For example, if the network device configures a period of Tms, the terminal may determine a first window every Tms, starting from the current moment. The time interval between the end time of the first window and the start time of the next period is greater than or equal to a threshold. The threshold may be, for example, 3ms, but this disclosure is not limited thereto.

[0130] Step S2102: The terminal 101 determines whether the first information sent by the network device 102 is received in the first window.

[0131] In some embodiments, the network device 102 sends first information to the terminal 101 on a first window.

[0132] In some embodiments, the terminal expects to receive the first information on the first window.

[0133] In some embodiments, the network device 102 may fail to send the first information, the first information may be lost during transmission, or the terminal 102 may fail to receive the first information. If the above examples occur, the terminal does not receive the first information sent by the network device in the first window.

[0134] In some embodiments, the first information is used to activate or deactivate cell DTX and / or cell DRX of one or more carriers. For example, the first information can be used to activate cell DTX of a certain carrier. For another example, the first information can be used to deactivate cell DTX of a certain carrier. For another example, the first information can be used to simultaneously activate cell DTX and cell DRX of a certain carrier. For another example, the first information can be used to simultaneously deactivate cell DTX and cell DRX of a certain carrier. The first information can be used to activate cell DTX of multiple carriers. For another example, the first information can be used to activate cell DTX of a certain carrier A and deactivate cell DRX of a certain carrier B. This disclosure does not exhaustively enumerate all possible scenarios, but it will be understood that it is not limited to the aforementioned examples.

[0135] In some embodiments, if a terminal determines that it has received first information sent by a network device during a first window, it may activate or deactivate cell DTX and / or cell DRX for one or more carriers based on the first information. For example, the first information may be used to activate cell DTX for a particular carrier, and cell DTX for that carrier may be activated based on the first information. In another example, the first information may be used to deactivate cell DTX for a particular carrier, and cell DTX for that carrier may be deactivated based on the first information. In another example, the first information may be used to simultaneously activate cell DTX and cell DRX for a particular carrier, and cell DTX and cell DRX for that carrier may be activated based on the first information. In another example, the first information may be used to activate cell DTX for multiple carriers, and the terminal may simultaneously activate cell DTX for multiple carriers based on the first information. In another example, the first information may be used to activate cell DTX for carrier A and deactivate cell DRX for carrier B. The terminal may activate cell DTX for carrier A and deactivate cell DRX for carrier B based on the first information. This disclosure does not exhaustively enumerate all possible scenarios, but it should be understood that the disclosure is not limited to the aforementioned examples.

[0136] In some embodiments, if the terminal determines that the first information sent by the network device is received in the first window, the cell DTX and / or cell DRX of one or more carriers may be activated or deactivated based on a default rule.

[0137] Step S2103 , the network device 102 sends second information to the terminal 101 .

[0138] In some embodiments, the terminal 101 receives second information sent by the network device.

[0139] It should be understood that the second information can be sent simultaneously with the first information or after the first information. The second information can be sent with the first information via the same signaling or via different signaling.

[0140] In some embodiments, the second information is used to configure a default rule. The default rule indicates whether to activate or deactivate cell DTX and / or cell DRX, whether to receive a target channel during a cell DTX inactive period, and whether to transmit a target channel during a cell DRX inactive period. The terminal determines the default rule based on the second information from the network device, so that when the first information is not received in the first window, the terminal can proceed according to the pre-configured default rule.

[0141] In some embodiments, the terminal may receive the second information and, in some circumstances, such as failure to receive the first information sent by the network device within a specific time window, perform at least one of the following based on default rules: activate or deactivate at least one of the following: cell DTX and cell DRX; determine whether to receive or not receive a target channel during a cell DTX inactive period; or determine whether to transmit or not transmit a target channel during a cell DRX inactive period. The target channel may represent one or more channels on one or more carriers configured with cell DTX and / or cell DRX.

[0142] In some embodiments, the default rule includes at least one of the following: for one or more carriers configured with cell DTX, activating or deactivating cell DTX for all carriers. For one or more carriers configured with cell DRX, activating or deactivating cell DRX. For one or more carriers configured with cell DTX, maintaining the current activation or deactivation state of DTX. For one or more carriers configured with cell DRX, maintaining the current activation or deactivation state of DRX. For each of the one or more carriers configured with cell DTX, activating or deactivating DTX separately. For each of the one or more carriers configured with cell DRX, activating or deactivating DRX separately. For a target channel on the one or more carriers configured with cell DTX, determining whether the target channel is received or not received during a cell DTX inactive period. For a target channel on the one or more carriers configured with cell DTX, determining whether the target channel is transmitted or not transmitted during a cell DRX inactive period. For a target channel on each of the one or more carriers configured with cell DTX, determining whether the target channel is received or not received during a cell DTX inactive period. For a target channel on each of one or more carriers configured with cell DRX, it is determined whether to send the target channel during a cell DRX inactive period.

[0143] In some embodiments, for one or more carriers configured with cell DTX, the default rule may include activating or deactivating cell DTX for all carriers, or maintaining the current activation or deactivation state of cell DTX. It will be appreciated that if the default rule includes activating cell DTX, then for carriers with deactivated cell DTX, cell DTX may be activated. For carriers with activated cell DTX, the cell DTX state may continue to be maintained. If the default rule includes maintaining the current activation or deactivation state, then for carriers with deactivated cell DTX, the cell DTX deactivated state may continue to be maintained. For carriers with activated cell DTX, the cell DTX state may continue to be maintained.

[0144] In some embodiments, for one or more carriers configured with cell DRX, the default rule may include activating or deactivating cell DRX, or maintaining the current activation or deactivation state of cell DRX. It will be appreciated that if the default rule includes activating cell DRX, then for a carrier with deactivated cell DRX, cell DRX may be activated. For a carrier with activated cell DRX, the cell DRX state may continue to be maintained. If the default rule includes maintaining the current activation or deactivation state, then for a carrier with deactivated cell DRX, the cell DRX state may continue to be maintained. For a carrier with activated cell DRX, the cell DRX state may continue to be maintained.

[0145] In some embodiments, for one or more carriers configured with cell DTX, the default rule may include activating or deactivating cell DTX for each carrier separately. For example, assuming the multiple carriers include carrier A and carrier B, the default rule may include activating or deactivating cell DTX for carrier A and activating or deactivating cell DTX for carrier B. The activation or deactivation rules for carrier A and carrier B may be the same or different. For example, the default rule may be activating cell DTX for carrier A and deactivating cell DTX for carrier B.

[0146] In some embodiments, for one or more carriers configured with cell DRX, a default rule may include activating or deactivating the cell DRX for each carrier separately. For example, assuming the multiple carriers include carrier A and carrier B, the default rule may include activating or deactivating the cell DRX for carrier A and activating or deactivating the cell DRX for carrier B. The activation or deactivation rules for carrier A and carrier B may be the same or different. For example, the default rule may be activating the cell DRX for carrier A and deactivating the cell DRX for carrier B.

[0147] In some embodiments, for a target channel on a carrier configured with cell DTX and / or cell DRX, if the target channel has a single channel, channel 1 is assumed. Default rules may include: whether to receive channel 1 during periods of cell DTX inactivity, and whether to transmit channel 1 during periods of cell DRX inactivity. If the target channel has multiple channels, channels 1 and 2 are assumed to be included. The default rules uniformly specify: whether to receive channels 1 and 2 during periods of cell DTX inactivity, and whether to transmit channels 1 and 2 during periods of cell DRX inactivity. Alternatively, the default rules may be specified separately for channels 1 and 2, including: whether to receive channel 1 during periods of cell DTX inactivity, whether to receive channel 2 during periods of cell DTX inactivity, whether to transmit channel 1 during periods of cell DRX inactivity, and whether to transmit channel 2 during periods of cell DRX inactivity. It will be appreciated that if separate rules are specified for channels 1 and 2, the rules for transmitting or receiving channels 1 and 2 may be the same or different.

[0148] In some embodiments, if there is only one target channel on multiple carriers configured with cell DTX and / or cell DRX, channel 3 is assumed. That is, all of the multiple carriers configured with cell DTX and / or cell DRX include channel 3. A default rule may specify channel 3 on the multiple carriers, including whether to receive channel 3 during a cell DTX inactive period and whether to transmit channel 3 during a cell DRX inactive period. That is, if the default rule specifies receiving channel 3 during a cell DTX inactive period, each of the multiple carriers receives channel 3. If the default rule specifies not receiving channel 3 during a cell DTX inactive period, each of the multiple carriers does not receive channel 3. If the default rule specifies transmitting channel 3 during a cell DRX inactive period, each of the multiple carriers transmits channel 3. If the default rule specifies not transmitting channel 3 during a cell DRX inactive period, each of the multiple carriers does not transmit channel 3. If there are multiple target channels, channels 1 and 2 on carrier A and channels 3 and 4 on carrier B are assumed. Default rules can be uniformly defined for multiple channels on multiple carriers, including: whether to receive channels 1, 2, 3, and 4 during periods of cell DTX inactivity; and whether to transmit channels 1, 2, 3, and 4 during periods of cell DRX inactivity. Default rules can also be defined separately for channels 1, 2, 3, and 4. While examples are not provided in this disclosure, it is understood that if separate rules are defined for channels 1, 2, 3, and 4, the rules governing whether to transmit or receive on each channel can be the same or different.

[0149] In some embodiments, for a target channel on each of multiple carriers configured with cell DTX and / or cell DRX, a default rule may separately specify whether the target channel on each carrier is to be transmitted or received. Assuming that the multiple carriers include carrier C and carrier D, the target channels may include target channel C on carrier C and target channel D on carrier D. Target channel C and target channel D may each be one or more channels. Assuming that target channel C includes channel 5 and target channel D includes channel 6 and channel 7, the default rules may include: whether channel 5 is to be received during the cell DTX inactive period of carrier C; whether channels 6 and channel 7 are to be received during the cell DTX inactive period of carrier D; whether channel 5 is to be transmitted during the cell DRX inactive period of carrier C; and whether channels 6 and channel 7 are to be transmitted during the cell DRX inactive period of carrier D.

[0150] The carriers in this disclosure refer to one or more serving carriers. The carrier used to send the first information in this disclosure may be any of the one or more serving carriers. For example, the carrier used to send the first information may be any of the serving carriers, and may be used to activate or deactivate cell DTX and / or cell DRX for multiple serving carriers. The carriers used to send the first information may also be multiple serving carriers.

[0151] In some embodiments, default rules may be defined in the protocol.

[0152] In some embodiments, the default rule may include deactivating cell DTX and activating cell DRX. This can avoid the situation where a transmitting end sends information but a receiving end fails to receive the information.

[0153] In step S2104, the terminal 101 determines that the first information is not received in the first window, and performs at least one of the following based on the default rules: activating and deactivating the cell DTX and / or cell DRX of one or more carriers; determining whether to receive the target channel or not during the cell DTX inactive period; determining whether to send the target channel or not during the cell DRX inactive period.

[0154] In some embodiments, the default rule may be configured by the network device or defined by the protocol. For example, if the network device is not configured with a default rule, and a default rule is defined in the protocol, the terminal may perform at least one of the following according to the default rule in the protocol: activating and deactivating the cell DTX and / or cell DRX of one or more carriers; determining whether to receive the target channel or not to receive the target channel during the cell DTX non-activation period; determining whether to send the target channel or not to send the target channel during the cell DRX non-activation period. If the protocol does not define a default rule, and the network device configures a default rule for the terminal, the terminal may perform at least one of the examples given in this embodiment according to the default rule configured by the network device. If the protocol defines a default rule, and the network device configures a default rule for the terminal, the terminal may determine the default rule to be used from the default rule defined by the protocol and the default rule configured by the network device, and perform at least one of the examples given in this embodiment based on the determined default rule. The manner in which the terminal performs at least one of the examples given in this embodiment based on the default rule can refer to the above embodiment, and the present disclosure will not be repeated here.

[0155] In some embodiments, the network device may monitor the conditions of the terminal's receiving or transmitting channels. If the conditions of the terminal's receiving or transmitting channels are abnormal, the network device may resend the first information. For example, the network device may send first information to the terminal to instruct the terminal to deactivate cell DTX. That is, the network device expects to subsequently transmit downlink channels or downlink signals during all time periods, rather than only during the cell DTX activation period. However, due to factors such as loss of the first information during transmission or reception failure, the terminal determines that it has not received the first information and does not deactivate cell DTX, or activates cell DTX for the carrier based on default rules, or maintains the activation state of the carrier based on default rules. This may result in the network device sending a downlink channel to the terminal, but the terminal not receiving it. The network device may monitor the terminal's feedback regarding the downlink channel or downlink signal sent by the network device. If the network device does not receive feedback from the terminal, it may determine that the terminal's receiving channel is abnormal and resend the first information.

[0156] In some embodiments, the effective time of the default rule can be determined based on the end time of the first window. The effective time of the default rule can be understood as the moment when the terminal performs a certain operation based on the default rule. Or, it can be understood as the moment when the terminal performs a certain operation based on the default rule and the operation is successful. For example, the default rule is to activate the cell DTX of a certain carrier. Then the effective time of the default rule is the moment when the terminal activates the cell DTX of a certain carrier, or the moment when the cell DTX of a certain carrier is successfully activated. The effective time of the default rule can be determined based on the end time of the first window. For example, the effective time of the default rule can be the end time of the first window. For another example, the effective time of the default rule can be the moment after the end time of the first window passes through a preset time period.

[0157] In some embodiments, the effective time of the default rule is the starting time of the first time unit or the starting time of the first time unit after the first time unit; the first time unit is the time unit corresponding to the sum of the end time of the first window and the offset; the offset corresponds to the subcarrier spacing of the cell.

[0158] In some embodiments, the offset can be determined based on the subcarrier spacing of the carrier. For example, reference can be made to Table 1. The time unit corresponding to the offset from the end moment of the first window is the first time unit. If the moment after the offset from the end moment of the first window is the start moment of the first time unit, the effective time of the default rule is the start moment of the first time unit. If the moment after the offset from the end moment of the first window is any moment within the first time unit, the effective time of the default rule is the start moment of the first time unit after the first time unit. Among them, the start moment of the first time unit after the first time unit can also be understood as the end moment of the first time unit.

[0210] In some embodiments, the above method may include the method of the above embodiments related to the communication system 100, the terminal 101, the network device 102, etc., which will not be repeated here.

[0211] The present disclosure also provides a communication method as follows:

[0212] In some embodiments, the base station sends DCI 2-X within a specified period, where DCI 2-X is used to activate / deactivate cell DTX / DRX of one or more carriers. The specified period occurs periodically.

[0213] In some embodiments, DCI 2-X may be the first information.

[0214] In some embodiments, a user equipment (UE) needs to monitor DCI 2-X every time in the prescribed period, and the UE expects to detect DCI 2-X every time in the prescribed period.

[0215] In some embodiments, the UE may also be the terminal 101 .

[0216] In some embodiments, possible definitions of "prescribed period" include:

[0217] In some embodiments, if cell DTX is configured on the carrier where DCI 2-X is located (cell DRX may or may not be configured)

[0218] (1) Within the active period window of each cell DTX cycle on the carrier where DCI 2-X is located, the time interval between the end time of the window and the start time of the next inactive period is set to be greater than or equal to a threshold value, such as 3ms.

[0219] In some embodiments, the threshold value may be a threshold value. The set time period window may be, for example, a first time period window.

[0220] (2) In every N cell DTX cycles on the carrier where DCI 2-X is located, set a time window in the active period of a cell DTX cycle. Furthermore, set the time interval between the end time of the window and the start time of the next non-active period to be greater than or equal to a threshold value (for example, 3ms).

[0221] In some embodiments, the set period window may be, for example, a second time period window.

[0222] (3) Set a time window in the non-active period of each cell DTX cycle on the carrier where DCI 2-X is located. Furthermore, set the time interval between the end time of the window and the start time of the next active period to be greater than or equal to the threshold value (for example, 3ms).

[0223] In some embodiments, the set period window may be, for example, a third time period window.

[0224] (4) In each of the N cell DTX cycles on the carrier where DCI 2-X is located, a time window is set in the non-active period of a cell DTX cycle. Furthermore, the time interval between the end time of the window and the start time of the next active period is set to be greater than or equal to a threshold value (e.g., 3ms).

[0225] In some embodiments, the set period window may be, for example, a fourth time period window.

[0226] In some embodiments, in the above N periods, N can be directly configured by the base station through high-layer signaling, or calculated in some way. For example, the duration of the N periods is the least common multiple of the cell DTX period values ​​of multiple carriers configured with cell DTX.

[0227] In some embodiments, if cell DTX is not configured on the carrier where DCI 2-X is located.

[0228] In some embodiments, regardless of whether cell DTX is configured or not, the "prescribed period" is determined such that, as long as the prescribed period occurs with a period T, the UE only needs to monitor DCI 2-X during the prescribed period. T can be configured by the base station or determined according to protocol definitions. For example, if cell DTX is not configured on the carrier containing DCI 2-X, but cell DRX is configured, the period can be determined based on the cell DRX period. For example, the "prescribed period" is a set window of time before the start time of each cell DRX cycle on the carrier containing DCI 2-X.

[0229] If the UE does not detect DCI 2-X within a specified period, how should the UE determine whether to activate or deactivate cell DTX / DRX on each carrier configured with cell DTX / DRX? The following "default behavior" is the UE's unilateral assumption of the gNB behavior and the UE's own behavior. In practice, the gNB's behavior may be inconsistent with the UE's assumption of the default behavior.

[0230] In some embodiments, not detecting DCI 2-X may be determining that the first information is not received.

[0231] (1) Configuration by the base station: The base station can configure the default behavior for each carrier configured with cell DTX / DRX when no DCI2-X is received during a specified period.

[0232] In some embodiments, the base station configures a default behavior for cell DTX and DRX on all cells. The default behavior can be to activate all cell DTX and cell DRX on all cells, or to deactivate all cell DTX and cell DRX on all cells, or to maintain the current activation / deactivation state. That is, if the cell DTX is currently in the deactivated state, the deactivated state is maintained; if the cell DTX is currently in the activated state, the activated state is maintained. This configuration is the same for cell DTX and DRX of all cells.

[0233] In some embodiments, the base station configures each cell separately. For cell 1, the base station configures the default behavior of cell 1 to deactivate cell DTX and / or cell DRX. That is, if cell DTX and cell DRX are configured on cell 1, both are deactivated. If only cell DTX or cell DRX is configured, cell DTX or cell DRX is deactivated. For cell 2, the base station configures the default behavior of cell 2 to activate cell DTX and / or cell DRX.

[0234] In some embodiments, the base station separately configures default behaviors for cell DTX, such as cell DTX activation and deactivation, and default behaviors for cell DRX, such as cell DRX activation and deactivation. This configuration is the same for all cells.

[0235] In some embodiments, cell DTX / DRX is configured separately for each cell. If cell DTX and cell DRX are configured for cell 1, the base station can separately configure the default behavior for DTX and the default behavior for DRX for that cell. For example, the base station can configure the default behavior for DTX on cell 1 to be deactivated, and the default behavior for cell DRX to be activated.

[0236] In some embodiments, the default behavior can also be configured for each channel separately.

[0237] For example, for channels such as reference signals and SPS PDSCH that are affected by cell DTX and not sent during the cell DTX non-active period, default behaviors are configured separately (that is, when DCI 2-X is not received, for a certain channel, whether to adopt the behavior when cell DTX is not activated, the behavior when cell DTX is activated, or to continue to adopt the current activation / deactivation of cell DTX); for channels such as SR / SRS / CG-PUSCH that are affected by cell DRX and not sent during the cell DRX non-active period, default behaviors are configured separately.

[0238] (2) Defined by protocol

[0239] The protocol definition method can refer to the above embodiment. It is only necessary to change the base station configuration to the protocol definition.

[0240] In some embodiments, the default behavior can also be defined for each channel separately.

[0241] In some embodiments, regarding the default behavior: for cell DTX, the default behavior may be deactivation; for cell DRX, the default behavior may be activation. This can avoid the situation where the transmitter sends information but the receiver does not receive it.

[0242] In some embodiments, if DCI 2-x is not received within a specified period, the default behavior described above may take effect after a period T1 after the end of the specified period. For more detail, refer to the above-described embodiments for the effective time of DCI 2-x on each carrier: assuming that the end of the "prescribed period" is at the end of slot n, then on each carrier, the default behavior takes effect starting from the start time of slot X on each carrier, where the start time of slot X is no earlier than the start time of slot n+D on the carrier transmitting DCI 2-X. D has different values ​​for different subcarriers; see Table 1 for specific values.

[0243] In some embodiments, D may be an offset, slot n+D may be a first time unit, and slot n may be a first time window.
