[0199] Mode 6: For a UE, the PCell is configured to wake up each cell A. Cell A can be a candidate SCell, which can be one or more. Specifically, an RRC message or system information carries the configuration for waking up each cell. If the UE wants to wake up a cell or request the PCell to add / activate an SCell for it, the UE sends a wake-up message or signal based on the configuration. The wake-up configuration includes at least one of the following:

[0200] The identification and index of the cell;

[0210] The time-frequency position of sending PUCCH, SR, SRS or PRACH can be associated with the purpose of waking up the cell. For example, PUCCH, SR, SRS or PRACH at a certain time-frequency is used to wake up the cell.

[0211] The time-frequency position of sending PUCCH, SR, SRS or PRACH can be associated with the index of waking up a certain cell. For example, PUCCH, SR or PRACH of a certain time-frequency is used to wake up a certain cell.

[0212] The time-frequency location of sending PUCCH, SR, SRS or PRACH can be associated with the purpose of the wake-up frequency. For example, the PUCCH, SR, SRS or PRACH of a certain time-frequency is used for the wake-up frequency.

[0213] The time-frequency position of sending PUCCH, SR, SRS or PRACH can be associated with the index of waking up a certain frequency point. For example, PUCCH, SR or PRACH of a certain time-frequency is used to wake up a certain frequency point.

[0215] Example 3 (activation / deactivation)

[0216] When an SCell is activated, the cell can indicate whether the SCell should send a reference signal or sleep. Possible methods are as follows:

[0217] Method 1: In the SCell activation / deactivation MAC CE command, for each activated SCell, the MAC CE indicates whether reference signals are transmitted. Specifically, in the SCell activation / deactivation MAC CE command, the Ci field indicates whether the SCell with SCell index i is activated. The Reference Signal i field indicates whether the SCell with SCell index i transmits reference signals or wakes up if it is activated. For example, if the Ci field is 1, indicating that the SCell with SCell index i is activated, and the corresponding Reference Signal i field is 1, the SCell with SCell index i transmits reference signals or wakes up; otherwise, it does not transmit reference signals or goes into sleep mode.

[0218] A new LCID or eLCID is introduced to indicate whether the SCell activation / deactivation MAC CE command carrying the reference signal is sent.

[0219] After receiving the MAC CE, if a SCell indicates not to send reference signals or is in sleep mode, the UE considers the SCell to have stopped sending reference signals after the MAC CE takes effect. If a SCell indicates to send reference signals or wakes up, the UE considers the SCell to have started sending reference signals after the MAC CE takes effect.

[0220] Method 2: In the SCell activation / deactivation MAC CE command, for each deactivated SCell, the MAC CE indicates whether a reference signal is transmitted. Specifically, in the SCell activation / deactivation MAC CE command, the Ci field indicates whether the SCell with SCell index i is activated. The Reference Signal i field indicates whether the SCell with SCell index i is deactivated and whether it transmits a reference signal or goes into sleep mode. For example, if the Ci field is 0, indicating that the SCell with SCell index i is deactivated, and the corresponding Reference Signal i field is 1, the SCell with SCell index i transmits a reference signal or wakes up; otherwise, it does not transmit a reference signal or goes into sleep mode.

[0221] A new LCID or eLCID is introduced to indicate whether the SCell activation / deactivation MAC CE command carrying the reference signal is sent.

[0222] After receiving the MAC CE, if a SCell indicates not to send reference signals or is in sleep mode, the UE considers the SCell to have stopped sending reference signals after the MAC CE takes effect. If a SCell indicates to send reference signals or wakes up, the UE considers the SCell to have started sending reference signals after the MAC CE takes effect.

[0223] Mode 3: In the reference signal transmission activation / deactivation MAC CE command, for each SCell, the MAC CE indicates whether the reference signal is transmitted or in sleep mode. Specifically, the Reference Signal i field in the reference signal transmission MAC CE command indicates whether the SCell with SCell index i transmits reference signals or is in sleep mode. For example, if the Reference Signal i field is 1, the SCell with SCell index i transmits reference signals or wakes up; otherwise, it does not transmit reference signals or is in sleep mode.

[0224] A new LCID or eLCID is introduced to indicate the reference signal to send activation / deactivation MAC CE commands.

[0225] After receiving the MAC CE, if a SCell indicates not to send reference signals or is in sleep mode, the UE considers the SCell to have stopped sending reference signals after the MAC CE takes effect. If a SCell indicates to send reference signals or wakes up, the UE considers the SCell to have started sending reference signals after the MAC CE takes effect.

[0226] Method 4: DCI indicates whether the reference signal is transmitted. For each SCell, the DCI indicates whether the reference signal is transmitted or in sleep mode. Specifically, in the DCI, the i-th bit in the bitmap corresponds to the SCell with SCell index i. If this bit is 1, the SCell with SCell index i transmits the reference signal or wakes up. Otherwise, the reference signal is not transmitted or the SCell is in sleep mode.

[0227] Method 5: DCI indicates whether reference signals are being transmitted. For each SCell, the DCI indicates whether reference signals are being transmitted or in sleep mode. Specifically, in the DCI, the i-th bit in the bitmap corresponds to the SCell with SCell index i. If this bit is 1, the SCell with SCell index i starts transmitting reference signals or wakes up; otherwise, it stops transmitting reference signals or goes into sleep mode.

[0228] If a SCell is activated / deactivated, the DCI indicates whether the reference signal of the SCell is sent.

[0229] Method 6: SCell dormancy DCI indicates whether reference signals are transmitted. For each SCell or SCell group transferred to the dormant BWP, the DCI indicates whether reference signals are transmitted or dormant. Specifically, in the DCI, the i-th bit in the bitmap corresponds to the SCell or SCell group with SCell index i. If this bit is 1, the SCell or SCell group with SCell index i starts transmitting reference signals or wakes up; otherwise, it stops transmitting reference signals or goes into dormancy.

[0230] Example 4 (UE requests to report RRC message)

[0231] The PCell configures multiple cells (including SCells and candidate SCells) or frequency points for the UE, for example, through RRC messages such as RRC reconfiguration and UEInformationRequest. The RRC message includes at least one of the following:

[0232] frequency;

[0233] Cell resource configuration, such as cell identification, cell index, and radio resource configuration;

[0234] Indication of cell status, for example, an RRC message carries an indication that the cell is a candidate cell for an SCell, the cell is a deactivated SCell, the cell is sleeping or not sending reference signals, the cell can be woken up, etc.;

[0235] Frequency status indication, for example, the RRC message carries an indication that the cell on the frequency is a candidate cell for the SCell, that the cell on the frequency is in sleep mode or not sending a reference signal, that the cell on the frequency can be awakened, etc.

[0236] The services that the cell may provide. For example, for a cell, the RRC message carries an indication of the amount of data, data rate, etc. that the cell may or is expected to provide to the UE;

[0237] The services that one or more cells on a frequency may provide. For example, for a frequency, the RRC message carries an indication of the amount of data that one or more cells on the frequency may or are expected to provide to the UE, the data rate, etc.

[0238] The priority of the cell: if the priority of the cell is high, the PCell will preferentially select the cell to be configured as the SCell of the UE, or the cell can be woken up preferentially. Conversely, if the priority of the cell is low, the PCell will laggingly select the cell as the SCell of the UE, or the cell can be woken up laggingly. For a cell, the RRC message carries a priority.

[0239] Frequency priority: If the frequency priority is high, the PCell will preferentially select the cell on this frequency as the SCell of the UE, or the cell on this frequency can be woken up preferentially. Conversely, if the frequency priority is low, the PCell will laggingly select the cell on this frequency as the SCell of the UE, or the cell on this frequency can be woken up later. For a frequency, the RRC message carries a priority.

[0240] The association between the wake-up signal and the cell. The time-frequency resources used to send the wake-up signal are associated with the cell. For example, the PUCCH, SR, SRS, or PRACH at a certain time or frequency domain is associated with a certain cell. The SR / PUCCH sent at a certain time or frequency domain is used to wake up a certain cell. The RRC message configures the PUCCH, SR, SRS, or PRACH resources used to wake up the cell and indicates that these resources are used to wake up the cell. For a cell, the RRC message configures the PUCCH, SR, SRS, or PRACH resources used to wake up the cell and indicates that these resources are used to wake up the cell.

[0241] The UE is requested to wake up the cell. For example, when certain conditions are met, the UE may send a signal or message or MAC CE to the PCell, SCell or candidate SCell to wake up the cell.

[0242] In addition, the UE sends an RRC message to wake up the cell to the PCell, for example, through RRC messages such as UEInformationResponse and UEAssistanceInformation.

[0243] Indication that the UE requests to wake up the cell, for example, the UE expects to wake up the SCell or candidate cell; the UE expects the cell to provide service to it;

[0244] The UE requests to wake up a cell and indicates the cell index. If the UE expects to wake up a certain SCell or a configured candidate cell, or the UE expects a certain cell to provide service, the UE may report the cell index.

[0245] The number of cells that the UE requests to wake up. If the UE expects to wake up one or more SCells or configured candidate cells, or the UE expects one or more cells to provide services for it, the UE can report the number of cells;

[0246] The UE's expected data volume or data rate: The UE can predict the traffic volume of incoming data, calculate the data volume or data rate that needs to be transmitted, and report it.

[0247] Example 5 (UE requests to report MAC CE)

[0248] The PCell enables the UE to wake up the cell through a MAC CE. The MAC CE includes at least one of the following:

[0249] Enable UE wake-up. For example, the MAC CE carries one bit. If it is 1, the UE wakes up the cell or frequency. Otherwise, the UE cannot wake up the cell or frequency.

[0250] Enable UE reporting. For example, the MAC CE carries one bit. If it is 1, the UE reports the cell or frequency that it expects to wake up. Otherwise, the UE cannot report.

[0251] In addition, the UE wakes up the cell through a MAC CE, which includes at least one of the following:

[0253] Indication of the frequency that the UE requests to wake up. For example, the MAC CE carries one bit. If the bit is 1, the UE expects to wake up the cell on the frequency, or the UE expects the frequency to provide service for it.

[0254] The UE requests to wake up a cell and indicates the index of the cell. If the UE expects to wake up a certain SCell or candidate cell, or the UE expects a certain cell to provide service for it, the MAC CE carries the index of the cell. The MAC CE may carry one or more cell indexes; alternatively, the MAC CE carries a bitmap, each bit corresponds to a cell. If a bit is 1, the corresponding cell is the SCell or candidate cell that the UE expects to wake up, or the cell that the UE expects to provide service for it.

[0255] The UE requests to wake up a certain frequency and indicates the index of the frequency. If the UE expects to wake up a certain frequency, or the UE expects a certain frequency to provide services for it, the MAC CE carries the index of the frequency. The MAC CE can carry one or more frequency indexes; or, the MAC CE carries a bitmap, each bit corresponds to a frequency. If a bit is 1, the corresponding frequency is the frequency that the UE expects to wake up, or the frequency that the UE expects to provide services for it.

[0256] The number of cells that the UE requests to wake up. If the UE expects to wake up one or several SCells or candidate cells, or the UE expects one or several cells to provide services for it, the MAC CE carries the number of cells; the UE's expected data volume or data rate. The UE can predict the amount of data arriving and calculate the amount of data or data rate that needs to be transmitted. The MAC CE carries the data volume or data rate.

[0274] Example 7 (Response)

[0275] The process of UE sending WUS may include:

[0276] S1: The UE meets certain conditions and needs to send a wake-up signal or MAC CE to trigger the wake-up process. Specifically, the RRC layer can instruct the MAC layer to trigger the wake-up process.

[0277] S2: The UE sends a wake-up signal or MAC CE. Specifically, at the MAC, the MAC triggers the PHY to send a wake-up signal such as PUCCH, SR, SRS, or PRACH; or the MAC sends a wake-up MAC CE.

[0278] S3: The UE receives a response signal or MAC CE. Specifically, at the MAC, the MAC starts a timer and waits for a response signal or MAC CE to be received within a specified time window. If the PHY receives the response signal, the PHY indicates this to the MAC, which considers the reception successful. Alternatively, if the MAC receives a response MAC CE, the MAC considers the reception successful.

[0279] S4: If the UE successfully receives the response signal or MAC CE, the UE receives the reference signal according to the instruction.

[0280] After receiving the wake-up signal, the PCell, SCell, or candidate cell can send a response signal, message, or MAC CE to the UE to confirm the transmission of the reference signal. This can be done in one of the following ways:

[0281] Method 1: If the wake-up signal is PRACH, the response signal is RAR. If the UE sends a PRACH wake-up signal, the UE monitors the RAR within the RAR window. The RAR may carry at least one of the following:

[0286] Time when the awakened cell sends the reference signal: the time interval between the UE receiving the RAR and the awakened cell sending the reference signal, or the time interval between the RAR taking effect and the awakened cell sending the reference signal.

[0287] Mode 2: If the wake-up signal is a PUCCH / SRS / SR / MAC CE / RRC message, the response signal is a PDCCH; if the UE sends a wake-up signal or message or MAC CE of a PUCCH / SRS / SR / MAC CE / RRC message, the UE monitors the PDCCH within a time window. The PDCCH may carry at least one of the following:

[0288] Cell wake-up indication: SCell or candidate cell is woken up and sends reference signal;

[0289] Wake-up cell index: the index of the cell that is woken up or sends the reference signal, which can be the index of one cell or multiple cells;

[0296] Wake-up cell index: the index of the cell that is woken up or sends the reference signal, which can be the index of one cell or multiple cells;

[0297] Wake-up cell bitmap: A bitmap where each bit corresponds to a cell. If a bit is 1, the corresponding cell is woken up.

[0298] Cell wake-up failure indication: SCell or candidate cell is not woken up and does not send reference signals;

[0299] Resources for sending reference signals, such as the BWP index, frequency domain resources, and time domain resources for sending reference signals;

[0300] Time when the awakened cell sends the reference signal: the time interval between the UE receiving the MAC CE and the awakened cell sending the reference signal, or the time interval between the MAC CE taking effect and the awakened cell sending the reference signal.

[0301] Mode 4: If the wake-up signal is PUCCH / SRS / SR / MAC CE / RRC message, the response signal is the reference signal of the SCell; if the UE sends a wake-up signal or message or MAC CE of PUCCH / SRS / SR / MAC CE / RRC message, the UE measures the reference signal of the SCell or candidate cell within a time window.

[0302] Example 8 (certain conditions)

[0303] When certain conditions are met, the UE sends a wake-up signal, MAC CE, or RRC message. The conditions include at least one of the following:

[0304] The UE's traffic volume increases, for example, the UE establishes a bearer;

[0305] The UE's service cannot meet the QoS requirement. For example, the rate of a certain bearer of the UE is lower than the rate threshold in the QoS, or the delay of a certain bearer of the UE is higher than the delay threshold in the QoS.

[0306] The amount of data estimated / to be transmitted by the UE exceeds a threshold. For example, the estimated number of uplink data packets arriving by the UE exceeds a threshold, or the amount of uplink data to be transmitted by the UE exceeds a threshold.

[0307] The channel quality of the UE is lower than a threshold. For example, the channel quality of the UE in the PCell is lower than a threshold.

[0308] Example 9 (UE behavior after sending WUS)

[0309] If the UE does not receive a response after sending a wake-up signal, the UE's actions include at least one of the following:

[0310] Method 1: If the wake-up signal is PRACH and the response signal is RAR; if the MAC does not receive the RAR, it initiates the RACH process again. If the number of RACH transmissions reaches a certain threshold, the MAC notifies the RRC that the wake-up process has failed.

[0311] Alternatively, when the MAC triggers the wake-up process for the first time, it starts a timer. During the timer period, the MAC can trigger the wake-up process multiple times. If the timer times out and the MAC has not received the RAR, the MAC indicates to the RRC that the wake-up process has failed.

[0312] Method 2: If the wake-up signal is PUCCH / SRS / SR / MAC CE, the response signal is PDCCH. If the MAC does not receive PDCCH, it triggers the transmission of PUCCH / SRS / SR / MAC CE. If the number of transmissions reaches a certain threshold, the MAC notifies the RRC that the wake-up process has failed.

[0313] Alternatively, when the MAC triggers the wake-up process for the first time, it starts a timer. During the timer period, the MAC can trigger the wake-up process multiple times. If the timer times out and the MAC has not received the PDCCH for the wake-up response, the MAC indicates to the RRC that the wake-up process has failed.

[0314] Mode 3: If the wake-up signal is PUCCH / SRS / SR / MAC CE, the response signal is MAC CE; if MAC does not receive MAC CE, MAC triggers the transmission of PUCCH / SRS / SR / MAC CE. If the number of transmissions reaches a certain threshold, MAC instructs RRC that the wake-up process has failed;

[0315] Alternatively, when the MAC triggers the wake-up process for the first time, it starts a timer. During the timer period, the MAC can trigger the wake-up process multiple times. If the timer times out and the MAC has not received the MAC CE of the wake-up response, the MAC indicates to the RRC that the wake-up process has failed.

[0316] Mode 4: If the wake-up signal is a PUCCH / SRS / SR / MAC CE / RRC message, the response signal is the SCell reference signal; if the UE sends a wake-up signal or message or MAC CE of a PUCCH / SRS / SR / MAC CE / RRC message, the UE measures the SCell reference signal within a time window.

[0317] Alternatively, when the MAC triggers the wake-up process for the first time, it starts a timer. The MAC can trigger the wake-up process multiple times within the timer period. If the timer expires and the MAC has not received the reference signal from the SCell, the MAC notifies the RRC that the wake-up process has failed.

[0318] Mode 5: If the wake-up signal is an RRC message and the response signal is an RRC message; if the RRC sends an RRC message wake-up message but does not receive an RRC message wake-up response within a time window, the RRC considers the wake-up process to have failed.

[0319] Mode 6: If the RRC determines that the wakeup process has failed, or if the RRC receives an indication that the wakeup process has failed, the RRC sends an RRC message to the PCell indicating that the wakeup process has failed. The RRC message can be Failure Information, UEAssistanceInformation, or other messages. The RRC message carries at least one of the following:

[0320] Wake-up failure indication;

[0321] The identity or index of the cell where the wake-up failed;

[0322] Frequency or frequency index where wakeup failed.

[0323] Example 10 (Exchange between gNBs)

[0328] Whether the cell / frequency supports the sleep state, for example, whether the cell supports the sleep state, whether the cell supports not sending reference signals;

[0329] Whether the cell / frequency supports being woken up;

[0330] Configuration of wake-up signals: for example, index, configuration of wake-up signals (such as PUCCH, SR, SRS or PRACH), including configuration of time-frequency resources;

[0331] The cell / frequency is successfully awakened, for example: the UE successfully wakes up the cell / frequency;

[0332] The identifier and index of the cell / frequency that was successfully woken up;

[0335] UE ID: The ID of the UE that sends the wake-up cell / frequency process, or the ID of the UE that is configured with the wake-up cell / frequency configuration.

[0336] Typically, to save power, the base station turns off signals on some cells, such as common channels (such as SIBs). When the UE needs to access these cells, the UE can wake up these cells and the base station can turn on signal transmission for these cells. Possible methods include:

[0337] Method 1 includes at least the following steps:

[0356] S2: In idle or inactive state, the UE obtains the public information of cell B from cell A; the UE can initiate the on-demand system information acquisition process

[0357] S3: When the UE initiates MO, it evaluates cell reselection. If cell B meets the conditions, the UE reselects to cell B and initiates a RACH process in cell B to wake up cell B.

[0360] S2: In idle or inactive state, the UE obtains the public information of cell B from cell A; the UE can initiate the on-demand system information acquisition process

[0361] S3: After receiving the paging message, the UE evaluates cell reselection. If cell B meets the conditions, the UE reselects to cell B and initiates a RACH process in cell B to wake up cell B.

[0362] Cell A broadcasts or configures the wake-up signal (such as PRACH). The configuration includes at least one of the following:

[0368] S3: The UE receives a response signal, such as an RAR, in cell A. Specifically, the MAC starts a timer to receive a response signal within a certain time window. If the MAC receives a response, it considers the reception successful.

[0374] S4: If the UE successfully receives the response signal, the UE receives the common channel in cell B according to the instruction.

[0375] After receiving the wake-up signal, cell A or cell B can send a response signal to the UE to confirm the transmission of the reference signal. This may be one of the following methods:
