In some implementations, the wake-up signal for different purposes corresponds to different preambles.

[0103] - Uplink wake-up signal receiving node: Used to inform the receiving node of the uplink wake-up signal. After receiving this information, the UE can send an uplink wake-up signal to the receiving node.

[0104] The receiving node of the uplink wake-up signal may include one or more of the following: gNBDU where the energy-saving cell is located, gNB CU where the energy-saving cell is located, node where the energy-saving cell is located, gNB DU where the normal cell is located, gNB CU where the normal cell is located, node where the normal cell is located, cell identifier of the normal cell, cell identifier of the energy-saving cell, etc.

[0105] - Receiving cell of uplink wake-up signal: This information is used to inform the UE of the receiving cell of the uplink wake-up signal. After receiving this information, the UE can send an uplink wake-up signal to the receiving cell.

[0106] The receiving node of the uplink wake-up signal may include one or more of the following: energy-saving cell (identifier and / or identification list), normal cell (identifier and / or identification list).

[0107] - Time information for wake-up: This information indicates the time at which a node can be woken up from power-saving mode using an uplink wake-up signal, and / or the time at which a request is made for the node to send SIB1 information.

[0108] For example, an uplink wake-up signal could be sent only within the time period indicated by the time information.

[0109] - Time information indicating when wake-up is not possible: This indicates the time when the node cannot be woken up from power-saving mode using the uplink wake-up signal, and / or when a request is made for the node to send SIB1 information.

[0110] Information. For example, an uplink wake-up signal cannot be sent within the time indicated by this time information. - Start identifier: Used to indicate the start of waking the node from power-saving state using the uplink wake-up signal, and / or to request the node to send SIB1 information.

[0111] - End flag: Used to indicate that the node is no longer being woken up from power-saving state using the uplink wake-up signal, and / or to request the node to send SIB1 information.

[0112] -Time information for retransmitting the uplink wake-up signal: Indicates the time after the user sends the uplink wake-up signal.

[0113] If SIB1 information is not received within the specified time period, the uplink wake-up signal can be retransmitted. Alternatively, if the user fails to send the uplink wake-up signal and / or does not receive SIB1 information after sending the uplink wake-up signal, the uplink wake-up signal needs to be retransmitted after the specified time period. Alternatively, the uplink wake-up signal can only be retransmitted within the time period indicated by the specified time period; it cannot be retransmitted outside of the specified time period.

[0114] - Maximum number of times to send uplink wake-up signals: This indicates that when the number of times a user sends uplink wake-up signals is equal to or greater than this maximum number, the user will stop sending uplink wake-up signals to this cell.

[0115] For example, it means that when the number of times a user sends an uplink wake-up signal is equal to or greater than this maximum value, the user will no longer send an uplink wake-up signal to this cell, but can send uplink wake-up signals to other cells.

[0116] - Activation of other cell time information: In one implementation, for example, if the SIB1 information of the cell corresponding to the uplink wake-up signal cannot be obtained within the time indicated by the time information, an uplink wake-up signal corresponding to another cell is sent to other cells outside the time indicated by the time information to wake up the other cells. In another implementation, for example, an uplink wake-up signal corresponding to another cell is sent to other cells to wake up the other cells within the time indicated by the time information.

[0125] The requesting node sends SIB1 normally, decreases the SIB1 sending period, increases the SIB1 sending period, sends an SSB, activates an SSB, sends an SSB normally, decreases the SSB (burst set) period, and increases the SSB (burst set) period. In some implementations, the wake-up signals for different purposes correspond to different preambles, and the message receiving node can determine the corresponding purpose based on the preamble.

For example, in one implementation, the first node may be the gNB DU of an energy-saving cell, the second node may be the gNB CU of an energy-saving cell, the third node may be the gNB CU of a normal cell, and the fourth node may be the gNB DU of a normal cell.

[0196] Method C:

[0197] Step 501A.c1: The first node sends a seventh message containing a request for uplink wake-up signal configuration to the second node.

The stop can also request and / or instruct the message receiving node to release the uplink wake-up signal configuration; for example, the message receiving node releases the uplink signal configuration after receiving the stop. The stop can also indicate cancellation of uplink wake-up signal configuration transmission; for example, the message receiving node cancels the transmission of uplink wake-up signal configuration after receiving the stop, and / or releases the uplink wake-up signal configuration. For example, if this information is modify and / or update, the message receiving node modifies and / or updates the stored uplink wake-up signal configuration. If the message is a release, the message receiving node releases the uplink signal configuration. If the message is a cancellation, the message receiving node cancels the transmission of the uplink wake-up signal configuration and / or releases the uplink wake-up signal configuration.
