In the following description, although numerous features may be specified as optional, it should be acknowledged that all features included in the independent claims should not be considered optional.

[0096] The above and other aspects and their embodiments will be described in more detail in the accompanying drawings, specification and claims.

[0102] In this disclosure, a cell A with specific area coverage may be a cell that supports energy-saving mode and / or a cell that is in energy-saving mode. Furthermore, a cell in energy-saving mode may be referred to as an "energy-saving cell".

[0103] In this disclosure, cell B refers to a neighboring cell of cell A or a (neighboring) cell on a neighboring frequency of cell A.

[0104] In this disclosure, a synchronization signal may refer to a synchronization signal or a signal used for synchronization.

[0105] How to revitalize energy-efficient communities

[0106] In one embodiment, if / when cell A has coverage in a certain area, cell A may consider entering an energy-saving state / mode. For example, in the case of low load or no serving terminals, cell A may choose to reduce transmission on common channels (e.g., sending SSB or synchronization signals or DRS at longer intervals). When / if a terminal (e.g., UE) moves to cell A or there is a service that needs to be served, cell A needs to restore normal signal transmission and reception. That is, the terminal needs to wake up cell A.

[0107] In one embodiment, cell A needs to resume normal signal transmission and reception and / or exit / leave energy-saving state / mode when / if one or more of the following conditions are met:

[0108] - When / if the UE sends a WUS (Wake-up Signal) and cell A receives the WUS, cell A needs to resume normal signal transmission and reception. In one embodiment, the WUS can be a new WUS signal or a PRACH (Physical Random Access Channel).

[0109] - When / if the core network sends a paging message to the base station and cell A needs to send a paging message, cell A needs to restore normal signal transmission and reception. Specifically, when / if the core network sends a paging message to the base station, the paging message carries cell information, and the corresponding cell needs to send a paging message. For example, the paging message carries a list of cells indicating which cells need to send paging messages. Alternatively, when / if the core network sends a paging message to the base station, the paging message carries cell information, and the corresponding cell does not need to send a paging message. For example, the paging message carries a list of cells indicating which cells do not need to send paging messages. If the core network instructs cell A to send a paging message, then cell A needs to restore normal signal transmission and reception.

[0110] WUS Configuration

[0111] When / if cell A has coverage of a certain area, cell A can consider energy saving. In the case of low load or no serving terminal, cell A can be turned off or selected to transmit signals to reduce MIB or SIB1, or transmit SSB, synchronization signals or DRS at greater intervals. In order to allow the UE to quickly wake up cell A, at least one of the actions / operations in the following embodiments can be adopted.

[0112] In one embodiment, a cell can configure (UL)WUS or energy-saving information of neighboring cells via SIB broadcast or via RRC. For example, cell B can broadcast information from cell A, wherein the broadcast information may include at least one of the following information and / or indication fields: whether cell A supports UL WUS signals, whether cell A supports long-period SSB or synchronization signals or DRS, whether cell A supports energy-saving status, whether cell A does not send PBCH or SIB1, whether cell A is disabled, or the time-frequency resource configuration (e.g., start time, period, duration, etc.) of ULWUS signals or long-period SSB or synchronization signals or DRS in energy-saving status / mode.

[0113] In one embodiment, a cell may broadcast WUS or energy-saving information for adjacent frequencies via SIB or via RRC. For example, cell B broadcasts information for frequency A, which may include at least one of the following information and / or indication fields: whether frequency A supports UL WUS signals, whether frequency A supports energy-saving status, whether frequency A is disabled, or the time-frequency resource configuration of UL WUS (e.g., start time, period, duration, etc.).

[0114] In one embodiment, the serving cell enables the UE to wake up the cell via an RRC message or an SIB. Specifically, the cell uses an RRC message (e.g., an RRC release message) to carry the WUS configuration and enable the UE to transmit the WUS. The WUS configuration may include the frequency domain resource location of the WUS (e.g., bandwidth and frequency), the time domain resource configuration of the WUS (e.g., transmission time and period), and the code domain resource configuration of the WUS. After receiving the RRC message, the UE enables the WUS resources. If the conditions for transmitting the WUS are met, the UE determines that the WUS can be transmitted and / or can be transmitted. Alternatively, if the serving cell is in an energy-saving state and one or more conditions for transmitting the WUS are met, the UE determines that the WUS can be transmitted and / or can be transmitted.

[0115] In one embodiment, the cell indicates the valid area of ​​WUS or a list of cells supporting WUS via an RRC message or SIB. Specifically, the cell uses an RRC message (e.g., an RRC release message) to carry the limited area of ​​WUS or the list of cells supporting WUS. For example, the limited area of ​​WUS can be at least one of a cell list, a frequency list, or a list of area identifiers. One or more cells can belong to the same area and broadcast the same area identifier. After the UE receives the RRC message, if one or more conditions for transmitting WUS are met within the limited area of ​​WUS or within the list of cells supporting WUS, the UE determines that WUS can be transmitted. In this embodiment, WUS cannot be transmitted outside the limited area of ​​WUS or outside the list of cells supporting WUS.

[0116] In one embodiment, the cell indicates the validity period of the WUS via an RRC message, or indicates that the validity period becomes valid when a received RRC message indicates the configuration of the WUS. Specifically, the validity period takes effect when / if the cell uses an RRC message (e.g., an RRC release message) to carry the validity period of the WUS, or when / if the cell indicates the configuration of the WUS (including the WUS's time-frequency resources, valid area, etc.) via an RRC message. After receiving the WUS configuration, the UE starts a timer, and the length of the timer is the validity period of the WUS. While the timer is running, the WUS configuration indicated by the RRC takes effect and / or becomes valid. If one or more conditions for sending the WUS are met, the UE determines that the WUS can be sent and / or the UE can transmit the WUS. When the timer expires, the WUS configuration indicated by the RRC becomes invalid, and the UE releases the WUS configuration indicated by the RRC. If the system information broadcast / includes the WUS configuration, the UE reads and applies the WUS configuration from the system information.

[0117] Conditions for sending WUS

[0118] In one embodiment, the conditions for sending WUS include at least one of the following:

[0119] When the UE detects the SSB, synchronization signal, or DRS signal of a cell, but does not detect the MIB or SIB1 of the cell, the UE may not block the cell for a certain period of time. In this way, the UE can continue to measure the cell and detect in a timely manner whether the cell has exited power-saving mode. After a period of time, if the UE still fails to detect the MIB or SIB1, the UE may block the cell.

[0120] When the UE detects the SSB, synchronization signal, or DRS of a cell but does not detect the MIB or SIB1, the UE lowers the priority of that cell for a certain period, for example, to the lowest priority for a certain time period. In this way, the UE can continue to measure the cell and detect in a timely manner whether the cell has exited power-saving mode. After the certain period, if the UE still fails to detect the MIB or SIB1, the UE can disable the cell.

[0121] When the UE searches for the cell's synchronization signal or DRS and does not detect MIB or SIB1, the UE sends a WUS. In this way, the UE can wake up the energy-efficient cell.

[0122] - When the UE searches for the cell's SSB, synchronization signal, or DRS and does not detect the MIB or SIB1, and the cell is on a high-priority frequency, the UE sends a WUS. In this way, the high-priority frequency is the frequency on which the UE is most likely to camp, and the UE can use the high-priority frequency to wake up the cell.

[0123] - When the UE searches for the SSB, synchronization signal, or DRS of a cell and does not detect the MIB or SIB1, and the cell's measurement (e.g., received signal strength) is the highest value at that frequency or all frequencies or exceeds a certain threshold, the UE sends WUS; in this way, the UE can wake up the strongest cell.

[0124] When the UE searches for the SSB, synchronization signal, or DRS of a cell but does not detect the MIB or SIB1, and the cell's priority based on the reselection criteria is the highest or exceeds a certain threshold, the UE sends a WUS. In this way, the UE can wake up the cell with the highest priority.

[0125] - For frequencies or cells supported by a registered or equivalent PLMN, if the UE searches for a cell's SSB, synchronization signal, or DRS and does not detect a MIB or SIB1, and the UE does not select a cell from a registered or equivalent PLMN or a cell with the highest priority frequency, the UE will send WUS to the registered or equivalent PLMN frequency. For a found cell, the UE sends WUS. In this way, the UE can wake up a registered or equivalent PLMN cell and camp on that cell.

[0126] - For frequencies supported by a registered or equivalent PLMN, when the UE fails to find a cell on the highest priority frequency, the UE will send WUS on the highest priority frequency of the registered or equivalent PLMN. In this way, the UE can wake up a cell with the highest priority frequency of the registered or equivalent PLMN and camp on that cell.

[0127] - For frequencies supported by a registered or equivalent PLMN, the UE does not select a cell under the registered or equivalent PLMN. The UE can send WUS messages from high to low frequency priority based on the frequencies under the registered or equivalent PLMN. In this way, the UE can wake up a registered or equivalent PLMN cell and camp on that cell.

[0128] - If the UE is already camped on a frequency cell or highest priority cell supported by a registered or equivalent PLMN, the UE stops sending WUS.

[0129] - For frequencies or cells where the UE supports a RAT or has the same RAT or NR, if the UE searches for the cell's SSB, synchronization signal, or DRS and does not detect a MIB or SIB1 on the highest priority frequency, the UE will send WUS to the frequency or cell where the UE supports the RAT. That is, if the UE searches for the cell's SSB, synchronization signal, or DRS and does not detect a MIB or SIB1 on the highest priority frequency, the UE can send WUS on a frequency or cell that supports the same RAT (e.g., NR) supported by the UE. In this way, the UE can wake up and camp on a cell that supports the same RAT.

[0130] - For frequencies of the RAT supported by the UE, or frequencies of the same RAT or NR supported by the UE, when / if the UE does not find a cell, the UE transmits WUS from high to low according to the frequency priority of the RAT supported by the UE. In this way, the UE can wake up a cell that supports the UE's RAT and camp on that cell.

[0131] - If the UE is already camped in a supported RAT cell or the highest priority cell, the UE stops sending WUS.

[0132] - For frequencies or cells supported or stored by the UE, if the UE does not find a cell or does not find a cell on the highest priority frequency or cell, the UE sends WUS messages from high to low based on the frequency priority of the supported or stored frequencies or cells. In this way, the UE can wake up a cell on a supported frequency and camp on that cell.

[0133] - If the UE has already found a cell with the highest priority frequency, the UE stops sending WUS.

[0134] - If the UE is in any cell selection state, the UE transmits WUS based on its supported frequencies or RATs. In this embodiment, the UE is in any cell selection state and cannot find a suitable cell to camp on its supported frequencies or RATs. The UE transmits WUS from high to low frequency priority based on its supported frequencies or RATs, and the UE can camp on all supported frequencies or RATs within a cell.

[0135] - When the UE has uplink traffic, the UE sends a WUS. After cell A receives the WUS, cell A needs to resume normal signal transmission and reception. Specifically, the UE sends a WUS when / if the UE's NAS instructs the RRC to establish an RRC connection, or when / if the NAS instructs the RRC or MAC to send a WUS, or when / if the RRC sends a WUS before sending an RRC message, etc.

[0136] When the UE can move to the edge of a cell, it can send a WUS to wake up surrounding cells. Specifically, when the UE is camped on cell B and the measured RSRP / RSRQ values ​​are less than a threshold and / or the change in RSRP / RSRQ over a certain period of time is greater than a threshold, the UE can send a WUS to wake up cell A.

[0137] When the UE may move to the edge of a cell, the UE can send a WUS to wake up the cell. Specifically, if the UE detects that the measurement value of cell A is higher than a certain threshold, or if the measurement result of cell A is the highest at that frequency, the UE sends a WUS to wake up cell A.

[0138] - When information about neighboring cells is not broadcast within the cell, the UE cannot search for the SSB, synchronization signal, or DRS of neighboring cells, and the UE cannot know whether neighboring cells exist. In this case, the UE does not send a WUS. Specifically, cell B does not broadcast the existence of cell A. When the UE cannot find the SSB, synchronization signal, or DRS of cell A, the UE does not send a WUS.

[0139] When the UE finds the synchronization signal or DRS of a cell but cannot detect the MIB or SIB1, the UE does not maintain the cell configuration and prioritizes sending WUS. Specifically, the UE finds the synchronization signal or DRS of cell A but cannot detect the MIB or SIB1. The UE cannot know whether the cell supports UL WUS / DRS / energy saving, and the UE sends WUS to wake up cell A.

[0140] Actions after sending WUS

[0141] If the UE sends WUS, the UE can perform certain actions or behave in certain ways.

[0142] In one embodiment, if the cell's MIB, SIB, or SSB is detected within a certain period after WUS transmission, the UE can perform certain actions. If the cell's MIB, SIB, or SSB is detected, the UE considers the cell to have been woken up and resumes normal signal transmission and reception. Otherwise, the UE considers / determines that the cell's wake-up has failed.

[0143] In one embodiment, if the UE fails to detect the cell's MIB, SIB, or SSB within a certain period after sending WUS, the UE will not block the cell. In this embodiment, the UE can resend WUS. Specifically, the UE can start a timer after sending WUS. During the timer's execution, the UE monitors / searches for the cell's MIB, SIB, or SSB, and the UE can continue sending WUS. If the timer expires and the UE does not detect the cell's MIB, SIB, or SSB, the UE will not block the cell, and the UE can resend WUS.

[0144] In one embodiment, the UE fails to receive the cell's MIB, SIB, or SSB after multiple WUS sensing attempts. In this embodiment, the UE disables the cell / frequency. For example, the UE can disable the cell or frequency in the following situations:

[0145] - The number of times the UE sends WUS reaches a threshold or the UE has been sending WUS for a certain period of time; and

[0146] - The UE did not find the MIB, SIB or SSB of the cell.

[0147] In one embodiment, the power of each WUS transmitted by the UE is increased by an offset value compared to the power of the previous WUS. Specifically, the UE transmits a WUS with a power of W, and the UE transmits another WUS with a power of W + offset. This can improve the success rate of the base station detecting the WUS.

[0148] WUS auxiliary community

[0149] In some embodiments, a base station deploys one or more cells or frequency bands as SCells (secondary cells). When network load is low, the base station can disable SCells or reduce the transmission and reception of SCell signals (e.g., SSB or PBCH). When network load is high, the base station enables SCells or restores the transmission and reception of SCell signals (such as SSB or PBCH).

[0150] In one embodiment, the primary cell may broadcast or configure SCell power-saving information (such as the cell or frequency configured for idle / active state measurement). Specifically, system information or RRC release messages may include at least one of the following information and / or indication fields: whether the configured SCell supports power saving, whether the configured SCell is in power-saving state, whether the configured SCell supports UL WUS, whether the primary cell supports synchronization signals or DRS, UL WUS time-frequency resource configuration information, SSB, synchronization signal or DRS time-frequency information, or power-saving time information, etc.

[0151] In one embodiment, for a candidate Scell, if the cell transmits an energy-saving related SSB, synchronization signal, or DRS, the UE measures these signals within the cell. When the measurement result reaches / exceeds a certain threshold or is the highest measurement result, the UE sends a WUS to wake up the cell. Specifically, a cell enters an energy-saving state and transmits an SSB, synchronization signal, or DRS for an extended period. The UE measures these signals and obtains the measurement results. When the measurement result reaches / exceeds a certain threshold or is the highest measurement result, that cell can be designated as the UE's Scell, and the UE sends a WUS to wake up the cell.

[0152] In one embodiment, when / if the primary cell adds an SCell and the UE detects synchronization failure, the UE may send a WUS (Warnings to Cells). Specifically, the primary cell adds the SCell to the UE via RRC (Registration Control Code) signaling. Upon receiving the RRC signaling, the UE finds that it cannot obtain synchronization information for the added SCell. In this case, the UE sends a WUS. After receiving the WUS, the SCell sends an SSB (Synchronization Bus). The UE measures the SSB to obtain the SCell's synchronization information.
