[0061] Figure 1 shows a block diagram of a wireless communication system applicable to an embodiment of this application. Specifically, the wireless communication system includes a terminal 11 and a network-side device 12.

[0062] Terminal 11 can also be referred to as User Equipment (UE).

It should be noted that this application embodiment only uses a base station in an NR system as an example for description and does not limit the specific type of base station.

[0065] To facilitate a better understanding of the embodiments of this application, the updates of system information (SI) related to this application are explained.

[0066] If some system parameters of the cell change, for example, some parameters in SIB 1 change, since the UE does not continuously receive SIB 1 at periodic time points, the network side notifies the UE by paging while the current system message is still valid. Unlike LTE, where the UE can obtain the system message change indication by receiving the downlink control information (DCI) of the paging radio network temporary identity (P-RNTI), in LTE, it is necessary to detect the DCI scrambled with the P-RNTI and demodulate and decode it on the Physical Downlink Shared Channel (PDSCH) scheduled by the DCI. After successful decoding, it is then necessary to determine whether there is a system message change indication from the downlink shared channel (DL-SCH).

[0067] Specifically, the DCI carries a Short Messages Indicator and Short Messages. The Short Messages Indicator indicates whether the content in the DCI includes paging scheduling information and whether it contains short messages. For example, the Short Messages Indicator can be shown in Table 1, and the Short Messages can be shown in Table 2.

[0068] Table 1

[0069] Table 2

[0070] After receiving a short message, the terminal executes the SI acquisition procedure in the next modification period. In the next modification period, the UE will first receive SIB1, determine the changed SI based on the configuration in SIB1 (such as value tag), and then receive the corresponding SI.

[0071] To facilitate a better understanding of the embodiments of this application, the NES related to this application will be described.

[0072] The main idea of ​​Network Energy Saving (NES) technology is to reduce unnecessary uplink / downlink, time domain / frequency domain / spatial domain transmissions without affecting terminal services or system performance, so as to achieve the purpose of network energy saving.

[0073] To facilitate a better understanding of the embodiments of this application, the validity of the system messages related to this application is explained.

[0074] Area Validity: Introduced to reduce unnecessary power consumption by the user terminal (UE). The Master Information Block (MIB) and SIB 1 are cell-specific. Other System Information (OSI) can be either cell-specific or area-specific, configured by SIB 1. If area-specific, an Area ID is provided, which is unique within the Public Land Mobile Network (PLMN). The configuration granularity is indicated per SI message.

[0075] OSI value tag: SIB 1 indicates the version of the currently transmitted SIB. If the UE has stored the version of the broadcast SIB locally, the UE does not need to read it repeatedly, reducing UE power consumption. The value tag ranges from 0 to 31.

[0076] Valid for 3 hours: When a UE leaves the cell and returns, if the current value tag is the same as the value tag before leaving, the UE does not know whether it is the same system information. Therefore, it is necessary to define an validity period of 3 hours. By default, there is no problem for UEs that have been camped in the cell, but this rule applies to all UEs.

[0077] Subsequent improvements: Since the UEs that have been camped in this cell have found that the version of this SIB has not changed, but because the 3-hour expiration rule requires re-acquisition, which will cause the UE to consume power, it is stipulated that when the UE verifies the validity of the SIB version within the validity period, this validity period will be extended by 3 hours.

[0078] To facilitate a better understanding of the embodiments of this application, the problems solved by this application will be explained.

[0079] For the legacy mechanism, SIB 1 is sent periodically. For UEs camped in the cell, they can actively read SIB 1 before it expires.

[0080] In network energy-saving scenarios, NES cells send SIB 1 non-periodically to save energy. UEs camped in NES cells cannot request SIB 1 based on the WUS configuration in the already invalid SIB 1.

[0081] The wireless communication method provided in this application will be described in detail below with reference to the accompanying drawings and through some embodiments and application scenarios.

[0082] Figure 2 is a schematic flowchart of a wireless communication method 200 according to an embodiment of this application. As shown in Figure 2, the wireless communication method 200 may include at least some of the following:

[0083] S210, the terminal receives the SIB of the first cell in the first cell or the second cell;

[0084] Wherein, the first cell is a cell that sends SIBs on demand, or the first cell is a cell that does not actively send SIBs, or the first cell is a cell that sends SIBs non-periodically.

[0085] The second cell is the cell that periodically sends SIBs;

[0086] S220, after the terminal camps on the first cell, it receives the SIB of the first cell from the first cell; or, after the terminal camps on the first cell, the terminal assumes that the first cell is not allowed to be camped on and performs cell reselection.

[0087] It should be understood that Figure 2 illustrates the steps or operations of the wireless communication method 200, but these steps or operations are merely examples, and other operations or variations of the various operations in Figure 2 may also be performed in this application.

[0088] The System Information Block (SIB) described in this application embodiment can be a single SIB (such as SIB 1) or at least two SIBs (such as one or more of SIB 1-SIB X, or a combination of more of SIB 1-SIB X). This application embodiment does not limit this.

[0089] The cell described in this application embodiment can be equivalent to or replaced by carrier, serving cell, bandwidth part (BWP), TRP, etc., and this application embodiment does not limit this.

[0090] The transmission or adjustment of SIBs described in the embodiments of this application can be understood as: the transmission of SIBs from not transmitting to transmitting, or from transmitting SIBs in a large period to transmitting SIBs in a small period, or from not transmitting SIBs to transmitting SIBs periodically, etc.

[0091] The uplink signal described in this application embodiment can be a WUS signal or an on-demand signal.

[0092] In this embodiment of the application, the first cell is a Network Energy Saving (NES) cell. For example, an NES cell is a cell that sends SIBs on demand, or an NES cell that does not actively send SIBs, or an NES cell that sends SIBs non-periodically.

[0093] For example, taking the first cell as NES cell and SIB as SIB 1, the NES cell sends SIB1 non-periodically to save energy. Terminals residing in the NES cell cannot request SIB 1 based on the WUS configuration in the already invalid SIB 1.

[0094] In this embodiment, the first cell is a cell that sends SIBs on demand, or a cell that does not actively send SIBs, or a cell that sends SIBs non-periodically. After the terminal camps on the first cell, it receives the SIB of the first cell from the first cell. In other words, after the terminal camps on the first cell, it can re-receive the SIB of the first cell to update the SIB of the first cell previously received in the first cell or the second cell, thereby ensuring the validity of the SIB of the first cell obtained by the terminal. This avoids the terminal being unable to request the SIB based on the relevant configuration in the failed SIB after the SIB of the first cell received in the first cell or the second cell becomes invalid, and ensures that the terminal can normally receive the SIB of the first cell.

[0095] Alternatively, in this embodiment, the first cell is a cell that sends SIBs on demand, or a cell that does not actively send SIBs, or a cell that sends SIBs non-periodically. After the terminal camps on the first cell, the terminal assumes that the first cell is not allowed to be camped on, and the terminal performs cell reselection (such as reselecting to the second cell) to avoid the terminal being unable to request SIBs based on the relevant configuration in the failed SIBs after the SIBs received by the terminal in the first cell or the second cell have failed.

[0096] In some embodiments, the SIB of the first cell includes the configuration corresponding to the first uplink signal (such as the WUS configuration);

[0097] The configuration corresponding to the first uplink signal includes at least one of the following:

[0098] The transmission configuration of the first uplink signal;

[0099] The SIB reception configuration of the first cell;

[0100] The configuration for receiving the feedback signal corresponding to the first uplink signal;

[0101] The configuration of search space 0 for the first cell;

[0102] The configuration of control resource set 0 in the first cell.

[0103] For example, the search space 0 of the first cell can be used to receive the SIB of the first cell.

[0104] For example, the control resource set 0 of the first cell can be used to receive the SIB of the first cell.

[0105] Optionally, the first uplink signal is used by the terminal to request the transmission or adjustment of the SIB of the first cell.

[0106] In this embodiment, the terminal can obtain the configuration corresponding to the first uplink signal based on the SIB of the first cell. The configuration corresponding to the first uplink signal includes at least one of the following: the transmission configuration of the first uplink signal, the reception configuration of the SIB of the first cell, the reception configuration of the feedback signal corresponding to the first uplink signal, the configuration of the search space 0 of the first cell, and the configuration of the control resource set 0 of the first cell. Therefore, the terminal can transmit the first uplink signal based on the transmission configuration of the first uplink signal, receive the SIB of the first cell based on the reception configuration of the SIB of the first cell, receive the feedback signal corresponding to the first uplink signal based on the reception configuration of the feedback signal corresponding to the first uplink signal, receive the SIB of the first cell based on the configuration of the search space 0 of the first cell, and receive the SIB of the first cell based on the configuration of the control resource set 0 of the first cell.

[0107] In some embodiments, the wireless communication method 200 further includes:

[0108] The terminal transmits a first uplink signal in the first cell, wherein the first uplink signal is used by the terminal to request the transmission or adjustment of the SIB in the first cell; or...

[0109] The terminal sends a second uplink signal in the second cell; wherein the second uplink signal is used by the terminal to request the transmission or adjustment of the SIB of the first cell in the second cell.

[0110] For example, before the terminal receives the SIB of the first cell in the first cell, the terminal sends the first uplink signal in the first cell.

[0111] For example, before the terminal receives the SIB of the first cell in the second cell, the terminal sends the second uplink signal in the second cell.

[0112] In some embodiments, the configuration corresponding to the first uplink signal is carried by one of the following:

[0117] In some embodiments, the wireless communication method 200 further includes:

[0118] The terminal receives a first feedback signal, wherein the first feedback signal is a feedback signal corresponding to the first uplink signal, or the first feedback signal is a feedback signal corresponding to the second uplink signal.

[0119] For example, the terminal receives the first feedback signal from the first cell. In this case, the first feedback signal is the feedback signal corresponding to the first uplink signal.

[0120] For example, the terminal receives the first feedback signal from the second cell. In this case, the first feedback signal is the feedback signal corresponding to the second uplink signal.

[0121] In some embodiments, the above-described S210 may specifically include:

[0122] The terminal starts a first timer and receives the SIB of the first cell from the first cell or the second cell during the operation of the first timer;

[0123] The start time of the first timer is associated with the first feedback signal.

[0124] In this embodiment, the terminal starts a first timer and receives the SIB of the first cell from the first cell or the second cell during the operation of the first timer, so as to avoid the terminal receiving the SIB of the first cell from the first cell or the second cell for a long time, and to avoid the first cell or the second cell transmitting the SIB of the first cell for a long time, so as to achieve energy saving of the terminal and energy saving of the first cell or the second cell.

[0147] After the terminal fails to send the first uplink signal, the terminal re-confirms whether the triggering conditions for the first uplink signal are met; if the triggering conditions are met, the terminal retransmits the first uplink signal; if the triggering conditions are not met, the terminal terminates the random access procedure, or the terminal terminates the process of requesting the SIB of the first cell; or...

[0148] After the terminal fails to send the second uplink signal, the terminal reconfirms whether the triggering conditions for the second uplink signal are met; if the triggering conditions for the second uplink signal are met, the terminal retransmits the second uplink signal; if the triggering conditions for the second uplink signal are not met, the terminal terminates the random access procedure, or the terminal terminates the process of requesting the SIB of the first cell.

[0149] In some embodiments, the wireless communication method 200 further includes:

[0150] After the terminal sends the first uplink signal, if no feedback signal corresponding to the first uplink signal is received, the terminal reconfirms whether the triggering condition of the first uplink signal is met; if the triggering condition of the first uplink signal is met, the terminal retransmits the first uplink signal; if the triggering condition of the first uplink signal is not met, the terminal terminates the random access procedure, or the terminal terminates the process of requesting the SIB of the first cell; or...

[0151] After the terminal sends the second uplink signal, if no feedback signal corresponding to the second uplink signal is received, the terminal reconfirms whether the triggering condition of the second uplink signal is met; if the triggering condition of the second uplink signal is met, the terminal resends the second uplink signal; if the triggering condition of the second uplink signal is not met, the terminal terminates the random access procedure, or the terminal terminates the process of requesting the SIB of the first cell.

[0152] In some embodiments, the wireless communication method 200 further includes:

[0153] After the terminal sends the first uplink signal or the second uplink signal, and before camping on the first cell, if the SIB of the first cell received or acquired by the terminal is not invalid, the terminal will not trigger the transmission of the first uplink signal or the second uplink signal before camping on the first cell.

[0154] In some embodiments, the wireless communication method 200 further includes:

[0155] The terminal determines whether the SIB of the first cell received or acquired by the terminal is invalid based on the target domain indicated in the configuration corresponding to the first uplink signal; or...

[0156] The terminal determines whether the SIB of the first cell received or acquired by the terminal is invalid based on the target domain indicated in the configuration corresponding to the second uplink signal.

[0157] Optionally, the target domain includes at least one of the following: version number, value tag.

[0158] For example, taking the first cell as the NES cell, the first cell's SIB as OD-SIB 1, and the second cell as cell A, before the UE camps on the NES cell, the WUS configuration received in cell A (such as a cell that periodically sends SIB 1, or cell A being a normal cell) carries the value tag of the NES cell's OD-SIB1 (for example, adding a field: OD-SIB1 value tag in the WUS configuration). If the UE determines that the value tag in the WUS configuration has not changed, it means that the OD-SIB 1 of the NES cell previously obtained by the UE is valid, and even if the WUS triggering condition is met, there is no need to send UL-WUS again; if the value tag has changed, it means that the OD-SIB 1 of the NES cell previously obtained has expired, and if the WUS triggering condition is met, it is necessary to trigger UL-WUS again to request the OD-SIB 1 of the NES cell.

[0159] In some embodiments, the wireless communication method 200 further includes:

[0160] The terminal receives a target message from the first cell, wherein the target message is used to instruct the transmission or adjustment of the SIB of the first cell.

[0161] Specifically, in S220 above, the terminal receiving the SIB of the first cell after camping on the first cell includes:

[0162] The terminal receives the SIB of the first cell from the first cell according to the target message; and / or,

[0163] At the next PDCCH listening opportunity after receiving the target message, the terminal starts listening to type 0 PDCCH, which is used to schedule the SIB of the first cell.

[0164] In this embodiment, the terminal receives the SIB of the first cell from the first cell according to the target message. After camping on the first cell, the terminal can re-receive the SIB of the first cell to update the SIB of the first cell previously received in the first cell or the second cell, thereby ensuring the validity of the SIB of the first cell obtained by the terminal. This avoids the terminal being unable to request the SIB based on the relevant configuration in the failed SIB after the SIB of the first cell received in the first cell or the second cell becomes invalid, and ensures that the terminal can receive the SIB of the first cell normally.

[0165] In this embodiment, after receiving the target message, the terminal starts listening to the type 0 PDCCH at the next PDCCH listening time. The terminal can receive the SIB of the first cell based on the type 0 PDCCH. After camping on the first cell, the terminal can re-receive the SIB of the first cell to update the SIB of the first cell previously received in the first cell or the second cell, thereby ensuring the validity of the SIB of the first cell obtained by the terminal. This avoids the terminal being unable to request the SIB based on the relevant configuration in the failed SIB after the SIB of the first cell received in the first cell or the second cell becomes invalid, and ensures that the terminal can receive the SIB of the first cell normally.

[0166] In some embodiments, the terminal receives the SIB of the first cell from the first cell according to the target message, including at least one of the following:

[0173] The start time of the first time window includes at least one of the following: the next time unit after the terminal receives the target message, the time unit after the terminal receives the target message at an interval of S2 time units, the start position of the next time window or period after the terminal receives the target message, and the time unit when the terminal receives the target message.

[0180] The terminal stops receiving SIBs from the first cell when the fourth timer stops running or ends; or...

[0181] The terminal stops receiving the SIB of the first cell after the first time window ends.

[0182] In some embodiments, the target message includes at least one of the following: a short message and a short message indicator.

[0183] Optionally, the last four bits of the short message are used to indicate at least one of the following: the first cell sends SIBs, the number of SIBs sent by the first cell, the number of time windows or periods for the first cell to send SIBs, the duration of the first cell sending SIBs, whether the first cell sends SIBs periodically, the duration of the fourth timer, and the duration of the first time window.

[0184] In this embodiment, the last four bits of the short message are used to indicate at least one of the following: the first cell sends an SIB, the number of SIBs sent by the first cell, the number of time windows or periods for the first cell to send SIBs, the duration of the first cell sending SIBs, whether the first cell periodically sends SIBs, the duration of the fourth timer, and the duration of the first time window. Specifically, after the terminal camps on the first cell, it can receive the SIB of the first cell from the first cell based on the last four bits of the short message. After the terminal camps on the first cell, it can re-receive the SIB of the first cell to update the SIB of the first cell previously received in the first cell or the second cell, thereby ensuring the validity of the SIB of the first cell obtained by the terminal and avoiding the inability to request the SIB based on the relevant configuration in the failed SIB after the SIB of the first cell received by the terminal in the first cell or the second cell becomes invalid, thus ensuring that the terminal can normally receive the SIB of the first cell.

[0185] Optionally, one or more of the first four bits of the short message are a first specific value, and the last four bits of the short message are used to indicate at least one of the following: the first cell sends SIBs, the number of SIBs sent by the first cell, the number of time windows or periods for the first cell to send SIBs, the duration of the first cell sending SIBs, whether the first cell sends SIBs periodically, the duration of the fourth timer, and the duration of the first time window.

Specifically, after the terminal camps on the first cell, it can receive the SIB of the first cell from the first cell based on the last four bits of the short message. After camping on the first cell, the terminal will overwrite the SIB of the first cell previously received in the first cell or the second cell with the newly received SIB of the first cell, thereby ensuring the validity of the SIB of the first cell obtained by the terminal and avoiding the inability to request SIBs based on the relevant configuration in the failed SIB after the SIB of the first cell received by the terminal in the first cell or the second cell becomes invalid, thus ensuring that the terminal can receive the SIB of the first cell normally.

[0187] Optionally, one or more of the first four bits of the short message are a first specific value, the short message indication is a second specific value, and the last four bits of the short message are used to indicate at least one of the following: the first cell sends SIBs, the number of SIBs sent by the first cell, the number of time windows or periods for the first cell to send SIBs, the duration of the first cell sending SIBs, whether the first cell sends SIBs periodically, the duration of the fourth timer, and the duration of the first time window.

[0188] In this embodiment, one or more of the first four bits of the short message are a first specific value, and the short message indication is a second specific value. The last four bits of the short message are used to indicate at least one of the following: the first cell sends an SIB, the number of SIBs sent by the first cell, the number of time windows or periods for the first cell to send SIBs, the duration of the first cell sending SIBs, whether the first cell periodically sends SIBs, the duration of the fourth timer, and the duration of the first time window. Specifically, after the terminal camps on the first cell, it can receive the SIB of the first cell from the first cell based on the last four bits of the short message. After camping on the first cell, the terminal will overwrite the SIB of the first cell previously received in the first or second cell with the newly received SIB of the first cell, thereby ensuring the validity of the SIB of the first cell obtained by the terminal. This avoids the terminal being unable to request an SIB based on the relevant configuration in the failed SIB after the SIB of the first cell received in the first or second cell becomes invalid, ensuring that the terminal can normally receive the SIB of the first cell.

[0189] Optionally, the short message indication is a second specific value, and the last four bits of the short message are used to indicate at least one of the following: the first cell sends SIBs, the number of SIBs sent by the first cell, the number of time windows or periods for the first cell to send SIBs, the duration of the first cell sending SIBs, whether the first cell sends SIBs periodically, the duration of the fourth timer, and the duration of the first time window.

[0190] In this embodiment, the short message indication is a second specific value. The last four bits of the short message are used to indicate at least one of the following: the first cell sends an SIB, the number of SIBs sent by the first cell, the number of time windows or periods for the first cell to send SIBs, the duration of the first cell sending SIBs, whether the first cell periodically sends SIBs, the duration of the fourth timer, and the duration of the first time window. Specifically, after the terminal camps on the first cell, it can receive the SIB of the first cell from the first cell based on the last four bits of the short message. After camping on the first cell, the terminal will overwrite the SIB of the first cell previously received in the first or second cell with the newly received SIB of the first cell, thereby ensuring the validity of the SIB of the first cell obtained by the terminal. This avoids the terminal being unable to request an SIB based on the relevant configuration in the failed SIB after the SIB of the first cell received in the first or second cell becomes invalid, ensuring that the terminal can normally receive the SIB of the first cell.

[0191] For example, the first specific value is 0 or 1.

[0192] For example, the second specific value is 00.

[0193] In some embodiments, the activation condition for the fourth timer includes the terminal receiving the target message;

[0194] The target message satisfies at least one of the following:

[0195] One or more of the first four bits of the short message in the target message are a first specific value;

[0209] In some embodiments, the target message is a DCI format 1_0 scrambled with a Paging Radio Network Temporary Identity (P-RNTI); or, the target message is a DCI format 1_0 scrambled with a newly added Radio Network Temporary Identity (RNTI).

[0210] In some embodiments, the terminal assumes that the first cell is in a state of periodically transmitting SIBs, and that the terminal periodically receives SIBs from the first cell. Optionally, after the terminal camps on the first cell, the first cell is in a state of periodically transmitting SIBs.

[0211] In this embodiment, after the terminal camps on the first cell, it is assumed that the first cell is in a state of periodically sending SIBs. In other words, after the terminal camps on the first cell, the state of the first cell sending SIBs is changed, such as from a state of sending SIBs on demand to a state of periodically sending SIBs, or from a state of not actively sending SIBs to a state of periodically sending SIBs, or from a state of not sending SIBs to a state of periodically sending SIBs.

[0212] In some embodiments, in S220 above, the terminal assumes that the first cell does not allow camping, including:

[0213] After the SIB of the first cell fails, the terminal assumes that the first cell is not allowed to be camped; or,

[0214] Within K time units before the SIB of the first cell expires, the terminal attempts to receive the SIB of the first cell but fails to receive it. The terminal assumes that the first cell does not allow camping, and K is a positive integer. Optionally, the value of K can be agreed upon by the protocol or configured by the network side.

[0215] In this embodiment, the terminal assumes that the first cell is not allowed to be camped, such as the terminal assuming that the first cell is barred.

[0216] In this embodiment, after the SIB of the first cell fails, the terminal assumes that the first cell is not allowed to be camped (e.g., it is barred), and initiates the cell reselection process to reselect to another cell for service transmission.

[0218] In some embodiments, before the terminal camps on the first cell, the wireless communication method 200 further includes:

[0219] The terminal receives the first configuration and the second configuration in the second cell;

[0220] When the terminal requests the SIB of the first cell on demand, the terminal sends a first uplink signal based on the first configuration, or the terminal sends a second uplink signal based on the second configuration.

[0221] Wherein, the first uplink signal is used by the terminal to request the transmission or adjustment of the SIB of the first cell in the first cell, and the second uplink signal is used by the terminal to request the transmission or adjustment of the SIB of the first cell in the second cell.

[0222] The first configuration described in this embodiment can be referred to as or replaced with the configuration corresponding to the first uplink signal, and the second configuration described in this embodiment can be referred to as or replaced with the configuration corresponding to the second uplink signal.

[0225] The terminal sends the first uplink signal based on the first configuration, or sends the second uplink signal based on the second configuration, depending on whether a service is present; or...

[0226] The terminal sends the first uplink signal by default based on the first configuration, or the terminal sends the second uplink signal by default based on the second configuration;

[0227] The fourth condition includes at least one of the following:

[0228] If the number of failed transmissions of the first uplink signal is greater than or equal to the first threshold, the second uplink signal is transmitted based on the second configuration;

[0229] If the number of failed transmissions of the second uplink signal is greater than or equal to the second threshold, the first uplink signal is transmitted based on the first configuration.

[0230] If the reference signal measurement result of the first cell is within the first interval, the first uplink signal is sent based on the first configuration, or the second uplink signal is sent based on the second configuration;

[0231] If the reference signal measurement result of the second cell is within the second interval, the first uplink signal is sent based on the first configuration, or the second uplink signal is sent based on the second configuration.

[0232] In some implementations, the terminal sends the first uplink signal based on the first configuration or the second uplink signal based on the second configuration, depending on whether a service exists, including:

[0233] When service is available, the terminal sends the first uplink signal based on the first configuration; and / or,

[0234] In the absence of service, the terminal sends the second uplink signal based on the second configuration; and / or,

[0235] When service is available, the terminal sends the first uplink signal based on the second configuration; and / or,

[0236] In the absence of service, the terminal sends the second uplink signal based on the first configuration; and / or.

[0237] In other implementations, the terminal sends the first uplink signal based on the first configuration, or sends the second uplink signal based on the second configuration, depending on whether service is present, including:

[0238] In the absence of service, the terminal sends the first uplink signal based on the first configuration; and / or,

[0239] When a service is in operation, the terminal sends the second uplink signal based on the second configuration.

[0240] Optionally, the first threshold may be agreed upon by the protocol, or the first threshold may be configured by the network side.

[0241] Optionally, the second threshold can be agreed upon by the protocol, or the second threshold can be configured by the network side.

[0242] Optionally, the first interval can be agreed upon by the protocol, or the first interval can be configured by the network side.

[0243] Optionally, the second interval can be agreed upon by the protocol, or the second interval can be configured by the network side.

[0244] Optionally, the reference signal measurement results may include, but are not limited to, at least one of the following: Reference Signal Received Power (RSRP), Reference Signal Received Quality (RSRQ), and Signal to Interference plus Noise Ratio (SINR).

[0245] In some embodiments, the fourth condition may be agreed upon by a protocol, or the fourth condition may be configured by the network side.

[0246] In some embodiments, the first cell is woken up by the second cell via the Xn interface when the fifth condition is met;

[0247] The fifth condition includes, but is not limited to, at least one of the following:

[0248] The terminal requested the SIB of the first cell in the second cell;

[0249] The terminal requests configuration corresponding to the first uplink signal in the second cell. The first uplink signal is used by the terminal to request the transmission or adjustment of the SIB of the first cell.

[0250] The terminal sends a second uplink signal in the second cell, the second uplink signal being used by the terminal to request the transmission or adjustment of the SIB in the first cell in the second cell.

[0251] In some embodiments, the fifth condition may be agreed upon by a protocol, or the fifth condition may be configured by the network side.

[0252] In this embodiment, the terminal receives the SIB of the first cell from either the first cell or the second cell. The first cell may be a cell that transmits SIBs on demand, or a cell that does not actively transmit SIBs, or a cell that transmits SIBs non-periodically, while the second cell transmits SIBs periodically. The terminal receives the SIB from the first cell after camping on it; or, after camping on the first cell, the terminal assumes that the first cell is not allowed to be camped on, and performs cell reselection. Specifically, the first cell may be a cell that transmits SIBs on demand, or a cell that does not actively transmit SIBs, or a cell that transmits SIBs non-periodically. The terminal receives the SIB from the first cell after camping on it, thus ensuring the validity of the SIB obtained by the terminal. This prevents the terminal from being unable to request a new SIB based on the relevant configuration in the failed SIB after receiving it in the first or second cell, ensuring that the terminal can normally receive the SIB from the first cell. Alternatively, after the terminal camps on the first cell, the terminal assumes that the first cell does not allow camping and performs cell reselection to prevent the terminal from being unable to request the SIB based on the relevant configuration in the failed SIB after the SIB received by the terminal in the first cell or the second cell fails.

[0334] The technical solution of this application is described below through specific embodiments.

[0335] Example 1 uses a scenario where the first cell is an NES cell, the second cell is cell A, and the SIB of the first cell is on-demand SIB 1 (OD-SIB 1). In Example 1, the terminal (UE) camps on cell A. The UE sends UL-WUS1 in cell A to obtain the OD-SIB 1 of the NES cell (e.g., the validity period of the NES cell's SIB 1 is 3 hours). The NES cell meets the conditions for cell reselection, the UE performs reselection, reselects to the NES cell, and camps on the NES cell. When the 3 hours are almost up, the OD-SIB 1 of the NES cell obtained by the UE from cell A is about to expire. Before the OD-SIB 1 expires, the UE sends UL-WUS2 again in the NES cell to request the OD-SIB 1 of the NES cell. This solves the problem of the OD-SIB 1 obtained from cell A expiring when the UE camps on the NES cell (without sending SIB 1).

[0336] Optionally, the UE may first send UL-WUS to obtain the OD-SIB1 of the NES cell and then determine whether the NES cell meets the reselection conditions; or, the UE may first determine that the NES cell meets the reselection conditions and then send UL-WUS to request the OD-SIB1 of the NES cell.

[0337] As shown in Figure 4, the specific process of Embodiment 1 may include some or all of the steps in S1-1 to S1-7.

[0338] S1-1. The UE is camped on cell A. The second WUS configuration is broadcast in SIB X of cell A. The second WUS configuration is used to configure the UE to request OD-SIB1 of NES cell in cell A.

[0339] S1-2. When the uplink wake-up signal (UL-WUS) triggering condition is met (e.g., the NES cell meets the R criterion and has the highest R value among multiple candidate cells, so it sends WUS), the UE sends UL-WUS 1 in cell A based on the second WUS configuration to request the NES cell's OD-SIB1.

[0340] S1-3.cell A responds to the UE's UL-WUS1 and sends WUS feedback;

[0341] S1-4. The UE receives WUS feedback in cell A and receives OD-SIB1 of the NES cell, and determines whether the NES cell allows camping. If the NES cell meets the camping conditions, the UE camps in the NES cell. Optionally, the OD-SIB1 of the NES cell may include a first WUS configuration, which is used to configure the UE to request the OD-SIB1 of the NES cell in the NES cell.

[0342] S1-5. Before the OD-SIB 1 of the NES cell expires, the UE sends a UL-WUS2 request for the OD-SIB 1 of the NES cell based on the first WUS configuration.

[0343] S1-6.NES cell responds to UL-WUS2 and sends WUS feedback;

[0344] S1-7. The UE receives the OD-SIB 1 from the NES cell.

[0345] Optionally, in embodiment 1, the UE can simultaneously obtain a first WUS configuration and a second WUS configuration based on SIB X of cell A. The second WUS configuration is used to configure the UE to request OD-SIB 1 of the NES cell in cell A, and the first WUS configuration is used to configure the UE to request OD-SIB 1 of the NES cell in the NES cell.

[0346] Optionally, in Embodiment 1, the UE sends WUS after satisfying the NES cell reselection condition, or determines that the NES cell reselection condition is satisfied only after sending WUS.

[0347] Optionally, in Embodiment 1, the time point at which the UE is allowed to transmit UL-WUS2 includes at least one of the following:

[0348] If OD-SIB 1 expires within X h / min / s, the terminal will send UL-WUS2;

[0349] When the terminal obtains the valid OD-SIB 1 of the NES cell, it sends UL-WUS2 at Y h / min / s / frame / sub-frame.

[0350] The terminal sends UL-WUS2 when it has been residing in the NES cell for Z h / min / s / frame / sub-frame.

[0351] When the terminal obtains a valid OD-SIB 1, it starts timer 1 (e.g., 2 hours). After timer 1 expires, the UE can send UL-WUS2.

[0352] When the terminal obtains a valid OD-SIB 1, it starts timer 2. After timer 2 runs to a threshold (e.g., 2 hours), the terminal can send UL-WUS2.

[0353] Before the terminal obtains a valid OD-SIB 1 timeout of X h / min / s / frame / sub-frame, it starts timer 3. During the operation of timer 3, UL-WUS2 can be sent.

[0354] Example 2 uses an example where the first cell is an NES cell, the second cell is cell A, and the SIB of the first cell is OD-SIB 1. In Example 2, the terminal (UE) camps on cell A. When the cell reselection condition is met, the UE sends UL-WUS1 in cell A to obtain the OD-SIB 1 of the NES cell. Cell A wakes up the NES cell via the Xn message. After being woken up, the NES cell is in a normal state of sending OD-SIB 1 (e.g., the NES cell periodically sends OD-SIB 1). The UE reselects to the NES cell and camps on it. When a UE requests the OD-SIB 1 of the NES cell, cell A wakes up the NES cell via the Xn interface. This addresses the issue of ensuring the validity of the SIB and the WUS configuration after the UE camps on the NES cell.

[0355] As shown in Figure 5, the specific process of Embodiment 2 may include some or all of the steps in S2-1 to S2-5.

[0356] S2-1. The UE is camped on cell A. The second WUS configuration is broadcast in SIB X of cell A. The second WUS configuration is used to configure the UE to request OD-SIB 1 of NES cell in cell A.

[0357] S2-2. When the uplink wake-up signal (UL-WUS) trigger condition is met, the UE sends UL-WUS1 in cell A based on the second WUS configuration to request OD-SIB 1 of the NES cell;

[0358] S2-3.cell A responds to the UE's UL-WUS1 and sends WUS feedback;

[0359] S2-4. The UE receives OD-SIB 1 from the NES cell in cell A and determines whether the NES cell allows camping. If the NES cell meets the camping conditions, the UE camps in the NES cell.

[0360] S2-5. Cell A wakes up the NES cell via the Xn interface, and the NES cell begins to send OD-SIB 1 normally (e.g., the NES cell sends OD-SIB 1 periodically).

[0361] Optionally, in embodiment 2, the NES cell does not continuously listen to UL-WUS; the NES cell only starts listening to UL-WUS when cell A wakes up the NES cell through the Xn interface.

[0362] Optionally, in Example 2, the conditions for cell A to wake up the target NES cell include:

[0363] A terminal requests OD-SIB 1 from the NES cell;

[0364] The number of terminals requesting OD-SIB 1 of the NES cell is greater than or equal to the threshold 1;

[0365] A terminal requests WUS configuration for the NES cell;

[0366] The number of terminals requesting OD-SIB 1 of the NES cell is greater than or equal to threshold 2;

[0367] A terminal obtained the WUS configuration requesting the NES cell.

[0368] Example 3 uses an example where the first cell is an NES cell, the second cell is cell A, and the SIB of the first cell is OD-SIB 1. In Example 3, the terminal (UE) camps on cell A. The UE sends UL-WUS1 in cell A to obtain the OD-SIB 1 of the NES cell (e.g., the validity period of the NES cell's SIB 1 is 3 hours). When the NES cell meets the cell reselection conditions, the UE performs reselection, reselects to the NES cell, and camps on the NES cell. The NES cell sends a short message (e.g., a system message modification indication) every 3 hours or less (e.g., 2 hours) to update the system message and sends OD-SIB 1 for a period of time (the purpose of the short message is to indicate to the UE that the NES cell will send OD-SIB 1 for a period of time later). This solves the problem of the OD-SIB 1 obtained from cell A expiring after the UE camps on the NES cell.

[0369] As shown in Figure 6, the specific process of Embodiment 3 may include some or all of the steps in S3-1 to S3-6.

[0370] S3-1. The UE is camped on cell A. The second WUS configuration is broadcast in SIB X of cell A. The second WUS configuration is used to configure the UE to request OD-SIB 1 of NES cell in cell A.

[0371] S3-2. When the UL-WUS triggering condition is met, the UE sends UL-WUS1 in cell A based on the second WUS configuration to request OD-SIB 1 of the NES cell;

[0372] S3-3.cell A responds to the UE's UL-WUS1 and sends WUS feedback;

[0373] S3-4. The UE receives OD-SIB 1 from the NES cell in cell A and determines whether the NES cell allows camping. If the NES cell meets the camping conditions, the UE camps in the NES cell.

[0374] S3-5. The NES cell initiates an SI update procedure (such as sending a short message) for the UEs residing in the NES cell every 3 hours or less. This short message is used to instruct the UE to send OD-SIB 1 or to notify the system of message changes; the sending of OD-SIB 1 can also be instructed through a paging message.

[0375] S3-6. The UE receives a short message and begins receiving OD-SIB 1 at the start of the next modification period.

[0376] Optionally, in Embodiment 3, if the UE receives a short message, the UE's behavior includes:

[0377] The UE only receives OD-SIB 1 within a timer (such as the fourth timer); or,

[0378] The UE immediately begins receiving or acquiring OD-SIB 1; or,

[0379] The UE will begin receiving or acquiring OD-SIB 1 in the next time window or period.

[0380] Optionally, the time window or period may include: a modification period, or a SIB 1 period.

[0381] Optionally, in Embodiment 3, if the UE receives a short message, the UE's behavior in receiving OD-SIB 1 includes:

[0382] The UE assumes that the network-side OD-SIB 1 only sends n cycles (the cycle includes the modification period and the SIB1 cycle), that is, the UE only listens to n cycles of OD-SIB 1.

[0383] The UE assumes that the network side continuously sends OD-SIB 1;

[0384] The UE assumes that the network side only sends OD-SIB 1 during the operation of a timer (such as the fourth timer).

[0385] Optionally, in Embodiment 3, when the UE receives P-RNTI scrambled DCI 1_0 in the first cell, a timer (such as a fourth timer) is started, and during the operation of the timer (such as the fourth timer), the UE receives OD-SIB 1.

[0386] Example 4 uses an example where the first cell is an NES cell, the second cell is cell A, the SIB of the first cell is OD-SIB 1, and the target message is DCI. In Example 4, the NES cell can use a DCI scrambled by P-RNTI to indicate the transmission of OD-SIB 1 of the NES cell.

[0387] In related technologies, the DCI carries a Short Messages Indicator and Short Messages. As shown in Table 3, the short message is an 8-bit bitmap. If the first bit is set to 1, it means that the UE needs to read SIB 1 for SIBs other than SIB 6, SIB 7, and SIB 8. The UE determines whether it is necessary to reread each SIB based on the version number (value tag) in SIB 1.

[0388] Table 3

[0389] In Example 4, after the UE camps on the NES cell (without sending SIB 1), in order to ensure the validity of the OD-SIB 1 obtained by the UE, the network side can instruct the OD-SIB 1 to start sending via a short message. As shown in Table 4, the eight bits of the short message can be fully utilized to indicate the content related to the sending of OD-SIB 1.

[0390] Table 4

[0391] Among them, the 5th to 8th digits can be combined with the 1st to 4th digits to represent different meanings. The 5th to 8th digits can be used to indicate:

[0392] The OD-SIB 1 transmission duration (value, in microseconds / ms / s / min) of the NES cell, for example, bits 5-8 (4 bits in total, b5, b6, b7, b8) indicate that the OD-SIB 1 transmission will last from 1 to 16 ms / s / min; or,

[0393] The transmission cycle of OD-SIB 1 in the NES cell, for example, uses bits 5-7 (3 bits in total, b5, b6, b7) to indicate that OD-SIB 1 will transmit for 1-8 cycles; or,

[0394] The number of times OD-SIB 1 is transmitted in the NES cell, for example, bits 5-7 (3 bits in total, b5, b6, b7) indicate that OD-SIB 1 will be transmitted 1-8 times; or,

[0395] Whether the OD-SIB 1 of the NES cell is continuously transmitted, for example, the 5th bit (b5) is used to indicate whether the OD-SIB 1 will continue to be transmitted.

[0396] Optionally, in embodiment 4, if bits 5-8 are used to indicate the transmission duration of OD-SIB 1 of the NES cell, when the short message received by the UE indicates that the first bit is set to 1, and the value indicated by bits 5-8 (b5,b6,b7,b8) is L1, then the UE assumes that the transmission duration of OD-SIB 1 of the NES cell is L1 microseconds / ms / s / min.

[0397] Optionally, in Embodiment 4, the last four bits (b5, b6, b7, b8) of the short message can be used in combination with the first four bits (b1, b2, b3, b4). For example, when b1 = 1 and b5, b6, b7, b8 are not zero or not all zero, the UE determines the network side's behavior of sending OD-SIB 1 based on b5, b6, b7, b8; or, when b2 = 1 and b5, b6, b7, b8 are not zero or not all zero, the UE determines the network side's behavior of sending OD-SIB 1 based on b5, b6, b7, b8. In short, when one or more bits of b1, b2, b3, b4 are specific values ​​(1 or 0), and b5, b6, b7, b8 are not zero, the UE can determine the network side's behavior of sending OD-SIB 1 or the duration of sending OD-SIB 1 based on b5, b6, b7, b8.

[0398] Optionally, in embodiment 4, if bits 5-8 are used to indicate the number of OD-SIB 1 transmission cycles of the NES cell, when the short message received by the UE indicates that the first bit is set to 1, and the value indicated by bits 5-8 (b5,b6,b7,b8) is L2, then the UE assumes that the OD-SIB 1 of the NES cell has transmitted L2 cycles.

[0399] Optionally, in embodiment 4, if bits 5-8 are used to indicate the number of times OD-SIB 1 is sent by the NES cell, when the short message received by the UE indicates that the first bit is set to 1, and the value indicated by bits 5-8 (b5,b6,b7,b8) is L3, then the UE assumes that OD-SIB 1 of the NES cell has been sent L3 times.

[0400] Optionally, in embodiment 4, if the 5th bit is used to indicate whether the OD-SIB 1 of the NES cell will continue to be transmitted, when the short message received by the UE indicates that the first bit is set to 1 and the value indicated by the 5th bit (b5) is 1, the UE assumes that the OD-SIB 1 of the NES cell has started to be transmitted normally.

[0401] Optionally, in embodiment 4, when the UE receives P-RNTI scrambled DCI 1_0 in the NES cell, and one or more bits of the first four bits (b1, b2, b3, b4) of the short message are specific values ​​(1 or 0), and the last four bits (b5, b6, b7, b8) of the short message are not zero, a timer (such as a fourth timer) is started. During the operation of the timer (such as the fourth timer), the UE receives OD-SIB 1 from the NES cell.

[0402] Optionally, in embodiment 4, when the UE receives P-RNTI scrambled DCI 1_0 in the NES cell, and the last four bits (b5, b6, b7, b8) of the short message are not zero, the last four bits can be used to indicate whether OD-SIB1 is sent periodically, the number of sending cycles, the number of sending, the duration of the fourth timer, and other information. The UE receives OD-SIB 1 from the NES cell based on this DCI 1_0.

[0403] Example 5 uses an NES cell as the first cell, cell A as the second cell, and OD-SIB 1 as the SIB of the first cell. In Example 5, when the UE is camped on cell A, the network side is configured with both a first WUS configuration that can request OD-SIB 1 from cell A and a second WUS configuration that can request OD-SIB 1 from the NES cell. When the UL-WUS triggering condition is met, the UE selects either the first WUS configuration or the second WUS configuration.

[0404] Optionally, in Embodiment 5, the UE can choose to send UL-WUS based on the first WUS configuration or the second WUS configuration, according to the default / pre-agreed rules.

[0405] The default / pre-agreed rules include:

[0406] UL-WUS is sent preferentially based on the first WUS configuration;

[0407] Prioritize sending UL-WUS based on the second WUS configuration;

[0408] If the number of failed UL-WUS transmissions based on the first WUS configuration exceeds a threshold, then the UE will transmit UL-WUS based on the second WUS configuration.

[0409] If the number of failed UL-WUS transmissions based on the second WUS configuration exceeds a threshold, the UE will transmit UL-WUS based on the first WUS configuration.

[0410] Optionally, in Embodiment 5, the UE can select either a first WUS configuration or a second WUS configuration based on network-side instructions. For example, the network side may instruct the UE that the cell only supports transmitting UL-WUS based on the first WUS configuration or that the cell only supports transmitting UL-WUS based on the second WUS configuration.

[0411] Optionally, in embodiment 5, the UE can select to send UL-WUS based on the first WUS configuration or the second WUS configuration, according to the reference signal measurement results of cell A.

[0412] For example, if the reference signal measurement result is in interval 1, the UE sends UL-WUS based on the second WUS configuration.

[0413] For example, if the reference signal measurement result (including RSRP / SINR) is greater than the threshold value, UL-WUS can be sent based on either the first WUS configuration or the second WUS configuration.

[0414] For example, if the reference signal measurement result (including RSRP / SINR) is less than the threshold value, UL-WUS can be sent based on either the first WUS configuration or the second WUS configuration.

[0415] Optionally, in Embodiment 5, the UE can select to send UL-WUS based on the first WUS configuration or the second WUS configuration, according to the reference signal measurement results of the NES cell.

[0416] For example, if the reference signal measurement result is in interval 2, the UE sends UL-WUS based on the first WUS configuration.

[0417] For example, if the reference signal measurement result (including RSRP / SINR) is greater than the threshold value, UL-WUS can be sent based on either the first WUS configuration or the second WUS configuration.

[0418] For example, if the reference signal measurement result (including RSRP / SINR) is less than the threshold value, UL-WUS can be sent based on either the first WUS configuration or the second WUS configuration.

[0419] Example 6 uses an NES cell as the first cell, cell A as the second cell, OD-SIB 1 as the SIB of the first cell, and DCI format 1_0 as the target message. In Example 6, the Short Message indicator in DCI format 1_0 is used to indicate the transmission of OD-SIB 1 of the NES cell.

[0420] In related technologies, the P-RNTI scrambled DCI format 1_0 carries a Short Messages Indicator and Short Messages. The Short Messages Indicator indicates whether the content in the DCI includes paging scheduling information and whether it contains short messages. When the Short Messages Indicator is set to '00', it is a reserved bit and has no meaning.

[0421] Optionally, in Embodiment 6, when the UE detects that the Short Messages Indicator in the DCI format 1_0 scrambled by P-RNTI is set to '00', the UE assumes that the NES cell has started / normally transmits OD-SIB 1. If the Short Messages Indicator is a specific value, the UE assumes that the NES cell is in a state of normal transmission of OD-SIB 1, as shown in Table 5.

[0422] Table 5

[0423] Optionally, in embodiment 6, when the UE receives P-RNTI scrambled DCI format 1_0 in the NES cell and the Short Messages Indicator is a specific value, a timer (such as a fourth timer) is started. During the operation of the timer (such as the fourth timer), the UE receives OD-SIB 1 from the NES cell.

[0424] Example 7 uses an example where the first cell is an NES cell, the second cell is cell A, the SIB of the first cell is OD-SIB 1, and the target message is DCI format 1_0. In Example 7, the short message and short message indicator in DCI format 1_0 jointly indicate the transmission of OD-SIB 1 of the NES cell.

[0425] Optionally, in embodiment 7, when the Short Messages Indicator is a specific value (e.g., Short Messages Indicator is set to '00') and the last four bits (b5, b6, b7, b8) of the short message are not zero or not all zero, it is used to indicate the transmission of OD-SIB 1 of the NES cell.

[0426] Optionally, in embodiment 7, when the UE receives P-RNTI scrambled DCI format 1_0 in the first cell, when the Short Messages Indicator is a specific value (e.g., the Short Messages Indicator is set to '00') and the last four bits (b5, b6, b7, b8) of the short message are not zero or not all zero, a timer (e.g., a fourth timer) is started. During the operation of the timer (e.g., the fourth timer), the UE receives OD-SIB 1 from the NES cell.

[0427] Example 8 uses an example where the first cell is an NES cell, the second cell is cell A, and the SIB of the first cell is OD-SIB 1. The specific process of Example 8 may include some or all of the steps in S8-1 to S8-6.

[0428] S8-1. The UE is camped on cell A. The second WUS configuration is broadcast in SIB X of cell A. The second WUS configuration is used to configure the UE to request OD-SIB 1 of NES cell in cell A (e.g., the validity period of SIB 1 of NES cell is 3 hours).

[0429] S8-2. When the UL-WUS triggering condition is met, the UE sends UL-WUS1 in cell A based on the second WUS configuration to request OD-SIB1 of the NES cell; and the WUS configuration includes the duration of a timer (such as a fourth timer);

[0430] S8-3.cell A responds to the UE's UL-WUS1 and sends WUS feedback;

[0431] S8-4. The UE receives OD-SIB 1 from the NES cell in cell A and determines whether the NES cell allows camping. If the NES cell meets the camping conditions, the UE camps in the NES cell.

[0432] S8-5. The NES cell initiates an SI update procedure (sends a short message) for the UEs camped on the NES cell every 3 hours or less. This short message is used to indicate the transmission of OD-SIB 1 by the NES cell.

[0433] S8-6. The UE receives a short message and starts a timer (such as the fourth timer) in the next time unit / modification period after receiving the short message. During the operation of the timer (such as the fourth timer), the UE receives OD-SIB 1 from the NES cell. The duration of the timer (such as the fourth timer) is carried by the WUS configuration.

[0434] Example 9 uses an example where the first cell is an NES cell, the second cell is cell A, and the SIB of the first cell is OD-SIB 1. In Example 9, after the UE camps on the NES cell, it determines the OD-SIB 1 of the NES cell based on the short message. Specifically, in Example 9, the UE receives WUS configuration in cell A, sends WUS (which can actually be understood as the first uplink signal) in the NES cell, receives OD-SIB 1 in the NES cell, camps on the NES cell, receives the short message of the NES cell, and receives the OD-SIB 1 of the NES cell.

[0435] As shown in Figure 7, the specific process of Embodiment 9 may include some or all of the steps in S9-1 to S9-5.

[0436] S9-1. The UE is camped on cell A. The first WUS configuration is broadcast in SIB X of cell A. The first WUS configuration is used to configure the UE to request OD-SIB 1 of the NES cell in the NES cell (e.g., the validity period of SIB 1 of the NES cell is 3 hours).

[0437] S9-2. When the UL-WUS triggering condition is met, the UE sends UL-WUS 1 in the NES cell based on the first WUS configuration to request the NES cell's OD-SIB1;

[0438] S9-3. The UE receives the OD-SIB1 of the NES cell in the NES cell;

[0439] S9-4. After the UE camps on the NES cell, the UE receives short messages in the NES cell. The short message can carry WUS configuration, or the OD-SIB 1 of the NES cell can carry WUS configuration. The WUS configuration can carry the reception configuration of the OD-SIB 1 of the NES cell, including SS 0, CORESET0 configuration, OD-SIB 1 transmission period, OD-SIB 1 transmission count, OD-SIB 1 transmission duration, OD-SIB 1 feedback reception configuration, and WUS feedback listening configuration.

[0440] S9-5. The UE receives the OD-SIB1 of the NES cell based on the short message in the NES cell.

[0441] Example 10 uses an NES cell as the first cell, cell A as the second cell, and OD-SIB 1 as the SIB of the first cell. In Example 10, the UE camps on the NES cell and assumes that the NES cell periodically transmits OD-SIB 1. Specifically, in Example 10, the UE receives WUS configuration in cell A, transmits WUS (which can actually be understood as the first uplink signal) in the NES cell, receives OD-SIB 1 in the NES cell, and camps on the NES cell, assuming that the NES cell periodically transmits OD-SIB 1.

[0442] As shown in Figure 8, the specific process of Embodiment 10 may include some or all of the steps in S10-1 to S10-4.

[0443] S10-1. The UE camps on cell A, and the first WUS configuration is broadcast in SIB X of cell A. The first WUS configuration is used to configure the UE to request OD-SIB 1 of the NES cell in the NES cell (e.g., the validity period of SIB 1 of the NES cell is 3 hours).

[0444] S10-2. When the UL-WUS triggering condition is met, the UE sends UL-WUS 1 in the NES cell based on the first WUS configuration to request the NES cell's OD-SIB1;

[0445] S10-3. The UE receives the OD-SIB1 of the NES cell in the NES cell;

[0446] S10-4. The UE camps on the NES cell. Assume that the NES cell periodically sends OD-SIB 1, and the UE periodically receives OD-SIB1 from the NES cell in the NES cell.

[0447] Example 11 uses an NES cell as the first cell, cell A as the second cell, and OD-SIB 1 as the SIB of the first cell. In Example 11, the UE camps on the NES cell. Before the OD-SIB 1 of the NES cell expires, the UE sends a WUS request for the OD-SIB 1 of the NES cell again. Specifically, in Example 11, the UE receives the WUS configuration in cell A, sends WUS1 in the NES cell, receives OD-SIB1 in the NES cell (e.g., the validity period of SIB 1 of the NES cell is 3 hours), camps on the NES cell, and before SIB1 expires, the UE sends WUS2 based on the WUS configuration contained in the OD-SIB 1 obtained in the NES cell, requesting the OD-SIB 1 of the NES cell again.

[0448] As shown in Figure 9, the specific process of Embodiment 11 may include some or all of the steps in S11-1 to S11-6.

[0449] S11-1. The UE is camped on cell A. The first WUS configuration is broadcast in SIB X of cell A. The first WUS configuration is used to configure the UE to request OD-SIB 1 of the NES cell in the NES cell.

[0450] S11-2. When the UL-WUS triggering condition is met, the UE sends UL-WUS 1 in the NES cell based on the first WUS configuration to request the NES cell's OD-SIB1;

[0451] S11-3. The UE receives the OD-SIB1 of the NES cell in the NES cell;

[0452] S11-4. After the UE camps on the NES cell, the UE sends UL-WUS2 based on the WUS configuration included in the OD-SIB1 of the NES cell to request the OD-SIB1 of the NES cell.

[0453] S11-5. The UE receives WUS feedback from the NES cell;

[0454] S11-6. The UE receives OD-SIB1 from the NES cell in the NES cell.

[0455] Example 12 uses an example where the first cell is an NES cell, the second cell is cell A, and the SIB of the first cell is OD-SIB 1. In Example 12, the UE camps on the NES cell. The OD-SIB1 of the NES cell is about to expire. The UE attempts to decode the OD-SIB1 of the NES cell but finds that it cannot receive the OD-SIB1 of the NES cell. The UE believes that the NES cell has been barred and begins the cell selection process.

[0456] In Example 12, WUS configuration is received in cell A, WUS is sent in NES cell (this WUS can actually be understood as the first uplink signal), OD-SIB 1 is received in NES cell, and the UE camps in NES cell. Before OD-SIB 1 expires, the UE attempts to decode OD-SIB 1, but does not receive OD-SIB 1 from NES cell. The UE believes that NES cell has been barred and starts the cell selection process.

[0457] Alternatively, in embodiment 12, WUS configuration is received in cell A, WUS is sent in NES cell (this WUS can actually be understood as the first uplink signal), OD-SIB 1 is received in NES cell, and the UE camps in NES cell. Before OD-SIB 1 expires, the UE attempts to decode OD-SIB 1, but does not receive OD-SIB 1 from NES cell. The UE believes that NES cell has been barred and directly reselects back to cell A.

[0458] Example 13 uses an example where the first cell is an NES cell, the second cell is cell A, and the SIB of the first cell is OD-SIB 1. In Example 13, the UE sends UL-WUS, receives WUS feedback, starts a timer (such as a first timer), and receives OD-SIB 1 from the NES cell during the operation of the first timer.

[0459] In Example 13, if the NES cell continues to periodically send OD-SIB 1 after the UE sends WUS, it will be detrimental to subsequent network energy saving. Therefore, a mechanism can be designed so that the UE receives OD-SIB 1 for a period of time after sending WUS, and after this period, the UE assumes that the NES cell has stopped sending OD-SIB 1.

[0460] Optionally, in embodiment 13, the UE receives WUS configuration in cell A, sends WUS in NES cell, listens for WUS feedback, and after receiving WUS feedback, starts a first timer and receives OD-SIB 1 from NES cell during the operation of the first timer.

[0461] Optionally, in embodiment 13, WUS configuration is received in cell A, WUS is transmitted in cell A, the UE listens for WUS feedback, and after receiving WUS feedback, a first timer is started, during which the OD-SIB 1 of the NES cell is received.

[0462] It should be noted that "after receiving WUS feedback" can be understood or described as the received Random Access Response (RAR) containing the same preamble identifier as the uplink request signal, or as receiving an on-demand signal request for acknowledgment, or as receiving acknowledgement for on-demand SIB1 request.

[0463] It should be noted that "WUS feedback" is equivalent to WUS response, equivalent to RAR, equivalent to on-demand request signal response, equivalent to on-demand request signal feedback, equivalent to on-demand request signal acknowledgment, and equivalent to the response of the first uplink signal or the response of the second uplink signal involved in the embodiments of this application.

[0469] Y time units after receiving the WUS feedback, the time unit containing the first SSB sent by the NES cell is received;

[0470] After receiving the WUS feedback for Z time units, the time unit containing the first SIB sent by the NES cell is received;

[0471] Upon receiving feedback from WUS, a second timer is started. After the second timer expires, the first timer is started. The second timer is used to ensure the time for the UE to decode RAR.

[0472] Optionally, the length / duration of the first timer can be configured by the network side or agreed upon in advance by the protocol, or the length / duration of the first timer can be carried by the WUS configuration, or the length / duration of the first timer can be carried by the WUS response, or the length / duration of the first timer can be carried by the paging message, or the length / duration of the first timer can be carried by the short message.

[0479] The indication methods include directly indicating a specific value, or indicating the identifier corresponding to the value;

[0480] For example, if the network side is configured with 10 values, numbered 0-9, the WUS configuration indicates that the specific number corresponds to the duration of a certain timer.

[0481] Optionally, in embodiment 13, the duration of the first timer is configured in the WUS configuration and associated with the cell ID of a certain NES cell. After the UE sends UL-WUS, it receives WUS feedback and starts the first timer on the next Type 0PDCCH occasion. The duration of the first timer is configured by WUS. The UE receives the OD-SIB 1 of the NES cell within the first timer. After the first timer expires, the UE assumes that the network side stops sending the OD-SIB 1 of the NES cell.

[0482] Optionally, in embodiment 13, the UE's behavior within the first timer includes listening to the Type 0PDCCH on a Type 0PDCCH occasion, the Type 0PDCCH being used to receive OD-SIB 1 from the NES cell.

[0515] Optionally, the location of the WUS response monitoring occupancy (MO) is determined relative to the WUS. Optionally, some domains can be set to invalid, such as the frequency domain resource assignment (FDRA), which can be invalid to indicate that this is a UL WUS response.

[0516] Example 14 uses an NES cell as the first cell, cell A as the second cell, and OD-SIB 1 as the SIB of the first cell. In Example 14, the short message in the DCI of the NES cell carries the WUS configuration, which includes SS0 and CORESET0 configurations.

[0523] Example 15 uses an NES cell as the first cell, cell A as the second cell, and OD-SIB 1 as the SIB of the first cell. In Example 15, the OD-SIB1 of the NES cell carries the WUS configuration, which includes CORESET0 and SS0 configurations.

[0524] Optionally, in embodiment 15, the OD-SIB 1 of the NES cell indicated by the Short message carries the WUS configuration:

This is done if the NES cell's OD-SIB 1 carries the WUS configuration, and the WUS configuration includes the NES cell's OD-SIB 1 receive configuration, including SS0, CORESET0 configuration, SIB1 transmission period / number, transmission timer duration, feedback receive configuration, and WUS feedback listening configuration.

[0528] Optionally, in Example 15, the UE assumes that after transmitting WUS, the NES cell periodically transmits OD-SIB 1:
