[0023] This disclosure provides a communication method, communication device, communication system, and storage medium.
[0024] In a first aspect, embodiments of this disclosure propose a communication method executed by a network device, comprising: sending first information, wherein the first information is used to indicate that the SI window and the cell DTX activation period overlap in time; the SI window is a time window in which the network device sends system messages.
[0025] In the above embodiments, the network device can indicate that the SI window overlaps (or matches) with the cell DTX activation period in time, that is, the SI window can at least partially fall within the cell DTX activation period, thereby increasing the probability that the terminal can listen to system messages. Furthermore, the network device in this embodiment operates in a discontinuous transmission scenario, thus also achieving energy saving, i.e., saving energy consumption of the terminal and network device. In other words, this embodiment can increase the probability that the terminal can listen to system messages while saving energy in the communication system.
[0026] In conjunction with some embodiments of the first aspect, in some embodiments, the SI window and the cell DTX activation period overlap in time, including at least one of the following: the period of the SI window is an integer multiple of the period of the cell DTX; the default paging period is an integer multiple of the period of the cell DTX; all or part of the SI window is located within the activation period of the cell DTX.
[0027] In the above embodiments, the SI window and the cell DTX activation period can overlap in time through various methods, so that the SI window can fall within the cell DTX activation period.
[0028] In conjunction with some embodiments of the first aspect, in some embodiments, the method further includes: sending second information; wherein the second information is used to indicate whether a system message is sent within a first time period, the first time period including at least one of the following: each cell DTX activation period after the time of sending the second information; the cell DTX activation period in which the time of sending the second information is located; the Nth cell DTX activation period after the time of sending the second information, where N is a positive integer; the Mth cell DTX activation period after the time of sending the second information, where M is an integer greater than 1.
[0029] In the above embodiments, the system message can be sent during the DTX activation period of a cell by network instruction. This allows the terminal to listen for system messages during the corresponding DTX activation period, thereby enabling the terminal to effectively listen while saving energy and increasing the probability of the terminal listening for system messages.

[0031] In the above embodiments, the first system message with higher priority can be sent not only during the cell DTX active period, but also during the cell DTX inactive period. That is, the time limit for sending high-priority system messages can be relaxed, so as to further improve the success rate of the terminal listening to the first system message with relatively higher priority.
[0032] In conjunction with some embodiments of the first aspect, in some embodiments, the second information is sent via at least one of the following: System Information Block 1 (SIB1), Random Access Response (RAR), or Layer 1 signaling.

[0101] (1) Determine the start time of the SI window for the relevant SI message, as shown below:
[0102] If relevant SI messages are configured in the schedulingInfoList:
[0103] For the relevant SI message, determine the number n that corresponds to the order of the entries in the SI message list configured in the SI scheduling information list in SIB1;
[0104] Determine the integer value x = (n-1) × w, where w is the length of the SI window;
[0105] The SI window starts from time slot #a, where a = x mod N, and in the radio frame SFN mod T = floor(x / N); where T is the SI period of the relevant SI message, and N is the number of time slots in the radio frame.
[0106] (2) Receive the Physical Downlink Control Channel (PDCCH) including the Radio Network Temporary Identifier (RNTI), i.e., the SI-RNTN that obtains the PDCCH monitoring timing from the SI message. The absolute length of the SI window is determined by the SI window length, or until the SI message is received.
[0107] (3) If no SI message is received at the end of the SI window, the relevant SI message in the current modification period will be received again at the next SI window.
[0108] That is, for the nth SI message, the network first finds its starting point window, i.e., x. Then, it finds the starting position of the SI window (SI-window) according to the period.
[0109] The terminal decodes system messages in the SI window until it parses the system message. If decoding fails in the current SI window, it can continue listening in the next SI window of the current modification cycle.
[0110] In some embodiments, the need for network energy saving:
[0111] In communication technology, cell-level Discontinuous Reception (DRX) reduces the frequency of data transmission and reception on the network side by configuring DTX / DRX patterns, thereby achieving energy savings on the network side. During the non-active period of cell DTX / DRX, the network side does not need to transmit or receive certain channels (signals). For example, it does not need to transmit the PDCCH. Correspondingly, the terminal also does not need to blindly detect the PDCCH, thus achieving energy savings on both the network and terminal sides.
[0112] However, during cell DTX non-active periods, to ensure the synchronization / beam performance of the terminals while minimizing the impact on non-connected terminals, the base station continues to transmit Channel State Information-Reference Sign (CSI-RS) for beam measurement, Tracking Reference Signal (TRS) or Synchronization Signal Block (SSB) for synchronization, and common signals for non-connected terminals, such as SSB, paging signals, SIB1, and Physical Random Access Channel (PRACH). Figure 1B As shown: the base station transmits downlink (DL) signals during the active period of cell DTX (C-DTX) and does not transmit DL signals during the inactive period of C-DTX; the base station receives UL signals during the active period of cell DRX (C-DRX) and does not receive UL signals during the inactive period of C-DRX.
[0113] In some embodiments, the current system message sending mechanism has the following problems:
[0114] (1) For the current SIB, the SI window is configured by the network (NW) and will not change dynamically.
[0115] (2) The UE will monitor the SIB based on the SI window. It is very likely that the SI window is not within the cell DTX active period, so the UE will not be able to decode the SI window, resulting in more power consumption.
[0116] (3) Even if NW can try to configure SI windows during the cell DTX activation period, it is still difficult to accommodate all SI windows if the cell DTX activation period is short.
[0117] (4) At the same time, Lay1 will dynamically change the cell DTX mode, making it difficult to find all active time slots of all SI windows.
[0118] Therefore, a more dynamic SI window should be considered in communication systems (such as 6G).
[0119] In some embodiments, the UE can be a terminal, or the terminal can be a UE. The Cell DTX activation period can be replaced with the Cell DTX activation time; the Cell DTX inactive period can be replaced with the Cell DTX inactive time.

[0138] In some embodiments, the determination or judgment can be made by a value represented by 1 bit (0 or 1), or by a true or false value (boolean), or by a comparison of numerical values (e.g., a comparison with a predetermined value), but is not limited thereto.
[0139] In step S2102, the network device sends the second information to the terminal.
[0140] In some embodiments, the terminal receives second information sent by the network device.
[0141] Optionally, the second information is used to indicate whether the system message is sent within the first time period. For example, the second information may indicate that the system message is sent within the first time period, or it may indicate that the system message is not sent within the first time period.

[0143] Optionally, the cell DTX activation period can be replaced with the cell DTX activation time; the cell DTX inactive period can be replaced with the cell DTX inactive time.
[0144] Optionally, the name of the second information is not limited, and it may be, for example, a system message sending method or a second indication information.

Optionally, the first system message includes: a system message carrying emergency data.

[0150] Optionally, the second information is used to indicate at least one of the following: whether the system sends the message during the cell DTX activation period, and the time point during the cell DTX activation period.
[0151] Optionally, the second information indicates that the first system message is sent during the cell DTX inactive period. This allows the terminal to listen for important system messages without being restricted by the cell DTX / DRX active period, reducing cell access latency. For less important system messages, the network can send them during the cell DTX / DRX active period at an appropriate time, thus reducing network power consumption.
[0152] In some embodiments, the second information is sent via at least one of the following: System Message Block (SIB1), Random Access Response (RAR), or Layer 1 signaling. Optionally, the second information may also be sent via other signaling, as long as the transmission requirements between the network device and the terminal are met.
[0153] Optionally, the network device sends SIB1 to the terminal, SIB1 including the second information. Accordingly, the terminal receives SIB1 sent by the network device, SIB1 including the second information.
[0154] Optionally, the network device sends a RAR to the terminal, the RAR including the second information. Accordingly, the terminal receives the RAR sent by the network device, the RAR including the second information.
[0155] Optionally, the network device sends Layer 1 signaling to the terminal, the Layer 1 signaling including the second information. Correspondingly, the terminal receives the Layer 1 signaling sent by the network device, the Layer 1 signaling including the second information. For example, the Layer 1 signaling may be wake-up signaling (or a wake-up signal) or other signaling.
[0156] In some embodiments, the first information and the second information can be sent in the same message, or the first information and the second information can be sent separately through different messages. Here, the message is not limited to SIB1, RAR, or Layer 1 signaling as in the previous embodiments.
[0157] In some optional embodiments, the protocol may specify the content indicated by the second information. Optionally, the terminal or network device may determine, according to the protocol, at least one of the following: whether the system message is sent within a first time period, or whether the first system message is sent within a second time period. Optionally, the protocol may specify at least one of the following: whether the message is sent during the cell DTX activation period, or the time point during the cell DTX activation period.
[0158] In step S2103, the network device sends third information to the terminal.
[0159] In some embodiments, the terminal receives third information sent by the network device.
[0160] Optionally, the third information is used to indicate at least one of the following: the time-domain location of the system message being sent, the offset of the time-domain location of the system message being sent from the cell DTX activation period, and the period of the SI window.
[0161] For example, the third information is used to indicate the time domain location of the system message being sent in the Lth time slot of the DTX active period, where L is any time slot of the DTX active period.
[0162] For example, the offset of the time domain position of the system message transmission from the cell DTX activation period can be: the offset of the time domain position of the system message transmission relative to the start point (e.g., the starting time domain position), the end point (e.g., the ending time domain position), or the center point (e.g., the middle time domain position) of the cell DTX activation period.
[0163] Optionally, the third information is used by the terminal to determine the starting time domain position of the SI window.
[0164] Optionally, the name of the third information is not limited; it may be, for example, the system message sending time domain location or third indication information.
[0165] Optionally, the starting time-domain position of the SI window includes at least one of the following: an absolute time-domain position, or an offset relative to the starting time-domain position of the cell DTX activation period.
[0166] For example, the absolute time domain position can be a time slot position, a subframe position, or a symbol position, etc.
[0167] For example, the starting time domain position of the SI window can be an offset relative to the ending time domain position of the cell DTX activation period or an offset relative to the middle time domain position of the DTX activation period.
[0168] Optionally, the third information is used to indicate the starting point of at least one SI window. For example, the second information is used to indicate the starting point of the SI window of SIB X and the starting point of the window of SIB Y. Here, the starting point can be replaced by the initial temporal location.
[0169] Optionally, the third information is used to indicate the starting index of the SI window corresponding to the system message; for example, the index is "si-WindowPosition". In this way, the terminal determines x, that is, the starting position of the SI-Window, by means of x = (si-WindowPosition-1) × w, where w is the window length scheduled.
[0170] Optionally, the third information is used to indicate the duration for which the system message is scheduled; for example, for several SI window lengths.
[0171] In some embodiments, the third information is sent via at least one of the following: System Message Block (SIB1), Random Access Response (RAR), or Layer 1 signaling. Optionally, the third information may also be sent via other signaling, as long as the transmission requirements between the network device and the terminal are met. Optionally, the Layer 1 signaling may be wake-up signaling (or wake-up signal) or other signaling.
[0172] In some embodiments, at least two of the first, second, and third information can be sent in the same message; or, the first, second, and third information can be sent separately through different messages (e.g., the first information is sent through a first message, the second information through a second message, and the third information through a third message). Here, the message is not limited to SIB1, RAR, or Layer 1 signaling as described in previous embodiments.
[0173] In some optional embodiments, the protocol may specify the content indicated by the third information. Optionally, the terminal or network device may determine at least one of the following according to the protocol: the time domain location of sending the system message, the offset between the time domain location of sending the system message and the cell DTX activation period, and the period of the SI window.
[0174] Step S2104: The network device sends the fourth information to the terminal.
[0175] In some embodiments, the terminal receives fourth information sent by the network device.
[0176] Optionally, the fourth information is used to indicate at least one of the following: the first count, and the first duration. For example, the first count is the number of times the terminal listens to the SI window. For example, the first duration is the duration of the terminal listening to the SI window.
[0177] Optionally, the fourth information includes at least one of the following: the first count, the first duration.
[0178] Optionally, the name of the fourth information is not limited, and it may be, for example, SI window monitoring information, SI window monitoring count, SI window monitoring duration, or fourth indication information.
[0179] Optionally, the name of the first count is not limited, and it can be, for example, the number of times it is monitored.
[0180] Optionally, the name of the first duration is not limited, and it may be, for example, the listening duration.
[0181] Optionally, the first duration is at least one of the following: the system message modification cycle, or an integer multiple of the first cycle. For example, the first cycle is one of the following: the cell DTX cycle, or the default paging cycle.
[0182] Optionally, the first duration does not include at least one of the following times: when the network is in a cell DTX inactive period, or when the network is in a specific DTX active period. For example, the specific DTX active period is the cell DTX active period excluding the SI window. For example, if the first and third cell DTX periods have SI windows, but the second cell DTX period does not, then the second cell DTX period is not included in the first duration calculation. For instance, if the first duration is twice the cell DTX period, then the first duration will continue until the end of the third cell DTX period, not the end of the second cell DTX period.
[0183] Optionally, the first duration can be the entire duration of the listening session. For example, if the current network is in the first moment, the listening session can end in the second moment after the first duration of the first moment.
[0184] In some embodiments, the fourth information is sent via at least one of the following: System Message Block (SIB1), Random Access Response (RAR), or Layer 1 signaling. Optionally, the fourth information may also be sent via other signaling, as long as the transmission requirements between the network device and the terminal are met. Optionally, the Layer 1 signaling may be wake-up signaling (or wake-up signal) or other signaling.
[0185] In some embodiments, at least two of the first, second, third, and fourth information can be sent in the same message; or, the first, second, third, and fourth information can be sent separately through different messages (e.g., the first information is sent through a first message, the second information through a second message, the third information through a third message, and the fourth information through a fourth message). Here, the message is not limited to SIB1, RAR, or Layer 1 signaling as described in the previous embodiments.
[0186] In some alternative embodiments, the protocol may specify the content indicated by the fourth information. Optionally, the terminal or network device may determine at least one of the following according to the protocol: the first count, the first duration.
[0187] In step S2105, the terminal listens for system messages based on the SI window.
[0188] In some embodiments, before listening to system messages, the terminal further includes: determining at least one of the following: the time domain position of sending system messages, the starting time domain position of the SI window, the period of the SI window, the number of times to listen to the SI window, and the duration of listening to the SI window.
[0189] In some embodiments, the terminal determines at least one of the following based on third information: the time domain position of sending system messages, the starting time domain position of the SI window, and the period of the SI window.
[0190] Optionally, the terminal determines the time domain location for sending or receiving system messages based on the time domain location of the system message sent as indicated by the third information.
[0191] Optionally, the terminal determines the starting time-domain position of the SI window based on at least one of the time-domain position of the transmitted system message indicated by the third information and the offset of the time-domain position of the transmitted system message from the cell DTX activation period. For example, the starting time-domain position of the SI window determined by the terminal includes at least one of the following: an absolute time-domain position (e.g., a time slot position) and an offset relative to the starting time-domain position of the cell DTX activation period.
[0192] Optionally, the terminal determines the SI period based on the SI period included in the third information.
[0193] In some embodiments, the terminal determines at least one of the following based on the protocol: the time domain position for sending system messages, the starting time domain position of the SI window, and the period of the SI window.
[0194] Optionally, in the absence of third information or if the terminal does not receive third information, the starting time domain position of the SI window is determined based on the protocol agreement. For example, the terminal may determine the starting time domain position of the first time slot bit of the SI window during the cell DTX activation period based on the protocol agreement.
[0195] In some embodiments, the terminal determines at least one of the following based on fourth information: the number of times the SI window is monitored and the duration of the SI window monitoring.
[0196] Optionally, the terminal determines the number of times it listens to the SI window based on the fourth information indication (the number of times it listens to the SI window is the first time).
[0197] Optionally, the terminal determines the duration of the SI window to be the first duration based on the duration indicated by the fourth information.
[0198] Optionally, the first duration does not include at least one of the following times: when the network is in a cell DTX inactive period, or when the network is in a specific DTX active period. For example, the specific DTX active period is the cell DTX active period excluding the SI window. For example, if the first and third cell DTX periods have SI windows, but the second cell DTX period does not, then the second cell DTX period is not included in the first duration calculation. For instance, if the first duration is twice the cell DTX period, then the first duration will continue until the end of the third cell DTX period, not the end of the second cell DTX period.
[0199] For example, the first duration can be the entire duration of the listening session. For example, if the current network is in the first moment, the listening session can end in the second moment after the first duration of the first moment.
[0200] In some embodiments, the terminal listens for system messages based on the SI window.
[0201] Optionally, the terminal listens for system messages based on at least one of the first, second, third, and fourth information.
[0202] Optionally, the terminal listens for system messages based on at least one of the following: the time domain location of the system message, the offset between the time domain location of the system message and the cell DTX activation period, the period of the SI window, the number of times the SI window is listened to, and the duration of the SI window.
[0203] For example, the terminal determines that it is listening to system messages during the cell DTX activation period because the SI window indicated by the first information overlaps with the cell DTX activation period in time.
[0204] For example, the terminal sends the system message indicated by the second information during each cell DTX activation period after the time the second information is sent, and determines to listen to the system message during each cell DTX activation period after the time the second information is sent; or, the terminal sends the system message indicated by the second information during the cell DTX activation period where the time the second information is sent, and determines to listen to the system message during the Nth cell DTX activation period after the time the second information is sent, where N is a positive integer; or, the terminal sends the system message indicated by the second information during M cell DTX activation periods after the time the second information is sent, and determines to listen to the system message during the Mth cell DTX activation periods after the time the second information is sent, where M is an integer greater than 1.
[0205] For example, the terminal sends a first system message based on the second information indication during the cell DTX inactive period, and determines to listen for the first system message during the DTX inactive period.
[0206] For example, the terminal determines the period for listening to system messages based on the SI window period indicated by the third information.
[0207] For example, the terminal determines the time domain location for listening to system messages based on the time domain location of the system message transmission indicated by the third information. For instance, if the network device transmits system messages in the first time slot of the cell DTX activation period, then the terminal transmits system messages during the cell DTX activation period.
[0208] For example, the terminal determines the time domain position at which it listens for system messages based on the offset between the time domain position of the system message sent indicated by the third information and the cell DTX activation period.
[0209] For example, if the terminal indicates the number of times to listen to the SI window based on the fourth information as the first time (e.g., x times), then the terminal determines that the number of times to listen to the SI window is the first time (e.g., x times). For example, after the terminal fails to listen to the current SI window, it continues to listen to the SI window scheduled by the network device until the maximum number of listening times x is reached or the maximum number of listening times has not been reached but a system message has been successfully listened to, and then the listening to the SI window ends.
[0210] For example, if the duration of the SI window to be monitored by the terminal based on the fourth information is a first duration (e.g., T), then the terminal determines that the duration of the SI window to be monitored is the first duration (T). For example, if the terminal fails to monitor the current SI window, it can continue to monitor the network-scheduled SI window for a period of time T until the end of the T period or a system message is successfully monitored, and then the monitoring of the SI window will end.

[0223] In some embodiments, the method further includes: the network device sending third information to the terminal; wherein the third information is used to indicate at least one of the following: the time domain location of sending system messages; the offset between the time domain location of sending system messages and the cell DTX activation period; the period of the SI window; wherein the third information is used by the terminal to determine the starting time domain location of the SI window.
[0224] In some embodiments, the starting time-domain position of the SI window includes at least one of the following: an absolute time-domain position; or an offset relative to the starting time-domain position of the cell DTX activation period.
[0225] In some embodiments, the method further includes: determining the starting time-domain position of the SI window based on protocol conventions.
[0226] In some embodiments, the method further includes: the network device sending fourth information to the terminal; wherein the fourth information is used to indicate at least one of the following: a first count, the first count being the number of times the terminal listens to the SI window; and a first duration, the first duration being the duration of the terminal listening to the SI window.
[0227] In some embodiments, the first duration is at least one of the following: the system message modification period; an integer multiple of the first period; wherein the first period is one of the following: the cell DTX period, the default paging period.
[0228] In some embodiments, the first duration does not include at least one of the following times: when the network is in a cell DTX inactive period; when the network is in a specific DTX active period; wherein, the specific DTX active period is a cell DTX active period excluding the SI window.
[0229] In some embodiments, the method further includes: the terminal listening for system messages based on the SI window.
[0230] In some embodiments, the steps and their optional implementations in other embodiments described before or after this embodiment, as well as other related parts in the specification, can be referred to, and will not be repeated here.
[0231] In this embodiment of the disclosure, the method of sending and receiving system messages is protected under network energy-saving scenarios where Cell DTX is configured on the network.
[0232] In some embodiments, the network should strive to ensure that the scheduling window of the system message (SI) and the active time of the network's Cell DTX overlap to a certain extent. Here, the scheduling window of the system message (SI) can be the SI window in the previous embodiments; the active time of the Cell DTX can be replaced with the active time of the Cell DTX; and the inactive time of the Cell DTX can be replaced with the inactive time of the Cell DTX.
[0233] Optionally, the network should strive to ensure that the scheduling period of the SI window (SI-Window) is an integer multiple of the network's Cell DTX period. Here, the scheduling period of the SI window can be the SI window period as in the previous embodiments.
[0234] For example, the period of the SI window is an integer multiple of the period of the Cell DTX.
[0235] For example, the period of Cell DTX is an integer multiple of the scheduling period of the SI window.
[0236] Optionally, the network should strive to ensure that the default paging period and the network's Cell DTX period are integer multiples of each other. For example, the default paging period is an integer multiple of the Cell DTX period.
[0237] In some embodiments, the network indication or protocol specifies whether the system message is sent during the Cell DTX activation period or the specific time point during the Cell DTX activation period. For example, specifying which Cell DTX activation period it is sent during.
[0238] Optionally, the network device may indicate that the system message is sent during each Cell DTX activation period.
[0239] Optionally, the network device may indicate that the system message is sent during the current Cell DTX activation period.
[0240] Optionally, the network device instructs the system message to be sent during the next Nth Cell DTX activation period, for example, the network instructs the system message to be sent during the first Cell DTX activation period.
[0241] Optionally, the system message may include at least one of the following: a first system message and a second system message; wherein the first system message includes at least one of the following: MIB, SIB1, and a system message carrying earthquake and / or tsunami warnings; the second system message includes system messages other than those carrying earthquake and / or tsunami warnings.
[0242] Optionally, the sending location of the first system message does not require network indication, but is determined by protocol.
[0243] Optionally, because the first system message is more important, it is not subject to the Cell DTX / DRX activation period. That is, the first system message can be sent regardless of whether Cell DTX is active or inactive.
[0244] In this way, the terminal can listen for important system messages without being restricted by the Cell DTX / DRX activation period. This reduces cell access latency. For less important system messages, the network can send them at an appropriate time during the Cell DTX / DRX activation period, thus reducing network power consumption.
[0245] In some embodiments, in addition to sending the network indication system message during the Cell DTX activation period, it can also simultaneously inform the specific sending location, allowing the terminal to determine the starting point of the SI window. Here, the starting point can be the initial time domain location as described in previous embodiments.
[0246] Optionally, the starting point can be a specific time-domain location (i.e., the absolute time-domain location in the previous embodiments), such as the starting point being specifically located at the position of a time slot. Alternatively, the starting point can be an offset from the starting point of Cell DTX activation, such as the starting point being an offset relative to the starting time-domain location of the cell DTX activation period.
[0247] Optionally, if no specific SI window transmission position is indicated, the specific transmission position within the Cell DTX active period can be obtained by the terminal based on a protocol agreement, such as starting transmission from the first slot.
[0248] Optionally, the network can also indicate the period of the SI window.
[0249] Optionally, a net can specify the starting point of multiple SI windows. For example, a net can specify the starting point of the SI-Window of SIB X and the starting point of the SI-Window of SIB Y.
[0250] Optionally, the network can inform a certain SIB of the starting index of its SI-Window, such as si-WindowPosition. In this case, the terminal determines x, i.e. the starting position of the SI-Window, by using x = (si-WindowPosition-1) × w, where w is the window length scheduled.
[0251] Optionally, the network can inform a SIB of the duration of its SI scheduling, such as the duration of several SI-windows.
[0252] In some embodiments, the information that the network indicates to the terminal mentioned above, such as the system message mentioned above sent during the Cell DTX activation period, can be specifically carried in SIB1, RAR, or Layer 1 (lay1) signaling.
[0253] Optionally, the network indicates via SIB1 that a SIBx window will exist in the current cell DTX active time or the next cell DTX active time.
[0254] Optionally, if the UE reads SIB1 and finds that SIBx is not broadcasting, the UE will request SIBx. The NW will indicate in the RAR that the SIBx window will exit during the current cell DTX active time or the next cell DTX active time.
[0255] Optionally, the wake-up signal is used to indicate the information sent by the system message during the duration of the cell DTX activation period.
[0256] For example, the wake-up signal indicates the transmission location of SIBx.
[0257] For example, the wake-up signal indicates whether aSIBx will be broadcast during the next cell DTX active time.
[0258] For example, the wake-up signal indicates whether there are important system messages sent during a certain Cell DTX activation period, such as the first system message (e.g., earthquake and / or tsunami warning).
[0259] This allows for timely notification of the terminal to listen for important system messages.
[0260] In some embodiments, the terminal listens for system messages at the location of the SI window of the system indicated by the network.
[0261] In some embodiments, the network may instruct the terminal to decode the SI window a number of times and / or a range of durations.
[0262] Optionally, if the network indicates that the SI window has listened for x times, then if listening to SI in the current SI window fails, it can continue to listen in the SI window scheduled by the network until the maximum number of listening times is reached.
[0263] Optionally, if the listening period of the network-indicated SI window is T, then if listening to SI fails in the current SI window, listening can continue in the network-scheduled SI window for a period of T until the end of the period, or until a system message is successfully listened to.
[0264] Optionally, this T listening period can be the system message modification cycle.
[0265] Optionally, the T listening period can be an integer multiple of the first cycle of the network configuration; the first cycle can be: the Cell DTX cycle or the default paging cycle.
[0266] Optionally, when calculating the T listening period, if the network is in an inactive Cell DTX period or an active Cell DTX period but does not include the SI window for system messages (i.e., no scheduled system messages), the period can be skipped from the statistics; that is, the period will not be included in T. For example, if the T listening period can be an integer multiple of the configured Cell DTX period, and the first and third Cell DTX periods have SI window scheduling, but the second Cell DTX period does not, then the second Cell DTX period will not be included in the T calculation. In other words, if the T listening period is twice the configured Cell DTX period, then T will continue until the end of the third Cell DTX period, not until the second Cell DTX period.
[0267] In some embodiments, the steps and their optional implementations in other embodiments described before or after this embodiment, as well as other related parts in the specification, can be referred to, and will not be repeated here.
