[0050] For ease of understanding, the following describes some aspects of the embodiments of this application:

[0051] I. Introduction to Network Energy Saving (NES) in Release 19 (R19)

[0052] Network energy conservation is crucial for environmental sustainability, reducing environmental impacts (e.g., greenhouse gas emissions), and saving operating costs. With the advent of 5G (5G) technology... th With the widespread adoption of 5G across various industries and geographic regions, the processing of more advanced services and applications requiring extremely high data rates (e.g., extended reality, XR) is leading to denser networks using more antennas, greater bandwidth, and more frequency bands. The environmental impact of 5G needs to be controlled, and new solutions are needed to improve network energy efficiency. To this end, the 3rd Generation Partnership Project (3GPP) initiated network energy efficiency projects in Release 18 and Release 19, outlining several energy-saving directions. One of these is on-demand System Information Block 1 (SIB1) for IDLE / INACTIVE User Equipment (UE). This means SIB1 can be sent on demand based on the UE's needs. Furthermore, to prevent UEs from arbitrarily requesting SIB1, the triggering conditions need to be defined.

[0053] II. Introduction to the Random Access Channel (RACH) Process for On-Demand Other System Information (OSI)

[0054] A cell provides the broadcast status (broadcasting or not broadcasting) for each OSI message in SIB1. If a UE in this cell needs a particular OSI message and the broadcast status of that OSI message is not broadcasting, the UE will send a request to the network (as shown in step 1 of Figure 2). After receiving the request, the network will send a response to the UE (as shown in step 2 of Figure 2). It is worth noting that the resources used to send the request in step 1 are configured in step 0 of Figure 2, specifically in SIB1 of this cell.

[0055] III. Introduction to Short Messages

[0056] The usage of each bit or field in the short message is shown in Table 1:

[0057] Table 1

[0058] IV. Introduction to several cases of R19 OD-SIB1

[0059] For example, the definition of a cell can include the following two types:

[0060] Cell A: A cell that periodically transmits at least its own SIB1.

[0061] NES Cell: A cell that may transmit SIB1 transmission in response to an uplink (UL) wake-up signal (WUS) from a UE.

[0062] Regarding which cell the UE transmits UL WUS to, the following two options can be included:

[0063] Option 1: UE transmits UL WUS to NES Cell;

[0064] Option 2: UE transmits UL WUS to Cell A.

[0065] Regarding which cell offers UL WUS configuration, the following two options can be included:

[0066] Option A: The UE obtains the UL WUS configuration from the NES Cell.

[0067] Option B: The UE obtains the UL WUS configuration from Cell A.

[0068] Regarding which cell the UE receives the on-demand SIB1 from the NES cell, the following two options can be included:

[0069] Option X: UE receives on-demand SIB1 from NES Cell;

[0070] Option Y: The UE receives on-demand SIB1 from Cell A.

[0071] For the combinations of the above options, some possible combinations may include the following:

[0072] Case 1: Option 1+Option A+Option X;

[0073] case 2:Option 1+Option B+Option X;

[0074] case 3:Option 2+Option B+Option Y.

[0075] It should be noted that UL WUS is used to request on-demand SIB1 for the NES cell, which is similar to step 1 shown in Figure 2.

[0076] It should also be noted that the modification period involved in the embodiments of this application can be understood as the period for modifying system information or broadcast messages.

[0077] The transmission method provided in this application will be described in detail below with reference to the accompanying drawings, through some embodiments and application scenarios.

[0078] Please refer to Figure 3, which is a flowchart of a transmission method provided in an embodiment of this application. This method can be executed by a terminal, and as shown in Figure 3, it includes the following steps:

[0079] Step 301: The first terminal receives the first configuration information from the first cell;

[0080] Wherein, the first configuration information is used by the first terminal to request or instruct at least one of the first cell and the neighboring cells of the first cell to send first information, the second cell includes at least one of the first cell and the neighboring cells of the first cell, and the first information includes at least one of the following: synchronization signal block SSB, system information block SIB1.

[0081] In this embodiment, the first terminal can be any terminal, wherein the first terminal may be camped in the first cell or may not be camped in the first cell. The first cell can be a cell in any state; for example, the first cell can be a cell in a first state, or the first cell can be a cell in a second state. The first information may include, but is not limited to, at least one of SIB1, SSB, etc.

[0082] Optionally, the first state may include, but is not limited to, at least one of the following: the transmission of the first information requires a terminal request, the first information is not transmitted, the first information is not continuously transmitted, the first information is not being transmitted, the first information is not being periodically broadcast, the first information is not indicated to be periodically broadcast, the first information is not periodically broadcast, the first information is not indicated to be transmitted, and the first information is in a power-saving state.

[0083] And / or,

[0084] The second state may include, but is not limited to, at least one of the following: the transmission of the first information does not require a terminal request, the first information is being sent, the first information is being continuously sent, the first information is being sent, the first information is being periodically broadcast, the first information is being periodically broadcast, the first information is being sent, and the energy-saving state is not.

[0085] The statement "not always sending the first message" can be understood as "will not always provide the first message." The statement "always sending the first message" can be understood as "will always provide the first message."

[0086] The phrase "not currently transmitting the first information" means, for example, not transmitting the first information within a time period, a time window, or the runtime of a timer, or not temporarily transmitting the first information. The phrase "currently transmitting the first information" means, for example, transmitting the first information within a time period, a time window, or the runtime of a timer, or temporarily transmitting the first information. The duration of the aforementioned time period, time window, or timer can be a finite duration, such as 320ms, or it can be an infinite duration.

[0087] The phrase "not periodically broadcasting the first information" can be understood as not periodically broadcasting the first information within a time period, a time window, or the running time of a timer. The phrase "currently broadcasting the first information" can be understood as periodically broadcasting the first information. For example, if a cell is not periodically broadcasting the first information, it indicates that the cell is in state one; if the cell is periodically broadcasting the first information, it indicates that the cell is in state two.

[0088] The statement "not indicating that the first information is being periodically broadcast" can be understood as no instruction to indicate that the first information is being periodically broadcast has been sent. The statement "indicating that the first information is being periodically broadcast" can be understood as an instruction to indicate that the first information is being periodically broadcast has been sent. For example, if a cell does not indicate that it is periodically broadcasting the first information, it means that the cell is in state one; if a cell indicates that it is periodically broadcasting the first information, it means that the cell is in state two.

[0089] The aforementioned indication that the first information is not periodically broadcast can be understood as sending an indication that the first information is not being periodically broadcast. For example, if a cell indicates that it is not periodically broadcasting the first information, it means that the cell is in the first state.

[0090] The statement "not indicating that it is transmitting the first message" can be understood as "no instruction to indicate that it is transmitting the first message has been sent." The statement "indicating that it is transmitting the first message" can be understood as "an instruction to indicate that it is transmitting the first message has been sent." For example, if a cell does not indicate that it is transmitting the first message, it means that the cell is in state one; if the cell indicates that it is transmitting the first message, it means that the cell is in state two.

[0091] For example, the first cell may include at least one of the following:

[0092] A residential community that is in an energy-saving state, or a residential community that is not in an energy-saving state;

[0093] The transmission of the first information requires a cell requested by the terminal, or the transmission of the first information does not require a cell requested by the terminal.

[0094] Cells that did not send the first message, or cells that sent the first message;

[0095] Cells that do not consistently send the first message, or cells that consistently send the first message;

[0096] The cell is not currently sending the first message, or the cell is currently sending the first message;

[0097] The community is either in state one or state two.

[0098] Cells that do not periodically send the first message, or cells that periodically send the first message.

[0099] The aforementioned first configuration information may include, but is not limited to, at least one of the following: configuration information for requesting the cell to send first information, configuration information for receiving first information, etc. In some embodiments, the aforementioned first configuration information may also be referred to as UL WUS configuration, configuration for requesting the network to send SSB and / or SIB1. Exemplarily, the aforementioned first configuration information may be carried in at least one of the following: broadcast messages and proprietary signaling messages. The aforementioned broadcast messages may include, but are not limited to, at least one of the following: Master Information Block (MIB), SIB1, existing defined OSI, newly defined OSI, etc.

[0100] For example, when the first terminal receives the first configuration information, it may request or instruct some or all of the cells of the second cell to change from the first state to the second state or to send the first information based on the first configuration information, and then the second cell that receives the request or instruction may send the first information.

[0101] In this embodiment, a first terminal receives first configuration information from a first cell. The first configuration information is used to request or instruct at least one of the first cell and its neighboring cells to send first information. The first information includes at least one of the following: SSB, SIB1. Because this embodiment configures the first terminal with configuration information (i.e., first configuration information) for requesting or instructing at least one of the first cell and its neighboring cells to send first information via the first cell, the first terminal can request or instruct at least one of the first cell and its neighboring cells to send first information based on the first configuration information. This helps to ensure communication performance while achieving network energy saving.

[0102] Optionally, the first cell includes at least one of the following:

[0103] Residential communities that are in an energy-saving state;

[0104] The transmission of the first information requires a cell requested by the terminal;

[0105] Cells that did not send the first information;

[0106] The cell that did not continuously send the first information;

[0107] The cell is not currently sending the first message.

[0108] In this embodiment, the first cell is a cell in a first state, that is, the first terminal obtains the first configuration information from the cell in the first state to request or instruct the second cell to send the first information, which is beneficial to network energy saving.

[0109] Optionally, the first cell may configure new cellReselectionPriority and / or new cellReselectionSubPriority parameters for terminals that have the ability to request the network to send first information.

[0110] Optionally, the first configuration information includes at least one of the following:

[0111] The total number of random access preambles in the second cell (totalNumberOfRA-Preambles) or the total number of two-step random access preambles in the second cell (msgA-TotalNumberOfRA-Preambles);

[0112] Configuration information related to ROs that are different from the first random access opportunity (RACH Occasion, RO), where the first RO includes all ROs in the second cell used for connected state terminals to initiate random access;

[0113] Proprietary RO configuration information;

[0114] Information related to the modification period of the second cell;

[0115] The second cell's Extended Discontinuous Reception (eDRX) acquires information related to the acquisition period boundary.

[0116] When the second cell is sending the first information, the first terminal receives the time information of the first information;

[0117] Information on the control resource set (CORESET) used to receive the random access response (RAR), wherein the reference point of the CORESET indicated by the CORESET information is one of the following: resource block (RB) 0 of the carrier of the second cell, the first RB of the carrier of the second cell, the RB with the smallest number in the carrier of the second cell, and the RB with the lowest number in the carrier of the second cell.

[0118] First time-domain information for receiving first information, the first time-domain information including at least one of period, offset, and duration;

[0119] Second time-domain information for receiving first information, wherein the second time-domain information is used to indicate at least one of a specific period and a specific duration for receiving the first information;

[0120] The second cell includes at least one of the first cell and the neighboring cells of the second cell.

[0121] For example, the parameter totalNumberOfRA-Preambles can represent the total number of preambles used for contention-free or contention-free 4-step or 2-step random access in the RACH resources defined in the RACH-ConfigCommon configuration, excluding preambles used for other purposes, such as preambles used for System Information (SI) requests; or, it can represent the total number of preambles used for contention-free random access in the RACH resources defined in the CFRA configuration, excluding preambles used for other purposes, such as preambles used for SI requests.

[0122] For example, the information related to the modification period mentioned above may include, but is not limited to, the value of m of the modification period boundaries or parameters used to calculate the value of m. Here, m represents the total number of radio frames included in a modification period, and the parameters used to calculate the value of m may include at least one of the modification period coefficient (modificationPeriodCoeff) and the default paging cycle (defaultPagingCycle), where m = modificationPeriodCoeff * defaultPagingCycle.

[0123] For example, the time information for the first terminal to receive the first information may include, but is not limited to, at least one of the following: start time point, end time point, listening time length, or listening time window. In some optional embodiments, the time information for the first terminal to receive the first information may include at least one of first time information and second time information, wherein the first time information is the time information used to receive the first information when the second cell is sending the first information for a first reason, and the second time information is the time information used to receive the first information when the second cell is sending the first information for a second reason. The first reason is that the second cell receives a request or indication from the second terminal to change from a first state to a second state. The second terminal is any terminal different from the first terminal. The second reason is that the second cell sends a short message, such as a short message with the systemInfoModification field set to 1, and / or a short message with the etwsAndCmasIndication field set to 1, etc.

[0124] The aforementioned second time-domain information is used to indicate at least one of a specific period and a specific duration for receiving the first information. That is, the terminal can determine, based on the second time-domain information, in which specific period or duration it receives the information from the second cell. For example, the aforementioned second time-domain information is used to indicate that the first terminal receives the first information from the second cell in the T-th period or duration after a third time point. The third time point includes the following: the time point when the third information is sent, the time point when the first RAR is received, or the time point when the random access response window (ra-ResponseWindow) is started; the time point when the first RAR is received is offset by P time units; the time point when the ra-ResponseWindow ends or times out; and the time point when the ra-ResponseWindow ends or times out is offset by S time units; T, P, and S are all positive integers. For example, the aforementioned second time-domain information can be absolute time information, which determines in which period or duration the first information from the second cell is received.

[0125] Optionally, the first configuration information may further include second information;

[0126] And / or,

[0127] The method further includes: the first terminal receiving second information from the second cell;

[0128] The second information is used to indicate whether the second cell is sending the first information.

[0129] The aforementioned second community includes at least one of the first community and the second community.

[0130] In some scenarios, after receiving a UL WUS from UE1, an NES Cell can temporarily send SIB1 within a time window. If UE2 is aware that the NES Cell is temporarily sending SIB1, it can directly receive the SIB1 from the NES Cell without sending a UL WUS. In other scenarios, if an NES Cell sends a short message, it will proactively send SIB1 without requiring a request from a UE residing in the NES Cell. UEs residing in the NES Cell can directly receive the SIB1 from the NES Cell if needed.

[0131] Based on this, this embodiment can use the second information to indicate whether the second cell is sending the first information. If the second information indicates that the second cell is sending the first information, the first terminal can directly receive the first information from the second cell if it needs it. Otherwise, the first terminal needs to send UL WUS to request the second cell to send the first information if it needs it. In some optional embodiments, the above-mentioned second information can be used to indicate at least one of the following: whether the second cell is sending the first information for a first reason, wherein the first reason is that the second cell receives a request or indication from the second terminal to change from a first state to a second state; or whether the second cell is sending the first information for a second reason, wherein the second reason is that the second cell has sent a short message.

[0132] In some implementations, the second information can be carried in the first configuration information. This not only ensures that the first terminal can easily know whether the second cell is sending the first information, but also helps to save signaling overhead since the second information is located in the first configuration information.

[0133] In some implementations, the first terminal receives the second information from the first cell. For example, the second information and the first configuration information can be carried in different signaling, or the second information and the first configuration information can be carried in the same signaling but located in different indication domains. This not only ensures that the first terminal can conveniently know whether the second cell is sending the first information, but also helps to improve the flexibility of indicating the second information.

[0134] Optionally, the second information is indicated by at least one of the following:

[0135] At least one of MIB and Physical Broadcast Channel (PBCH);

[0136] System Information Block (SIB);

[0137] First proprietary signaling.

[0138] For example, the aforementioned second information may be carried in at least one of the MIB, PBCH, SIB, and first proprietary signaling. The aforementioned first proprietary signaling may include, but is not limited to, at least one of the following: Radio Resource Control (RRC) messages, Media Access Control Control Element (MAC CE) messages, and newly defined proprietary signaling messages.

[0139] In some optional embodiments, changes to the second information do not cause the first or second cell to send a short message; that is, if the first or second cell changes the content of the second information, the first or second cell will not send a short message (e.g., a short message used to notify the system of information changes) to notify the UE. Optionally, if the second information read by the UE indicates that the second cell is sending the first information, the UE considers the content of the second information to be valid until the end of the current modification period.

[0140] In some optional embodiments, a change in the second information will cause the first cell or the second cell to send a short message. That is, if the first cell or the second cell changes the content of the second information, the first cell or the second cell will send a short message to notify the UE. For example, the change in the second information can be indicated by at least one bit in the unused bits (such as bits 5-8) of the short message.

[0141] Optionally, the second information is indicated by at least one of the MIB and PBCH, including indicating the second information by at least one of the following:

[0142] The MIB includes the spare field, the synchronization block subcarrier offset (ssb-SubcarrierOffset) field, the kSSB value determined based on the MIB and the PBCH, the kSSB value determined based on the MIB, the cellBarred field, the intraFreqReselection field, the physical downlink control channel SIB1 configuration (pdcch-ConfigSIB1) field, the subcarrierSpacingCommon field, the Type A demodulation reference signal position (dmrs-TypeA-Position) field, and the system frame number field.

[0143] The kSSB value mentioned above can represent the subcarrier offset (ssb-SubcarrierOffset).

[0144] The following examples illustrate this embodiment:

[0145] Example 1: The second information is indicated by the 1-bit spare field of the MIB. For example, when the spare field is 1, it means that the second cell is sending the first information; when the spare field is 0, it means that the second cell is not sending the first information.

[0146] Example 2: The second information can be indicated by the ssb-SubcarrierOffset field of the MIB. For example, when ssb-SubcarrierOffset is equal to x, it means that the second cell is sending the first information. x can be a value predefined by the protocol or a value configured by the network-side device.

[0147] Example 3: The second information is indicated by the kSSB value determined based on MIB and PBCH. For example, when the kSSB value determined based on MIB and PBCH is equal to 30, it indicates that the second cell is sending the first information.

[0148] Example 4: The second information is indicated by the kSSB value determined based on MIB. For example, when the kSSB value determined based on MIB is equal to 14, it indicates that the second cell is sending the first information.

[0149] Example 5: The second information can be indicated by the cellBarred or intraFreqReselection field of the MIB. For example, when the cellBarred or intraFreqReselection field is set to allowed, it means that the second cell is sending the first information; when the cellBarred or intraFreqReselection field is set to notAllowed, it means that the second cell is not sending the first information.

[0150] Example 6: The second information can be indicated by the pdcch-ConfigSIB1 field of the MIB. For example, the second information can be indicated by at least one bit of the 8-bit pdcch-ConfigSIB1 field.

[0151] Example 7: The second information can be indicated by the subCarrierSpacingCommon field of the MIB. For example, the second cell can be indicated to be transmitting the first information by setting the value of the subcarrier space (SCS) to 15 or 60, and the second cell can be indicated not to be transmitting the first information by setting the value of the SCS to 30 or 120.

[0152] Example 8: The second information can be indicated by the dmrs-TypeA-Position field of the MIB. For example, the second cell can be indicated to be sending the first information by setting the dmrs-TypeA-Position field to pos2, and the second cell can be indicated to be not sending the first information by setting the dmrs-TypeA-Position field to pos3.

[0153] Example 9: The second information can be indicated by the systemFrameNumber field of the MIB. For example, the second information can be indicated by at least one bit of the 6-bit systemFrameNumber field.

[0154] Example 10: At least two of the following fields in the MIB indicate the second information: the spare field of the MIB, the ssb-SubcarrierOffset field of the MIB, the kSSB value determined based on the MIB and the PBCH, the cellBarred field of the MIB, the intraFreqReselection field of the MIB, the pdcch-ConfigSIB1 field of the MIB, the subCarrierSpacingCommon field of the MIB, the dmrs-TypeA-Position field of the MIB, and the systemFrameNumber field of the MIB. For example, the spare field of the MIB indicates whether the second cell is sending the first information for the first reason, and the ssb-SubcarrierOffset field of the MIB indicates whether the second cell is sending the first information for the second reason.

[0155] This embodiment uses at least one of the following fields to indicate the second information: the spare field of the MIB, the ssb-SubcarrierOffset field of the MIB, the kSSB value determined based on the MIB and the PBCH, the cellBarred field of the MIB, the intraFreqReselection field of the MIB, the pdcch-ConfigSIB1 field of the MIB, the subCarrierSpacingCommon field of the MIB, the dmrs-TypeA-Position field of the MIB, and the systemFrameNumber field of the MIB. For example, the first bit of the pdcch-ConfigSIB1 field indicates whether the second cell is sending the first information for the first reason, and the first bit of the ssb-SubcarrierOffset field of the MIB indicates whether the second cell is sending the first information for the second reason.

[0156] Optionally, the method further includes at least one of the following:

[0157] If the value of the first field in the MIB is a first value, the first terminal does not send the first request to the second cell;

[0158] When at least one bit of the second field in the MIB has a second value, the first terminal does not send the first request to the second cell.

[0159] If the kSSB value determined based on the MIB and the PBCH is a third value, the first terminal does not send the first request to the second cell.

[0160] The first request is used to request the second cell to send the first information.

[0161] For example, the first field mentioned above may include, but is not limited to, at least one of the following: the MIB's spare field, ssb-SubcarrierOffset field, cellBarred field, intraFreqReselection field, pdcch-ConfigSIB1 field, subCarrierSpacingCommon field, dmrs-TypeA-Position field, and systemFrameNumber field. The first value corresponds to the first field. For example, if the first field includes the ssb-SubcarrierOffset field, then the first value may include 14.

[0162] For example, the second field may include, but is not limited to, at least one of the following: the ssb-SubcarrierOffset field, the pdcch-ConfigSIB1 field, the subCarrierSpacingCommon field, the dmrs-TypeA-Position field, and the systemFrameNumber field of the MIB. At least one bit of the aforementioned second field, for example, the first bit of the pdcch-ConfigSIB1 field, all bits of the ssb-SubcarrierOffset field, etc. The aforementioned second value corresponds to the second field; for example, if at least one bit of the second field is all bits of the ssb-SubcarrierOffset field, the aforementioned second value may be 14.

[0163] For example, the third value mentioned above may include, but is not limited to, 30 or 14.

[0164] In this embodiment, since the value of the first field in the MIB is a first value, or the value of at least one bit of the second field in the MIB is a second value, or the value of kSSB determined by the MIB and the PBCH is a third value, it indicates that the second cell is sending the first information. Therefore, the terminal does not need to request the second cell to send the first information, but can directly receive the first information of the second cell.

[0165] Optionally, the method further includes:

[0166] When the first terminal needs the first information of the second cell, and the second information indicates that the second cell is sending the first information, the first terminal receives the first information of the second cell.

[0167] The aforementioned requirement of the first terminal for the first information of the second cell can also be referred to as the expectation of the first terminal to receive the first information of the second cell. For example, when the first terminal needs to determine the broadcast status of the OSI message, it means that the first terminal needs the first information of the second cell; or, when the first terminal needs the first information during the cell reselection process to determine whether a cell can be camped, it means that the first terminal needs the first information of the second cell.

[0168] The aforementioned second information may be carried in the first configuration information or the MIB of the first or second cell. For example, if the second information is carried in the MIB of the second cell, and the first terminal needs the first information of the second cell, the first terminal may first read or obtain the MIB of the second cell, obtain the second information based on the MIB of the second cell, and if the second information indicates that the second cell is sending the first information, the first terminal receives the first information of the second cell.

[0169] For example, the first terminal may determine the physical downlink control channel (PDCCH) for receiving the first information from the second cell based on configuration information used for receiving the first information in the first configuration information (such as the kSSB value determined by the absolute radio frequency channel number (ARFCN-ValueNR) and absolute frequency point A (absoluteFrequencyPointA) of the first configuration information, pdcch-ConfigSIB1 of the first configuration information, etc.) or based on at least one of the kSSB value determined by the MIB and / or PBCH of the second cell and pdcchConfigSIB1.

[0170] In this embodiment, when the first terminal needs the first information of the second cell and the second information indicates that the second cell is sending the first information, the first terminal can directly receive the first information of the second cell without requesting the second cell to change from the first state to the second state. This not only helps the first terminal to obtain the first information of the second cell in a timely manner, but also helps to save resource consumption.

[0171] Optionally, when the first terminal needs the first information of the second cell, and the second information indicates that the second cell is sending the first information, the first terminal receiving the first information of the second cell includes at least one of the following:

[0172] When the first terminal needs the first information of the second cell, and the second information indicates that the second cell is sending the first information, the first terminal immediately begins to receive the first information of the second cell, or, starts to receive the first information of the second cell from a first time point, the first time point including at least one of the following: the start point of the next modification cycle, the start point of the boundary of the next eDRX collection cycle;

[0173] When the first terminal needs the first information of the second cell, the first terminal reads or confirms the second information, and when the second information indicates that the second cell is sending the first information, the first terminal receives the first information of the second cell;

[0174] When the first terminal needs the first information of the second cell, and the second information indicates that the second cell is sending the first information, the first terminal receives the first information of the second cell until it receives the first information of the second cell at or before the second time point or reaches the second time point; wherein, the second time point includes at least one of the following: the end point of the current modification period, the end point of the next modification period, the end point of the Nth modification period after the current modification period, the end point of the boundary of the current eDRX collection period, the end point of the boundary of the next eDRX collection period, the end point of the boundary of the Kth eDRX collection period after the boundary of the current eDRX collection period, and the time point determined according to the time information of the first terminal receiving the first information in the first configuration information, where N and K are both positive integers;

[0175] When the first terminal needs the first information of the second cell, and the second information indicates that the second cell is sending the first information, the first terminal receives the first information within a first range; wherein, the first range includes a first time period or the running time period of a first timer or a first window.

[0176] In this embodiment, the values ​​of N and K can be predefined by the protocol or configured by the network side. For example, the values ​​of N and K can be carried in the first configuration information. The first time period, the running time period of the first timer, or the first window can be predefined by the protocol or configured by the network-side device.

[0177] The following examples illustrate this embodiment:

[0178] Example 1: When the first terminal needs the first information from the second cell, and the second information indicates that the second cell is transmitting the first information, the first terminal immediately begins receiving the first information from the second cell, or begins receiving the first information from the second cell from a first time point. In this example, a limitation is made on when the first terminal begins receiving the first information from the second cell, which helps the first terminal to receive the first information from the second cell more accurately.

[0179] Example 2: When the first terminal needs the first information of the second cell, the first terminal first reads or confirms the second information, and when the second information indicates that the second cell is transmitting the first information, the first terminal receives the first information of the second cell. In this example, when the first terminal needs the first information of the second cell, because the first terminal reads or confirms the second information first, it can determine whether it can directly receive the first information of the second cell based on the latest second information, which can improve the success rate of the first terminal receiving the first information of the second cell.

[0180] Example 3: When the first terminal needs the first information from the second cell, and the second information indicates that the second cell is transmitting the first information, the first terminal receives the first information from the second cell until it receives the first information from the second cell at or before the second time point, or until the second time point is reached. This limitation on when the first terminal stops receiving the first information from the second cell helps it to receive the first information from the second cell more accurately.

[0181] Example 4: When the first terminal needs the first information of the second cell, and the second information indicates that the second cell is transmitting the first information, the first terminal receives the first information of the second cell within a first range. In this example, the time range within which the first terminal receives the first information of the second cell is specified, which helps the first terminal to receive the first information of the second cell more accurately.

[0182] Example 5: When the first terminal needs the first information from the second cell, and the second information indicates that the second cell is transmitting the first information, the first terminal immediately begins receiving the first information from the second cell, or, starts receiving the first information from the second cell from a first time point until it receives the first information from the second cell at or before the second time point, or reaches the second time point. In this example, the timing of when the first terminal begins and ends receiving the first information from the second cell is specified, which helps the first terminal to receive the first information from the second cell more accurately.

[0183] Example 6: When the first terminal needs the first information from the second cell, and the second information indicates that the second cell is transmitting the first information, the first terminal immediately begins receiving the first information from the second cell, or, begins receiving the first information from the second cell from a first time point until the first information is received within a first range or the end point of the first range is reached. The start point of the first range can be the time point at which the first terminal begins receiving the first information from the second cell. In this example, the timing and time period during which the first terminal begins receiving the first information from the second cell are specified, which helps the first terminal to receive the first information from the second cell more accurately.

[0184] Example 7: When the first terminal needs the first information of the second cell, the first terminal reads or confirms the second information. If the second information indicates that the second cell is transmitting the first information, the first terminal immediately begins receiving the first information of the second cell, or it begins receiving the first information of the second cell from a first time point until it receives the first information of the second cell at or before the second time point, or reaches the second time point. In this example, when the first terminal needs the first information of the second cell, because the first terminal reads or confirms the second information first, it can determine whether it can directly receive the first information of the second cell based on the latest second information, which can improve the success rate of the first terminal receiving the first information of the second cell. Furthermore, the timing of when the first terminal begins and ends receiving the first information of the second cell is specified, which helps the first terminal to receive the first information of the second cell more accurately.

[0185] Optionally, the first terminal receives the first information from the second cell, including at least one of the following:

[0186] Receive the first information of the second cell according to the full content of the first target configuration information;

[0187] Receive the first information of the second cell based on a portion of the first target configuration information;

[0188] The first information of the second cell is received using the latest pdcch-ConfigSIB1 field read or obtained, wherein the pdcch-ConfigSIB1 field is the pdcch-ConfigSIB1 field in the MIB of the second cell.

[0189] If the kSSB value determined based on the MIB and / or PBCH of the second cell is the fourth value, the first information of the second cell is received according to the full content of the first target configuration information;

[0190] If the kSSB value determined based on the MIB and / or PBCH of the second cell is the fifth value, the first information of the second cell is received according to a portion of the first target configuration information;

[0191] The first target configuration information includes the following: the latest second configuration information currently obtained, the second configuration information already received, the latest second configuration information already received, the second configuration information read or obtained, and the latest second configuration information read or obtained; the second configuration information is the configuration information in the first configuration information used to receive the first information of the second cell.

[0192] For example, the fourth value mentioned above may include, but is not limited to, any one of 24 to 29 and 31. The fifth value mentioned above may include, but is not limited to, 30. For example, the kSSB value mentioned above may be indicated by 4 bits of the MIB and 1 bit of the PBCH.

[0193] For example, when the first information is SIB1, the entire contents of the first target configuration information may include the kSSB value and pdcch-ConfigSIB1, etc., and a portion of the contents of the first target configuration information may include the kSSB value.

[0194] The following examples illustrate this embodiment:

[0195] Example 1: A first terminal can receive the first information of the second cell based on the first target configuration information when it needs the first information of the second cell and the second information indicates that the second cell is sending the first information. For example, if all the contents of the second configuration information remain unchanged, the first terminal can receive the first information of the second cell based on all the contents of the first target configuration information; if only part of the second configuration information remains unchanged, the first terminal can receive the first information of the second cell based on only part of the first target configuration information.

[0196] Example 2: When the first terminal needs the first information of the second cell and the second information indicates that the second cell is sending the first information, the first terminal can first read or obtain the latest MIB of the second cell, and receive the first information of the second cell according to the pdcch-ConfigSIB1 field in the MIB of the second cell.

[0197] Example 3: When the first terminal needs the first information of the second cell and the second information indicates that the second cell is sending the first information, it can first read or obtain the latest MIB and / or PBCH of the second cell. If the kSSB value determined based on the MIB and / or PBCH of the second cell is the fourth value, it means that all the contents of the second configuration information remain unchanged. In this case, the first information of the second cell can be received according to all the contents of the first target configuration information. If the kSSB value determined based on the MIB and / or PBCH of the second cell is the fifth value, it means that part of the contents of the second configuration information remains unchanged. In this case, the first information of the second cell can be received according to part of the contents of the first target configuration information.

[0198] Optionally, the method further includes:

[0199] The first terminal sends third information to the second cell, wherein the third information is used to request or instruct the second cell to send first information.

[0200] The second cell includes at least one of the first cell and the neighboring cells of the first cell.

[0201] For example, the third information mentioned above may include a preamble. For instance, the terminal may send a preamble to the second cell via Msg1 or MsgA, which is used to request or instruct the second cell to send the first information.

[0202] Optionally, the MAC subPDU corresponding to the preamble of the third information satisfies at least one of the following:

[0203] The length of the MAC sub-protocol data unit (subPDU) corresponding to the preamble of the third information is the same as the length of the MAC subPDU corresponding to the preamble used for OSI requests, for example, both are 1 byte.

[0204] The format of the MAC subPDU corresponding to the preamble of the third information is the same as the format of the MAC subPDU corresponding to the preamble used for OSI requests. For example, the MACE subheader only includes the Random Access Preamble Identifier (RAPID), that is, it only has three fields: Extension (E), Type (T) and RAPID.

[0205] Optionally, if R SSBs of the NES cell are associated with a RACH opportunity for a UL-WUS / first information request, where R ≥ 1, then for the J-th SSB (J = 0, ..., R-1), a preamble index = RA - PreambleStartIndex + J is used for the first information (e.g., OD-SIB1) request. For M < 1, a preamble index = RA - PreambleStartIndex is used for the first information (e.g., OD-SIB1) request.

[0206] For example, the first terminal may send third information to the second cell if the first condition is met.

[0207] For example, the first condition may include: the second cell did not send the first information.

[0208] In some embodiments, the aforementioned third information may also be referred to as UL WUS.

[0209] Optionally, the method further includes at least one of the following:

[0210] The first terminal receives a first RAR, and the CORESET used by the first terminal to receive the first RAR is either a first CORESET or a second CORESET, and / or the first RAR includes at least one of the following: first time-domain information for receiving first information, and second time-domain information for receiving the first information; wherein, the first CORESET is the CORESET indicated by the CORESET information for receiving the RAR in the first configuration information, and the reference point of the first CORESET is one of the following: RB0 of the carrier of the second cell, the first RB of the carrier of the second cell, the RB with the smallest number among the carriers of the second cell, and the RB with the lowest number among the carriers of the second cell; the second CORESET is a protocol-predefined CORESET or a default CORESET; the first time-domain information includes at least one of period, offset, and duration; the second time-domain information is used to indicate at least one of a specific period and a specific duration for receiving the first information; the first RAR is the RAR corresponding to the third information;

[0211] The first terminal does not stop the random access response window (ra-ResponseWindow) after receiving the first RAR;

[0212] The first terminal receives the first information from the second cell;

[0213] If the second cell is determined to be a suitable cell based on the first information of the second cell, the first terminal camps on the second cell.

[0214] The second cell includes at least one of the first cell and the neighboring cells of the first cell.

[0215] The second time-domain information mentioned above can be found in the relevant descriptions of the foregoing embodiments, and will not be repeated here.

[0216] For example, the second CORESET can be CORESET0.

[0217] The following examples illustrate this embodiment:

[0218] Example 1: The first terminal sends third information to the second cell, receives the first RAR from the second cell, receives the first information from the second cell after receiving the first RAR, and if the first terminal determines that the second cell is a suitable cell based on the first information of the second cell, the first terminal camps on the second cell.

[0219] Example 2: When the second cell is sending the first information, the first terminal can directly receive the first information from the second cell, and if the first terminal determines that the second cell is a suitable cell based on the first information from the second cell, the first terminal camps on the second cell.

[0220] It is understandable that if the first terminal is already camped in the second cell, after receiving the first information from the second cell, the first terminal may not perform the subsequent operation of camping in the second cell.

[0221] In some optional embodiments, the first terminal receives the first RAR from the second cell using a first Radio Network Temporary Identity (RNTI). The first RNTI is different from the RNTI of related technologies. For example, the RNTI of related technologies may include a Random Access Radio Network Temporary Identity (RA-RNTI).

[0222] Optionally, the first terminal receives the first information from the second cell, including at least one of the following:

[0223] The first terminal receives the first information of the second cell based on the first time-domain information in the first configuration information or the first time-domain information in the first RAR;

[0224] The first terminal receives the first information of the second cell based on the second time-domain information in the first configuration information or the second time-domain information in the first RAR;

[0225] The first terminal receives the first information of the second cell during the Tth period or duration after the third time point;

[0226] The third time point includes the following: the time point when the third information is sent, the first RAR is received, or the ra-ResponseWindow is started; the time point when the first RAR is received is offset by P time units; the time point when the ra-ResponseWindow ends or times out; and the time point when the ra-ResponseWindow ends or times out is offset by S time units; T, P, and S are all positive integers.

[0227] In this embodiment, the first terminal receives the first information of the second cell based on at least one of the first time domain information, the second time domain information, and the Tth period or duration after the third time point. This helps the first terminal to receive the first information of the second cell more accurately, thereby saving energy while ensuring the successful reception of the first information of the second cell.

[0228] Optionally, if the first terminal is camped in the second cell, and the second cell is the first cell, the method further includes:

[0229] When the first terminal receives a short message from the second cell, the first terminal performs a first operation, which includes at least one of the following: reading or obtaining the MIB of the second cell, and receiving the first information of the second cell.

[0230] The second cell includes at least one of the first cell and the neighboring cells of the first cell.

[0231] For example, the aforementioned short message may include any short message type, such as a short message with the systemInfoModification field set to 1 and / or the etwsAndCmasIndication field set to 1.

[0232] In this embodiment, when the first terminal receives a short message from the second cell, it indicates that the second cell is sending first information. In this case, the first terminal can directly receive the first information from the second cell. For example, the first terminal can read or obtain the MIB of the second cell and receive the first information from the second cell based on the MIB of the second cell; or, the first terminal can receive the first information from the second cell based on the configuration information for receiving the first information in the first configuration information, etc. This not only helps the first terminal to obtain the first information from the second cell more timely, but also helps to save system resource overhead.

[0233] In some optional embodiments, when the first terminal receives a short message from the second cell, the method further includes at least one of the following:

[0234] The first terminal assumes that the content of the third configuration information remains completely unchanged;

[0235] The first terminal believes that some content of the third configuration information remains unchanged;

[0236] If the kSSB value determined based on the MIB and / or PBCH of the second cell is the fourth value, the first terminal considers that the content of the third configuration information remains unchanged.

[0237] If the kSSB value determined based on the MIB and / or PBCH of the second cell is the fifth value, the first terminal considers that part of the third configuration information remains unchanged.

[0238] The third configuration information is the configuration information used to receive the first information of the second cell in the first configuration information, and the first configuration information is carried in the system information.

[0239] Optionally, when the first terminal receives a short message from the second cell, the first terminal performs a first operation, including:

[0240] When the first terminal receives a short message from the second cell, the first terminal performs at least one of the following:

[0241] The first information of the second cell is received using the latest pdcch-ConfigSIB1 field read or obtained, wherein the pdcch-ConfigSIB1 field is the pdcch-ConfigSIB1 field in the MIB of the second cell.

[0242] If the kSSB value determined based on the MIB and / or PBCH of the second cell is the fourth value, the first information of the second cell is received using the full content of the second target configuration information;
