[0054] For the convenience of understanding, some contents related to the embodiments of the present application are described as follows:

[0055] I. Introduction of network energy saving (NES) in the nineteenth release (R19)

[0056] Network energy saving is of great significance to environmental sustainability, reduction of environmental impact (for example, greenhouse gas emissions) and cost savings. With the popularity of the fifth generation (5 th Generation, 5G) communication system in various industries and geographical areas, the network becomes more intensive, uses more antennas, larger bandwidth and more frequency bands to handle very high data rates (for example, more advanced services and applications of eXtended reality (XR)). The impact of 5G on the environment needs to be controlled, and new solutions need to be developed to improve network energy saving. To this end, 3GPP has launched a network energy saving project in the eighteenth release (Release 18, R18) and R19, and developed multiple energy saving directions, one of which is on demand for IDLE / INACTIVE UE for system information block 1 (SIB1), that is, SIB1 can be sent on demand according to the needs of UE. And in order to avoid that UE randomly requests SIB1, the trigger condition needs to be defined.

[0057] II. Introduction of random access (RACH) procedure for on demand other system information (OSI)

[0058] A cell will give each OSI broadcast status (broadcasting or not broadcasting) in SIB1. If a UE in this cell needs a certain OSI message and the broadcast status of this OSI message is not broadcasting, the UE will send a request to the network (step 1 in Figure 2), and the network will send a response to the UE after receiving the request (step 2 in Figure 2). It is worth noting that the resources used to send the request in step 1 are configured in step 0 in Figure 2, and the specific method is in the SIB1 of this cell.

[0059] III. Introduction of Short message

[0060] The usage of each bit or field in Short message is shown in Table 1:

[0061] Table 1

[0062] IV. Introduction of several cases of R19 OD-SIB1

[0063] Exemplarily, the definition of a cell can include the following two kinds:

[0064] Cell A (Cell A): a cell that periodically transmits at least its own SIB1;

[0065] NES cell (NES cell): a cell that may transmit SIB1 transmission in response to UL WUS from a UE.

[0066] For which cell the UE transmits UL WUS, the following two options can be included:

[0067] Option 1: UE transmits UL WUS to NES cell;

[0068] Option 2: UE transmits UL WUS to Cell A.

[0069] For the configuration of which Cell provides UL WUS, the following two options can be included:

[0070] Option A: UE obtains the UL WUS configuration from NES Cell;

[0071] Option B: UE obtains the UL WUS configuration from Cell A.

[0072] For the on-demand SIB1 of the NES cell which the UE receives in which Cell, the following two options can be included:

[0073] Option X: UE receives on-demand SIB1 from NES Cell;

[0074] Option Y: UE receives on-demand SIB1 from Cell A.

[0075] For the combination of the above options, some optional combination cases can include the following:

[0076] Case 1: Option 1+Option A+Option X;

[0077] Case 2: Option 1+Option B+Option X;

[0078] Case 3: Option 2+Option B+Option Y.

[0079] It should be noted that the UL WUS is used to request the on-demand SIB1 of the NES cell, which is similar to step 1 shown in FIG. 2.

[0080] The transmission method provided by the embodiments of the present application will be described in detail in combination with some embodiments and application scenarios thereof by the drawings.

[0081] Please refer to FIG. 3, which is a flow chart of a transmission method provided by an embodiment of the present application, which can be executed by a terminal. As shown in FIG. 3, the method comprises the following steps:

[0082] Step 301: The terminal receives a first message of a first cell.

[0083] The first message comprises first configuration information, which is used for the terminal to request or indicate a second cell in a first state to change to a second state.

[0084] In the embodiment, the terminal can camp on the first cell or can not camp on the first cell. The first message can comprise at least one of a broadcast message and a dedicated signaling message, but is not limited thereto. For example, the broadcast message can comprise at least one of a Master Information Block (MIB), a SIB1, an existing defined OSI, a newly defined OSI, and the like.

[0085] The second cell can comprise at least one of the first cell and a neighboring cell of the first cell. It can be understood that the number of cells comprised by the second cell can be one or at least two.

[0086] Optionally, the first state can comprise at least one of the following: the terminal needs to request the transmission of the first information, the first information is not transmitted, and an energy saving state.

[0087] Optionally, the second state can comprise at least one of the following: the first information is transmitted, and a non-energy saving state.

[0088] For example, the first information can comprise at least one of a SIB1, a Synchronous Signal Block (SSB), and the like.

[0089] The first configuration information can comprise at least one of beam information, an application range of the first configuration information, a valid time of the first configuration information, and the like. In some embodiments, the first configuration information can also be referred to as UL WUS configuration.

[0090] For example, when the terminal receives the first configuration information, the terminal can request or indicate part or all of the cells of the second cell to change from the first state to the second state based on the first configuration information, and then the second cell that receives the request or indication can transmit the first information to the terminal.

[0091] In the embodiment of the present application, a terminal receives a first message of a first cell; wherein the first message comprises first configuration information, and the first configuration information is used for the terminal to request or indicate a second cell in a first state to change to a second state. In the embodiment of the present application, the first cell configures configuration information (i.e. the first configuration information) for the terminal to request or indicate the second cell in the first state to change to the second state, and then the terminal can request or indicate part or all of the cells of the second cell to change from the first state to the second state based on the first configuration information, which is beneficial to guarantee the realization of network energy saving.

[0092] Optionally, the first cell comprises at least one of:

[0093] a cell in the energy saving state, or a cell in the non-energy saving state;

[0094] the first information is sent by a cell requested by the terminal, or the first information is not sent by a cell requested by the terminal;

[0095] a cell which does not send the first information, or a cell which periodically sends the first information;

[0096] a cell in the first state, or a cell in the second state.

[0097] Optionally, the second cell is a neighbor cell of the first cell.

[0098] In the embodiment, the second cell is a neighbor cell of the first cell, and it can be understood that in this case, the number of cells comprised by the second cell can also be one or at least two. In the case where the number of cells comprised by the second cell is at least two, at least part of the cells of the second cell can be cells of different base stations, or all of the cells of the second cell can be cells of the same base station. It should be noted that in the case where the number of cells comprised by the second cell is at least two, the second cell can also be described as a second cell group.

[0099] In the embodiment, the first cell configures configuration information for the terminal to request or indicate the neighbor cell (i.e. the second cell) of the first cell to change from the first state to the second state, which is beneficial to the energy saving of the second cell.

[0100] Optionally, the validity of the first message and the validity of the first configuration information are determined respectively.

[0101] In the embodiment, the terminal can determine the validity of the first message and the validity of the first configuration information respectively, that is, the validity of the first message of the first cell and the validity of the first configuration information are related and independent, and the invalidity of the first cell does not mean that the first configuration information is also invalid, which is beneficial to providing flexibility of the validity configuration of the first configuration information.

[0102] Optionally, the validity time of the first message is different from the validity time of the first configuration information.

[0103] And / or,

[0104] The valueTag of the first message is different from the valueTag of the first configuration information.

[0105] In an embodiment, the validity time can be configured or protocol-defined for the first message and the first configuration information respectively.

[0106] For example, in the case that the first message is a broadcast message, the validity time of the first message can be protocol-defined as 3 hours, and the validity time of the first message can be protocol-defined as R hours, and R is not equal to 3.

[0107] In another embodiment, a valueTag can be defined for the first configuration information, and the valueTag is different from the valueTag of the first message. For example, in the case that the first message is an OSI message, a valueTag can be defined for the first configuration information, and the valueTag of the first configuration information can be carried in SIB1 or MIB.

[0108] For determining the validity based on the valueTag, for example, the terminal can read the valueTag value of the first message from SIB1 and compare it with the valueTag value read last time, if the valueTag value changes, it is considered that the content of the first message changes, and the first message is invalid, if the valueTag value does not change, the first message continues to be valid. Similarly, the terminal can read the valueTag value of the first configuration information from SIB1 and compare it with the valueTag value read last time, if the valueTag value changes, it is considered that the content of the first configuration information changes, and the first configuration information is invalid, if the valueTag value does not change, the first configuration information continues to be valid.

[0109] In some optional embodiments, in the case that the first message is an OSI message, the valueTag of the first message is different from the valueTag of the first configuration information.

[0110] Optionally, the first message includes at least one of the following: a first broadcast message, a first dedicated signaling message.

[0111] And / or,

[0112] The first configuration information includes beam information for receiving the first information, or the first configuration information includes beam information for receiving the first information and the validity period of the first configuration information.

[0113] For example, the aforementioned first broadcast message may include, but is not limited to, at least one of MIB, SIB1, existing defined OSI, newly defined OSI, etc. The aforementioned first proprietary signaling message may include, but is not limited to, at least one of Radio Resource Control (RRC) messages, Media Access Control Control Element (MAC CE), newly defined proprietary signaling messages, etc.

[0114] For example, the beam information for receiving the first information may include beam information corresponding to at least one preamble, such as beam information corresponding to preamble 1 and beam information corresponding to preamble 2. In this case, if the UE uses preamble 1, the UE will receive the first information on the beam corresponding to preamble 1.

[0115] Optionally, the method further includes:

[0116] The terminal receives second information from the first cell, the second information being used to determine the Public Land Mobile Network (PLMN) to which the first configuration information applies.

[0117] In this embodiment, the second information is used to determine the PLMN to which the first configuration information applies. For example, the second information may include the PLMN identifier to which the first configuration information applies. In this way, the terminal can request or indicate to the cell of its applicable PLMN to change from the first state to the second state based on the first configuration information, which helps the terminal to wake up the required cell more accurately.

[0118] Optionally, the second information is carried in at least one of the following: a second broadcast message, a second proprietary signaling message.

[0119] For example, the aforementioned second broadcast message may include, but is not limited to, at least one of MIB, SIB, etc.

[0120] For example, the aforementioned second proprietary signaling message may include, but is not limited to, at least one of RRC messages, MAC CE, newly defined proprietary signaling messages, etc.

[0121] Optionally, the method further comprises:

[0122] The terminal receives third information from the first cell, or the terminal receives third information from the second cell, the third information being used to indicate at least one of the following: indicating whether the second cell is sending the first information; whether the second cell supports the first event.

[0123] In this embodiment, the terminal receives third information from the first cell or the second cell, and then can determine whether to request or indicate the second cell to transition from the first state to the second state according to the third information, which is conducive to improving the accuracy of the wake-up control of the second cell.

[0124] Optionally, the first event can include but is not limited to at least one of the following:

[0125] At least one event of all events of the RRC idle state terminal initiating the random access procedure except the second event;

[0143] It should be noted that the first event of the present embodiment can refer to the related description of the preceding embodiments, which will not be repeated here.

[0144] In the present embodiment, by carrying at least one of the second information and the third information in the first configuration information or the first message, signaling overhead can be saved.

[0145] Optionally, the second information comprises at least one of:

[0146] at least one PLMN information;

[0147] first indication information, used for indicating whether the first configuration information is applicable to each PLMN in a PLMN-IdentityInfoList in a system information block (SIB1) of the first cell.

[0148] Exemplarily, the PLMN information can comprise, but is not limited to, a PLMN identity, etc.

[0149] Exemplarily, whether the first configuration information is applicable to each PLMN in the PLMN-IdentityInfoList can be indicated by a bitmap, each bit of the bitmap is associated with each PLMN in the PLMN-IdentityInfoList, if the bit associated with a certain PLMN in the PLMN-IdentityInfoList is 1, it indicates that the first configuration information is applicable to the PLMN, if the bit associated with a certain PLMN in the PLMN-IdentityInfoList is 0, it indicates that the first configuration information is not applicable to the PLMN; or, if the bit associated with a certain PLMN in the PLMN-IdentityInfoList is 0, it indicates that the first configuration information is applicable to the PLMN, if the bit associated with a certain PLMN in the PLMN-IdentityInfoList is 1, it indicates that the first configuration information is not applicable to the PLMN.

[0150] In this embodiment, by directly configuring at least one PLMN information, the terminal can accurately and quickly learn the PLMN to which the first configuration information is applicable; by using the first indication information to indicate whether the first configuration information is applicable to each PLMN in the PLMN-IdentityInfoList in the SIB1 of the first cell, resource overhead can be saved.

[0151] Optionally, the method further comprises:

[0152] in a case where a first condition is met, the terminal sends fourth information to a third cell;

[0153] wherein the third cell is a cell in the second cell, and the fourth information is used for requesting or indicating the third cell in the first state to change to a second state;

[0154] The first condition comprises at least one of:

[0155] The third cell does not send the first information.

[0156] The terminal does not exist the first event.

[0157] The terminal exists the first event.

[0158] The first cell satisfies a first sub-condition.

[0159] The third cell satisfies a second sub-condition.

[0160] A cellBarred field in a master information block (MIB) of the third cell is set to notBarred.

[0161] In a case where the terminal does not support network energy saving cell discontinuous transmission and discontinuous reception (nes-CellDTX-DRX), the cellBarred field in the MIB of the third cell is set to notBarred.

[0162] The first sub-condition includes at least one of the following:

[0163] The first cell is not a suitable cell.

[0164] A signal quality of the first cell is less than or equal to a first threshold.

[0165] The second sub-condition includes:

[0166] A signal quality of the third cell is greater than or equal to a second threshold.

[0167] The first threshold and the second threshold can be predefined by a protocol or configured by a network side device. The signal quality can include at least one of Reference Signal Receiving Power (RSRP), Reference Signal Received Quality (RSRQ), and Signal to Interference Plus Noise Ratio (SINR).

[0168] The suitable cell can be a suitable cell defined in cell selection and reselection of related technologies, for example, a UE satisfying S criteria, not barred, and a PLMN of the cell meeting requirements.

[0169] In the embodiment, in the case that the number of cells included in the second cell is one, the third cell is the second cell, and in the case that the number of cells included in the second cell is at least two, the third cell can include at least one cell in the second cell.

[0170] Specifically, in the case that the first condition is met, the terminal can send the fourth information to the third cell according to the first configuration information to request or instruct the third cell in the first state to transition to the second state. For example, whether the first condition is met can be determined by the RRC layer of the terminal, and in the case that the first condition is met, the fourth information is sent to the third cell according to the first configuration information.

[0171] Exemplarily, the fourth information can include a preamble. For example, in the case that the first condition is met, the terminal can send the preamble to the third cell through Msg1 or MsgA, and the preamble is used to request or instruct the third cell in the first state to transition to the second state.

[0172] In some embodiments, the fourth information can also be referred to as UL WUS.

[0173] The embodiment will be described below in conjunction with examples:

[0174] Example 1: In the case that the third cell does not send the first information, the terminal sends the fourth information to the third cell. In this example, the value of the cellBarred field and whether the terminal supports nes-CellDTX-DRX can not be considered.

[0175] Example 2: In the case that the third cell does not send the first information and the cellBarred field of the MIB of the third cell is set to notBarred, the terminal sends the fourth information to the third cell. In this example, whether the terminal supports nes-CellDTX-DRX can not be considered, that is, regardless of whether the terminal supports nes-CellDTX-DRX, as long as the third cell does not send the first information and the cellBarred field of the MIB of the third cell is set to notBarred, the terminal sends the fourth information to the third cell.

[0176] Example 3: In the case that the third cell does not send the first information, and in the case that the terminal does not support nes-CellDTX-DRX, and in the case that the cellBarred field of the MIB of the third cell is set to notBarred, the terminal sends the fourth information to the third cell. Alternatively, if the terminal supports nes-CellDTX-DRX, the terminal can send the fourth information to the third cell in the case that the third cell does not send the first information, regardless of whether the cellBarred field of the MIB of the third cell is set to notBarred.

[0177] Example 4: In the case that the cellBarred field of the MIB of the third cell is set to notBarred, the terminal sends the fourth information to the third cell. In this example, whether the third cell sends the first information and whether the terminal supports nes-CellDTX-DRX can not be considered.

[0178] Example 5: In the case that the terminal does not support nes-CellDTX-DRX, if the cellBarred field of the MIB of the third cell is set to notBarred, the terminal sends the fourth information to the third cell. In this example, whether the third cell sends the first information can not be considered. Alternatively, if the terminal supports nes-CellDTX-DRX, the terminal can send the fourth information to the third cell regardless of whether the cellBarred field of the MIB of the third cell is set to notBarred.

[0179] The embodiment enables the terminal to send the fourth information to the third cell in the case that the first condition is met, which is advantageous to improve the accuracy of the wake-up control of the third cell, reduce some unnecessary fourth information sending, and save resources.

[0180] Alternatively, in the case that the first condition is met, the terminal sending the fourth information to the third cell comprises at least one of the following:

[0181] If the terminal has the first event, in the case that the first condition is met, the terminal sends the fourth information to the third cell.

[0182] If the terminal does not have the first event, in the case that the first condition is met, the terminal sends the fourth information to the third cell.

[0183] In an embodiment, if the terminal has the first event, in the case that the first condition is met, the terminal sends the fourth information to the third cell, i.e., the RACH procedure for requesting the first information of the third cell is preferentially performed, which can ensure the acquisition of the first information.

[0184] In the embodiment, optionally, if the terminal does not have the first event, the terminal can or can not send the fourth information to the third cell when the first condition is met.

[0185] In another embodiment, if the terminal does not have the first event, the terminal sends the fourth information to the third cell when the first condition is met; if the terminal has the first event, the terminal can not send the fourth information to the third cell when the first condition is met, thereby giving priority to the execution of the process corresponding to the first event, for example, when the first event is emergency service or emergency call, the emergency service / call is very sensitive to delay, and the sending of the fourth information will interrupt the process of the emergency service / call, thereby affecting the emergency service / call, and thus the emergency service / call needs to be given priority.

[0186] Optionally, if the terminal has the first event, the terminal sends the fourth information to the third cell when the first condition is met and the third cell supports the first event, comprising:

[0187] If the terminal has the first event, the terminal sends the fourth information to the third cell when the first condition is met and the third cell supports the first event.

[0188] In the embodiment, if the terminal has the first event, the terminal sends the fourth information to the third cell when the first condition is met and the third cell supports the first event, which is beneficial to avoid the failure of the execution of the RACH process corresponding to the first event due to the fact that the third cell does not support the first event.

[0189] In some optional embodiments, if the third cell does not support the first event, the terminal can not send the fourth information to the third cell when the terminal has the first event and the first condition is met.

[0190] Optionally, if the terminal does not have the first event, the terminal sends the fourth information to the third cell when the first condition is met, comprising at least one of the following:

[0191] If the terminal does not have the first event, the terminal sends the fourth information to the third cell when the first condition is met and the third cell supports the first event.

[0192] If the terminal does not have the first event, the terminal sends the fourth information to the third cell when the first condition is met and the third cell does not support the first event.

[0193] In an embodiment, if the terminal does not have the first event, the terminal sends the fourth information to the third cell when the first condition is met and the third cell supports the first event, which is beneficial to ensure the execution of the process corresponding to the first event, for example, when the first event is emergency service or emergency call, the emergency service / call is sensitive to delay, the sending of the fourth information will interrupt the flow of the emergency service / call and thus affect the emergency service / call, and thus the emergency service / call needs to be ensured.

[0194] In this embodiment, optionally, if the terminal does not have the first event, the terminal can or can not send the fourth information to the third cell when the first condition is met and the third cell does not support the first event.

[0195] In another embodiment, if the terminal does not have the first event, the terminal sends the fourth information to the third cell when the first condition is met and the third cell does not support the first event, which can reduce the occurrence of the interruption of the process of obtaining the first information of the third cell by the first event of the terminal.

[0196] In this embodiment, optionally, if the terminal does not have the first event, the terminal can or can not send the fourth information to the third cell when the first condition is met and the third cell supports the first event.

[0197] Optionally, before the terminal sends the fourth information to the third cell when the first condition is met, the method further comprises:

[0198] When the second RACH process is triggered in the case that the first RACH process for requesting the first information of the third cell is ongoing in the MAC layer of the terminal, the MAC layer of the terminal performs a first behavior;

[0199] The first RACH process is a RACH process for the first event, and the second RACH process is a RACH process for requesting the first information of the third cell; or the first RACH process is a RACH process for requesting the first information of the third cell, and the second RACH process is a RACH process for the first event.

[0200] The first behavior includes at least one of the following:

[0201] selecting a RACH process for the first event;

[0202] selecting a RACH process for requesting the first information of the third cell;

[0203] If the first cell satisfies the first sub-condition and / or the third cell satisfies the second sub-condition, a RACH procedure for requesting the first information of the third cell is selected, otherwise a RACH procedure for the first event is selected.

[0204] In an embodiment, in the case that the RACH procedure for requesting the first information of the third cell and the RACH procedure for the first event are both triggered, the MAC layer of the terminal can select the RACH procedure for the first event, so as to give priority to the execution of the RACH procedure for the first event.

[0205] It should be noted that if the RACH procedure for the first event is the first RACH procedure, this embodiment means that the terminal continues the RACH procedure for the first event; if the RACH procedure for the first event is the second RACH procedure, this embodiment means that the terminal starts the RACH procedure for the first event.

[0206] In another embodiment, in the case that the RACH procedure for requesting the first information of the third cell and the RACH procedure for the first event are both triggered, the MAC layer of the terminal can select the RACH procedure for requesting the first information of the third cell, so as to give priority to the acquisition of the first information of the third cell.

[0207] It should be noted that if the RACH procedure for requesting the first information of the third cell is the first RACH procedure, this embodiment means that the terminal continues the RACH procedure for requesting the first information of the third cell; if the RACH procedure for requesting the first information of the third cell is the second RACH procedure, this embodiment means that the terminal starts the RACH procedure for requesting the first information of the third cell.

[0208] In yet another embodiment, in the case that the RACH procedure for requesting the first information of the third cell and the RACH procedure for the first event are both triggered, if the first cell satisfies the first sub-condition and / or the third cell satisfies the second sub-condition, the MAC layer of the terminal selects the RACH procedure for requesting the first information of the third cell, so as to give priority to the acquisition of the first information of the third cell; otherwise, the RACH procedure for the first event is selected, so as to give priority to the execution of the RACH procedure for the first event.

[0209] It should be noted that the above description of selection is only an example, and the present embodiment does not limit the word "selection" to this example, as long as the word can express the following meanings:

[0210] The selecting the RACH procedure for the first event can refer to: if the RACH procedure for the first event is the first RACH procedure, the selecting refers to the terminal continuing the RACH procedure for the first event; if the RACH procedure for the first event is the second RACH procedure, the selecting refers to the terminal starting the RACH procedure for the first event.

[0211] The selecting the RACH procedure for requesting the first information of the third cell can refer to: if the RACH procedure for requesting the first information of the third cell is the first RACH procedure, the selecting refers to the terminal continuing the RACH procedure for requesting the first information of the third cell; if the RACH procedure for requesting the first information of the third cell is the second RACH procedure, the selecting refers to the terminal starting the RACH procedure for requesting the first information of the third cell.

[0212] Optionally, the method further comprises:

[0216] Cell identification information for identifying the cell that needs to transition from the first state to the second state;

[0217] Preamble information;

[0218] Fourth indication information for indicating the beam of the cell sending the first information.

[0219] The third indication information for indicating whether the cell agrees to transition from the first state to the second state can be indicated by one bit, for example, where 1 means agreement and 0 means disagreement, or 1 means disagreement and 0 means agreement.

[0220] The cell identification information can be at least one of a carrier and a physical cell identifier (PCI).

[0221] The fifth information can be carried in a random access response (RAR), for example, the third cell sends Msg2 or MsgB to the terminal, the Msg2 or MsgB carries the RAR, and the RAR carries the fifth information.

[0222] Optionally, the terminal sends fourth information to the third cell, comprising:

[0223] In a case that the terminal receives the short message sent by the first cell and the terminal has not determined whether the first configuration information changes, the terminal postpones sending the fourth information until it is determined that the first configuration information does not change, or the terminal postpones sending the fourth information until the latest first configuration information is acquired in a case that it is determined that the first configuration information changes.

[0224] and / or,

[0225] In a case that the terminal has sent the fourth information to the third cell, the method further comprises:

[0226] In a case that the terminal receives the short message sent by the first cell and the terminal has not determined whether the first configuration information changes, the terminal performs at least one of the following:

[0227] suspending at least one of receiving the fifth information and sending the fourth information until the terminal determines that the first configuration information does not change;

[0228] suspending a random access channel (RACH) procedure related to the fourth information until the terminal determines that the first configuration information does not change.

[0229] Exemplarily, the short message can be a short message in which a systemInfoModification field or a systemInfoModification-eDRX field is set to 1.

[0230] In the embodiment, in a case that the terminal receives the short message sent by the first cell and the terminal has not determined whether the first configuration information changes, the terminal postpones sending the fourth information until it is determined that the first configuration information does not change, or the terminal postpones sending the fourth information until the latest first configuration information is acquired in a case that it is determined that the first configuration information changes, so as to facilitate ensuring that the fourth information is sent based on the valid first configuration information.

[0231] In a case that the terminal has sent the fourth information to the third cell, if the terminal receives the short message sent by the first cell and the terminal has not determined whether the first configuration information changes, the terminal suspends at least one of receiving the fifth information and sending the fourth information until the terminal determines that the first configuration information does not change, or suspends a RACH procedure related to the fourth information until the terminal determines that the first configuration information does not change, so as to facilitate ensuring that at least one of receiving the fifth information and sending the fourth information is based on the valid first configuration information.

[0232] Optionally, the method further comprises:

[0233] terminating at least one of the receiving of the fifth information and the transmitting of the fourth information upon determining that the first configuration information has changed, or terminating the RACH procedure related to the fourth information upon determining that the first configuration information has changed.

[0234] In the embodiment, at least one of the receiving of the fifth information and the transmitting of the fourth information is terminated upon determining that the first configuration information has changed, or the RACH procedure related to the fourth information is terminated upon determining that the first configuration information has changed, so that the waste of resources caused by some invalid operations can be reduced.

[0235] In some optional embodiments, when the first configuration information is applicable to multiple cells, which cell or which cells need to be changed from the first state to the second state and which cell or which cells need to transmit the fifth information can be determined by coordination among the multiple cells.

[0236] For example, the first indicator value of each cell receiving the fourth information can be ranked in descending order, and the first T cells need to be changed from the first state to the second state, wherein the first indicator value can include but is not limited to at least one of the power, quality and SINR of receiving the fourth information, and T is a positive integer.

[0237] For example, the cell that needs to transmit the fifth information can include one of the following:

[0238] all the cells that need to be changed from the first state to the second state;

[0239] one cell selected from all the cells that need to be changed from the first state to the second state;

[0240] one cell selected from all the cells to which the first configuration information is applicable.

[0241] Optionally, the method further comprises:

[0242] The terminal receives the first information of the third cell.

[0243] For example, the first information can include but is not limited to SIB1 (e.g., on demand SIB1), SSB (e.g., on demand SSB), etc.

[0244] For example, in the case where the third cell includes multiple cells, the terminal can receive the first information of part or all of the cells of the third cell.

[0245] Optionally, the method further comprises at least one of the following:

[0246] the terminal considers that the first information is to be transmitted on at least one physical downlink shared channel (PDCCH) occasion of the first SSB;

[0247] the terminal considers that the first information is to be transmitted on the first SSB;

[0248] the terminal considers that the first information is to be transmitted on a beam indicated by the fourth indication information;

[0249] the terminal considers that the first information is to be transmitted on a beam corresponding to beam information of the first configuration information;

[0250] the terminal considers that the first information is to be transmitted on a beam corresponding to the fourth information;

[0251] the terminal considers that the first information is to be transmitted on all SSBs of the third cell;

[0252] wherein the first SSBs include all SSBs determined by a ssb-PositionsInBurst parameter of the first SSB of the third cell in a burst, or the first SSBs include all SSBs determined by a preamble in the first configuration information.

[0253] It should be noted that the fourth indication information, the first configuration information, and the fourth information of the present embodiment can refer to the related descriptions of the foregoing embodiments, which will not be repeated here. In addition, each preamble corresponds to an SSB, so the SSBs can be obtained through the preambles in the first configuration information.

[0254] In some optional embodiments, how the terminal selects an SSB or a beam to receive the first information can depend on the terminal implementation.

[0255] For example, in the case where the number of SSBs of the first SSB is 1, the terminal can receive the first information on the first SSB; in the case where the number of SSBs of the first SSB is greater than 1, how the terminal selects an SSB to receive the first information can depend on the UE implementation, for example, the terminal can receive the first information on each SSB of the first SSB, or the terminal can receive the first information on part of the SSBs selected from the first SSB.

[0256] In a case where the number of beams indicated by the fourth indication information is 1, the terminal can receive the first information on the beam indicated by the fourth indication information; in a case where the number of beams indicated by the fourth indication information is greater than 1, how the terminal selects beams to receive the first information can depend on UE implementation, for example, the terminal can receive the first information on each of the beams indicated by the fourth indication information, or the terminal can receive the first information on part of the beams selected from the beams indicated by the fourth indication information.

[0257] In a case where the number of beams corresponding to the beam information of the first configuration information is 1, the terminal can receive the first information on the beam corresponding to the beam information of the first configuration information; in a case where the number of beams corresponding to the beam information of the first configuration information is greater than 1, how the terminal selects beams to receive the first information can depend on UE implementation, for example, the terminal can receive the first information on each of the beams corresponding to the beam information of the first configuration information, or the terminal can receive the first information on part of the beams selected from the beams corresponding to the beam information of the first configuration information.

[0258] In a case where the number of beams corresponding to the fourth information is 1, the terminal can receive the first information on the beam corresponding to the fourth information; in a case where the number of beams corresponding to the fourth information is greater than 1, how the terminal selects beams to receive the first information can depend on UE implementation, for example, the terminal can receive the first information on each of the beams corresponding to the fourth information, or the terminal can receive the first information on part of the beams selected from the beams corresponding to the fourth information.

[0259] It can be understood that the number of all SSBs of the third cell is usually greater than 1, and therefore how the terminal selects SSBs from all SSBs of the third cell to receive the first information can depend on UE implementation, for example, the terminal can receive the first information on each of the SSBs of the third cell, or the terminal can receive the first information on part of the SSBs selected from all SSBs of the third cell.

[0260] It should also be noted that a beam usually corresponds to an SSB, and therefore selecting a beam to receive the first information can also be referred to as selecting an SSB to receive the first information.

[0261] Optionally, the terminal receives the first information of the third cell, including at least one of the following:

[0262] In a case where the number of SSBs in the first SSB is greater than or equal to 2, the terminal receives the first information on the SSB selected from the first SSB;

[0263] In a case where the number of beams indicated by the fourth indication information is greater than or equal to 2, the terminal receives the first information from a beam selected from the beams indicated by the fourth indication information;

[0264] In a case where the number of beams corresponding to the beam information of the first configuration information is greater than or equal to 2, the terminal receives the first information from a beam selected from the beams corresponding to the beam information of the first configuration information;

[0265] The terminal receives the first information on a SSB selected from all SSBs of the third cell;

[0266] The terminal receives the first information on a beam corresponding to the fourth information.

[0267] In the embodiment, how the terminal selects the SSB and how the terminal selects the beam can depend on implementation of the terminal.

[0268] Optionally, the method further includes:

[0269] In a case where it is determined according to the first information of the third cell that the third cell is a suitable cell, the terminal camps on the third cell.

[0270] Optionally, after the terminal camps on the third cell, the method further includes:

[0271] In a case where a second condition is met, the terminal receives the first information of the third cell;

[0272] The second condition includes at least one of the following:

[0274] Receiving a short message sent by the third cell, and an earthquake and tsunami warning system and commercial mobile alert service indication (etwsAndCmasIndication) field of the short message is set to a second value.

[0275] Exemplarily, the first value and the second value can both be 1.

[0276] In the embodiment, in a case that the terminal receives the short message sent by the third cell and the systemInfoModification field or the systemInfoModification-eDRX field of the short message is set to the first value, it is indicated that the system information is modified, and therefore the terminal can receive the first information of the third cell to obtain the updated system information.

[0277] In a case that the terminal receives the short message sent by the third cell and the etwsAndCmasIndication field of the short message is set to the second value, it is indicated that the early warning notification exists, and therefore the terminal can receive the first information of the third cell to obtain the corresponding notification.

[0283] The second SSB comprises all SSBs determined by a second ssb-PositionsInBurst parameter of the third cell.

[0284] The second condition comprises at least one of the following:

[0285] Receiving the short message sent by the third cell and the systemInfoModification field or the systemInfoModification-eDRX field of the short message is set to the first value;

[0286] Receiving the short message sent by the third cell and the etwsAndCmasIndication field of the short message is set to the second value.

[0287] In some optional embodiments, after the terminal camps on the third cell, how the terminal selects the SSB to receive the first information can depend on the implementation of the terminal.

[0288] Exemplarily, in a case where the number of SSBs of the second SSB is 1, the terminal receives the first information on the second SSB; in a case where the number of SSBs of the second SSB is greater than 1, the terminal can receive the first information on each SSB of the second SSB, or the terminal can receive the first information on part of SSBs selected from the second SSB. Alternatively, the terminal can receive the first information on each SSB of the third cell, or the terminal can receive the first information on part of SSBs selected from all SSBs of the third cell.

[0289] Optionally, the receiving, by the terminal, the first information of the third cell in the case where the second condition is met, comprises at least one of:

[0290] In the case where the second condition is met, if the number of SSBs in the second SSB is greater than or equal to 2, the terminal receives the first information on SSBs selected from the second SSB;

[0291] In the case where the second condition is met, the terminal receives the first information on SSBs selected from all SSBs of the third cell.

[0292] In the embodiment, how the terminal selects SSBs to send the first information can depend on implementation of the terminal.

[0293] Optionally, the receiving, by the terminal, the first information of the third cell in the case where the second condition is met, comprises:

[0294] In the case where the second condition is met, the terminal starts receiving the first information of the third cell from a first time point, until receiving the first information of the third cell at or before a second time point or reaching the second time point;

[0295] The first time point comprises one of:

[0296] a start position of a next modification period;

[0297] a start position of a next eDRX acquisition period boundary;

[0298] a time point at which the terminal receives a short message;

[0299] and / or,

[0306] The time point when the terminal receives the short message, for example, the time point when the terminal receives the short message with etwsAndCmasIndication field set to 1.

[0307] For the start position of the next modification period being offset by X first information periods, for example, if the start position of the next modification period is t1 and the first information period is T, the start position of the next modification period being offset by X first information periods can be t1+X*T.

[0308] For the start position of the next eDRX acquisition cycle boundary being offset by Y first information periods, for example, if the start position of the next eDRX acquisition cycle boundary is t2 and the first information period is T, the start position of the next eDRX acquisition cycle boundary being offset by Y first information periods can be t2+Y*T.

[0309] For the time point when the terminal receives the short message being offset by Z first information periods, for example, if the time point when the terminal receives the short message is t3 and the first information period is T, the time point when the terminal receives the short message being offset by Z first information periods can be t3+Z*T.

[0310] Specifically, in the case of satisfying the second condition, the terminal starts receiving the first information of the third cell from the first time point, and once the first information of the third cell is received before the second time point, the receiving of the first information of the third cell can be ended, and if the first information of the third cell is not received until the second time point is reached, the receiving of the first information of the third cell is also ended.

[0311] Optionally, in the case that the terminal camps on the third cell, the method further comprises:

[0312] the terminal acquires second configuration information from the third cell;

[0313] The second configuration information comprises at least one of the following:

[0314] The third configuration information is used for the terminal to request or indicate the third cell in the first state to transit to the second state.

[0315] The fourth configuration information is used for the terminal to request or indicate a fourth cell in the first state to transit to the second state, and the fourth cell is different from the third cell.

[0316] The fourth cell can be any cell different from the third cell. For example, the fourth cell can be a neighboring cell of the third cell.

[0317] For example, the third configuration information can include beam information used for receiving the first information, or the third configuration information includes the beam information used for receiving the first information and a validity time of the third configuration information. The fourth configuration information can include beam information used for receiving the first information, or the fourth configuration information includes the beam information used for receiving the first information and a validity time of the fourth configuration information.

[0318] In some embodiments, after the cell transits from the first state to the second state and transmits the first information, the cell can automatically transit to the first state. Thus, if the terminal needs the first information of the cell again, the terminal needs to request or indicate the cell to transit from the first state to the second state again. Therefore, when the terminal camps on the third cell, the third cell can transmit the third configuration information to the terminal. Thus, if the terminal needs the first information of the third cell again, the terminal can request or indicate the third cell to transit from the first state to the second state again based on the third configuration information. Since the third configuration information is obtained from the third cell when the terminal camps on the third cell, the convenience of obtaining the configuration information used for requesting or indicating the third cell to transit from the first state to the second state is improved.

[0319] In some embodiments, when the terminal camps on the third cell, the fourth configuration information used for indicating or requesting a neighboring cell (i.e., the fourth cell) of the third cell to transit from the first state to the second state can be obtained from the third cell. Thus, the convenience of obtaining the configuration information used for requesting or indicating the neighboring cell of the third cell to transit from the first state to the second state is improved.

[0320] Optionally, when the second configuration information includes the third configuration information, the method further includes:

[0321] When the third condition is met, the terminal transmits fourth information to the third cell.

[0322] The third condition includes at least one of the following:

[0324] The terminal receives a short message sent by the third cell, and the short message indicates that the resource for requesting the third cell to send the OSI message has changed;

[0325] The terminal does not receive the first information sent by the third cell after receiving the short message sent by the third cell;

[0326] The terminal has valid third configuration information.

[0327] For the short message indicating that the resource for requesting the third cell to send the OSI message has changed, for example, SI-RequestConfig, SI-RequestConfigRepetition, SI-RequestResources, si-RequestResourcesRepetitionNum2, SI-RequestConfigRepetitionNum4, SI-RequestConfigRepetitionNum8, etc. have changed.

[0328] For the terminal not receiving the first information sent by the third cell after receiving the short message sent by the third cell, for example, the terminal receives a short message sent by the third cell, and the systemInfoModification field or the systemInfoModification-eDRX field or the etwsAndCmasIndication field of the short message is set to 1. After receiving the short message, the terminal does not receive the first information sent by the third cell.

[0329] It should be further pointed out that in the embodiment, the terminal can send the fourth information to the third cell based on the third configuration information.

[0330] Optionally, in the case where the second configuration information includes the fourth configuration information, the method further includes:

[0336] Optionally, the terminal receives second configuration information from the third cell, including one of:

[0337] The terminal acquires the second configuration information from the third cell when the terminal camps on the third cell;

[0338] The terminal acquires the second configuration information from the third cell when the terminal determines that the third cell is transmitting the first information after the terminal camps on the third cell.

[0339] Exemplarily, the terminal acquires the second configuration information as soon as the terminal camps on the third cell; or the terminal determines whether the third cell is transmitting the first information after the terminal camps on the third cell, such as determining whether the indication of the first message transmitted by the third cell is being transmitted, if yes, the terminal acquires the second configuration information immediately, otherwise, the terminal does not acquire the second configuration information, but continues to use the first configuration information applicable to the third cell which has been acquired in the first cell.

[0340] Optionally, the method further comprises:

[0341] The terminal considers the first configuration information valid when the terminal determines that the third cell is not transmitting the first information.

[0342] In this embodiment, the terminal considers the first configuration information valid, that is, the terminal still uses the first configuration information to request or instruct the third cell to change from the first state to the second state.

[0343] Optionally, the terminal receiving the first message of the first cell includes at least one of:

[0344] The terminal camps on the first cell;

[0354] determining whether to perform cell reselection related evaluation on the fifth cell or determining whether to perform acquisition of the SIB1 related to cell reselection on the fifth cell;

[0355] The fifth cell includes a cell whose transmission of the first information needs to be requested by the terminal or a cell whose first information is not transmitted.

[0356] Exemplarily, in a case where the terminal camps on the first cell or the third cell, in an RRC connection establishment or RRC connection recovery process, for example, in a terminal behavior process of transmitting an RRCResumeRequest or RRCResumeRequest1 or RRCSetup message, if the terminal is a terminal with an on-demand request first information capability, the terminal does not perform cell reselection related measurement and evaluation on the fifth cell, or the terminal does not necessarily perform cell reselection related measurement and evaluation on the fifth cell, that is, the terminal can decide whether to perform cell reselection related measurement and evaluation on the fifth cell, so that the occurrence of the case that the first information acquisition process of the fifth information is interrupted can be reduced.
