The base station is not limited to a specific technical term, and it should be noted that only a base station in an NR system is taken as an example for description in the embodiments of the present application, and the specific type of the base station is not limited.

[0102] The related prior art of the present application is briefly described as follows.

[0103] System information of a cell is periodically broadcasted, including Master Information Block (MIB) and a series of System Information Blocks (SIBs). MIB is carried in a MIB message on Broadcast Channel (BCH) and is periodically broadcasted with a fixed period of 80 ms. The MIB message contains cell barring information and physical layer information necessary for acquiring further system information. The series of System Information Blocks includes SIB1 and other SIBs (SIB2, SIB3,...). Among them, SIB1 is periodically broadcasted with a fixed period of 160 ms in a SIB1 message, which defines the scheduling of other SIBs and contains messages required for initial access.

[0104] Other SIBs are periodically broadcasted in System Information (SI) messages with configured periods. In SIB1, scheduling information of one or more SI messages can be configured, including the period of each SI message and one or more SIBs mapped thereon, that is, these SIBs with the same period are mapped into this SI message for transmission. Different SI messages can have different periods or the same period, depending on the scheduling configuration in SIB1. The UE acquires the SIBs carried in the corresponding SI message after reading the SI message.

[0105] The period of an SI message is calculated from the starting boundary of frame 0. From the perspective of time domain, each SI message starts from the start of the period of the SI message and occupies a transmission window for transmission. The length of the transmission window is configured in SIB1 (i.e., si-WindowLength information element), and all SI messages have the same transmission window length. Each transmission window can only transmit the same SI message, that is, the transmission of SI messages is serial. When the starting boundaries of the periods of multiple SI messages are the same (for example, from frame 0, all SI messages need to be transmitted), the SI messages are transmitted according to the order of their appearance in the scheduling information (schedulingInfoList) of SIB1, that is, the one appearing earlier is transmitted first.

[0106] For example: assuming that the length of the transmission window of the cell is s20, i.e., 20 slots, and the subcarrier spacing of the cell is 30 kHz, then one transmission window occupies 1 radio frame (10 ms). Assuming that the scheduling information configured in SIB1 and the order of the SI messages in the scheduling information are as shown in Table 1.

[0107] Table 1: One of the tables of scheduling information of SIB1 configuration and the order of each SI message in the scheduling information

[0108] Order in scheduling information SI number Period (radio frame) 1 SI-1 8 2 SI-2 8 3 SI-3 16 4 SI-4 16 5 SI-5 32 6 SI-6 32 7 SI-7 32

[0109] The sending of each SI message is shown in Figure 2 . The network needs to ensure that the ordered sending of SI messages cannot exceed the start position of the next period of the SI message with the shortest period, otherwise a conflict will occur. Therefore, the maximum number of SI messages that can be configured depends on the shortest period of the configured SI messages and the length of the sending window, i.e., (the maximum number of SI messages that can be configured) = (the shortest period of the configured SI messages) divided by (the length of the sending window). If in the above example, SI8-SI11 also need to be sent, as shown in Table 2:

[0110] Table 2: Another table of scheduling information of SIB1 configuration and the order of each SI message in the scheduling information

[0111]

[0112]

[0113] According to the existing SI message sending mechanism, the sending window of SI-9, SI-10, and SI-11 exceeds the range of the shortest period and overlaps with the sending window of the next period of SI-1 and SI-2 with a period of 8 radio frames, resulting in a conflict, as shown in Figure 3 . Although there are still some idle resources (marked as empty sending windows).

[0114] With the evolution of the standard protocol, more SIBs may need to be introduced, and more SI messages will also be needed, such as a large number of SI messages for positioning features. However, the existing mechanism described above may not be able to support future needs.

[0115] The system information transmission method, device, terminal, and access network device provided by the embodiments of the present application will be described in detail below in combination with the accompanying drawings and some embodiments and their application scenarios.

[0116] As shown in Figure 4 , the present application provides a system information transmission method, comprising:

[0117] Step 401: The terminal receives the scheduling information list sent by the access network device;

[0118] It should be noted that the scheduling information list at least includes the scheduling information of a first system information (SI) message, and the scheduling information of the first SI message includes the sending period corresponding to the first SI message.

[0119] It should be noted that the scheduling information list in the embodiments of the present application is different from the schedulingInfoList in the existing SIB1, that is, the schedulingInfoList in the existing SIB1 is a table, and the scheduling information list in the embodiments of the present application is another table different from the schedulingInfoList in the existing SIB1 in the SIB1. That is, the SI message in the schedulingInfoList in the existing SIB1 adopts a transmission rule, and the SI message in the scheduling information list in the embodiments of the present application adopts another new transmission rule.

[0120] The first SI message in the embodiments of the present application refers to any one SI message in the scheduling information list that needs to be received by the terminal.

[0121] In step 402, the terminal determines the transmission window of the first SI message according to a first rule.

[0122] It should be noted that the first rule includes the following one:

[0123] A11, according to the sorting position of the first SI message in the scheduling information list and the transmission period corresponding to the first SI message, the transmission window of the first SI message is determined in the transmission period corresponding to the first SI message in the direction from the tail to the head.

[0124] It should be noted that this way is considered to take into account the idle transmission window at the tail of each transmission period, in order to utilize these idle transmission windows, the transmission window is determined in the direction from the tail to the head of the transmission period, which can effectively utilize the idle transmission window and avoid the conflict of SI messages as much as possible, so that the access network device can transmit more SI messages.

[0125] A12, according to the transmission window indicated by the access network device, the transmission window of the first SI message is determined.

[0126] It should be noted that this way can avoid the conflict of SI messages by indicating the transmission window, so that the transmission window falls in the idle transmission window, so that the access network device can transmit more SI messages.

[0127] A13, according to the sorting position of the first SI message in the scheduling information list and the transmission period corresponding to the first SI message, the transmission window of the first SI message is determined in the transmission period corresponding to the first SI message in the direction from the head to the tail by skipping the conflict SI message.

[0128] It should be noted that the sending window is determined by skipping the conflict, the idle sending window can be fully utilized, the conflict of the SI message can be effectively avoided, the access network device can transmit more SI messages, and accurate transmission of the SI message can be further ensured.

[0129] In step 403, the terminal receives the first SI message in the sending window.

[0130] It should be noted that the SI message sending window is determined by effectively utilizing the idle sending window, and the requirement of transmitting more SI messages can be met.

[0131] Optionally, an implementation manner of the A11 can be adopted as follows:

[0132] According to the order of the SI messages in the scheduling information list or the reverse order, the sending window of the first SI message is determined in the sending period corresponding to the first SI message in a direction from the first position to the head of the list according to the sorting position of the first SI message in the scheduling information list and the sending period corresponding to the first SI message.

[0133] The first position is the last sending window at the tail of the sending period corresponding to the first SI message, or the first position is the last sending window at the tail of the sending period corresponding to the first SI message minus a sending window offset value.

[0134] It should be noted that the specific implementation manner of determining the sending window of the first SI message is as follows:

[0135] When the first SI message is the a-th SI message in the scheduling information list in the order or the reverse order, the sending window of the first SI message is determined as the a-th sending window in the direction from the first position to the head of the list in the sending period corresponding to the first SI message.

[0136] The a is a positive integer.

[0137] For example, when the order is adopted and the offset value of the sending window is not considered, if the first SI message is the first SI message in the scheduling information list, the sending window of the first SI message is the last sending window in the sending period corresponding to the first SI message; when the order is adopted and the offset value of the sending window is considered (the offset value is 2, that is, two sending windows are offset), if the first SI message is the first SI message in the scheduling information list, the sending window of the first SI message is the third sending window from the end in the sending period corresponding to the first SI message.

[0138] For example, when the reverse order is adopted and the offset value of the transmission window is not considered, if the first SI message is the second last SI message in the scheduling information list, the transmission window of the first SI message is the second last transmission window in the transmission period corresponding to the first SI message; when the reverse order is adopted and the offset value of the transmission window is considered (at this time, the offset value is 2, i.e., offset by two transmission windows), if the first SI message is the second last SI message in the scheduling information list, the transmission window of the first SI message is the fourth last transmission window in the transmission period corresponding to the first SI message.

[0139] Optionally, it also needs to be explained that in the case where the first position is the last transmission window at the tail of the transmission period corresponding to the first SI message minus the offset value of the transmission window, the method further comprises:

[0140] The terminal receives the offset value of the transmission window sent by the access network device.

[0141] That is, in this case, the access network device will inform the terminal of the offset value of the transmission window, and generally, the offset value can be sent to the terminal together with the scheduling information list in SIB1.

[0142] Specific application case one,

[0143] Considering that the idle transmission windows are at the tail of each period, in order to utilize these idle transmission windows, for some SI messages, it can be configured to determine the transmission window from the tail to the head of the period of the SI message. A new scheduling information list, such as a schedulingInfoList2 information element (the name is only an example, and is not limited in the embodiments of the present application), is newly introduced, and the SI messages configured in the scheduling information list adopt the new mechanism. Specifically, according to the ordering position of a certain SI message in the schedulingInfoList2, the transmission window is determined from the tail to the head of the transmission period corresponding to the SI message, for example, if the SI message is the first one, the SI message is sent in the first transmission window from the tail to the head of the transmission period corresponding to the SI message, if the SI message is the second one, the SI message is sent in the second transmission window from the tail to the head of the transmission period corresponding to the SI message, and so on. It needs to be explained here that the SI messages configured in the existing schedulingInfoList information element still use the existing mechanism.

[0144] Optionally, considering backward compatibility, these SI messages using the new mechanism (i.e. configured in schedulingInfoList2) exclude the SIBs defined in the current standard, such as SIB2-SIB14, which use the original mechanism, i.e. the subsequently introduced SIBs can be mapped to these SI messages for transmission. Of course, if the original mechanism does not conflict, the subsequently introduced SIBs can use both the original mechanism (i.e. configured in schedulingInfoList) and the new mechanism (i.e. configured in schedulingInfoList2).

[0145] Taking the above example in the prior art related to the present application as an example, if SI-1 to SI-7 use the original mechanism and SI-8 to SI-11 use the new mechanism, SI-1 to SI-7 are configured in schedulingInfoList, SI-8 to SI-11 are configured in schedulingInfoList2, the configuration in schedulingInfoList is as shown in Table 1 above, and the configuration in schedulingInfoList2 is as shown in Table 3, then when the ascending order is adopted and the offset value of the transmission window is not considered, the transmission window corresponding to each SI message is as shown in Figure 5 .

[0146] Table 3 Order table of each SI message in schedulingInfoList2 in scheduling information

[0147] Order in schedulingInfoList2 SI number Period (radio frame) 1 SI-8 16 2 SI-9 32 3 SI-10 32 4 SI-11 32

[0148] Another case is that the SI message configured earlier in schedulingInfoList2 can be transmitted first, and the specific method is to determine the transmission window from the tail to the head of the transmission period corresponding to the SI message according to the order position (from back to front) of the SI message in schedulingInfoList2, for example, if the SI message is the last one (the first one in reverse order), the SI message is transmitted in the first transmission window from the tail to the head of the transmission period corresponding to the SI message, if the SI message is the second one in reverse order, the SI message is transmitted in the second transmission window from the tail to the head of the transmission period corresponding to the SI message, i.e. when the reverse order is adopted and the offset value of the transmission window is not considered, the transmission window corresponding to each SI message is as shown in Figure 6 .

[0149] The terminal determines the transmission window of the SI message according to the above mechanism, so as to receive the corresponding SI message in the transmission window.

[0150] It should be noted that in this specific application, the idle transmission window can be fully utilized, so that the cell can transmit more SI messages, while ensuring the accurate transmission of the SI messages.

[0151] Specific application case two,

[0152] In the first specific application case, the base station always determines the transmission window from the last transmission window at the tail of the transmission period. In order to transmit the SI message earlier, in this case, an offset value of the transmission window can be configured in the schedulingInfoList2 information element, that is, the SI message is transmitted from the tail of the transmission period to the head by N transmission windows. For example, in the above example, if the configured offset value is 1 transmission window, then when the ascending order is used, the transmission window corresponding to each SI message is as shown in the following table. Figure 7

[0153] The implementation of A12 that can be used is described in detail as follows.

[0154] I. Indication of the transmission window for the first SI message

[0155] Specifically, in this case, the scheduling information list further includes first indication information of the transmission window corresponding to the first SI message.

[0156] The first indication information is used to indicate the position of the SI message along the direction from the tail to the head of the corresponding transmission period.

[0157] That is, in this case, the access network device indicates the position of the transmission window corresponding to each SI message in the scheduling information list. Specifically, the indication is usually indicated by a label. For example, when the first indication information corresponding to the first SI message is 1, it means that the transmission window of the first SI message is located at the last transmission window of the transmission period corresponding to the first SI message. When the first indication information corresponding to the first SI message is 3, it means that the transmission window of the first SI message is located at the third transmission window from the end of the transmission period corresponding to the first SI message.

[0158] Specific application case three,

[0159] ​In consideration of idle transmission windows at the tail of each cycle, in order to utilize these idle transmission windows, the position of the transmission window corresponding to the SI message can be directly configured in schedulingInfoList2 from the tail to the head. For example, if the configured position of the transmission window is 1, it indicates that the transmission window of the SI message is the first transmission window from the tail to the head; if the configured position of the transmission window is 2, it indicates that the transmission window of the SI message is the second transmission window from the tail to the head; and so on. For example, the configuration in schedulingInfoList2 is shown in Table 4, and the transmission window corresponding to each SI message is shown in Table 5. Figure 8

[0160] Table 4: Table for matching the order of each SI message in schedulingInfoList2 and the position of the transmission window in the scheduling information

[0161] Order in schedulingInfoList2 SI number Period (radio frame) Position of transmission window 1 SI-8 16 1 2 SI-9 32 3 3 SI-10 32 4 4 SI-11 32 9

[0162] II. Transmission window indication for only part of the SI messages in the scheduling information list

[0163] Specifically, in this case, the scheduling information list includes the scheduling information of a second SI message, the scheduling information of the second SI message includes the position of the transmission window of the second SI message and the transmission cycle of the second SI message, and the position of the transmission window of the second SI message is the mth transmission window in the direction from the head to the tail of the transmission cycle of the second SI message; wherein the second SI message is the last adjacent SI message of the first SI message in the scheduling information list.

[0164] The determination of the transmission window of the first SI message according to the transmission window indicated by the access network device includes:

[0165] When the scheduling information of the first SI message does not include the position of the transmission window of the first SI message, the terminal determines the position of the transmission window of the first SI message as the (m+1)th transmission window in the direction from the head to the tail of the transmission cycle of the first SI message.

[0166] Wherein m is a positive integer.

[0167] ​That is, in this case, the corresponding start window is configured for part of the SI messages in the scheduling information list, and the corresponding start window is not configured for another part of the SI messages. For the SI message for which the start window is configured, the start window is directly used as the transmission window of the SI message. For the SI message for which the start window is not configured, the transmission window of the SI message is determined according to the transmission window of the adjacent previous SI message, that is, the transmission window of the SI message is the next transmission window of the transmission window of the adjacent previous SI message. It should be noted that if the adjacent previous SI message does not have the corresponding start window, the above rule is used again until the transmission window of the SI message is determined. Since the configuration of the start window needs to occupy the transmission resource, part of the SI messages do not have the start window, thereby saving the signaling overhead and reducing the occupation of the air interface resource.

[0168] Specific application case four,

[0169] The position of the transmission window (that is, the start window) of the SI message in the schedulingInfoList2 is specified, but it is not necessary to specify the start window for each SI message, that is, only part of the SI messages are specified. For the SI message for which the start window is specified, the start window is directly used as the transmission window of the SI message. For the SI message for which the start window is not specified, the transmission window of the SI message is the next window of the transmission window of the SI message in the schedulingInfoList2. For example, the configuration in the schedulingInfoList2 is shown in Table 5, the transmission window of SI-9 is the next window of the transmission window of SI-8, that is, the 12th window; the transmission window of SI-10 is the next window of the transmission window of SI-9, that is, the 13th window; the transmission window of SI-11 is directly specified to use the 15th window; the transmission window of SI-12 is the next window of the transmission window of SI-11, that is, the 16th window. Specifically, the transmission window corresponding to each SI message is shown in Table 6. Figure 9

[0170] Table 5: Correspondence table of the order of each SI message in the scheduling information and the position of the transmission window in the schedulingInfoList2

[0171] Order in schedulingInfoList2 SI number Period (radio frame) Position of transmission window 1 SI-8 16 11 2 SI-9 32 Not specified 3 SI-10 32 Not specified 4 SI-11 32 15 5 SI-12 32 Not specified

[0172] Three, indicating the start window by the scheduling information list

[0173] It should be noted that in this case, the method further includes:

[0174] The terminal receives second indication information;

[0175] The second indication information is used to indicate the start window of the scheduling information list.​

[0176] determining the transmission window of the first SI message according to the transmission window indicated by the access network device comprises:

[0177] determining the transmission window of the first SI message according to the order position of the first SI message in the scheduling information list and the start window.

[0178] That is, the access network device configures a start window for the scheduling information list, that is, the start window is a start window at the scheduling information list level, which generally indicates the position of the transmission window of the first SI message in the scheduling information list or the position of the transmission window of the last SI message.

[0179] Optionally, the specific implementation manner of determining the transmission window of the first SI message according to the order position of the first SI message in the scheduling information list and the start window is:

[0180] in the case that the start window is x and the first SI message is the yth SI message in the list in the forward order or the reverse order, the transmission window of the first SI message is determined as the x+y-1th transmission window in the direction from the head to the tail of the transmission period of the first SI message;

[0181] wherein x and y are positive integers.

[0182] Specific application case five,

[0183] Considering that the size of SIB1 is limited and the idle transmission windows are generally continuous, in this case, a start window is associated for schedulingInfoList2 (the start window per list, thereby saving signaling overhead), which can be considered as the start window of the period of reference frame 0, and each SI message in this schedulingInfoList2 is sequentially ordered from this start window according to the order, thereby determining the transmission window position of each SI message in the respective period, or, in other words, the start window is the transmission window of the first SI message in schedulingInfoList2. For example, for Table 3, if the start window is set to 11, the first SI message SI-8 in schedulingInfoList2 uses the 11th transmission window, the second SI message SI-9 uses the 12th transmission window, and the third SI message SI-10 uses the 13th transmission window, and so on. Specifically, the transmission windows corresponding to the SI messages are as shown in Table 4. Figure 10

[0184] Optionally, one implementation manner of the above A13 can be adopted as follows:​

[0185] When the transmission window of the first SI message collides in the transmission period corresponding to the first SI message, determining an idle transmission window after the collision position of the transmission window of the first SI message.

[0186] Specific application case six,

[0187] The main idea of this implementation is that the arrangement from the head to the tail of the transmission period is still adopted, but when the collision occurs, the part of the previous period that collides is skipped to occupy the position, and is moved backward until an (nearest) idle transmission window is found, for example, the Figure 3 After this implementation is adopted, the transmission window corresponding to each SI message is as shown in Figure 11 .

[0188] It should be further explained that, since the SI message used for positioning is transmitted separately, optionally, the scheduling information list in the embodiment of the present application can not contain the SI message used for positioning, or the scheduling information list can also be a list concatenated with the first list, for example, a scheduling information list generated by concatenating the first list after schedulingInfoList2.

[0189] The first list is a list of SI messages used for positioning.

[0190] It should be noted that, by configuring the SI message to determine the transmission window from the tail to the head of the transmission period corresponding to the SI message, the embodiment of the present application makes full use of the idle transmission window, so that the cell can broadcast more SI messages to meet the needs of the service, while ensuring to meet the needs of transmitting more SI messages; or by indicating the transmission window of part of the SI messages, the signaling overhead can be reduced to ensure to meet the needs of transmitting more SI messages; or by directly moving the conflicting SI messages to the transmission window without collision for transmission when configuring, the needs of transmitting more SI messages can be ensured.

[0191] It should be noted that the system information transmission method provided by the embodiment of the present application can be executed by a system information transmission device, or a control module in the system information transmission device for executing the system information transmission method.

[0212] when the scheduling information of the first SI message does not include the position of the sending window of the first SI message, the terminal determines that the position of the sending window of the first SI message is an m+1-th sending window in a direction from a head of a sending period of the first SI message to a tail.

[0358] The access network device embodiment corresponds to the above-mentioned access network device method embodiment. Each implementation process and implementation manner of the above-mentioned method embodiment can be applied to the access network device embodiment and can achieve the same technical effects.

[0359] Specifically, the embodiment of the present application further provides an access network device. As shown in the Figure 16 The access network device 1600 comprises an antenna 1601, a radio frequency device 1602, and a baseband device 1603. The antenna 1601 is connected to the radio frequency device 1602. In the uplink direction, the radio frequency device 1602 receives information through the antenna 1601 and sends the received information to the baseband device 1603 for processing. In the downlink direction, the baseband device 1603 processes the information to be sent and sends it to the radio frequency device 1602. The radio frequency device 1602 processes the received information and sends it out through the antenna 1601.

[0360] The above-mentioned frequency band processing device can be located in the baseband device 1603. The method performed by the network side device in the above embodiment can be implemented in the baseband device 1603. The baseband device 1603 comprises a processor 1604 and a memory 1605.

[0361] The baseband device 1603 may, for example, comprise at least one baseband board on which a plurality of chips are arranged, as shown in the Figure 16 One of the chips is, for example, the processor 1604, which is connected to the memory 1605 to call the programs in the memory 1605 and perform the operations of the access network device shown in the above method embodiment.

[0362] The baseband device 1603 can further include a network interface 1606 for interacting information with the radio frequency device 1602, for example, a common public radio interface (CPRI).

[0363] Specifically, the access network device of the embodiment of the present application further includes instructions or programs stored in the memory 1605 and executable on the processor 1604, and the processor 1604 invokes the instructions or programs in the memory 1605 to execute the method shown in the above Figure 15 The modules shown in the above perform the method shown in the above and achieve the same technical effects, and thus will not be described herein.

[0364] As shown in the above Figure 17 The embodiment of the present application provides a system information transmission method, including:

[0365] Step 1701, a terminal receives scheduling information list sent by an access network device;

[0366] It should be noted that the scheduling information list at least includes scheduling information of a third system information (SI) message, and the scheduling information of the third SI message includes a transmission period corresponding to the third SI message.

[0367] It should be noted that in the embodiment of the present application, the scheduling information list further includes at least one SI message placeholder element whose ordering position in the scheduling information list is in front of the scheduling information of the third SI message, the SI message placeholder element occupies an element position in the scheduling information list, and does not correspond to an SI message, or in other words, does not perform SI message transmission when corresponding to a transmission window, that is, the SI message placeholder element does not correspond to an SI message.

[0368] It should be noted that in the embodiment of the present application, an element can be considered as a basic unit for constituting a list or an array, and can also be referred to as an entry, an item, etc.

[0369] Step 1702, the terminal determines a transmission window of the third SI message;

[0370] Step 1703, the terminal receives the third SI message in the transmission window.

[0371] It should be further noted that the SI message placeholder element corresponds to an empty structure or the filling content of the SI message placeholder element is empty, that is, the SI message placeholder element is actually an empty element.

[0372] It should be noted that, in the embodiments of the present application, the SI message placeholder element is added in the scheduling information list, the SI message placeholder element and the scheduling information of the SI message are taken as the elements of the scheduling information list, although the SI message placeholder element occupies an element position of the scheduling information list, when the transmission window of the SI message is determined, the SI message placeholder element corresponds to one transmission window, but does not actually correspond to one SI message, or in other words, when the transmission window is corresponded to, the SI message is not transmitted, so as to effectively avoid the conflicting SI window, and the idle window behind can be used, so as to ensure that the demand of transmitting more SI messages is met. It should be noted that the SI message placeholder element does not cause the SI message to be transmitted, but does not mean that the transmission window corresponding to the SI message placeholder element does not transmit the SI message, and the transmission window can be used to transmit the originally conflicting SI message, such as the short-period SI message of the next period. Further, even in the case of no conflict, the SI message placeholder element can be set in such a manner of scheduling information list, so that the transmission window corresponding to the SI message placeholder element does not transmit the SI message, so as to save more resources in the SI transmission window to transmit other data, and through the mechanism of the SI message placeholder element, the SI messages can also be dispersed in the entire period, instead of always being concentrated in the head or tail of the period.

[0373] Optionally, the implementation manner that can be adopted by step 1702 of the present application is as follows:

[0374] The terminal determines the transmission window of the third SI message according to a second rule.

[0375] The second rule includes one of the following:

[0376] C11, according to the sorting position of the third SI message in the scheduling information list and the direction from the tail to the head of the transmission period corresponding to the third SI message, the transmission window of the third SI message in the transmission period corresponding to the third SI message is determined.

[0377] That is, this way is to determine the transmission window in the direction from the tail to the head of the transmission period, which can effectively utilize the idle transmission window and avoid the conflict of the SI message as much as possible, so that the access network device can transmit more SI messages.

[0378] For example, if the third SI message is located at the qth in the scheduling information list, the third SI message is transmitted in the qth transmission window in the transmission period corresponding to the third SI message.

[0379] C12, determining the transmission window of the third SI message in the transmission period corresponding to the third SI message in a direction from the second position to the head of the transmission period corresponding to the third SI message according to the order of the third SI message in the scheduling information list and the order of the SI messages in the scheduling information list;

[0380] For example, if the third SI message is the qth in the scheduling information list, the third SI message is transmitted in the qth transmission window in the transmission period corresponding to the third SI message.

[0381] Optionally, an implementation manner of C11 can be adopted as follows:

[0382] determining the transmission window of the third SI message in the transmission period corresponding to the third SI message in a direction from the second position to the head of the transmission period corresponding to the third SI message according to the order of the third SI message in the scheduling information list and the order of the SI messages in the scheduling information list;

[0383] The second position is the last transmission window of the tail of the transmission period corresponding to the third SI message, or the second position is the last transmission window of the tail of the transmission period corresponding to the third SI message minus an offset value of the transmission window.

[0384] It should be noted that the specific implementation manner of determining the transmission window of the third SI message is as follows:

[0385] When the third SI message is the hth in the order or the reverse order in the scheduling information list, the transmission window of the third SI message is determined as the hth transmission window in a direction from the second position to the head of the transmission period corresponding to the third SI message;

[0386] The h is a positive integer.

[0387] For example, when the forward order is adopted and the offset value of the transmission window is not considered, if the third SI message is the 3rd in the scheduling information list, the transmission window of the third SI message is the third last transmission window in the transmission period corresponding to the third SI message; when the forward order is adopted and the offset value of the transmission window is considered (the offset value is 1, that is, offset by one transmission window), if the third SI message is the 3rd in the scheduling information list, the transmission window of the third SI message is the fourth last transmission window in the transmission period corresponding to the third SI message.

[0388] For example, when the reverse order is adopted and the offset value of the transmission window is not considered, if the third SI message is the fourth last SI message in the scheduling information list, the transmission window of the third SI message is the fourth last transmission window in the transmission period corresponding to the third SI message; when the reverse order is adopted and the offset value of the transmission window is considered (at this time, the offset value is 2, that is, offset by two transmission windows), if the third SI message is the fourth last SI message in the scheduling information list, the transmission window of the third SI message is the sixth last transmission window in the transmission period corresponding to the third SI message.

[0389] Optionally, it also needs to be explained that in the case where the second position is the last transmission window at the tail of the transmission period corresponding to the third SI message minus the offset value of the transmission window, the method further comprises:

[0390] The terminal receives the offset value of the transmission window sent by the access network device.

[0391] That is, in this case, the access network device will inform the terminal of the offset value of the transmission window, and usually the offset value can be sent to the terminal together with the scheduling information list in SIB1.

[0392] It also needs to be explained that the scheduling information list meets at least one of the following:

[0393] D11, the SI message in the scheduling information list is an SI message for non-positioning;

[0394] D12, the SI message in the scheduling information list is an SI message for positioning;

[0395] D13, the scheduling information list is a list of concatenated target lists;

[0396] It needs to be explained that the target list includes at least one of the following:

[0397] D131, a list of one or more SI messages for non-positioning;

[0398] D132, a list of one or more SI messages for positioning.

[0399] It needs to be explained that the scheduling information list in the existing SIB1 in the embodiments of the present application is a list of SI messages for non-positioning, and the existing list of SI messages for positioning is called posSchedulingInfoList. In the case of not considering backward compatibility, such as future 6G, the scheduling information list in this embodiment can be a separate schedulingInfoList with an empty element, a separate posSchedulingInfoList.

[0400] For the current 5G system information scheduling, backward compatibility needs to be considered, one possible way is to introduce a new scheduling information list, such as adding a list of SI message placeholder elements for non-positioning SI messages called schedulingInfoList3, an example of its structure is as follows:

[0401]

[0402] schedulingInfoList3 can include multiple elements, some of which correspond to empty elements (i.e. choice null of SchedulingInfo2-r17 structure), and some of which correspond to SI messages (i.e. choice schedulingInfo-r17 of SchedulingInfo2-r17 structure).

[0403] Adding a list of SI message placeholder elements for positioning SI messages called posSchedulingInfoList2, an example of its structure is as follows:

[0404]

[0405]

[0406] This new scheduling information list is concatenated with the existing scheduling information list (schedulingInfoList or posSchedulingInfoList) to form a list (for the convenience of description, it becomes a concatenated list). Specifically, the new scheduling information list can be placed after the existing scheduling information list to generate a concatenated list. Even multiple lists can be concatenated, and the position of the sending window is determined based on the position order in the concatenated list, that is, if an SI message is the xth element in the concatenated list, the xth sending window or the last xth sending window of the sending window of the sending period corresponding to the SI message is sent.

[0407] For example, when two lists generate a concatenated list, schedulingInfoList can be concatenated with schedulingInfoList3, or schedulingInfoList can be concatenated with posSchedulingInfoList2, or posSchedulingInfoList can be concatenated with schedulingInfoList3, or posSchedulingInfoList can be concatenated with posSchedulingInfoList2.

[0408] For example, when three lists generate concatenated lists, it can be schedulingInfoList concatenated with posSchedulingInfoList and schedulingInfoList3, or schedulingInfoList concatenated with posSchedulingInfoList and posSchedulingInfoList2, or schedulingInfoList concatenated with schedulingInfoList3 and posSchedulingInfoList2, or posSchedulingInfoList concatenated with schedulingInfoList3 and posSchedulingInfoList2.

[0409] For example, when four lists generate concatenated lists, it can be schedulingInfoList concatenated with posSchedulingInfoList, schedulingInfoList3 and posSchedulingInfoList2 in sequence.

[0410] The specific application of this embodiment is specifically described as follows.

[0411] Specific application case seven,

[0412] Taking the above examples in the prior art related to the present application as examples, if SI-1 to SI-7 use the original mechanism and SI8 to SI11 use the new mechanism, SI1 to SI7 are configured in schedulingInfoList and SI8 to SI11 are configured in schedulingInfoList3, according to the existing mechanism, the transmission window of SI-9 and SI-10 conflicts with the occurrence window of the next period of SI-1 and SI-2, in order to avoid the conflict, the second and third elements of schedulingInfoList3 can be set to null elements, SI-9 and subsequent SI messages are sequentially moved backward, and the configuration in schedulingInfoList3 is as shown in the table:

[0413] Table 6: Order of each SI message in schedulingInfoList3 in scheduling information

[0414]

[0415] The concatenated schedulingInfoList and schedulingInfoList3 are as shown in Table 7:

[0416] Table 7: Order of each SI message in the scheduling information list

[0417]

[0418]

[0419] When the order is ascending and the offset value of the sending window is not considered, the sending window corresponding to each SI message is as shown in the following table. Figure 18

[0420] It should be noted that, by setting an empty element in the scheduling information list, the embodiment of the present application can avoid conflicts, so as to make full use of the idle sending window, so that the cell can broadcast more SI messages, meet the needs of the service, and at the same time, meet the needs of sending more SI messages.
