The prior art related to the present application is briefly described below.

The system information of a cell is periodically broadcast, comprising a master information block (Master Information Block, MIB) and a series of system information blocks (System Information Block, SIBs). The MIB is carried on a broadcast channel (Broadcast Channel, BCH) in the form of MIB messages and is broadcast periodically with a fixed periodicity of 80 ms. The MIB message contains cell barring status information and physical layer information necessary for acquiring further system messages. A series of system information blocks includes SIB1 and other SIBs (SIB 2, SIB3, …). The SIB1 is periodically broadcast in a fixed 160ms period in a SIB1 message, and the SIB1 message defines scheduling of other SIBs on one hand and includes a message required by initial access on the other hand.

Other SIBs are periodically broadcast in a configured periodicity in the form of system information (System Information, SI) messages. The scheduling information of 1 or more SI messages may be configured in SIB1, and the scheduling information includes a period of each SI message and one or more SIBs mapped thereon, that is, those SIBs having the same period are mapped to be transmitted in this SI message. Different SI messages may have different periods or the same period, depending on the scheduling configuration in SIB 1. After the UE reads the corresponding SI information, the SIB carried in the SI information is obtained.

The period of the SI message is calculated starting from the start boundary of frame 0. From a time domain perspective, each SI message starts from the beginning of the period of the SI message and occupies one transmission window to be transmitted. The length of the transmission window is configured in SIB1 (i.e., SI-WindowLength cell), and all SI messages have the same transmission window length. Each transmission window can only transmit the same SI message, i.e. the transmission of SI messages is serial. When the starting boundaries of periods of the SI messages are the same (for example, all SI messages need to be sent from frame 0), they are sent according to the order in which they appear in the scheduling information (scheduling info list) of SIB1, that is, they appear in the scheduling information before they appear.

For example: assuming that the length of the transmission window of the cell takes s20, that is, 20 slots (slots), and the subcarrier spacing of the cell is 30kHz, one transmission window occupies 1 radio frame (10 ms). The scheduling information configured in SIB1 is assumed, and the order of each SI message in the scheduling information is shown in table 1.

Table 1 scheduling information configured with SIB1 and one of the order lookup tables of each SI message in the scheduling information

Order in scheduling information	SI numbering	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

The transmission of each SI message is as shown in fig. 2. The network needs to ensure that the SI messages sent in sequence cannot exceed the start of the next period of the shortest period SI messages, otherwise collisions will occur. Therefore, the maximum number of SI messages that can be configured depends on the shortest period of the SI messages that are configured and the transmission window length, i.e., (maximum number of SI messages that can be configured) = (shortest period of SI messages that are configured) divided by (transmission window length). If in the above example, SI8-SI11 is also required to be sent, as shown in Table 2:

table 2 second of SIB1 configured scheduling information and sequence of each SI message in the scheduling information

Then, according to the existing transmission scheme of SI messages, the transmission windows of SI-9, SI-10, SI-11 are out of range of the shortest period and overlap with the transmission window of the next period of SI-1 and SI-2 of 8 radio frames, resulting in collision, as shown in fig. 3, although some idle resources (transmission windows marked as empty) still exist.

As standard protocols evolve, more SIBs may need to be introduced, as will more SI messages, such as the positioning feature will introduce a large number of SI messages. The existing mechanisms described above may not support future requirements.

The method, the device, the terminal and the access network device for transmitting the system information provided by the embodiment of the application are described in detail below through some embodiments and application scenes thereof with reference to the accompanying drawings.

As shown in fig. 4, an embodiment of the present application provides a system information transmission method, including:

step 401, a terminal receives a scheduling information list sent by access network equipment;

it should be noted that, the scheduling information list includes at least scheduling information of a first System Information (SI) message, where the scheduling information of the first SI message includes a transmission period corresponding to the first SI message;

it should be noted that the schedule information list in the embodiment of the present application is different from the schedule information list in the existing SIB1, that is, the schedule information list in the existing SIB1 is one table, and the schedule information list in the embodiment of the present application is another table in the SIB1 different from the schedule information list in the existing SIB 1. That is, the SI message in the scheduling info list in the existing SIB1 adopts one transmission rule, and the SI message in the scheduling information list in the embodiment of the present application adopts another new transmission rule.

The first SI message in the embodiment of the present application refers to any one SI message in the scheduling information list that the terminal needs to receive.

Step 402, the terminal determines a sending window of the first SI message according to a first rule;

here, the first rule includes one of the following:

a11, determining a transmission window of the first SI message in the transmission period corresponding to the first SI message according to the ordering position of the first SI message in the scheduling information list and the transmission period corresponding to the first SI message along the tail-to-head direction;

it should be noted that, in this manner, it is considered that the idle transmission windows are at the tail of each transmission period, and in order to use these idle transmission windows, the transmission windows are determined in the direction from the tail of the transmission period to the head, so that the idle transmission windows can be effectively used, and the SI messages can be avoided as much as possible, so that the access network device can transmit more SI messages.

A12, determining a transmission window of the first SI message according to the transmission window indicated by the access network equipment;

in this way, by indicating the transmission window, the transmission window falls on the idle transmission window, so as to avoid the conflict of the SI messages, and the access network device can transmit more SI messages;

A13, determining a transmission window of the first SI message in the transmission period corresponding to the first SI message according to the ordering position of the first SI message in the scheduling information list and the transmission period corresponding to the first SI message along the direction from the head to the tail in a mode of skipping the conflict SI message;

it should be noted that, in this way, the transmission window is determined by skipping the conflict, so that the idle transmission window can be fully utilized, the conflict of the SI messages is effectively avoided, the access network device can transmit more SI messages, and the accurate transmission of the SI messages can be further ensured.

Step 403, the terminal receives the first SI message in the sending window;

it should be noted that, in the embodiment of the present application, the SI message sending window is determined by effectively using an idle sending window, so that the need for sending more SI messages can be met.

Alternatively, one implementation manner of the a11 may be:

determining a sending window of the first SI message in a sending period corresponding to the first SI message according to the ordering position of the first SI message in the scheduling information list and the sending period corresponding to the first SI message along the direction from the first position to the head according to the forward sequence or the reverse sequence of the SI message in the scheduling information list;

The first position is the last transmitting window at the tail of the transmitting period corresponding to the first SI message, or the first position is the last transmitting window at the tail of the transmitting period corresponding to the first SI message minus the offset value of the transmitting window.

It should be noted here that, a specific implementation manner of determining the sending window of the first SI message is:

when the first SI message is an a-th SI message in a positive sequence or a reverse sequence in the scheduling information list, determining that a transmission window of the first SI message is an a-th transmission window in a direction from a first position to a head in a transmission period corresponding to the first SI message;

wherein a is a positive integer.

For example, when the positive sequence is adopted and the offset value of the transmission window is not considered, if the first SI message is the 1 st SI message in the scheduling information list, the transmission window of the first SI message is the last transmission window in the transmission period corresponding to the first SI message; when the positive sequence is adopted and the offset value of the transmission window is considered (the offset value is 2 at this time, namely, two transmission windows are offset), if the first SI message is the 1 st SI message in the scheduling information list, the transmission window of the first SI message is the last third transmission window in the transmission period corresponding to the first SI message.

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 last 2 nd SI message in the scheduling information list, the transmission window of the first SI message is the last second 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 (the offset value is 2 at this time, namely, two transmission windows are offset), if the first SI message is the last 2 SI messages in the scheduling information list, the transmission window of the first SI message is the last fourth transmission window in the transmission period corresponding to the first SI message.

Optionally, it should also be noted that, in a 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 includes:

and the terminal receives the offset value of the sending window sent by the access network equipment.

That is, in this case, the access network device will inform the terminal of the offset value of the transmission window, which may be typically transmitted to the terminal together with the scheduling information list in SIB 1.

The specific application condition is that,

To take into account that the free transmission windows are at the end of each period, for utilizing these free transmission windows, for some SI messages it may be configured to determine the transmission window starting from the end of the period of the SI message towards the head. A list of scheduling information is newly introduced, such as a scheduling info list2 cell (the name is only an example and not limiting in the embodiment of the present application), and SI messages configured in the list of scheduling information use a new mechanism. Specifically, according to the ordering position of a certain SI message in the scheduling info list2, a transmission window is determined from the tail of the transmission period corresponding to the SI message to the head, for example, if the SI message is first, the SI message is transmitted in the first transmission window from the tail of the transmission period corresponding to the SI message to the head, if the SI message is second, the SI message is transmitted in the second transmission window from the tail of the transmission period corresponding to the SI message to the head, and so on. It should be noted here that SI messages configured in existing schedulinglnfolist cells still use existing mechanisms.

Optionally, considering backward compatibility, these SI messages using the new mechanism (i.e. SI messages configured in schedulinglnfolist 2) exclude SIBs already defined by the current standard, such as SIB2-SIB14, which use the original mechanism, i.e. the subsequently introduced SIBs can only be mapped into these SI messages for transmission. Of course, if the original mechanism is not conflicting, the subsequently introduced SIB can use either the original mechanism (i.e., configured in the schedulingInfoList) or the new mechanism (i.e., configured in the schedulingInfoList 2).

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 the schedulinglnfolist, SI-8 to SI-11 are configured in the schedulinglnfolist 2, the configuration in the schedulinglnfolist is shown in table 1, the configuration in the schedulinglnfolist 2 is shown in table 3, and when the positive sequence is adopted and the offset value of the transmission window is not considered, the transmission window corresponding to each SI message is shown in fig. 5.

Table 3 sequence table of SI messages in scheduling information in schedulingInfoList2

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

Another case is: the SI message configured before in the schedulingInfoList2 may be sent first, specifically, the sending window is determined from the tail of the sending period corresponding to the SI message to the head according to the ordering position (from the back to the front) of the SI message in the schedulingInfoList2, for example, if the SI message is the last (first last) SI message is sent from the tail of the sending period corresponding to the SI message to the first sending window in the head direction, if the SI message is the second last SI message is sent from the tail of the sending period corresponding to the SI message to the second sending window in the head direction, that is, when the reverse order is adopted and the offset value of the sending window is not considered, the sending windows corresponding to the SI messages are shown in fig. 6.

The terminal determines a sending window of the SI message according to the above mechanism, thereby receiving the corresponding SI message in the sending window.

It should be noted that, in this specific application case, the idle sending window can be fully utilized, so that the cell can send more SI messages, and meanwhile, the accurate transmission of the SI messages can be ensured.

Specific application condition II,

In a specific application case one, the base station always determines the transmission window from the last transmission window at the end of the transmission period, in order to enable the SI message to be transmitted earlier, in this case, an offset value of one transmission window may be configured in the schedulinglnfolist 2 cell, i.e. the SI message starts to be transmitted only when N transmission windows are offset from the end of the transmission period to the head. For example, in the above example, if the configured offset value is 1 transmission window, when positive sequence is adopted, the transmission window corresponding to each SI message is as shown in fig. 7.

The following describes in detail the possible implementation of the above a 12.

1. Indication of a transmission window for a first SI message

Specifically, in this case, the scheduling information list further includes: the first indication information of the sending window corresponding to the first SI message;

The first indication information is used for indicating the position of the SI message along the direction from the tail part to the head part of the corresponding sending period.

That is, in this case, the access network device indicates, for each SI message in the scheduling information list, the position of its corresponding transmission window, specifically, typically, the indication is indicated by a reference sign, for example, when the first indication information corresponding to the first SI message is 1, it indicates that the transmission window of the first SI message is located in the last transmission window of the transmission period corresponding to the first SI message, and when the first indication information corresponding to the first SI message is 3, it indicates that the transmission window of the first SI message is located in the last third transmission window of the transmission period corresponding to the first SI message.

The specific application condition is three,

Considering that the idle transmission windows are at the tail of each period, in order to utilize the idle transmission windows, the positions of the transmission windows from the tail to the head of the transmission period corresponding to the SI message can be directly configured in the schedulinglnfolist 2. For example, if the position of the configured 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, and if the position of the configured 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 the schedulingInfoList2 is shown in Table 4, and the transmission window corresponding to each SI message is shown in FIG. 8.

2. Transmitting window indication only for partial SI message in scheduling information list

Specifically, in this case, the scheduling information list includes scheduling information of a second SI message, the scheduling information of the second SI message including a position of a transmission window of the second SI message, which is an mth transmission window in a direction from a head to a tail of the transmission period of the second SI message, and a transmission period of the second SI message; wherein the second SI message is a last adjacent SI message of the first SI message in the scheduling information list;

the determining the sending window of the first SI message according to the sending window indicated by the access network device includes:

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 that the position of the transmission window of the first SI message is the (m+1) th transmission window along the direction from the head to the tail of the transmission period of the first SI message;

Wherein m is a positive integer.

That is, in this case, a corresponding start window is configured for a part of SI messages in the scheduling information list, and the other part of SI messages does not configure a corresponding start window. For the SI message with the configured start window, the start window is directly used as the sending window of the SI message, and for the SI message without the configured start window, the sending window of the SI message is determined according to the sending window of the last SI message adjacent to the start window, namely the sending window of the SI message is the next sending window of the last SI message adjacent to the sending window of the SI message. It should be noted that, if the corresponding start window is not configured in the adjacent previous SI message, the above rule is used again until it is determined that the transmission window is obtained; because the configuration of the start window needs to occupy the transmission resource, part of SI information does not configure the start window, thereby saving signaling overhead and reducing the occupation of air interface resources.

The specific application condition is four,

The position of the transmission window (i.e., the start window) is specified for SI messages in schedulinglnfolist 2, but it is not necessary to specify for each SI message, i.e., only a portion. For the SI message with the designated start window, directly using the start window as a sending window of the SI message; for SI messages for which no start window is specified, its send window is the next window to the send window of the previous SI message for the SI message's position in schedulinglnfolist 2. For example, if 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, i.e. the 12 th window; the transmission window of SI-10 is the next window of the transmission window of SI-9, i.e. 13 th window; the transmission window of SI-11 directly designates the 15 th window; the transmission window of SI-12 is the next window of the transmission window of SI-11, i.e. the 16 th window; specifically, the transmission window corresponding to each SI message is shown in fig. 9.

Table 5 schedule Info list2 sequence of SI messages in scheduling information and position of transmission window

				1	SI-8	16	11

4	SI-11	32	15
				5	SI-12	32	Unspecified

3. Indicating a start window for a list of scheduling information

In this case, the method further includes:

the terminal receives the second indication information;

wherein the second indication information is used for indicating a start window of the scheduling information list;

and the terminal determines a sending window of the first SI message according to the ordering position of the first SI message in the scheduling information list and the starting window.

That is, the access network device configures a start window for the scheduling information list, i.e. the start window is a start window of the scheduling information list level, which typically indicates the position of the transmission window of the first SI message or the position of the transmission window of the last SI message in the scheduling information list.

Optionally, the specific implementation manner of determining the sending window of the first SI message according to the ordering position of the first SI message in the scheduling information list and the starting window is:

When the start window is x and the first SI message is a y-th SI message in a positive sequence or a reverse sequence in a list, determining that a transmission window of the first SI message is an x+y-1-th transmission window along a direction from a head to a tail of a transmission period of the first SI message;

wherein x and y are positive integers.

The specific application condition is five,

Considering that SIB1 is limited in size and that the idle transmission window is generally continuous, in this case, a start window (the start window of the per list, thereby saving signaling overhead) is associated to the schedulinglnfolist 2, which may be considered as the start window of the period of reference frame 0, and each SI message in the schedulinglnfolist 2 is ordered sequentially from this start window in order of precedence, thereby determining the position of the transmission window of each SI message in the respective period, or, in other words, the transmission window of the first SI message in the schedulinglnfolist 2. For example, for table 3, if the start window is set to 11, the first SI message SI-8 in the schedulinglnfolist 2 uses the 11 th transmission window, the second SI message SI-9 uses the 12 th transmission window, the third SI message SI-10 uses the 13 th transmission window, and so on, and specifically, the transmission window corresponding to each SI message is shown in fig. 10.

Alternatively, one implementation manner of the a13 may be:

and when the transmission window of the first SI message collides in the transmission period corresponding to the first SI message, determining that the transmission window of the first SI message is positioned in an idle transmission window behind the collision position.

The specific application situation is six,

The main idea of this implementation is that the head-to-tail arrangement along the transmission period is still adopted, but when a collision occurs, the part of the previous period that collides skips the occupied position, and moves backward until a (nearest) idle transmission window is found, for example, after adopting this implementation in fig. 3 in the related art of the present application, the transmission window corresponding to each SI message is shown in fig. 11.

It should be further noted that, since the SI message for positioning is sent separately, alternatively, the scheduling information list in the embodiment of the present application may not include the SI message for positioning, or the scheduling information list may be a list of a first list in series, for example, a scheduling information list generated after the first list is connected in series to the schedulinglnfolist 2;

wherein the first list is a list of SI messages for positioning.

It should be noted that, in the embodiment of the present application, the SI message is configured to determine the transmission window from the tail to the head of the transmission period corresponding to the SI message, so that the idle transmission window is fully utilized, so that the cell can broadcast more SI messages, thereby meeting the service requirement, and simultaneously ensuring that the requirement of transmitting more SI messages is met; or by indicating a transmission window of part of the SI information, the signaling overhead can be reduced, and the requirement of transmitting more SI information is met; or when in configuration, the conflicted SI information is directly moved to a sending window which does not generate confliction for sending, so that the requirement of sending more SI information can be met.

As shown in fig. 17, an embodiment of the present application provides a system information transmission method, including:

step 1701, a terminal receives a scheduling information list sent by access network equipment;

it should be noted that, the scheduling information list includes at least scheduling information of a third system information SI message, where the scheduling information of the third SI message includes a transmission period corresponding to the third SI message.

It should be noted that, in this 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 before the scheduling information of the third SI message, where the SI message placeholder element occupies one element position in the scheduling information list and does not correspond to an SI message, or 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.

In the embodiment of the present application, an element (element) may be considered as a basic unit that composes a list or an array, and may also be referred to as an entry, an item, or the like.

Step 1702, the terminal determines a sending window of the third SI message;

step 1703, the terminal receives the third SI message in the sending window.

It should be further noted that the SI message placeholder element corresponds to a null structure or the padding content of the SI message placeholder element is null, that is, the SI message placeholder element is actually a null element.

It should be noted that, in the embodiment of the present application, by adding an SI message occupying element in the scheduling information list, where the SI message occupying element is used as an element of the scheduling information list together with the scheduling information of the SI message, although the SI message occupying element occupies one element position of the scheduling information list, when determining a transmission window of the SI message, the SI message occupying element corresponds to one transmission window, but does not actually correspond to one SI message, or does not actually perform SI message transmission when corresponding to the transmission window, so that a conflicting SI window is effectively avoided, and a subsequent idle window can be utilized, so as to ensure that the requirement of transmitting more SI messages is met. It should be noted that, the SI message placeholder element does not cause SI message transmission, but does not mean that the SI message is not transmitted by the transmission window corresponding to the SI message placeholder element, and the transmission window may be used to transmit the SI message that is originally conflicted, for example, to transmit the SI message of the short period of the next period. Furthermore, even if the scheduling information list is not in conflict, the SI message occupying element is set so that the SI message is not sent by the sending window corresponding to the SI message occupying element, so that more resources are saved in the SI sending window to send other data, and the SI message can be scattered to the whole period instead of being always concentrated at the head or tail of the period through the mechanism of the SI message occupying element.

Optionally, the implementation manner that may be adopted in step 1702 of the present application is:

the terminal determines a sending window of the third SI message according to a second rule;

wherein the second rule comprises one of:

c11, determining a transmission window of the third SI message in the transmission period corresponding to the third SI message according to the ordering position of the third SI message in the scheduling information list and the transmission period corresponding to the third SI message along the tail-to-head direction;

that is, the method utilizes the transmission window to be determined along the tail of the transmission period to the head, so that the idle transmission window can be effectively utilized, and the conflict of the SI messages can be avoided as far as possible, so that the access network equipment can transmit more SI messages.

For example, if the third SI message is located in the q-th transmission window in the transmission period corresponding to the third SI message, the third SI message is transmitted in the q-th transmission window.

C12, determining a transmission window of the third SI message in the transmission period corresponding to the third SI message according to the ordering position of the third SI message in the scheduling information list and the transmission period corresponding to the third SI message along the direction from the head to the tail;

For example, if the third SI message is located at the q-th transmission window in the transmission period corresponding to the third SI message, the third SI message is transmitted.

Optionally, one implementation manner of the foregoing C11 may be:

determining a sending window of the third SI message in a sending period corresponding to the third SI message according to the ordering position of the third SI message in the scheduling information list and the sending period corresponding to the third SI message along the direction from the second position to the head according to the forward sequence or the reverse sequence of the SI message in the scheduling information list;

the second position is the last transmission window at the tail of the transmission period corresponding to the third SI message, or 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.

Here, it should be noted that the specific implementation manner of determining the sending window of the third SI message is:

when the third SI message is the h SI message in the positive sequence or the reverse sequence in the scheduling information list, determining that a sending window of the third SI message is the h sending window along the second position to the head direction in the sending period corresponding to the third SI message;

Wherein h is a positive integer.

For example, when the positive sequence is adopted and the offset value of the transmission window is not considered, if the third SI message is the 3 rd SI message 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 positive sequence is adopted and the offset value of the transmission window is considered (the offset value is 1 at this time, namely, one transmission window is offset), if the third SI message is the 3 rd 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.

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 4 th to last SI message in the scheduling information list, the transmission window of the third SI message is the fourth to 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 (the offset value is 2 at this time, namely, two transmission windows are offset), if the third SI message is the 4 th 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.

Optionally, it should also be noted that, in a 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 includes:

It should also be noted that the scheduling information list satisfies at least one of the following:

d11, the SI message in the scheduling information list is an SI message for non-positioning;

d12, the SI information in the scheduling information list is used for positioning;

d13, the scheduling information list is a list of a series target list;

it should be noted that, the target list includes at least one of the following:

d131, a list of one or more SI messages for non-positioning;

d132, a list of one or more SI messages for positioning.

It should be noted that, in the present embodiment of the present application, the scheduling info list in the existing SIB1 is a list of SI messages for non-positioning, and the existing list of SI messages for positioning is called a posschedulinginfo list, and, regardless of backward compatibility, such as 6G in the future, the scheduling information list in this embodiment may be a separate schedulinginfo list added with a null element, or a separate posschedulinginfo list.

For current 5G system information scheduling, backward compatibility needs to be considered, one possible way is to introduce a new scheduling information list, such as a list of SI messages for non-positioning that increases SI message placeholders, called schedulinglnfolist 3, an example of the structure of which is as follows:

the schedulingInfoList3 may include a plurality of elements, some of which correspond to null elements (i.e., choice null for schedulingInfo2-r17 structure) and others of which correspond to SI messages (i.e., choice schedulingInfo-r17 for schedulingInfo2-r17 structure).

The list of SI messages for positioning that adds SI message placeholders is called posSchedulingInfoList2, an example of the structure of which is as follows:

the new schedule information list is concatenated with the existing schedule information list (schedule info list or posschedule info list) to form a list (for convenience of description, it is a concatenated list), specifically, the new schedule information list may be placed at the back of the existing schedule information list to generate the concatenated list. Even a plurality of lists can be connected in series, and the position of the sending window is determined based on the position sequence in the list after the series connection, namely, one SI message is the x-th element in the list after the series connection, and then the x-th sending window or the x-th sending window of the sending period corresponding to the SI message is sent.

For example, when two lists generate a tandem list, it may be schedulingInfoList followed by schedulingInfoList3, or schedulingInfoList followed by schedulingInfoList2, or postschedulingInfoList followed by schedulingInfoList3, or postschedulingInfoList followed by postschedulingInfoList 2.

For example, when three lists generate a tandem list, it may be a tandem of postschedulingInfoList followed by schedulingInfoList and schedulingInfoList3, or a tandem of postschedulingInfoList followed by postschedulingInfoList and posschedulingInfoList2, or a tandem of postschedulingInfoList 3 and postschedulingInfoList 2.

For example, when four lists generate a tandem list, it may be schedulingInfoList followed by schedulingInfoList posSchedulingInfoList, schedulingInfoList and posschedulingInfoList2 in that order.

The specific application of this embodiment is specifically described below.

The specific application is seven,

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 SI8 to SI11 use the new mechanism, SI1 to SI7 are configured in the schedulinglnfolist, SI8 to SI11 are configured in the schedulinglnfolist 3, according to the existing mechanism, the transmission window of SI-9 and SI-10 collides with the occurrence window of the next period of SI-1 and SI-2, in order to avoid the collision, the second and third elements of the schedulinglnfolist 3 may be set as null elements, and SI-9 and subsequent SI messages are sequentially moved backward, and the configuration in the schedulinglnfolist 3 is as shown in the table:

Table 6 order of SI messages in scheduling information table 3

Then schedulingInfoList is concatenated with schedulingInfoList3 as shown in Table 7:

table 7 sequence comparison table of SI messages in scheduling information after concatenation

When the positive sequence 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 fig. 18.
