Abstract

The embodiment of the application provides a system information transmission method, equipment and a system. The method comprises the following steps: the network device instructs the terminal device to receive the first system information and simultaneously transmits configuration information for transmission of the first system information, for example, scheduling information of the first system information or time domain position information of the scheduling information of the first system information, to the terminal device, so that the terminal device can receive the first system information according to the configuration information transmitted by the network device while instructing the terminal device to receive the first system information. Or the terminal device may receive the first system information according to the transmission configuration information acquired before, without transmitting the configuration information for transmission of the first system information while the network device instructs the terminal device to receive the first system information.

Description

Technical Field

The present application relates to the field of communications, and in particular, to a method, an apparatus, and a system for transmitting system information.

Background

In a mobile communication network, paging of a terminal device by the network is generally classified into two types, one type is used for notifying the terminal device to perform random access, so that the terminal device enters a radio resource control (radio resource control, RRC) connection state for subsequent data communication; another class is used to inform the terminal device of the reception of system information (system information, SI) by short messages.

At present, when the terminal equipment determines to receive system information, firstly, the terminal equipment receives a system information block (system information block, SIB) 1, then obtains scheduling information of downlink control information (downlink control information, DCI) from the SIB1, obtains DCI according to the scheduling information of the DCI, and finally receives the system information according to the DCI.

However, the delay of receiving the system information by using the above scheme is long, particularly, when the terminal device fails to receive the SIB1, it is necessary to wait for the next period to re-receive the SIB1 until the SIB1 is received successfully, and then the system information is received according to the DCI, which further increases the receiving delay of the system information.

Detailed Description

In order to facilitate understanding of the technical solutions of the embodiments of the present application, a brief description of related technologies or terms of the present application is given below.

A first, radio resource control (radio resource control, RRC) state.

Taking a new radio, NR, system as an example, in NR, the RRC states of the terminal device include the following three states: the transitions of the RRC CONNECTED state (rrc_connected), the RRC deactivated state (rrc_inactive), and the RRC IDLE state (rrc_idle) are shown in fig. 1.

When the terminal equipment is in an RRC connection state, the terminal equipment, the access network equipment and the core network equipment are connected, and when data arrives at the network, the data can be directly transmitted to the terminal equipment; when the terminal equipment is in RRC deactivation dynamic state, a link is established between the terminal equipment and the access network equipment as well as between the access network equipment, but the link between the terminal equipment and the access network equipment is released, at the moment, the terminal equipment and the access network equipment store the context of the terminal equipment, and when data needs to be transmitted, the access network equipment can quickly recover the link; when the terminal equipment is in an RRC idle state, no link is established between the terminal equipment and the access network equipment and between the terminal equipment and the core network equipment, and when data needs to be transmitted, the link from the terminal equipment to the access network equipment and the core network equipment needs to be established.

It is to be understood that the above RRC states are only examples and should not be construed as limiting the present application in any way. The application does not exclude that other possible designations are defined in future protocols instead of existing designations, but with the same or similar properties, or that other states may occur.

And secondly, paging the terminal equipment by the network.

In a mobile communication network (e.g., long term evolution (longterm evolution, LTE) or NR), paging of a terminal device by the network is generally classified into two types, one type is used to notify the terminal device in an RRC idle state to perform random access through a Paging (Paging) message, so that the terminal device enters an RRC connected state for subsequent data communication; another type is used to inform the terminal device of receiving system information through a short message.

Thus, in the embodiment of the present application, the Paging (Paging) message refers to a message for sending a call request to a terminal device in an RRC idle state, and notifying the terminal device to perform random access; the short message refers to a message for informing the terminal device of receiving system information.

In the embodiment of the application, the system information comprises public safety alarm information borne on SIB6, SIB7 or SIB8, or comprises information borne on other SIBs except SIB6, SIB7 and SIB 8.

It is understood that "receiving system information" may also be understood as "receiving SIBs carrying the system information" and that the two may be interchanged.

Wherein the public safety warning information comprises earthquake tsunami warning system (earthquake and tsunami WARNING SYSTEM, ETWS) information and/or business mobile alert service (commercial mobile ALERT SERVICE, CMAS) information. The ETWS includes ETWS main (primary) information carried on SIB6 and/or ETWS auxiliary (secondary) information carried on SIB 7; CMAS is carried over SIB 8.

And thirdly, scheduling short messages and paging messages.

In the existing standard protocol, whether the DCI includes a short message or not and whether the DCI includes scheduling information of a paging message or not are indicated by paging DCI (i.e., PAGING DCI).

Wherein, the paging DCI includes the following partial fields:

Short message indication (short messages indicator) field: the size is 2 bits (bit) and the content is defined in table 1 below. Wherein, the state '00' is reserved and not used, namely, when the short message indicates '00', the state is invalid.

TABLE 1

bitfield	Short message indication
		00	Reserved, not in use
01	The DCI includes scheduling information of a paging message, and the DCI does not include a short message.
		10	The DCI does not include scheduling information of a paging message and the DCI includes a short message.
11	The DCI includes scheduling information of a paging message, and the DCI further includes a short message.

Short message content (short message) field: the size is 8bits and the content definition is given in Table 2 below. If the above-mentioned short message indication field indicates that the DCI includes scheduling information of a paging message and does not include a short message, the field is invalid (reserved).

In the embodiment of the present application, the field invalidation refers to that the field/state does not carry information, or the terminal device or the network device does not parse the field, which is generally described herein, and the following embodiments are not repeated.

TABLE 2

Wherein the BCCH represents a broadcast control channel (broadcast control channel, BCCH).

When the 1 st bit of the short message content field has a value of "1", it indicates that the system information carried in the BCCH is modified, which can be also understood as: indicating that other SIBs than SIB6, SIB7 and SIB8 are updated, but the bit cannot indicate which SIBs the updated SIBs are specific to; when the value of the 2 nd bit of the short message content field is "1", it indicates that there is ETWS and/or CMAS information, which can also be understood as: indicating that one or more of SIB6, SIB7 and SIB8 are updated, as well as the bit being unable to indicate which SIBs of SIB6, SIB7, SIB8 are specifically.

Frequency domain resource indication field: the size is determined according to the maximum number of frequency domain resources, for example, the size can satisfy the formula: Wherein/> The maximum number of resources in the frequency domain or the number of resources in the frequency domain which can be allocated. If the short message indication field indicates that the DCI does not include the scheduling information of the paging message, the field is invalid.

Time domain resource indication field: the size is 4bits. If the short message indication field indicates that the DCI does not include the scheduling information of the paging message, the field is invalid.

Modulation coding scheme indication field: the size is 5bits. If the short message indication field indicates that the DCI does not include the scheduling information of the paging message, the field is invalid.

Transport block scaling factor field: the size is 2bits. If the short message indication field indicates that the DCI does not include the scheduling information of the paging message, the field is invalid.

Reserved bits: the size is 6bits.

Fourth, paging occasion.

The terminal device may periodically receive the paging DCI, where the period is a paging period. The moment when the terminal device specifically receives the DCI is called Paging Occasion (PO), and is determined by the network device and configured to the terminal device.

For example, as shown in fig. 2, a paging cycle may include a plurality of paging frames (PAGING FRAME, PF), where each paging frame includes a plurality of POs, and one PO corresponds to one or more terminal devices, that is, paging information of a plurality of terminal devices may be carried in a paging message scheduled by paging DCI transmitted in one PO.

Fifth, the receiving flow of the public safety warning information is existed.

As shown in fig. 3a, the receiving process of the public safety warning information specified by the existing protocol may include the following steps:

S301, receiving paging DCI by the terminal equipment.

The terminal device may determine a PO according to the configuration of the network device, detect a physical downlink control channel (physical downlink control channel, PDCCH) on the PO, and when detecting the PDCCH, parse paging DCI carried on the PDDCH.

The terminal device may determine whether the short message indication field in the DCI indicates that the paging DCI includes a short message, and when it is determined that the paging DCI includes a short message (e.g., the value of the short message indication field is "10" or "11"), it is further determined whether the short message content field in the paging DCI indicates that there is ETWS and/or CMAS information, and when it is determined that the short message indicates that there is ETWS and/or CMAS information (e.g., the value of the 2 nd bit of the short message content field is "1"), perform step S302 described below.

S302, the terminal equipment acquires system information scheduling information (SI scheduling information, SI-SchedulingInfo).

The terminal device may receive SIB1 from the network device, acquire the SI-SchedulingInfo from the SIB1, and execute step S303 described below.

The partial elements included in this SI-SchedulingInfo are as follows:

Scheduling information list (scheduling info list): scheduling information defining one or more DCIs, each of the one or more DCIs scheduling one system message (SI-message), each system message may include 1 or more SIBs. I.e., the scheduling information list includes scheduling information (SchedulingInfo) of one or more DCIs.

System information window length (si-WindowLength): the system message detection window length is defined, and the value of the system message detection window length can be one of { s5, s10, s20, s40, s80, s160, s320, s640, s1280}, s represents a subframe, and the time unit can be 1 millisecond, for example, s5 represents 5 milliseconds.

The partial cells included in the scheduling information of the DCI are as follows:

si-BroadcastStatus: indicating whether the system message is a broadcast message;

si-Periodicity: the broadcasting period of the DCI representing the scheduling system message may take one of { rf8, rf16, rf32, rf64, rf128, rf256, rf512} as a value, where rf represents a radio frame and the time unit may be 10 ms, for example, rf8 represents 80ms;

For example, taking 7 SIBs broadcasted in total, SIB2, SIB3, SIB4, SIB5, SIB6 and SIB7, respectively, the SI-SchedulingInfo can be as follows:

Accordingly, in this case, the detection schemes of DCI1 and DCI2 may be as shown in fig. 3b, and the terminal device may detect DCI1 in time window 1 and DCI2 in time window 2 of each period according to the SI-SchedulingInfo.

S303, the terminal equipment receives DCI for scheduling public safety warning information according to SI-SchedulingInfo.

I.e. the terminal device receives DCI according to the configuration information in SI-SchedulingInfo.

S304, the terminal equipment receives the public safety warning information according to the DCI for dispatching the public safety warning information.

For example, the terminal device receives public safety warning information on the DCI scheduled time-frequency resource.

So far, the receiving flow of the public safety warning information is ended. The process of receiving SIB other than SIB6, SIB7 and SIB8 is similar to that shown in FIG. 3a, and will not be repeated here.

The structure of pagingRecord may be exemplified as follows:

Wherein, "indicates pagingRecord is scalable, i.e., pagingRecord may include other cells in addition to ue-Identity and ACCESSTYPE.

By way of example, the structure of the ue-Identity may be as follows:

Wherein TMSI represents a temporary mobile subscriber identity (temporary mobile subscriber identity), I represents RRC deactivation dynamics (rrc_inactive), and RNTI represents a radio network temporary identity (radio network temporary identifier). "." means that the ue-Identity is scalable, i.e. that the ue-Identity may include other cells in addition to the ng-5G-S-TMSI and fullI-RNTI.

Currently, in the existing system information receiving process, before receiving system information, a terminal device needs to receive SIB1 to obtain SI-SchedulingInfo, then receives scheduling information of the system information according to SI-SchedulingInfo, and then receives the system information according to the scheduling information of the system information, which increases the receiving delay of the system information. In particular, as shown in fig. 7, when SIB1 fails to be received, it is necessary to wait for the next period to re-receive SIB1 until SIB1 is received successfully and then receive system information according to scheduling information, which further increases the delay of receiving system information.

Based on this, an embodiment of the present application provides a system information transmission method, and the system information transmission method provided by the embodiment of the present application will be specifically described with reference to fig. 1 to 7.

It should be noted that, in the following embodiments of the present application, names of messages (or information) or names of parameters in messages (or information) are merely examples, and may be other names in specific implementations, which are not limited in particular by the embodiments of the present application.

As shown in fig. 8a, a system information transmission method according to an embodiment of the present application includes the following steps:

s801, the network equipment sends first information to the terminal equipment. Accordingly, the terminal device receives the first information from the network device.

The first information comprises first indication information, and the first indication information indicates the terminal equipment to receive first system information.

In the embodiment of the present application, the first indication information is used to instruct the terminal device to receive the first system information, which can also be understood as: the first indication information is used for indicating that the first system information is updated.

Optionally, the first information may be a first DCI, and a cyclic redundancy check (cyclic redundancy check, CRC) of the first DCI is scrambled by a paging radio network temporary identity (paging radio network temporary identifier, P-RNTI); or the first information may be a first DCI, and a CRC of the first DCI is scrambled by a random access radio network temporary identity (random access radio network temporary identifier, RA-RNTI).

Optionally, in different implementation scenarios of the embodiment of the present application, there may be multiple implementations of the first information including the first indication information, which are exemplary:

in the first mode, the first information includes short message indication information, and when the bit state of the short message indication information is the first state, the short message indication information is the first indication information.

Optionally, the bit state of the short message indication information may have other bit states besides the first state to indicate whether the first information includes the scheduling information of the paging message and whether the first information includes the short message, where the relevant description of the short message may refer to the above table 2, and will not be described herein.

Illustratively, taking the example that the short message indication information is 2 bits, the content definition of the different status indications of the short message indication information can be as follows in table 3.

TABLE 3 Table 3

Bit state	Short message indication
		First state (00)	Indicating to receive first system information
Second state (01)	The first information includes scheduling information of the paging message and does not include the short message.
		Third state (10)	The first information does not include scheduling information of the paging message and includes a short message.
Fourth state (11)	The first information includes scheduling information of a paging message and also includes a short message.

It may be understood that the number of bits representing the short message indication information is different, and the first state of the short message indication information is also different, for example, when the short message indication information is 3 bits, the first state of the short message indication information may be "111", and the number of bits of the short message indication information is not specifically limited in the embodiment of the present application.

In the second mode, the first information includes short message indication information, and when the bit state of the short message indication information is the first state, the first information includes the first indication information.

That is, whether the first information includes the first indication information is indicated by the short message indication information, and the first information includes the first indication information when the bit state of the short message indication information is the first state.

Illustratively, taking the example that the short message indication information is 2 bits, the content definition of the different status indication of the short message indication information can be as follows in table 4.

TABLE 4 Table 4

In a third mode, the first information includes a short message, the first indication information is an nth bit in the short message, and N is a positive integer.

Optionally, in the third mode, the first information may further include short message indication information, and the short message indication information may indicate that the first information includes a short message.

Alternatively, when the content of the short message is defined as shown in table 2, N may be 1 or 2.

S802, the network equipment sends first system information to the terminal equipment. Accordingly, the terminal device receives the first system information from the network device.

After receiving the first indication information, the terminal device may receive first system information according to second information, where the second information is information included in the first information, and the second information includes configuration information used for transmission of the first system information.

Or after the terminal device receives the first indication information, the first system information may be received according to third information, where the third information is configuration information for transmitting the first system information, which is obtained by the terminal device before the terminal device receives the first information, and may be obtained by DCI or obtained by SIB1 by the terminal device, or the third information is configuration information for transmitting the first system information, which is sent by the network device or other terminal devices to the terminal device before the network device sends the first information, or the third information is configuration information for transmitting the first system information, which is stored by the terminal device.

Or after receiving the first indication information, the terminal device may receive the first system information according to fourth information, where the fourth information is information scheduled by the first information, and the fourth information includes configuration information used for transmitting the first system information. In case the first information is the first DCI, the fourth information of the first information schedule may be information included in the paging message.

That is, after the terminal device receives the first indication information, the first system information may be received according to the second information or the third information or the fourth information, and for the network device, it may be understood that the first indication information is used to instruct the terminal device to receive the first system information according to the second information or the third information or the fourth information.

In the embodiment of the present application, the configuration information may be scheduling information of a physical layer and/or transmission parameters configured by a higher layer, where the scheduling information of the physical layer may be time-frequency resource information carried by DCI, and the transmission parameters configured by the higher layer may be a transmission period, a time window, and so on.

Optionally, the type indication information indicates a SIB included in the first system information. For example, the type indication information may indicate whether M SIBs are updated, and the SIBs having the update among the M SIBs are SIBs included in the first system information.

For example, taking the example that the type indication information may indicate whether one or more of SIB6, SIB7 and SIB8 is updated, the type indication information may indicate whether SIB6, SIB7 and SIB8 are updated by using a 3-bit bitmap (bitmap), where the 3 bits are in one-to-one correspondence with SIB6, SIB7 and SIB 8; or 2 bits may be used to indicate whether SIB6, SIB7, SIB8 are updated, e.g., SIB6 and SIB7 are ETWS messages, one bit is used to indicate whether they are updated, and another bit is used for CMAS to indicate whether they are updated.

For the second information:

optionally, in different implementation scenarios of the embodiment of the present application, the configuration information included in the second information for the transmission of the first system information may also be different.

In a possible implementation manner, the configuration information for the transmission of the first system information included in the second information is first scheduling information, and the first scheduling information is scheduling information of the first system information. I.e. the second information comprises scheduling information of the first system information scheduling time domain resources and/or frequency domain resources in which the first system information is transmitted.

That is, in this implementation manner, the processing flow of the terminal device in the embodiment of the present application may be as shown in fig. 8 c:

S801, the terminal equipment receives first information.

S803, according to the type indication information and/or the range indication information, the first system information is determined to be received.

Step S803 is an optional step, and step S801 and step S803 may refer to the relevant description in the embodiment shown in fig. 8a or fig. 8 b.

optionally, when the bit state of the short message indication information included in the first information is the first state, or the short message indication information indicates that the first information does not include the scheduling information of the paging message, the one or more pieces of information may multiplex a field originally designed for scheduling of the paging message in the first information. Based on the scheme, fields originally designed for scheduling of paging messages can be multiplexed, so that the format of the existing DCI is not changed, and backward compatibility is better realized.

Based on the possible implementation manner, since the scheduling information of the first system information is carried in the first information, the terminal equipment can directly receive the first system information according to the scheduling information without receiving the SIB1, and then receive the first system information according to the SIB1, so that the receiving time delay of the first system information can be reduced.

In another possible implementation, the second information includes configuration information for transmission of the first system information, and the configuration information is used to configure a time domain position of the first scheduling information.

That is, the terminal device may receive the first scheduling information according to the configuration information for the transmission of the first system information, and receive the first system information according to the first scheduling information, i.e., on the time domain resources and/or the frequency domain resources scheduled by the first scheduling information. That is, in this implementation manner, the processing flow of the terminal device in the embodiment of the present application may be as shown in fig. 8 d:

S801, the terminal equipment receives first information.

Step S802 may include the following steps:

Optionally, the configuration information for the first system information transmission may include one or more of the following: period information, time window indication information, or time domain resource indication information is transmitted, which may indicate the length of the time window and/or an identification of the time window.

The transmission period information indicates a transmission period of the first scheduling information, and the time unit of the transmission period information may be, for example, radio frames, that is, the transmission period of the first scheduling information may be r radio frames, where r is a positive integer. The length of the time window represents a time range when the first scheduling information is detected in the transmission period of the first scheduling information, and the time unit of the time window may be, for example, subframes, and the length of the time window may be s subframes, where s is a positive integer; the identification of the time window indicates the time window carrying the first scheduling information. The time domain resource indication information indicates a starting time domain resource position, a time domain length, etc. of the first scheduling information transmission. The starting time domain resource location may be a time slot, a symbol, a subframe, a frame, a mini-slot, a sub-slot, etc. in which the first scheduling information starts to be transmitted.

It is to be understood that the length of the above time window or the time unit of the period may be a time slot, a symbol, a subframe, a mini-slot, a sub-slot, etc., which is not limited in particular in the embodiment of the present application.

Optionally, in this implementation manner, the content indicated by the short message indication information included in the first information is different, and the fields occupied by the one or more items of information in the first information are also different. By way of example, there may be two cases:

in the first case, the short message indication information indicates that the first information includes a short message, and the first information does not include scheduling information of a paging message.

In this case, one or more of the transmission period information, the time window indication information, the time domain resource indication information may multiplex a field originally designed for scheduling information of the paging message in the first information, and the field originally designed for scheduling information of the paging message may include one or more of a frequency domain resource indication field, a time domain resource indication field, a modulation and coding scheme indication field, a transport block scaling factor field, or a reserved bit. Alternatively, in this case, a field designed for scheduling information of the paging message is not included in the first information, and a field indicating configuration information for transmission of the first system information is included.

When the configuration information for the transmission of the first system information may include transmission period information and/or time window indication information, the first information may include a period field, a window length field, and an identification field for indicating the transmission period information, the length of the time window, and the identification of the time window, respectively.

Alternatively, if the period field, the window length field, and the identification field are all 3 bits in size, the content definition of the period field may be as shown in table 5, the content definition of the window length field may be as shown in table 6, and the content definition of the identification field may be as shown in table 7.

It may be understood that when the configuration information for the first system information transmission includes other information, for example, when the time domain resource indication information is included in the first information, the time domain resource indication field may also be included in the first information, and the specific implementation may refer to the relevant description of the period field, the window length field, and the identification field, which are not described herein again.

In the second case, the short message indication information indicates that the first information includes a short message, and the first information includes scheduling information of a paging message.

In this case, one or more of the transmission period information, the time window indication information, and the time domain resource indication information may multiplex the original reserved bits in the first information. Alternatively, in this case, the reserved bits are not included in the first information, and a field indicating configuration information for transmission of the first system information is included.

Based on the possible implementation manner, because the time domain position information of the first scheduling information is carried in the first information, when the scheduling information of the first system information is too large to be carried by the first information, the terminal equipment can gradually receive the first system information according to the time domain position information of the first scheduling information, so that the receiving time delay of the first system information is reduced.

For the third information:

Optionally, in the embodiment of the present application, the third information may be first scheduling information, or may be information for configuring a time domain position of the first scheduling information. The first scheduling information and the information for configuring the time domain position of the first scheduling information may refer to the related description in the second information, which is not described herein.

Optionally, the third information may be configuration information for transmission of the first system information, which is stored by the terminal device and is used when the first system information is received last time; or the configuration information for the current transmission of the first system information, which is sent to the terminal device by the network device before the first information is sent.

For the fourth information:

Optionally, in the embodiment of the present application, the fourth information scheduled by the first information may be information included in the paging message, that is, the first information includes scheduling information of the paging message, where the paging message scheduled by the scheduling information of the paging message includes the fourth information, and the fourth information includes configuration information for transmission of the first system information. In this case, it can be understood that the short message indication information included in the first information indicates that the first information includes scheduling information of the paging message and also includes the short message.

Optionally, in different implementation scenarios of the embodiment of the present application, the configuration information included in the fourth information for the transmission of the first system information may also be different.

In a possible implementation manner, the configuration information for the transmission of the first system information included in the fourth information is first scheduling information, and the first scheduling information is scheduling information of the first system information. That is, the fourth information includes scheduling information of the first system information, which schedules time domain resources and/or frequency domain resources in which the first system information is transmitted.

That is, in this implementation manner, the processing flow of the terminal device in the embodiment of the present application may be as shown in fig. 8 e:

S801, the terminal equipment receives first information.

Step S802 may include the following steps:

S8021c, the terminal equipment acquires fourth information according to the first information.

Optionally, after receiving the first information, the terminal device may receive the paging message according to the scheduling information of the paging message included in the first information, and then parse the paging message to obtain fourth information in the paging message.

S8022c, the terminal equipment acquires the first scheduling information according to the fourth information.

Optionally, after the terminal device obtains the fourth information, the first scheduling information included in the fourth information may be obtained according to a position of the first scheduling information in the fourth information.

S8023c, the terminal equipment receives the first system information according to the first scheduling information.

Optionally, in this implementation, the configuration information for the first system information transmission may include one or more of: frequency domain resource indication information, time domain resource indication information, modulation coding mode indication information, transmission block scaling factor information, beam information, power information and subcarrier spacing information.

Alternatively, in this case, the fourth information including the first scheduling information may be: the fourth information includes a first field including first scheduling information. For example, a specific structure (e.g., pagingRecord) may be included in the fourth information, and a first field may be included in the specific structure and the first scheduling information may be included in the first field.

Alternatively, the first field may exist in two cases:

in case one, the first field may be a terminal device identification field.

When the structure is pagingRecord, the existing terminal equipment identification field is multiplexed to transmit the first scheduling information. It will be appreciated that the terminal device identification field is not used to indicate a certain terminal device in the system at this time.

In this implementation manner, optionally, if the first scheduling information does not occupy all bits of the terminal device identification field, the terminal device identification field may further include third indication information, where the third indication information is used to indicate a position of the first scheduling information in the terminal device identification field, for example, the third indication information indicates a starting bit position of the first scheduling information in the terminal device identification field and/or a length of the first scheduling information, or the third indication information indicates that the first scheduling information is located in a high bit or a low bit of the terminal device identification field.

Based on the scheme, the position of the first scheduling information in the terminal equipment identification field can be indicated by the third indicating information, so that the terminal equipment can accurately analyze the terminal equipment identification field, the field is prevented from being analyzed into the identification of certain terminal equipment, and the terminal equipment corresponding to the identification can analyze the information in the structural body where the field is located into the paging information of the terminal equipment.

In case two, when the specific structure is pagingRecord, the first field may be an extension field in the specific structure, except for the terminal device identification field and the access type field.

At this time, in order to distinguish the first scheduling information from the paging information, the terminal device indicated by the terminal device identification field of the specific structure is a terminal device that does not exist in the system.

It is understood that in this implementation, the first field may also have other names, which embodiments of the present application do not specifically limit. Illustratively, taking the specific structure as pagingRecord and the name of the first field as SchedulingInfo as an example, the structure of the specific structure may be as follows:

Alternatively, in this case, the fourth information may further include fourth indication information for indicating that the first scheduling information is included in the fourth information. Based on the scheme, the terminal equipment can be instructed to receive the first system information according to the first scheduling information in the fourth information, and the public safety warning information is received according to the SIB1 after the SIB1 is not required to be received according to the existing flow.

Based on the possible implementation manner, the fourth information included in the paging message scheduled by the first information includes the first scheduling information, so that the first information can schedule the paging message, and the scheduling information of the first system information is transmitted in the paging message, so that the terminal device can receive the first system information according to the first scheduling information in the paging message, and further reduce the receiving delay of the first system information.

In another possible implementation, the fourth information includes configuration information for the transmission of the first system information, and the configuration information is used to configure a time domain position of the first scheduling information.

That is, the terminal device may receive the first scheduling information according to the configuration information for the transmission of the first system information, and receive the first system information according to the first scheduling information, i.e., on the time domain resources and/or the frequency domain resources scheduled by the first scheduling information. That is, in this implementation manner, the processing flow of the terminal device in the embodiment of the present application may be as shown in fig. 8 f:

S801, the terminal equipment receives first information.

Step S802 may include the following steps:

s8021d, the terminal equipment acquires fourth information according to the first information.

S8022d, the terminal equipment acquires the time domain position information of the first scheduling information according to the fourth information.

Optionally, after the terminal device obtains the fourth information, the terminal device may obtain the time domain location information of the first scheduling information included in the fourth information according to the location of the time domain location information of the first scheduling information in the fourth information.

S8023d, the terminal equipment acquires the first scheduling information according to the time domain position information of the first scheduling information.

S8024d, the terminal equipment receives the first system information according to the first scheduling information.

Optionally, in this case, the manner in which the fourth information includes the configuration information for the transmission of the first system information may be referred to as the manner in which the fourth information includes the first scheduling information in the previous possible implementation, which is not described herein.

Optionally, in an implementation scenario of the embodiment of the present application, the fourth information of the first information schedule may include first system information, that is, the first information includes scheduling information of a paging message, where the paging message scheduled by the scheduling information of the paging message includes the fourth information, and the fourth information includes the first system information. In this case, it can be understood that the short message indication information included in the first information indicates that the first information includes scheduling information of the paging message and also includes the short message.

Alternatively, in this scenario, a specific structure (e.g., pagingRecord) may be included in the fourth information, and the first system information may be included in the specific structure.

Optionally, in this scenario, the fourth information may further include fifth indicating information, where the fifth indicating information is used to indicate that the paging message includes the first system information. Based on the scheme, the terminal equipment can be instructed to receive the first system information in the paging message without receiving the SIB1 according to the existing flow, and then receiving the first system information according to the SIB 1.

Optionally, in this scenario, the first information may further include sixth indication information, where the sixth indication information is used to indicate a location of the first system information in the paging message. Based on the scheme, the terminal equipment can quickly receive the first system information in the paging message according to the sixth indication information without traversing each structure body in the paging message, so that the receiving time delay of the first system information is further reduced. The sixth indication information may be, for example, an identification of a structure (e.g., pagingRecord) where the first system information is located in the paging message.

Based on the possible implementation manner, because the time domain position information of the first scheduling information is carried in the paging message, when the scheduling information of the first system information is too large to be carried by the paging message, the terminal equipment can gradually receive the first system information according to the time domain position information of the first scheduling information included in the paging message, so that the receiving time delay of the first system information is reduced.

In summary, the embodiment of the present application may provide six manners of receiving the first system information, where the six manners may form a set of receiving manners of the first system information:

The first mode is to receive first system information according to first scheduling information included in the second information;

The second mode is to receive the first system information according to the information of the time domain position used for configuring the first scheduling information included in the second information;

Receiving first system information according to first scheduling information included in fourth information;

Fourth, receiving first system information according to information, included in the fourth information, of a time domain position used for configuring the first scheduling information;

a fifth mode is that first system information is received according to third information acquired by the terminal equipment before the first information is received;

and a sixth mode, receiving the first system information according to the SIB 1.

Optionally, in this scenario, when the bit state of the first indication information in step S801 is the first state, the terminal device may be instructed to receive the first system information in the first manner, and correspondingly, in step S802, the terminal device receives the first system information in the first manner; when the bit state of the first indication information is the second state, the terminal device may be instructed to receive the first system information in the second manner, and correspondingly, in step S802, the terminal device receives the first system information in the second manner.

Optionally, when the bit of the second indication information is in the first state, the terminal device may be instructed to receive the first system information in the first mode, and correspondingly, in step S802, the terminal device receives the first system information in the first mode; when the bit state of the second indication information is the second state, the terminal device may be instructed to receive the first system information in the second manner, and correspondingly, in step S802, the terminal device receives the first system information in the second manner.

The first mode is one of the six modes, and the second mode is a mode different from the first mode.

The embodiment of the application also provides a system information transmission method, which comprises the following steps:

Step 1, the network equipment sends first information to the terminal equipment, and correspondingly, the terminal equipment receives the first information from the network equipment.

Alternatively, the terminal device may determine to receive the first system information according to the first information.

And step 2, the network equipment sends the first system information to the terminal equipment. Accordingly, the terminal device receives the first system information from the network device.

Optionally, the first information includes first indication information.

In a possible implementation, the first indication information can be used to indicate that the terminal device receives SIB1, and that the terminal device does not need to receive one or more of SIB 1. For example, when the bit state of the first indication information is the first state, and the terminal device is instructed to receive SIB1, the terminal device may receive SIB1 based on the indication of the first indication information, and then receive the first system information according to SIB 1; and when the bit state of the first indication information is the second state, indicating that the terminal equipment does not need to receive the SIB1, and correspondingly, receiving the first system information according to the third information by the terminal equipment.

Alternatively, the terminal device is instructed to receive SIB1, which can also be understood as: instructing the terminal device to monitor a physical downlink control channel (physical down link control channel, PDCCH) carrying SIB 1; indicating that the terminal device does not need to receive SIB1 can also be understood as: the indication terminal device does not need to monitor (monitor) the PDCCH carrying SIB 1. That is, the first indication information can be used to instruct the terminal device to monitor the PDCCH carrying SIB1, and the terminal device does not need to monitor one or more of the PDCCHs carrying SIB 1.

Based on the scheme, the terminal equipment can determine whether to receive SIB1 or monitor the scheduling information carrying SIB1 according to the first indication information, and can reduce the frequency of the terminal equipment to receive SIB1, thereby saving the power consumption overhead of the terminal equipment, and reducing the time delay of the terminal equipment to receive the first system information when the SIB1 is not required to be received.

In another possible implementation, the first indication information can be used to indicate that the first information includes one or more of configuration information related to transmission of the first system information, and that the first information does not include configuration information related to transmission of the first system information. For example, when the bit state of the first indication information is the first state, the first indication information includes configuration information related to transmission of the first system information, and correspondingly, the terminal device receives the first system information according to the second information or the fourth information; and when the bit state of the first indication information is the second state, indicating that the first information does not comprise the configuration information related to the transmission of the first system information, and correspondingly, receiving the first system information by the terminal equipment according to the third information.

In yet another possible implementation, the first indication information can be used to indicate one or more of an update of configuration information for the first system information transmission, and an un-update of configuration information for the first system information transmission. For example, when the bit state of the first indication information is the first state, the configuration information for the transmission of the first system information is indicated to be updated, and correspondingly, the terminal equipment receives the first system information according to the second information or the fourth information; and when the bit state of the first indication information is the second state, indicating that the configuration information for the transmission of the first system information is not updated, and correspondingly, the terminal equipment receives the first system information according to the third information.

In yet another possible implementation manner, the first indication information can be used to instruct the terminal device to receive SIB1, where the first information includes one or more of configuration information related to the transmission of the first system information, and configuration information of the transmission of the first system information is not updated. For example, when the bit state of the first indication information is the first state, the configuration information for the first system information transmission is indicated to be updated in SIB1, and accordingly, the terminal device receives SIB1 and then receives the first system information according to SIB 1; when the bit state of the first indication information is the second state, the configuration information for the transmission of the first system information is indicated to be updated in the second information included in the first information or updated in the fourth information scheduled by the first information, and the terminal equipment correspondingly receives the first system information according to the second information or the fourth information; and when the bit state of the first indication information is a third state, indicating that the configuration information for the transmission of the first system information is not updated, and correspondingly, the terminal equipment receives the first system information according to the third information.

Based on the scheme, the terminal equipment can determine to receive the first system information according to the second information, the third information or the fourth information according to the first indication information, and the time delay of the terminal equipment for receiving the first system information can be reduced.
