Description

System information transmission method and device

Technical field

The present application relates to the field of communications technologies, and in particular, to a system information transmission method and apparatus. Background technique

System information is mainly used to characterize related parameters of a wireless cell, and is added to the system information block.

In the SIB (System Information Block), the system information is sent to the user equipment (User Equipment, UE) in the cell by the base station on the air interface in a periodic broadcast manner, so that the UE determines the station according to the received system information. The parameter settings used when leaving the cell.

Since the broadcast channel must transmit data according to a fixed-size transport block, in order to ensure that the size of the system information block satisfies the requirements of the broadcast channel, the network side needs to segment and/or cascade the system information block according to the requirements of the broadcast channel. A transport block that meets the requirements. A transport block may contain multiple different types of system information blocks, called system information sub-blocks. In order to correctly characterize the content of a transport block, in addition to the data, the transport block also contains header information of some system information sub-blocks. For example, the system information block type (SIB type) occupies 5 bits, and the total number of partition blocks (SEG_COUNT) Or the segment index occupies 4 bits. For a 246-bit transport block, the header information occupies part of the bit of the transport block, resulting in less valid data contained in one transport block, and data transmission efficiency low. In particular, when the system information block is divided into a plurality of transport blocks, part of the header information is included in each transport block, so that the problem of low data transmission efficiency is more obvious.

With the evolution of communication systems, more and more information needs to be broadcast to the UE in the form of system information blocks. If the existing system information block broadcast mode is adopted, the less effective information carried by the broadcast channel, the more header information This leads to a longer SIB broadcast cycle. Since the UE determines the parameter setting of the camping cell according to the SIB broadcasted by the base station, if the SIB broadcast period is extended, the access delay of the UE is also extended accordingly, which inevitably reduces the user experience.

The embodiments of the present invention are further described in detail below in conjunction with the drawings and embodiments.

Referring to FIG. 1, a flowchart of Embodiment 1 of a system information transmission method according to an embodiment of the present invention is shown, where the method includes:

Step 101: The base station selects at least one type of system information block as a to-be-processed system information block according to a preset condition.

Step 102: The base station performs segmentation and/or concatenation processing on the to-be-processed system information block according to a transmission requirement of a broadcast channel to obtain a transport block, where the transport block includes at least one type of system information sub-block. The system information sub-block includes: a header domain and a data domain.

With the evolution of the communication system, different versions of the communication system include different types of system information blocks. The following is an example of the WCDMA (Wideband Code Division Multiple Access) communication system R5 version. . In the R5 version of the WCDMA system, regardless of the extension of each system information (for example: SIBl lbis, etc.), there are a total of 18 types of System Information Blocks (SIBs), which are identified as SIB1 to SIB18, respectively. The SIB periodically broadcasts on the BCCH channel. The SIB includes public information of the access network and the core network. The information of the core network includes information such as carrier information and authentication. The information of the access network includes a location registration area, a cell, a public channel, and Cell selection/reselection information, etc. These messages are convenient for the user to understand the configuration of the cell, determine whether the terminal can camp and whether a normal call can be initiated.

When the user equipment selects the appropriate cell for the first time after booting, it broadcasts from the broadcast channel (Broadcast)

Channel, BCH) reads all system information of the cell; system information can be divided into a master information block (MIB), a scheduling block (SB), and a system information block (SIB), and the MIB provides the SIB. Referencing and scheduling messages, and providing reference and scheduling messages of one or two SBs, the SB also provides reference and scheduling information of the SIB, and the scheduling information of each SIB can only be included in the MIB or SB, and the scheduling information is placed in the MIB. When not, the SB can be used as a supplement to continue to schedule information.

The system stipulates that a system information is broadcast on the BCH at a fixed period. The length of the system information must match the size of a BCH transport block. To this end, some system information blocks need to be split or cascaded; Example: Main Public Control The Primary Common Control Physical Channel (P-CCPCH) specifies that the fixed period is 20ms and the fixed transport block size is 246bits. In order to meet the transmission requirements of the channel, some SIBs must be split and/or cascaded.

For example: If the SIB size is larger than the BCH transport block size, the SIB will be split and transmitted in multiple transport blocks. If the SIB size is smaller than the BCH transport block size, several SIBs, the first split block, or the last split block are cascaded and placed in the same transport block. In order to correctly identify multiple SIBs or partitions included in a transport block, different types of SIBs or partitions will contain both the header field and the data domain. The partition block containing the header field and the data field is called Sub-block for system information.

When the system information block is transmitted on the broadcast channel, there are two forms of existence, one is the complete system information block (Complete SIB), and the other is the divided system information block.

After segmentation processing of a certain system information block, the divided block can be divided into a first split block (Fisirt segment), an intermediate split block (Subsequent segment), and a last split block (Last Segment), and the following three divided blocks are The data format is explained.

The Fkst segment includes: SIB type, SEG_COUNT, and SIB data; wherein, SIB type, SEG_COUNT is a header field; SIB type represents SIB data in the partition block. The corresponding SIB type; SEG_COUNT represents the total number of blocks divided by the SIB; SIB data represents the first piece of data after the SIB division.

The Subsequent segment includes: SIB type, Segment index, and SIB data; wherein, SIB type and Segment inde are header fields; SIB type has the same meaning as above, and Segment index represents the number of the partition, that is, the partition is the first partition Block, SIB data is stored in the Segment Index segment data after this SIB segmentation.

The Last segment includes: SIB type, Segment inde, and SIB data; The last segment content is basically the same as the Subsequent segment, and the SIB data stores the last segment of the data after the SIB segmentation.

The following describes Complete SIB, Complete SIB includes: SIB type and SIB data; where SIB type is header field, SIB type has the same meaning as above, SIB data has the same meaning, but only the entire SIB data is stored.

The existing BCH transmission protocol specifies that the SIB type occupied bits are 5 bits; the occupied bits of the SEG_CONT and the Segment index are 4 bits, and the information is called header information. Since these header information occupy part of the bits of the transport block, a transmission is caused. The effective data contained in the block is reduced, and the data transmission efficiency is low. In particular, when the system information block is divided into a plurality of transport blocks, part of the header information is included in each transport block, so that the problem of low data transmission efficiency is more obvious. Therefore, these header information can be regarded as redundant information of data in the transport block. The more the information, the longer the user's access delay and the worse the user experience.

In order to reduce the user's access delay and improve the user experience, this step needs to select a part of the system information block as the to-be-processed system information block from all the system information blocks in the system, and then perform the selected system information blocks. The processing makes the header information of the system information blocks actually reduce the number of bits, thereby improving the user experience.

Step 103: The base station sets a format of the system information sub-block, and includes: when the system information sub-block is the first divided block, setting a header field in the system information sub-block to include: a type mapping of the system information block The first type number and the total number of partitioned blocks of the system information block; when the system information sub-block is not the first divided block, setting the header field in the system information sub-block includes: type mapping of the system information block a first type number and a split block number; when the system information sub-block is a complete system information block, setting a header field in the system information sub-block includes: a first type number of a type mapping of the system information block; The number of bits occupied by the first type number is smaller than the ratio of the type of the system information block. Special number.

Mapping a system information block type (SIB type) of the to-be-processed system information block to a first type number, and including, in the scheduling information, a mapping relationship between the SIB type and the first type number, the first type The number of occupied bits of the model is less than 5 bits;

There are still 18 types of system information blocks in the WCDMA system (System Information

Block, SIB), respectively identified as SIB1 ~ SIB18, explain this step.

The standard type numbers of the 18 types of SIBs from SIB1 to SIB18 are 1 to 18, and each SIB type is identified by 5 bits. For example: "00000" identifies "1", "00001" identifies "2", "00010" The identifier "3", and so on; the SIB type is included in the header field of the system sub-information block. In order to reduce the bits occupied by the SIB type in the header information of certain types of SIBs, the SIB type of these SIBs needs to be performed. The mapping process is such that the first type number occupied by the mapping process is smaller than the SIB type occupied bit. That is, the first type number after the mapping process is less than 5 bits.

For example, when the SIBs of the four types of SIBs from SIB1 to SIB4 are respectively mapped to the SIBs of the SIBs to SIBs, the SIB types of the four types of SIBs are mapped to the first type numbers of the 2bits. The standard type number "00000" mapped to SIB1 is mapped to the first type number "00", the standard type number "00001" of SIB2 is mapped to the first type number "01", and the standard type number "00010" of SIB3 is mapped to The first type number is "10", and the standard type number "00011" of SIB4 is mapped to the first type number "11". After the mapping is completed, the SIB type of SIB1 to SIB4 and the first type number are The mapping is included in the scheduling information that needs to be sent to the user equipment, so that the user receives the system information block sent by the base station according to the scheduling information that includes the mapping relationship.

The scheduling information is explained below.

The MIB or SB transmitted in the broadcast channel includes scheduling information of each SIB, and the scheduling information mainly includes: a repetition period SIB_REP, a total number of segments SEG_COUNT, an initial position SIB_POS (position of the first segment), and a position offset SIB-OFF Information such as SIB_REP represents the repetition period of the system information block SIB, for example: If the repetition period is 4, it means that the SIB is sent once every 4 frames, and the frame is a 10 ms radio frame; each system information block, main system information block or The scheduling block should give its corresponding SIB_REP, which is usually defined as the smaller the SIB_REP, the higher its priority.

For a segmented SIB, since the position SIB_POS and offset SIB_OFF of the first segment are known, the position of the remaining segments can be determined by the formula SIB_POS(i) = SIB_POS(il) + SIB_OFF(i) Initiated, this is a recursive form, where i = 1, 2, · · · SEG_COUNT-l , SIB_OFF(i) means the offset of the i-th Subsequent segment relative to the i-1th. The SIB has a total of SEG_COUNT-1 SIB-OFF, and each SIB-OFF (i) value may be different.

Step 103: The base station sends scheduling information of the transport block and the system information sub-block on a broadcast channel, where the scheduling information includes a mapping relationship between a type of the system information block and a first type number. The system information block is periodically transmitted on the broadcast channel, and the system information block needs to be divided and/or cascaded according to the transport block size requirement of the broadcast channel to obtain multiple transport blocks, which may include one or more in each transport block. System information sub-blocks. The system information sub-block processed according to the above step 103 has the following forms:

When the system information sub-block is the first divided block, the header field includes a first type number corresponding to the system information sub-block and a total number of divided blocks of the system information;

Since the processed system information sub-block contains the first type number and does not include the SIB type, the number of bits occupied by the header information is reduced, and the redundant information is reduced. Since the UE only identifies the SIB according to the SIB type, it is also necessary to provide a mapping relationship between the SIB type and the first category number in the scheduling information, so that the UE identifies the corresponding SIB according to the mapping relationship.

The UE receives the system information block on the BCH, and receives the corresponding system information sub-block at the specified time according to the scheduling indication of the scheduling information for each system information sub-block, and reads each divided block in order and performs the parsing operation.

The foregoing embodiment of the present invention can be used to: include a first type number in a header field of some SIBs in the system, and the occupied bits of the first type number are smaller than the occupied bits of the SIB type, and the SIB of the systems is reduced in broadcasting. Redundant information in the channel improves the rate at which the broadcast channel transmits system information to improve the user experience. In the foregoing step 101 of the first embodiment of the present invention, at least one type of system information block is selected as the to-be-processed system information block according to a preset condition, and the embodiment of the present invention further provides various implementation manners, and the implementation manners are sequentially explained below. Description.

In a first implementation, the selecting at least one type of system information block as the to-be-processed system information block according to the preset condition may include:

For example: The preset first threshold is 10, and there are 18 types of SIBs in the system. Since the size of each type of SIB is different, the number of partitions is different. If there are 18 SIBs in the system, only SIB5 The number of partitions of SIB11 and SIB18 is greater than 10, and the number of divisions of the remaining SIBs is less than or equal to 10. The three SIBs of SIB5, SIB11 and SIB18 are selected as the system information blocks to be processed, and the system information is actually transmitted. The header field of the block contains the first type of block; and the remaining SIB1~SIB4, SIB6~SIB10, and SIB12~SIB17 are not processed in the fifteen types, and the existing transmission mode is still used. , still in the header field of the system information sub-block contains SIB type ₀

In a second implementation manner, the selecting at least one type of system information block as the to-be-processed system information block according to the preset condition may include:

Determining whether the version number of each type of system information block matches the preset version number;

For example: With the development of communication technology, 3G communication systems have been developed to the R12 version, and new system information types may be introduced in some versions. The preset version number may be one or more specified version numbers (continuous version numbers or discrete version numbers), or may be all version numbers after which version. For example, when the preset version number is R12, the system information block introduced by R12 is used as the system information block to be processed, and the SIBs introduced in other versions are still processed by the existing process.

In a third implementation manner, the selecting at least one type of system information block as the to-be-processed system information block according to the preset condition may include:

Determining whether the broadcast channel of the bearer system information block is a designated channel, and the designated channel is a main common control physical channel or an auxiliary common control physical channel; If yes, the system information block of this type is used as the to-be-processed system information block.

When the system simultaneously adopts two kinds of broadcast channels, a primary common control physical channel or a secondary common control physical channel, the third implementation manner can be used to perform the selection operation.

For example: When the system uses both the primary common control physical channel or the auxiliary common control physical channel, the designated channel is the auxiliary common control physical channel, and the SIB to be sent on the auxiliary common control physical channel is used as the system information to be processed. The block only processes the SIB transmitted on one of the broadcast channels, and the SIB transmitted on the other broadcast channel is still processed by the existing process.

In a fourth implementation manner, the selecting the at least one type of the system information block as the to-be-processed system information block according to the preset condition may include:

Determining whether the number of bits actually occupied by the type number of each type of system information block is smaller than the number of bits occupied by the SIB type;

For example, the SIB types of SIB1 to SIB4 are 1 to 4 in sequence. These SIBs can be represented by 2 bits, which is less than 5 bits of the SIB type; the SIB types of SIB5 to SIB8 are 5 to 8 in sequence, and the actual occupied bits of these SIBs are 3 bits are less than 5 bits of the SIB type; SIB types of SIB9 to SIB16 are 9 to 16 in sequence, and the actual occupied bits of these SIBs are 4 bits smaller than the bits occupied by the SIB type, so SIB1 to SIB16 can be selected as the 16 types of SIBs. System information block to be processed.

In a fifth implementation manner, the selecting at least one type of system information block as the to-be-processed system information block according to the preset condition may include:

For example: Judging the size relationship between the system information block size and the transport block size of the broadcast channel is to determine whether the system information block needs to be split. When the SIB size is larger than the transport block size of the broadcast channel, the SIB needs to be divided. When the SIB size is equal to the transport block size of the broadcast channel, and the SIB satisfies the transport block requirement of the broadcast channel, the SIB does not need to be split again. Sending on the broadcast channel; or, when the SIB size is smaller than the transport block size of the broadcast channel, the SIB needs to be cascaded with other types of SIBs or with other types of SIB partition blocks before being sent on the broadcast channel. In this implementation manner, system information blocks that do not need to be divided are used as system information blocks to be processed. In order to further reduce the redundancy information of the system information block in the broadcast channel, the embodiment of the present invention further provides a preferred solution, which is based on the method of the foregoing Embodiment 1, when the to-be-processed system information block is When dividing into at least two divided blocks, the header field of the system information sub-blocks of the system information blocks is further changed to reduce the redundancy therein. The preferred embodiment will be explained by taking Method Example 2 as an example.

Referring to FIG. 2, a flow chart of Embodiment 2 of a system information transmission method according to an embodiment of the present invention is shown, and the method may include:

Step 201: The base station selects at least one type of system information block as a to-be-processed system information block according to a preset condition.

Step 202: The base station performs segmentation and/or concatenation processing on the to-be-processed system information block according to a transmission requirement of a broadcast channel to obtain a transport block, where the transport block includes at least one type of system information sub-block. The system information sub-block includes: a header domain and a data domain;

Steps 201 to 202 are the same as steps 101 to 102 in the above embodiment, and are not described herein again.

Step 203: The base station sets a format of the system information sub-block, and includes: when the system information sub-block is the first divided block, setting the first type number corresponding to the system information sub-block in the header field, and a first block identifier, where the first block identifier has a number of bits less than 4 bits; when the system information sub-block is the last partition block, the first class corresponding to the system information sub-block is set in the header field a model number and a last block identifier, where the last block identifier has a number of bits less than 4 bits;

Alternatively, the header field of the system information sub-block is set to include a first type number and a check digit corresponding to the system information block, where the check digit has a bit number less than 4 bits.

In step 203, the header field of the first divided block includes the first block identifier, and does not include the divided total block, and the header field of the last divided block includes the last block identifier, and does not include the split block number. The first block identifier is different from the last block identifier, and the bits occupied by the first block identifier and the last block identifier are smaller than the bits occupied by the original number. If the to-be-processed system information block is divided into at least three partitioned blocks, in order to reduce the redundant information in the intermediate partitioning block, the method further includes: The base station sets the first type number and the intermediate block identifier corresponding to the system information sub-block in the header field of the system information sub-block, where the intermediate block identifier has a smaller number of bits than 4 bits.

Optionally, the identifier of the intermediate partition block may be the same as the first block identifier or the last block identifier.

Further, if the system information block to be processed needs to be divided, the header field of the system information sub-block obtained after the segmentation includes a first type number and a check digit corresponding to the system information block, where The check digit has a bit size less than 4 bits. For example: Set the check digit of the split block whose odd block number is odd to 1. Set the check digit of the split block whose even block number is even to 0. Then, the first type number and the first type block are included in the header field of the first split block, and the header field of the second split block includes the first type number and 0, and so on. Among them, the check field contains the check digit and can also be applied to the first split block and the last split block.

Further, if the system information block to be processed needs to be divided, the header field of the system information sub-block obtained as the intermediate block is divided into a first type number and a parity bit corresponding to the system information block, where The parity bit occupies less than 4 bits; the header field of the system information sub-block that is divided into the first partition includes the first type number and the first block identifier corresponding to the system information sub-block.

Optionally, the header field of the system information sub-block that is divided into the last partition block includes the first type number and the last block identifier corresponding to the system information sub-block.

For example: Set the first block identifier "00" to identify the first split block, the last block identifier "11" to identify the last split block, set "01" to identify the even block of the intermediate split block, and set "10" to identify the odd number of the intermediate split block. The first block identifier, the last block identifier, and the intermediate partition block identifier occupy bits are all 2 bits, and both are less than 4 bits. For another example, the first block identifier "0" is set to identify the first partition block, and the middle partition block identifier "0" is set to identify the intermediate partition block, that is, the intermediate partition block has the same representation as the first block identifier, "1" identifier. The last split block. Then, the first block identifier, the identifier of the intermediate partition block, and the last block identifier occupying bits are all 1 bits, which are all less than 4 bits.

Step 204: The base station sends scheduling information of the transport block and the system information block on a broadcast channel, where the scheduling information includes a mapping relationship between a type of the system information block and a first type number.

It can be seen from the foregoing embodiment of the present invention that: based on mapping the SIB types of some SIBs in the system to the first type number, the partition block format of the SIBs that are divided and processed in the SIBs is also The settings are made to reduce the amount of redundant information in the segmentation block, which improves the user experience. In order to further reduce the redundant information of the broadcast channel transmission system information, the embodiment of the present invention further provides another system information transmission method, which is explained below in conjunction with FIG. 3.

Referring to FIG. 3, a flowchart of Embodiment 3 of a system information transmission method according to an embodiment of the present invention is shown, and the method may include:

Step 301: The base station performs segmentation and/or concatenation processing on the system information block according to the transmission requirement of the broadcast channel to obtain a transport block, where the transport block includes a system information sub-block composed of a data domain. In an actual application, the system The size of the information block may be different from the transport block size of the broadcast channel. In order to ensure that the system information block is normally transmitted on the broadcast channel, and the length of the system information block must match the size of the P-CCPCH transport block, the system information block needs to be performed. Segmentation and/or cascading. For example: The transmission requirements of the broadcast channel P-CCPCH are: fixed transmission interval 20ms, fixed transmission block 246bits, when the system information block needs to be broadcast on the P-CCPCH, the length of the system information block must be the same as the P-CCPCH transmission block. The sizes match, therefore, the system information block must be segmented and/or cascaded according to the transmission requirements of the P-CCPCH. The processed system information sub-blocks included in the transport block are processed, if cascaded. Operation, a transport block may contain more than one system information sub-block.

The existing system information sub-blocks have the following four formats: complete contains: SIB type and data; First segment contains: SIB type, SEG-COUNT and SIB data; Subsequent segment contains: SIB type, Segment inde and SIB data; Last The segment contains: SIB type, Segment index, and SIB data, where SIB type, SEG_COUNT, and Segment index are included in the header field and are referred to as header information.

In this step, the system information sub-block contains only SIB data and does not contain a header field.

Step 302: The base station sends scheduling information of a system information block on a broadcast channel, where the scheduling information includes indication information of a system information sub-block included in a transport block of the broadcast channel.

Step 302: The base station sends the transport block on a broadcast channel.

After the processing of the system information sub-block in the transport block in step 301, the header field is no longer included in the system information sub-block, and the amount of data transmitted is maximized, and each system information element is also indicated in the scheduling information sent to the UE. The transmission moment of the block, so that the UE knows which one to receive at which time. Which system information sub-block of the system information block.

It can be seen from the above embodiment that when the system information block is transmitted on the broadcast channel, by reducing the size of the header field, the transport block carries the valid data to maximize the redundant information of the system information block during transmission, thereby enabling Improve the user experience. On the basis of the foregoing embodiment 3, further, the embodiment of the present invention further provides a preferred solution, which performs masking processing on the foregoing transport block that does not include a header field, so that the UE performs calibration when receiving the transport block. The processing is performed to ensure that the UE receives the reliability of the system information sub-block.

Optionally, before the sending, by the base station, the transport block on a broadcast channel, the method further includes:

The base station performs masking processing on the transport block by using indication information of the transport block.

For example: when the system information sub-block in the transport block is complete, the transport block is masked by the SIB type (or SIB type and the number of split blocks) of the system information sub-block; when the system information in the transport block is When the sub-block is a Fkst segment, the transport block is masked by using the indication information SIB type and SEG_COUNT of the system information sub-block; when the system information sub-block in the transport block is a Subsequent segment, the indication of the system information sub-block is utilized. The information SIB type and the Segment index perform a masking process on the transport block. When the system information sub-block in the transport block is a Last segment, the transport block is masked by using the indication information SIB type and the Segment index of the system information sub-block.

If a transport block includes at least two types of system information sub-blocks, optionally, the transport block is masked by using the indication information of the system information sub-block, including:

The indication information of any type of system information sub-block is selected, and the transport block is masked. For example: You can select the SIB type of any system information sub-block to mask the transport block, or select the type of system information sub-block and the total number of split blocks to mask the transport block, or select system information. The transport block is masked by the type of block and the split block number.

Preferably, if a transport block includes at least two types of system information sub-blocks, the transport block may be masked by selecting an indication of the SIB with the smallest SIB type number.

Optionally, the masking of the transport block by the indication information means that the data packet transmitted in the air interface is masked by the indication information; or the indication information is The data packets transmitted by the port are masked at the medium access control layer.

The terminal sequentially receives each transport block according to the transmission moment of the system information sub-block in the transport block indicated in the scheduling information, and demasks the received transport block according to the indication information to determine whether the received transport block is correct. If the de-masking is successful, it indicates that the received transport block is correct; otherwise, it indicates that the received transport block is incorrect. At this time, the terminal can directly discard the transport block. In this way, the terminal is prevented from being judged until all the transport blocks are received, the reliability of the terminal receiving the transport block is improved, and the user experience is improved indirectly.

Optionally, in the foregoing embodiment of the present invention, the network side may perform the foregoing operations on a part of the system information block, and the partial system information block may perform the selection of the system information block according to the manner in Embodiment 1.

According to the embodiment of the present invention, when the system information block is transmitted on the broadcast channel, the header field is reduced, so that the transport block carries the valid data to maximize the redundant information of the system information block during transmission. The user experience can be improved; and the transmission block is further masked by using the indication information of the system information sub-block included in the transport block, thereby improving the reliability of the terminal receiving the transport block. In order to further reduce the redundant information of the broadcast channel transmission system information, the embodiment of the present invention further provides another system information transmission method, which is explained below in conjunction with FIG.

Referring to FIG. 4, a flowchart of Embodiment 4 of a system information transmission method according to an embodiment of the present invention is shown, and the method may include:

Step 401: The base station performs segmentation and/or concatenation processing on the system information block according to the transmission requirement of the broadcast channel to obtain a transport block, where the transport block includes at least one type of system information sub-block, and the system information sub-block includes: Header and data fields.

Step 402: The base station sets a format of the system information sub-block, including: when the system information sub-block is the first divided block, setting a type corresponding to the system information sub-block and a first block identifier in the header field The first block identifier has a bit number less than 4 bits; when the system information sub-block is the last segment, the header field includes a type corresponding to the system information sub-block and a last block identifier, Wherein the last block identifier has a number of bits less than 4 bits;

Or setting a header corresponding to the system information block in a header field of the system information sub-block a type number and a check digit, where the check digit occupies less than 4 bits;

When the system information block size is larger than the transport block size of the broadcast channel, the system information block needs to be divided into at least two divided blocks. For example: When the system information block needs to be transmitted in three transport blocks after being divided, the corresponding system information sub-block has three types of formats, Fkst segments Subsequent segment and Last segment _0, where the First segment refers to the system information block. The first segmentation block, Last segment, refers to the last segmentation block of the system information block.

When the system information sub-block is a first segment, the header field includes a SIB type and a first block identifier corresponding to the system information sub-block;

When the system information sub-block is a Last segment, the header field includes a SIB type and a last block identifier corresponding to the system information sub-block.

The first block identifier and the module identifier are less than 4 bits.

The First segment processed in this step includes: SIB type, first indicator and data; Last segment includes: SIB type, last indicator and data; due to the first block identifier and the last block identifier occupying bits Less than 4bits, therefore, a certain channel capacity can be saved.

Step 403: The base station sends scheduling information of the transport block and the system information block on a broadcast channel.

Optionally, the scheduling information may further include an indication that the system information block adopts a first block identifier and a last block identifier.

Optionally, if the to-be-processed system information block is divided into at least three divided blocks, the method further includes:

If the system information sub-block is a Subsequent segment, the header field includes an SIB type and an intermediate block identifier corresponding to the system information sub-block.

Optionally, the intermediate block identifier may be the same as the first block identifier or the last block identifier.

Further, the header field of the system information sub-block includes a parity bit, and the parity bit occupies less than 4 bits.

For example, the header field of the system information sub-block includes a parity bit, and the number of the system information sub-block received by the receiving end check is odd or even. If "representative is a segmentation block numbered odd, "0" represents a segmentation block whose number is an even number. Then the header field of the fkst segment The SIB type and the odd block indication bit (set to 1) are included, and the header field of the system information sub-block including the second divided block includes the SIB type and the even block indication bit (set to 0), and so on.

It can be seen from the above embodiments of the present invention that reducing the header field of the system information sub-block obtained by dividing the system information block can reduce the redundant information of the system information block during transmission, thereby improving the user experience.

When the system information sub-block is the first split block, the header The domain includes a first type number corresponding to the system information sub-block and a total number of partitioned blocks of the system information block; when the system information sub-block is not the first divided block, the header field includes system information a first type number corresponding to the sub-block and a number of the partition block; when the system information sub-block is a complete system information block, the header field includes a first type number corresponding to the system information sub-block;

Step 503: The terminal parses the system information block according to the scheduling information and the information included in the received system information sub-block header field.

It can be seen from the foregoing embodiment that: the first type number is included in some SIB header fields in the system, and the occupied bits of the first type number occupying bits are smaller than the SIB type, which reduces the SIB of the systems in the broadcast channel.
