Description

Method for transmitting information and base station and terminal

Technical field

The embodiments of the present invention relate to the field of communications, and in particular, to a method for transmitting information, a base station, and a terminal.

Background technique

In the existing communication system, the user equipment first receives the control channel, determines the transport block size (TBS, Transport Block Size) carried by the data channel scheduled by the control channel according to the control information in the received control channel, and determines the transport block. Data can be detected after it has been sized. For example, in a Long Term Evolution (LTE) system, the control channel may be a Physical Downlink Control Channel (PDCCH) or an Enhanced Physical Downlink Control Channel (EPDCCH), and the data channel may be The physical downlink shared data channel (PDSCH) is a physical downlink shared channel (PDSCH), and the user equipment determines the TBS of the transport block carried by the PDSCH according to the control information carried in the PDCCH or the EPDCCH. Since the control channel indicates the TBS of the transport block carried by the data channel before the data channel is received, the TBS of the transport block carried by the data channel can be flexibly changed as needed.

In the information processing process in the communication system, the user equipment first receives the control channel of the scheduling information before receiving the information, and determines the transport block size of the carried information according to the received control channel. The information is then received in accordance with the determined transport block size. In an overlay-enhanced scenario, the information needs to be repeated many times for reliable transmission. If the transmission of the information is also based on the scheduling of the control channel, the user equipment needs to successfully detect the control channel first, and then detect the information according to the transport block size determined by the control channel. In this way, for the user equipment to successfully receive information, the control channel needs to be repeated many times, and the information needs to be repeated many times, thereby increasing the resource overhead of the system, reducing the resource utilization of the network, and greatly increasing the detection complexity and work of the user equipment.

First, the system architecture of the method for transmitting information of the present invention is introduced. The present invention is mainly applied to an LTE system or an advanced LTE-Advanced (LTE-Advanced) system. The present invention can also be applied to other communication systems, for example, Wideband Code Division Multiple Access (WCDMA), Time Division-Synchronous Code Division Multiple Access (TD-SCDMA), and the like. As long as there is an entity in the communication system that can send information, other entities in the communication system can receive the information. For example, the information is one or more of system information, a random access response (RAR) message, and a paging message.

Please refer to FIG. 1 , which is a system frame used in the communication system for transmitting the information of the present invention. As shown in FIG. 1 , a base station (English name Base station) and user equipments (UE, User Equipment) 1 to UE 6 form a communication system in which the base station transmits system information, RAR messages, and paging messages. One or more of the UE1 to UE6, the base station is the sender device in the method for transmitting information of the present invention, and UE1 to UE6 are the receiver devices in the method for transmitting information of the present invention. In addition, UE4 to UE6 also form a communication system, in which UE5 can be implemented as a function of a base station, and UE5 can send one or more of system information, RAR message and paging message to UE4 and UE6. One or more UEs.

The details are described below separately.

An embodiment of the method for transmitting information of the present invention is applicable to the sending of information by a base station. Referring to FIG. 2, the method for transmitting the information may include the following steps:

201. Divide a transport block for carrying information into at least two transport sub-blocks, where each transport sub-block includes a part of the transport block.

In the embodiment of the present invention, the base station sends information to the terminal, and the information is carried in the transport block. The information may specifically be one or more of control information, data, and messages. For example, the information is: system information, system information block, control information of scheduling system information, control information of scheduling system information block, random access response, control information for scheduling random access response, paging message, control of scheduling paging message One or more of information, group message, control information of the scheduling group message, main information block, proprietary data, control information for scheduling proprietary data, public message, and control information for scheduling the public message. Also in the present invention, the transport block reflects the composition or composition of the information. In particular, the transport block can be a data block, a packet, or a message block. A group message means that the message contains information about a group of UEs. A public message refers to a message that all UEs in a cell can receive.

In the embodiment of the present invention, after the base station divides a transport block into multiple transport sub-blocks, in order to enable the peer device to receive the transport sub-blocks, the indication information needs to be generated, and the transmission sequence of the transport sub-blocks needs to be prior. The transmitted transmission sub-block carries indication information indicating the transmission sub-block to be transmitted later, so that the peer device can receive the transmission sub-block transmitted later according to the indication information. Specifically, the indication information may include: size information of the indicated transmission sub-block, and/or indication information indicating the transmission block. That is to say, the indication information may only indicate the size of the transmission sub-block, the indication information may also be indication information indicating the transmission block, or the indication information may simultaneously indicate the above situation. For example, the indication information carried by the transmission sub-block transmitted first may indicate the size of the transmission sub-block transmitted thereafter, and the indication information carried by the transmission sub-block transmitted first may also be an indication indicating the entire transmission block. information.

In some embodiments of the present invention, the indication information includes one or more of the following: size information of a transmission sub-block or a transport block, modulation information of a transmission sub-block or a transport block, a coding sub-block or a coding of a transport block. Information, time resource information of the transmission sub-block, frequency resource information of the transmission sub-block, and number information of the transmission sub-block.

For another example, the indication information is: size indication information, modulation information, coding information, repetition information, time resource information, frequency resource information, coverage enhancement level information, power setting information, number of transmission sub-blocks, and transmission block is divided into transmission sub- One or more of the number of pieces of information, the number of pieces of transmission sub-blocks that the UE needs to receive, the network capability information, the base station capability information, the coverage size, the number of repetitions, the repetition level, the narrowband resource information, and the frequency hopping indication information.

In a particular implementation level of the indication information, in some embodiments of the invention, the indication information is included in the transport block. Alternatively, the indication information is not included in the transport block, and the indication information is carried in the transport sub-block after being generated. That is to say, the indication information may be originally included in the transport block, and such indication information usually exists at the upper layer of the protocol stack. In the present invention, such indication information may be carried in the transmission sub-block transmitted first to implement an indication of the transmission sub-block transmitted later. In other embodiments of the present invention, the indication information used may not be in the transport block but generated in the physical layer, and the generated indication information is carried in the previously transmitted transport sub-block to implement the transport sub-block for the post-transmission. Instructions.

In the embodiment of the present invention, after the base station determines the transport block for carrying information, the transport block needs to be divided into at least two transport sub-blocks, and all the contents of the transport block are dispersed into multiple transport sub-blocks, and each transmission is performed. Each of the sub-blocks carries a part of the content of the transport block, and the base station may divide the transport block according to the block-by-block manner. Specifically, in step 201, before the transport block for carrying system information is divided into at least two transport sub-blocks, the information of the present invention The transmission method may further include the following steps:

A1, by means of a predetermined method for determining that the transport block is divided into transport sub-blocks; or

A2. Determine the blocking mode of the transmission block into transmission sub-blocks, and notify the peer device of the blocking mode by explicit or implicit methods.

In the step A1, the base station firstly obtains the block mode by using the block mode, and the block mode indicates that the transport block is divided into the transmission sub-blocks, and the predetermined block mode can be mutually known between the base station and the terminal, for example, It can be in the manner of equalizing the size of the transport block, or the method of fixing the number of blocks, or the method of fixing the size of a certain sub-block. The use of pre-defined can facilitate the use of base stations and terminals.

In step A2, the base station may set the blocking mode by itself, and notify the user after determining the blocking mode by itself. The peer device (such as the terminal), the self-determined blocking mode can satisfy the autonomous needs of the base station, and can determine the blocking mode of the transport block in combination with the transmission resource status of the base station itself. For example, the base station may determine the size of each transmission sub-block in combination with the bandwidth, or determine the size of each transmission sub-block in combination with the current idle state of the base station. The transport block is divided into a plurality of transport sub-blocks, and the system or the standard may pre-determine the partitioning manner in which the transport block is divided into multiple transport sub-blocks, or the base station (or system) adopts explicit or implicit manner. The method indicates to the terminal a blocking manner in which the transport block is divided into a plurality of transport sub-blocks. For example, the base station sends block signaling to the terminal, indicating the block mode of the transport block, or uses a new field in the existing information to indicate the block mode of the transport block.

In some embodiments of the present invention, before the step 201 divides the transport block for carrying system information into at least two transport sub-blocks, the method for transmitting information of the present invention may further include the following steps:

B1. Determine, according to a preset, size information of one of the at least two transmission sub-blocks; or

B2: Determine the size of one of the at least two transmission sub-blocks, and indicate the size information of one of the at least two transmission sub-blocks to the peer device by using signaling or sequence.

In step B1, the size information of a transmission sub-block is determined according to a preset, and the pre-defined may be a system specification, or may be an upper-layer device specification of the base station, such as a Mobile Management Entity (MME). The transmission sub-block determined by the base station according to the predetermined specification may specifically be the transmission sub-block of the first transmission, that is, the size information of the transmission sub-block transmitted by the first one of the at least two transmission sub-blocks is determined according to a predetermined specification. Another method for determining the size of the transmission sub-block is given in step B2. The base station determines the size of a transmission sub-block by itself, and notifies the peer device (ie, the terminal) after determining the size of one transmission sub-block. The method of determining the size of a transmission sub-block by itself can satisfy the autonomous needs of the base station, and can determine the size of a certain transmission sub-block in combination with the transmission resource status of the base station itself. The base station may specifically be the transmission sub-block of the first transmission according to the self-determined transmission sub-block, that is, the base station determines the size of the transmission sub-block transmitted by the first one of the at least two transmission sub-blocks, and indicates by signaling or sequence. Give the peer device the peer device to know the size of the first transmitted transport sub-block.

In some embodiments of the present invention, step 201 divides a transport block for carrying system information into at least two transport sub-blocks, and specifically includes the following steps:

The transport block is divided into the same number of transport sub-blocks according to the number of code blocks included in the transport block, wherein one transport sub-block includes one code block, or one transport sub-block includes one code block and indication information.

Wherein, if a code block is included in the transport block, the transport block may be divided into units of code blocks, that is, Corresponding to one code block in a transport block, the transport block includes several code blocks and can be divided into several transport sub-blocks, and the transport sub-block corresponds to the code block included in the transport block, one transmission A sub-block may include one code block, or one transmission sub-block includes a code block and indication information. That is, the transmission sub-block may be only one code block, or may be composed of one code block and indication information indicating the code block transmitted later. The transmission sub-block is determined according to the composition of the code block in the transport block, and a plurality of transmission sub-blocks can be obtained with a small modification of the original transport block, and the modification to the original transport block is minimized.

202. Perform each of the at least two transmission sub-blocks that are divided into independent transmissions, and the transmission sub-blocks that are first transmitted in the at least two transmission sub-blocks include indication information indicating the transmission sub-blocks that are transmitted later. .

In the embodiment of the present invention, after the base station divides one transport block into at least two transport sub-blocks, it performs independent transmission for each transport sub-block, that is, each of the at least two transport sub-blocks is separate. The separate transmission of each transmission sub-block sent to the peer device (ie, the terminal) enables the peer device to receive each transmission sub-block one by one. The specific content of the indication information carried by different transmission sub-blocks may be different. Different transmission sub-blocks can be transmitted independently. Independent mapping is performed if different transmission sub-blocks perform independent coding and/or rate matching.

In some embodiments of the present invention, if the transport block is divided into the first transport sub-block, the second transport sub-block, and the third transport sub-block in step 201, that is, divided into a minimum of three transport sub-blocks, step 202 is divided into Each of the at least two transmission sub-blocks is independently transmitted, and specifically includes the following steps:

Or the first transmission sub-block includes indication information indicating the second transmission sub-block, the second transmission sub-block includes indication information indicating the third transmission sub-block, and the third transmission sub-block does not include the indication information;

Or the first transmission sub-block includes indication information indicating the second transmission sub-block and indication information indicating the third transmission sub-block, and the second transmission sub-block and the third transmission sub-block do not include the indication information.

Specifically, when the first transmission sub-block, the second transmission sub-block, and the third transmission sub-block are independently transmitted, the first transmission sub-block is transmitted first, then the second transmission sub-block is transmitted, and then the third transmission sub-block is transmitted. The size of the first transmission sub-block may be predetermined or indicated to the terminal by the base station itself. Carrying in the first transmission sub-block Indicates the indication of the transmitted sub-transport sub-block. The second transmission sub-block and the third transmission sub-block may both carry indication information or do not carry indication information. In an implementation manner described above, the first transmission sub-block, the second transmission sub-block, and the third transmission sub-block all carry indication information. In another case, the first transmission sub-block and the second transmission sub-block carry indication information, and the third transmission sub-block does not carry indication information. In another case, only the first transmission sub-block carries the indication information, and the second transmission sub-block and the third transmission sub-block do not carry the indication information.

The description of the present invention by the above embodiment shows that the transport block for carrying information is first divided into at least two transport sub-blocks, wherein each transport sub-block contains part of the content in the transport block, and will be divided into at least two. Each of the transmission sub-blocks is independently transmitted, and the transmission sub-blocks transmitted in the at least two transmission sub-blocks include indication information indicating the transmission sub-blocks transmitted later. The transport block carries information, and the transport block is divided into a plurality of transport sub-blocks, each of which is independently transmitted, and the transport sub-block transmitted first can indicate the transport sub-block transmitted later, thereby After the transmission of the entire information is completed, the terminal may receive the transmitted sub-block transmitted according to the indication information in the transmission sub-block received first, and then obtain a complete transport block, and all the information carried by the transport block can be obtained. Since the control information is not required to be used to schedule the information transmission block, information transmission and reception can be realized, and the control channel is avoided, so that only less network resources are needed, and the detection power consumption of the user equipment can be omitted.

In the foregoing embodiment, the method for transmitting information is described from the base station side, and then the method for transmitting information provided by the present invention is described from the peer device (terminal) side of the base station. Referring to FIG. 3, another embodiment of the present invention is shown. The method for transmitting the provided information may include the following steps:

301. Determine at least two transport sub-blocks constituting a transport block, wherein each transport sub-block includes a part of the content in the transport block.

In the embodiment of the present invention, the information is carried in the transport block, and the terminal needs to obtain the complete transport block in order to obtain the information carried in the transport block. The base station divides the transport block into multiple transport sub-blocks and performs independent transmission. The terminal also needs to first determine that one transport block is divided into multiple transport sub-blocks, and the terminal also determines that each transport sub-block contains a part of the transport block. Content, the content contained in each transmission sub-block is combined to obtain the content of the transport block.

In the embodiment of the present invention, the terminal may determine, according to the block mode, how the base station divides the transport block. Specifically, before the step 301 determines the at least two transport sub-blocks constituting the transport block, the method for transmitting information of the present invention may further include the following steps:

C1, by pre-determining a method of determining that the transport block is divided into transport sub-blocks; or

C2: Determine, according to an explicit or implicit notification method of the peer device, a partitioning manner in which the transport block is divided into transport sub-blocks.

In the step C1, the terminal firstly obtains the block mode by using the block mode, and the block mode indicates that the transport block is divided into the transport sub-blocks. The pre-defined block mode can be known between the base station and the terminal. For example, it may be a method in which the size of the transport block is equally divided, or a method of fixing the number of blocks, or a method of fixing a certain sub-block size. The use of pre-defined can facilitate the use of base stations and terminals.

In step C2, the base station can set the blocking mode by itself, and notify the peer device (ie, the terminal) after determining the blocking mode by itself. The self-determined blocking mode can satisfy the autonomous needs of the base station, and can be combined with the transmission of the base station itself. The resource status determines the way the block is transferred. For example, the base station sends block signaling to the terminal, indicating a fast blocking mode, or uses a new field in the existing information to indicate the blocking mode of the transport block. The terminal receives the indication of the base station, and determines, according to the explicit or implicit notification method of the base station, the block mode in which the transport block is divided into the transport sub-block.

In some embodiments of the present invention, step 301 determines at least two transport sub-blocks constituting a transport block, and specifically includes the following steps:

The number of transmission sub-blocks included in the transport block is determined according to the number of code blocks included in the transport block, wherein one transport sub-block includes one code block, or one transport sub-block includes one code block and indication information.

If the base station side divides the transmission sub-block according to the code block, the terminal side may determine the number of transmission sub-blocks according to the number of code blocks when determining the transmission sub-block, and the transmission block includes several code blocks, and the transmission block may be divided into For several transmission sub-blocks, the transmission sub-block corresponds to a code block included in the transport block, one transport sub-block may include one code block, or one transport sub-block includes one code block and indication information, that is, the transport sub-block may only It is a code block, and may also be composed of one code block and indication information carrying a code block transmitted later. The transmission sub-block is determined according to the composition of the code block in the transport block, and a plurality of transmission sub-blocks can be obtained with a small modification of the original transport block, and the modification to the original transport block is minimized.

302. Independently receive at least two transmission sub-blocks sequentially transmitted in the transport block, where the first transmission sub-block transmitted in the at least two transmission sub-blocks includes indication information indicating the transmission sub-block to be transmitted later.

In the embodiment of the present invention, after the terminal first determines that one transport block is divided into multiple transport sub-blocks, the terminal sequentially receives each transport sub-block independently according to the sending sequence of the base station, because the transport sub-block transmitted first includes the backward The transmitted transmission sub-block performs the indicated indication information, and the terminal acquires the first transmission After the transmission of the sub-block, the indication of the transmission sub-block transmitted after the transmission is obtained from the indication information carried in the transmission sub-block that is transmitted, and the transmission sub-block transmitted after the base station is received according to the indication information.

In the embodiment of the present invention, the base station combines the transmission sequence of the transmission sub-blocks, and needs to carry the indication information indicating the transmission sub-blocks transmitted later in the transmission sub-blocks that are transmitted first, so that the terminal can transmit the information according to the indication information. The transmission sub-block is received. Specifically, the indication information may include: size information of the indicated transmission sub-block, and/or indication information indicating the transmission block. That is, the indication information may only indicate the size of the transmission sub-block, and the indication information may also be indication information indicating the transmission block, or the indication information may simultaneously indicate the foregoing situation, for example, the indication information carried by the transmission sub-block transmitted first may be Indicates the size of the transmission sub-block transmitted thereafter, and the indication information carried by the transmission sub-block transmitted first may also be indication information indicating the entire transmission block.

For example, the indication information is: size indication information, modulation information, coding information, repetition information, time resource information, frequency resource information, coverage enhancement level information, power setting information, number of transmission sub-blocks, and transport block divided into transmission sub-blocks. One or more of the number information, the number of transmission sub-blocks that the UE needs to receive, the network capability information, the base station capability information, the coverage size, the number of repetitions, the repetition level, the narrowband resource information, and the frequency hopping indication information.

In some implementations of the indication information, in some embodiments of the present invention, the indication information is included in the transport block; or the indication information is not included in the transport block, and the indication information is carried in the transport sub-block after being generated. That is to say, the indication information may be originally included in the transport block, and such indication information usually exists at the upper layer of the protocol stack. In other embodiments of the present invention, the indication information used may not be in the transport block but generated in the physical layer, and the generated indication information is carried in the previously transmitted transport sub-block to implement the transport sub-block for the post-transmission. Instructions.

In some embodiments of the present invention, before the step 302 receives the at least two transport sub-blocks that are sequentially transmitted in the transport block, the method for transmitting information provided by the present invention may further include the following steps:

D1, determining, according to a preset, size information of one of the at least two transmission sub-blocks; or

D2. Receive signaling, and determine one of the at least two transmission sub-blocks according to the received signaling. Block size information; or,

D3. The receiving sequence determines, according to the received sequence, size information of one of the at least two transmission sub-blocks.

The terminal may first determine the size of a certain transmission sub-block, and the size of other transmission sub-blocks may also be determined according to the determination manner of one transmission sub-block. In step D1, the size information of one transmission sub-block is determined according to a preset, and the pre-defined may be a system specification, or may be an upper-layer device specification of the base station, such as an MME. The transmission sub-block determined by the terminal according to the predetermined specification may specifically be the transmission sub-block of the first transmission, that is, the size information of the transmission sub-block transmitted by the first one of the at least two transmission sub-blocks is determined according to a predetermined specification. In step D2, another way of determining the size of the transmission sub-block is given. The base station determines the size of a transmission sub-block by itself, and notifies the peer device (ie, the terminal) after determining the size of one transmission sub-block. The transmitted signaling determines a transmission sub-block size. This method can meet the autonomous needs of the base station, and can determine the size of a certain transmission sub-block in combination with the transmission resource status of the base station itself. The transmission sub-block determined by the terminal according to the received signaling may specifically be the transmission sub-block of the first transmission, that is, the terminal determines, according to the received signaling, the transmission sub-block of the first transmission of the at least two transmission sub-blocks. size. Another way of determining the size of the transmission sub-block is given in step D3, and the terminal determines a transmission sub-block size according to a sequence transmitted in advance. The transmission sub-block determined by the terminal according to the received sequence may specifically be the transmission sub-block of the first transmission, that is, the terminal determines, according to the received signaling, the size of the transmission sub-block transmitted by the first one of the at least two transmission sub-blocks. .

In some embodiments of the present invention, step 302 independently receives at least two transport sub-blocks that are sequentially transmitted in the transport block, and specifically includes the following steps:

E1: Obtain indication information indicating that the transmitted transmission sub-block is transmitted according to the received transmission sub-block that is transmitted first;

E2: Continue to receive the transmitted transmission sub-block according to the indication information included in the transmission sub-block that is transmitted first.

The terminal independently receives the plurality of transmission sub-blocks that are sequentially transmitted, and specifically, the steps E1 and E2 are used, and the terminal obtains the indication information carried by the terminal from the transmission sub-block received first, and obtains the transmission sub-block transmitted by the indication information. The indication can thus continue to receive the transmitted sub-block after transmission. The terminal relies on the indication information indicating the transmission sub-block carried by the transmission sub-block that is transmitted first to transmit the transmitted transmission sub-block without receiving the control channel, and saves the resource for the terminal. Reduce the power consumption of the terminal.

303. Determine a transport block according to receiving at least two transport sub-blocks in sequence.

In the embodiment of the present invention, after the terminal sequentially receives the plurality of sub-transport blocks, the terminal combines the at least two transmission sub-blocks received in sequence, so that a transport block can be obtained, and the complete block is parsed from the transport block. information.

In the embodiment of the present invention, after the base station divides one transport block into at least two transport sub-blocks, it performs independent transmission for each transport sub-block, that is, each of the at least two transport sub-blocks is separate. The separate transmission of each transmission sub-block sent to the peer device (ie, the terminal) enables the peer device to receive each transmission sub-block one by one. The specific content of the indication information carried by different transmission sub-blocks may be different. Different transmission sub-blocks can be transmitted independently. Independent mapping is performed if different transmission sub-blocks perform independent coding and/or rate matching. The terminal is independently self-decodeable for each transmission sub-block, and the terminal can combine the information contained in the received multiple transmission sub-blocks to obtain the information carried by the transmission block.

The foregoing description of the present invention shows that at least two transport sub-blocks constituting a transport block are first determined, wherein each transport sub-block includes a part of the content in the transport block, and then at least two of the transport blocks are sequentially received. a transmission sub-block, wherein the transmission sub-block first transmitted in the at least two transmission sub-blocks includes indication information indicating the transmission sub-block transmitted later, and finally determines the transmission block according to the at least two transmission sub-blocks received in sequence . The transport block carries information, and the transport block is divided into a plurality of transport sub-blocks, each of which is independently transmitted, and the transport sub-block transmitted first can indicate the transport sub-block transmitted later, thereby After the transmission of the entire information is completed, the terminal may receive the transmitted sub-block transmitted according to the indication information in the transmission sub-block received first, and then obtain a complete transport block, and all the information carried by the transport block can be obtained. Since the control information is not needed to schedule the transport block, the information can be sent and received. Therefore, only less network resources are needed, the control channel is avoided, and the power consumption of the user equipment can be omitted.

To facilitate a better understanding and implementation of the foregoing solutions of the embodiments of the present invention, the following application scenarios are specifically illustrated.

FIG. 4 is a schematic structural diagram of a transport block according to an embodiment of the present invention. The transport block is divided into three transport sub-blocks, and the three transport sub-blocks are respectively: Subblock 1, transport subblock 2, transport subblock 3. Each transport sub-block may be transmitted on one or more subframes, and the multiple subframes may be consecutive subframes or non-contiguous subframes.

Wherein, if the transmission order of the three transmission sub-blocks is: transmission sub-block 1, transmission sub-block 2, transmission sub- Block 3, the size of the first transmission sub-block is preset, or pre-configured, or signaling indication, or sequence indicated. It can be indicated by the main information block or by a reference signal. The previously transmitted transport sub-block contains indication information for the transport sub-blocks transmitted later, and/or the currently transmitted transport sub-block may also contain indication information for the transport block.

The indication information may be included in the transport block, and when the transport block is divided into a plurality of transport sub-blocks, the transport sub-block carries indication information of the transport block. Alternatively, the indication information is not included in the transport block, and the transport sub-block is formed according to the split transport block and the indication information, and the indication information is carried by the transport sub-block. The information (or bit) position of the indication information in the transmission sub-block is fixed, or preset, or signaled.

One transport sub-block may contain indication information for another transport sub-block, or one transport sub-block may contain indication information for multiple transport sub-blocks. A transport sub-block may also not include indication information. The first transport sub-block may be referred to as a primary transport sub-block, and the non-first transport sub-block may be referred to as a secondary transport sub-block. The primary transport sub-block may contain indication information for one or more secondary transport sub-blocks.

For example, the previous transport sub-block indicates an association between the transport sub-block size of the subsequent transport sub-block and the size of the particular transport sub-block. Specifically, as the previous transmission sub-block indicates that the transmission sub-block size of the subsequent transmission sub-block is X times the size of the specific transmission sub-block. Wherein, the specific transmission sub-block may be the first transmission sub-block. X can be a positive integer, or a fraction, or 0. For example, if the information carried by the current transmission sub-block indicates X=0 or X<=Y, it means that no sub-block is transmitted after the current transmission sub-block. Or, the current transmission sub-block is the last transmission sub-block. Where Y is a specific value. For example, Y=1. Typically, X is a value of 4, 2, 1, 0, 1/2.

For example, the previous transport sub-block indicates the transport sub-block size of the subsequent transport sub-block. After receiving the previous transmission sub-block, the UE learns the transmission sub-block size of the subsequent transmission sub-block, and then receives the subsequent transmission sub-block according to the obtained transmission sub-block size of the subsequent transmission sub-block.

Wherein, one transport block is divided into a plurality of transport sub-blocks in such a manner that the number of transport sub-blocks into which the transport block is divided is not fixed. Another type of transport block is divided into a plurality of transport sub-blocks in such a way that the number of transport sub-blocks into which the transport block is divided is fixed or limited. For example, a transport block is divided into 2 transport sub-blocks or up to 2 transport sub-blocks. For example, a transport block is divided into a primary transport subblock and a secondary transport subblock. The primary transport sub-block contains indication information for the secondary transport sub-block or transport block. The UE may learn the size of the secondary transmission sub-block or determine whether there is a secondary transmission sub-block according to the received primary transmission sub-block. If there is no secondary transmission sub-block, the UE only needs to receive the primary transmission sub-block.

Please refer to FIG. 4b, which is a structural diagram of another transport block according to an embodiment of the present invention. Taking a transport block carrying indication information as an example, and the transport block is divided into three different implementations of the transport sub-block.

Mode 1: The transport block is divided into three transport sub-blocks, and each transport sub-block carries indication information. In particular, the transmission sub-block 1 carries indication information for the transmission sub-block 2. The transmission sub-block 2 carries indication information for the transmission sub-block 3. The transmission sub-block 3 may carry indication information of the transport block. For example, the transmission sub-block 3 carries indication information that the transmission sub-block is the last transmission sub-block. The content of the indication information carried by different transmission sub-blocks may be different.

Mode 2: The transport block is divided into three transport sub-blocks, and the last transport sub-block does not carry indication information. The transmission sub-block 1 carries indication information for the transmission sub-block 2. The transmission sub-block 2 carries indication information for the transmission sub-block 3. The transmission sub-block 3 does not carry the indication information, which may indicate that the transmission sub-block 3 is the last transmission sub-block. The indication information in the transmission sub-block 2 may indicate that the transmission sub-block 3 is the last transmission sub-block.

Mode 3: The transport block is divided into three transport sub-blocks, and only the first transport sub-block carries indication information. The transmission sub-block 1 carries indication information for the transmission sub-block 2 and the transmission sub-block 3. The indication information in the transmission sub-block 1 may also indicate the number of transmission sub-blocks.

FIG. 4 is a schematic structural diagram of another transport block according to an embodiment of the present invention. The transport block carries indication information as an example, and the transport block is divided into three transport sub-blocks. Implementation.

Mode 1: The transport block is divided into 3 code blocks. The code block 1 and the indication information constitute the transmission sub-block 1. The code block 2 and the indication information constitute the transmission sub-block 2. The code block 3 and the indication information constitute the transmission sub-block 3. The transmission sub-block 1 carries indication information for the transmission sub-block 2. The transmission sub-block 2 carries indication information for the transmission sub-block 3. The transmission sub-block 3 may carry indication information of the transport block. The content of the indication information carried by different transmission sub-blocks may be different.

Mode 2: The transport block is divided into 3 code blocks. The code block 1 and the indication information constitute the transmission sub-block 1. The code block 2 and the indication information constitute the transmission sub-block 2. The code block 3 constitutes a transmission sub-block 3. The transmission sub-block 1 carries indication information for the transmission sub-block 2. The transmission sub-block 2 carries indication information for the transmission sub-block 3. The transmission sub-block 3 does not carry the indication information, which may indicate that the transmission sub-block 3 is the last transmission sub-block. The indication information in the transmission sub-block 2 may indicate that the transmission sub-block 3 is the last transmission sub-block.

Mode 3: The transport block is divided into 3 code blocks. The code block 1 and the indication information constitute the transmission sub-block 1. The code block 2 constitutes a transmission sub-block 2. The code block 3 constitutes a transmission sub-block 3. The transmission sub-block 1 carries indication information for the transmission sub-block 2 and the transmission sub-block 3.

Taking the information carried by the transport block as a system information block (SIB) as an example, when a transport block (TB) is divided into three transport sub-blocks, it describes how the UE receives the transport block of the SIB. When receiving the SIB, the UE does not know the TBS of the transport block carrying the SIB. However, the transport block carrying the SIB is divided into three transport sub-blocks, and the partitioning method of the transport block to the transport sub-block is as described above. The size of the first transmitted sub-block is known when the UE receives the first transmitted sub-block. For example, the size of the first transmission sub-block is fixed in advance or notified to the UE in advance through the main information block.

The first transmission sub-block contains indication information for the second transmission sub-block. When the UE detects the first transmission sub-block, it obtains the indication information of the second transmission sub-block in the first transmission sub-block. According to the foregoing indication information, the UE can determine the size of the second transmission sub-block. The UE receives the second transmission sub-block according to the determined size of the second transmission sub-block. Similarly, if the second transmission sub-block contains indication information for the third transmission sub-block. After detecting the second transmission sub-block, the UE learns the indication information of the third transmission sub-block in the second transmission sub-block. According to the foregoing indication information, the UE may determine the size of the third transmission sub-block, and receive the third transmission sub-block according to the determined size of the third transmission sub-block. The UE combines the information contained in the received three transmission sub-blocks to obtain the SIB information carried by the SIB transmission block.

Alternatively, the first transport sub-block contains indications for the second transport sub-block and the third transport sub-block. When the UE detects the first transmission sub-block, it obtains the indication information of the second transmission sub-block and the third transmission sub-block in the first transmission sub-block. According to the foregoing indication information, the UE can determine the sizes of the second transmission sub-block and the third transmission sub-block. The UE receives the second transmission sub-block and the third transmission sub-block according to the determined sizes of the second transmission sub-block and the third transmission sub-block. The UE combines the information contained in the received three transmission sub-blocks to obtain the SIB information carried by the SIB transmission block.

Specifically, in the present invention, the SIB may be SIB1, or SIB1 of a low complexity UE, or SIB1 of a new UE type, or an SIB of a new UE type.
