Description

System information message transmission method, terminal and network equipment

Technical Field

The present invention relates to the field of communications technologies, and in particular, to a system information message transmission method, a terminal, and a network device.

Background

In the fourth generation (4)^thGeneration, 4G) mobile communication System, or called Long Term Evolution (LTE) System, network devices compose System Information messages (SI messages) from different System Information Blocks (SIB), and select a suitable time-frequency position in a transmission window corresponding to the System Information for broadcasting. The system information can be divided into various types of SIBs according to the purpose and content, such as: an SIB1 indicating whether the terminal is allowed to access scheduling information of a cell and other SIBs, an SIB2 indicating information of common and shared channels, an SIB3 indicating cell reselection information related to a current serving cell, an SIB4 indicating same-frequency reselection information related to a current serving frequency point, an SIB5 indicating same-system different-frequency reselection information, and the like.

As shown in fig. 1, a transmission cycle of the SIB1 is 80ms, the network device repeatedly transmits the SIB 14 times within 80ms, and transmits the SIB once every 20ms, where a transmission position is a subframe 5 in a System Frame with an even System Frame Number (SFN), and contents of System information transmitted 4 times in the same transmission cycle are the same, and Hybrid Automatic Repeat reQuest (HARQ) combining may be performed. Wherein, 1 system frame includes 10 subframes, which are numbered from 0 to 9, the duration of one system frame is 10ms, in fig. 1, "F" represents initial transmission, and "R" represents retransmission.

In addition to the SIB1, each SIB has a certain transmission period, such as 80ms, 160ms, 320ms, etc., and the transmission period of each SIB is configurable and notified to the terminal by the network device. The plurality of SIBs with the same transmission period may form one SI message to be transmitted, each SI message is transmitted in a predetermined time window, or referred to as an SI transmission time window (SI-window), and the SI messages and the transmission time windows are in one-to-one correspondence, that is, one SI message corresponds to one transmission time window, and only one SI message is transmitted in one transmission time window. The time lengths of the transmission time windows of the SI messages are configurable, but the time lengths of the transmission time windows of all the SI messages in a cell (cell) are consistent, and the transmission time windows of different SI messages are connected end to end. Further, within the transmission time window, the network device may select one or more subframes for SI message transmission, and the transmitted SI message may be HARQ combined. It is worth pointing out that other SI messages cannot be transmitted in the transmission subframe of SIB1, i.e. other SI messages cannot be transmitted in subframe 5 of even system frames.

In the scheduling information, the network equipment indicates the length w of the transmission time window, a list of SI messages (the order of each SI message in the list is denoted by n, n starts with 1), and a repetition period T of each SI message. Then x corresponding to the SI message n can be obtained by the formula x ═ n-1 × w; the initial system frame of the SI message n transmission time window satisfies SFN% T ═ FLOOR (x/10), and the initial subframe is x% 10; the value of the SFN ranges from 0 to 1023. Wherein, in the above formula: % represents the remainder of the division, and FLOOR represents the integer portion of the calculation.

Assuming that the length of the transmission time window is 5 subframes, the SIB2 and the SIB3 form an SI Message1, the transmission period is 160ms, the SIB4 and the SIB5 form an SI Message2, the transmission period is 320ms, the SIB6 forms an SI Message3, the transmission period is 320ms, the SIB7 and the SIB8 form an SI Message4, and the transmission period is 640 ms. As shown in fig. 2, the SI message1 corresponds to the first SI-window, i.e., SI-window1, and in 5 subframes of the SI-window1, the network device may optionally select one or more subframes for transmitting the SI message 1. Wherein:

for SI message1, x ═ 0 ═ 5 ═ 1-1; SFN satisfying the formula SFN% 16 ═ FLOOR (0/10) takes integer multiples of 16 such as 0,16,32,48 … …, etc.; the starting subframe is 0% 10 ═ 0, i.e., the transmission time window of SI message1 starts from the 0 th subframe of the system frame with SFN value of an integer multiple of 16, such as 0,16,32,48 … …, etc.

Similarly, for SI message2, x ═ 5 (2-1); SFN satisfying the formula SFN% 32 ═ FLOOR (5/10) takes integer multiples of 32 such as 0,32,64,96 … …, etc.; the transmission time window with the starting subframe of 5% 10 ═ 5, i.e., SI message2, starts with the 5 th subframe of the system frame with SFN value of an integer multiple of 32, such as 0,32,64,96 … …, etc.

Similarly, for SI message3, x ═ 10 ═ 5 ═ 3-1; the SFN satisfying the formula SFN% 32 ═ FLOOR (10/10) takes the integer multiple of 32 such as 1,33,65,97 … …, and the like, plus 1; the transmission time window with the start subframe 10% 10 ═ 0, i.e. SI message3, starts from the 0 th subframe of the system frame with SFN value 0,33,65,97 … …, etc. 32, integer times 1.

Similarly, for SI message4, x ═ 15 (4-1) × (5); the SFN satisfying the formula SFN% 64 ═ FLOOR (15/10) takes the integer multiple of 64 such as 1,65,129,193 65,129,193 … … and the like plus 1; the transmission time window with the starting subframe of 15% 10 ═ 5, i.e. SI message4, starts with the 5 th subframe of the system frame with SFN value 1, integer multiple of 64, such as 65,129,193 65,129,193 … …, plus 1.

In the fifth generation (5)^thGeneration, 5G) mobile communication system, or referred to as New Radio (NR) system, the services supported by the system are richer than those of the 4G system, and more types of SIBs need to be supported, and accordingly, more transmission time windows need to be reserved in the SI message transmission period to ensure transmission of the SIBs, which inevitably results in increase of the number of the transmission time windows. In addition, the 5G system operates in a higher frequency band, and in order to overcome the large path loss of high frequency, the transmission may be performed in a multi-beam manner, for example, 16 beams are used to cover a 360-degree range cell, and each beam only needs to cover a range of a small angle (e.g., 22.5 degrees). The different beams are transmitted in a time division multiplexing mode, if the network equipment transmits the system information message in the same mode as that in the traditional 4G system, the network equipment transmits the system information message in the same mode as that in the traditional 4G systemThe length of the transmission time window is larger if the transmission time window of an SI message includes at least 16 subframes to ensure that each beam has a transmission opportunity, and in addition, to ensure transmission reliability, a certain repetition transmission opportunity needs to be reserved for each beam in each window. Thus, in a 5G system, the sum of the lengths of the transmission time windows of all SI messages exceeds the minimum repetition transmission period (e.g. 160ms) of the SI messages, so that the system cannot guarantee that there is one transmission time window available for each transmission period for each SI message.

It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments of the application described herein are, for example, capable of operation in sequences other than those illustrated or otherwise described herein. Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.

An embodiment of the present invention provides a system information message transmission method, which is applied to a terminal side, and as shown in fig. 3, the method specifically includes the following steps:

step 31: at least one system information, SI, message corresponding to a transmission time window is received through the transmission time window.

Wherein the at least one SI message comprises: and sending the SI messages with the same period and/or sending the SI messages with different periods. The network device maps at least one SI message to one transmission time window, that is, the network device maps one SI message to one transmission time window, and different SI messages may be mapped to the same transmission time window, that is, the network device maps each SIB packet to one transmission time window, but different SIB packets may be mapped to the same transmission time window. The SI messages transmitted in the same transmission time window have the same transmission period, and may also have different transmission periods.

Specifically, in the method for transmitting a system information message according to the embodiment of the present invention, before step 31, the method further includes: receiving scheduling information sent by network equipment; the scheduling information includes: mapping relationship between system information SI message and transmission time window. Step 31 specifically includes: and receiving the corresponding SI message through one transmission time window according to the mapping relation between the SI message and the transmission time window in the scheduling information. Wherein at least one SI message corresponds to a transmission time window. Wherein the scheduling information may be transmitted to the terminal through SIB 1.

The step of receiving the corresponding SI message through one transmission time window according to the mapping relationship between the SI message and the transmission time window in the scheduling information includes: acquiring a window index number of a transmission time window corresponding to the SI message according to the scheduling information; and receiving the corresponding SI message through the transmission time window corresponding to the window index number according to the mapping relation between the SI message and the transmission time window. Wherein one window index number corresponds to one transmission time window. That is, the terminal decodes the scheduling information sent to the Radio Network Temporary Identity (RNTI) within the transmission time window, and receives the SI message at the time-frequency resource position indicated by the scheduling information. The terminal may obtain the time domain position of the transmission time window in a predefined manner based on the window index number and the transmission period of the SI message, where the predefined method may be a predefined calculation formula. Namely, the terminal can calculate the time domain position of the transmission time window through a preset calculation formula according to the window index number and the sending period of the SI message.

Specifically, taking window index number q, window length w, and transmission period T of the SI message as input parameters, the preset calculation formula is: y is (q-1) w, and y corresponding to the window index q is a calculation intermediate quantity; the starting system frame of the transmission time window with the window index number q meets SFN% T ═ FLOOR (y/10), and the starting subframe is y% 10; the value range of the SFN is 0 to 1023, and the time domain position corresponding to the transmission time window is calculated, so that the terminal can receive the SI message at the determined time domain position. It should be noted that the SFN refers to the system frame number, and the time domain position of other units, such as the timeslot number where the transmission time window is located, the micro timeslot number, etc., can also be calculated by the above formula. Assuming that the length of the transmission time window is 5 subframes, the index numbers of the transmission time windows corresponding to SI message1 and SI message2 are both 1, and the transmission periods are both 160ms, y is (1-1) × 5 is 0, the SFN satisfying the formula SFN% 16 ═ FLOOR (0/10) is an integer multiple of 16, such as 0,16,32,48 … …, and the starting subframe is 0% 10 ═ 0, that is, the transmission time windows of SI message1 and SI message2 are all started from the 0 th subframe of the system frame whose SFN is an integer multiple of 16, such as 0,16,32,48 … …. Or, assuming that the length of the transmission time window is 5 sub-frames, the index numbers of the transmission time windows corresponding to the SI message1 and SI message2 are both 1, however, if the transmission period of the SI message1 is 160ms and the transmission period of the SI message2 is 320ms, y is (1-1) × 5 is 0, SFN satisfying the formula SFN% 16 ═ FLOOR (0/10) is an integer multiple of 16 such as 0,16,32,48 … …, and the initial subframe is 0% 10 ═ 0, that is, the transmission time window of the SI message1 starts from the 0 th subframe of the system frame whose SFN is an integer multiple of 16, such as 0,16,32,48 … …, etc., the SFN satisfying the formula SFN% 32FLOOR (0/10) is an integer multiple of 32, such as 0,32,64,128 64,128 … …, etc., the starting subframe is 0% 10 ═ 0, i.e., the transmission time window of the SI message2, begins with the 0 th subframe of the system frame having SFN of an integer multiple of 32, such as 0,32,64,128 64,128 … …, etc.

Further, the terminal may also obtain the time lengths of the transmission time windows according to the scheduling information, specifically, the time length of each transmission time window may be notified in the SIB1, and the time lengths of the transmission time windows may be different or may be the same.

Further, the window index number may be obtained in an implicit indication manner and an explicit indication manner, where the implicit indication manner may refer to the following manner: determining the occurrence sequence of the SI message sets mapped to the same transmission time window according to the scheduling information; and determining the window index number corresponding to the transmission time window according to the appearance sequence of the SI message set. Specifically, the occurrence order of the SI message sets mapped to the same transmission time window may be determined as the window index number of the corresponding transmission time window, for example, if the SI message1 and the SI message2 mapped to the same transmission time window form the SI message set 1, and the occurrence order in the scheduling information is 1, then the SI message1 and the SI message2 are mapped to the transmission time window with the window index number of 1.

Further, the explicit indication mode is directly obtained through the scheduling information, and specifically, the scheduling information further includes: the first indication information is used for indicating the window index number of the transmission time window corresponding to the SI message, and/or the second indication information is used for indicating whether the window index number of the transmission time window corresponding to the current SI message is the same as the window index number of the transmission time window corresponding to the previous SI message.

Two different acquisition modes are further described below:

in the first mode, the terminal acquires the window index number through the first indication information in the scheduling information.

The method is that a group of window Index numbers (window indexes) is predefined by a protocol, and one transmission time window corresponds to one window Index number. Wherein the first indication information comprises at least one indication bit, and different combination values of the at least one indication bit are used for indicating different window index numbers, i.e. for indicating different transmission time windows. The number of the indication bits of the window Index depends on how many transmission time windows are supported in the cell, i.e., the number of the indication bits included in the first indication information is determined according to the number of the most supported transmission time windows. For example, a cell supports 4 transmission time windows, the first indication information includes 2 indication bits to identify all window indexes; if the cell supports 6 transmission time windows, the first indication information needs 3 indication bits to identify the entire window Index. For the convenience of terminal identification, the time lengths of the transmission time windows supported by each cell are all the same.

The scheduling information carrying the first indication information may be sent through the SIB1, and when the sending periods of the SI messages in at least one SI message transmitted in one transmission time window are the same, specifically, the signaling format of the SIB1 may refer to the following signaling design:

as above, the SI message2 and the SI message3 are mapped to the same transmission time window (window Index2) for transmission, and the transmission periods of the SI message2 and the SI message3 are both 320 ms.

Alternatively, the signaling format of SIB1 may also be designed with reference to the following signaling:

as described above, the SI message2 and the SI message3 with the sending periods of 320ms are mapped to the same transmission time window (window Index of 2) for transmission, and the configuration of the SI message2 and the SI message3 is completed in the configuration signaling of the transmission time window (window Index of 2), which can save signaling overhead and is easy to expand.

Further, when the transmission period of the SI message in the at least one SI message transmitted within one transmission time window is different, the signaling format of the SIB1 may be specifically designed with reference to the following signaling:

as above, the SI message3 and the SI message4 are mapped to the same transmission time window (window Index3) for transmission, and the transmission periods of the SI message3 and the SI message4 are different, one transmission period is 320ms, and the other transmission period is 640 ms. It should be noted that, in order to save signaling overhead, the signaling format of the scheduling information of the SIB1 can also be implemented in a manner referred to the above transmission window configuration.

And in the second mode, the terminal acquires the window index number through second indication information in the scheduling information.

Wherein, the method predefines a window Index number (window Index) for the protocol, and the window Index number is the initial window Index number. The second indication information is used to indicate a window index number of a transmission time window corresponding to the first occurring SI message in the scheduling information, where the window index number is an initial window index number, such as 0 or 1. The second indication information is further used to indicate whether the window index number of the transmission time window corresponding to the subsequently occurring SI message is the same as the window index number of the transmission time window corresponding to the previous SI message, i.e., indicate whether the subsequently occurring SI message is mapped to a new transmission time window.

Specifically, the second indication information includes 1 indication bit, and the second indication information is used to indicate a window index number of a transmission time window corresponding to the first occurring SI message in the scheduling information, and if the value of the indication bit is 0, the initial window index number is indicated to be 0, and the value of the indication bit is 1, and the initial window index number is indicated to be 1. If the second indication information indicates that the window index number of the transmission time window corresponding to the current SI message is the same as the window index number of the transmission time window corresponding to the previous SI message, the window index number of the transmission time window corresponding to the previous SI message is determined as the window index number of the transmission time window corresponding to the SI message. Specifically, the second indication information includes 1 indication bit for indicating whether the current SI message is mapped to a new transmission time window (new window), and when the value of the indication bit (e.g. the value of the indication bit is 0/False) indicates that the current SI message is not the new window, the SI message and the previous SI message (here, before and after refer to the occurrence order in the scheduling information) are mapped to the same transmission time window, that is, the window index number of the transmission time window corresponding to the SI message is the same as the window index number of the transmission time window corresponding to the previous SI message.

Or, if the second indication information indicates that the window index number of the transmission time window corresponding to the current SI message is different from the window index number of the transmission time window corresponding to the previous SI message, the window index number of the transmission time window corresponding to the previous SI message is shifted by a preset offset, and the shifted index number is determined as the window index number of the transmission time window corresponding to the SI message. Specifically, when the value of the indication bit (e.g., the value of the indication bit is 1 or True) indicates new window, the SI message and the previous SI message (where before and after refer to the occurrence order in the scheduling information) are mapped into different transmission time windows, and then the window index number of the transmission time window corresponding to the SI message is offset from the window index number of the transmission time window corresponding to the previous SI message by a preset offset, and if the offset is 1, the window index number of the transmission time window corresponding to the SI message is window index +1 of the previous SI message.

Further, the scheduling information carrying the first indication information and the second indication information may be sent through the SIB1, and when the sending periods of the SI messages in at least one SI message transmitted in one transmission time window are the same, specifically, the signaling format of the SIB1 may be designed with reference to the following signaling:

the indication bits in the second indication information used for indicating whether the current SI message is the same as the window index number of the transmission time window corresponding to the previous SI message may be set discretely, or the newwindows indexes of multiple messages may be put together to form a bit string and put in the Sib-mapping info.

Further, step 31 further comprises: acquiring System Information Radio Network Temporary Identity (SI-RNTI) Information; and receiving at least one SI message corresponding to the transmission time window according to the SI-RNTI information in one transmission time window.

Wherein the SI-RNTI information is used to indicate at least one SI-RNTI associated with the same transmission time window, in particular the protocol specifies one or a group of SI-RNTIs for transmission of SI messages.

Specifically, when the SI-RNTI information indicates that one SI-RNTI is associated with the same transmission time window, i.e., the protocol specifies one SI-RNTI for transmission of the SI message, a first SI message of the at least one SI message corresponding to the transmission time window is received through the SI-RNTI within one transmission time window. And reserving certain SI-X-RNTI for each cell by the SI-RNTI offset N-1 in the transmission time window, namely, the protocol provides that each cell receives the N-th SI message in at least one SI message corresponding to the transmission time window. N is an integer greater than 1. Wherein, it is worth pointing out that the SI-X-RNTI refers to a system information radio network temporary identifier after the SI-RNTI is offset. For example: the protocol specifies an SI-RNTI for receiving the SI message, and the terminal calculates the RNTI corresponding to the SI message for receiving through a preset calculation mode based on the SI-RNTI. For a transmission time window in which only one SI message is transmitted, the terminal may directly receive the corresponding SI message using the SI-RNTI. For the transmission time window for transmitting at least two SI messages, the terminal can use the SI-RNTI to receive the first appearing SI message in the scheduling information according to the appearance sequence of the SI messages in the scheduling information; the SI message that occurs second in the scheduling information is received using SI-RNTI +1, and so on.

It is worth pointing out that the nth SI message refers to: and the Nth occurrence SI in the SI message set mapped to the same transmission time window in the scheduling information. Wherein, the SI message set refers to a set of at least one SI message mapped to the same transmission time window in the scheduling information.

Further, when the SI-RNTI information indicates at least two SI-RNTIs associated with the same transmission time window, an Mth SI message of the at least one SI message corresponding to the transmission time window is received through an Mth SI-RNTI of the at least two SI-RNTIs within one transmission time window. Wherein M is an integer greater than or equal to 1. For example, the system defines a set of SI-RNTIs, including: SI-RNTI1, SI-RNTI2, … and SI-RNTI M. For a transmission time window in which only one SI message is transmitted, the terminal may receive the corresponding SI message using SI-RNTI 1. For a transmission time window for transmitting at least two SI messages, the terminal receives the SI message appearing first in the scheduling information by using the SI-RNTI1 according to the appearance sequence of the SI messages in the scheduling information; the SI message that occurs second in the scheduling information is received using SI-RNTI2, and so on.

In the system information message transmission method of the embodiment of the invention, the terminal can receive at least one SI message required by the terminal through one transmission time window, thereby effectively reducing the number of the transmission time windows, shortening the total length of the transmission time windows and ensuring that each SI message in each sending period has the available transmission time window.
