Description
Technical Field
The present invention relates to paging processing technology in the field of communications, and in particular, to an information transmission method, an information reception method, a network device, a terminal device, and a storage medium.
Background
The eMTC technology is introduced into the R13 edition of LTE network evolution facing the application of the Internet of things. The basic technical principle is that on the basis of an LTE network, technologies such as repeated transmission and support of narrow bandwidth are introduced, and low-power-consumption application of the Internet of things is better supported. Due to the above requirements, the system broadcast messages (MIB, SIB) of LTE have certain changes, and the MIB message of version R13 (carried by PBCH) has a new definition of the previously reserved fields in the MIB message compared to version R8. It can be seen that a MIB of R13 defines a 5-bit schedulingInfoSIB1-BR-R13, which is used to characterize that the cell supports eMTC terminal access and indicate scheduling information of a subsequent SIB 1-BR.
Since the MIB message is critical, it indicates the cell bandwidth, SFN, and other basic cell configuration information. However, at present, some LTE old terminals only recognize MIB messages that are not expanded in the R8 phase, and new terminals can recognize system messages containing eMTC-related information for R13, which may cause compatibility problems of the old terminals.

Detailed Description
The invention is described in further detail below with reference to the figures and specific examples.
The first embodiment,
An embodiment of the present invention provides an information transmission method, which is applied to a network device, and as shown in fig. 1, the method includes:
step 101: in a system information sending period, determining the sending position of a first-class master information block MIB and the sending position of a second-class MIB;
step 102: sending a first-class master information block MIB at the sending position of the first-class MIB and sending a second-class MIB at the sending position of the second-class MIB; wherein the first MIB is different from the second MIB.
Here, the scheme provided by this embodiment may be applied in an LTE system, and may be particularly directed to an eMTC terminal device. By the scheme, especially for eMTC supported by LTE, terminal compatibility problem possibly caused by need of MIB message field expansion can be solved; the scheme that the MIB messages are kept consistent in the system information transmission period (40ms period) can be broken, and a new MIB message broadcast transmission scheme and a terminal demodulation scheme are provided.
The system information sending period may be 40 milliseconds (ms), and of course, other lengths may also be provided according to actual system settings, which is not limited in this embodiment.
Setting unexpanded MIB information in a first data area in the first MIB, and setting 0 in a second data area; for example, the MIB of the first type may be considered to hold the information of stage R8, i.e. the 10 bits held (spare part) are still 0.
And the second MIB at least carries the 13 th version scheduling information. Namely, part of the MIB information is replaced by the scheduling information of SIB1 of version 13, namely, the MIB message carrying schedulingInfoSIB 1-BR-R13.
As to how to determine the transmission positions of different MIBs, the present embodiment may provide the following two schemes:
scheme 1, alternate transmission scheme within 10ms period:
specifically, the determining the transmission position of the first-type master information block MIB and the transmission position of the second-type MIB in the system information transmission period includes:
in at least one sub-sending period in the system information sending period, each sending sub-period determines at least two information repetition positions;
determining a first information repetition position in at least two information repetition positions in each sending sub-period as a sending position of a first MIB;
and determining the repeated positions of other information except the first repeated position of the information in at least two repeated positions of the information in each transmission sub-period as the transmission positions of the second type MIB.
For example, for a specific MIB scheme transmitted within 40ms, the position of Repetition0 is the transmission position of the first-type MIB, and the positions of Repetition 1-4 are the transmission positions of the second-type MIB.
The specific transmission scheme is as follows:
for an LTE cell supporting R13eMTC, the MIB sending mode is expanded to 5 times within 10ms, namely, the at least two information Repetition positions are set to be 5, and the positions can be expressed as Repetition 0-4 positions specifically; the whole system information transmission period can be a 40ms period, and the transmission is performed 50 times in the 40ms period.
Correspondingly, a first-class master information block MIB is sent at the sending position of the first-class MIB, and a second-class MIB is sent at the sending position of the second-class MIB; the first MIB and the second MIB are different and may be:
for the specific MIB scheme sent within 40ms, the MIB message sent at the position of repetition0 is kept at stage R8, i.e. 10 bits are kept still at 0 (e.g. spare part shown in fig. 2), denoted MIB (a), i.e. MIB of the first type.
For example, the MIB of the first type may be shown in fig. 2, where a spare field is a character string and has a length of 10 bits; then, system frame number is shown through a system frame number field, and the length of the system frame number is 8 bits; and the dl-Bandwidth indicates that the MIB is downlink information.
For the MIB messages at Repetition 1-4 positions, the MIB messages at stage R13 are replaced, for example, as shown in fig. 3, the MIB messages carrying schedulingInfoSIB1-BR-R13 in the MIB information are denoted as MIB (b) -i.e., a second type MIB.
Scheme 2: alternate transmission scheme between 10 × N/10 × M ms:
the determining the sending position of the first type master information block MIB and the sending position of the second type MIB in the system information sending period comprises the following steps:
dividing the system information sending period to obtain at least one first sub-period and at least one second sub-period;
taking at least two information repetition positions in the first sub-period as sending positions of a first MIB;
and taking at least two information repetition positions in the second sub-period as the sending positions of the second MIB.
In this scheme, the system information transmission period may be divided into at least two sub-periods, and the at least two sub-periods occur alternately.
Specifically, the length of the first sub-period is N times of 10 milliseconds, and the length of the second sub-period is M times of 10 milliseconds; n, M are positive numbers, N + M is less than or equal to 4, and M is greater than N.
For example, the length of the system information sending period is 40ms, the length of the first sub-period is 10ms, and the length of the second sub-period is 20 ms; one system information transmission period includes two first sub-periods and one second sub-period, and the distribution may be from the first sub-period to the second sub-period to the first sub-period.
The specific transmission scheme is as follows:
for an LTE cell supporting R13eMTC, the MIB transmission mode is still expanded to 5 times within 10ms, and 50 times within a 40ms period;
for a specific MIB scheme sent within 10 × N ms (N is a natural number), keeping an MIB message sent at a position of repetition 0-4 to be in a stage of R8, namely keeping 10 bits still to be 0(spare part), and marking as MIB (A) (first type MIB);
for a specific MIB scheme sent within 10 × M ms (M is a natural number), replacing the MIB messages at the Repetition 0-4 position with MIB messages at the stage of R13, namely the MIB messages carrying scheduling InfoSIB1-BR-R13, and recording as MIB (B) (a second type of MIB); n + M is less than or equal to 4, and M is greater than N.
Therefore, by adopting the scheme, different MIB information contents are transmitted in one system information transmission period; therefore, different types of terminal equipment can be ensured to acquire the corresponding MIB information content, the system is ensured to be compatible with different types of terminal equipment, and the normal work of the different types of terminal equipment is ensured. And further, the condition that the LTE terminal can not normally reside in the LTE cell is avoided.
Example II,
The embodiment provides an information receiving method, which is applied to terminal equipment and comprises the following steps: receiving a first-class master information block MIB or a second-class MIB in a system information sending period; wherein the first MIB is different from the second MIB.
Here, the scheme provided by this embodiment may be applied in an LTE system, and may be particularly directed to an eMTC terminal device. By the scheme, especially for eMTC supported by LTE, terminal compatibility problem possibly caused by need of MIB message field expansion can be solved; the scheme that the MIB messages are kept consistent in the system information transmission period (40ms period) can be broken, and a new MIB message broadcast transmission scheme and a terminal demodulation scheme are provided.
The system information sending period may be 40 milliseconds (ms), and of course, other lengths may also be provided according to actual system settings, which is not limited in this embodiment.
Setting unexpanded MIB information in a first data area in the first MIB, and setting 0 in a second data area; for example, the MIB of the first type may be considered to hold the information of stage R8, i.e. the 10 bits held (spare part) are still 0.
And the second MIB at least carries the 13 th version scheduling information. Namely, part of the MIB information is replaced by the MIB message of the R13 stage, namely the MIB message carrying schedulingInfoSIB 1-BR-R13.
As to how to receive MIB information, the present embodiment may provide the following scheme:
for an old LTE terminal, in at least one sub-transmission period contained in the system information transmission period and at least two information resetting positions of each transmission sub-period, a first type MIB of a first information resetting position is identified.
Since only the MIB messages of the repetition0 position need to be identified as specified by the protocol. For scheme one, the alternate transmission scheme repeption 0 position in 10ms is consistent with the R8 phase, so old terminals can always demodulate MIB messages correctly.
For an eMTC new terminal, there are two implementation schemes:
scheme 1: and identifying the second-type MIB of the rest information repetition positions except the first information repetition position in at least one sub-transmission period contained in the system information transmission period and at least two information repetition positions of each transmission sub-period.
The method further comprises the following steps: merging the second MIBs identified from the rest information repeated positions to obtain a target MIB; and when the target MIB contains the indication information aiming at the SIB, receiving and demodulating the SIB.
The eMTC terminal does not demodulate the MIB messages at the original repetition0 position, demodulates the MIB messages at the repetition 1-4 positions within 40ms and merges the MIB messages, and continues to demodulate the subsequent SIB broadcast messages and the like if the scheduling information SIB1-BR-R13 field defined by R13 exists;
scheme 2: and receiving and demodulating the first MIB or the second MIB at least two information repetition positions of the system information sending period.
That is, the eMTC terminal combines all the MIB messages at the repetition 0-4 positions within 40ms, and combines and demodulates the MIB messages depending on the terminal.
Therefore, by adopting the scheme, different MIB information contents are transmitted in one system information transmission period; therefore, different types of terminal equipment can be ensured to acquire the corresponding MIB information content, the system is ensured to be compatible with different types of terminal equipment, and the normal work of the different types of terminal equipment is ensured.
Example III,
An embodiment of the present invention provides a network device, as shown in fig. 4, where the network device includes:
a processing unit 41, configured to determine a sending position of a first-type master information block MIB and a sending position of a second-type MIB in a system information sending period;
a transmitting unit 42, configured to transmit a first-type master information block MIB at a transmission position of the first-type MIB and transmit a second-type MIB at a transmission position of the second-type MIB; wherein the first MIB is different from the second MIB.
Here, the scheme provided by this embodiment may be applied in an LTE system, and may be particularly directed to an eMTC terminal device. By the scheme, especially for eMTC supported by LTE, terminal compatibility problem possibly caused by need of MIB message field expansion can be solved; the scheme that the MIB messages are kept consistent in the system information transmission period (40ms period) can be broken, and a new MIB message broadcast transmission scheme and a terminal demodulation scheme are provided.
The system information sending period may be 40 milliseconds (ms), and of course, other lengths may also be provided according to actual system settings, which is not limited in this embodiment.
Setting unexpanded MIB information in a first data area in the first MIB, and setting 0 in a second data area; for example, the MIB of the first type may be considered to hold the information of stage R8, i.e. the 10 bits held (spare part) are still 0.
And the second MIB at least carries the 13 th version scheduling information. Namely, part of the MIB information is replaced by the MIB message of the R13 stage, namely the MIB message carrying schedulingInfoSIB 1-BR-R13.
As to how to determine the transmission positions of different MIBs, the present embodiment may provide the following two schemes:
scheme 1, alternate transmission scheme within 10ms period:
specifically, the processing unit 41 is configured to determine at least two information repetition positions in each of at least one sub-transmission period in the system information transmission period;
determining a first information repetition position in at least two information repetition positions in each sending sub-period as a sending position of a first MIB;
and determining the repeated positions of other information except the first repeated position of the information in at least two repeated positions of the information in each transmission sub-period as the transmission positions of the second type MIB.
For example, for a specific MIB scheme transmitted within 40ms, the position of Repetition0 is the transmission position of the first-type MIB, and the positions of Repetition 1-4 are the transmission positions of the second-type MIB.
The specific transmission scheme is as follows:
for an LTE cell supporting R13eMTC, the MIB sending mode is expanded to 5 times within 10ms, namely, the at least two information Repetition positions are set to be 5, and the positions can be expressed as Repetition 0-4 positions specifically; the whole system information transmission period can be a 40ms period, and the transmission is performed 50 times in the 40ms period.
Accordingly, for a specific MIB scheme transmitted within 40ms, the MIB message transmitted at the position of repetition0 remains at stage R8, i.e. 10 bits remain at 0 (e.g. the spare part shown in fig. 2), denoted MIB (a), i.e. MIB of the first type.
For example, the MIB of the first type may be shown in fig. 2, where a spare field is a character string and has a length of 10 bits; then, system frame number is shown through a system frame number field, and the length of the system frame number is 8 bits; and the dl-Bandwidth indicates that the MIB is downlink information.
For the MIB messages at Repetition 1-4 positions, the MIB messages at stage R13 are replaced, for example, as shown in fig. 3, the MIB messages carrying schedulingInfoSIB1-BR-R13 in the MIB information are denoted as MIB (b) -i.e., a second type MIB.
Scheme 2: alternate transmission scheme between 10 × N/10 × M ms:
the processing unit 41 is configured to divide the system information sending period to obtain at least one first sub-period and at least one second sub-period;
taking at least two information repetition positions in the first sub-period as sending positions of a first MIB;
and taking at least two information repetition positions in the second sub-period as the sending positions of the second MIB.
In this scheme, the system information transmission period may be divided into at least two sub-periods, and the at least two sub-periods occur alternately.
Specifically, the length of the first sub-period is N times of 10 milliseconds, and the length of the second sub-period is M times of 10 milliseconds; n, M are positive numbers, N + M is less than or equal to 4, and M is greater than N.
For example, the length of the system information sending period is 40ms, the length of the first sub-period is 10ms, and the length of the second sub-period is 20 ms; one system information transmission period includes two first sub-periods and one second sub-period, and the distribution may be from the first sub-period to the second sub-period to the first sub-period.
The specific transmission scheme is as follows:
for an LTE cell supporting R13eMTC, the MIB transmission mode is still expanded to 5 times within 10ms, and 50 times within a 40ms period;
for a specific MIB scheme sent within 10 × N ms (N is a natural number), keeping an MIB message sent at a position of repetition 0-4 to be in a stage of R8, namely keeping 10 bits still to be 0(spare part), and marking as MIB (A) (first type MIB);
for a specific MIB scheme sent within 10 × M ms (M is a natural number), replacing the MIB messages at the Repetition 0-4 position with MIB messages at the stage of R13, namely the MIB messages carrying scheduling InfoSIB1-BR-R13, and recording as MIB (B) (a second type of MIB); n + M is less than or equal to 4, and M is greater than N.
Therefore, by adopting the scheme, different MIB information contents are transmitted in one system information transmission period; therefore, different types of terminal equipment can be ensured to acquire the corresponding MIB information content, the system is ensured to be compatible with different types of terminal equipment, and the normal work of the different types of terminal equipment is ensured.
Example four,
An embodiment of the present invention provides a network device, as shown in fig. 5, where the network device includes:
a first processor 51, configured to determine a sending position of a first-type master information block MIB and a sending position of a second-type MIB in a system information sending period;
a first communication interface 52 for transmitting a first-type master information block MIB at a transmission position of the first-type MIB and transmitting a second-type MIB at a transmission position of the second-type MIB; wherein the first MIB is different from the second MIB.
Here, the scheme provided by this embodiment may be applied in an LTE system, and may be particularly directed to an eMTC terminal device. By the scheme, especially for eMTC supported by LTE, terminal compatibility problem possibly caused by need of MIB message field expansion can be solved; the scheme that the MIB messages are kept consistent in the system information transmission period (40ms period) can be broken, and a new MIB message broadcast transmission scheme and a terminal demodulation scheme are provided.
The system information sending period may be 40 milliseconds (ms), and of course, other lengths may also be provided according to actual system settings, which is not limited in this embodiment.
Setting unexpanded MIB information in a first data area in the first MIB, and setting 0 in a second data area; for example, the MIB of the first type may be considered to hold the information of stage R8, i.e. the 10 bits held (spare part) are still 0.
And the second MIB at least carries the 13 th version scheduling information. Namely, part of the MIB information is replaced by the MIB message of the R13 stage, namely the MIB message carrying schedulingInfoSIB 1-BR-R13.
As to how to determine the transmission positions of different MIBs, the present embodiment may provide the following two schemes:
scheme 1, alternate transmission scheme within 10ms period:
specifically, the first processor 51 is configured to determine at least two information repetition positions in each of at least one sub-transmission period in the system information transmission period;
determining a first information repetition position in at least two information repetition positions in each sending sub-period as a sending position of a first MIB;
and determining the repeated positions of other information except the first repeated position of the information in at least two repeated positions of the information in each transmission sub-period as the transmission positions of the second type MIB.
For example, for a specific MIB scheme transmitted within 40ms, the position of Repetition0 is the transmission position of the first-type MIB, and the positions of Repetition 1-4 are the transmission positions of the second-type MIB.
The specific transmission scheme is as follows:
for an LTE cell supporting R13eMTC, the MIB sending mode is expanded to 5 times within 10ms, namely, the at least two information Repetition positions are set to be 5, and the positions can be expressed as Repetition 0-4 positions specifically; the whole system information transmission period can be a 40ms period, and the transmission is performed 50 times in the 40ms period.
Accordingly, for a specific MIB scheme transmitted within 40ms, the MIB message transmitted at the position of repetition0 remains at stage R8, i.e. 10 bits remain at 0 (e.g. the spare part shown in fig. 2), denoted MIB (a), i.e. MIB of the first type.
For example, the MIB of the first type may be shown in fig. 2, where a spare field is a character string and has a length of 10 bits; then, system frame number is shown through a system frame number field, and the length of the system frame number is 8 bits; and the dl-Bandwidth indicates that the MIB is downlink information.
For the MIB messages at Repetition 1-4 positions, the MIB messages at stage R13 are replaced, for example, as shown in fig. 3, the MIB messages carrying schedulingInfoSIB1-BR-R13 in the MIB information are denoted as MIB (b) -i.e., a second type MIB.
Scheme 2: alternate transmission scheme between 10 × N/10 × M ms:
the first processor 51 is configured to divide the system information sending period to obtain at least one first sub-period and at least one second sub-period;
taking at least two information repetition positions in the first sub-period as sending positions of a first MIB;
and taking at least two information repetition positions in the second sub-period as the sending positions of the second MIB.
In this scheme, the system information transmission period may be divided into at least two sub-periods, and the at least two sub-periods occur alternately.
Specifically, the length of the first sub-period is N times of 10 milliseconds, and the length of the second sub-period is M times of 10 milliseconds; n, M are positive numbers, N + M is less than or equal to 4, and M is greater than N.
For example, the length of the system information sending period is 40ms, the length of the first sub-period is 10ms, and the length of the second sub-period is 20 ms; one system information transmission period includes two first sub-periods and one second sub-period, and the distribution may be from the first sub-period to the second sub-period to the first sub-period.
The specific transmission scheme is as follows:
for an LTE cell supporting R13eMTC, the MIB transmission mode is still expanded to 5 times within 10ms, and 50 times within a 40ms period;
for a specific MIB scheme sent within 10 × N ms (N is a natural number), keeping an MIB message sent at a position of repetition 0-4 to be in a stage of R8, namely keeping 10 bits still to be 0(spare part), and marking as MIB (A) (first type MIB);
for a specific MIB scheme sent within 10 × M ms (M is a natural number), replacing the MIB messages at the Repetition 0-4 position with MIB messages at the stage of R13, namely the MIB messages carrying scheduling InfoSIB1-BR-R13, and recording as MIB (B) (a second type of MIB); n + M is less than or equal to 4, and M is greater than N.
Therefore, by adopting the scheme, different MIB information contents are transmitted in one system information transmission period; therefore, different types of terminal equipment can be ensured to acquire the corresponding MIB information content, the system is ensured to be compatible with different types of terminal equipment, and the normal work of the different types of terminal equipment is ensured.
Example V,
The present embodiment provides a terminal device, as shown in fig. 6, including: a receiving unit 61, configured to receive a first-type master information block MIB or a second-type MIB in a system information sending period; wherein the first MIB is different from the second MIB.
Here, the scheme provided by this embodiment may be applied in an LTE system, and may be particularly directed to an eMTC terminal device. By the scheme, especially for eMTC supported by LTE, terminal compatibility problem possibly caused by need of MIB message field expansion can be solved; the scheme that the MIB messages are kept consistent in the system information transmission period (40ms period) can be broken, and a new MIB message broadcast transmission scheme and a terminal demodulation scheme are provided.
The system information sending period may be 40 milliseconds (ms), and of course, other lengths may also be provided according to actual system settings, which is not limited in this embodiment.
Setting unexpanded MIB information in a first data area in the first MIB, and setting 0 in a second data area; for example, the MIB of the first type may be considered to hold the information of stage R8, i.e. the 10 bits held (spare part) are still 0.
And the second MIB at least carries the 13 th version scheduling information. Namely, part of the MIB information is replaced by the MIB message of the R13 stage, namely the MIB message carrying schedulingInfoSIB 1-BR-R13.
As to how to receive MIB information, the present embodiment may provide the following scheme:
for an old LTE terminal, in at least one sub-transmission period contained in the system information transmission period and at least two information resetting positions of each transmission sub-period, a first type MIB of a first information resetting position is identified.
Since only the MIB messages of the repetition0 position need to be identified as specified by the protocol. For scheme one, the alternate transmission scheme repeption 0 position in 10ms is consistent with the R8 phase, so old terminals can always demodulate MIB messages correctly.
For an eMTC new terminal, there are two implementation schemes:
scheme 1: and identifying the second-type MIB of the rest information repetition positions except the first information repetition position in at least one sub-transmission period contained in the system information transmission period and at least two information repetition positions of each transmission sub-period.
The terminal device may further include: a demodulation unit 62, configured to combine the second type MIB identified from the remaining information repetition positions to obtain a target MIB; and when the target MIB contains the indication information aiming at the SIB, receiving and demodulating the SIB.
The eMTC terminal does not demodulate the MIB messages at the original repetition0 position, demodulates the MIB messages at the repetition 1-4 positions within 40ms and merges the MIB messages, and continues to demodulate the subsequent SIB broadcast messages and the like if the scheduling information SIB1-BR-R13 field defined by R13 exists;
scheme 2: and receiving and demodulating the first MIB or the second MIB at least two information repetition positions of the system information sending period.
That is, the eMTC terminal combines all the MIB messages at the repetition 0-4 positions within 40ms, and combines and demodulates the MIB messages depending on the terminal.
Therefore, by adopting the scheme, different MIB information contents are transmitted in one system information transmission period; therefore, different types of terminal equipment can be ensured to acquire the corresponding MIB information content, the system is ensured to be compatible with different types of terminal equipment, and the normal work of the different types of terminal equipment is ensured.
Example six,
The present embodiment provides a terminal device, as shown in fig. 7, including: a second communication interface 71, configured to receive a first-type master information block MIB or a second-type MIB in a system information transmission period; wherein the first MIB is different from the second MIB.
Here, the scheme provided by this embodiment may be applied in an LTE system, and may be particularly directed to an eMTC terminal device. By the scheme, especially for eMTC supported by LTE, terminal compatibility problem possibly caused by need of MIB message field expansion can be solved; the scheme that the MIB messages are kept consistent in the system information transmission period (40ms period) can be broken, and a new MIB message broadcast transmission scheme and a terminal demodulation scheme are provided.
The system information sending period may be 40 milliseconds (ms), and of course, other lengths may also be provided according to actual system settings, which is not limited in this embodiment.
Setting unexpanded MIB information in a first data area in the first MIB, and setting 0 in a second data area; for example, the MIB of the first type may be considered to hold the information of stage R8, i.e. the 10 bits held (spare part) are still 0.
And the second MIB at least carries the 13 th version scheduling information. Namely, part of the MIB information is replaced by the MIB message of the R13 stage, namely the MIB message carrying schedulingInfoSIB 1-BR-R13.
As to how to receive MIB information, the present embodiment may provide the following scheme:
for an old LTE terminal, in at least one sub-transmission period contained in the system information transmission period and at least two information resetting positions of each transmission sub-period, a first type MIB of a first information resetting position is identified.
Since only the MIB messages of the repetition0 position need to be identified as specified by the protocol. For scheme one, the alternate transmission scheme repeption 0 position in 10ms is consistent with the R8 phase, so old terminals can always demodulate MIB messages correctly.
For an eMTC new terminal, there are two implementation schemes:
scheme 1: and identifying the second-type MIB of the rest information repetition positions except the first information repetition position in at least one sub-transmission period contained in the system information transmission period and at least two information repetition positions of each transmission sub-period.
The terminal device may further include: a second processor 72, configured to merge the second type MIB identified from the rest information repetition positions to obtain a target MIB; and when the target MIB contains the indication information aiming at the SIB, receiving and demodulating the SIB.
The eMTC terminal does not demodulate the MIB messages at the original repetition0 position, demodulates the MIB messages at the repetition 1-4 positions within 40ms and merges the MIB messages, and continues to demodulate the subsequent SIB broadcast messages and the like if the scheduling information SIB1-BR-R13 field defined by R13 exists;
scheme 2: and receiving and demodulating the first MIB or the second MIB at least two information repetition positions of the system information sending period.
That is, the eMTC terminal combines all the MIB messages at the repetition 0-4 positions within 40ms, and combines and demodulates the MIB messages depending on the terminal.
Therefore, by adopting the scheme, different MIB information contents are transmitted in one system information transmission period; therefore, different types of terminal equipment can be ensured to acquire the corresponding MIB information content, the system is ensured to be compatible with different types of terminal equipment, and the normal work of the different types of terminal equipment is ensured.
