Detailed Description

the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments.

Example one

The system architecture provided by the embodiment of the invention is an M2M system, in the M2M system, if the UE does not correctly receive the SI, the UE cannot perform normal communication, which will affect the experience of the user and cause the stability of the M2M system to be reduced, so that the reliability and correctness of the SI are of great importance to the performance quality of the M2M system.

In the M2M system provided in the embodiment of the present invention, in order to ensure the transmission reliability of the UE located in a place with poor network coverage, a time domain spreading mode may be adopted to enhance the network coverage of the M2M system. As shown in fig. 1, assuming that the area a is an area with better network coverage, the area B is an area with worse network coverage, and the area C is an area with worse network coverage, the area a can ensure the transmission reliability of the UE1 without spreading (the area a may be referred to as a 1X area); the transmission reliability of the UE2 can be guaranteed only by 8 spreading in the B region (the B region may be referred to as an 8X region); the C-region needs to be spread 64 times to ensure the transmission reliability of the UE3 (the C-region may be referred to as a 64X-region).

In the M2M system provided in this embodiment of the present invention, as shown in fig. 2, taking an 8X region as an example, 1 original data frame is 80 milliseconds, 1 new data frame formed after 8 spreading cycles is 80 × 8 — 640 milliseconds, and the new data frame forms 1 superframe after 8 repetitions, where the superframe is 640 × 8 — 5120 milliseconds (5.12 seconds). Wherein, the time length of 1 new data frame is 8 times of the time length of 1 original data frame; the time length of 1 superframe is 8 times that of 1 new data frame and 64 times that of 1 original data frame.

Further, in order to more clearly and completely describe the transmission method of the SI provided by the embodiment of the present invention, the following embodiments are exemplarily illustrated by taking an 8X region in an M2M system as an example. Of course, the embodiments of the present invention include, but are not limited to, 8X region in M2M system, and the transmission method for SI in other regions, such as 16X region, 32X region, and 64X region, etc., is similar to the transmission method for SI in 8X region. In order to describe the SI transmission method provided by the embodiment of the present invention more clearly and conveniently, the data frame mentioned in the following embodiments refers to a new data frame formed after the original data frame is spread for 8 times, where the new data frame may also be referred to as a spread frame.

in the transmission method of the SI provided in the embodiment of the present invention, before the base station broadcasts the SI, the SI needs to be mapped to the physical channel from the logical channel through the transmission channel, and then is sent on the physical channel. Wherein, the logical channel may be a Broadcast Control Channel (BCCH); the transmission channel may be a broadcast channel (BCH, for short); the physical channel may be a Physical Broadcast Channel (PBCH), or a PBCH and a Physical Downlink Shared Channel (PDSCH).

an execution main body of the SI transmission method provided in the embodiments of the present invention may be a base station or a UE, and the base station may specifically be an evolved node base (eNB). The following describes in detail a transmission method of SI according to an embodiment of the present invention, taking a base station and a UE as examples.

an embodiment of the present invention provides a transmission method of an SI, as shown in fig. 3, the method may include:

S101, the base station maps the first SI to the first PBCH.

S102, the base station continuously sends the first SI m times on the first PBCH, wherein m is an integer larger than 1.

in the embodiment of the present invention, as shown in fig. 4, when a base station sends a first SI to a UE, the first SI needs to be mapped to a first PBCH from a BCCH via a BCH. The BCCH is a logical channel, BCH is a transport channel, and the first PBCH is a physical channel.

it should be noted that the transmission method of SI provided by the embodiment of the present invention may be applied to an M2M system, and in order to enable the UE to correctly receive SI in each coverage area in the M2M system, that is, to enhance reliability of SI transmission, the base station needs to repeatedly transmit SI when transmitting SI. For example, in an 8X region, a base station may continuously transmit SI 8 times; in the 16X region, the base station may continuously transmit the SI 16 times; by analogy, in an mX region, a base station may continuously transmit an SI m times, where m may be an integer greater than 1. Specifically, since the method for the base station to send the SI in the mX region is the same as the method for the base station to send the SI in the 8X region in the following embodiments, the method for the base station to send the SI in the 8X region is only taken as an example in this embodiment for description, and further description of other coverage regions will not be repeated.

Optionally, the first SI may specifically be k System Information Blocks (SIBs) in n SIB blocks, where n is a positive integer, k is a positive integer, and k is less than or equal to n. Illustratively, the first SI may be SIB1, SIB2, SIB1, and SIB1 may be a Master Information Block (MIB).

As shown in fig. 5, when the first SI is k SIBs of the n SIBs, the above S102, that is, the base station continuously transmits the first SI m times on the first PBCH may specifically be:

S102a, the base station transmits k SIBs on m × k consecutive data frames on the first PBCH.

Specifically, in S102a, the method for the base station to send k SIBs on m × k consecutive data frames on the first PBCH may be one of the following methods:

(a) The base station continuously sends the ith SIB in the k SIBs from the (mx) (i-1) + 1) th data frame to the (mxi) th data frame in the (mxk) consecutive data frames on the first PBCH, wherein i is a positive integer and i is less than or equal to k.

As shown in fig. 6, assuming that an 8X region is taken as an example, m is 8, one superframe includes 8 data frames, and the numbers of the 8 data frames are data frame No. 1, data frame No. 2, and data frame No. 8 in sequence. The base station continuously transmits the ith SIB (i.e., SIBI) of the k SIBs on the 8x (i-1) +1 th to 8x i th data frames among the 8x k consecutive data frames on the first PBCH.

specifically, after the base station continuously transmits m SIBs, the base station continuously transmits m next SIBs, and so on, and when the base station continuously transmits k SIBs in sequence, that is, the base station continuously transmits each SIB m times separately in sequence, the base station may start the process of transmitting k SIBs next according to the method in (a) above. That is, the base station may periodically transmit k SIBs according to the method of (a) above.

The method in (a) above may facilitate the extension of the first SI, that is, when the first SI needs to be extended, the information extended in the first SI may be directly and repeatedly sent on the first PBCH, and may not affect the transmission of the original information in the first SI.

(b) The base station sends the ith SIB in the k SIBs on the (i + kx (j-1)) data frames in the m x k continuous data frames on the first PBCH; wherein i is a positive integer, j is a positive integer, i is less than or equal to k, and j is less than or equal to m.

as shown in fig. 7, assuming that an 8X system is taken as an example, m is 8, and one superframe includes 8 data frames, and the numbers of the 8 data frames are data frame No. 1, data frame No. 2, and data frame No. 8 in sequence. The base station transmits the ith SIB (i.e., SIBI) of the k SIBs on the (i + kX (j-1) th) data frame of the 8 xk consecutive data frames on the first PBCH.

specifically, after the base station transmits 1 SIB for the first time, the base station continuously transmits 1 SIB for the next time, and so on, after the base station continuously transmits k SIBs for 1 time, the base station continuously transmits k SIBs for the next time, and the base station repeatedly transmits k SIBs for m times, that is, after the base station continuously transmits k SIBs together for m times, the base station may start the process of transmitting k SIBs next time according to the method in (b). That is, the base station periodically transmits k SIBs according to the method of (b) above.

in the method in (b), for the UE with better received signal quality, if the UE correctly receives the first SI sent by the base station for at least 1 time, the UE may not continue to monitor the first PBCH to receive the first SI, so that power consumption of the UE may be saved.

it should be noted that the inclusion of k SIBs in the first SI may be understood as: the k SIBs contain the configuration parameters necessary for the UE to camp on the cell and access the cell. The specific information block included in the first SI may be determined according to actual situations, and the present invention is not limited thereto.

in particular, k can generally take the value 1, 2 or 3. When the value of k is 1, 2, or 3, it indicates that SIB1 (may also be MIB), SIB1-SIB2, or SIB1-SIB3 are required to be sufficient to transmit important parameters (which may be parameters necessary for camping and access) necessary for UE communication, so that when there are many important parameters necessary for UE communication, it is ensured that the UE can completely acquire the parameters.

optionally, when n > k, it is assumed that k SIBs of the n SIBs are understood as the first SI, and n-k SIBs different from the k SIBs of the n SIBs are understood as the second SI; if the time from one continuous transmission of m times of second SI by the base station to the next continuous transmission of m times of second SI by the base station is recorded as the period for the base station to continuously transmit m times of second SI, and the time from one continuous transmission of m times of first SI by the base station to the next continuous transmission of m times of first SI by the base station is recorded as the period for the base station to continuously transmit m times of first SI, the period for the base station to continuously transmit m times of second SI may be the same as the period for the base station to continuously transmit m times of first SI; or the period of the m times of continuous transmission of the second SI by the base station may be an integer multiple of the period of the m times of continuous transmission of the first SI by the base station, which is not limited in the present invention.

For example, the period in which the base station continuously transmits the m times of first SI may be k × time-frequency repetition period, where k is the number of SIBs; the period in which the base station continuously transmits the m second SIs may also be k × time-frequency repetition period, or the period in which the base station continuously transmits the m second SIs may also be an integer multiple of k × time-frequency repetition period. The time-frequency repetition period may be the length of one superframe, for example, in an 8X region, the time-frequency repetition period is 80 ms × 8 — 5.12 seconds.

optionally, the period T1 in which the base station continuously sends the m times of the first SI may be the k × time-frequency repetition period; the period T2 for the base station to continuously send the m second SIs may be k × time-frequency repetition period (same as T1), or may be an integer multiple of k × time-frequency repetition period (T2 is an integer multiple of T1). Specifically, if T1 and T2 are the same, the base station continuously transmits the first SI/second SI m times in each T1/T2; if T2 is an integer multiple of T1, the base station consecutively transmits m times the first SI in each T1, and consecutively transmits m times the second SI in each integer multiple of T1, i.e., T2.

For example, as shown in fig. 8, assuming that the first SI is SIB1 and the second SI is SIB2-SIB4, the base station continuously transmits SIB1 and SIB2-SIB4 for 8 times in the first transmission process; in the second transmission process, the base station transmits the data frame of the SIB4 to be null; in the third transmission process, the base station continuously transmits SIB1 and SIB2-SIB 48 times, i.e. the period T2 'of the base station transmitting SIB2-SIB3 is the same as the period T1 of the base station transmitting SIB1, and the period T2' of the base station transmitting SIB4 is 2 times the period T1 of the base station transmitting SIB 1.

As shown in fig. 9, on the basis of fig. 3, the SI transmission method provided in the embodiment of the present invention may further include:

s103, the base station maps the second SI to the first PDSCH, and maps Downlink Control Information (DCI) to the first PDSCH.

And S104, the base station continuously transmits m times of second SI on the first PDSCH according to the DCI instruction.

the execution sequence of S102 and S103 is not limited in the embodiment of the present invention, that is, the embodiment of the present invention may execute S102 first and then execute S103; s103 may be executed first, and then S102 may be executed; s102 and S103 may also be performed simultaneously.

in the embodiment of the present invention, as shown in fig. 10, when the base station sends the second SI to the UE, the second SI needs to be mapped to the first PDSCH from the BCCH through the BCH first, and the DCI needs to be mapped to the first PDSCH. The BCCH is a logical channel, BCH is a transport channel, and the first PDSCH is a physical channel.

specifically, in S104, the base station may transmit the second SI m times consecutively on the first PDSCH according to the DCI instruction, where the second SI is one of the following:

(c) the base station transmits the second SI m times consecutively in the DCI variable length portion in the DCI interval according to the DCI indication of the DCI fixed length portion in the DCI interval on the first PDSCH.

the DCI interval may include a DCI fixed length part, a DCI variable length part, and a DCI downlink burst part.

specifically, the base station indicates the DCI variable length portion in the DCI interval by carrying a System information-access network temporary identifier (SI-RNTI) in a UE identifier list field of the DCI fixed length portion in the DCI interval on the first PDSCH and carrying the DCI in the DCI fixed length portion. Specifically, if the base station needs to send a second SI to the UE, the base station may set the SI-RNTI in a first one of the UE identity list fields, and after detecting the SI-RNTI, the UE may receive the second SI from the DCI variable length portion in the DCI interval according to the DCI indication of the DCI fixed length portion in the DCI interval.

The DCI carried by the DCI fixed length part in the DCI interval on the first PDSCH may be the number of the DCI variable length part, and is used to indicate that there is a second SI transmission on the DCI variable length part of a certain number on the first PDSCH.

illustratively, as shown in fig. 11, the base station transmits m times of the second SI to the UE consecutively according to the DCI of the DCI fixed length part in the DCI interval on the first PDSCH.

In particular, in the embodiment of the present invention, for convenience of illustration, the DCI fixed length part may be expressed as DCI (fixed); the DCI variable length part may be denoted as DCI (variable); the DCI downlink burst part may be denoted as DCI (burst).

(d) And the base station continuously transmits the second SI m times in the DCI downlink burst part in the DCI interval according to the DCI instruction of the DCI fixed length part in the DCI interval on the first PDSCH.

the method for the base station to indicate the DCI downlink burst part in the DCI interval through the DCI of the DCI fixed length part in the DCI interval on the first PDSCH is similar to the method for the base station to indicate the DCI variable length part in the DCI interval through the DCI of the DCI fixed length part in the DCI interval in the first PDSCH, which may specifically refer to the related description in (c) above, and is not repeated here.

The DCI carried by the DCI fixed length part in the DCI interval on the first PDSCH may be a number of a DCI downlink burst part, and is used to indicate that there is a second SI transmission on the DCI downlink burst part with a certain number on the first PDSCH.

For example, as shown in fig. 12, the base station transmits m times of the second SI to the UE consecutively in the DCI downlink burst section in the DCI interval according to the DCI indication of the DCI fixed length part in the DCI interval on the first PDSCH.

(e) And the base station continuously transmits the second SI m times in the DCI downlink burst part in the DCI interval according to the DCI instruction of the DCI variable length part in the DCI interval on the first PDSCH.

The method for the base station to indicate the DCI downlink burst portion in the DCI interval through the DCI of the DCI variable length portion in the DCI interval on the first PDSCH is similar to the method for the base station to indicate the DCI downlink burst portion in the DCI interval through the DCI of the DCI fixed length portion in the DCI interval in the first PDSCH, which may specifically refer to the related description in (d) above, and is not repeated here.

the DCI carried by the DCI variable length part in the DCI interval on the first PDSCH may be a number of a DCI downlink burst part, and is used to indicate that there is a second SI transmission on the DCI downlink burst part with a certain number on the first PDSCH.

For example, as shown in fig. 13, the base station continuously transmits m times the second SI to the UE in the DCI downlink burst section in the DCI interval according to the DCI indication of the DCI variable length section in the DCI interval on the first PDSCH.

as shown in fig. 14, S103 to S104 in fig. 9 may be:

s103a, the base station maps the second SI to the first PDSCH and maps the DCI to the second PDSCH.

S104a, the base station transmits the second SI m times consecutively on the first PDSCH according to the DCI instruction.

The execution sequence of S102 and S103a is not limited in the embodiment of the present invention, that is, the embodiment of the present invention may execute S102 first and then execute S103 a; s103a may be executed first, and then S102 may be executed; s102 and S103a may also be performed simultaneously.

In the embodiment of the present invention, as shown in fig. 15, when the base station sends the second SI to the UE, the second SI needs to be mapped to the first PDSCH from the BCCH through the BCH first, and the DCI needs to be mapped to the second PDSCH. The BCCH is a logical channel, BCH is a transport channel, and the first PDSCH is a physical channel.

Specifically, in S104a, the base station may transmit the second SI on the first PDSCH m times in succession according to the DCI instruction, where the second SI is one of the following:

(f) And the base station continuously transmits the second SI m times in the DCI downlink burst part on the first PDSCH according to the DCI instruction of the DCI fixed length part in the DCI interval on the second PDSCH.

in this embodiment, since there is no DCI fixed length part and DCI variable length part on the first PDSCH and only a DCI downlink burst part, the base station needs to indicate the downlink burst part on the first PDSCH when sending the second SI on the DCI downlink burst part on the first PDSCH. The DCI interval on the second PDSCH may include a DCI fixed length part, a DCI variable length part, and a DCI downlink burst part.

The method for the base station to indicate the DCI downlink burst part on the first PDSCH through the DCI of the DCI fixed length part in the DCI interval on the second PDSCH is similar to the method for the base station to indicate the DCI downlink burst part in the DCI interval through the DCI of the DCI fixed length part in the DCI interval in the first PDSCH, which may specifically refer to the related description in (d) above, and is not repeated here.

the DCI carried by the DCI fixed length part in the DCI interval on the second PDSCH may be the number of the second PDSCH and the number of the DCI downlink burst part, and is used to indicate that there is a second SI transmission on the DCI downlink burst part of a certain number on the PDSCH of the certain number.

for example, as shown in fig. 16, the base station continuously transmits m times the second SI to the UE in the DCI downlink burst on the first PDSCH according to the DCI indication of the DCI fixed length part in the DCI interval on the second PDSCH.

(g) And the base station continuously transmits the second SI m times in the DCI downlink burst part on the first PDSCH according to the DCI indication of the DCI variable length part in the DCI interval on the second PDSCH.

The method for the base station to indicate the DCI downlink burst section on the first PDSCH through the DCI of the DCI variable length section in the DCI interval on the second PDSCH is similar to the method for the base station to indicate the DCI downlink burst section in the DCI interval through the DCI of the DCI variable length section in the DCI interval in the first PDSCH, which may specifically refer to the related description in (e) above, and is not repeated here.

the DCI carried by the DCI variable length part in the DCI interval on the second PDSCH may be the number of the first PDSCH and the number of the DCI downlink burst part, and is used to indicate that there is a second SI transmission on the DCI downlink burst part of a certain number on the first PDSCH of the certain number.

for example, as shown in fig. 17, the base station continuously transmits m times the second SI to the UE in the DCI downlink burst of the first PDSCH according to the DCI of the DCI variable length part in the DCI interval on the second PDSCH.

as shown in fig. 18, S103 to S104 in fig. 9 may be:

s103b, the base station maps the second SI to the first PDSCH.

S104b, the base station continuously sends m times of second SI on the preset superframe of the first PDSCH; the superframe number (SFN) of the preset superframe satisfies SFN mod (the period of continuously transmitting the m times of the second SI/DCI interval) is 0, where the period of continuously transmitting the m times of the second SI is an integer multiple of the DCI interval.

The execution sequence of S102 and S103b is not limited in the embodiment of the present invention, that is, the embodiment of the present invention may execute S102 first and then execute S103 b; s103b may be executed first, and then S102 may be executed; s102 and S103b may also be performed simultaneously.

In the embodiment of the present invention, as shown in fig. 19, when the base station sends the second SI to the UE, the second SI needs to be mapped to the first PDSCH from the BCCH via the BCH first. The BCCH is a logical channel, BCH is a transport channel, and the first PDSCH is a physical channel.

specifically, in S104b, the base station may continuously transmit the second SI m times to the UE on the DCI downlink burst portion in the preset superframe. The SFN of the preset superframe satisfies SFN mod (a period/DCI interval for continuously transmitting m times of the second SI) is 0, where the period for continuously transmitting m times of the second SI is an integer multiple of the DCI interval. Exemplarily, the DCI interval of the 8X region is 320 milliseconds.

illustratively, as shown in fig. 20, the base station repeatedly transmits the second SI m times to the UE on the DCI downlink burst portion of the preset super-frame in the first PDSCH.

in the SI transmission method provided in the embodiments of the present invention, the first SI is transmitted on the first PBCH, and the second SI is transmitted on the first PDSCH, so that the problem that if all the SI is transmitted on the first PBCH when the content of the SI is too much, the transmission period of the SI may be too long can be avoided, thereby shortening the time for the UE to receive the SI, and further saving the power consumption of the UE.

Optionally, the first PDSCH may be a PDSCH in a coverage area with the worst channel quality; but may also be all PDSCHs in all coverage areas, and the invention is not limited.

further, when the first PDSCH is the PDSCH in the coverage area with the worst channel quality, a gap (gap) may be configured for the UE in the connected state and needing to receive the SI based on the listening capability of the UE, so as to ensure that the base station does not schedule data on the PDSCH in the coverage area where the UE is located in the gap, but only enable the UE to listen to the PDSCH in the coverage area with the worst channel quality to receive the second SI. The listening capability of the UE may be understood as a bandwidth size that the UE can listen to simultaneously, that is, whether the UE can listen to the PDSCH in the coverage area where the UE is located and the PDSCH in the coverage area where the channel quality is the worst.

Further, as shown in fig. 21, when the first PDSCH is a PDSCH in all coverage areas, it needs to be ensured that, in the DCI interval on each PDSCH, the start points of superframes indicating that the DCI fixed length part of the DCI downlink burst part transmitting the second SI is the same, so that it can be ensured that the UE accurately knows the start point of the superframe transmitting the second SI on each PDSCH, thereby ensuring that the UE can correctly receive the second SI. At this time, the period in which the base station continuously transmits the second SI m times is a common multiple of DCI intervals on the PDSCH in all coverage areas. For example, in fig. 21, the starting point of the DCI1 fixed length part indicating the DCI1 downlink burst part on PDSCH1 (i.e., the superframe starting point) is the same as the starting point of the DCI1 fixed length part indicating the DCI1 downlink burst part on PDSCH 2; the starting point of the DCI8 fixed length part on PDSCH1 indicating the DCI8 downlink burst part is the same as the starting point of the DCI2 fixed length part on PDSCH2 indicating the DCI2 downlink burst part. Assuming that the DCI interval on PDSCH1 is 320 ms and the DCI interval on PDSCH2 is 640 ms, the period for the base station to continuously transmit the second SI m times is a common multiple of 320 ms and 640 ms, that is, 640 ms.

optionally, in order to further save power consumption of the UE, it is required to ensure that the UE can receive all SIs in a short time in the awake state, and therefore, as shown in fig. 22, a starting time point of the base station transmitting the second SI on the first PDSCH for the 1 st time may be set between an ending time point of the base station transmitting the first SI on the first PBCH for the 1 st time and an ending time point of the base station transmitting the first SI on the first PBCH for the mth time.

as shown in fig. 23, S103 to S104 in fig. 9 may be:

s103c, if n > k, the base station maps the second SI to the second PBCH.

S104c, the base station continuously transmits the second SI m times on the second PBCH.

the execution sequence of S102 and S103c is not limited in the embodiment of the present invention, that is, the embodiment of the present invention may execute S102 first and then execute S103 c; s103c may be executed first, and then S102 may be executed; s102 and S103c may also be performed simultaneously.

as shown in fig. 24, when the base station sends the second SI to the UE, the second SI needs to be mapped from the BCCH to the second PBCH through the BCH. The BCCH is a logical channel, BCH is a transport channel, and the second PBCH is a physical channel.

specifically, as shown in fig. 25, when the second SI is specifically n-k SIBs different from the first SI in the n SIBs, in S104c, that is, the base station continuously transmits the second SI m times on the second PBCH, specifically, the second SI may be:

s104c1, the base station sends n-k SIBs on m x (n-k) continuous data frames on the second PBCH.

Specifically, in S104c1, the method for the base station to send n-k SIBs on m × (n-k) consecutive data frames on the second PBCH may be one of the following:

(h) The base station continuously sends the p-th SIB in n-k SIBs from the m-th (p-1) +1 data frame to the m-th p data frame of m-x (n-k) continuous data frames on the second PBCH, wherein p is a positive integer and is less than or equal to n-k.

As shown in fig. 26, assuming that an 8X region is taken as an example, m is 8, one superframe includes 8 data frames, and the numbers of the 8 data frames are data frame No. 1, data frame No. 2, and data frame No. 8 in sequence. The base station continuously transmits the p-th SIB (i.e., SIBp) of n-k SIBs on the 8x (p-1) +1 data frames of the 8x (n-k) consecutive data frames on the second PBCH to the 8x p data frames.

specifically, after the base station continuously transmits the SIB m times, the SIB is continuously transmitted m times, and so on, when the base station continuously transmits n-k SIBs in sequence, that is, after the base station continuously transmits each SIB m times separately in sequence, the base station may start the process of transmitting the SIB n-k next according to the method (h). That is, the base station may periodically transmit n-k SIBs in the method of (h) above.

the method (h) above may facilitate the extension of the second SI, that is, when the second SI needs to be extended, the information extended in the second SI may be directly and repeatedly sent on the second PBCH, and may not affect the transmission of the original information in the second SI.

(i) the base station transmits the p-th SIB in n-k SIBs on the p + k x (q-1) data frames of m x (n-k) continuous data frames, wherein p is a positive integer, q is a positive integer, p is less than or equal to k, and q is less than or equal to m.

as shown in fig. 27, assuming that an 8X system is taken as an example, m is 8, and one superframe includes 8 data frames, and the numbers of the 8 data frames are data frame No. 1, data frame No. 2, and data frame No. 8 in sequence. The base station transmits the p-th SIB (i.e., SIBp) of the n-k SIBs on the p + k × (q-1) data frames of the 8 × (n-k) consecutive data frames.

Specifically, after the base station sends 1 SIB for the first time, the base station continuously sends 1 SIB for the next time, and so on, after the base station continuously sends n-k SIBs for 1 time, the base station continuously sends n-k SIBs for the next time, and the base station repeatedly sends n-k SIBs for m times, that is, after the base station continuously sends n-k SIBs together for m times, the base station may start the process of sending n-k SIBs next time according to the method in (i). That is, the base station periodically transmits n-k SIBs according to the method of (i) above.

in the method (i), for the UE with better received signal quality, if the UE correctly receives the second SI sent by the base station for at least 1 time, the UE may not continue to monitor the second PBCH to receive the second SI, so that power consumption of the UE may be saved.

in the SI transmission method provided in the embodiments of the present invention, the first SI is transmitted on the first PBCH, and the second SI is transmitted on the second PBCH, so that a problem that if all the SI are transmitted on one PBCH when the content of the SI is too much, the transmission period of the SI may be too long can be avoided, and thus the time for the UE to receive the SI is shortened, and the power consumption of the UE is saved.

It can be understood by those skilled in the art that the base station transmits the first SI/second SI m times consecutively, and the above embodiments and the corresponding drawings are only exemplary illustrations of the base station transmitting the first SI/second SI m times consecutively. The other processes for continuously sending the first SI/second SI m times are similar to the above one process for continuously sending the first SI/second SI m times, and are not described again.

alternatively, when the SI (including the first SI or the first SI and the second SI) is updated, the base station may notify the UE to update the SI. Specifically, the method for the base station to notify the UE to update the SI may be one of the following:

(1) And the base station sends a paging message to the UE in the change period, and sends the changed SI to the UE after the change period, wherein the paging message is used for indicating the UE to update the SI.

after the UE receives the paging message, the UE learns that the SI is changed according to the paging message and updates the SI after a change period.

Since the change of SI occurs only on a specific superframe, the concept of the change period described above is introduced. System information having the same content may be transmitted multiple times during a change period, which may be defined by its schedule. The boundary of the variation period is determined by the SFN, where the SFN satisfies SFN mod variation period of 0. The variation period may be configured in the SI. When the base station updates the SI (or part of the SI), the base station first notifies the UE of the update, and may specifically notify the UE in the whole change period, and in the next change period, the base station transmits the updated SI. When the UE receives the notification for the update, the UE starts to acquire the updated SI from the next change period. The UE starts to use the updated SI until the UE next acquires a new SI.

(2) And the base station carries an SI change label in the first PBCH, wherein the SI change label is used for indicating the UE to update the SI.

When the base station updates the SI, the base station may change the value of the SI change flag, for example, the base station may add 1 to the original value of the SI change flag. After the UE acquires the SI change tag carried in the first PBCH, the UE may determine whether the SI is updated by comparing the value of the SI change tag with the value of the SI change tag stored in the UE. For example, if the value of the SI change flag is different from the value of the SI change flag stored in the UE, the UE determines SI update, and the UE can update the SI.

Optionally, when the base station carries the SI change tag in the first PBCH, the base station may carry the SI change tag in the SI and send the SI change tag to the UE; or add a new data block in the first PBCH, and send the SI change tag to the UE by carrying it in the new data block, which is not limited in the present invention.

Optionally, when the base station carries the SI change tag in the first PBCH, the base station may also carry indication information in the first PBCH, where the indication information may be used to indicate that a specific SI or some SIs are updated, that is, the UE may only update the updated SI or some SIs according to the indication information.

The method for updating the SI provided by the embodiment of the invention can ensure that the UE can timely and accurately receive the updated SI after the base station updates the SI, and can timely use the updated SI for communication.

The embodiment of the invention provides a transmission method of SI, a base station maps a first SI to a first PBCH; and continuously transmitting the first SI m times on the first PBCH, wherein m is an integer larger than 1. In the embodiment of the invention, the base station can repeatedly send the first SI by continuously sending the first SI on the first PBCH, so that the UE positioned in a place with poor network coverage in an M2M system can be ensured to correctly receive the first SI sent by the base station.
