Description

Method and device for notifying master information block MIB information

Technical Field

The invention relates to the field of communication, in particular to a method and a device for notifying Master Information Block (MIB) information.

Background

In the bi-Directional Connection (DC) issue discussed in R12, a terminal establishes a Connection with multiple stations, and accordingly, the terminal receives Master Information Block (MIB) Information transmitted by each station from a Physical Broadcast Channel (PBCH) Channel transmitted by the multiple stations, by decoding the MIB information of each site, the downlink System bandwidth, Physical Hybrid ARQ Indicator Channel (PHICH for short) configuration and System Frame Number (SFN) information of each site are known, the SFN information of each station is very important, and may affect the Radio Resource Management (RRM) measurement, Semi-Persistent Scheduling (SPS) Scheduling, Radio Link Failure (RLF) and other processing processes of the terminal.

In the conventional mode, the PBCH channel is used to send MIB information of a station, where the MIB information only includes the most basic system information, and specifically includes: downlink system bandwidth, PHICH configuration and SFN serial numbers. The MIB information is sent on the first 4 symbols of the 2 nd slot of the subframe 0 of each wireless frame in a period of 40ms, the transmission is repeated for 4 times in one period, and each time of transmission carries the same coded bit, so that the MIB information sent each time can be decoded independently, the terminal can successfully acquire the MIB information as long as the terminal can receive and decode one of 40ms under the condition that the channel quality is good enough, and if the channel quality is poor, a plurality of MIBs sent by 40ms can be combined in a soft mode and then decoded, so that the reliability of reading the MIB information by the terminal is greatly guaranteed.

An Assisted authorized Access (LAA) issue is introduced in R13, an LTE site uses an unlicensed frequency band in addition to a conventional Licensed frequency band, and according to the regulatory requirements of most countries and regions on the unlicensed frequency band, Before transmission is performed on the unlicensed frequency band, listening Before speaking, that is, following a Listen Before Talk (LBT) mechanism, how to send MIB information with a high requirement on reliability on an unlicensed carrier is a problem to be solved.

According to the conclusion of the current stage R13WI, PBCH is not transmitted in the unlicensed band, which is not problematic in a Carrier Aggregation (CA) mode in which the licensed band and the unlicensed band are aggregated, because PBCH may be transmitted through a licensed Carrier, but in a DC mode in which the unlicensed Carrier is used, if the licensed Carrier and the unlicensed Carrier are not co-located, it is impossible to notify User Equipment (User Equipment, UE) of MIB information of a site in which the unlicensed Carrier is used.

In order to solve the problem that the UE cannot be notified of MIB information of a station using an unlicensed carrier in the related art, no effective solution has been proposed at present.

Detailed Description

The invention will be described in detail hereinafter with reference to the accompanying drawings in conjunction with embodiments. It should be noted that the embodiments and features of the embodiments in the present application may be combined with each other without conflict.

It should be noted that the terms "first," "second," and the like in the description and claims of the present invention and in the drawings described above are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order.

The authorized carriers and the unlicensed carriers mentioned in the embodiments of the present invention are aggregated not in the CA mode, but in the non-CA mode, for example, in the DC mode, that is, the authorized carriers and the unlicensed carriers are located in different physical sites, and the interconnection and the interworking between the physical sites are realized through the non-ideal Backhaul, for example, an X2 interface.

Considering the unreliability of the unlicensed carrier, for the MIB information with fixed time-frequency transmission requirements, the licensed carrier undertakes the transmission of the MIB information of the unlicensed carrier, i.e. the licensed carrier not only needs to transmit its own MIB information, but also transmits the MIB information of the unlicensed carrier.

In this embodiment, a method for notifying master information block MIB information is provided, and fig. 1 is a flowchart of a first method for notifying master information block MIB information according to an embodiment of the present invention, where as shown in fig. 1, the flowchart includes the following steps:

step S102, a first site using an authorized carrier wave determines MIB information of a second site using an unauthorized carrier wave at a first moment;

step S104, the first site determines MIB information of the second site at the second moment according to the MIB information of the second site at the first moment;

step S106, the first site notifies the MIB information of the second site at the second time to the user equipment UE at the second time by using the authorized carrier.

The first time may be a time when the first station receives MIB information sent by the second station. Through the steps, the first site using the authorized carrier can determine the MIB information of the second site using the unauthorized carrier, so that the first site can inform the UE of the MIB information of the second site through the authorized carrier, and the UE can be ensured to receive the correct MIB information of the site using the unauthorized carrier by sending the MIB information to the UE through the authorized carrier. The problem that the MIB information of the sites using the unauthorized carrier waves cannot be notified to the UE in the related technology is solved, the MIB information of the sites using the unauthorized carrier waves is transmitted by using the authorized carrier waves, and the effect that the UE reliably receives the MIB information is improved.

The MIB information may include at least one of SFN information, downlink system bandwidth indication information, and PHICH resource configuration indication information. In an optional embodiment, when the MIB information includes system frame number SFN information, the determining, by the first station using the licensed carrier, MIB information of the second station using the unlicensed carrier at the first time includes: when the first corresponding relationship between the SFN information of the first station and the time point is different from the second corresponding relationship between the SFN information of the second station and the time point, the first station may receive SFN information from the second station at a third time through an interface between the first station and the second station, where the third time is a time when the second station sends the SFN information to the first station; determining SFN information of the second site at the first moment according to the SFN information of the second site at the third moment; and when the first corresponding relation between the SFN information of the first station and the time point and the second corresponding relation between the SFN information of the second station and the time point are the same, the first station determines the SFN information of the second station at the first moment according to the SFN information of the first station at the first moment. When the first corresponding relationship between the SFN information of the first station and the time point is different from the second corresponding relationship between the SFN information of the second station and the time point, the first station may determine the corresponding relationship between the SFN information of the second station and the time point according to the received SFN information of the second station from the second station at the third time and the corresponding timestamp (i.e., the third time), so as to determine the SFN information of the second station at the first time according to the corresponding relationship and the time of the first time. The following is a detailed description:

the determining, by the first station, the SFN information of the second station at the first time according to the SFN information of the second station at the third time includes: the first station determines time information of a third moment; when the first station and the second station maintain the same system clock, the first station may determine a first time difference according to the time information of the third time and the time information of the first time; the first station determines SFN information of the second station at the first moment according to the first time difference and the SFN information of the second station at the third moment; and/or when the first station and the second station maintain different system clocks, the first station may determine the SFN information of the second station at the first time according to the time information of the third time, the time information of the first time of the first station, the SFN information of the second station at the third time, and a predetermined interface delay between the first station and the second station. The following description will be made by taking an example in which the first station and the second station maintain the same system clock: assuming that a first station using a licensed carrier (in the following description, the licensed carrier may also refer to a first station using a licensed carrier) and a second station using an unlicensed carrier (in the following description, the unlicensed carrier may also refer to a second station using an unlicensed carrier) maintain the same system clock, the unlicensed carrier sends timestamp information to the licensed carrier at time T0 (corresponding to the third time mentioned above) through an interface (for example, an X2 interface), and the piece of information may include the following: a system clock T0 at the information transmission time, an SFN number SFN0 at the information transmission time, and a SubFrame number SF0 at the information transmission time. The licensed carrier receives the time stamp information from the unlicensed carrier at time T1. The authorized carrier estimates the SFN ordinal SFN1 of the unlicensed carrier at the current time T1 (corresponding to the first time mentioned above) according to the time difference (T1-T0). And according to the range of the SFN serial number, the authorized carrier maintains the SFN information of the unauthorized carrier. When the authorized carrier broadcasts the MIB information to the terminal through the PBCH, the SFN information of the unauthorized carrier is carried at the same time.

In another optional embodiment, the determining, by the first station, the SFN information of the second station at the first time according to the SFN information of the first station at the first time includes: when a first site and a second site maintain the same system clock, the first site determines that SFN information of the first site at the first moment is SFN information of the second site at the first moment; and/or when the first site and the second site maintain different system clocks, the first site determines the time information of the third moment sent by the second site; the first station determines a synchronization time difference according to the time information of the third moment, the time information of the first moment and the predetermined interface time delays of the first station and the second station; and the first station determines the SFN information of the second station at the first moment according to the synchronization time difference and the SFN information of the first station at the first moment. The following distance description is made for the case when the first station and the second station maintain different system clocks: in this embodiment, the authorized carrier may know the time delay Δ t of the interface between itself and the unauthorized carrier by some technical means, and a synchronization control process needs to be performed between the authorized carrier and the unauthorized carrier, which may specifically be: and the unauthorized carrier sends synchronous control information to the authorized carrier through an interface at the time T0, and carries the current time stamp T0. The authorized carrier receives the synchronization control information from the unauthorized carrier at the time T1, and reads the unauthorized carrier time stamp information T0 carried in the synchronization control information. And the authorized carrier calculates the synchronization time difference delta T0 between the authorized carrier and the unauthorized carrier according to (T1-T0-delta T), calculates the SFN serial number and the SubFrame serial number of the unauthorized carrier according to the synchronization time difference and the SFN serial number and the SubFrame serial number of the authorized carrier, and maintains the SFN serial number of the unauthorized carrier according to the SFN serial number range. When the non-authorized carrier broadcasts the MIB information to the terminal through the PBCH, the SFN information of the non-authorized carrier is carried at the same time.

As can be seen from the foregoing embodiments, determining MIB information of the second station mainly includes the following two methods:

one method is that an unlicensed carrier (referring to a second station using an unlicensed carrier) forwards SFN information of itself (i.e., the second station) to an licensed carrier (referring to a first station using an licensed carrier) through an X2 interface, and after a certain time delay, the licensed carrier receives the SFN information of the unlicensed carrier, but the information is outdated, and the licensed carrier needs to adjust the information, so as to obtain and maintain "correct" MIB information of the unlicensed carrier. Here, "correct" means the same MIB information maintained by itself on the unlicensed carrier. Referring to fig. 2 in particular, fig. 2 is a schematic diagram of forwarding SFN information from an unlicensed carrier to a licensed carrier according to an embodiment of the present invention.

In another method, the unlicensed carrier does not directly forward own SFN information to the licensed carrier through an X2 interface, but the unlicensed carrier and the licensed carrier need to initiate a series of "synchronous control" processes through an X2 interface, and through the "synchronous control" processes, the licensed carrier can calculate SFN information of the unlicensed carrier according to the own SFN information and maintain the SFN information. Specifically, referring to fig. 3, fig. 3 is a schematic diagram of a process of initiating a synchronization control from an unlicensed carrier to a licensed carrier according to an embodiment of the present invention.

In an optional embodiment, when the MIB information includes a downlink system bandwidth indication and/or a physical hybrid automatic repeat indicator channel PHICH resource configuration indication, determining, by a first station using a licensed carrier, MIB information of a first time of a second station using an unlicensed carrier includes: the first site receives downlink system bandwidth indication and/or PHICH resource configuration indication information of a third moment from the second site through an interface between the first site and the second site, wherein the third moment is a moment when the second site sends the downlink system bandwidth indication and/or the PHICH resource configuration indication information; and determining the downlink system bandwidth indication and/or PHICH resource configuration indication information of the second site at the first moment according to the downlink system bandwidth indication and/or PHICH resource configuration indication information of the second site at the third moment. The interface may be an X2 interface.

In an optional embodiment, the notifying, by the first station, the MIB information of the second station at the second time to the UE at the second time by using the licensed carrier includes: the first site carries the MIB information of the second site at the second moment in the MIB information of the first site at the second moment, and sends the MIB information of the first site at the second moment to the UE through an authorized carrier; or, the first site carries MIB information of the second site at the second time in a system information block SIB, and sends the SIB to the UE through the authorized carrier. The MIB information may include at least one of SFN information, downlink system bandwidth indication information, and PHICH resource allocation indication information. In this embodiment, the transmission subframe configuration of the MIB information of the first station may be different from the transmission subframe configuration of the SIB, for example, the MIB may be transmitted at subframe #0 of each radio frame, and the SIB1 is transmitted at subframe #5 of every other radio frame (i.e., odd radio frame or even radio frame). Therefore, the value of the second time may be multiple, and the values of the second time corresponding to the transmission modes of the MIB information of different second sites may be different, and the specific value is determined according to the specific application.

In an optional embodiment, the MIB information of the first site at the second time of the first site, which carries the MIB information of the second site at the second time, includes: the first site carries the second-time MIB information of the second site by using a reserved field in the second-time MIB information of the first site, where the second-time MIB information of the second site includes second-time SFN information or downlink system bandwidth indication of the second site. For example, a field of systemFrameNumber _ uc is added in the MIB, and the field may be used to indicate SFN information of a certain second station, where the length of the field is the same as that of the systemFrameNumber and is 8bits, and in order to ensure that the MIB length has backward compatibility, the total bit length of the MIB information is not changed, specifically, see fig. 4, where fig. 4 is a schematic diagram of an MIB structure of an authorized carrier bearing SFN information of an unlicensed carrier according to an embodiment of the present invention.

In an alternative embodiment, the reserved field supports a function to be read by a terminal of a predetermined class. In this embodiment, a terminal that may define a Category or capabilities above a Category needs to read the systemFrameNumber _ uc field in the MIB. The type of the terminal may also be configured in advance, for example, by higher layer signaling.

In an optional embodiment, the carrying, by the first station, the SFN information of the second site at the second time using the reserved field in the MIB information of the first site at the second time includes: the first site utilizes the 8bit in the reserved field to carry the high 8bit information of the SFN information of the second site at the second moment, and utilizes the 2bit except the 8bit in the reserved field to represent the low 2bit information of the SFN information of the second site at the second moment. In this embodiment, after the field of systemFrameNumber _ uc is added, it is to be ensured that the UE has backward compatibility with the decoding mode of the MIB, that is, the lower 2 bits in the 10bitmap corresponding to the SFN are still used to determine the PBCH scrambling code, and whether the lower 2 bits of the SFN sequence numbers of the authorized carrier and the unauthorized carrier are the same or not, the PBCH scrambling code is mapped by using the lower 2 bits of the SFN sequence number of the authorized carrier, so that the terminal can read out the 10-bit SFN sequence number of the authorized carrier and the higher 8-bit SFN sequence number of the unauthorized carrier through blind detection, and for the lower 2 bits of the SFN sequence number, the reserved bits in the MIB can be used to represent.

In an optional embodiment, the first station may use 2 bits except for 8bits in the reserved field to represent the low 2-bit information of the SFN information of the second station at the second time point by the following manner: and using 2 bits except the 8bits in the reserved field to represent a difference value of the low 2-bit information of the SFN information of the first site at the second moment and the low 2-bit information of the SFN information of the second site at the second moment, wherein the difference value is used for determining the low 2-bit information of the SFN information of the second site at the second moment by the UE according to the difference value and the low 2-bit information of the SFN information of the first site at the second moment. The terminal can obtain the low 2 bits of the serial number of the authorized carrier SFN by means of blind detection, and then superimpose the difference value, so that the low 2 bits of the serial number of the unauthorized carrier SFN can be obtained, and the terminal can obtain the complete value of the serial number of the unauthorized carrier SFN. By means of the difference, the MIB information sent for 4 times in the 40ms period can be combined.

In an optional embodiment, the step of carrying, by the first station, the downlink system bandwidth indication at the second time of the second station in a reserved field in the MIB information at the second time of the first station includes: the first station utilizes the reserved field to carry downlink system bandwidth indication of one or more second stations, wherein the reserved field also carries first identification information, and the first identification information is used for identifying the corresponding relation between the downlink system bandwidth and the second stations. For example, the reserved field is divided into two 5 bits, wherein 3 bits of one 5bit carry a downlink system bandwidth indication of the second station, and 2 bits carry information for identifying the corresponding second station; and 3 bits of the other 5 bits carry downlink system bandwidth indication of the other second station, and 2 bits carry information for identifying the other second station.

In an optional embodiment, the reserved field is a spare field.

In an optional embodiment, the carrying, by the first station, MIB information of the second station at the second time in a system information block SIB includes: the first station carries the MIB information of the second station at the second time by using the information entry IE newly added in the SIB, where the MIB information of the second station at the second time includes at least one of the following information of the second station at the second time: SFN information, downlink system bandwidth indication and physical hybrid automatic repeat indicator channel PHICH resource configuration indication.

In an optional embodiment, the MIB information (which may include at least one of SFN information, downlink system bandwidth indication information, and PHICH resource configuration indication information) includes MIB information of one or more second sites, that is, an IE entry is added to SIB1 or SIBx of a licensed carrier to carry an SFN sequence number of an unlicensed carrier. In this embodiment, the SIB further carries second identification information, where the second identification information is used to identify a correspondence between the second site and the MIB information at the second time carried in the SIB. The IE entry is an optional entry that may not be carried if the terminal is not configured with an available unlicensed carrier.

As can be seen from the foregoing embodiments, in consideration of the importance of the MIB information, the transmission rule should follow the characteristics of periodicity, repeatability, mergeability, fixed time-frequency resource transmission, and the like, so two methods for transmitting the MIB information of the unlicensed carrier to the UE are provided in the embodiments of the present invention, and the method for transmitting the MIB information of the second site to the UE mainly includes the following two methods:

one method is that the authorized carrier sends its own MIB information and the MIB information of the unauthorized carrier simultaneously in the PBCH. The specific method is that the authorized carrier sends MIB information according to the PBCH sending configuration of the authorized carrier, and the reserved field is utilized to carry the MIB information of the unauthorized carrier in the MIB information. By adopting the mode, the characteristic of MIB transmission needs to be combined, the SFN information is transmitted in the MIB in a bit string mode, the range of the SFN serial number is 0-1023, and 10-bit information indication is needed, but in the MIB, the display information indication of the SFN serial number is only 8bits, the higher 8bits of the SFN serial number bit string correspond to, and the lower 2 bits of the SFN serial number bit string adopt an implicit mode indication, namely indication is carried out through different PBCH scrambling codes. Then, when the PBCH of the authorized carrier simultaneously carries the SFN information of the authorized carrier and the SFN information of the unauthorized carrier, the high 8bits of the two SFN information are both sent in an explicit bit string manner, and to ensure backward compatibility, for the low 2 bits of the SFN information of the authorized carrier, the scrambling code is used for implicit indication, and the selection of the scrambling code should correspond to the low 2 bits of the low SFN information of the authorized carrier, so that for the low 2bit information of the unauthorized carrier, but the low 2bit information of the SFN information of the authorized carrier and the SFN information of the unauthorized carrier are probably not consistent, so that an extra 2 bits is also needed to indicate the offset of the low 2 bits of the two SFNs. In this way, in summary, the SFN indication for the unlicensed carrier is actually a mode of adding an implicit scrambling code to the 10-bit explicit information. By the method, reliable transmission of the non-authorized carrier SFN information is ensured, and the characteristic that the repeated information can be combined is not influenced.

Another method is that the authorized carrier sends MIB information of the unlicensed carrier in the PDSCH. Specifically, the information may be carried in SIB1 or SIBx, where x may be any one of 2 to 18, and an IE indicating the information of the unlicensed carrier SFN is added to SIB1 or SIBx, and the specific length may be 10 bits.

Fig. 5 is a flowchart of a method for notifying master information block MIB information according to a second embodiment of the present invention, and as shown in fig. 5, the flowchart includes the following steps:

step S502, using a second site of an unauthorized carrier to determine MIB information of the second site at a third moment;

step S504, the second station sends, at the third time, the MIB information at the third time of the second station to the first station using the authorized carrier, where the MIB information at the third time of the second station is used for the first station to notify, at the second time, the MIB information at the second time of the second station to the user equipment UE by using the authorized carrier.

Through the steps, the second site using the unauthorized carrier can inform the UE of the MIB information of the second site by using the first site using the authorized carrier, so that the MIB information of the second site is sent to the UE by using the authorized carrier, and the UE is ensured to receive the correct MIB information of the site using the unauthorized carrier. The problem that the MIB information of the sites using the unauthorized carrier waves cannot be notified to the UE in the related technology is solved, the MIB information of the sites using the unauthorized carrier waves is transmitted by using the authorized carrier waves, and the effect that the UE reliably receives the MIB information is improved.

In an optional embodiment, the method further includes the second station sending time information of a third time to the first station. The time information at the third time can enable the first site to determine the MIB information of the second site at any time, thereby ensuring that the first site can maintain accurate MIB information of the second site, and ensuring that the UE receives accurate MIB information of the second site.

The invention is illustrated below with reference to specific examples:

example 1:

for a terminal UE (same as the user equipment UE), the system is configured with a Macro base station Macro eNB and a Small cell to provide a dual-link service for the terminal, wherein the Macro eNB adopts an authorized carrier f1, the Small cell adopts a non-carrier f2, and the Macro eNB working on f1 is connected with the Small cell working on f2 through an X2 interface. Precise synchronization between Macro enbs and Small cells is not achieved, but they maintain the same system clock, such as via GPRS positioning satellites.

The method comprises the following steps that a Small cell initiates a synchronous control process to a Macro eNB, and specifically comprises the following steps: the method comprises the steps that a Small cell sends a 'synchronization request' signaling to a Macro eNB at a time T0, the signaling carries real-time information when the Small cell sends the signaling, namely a time stamp T0, after the signaling is transmitted through an X2 port, the Macro eNB receives the signaling at the time T1, the Macro eNB reads the time stamp T0 in the signaling, knows that the Small cell sends the signaling at the time T0, and knows that the X2 interface delay between the Small cell and the Macro eNB is delta T _ X2, so that the Macro eNB can calculate the synchronization time difference delta T between the Small cell and the Small cell: and delta T is T1-T0-delta T _ x 2.

Through the process of 'synchronous control', the Macro eNB knows the synchronous time difference delta t between the Macro eNB and the Small cell, and can calculate the radio frame number SFN0_ uc and the subframe number SF0_ uc of the Small cell according to the SFN0 and the subframe number SF0 of the Macro eNB, and the specific method is as follows:

the Macro eNB maintains a radio frame number SFN _ uc of the Small cell, when the PBCH sending time of the Macro eNB is reached, namely a subframe 0 of each radio frame, the Macro eNB sends an SFN sequence number SFN1 of the Macro eNB and the SFN sequence number SFN1_ uc of the Small cell in an MIB message at the same time, and the specific signaling construction method comprises the following steps:

wherein:

the dl-Bandwidth field is the downlink system Bandwidth of a carrier f1 corresponding to the Macro eNB;

the dl-Bandwidth field is PHICH channel resource allocation of a carrier f1 corresponding to the Macro eNB;

the systemFrameNumber field is the upper 8bits of the bit string corresponding to the current SFN serial number of the carrier f1 corresponding to the Macro eNB;

the field of the systemFrameNumber _ uc is the high 8bits of the bit string corresponding to the current SFN serial number of the carrier f2 corresponding to the Small cell;

the systemFrameNumber _ offset field is an offset of the lower 2 bits of the bit string corresponding to the systemFrameNumber _ uc from the lower 2 bits of the bit string corresponding to the systemFrameNumber.

After receiving such a MIB message from the Macro eNB, the terminal UE performs blind detection with all the candidate 4 types of scrambling codes, and finally determines the scrambling code of the MIB message, thereby obtaining the low 2-bit information of the corresponding bit string of the corresponding systemFrameNumber, and by decoding and reading the 8-bit information of the corresponding systemFrameNumber field, can obtain the complete current SFN serial number SFN1(10bit) of the Macro eNB. And superposing the low 2-bit information of the bit string corresponding to the system FrameNumber and the system FrameNumber _ offset information to obtain the low 2-bit information corresponding to the current SFN1_ uc of the Small cell, and then decoding and reading the 8-bit information corresponding to the field of the system FrameNumber _ uc to obtain the complete current SFN1_ uc (10 bits) of the Small cell.

Example 2:

for a terminal UE (namely, user equipment UE), the system is configured with a Macro base station Macro eNB and a Small cell to provide a dual-link service for the terminal, wherein the Macro eNB adopts an authorized carrier f1, the Small cell adopts a non-carrier f2, and the Macro eNB working on f1 and the Small cell working on f2 are connected through an X2 interface. Precise synchronization between Macro enbs and Small cells is not achieved, but they maintain the same system clock, such as via GPRS positioning satellites.

The Small cell sends the SFN serial number and the timestamp information of the Small cell to the Macro eNB, and the method specifically comprises the following steps: the method comprises the steps that Small cells send SFN notification signaling to Macro eNB at time T0, wherein the SFN notification signaling comprises a current SFN serial number SFN0, a current subframe number SF0 and a time stamp T0 of the current time, after the signaling is transmitted through an X2 port, the Macro eNB receives the signaling at time T1, the Macro eNB reads the time stamp T0 in the signaling, knows that the Small cells send the signaling at time T0, and knows that the SFN serial number of the Small cells at time T0 is SFN0 and the subframe number is SF 0.

According to the time difference Δ T between the time T0 and the time T1, Δ T is T1-T0, so that the subframe number of the Small cell at the current time T1 can be calculated as follows:

the radio frame number should be:

then, the Macro eNB maintains the radio frame number SFN _ uc of the Small cell, and sends the MIB information carrying the radio frame number of the Small cell in the subframe where the MIB information is sent, which is the same as embodiment 1.

Example 3:

after obtaining the SFN information of the Small cell according to the method in embodiment 1 or embodiment 2, the Macro eNB loads the SFN information of the Small cell in the SIB1 sent by the PDSCH, specifically, in the SIB1, an IE item, namely an SFN notification item of the Small cell is added, where the length of the IE item is 8bits, and corresponds to the high 8bits of the bit string corresponding to the current SFN sequence number of the Small cell, and the low 2 bits of the bit string corresponding to the current SFN sequence number of the Small cell are sent in an implicit manner, and similar to the sending method of the MIB, the low 2 bits are also corresponding to the scrambling code.

After receiving SIB1 information carrying Small cell SFN serial number sent by Macro eNB, the terminal determines the corresponding scrambling code by blind detection, thereby determining the low 2bit of the bit string corresponding to the current SFN serial number of the Small cell, then decodes the SIB1 information, reads the IE item with the high 8bit of the bit string corresponding to the current SFN serial number of the Small cell, and finally obtains the complete 10bit information corresponding to the current SFN serial number of the Small cell after combination.
