A terminal device may be called an access terminal, subscriber unit, subscriber station, mobile, remote station, remote terminal, mobile device, user terminal, wireless network device, user agent, or user equipment. The terminal may be a cellular phone, a cordless phone, a Session Initiation Protocol (SIP) phone, a Wireless Local Loop (WLL) station, a Personal Digital Assistant (PDA), a handheld device with wireless communication capability, a computing device or other device connected to a wireless modem, a vehicle-mounted device, a wearable device or internet of things, a terminal device in a vehicle network, a terminal device in a future network in any form, and so on.

Network device 120 may be a Radio Access Network (RAN) device. One example of a RAN device is a Base Station (BS).

It should be understood that the specific type of base station is not limited herein. In systems using different radio access technologies, the names of devices with base station functionality may vary. For convenience of description, in all embodiments of the present application, the above-mentioned apparatuses providing a terminal with a wireless communication function are collectively referred to as a base station.

In the communication system shown in fig. 1, network device 120 may send information to one or more of terminal devices 101 through 106.

The first indication information is used for indicating that the SIB1 is transmitted on the non-anchor carrier, the second indication information is used for indicating that the number of repetitions of the SIB1 is 8, and in case that the network device sends the third indication information, the subframe position of the SIB1 on the non-anchor carrier may be preset.

For example, in the case that the first indication information is used to indicate that the SIB1 is transmitted on the non-anchor carrier, the second indication information is used to indicate that the number of repetitions of the SIB1 is 8, and the network device sends the third indication information, the subframe position of the SIB1 preset on the non-anchor carrier may be subframe 0.

The first indication information is used to indicate that SIB1 is transmitted on the non-anchor carrier, the second indication information is used to indicate that the number of repetitions of SIB1 is 16, and in a case where the network device sends the third indication information, the second indication information may be used to indicate that a subframe position of SIB1 on the non-anchor carrier is subframe p, or subframe p and subframe q, where p and q are integers greater than or equal to 0 and less than 10.

The subframe p and the subframe q may be subframes in the same radio frame.

A schematic flow chart of a method of transmitting the SIB1 of one embodiment of the present application is shown in figure 3. The method shown in fig. 3 may include S310, S320, S330, and S340.

S310, the terminal equipment receives the first indication information and the second indication information.

The terminal device may receive the first indication information and the second indication information in the MIB. The first indication information and the second indication information can be transmitted in the same MIB.

The first indication information may be 1bit, for example, the first indication information may be "0" or "1".

The second indication information may be T bits. For example, the second indication information may be "1000", "0001", or "1100", etc.

Optionally, the value of the second indication information may be consistent with the scheduling information (schedulinglnfossib 1) of the SIB 1.

S320, the terminal equipment receives SIB1 according to the first indication information and the second indication information. Wherein, the terminal device receiving the SIB1 according to the first indication information and the second indication information includes: the terminal equipment determines that the SIB1 is transmitted on the anchor carrier or the non-anchor carrier according to the first indication information; when the terminal equipment determines that SIB1 is transmitted on the anchor carrier according to the first indication information, the terminal equipment determines the subframe position of SIB1 on the anchor carrier, determines the number of times of SIB1 repetition and the size of SIB1 transmission block according to the second indication information, and receives SIB1 on the anchor carrier according to the number of times of SIB1 repetition, the size of SIB1 transmission block and the subframe position of SIB1 on the anchor carrier; when the terminal equipment determines that the SIB1 is transmitted on the non-anchor carrier according to the first indication information, the terminal equipment determines the frequency domain position of the non-anchor carrier and the subframe position of the SIB1 on the non-anchor carrier, determines the number of times of repetition of the SIB1 and the size of the transmission block of the SIB1 according to the second indication information, and receives the SIB1 on the non-anchor carrier according to the number of times of repetition of the SIB1, the size of the transmission block of the SIB1, the frequency domain position of the non-anchor carrier, and the subframe position of the SIB1 on the non-anchor carrier, wherein at least one of the frequency domain position of the non-anchor carrier and the subframe position of the SIB1 on the non-anchor carrier is determined according.

The following first describes how the terminal device determines whether SIB1 is transmitted on the anchor carrier or the non-anchor carrier according to the first indication information.

When the terminal device determines that the SIB1 is transmitted on the anchor carrier or the non-anchor carrier according to the first indication information, one possible implementation manner is: and the terminal equipment determines whether the SIB1 is transmitted on the anchor carrier or the non-anchor carrier according to the first indication information and the preset corresponding relation between the '0' and the '1' and the anchor carrier or the non-anchor carrier.

For example, when the first indication information is "0", it may be determined that the SIB1 is transmitted on the anchor carrier; when the first indication information is "1," it may be determined that the SIB1 is transmitted on the non-anchor carrier.

Alternatively, when the first indication information is "1", it may be determined that the SIB1 is transmitted on the anchor carrier; when the first indication information is "0," it may be determined that the SIB1 is transmitted on the non-anchor carrier.

When the receiving terminal device determines that the SIB1 is transmitted on the anchor carrier according to the first indication information, how the terminal device determines the subframe position of the SIB1 on the anchor carrier, and how the number of repetitions of the SIB1 and the transport block size of the SIB1 are determined according to the second indication information.

In general, the number of repetitions of SIB1 may be 4, 8, or 16. The transport block size carrying the SIB1 may be 208, 328, 440, or 680.

In some possible implementations, for example, when the number of repetitions of SIB1 is 4 or 8, the subframe position of SIB1 on the anchor carrier may be preset.

For example, when the number of repetitions of SIB1 is 4 or 8, any one of subframes 0 to 9 may be preset as a subframe carrying SIB1 on the anchor carrier. That is, when the number of repetitions of SIB1 is 4 or 8, the subframe position of SIB1 on the anchor carrier may be preset to any value from 0 to 9.

In the case that the subframe position of SIB1 on the anchor carrier is preset, the terminal device may be able to determine the subframe position of SIB1 on the anchor carrier without indication information.

In some possible implementations, for example, when the number of repetitions of SIB1 is 16, the subframe position of SIB1 on the anchor carrier may be determined according to the second indication information.

For example, a mapping relationship between the second indication information and the subframe position of SIB1 on the anchor carrier may be preset, and then the subframe position of SIB1 on the anchor carrier may be determined according to the second indication information and the mapping relationship.

An example of the mapping relationship between the second indication information and the number of repetitions of SIB1 and the subframe position of SIB1 on the anchor carrier when SIB1 is transmitted on the anchor carrier is shown in table 1, and the mapping relationship between the second indication information and the transport block size of SIB1 is shown in table 2. In Table 2, I_TBSIndicating the second indication information.

Table 1 mapping relationship between the second indication information and the number of repetitions of SIB1, SIB1 subframe position on anchor carrier when SIB1 is transmitted on anchor carrier

Since the subframe position of SIB1 on the anchor carrier may be preset subframe 0 when the number of repetitions of SIB1 is 4 or 8, table 1 may not include the correspondence relationship between the number of repetitions of SIB1, which is 4 or 8, and subframe 0.

Under the condition that the mapping relationships shown in table 1 and table 2 are preset on the terminal device, and when the second indication information is "0", it may be determined that the number of times of repeating the SIB1 is 4, the subframe position of the SIB1 on the anchor carrier is 0, and the transport block size of the SIB1 is 208; when the second indication information is "4", it may be determined that the number of repetitions of SIB1 is 8, the subframe position of SIB1 on the anchor carrier is 0, and the transport block size of SIB1 is 328. When the second indication information takes other values, the methods for determining the number of times of repeating the SIB1 and the subframe position of the SIB1 on the anchor carrier and the transport block size of the SIB1 are similar and will not be described herein again.

It is described below how the terminal device determines the frequency domain position of the non-anchor carrier and the subframe position of SIB1 on the non-anchor carrier when the terminal device determines that SIB1 is transmitted on the non-anchor carrier according to the first indication information, and determines the number of repetitions of SIB1 and the transport block size of SIB1 according to the second indication information.

Typically, SIB1 is transmitted on a non-anchor carrier, with SIB1 being repeated 8 or 16 times.

In some possible implementations, when the SIB1 is transmitted on the non-anchor carrier, a subframe position of the SIB1 on the non-anchor carrier may be preset, and a frequency domain position of the non-anchor carrier may be determined according to the second indication information.

For example, when SIB1 is transmitted on the non-anchor carrier and the number of repetitions of SIB1 is 8 or 16, the terminal device may determine the frequency domain location of the non-anchor carrier relative to the anchor carrier according to the second indication information.

The subframe position of SIB1 preset on the non-anchor carrier may be preset to any one of "0, 1, 2, 3, 4, 5, 6, 7, 8, and 9".

For example, when the number of repetitions of SIB1 is 8, the subframe position preset on the non-anchor carrier for SIB1 is subframe 0.

For example, when the number of repetitions of SIB1 is 16, the subframe position preset on the non-anchor carrier by SIB1 is subframe 0, or subframe 0 and subframe 9, or subframe 0 and subframe 5. The subframe 0 and the subframe 9 may be located in the same radio frame, and the subframe 0 and the subframe 5 may be located in the same radio frame.

For example, in a case that the frequency domain position of the non-anchor carrier is determined according to the second indication information, the determining, by the terminal device, the frequency domain position of the non-anchor carrier according to the second indication information may include: the terminal device determines the frequency domain position of the non-anchor carrier relative to the anchor carrier according to the second indication information, for example, the frequency domain position of the non-anchor carrier is higher than the frequency domain position of the anchor carrier or the frequency domain position of the non-anchor carrier is lower than the frequency domain position of the anchor carrier; the terminal equipment determines the frequency domain position of the anchor carrier and the offset between the frequency domain position of the non-anchor carrier and the frequency domain position of the anchor carrier; and the terminal equipment determines the frequency domain position of the non-anchor carrier according to the frequency domain position of the non-anchor carrier relative to the anchor carrier, the frequency domain position of the anchor carrier and the offset between the frequency domain positions of the non-anchor carrier and the anchor carrier.

The offset between the frequency domain position of the anchor carrier and the frequency domain positions of the non-anchor carrier and the anchor carrier may be preset or indicated by the indication information.

The offset between the frequency domain position of the anchor carrier and the frequency domain positions of the non-anchor carrier and the anchor carrier may represent an offset between a carrier center of the anchor carrier and a carrier center of the non-anchor carrier, or may represent an offset between a carrier center of the anchor carrier and a carrier edge of the non-anchor carrier on a side close to the anchor carrier, or represent an offset between a carrier edge of the anchor carrier on a side close to the non-anchor carrier and a carrier center of the non-anchor carrier on a side close to the carrier. For example, the offset between the carrier center of the non-anchor carrier and the frequency domain center of the anchor carrier may be preset to be 180kHz, or the offset between the frequency domain center of the non-anchor carrier and the frequency domain location of the anchor carrier center may be preset to be an integer multiple of 180 kHz. Or the offset between the center of the non-anchor carrier and the frequency domain position of the center of the anchor carrier is preset to be 1 Resource Block (RB), or the offset between the center of the non-anchor carrier and the frequency domain position of the center of the anchor carrier is preset to be an integer number of RBs. Where the RB is composed of 12 subcarriers in the frequency domain, and the frequency domain resource represented by the RB is a product of 12 and a subcarrier bandwidth. When the subcarrier bandwidth is 15kHz, 1 RB represents 180 kHz.

For example, the frequency domain position of the anchor carrier may be determined by the synchronization signal, MIB, the offset between the carrier center of the non-anchor carrier and the carrier center frequency domain position of the anchor carrier is 180kHz, and when the frequency domain position of the non-anchor carrier is higher than the frequency domain position of the anchor carrier, it may be determined that the frequency domain position of the non-anchor carrier is located at the high frequency position of the anchor carrier and the frequency center of the non-anchor carrier is 180kHz away from the carrier center of the anchor carrier.

In the embodiment of the present application, the mapping relationship between the second indication information and the number of repetitions of the SIB1, the frequency domain position of the non-anchor carrier with respect to the anchor carrier, and the transport block size of the SIB1 may be preset. The number of repetitions of the SIB1, the frequency domain location of the non-anchor carrier relative to the anchor carrier, and the transport block size of the SIB1 are then determined according to the second indication information.

When SIB1 is transmitted on the non-anchor carrier, one example of the mapping relationship between the second indication information and the number of repetitions of SIB1 and the frequency domain position of the non-anchor carrier with respect to the anchor carrier is shown in table 3, and one example of the mapping relationship between the second indication information and the transport block size of SIB1 is shown in table 2.

Table 3 mapping relationship between the second indication information and the number of repetitions of SIB1, the frequency domain position of the non-anchor carrier with respect to the anchor carrier when SIB1 is transmitted on the non-anchor carrier

For example, when the mapping relationship in tables 3 and 2 is preset on the terminal device, if the second indication information is "0", it may be determined that the number of times of repetition of the SIB1 is 8, the frequency domain position of the non-anchor carrier is higher than the frequency domain position of the anchor carrier, and the transport block size of the SIB1 is 208; if the second indication information is "7", it may be determined that the number of repetitions of the SIB1 is 8, the frequency domain position of the non-anchor carrier is lower than the frequency domain position of the anchor carrier, and the transport block size of the SIB1 is 440; if the second indication is "13", it may be determined that the SIB1 is repeated 16 times, the frequency domain position of the non-anchor carrier is lower than the frequency domain position of the anchor carrier, and the transport block size of the SIB1 is 328. When the second indication information is other values, the methods for determining the number of times of repetition of the SIB1 and the frequency domain position of the non-anchor carrier relative to the anchor carrier and the transport block size of the SIB1 are similar and will not be described herein again.

In some possible implementations, when SIB1 is transmitted on the non-anchor carrier, the subframe location of SIB1 on the non-anchor carrier may be determined according to the second indication information. In this case, the terminal device may receive the third indication information and determine the frequency domain position of the non-anchor carrier according to the third indication information.

Wherein, the terminal device may receive the third indication information through the MIB message. The first indication information, the second indication information and the third indication information may be transmitted through the same MIB message. The third indication information may be 1-bit indication information.

For example, when the SIB1 is transmitted on the non-anchor carrier and the number of repetitions of the SIB1 is 8 or 16, the terminal device may receive the third indication information and determine the frequency domain location of the non-anchor carrier according to the third indication information.

The terminal device determining the frequency domain position of the non-anchor carrier according to the third indication information may include: the terminal device determines the frequency domain position of the non-anchor carrier relative to the anchor carrier according to the third indication information, for example, the frequency domain position of the non-anchor carrier is higher than the frequency domain position of the anchor carrier or the frequency domain position of the non-anchor carrier is lower than the frequency domain position of the anchor carrier; the terminal equipment determines the frequency domain position of the anchor carrier and the offset between the frequency domain position of the non-anchor carrier and the frequency domain position of the anchor carrier; and the terminal equipment determines the frequency domain position of the non-anchor carrier according to the frequency domain position of the non-anchor carrier relative to the anchor carrier, the frequency domain position of the anchor carrier and the offset between the frequency domain positions of the non-anchor carrier and the anchor carrier.

For example, when the third indication information is "0", it may be determined that the frequency domain position of the non-anchor carrier is higher than the frequency domain position of the anchor carrier; when the third indication information is "1", it may be determined that the frequency domain position of the non-anchor carrier is lower than the frequency domain position of the anchor carrier.

Or, when the third indication information is "0", it may be determined that the frequency domain position of the non-anchor carrier is lower than the frequency domain position of the anchor carrier; when the third indication information is "1", it may be determined that the frequency domain position of the non-anchor carrier is higher than the frequency domain position of the anchor carrier.

In the case that the frequency domain position of the non-anchor carrier is determined according to the third indication information, the terminal device may refer to an example that the frequency domain position of the non-anchor carrier is determined according to the frequency domain position of the non-anchor carrier relative to the anchor carrier, the frequency domain position of the anchor carrier, and an offset between the frequency domain position of the non-anchor carrier and the frequency domain position of the anchor carrier, and the example that the frequency domain position of the non-anchor carrier is determined according to the second indication information is not described here again.

In the case that the subframe position of the SIB1 on the non-anchor carrier is determined according to the second indication information, if the number of repetitions of the SIB1 is 16, the terminal device may determine, according to the second indication information, that the subframe position of the SIB1 on the non-anchor carrier is the subframe m, or the subframe m and the subframe n, where m and n are integers greater than or equal to 0 and less than 10.

Wherein m is not equal to n, and the subframe m and the subframe n may be located in the same radio frame.

Under the condition that the subframe position of the SIB1 on the non-anchor carrier is determined according to the second indication information, if the number of repetitions of the SIB1 is 8, the terminal device may determine, according to the second indication information, that the subframe position of the SIB1 on the non-anchor carrier is a subframe x or a subframe y, where x and y are integers greater than or equal to 0 and less than 10, and x and y are not equal to each other.

The subframe x and the subframe y may be located in the same radio frame.

An example of the mapping relationship between the second indication information and the number of repetitions of SIB1, the subframe position of SIB1 on the non-anchor carrier when m is preset to 0 is shown in table 4. In this case, an example of the mapping relationship between the second indication information and the transport block size of the SIB1 is shown in table 2.

TABLE 4 mapping relationship between the second indication information and the number of repetitions of SIB1, SIB1 subframe position on non-anchor carrier when SIB1 is transmitted on non-anchor carrier

For example, when the contents in table 4 and table 2 are preset on the terminal device, and the second indication information is "0", it may be determined that the number of times of repeating the SIB1 is 8, the subframe position of the SIB1 on the non-anchor carrier is x, and the transport block size of the SIB1 is 208; when the second indication information is "4", it may be determined that the number of repetitions of SIB1 is 8, the subframe position of SIB1 on the non-anchor carrier is y, and the transport block size of SIB1 is 328; when the second indication information is "8", it may be determined that the number of repetitions of SIB1 is 16, the subframe position of SIB1 on the non-anchor carrier is m, and the transport block size of SIB1 is 440. When the second indication information is other values, the methods for determining the number of times of repeating the SIB1 and the subframe position of the SIB1 on the non-anchor carrier and the transport block size of the SIB1 are similar and will not be described herein again.

An example of the mapping relationship between the second indication information and the number of repetitions of SIB1, the subframe location of SIB1 on the non-anchor carrier is shown in table 5. The method for the terminal device to determine the number of repetitions of SIB1, the subframe location of SIB1 on the non-anchor carrier, and the transport block size of SIB1 according to the contents in table 5 and the second indication information may refer to the foregoing contents, and will not be described herein again.

TABLE 5 SIB1 mapping relation 2 between the second indication information and the number of repetitions of SIB1, the subframe position of SIB1 on the non-anchor carrier when SIB1 is transmitted on the non-anchor carrier

In table 5, u may have a value of 0, 1, 2, 3, 4, 5, 6, 7, 8 or 9, v may have a value of 0, 1, 2, 3, 4, 5, 6, 7, 8 or 9, and u and v have different values. Subframe u and subframe v may be subframes within the same radio frame.

In table 5, s may take a value of 1, 2, 3, 4, 5, 6, 7, 8, or 9, where subframe 0 and subframe s may be subframes in the same radio frame.

In the case of SIB1 being transmitted on a non-anchor carrier, in some possible implementations, when the number of repetitions of SIB1 is 8, the subframe position of SIB1 on the non-anchor carrier may be preset; when the number of repetitions of SIB1 is 16, the subframe position of SIB1 on the non-anchor carrier may be determined according to the second indication information.

For example, when the number of repetitions of SIB1 is 8, the subframe position of SIB1 on the non-anchor carrier may be preset to subframe 0.

For example, when the number of repetitions of the SIB1 is 16, the terminal device may determine, according to the second indication information, that the subframe position of the SIB1 on the non-anchor carrier is a subframe p, or a subframe p and a subframe q, where p and q are integers greater than or equal to 0 and less than 10, and p and q may be different.

The subframe p and the subframe q may be subframes in the same radio frame.

An example of the mapping relationship between the second indication information and the number of repetitions of SIB1, the subframe location of SIB1 on the non-anchor carrier is shown in table 6. The method for the terminal device to determine the number of repetitions of SIB1, the subframe location of SIB1 on the non-anchor carrier, and the transport block size of SIB1 according to the contents in table 6 and the second indication information may refer to the foregoing contents, and will not be described herein again.

TABLE 6 SIB1 mapping relationship between the second indication information and the number of repetitions of SIB1, and the subframe position of SIB1 on the non-anchor carrier when SIB1 is transmitted on the non-anchor carrier

In table 6, t can take the value 0, 1, 2, 3, 4, 5, 6, 7, 8 or 9.

In table 6, r may take on a value of 1, 2, 3, 4, 5, 6, 7, 8, or 9, where subframe 0 and subframe r may be subframes in the same radio frame.

In table 6, "N/a" indicates that this state is not used and can be used as a reserved state. "N/A" is just one way of marking, and may be marked as "-", or may be marked as "reserved".

The subframe p and the subframe q may be subframes in the same radio frame.

It should be understood that the order of the numerical values in tables 1 to 6 is merely an example and is not limiting. When SIB1 is transmitted on the anchor carrier, the number of times SIB1 is repeated, the subframe position of SIB1 on the anchor carrier, and the mapping relationship between the TBSs of SIB1 may be the same as those in the previous example, and when SIB1 is transmitted on the non-anchor carrier, the number of times SIB1 is repeated, the frequency-domain position of the non-anchor carrier, and the mapping relationship between the TBSs of SIB1 may be the same as those in the previous example.

Table 2 can be differentiated into two identical tables, one for determining the TBS of SIB1 when SIB1 is transmitted on the anchor carrier and the other for determining the TBS of SIB1 when SIB1 is transmitted on the non-anchor carrier.

In another implementation manner, the terminal device receives a MIB message sent by the network device, where the MIB message indicates that SIB1 is transmitted on an anchor carrier or a non-anchor carrier, a subframe location of SIB1 when the SIB is transmitted on the anchor carrier, and a subframe location of SIB1 when the SIB is transmitted on the non-anchor carrier.

Further, the MIB message further includes scheduling information of SIB1, the scheduling information of SIB1 is used to indicate the frequency domain location of SIB1 relative to the anchor carrier at the time of non-anchor carrier transmission, the number of repetitions of SIB1, and the TBS of SIB 1.

The terminal device receives the SIB1 as indicated by the MIB message.

One specific implementation of the MIB message indicating SIB1 includes: the 2bit indicates that SIB1 is transmitted in an anchor carrier or a non-anchor carrier, indicates the subframe location of SIB1 when transmitted in an anchor carrier, and indicates the subframe location of SIB1 in a non-anchor carrier.

Table 7 shows an example of the transmission mode of the SIB1 indicated by the 2bit information in the MIB. Wherein z1 and z2 may be different integers from 0 to 9, and the subframe z1 and the subframe z2 may be subframes in the same radio frame.

When the MIB message indicates that the SIB1 is transmitted on the anchor carrier, the number of repetitions and subframe positions of the indication information in the MIB message and the SIB1 are as shown in tables 8 and 9.

Table 9 TBS and I for carrying SIB1 at anchor carrier transmission_TBSOf (2) a mapping relation

When indicating that SIB1 is transmitted on a non-anchor carrier, the number of repetitions of SIB1 and the manner of indicating the frequency domain location of the non-anchor carrier carrying SIB1 relative to the anchor carrier are shown in table 3. Where "high" indicates that the non-anchor carrier is located at a high frequency position of the anchor carrier, and "low" indicates that the non-anchor carrier is located at a low frequency position of the anchor carrier.

Wherein, regardless of whether SIB1 is transmitted on the anchor carrier or the non-anchor carrier, the TBS of SIB1 may be indicated in the manner of table 2. To determine TBS, I may be set_TBSSame as the higher layer configuration parameter schedulingInfoSIB 1.

In yet another implementation, the terminal device receives a MIB message sent by the network device, where the MIB message indicates that SIB1 is transmitted on an anchor carrier or a non-anchor carrier, and a subframe location of SIB1 at the time of transmission of the anchor carrier or a relative frequency domain location of the non-anchor carrier.

Further, the MIB message may further include scheduling information of SIB1, the scheduling information of SIB1 indicating a frequency domain location of SIB1 with respect to an anchor carrier at the time of non-anchor carrier transmission, a number of repetitions of SIB1, and a TBS of SIB 1.

The terminal device receives SIB1 according to the information indicated by the MIB message.

An exemplary embodiment of the MIB message indicating transmission of SIB1 is as follows: the 2bit indicates that SIB1 is transmitted on an anchor carrier or a non-anchor carrier, the subframe location of SIB1 when transmitted on an anchor carrier or the relative frequency domain location of SIB1 on a non-anchor carrier.

An exemplary manner of indication is shown in table 10.

Table 10 example of an indication of SIB1 transmission

Bit position	Means of
00	The SIB1 also indicates the sub-carrier when the anchor carrier is transmitted with a repetition number of 16The frame position is subframe 0

10	SIB1 transmission on non-anchor carriers located at high frequency locations of anchor carriers
11	SIB1 transmission on non-anchor carrier located at low frequency position of anchor carrier

When indicating that SIB1 is transmitted on the anchor carrier, the manner of indication may be as shown in tables 8 and 9. Of course, the indication may also be made in other ways, and the embodiment of the present application does not limit this.

When indicating transmission of SIB1 on the non-anchor carrier, the number of repetitions of SIB1 and the manner of indicating the subframe position of SIB1 on the non-anchor carrier may be as shown in table 4, table 5, or table 6. And will not be described in detail herein.

In this implementation, the indication of the TBS of SIB1 may refer to table 2 regardless of whether SIB1 is transmitted on an anchor carrier or a non-anchor carrier.

Wherein, to determine TBS, I may be set_TBSSame as the higher layer configuration parameter schedulingInfoSIB 1.

Figure 4 is a schematic block diagram of an apparatus for transmitting SIB1 according to an embodiment of the present application. It should be understood that the apparatus 400 shown in fig. 4 is merely an example,

the apparatus 400 may include a receiving module 410 and a processing module 420.

The apparatus 400 may be used to perform the steps performed by the terminal device in the method shown in fig. 3. One example of the apparatus 400 is a terminal device.

A receiving module 410, configured to receive the first indication information and the second indication information.

The processing module 420 determines from the first indication information whether the SIB1 is transmitted on an anchor carrier or a non-anchor carrier.

The processing module 420 is further configured to: determining a subframe position of the SIB1 on the anchor carrier, determining a number of repetitions of the SIB1 and a transport block size of the SIB1 according to the second indication information, when determining that the SIB1 is transmitted on the anchor carrier, and the receiving module 410 is further configured to: the SIB1 is received on the anchor carrier according to the number of repetitions of the SIB1, the transport block size of the SIB1, and the subframe location of the SIB1 on the anchor carrier.
