Determining the second resource in any one of the following ways:

the second resource is a candidate resource of the second resource;

The second resource is a fixed subset of candidate resources of the second resource;

the second resource is a subset of candidate resources of the second resource, wherein the subset is determined according to the candidate resources of the second resource and a cell identity.

Wherein the cell identity is an identity of a cell transmitting the data.

In one embodiment, when the data is primary synchronization signal data, the primary synchronization signal data is indicated to be sent on the first resource and the second resource by a system information block 1; or alternatively

When the data is secondary synchronization signal data, the secondary synchronization signal data is indicated to be sent on the first resource and the second resource through a primary synchronization signal or a system information block 1; or alternatively

When the data is main information block data, the main information block data is sent on the first resource and the second resource through a main synchronous signal, a secondary synchronous signal or a system information block 1 indication; or alternatively

When the data is system information block 1 data, the system information block 1 data is sent on the first resource and the second resource through a main synchronization signal, a secondary synchronization signal, a main information block or a system information block 1 indication.

For example, taking the system information block 1 data of the first frequency division duplex FDD system as an example, the period of one system information block 1 data is 256 radio frames, the retransmission transmission times are 16 times, and each repeated transmission corresponds to 16 continuous radio frames; it is assumed that the first resource for transmitting the system information block 1 is subframe 4 of each even radio frame of the anchor carrier and the second resource for transmitting the system information block 1 is subframe 4 of an odd radio frame having a remainder of 1 for radio frame number 4 of the anchor carrier.

In this case, if resource mapping of the system information block 1 on the first resource and the second resource is independently performed, the system information block 1 performs a channel coding/modulation operation according to the number of modulation symbols that can be carried by the first resource (i.e., subframe 4 of 8 even-numbered radio frames among the consecutive 16 radio frames) and maps the output modulation symbols to available resource units of the first resource; the channel coding/modulation operation is performed according to the number of modulation symbols that can be carried by the second resource (i.e., subframe 4 of 4 odd-numbered radio frames of the consecutive 16 radio frames) and the output modulation symbols are mapped to available resource units of the second resource.

If the resource mapping of the system information block 1 on the first resource and the second resource is jointly performed, the system information block 1 performs a channel coding/modulation operation according to the total number of modulation symbols that can be carried by the first resource (i.e., the subframe 4 of 8 even radio frames in the continuous 16 radio frames) and the second resource (i.e., the subframe 4 of 4 odd radio frames in the continuous 16 radio frames), and maps the output modulation symbols to the available resource units of the first resource first and then to the available resource units of the second resource.

The first resource for transmitting the primary information block is subframe 0 of each radio frame of the anchor carrier. The second resource for transmitting the primary information block is subframe 9 of each odd radio frame of the anchor carrier.

Alternatively, the primary information block is indicated by the secondary synchronization signal to be transmitted on the first resource only or on the first resource and the second resource; if the symbol carried by the secondary synchronization signal sequence is 1, it means that the primary information block is only transmitted on the first resource, and if the symbol carried by the secondary synchronization signal sequence is not 1 (e.g., -1), it means that the primary information block is transmitted on the first resource and the second resource.

Example 2

Fig. 6 is a schematic diagram two of an NB-IoT system transmitting primary information blocks on a first resource and a second resource.

As shown in fig. 6, the period of one main information block includes 64 radio frames.

The first resource for transmitting the primary information block is subframe 0 of each radio frame of the anchor carrier. The second resource for transmitting the primary information block is dependent on the cell identity. When the cell identity is even in value, the second resource for transmitting the primary information block is subframe 4 of each odd radio frame of the anchor carrier (as shown in fig. 6 (a)); when the cell identity value is odd, the second resource for transmitting the primary information block is subframe 4 of each even radio frame of the anchor carrier (as shown in fig. 6 (b)).

Wherein the cell identity is determined from the secondary synchronization signal sequence.

As shown in fig. 9, one system information block 1 period includes 256 radio frames.

When the cell identity is even and the first resource for transmitting the system information block 1 is the subframe 4 of each even radio frame of the anchor carrier, the second resource for transmitting the system information block 1 depends on the cell identity. Specifically, when the remainder of the cell identification value pair 4 is equal to 0, the second resource for transmitting the system information block 1 is the subframe 4 of the odd radio frame where the remainder is equal to 1 for the radio frame number pair 4 of the anchor carrier (as shown in (a) of fig. 9); when the remainder of the cell identity value pair 4 is equal to 2, the second resource for transmitting the system information block 1 is the subframe 4 of the odd radio frame where the remainder is equal to 3 for the radio frame number pair 4 of the anchor carrier (as shown in (b) of fig. 9).

When the cell identity is odd and the first resource for transmitting the system information block 1 is the subframe 4 of each odd radio frame of the anchor carrier, the second resource for transmitting the system information block 1 depends on the cell identity. Specifically, when the remainder of the cell identification value pair 4 is equal to 1, the second resource for transmitting the system information block 1 is the subframe 4 of the even radio frame where the remainder is equal to 0 for the radio frame number pair 4 of the anchor carrier (as shown in (c) of fig. 9); when the remainder of the cell identity value pair 4 is equal to 3, the second resource for transmitting the system information block 1 is the subframe 4 of the even-numbered radio frame where the remainder is equal to 2 for the radio frame number pair 4 of the anchor carrier (as shown in (d) of fig. 9).

Alternatively, the system information block 1 is indicated by the master information block as being transmitted on the first resource only or on the first resource and the second resource. Optionally, the primary information block signaling for indicating whether system information block 1 is sent on the first resource only or on the first resource and the second resource is encoded in combination with a transport block size of system information block 1 and a repetition number of transmissions of system information block 1 as shown in table 1 below (assuming a 4bit overhead).

With respect to table 1 below, it should also be noted that:

The sub-frame 4 of each even radio frame whose cell identification value is even and for transmitting the system information block 1 is the anchor carrier corresponds to the case where the number of repeated transmissions is configured to be 16, and the sub-frame 4 of each odd radio frame whose cell identification value is odd and for transmitting the system information block 1 is the anchor carrier also corresponds to the case where the number of repeated transmissions is configured to be 16 (transmissions within the range of consecutive 16 radio frames of one system information block 1 period are regarded as one repeated transmission). In the case where the number of repeated transmissions is configured to be 16, the system information block 1 is transmitted on the first resource only or on the first resource and the second resource. In the case where the number of repeated transmissions of the system information block 1 is configured to be 4 or 8, the system information block 1 is transmitted on the first resource by default only.

Example 6

Fig. 10 is a schematic diagram of an eMTC system transmitting a system information block 1 on a first resource and a second resource.

As shown in fig. 10, the period of one system information block 1 includes 8 radio frames. When the cell identity is even and the first resource for transmitting the system information block 1 is the subframe 4 and the subframe 9 of each radio frame, the second resource for transmitting the system information block 1 is the subframe 5 of each even radio frame (as shown in (a) of fig. 10); when the cell identity is odd and the first resource for transmitting the system information block 1 is the sub-frame 0 and the sub-frame 9 of each radio frame, the second resource for transmitting the system information block 1 is the sub-frame 5 of each odd radio frame (as shown in (b) of fig. 10).

Alternatively, the system information block 1 is indicated by the master information block as being transmitted on the first resource only or on the first resource and the second resource. Optionally, the primary information block signaling for indicating whether system information block 1 is sent on the first resource only or on the first resource and the second resource is encoded in combination with a transport block size of system information block 1 and a repetition number of transmissions of system information block 1 as shown in table 2 below (assuming a 5 bit overhead).

With respect to table 2 below, it should also be noted that:

The first resource for transmitting the system information block 1 with the cell identification value being even is a case where the number of repeated transmissions of the sub-frame 4 and the sub-frame 9 of each radio frame is configured to be 16, and the first resource for transmitting the system information block 1 with the cell identification value being odd is a case where the number of repeated transmissions of the sub-frame 0 and the sub-frame 9 of each radio frame is also configured to be 16. In the case where the number of repeated transmissions is configured to be 16, the system information block 1 may be transmitted on the first resource or on the first resource and the second resource. In the case where the number of repeated transmissions of the system information block 1 is configured to be 4 or 8, the system information block 1 can be transmitted only on the first resource by default.

TABLE 2

Example 7

Fig. 11 is a schematic diagram of an NB-IoT system transmitting system information block 1 on a second resource of a non-anchor carrier.

As shown in fig. 11, the period of one system information block 1 includes 256 radio frames.

When the cell identity is even and the first resource for transmitting the system information block 1 is the subframe 4 of each even radio frame of the anchor carrier, the second resource for transmitting the system information block 1 is the subframe 5 of each odd radio frame of one non-anchor carrier (as shown in (a) of fig. 11); when the cell identity is odd and the first resource for transmitting the system information block 1 is the subframe 4 of each odd radio frame of the anchor carrier, the second resource for transmitting the system information block 1 is the subframe 5 of each even radio frame of one non-anchor carrier (as shown in (b) of fig. 11).

Alternatively, it is indicated by the system information block 1 whether the system information block 1 is transmitted on the first resource only or on the first resource and the second resource. If the system information block 1 is sent on the first resource and the second resource, the frequency interval between the non-anchor carrier where the second resource is located and the anchor carrier where the first resource is located is fixed, or the frequency position of the non-anchor carrier where the second resource is located is indicated by the system information block 1. When the frequency interval between the non-anchor carrier wave where the second resource is located and the anchor carrier wave where the first resource is located is fixed, the frequency position of the non-anchor carrier wave can be indirectly obtained according to the frequency position of the anchor carrier wave.

Example 8

Fig. 12 is a schematic diagram of an NB-IoT system transmitting primary synchronization signals on a first resource and a second resource.

As shown in fig. 12, one period of the primary synchronization signal includes 1 radio frame. The first resource for transmitting the primary synchronization signal is subframe 5 of each radio frame of the anchor carrier; the second resource for transmitting the primary synchronization signal is subframe 6 of each radio frame of the anchor carrier.

Determining a sequence of primary synchronization signal usage on the first resource according to the following equation (1-1):

u＝5,l＝3,…,13，

Where l represents an OFDM symbol index;

the values of S (l) for the different OFDM symbol indexes are shown in table 3 below.

S(3)	S(4)	S(5)	S(6)	S(7)	S(8)	S(9)	S(10)	S(11)	S(12)	S(13)
											1	1	1	1	-1	-1	1	1	1	-1	1

TABLE 3 Table 3

It should be noted that, the formula (1-1) provides a truncated primary synchronization signal sequence on each OFDM symbol of the transmission primary synchronization signal of one subframe in sequence; from the perspective of the subframe, the primary synchronization signal sequence d can be expressed as the following formula (1-2):

in this case, if the sequence rep (p, 11) after 11 repetitions of the sequence p is regarded as the base sequence of the primary synchronization signal, the primary synchronization signal sequence d can be regarded as the sequence after scrambling operation of the base sequence of the primary synchronization signal according to the following scrambling code (see the formula (1-3):

[rep(S(3),11),rep(S(4),11),…,rep(S(13),11)]。 (1-3)

Determining a sequence of primary synchronization signal usage on the second resource according to the following equation (1-4):

u＝5,l＝3,…,13，

Where l represents an OFDM symbol index;

The values of S (l) for the different OFDM symbol indexes are shown in table 4 below.

S(3)	S(4)	S(5)	S(6)	S(7)	S(8)	S(9)	S(10)	S(11)	S(12)	S(13)
											-1	-1	1	1	1	-1	-1	-1	1	1	-1

TABLE 4 Table 4

It should be noted that, the formula (1-4) provides a truncated primary synchronization signal sequence on each OFDM symbol of the transmission primary synchronization signal of one subframe in sequence; from a subframe perspective, the primary synchronization signal sequence d can be expressed as the following equation (1-5):

In this case, if the sequence rep (p, 11) after 11 repetitions of the sequence p is regarded as the base sequence of the primary synchronization signal, the primary synchronization signal sequence d can be regarded as the sequence after scrambling operation of the base sequence of the primary synchronization signal according to the following scrambling code (see the formula (1-6):

[rep(S(3),11),rep(S(4),11),…,rep(S(13),11)]。 (1-6)

Finally, the primary synchronization signal sequence on the second resource and the primary synchronization signal sequence on the first resource correspond to the same primary synchronization signal base sequence, but correspond to different scrambling sequences (the scrambling sequence corresponding to the primary synchronization signal sequence on the first resource depends on table 3, the scrambling sequence corresponding to the primary synchronization signal sequence on the second resource depends on table 4), resulting in a primary synchronization signal on the first resource that differs from the primary synchronization signal used sequence on the second resource.

Example 9

Fig. 13 is a schematic diagram of an NB-IoT system transmitting secondary synchronization signals on a first resource and a second resource.

As shown in fig. 13, one period of the secondary synchronization signal includes 8 radio frames. The first resource for transmitting the secondary synchronization signal is subframe 9 of each even radio frame of the anchor carrier; the second resource for transmitting the secondary synchronization signal is subframe 9 of each odd radio frame of the anchor carrier.

Alternatively, the secondary synchronization signal is indicated by the primary synchronization signal to be sent on the first resource only or on the first resource and the second resource; if the symbol carried by the primary synchronization signal sequence is 1, it means that the secondary synchronization signal is only transmitted on the first resource, and if the symbol carried by the primary synchronization signal sequence is not 1 (e.g., -1), it means that the secondary synchronization signal is transmitted on the first resource and the second resource.

Determining a sequence of secondary synchronization signal usage on the first resource according to the following equation (2-1):

Wherein the binary sequence b _q (m) is shown in table 5 below.

TABLE 5

In this case, from the perspective of the subframe, if the sequence p (n) is regarded as the base sequence of the secondary synchronization signal, the sequence d (n) of the secondary synchronization signal can be regarded as the base sequence of the primary synchronization signal according to the scrambling sequenceAnd performing a sequence after scrambling operation.

Determining a sequence of secondary synchronization signal usage on the second resource according to the following equation (2-2):

Wherein the binary sequence b _q (m) is shown in table 5 above.

Finally, the secondary synchronization signal sequence on the second resource and the secondary synchronization signal sequence on the first resource correspond to the same base sequence of the secondary synchronization signal, but correspond to different scrambling sequences (the scrambling sequences corresponding to the secondary synchronization signal sequence on the first resource and the secondary synchronization signal sequence on the second resource are defined in dependence on different θ _f), resulting in a secondary synchronization signal on the first resource being different from the sequence used by the secondary synchronization signal on the second resource.
