Example 1
As shown in fig. 5 a and 5 b, NPSS (narrow band Primary Synchronization Signal) is transmitted in subframe #0 of a radio frame, and NSSS (narrow band Secondary Synchronization Signal) is transmitted in subframe #5 of an even-numbered radio frame.
A subframe available for transmitting a MIB-NB (Master Information Block-Narrowband) message is subframe #5 of the 2 nd radio frame (i.e., a radio frame in which the remainder of the radio frame number to 4 is equal to 1) in every 4 radio frames.
The sub-frame available for sending the SIB1-NB message is indicated directly by 1-bit signaling in the MIB-NB message.
For example, when the 1-bit signaling value is "0", the subframe available for sending the SIB1-NB message is subframe #5 of the 4 th radio frame (i.e., the radio frame with the remainder equal to 3 obtained by subtracting 4 from the radio frame number) in every 4 radio frames, as shown in fig. 5 (a); when the 1-bit signaling value is "1", the subframe available for sending the SIB1-NB message is subframe 9 of the 4 th radio frame (i.e., the radio frame with the remainder equal to 3, which is obtained by subtracting 4 from the radio frame number) in every 4 radio frames, as shown in fig. 5 (b).
Example 2
As shown in fig. 6(a) and 6(b), NPSS signal is transmitted in subframe #0 of radio frame, NSSS signal is transmitted in subframe #5 of 1 st radio frame (i.e. radio frame number is the remainder of 4, and the remainder is equal to 0) in every 4 radio frames;
the subframe available for transmitting the MIB-NB message is subframe #5 of an odd radio frame.
The sub-frame available for sending the SIB1-NB message is indicated directly by 1-bit signaling in the MIB-NB message.
For example, when the 1-bit signaling value is "0", the subframe available for sending the SIB1-NB message is subframe #5 of the 3rd radio frame (i.e., the radio frame with the remainder equal to 2 obtained by subtracting 4 from the radio frame number) in every 4 radio frames, as shown in fig. 6 (a); when the 1-bit signaling value is "1", the subframe available for transmitting the SIB1-NB message is subframe #9 of the 3rd radio frame (i.e., the radio frame with the remainder equal to 2 obtained by subtracting 4 from the radio frame number) in every 4 radio frames, as shown in fig. 6 (b).
Example 3

The sub-frame available for sending the SIB1-NB message is indicated directly by 1-bit signaling in the MIB-NB message.
For example, when the 1-bit signaling value is "0", the subframe available for sending the SIB1-NB message is subframe #5 of an odd radio frame, as shown in fig. 7 (a); when the 1-bit signaling value is "1", the subframe available for transmitting the SIB1-NB message is subframe #9 of an odd radio frame, as shown in fig. 7 (b).
Example 4
As shown in fig. 8(a) and 8(b), the NPSS signal is transmitted in subframe #0 of the radio frame, and the NSSS signal is transmitted in subframe #5 of the even-numbered radio frame.
The subframe available for transmitting the MIB-NB message is subframe #5 of the 2 nd radio frame (i.e., the remainder of the radio frame number for 4, the remainder being equal to 1) in every 4 radio frames.
The subframe available for transmitting the SIB1-NB message is subframe #5 of the 4 th radio frame (i.e., the radio frame with the remainder equal to 3 obtained by subtracting 4 from the radio frame number) in every 4 radio frames, as shown in fig. 8 (a); alternatively, subframe #5 and subframe #9 of the 4 th radio frame (i.e., the radio frame whose remainder of the radio frame number is equal to 3 with respect to 4) in every 4 radio frames are shown in fig. 8 (b).
In this example, the subframes available for sending the SIB1-NB message may be indicated in any of the following two ways.
The first method is as follows:
directly indicating through 1 bit signaling in the MIB-NB message;
for example, when the 1-bit signaling value is "0", the subframe available for sending the SIB1-NB message is subframe #5 of the 4 th radio frame in every 4 radio frames; when the 1-bit signaling value is "1", the subframes available for transmitting the SIB1-NB message are subframe #5 and subframe #9 of the 4 th radio frame in every 4 radio frames.
The second method comprises the following steps:
signaling an implicit indication by the number of repeated transmissions of the SIB1-NB message (within one scheduling period) in the MIB-NB message;
for example, assuming a first set of values {4,8} and a second set of values {16}, if the number of retransmissions of the SIB1-NB message indicated by the MIB-NB message belongs to the first set of values (i.e., the number of retransmissions is 4 or 8), the subframe available for transmitting the SIB1-NB message is subframe #5 of the 4 th radio frame in every 4 radio frames; if the number of repeated transmissions of the SIB1-NB message belongs to the second set of numbers (i.e. the number of repeated transmissions is 16), the subframes available for sending the SIB1-NB message are subframe #5 and subframe #9 of the 4 th radio frame out of every 4 radio frames.
Example 5
As shown in fig. 9(a) and 9(b), the NPSS signal is transmitted in subframe #0 of the radio frame, and the NSSS signal is transmitted in subframe #5 of the 1 st radio frame (i.e., the remainder of the radio frame number for 4 is equal to 0) in every 4 radio frames.
The subframe available for transmitting the MIB-NB message is subframe #5 of an odd radio frame.
The subframe available for transmitting the SIB1-NB message is subframe #5 of the 3rd radio frame (i.e., the radio frame with the remainder equal to 2 obtained by subtracting 4 from the radio frame number) in every 4 radio frames, as shown in fig. 9 (a); alternatively, subframe #5 and subframe #9 of the 3rd radio frame (i.e., the radio frame with the remainder equal to 2 obtained by subtracting 4 from the radio frame number) in every 4 radio frames are shown in fig. 9 (b).
In this example, the subframes available for sending the SIB1-NB message may be indicated in any of the following two ways.
The first method is as follows:
directly indicating through 1 bit signaling in the MIB-NB message;
when the 1-bit signaling value is "0", the subframe available for sending the SIB1-NB message is subframe #5 of the 3rd radio frame in every 4 radio frames; when the 1-bit signaling value is "1", the subframes available for sending the SIB1-NB message are subframe #5 and subframe #9 of the 3rd radio frame in every 4 radio frames;
the second method comprises the following steps:
signaling an implicit indication by the number of repeated transmissions of the SIB1-NB message (within one scheduling period) in the MIB-NB message;
for example, assume a first set of numerical values {4,8} and a second set of numerical values {16 }; if the number of retransmissions of the SIB1-NB message indicated by the MIB-NB message belongs to the first set of values (i.e. 4 or 8 retransmissions), the subframe available for sending the SIB1-NB message is subframe #5 of the 3rd odd radio frame out of every 4 radio frames; otherwise, if the number of repeated transmissions of the SIB1-NB message belongs to the second set of numbers (i.e., 16), the subframes available for transmitting the SIB1-NB message are subframe #5 and subframe #9 of the 3rd radio frame out of every 4 radio frames.
Example 6
As shown in fig. 10(a) and 10(b), NPSS signals are transmitted in subframe #0 of radio frame, and NSSS signals are transmitted in subframe #5 of the 1 st radio frame (i.e., the remainder of the radio frame number is equal to 0, which is obtained by subtracting 4 from the radio frame number) in every 4 radio frames.
The subframe available for transmitting the MIB-NB message is subframe #5 of the 3rd radio frame (i.e., the remainder of the radio frame number for 4, which is equal to 2) in every 4 radio frames.
The subframe available for sending the SIB1-NB message is subframe #5 of an odd radio frame, as shown in fig. 10 (a); alternatively, subframe #5 and subframe #9 of an odd radio frame are shown in fig. 10 (b).
In this example, the subframes available for sending the SIB1-NB message may be indicated in any of the following two ways.
The first method is as follows:
directly indicating through 1 bit signaling in the MIB-NB message;
when the 1-bit signaling value is "0", the subframe available for sending the SIB1-NB message is subframe #5 of an odd radio frame; when the 1-bit signaling value is "1", the subframes available for transmitting the SIB1-NB message are subframe #5 and subframe #9 of odd radio frames.
The second method comprises the following steps:
signaling an implicit indication by the number of repeated transmissions of the SIB1-NB message (within one scheduling period) in the MIB-NB message;
for example, assume a first set of numerical values {4,8} and a second set of numerical values {16 }; subframe available for sending the SIB1-NB message is subframe #5 of an odd radio frame if the number of repeated transmissions of the SIB1-NB message indicated by the MIB-NB message belongs to the first set of times (i.e., the number of repeated transmissions is 4 or 8); otherwise, if the number of repeated transmissions of the SIB1-NB message belongs to the second set of numbers (i.e., 16), the subframes available for transmitting the SIB1-NB message are subframe #5 and subframe #9 of odd radio frames.
Example 7
As shown in fig. 11(a) and 11(b), NPSS signals are transmitted in subframe #0 of radio frame, and NSSS signals are transmitted in subframe #5 of the 1 st radio frame (i.e., the remainder of the radio frame number is equal to 0, which is the remainder of 4) in every 4 radio frames.
The subframe available for transmitting the MIB-NB message is an odd radio frame subframe #5, as shown in fig. 11 (a); or subframe #9 of an odd radio frame, as shown in fig. 11 (b).
The subframe available for transmitting the SIB1-NB message is subframe #5 of the 3rd radio frame (i.e., the radio frame with the remainder equal to 2 obtained by subtracting 4 from the radio frame number) in every 4 radio frames, as shown in fig. 11 (a); alternatively, subframe #9 is the 3rd radio frame (i.e., the remainder of the radio frame number for 4, the remainder being equal to 2) in every 4 radio frames, as shown in fig. 11 (b).
In this example, a subframe available for transmitting the MIB-NB message and a subframe available for transmitting the SIB1-NB message are indicated simultaneously by the NSSS signal;
wherein, the relationship between the subframe available for transmitting the MIB-NB message and the subframe available for transmitting the SIB1-NB message and the signal sequence d (n) of the NSSS signal satisfies the following formula (1):

Example 8
As shown in fig. 12(a) and 12(b), NPSS signals are transmitted in subframe #0 of radio frame, and NSSS signals are transmitted in subframe #5 of the 1 st radio frame (i.e., the remainder of the radio frame number is equal to 0, which is obtained by subtracting 4 from the radio frame number) in every 4 radio frames.
The subframe available for transmitting the MIB-NB message is an odd radio frame subframe #5, as shown in fig. 12 (a); alternatively, subframe #5 and subframe #9 of an odd radio frame are shown in fig. 12 (b).
The subframe available for transmitting the SIB1-NB message is subframe #5 of the 3rd radio frame (i.e., the radio frame with the remainder equal to 2 obtained by subtracting 4 from the radio frame number) in every 4 radio frames, as shown in fig. 12 (a); or subframe #5 and subframe #9 of the 3rd radio frame (i.e., the remainder of the radio frame number for 4, the remainder being equal to 2) in every 4 radio frames, as shown in fig. 12 (b).
In this example, a subframe available for transmitting the MIB-NB message and a subframe available for transmitting the SIB1-NB message are indicated simultaneously by the NSSS signal;
wherein, the relationship of the above formula (1) is satisfied between the subframe available for transmitting the MIB-NB message and the subframe available for transmitting the SIB1-NB message and the signal sequence d (n) of the NSSS signal.
Wherein if available for transmitting MIB-NB messagesThe sub-frame for information is odd radio frame sub-frame #5 and the sub-frame available for sending the SIB1-NB message is 3rd radio frame sub-frame #5 in every 4 radio frames, then θ f0; if the subframes available for transmitting the MIB-NB are odd radio frame subframe #5 and subframe #9 and the subframes available for transmitting the SIB1-NB are subframe #5 and subframe #9 of the 3rd radio frame in every 4 radio frames, θf＝66/132。
Example 9
As shown in fig. 13(a) and 13(b), the NPSS signal is transmitted in subframe #0 of the radio frame, and the NSSS signal is transmitted in subframe #5 of the even-numbered radio frame;
the subframe available for transmitting the MIB-NB message is subframe #5 of an odd radio frame.
The subframe available for sending the SIB1-NB message is radio frame subframe #9, as shown in fig. 13 (a); alternatively, the subframe available for transmitting the SIB1-NB message is radio frame subframe #6, as shown in fig. 13 (b).
In this example, the subframes available for sending the SIB1-NB message may be indicated by a 1-bit overhead in the MIB-NB message;
for example, when the 1-bit overhead is set to "0", the subframe available for transmitting the SIB1-NB message is radio frame subframe #9, as shown in fig. 13 (a); when the 1-bit overhead is set to "1", a subframe available for transmitting the SIB1-NB message is a radio frame subframe #6, as shown in fig. 13 (b).
Subframe #6 is a downlink subframe or a special subframe; when subframe #6 is a special subframe, OFDM symbols for transmitting the SIB1-NB message may be predefined in subframe # 6. For example, for Guard band or standard independent mode of operation, OFDM (Orthogonal Frequency Division Multiplexing) symbols numbered 0-11 are predefined in subframe #6 as OFDM symbols for sending SIB1-NB messages; for the In-band mode of operation, the OFDM symbols numbered 2-11 are predefined In subframe #6 as OFDM symbols for sending SIB1-NB messages, since the OFDM symbols numbered 0 and 1 need to be used as the LTE (Long Term Evolution) system downlink control area.
Example 10
As shown in fig. 14(a) and 14(b), an NPSS signal is transmitted on subframe #0 of a radio frame; transmitting an NSSS signal on a subframe #5 of a 1 st radio frame (namely, a radio frame with a remainder being equal to 0 by calculating a remainder of a radio frame number to 4) in every 4 radio frames;
the subframe available for transmitting the MIB-NB message is subframe #5 of the 3rd radio frame (i.e., the remainder of the radio frame number for 4, which is equal to 2) in every 4 radio frames.
The subframe available for transmitting the SIB1-NB message is an odd radio frame subframe #5 as shown in fig. 14(a), or a radio frame subframe #9 as shown in fig. 14 (b).
In this example, the subframes available for sending the SIB1-NB message may be indicated in any of the following two ways.
The first method is as follows:
directly indicating through 1 bit signaling in the MIB-NB message;
when the 1-bit signaling value is "0", the subframe available for sending the SIB1-NB message is odd radio frame subframe # 5; when the 1-bit signaling value is "1", the subframe available for sending the SIB1-NB message is radio frame subframe # 9;
the second method comprises the following steps:
the implicit indication is signaled by the number of repeated transmissions of the SIB1-NB message (within one scheduling period) in the MIB-NB message.
For example, assume a first set of numerical values {4,8} and a second set of numerical values {16 }; if the number of retransmissions of the SIB1-NB message indicated by the MIB-NB message belongs to the first set of values (i.e., 4 or 8 retransmissions), the subframe available for sending the SIB1-NB message is odd radio frame subframe # 5; otherwise, if the number of repeated transmissions of the SIB1-NB message belongs to the second set of values (i.e., 16), then the subframe available for sending the SIB1-NB message is radio frame subframe # 9.
Example 11
As shown in fig. 12(a) and 12(b), an NPSS signal is transmitted on subframe #0 of a radio frame; the NSSS signal is transmitted in subframe #5 of the 1 st radio frame (i.e., the radio frame with the remainder equal to 0, obtained by subtracting 4 from the radio frame number) in every 4 radio frames.
The subframe available for transmitting the MIB-NB message is an odd radio frame subframe #5 as shown in fig. 12(a), or subframe #5 and subframe #9 of an odd radio frame as shown in fig. 12 (b).
In this example, the subframes available for transmitting the MIB-NB message are indicated by NSSS signals;
the relation of the above formula (1) is satisfied between the subframe available for transmitting the MIB-NB message and the signal sequence d (n) of the NSSS signal.
Wherein if the subframe available for transmitting the MIB-NB message is an odd radio frame subframe #5, then θ f0; if the subframes available for transmitting the MIB-NB are subframe #5 and subframe #9 of an odd radio frame, θf＝66/132。
In the present example, the subframe available for transmitting the SIB1-NB message is subframe #5 of the 3rd radio frame (i.e., the radio frame number is the remainder of 4, and the remainder is equal to 2) in every 4 radio frames, as shown in fig. 12(a), or subframe #5 and subframe #9 of the 3rd radio frame in every 4 radio frames, as shown in fig. 12 (b).
The subframe available for sending the SIB1-NB message may be directly indicated by 1-bit signaling in the MIB-NB message;
for example, when the 1-bit signaling value is "0", the subframe available for sending the SIB1-NB message is the 3rd radio frame subframe #5 in every 4 radio frames; when the 1-bit signaling value is "1", the subframes available for sending the SIB1-NB message are subframe #5 and subframe #9 of the 3rd radio frame in every 4 radio frames.
In the above example, it is to be noted that:
the subframes used to transmit the SIB1-NB messages are all or part of the subframes available to transmit the SIB1-NB messages;
specifically, the transmission of the SIB1-NB message over all or part of the subframes available for transmission of the SIB1-NB message includes:
firstly, determining whether to transmit SIB1-NB information in all or part of subframes available for transmitting SIB1-NB information according to the repeated transmission times (indicated by the MIB-NB information) in one scheduling period; specifically, when the number of repeated transmission times in one scheduling period is equal to the maximum supportable number of repeated transmission times of all subframes which can be used for sending SIB1-NB messages in one scheduling period, sending SIB1-NB messages on all subframes in the subframes which can be used for sending SIB1-NB messages; when the number of repeated transmission times in one scheduling period is less than the maximum number of repeated transmission times which can be supported by all subframes which can be used for transmitting the SIB1-NB message in one scheduling period, the SIB1-NB message is transmitted on part of subframes in the subframes which can be used for transmitting the SIB1-NB message;
secondly, when the SIB1-NB message is transmitted in a part of subframes available for transmitting the SIB1-NB message, the subframe for transmitting the SIB1-NB message is determined according to a physical cell identity (PCID for short) (that is, if not specifically indicated, the scheduling period is the scheduling period of the SIB1-NB message, and the number of repeated transmissions is the number of repeated transmissions of the SIB1-NB message).
For example, assume that the subframe in which the SIB1-NB message is transmitted is radio frame subframe #9 and the duration of one scheduling period is 256 radio frames; in this case, one scheduling period contains 256 subframes (i.e., radio frame subframe #9) available for transmitting the SIB1-NB message; further assuming that one transmission of the SIB1-NB message occupies 8 subframes, the maximum number of repeated transmissions supportable by a subframe available for transmitting the SIB1-NB message (i.e., radio frame subframe #9) within one scheduling period is 32 (the product of 8 equals 256); transmitting the SIB1-NB message on all subframes (i.e., radio frame subframe #9) of subframes (i.e., radio frame subframe #9) available for transmitting the SIB1-NB message if the number of repeated transmissions within one scheduling period indicated by the MIB-NB message is equal to 32; transmitting the SIB1-NB message on a partial subframe (i.e., subframe #9 of a partial radio frame) of subframes (i.e., radio frame subframe #9) available for transmitting the SIB1-NB message if the number of repeated transmissions within one scheduling period indicated by the MIB-NB message is equal to 16; alternatively, for even physical cell identities, the SIB1-NB message is transmitted on a subframe available for transmission of the SIB1-NB message in an even radio frame (i.e., even radio frame subframe #9) in a subframe available for transmission of the SIB1-NB message; for odd physical cell identities, the SIB1-NB message is sent on a subframe available for sending the SIB1-NB message in an odd radio frame (i.e., odd radio frame subframe #9) of the subframes available for sending the SIB1-NB message.
In the above example, it is to be noted that: the subframe used for transmitting the MIB-NB message is all or part of the subframes which can be used for transmitting the MIB-NB message;
when the MIB-NB message is sent on a part of subframes in the subframe which can be used for sending the MIB-NB message, determining the subframe which is actually used for sending the MIB-NB message in the subframe which can be used for sending the MIB-NB message according to the physical cell identifier; for example, assuming that the subframe available for transmitting the MIB-NB message is subframe #5 of an odd radio frame, for even-numbered physical cell identities, the MIB-NB message is transmitted on a subframe available for transmitting the MIB-NB message in the 1 st odd radio frame of every 2 odd radio frames in the subframe available for transmitting the MIB-NB message (i.e., subframe #5 of a radio frame whose remainder equals 1, where the radio frame number is the remainder of 4); for odd physical cell identities, the MIB-NB message is sent on a subframe available for sending the MIB-NB message in the 2 nd odd radio frame of every 2 odd radio frames in the subframes available for sending the MIB-NB message (i.e., subframe #5 of radio frame with remainder equal to 3, remainder being remainder of radio frame number vs. 4).
The method can enhance the flexibility of sending the system information block 1 message; for example, the network side can be used to send the subframe of the system information block 1 message according to the time delay requirement of the unicast service and the system information acquisition, the inter-cell interference condition, and/or the adjustment of the TDD uplink and downlink configuration adaptability.
Example 12
As shown in fig. 15, the number of SI-NB messages is 6 in this example (denoted SI0-NB, SI1-NB, SI2-NB, SI3-NB, SI4-NB, SI5-NB, respectively); the 6 SIx-NB messages are sent on 6 different carriers, respectively.
The frequency location of the carrier sending the SI-NB message may be indicated by the SIB1-NB message:

Example 13
As shown in fig. 16, the number of SI-NB messages is 6 in this example (denoted SI0-NB, SI1-NB, SI2-NB, SI3-NB, SI4-NB, SI5-NB, respectively); 6 SIx-NB messages are sent on 4 different carriers.
The frequency location of the carrier sending the SI-NB message may be indicated by the SIB1-NB message:
frequency location of carrier transmitting SI0-NB message relative to frequency location f of anchor carrieranchorIs offset0(ii) a Frequency location of a transmitted SI1-NB message carrier relative to frequency location f of an anchor carrieranchorIs offset1(ii) a Frequency location of a transmitted SI2-NB message carrier relative to frequency location f of an anchor carrieranchorIs offset1(ii) a Frequency location of a transmitted SI3-NB message carrier relative to frequency location f of an anchor carrieranchorIs offset2(ii) a Frequency location of a transmitted SI4-NB message carrier relative to frequency location f of an anchor carrieranchorIs offset2(ii) a Frequency location of a transmitted SI5-NB message carrier relative to frequency location f of an anchor carrieranchorIs offset3。
The carrier for sending the SI1-NB and the SI2-NB messages is the same carrier; the carrier on which the SI3-NB and SI4-NB messages are sent is the same carrier.

As shown in fig. 17, the number of SI-NB messages is 6 in this example (denoted SI0-NB, SI1-NB, SI2-NB, SI3-NB, SI4-NB, SI5-NB, respectively); 6 SIx-NB messages are sent on 3 different carriers.
Dividing 6 SI-NB messages into 3 groups; the SI0-NB messages related to radio resource configuration are group 1, the SI1-NB, SI2-NB, and SI3-NB messages related to cell handover are group 2, and the remaining SI4-NB and SI5-NB messages are group 3; SI-NB messages belonging to the same message group are sent on the same carrier.
The frequency location of the carrier sending the SI-NB message may be indicated by the SIB1-NB message:
frequency location of carrier transmitting group 1 message (SI0-NB) relative to frequency location (f) of anchor carrieranchor) Is offset0；
Frequency location of carrier transmitting group 2 messages (SI1-NB, SI2-NB and SI3-NB) relative to frequency location (f) of anchor carrieranchor) Is offset1；
Frequency location of carrier transmitting group 3 messages (SI4-NB and SI5-NB) relative to frequency location of anchor carrier (f)anchor) Is offset2。
Example 15
As shown in fig. 18, the number of SI-NB messages is 6 in this example (denoted SI0-NB, SI1-NB, SI2-NB, SI3-NB, SI4-NB, SI5-NB, respectively); 6 SIx-NB messages are sent on 2 different carriers.
Dividing 6 SI-NB messages into 3 groups; the method comprises the steps that an SI0-NB message related to radio resource configuration is a group 1, an SI 1-NB-SI 3-NB message related to cell handover is a group 2, and the rest of SI4-NB and SI5-NB messages are a group 3; SIx-NB messages belonging to the same message group are sent on the same carrier.
The frequency location of the carrier sending the SI-NB message may be indicated by the SIB1-NB message:
frequency location of carrier transmitting group 1 message (SI0-NB) relative to frequency location (f) of anchor carrieranchor) Is offset0；
Frequency location of carrier transmitting group 2 messages (SI1-NB, SI2-NB and SI3-NB) relative to frequency location (f) of anchor carrieranchor) Is offset1；
Frequency location of carriers transmitting group 3 messages (SI4-NB and SI5-NB) with respect to an anchor carrierFrequency location (f)anchor) Is offset1；
Wherein, the carrier for transmitting the group 2 and group 3 messages is the same carrier.
Example 16
In this example, the number of SI-NB messages is 6 (denoted as SI0-NB, SI1-NB, SI2-NB, SI3-NB, SI4-NB, SI5-NB, respectively); the 6 SIx-NB messages are grouped into 1 group and sent on 1 carrier.
The frequency location of the carrier sending the SI-NB message may be indicated by the SIB1-NB message:
frequency location of carrier transmitting 6 SI-NB messages (as one SI-NB message group) relative to frequency location of anchor carrier (f)anchor) Is offset0。
In the above example, it is to be noted that: frequency position of the carrier sending the one or the group of SI-NB messages relative to frequency position f of the anchor carrieranchorMay be equal to 0; in this case, the one or a set of SI-NB messages are sent on the anchor carrier.
By adopting the method, the flexibility of sending the system information message can be enhanced, for example, when the subframe resource which can be used for sending the downlink service on the carrier for sending the system information block 1 message is less, the network side can select to send all or part of the system information message on the carrier different from the carrier for sending the system information block 1 message, so as to ensure that the carrier for sending the system information block 1 message has enough subframe resource which can be used for sending the downlink service.
It should be noted that the present invention can be embodied in other specific forms, and various changes and modifications can be made by those skilled in the art without departing from the spirit and scope of the invention.
