Embodiment 1
[0302] The method provided by the embodiment of the present invention can be used in all scenarios where there are multiple sub-channels.
[0303] In the embodiment of the present invention, the system bandwidth is divided into several narrowbands according to preset rules or rules notified by the eNB. The system bandwidth division rules and notification signaling are not limited in the present invention. For example, the system bandwidth is divided into a narrowband every 6 PRBs starting from the lowest PRB index. Information or channels are transmitted by frequency hopping between narrowbands according to a specified pattern. The information may be at least one of the following: SIB, paging message, downlink control information of scheduling paging message, random access preamble, RAR, downlink control information of scheduling RAR, message three, downlink control information, downlink data, uplink Control information, uplink data. The channel may be at least one of the f...
Embodiment 2
[0380] Assume that there are N frequency hopping narrowbands of the information or channel, and the indexes of these N narrowbands are 0, 1.... N-1. For example, if the information refers to the SIB, then the SIB of a cell is sent by frequency hopping on the N narrowbands. For different cells, the N may be different. Further, the N may be determined by at least one of the cell identity and the system bandwidth, for example, for the case where the system bandwidth is greater than or equal to 10MHz, N=4, otherwise N=2. For the definition of frequency hopping narrowband, other embodiments also Be applicable. For the above N narrowbands used for the information or channel frequency hopping, for a certain cell, set the narrowband index corresponding to the information or channel frequency hopping position as H 0 ,H 1 ,..., or it can also be called a frequency hopping sequence, for the kth frequency hopping position H k Determined by:
[0381] h k =Y k modN

Embodiment 3
[0401] Assuming the same as in Embodiment 2, for the above N frequency hopping narrowbands used for the information or channel frequency hopping, for a certain cell, it is set in the wireless frame n rf subframe n sf (such as n rf ∈{0,1...1023},n sf ∈{0,4,5,9} or ∈{0,1,5,6}), where n rf Indicates the wireless frame index, n sf Indicates the subframe index, and the narrowband index corresponding to the information or channel frequency hopping position is Determined by:
[0402]
[0403] Among them, c(i) is a predefined pseudo-random sequence, which adopts Initialize (there are many possibilities for initialization, such as once every 1024 radio frames, after every number of times the network configuration is sent, initialize once. Or it can also be initialized by using the cell identity and / or physical radio frame index and / or physical subframe index .for example
[0404] Example of a pseudo-random sequence: The pseudo-random sequence c(n) is generated by a 31-l...
