    摘要: The present disclosure provides a method and an apparatus for information transmission. The method includes: transmitting information or a channel over one or more of available narrow bands. The available narrow bands include available uplink narrow bands and/or available downlink narrow bands and the available narrow bands are determined based on information including at least one of: a system bandwidth, a cell identity, a position of an anchor carrier, information indicated by a PSS, information indicated by an SSS, information indicated by a MIB and information indicated by a SIB. The information or channel transmitted over the one or more narrow bands includes at least one of: a downlink control channel, a PDSCH, an RAR, a paging message, a SIB, a MIB, a PRACH, a PUSCH, and a PUCCH. The above solution solves the problem regarding how to obtain multiple narrow bands/carriers in NB-IoT and provides a scheme for determining available narrow bands.

    摘要: The present disclosure provides a method and an apparatus for transmission of a synchronization signal. The method includes: transmitting, by a base station, the synchronization signal repeatedly and periodically to a terminal. In one repetition period, the synchronization signal is transmitted over time corresponding to a plurality of Orthogonal Frequency Division Multiplexing (OFDM) symbols in one or more subframes. The synchronization signal is a Primary Synchronization Signal (PSS) or a Secondary Synchronization Signal (SSS). Alternatively, the method includes: receiving, by a terminal, the synchronization signal transmitted from a base station repeatedly and periodically. In this way, the problem associated with inappropriate design of the synchronization signals in the NB-LTE system can be solved and proper transmission of the synchronization signals in the narrow band system can be achieved.

    摘要: Disclosed are a data transmission method and apparatus. The method includes: a transmission node acquiring information about a data transmission mode, herein the information about the data transmission mode includes a rapid data transmission mode in which a time-domain length of data transmission is configured based on a time-domain symbol; and the transmission node transmitting data according to the acquired data transmission mode. In the data transmission method, the time-domain length of data transmission is configured based on the time-domain symbol, the setting of the time-domain length of data transmission is flexible, multiple opportunities of data transmission can exist in one subframe, resources used for data transmission can be guaranteed to be found rapidly when there is a data transmission demand, thus rapid data transmission is realized and data transmission delay is reduced.
