Abstract: The present disclosure provides a method and an apparatus for transmitting an uplink control signal. The method includes: transmitting M predefined sequences on two transmission symbols within a transmission time interval, and determining an acknowledgement (ACK) message or a negative acknowledgement (NACK) message according to the M predefined sequences and mapping patterns of the M predefined sequences in a time domain and a frequency domain, where M is a positive integer. By means of the above technical solution, a problem that a transmission structure for transmitting the ACK message and the NACK message is imperfect when the transmission time interval is equal to the length of two symbols is solved, and the transmitting of the ACK message and the NACK message when the transmission time interval is equal to the length of two symbols is perfected.

Abstract: 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.
