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.

Abstract: Provided are a method and device for sending control information and receiving control information. The method for sending control information comprises repeatedly sending control information within a scheduling period of the control information M times, wherein the scheduling period is the length of N radio frames, N and M are positive integers greater than 1, and N is greater than or equal to M. The disclosure solves the technical problem in the related art that control information cannot be correctly received in a low-coverage environment and thus a terminal cannot normally access a network, achieving the technical effect of accurately receiving the control information so as to ensure that the network can be accessed normally.
