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: A method for providing scheduling request resources to a user equipment involves a wireless network node (e.g., an eNB) transmitting a configuration of scheduling request resources to the user equipment via radio resource control signaling, and the wireless network node enabling the scheduling request resources by transmitting a message to the user equipment via physical layer signaling. The message that enables the scheduling request resources may be transmitted as part of an uplink grant or downlink grant. In some implementations, the enabling message maps to one of several sets of scheduling request resources, which the wireless network node has previously communicated to the user equipment via radio resource control signaling. In other implementations, the selection of which set of scheduling request resources is to be enabling is made by the user equipment based on implicit signaling from the wireless node.
