In an example implementation, a method implemented by a terminal device in a communication system is provided. The method includes identifying a primary anchor carrier on which primary synchronization information is detected in response to receiving the primary synchronization information from a network device at a first point in time. The method also includes detecting indication information from the network device on the identified primary anchor carrier at a second point in time, the second point in time being different from the first point in time. The method also includes determining a presence of a secondary anchor carrier for reception of the system information based on the detection of the indication information.

摘要：【中文】本公开的实施例涉及用于窄带同步信号的发送和窄带系统信息的发送的方法、网络设备和终端设备。在示例实施例中，提供了一种在无线通信系统中的网络设备处实现的方法。根据该方法，在第一锚定载波上向终端设备发送窄带同步信号。确定要在第一锚定载波上还是在第二锚定载波上发送窄带系统信息中的NB‑MIB。第二锚定载波具有相对于第一锚定载波的第一频率偏移。基于该确定，向终端设备发送NB‑MIB。 【EN】Embodiments of the present disclosure relate to a method, a network device, and a terminal device for transmission of a narrowband synchronization signal and transmission of narrowband system information. In an example embodiment, a method implemented at a network device in a wireless communication system is provided. According to the method, a narrowband synchronization signal is transmitted to a terminal device on a first anchor carrier. It is determined whether to transmit the NB-MIB in the narrowband system information on the first anchor carrier or the second anchor carrier. The second anchor carrier has a first frequency offset relative to the first anchor carrier. Based on the determination, an NB-MIB is transmitted to the terminal device.
