Method and device for accessing system information area or network area

A method for accessing a system information area or a network area, comprising:

• determining, by the system information area or the network area, a plurality of initial access signals (IAS);
• and
• transmitting the plurality of IASs by the system information area or the network area, wherein the IAS is used by a terminal having received the IAS to obtain one or more of a subframe boundary, a system bandwidth, a starting frequency and an ending frequency of the system information area or the network area based on the received IAS, wherein
• each IAS of the plurality of IASs comprises a synchronization signal, and the synchronization signal comprised in each IAS of the plurality of IASs comprises a primary synchronization signal (PSS) and a secondary synchronization signal (SSS);
• IASs transmitted at an identical time instant among the plurality of IASs are transmitted at any different frequency positions in a bandwidth of one downlink band occupied by the system information area or the network area, and
• IASs transmitted at different time instants among the plurality of IASs are transmitted with beams having different directions;
• each transmitting position for the plurality of IASs in a subframe is pre-defined by the system information area or the network area with the terminal.

A device for accessing a system information area or a network area, comprising:

• a memory;
• a processor, configured to read a program in the memory to perform following processes:
• receiving a plurality of initial access signals (IAS) transmitted from the system information area or the network area;
• and
• obtaining one or more of a subframe boundary, a system bandwidth, a starting frequency and an ending frequency of the system information area or the network area based on the received IAS;
• and
• a transceiver, configured to receive and transmit data, wherein
• each IAS of the plurality of IASs comprises a synchronization signal, and the synchronization signal comprised in each IAS of the plurality of IASs comprises a primary synchronization signal (PSS) and a secondary synchronization signal (SSS);
• IASs transmitted at an identical time instant among the plurality of IASs are transmitted at any different frequency positions in a bandwidth of one downlink band occupied by the system information area or the network area, and
• IASs transmitted at different time instants among the plurality of IASs are transmitted with beams having different directions;
• each transmitting position for the plurality of IASs in a subframe is pre-defined by the system information area or the network area with the terminal.
