A computer readable storage medium storing instructions, wherein when the instructions are executed on a computer in a terminal, cause the computer to: • receive (step 301) physical broadcast channel, PBCH, information, containing basic physical layer configuration information of a cell and first specific content, on a PBCH channel from a base station, wherein the basic physical layer configuration information comprises a system frame number, SFN, information, wherein the first specific content comprises first control information, the first control information including information indicating a time-frequency resource used by the terminal to receive second specific content from the base station, • parse out (step 302) the first specific content from the PBCH information, • parse out (step 303) the first control information from the first specific content, • receive the second specific content from the base station on the time-frequency resource as indicated by the first control information (step 304, step 306), ∘ wherein the second specific content comprises information indicating a time-frequency resource, a coding scheme and a redundancy version used by the terminal to receive third specific content from the base station, • receive the third specific content on the time-frequency resource, with the coding scheme, and with the redundancy version as indicated by the second specific content (step 309), wherein the third specific content includes narrowband configuration information, and the narrowband configuration information comprises information about a narrowband location. • receive (step 301) physical broadcast channel, PBCH, information, containing basic physical layer configuration information of a cell and first specific content, on a PBCH channel from a base station, wherein the basic physical layer configuration information comprises a system frame number, SFN, information, wherein the first specific content comprises first control information, the first control information including information indicating a time-frequency resource used by the terminal to receive second specific content from the base station, • parse out (step 302) the first specific content from the PBCH information, • parse out (step 303) the first control information from the first specific content, • receive the second specific content from the base station on the time-frequency resource as indicated by the first control information (step 304, step 306), ∘ wherein the second specific content comprises information indicating a time-frequency resource, a coding scheme and a redundancy version used by the terminal to receive third specific content from the base station, ∘ wherein the second specific content comprises information indicating a time-frequency resource, a coding scheme and a redundancy version used by the terminal to receive third specific content from the base station, • receive the third specific content on the time-frequency resource, with the coding scheme, and with the redundancy version as indicated by the second specific content (step 309), wherein the third specific content includes narrowband configuration information, and the narrowband configuration information comprises information about a narrowband location.
