Abstract: A resource mapping method and an apparatus are provided relating to the communications field, the solutions capable of flexibly implementing resource mapping of a channel or a signal. In one example implementation, first information is obtained that is used to indicate a cyclic shift start resource block location or a cyclic shift end resource block location for resource mapping of a first channel or a first signal in a resource block cyclic shift manner in a bandwidth used by user equipment. A resource mapping location of the first channel or the first signal in the bandwidth used by the user equipment is determined according to the resource block cyclic shift manner and the first information. The first channel or the first signal is received or sent at the resource mapping location. The resource mapping method and the apparatus are used to map a resource.

Abstract: The present invention provides an information transmission method and an apparatus, so as to resolve a problem of high power consumption of a base station resulted from excessively high information overheads for transmitting an MIB by the base station. The method includes: generating, by a base station, an MIB including first bandwidth indication information and a radio frame configuration field; and sending the MIB using a time-frequency resource in a radio frame. Compared with a conventional MIB including a plurality of configuration parameters such as system bandwidth information, a frame number of a radio frame for transmitting the MIB, and PHICH configuration information, the MIB transmitted by the base station in embodiments of the present invention includes two configuration parameters: the first bandwidth indication information and the radio frame configuration field.
