Abstract: A system information transmission method in a communication system includes that: a base station configures system information which includes resource mapping information; the base station transmits the resource mapping information through a broadcast control channel. By means of configuring and transmitting the system information, a terminal is able to obtain the resource configuration, mapping and/or allocation conditions of the base station.

Abstract: A resource mapping method is provided, in which a wireless communication system maps subcarriers to resource units through external permutation and internal permutation, the external permutation comprises: performing the first permutation on n physical resource units in every N1 physical resource units, orderly selecting n1×N1 physical resource units from the n physical resource units obtained from the first permutation, and then performing the second permutation on the remaining n?n1×N1 physical resource units in every N2 physical resource units, wherein n, N1, and N2 are all integers greater than or equal to 1, and N1 is not equal to N2, and n1 is an integer greater than or equal to 0. Frequency selectivity gain and frequency diversity gain may be achieved through the present invention by enabling a base station to select a proper resource scheduling granularity and resource unit types, thereby improving the spectrum efficiency of the future wireless communication system.

Abstract: A method for transmitting non-user-specific control information in a wireless communication system includes: in a downlink time period which includes one or more time zones, a base station sends non-user-specific control information in a time zone in which user specific control information is sent; and a terminal obtains and decodes the non-user-specific control information, then obtains information needed to decode user specific control information according to the obtained non-user-specific control information.

Abstract: A method for sub-channelization and resource mapping of wireless resources is provided. The method includes: according to bandwidth features or scheduling features supported by a wireless communication system, determining processes of sub-channelization and resource mapping of wireless resources or parameters of the processes. Therefore, the processes of sub-channelization and resource mapping of wireless resources or the parameters of the processes are different when the bandwidth features or scheduling features are different.
