Abstract: A base station configures beam identifiers for a plurality of transmission beams. The base station configures virtual beam identifiers for the plurality of transmission beams based on the maximum number of transmission beams from the plurality of transmission beams that may spatially overlap one another, and the beam identifiers. The base station allocates resources using the virtual beam identifiers.

Abstract: A base station of a wireless communication system determines an index of radio resource blocks to which a plurality of random access channels are allocated, and allocates the plurality of random access channels to locations of the determined index of the radio resource blocks such that the radio resource blocks of the plurality of random access channels have a symmetrical structure in available uplink radio resource blocks.
