Patent ID: 7085564

Claim:
A multi-cell and multi-user radio communication system comprising: a plurality of cells having a base station enabled for communication, the cells disposed adjacent to or contiguous to one another, wherein the base station collects and manages adjacent cell information from a mobile station within a cell and provides the adjacent cell information collected within the cell to the mobile station; and adjacent cell information management means for managing received adjacent cell information and updating the adjacent cell information if receiving adjacent cell information regarding a same adjacent cell from a plurality of mobile stations, wherein: communication is carried out in each cell by means of a time division multi access system and each base station transmits intra-cell control information at a time division multiple access frame period within the cell; and the adjacent cell information includes a timing offset value of time division multi access frames of its own cell and an adjacent cell, wherein the mobile station carries out reception of intra-cell control information from the adjacent cell at a reception timing which is determined from the timing offset value included in the adjacent cell information acquired from the base station, during an adjacent cell search.
