Abstract

The invention discloses a method for acquiring indication information of an adjacent cell and a wireless access network system. The method comprises the following steps: a terminal acquires relevant information of a microcell keeping time synchronization with a macrocell from the macrocell; the terminal transmits detection signals of the adjacent cell according to the acquired relevant information of the microcell; a wireless panel node of the microcell respectively receives the detection signals of the adjacent cell in the same frequency band and time slot, processes the detection signals of the adjacent cell to generate the indication information of the adjacent cell of an adjacent cell aggregation comprising the terminal and transmits the indication information of the adjacent cell to the terminal; and the terminal acquires the indication information of the adjacent cell. Each embodiment of the invention can solve the defects of long search time for acquiring a list of the adjacent cell and high power consumption existing in the prior art, and effectively shortens the time for acquiring the list of the adjacent cell by the terminal.

Description

technical field [0001] The present invention relates to the field of wireless communication, in particular to a method for acquiring indication information of neighboring cells and a wireless access network system. Background technique [0002] In order to perform functions such as handover, inter-cell scheduling, and inter-cell interference coordination for the terminal, the radio access network needs to dynamically grasp the set of neighboring cells (such as a neighboring cell list) of the cell where the terminal is located. In a traditional wireless access network, the neighbor cell indication information is sent to the terminal by the base station of the cell where the terminal is located after the terminal completes the cell search. Under normal circumstances, the number of cells in the adjacent cell indication information (including the set of adjacent cell lists) sent by the base station is less than 10, and the terminal detects the pilot signal power of all cells aft...
