FORMATION OF TIMING ADVANCE GROUPS FOR CARRIER AGGREGATION IN HETEROGENEOUS NETWORK Russian patent published in 2015 - IPC H04W72/04 

FIELD: radio engineering, communication.

SUBSTANCE: invention relates to wireless communication. The technology for formation of timing advance groups for carrier aggregation in heterogeneous network (HetNet) is described. One method involves the stages, at which: at least, a cell of the first carrier component is assigned to the first timing advance group or the second timing advance group. At least, a cell of the second carrier component is assigned to the first timing advance group or to the second timing advance group. Separate value of the timing advance index is selected for each of the first and second timing advance groups. The value of timing advance index is used for designation of timing advance group for signal transmission in HetNet.

EFFECT: elimination of the disadvantage consisting in formation of difference of temporary characteristics at reception of signals.
