Title:
ALLOCATION METHOD AND SIGNAL PROCESSING DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/170764
Kind Code:
A1
Abstract:
An allocation method for allocating each signal to positions on a time axis when transmitting an individual downlink data signal to each of a plurality of terminal stations. The allocation method includes: a tentative allocation step for tentatively allocating an individual downlink data signal to a terminal station the propagation delay time of which is long to a relatively fast timing position and tentatively allocating an individual downlink data signal to a terminal station the propagation delay time of which is short to a relatively slow timing position; a change step in which, when it is estimated that collision occurs when receiving an acknowledge signal transmitted from the terminal station, positions are changed in the allocation in the tentative allocation step so that it is estimated that collision does not occur; and a confirmation step for confirming the position of each individual downlink data signal on the time axis at positions after change in the change step.
