Title:
WIRELESS TRANSMISSION DEVICE, WIRELESS RECEPTION DEVICE, AND BANDWIDTH ALLOCATION METHOD
Document Type and Number:
WIPO Patent Application WO/2011/083769
Kind Code:
A1
Abstract:
Provided are a wireless transmission device, a wireless reception device, and a bandwidth allocation method for, when a discontinuous bandwidth allocation is performed, improving the frequency resource use efficiency of a system and thereby improving the system performance. An RIV decoding unit (106) decodes, based on an RIV tree, a start RBG# and a stop RBG# that are indicated by each RIV output from a scheduling information decoding unit (104). An allocation boundary setting unit (107) previously adds a predetermined offset to the boundary of each RIV so that the boundaries of the allocations of respective RIVs are different from each other. Based on the start RBG# and stop RBG# indicated by each RIV output from the RIV decoding unit (106) and the boundaries of the allocations of respective RIVs output from the allocation boundary setting unit (107), a transmission bandwidth determination unit (108) determines, as allocated bandwidths, the bandwidths that are indicated by a plurality of RIVs and are not overlapped with each other.
