Wireless data transmission in multi-carrier system involves selecting sub-carriers of sub-carrier group so at least some are at least preferentially reserved for transmitting data at lower data rate

摘要

The wireless data transmission method involves dividing a frequency band associated with the multi-carrier system into a number of. sub-carrier groups. It involves selecting the sub-carriers (fc + deltaf, fc - deltaf) of the sub-carrier group so that at least some of the sub-carriers are at least preferentially reserved for the transmission of data with a lower data rate. Independent claims are also included for the following: (a) a radio transmitter/receiver arrangement for wireless data transmission in a multi-carrier system; (b) a mobile terminal; and (c) and a base station.
