Backward compatible LTE system design for asymmetric uplink/downlink spectrum

摘要

A method of frequency division duplex (FDD) wireless communications asymmetrically maps between downlink and uplink spectrum blocks. Multiple downlink spectrum blocks may be mapped to an uplink spectrum block.

1. A method of frequency division duplex (FDD) wireless communications, comprising:
mapping a control channel region of frequency spectrum for uplink communications to a plurality of blocks of frequency spectrum for downlink communications, by associating uplink physical resource blocks (PRBs) of the control channel region to each downlink spectrum block, the control channel region comprising a first PRB and a second PRB, the first PRB of the control channel region being mapped to a first downlink spectrum block and the second PRB of the control channel region being mapped to a second downlink spectrum block.
