- Abstract
- In this paper, we investigate the situation where the base station (BS) with a wider bandwidth communicates with the multiple user equipments (UEs) of a narrower bandwidth. In the Long Term Evolution (LTE) systems, although the bandwidth of the BS is large enough to contain multiple carrier components (CCs) for the UEs, the BS are not allowed to generate wide baseband signals because the LTE UEs are not designed to extract their CCs from such signals. To take the advantages of wideband operation, we propose a unified baseband signal generation method which covers multiple CCs. The proposed method is related to compensating the phases which are caused by the difference in center frequencies between BS and UEs. In order to reduce computation complexity, we also suggest an efficient technique calculating the phase values for the compensation process.
