Base station and method for resource allocation using localized and distributed resource blocks

摘要

Embodiments of a base station and method for resource allocation using localized and distributed resource blocks are generally described herein. The base station comprises processing circuitry to allocate localized resources to user stations based on receipt of channel quality information received from the user stations and to allocate distributed resource to user stations based on non-receipt of channel quality information. The base station also comprises physical layer circuitry to transmit control information on a physical channel to indicate the resources that are allocated to each scheduled user station.

1. An apparatus of an eNodeB arranged for resource allocation in an orthogonal-frequency division multiple access (OFDMA) network, the apparatus comprising transceiver circuitry and processing circuitry arranged to:
receive uplink signals including reporting information that includes at least a channel quality indicator (CQI) from user equipment (UEs), the CQI comprising an indication of channel quality for a channel comprising a plurality of subcarriers; assign virtual resource blocks (VRBs) to the UEs, wherein some of the UEs are assigned VRBs of a localized type and some other of the UEs are assigned VRBs of a distributed type; map the VRBs to physical resource blocks (PRBs), each PRB comprising a group of two or more adjacent subcarriers, the VRBs of the localized type being mapped to contiguous PRBs and the VRBs of the distributed type being mapped to non-contiguous PRBs; provide downlink control signaling to each of the UEs to indicate whether VRBs of the localized type or VRBs of the distributed type have been assigned and to schedule channel resources for communication; and communicate with the scheduled UEs in accordance with a multiple-input multiple output (MIMO) technique using multiple antennas in which downlink signals are precoded for beamforming based at least in part on the reporting information, the downlink signals comprising downlink subframes of six OFDM symbols.
