Abstract: A user equipment (UE) receives downlink data using resource blocks in a wireless mobile communication system. The UE receives downlink control information including resource allocation information and downlink data mapped to physical resource blocks (PRBs) based on the downlink control information. The resource allocation information indicates virtual resource block (VRB) allocations for the UE. Indexes of the PRBs to which the downlink data are mapped are determined based on a mapping relationship between virtual resource blocks (VRBs) and the PRBs. The mapping relationship is defined based on indexes of the VRBs which are mapped to the indexes of the PRBs for a first slot of a subframe and a second slot of the subframe. The indexes of the PRBs for the second slot are shifted with respect to the indexes of the PRBs for the first slot based on a predetermined gap. The mapping relationship includes a transformation of VRB indexes based on a matrix.

Abstract: A user equipment (UE) receives downlink data using resource blocks in a wireless mobile communication system. The UE receives downlink control information including resource allocation information and downlink data mapped to physical resource blocks (PRBs) based on the downlink control information. The resource allocation information indicates virtual resource block (VRB) allocations for the UE. A resource block pair includes a first resource block associated with a first time slot and a second resource block associated with a second time slot adjacent to the first time slot. The first and second resource blocks are allocated to the same frequency indices. A mapping between VRB pairs and PRB pairs exists such that frequency consecutive VRB pairs are mapped to non-frequency consecutive PRB pairs and that each resource block pair is split so there is a frequency gap between the first and second parts of the resource block pair.

Abstract: A user equipment (UE) receives downlink data using resource blocks in a wireless mobile communication system. The UE includes data processing circuitry coupled to a receiver that receives downlink control information including resource allocation information for the downlink data from a base station and to receive the downlink data mapped to physical resource blocks (PRBs) based on the downlink control information. The resource allocation information indicates virtual resource block (VRB) allocations for the user equipment. Each resource block corresponds to one time slot. A resource block pair includes a first resource block associated with a first time slot and a second resource block associated with a second time slot adjacent to the first time slot. The first and second resource blocks are allocated to the same frequency indices. A mapping relationship between VRB pairs and PRB pairs exists such that frequency consecutive VRB pairs are mapped to non-frequency consecutive PRB pairs and that each resource block pair is split so there is a frequency gap between the first and second parts of the resource block pair. The resource allocation information indicates the frequency gap size is one of a first value and a second different value.

Abstract: In a wireless mobile communication system, user equipment receives downlink data and downlink control information including resource allocation information for the downlink data from a base station. Downlink data is mapped to physical resource blocks (PRBs) based on the downlink control information. The resource allocation information indicates virtual resource block (VRB) allocations for the user equipment. Indexes of PRBs to which the downlink data are mapped are determined based on mapping relationship between VRBs and the PRBs. The mapping relationship is defined such that indexes of the VRBs are mapped to indexes of the PRBs for a first part and a second part of a subframe. The received downlink control information includes control information that determines whether the indexes of the PRBs for the second part are separated with respect to the indexes of the PRBs for the first part based on a predetermined gap in a distributed mode where distributed VRBs are used or whether the indexes of the PRBs for the second part are not separated with respect to the indexes of the PRBs for the first part in a non-distributed mode where localized VRBs are used.
