Abstract: It is disclosed a method and a detector capable of resolving unicast flooding in a layer 2 broadcast domain. The method is performed in a detector having a medium access control (MAC) address. The detector receives a first flooded packet having a destination MAC address differing from the detector's MAC address. The detector sends a message to a node in the layer 2 broadcast domain, wherein the type of the node is determined based on the destination MAC address of the first flooded packet and/or based on whether a destination Internet protocol (IP) address of the first flooded packet is an address within the layer 2 broadcast domain. It is advantageous that the message is adapted to trigger the node to announce its MAC address within the layer 2 broadcast domain, causing the unicast flooding to be resolved, by which consumption of available bandwidth is reduced.

Abstract: Channel state information (CSI) can be transmitted to a network node incrementally to increase network efficiency. The CSI feedback framework can be enhanced by allowing a user equipment (UE) to report multiple sets of CSI feedback, where each set can comprise a rank indicator (RI), a pre-coder matrix indicator (PMI), and a channel quality indicator (CQI). Since a different set may have a different sub-band, the CSI feedback framework can support the sub-band rank, wherein rank data from a wideband and the sub-band can be used by the network.

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.
