Abstract: A method is provided that includes allocating a first subset of resource elements (REs) of a physical resource block (PRB) to a mobile terminal and associating one or more first demodulation reference symbols (DM-RS) ports therewith. The first subset of REs and the one or more first DM-RS ports have common interference characteristics, thereby providing for enhanced interference suppression. The method also includes causing transmission of the PRB for reception by the mobile terminal. Corresponding apparatus and computer program products are also provided.

Abstract: A user equipment UE is configured with an integer value N which defines an effective data rate. The network sends to the UE a grant for uplink transmissions that comprises a resource indication field that allocates N channels each having a same predetermined uplink format and payload capacity. The UE sends N bit sequences on the respective N channels, each bit sequence comprising data and the same predetermined uplink format. In various embodiments: the network specifically configures the UE to receive the predetermined format of the grant; the grant may have an indicator whether the channels are for new data and for the MCS to use; the N channels may be in a same or in adjacent sub frames regardless of the value of N; and there is one MAC header for all the N channels which the network reads as a single MAC PDU.
