Abstract: When a UE (102) determines that non-control data needs to be transmitted, the UE will receive a grant that comprises information identifying a resource block (RB) for transmissions by the UE. If the UE determines that the RB is also used for transmitting control data, it will know to transmit only over the portion of the RB used for non-control data transmissions. Rate matching will then be performed on the non-control data that needs to be transmitted and the non-control data will be transmitted only over a portion of the RB. The second portion of the RB will be used for normal control data transmissions by other UEs.
