1. A method performed by a wireless device, the method comprising:
receiving a first grant that allocates first radio resources for use by the wireless device and a second grant that allocates second radio resources for use by the wireless device, wherein the first radio resources partially overlap in time with the second radio resources;
splitting, at a Medium Access Control (MAC) layer of the wireless device, the first grant into a first non-overlapping grant and a first overlapping grant, wherein the first non-overlapping grant allocates a portion of the first radio resources which do not overlap in time with the second radio resources, and wherein the first overlapping grant allocates another portion of the first radio resources which overlap in time with the second radio resources
generating a first non-overlapping MAC Protocol Data Unit (PDU) for transmission using the first non-overlapping grant;
passing the first non-overlapping MAC PDU from the MAC layer to a physical layer of the wireless device for transmission using the first non-overlapping grant;
generating a first overlapping MAC PDU and a second MAC PDU;
selecting between passing the first overlapping MAC PDU from the MAC layer to the physical layer for transmission using the first overlapping grant or passing the second MAC PDU from the MAC layer to the physical layer for transmission using the second grant, based on respective priorities of the first overlapping grant and the second grant; and
passing the first overlapping MAC PDU from the MAC layer to the physical layer for transmission using the first overlapping grant or passing the second MAC PDU from the MAC layer to the physical layer for transmission using the second grant, according to said selecting.
