    Abstract: A method allocates radio resources for a transmitting user equipment (UE) to perform direct communication transmissions over a direct sidelink connection to one or more receiving UEs. At least two sidelink grant processes are provided in the transmitting UE for the transmitting UE to handle at least two sidelink grants within the same transmission control period. Each one of the sidelink grant processes is associated with an identification and can be associated with one sidelink grant. The transmitting UE acquires at least two sidelink grants and associates each of the acquired sidelink grants with one sidelink grant process. For each sidelink grant, the transmitting UE allocates radio resources according to the respective sidelink grant to perform a direct communication transmission of sidelink control information and of data over the direct sidelink connection. The transmitting UE performs a direct communication transmission per acquired sidelink grant within the same transmission control period.

  • Patent number: 12096467
    Abstract: The invention relates to a transmitting device, which performs a resource sensing procedure to acquire information about radio resources usable for transmitting data at a later point in time. After data becomes available for transmission, the transmitting device performs an autonomous radio resource allocation to select radio resources within a transmission window to be used for transmitting the data, based on the information acquired by the resource sensing procedure during a sensing window. The autonomous radio resource allocation comprises selecting radio resources in primary subframes of the transmission window preferably over radio resources in secondary subframes of the transmission window.
