    Abstract: The present disclosure provides communication apparatus and communication method for trigger-based uplink multi-user transmission. A communication apparatus is provided, the communication apparatus comprising: circuitry, which in operation, generates a trigger frame comprising a common info field and a plurality of user info fields; and a transmitter, which in operation, transmits the generated trigger frame; wherein each of the plurality of user info fields comprises a first field which indicates whether a resource unit (RU) adaptation procedure is disabled for another communication apparatus addressed by the each of the plurality of user info field and a second field which indicates a RU or RU combination allocated to the another communication apparatus.

    Abstract: The invention relates to an improved handover procedure for a mobile terminal. Under control of the target base station, the mobile terminal is to perform a handoff to a target base station, wherein it is to be configured for communication with the target base station via a target radio cell comprising a downlink carrier and an uplink carrier. The mobile terminal receives a handoff command message for the handoff to the target base station including a handoff execution condition as trigger for executing handoff to the target base station. Then, the mobile terminal determines, based on the received handoff execution condition, whether or not the mobile terminal is to trigger execution of the handoff to the target base station. In case the mobile terminal determines that it is to trigger execution of the handoff to the target base station, the mobile terminal executes the handoff to the target base station.

    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.
