Abstract: A user equipment receives a first uplink grant and a second uplink grant from a base station. The first uplink grant assigns first uplink resources, and the second uplink grant assigns second uplink resources. The first uplink resources and the second uplink resources overlap within a time interval. The user equipment determines whether the transmission of second data has priority over that of first data. When determining that the transmission of the second data has priority over that of the first data, the user equipment determines one of the first uplink resources and the second uplink resources as the designated resources of the second data, and transmits the second data to the base station according to the designated resources within the time interval.

Abstract: A user equipment (UE) and a base station (BS) for a mobile communication system are provided. The UE performs a random access (RA) procedure with the BS in a radio resource control (RRC) idle mode. The UE transmits a preconfigured uplink resource request message to the BS and receives a configuration message indicating a preconfigured uplink resource from the BS. The UE starts a time alignment timer (TAT) which is used for the RRC idle mode in response to the RA procedure. When the UE determines that there exists an uplink message to be transmitted in the RRC idle mode and determines that the current timing advance (TA) value is valid, the UE transmits the uplink message on the preconfigured uplink resource.

Abstract: The invention relates to a user equipment of device-to-device communications and a resource selection method thereof. The user equipment includes a resource selection device and a transceiver device. The resource selection device is configured to create a state machine model, which includes an in-coverage state and an out-of-coverage state corresponding to a base station. The resource selection device is also configured to select a corresponding device-to-device communication resource in response to a current state of the user equipment during transferring of the user equipment from the in-coverage state to the out-of-coverage state or from the out-of-coverage state to the in-coverage state. The transceiver device is configured to perform a device-to-device communication with another user equipment according to the corresponding device-to-device communication resource. The resource selection method includes the steps corresponding to the operations of the user equipment.

Abstract: The present invention relates to a resource allocation apparatus, resource allocation method, and non-transitory computer readable medium thereof. The resource allocation apparatus adapted for a network comprising a femto base station (BS) which communicates with the femto BS and includes a storage, a transceiver and a processor connected to the storage and the transceiver. The storage stores a random function, reuse information and fractional frequency reuse (FFR) information which records an original cell ID/frequency corresponding relation of an unoccupied partition of the network. The processor selects a time partition from the unoccupied partition according to the random function and the reuse information, changes the original cell ID/frequency corresponding relation to generate a changed cell ID/frequency corresponding relation according to the FFR information; and generates an allocation message according to the time partition and the changed cell ID/frequency corresponding relation, wherein the transceiver conveys the allocation message to the femto BS.
