Device-to-device user equipment for a wireless communication system and resource scheduling method thereof

摘要

A device to device (D2D) user equipment (UE) used for a wireless communication system is provided. The D2D UE is located in a network topology including a plurality of transmitting ends and a plurality of receiving ends. The D2D UE may be a transmitting end or a receiving end. The receiving ends perform a resource scheduling procedure several times according to transmitting end sequences echoed from the transmitting ends to schedule the appropriate resources for the transmitting ends so as to prevent a transmission collision.

1. A device-to-device (D2D) user equipment (UE) for a wireless communication system, the wireless communication system defining a scheduling channel, an echo channel and a plurality of data resource block sets, the scheduling channel comprising a plurality of scheduling resource blocks, the echo channel comprising a plurality of echo resource blocks, the scheduling channel and the echo channel corresponding to each other, the scheduling resource blocks and the data resource block sets corresponding to each other, the D2D UE being located in a network topology that includes a plurality of transmitting ends and a plurality of receiving ends, and the D2D UE being one of the receiving ends, the D2D UE comprising:
a transceiver; a storage, being configured to store resource demand information and a priority value of each of the transmitting ends, and a plurality of transmitting end sequences, wherein each of the transmitting ends corresponds to one of the transmitting end sequences; and a processor electrically connected to the transceiver and the storage, being configured to execute the following operations:
generating a first resource scheduling result according to the resource demand information and the priority value of each of the transmitting ends;sending one of the transmitting end sequences respectively in the scheduling resource blocks via the transceiver according to the first resource scheduling result;receiving at least one of the transmitting end sequences respectively in the echo resource blocks via the transceiver;generating a second resource scheduling result according to the transmitting end sequences received from the echo resource blocks and the priority values of the transmitting ends; andsending one of the transmitting end sequences respectively in the scheduling resource blocks via the transceiver according to the second resource scheduling result.
