COMMUNICATION SYSTEM, BASE STATION, AND COMMUNICATION TERMINAL

摘要

A communication system includes a base station, a first communication terminal, and a second communication terminal, wherein the base station notifies the second communication terminal of a wireless resource allocation result using control information including a first region, a second region, and a third region, sets the second region and the third region to have values in a first specific combination when notifying, using the first region, the second communication terminal of a first allocation result of a first wireless resource allocated to communication between the base station and the second communication terminal, and sets the second region and the third region to have values in a second specific combination different from the first specific combination when notifying, using the first region, the second communication terminal of a second allocation result of a second wireless resource allocated to direct communication between the second communication terminal and the first communication terminal.

主权项

1. A communication system comprising:
a base station; a first communication terminal; and a second communication terminal capable of communicating with the base station and directly communicating with the first communication terminal without routing communication signal through the base station, wherein the base station is configured to:
notify the second communication terminal of a wireless resource allocation result by using control information including a first region, a second region, and a third region,set the second region and the third region to have values in a first specific combination when notifying, by using the first region, the second communication terminal of a first allocation result of a first wireless resource allocated to communication between the base station and the second communication terminal, andset the second region and the third region to have values in a second specific combination different from the first specific combination when notifying, by using the first region, the second communication terminal of a second allocation result of a second wireless resource allocated to direct communication between the second communication terminal and the first communication terminal, and the second communication terminal is configured to:
detect the control information,communicate with the base station in accordance with the first allocation result indicated in the first region when having determined that the second region and the third region of the detected control information have values in the first specific combination, anddirectly communicate with the first communication terminal in accordance with the second allocation result indicated in the first region when having determined that the second region and the third region of the detected control information have values in the second specific combination.
