摘要： Disclosed are a method, terminal, and base station for cooperative communication. A cooperative communication relationship between the terminals is established by the base station, wherein the cooperative communication relationship is that the terminals can directly transmit service data to each other by using uplink frequency spectrum in a communications system, that is, the terminals, which are in the cooperative communication relationship established by the base station, can directly transmit terminal-to-terminal service data to each other by using the uplink frequency spectrum, without through the base station. In this way, the base station effectively utilizes an idle frequency band in the uplink frequency spectrum to transmit the service data between the terminals, thereby improving effective utilization of the uplink frequency spectrum.

摘要： Provided are a multi-antenna system and a mobile terminal. A dual band is achieved through PIFA antennas on dielectric substrates and grooves on radiation patches of the antennas. The isolation degree between the antennas is improved by arranging an isolated branch knot between the antennas. The isolation degree between the antennas on the two medium substrates is further improved through the two independent medium substrates and a metal ground. In addition, the PIFA antennas are used, so that the multi-antenna system and the mobile terminal can increase the number of antennas in a limited space as many as possible.
