A user equipment (UE), a device to device (D2D) UE, a backhaul device and a positioning method thereof are provided. The D2D UE measures an uplink reference signal transmitted from the UE and generates an uplink measurement report message according to the measured uplink reference signal. The backhaul device receives the uplink measurement report message and determines location information on at least one of the UE and D2D UE based on the uplink measurement report message.

User equipment, device to device user equipment, backhaul device and positioning method thereof

A MIMO network system and an interference eliminating method thereof are provided. MIMO network system includes a first mobile station and a base station. The base station has a plurality of antennas which are used for transmitting data to the first mobile station and receiving data from a second mobile station at the same time. The first mobile station determines an interference quality value according to a signal from the second mobile station and transmits the interference quality value to the base station. The base station determines a first receiving performance of the first mobile station according to the interference quality value and adjusts an antenna setting of the antennas according to the first receiving performance.

MIMO network system and interference eliminating method thereof

A small cell, a macro cell and a transmission assist method are provided. The small cell includes a transceiver and a processor. The processor generates a radio link failure (RLF) indication message when determining that an RLF count in a licensed band between the small cell and a user equipment reaches a threshold. The transceiver transmits the RLF indication message to the macro cell, and receives a modification request message from the macro cell. The modification message includes resource configuration information, and the resource configuration information indicates an unlicensed band radio resource of an unlicensed band. After confirming via the transceiver that the unlicensed band radio resource is available for data transmission with the user equipment, the processor generates a modification request acknowledge message, and transmits the modification request acknowledge message to the macro cell via the transceiver.
