    摘要: A communication system performing a coordinated multipoint transmission is provided. A mobile station may measure expected channel quality information when an interference of a serving base station does not exist. The serving base station may determine whether a neighbor base station and the serving base station are eligible to perform the coordinated multipoint transmission. The serving base station may determine whether the neighbor base station and the serving base station are eligible to perform the coordinated multipoint transmission using a criterion associated with an evaluation of an increase in a transmission rate of the mobile station.

    摘要: A multi-cell communication system comprises at least a first base station and first terminal and a second base station and second terminal. When the first and second base stations need to perform interference control, the first terminal may relay a message related to the interference control between the first base station and the second base station. That is, the first terminal may transfer a message related to the interference control from the first base station to the second base station, and a message related to the interference control from the second base station to the first base station. As such, the first base station and the second base station can transmit/receive messages that are for performing interference control via the first terminal.

    摘要: Provided are a system and method of transmitting an Aggregated Media Access Control (MAC) Protocol Data Unit (A-MPDU) in a Wireless Local Area Network (WLAN) system. A MAC layer divides service data transferred from an upper layer into a plurality of MPDUs, forms a single transmission frame including the sequentially arranged MPDUs, delimiter information for distinguishing each of the MPDUs, and ACK request information for requesting for a reception result of the MPDUs, and transmits the formed transmission frame to a recipient. Accordingly, service coverage is extended, and a transmission delay is minimized, resulting in improved service efficiency.

    摘要: A precoding method for a femtocell or a picocell and a communication system using the same is provided. The communication system may include a small base station that is able to implement a protection mode to protect a neighbor terminal from an interference regardless of whether a neighbor base station is performing a process to protect the neighbor terminal from the interference. Also, the small base station may use at least one process scheme appropriate for a current environment among various process schemes, thereby effectively protecting the neighbor terminal from the interference.
