  • METHOD FOR A USER TERMINAL TO RANDOM ACCESS A CARRIER AGGREGATION MOBILE COMMUNICATION SYSTEM
    Publication number: 20170181196
    Abstract: A method for random access to a base station by a user equipment (UE) in a mobile communication system using carrier aggregation in which communication is conducted over a plurality of component carriers, and a terminal for the method are disclosed. When the UE performs a contention-based random access procedure in the mobile communication system to which CA technology is applied, the UE considers an uplink grant signal as a contention resolution message when receiving the uplink grant signal from a eNB only when the uplink grant signal is received through a downlink CC corresponding to an uplink CC used to transmit a random access preamble or a third message, to thereby prevent contention resolution from being erroneously ended.

  • Method and apparatus for measuring a packet throughput in wireless communication system
    Patent number: 9680725
    Abstract: A method and apparatus of measuring a packet throughput in a wireless communication system are provided. When determining a reference time for estimating packet throughput, a receiver determines the time that a data burst starts or ends in order to estimate the packet throughput considering a change in the data burst of the transmitter buffer. A measurement period is defined through the determined start time and end time of the data burst, and packet throughput is measured considering the total amount of the received data burst. The throughput of packet data may be estimated by each base station based on the same standard rule, so that the measured packet throughput values may be reliable, thus allowing the operator to make use of it as a parameter for MDT.
