  • Method for processing NDI in random access procedure and a method for transmitting and receiving a signal using the same
    Patent number: 9661618
    Abstract: A method for a user equipment (UE) to receive a downlink signal. The UE receives a first downlink assignment including a first new data indicator (NDI) from a base station. The UE compares the first NDI to a second NDI and, based on a result of the comparison, determines whether the first NDI has been toggled. The UE receives the downlink signal and processes the received downlink signal based on whether the first NDI has been determined to be toggled. Furthermore, the second NDI is included in a second downlink assignment that was previously received from the base station and was not identified by a temporary cell identifier.

  • METHOD FOR PROCESSING RADIO PROTOCOL IN MOBILE TELECOMMUNICATIONS SYSTEM AND TRANSMITTER OF MOBILE TELECOMMUNICATIONS
    Publication number: 20170134982
    Abstract: An apparatus and method for performing procedures (protocols) of a PDCP (Packet Data Convergence Protocol) layer and an RLC (radio layer in an E-UMTS (Evolved Universal Mobile Telecommunications System) which has evolved from UMTS, among radio protocols of a mobile communication system. The PDCP layer performs ciphering on data (i.e., PDCP SDU) received from an upper layer, generates an indicator discriminating ciphered data and non-ciphered data (i.e., an ROHC feedback packet directly generated by the PDCP layer), and transmits the same to a lower layer (i.e., MAC layer). A PDCP SN (Sequence Number) is defined as an algorithm for ciphering the data in the PDCP layer to perform ciphering in the PDCP layer.

  • Method for a user terminal to random access a carrier aggregation mobile communication system
    Patent number: 9629184
    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: 9629009
    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.
