  • Patent number: 9414253
    Abstract: A method of discarding logged measurements in a wireless communication system is provided. A user equipment in a Radio Resource Control (RRC) connected mode receives a Minimization of Drive Tests (MDT) configuration from a base station and starts a validity timer upon receiving the MDT configuration. The user equipment in an RRC idle mode logs measurements based on the MDT configuration to collect logged measurements while the validity timer is running. When the validity timer is expired, the user equipment discards the MDT configuration and starts a conservation timer. When the conservation timer is expired, the logged measurements are discarded.

  • Publication number: 20160205581
    Abstract: A user equipment (UE) and method are provided for transmitting an in-device coexistence (IDC) indication message in a wireless communication system. The UE receives a configuration message including an IDC indication from a base station. The UE transmits an IDC indication message to the base station if the UE determines that the IDC indication contains specific information. The specific information comprises an activation bit. The presence of the activation bit in the configuration message represents permission for the UE to transmit the IDC indication message. The IDC indication message includes frequency division multiplexing (FDM) assistant information. The FDM assistant information includes information on an unusable frequency in which interference from a long-term evolution (LTE) module in the UE to other coexisting technology modules in the UE or interference from other coexisting technology modules in the UE to the LTE module in the UE is expected.

  • Publication number: 20160173355
    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.

  • Patent number: 9338815
    Abstract: A method is described for a device to re-establish a connection with a Donor evolved Node B (DeNB). The device communicates with the DeNB via a Un interface using a subframe for the device only. The device detects a problem associated with the Un interface, and performs a radio resource control (RRC) re-establishment procedure to re-establish a RRC connection between the device and the DeNB after detecting the problem associated with the Un interface. The device starts a timer upon detecting the problem associated with the Un interface, and releases a restriction of using the subframe for the device only, if the timer expires. An occurrence of the problem associated with the Un interface is determined in response to receiving consecutive out-of-sync indications.
