Abstract:
A method for performing a logged measurement in wireless communication system is provided. The method includes receiving measurement configuration from a network, logging MDT (Minimization of Driving Tests) measurement, detecting whether a condition for state transition has occurred, performing state transition when the condition for state transition has occurred, and logging state transition information related to said state transition.
Abstract:
A method of moving a receiving window in a wireless mobile communication system, wherein the AM RLC of the transmitting side sends information of the last discarded SDU regardless of continuity of the discarded SDUs. The AM RLC of the receiving side checks whether all SDUs from the start point of the receiving window up to the last discarded SDU are successfully received, delivers the SDUs that are successfully received to an upper layer, and discard only those SDUs that are not successfully received.
Abstract:
A method of monitoring a control channel in a wireless communication system includes monitoring a physical down-link control channel (PDCCH) during a monitored duration, wherein the monitored duration is a part of a discontinuous reception (DRX) period, the DRX period specifying the periodic repetition of the monitored duration followed by a non-monitored duration. By monitoring a control channel during a DRX period, battery consumption of a user equipment can be reduced and an operation time of the user equipment can be increased.
Abstract:
A method of generating a data block for performing a polling procedure in a wireless communication system, a method of transmitting data and a method of performing a polling procedure are disclosed. A protocol layer performs the polling procedure for requesting a receiving side to transmit status report if there are no data to be transmitted to the receiving side in both a transmission buffer and a retransmission buffer. When determining whether there are no data to be transmitted to the receiving side in the retransmission buffer, it is preferable that a data block for which retransmission request information is not received from the receiving side is excluded.
Abstract:
A method of performing a Hybrid Automatic Repeat reQuest (HARQ) operation in a wireless communication system. The method according to one embodiment includes storing a data unit into at least one of a HARQ buffer among all HARQ buffers; and flushing all HARQ buffers when a timer expires. The timer is a time alignment timer (TAT) which is used to control how long a User Equipment (UE) is considered to have an uplink time that is aligned. The stored data unit is a Medium Access Control (MAC) Protocol Data Unit (PDU). The TAT is started when a time advance command (TAC) is received from a network.
Abstract:
A method of performing contention resolution associated with a random access procedure. The method according to one embodiment includes transmitting, by the mobile communication terminal, an uplink message containing a cell-radio network temporary identity (C-RNTI) and starting a contention resolution timer; receiving, by the mobile communication terminal, a physical downlink control channel (PDCCH) transmission; and considering, by the mobile communication terminal, a contention resolution successful and stopping the contention resolution timer if a specific condition is satisfied. The mobile communication terminal considers the contention resolution successful and stops the contention resolution timer if the PDCCH transmission is addressed to the C-RNTI and the random access procedure is initiated by a downlink (DL) data arrival. The mobile communication terminal considers the contention resolution successful and stops the contention resolution timer if the PDCCH transmission is addressed to the C-RNTI and contains an uplink (UL) grant.
Abstract:
A method and apparatus of reporting logged measurements of an user equipment in a wireless communication system is provided. The user equipment in a Radio Resource Control (RRC) connected mode receives from a base station a Minimization of Drive Tests (MDT) configuration. The user equipment transitions from the RRC connected mode to an RRC idle mode and logs measurements based on the MDT configuration. The user equipment transmits to the base station a logging indicator indicating an availability of the logged measurement.
Abstract:
A method of receiving a service from a network in a mobile communication system in accordance with the present invention comprises receiving static scheduling information from a network, the static scheduling information including information on radio resources associated with combining reception, receiving dynamic scheduling information from the network, the dynamic scheduling information including control information for receiving the service, and receiving the service by combining downlink shared channels transmitted from a plurality of cells based on the static scheduling information and the dynamic scheduling information.
