Abstract:
A method of transmitting and receiving control information in a wireless communication system is disclosed. The method of receiving control information related to a specific point-to-multipoint service in a user equipment of a wireless communication system comprises receiving a notification message including indication information and an identifier identifying the point-to-multipoint service from a network, the indication information indicating at least one downlink channel related to the specific point-to-multipoint service among a plurality of downlink channels established for transmission of control information for at least one or more point-to-multipoint service, and receiving at least one downlink channel indicated by the indication information.
Abstract:
A timer for processing data blocks is proposed for a receiver of a mobile communications system. If the timer is not running, the timer is started based a data block. The data block has a sequence number higher than a sequence number of another data block that was first expected to be received. If the timer is stopped or expires, the timer is based on a highest sequence number of a data block among data blocks that cannot be delivered to a higher entity. The timer can be used to prevent a stall condition in mobile communications.
Abstract:
A method in which a user equipment processes data in a wireless mobile communication system is provided. The method includes the steps of receiving a first data block from an upper layer, transferring a second data block including the first data block to a lower layer at a particular protocol layer, discarding the first and second data blocks present in the particular protocol layer if a certain period of time has passed, and transferring information associated with the discard of the second data block to the lower layer.
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:
According to one aspect of the present invention, a reporting method in a wireless communication system is provided. The method comprises: determining a service state; controlling positioning for acquiring position information based on the service state; acquiring information on the position of a terminal according to the positioning mode determined by said controlling; and reporting the acquired position information to a network.
Abstract:
A method and apparatus of reporting logged measurements in a wireless communication system is provided. A user equipment in a Radio Resource Control (RRC) connected mode receives 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.
Abstract:
A method of receiving packets at a network in a mobile communication system. Including receiving a first packet from a user equipment; and receiving a second packet from the user equipment regardless of a reception status for the first packet, if control information for the second packet is transmitted to the user equipment.
Abstract:
There is provided a method for enabling a user equipment (UE) to transition between a non-discontinuous reception (Non-DRX) level and at least one discontinuous reception (DRX) level. The UE in a DRX level wakes up periodically to monitor a scheduling channel. The method includes receiving a DRX indicator in a Non-DRX level with continuously monitoring the scheduling channel and transitioning from the Non-DRX level to a DRX level indicated by the DRX indicator. The UE can transition between multiple DRX levels by an explicit command/signaling.
Abstract:
A method for operating a relay node in a wireless communication system. The method includes communicating, by the relay node, with a base station using a specific subframe for the relay node only; detecting, by the relay node, a problem with a connection between the relay node and the base station; starting, by the relay node, a timer upon detecting the problem with the connection between the relay node and the base station; and releasing, by the relay node, a restriction of using the specific subframe for the relay node only, if the started timer expires. The problem with the connection between the relay node and the base station is associated with a radio link failure.
Abstract:
A method for a user equipment (UE) to receive a downlink signal, the method including receiving a first downlink control channel identified by a temporary cell identifier (Temporary C-RNTI) from a base station, the first downlink control channel including a first downlink assignment signal having a new data indicator (NDI) with a first value; receiving a second downlink control channel identified by a cell identifier (C-RNTI) from the base station, the second downlink control channel including a second downlink assignment signal having the NDI with a second value; and determining if the NDI has been toggled compared to the NDI previously received from the base station. Further, the UE ignores the NDI with the first value received through the first downlink control channel identified by the temporary cell identifier (Temporary C-RNTI). The method also includes receiving the downlink signal based on the determining.
