A method for receiving a packet by a terminal in a mobile communication system including a base station providing a packet, and a terminal that discontinuously receives a packet from the base station in Discontinuous Reception (DRX) cycles each having an active period and a sleep period. The packet reception method includes receiving, from the base station, configuration information for a DRX service, including a DRX cycle length; setting, as a starting point of the DRX cycle, a point at which a first packet is received from the base station; receiving a packet from the base station for an active period at the beginning of the starting point; and transitioning to a sleep period and waiting for a next active period.

An apparatus and method for signalling sub-frame allocation pattern. The present invention is provided a method of signalling a sub-frame allocation pattern to apparatus (e.g. UE) adapted to receive wirelessly and extract data from a radio signal (e.g. a signal carrying MBMS channels) comprising a series of radio frames, each radio frame comprising a plurality of sub-frames for carrying data, the sub-frame allocation pattern indicating the position of at least each sub-frame, in the series of radio frames, allocated to carry data of one respective data channel (e.g. one MCH) of a plurality of data channels. The method comprises providing the apparatus with an indication of a set of sub-frames (e.g. a common sub-frame pool), in the series of radio frames, reserved for carrying data of said plurality of data channels (e.g. the MCHs), and providing the apparatus with an indication of a at least one sub-set (e.g. a sub-set of the common pool allocated to a particular MCH) of the set of sub-frames allocated to carry data of a respective one of said data channels.

Disclosed is a method and an apparatus for reordering received packets in a mobile telecommunication system supporting HARQ so that the problem of order change is solved. The method includes receiving from a receiving-side HARQ entity an input of a packet and processing time spent by the packet going through an HARQ operation; determining if a gap corresponding to at least one missing packet among received packets is detected based on the input packet belonging to the received packets and, when the gap is detected, waiting for the missing packet belonging to the gap to be received for a period of time obtained by subtracting the processing time from a predetermined maximum waiting value; and outputting the received packets to an upper layer in an order when the missing packet belonging to the gap fails to be received before the expiration of the period of time.

Provided is a method of broadcasting in a telecommunications network in a segmentation/re-assembly mode, wherein segmentation and/or re-assembly is performed based on ordering information or sequence number information generated from a transmission schedule.
摘要:
A method and apparatus for performing measurement by a User Equipment (UE) in a mobile communication system are provided. The UE has a Discontinuous Reception (DRX) mode for discontinuously receiving data and a continuous reception mode for continuously receiving data. The mobile communication system also has a serving cell where the UE is located, and a neighboring cell located near the serving cell. Signal strength of the serving cell is measured according to a period of the DRX mode. The signal strength measurement is continuously performed on the serving cell and the neighboring cell, if the measured signal strength of the serving cell is less than or equal to a particular threshold. The continuous signal strength measurement is stopped and signal strength of the serving cell is measured according to the period of the DRX mode, if the continuously measured signal strength of the serving cell is greater than the particular threshold.

A method and apparatus for establishing an RRC connection are provided, in which a UE compares the strength of a signal received from a serving cell with a threshold, upon receipt of a request for RRC connection establishment, transmits an RRC connection request message to a RAN, measures the strengths of signals from neighbor cells during a first time period and monitors a downlink channel of the serving cell to receive a response message for the RRC connection request message during a second time period, if the signal strength of the serving cell is less than the threshold, and receives the response message from the RAN on the downlink channel.

Disclosed is an apparatus and a method for radio connection setup in a mobile communication system. In the method, a UE reports mobility information to a network, and the network performs according to the mobility information of the UE. Therefore, it is possible to reduce complexity of the UE and reduce the waste in power consumption thereof, and reduce the signaling overhead of the network, thereby achieving efficient use of resources.
摘要:
A method and apparatus for transmitting a packet in a mobile communication system. A transmitting side allocates a short sequence number for an initial transmission packet using some bits among bits of a predetermined length for expressing a sequence number of the packet, and sets a first flag indicating use of the short sequence number. The transmitting side inserts the short sequence number and the first flag into the packet, and transmits the packet to a receiving side.
