    摘要: Disclosed is an uplink random access procedure in an NB-TDD (Narrow Band Time Division Duplexing) system. To achieve an acknowledgement for data transmission from a UTRAN (UMTS Terrestrial Radio Access Network), a UE selects one of a plurality of sync codes by which the UTRAN identifies UEs that request data transmission and transmits the selected sync code in a time slot of a sub-frame to the UTRAN. Then, the UE receives the sync code information, information about the arrival time of the sync code, time update information indicating a variation in the transmission time of data, and power information indicating an adjustment to a power gain in the UE from the UTRAN on an FPACH (Fast Physical Access Channel). The UE transmits the data on a P-RACH (Physical Random Access Channel) mapped from the FPACH according to the time update information and the power information.

    摘要: A method for setting up signaling connection between an RNC and an SGSN in a mobile communication system is provided. Upon receiving a service request for a particular MBMS service from a particular UE, an RNC determines whether it is necessary to set up new signaling connection for the particular MBMS service, and sets up signaling connection with an SGSN according to the determination result. The SGSN, if it desires to stop the particular MBMS service, sends a service stop request to the RNC over the signaling connection set for the particular MBMS service. The RNC then instructs at least one UE providing the particular MBMS service to stop the particular MBMS service in response to the service stop request.

    摘要: An apparatus and method for defining non-scheduled data for autonomous transmission without Node B-controlled scheduling and notifying the non-scheduled data in a mobile communication system supporting an uplink packet data service are provided. An Radio Network Controller (RNC) includes in an Enhanced Uplink Dedicated CHannel (E-DCH) setup message minimum set information indicating whether each transmittable Media Access Control-data (MAC-d) flow can be transmitted without a scheduling command from a Node B.

    摘要: Disclosed is a method for measuring a propagation delay value of a frame transmitted by a UE (User Equipment) to a Node B in a TDD (Time Division Duplexing) mobile communication system. The UE acquires synchronization with the Node B based on a downlink pilot channel signal transmitted in a period of a downlink pilot time slot, and determines an estimated round trip delay value T1 by comparing transmission power of a physical common channel signal in a first time slot with reception power of the same signal. The UE receives a transmission point correcting value T2 through a forward physical access channel (FPACH) signal transmitted from the Node B in a period of one downlink time slot among the time slots, and transmits a physical random access channel (PRACH) message with the estimated round trip delay value T1 at a transmission point determined based on T2 and T1.

    摘要: A control message transmitting/receiving method in an MBMS-supporting mobile communication system. In the present invention, an RNC periodically transmits control messages related to MBMS RB setup to UEs. Thus, although a UE initially fails to receive an intended MBMS service, it can set up an MBMS RB by receiving a related retransmitted control message. Also, the RNC periodically provides information about ongoing MBMS services on a cell basis so that a UE can decide whether its requested MBMS service is in progress and request information required to set up an MBMS RB for the MBMS service to the RNC by individual signaling.
