摘要： A method for transmitting control data on a downlink and/or uplink channel in a base station and/or mobile station in a mobile communication system. In one embodiment, the base station determines whether there is downlink channel data to transmit to a mobile station. If there is no data to be transmitted over the downlink channel for a predetermined time period, the base station drives a random gating position selector to determine a random gating slot position, gates on the control data at the determined slot position, and gates off the control data at other slot positions. The random position selector determines the gating slot position by calculating a value x by multiplying a system frame number (SFN) of a received signal by a specific integer; selecting n bits starting from a position which is at an x-chip distance from the start point of a scrambling code, which has a period equal to one frame, before a plurality of gating durations used in generating a downlink signal; and determining a gating slot position of a corresponding gating slot group by performing a modulo operation on the selected n bits, where the module operation is by the number of slots in a gating slot group.

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： 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.
