摘要： Disclosed is a method for efficiently transmitting and receiving control information messages necessary for a Multimedia Broadcast/Multicast Service (MBMS) provided in a mobile communication system. The method includes setting information elements for the control information messages to reduce unnecessary signaling overhead during the transmission of the control information. The method prevents a user equipment (UE) from performing duplicate reception on the control information, thereby reducing power consumption of a battery.

摘要： A notification method for informing a UE of an existence or absence of control information for an MBMS in a mobile communication system supporting the MBMS. In the method, the UE receives a notification indicator channel independently reporting the existence of the control information for the MBMS, confirms at least one notification indicator of the notification indicator channel, thereby confirming the existence of the control information relating to the requested MBMS. Further, a method is proposed, which can minimize an alarm due to other MBMSs.

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 common packet channel assignment method and device in a CDMA (Code Division Multiple Access) communication system is disclosed. The method comprises transmitting an access preamble signal having channel information which is used to access a base station, and then receiving an; access preamble acquisition indicator signal from the base station in response to the access preamble signal. A collision detection preamble for detecting a collision is transmitted in response to the received access preamble acquisition indicator signal. A first signal indicating acquisition of the collision detection preamble and a second signal indicating channel assignment are received, both of which the base station has transmitted in response to the collision acquisition signal. Upon receipt of the first signal, a common packet channel is assigned according to information designated by the second signal.
