Abstract: PURPOSE: A device of measuring a signal for handover in a mobile communication system is provided to change resources such as time slots and codes used in a UE(User Equipment) for inter frequency or inter-RAT(Radio Access Technologies) measurement in a section of measuring inter frequency or inter-RAT, thereby using sufficient length of the inter frequency or inter-RAT measuring section. CONSTITUTION: A frame is composed of the first sub frame(801) and the second sub frame(802). When inter frequency or inter-RAT measurement is necessary in the one frame, measurement sections(803,804,805) are supplied. The measurement section(804) has at least 5 consecutive time slots including transmission sections of a DwPTS(Downlink Pilot Time Slot), a GP(Guard Period), and a UpPTS(Uplink Pilot Time Slot) after a time slot(811), and averagely has a longer measurement section while UEs are located in optional time slots of uplink/downlink transmission channels. When considering consecutive frames, the measurement sections(803,805) use two time slots before a time slot(810), including 3 time slots after a downlink time slot(813) and transmission sections of the DwPTS, the GP, and the UpPTS, and have longer measurement sections while the UEs are located in the optional time slots of the uplink/downlink transmission channels.

Abstract: PURPOSE: A method and an apparatus for synchronizing a base station in a mobile communication system are provided to perform the synchronization of the base station by acquiring the system time difference between a primary base station and a secondary base station through a wireless link and adjusting a system time of the secondary base station. CONSTITUTION: A secondary base station judges a sign of a system time difference(641). If the sign of the system time difference is a positive number, the secondary base station moves its system time forward by a time(T track) because a system clock of the secondary base station is slower than a system clock of a primary base station(643,645,647). If the sign of the system time difference is a negative number, the secondary base station moves its system time backward by the time(T track) because the system clock of the secondary base station is faster than the system clock of the primary base station(644,646,648).

Abstract: PURPOSE: A method for resetting a MAC-hs(Medium Access Control-high speed) layer entity in an HSDPA(High Speed Downlink Packet Access) communication system is provided to reset an object RLC(Radio Link Control) and simultaneously reset a MAC-hs layer when an RLC reset is performed by an error generation of a frame protocol. CONSTITUTION: A transmission-side RLC transmits and receives data with a reception-side RLC in an acknowledged data transfer ready state, and checks whether an error is generated(1201,1202). The transmission-side RLC checks over whether a protocol error is generated(1203). If the protocol error is generated, the transmission-side RLC transmits a frame protocol message for instructing a MAC-hs reset according to the reset generation of the transmission-side RLC to a transmission-side MAC-hs(1204). The transmission-side RLC transits the transmission-side RLC's own state into a reset pending state, and transmits an RLC reset PDU(Protocol Data Unit) for indicating reset information to the reception-side RLC(1205).

Abstract: PURPOSE: An apparatus and a method for informing whether a signal received in a UE(User Equipment) exists in a CDMA(Code Division Multiple Access) mobile communication system are provided to inform by using a dedicated control channel whether a signal of a common control channel including information necessary for receiving an HS-DSCH(High Speed-Downlink Shared Channel) exists or not. CONSTITUTION: A CPICH(Common Pilot Channel) estimator(3001) performs a channel estimation per every slot or every frame. A separator(3002) receives a pilot and an indicator from a cell 1 which transmits an HS-DSCH, and separates the pilot and the indicator. A signal decider(3003) receives an HS-DSCH indicator, analyzes the HS-DSCH indicator, multiplies a sign of the HS-DSCH indicator by 1 to invert the sign of the HS-DSCH indicator when the sign of the HS-DSCH indicator is different from a sign of the pilot, and transmits the HS-DSCH indicator to a switch(3004). In case that the sign of the HS-DSCH indicator is identical to the sign of the pilot, the signal decider(3003) immediately transmits the HS-DSCH indicator to the switch(3004). The switch(3004) transmits or does not transmits the HS-DSCH indicator modified by the signal decider(3003) on the basis of the CHICH estimation value received from the CPICH estimator(3001). An SIRest generator(3005) generates an SIRest using pilot bits received from the cell 1 and a cell 2 which does not transmit the HS-DSCH.

Abstract: PURPOSE: A mobile communication device including an antenna array and a method therefor are provided to minimize the influence of fading, interference, and noise by feeding back information corresponding to the characteristic of a time-space channel according to antennas which exist in a base station. CONSTITUTION: Mobile stations(20,22,24) measure a downward characteristic of an antenna-classified channel from a signal transmitted from a base station(10), and determine long information and short information corresponding to a correlation characteristic of the antenna-classified channel from the measured downward characteristic. The mobile stations(20,22,24) convert determined long and short information into a feedback signal, and transmits the feedback signal to the base station(10). The base station(10) receives the feedback signal, extracts a plurality of weight values from long and short information recovered from the received feedback signal, and multiplies a multiplexed result of a dedicated physical channel signal by a plurality of weight values. The base station(10) adds pilot channel signals to the multiplied results, and transmits the added results to the mobile stations(20,22,24) through an antenna array.

If a current mode is a ring-back tone download mode, the control unit receives a ring-back tone from a database through the transmission base station and stores the received ring-back tone in a ring-back tone storing unit(420). If the RF signal is the general ring-back tone, the control unit controls the ring-back tone storing unit and transmits a ring-back tone previously selected by a user through a ring-back tone transmitting unit(430).

Abstract: PURPOSE: A communication execution apparatus and method for the transmit antenna array of a PDSCH(Physical Downlink Shared CHannel) in a mobile telecommunication system is provided so that a UE(User Element) can control a PDSCH transmit antenna array at a SHO(Soft HandOver) area. CONSTITUTION: If radio signals from UEs are received through the first antenna(859) and the second antenna(860), the received signals are outputted to a DEMUX(852). The DEMUX(852) detects FBI(FeedBack Information) from the reverse DPCCH(Dedicated Physical Control CHannel) signals of the radio signals and outputs it to a weight generator(851). The weight generator(851) combines input bits using the FBI outputted from the DEMUX(852), generates weights(w11,w12,w21,w22), and outputs the generated weights to multipliers(855,856,863,864) respectively. Meanwhile, a DPDCH(Dedicated Physical Data CHannel) signal and a DPCCH signal are inputted to a MUX(853). The MUX(853) multiplexes the inputted signals, converts them into DPCH(Dedicated Physical control CHannel) signals, and outputs the DPCH signals to a multiplier(854). The multiplier(854) multiplies the DPCH signals by a spreading and scrambling code of node B1 and outputs them to the multipliers(855,856) respectively. The multiplier(855) multiplies an output signal of the multiplier(854) by the weight(w11) outputted from the weight generator(851) and outputs it to an adder(857). The multiplier(856) multiplies an output signal of the multiplier(854) by the weight(w12) outputted from the weight generator(851) and outputs it to an adder(858).
