摘要： A method is disclosed for determining by a UTRAN a persistence value having a value between 0 and 1 for adjusting a number of access preambles from a plurality of UEs requiring assignment of a common packet channel (CPCH). The method includes the steps of counting a number of the access preambles detected in an access preamble period having a predetermined period; and determining the persistence value based on the number of counted access preambles. The persistence value is determined in a unit of transport format (TF), physical common packet channel (PCPCH), or CPCH set.

摘要： Disclosed is a method for indicating an end of transmitting data frames in order to enable a UTRAN (UMTS (Universal Mobile Telecommunications System) Terrestrial Radio Access Network) to assign a common packet channel to another user equipment (UE) in a UE for a CDMA mobile communication system. The UE requests assignment of any one of a number of common packet channels assignable in the UTRAN; the UE is assigned a common packet channel by the UTRAN in response to the to request; the UE sequentially transmits the data frames and their associated control frames over the assigned common packet channel; and the UE transmits at least one control frame, in an appointed field of which a given bit pattern appointed with the UTRAN is registered, in order to inform the UTRAN of an end of data transmission upon completing data transmission through the data frames.

摘要： Disclosed is a method for synchronizing a scrambling code in a CDMA communication system including a UTRAN (UMTS Terrestrial Radio Access Network) and a plurality of user equipments (UEs), using orthogonal codes for identifying the UEs and a single scrambling code for identifying the UTRAN by the UEs, and employing an uplink synchronous transmission scheme (USTS) where the UEs synchronize frames of uplink dedicated physical channels (DPCHs) using the single scrambling code. The UEs receive a reference signal including reference time information provided from the UTRAN and transmit a random access channel (RACH) based on the reference time. The UTRAN receives the random access channels from the UEs to measure a propagation delay time (PD) of each random access channel signal from the UEs, and transmits a transmission time adjustment value calculated using the measured propagation delay time and a time offset τDPCH,n between a transmission time point of the reference signal and a transmission time point of a downlink DPCH. Each UE determines a transmission time of the uplink DPCH by receiving the transmission time adjustment value, and scrambles a message with the orthogonal code and a scrambling code generated at the reference time, at the transmission time so determined as to transmit the message over the uplink DPCH.

摘要： Disclosed is a handover controlling method in an RNC connected to a first Node B and a second Node B in a mobile communication system where a USTS service occurs between the first Node B and a UE within a cell of the first Node B and the UE hands over when the UE is located in a handover area across the cell areas of the first Node B and the second Node B adjacent to the first Node B. The method comprises determining whether the handover for the UE is possible or not; transmitting handover information to the second Node B if the handover is possible; and transmitting a command to the UE through the first Node B, requesting the UE to hand over to the second Node B if the UE receives a response message indicating that the handover is possible from the second Node B.

摘要： Disclosed is an apparatus for encoding k consecutive inputs indicating a TFCI (Transport Format Combination Indicator) of each of successively transmitted frames into a sequence of m symbols in an NB-TDD (Narrowband-Time Division Duplex) mobile communication system. An encoder encodes the k input bits into a sequence of at least 2n symbols where 2n>m, using an extended Reed-Muller code from a Kasami sequence. A puncturer performs puncturing on the sequence of 2n symbols from the encoder so as to output a sequence of m symbols.
