Abstract:
PURPOSE: An all serializability checking method in an instant update duplication technique using a messaging order of a group communication is provided to reduce an unnecessary message transmission overhead and a withdrawal transaction overhead by performing a global serializability checking before broadcasting an update calculation message. CONSTITUTION: A transmission node transmits an MSN(Message Serial Number) request message to a group communication managing node(S500). The group communication managing node searches an update information table for every dr to check whether a dr has not been processed yet(S502). If there is a dr to be processed, the group communication managing node reads the dr(S504), and searches the dr from the update information table to obtain an MSN(dr) value of the corresponding dr(S506). If MSN(dr)=Φ(S508), the group communication managing node judges that the dr is valid. If MSN(dr) Φ(S508), the group communication managing node checks whether LastMSN(Ni) MSN(dr)(S510). If LastMSN(Ni) MSN, the group communication managing node transmits a withdrawal message to the MSN request node(S518). If every dr has been processed(S502), the group communication managing node allocates a new MSN with a Max MSN value increased by 1 to the node Ni(S512), stores every dw in the update information table(S514), and informs Ni about the newly allocated MSN and the completion of the all serializability checking result.

PURPOSE: An adaptive code bank managing method for allocating code channels in a mobile communication system and an apparatus therefor are provided to calculate the maximum number of allocable code channels according to wireless channel environments, and to adaptively vary the code bank by the size of communication traffic, so as to improve efficiency in communication channel use. CONSTITUTION: If a request for using code channels is generated, a channel number adjustor of a code bank management unit calculates the number of necessary code channels(S100,S110). The channel number adjustor calculates a link gain between a mobile station and a base station, on the basis of power amount allocated to all currently used code channels, total noise and interference amount, and SIR(Signal-to-Interference Rate)(S120,S130). The channel number adjustor calculates the number of additionally allocable code channels(S140). The channel number adjustor calculates the size of a code bank(S150). A channel allocator compares the number of necessary codes with the number of available channel codes(S160). If the number of necessary codes is larger, the channel allocator declares the failure of code channel allocation(S170). And if the number of necessary codes is smaller, the channel allocator allocates code channels(S180).
Abstract:
PURPOSE: A multiuser interference cancellation receiver for a TDD-CDMA(Time Division Duplex-Code Division Multiple Access) system and a method for controlling the interference cancellation are provided to perform interference cancellation for signals having high power values even when differences of signal power values are wide among users, so as to minimize errors in the detection of user signals having low signal power values. CONSTITUTION: A data extractor(100) extracts data from received signals and outputs the extracted data. A signal delay part(200) delays the signals outputted from the data extractor(100) during a predetermined time, and outputs the delayed signals. An interference cancellation selection part(300) extracts midamble signal channels from received original signals, to select and output users of the subject of the first interference cancellation. The first step interference cancellation block(400) receives data of the received signals from the data extractor(100), to perform the first parallel interference cancellation for the selected users of the first interference cancellation subject and output reproduction signals. And the second step interference cancellation block(500) receives data of the received signals delayed during the predetermined time and outputted from the signal delay part(200), to perform the second parallel interference cancellation using the first reproduction signals outputted from the first step interference cancellation block(400).
