Abstract:
PURPOSE: A channel allocating system and method thereof are provided to request channel allocation about a plurality of related traffic streams by using one message. CONSTITUTION: A communication unit(120) transceives messages for channel allocation and channel release with a channel response device. A correlation confirmation unit(112) checks correlation of traffic streams which receives channel allocation. The correlation confirmation unit confirms whether the traffic streams are related or not. An allocation requesting unit(114) generates a channel requesting message requesting a channel allocation about related traffic streams. The allocation requesting unit transmits the channel allocation request message to the channel responding device through the communication unit.

PURPOSE: A paging method in the wireless telecommunications system is provided to transmit the paging information to the terminal receiving a MBS(Multicast/Broadcast Service) from a base station. CONSTITUTION: A base station confirms whether the terminal receives MBS or not(S510). In case the terminal receives MBS, the base station transmits the paging related information considering MBS to the terminal(S520). The paging related information considering MBS comprises the paging offset information and the paging cycle information. The paging pre-defined option information and the paging cycle information are set so that the frame, in which the MBS burst assignment information, is accord with the frame in which the paging message can be transmitted.

PURPOSE: A frame generation/transmission method and an apparatus for wireless communication, a synchronization estimation method for wireless communication are provided to reduce the complexity of a receiving apparatus by using a preamble. CONSTITUTION: In a frame generation/transmission method and an apparatus for wireless communication, a synchronization estimation method for wireless communication, a correction sequence is generated by using a first base sequence for estimating synchronization(S201). A preamble is generated by allocating a first base sequence and a correction sequence to the frequency domain of a first time period(S203). The correction sequence includes a complex conjugate sequence of the first base sequence or a sequence which has different sign bit from the first base sequence. A step of generating the preamble includes a step of alternately assigning the alignment of the first base sequence and correction sequence to a subcarrier.
