摘要： A wireless communication method for efficiently managing a bandwidth request of a terminal and an allocation procedure and a system thereof are provided to operate an RS system in two modes in consideration of a case that an MS directly transmits a BR code to an MR-BS, thereby improving system performance while satisfying existing standards. It is monitored whether an uplink map information element corresponding to a BR(Bandwidth Request) code of an MS(Mobile Station) is received from an MR(Mobile Relay)-BS(Base Station)(S402). The RS monitors an uplink burst having a bandwidth that the MS requests is transmitted from the MR-BS based on the uplink map information element. Data that the MS transmits is relayed to a band allocated by the uplink burst from the MR-BS.

摘要： PURPOSE: A clock group monitoring and selecting circuit is provided to simultaneously receive two clock groups from external clock boards, and to monitor whether the two clock groups are normal, then to supply a normal clock group to a modem, thereby stabilizing clocks distributed to the system modem. CONSTITUTION: The first and second clock receivers(110,120) receive the first and second clock groups consisting of many clocks from external clock boards. The first and second clock monitors(210,220) check states of the received first and second clock groups, respectively, and output result signals. A clock selector(300) selects the received first and second clock groups according to outputted state monitor information of the first and second clock groups, and outputs the selected clock groups. The first and second clock monitors(210,220) include retriggerable monostable multi-vibrators as many as the number of clocks included in the first and second clock groups. The retriggerable monostable multi-vibrators monitor the clock groups, and generate high-level signals if the clock groups are not inputted, then generate low-level signals if the groups are inputted.

If the received traffic frames arrive faster than the predetermined window, a traffic storage(220) stores the traffic frames. A traffic processor and transmitter(230) processes the stored traffic frames according to a confirmed result, or processes the received traffic frames, transmits the frames to mobile stations(300-300n), and informs the THM(110) of information related to arrival time of the traffic frames.
