Abstract: A base station resets a wireless signal processing time depending on the processing capability of a terminal, and determines the transmission position of a feedback signal for a data packet using the reset wireless signal processing time and transmits the same to the terminal. If the feedback signal indicates the success of reception of the data packet, the data packet can be processed using the reset wireless signal processing time, and the wireless signal processing time can be reset to a smaller value.

Abstract: The present invention relates to a scheduling apparatus and a method thereof in an HPi system. A scheduling algorithm is applied appropriate to a characteristic of each multimedia service (e.g., real-time service, non real-time service, best-effort service, etc.) and a transmission order of the IP packets transmitted from a network is determined such that a transmit wait queue is generated. Radio resource allocation is performed in accordance with the order of the data items queued in the transmit wait queue, the size of transmittable data is determined such that a PDU is generated. In addition, frame data formed of bursts of PDUs is generated and transmitted to a physical layer. Therefore, a scheduling algorithm can be applied appropriate to characteristics of each multimedia service. In addition, packet scheduling is performed in two steps in order to schedule traffic corresponding to radio frames such that packets can be efficiently processed.

Abstract: Disclosed are a base station and a mobile station which communicate with each other using a frame comprising one or more downlink subframes and one or more uplink subframes. The base station transmits a data burst in a subframe corresponding to a downlink subframe index of a frame corresponding to a first frame index. The mobile station transmits a feedback for the data burst in a subframe corresponding to an uplink subframe index of a frame corresponding to a second frame index. The second frame index and the uplink subframe index are determined by a parameter value. The parameter value is determined by a difference between radio signal processing time and the number of the one or more uplink subframes.

Abstract: Provided is a paging method in a broadband wireless communication system. In order to provide a paging service to a terminal in a wireless communication system in which a macrocell base station and a femtocell base station coexist, the femtocell base station receives a deregistration request message from the terminal, and checks whether the femtocell base station can provide a paging service to the terminal. When failing to provide a paging service to the terminal, the femtocell base station receives paging service information from a paging controller, includes paging service information in a deregistration confirmation message, and transmits it to the terminal, and the macrocell base station provides a paging service to the terminal.
