    摘要: 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.

    摘要: The present invention relates to a resource request and a packet scheduling method for uplink traffic in a mobile communication system. For efficient scheduling of the uplink traffic, a base station and user equipment (UE) determines a scheduling method according to characteristics of the traffic when performing negotiation therebetween. The traffic may be classified into traffic that generating a fixed-size packet in a periodical time interval, traffic that generates a variable-size packet in a periodic time interval, and traffic that generates a variable-size packet in a random time interval. Therefore, the UE requests a resource in accordance with the characteristics of the traffic and the base station performs scheduling according to the characteristics of the traffic such that an optimal uplink packet scheduling can be achieved.
