Abstract: A mobile station receives a MIMO feedback mode bitmap and information on a MIMO feedback period. The mobile station estimates channel information corresponding to at least one MIMO feedback mode indicated by the MIMO feedback mode bitmap. The mobile station generates a MIMO feedback including the MIMO feedback mode bitmap and the channel information corresponding to the at least one MIMO feedback mode indicated by the MIMO feedback mode bitmap. The mobile station transmits the MIMO feedback at the advent of the MIMO feedback period.

Abstract: PURPOSE: A communication method is provided to embody high-speed packet transmission by preventing packet transmit delay. CONSTITUTION: A BS(Base Station) transfers DL(DownLink) resource allocation information to an MS(Mobile Station) in the I-numbered sub frame of an i-numbered frame(S110). The BS starts to transmit DL data burst such as a sub packet with DL resources allocated according to the DL resource allocation information in the m-numbered sub frame of the i-numbered frame(S130). The MS decodes the received DL data burst. According to the success of decoding, the MS transmits ACK or NACK feedback to the BS(S150).

Abstract: A packet scheduler and a packet scheduling method are provided to satisfy a fair transmission rate of system resources and wired/wireless resources of radio traffic by inducing a fair traffic jacket transmission. An RLC(Radio Link Control) packet scheduler of an RLC layer checks whether a bearer is a real time bearer or a non-real time bearer(S100). If the bearer is a real time bearer, the RLC packet scheduler calculates a virtual scheduling time(S200). In the case of the non-real time bearer, the RLC packet scheduler calculates the virtual scheduling time by using another mathematic formula(S300). The RLC packet scheduler preferentially transmits a packet of a bearer having the largest virtual scheduling time to a MAC(Medium Access Control) layer by using the calculated virtual scheduling time(S400).
