說明書
In the CQI transmission type of transmitting both a WB CQI and an SB CQI, the WB CQI is transmitted in the first CQI transmission subframe and an SB CQI of the better SB state of SB0 and SB1 in BP0 is transmitted in the next CQI transmission subframe together with and an index of the corresponding SB (e.g. Subband Selection Indicator (SSI). Thereafter, an SB CQI of the better SB state of SB0 and SB1 in BP1 and an index of the corresponding SB are transmitted in the next CQI transmission subframe. Thus, CQI of each BP is sequentially transmitted after transmission of the WB CQI. The CQI of each BP may be sequentially transmitted once to four times during the interval between transmission intervals of two WB CQIs. For example, if the CQI of each BP is transmitted once during the time interval between two WB CQIs, CQIs may be transmitted in the order of WB CQI ?BP0 CQI?BP1 CQI?WB CQI. If the CQI of each BP is transmitted four times during the time interval between two WB CQIs, CQIs may be transmitted in the order of WB CQI ?BP0 CQI ?BP1 CQI?BP0 CQI?BP1 CQI?BP0 CQI?BP1 CQI?BP0 CQI?BP1 CQI?WB CQI. Information as to how many times each BP CQI is transmitted is signaled by a higher layer (RRC layer).
