higher priority control information needs to be transmitted on the uplink pucch in place of a scheduled wideband pmi and cqi report then that scheduled wideband pmi cqi transmission is dropped for that reporting instance and may be transmitted on a subsequent reporting instance preferably the next reporting instance this may involve a subsequent sub band cqi report being omitted analogously to the omission in fig3 d and 3 e in the case where the ri transmission on pucch is dropped both ue and base station enode b assume a default ri value ri 1 in the case where the wideband cqi or the wideband cqi pmi transmission on pucch is dropped then a for non frequency selective cqi report modes do nothing since the wideband cqi or wideband cqi pmi will anyway be transmitted at the next reporting instance b for frequency selective cqi report modes do nothing and wait for the next wideband cqi pmi reporting instance or retransmit the wideband cqi or the wideband cqi pmi in place of a single sub band cqi report and then go back to the normal reporting instants the above solution guarantees a default mode of operation that is agreed between the ue and the e node b with the approach based on a default rank mode both the ue and the e node b can safely rely on a fallback transmission mode in case of drop of information this is in contrast to the techniques of the prior art where ri retransmission forces the enode b.
