An exemplary method of communicating includes multiplexing control signaling in a physical uplink control channel (PUCCH) onto a physical uplink shared channel (PUSCH) by puncturing PUSCH data with PUCCH control information using a uniform distribution of the PUCCH information within at least one resource block of the PUSCH data. One example includes using a first constant amplitude zero autocorrelation sequence (CAZAC) index on PUCCH for communicating CQI and ACK information together and using a second, different CAZAC sequence index for communicating CQI information alone or with NAK information or DTX. The used index provides an indication of whether ACK information is communicated. The used index also provides implicit DTX detection without additional processing.
