Method and apparatus for determining resources for PUCCH transmission with acknowledgment information
Methods and apparatuses for determining and multiplexing acknowledgment information. A method for operating a user equipment includes receiving: information for first resources for physical uplink control channel (PUCCH) transmissions to provide hybrid automatic repeat request acknowledgement (HARQ-ACK) information in response to semi-persistently scheduled (SPS) physical downlink shared channel (PDSCH) receptions associated with a first radio network temporary identifier (RNTI) from a first set of RNTIs, and information for second resources for PUCCH transmissions to provide HARQ-ACK information in response to SPS PDSCH receptions associated with a second RNTI from a second set of RNTIs. The method further includes determining a first resource from the first resources for a first PUCCH to provide only: first HARQ-ACK information in response to first SPS PDSCH receptions associated with the first RNTI, and second HARQ-ACK information in response to second SPS PDSCH receptions associated with the second RNTI; and transmitting the first PUCCH.
