The method comprises receiving a physical downlink control channel conveying a downlink control information (DCI) format, a physical downlink shared channel conveying one or more data transport blocks scheduled by the DCI format, and configuration information for transmission of a physical uplink control channel (PUCCH) conveying acknowledgement information in response to the reception of the one or more data transport blocks; and transmitting the PUCCH in time-frequency resources within a first slot. An index of the first slot is configured by the DCI format. The time-frequency resources within the first slot are configured by the DCI format through a configuration of an index of a first symbol, a number of consecutive slot symbols, and an index of a first frequency resource block. ## Claims ### Claim 1 A method for transmitting a physical uplink control channel (PUCCH), the method comprising: receiving a first downlink control information (DCI) format that triggers a transmission of the PUCCH; determining, based on an indication by the first DCI format: a first symbol in a slot, and a number of consecutive symbols in the slot; and transmitting the PUCCH over a first number of slots, wherein for each slot from the first number of slots: the PUCCH transmission starts at the first symbol, and the PUCCH transmission is over the number of consecutive symbols. ### Claim 2 (depends on 1) The method of claim 1, wherein: a field in the DCI format indicates a resource from a set of resources for the PUCCH transmission, and the resource includes the first symbol, the number of symbols, and the first number of slots. ### Claim 3 (depends on 1) The method of claim 1, wherein: the PUCCH transmission includes a codeword, the codeword is included in resources of the PUCCH transmission over one slot when a code rate of the codeword over the resources of the PUCCH transmission over one slot is smaller than or equal to a threshold, and the codeword is included in resources of the PUCCH transmission over more than one slot when a code rate of the codeword over the resources of the PUCCH transmission over one slot is larger than the threshold. ### Claim 4 (depends on 3) The method of claim 3, further comprising: receiving information for the threshold. ### Claim 5 A user equipment (UE), comprising: a transceiver configured to receive a first downlink control information (DCI) format that triggers a transmission of a physical uplink control channel (PUCCH); and a processor operably coupled to the transceiver, the processor configured to determine, based on an indication by the first DCI format: a first symbol in a slot, and a number of consecutive symbols in the slot, wherein: the transceiver is further configured to transmit the PUCCH over a first number of slots, wherein for each slot from the first number of slots: the PUCCH transmission starts at the first symbol, and the PUCCH transmission is over the number of consecutive symbols. ### Claim 6 (depends on 5) The UE of claim 5, wherein: a field in the DCI format indicates a resource from a set of resources for the PUCCH transmission, and the resource includes the first symbol, the number of symbols, and the first number of slots. ### Claim 7 (depends on 5) The UE of claim 5, wherein: the PUCCH transmission includes a codeword, the codeword is included in resources of the PUCCH transmission over one slot when a code rate of the codeword over the resources of the PUCCH transmission over one slot is smaller than or equal to a threshold, and the codeword is included in resources of the PUCCH transmission over more than one slots when a code rate of the codeword over the resources of the PUCCH transmission over one slot is larger than the threshold. ### Claim 8 (depends on 7) The UE of claim 7, wherein: the transceiver is further configured to receive information for the threshold. ### Claim 9 A base station, comprising: a transceiver configured to transmit a first downlink control information (DCI) format that triggers a reception of a physical uplink control channel (PUCCH); and a processor operably coupled to the transceiver, the processor configured to determine, based on an indication by the first DCI format: a first symbol in a slot, and a number of consecutive symbols in the slot, wherein: the transceiver is further configured to receive the PUCCH over a first number of slots, wherein for each slot from the first number of slots: the PUCCH reception starts at the first symbol, and the PUCCH reception is over the number of consecutive symbols. ### Claim 10 (depends on 9) The base station of claim 9, wherein: a field in the DCI format indicates a resource from a set of resources for the PUCCH reception, and the resource includes the first symbol, the number of symbols, and the first number of slots. ### Claim 11 (depends on 9) The base station of claim 9, wherein: the PUCCH reception includes a codeword, the codeword is included in resources of the PUCCH reception over one slot when a code rate of the codeword over the resources of the PUCCH reception over one slot is smaller than or equal to a threshold, and the codeword is included in resources of the PUCCH reception over more than one slots when a code rate of the codeword over the resources of the PUCCH reception over one slot is larger than the threshold.
