Transmission of UL control channels with dynamic structures
A method of a user equipment (UE) for transmitting acknowledgement information. 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.
