1. A method, comprising:
receiving, at a user equipment, configuration information for more than one serving cell for a physical uplink control channel transmission within at least one physical uplink control channel cell group;
receiving configuration information comprising a time-domain pattern of a single physical uplink control channel cell within the at least one physical uplink control channel cell group;
determining a cell for the physical uplink control channel transmission of an uplink control information transmission based on the configured time-domain pattern;
multiplexing uplink control information and determining a physical uplink control channel resource according to the configuration information used on the determined cell for the physical uplink control channel transmission;
checking a validity of the determined physical uplink control channel resource on the determined cell for the physical uplink control channel transmission; and
transmitting the uplink control information on a physical uplink control channel or a physical uplink shared channel when the physical uplink control channel resource is valid,
wherein one of cells within the at least one physical uplink control channel cell group serves as a timing reference cell whose slot or sub-slot configuration is used to determine a timing from physical downlink shared channel transmission to hybrid automatic repeat request-acknowledgment transmission according to a timing parameter in downlink control information that schedules a physical downlink shared channel or activates a semi-persistent scheduling physical downlink shared channel transmission.
