A method for wireless communication, comprising: receiving, by a user equipment, configuration information from a base station configuring multiple slots for a transmission on an uplink control channel, wherein the configuration information indicates: a starting slot for the transmission on the uplink control channel, a number of slots for the transmission on the uplink control channel, a starting symbol position in the starting slot for the transmission on the uplink control channel, and a number of symbols in the starting slot for the transmission on the uplink control channel; determining, by the user equipment, a subsequent slot in the multiple slots for the transmission on the uplink control channel according to the configuration information and an agreed rule specifying that a slot is the subsequent slot for the transmission on the uplink control channel when a number of symbols available for carrying the transmission on the uplink control channel in the slot is greater than or equal to the configured number of symbols in a slot, wherein a capability of orthogonal cover code multiplexing is same for the starting slot and the subsequent slot for the transmission on the uplink control channel; determining, by the user equipment, one or more symbols in the subsequent slot for the transmission on the uplink control channel according to the configuration information, wherein the agreed rule further specifies that the one or more symbols in the subsequent slot have a same position as one or more symbols in the starting slot; and performing, by the user equipment, the transmission on the uplink control channel using at least the starting slot and the subsequent slot. receiving, by a user equipment, configuration information from a base station configuring multiple slots for a transmission on an uplink control channel, wherein the configuration information indicates: a starting slot for the transmission on the uplink control channel, a number of slots for the transmission on the uplink control channel, a starting symbol position in the starting slot for the transmission on the uplink control channel, and a number of symbols in the starting slot for the transmission on the uplink control channel; determining, by the user equipment, a subsequent slot in the multiple slots for the transmission on the uplink control channel according to the configuration information and an agreed rule specifying that a slot is the subsequent slot for the transmission on the uplink control channel when a number of symbols available for carrying the transmission on the uplink control channel in the slot is greater than or equal to the configured number of symbols in a slot, wherein a capability of orthogonal cover code multiplexing is same for the starting slot and the subsequent slot for the transmission on the uplink control channel; determining, by the user equipment, one or more symbols in the subsequent slot for the transmission on the uplink control channel according to the configuration information, wherein the agreed rule further specifies that the one or more symbols in the subsequent slot have a same position as one or more symbols in the starting slot; and performing, by the user equipment, the transmission on the uplink control channel using at least the starting slot and the subsequent slot.
