Claim 16:
17. A communication system, comprising:
a terminal equipment comprises the apparatus according to claim 1; and
a network device comprises apparatus for receiving uplink control information configured to:
transmit configuration information via RRC signaling the configuration information is used for configuration of one or a plurality of channel access types for PUCCHs used for transmitting HARQ feedback information by a terminal equipment wherein the one or the plurality of channel access types comprising at least one of the following: a first channel access type not performing channel detection, a second channel access type containing a detection interval a third channel access type containing a detection interval and a contention window; and
receive a PUCCH with HARQ feedback information transmitted by the terminal equipment, wherein the PUCCH is transmitted, according to a channel access type of the PUCCH which is determined from the one or the plurality of channel access types, after a corresponding channel is detected as being idle by the terminal equipment, or without detecting the corresponding channel by the terminal equipment.
