Method of sending uplink control channel and device thereof, method of receiving uplink control channel and device thereof, terminal and base station

A method of receiving an uplink control channel, comprising:

• determining a plurality of target slots for sending uplink control information to be fed back, wherein the uplink control information to be fed back is sent in the target slots through an uplink control channel;
• acquiring a transmission duration or format of the uplink control channel carrying the uplink control information to be fed back in each of the target slots, wherein the transmission duration or format of the uplink control channel in every target slot is the same;
• and
• receiving, in each of the target slots, the uplink control information sent through the uplink control channel, according to the determined transmission duration or format of the uplink control channel;
• wherein the receiving the uplink control channel carrying the uplink control information to be fed back in each of the target slots comprises:
• in the case that a size of the uplink control information to be fed back is smaller than or equal to a first preset value, receiving the uplink control channel carrying a modulation symbol in each of the target slots, wherein the modulation symbol is acquired by modulating the uplink control information to be fed back by a terminal;
• in the case that the size of the uplink control information to be fed back is larger than the first preset value, receiving the uplink control channel carrying a first bit sequence in each of the target slots, or in the case that the size of the uplink control information to be fed back is larger than the first preset value, receiving, in each target slot, the uplink control channel carrying a sub bit sequence of a second bit sequence corresponding to the each target slot;
• wherein the first bit sequence is an encoded bit sequence acquired by performing by the terminal a channel coding and a rate matching for the uplink control information to be fed back according to a quantity of symbols carrying the uplink control information in the uplink control channel;
• the second bit sequence is an encoded bit sequence acquired by performing by the terminal a channel coding and a rate matching for the uplink control information to be fed back according to the quantity of symbols carrying the uplink control information and a quantity of the target slots in the uplink control channel.

A device of sending an uplink control channel, comprising:

• a processor, a memory and a computer program stored in the memory and executable by the processor, wherein the computer program is executed by the processor to:
• determine a plurality of target slots for sending uplink control information to be fed back, wherein the uplink control information to be fed back is sent in the target slots through an uplink control channel;
• acquire a transmission duration or format of the uplink control channel carrying the uplink control information to be fed back in each of the target slots, wherein the transmission duration or format of the uplink control channel in every target slot is the same;
• and
• send, through the uplink control channel, the uplink control information to be fed back in each of the target slots, according to the determined transmission duration or format of the uplink control channel;
• wherein the computer program is executed by the processor to:
• in the case that a size of the uplink control information to be fed back is smaller than or equal to a first preset value, modulate the uplink control information to be fed back to obtain a modulation symbol, and repeatedly send the uplink control channel carrying the modulation symbol in each of the target slots;
• in the case that the size of the uplink control information to be fed back is larger than the first preset value, perform a channel coding and a rate matching for the uplink control information to be fed back, according to a quantity of symbols carrying the uplink control information in the uplink control channel, to obtain an encoded first bit sequence, and repeatedly send the uplink control channel carrying the first bit sequence in each of the target slots;
• or in the case that the size of the uplink control information to be fed back is larger than the first preset value, perform a channel coding and a rate matching for the uplink control information to be fed back, according to a quantity of symbols carrying the uplink control information and a quantity of the target slots in the uplink control channel, to obtain an encoded second bit sequence, and send, in each target slot, the uplink control channel carrying a sub bit sequence of the second bit sequence corresponding to the each target slot.
