Abstract: Various embodiments provide a communication method. The method includes: determining, by a terminal device, first uplink control information and second uplink control information. In those embodiments, a length of a time domain resource corresponding to the first uplink control information is less than a length of a time domain resource corresponding to the second uplink control information. The first uplink control information or the second uplink control information comprises at least one of hybrid automatic repeat request information, channel state information, and scheduling request information. When the time domain resource corresponding to the first uplink control information overlaps with the time domain resource corresponding to the second uplink control information, the terminal device is configured to transmit third uplink control information on the overlapping time domain resource.

Abstract: The present disclosure provides an information processing method and apparatus. A terminal device encodes uplink control information (UCI) to obtain coded bits of the UCI, and encodes data to obtain coded bits of the data. The terminal device multiplexes the coded bits of the UCI and the coded bits of the data to obtain a multiplexed bit sequence. The terminal device then transmits the multiplexed bit sequence to a network device via a physical uplink shared channel (PUSCH). A length of a transmission time interval of the UCI is less than or equal to 0.5 millisecond. In this way, data transmission latency can be reduced.

Abstract: The present disclosure relates to example data transmission methods, user equipment, and access network devices in an LAA-LTE system. An example data receiving method includes determining, by user equipment, first information of a first cell. The user equipment determines a first subframe based on the first information, where a downlink data transmission length of the first subframe is less than a first threshold. The user equipment then determines a data transmission characteristic of the cell in the first subframe based on a preset condition, so as to receive, based on the data transmission characteristic, data including the first subframe. In doing so, a data transmission characteristic of a base station or a terminal is standardized, and a reference signal such as a DRS can be correctly identified.
