The code block group is one of a plurality of code block groups of a transport block that the terminal device received from a radio access network device, and the code block group includes at least one code block that is not transmitted correctly. The terminal device also receives a retransmission of the code block group from the radio access network device. The terminal device restores information carried in the received transport block. The identification information of the code block group is carried in downlink control information. The identification information of the code block group indicates which code block group of the transport block is retransmitted. The downlink control information further includes indication information that indicates whether the code block group is punctured or interfered.

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 discloses a data transmission method, a device, and a system, relates to the communications field, and can resolve a prior-art problem that a receive end cannot correctly receive data because a starting moment of sending information on a license-exempt spectrum cannot be determined. A specific solution is as follows: A first device detects first information of a first serving cell in a preset time period of a first subframe on a first time resource or a first time set of a subframe on a first time resource, determines a starting position of a second time resource according to the first information, and detects second information of the first serving cell in a second time set of a subframe on the second time resource. The present disclosure is used for data transmission.

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.
