    Abstract: A data transmission method is described that includes: receiving transmission feedback for one or more Code Block Groups (CBGs) from a receiver; transmitting one or more Transmission Blocks (TBs) based on the transmission feedback, wherein one of the one or more TBs comprises one or more retransmission CBGs and one or more initial transmission CBGs; in response to the one of the one or more TBs being an uplink transmission TB, obtaining, based on a correspondence between a number of the one or more retransmission CBGs carried by the one of the one or more TBs and scrambling sequences, scrambled information by scrambling a first check bit sequence, wherein the first check bit sequence is generated based on the transmission feedback and Uplink Control Information (UCI); and uplink-transmitting the UCI and the scrambled information.

    Abstract: A random access method and a device thereof are provided. The method includes that a base station receives a random access preamble and sends a Random Access Response (RAR) according to the random access preamble, where the RAR indicates at least two time-frequency units, and the at least two time-frequency units are time-frequency units having different time domains on an unlicensed channel. Further, the base station receives a first random access message 3 (MSG3) sent on a first time-frequency unit by a first terminal and sends a first random access message 4 (MSG4) to the first terminal, where the first time-frequency unit is any one of the at least two time-frequency units, where the first MSG3 includes a terminal identifier of the first terminal, where the first MSG4 carries a terminal identifier of the first terminal and a first Cell-Radio Network Temporary Identifier allocated to the first terminal.

    Abstract: Aspects of the present disclosure relates to a method, device, and system for transmitting data. The method can include receiving a transport block (TB) transmitted by a transmitting terminal, the TB comprising a plurality of code blocks (CBs), and determining an erroneous CB in the TB, and determining, according to a preset affiliation between CBs and code block groups (CBGs), whether each CBG includes an erroneous CB, any CB corresponding to m CBGs in the affiliation, and m being a preset positive integer. The method can further include, for each CBG, if the CBG includes an erroneous CB, determining that feedback information corresponding to the CBG is a negative acknowledgement (NACK), and if the CBG does not comprise an erroneous CB, determining that the feedback information corresponding to the CBG is a positive acknowledgement (ACK), and transmitting the feedback information corresponding to each CBG to the transmitting terminal.

    Abstract: A data receiving method includes: receiving first downlink control information; receiving first data in a subframe subsequent to a subframe corresponding to the first downlink control information; if second downlink control information is not received, storing the first data located between a current subframe and the subframe corresponding to the first downlink control information; if the second downlink control information is received, acquiring demodulation auxiliary information; receiving data overlapping in time domain and frequency domain in a subframe subsequent to a subframe corresponding to the second downlink control information, the overlapping data comprising second data and third data; demodulating the stored first data according to the demodulation auxiliary information to obtain demodulated data corresponding to second user equipment; determining the third data in the overlapping data according to the demodulated data corresponding to the second user equipment; and acquiring the second data from the overlapping data according to the third data.
