  • Publication number: 20220039088
    Abstract: A method and apparatus are provided for transmitting and receiving control information. A method performed by a UE includes receiving, from a base station, DCI or a higher layer signaling; when first priority UCI and second priority UCI are transmitted in a same physical uplink channel, separately encoding the first priority UCI and the second priority UCI, based on a first number of bits of the first priority UCI and a second number of bits of the second priority UCI; and transmitting, based on the DCI or the higher layer signaling, the encoded first priority UCI and the second priority UCI, to the base station, on the same physical uplink channel.

  • Publication number: 20210359796
    Abstract: Method for generating a semi-static HARQ-ACK codebook, user terminal, and readable storage medium. The method comprises: receiving a PDSCH transmitted by a base station and a HARQ-ACK feedback time, the PDSCH transmitted by the base station being sent after the base station detects the success of LBT; generating a semi-static HARQ-ACK codebook during a current channel occupation duration according to the PDSCH transmitted by the base station and the HARQ-ACK feedback time, the semi-static HARQ-ACK codebook comprising a first sub-codebook and a second sub-codebook, wherein the first sub-codebook is used for the feedback of a HARQ-ACK, indicated in the HARQ-ACK feedback time, corresponding to the PDSCH for the last X timeslots in the previous channel occupation duration, and the second sub-codebook is used for the feedback of a HARQ-ACK, indicated in the HARQ-ACK feedback time, corresponding to a PDSCH for the time slot in the current channel occupation duration.

  • Publication number: 20210307004
    Abstract: A service conflict processing method, a user terminal, and a computer-readable storage medium. The method comprises: determining whether UCI of an eMBB service currently being transmitted collides with data or UCI of an URLLC service with respect to transmission time, wherein the UCI of the eMBB service comprises HARQ-ACK information; and if the UCI of the eMBB service has collided with the data or the UCI of the URLLC service with respect to transmission time, delaying the transmission of the UCI of the eMBB service. The solution can be employed to improve spectral efficiency of the system.

  • Publication number: 20210242980
    Abstract: UE, base station and data transmission method and apparatus. The method includes: in an unlicensed frequency band of 5G NR, a UE transmitting uplink data and associated UCI to a base station through AUL transmission; the base station identifying the UE through UE specific DMRS; the base station decoding the UCI; if the UCI is successfully decoded, the base station decoding the uplink data; based on whether a transport block or CBG is successfully decoded, the base station transmitting DFI to the UE, the DFI including first information used to indicate a location of the successfully decoded CBG; the UE receiving the DFI; the UE using the first information to determine HARQ-ID of a transport block where the CBG that needs to be retransmitted is located, and a sequence number of the CBG in a HARQ of the transport block where the CBG is located; the UE performing scheduling-free retransmission.

  • Publication number: 20190222366
    Abstract: Method for generating a HARQ codebook, a user equipment and a medium are provided. The method includes: receiving PDSCHs each of which includes at least one TB; and to serving cells which are configured with CBG-based HARQ feedback, generating a HARQ codebook corresponding to the PDSCHs using N bits per PDSCH, wherein N is a maximum value of numbers of CBGs corresponding to the PDSCHs. Bit overhead of the CBG-based HARQ feedback may be reduced, and resource utilization may be improved.
