Abstract: A method and device for determining the initial positions of a downlink data channel are provided. The method includes: a base station transmits to a terminal a generated indication signaling, and the terminal determines, on the basis of the received indication signaling, the time domain initial positions of the downlink data channel in L downlink TTIs. With the method, when the downlink control channel only appears in a part of the positions in a frequency domain or does not appear at all, and when the downlink control channel does not occupy the complete downlink control area in the time domain or the resources occupied by the downlink control channel in the time domain are variable, the base station can still accurately notify the terminal the time domain initial positions of the downlink data channel.

Abstract: Disclosed in the present application are an uplink control channel transmission method, a terminal, a base station and a device, for solving the problem, in the prior art, that no relevant solution addresses how to perform long NR-PUCCH transmission in multiple slots. The method applied to a terminal comprises: determining a total transmission length T of an uplink control channel (PUCCH) to be transmitted in P slots; determining the transmission structure of the PUCCH on the basis of T; and transmitting the PUCCH in the P slots according to the transmission structure. The present invention defines the transmission structure for long PUCCH transmission in multiple slots, realizing the normal transmission of the long PUCCH in multiple slots.

Abstract: The embodiments of the present application relate to a method for performing hybrid automatic repeat request feedback, and a terminal, for solving the problem existing in the prior art that there is no clear solution regarding how to perform feedback on HARQ-ACK of an SPS PDSCH. In the embodiments of the present application, the terminal adds or removes HARQ-ACK of an SPS PDSCH in an HARQ-ACK codebook transmitted over a PUCCH or a PUSCH, and transmits a processed HARQ-ACK codebook. Since the terminal can add or remove the HARQ-ACK of the SPS PDSCH in the HARQ-ACK codebook transmitted over the PUCCH or the PUSCH, a solution to perform feedback on the HARQ-ACK of the SPS PDSCH is given, improving system performance.
