Abstract: In a data sending method, a terminal device receives first control information in a first time unit. The first control information indicates a first time domain resource that is used to send a first information block. The terminal device receives the first information block on at least a part of the first time domain resource based on the first control information. The terminal device further receives second control information in a second time unit. The second control information indicates a second time domain resource that is used to send the first information block. The terminal device receives the first information block on the second time domain resource based on the second control information. The first time unit is different from the second time unit, and the first time domain resource and the second time domain resource have an overlapping time domain resource.

Abstract: This application provides a downlink information transmission method and apparatus, and a device. The method includes: encoding information into a plurality of transport blocks; determining a time-frequency resource used to send each transport block; sending downlink resource indication information to user equipment, where the downlink resource indication information indicates a time-frequency resource location occupied by an Mth transport block; and sending corresponding transport blocks on the time-frequency resources. The user equipment receives the transport blocks based on the downlink resource indication information and decodes the transport blocks to obtain the information, where the downlink resource indication information indicates a resource of only one transport block. A terminal device may determine a time-frequency resource location of another transport block based on a location parameter of the another transport block, and receive and decode the another transport block. Same information bits are carried in a plurality of transport blocks, so that transmission reliability can be effectively improved. There is no need to notify a time-frequency resource of each transport block, so that downlink control signaling overheads are effectively reduced.

Abstract: This application discloses a communication method and a communication apparatus. The method includes: A terminal device receives first indication information from a network device, where the first indication information indicates a first time interval. The first time interval is an interval between an end time point of a first signal and a start time point of a second signal. The terminal device receives or sends the second signal at least after the first time interval elapses after the first signal. The first signal and the second signal are sent in a same BWP. A first filter parameter corresponding to the first signal is different from a second filter parameter corresponding to the second signal. The first time interval is related to switching duration of the terminal device.

Abstract: A method for sending hybrid automatic repeat request acknowledgement/negative acknowledgement information and an apparatus are disclosed, and relate to the communications field, to specify a mechanism for feeding back information indicating whether a decoding result of downlink data repeatedly transmitted in a slot is correct. The method includes: determining a first downlink data occasion set based on a time domain resource indicated by a TDRA table; determining a first downlink data occasion based on a start time domain resource for sending downlink data; adding feedback information (for example, information indicating whether a decoding result of the downlink data is correct) to a feedback location corresponding to the first downlink data occasion; determining a feedback slot based on a slot to which the start time domain resource for sending the downlink data belongs and a first offset K1; and feeding back a HARQ-ACK codebook in the feedback slot.

Abstract: This application provides a feedback information transmission method and an apparatus. The method includes a terminal device that receives indication information from a network device. The indication information indicates to generate a semi-static codebook. The terminal device detects a first physical downlink shared channel (PDSCH) at M candidate receiving positions in a first time unit. The first PDSCH is a semi-persistent scheduling (SPS) PDSCH or a grant-free PDSCH, and M is a positive integer. The terminal device determines, based on a detection result of the first PDSCH, whether to send first feedback information to the network device. The first feedback information includes acknowledgement (ACK) information or negative acknowledgement (NACK) information indicating whether the first PDSCH detected at the M candidate receiving positions is correctly decoded.
