Abstract: This disclosure provides a communication method to implement a function of a hybrid automatic repeat request (HARQ) feedback codebook in a multi-station scenario. In one example communication method performed by a communication apparatus comprises sending a plurality of configuration group identifiers, wherein a plurality of physical downlink shared channel (PDSCH) reception occasions correspond to the plurality of configuration group identifiers. Feedback information of the plurality of PDSCH reception occasions is received based on each of the plurality of configuration group identifiers and according to a predetermined rule of feedback sorting.

Abstract: This application provides a multi-downlink control information (DCI)-based transmission method. In the method, a terminal reports information about a capability of the terminal to support multi-DCI transmission, or a network device sends indication information of the types or the quantity of multi-DCI-based transmissions to a terminal. The network device performs resource scheduling on the terminal on this basis, thereby helping improve resource scheduling efficiency and reduce processing complexity of the terminal. In addition, this application also provides a corresponding solution for a scenario in which a carrier aggregation/dual connectivity (CA/DC) DCI-based transmission scenario coexists with multi-DCI (DCI)-based transmission, thereby helping the terminal share a multi-DCI DCI-based transmission capability and a CA/DC (DCI)-based transmission capability to improve a processing capability of the terminal.

Abstract: Example frequency domain resource allocation methods and apparatus are described. One example method includes determining M frequency domain resources according to a predetermined frequency domain resource allocation rule, and performing communication on one or more of the M frequency domain resources. Any two of the M frequency domain resources do not overlap. Each of the M frequency domain resources is associated with one piece of quasi-colocation (QCL) information, and any two of the M frequency domain resources are associated with different QCL information.

Abstract: Example communication methods and communications apparatus are described. One example method include: receiving downlink control information (DCI), where the DCI indicates N demodulation reference signal (DMRS) ports. The N DMRS ports correspond to each of M physical downlink shared channel (PDSCH) transmission units, at least two of the M PDSCH transmission units correspond to different transmission configuration indicator (TCI)-states, N is an integer greater than or equal to 1, and M are integers greater than or equal to 2. M PDSCHs are received based on the DCI.

Abstract: This application provides a UCI sending and receiving method and a communications apparatus. In the method, an association relationship between a PUCCH and a PUSCH is established, so that when resources of the PUSCH and the PUCCH overlap, a terminal device can determine UCI on which PUCCHs can be transmitted by multiplexing the resource of the PUSCH. A network device may receive the UCI on the PUSCH. Because the network device may know in advance which PUCCHs and PUSCHs are sent to the network device, the network device can demodulate and decode a signal on the received PUSCHs, to successfully obtain UCI. The network device can make a proper decision based on the UCI.

Abstract: A terminal device detects first DCI on a first PDCCH monitoring occasion, detects second DCI on a second PDCCH monitoring occasion, generates a hybrid automatic repeat request acknowledgement HARQ-ACK codebook based on the first PDCCH monitoring occasion and a DAI indication carried in at least one of the first DCI and the second DCI, and sends the HARQ-ACK codebook. The first DCI and the second DCI are for scheduling a same transport block TB, and the first DCI and the second DCI carry a same downlink assignment index DAI indication.
