Abstract: This disclosure provides a method for transmitting data on a physical uplink shared channel, a data transmission method, a terminal, a network device, and a chip system. A terminal receives indication information delivered by a plurality of network devices. The indication information is used to indicate a plurality of precoders (precoders). The terminal determines the plurality of precoders based on the indication information, and repeatedly sends a physical uplink shared channel PUSCH by using the plurality of precoders. Different precoders are used for at least two of the PUSCHs. In this disclosure, the PUSCH is repeatedly sent by using different precoders. This disclosure is applicable to 5G and future wireless networks.

Abstract: This application provides a communication method and a communications apparatus. A terminal may perform, based on first configuration information for a maximum of a first quantity of times, blind detection at PDCCH candidate locations configured by a network device for a first CORESET group. In comparison with a solution, in the conventional technology, in which the terminal blindly detects a PDCCH for all CORESETs in a target cell for a maximum of the first quantity of times, blind detection is performed for a CORESET corresponding to each TRP for a larger quantity of times. Therefore, scheduling flexibility can be improved.

Abstract: Embodiments of this application disclose a resource configuration method and apparatus, and a system. A network device sends, to a terminal device, resource configuration information of a demodulation reference signal DMRS resource that meets a predetermined rule. The terminal device receives the resource configuration information of a DMRS, where the received resource configuration information includes two or more groups, and the DMRS is used for demodulating a physical data channel. In the two or more groups of resource configuration information, a DMRS resource configured by any group of resource configuration information does not intersect with a physical data channel resource corresponding to another group of resource configuration information.

Abstract: This application provides a reference signal transmission method and an apparatus, used in a multipoint coordination transmission scenario. In one example method, a frequency domain resource that carries a target reference signal in a frequency domain resource or a time domain resource that is associated with each QCL assumption may be separately determined, and then the target reference signal carried on the frequency domain resource that is associated with the QCL assumption is separately received by using the corresponding QCL assumption.
