Abstract: Embodiments of this application provide a beam training method and an apparatus, to improve beam training performance. The method includes: The first apparatus determines a quasi co-location assumption of a first reference signal, and receives, based on the quasi co-location assumption of the first reference signal, the first reference signal sent by a second apparatus. The quasi co-location assumption meets at least either of the following conditions: A plurality of periodic instances of the first reference signal at an interval of N periodicities have a same quasi co-location assumption, where N is an integer greater than 0; and first reference signals that have different indexes and that are in a same resource set have different quasi co-location assumptions.

Abstract: This application relates to the field of communication technologies, and provides a reference signal resource determining method and an apparatus. In a multi-point transmission mode, uplink sending occurs between reference signals from different transmission points in a CSI measurement process; consequently, phases are discontinuous on the reference signals received by a terminal device from the different transmission points. First, configuration information of a reference signal resource set is obtained to determine K reference signal resources, where K is a positive integer, and slots in which at least two of the K reference signal resources are located are different slots, or there is an uplink symbol in a first interval of at least two of the K reference signal resources.

Abstract: Embodiments of this application provide a reference signal (RS) sending method and a communication apparatus, which may be applied to a scenario in which an RS is sent based on aperiodic time-domain behavior. The method may include: A terminal device obtains downlink control information (DCI); determines first time information based on the DCI; determines, based on the first time information and a time unit in which the DCI is located, a time unit for sending an RS; and sends the RS in the determined time unit for sending the RS. Correspondingly, a network device determines the first time information based on the DCI; determines, based on the first time information and the time unit in which the DCI is located, a time unit for receiving the RS; and receives the RS in the determined time unit for receiving the RS.

Abstract: The disclosure provides example communication methods and apparatuses. One example method includes determining a highest-priority CORESET, so that a terminal device monitors a PDCCH on the highest-priority CORESET. A highest-priority CORESET is determined in M CORESETs belonging to T CORESETs based on one or more of cell identifiers, quasi co-location properties, search space set types, and search space set identifiers that are associated with the M CORESETs in a time unit, and a PDCCH is monitored on the highest-priority CORESET.

Abstract: This application provides a PDSCH transmission method and apparatus, and relates to the field of communication technologies, to reduce complexity of processing a PDSCH by a terminal device. The method includes: The terminal device receives first DCI and second DCI. First indication information included in one piece of DCI that is in the first DCI and the second DCI and that has the first indication information indicates whether one or more time-frequency resource groups in a first PDSCH and a second PDSCH are available. In this way, there is only one type of interference strength between the first PDSCH and the second PDSCH, and the terminal device may process the first PDSCH and the second PDSCH by using a descrambling manner corresponding to the interference strength. In this case, the terminal may receive both of the first PDSCH and the second PDSCH.
