摘要： 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. This reduces complexity of processing the PDSCH by the terminal device.

摘要： A communication method and apparatus are provided. The method includes: A terminal determines a frequency hopping periodicity index of the terminal based on a first time unit. The terminal determines a first frequency hopping parameter based on the frequency hopping periodicity index of the terminal and a frequency hopping pattern, where the first frequency hopping parameter may be represented as khopping . The terminal sends a sounding reference signal SRS to a network device based on the first frequency hopping parameter. According to the method, the frequency hopping periodicity index can be associated with absolute time. For terminals multiplexed in a same configured bandwidth of an SRS, this can ensure that the different terminals perform SRS transmission in different subbands in a same time domain range, provided that corresponding kF is configured differently, reduce interference between SRS transmission while scheduling overheads are effectively reduced, and improve channel estimation precision.

摘要： This application provides an information transmission method and a communication apparatus. The method includes: A terminal device determines a first time resource, where the first time resource includes at least one time unit, and the first time resource is for sending a first reference signal RS. The terminal device determines a second time resource, where the second time resource includes at least one time unit, and the second time resource is for sending a second RS. There are K time units between the first time resource and the second time resource, and K is a natural number. K falls within a first value range, and a guard period GP between the first time resource and the second time resource includes a first quantity of time units. Alternatively, K falls within a second value range, and a GP does not exist. The terminal device sends the first RS on the first time resource, and sends the second RS on the second time resource. According to the foregoing method, in this application, a GP between different RSs is defined. This improves scheduling flexibility of a network device.
