摘要： A communication method includes receiving, by a terminal device, first information from a network device. The first information indicates a precoding matrix. The communication method also includes determining, by the terminal device, the precoding matrix based on the first information. The precoding matrix is for sending an uplink signal. The precoding matrix is determined based on a first matrix and a second matrix. At least one of the first matrix is determined from a first matrix set based on the first information, wherein the first matrix set is determined based on a horizontal-dimension parameter of an antenna of the terminal device; or the second matrix is determined from a second matrix set based on the first information, wherein the second matrix set is determined based on a vertical-dimension parameter of the antenna.

摘要： An apparatus determines a timing offset of a first carrier and a second carrier. The timing offset is an offset between timing of downlink communication of the first carrier and timing of uplink communication of the second carrier. The first carrier is a carrier using a first radio access technology (RAT), and the second carrier is an uplink frequency division duplex (FDD) carrier using the first RAT and a second RAT. The apparatus sends first indication information to a terminal. The first indication information indicates the timing offset, and the timing offset is used to determine the timing of the second carrier.

摘要： Embodiments provide an information sending method, an information receiving method, a network device, and a terminal device, to enable the terminal device to determine a correct uplink transmission time, thereby avoiding an uplink transmission failure. For achieving this, a network device determines a first receiving start time and a first sending start time. The first receiving start time is a receiving time at which the network device starts to receive a signal in a first time period, and the first sending start time is a sending time at which the network device starts to send a signal in a second time period. The network device sends indication information to a terminal device to instruct the terminal device to determine a second sending start time. The second sending start time is determined based on the first receiving start time and the first sending start time.

摘要： Embodiments of this application provide an information sending method and an information receiving method. A network device receives a random access signal of a terminal device from the terminal device on a random access resource, where the random access resource is on a first uplink carrier or a second uplink carrier, and the first uplink carrier and the second uplink carrier are corresponding to a same downlink carrier; the network device determines a random access identifier corresponding to the random access resource according to a time-frequency resource sequence number of the random access resource and a carrier identifier of a carrier on which the random access resource is and the network device generates a random access response based on the determined random access identifier, and sends the random access response to the terminal device via the downlink carrier.
