Abstract: This application discloses a communication method and a communications apparatus. User equipment transmits uplink data by using a first transmission parameter set when a time interval from a current moment to a latest moment at which uplink timing information is received is less than or equal to a first time interval; or transmits uplink data by using a second transmission parameter set when a time interval from a current moment to a latest moment at which uplink timing information is received is greater than the first time interval, where a transmission parameter included in the first transmission parameter set is different from that included in the second transmission parameter set. Different transmission parameter sets are used to transmit the uplink data at different time intervals based on the time interval from the current moment to the latest moment at which the uplink timing information is received.

Abstract: This application relates to the field of wireless communication technologies. A terminal device receives configuration information, which indicates that one first combination is mapped to a plurality of downlink reference signals, and one first combination is mapped to a plurality of second combinations. The terminal device then determines a mapping relationship between a first combination and downlink reference signals, a mapping relationship between a first combination and second combinations, and a mapping relationship between second combinations and downlink reference signals based on the configuration information. Next, a first preamble is sent on a first RO included in a first combination, and a first uplink reference signal is sent on a first PO included in a second combination. The selected first combination has a mapping relationship with the selected second combination. A selected downlink reference signal group is indicated by the selected first combination.

Abstract: This application discloses a communication method and an apparatus. A principle of the method is as follows: A spreading factor of a spreading block is adjusted based on available resource elements REs in a time-frequency resource block, then, the spreading block is generated by using the adjusted spreading factor, and finally, the generated spreading block is mapped to the available resource elements in the time-frequency resource block for sending. In this way, a requirement that “locations of spreading blocks of a plurality of users need to be aligned” can be satisfied, and no complex symbol is discarded, so that detection performance of the spreading blocks is ensured.
