CPC H04W 28/06 (2013.01) [H04L 5/0005 (2013.01); H04W 72/0446 (2013.01)] | 20 Claims |
1. A method, comprising:
receiving control information from a network device, the control information comprising information about a time-frequency resource for transmitting a first data packet, the time-frequency resource comprising K transmission occasions;
sending the first data packet to the network device on at least one of the K transmission occasions, each of the K transmission occasions performing one data transmission on the first data packet, a quantity of valid resource elements (REs) comprised in a first transmission occasion in the K transmission occasions is greater than or equal to a quantity of valid REs comprised in a second transmission occasion in the K transmission occasions, K is an integer greater than 1, the time-frequency resource comprises a time-frequency resource crossing a slot boundary in time domain, and a time domain resource length corresponding to the time-frequency resource crossing the slot boundary corresponds to a time domain resource length that is of a single transmission occasion and that is notified by using the control information; and
the first transmission occasion corresponds to a time-frequency resource that is in the time-frequency resource crossing the slot boundary and that is located before the slot boundary, and the second transmission occasion corresponds to a time-frequency resource that is in the time-frequency resource crossing the slot boundary and that is located after the slot boundary; or
the first transmission occasion corresponds to a time-frequency resource that is in the time-frequency resource crossing the slot boundary and that is located after the slot boundary, and the second transmission occasion corresponds to a time-frequency resource that is in the time-frequency resource crossing the slot boundary and that is located before the slot boundary, wherein
a transport block size (TBS) corresponding to the first data packet is determined based on a target quantity of valid (REs), and the target quantity of valid REs is a quantity of valid REs comprised in a target transmission occasion.
