Data transmission method and apparatus

A method comprising:

• determining a time domain resource of first uplink data based on whether a first time segment comprises a complete synchronization signal and physical broadcast channel block (SSB);
• and
• receiving the first uplink data based on the time domain resource of the first uplink data, wherein
• a start moment of the first time segment is n1+X+t1, and an end moment is n1+X+Y1−t2;
• n1 is a start moment of the first uplink data, X is a maximum duration for one time of uplink data sending, Y1 is a duration occupied by a gap between the first uplink data and second uplink data, and a time domain position of the first uplink data is before a time domain position of the second uplink data;
• and
• t1 is a preparation duration between sending and receiving of a first apparatus, t2 is a preparation duration between receiving and sending of the first apparatus, and t1 and t2 are integers greater than or equal to 0.

An apparatus, comprising:

• at least one processor;
• and
• a memory coupled to the at least one processor and having program instructions stored thereon which, when executed by the at least one processor, configure the apparatus to:
• determine a time domain resource of first uplink data based on whether a first time segment comprises a complete synchronization signal and physical broadcast channel block (SSB);
• and
• send the first uplink data based on the time domain resource of the first uplink data, wherein
• a start moment of the first time segment is n1+X+t1, and an end moment is n1+X+Y1−t2;
• n1 is a start moment of the first uplink data, X is a maximum duration for one time of uplink data sending, Y1 is a duration occupied by a gap between the first uplink data and second uplink data, and a time domain position of the first uplink data is before a time domain position of the second uplink data;
• and
• t1 is a preparation duration between sending and receiving of a first apparatus, t2 is a preparation duration between receiving and sending of the first apparatus, and t1 and t2 are integers greater than or equal to 0.
