Transmission timing adjustment method and device

An apparatus, comprising at least one processor and a memory coupled to the at least one processor, when executing programming instructions, the at least one processor being instructed to:

• send a random access preamble to a base station;
• receive a random access response from the base station, wherein the random access response comprises a first timing advance (TA) quantized value, and a quantity of bits occupied by the first TA quantized value is more than 11, wherein quantization precision of the first TA quantized value is M*Ts, M is a positive integer less than 16, and Ts has a value of 1/30.72 μs;
• determine a first transmission timing adjustment amount according to the first TA quantized value;
• and
• perform uplink transmission timing adjustment according to the first transmission timing adjustment amount.

A non-transitory computer readable storage medium, wherein the non-transitory computer readable storage medium stores a program which, when the program is executed by at least one processor, the following steps are performed:

• sending a random access preamble to a base station;
• receiving a random access response from the base station, wherein the random access response comprises a first timing advance (TA) quantized value, and a quantity of bits occupied by the first TA quantized value is more than 11, wherein quantization precision of the first TA quantized value is M*Ts, M is a positive integer less than 16, and Ts has a value of 1/30.72 μs;
• determining a first transmission timing adjustment amount according to the first TA quantized value;
• and
• performing uplink transmission timing adjustment according to the first transmission timing adjustment amount.
