Method and apparatus for setting transmission time advance

A timing advance (TA) setting method, applied to a base station, comprising:

• detecting, on a first target resource, whether a random access signal sent by a client is received;
• wherein the first target resource is a random access resource which is associated with a second target resource and meets specified conditions, and the second target resource is any resource unit in a resource set which is pre-allocated to the client by the base station and configured to perform unlicensed data reporting;
• re-configuring, in response to the random access signal being detected on the first target resource, a new TA for the client according to the random access signal;
• returning the new TA to the client;
• and
• receiving target data which is sent by the client through the second target resource based on the new TA, wherein the target data is data which needs to be reported to the base station by the client presently.

A timing advance (TA) setting device, applied to a base station, comprising:

• a processor;
• and
• a memory for storing instructions executable by the processor;
• wherein the processor is configured to:
• detect, on a first target resource, whether a random access signal sent by a client is received;
• wherein the first target resource is a random access resource which is associated with a second target resource and meets specified conditions, and the second target resource is any resource unit in a resource set which is pre-allocated to the client by the base station and configured to perform unlicensed data reporting;
• re-configure, in response to the random access signal being detected on the first target resource, a new TA for the client according to the random access signal;
• return the new TA to the client;
• and
• receive target data which is sent by the client through the second target resource based on the new TA, wherein the target data is data which needs to be reported to the base station by the client presently.
