Frame structure and terminal synchronization method and apparatus in wireless communication system

An operation method of a first terminal in a wireless time sensitive network (WTSN), the operation method comprising:

• transmitting an uplink frame to an access point (AP);
• receiving a downlink frame from the AP, the downlink frame including compensation indication information indicating compensation to be performed by the first terminal based on channel information between the first terminal and the AP estimated based on the uplink frame;
• and
• performing the compensation based on the compensation indication information,
• wherein the uplink frame includes:
• a common preamble;
• and
• an uplink data unit for each of a plurality of terminals including the first terminal,
• wherein an uplink data unit for the first terminal includes an uplink U-header and a data field.

A first terminal operation in a wireless time sensitive network (WTSN), the first terminal comprising:

• a processor;
• a memory storing instructions executable by the processor;
• and
• a transceiver controlled by the processor,
• wherein when executed by the processor, the instructions cause the processor to:
• transmit an uplink frame to an access point (AP) through the transceiver;
• receive a downlink frame from the AP through the transceiver, the downlink frame including compensation indication information indicating compensation to be performed by the first terminal based on channel information between the first terminal and the AP estimated based on the uplink frame;
• and
• perform the compensation based on the compensation indication information,
• wherein the uplink frame includes:
• a common preamble;
• and
• an uplink data unit for each of a plurality of terminals including the first terminal,
• wherein an data unit for the first terminal includes an downlink U-header and a data field.
