Abstract

A communication method for wireless communication uses a TDMA (Time Division Multiple Access) super-frame structure for scheduling uplink and downlink transmissions between a first node and a second node, the second node receives receiving a downlink transmission from the first node and transmits an uplink response to the first node. The transmission of the uplink response is performed in an uplink frame of the super-frame structure. The uplink frame includes a field for uplink payload data and a field for time indicating data. The transmission of the uplink response includes transmitting time stamps in the time indicating data field, the time stamps indicating a time instance of the receiving of the downlink transmission, and the time instance of the transmitting of the uplink response. The time instances are determined using the clock of the second node.
