BURST SLOT NUMBERING FOR LICENSED ASSISTED ACCESS

摘要

In one aspect of the teachings herein, a transmitter uses a burst numbering scheme to dynamically number the transmit slots comprising a burst transmission on a secondary carrier operated in unlicensed spectrum, where the secondary carrier is time aligned with a primary carrier that operates in licensed spectrum and uses a fixed numbering scheme for its transmit slots. By assigning the transmit slot numbers dynamically, the transmitter has foreknowledge of the transmit slot numbers of the transmit slots within the transmit burst, and can therefore carry out processing that is dependent on the transmit slot number(s) assigned to the transmit slots comprising the burst, even when the burst start time is variable. Correspondingly, a receiver also has foreknowledge of the transmit slot numbers associated with a received burst that was dynamically numbered by a transmitter according to a burst numbering scheme known to the receiver.
