Time multiplexing communication with secondary cells
First Claim
1. A method implemented by a network node of a cellular communication network, serving a plurality of user devices, the method comprising:
- determining a downlink (DL) buffer status for each of a plurality of secondary cells (SCells);
determining a transmission routine for each of the plurality of SCells, using radio channels in an unlicensed spectrum, each transmission routine having an associated transmission period, based on the respective downlink (DL) buffer status; and
time multiplexing transmission from the plurality of SCells to the plurality of user devices by executing the transmission routines during their respective transmission periods.

Abstract
A method implemented by a network node of a cellular communication network serving a plurality of user devices is disclosed. The method comprises determining a transmission routine for each of a plurality of secondary cells (SCells) using radio channels in an unlicensed spectrum. Each transmission routine has an associated transmission period based on a downlink (DL) buffer status. The method also comprises time multiplexing transmission from the plurality of SCells to the plurality of user devices by executing the transmission routines for their respective time periods. Network nodes, apparatus, computer programs associated with the method are also disclosed.
