Abstract
A wireless star network includes including a master node (master) and a set of N slave nodes (slaves), wherein the network uses orthogonal frequency division multiple access (OFDMA). The master partitions the set of slaves in a first subset A(i) and second subset B(j), wherein the first and second subsets are disjoint. Packets are transmitted by the first subset of slaves only while the master and second subset of slaves operate in receive mode, and packets are transmitted by the second subset of slaves only while the master and first of slaves operate in receive mode.

A method for communicating packets in a wireless star network, including a master node (master) and a set of N slave nodes (slaves), wherein the network uses orthogonal frequency division multiple access (OFDMA), comprising:
- partitioning, by the master, the set of slaves in a first subset A(i) and second subset B(j), wherein the first and second subsets are disjoint;
- transmitting packets by the first subset of slaves only while the master and second subset of slaves operate in receive mode;
- and
- transmitting packets by the second subset of slaves only while the master and first of slaves operate in receive mode.
