1. A method of controlling a multicast transmission, comprising:
- (a) transmitting a data packet to a plurality of slave devices across an ultra wideband (UWB) wireless network;
(b) detecting the reception of any acknowledgement transmissions, wherein each acknowledgement transmission indicates reception of the data packet by a respective one of the plurality of slave devices; and
(c) retransmitting the data packet to at least one of the plurality of slave devices when an acknowledgment is not detected for each of the plurality of slave devices.

Abstract
A method and system of controlling a multicast transmission. The method and system transmits a data packet to multiple slave devices across a UWB wireless network, and detects the reception of any acknowledgement transmissions. These acknowledgement transmissions indicate reception of the data packet by the slave devices. In addition, the method and system retransmit the data packet to at least one of the slave devices when an acknowledgment is not detected for each of the slave devices. The acknowledgments may be received from the UWB network.

13. A wireless communications device, comprising:
-
a transmission buffer configured to store a packet for transmission across an ultra wideband (UWB) wireless network to a plurality of slave devices;
a retransmission buffer configured to store a retransmission packet, the retransmission packet being previously transmitted across the UWB wireless network; and
a retransmission controller configured to receive one or more acknowledgment transmissions from the plurality of slave devices;
wherein the retransmission controller is further configured to cause the retransmission buffer to send the retransmission packet to the plurality of slave devices across the UWB wireless network when an acknowledgment is not detected for each of the plurality of slave devices. - View Dependent Claims (14, 15, 16)
