Abstract
A method for multicasting a packet begins by providing a buffer for each of two user equipments (UEs) in communication with a base station. A determination is made whether there is a previously unsent packet at the base station. A second determination is made whether both UE buffers are non-empty. A non-empty buffer is flushed if there is no previously unsent packet and if one of the buffers is non-empty. A packet is selected to be transmitted if there is a previously unsent packet or if both buffers are non-empty. The buffers are updated based on feedback received from the UEs.
Claims31
A method for multicasting a packet, comprising:
- providing a buffer for each of a plurality of user equipments (UEs) in communication with a base station, wherein each buffer stores indices of packets that have been transmitted but not acknowledged by the corresponding UE;
- determining whether there is a previously unsent packet at the base station;
- flushing the buffers on a condition that there is no previously unsent packet;
- selecting a packet to transmit on a condition that there is a previously unsent packet;
- and
- updating the buffers based on feedback received from the UEs.
