20110038334 | METHOD AND APPARATUS FOR SEMI-PERSISTENT SCHEDULING FOR MULTIPLE UPLINK VOIP CONNECTIONS - Semi-Persistent Scheduling (SPS) addresses a variable number of sessions between nodes, such as an SPS operation applied on a radio bearer between a Remote evolved Base Node (ReNB) and a Donor evolved Base Node (DeNB). As the number of VoIP connections changes over time, the upper bound of the required uplink grant size also changes. Even if the number of VoIP connections is assumed to be fixed over a period of time, the superposition of “on” and “off” intervals of multiple VoIP calls will require the uplink grant size to change over time much more dynamically. Using a fixed uplink SPS size based on a fixed number of VoIP calls will result in inefficient use of uplink grants, (i.e., reserving more grants than needed) or Physical Downlink Control Channel (PDCCH) signaling overhead for VoIP packets that cannot be served by SPS. A set of solutions are provided for semi-persistently scheduling multiple VoIP connections between a ReNB and a DeNB so as to enhance efficient use of SPS and still meet Quality of Service (QoS) requirement(s) of VoIP traffic. | 02-17-2011 |
