Abstract  Abstract

Uplink transmission scheduling requests (SRs) may be prohibited for a lower priority data flow logical channel group (e.g. VoIP configured with semi-persistent resource allocation) or other grouping but may still be triggered for higher priority traffic (e.g. data connected to a signaling radio bearer (SRB)). More efficient scheduling is also achieved by allowing an uplink transmission scheduler to distinguish between different priority flows or groups (e.g. LCGs) without a buffer status report (BSR). As a result when a semi-persistent resource is scheduled for the lower priority data there is less delay for high priority data while eliminating uplink and downlink control signaling i.e. fewer scheduling requests (SRs) and uplink grants for the lower priority data.
