Abstract
A method for reducing scheduling requests by a wireless communication device transmitting data using dynamically scheduled resources over a logical channel is provided. The method includes receiving, at the wireless communication device, a configuration from a network entity that sets a LogicalChannelSR-Mask for a logical channel for which uplink resources can be dynamically scheduled by the wireless network. The method further includes waiting to send a scheduling request (SR) for a delay time period when data is available to be sent on the logical channel and uplink resources have not been granted. The method additionally includes using the grant to send the data without sending an SR when a grant is received within the delay time period; or sending an SR when a grant is not received within the delay time period. In another method, a network selectively enables or disables SRs for a logical channel through explicit signaling.
