Abstract: Apparatus, system and methods for evaluating link quality within a cellular system. A user equipment (“UE”) is connected to a network, wherein the UE communicates data to the network on an uplink (“UL”) link. The UE determines a requested buffer size for a UL communication, determines a transport block size for the UL communication based on a primary set of allocation parameters, and compares the requested buffer size to the transport block size to determine if a data rate for the UL communication satisfies a threshold. When the data rate satisfies the threshold, the UE identifies the UL link as a good quality link and sends acceptable link quality feedback to the network. When the data rate does not satisfy the threshold, the UE performs a further action to test a quality of the UL link.

Abstract: A method for reducing scheduling requests by a wireless communication device transmitting data using dynamically scheduled resources over a logical 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.
