Abstract: In an example embodiment, a method of reducing SR max retransmissions in a communication network is disclosed. The method includes: accessing an SR max retransmission UE pool stored in a storage of the base station, the SR max retransmission UE pool being a list of plurality of UEs which experienced SR max retransmission. The method further includes identifying at least one UE in the SR max retransmission pool that would enter an SR max retransmission state, based on a last PUSCH uplink time period and a SR max retransmission time period associated with the at least one UE. Further, the method includes allocating a dummy UL grant to the identified at least one UE.

Abstract: A method of optimizing uplink signal detection threshold is provided. The method includes initializing a current detection threshold in an allowable range of uplink detection thresholds for detection of a plurality of uplink signals for a predetermined time period and selecting and applying a detection threshold within a narrow window centered around the current detection threshold at the physical (PHY) layer. The method further includes determining whether a corresponding uplink signal among the plurality of uplink signals is detected correctly or falsely at a medium access control (MAC) layer and accumulating, for the applied detection threshold, the corresponding results of the determination at the MAC layer. The method further includes determining an optimal detection threshold from the narrow window based on an analysis of the accumulated results and applying the determined optimal detection threshold at the PHY layer as the current detection threshold for the detection of the plurality of uplink signals.
