Abstract: Some aspects relate to apparatuses and methods for calculating an uplink pathloss in a wireless communication system. A user equipment (UE) can be configured to perform operations for calculating the uplink pathloss. The operations can include determining a transmission power of a physical uplink shared channel (PUSCH) transmission for a UE, TxpPUSCH, where the PUSCH transmission is from the UE to a base station. The operations can further include determining a receiving power of a sounding reference signal (SRS) by the base station, Rxpsrs; and further calculating the uplink pathloss based on the transmission power of the PUSCH transmission TxpPUSCH and the receiving power of the SRS Rxpsrs.

Abstract: Systems, methods, and apparatuses disclosed herein can mitigate transmitting latency to improve the quality of a voice or the video call. These systems, methods, and apparatuses reset a transmitting latency timer upon retrieving a packet from a transmitting buffer. Thereafter, these systems, methods, and apparatuses start the count of the transmitting latency timer as the packet is being processed. And these systems, methods, and apparatuses compare the transmitting latency timer e with a transmitting latency threshold as these systems, methods, and apparatuses are processing a packet for transmission. These systems, methods, and apparatuses can drop the packet and/or can select another packet for processing in response to the transmitting latency timer exceeding the transmitting latency threshold to mitigate the transmitting latency.
