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.

Abstract: Aspects are described for a user equipment (UE) comprising a transceiver configured to enable wireless communication with a base station; and a processor communicatively coupled to the transceiver. The processor is configured to receive a sounding reference signal (SRS) resource configuration from the base station, wherein the SRS resource configuration indicates at least a first SRS resource and a second SRS resource. The processor is further configured to transmit a first SRS via the first SRS resource to the base station using a first antenna coupled to the transceiver and transmit a second SRS via the second SRS resource to the base station using a second antenna coupled to the transceiver. The processor is further configured to receive an SRS resource indicator (SRI) from the base station based on at least one of the transmission of the first SRS or the second SRS; select the first antenna based on the SRI indicating the first SRS resource; and transmit uplink data to the base station using the first antenna.

Abstract: A device, system and method for a user equipment (UE) to report a network resource and capability state to a network for coordinating network resource allocations. The UE is configured to establish a first connection to a first network based on a first subscriber identity module (SIM) of the UE and further configured to establish a second connection to a second network based on a second SIM of the UE. The method includes determining an upcoming first change of a state of the UE with respect to the first connection and transmitting, to the first network, an indication of the first change of state of the UE. The method further includes changing the state of the UE with respect to the first connection.
