  • Publication number: 20240129001
    Abstract: Systems, methods, and apparatuses disclosed herein can compensate for imbalances between multiple transport streams of an uplink (UL)-multiple-input and multiple-output (MIMO) transmission. These systems, methods, and apparatuses can adjust one or more signal metrics of multiple recovered transport streams of the UL-MIMO transmission that are received in the presence of imbalances between the multiple transport streams of the UL-MIMO transmission. As an example, these systems, methods, and apparatuses can inject noise into one or more of the multiple recovered transport streams to adjust the one or more signal metrics of the multiple recovered transmission streams to lessen the imbalances between the multiple transmission streams.

  • Publication number: 20240106610
    Abstract: The techniques provide solutions for a user equipment (UE) and base station to switch between T1R4 and 2T4R for sounding reference signals (SRS). The UE and base station may communicate SRS using 2T4R. The UE and/or base station may detect and evaluate a signal quality trigger and/or condition relating to switching from T2R4 to T1R4. The trigger and/or condition may correspond to a channel or radio frequency (RF) quality, conflicting or problematic band combinations used in a non-standalone (NSA) scenario, whether dedicated data subscription (DDS) subscriber identity module (SIM) or non-DDS SIM is being used in a dual SIM dual active (DSDA) scenario, etc. The UE and base station may either continue using T2R4 communications or switch to T1R4 communications based on the trigger and/or evaluation.

  • Publication number: 20240097807
    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.

  • Publication number: 20240098639
    Abstract: Systems and methods related to “on/off” determinations regarding the performance of physical downlink control channel (PDCCH) monitoring during connected mode discontinuous reception (CDRX) on duration windows are disclosed herein. In some cases, a radio access network (RAN) predicts whether a downlink (DL) packet for a UE will arrive at a buffer of the RAN prior to an end of a CDRX on duration window of the UE, and sends a downlink control information (DCI) with a cyclic redundancy check (CRC) scrambled by a power-saving radio network temporary identifier (PS-RNTI) (DCP) for the CDRX on duration window indicating whether or not the UE should perform PDCCH monitoring during the CDRX on duration window based on the prediction. In some cases, a UE determines a current state of DL traffic and adaptively uses DCP monitoring based on the current state of the traffic. Aggregation level adaptation by the RAN is also discussed.
