    Abstract: Aspects are provided which allow a UE to disable measurements of reference signals from 5G base stations which are inapplicable to EN-DC. The UE may receive a reference signal from a base station. The UE may identify a frequency range. The UE may determine whether to measure the reference signal based on whether the reference signal is within the identified frequency range. The UE may refrain from measuring the reference signal in response to the determination. The UE may also refrain from measuring the reference signal in response to a SIB received at the UE not including a ULI, or in response to a frequency associated with the reference signal not being in a list of supported bands for EN-DC. As a result, inter-RAT handovers from LTE base stations to 5G base stations are prevented, UE power consumption is thereby saved, and support for EN-DC is maintained.

    Abstract: Methods, systems, and devices for wireless communications are described. A receiving device may receive, at a first operational layer of the receiving device, one or more protocol data units (PDUs) within a set of PDUs. The receiving device may identify, at a second operational layer of the receiving device, a sequence gap associated with a missing PDU from the set of PDUs, the first operational layer being a lower operational layer of the receiving device than the second operational layer. The receiving device may determine, at the second operational layer, that a triggering condition associated with the missing PDU has occurred. The receiving device may provide, by the second operational layer and based at least in part on the triggering condition occurring, an indication to update a reception buffer of the first operational layer to a last received protocol data unit of the set of PDUs.

    Abstract: A user equipment (UE) may simulate transmissions received from a BS to perform on-device testing of the UE. For example, the UE may be configured to loopback uplink data from the UL data path and input the uplink data as simulated downlink data for processing in the DL data path. The uplink data may include data related to a video call or network diagnostics. The user application data generated by the application and proceeding through the UL data path may be used to validate the DL data path. Downlink control information (DCI) may be determined by the UE and provided to the DL data path to accompany the uplink data. The DCI may include simulated uplink grants and/or simulated downlink scheduling assignments. The simulated downlink scheduling assignments may be determined based on availability of the uplink data in the UE's memory.

    Abstract: A UE may improve power performance by adjusting measurement reports based on uplink power. The UE factors in the uplink transmit power into the downlink radio signal strength measurement results that are reported to a network. When the UE is transmitting higher than normal uplink power, the UE can adjust the measurement results and report an artificially lower measurement result to the network, to account for the uplink transmit power. The UE may trigger a handover based at least in part on the adjusted measurement report.

    Abstract: This disclosure provides systems, methods, and apparatuses to manage mobility in a wireless communication system. A user equipment (UE) may include a wireless communication apparatus and an application processor (AP). In some aspects, the wireless communication apparatus may monitor cells using a first criterion to detect problematic cells. For example, the first criterion may be associated with a history of ping-pong events or a history of data transmission errors. The wireless communication apparatus may select a cell for communication using a cell selection criteria that deprioritizes selection of problematic cells. In some aspects, the wireless communication apparatus may receive a list of cells from the AP or a server, the list identifying cells considered to be problematic cells. The wireless communication apparatus may adjust the first criterion to expedite detection of problematic cells. In some aspects, the server may aggregate and redistribute information about problematic cells from a plurality of UEs.

    Abstract: A user equipment (UE) may reduce the difference in transmit power between the uplink channel and enhanced high speed channel so that the base station may decode the uplink channel. The UE may determine the transmit power level for the uplink channel, such as dedicated physical channel, and the transmit power level for the enhanced high speed channel, such as shared information channel, and reduce the power difference when the power difference is greater than a threshold. The power difference may be reduced by increasing or decreasing the power of the enhanced high speed channel and/or increasing or decreasing the power of the uplink channel.

    Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may establish, by a first subscription of the UE, a connection to a first network entity using two transmit (Tx) chains of the UE. The UE may receive, by a second subscription of the UE, a paging message from a second network entity. The UE may receive, by the first subscription from the second subscription, a request for the first subscription to enter a mode that supports one Tx chain. The UE, by the first subscription, may reduce the two Tx chains to the one Tx chain for the first subscription. The UE may perform, by the second subscription to the second network entity, the connection setup based at least in part on the first subscription reducing the two Tx chains to the one Tx chain. Numerous other aspects are described.
