Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may communicate with a base station according to a first radio access technology (RAT) in a first frequency range. The UE may perform measurements on a set of candidate cells of a second RAT or a second frequency range based on a determination for the UE to operate according to the second RAT or the second frequency range. The UE may perform a mobility procedure to establish a connection with a first cell of the set of candidate cells based on a determination that a first value of a first measurement parameter for the first cell satisfies a first threshold, and further based on a comparison of a different, second value of a second measurement parameter for the first cell to a second threshold.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a base station associated with a first radio access technology (RAT), a neighbor cell list including entries for at least a first set of neighbor cells and a second set of neighbor cells, the first set of neighbor cells and the second set of neighbor cells associated with a second RAT. The UE may determine that the first set of neighbor cells is associated with a first network operator and that the second set of neighbor cells is associated with a second network operator. The UE may measure at least one neighbor cell of the neighbor cell list based at least in part on prioritization of the first set of neighbor cells relative to the second set of neighbor cells. Numerous other aspects are described.

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.

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: 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.

Abstract: A user equipment (UE) configured for dual connectivity with a split bearer configuration may transmit uplink data packets to one or both a master cell group (MCG) and a secondary cell group (SCG). The UE may transmit an uplink transmission from a packet data convergence protocol (PDCP) entity over one or both of a first radio link control (RLC) entity associated with the MCG and a second RLC entity associated with the SCG. The configuration including a transmit buffer threshold. The UE may receive, at the PDCP entity, an uplink switch start indication. The UE may activate the second RLC entity in response to receiving the uplink switch start indication. The UE may transmit a buffer status report according to a current transmit buffer level plus the transmit buffer threshold. Accordingly, the UE may communicate with the SCG based on the uplink switch start indication.

Abstract: This disclosure provides systems, methods, and apparatuses for sharing a maximum transmit power limit between a first radio access technology (RAT) and a second RAT. In one aspect, a wireless communication apparatus may reduce the maximum transmit power limit of a first uplink signal associated with the first RAT to obtain a first transmit power. The wireless communication apparatus may allocate a second transmit power remaining from the maximum transmit power limit to a second uplink signal associated with the second RAT. The wireless communication apparatus may reduce the maximum transmit power limit when the wireless communication apparatus is located at a cell edge, and a higher priority of the first RAT in relation to the second RAT may otherwise result in the second transmit power of the second uplink signal not satisfying a threshold.

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) mitigates in-device interference caused by a simultaneous circuit-switched call on a first subscriber identity module (SIM) and another call on a second subscriber identity module (SIM) at the UE. The UE detects in-device interference between the circuit switched call and the other call. The UE then suspends the other call or reduces a transmit power of the other call when the in-device interference is above a predetermined threshold. The UE resumes the other call or increases the transmit power of the other call when the circuit switched call ends.

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: A method, an apparatus, and a computer program product for wireless communication are provided that may help account for scenarios in which a transport block size (TBS) for a retransmission may be determined based on a first grant, while a number of resource blocks (RBs) assigned for the retransmission may be determined from a second grant.

Abstract: Methods, systems, apparatus and computer program products are provided to improve synchronization of information units communicated in a wireless communication system. Timing misalignment in the transmission of adjacent information units can produce gaps or overlaps in the transmitted information. In a long-term evolution (LTE) wireless communication system, such gaps and overlaps can be eliminated or reduced by adjusting the lengths of a cyclic prefix portion of one or more transmitted symbols. This Abstract is provided for the sole purpose of complying with the Abstract requirement rules that allow a reader to quickly ascertain the disclosed subject matter. Therefore, it is to be understood that it should not be used to interpret or limit the scope or the meaning of the claims.

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: A wireless communications method is provided. The method includes analyzing one or more channel conditions from a wireless communication and automatically adjusting a frequency tracking loop gain or a time tracking loop gain in view of the channel conditions.
