Abstract: Aspects of the present disclosure provide mechanisms for fast hyper frame number (HFN) resynchronization of Packet Data Convergence Protocol (PDCP) Protocol Data Units (PDUs). A wireless communication device (e.g., a PDCP entity at a wireless communication device) can calculate a current PDCP count of a current PDCP PDU of a plurality of PDCP PDUs received from a radio link control (RLC) sublayer based on a PDCP sequence number (SN) of the current PDCP PDU and an HFN of a first missing PDCP PDU after a successfully received PDCP PDU. The PDCP count may be calculated using the HFN of the first missing PDCP PDU in response to a gap between the PDCP count of the first missing PDCP PDU and the actual PDCP count of the current PDCP PDU being greater than a PDCP window size.

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: Methods, systems, and devices for wireless communications are described. In some systems, a user equipment (UE) may support one or more applications enabling various types of users to access relevant information relating to performance of the UE across one or more communication modes or radio access technologies (RATs). A type or granularity of the information that the UE provides to the user may depend on a type of the user. For example, if the UE detects that a user is a first user type, the UE may provide the user with relatively simpler or more basic information relating to UE performance. Alternatively, if the UE detects that a user is a second user type, the UE may provide the user with relatively more technical or granular information relating to UE performance. The UE may support a user interface via which the UE may present the information to a user.

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: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may identify that the UE is operating in a dual-connectivity configuration with a master node (MN) and a secondary node (SN). The UE may receive at least one request that the UE report MDT measurements. The UE may perform a first portion of measurements associated with the first base station and perform a second portion of measurements associated with the second base station. The UE may perform the measurements while the UE is operating in the dual-connectivity configuration. The UE may transmit one or more reports including information indicative of the first portion of measurements, information indicative of the second portion of measurements, or both.

Abstract: Methods, systems, and devices for wireless communications are described. A UE may establish a wireless communication link with a base station in accordance with a radio access technology (RAT), and an internet connection with the base station. The UE may identify a lack of support by a network that includes the base station for a type of voice calls associated with the RAT. The UE may transmit a discovery query for a gateway to a core network, and the UE may establish a connection with the gateway via the internet connection. The UE may initiate a voice call via a call path from the UE to the core network, where the call path may include the wireless communications link with the base station in accordance with the RAT and also may include the internet connection with the gateway.

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: Method and apparatus for a configuration for optimizing operations between TNs and NTNs. The apparatus transmits, to a first network connected to the UE, an indication of a network preference for a second network based on at least an application at the UE. The apparatus communicates with the first network or the second network after sending the indication. The apparatus may switch to the second network automatically in response to transmission of the indication. The apparatus may measure a signal corresponding to the second network to determine a coverage quality of the second network. The apparatus may receive a transition indication to transition to a cell associated with the second network in response to the indication of the network preference for the second network.

Abstract: An apparatus for wireless communication is provided. The apparatus may be a user equipment (UE). The apparatus receives a token from a first server in an edge data network. For example, the first server may be an edge application server (EAS). The apparatus transmits identification information associated with the apparatus to a second server of the edge data network. For example, the second server may be an edge enabler server (EES). The identification information includes at least the token, an identifier of the apparatus, and an identifier of the first server, wherein the identifier of the apparatus is independent of an Internet Protocol (IP) address of the apparatus.

Abstract: Methods, systems, and devices for wireless communications are described. For example, the described techniques provide for a user equipment (UE) to predict a gain state for an initial acquisition procedure. For example, the UE may use a machine learning (ML) model to predict an initial gain state which is likely to result in a successful initial acquisition procedure (e.g., without adjusting the gain state and reattempting the initial acquisition procedure). The UE may input UE history data or crowdsourced data (e.g., from a local network or a cloud-based server) into the ML model to generate a predicted gain state which may be more likely to result in a successful initial acquisition (e.g., without reattempting the initial acquisition procedure). The UE may use the initial gain state generated by the ML model to attempt an initial acquisition procedure with a network entity.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may disconnect from a first radio access technology (RAT) service, independent of signaling from the first RAT service, after sensing that the UE has entered a coverage hole. The UE may use a connection to a second RAT service while in the coverage hole in association with disconnecting from the first RAT service. The UE may disconnect from the second RAT service, independent of signaling from the second RAT service, after sensing that the UE has exited the coverage hole and before expiration of a radio link failure (RLF) timer for the second RAT service. The UE may reconnect to the first RAT service before expiration of an RLF timer for the first RAT service. Numerous other aspects are described.

Abstract: Certain aspects of the present disclosure provide techniques for reporting an indication of a power headroom report (PHR) when the UE's assigned of UL resources is insufficient to transmit both UL data and a PHR. Additionally, aspects described herein introduce a negative PHR used to indicate the UE requires additional UL resources.
