Abstract: A method of buffer status reporting for multiple preserved data protocol (PDP) contexts includes communicating with a base station. A service request is sent to the base station, the service request requesting a set of radio access bearers (RABs) for a set of PDP contexts. The set of preserved PDP contexts includes one or more PDP contexts that have no uplink data ready to transmit on a high speed shared data channel. The set of preserved PDP contexts also includes one or more PDP contexts that have uplink data ready to transmit on the high speed shared data channel.

Abstract: A method of wireless communication reports buffer size in TD-HSUPA networks. A protocol data unit is transmitted and an artificial buffer size is reported in response to the transmitted PDU. The artificial buffer size corresponds to the size of a scheduling request. The actual buffer size is reported when a NACK is received or when a round trip timer expires. The actual buffer size corresponds to a PDU retransmit size.

Abstract: A user equipment may save power and improve performance by adjusting a paging indicator detection threshold of power at which a user equipment (UE) determines a paging indicator channel transmission is received when detecting a signal on a paging indicator channel. The adjustment may be based on the UE's remaining battery power. When the battery power level is low, the threshold is increased to reduce false detections. When the battery power level is high, the threshold is decreased to increase the likelihood of detecting the signal on a paging indicator channel.

Abstract: A user equipment (UE) may scale down a signal strength of a radio access technology (RAT) cell in a report to a serving cell to avoid multiple connection attempts to the same radio access technology cell. The UE may initiate a predefined timer, called a target cell timer, on which the scaling down of the reported signal strength of the particular RAT cell is based. The timer is initiated when the UE returns back to the serving cell after failure to access a top ranked RAT neighbor cell.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a cellular modem may transmit, to an applications processor, an indication to use a non-Third Generation Partnership Project (non-3GPP) interworking function (N3IWF) for non-access stratum (NAS) signaling. Accordingly, the cellular modem may establish a first virtual interface with the applications processor. The cellular modem may further perform an Internet Key Exchange (IKE) procedure with a core network using the first virtual interface and the N3IWF and transmit a key generated during the IKE procedure to the applications processor. Numerous other aspects are described.

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 user equipment (UE) may establish a cellular connection with a base station associated with a cellular radio network. The UE may receive an access policy of the cellular radio network identifying an access preference rule for the UE to adopt for connections to a core network function of the cellular radio network, the access preference rule indicating for the UE to preferentially connect to the core network function via a non-cellular radio network. The UE may determine that a gateway between the non-cellular radio network and the core network function of the cellular radio network is not configured. The UE may determine that a gateway selection policy of the cellular radio network is not configured. The UE may establish a connection to a legacy core network function of a legacy cellular radio network via a legacy gateway.

Abstract: Methods, systems, and devices for wireless communications are described. In some systems, a user equipment (UE), such as a dual-subscription UE, support a first subscription and a second subscription. The first subscription may be in an active mode with a first cell and the second subscription may be in an idle mode with a second cell, and the UE may determine whether to exit or postpone entrance into a merged state in which the UE may perform idle mode measurements for the second subscription using the first subscription and the first cell based on a channel quality-based merge condition. For example, the UE may measure a channel quality associated with a communication link between the UE and the first cell and, in examples in which the measured channel quality fails to satisfy a threshold channel quality, the UE may exit or postpone entrance into the merged state.

Abstract: Methods, systems, and devices for wireless communications are described. Generally, the described techniques provide for identifying edge application servers (EASs) to support one or more services of an application client (AC) running on a user equipment (UE). An AC of a UE may send a request for an edge enabler client (EEC) of the UE to identify one or more EASs for one or more services of the AC. The EEC may receive the request and may perform an EAS discovery procedure to identify the one or more EASs. The EEC may then send a response to the AC including identifiers of the one or more EASs (e.g., if the EAS discovery procedure indicated that these EASs are available). Once the AC receives the response, the AC may connect to each EAS of the EASs indicated by the EEC to support a corresponding service of the AC.
