Abstract: Methods and apparatuses for providing support for location and emergency calls for an over-the-top (OTT) service provider (SP) are disclosed. An access network node receives a first message from a UE, determines a location reference for the UE, and sends a second message including the location reference to the UE. The access network node may determine the location reference itself on behalf of a location server or may request the location server to assign and return the location reference. The access network node may serve as a proxy and avoid interaction between the UE and the location server. The location server may later receive a location request for the UE from a network entity wherein the location request includes the location reference. The location server may locate the UE using the location reference and return the UE location to the network entity.

Abstract: Methods and apparatuses for supporting location and emergency calls for an over-the-top (OTT) service provider are disclosed. A UE may send a request for an emergency call to an OTT service provider and may include in the request mobile network operator (MNO) data for a serving MNO for the UE. The OTT service provider may forward the emergency call request to an Internet Protocol (IP) Multimedia Subsystem (IMS). The IMS may determine routing information for the emergency call and either return the routing information to the OTT service provider to enable the OTT service provider to route the emergency call to a public safety answering point (PSAP) or may route the emergency call itself to the PSAP. The call request routed by the IMS or by the OTT service provider may include a reference identifier that may enable the PSAP to obtain a location for the UE from the IMS.

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, a synchronization signal block (SSB) associated with an SSB configuration for an operating band having a maximum bandwidth that is narrower than a minimum SSB bandwidth for an access link. The UE may decode the SSB based at least in part on the SSB configuration. Numerous other aspects are described.

Abstract: A method, an apparatus, and a computer program product for wireless communication are provided. The apparatus initiates a call attempt in an internet protocol multimedia subsystem (IMS) based on a dialed number, the dialed number including an emergency number. The apparatus receives a session initiation protocol (SIP) message in response to the call attempt. The apparatus determines in response to the SIP message whether to retry the call attempt as a normal call in a circuit-switched (CS) domain for an operator or as an emergency call in the CS domain for the operator. In an aspect, the determining is based at least in part on either an indication in the SIP message or on a characteristic of the operator.

Abstract: Channel estimation at a user equipment includes estimating channel quality of at least one channel. A first algorithm or a second algorithm is selected based on the estimated channel quality. Channel estimation is performed based on the selected algorithm. The first algorithm may be a midamble multiplication-based algorithm. The second algorithm may be a midamble division algorithm. Channel estimation may also include estimating noise of a channel and adaptively setting a threshold based on the estimated noise to refine the channel estimation. The estimating channel quality, selecting of a first or second algorithm and channel estimation may be performed iteratively for contributing signals on a channel. An adaptive threshold may be modified across iterations. The channel estimation may also include determining a delay profile of a channel to refine the channel estimation.

Abstract: Techniques for synchronizing an emulated wireless communication device over a local link are disclosed. In one aspect, the emulating device (106) monitors received signals for information directed to the emulated device (106). The information is delivered to the emulated device over the local link. In another aspect, the emulated device updates stored information (270) with the information received over the local link. In yet another aspect, a previously emulated device accesses a wide area network directly, using synchronized information. Various other aspects are also presented. These aspects have benefits including keeping an emulated device synchronized with a wide area network such that post-emulation access attempts are made with updated information and parameters.
