Abstract: Aspects of the present disclosure relate to wireless communications and, more particularly, to adjusting how certain types of devices wake up and/or stay awake for broadcast service. A method for wireless communications is provided that may be performed by a user equipment (UE). The method includes receiving a power savings configuration indicating sleep periods during which the UE is scheduled to be unreachable. The method includes determining at least one time, during at least a portion of one of the indicated sleep periods, for the UE to be awake in order to at least one of: receive or discover Multimedia Broadcast Multicast Services (MBMS) user services.

Abstract: Methods and apparatuses are provided for facilitating dynamic measurement power offset adjustments for use in reporting channel quality feedback. A user equipment may generate and send a plurality of channel quality indicator (CQI) values to a base station. The base station determines whether at least some of the received CQI values are outside of an upper or lower threshold value. If at least some of the received CQI values are outside the upper or lower threshold value, the base station can transmit an adjusted measurement power offset to the user equipment. On receipt of the adjusted measurement power offset, the user equipment generates subsequent CQI values using the adjusted measurement power offset.

Abstract: Methods, systems, and devices for wireless communications are described. A network entity (e.g., a satellite) may receive control signaling indicating a discontinuous service coverage at a user equipment (UE). The network entity may transmit coverage assistance information indicating a discontinuous service coverage pattern to the UE. The UE, the network entity, or both may determine one or more parameters for a power saving mode at the UE, such as a duration of an active time, a duration of an inactive time, a duration of a keep alive time, or a combination thereof based on the coverage assistance information. In some cases, the UE may transmit an indication of the power saving mode parameters to the network entity. The network entity may transmit a control message to the UE in accordance with the parameters.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may detect that a timer has expired prior to completing a handover of the UE from a source base station (BS) to a target BS. In some aspects, the UE may selectively declare, based at least in part on detecting that the timer has expired, a radio link failure. Numerous other aspects are provided.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive policy information that specifies radio access technology (RAT) priorities for route selection, including a RAT priority of non-cellular over cellular. The UE may establish access for an application over a route that is selected based at least in part on the RAT priority. Numerous other aspects are described.

Abstract: Techniques are described to support call routing and location for a user equipment (UE) with satellite wireless access to a serving PLMN. The UE sends a Session Initiation Protocol (SIP) INVITE message to a network node, such as a P-CSCF, that includes an indication of satellite access for the UE. In response the network node sends a request to another network node for a cell ID for a fixed cell in which the UE is located. The fixed cell can be independent of satellite radio cells for the serving PLMN. The network node may receive the cell ID for the fixed cell and sends the SIP INVITE message to another network node (e.g., an E-CSCF or LRF) with the cell ID for the fixed cell. The other network node may use the cell ID to route the SIP INVITE message or obtain an approximate location of the UE.

Abstract: The present disclosure relates to a user equipment (UE) dynamically adjusting a non-access stratum (NAS) timer. Specifically, the UE may determine operation in a wideband and support of an extended coverage (EC) restriction. The UE may further identify a duration of a non-access stratum (NAS) timer based on determining operation in the wideband and the EC restriction. The UE may further transmit an access request message to a network entity to trigger a mobility management procedure. The UE may further receive an acceptance message from the network entity indicating an unrestricted or restricted status of the EC restriction. The UE may further apply the duration to the NAS timer based on the acceptance message indicating the unrestricted or restricted status of the EC restriction received from the network entity or a history of EC restrictions of a public land mobile network (PLMN) in a defined geographic area.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may receive a master information block (MIB) including enhancement information associated with an enhanced cell acquisition subframe (CAS) for a cellular broadcast service. The user equipment may receive the enhanced CAS, associated with the cellular broadcast service, based at least in part on the enhancement information associated with the enhanced CAS. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described. A base station may configure an outer coded block which a user equipment (UE) may implement to recover an unsuccessfully decoded transmission. The base station may send, to the UE, downlink control information (DCI) indicating an outer coding scheme for the group of data blocks (e.g., a first data block and a second data block). The UE may monitor for the data blocks and the outer coded block. The UE may decode the data blocks based on the outer coded block and the outer coding scheme. In some examples, the outer code block may be made up of a combination of the first and second data blocks. The UE may use the combination of the outer coded block and one of the data blocks to decode an unsuccessfully decode data block.

Abstract: The present disclosure provides the UE with ePDG information that includes a list of networks that provide ePDG in the area where the WLAN access point is located. In an aspect, the list of networks may include a list of PLMN IDs. By receiving the ePDG information containing the list of networks that provide ePDG in the area where the WLAN access point is located, the UE may be prevented from selecting an incorrect ePDG. In aspects of the disclosure, a method, an apparatus, and a computer-readable medium for wireless communication are provided. In one aspect, the apparatus associates with an access point of a wireless communication network. In another aspect, the apparatus receives, from the access point, ePDG information comprising a list of networks that provide ePDGs in an area of the access point. In a further aspect, the apparatus selects an ePDG based on the ePDG information.
