    Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive broadcast information from a base station indicating a numerology or a reference signal (RS) pattern to be used in broadcast or multicast transmissions (e.g., a physical multicast channel (PMCH)). The UE may identify a modulation and coding scheme (MCS) associated with the broadcast or multicast transmission and may determine a transport block size (TBS) based on the MCS and at least one of the numerology or the RS pattern. For instance, a UE may determine TBS for numerologies associated with a single symbol that spans multiple subframes differently from that of other numerologies. Additionally or alternatively, a UE may determine TBS for sparse RS patterns differently from that of other RS patterns. The UE may then perform communication with the base station via the broadcast or multicast transmissions in accordance with the TBS.

    Abstract: The present disclosure relates to methods and devices for a handover procedure which may include a user equipment (UE), first base station, and a second base station. In one aspect, the UE can receive an indication to handover from the first base station to the second base station. The UE may then establish a connection with the second base station. In another aspect, the UE can maintain a connection with the first base station over a period of time during the handover. The UE can also communicate with the first base station and the second base station during the period of time based on a time division multiplexing (TDM) pattern. The TDM pattern can comprise a pattern of subframes for communicating with the first and second base station. In another aspect, the UE can release the connection with the first base station at the end of the period of time.

    Abstract: Methods, systems, and devices for wireless communications are described to improve support for broadcast systems. In some wireless communications systems, such as broadcast systems for a multimedia broadcast/multicast service (MBMS), an inter-site distance between transmitters or between a transmitter and a receiver may be relatively large compared to an inter-site distance for other scenarios of a wireless communication system (for example, cellular data or talk scenarios). A transmitter in a broadcast system may adjust one or more characteristics of resources in a frame, such as the subframe structure, slot structure, or symbol structure, in carriers dedicated for MBMS resource transmissions. For instance, the transmitter may adjust durations of one or more symbols in a frame.

    Abstract: In aspects of the disclosure, a method, an apparatus, and a computer program product for wireless communication are provided. In one aspect, the apparatus determines if a connection to a PLMN has been established. In another aspect, the apparatus builds a FQDN based on the determination by attempting to build the FQDN using each of the prioritized FQDNs in order of priority until the FQDN is built, building the FQDN using a PLMN ID of the PLMN if it is determined that the PLMN is found in the list, or building the FQDN based on the wildcard PLMN if it is determined that the list comprises the wildcard PLMN. Further still, the apparatus selects a network security gateway to provide network security and internet working control based on the FQDN.

    Abstract: Handover parameter settings are automatically adapted in access points in a system to improve handover performance. Reactive detection techniques are employed for identifying different types of handover-related failures and adapting handover parameters based on this detection. Messaging schemes are also employed for providing handover-related information to access points. Proactive detection techniques also may be used for identifying conditions that may lead to handover-related failures and then adapting handover parameters in an attempt to prevent such handover-related failures. Ping-ponging may be mitigated by adapting handover parameters based on analysis of access terminal visited cell history acquired by access points in the system. In addition, configurable parameters (e.g., timer values) may be used to detect handover-related failures.

    Abstract: Enabling Ethernet Header Compression (EHC) for use with data sent within a Non-Access Stratum (NAS) control plane of a wireless communication network. In one aspect, a wireless communication device sends a signal to a wireless communication network indicating the device supports EHC for data transfer over a control plane. The device obtains a response from the wireless communication network indicating the wireless communication network supports EHC for data transfer over the control plane. The device then sends an Ethernet packet compressed using EHC to the wireless communication network over the control plane. The wireless communication device may be configured to send a request to the wireless communication network to use EHC before sending the Ethernet packet compressed using EHC. The device then sends the compressed Ethernet packet only if the request is granted. In another aspects, complementary EHC features are provided within a network component of the wireless communication network.

    Abstract: Methods, systems, and devices for wireless communications are described in which paging messages may provide an indication of a service that caused the page, and a receiving user equipment (UE) may determine a paging response based on a UE status and the service that caused the page. The paging response may include ignoring the page, a paging response with a busy indication, or a paging response after a time delay, for example. The paging message may be received at an access stratum (AS) layer of the UE, and the AS layer may provide the paging message to a non-access stratum (NAS) layer along with the indication of the service that caused the page. The NAS layer may determine the paging response.

    Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a source base station (BS), an indication that the UE is to perform a conditional handover from the source BS to a target BS and is to perform at least one of: a two protocol stack handover from the source BS to the target BS or a dual connectivity handover from the source BS to the target BS. The UE may perform the conditional handover and at least one of the two protocol stack handover or the dual connectivity handover based at least in part on the indication. Numerous other aspects are provided.

    Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may determine a UE capability for available radio access technologies. The UE may determine which of the available radio access technologies are suitable for idle cell reselection (e.g., inter-radio access technology idle cell reselection, intra-radio access technology idle cell reselection) according to the UE capabilities, which may be related to a UE category or UE usage mode (e.g., voice centric mode, data centric mode) of the UE, etc. The UE may transmit a signal indicating the UE capabilities to a network entity (e.g., a serving cell). The network entity may receive the signaling and determine suitable radio access technologies for the idle cell reselection, and transmit a set of parameters in a message for the UE to use as part of the idle cell reselection.
