Abstract: Methods, systems, and devices for wireless communications are described that provide for a user equipment (UE) to report packet switched voice call capabilities to a base station. The UE may explicitly report voice call capabilities via one or more system-level parameters that are transmitted to the base station. The base station may operate in a first radio access network (RAN), such as a 5G or new radio (NR) RAN. In cases where the UE indicates a capability for packet switched voice calls via the first RAN, one or more voice calls may be established with the UE via the first RAN. In cases where the UE indicates that it is not capable of packet switched voice calls via the first RAN, the UE may fall back to a different RAN (e.g., a 4G or LTE RAN, a 3G RAN, or a 2G RAN) for voice calls.

Abstract: Coverage enhancements and coverage mode switching related optimizations are discussed for user equipments (UEs) that may switch between various coverage extension (CE) and non-CE modes of operation. In such enhancements, paging uncertainty and delays may be reduced by sending pages either simultaneously or using historical information over multiple coverage modes available to UEs. Random access procedures may be improved by providing CE mode random access procedures that are available when normal mode random access attempts fail and before declaring radio link failure. Additional aspects include improvements for more advanced UEs to improve coverage within normal mode operations by leveraging techniques used for narrowband CE mode operations, including transmission repetition and gapless transmission scheduling over hopped narrowband frequencies.

Abstract: Extended DRX (e-DRX) operation using hyper frame extension signaling are described. The hyper frame extension signaling may extend the system frame number (SFN) range while maintaining backward compatibility for legacy devices not configured to use the extended SFN range. The hyper-SFN extension signaling may include an index to a hyper-SFN transmitted as part of system information different than that used for transmission of the SFN. UEs configured to use the hyper-SFN may effectively use a longer or extended SFN range that includes the legacy SFN range and the hyper-SFN range. The hyper-SFN extension may be used in an extended idle DRX (eI-DRX) mode which may coexist with existing I-DRX mode on the same paging resources. Additionally or alternatively, paging may be differentiated for eI-DRX mode UEs using separate paging occasions or a new paging radio network temporary identifier (RNTI).

Abstract: Systems and methodologies are described that facilitate notifying and detecting modification of system information in a wireless communication system. A mobile device may detect an inability to receive a paging message transmitted by a base station during a first time period, receive at least one system information block (SIB) transmitted by the base station during a second time period, and determine whether to receive one or more additional SIBs transmitted by the base station in the second time period based on information obtained from the at least one SIB received. The mobile device may detect an inability to receive a paging message upon entering a cell from being out of service or upon initial device starting up. The mobile device may determine whether to receive one or more additional SIBs by comparing a value tag of the at least one SIB received to a previously stored value tag.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment concurrently communicates with a source base station (BS) and a target BS on a connection with the source BS and a connection with the target BS as part of a make-before-break (MBB) handover procedure; and performs a common packet data convergence protocol (PDCP) function for the connection with the source BS and the connection with the target BS before the connection with the source BS is released as part of the MBB handover procedure. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described that provide for a user equipment (UE) capability indication that indicates one or more constraints associated with a supported modulation order. In some cases, the UE capability indication may indicate that the UE supports a particular modulation order, but has a capacity constraint such that an associated data rate is limited to a data rate associated with a lower modulation order. In some cases, one or more frequency bands may be mapped to a UE constraint.

Abstract: Methods, systems, and devices for wireless communications are described. A base station may configure a secondary component carrier (CC) for a user equipment (UE) which is not aligned on a valid channel raster entry. The location of the secondary CC may be indicated based on a reference location relative to another frequency or another CC. The reference location of the secondary CC may be the center of the new CC, an edge of the secondary CC, the position of a subcarrier within the secondary CC, or the position of a resource. In some examples, the reference location of the secondary CC may be indicated relative a currently used CC, an arbitrary channel entry, or an absolute frequency location. In some examples, the relative location may be provided in resource blocks or subcarriers and the subcarrier spacing (SCS). The base station may indicate the width of the secondary CC to the UE.

Abstract: Methods, systems, and devices for wireless communication are described that provide for identification, on a per-PLMN basis of a type of core network associated with each PLMN in a list of networks associated with a base station. A user equipment (UE) may receive the list of networks and, based at least in part on the type(s) of core network accessible via each PLMN and a capability of the UE, initiate a connection establishment with a PLMN and associated core network. In some cases, UEs that are not capable of connections with a first type of core network (e.g., a 5G core network) may be restricted from camping on a cell or PLMN that may provide only connections with the first type of core network (e.g., a 4G core network).

Abstract: Methods, systems, devices, and apparatuses are described for wireless communications in which a wireless device may identify a small cell (e.g., SCell) and establish an independent connection with the small cell based at least in part on selection parameters received from a macro cell (e.g., PCell). The selection parameters may include power and/or quality parameters, as wells as a set of candidate cells from which to make the selection. The macro and small cells may be in communication with each other but need not be associated with the same base station (i.e., are not collocated). Once the small cell connection is established, the device may communicate with both cells concurrently. Available uplink data and/or downlink data may trigger the need for the device to connect with the small cell. For example, the small cell connection may be used to communicate uplink/downlink data associated with certain quality-of-service (QoS) and/or bearer identifier.

Abstract: A delta configuration is transmitted to a UE requesting a handover wherein the delta configuration details changes that are required for the current UE configuration in order to execute the handover. The handover is initiated via a measurement report transmitted to a currently serving source eNode B from the UE. The measurement report can comprise one or more of current radio conditions, current UE configuration or a preferred target eNode B if the handover is a inter eNode B handover. In a inter eNB handover, the current UE configuration is forwarded to the preferred target eNode B by the source eNode B. The target eNode B generates the delta configuration and transmits it to the source eNode B in a transparent container which is subsequently forwarded to the UE.
