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: 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: This disclosure provides systems, methods and apparatus, and computer programs encoded on computer storage media, for managing communications with a base station by a processor of a wireless device. In one aspect, a processor of a wireless device may receive from the base station a system information change indication in first system information. The processor may determine from the first system information scheduling information of second system information. The processor may determine a factor that a request for the second system information will collide with a request from another wireless device for the second system information. The processor may send the request for the second system information using the determined factor.

Abstract: Various aspects of the disclosure relate to handover of a user equipment (UE) between a standalone mode of operation and a non-standalone mode of operation. For example, a UE may be handed-over from standalone to non-standalone, or vice versa. Moreover, this handover may be an inter-system handover (e.g., between an LTE core network and an NR core network).

Abstract: Methods, systems, and apparatuses for wireless communication are described. A user equipment (UE) may receive information from a network node. The system information may include inter-frequency configuration and measurement reporting configuration. The UE may perform a measurement of a frequency or multiple frequencies that are associated with the inter-frequency configuration. Subsequent to the measurement, the UE may transmit a report of the measurement of the frequency or multiple frequencies to the network node during a radio resource control (RRC) connection procedure based on the measurement reporting configuration.

Abstract: Certain aspects of the present disclosure generally relate to wireless communications, and more specifically to enhanced paging procedures for devices with limited communications resources, such as machine type communication (MTC) devices and enhanced or evolved MTC (eMTC) devices. An example method generally includes determining a set of subframes corresponding to a paging occasion for the UE to receive a paging message from a base station (BS), determining, within the set of subframes, at least one narrowband region for receiving the paging message, and monitoring for the paging message in the at least one narrowband region within the set of subframes.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a message that indicates a change from an evolved universal mobile telecommunications system (UMTS) terrestrial radio access (E-UTRA) packet data convergence protocol (PDCP) to a New Radio (NR) PDCP, wherein the message includes an instruction to perform an intra-cell handover; generate one or more security keys based at least in part on receiving the message that includes the instruction to perform the intra-cell handover; and communicate using the one or more security keys after the intra-cell handover is performed. Numerous other aspects are provided.

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: Confusion resulting from assigning the same node identifier to multiple nodes is resolved through the use of confusion detection techniques and the use of unique identifiers for the nodes. In some aspects an access point and/or an access terminal may perform operations relating to detecting confusion and/or providing a unique identifier to resolve confusion.

Abstract: Methods, systems, and devices for wireless communication are described that provide for sharing or isolating network resources between multiple cells in a system. Resources are allocated to multiple cells and multiplexed according to a time division multiplexing (TDM) scheme where a portion of a component carrier is shared between multiple cells. The allocation of resources also includes splitting or sharing a portion of the time resources between two or more cells such that a subframe is allocated as a subframe shared between multiple cells or as a subframe dedicated for use by only a single cell.
