Abstract: Certain aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may camp on a cell of a first radio access technology (RAT). The UE may perform a cell search for a second RAT while camped on the cell of the first RAT, wherein the second RAT operates in a non-standalone mode with the first RAT. The UE may present, for display, an indication of whether the second RAT is available in the cell based at least in part on performing the cell search for the second RAT. Numerous other aspects are provided.

Abstract: Methods and apparatuses for serving cell management of a user equipment (UE) are presented. Particularly, methods and apparatuses are presented for suppressing a serving cell change based on a speed of the UE. For instance, an example method is presented for serving cell management that may include determining that a serving cell change condition exists for an initiation of a serving cell change for the UE, wherein the serving cell change comprises changing a serving cell of the UE from a macro cell to a low power cell. In addition, the example method may include obtaining a speed of the UE and suppressing the initiation of the serving cell change based on the speed of the UE.

Abstract: Certain aspects of the present disclosure relate to methods and apparatus for transitioning between short DRX and long DRX cycles based on service type to improve performance (e.g., reduce delay) while limiting power consumption. In one example, the UE switches to a long DRX cycle after a DRX Short Cycle Timer, or drxShortCycleTimer, expires. The UE may also switch to a long DRX if the UE receives long DRX MAC control element (CE) from a gNB. In another example, a gNB may configure a radio bearer from a set of radio bearers (data radio bearer (DRB) and/or signal radio bearer (SRB)), denoted by S, to trigger the UE to enter a short DRX cycle.

Abstract: Certain aspects of the present disclosure provide techniques for per-flow jumbo maximum transmission unit (MTU) in new radio (NR) systems. A method of wireless communication by a user equipment (UE) is provided. The method generally includes determining a default MTU size to be used for communications in a packet data network (PDN). The method includes determining one or more per-flow MTU sizes, different than the default MTU size, to be used for communications in the PDN. The method includes communicating in the PDN according to the determined per-flow MTU sizes.

Abstract: Methods, systems, and devices are described for concurrently performing handoff-related measurements for neighbor cells using multiple input multiple output (MIMO) antenna resources. In one example, a mobile device is in communication with a serving cell. Handoff-related measurements of first wireless signals from a first neighbor cell are performed. The first wireless signals are received at first MIMO antenna resources of a device. Handoff-related measurements of second wireless signals from a second neighbor cell are performed, as well. The second wireless signals are received at second MIMO antenna resources concurrently with the first wireless signals received at the first MIMO antenna resources. The first handoff-related measurements and the second handoff-related measurements may be performed during a scan interval. A type of handoff-related measurement to perform may be determined based on a determined length of the scan interval.

Abstract: Methods, systems, and devices for wireless communications are described for providing local broadcasts for group calls. A user equipment (UE) may request a group call, and either a base station or a local server dedicated to the base station may determine whether to allow the group call based at least in part on an assessed level of interest for the group call. If the group call occurs, the UE may perform one or more aspects of user plane processing for the broadcast data—such as setting Internet protocol (IP) addresses in IP packets, encryption, compression, or media formatting—and may transmit the broadcast data to the base station. The base station may then transmit the broadcast data to one or more interested UEs via one or more multicast transmissions without routing the broadcast data through other network nodes, which may reduce latency and provide other benefits.

Abstract: Wireless communications systems and methods related to providing an indication that a user equipment (UE) is within coverage by a particular network are provided. An example method of wireless communications obtaining, by a first wireless communication device from a second device associated with a second network, information regarding whether the first wireless communication device is within coverage by a first network. The first wireless communication device supports dual connectivity with the first network and the second network. The method also includes determining, based at least in part on the information, whether to display an icon indicating that the first wireless communication device is connected to the first network. The method further includes in response to a determination to display the icon, displaying, by the first wireless communication device, the icon on a display coupled to the first wireless communication device.

Abstract: A method, an apparatus, and a computer program product for wireless communication enable user equipment operating in a current cell that provides a multimedia broadcast/multicast service to distinguish between neighboring cells that have different operational characteristics. The presence of a neighboring cell is identified while the user equipment is operating in a first cell and it is determined whether the neighboring cell provides services different from the services provided in the current cell, based on information maintained by the user equipment. The user equipment may move to the neighboring cell to obtain better or different service.

Abstract: Various embodiments include multi-subscription multi-standby (MSMS) communication devices and methods for managing reception of data using a first subscription following a tune-away by a radio frequency (RF) resource chain from the first subscription to a second subscription. In various embodiments the MSMS communication device may receive data over the first subscription during a warm-up period of the RF resource chain following completion of the tune-away. In some embodiments, the device processor may receive the data over the first subscription during the warm-up period using one or more channel parameters of the first subscription determined before the tune-away. In some embodiments, the device processor may receive data over the first subscription during the warm-up period using one or more channel parameters of the first subscription determined initially during the warm-up period.

Abstract: Embodiments described herein relate to systems and methods for scheduling subscriptions in a user equipment (UE) having at least a first receive radio and a second receive radio, including receiving, by the first receive radio, a broadcast activity for a first subscription and receiving, by the second receive radio, a reception activity for a second subscription. A trigger event is detected while the broadcast activity for the first subscription is being received by the first receive radio and the reception activity for the second subscription is being received by the second receive radio. In response to detecting the trigger event, the reception activity for the second subscription is received by the first receive radio and the broadcast activity for the first subscription is received by the second receive radio.
