    Abstract: In an example method, a user equipment (UE) of a wireless network determines data for transmission between the UE and a base station (BS) of the wireless network; determines a context of the transmission of the data between the UE and the BS; selects, based on the context, one or more antenna elements of an antenna array of the UE; and forms one or more wireless beams using the one or more selected antenna elements. Further, the UE (i) transmits at least a first portion of the data to the BS using the one or more wireless beams, and/or (ii) receives at least a second portion of the data from the BS using the one or more wireless beams.

    Abstract: Techniques for a link budget limited UE to improve communications performance with cellular networks are disclosed. The UE may be associated with subscriptions to multiple carriers and may connect to a cell of a first carrier. The UE may detect that received signal strength from the cell is below a threshold and search for a new cell that may be of a different carrier. The UE may store a PLMN eSIM priority look up table and the search may be based on the look up table. Additionally, the UE may track received signal strength and geographic location in a first data structure that the UE may send to a server. The UE may receive a second data structure from the server that includes received signal strength at geographic locations compiled from a plurality of UEs, including the UE. The UE may also use the second data structure in searches for a new cell.

    Abstract: Apparatuses, systems, and methods for user equipment (UE) devices to perform a postponement of a data service request are described. A UE may detect a data service request failure during cell reselection and postpone a resend of the data service request based on a status of the cell reselection. The status may be an indication that the UE is attempting to camp on a cell or that the UE is monitoring one or more metrics associated with cell reselection. To postpone the data service request, the UE may postpone the data service request for a specified period of time or until the cell reselection is complete. The status may be monitored on a first layer of a protocol stack and the data service request may generated by a second layer of the protocol stack. The postponement may be for a fixed or variable time period.
