    Abstract: Mechanisms enabling link-budget-limited (LBL) devices to more effectively perform random access may include: (1) broadcasting a Physical Random Access Channel (PRACH) configuration index (PCI) reserved for LBL devices; (2) configuring LBL devices to use a PCI that is offset from the conventional PCI of current cell; (3) configuring LBL devices to transmit PRACH messages using an alternative set of subframes, different from conventionally-defined subframe set; (4) configuring LBL devices to transmit PRACH messages on odd frames when the conventional PRACH configuration specifies even frames; (5) configuring LBL devices to generate and use extra PRACH preambles that are not used by non-LBL devices; (6) configuring LBL devices to use group B preambles while non-LBL devices are configured to use group A preambles; and (7) boosting power of a random access response message after an Nth random access failure with preamble conforming to an LBL-reserved pattern of preambles.

    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: Performing data communication using a first radio access technology (RAT) while performing a voice call using a second RAT, using a first radio (e.g., a single radio for cellular communication. The UE may use the first radio to initially perform first data communication using the first RAT. During the first data communication the UE may not be communicating using the second RAT or may not generally maintain a connection to the second RAT. Subsequently, the UE may receive an indication to perform at least one of a mobile originated voice call or receive a mobile terminated voice call using the second RAT. Accordingly, the UE may perform the voice call using the second RAT in response to the indication, using the first radio. Additionally, the UE may perform second data communication using the first RAT during the voice call, using the first radio.

    Abstract: A user equipment (UE) communicating in a wireless communication system may include a primary radio frequency (RF) receive chain (PRFRC) and one or more secondary RF receive chains (SRFRCs). When the UE is to undertake a circuit switched fallback (CSFB) process, the UE may use the one or more SRFRCs to search for candidate 2G/3G cells while in parallel using the PRFRC to wait for an ESR response. The UE may initiate a CSFB process and send an extended service request (ESR) message on a packet-switched network. The UE may monitor for receipt of an ESR response on the packet-switched network using a first RF receive chain, and while monitoring, also acquire an initial circuit-switched network using a second RF receive chain. The UE may start an ESR timer when sending the ESR message, and detect whether the ESR timer expires before the ESR response is received.

The information from the second SIM may include an indication of a serving cell of the second SIM. Alternatively or in addition, the information from the second SIM may include an indication of one or more neighboring cells of the second SIM.

    Abstract: Embodiments described herein relate to an apparatus, system, and method for controlling access to multiple antennas in a mobile device. The mobile device may determine priority among a first protocol stack associated with a first subscriber identity module (SIM) in the mobile device and a second protocol stack associated with a second SIM in the mobile device. The mobile device may lock control of a position of a switch to the first protocol stack based on determining the priority among the first protocol stack and the second protocol stack. The switch may control access to the multiple antennas. Accordingly, the second protocol stack may be unable to modify the position of the switch when control of the switch is locked to the first protocol stack.

    Abstract: Performing data communications by a Dual SIM Dual Active (DSDA) user equipment (UE), while simultaneously conducting two concurrent voice calls. The UE may receive a request to perform data communications while conducting a first voice call on a first radio and concurrently conducting a second voice call on a second radio. The UE may then determine whether one of the voice calls is currently on hold. The UE may perform the data communications using the radio on which the held call is being conducted. The UE may therefore dynamically select available slots from the first radio and the second radio for performing the data communication, based on which of the first radio and the second radio has a voice call that is currently on hold. In some embodiments, the data communications may be performed using a Long Term Evolution (LTE) protocol stack.
