Abstract: Techniques are disclosed relating to broadcasting and receiving system information in a radio access network (RAN). In one embodiment, a base station includes at least one antenna, at least one radio, configured to perform cellular communication using a radio access technology (RAT), and one or more processors coupled to the radio. In this embodiment, the base station is configured to broadcast first system information blocks (SIBs) encoded using a first coding rate and a first identifier. In this embodiment, the base station is also configured to broadcast second SIBs encoded using a second coding rate that is lower than the first coding rate and a second identifier. In this embodiment, the second SIBs include only a portion of the information included in the first SIBs and the second SIBs are usable by user equipment devices (UEs) having a limited link budget to determine access parameters for the base station.

Abstract: This application presents techniques for an LTE user equipment (UE) to use an extended service request (ESR) extension for LTE TDD to FDD redirection for mobile originated and mobile terminated VoLTE calls. These techniques include the UE informing the network that it supports the particular features of the ESR extensions presented. Once the UE attaches to the network, a radio resource control (RRC) message can be sent to indicate that the UE supports the new ESR extension, after which the UE can use the new ESR extension to facilitate an LTE TDD to FDD redirection for the VoLTE call.

Abstract: Methods and apparatus for suspending session state during hybrid network operation. In one exemplary embodiment, a cellular device uses a single-radio solution to support circuit-switched calls on a CDMA 1× network and packet-switched calls on LTE. Periodically, the cellular device tunes away from LTE and monitors CDMA 1× activity, and vice versa. During these tuned-away periods, the client device may suspend operation on the tuned away network for extended tune away intervals.

Abstract: Methods and apparatus for network-based detection and mitigation of hybrid client device reception outage events. For example, in one embodiment, a cellular device uses a single-radio solution to support circuit-switched calls on a CDMA 1X network and packet-switched calls on LTE. Periodically, the cellular device tunes away from LTE and monitors CDMA 1X activity, and vice versa. During these tuned-away periods, the network adjusts operation to mitigate adverse effects (e.g., underutilization of radio resources, synchronization loss, etc.).
