Abstract: The disclosure describes procedures for including downlink control information (DCI) within a physical downlink shared channel (PDSCH) communication to reduce power consumption for a user equipment (UE) operating in a Long Term Evolution (LTE) network. A network apparatus can be configured to identify an expected DCI change for the UE, determine whether an LTE subframe location for the DCI change is known, generate either a general or a specific DCI change indicator, and send the corresponding DCI change indicator to the UE on the PDSCH. The specific DCI change indicator can include a bitmap identifying a particular upcoming LTE subframe where the UE is required to decode the PDCCH for DCI, and the general DCI change indicator can include a bit flag identifying a time associated with one or more upcoming LTE subframes when the UE should decode the PDCCH for DCI.

Abstract: Methods and apparatus for synchronizing operational state during hybrid network operation. In one embodiment, the various access technologies that makeup the hybrid network not fully synchronized. Thus, a wireless device operating in a mixed mode must be capable of managing synchronization across multiple access technologies. The wireless device is configured to estimate an expected “tune-away” period when disengaging with a one access technology to address events (for example, link maintenance, calls, data, and the like) or perform monitoring on a second access technology. The estimate is then used by the device to adjust its operational parameters on the technology from which it is tuning away. This ensures smooth switching away from and back to the various network technologies.

Abstract: A wireless user equipment (UE) device may include a receiver and transmitter. The UE device may dynamically vary the fidelity requirements imposed on the analog signal processing performed by the receiver and/or the transmitter in response factors such as: amount of signal interference (e.g., out-of-band signal power); modulation and coding scheme; number of spatial streams; extent of transmitter leakage; and size and/or frequency location of resources allocated to the UE device. Thus, the UE device may consume less power on average than a UE device that is designed to satisfy fixed fidelity requirements associated with a worst case reception scenario and/or a worst case transmission scenario.

Abstract: This disclosure relates to aggregation of radio resources provided according to multiple radio interfaces. According to some embodiments, a base station may establish a radio bearer with a wireless user equipment (UE) device. The radio bearer may initially utilize a first radio interface between the base station and the UE. The base station may receive an indication to aggregate radio resources of an access point that utilizes a second radio interface for the UE. Based on the indication to aggregate radio resources for the UE, the base station may redirect at least a portion of data of the radio bearer by way of the access point to be exchanged with the UE using the second radio interface.

Abstract: Techniques are disclosed relating to informing a network that a UE desires packet-switched voice communication. In one embodiment, a method includes receiving first information from a UE device requesting voice communication over a packet-switched network. In this embodiment, the method further includes transmitting, in response to the first information, second information to a base station serving the UE device, wherein the second information indicates that the UE device is requesting voice communication over the packet-switched network. In this embodiment, the transmitting is performed prior to establishment of a dedicated bearer by the base station for the UE device. In this embodiment, the second information operates to configure communications between the base station and the UE device to provide a particular quality of service for the packet-switched voice communication using the dedicated bearer.
