Abstract: The disclosure describes apparatus and methods for including downlink control information (DCI) normally associated with the physical downlink control channel (PDCCH) within a physical downlink shared channel (PDSCH) to reduce power consumption for a user equipment (UE) operating in a Long Term Evolution (LTE) radio resource control (RRC) connected mode. An enhanced NodeB base station can be configured to generate DCI associated with a future downlink resource assignment or uplink grant for the UE on the PDSCH or a physical uplink shared channel (PUSCH), and then include this DCI within the payload of a current PDSCH communication, such that the PDCCH does not need to be decoded by the UE during a time when DCI for future PDSCH communication is included within a current PDSCH.

Abstract: A wireless electronic device having first and second baseband processors is provided. In one suitable arrangement, radio-frequency power splitters and adjustable low noise amplifiers may be form in the receive paths. The use of power splitters allow signals associated with the first and second baseband processors to be received in parallel. In another suitable arrangement, radio-frequency switches are used in place of the power splitters. The states of the switches may be controlled using at least one of the first and second baseband processors. The use of switches instead of power splitters requires that wake periods associated with the first baseband processor and wake periods associated with the second baseband processor are non-overlapping. To ensure minimal wake period collision, a wake period associated with the second baseband processor may be positioned at a midpoint between two successive wake periods associated with the first baseband processor.

Abstract: A transceiver device may include a transmit path that generates a modulated transmit signal based on a baseband signal, and a receive path that receives a receive signal, which is subject to third-order order distortion caused by intermodulation noise resulting from a continuous wave blocker intermodulating with transmit leakage from the transmit path. The transceiver may also include a compensation path that models portions of the transmit path and the receive path, and generates a replica signal representative of the third-order order distortion according to at least a specified function and the modeled portions of the transmit path and the receive path. The compensation path also filters the replica signal and subtracts the filtered replica signal from the receive signal to eliminate the third-order order distortion caused by the intermodulation noise. The filtering of the replica signal may be performed by programmable finite impulse response filters.

Abstract: Electronic devices may be provided that contain wireless communications circuitry. The wireless communications circuitry may include radio-frequency transceiver circuitry coupled to multiple antennas. Signal strength measurements may be gathered using the antennas and corresponding signal strength difference measurements may be produced to reflect which of the antennas is exhibiting superior performing. Information may be gathered relating to the fading environment of the communications circuitry, such as whether the wireless communications circuitry is transitioning between a fast fading environment and a slow fading environment. For example, the wireless communications circuitry may further include a satellite positioning system receiver or an accelerometer, which may be used in gathering the information. The difference measurements may be filtered and compared to antenna switching criteria such as antenna switching thresholds. An antenna switching threshold may be adjusted in real time based at least in part on the gathered information.

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: 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.
