Abstract: Electronic devices may be provided that contain wireless communication circuitry. The wireless communication circuitry may include radio-frequency transceiver circuitry coupled to multiple antennas. An electronic device may alternate between a sleep mode and a wake mode. During wake mode, the electronic device may monitor a paging channel in a wireless network for incoming paging signals. The device may use a selected one of the multiple antennas in monitoring the paging channel. If received signal quality is satisfactory, the device may maintain use of the selected one of the multiple antennas for subsequent wake period monitoring of the paging channel. If received signal quality falls below a threshold or is otherwise indicated to not be satisfactory, the device may switch to use of a different one of the multiple antennas in monitoring the paging channel. Other criteria may also be used in controlling the switching between antennas for paging channel monitoring.

Abstract: Manipulating modulation and coding scheme (MCS) allocation after a communication interruption. A UE device may resume communications with a BS after a communication interruption. First channel quality information may be generated and transmitted to the BS. A first MCS allocation, which may be based at least in part on the first channel quality information, may be received from the BS. Second channel quality information may be generated and transmitted to the BS, where the second channel quality information is modified by an offset configured to modify a second MCS allocation.

Abstract: Electronic devices are be provided that contain wireless communication circuitry. The wireless communication circuitry includes radio-frequency transceiver circuitry coupled to first and second antennas. An electronic device sends network access probe signals to a base station in a wireless network. If the base station responds with a corresponding acknowledgement, the electronic device and base station establish a wireless communication link such as a cellular telephone link. In response to failure to receive the acknowledgement signal from the base station, the electronic device increases the transmit power of a successive network access probe signal. The electronic device switchs between use of the first and second antennas when transmitting the network access probe signals. The electronic device alternates between the first and second antennas or uses other antenna usage patterns.

Abstract: Methods and apparatus for adaptively adjusting receiver operation for e.g., power optimization. In one embodiment, operation during diversity operation is adaptively adjusted. Diversity techniques consume significantly more power than non-diversity operation. However, the performance gain from receiver diversity is not always predictable. Consequently, in one embodiment, a device evaluates the overall performance gain contributed by diversity operation and, where the performance gain is insignificant or inadequate, the device disables diversity operation. In one implementation, the device can operate in a static single antenna mode, a dynamic single antenna mode and a dynamic multiple antenna mode.

Abstract: Mobile devices, base stations, and/or relay stations may implement a method for an improved and reliable automatic repeat request feedback indication. A mobile device (UE) may establish communication within a wireless network, and indicate to the network that the UE is a special type device, e.g. a constrained device. The network (base station) may then not send an indication on a physical indicator channel to the UE when certain conditions are met, and instead, the mobile device may interpret control information received from the network on a physical control channel as a negative acknowledgment indication corresponding to an automatic repeat request from the network. The UE may then perform a retransmission according to the interpreted control information. A new control information format may be used to further define how the network and UE implement the automatic repeat request process, to reduce the total number of bits required in the control information.

Abstract: Enhanced random access procedures for link-budget-limited user equipment (UE) devices are disclosed. A user equipment device may transmit a first message containing a Physical Random Access Channel (PRACH). The PRACH contains instances of a Zadoff-Chu sequence, and may be transmitted repeatedly as part of a single random attempt, to facilitate correlation data combining at the base station. The available Zadoff-Chu sequences may be partitioned among a plurality of sets, each set being associated with a respective Doppler shift range (or frequency hop pattern or time repetition pattern). A UE device may signal Doppler shift (or other information) to the base station by selection of one of the sets. The first PRACH transmission and the following PRACH transmission may occur in consecutive subframes. A UE device may select from a special set of Zadoff-Chu sequences (different from a conventional set of sequences), to signal its status as a link-budget-limited device.

Abstract: Mechanisms for operating a wireless user equipment device, to determine the state of data scheduling activity. Such activity state (and other information such as measurements of signal interference and/or channel condition) may be used to dynamically control the selection of a high-power high-performance receiver vs. a low-power basic receiver. A first mechanism involves transitioning to a high activity state and starting a timer upon each occurrence of scheduled subframe. A transition to the low activity state occurs whenever the timer expires. A second mechanism involves filtering a sequence of binary-valued indicators corresponding respectively to a sequence of time intervals. Each indicator indicates whether a subframe is scheduled during the corresponding time interval. The filter output is compared to a threshold to determine high/low activity state. The temporal width of the filter impulse response may be increased to support fast initial response without harming the accuracy of activity-state determination in the steady state.

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: Managing radio resources across dual networks includes a wireless mobile device connecting to a first wireless network using a first radio access technology. The wireless device may notify the first network of a capability to be temporarily non-responsive to the first network while maintaining a signaling connection to the first network. The wireless device may communicate with a second network. The wireless device may return to communicating with the first network subsequent to communicating with the second network, and in response to communicating with the second network for less than a predetermined amount of time, the wireless device may send a scheduling request to the first network. In response to receiving a grant acknowledgement from the first network, the wireless device may send a buffer status report that includes a value such as zero to indicate that the wireless device has returned to and can communicate with the first network.

Abstract: Apparatus and methods for implementing "intelligent" receive diversity management in e.g., a mobile device.. In one implementation, the mobile device includes an LTE-enabied UE, and the intelligent diversity management includes selectively disabling receive diversity (RxD) in that device upon meeting a plurality of criteria including (i) a capacity criterion, and (it) a connectivity criterion. In one variant, the capacity criterion includes ensuring that an achievable data rate associated with a single Rx (receive) chain is comparable to that with RxD.
