Abstract: A user equipment (UE) device may communicate according to a new device category satisfying specified QoS (quality of service) requirements while also satisfying specified link budget requirements, and/or additional optimization requirements. The UE device may communicate with a cellular base station according to a first mode of operation associated with the new device category, and may switch to communicating with the cellular base station according to a second mode of operation associated with a second (pre-existing) device category in response to the link budget requirements exceeding a specified value and the quality of service requirements not being sensitive. The UE device may also switch to communicating with the cellular base station according to a third mode of operation associated with a third (pre-existing) device type in response to the link budget requirement not exceeding the specified value, or the QoS requirements being sensitive and a downlink throughput requirement exceeding a specified throughput value.

Abstract: A wireless communication device (UE) may include a paging subsystem that performs paging-monitoring as part of wireless communications of the wireless communication device. The UE may place wireless communication system resources not required during paging-monitoring into either a low-power state or a power-down state, and those system resources may remain in one of those respective states during paging-monitoring. The wireless communication system resources not required during the paging-monitoring may include at least a wireless communications protocol stack used during the wireless communications of the UE, and at least system resources used for performing uplink related tasks independently of wireless communication system resources used for performing downlink related tasks. The paging subsystem may include at least a control manager subsystem capable of decoding a physical downlink control channel, a downlink control subsystem capable of performing tasks related to a physical downlink data channel, and a message parser for parsing paging messages.

Abstract: A user equipment (UE) device may communicate according to a new device category satisfying specified QoS (quality of service) requirements while also satisfying specified link budget requirements, and additional optimization requirements. The new device category may identify the UE device as a wearable device. According to some embodiments, LTE category M may be extended to support non-MTC operations performed by wearable devices. For example, the new device category may support UE mobility and may disallow access barring. Additional extensions may be implemented in response to an indication by the UE that the UE is implementing a specific application, such as VoLTE or a near real-time application, such as audio streaming. In some scenarios, the indication may include the UE indicating a specific QCI value. In some scenarios, the indication may include the UE attaching to a specific APN.

Abstract: This disclosure relates to providing system information for cell access to link budget limited devices. According to some embodiments, a base station may transmit an announcement information block (AIB) in a downlink shared data channel (e.g., PDSCH), wherein the AIB contains information useable by a UE in determining the location of system information in the downlink shared data channel. The UE can thus determine the location of and decode system information without having to decode a downlink control channel (e.g., PDCCH). This may be important for certain classes of devices, such as link budget limited devices, which have issues in decoding the downlink control channel. Improved paging scheduling techniques are also disclosed which more efficiently use PDCCH paging resources.

Abstract: In some embodiments, a wireless device such as a user equipment (UE) may communicate with a base station using an advanced form of carrier aggregation. The UE may provide signaling to the network specifying a number P of downlink component carriers to be configured for use by the UE for downlink carrier aggregation and a number Q of uplink component carriers to be configured for use by the UE for uplink carrier aggregation. The UE can only utilize a lesser number M of downlink component carriers at any given time in downlink carrier aggregation and can only utilize a lesser number N of uplink component carriers at any given time in uplink carrier aggregation. Thus the UE may request the network to configure a greater number P and Q of downlink and uplink component carriers, respectively, than the UE can actually use at any instant of time.

Abstract: For paging user devices that are link budget limited (LBL), a base station transmits a special ID that is used by said devices to identify a paging frame and/or a paging occasion. When transmitting a paging message for an LBL device, the base station may use: (a) larger aggregation and larger CFI (than conventionally allowed) and (b) a larger number of resource blocks (than conventionally allowed) for paging payload. If paging messages for LBL devices saturate the paging frame capacity, the base station may allocate a plurality of special IDs. If paging messages for LBL devices and/or other data transfers saturate network capacity, at least a subset of the LBL devices may be directed to enter a connected-state discontinuous reception (DRX) mode, wherein those devices will remain in connected mode and periodically check for resource allocations. Paging payload information may be repeatedly transmitted in successive subframes, to support soft combining.

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: An apparatus, system, and method for performing PDCCH preparation in RF circuitry are described. In one embodiment, power may be provided to a crystal oscillator to exit a first sleep state. One or more clocking signals may be provided to RF circuitry based on output from the crystal oscillator. Calibration and state restoration of the RF circuitry may be performed independent of baseband circuitry. A plurality of algorithms to prepare for receiving data form a wireless communication network may be performed independent of the baseband circuitry. After initiating the plurality of algorithms, state restoration of the baseband circuitry may be performed. Data may be received from a wireless communication network using the RF circuitry. The data may be processed using the baseband circuitry. State retention for the RF circuitry and the baseband circuitry may be performed. Finally, the crystal oscillator may be powered down to enter a second sleep state.
