    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 (MB) 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: A user equipment device (UE) 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 UE may use physical channels and procedures (e.g. it may receive and decode control channels) in a manner compatible with and not infringing on the operation of other UEs operating in the same network, while allowing the network more flexibility to assign resources. Specifically, resources for EPDCCH on UE-specific SS and EPDCCH on common SS may be shared. That is, the resources for two search spaces may be overlaid partially or in full, giving the network more flexibility in allocating resources. Furthermore the DCI formats for MPDCCH may be extended to devices operating according to the new device category, which enables the coverage enhancement of MTC for these devices.

    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 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: Providing a power-saving mode for control channel monitoring in discontinuous reception (DRX) scenarios. Upon waking from a sleep mode at the conclusion of a DRX off period, a baseband modem may transition to a low-power mode configured to receive and decode only a control channel, such as a physical downlink control channel (PDCCH). If the control channel indicates during a DRX on period that communication traffic will be transmitted to the baseband modem, then the baseband modem may transition to a full-power mode to receive the communication traffic. Otherwise, the baseband modem may transition back to the sleep mode. The low-power mode may be implemented by a dedicated set of hardware configured to draw less power than a full set of hardware configured to implement the high-power mode.

    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.
