    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 a master information block (MIB), a first system information block (SIB), and second SIBs. The first SIB and the second SIBs may be configured for different device categories, and may accordingly have different characteristics. For example, the first SIB may be configured for link budget limited devices, and may include information specific to such devices and/or may exclude information not relevant to such devices or not critical to accessing the cell. In some instances, the first SIB may also include information from the MIB, such that at least some devices may be able to decode the first SIB and gain cell access without decoding the MIB.

    Abstract: A user equipment (UE) and base station may implement improved communication methods which enable a UE that is peak current limited to perform UL transmissions which are consistent with the UL timeline. A UE that is peak current limited may utilize a new form of distributed TTI (transmit time interval) bundling for improved uplink communication performance. In performing “distributed” TTI bundling, the UE may transmit a plurality of redundancy versions of first information to the base station, wherein the plurality of redundancy versions are transmitted in non-consecutive sub-frames with a periodicity of X ms. After the plurality of redundancy versions of first information are transmitted to the base station, the base station may provide a single acknowledge / negative acknowledge (ACK/NACK) to the UE. A method for dynamically generating and using a bundle size for TTI bundling is also disclosed.

    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: Systems, apparatuses, and methods for coverage improvements in wireless communication devices. A wireless communication device may be configured to selectively receive one of a plurality of paging signals, or a portion thereof, based on measured or expected coverage quality of communications from a base station. In some scenarios, the wireless communication device may provide an indication to the base station of which paging signal the wireless communication device will attempt to receive, such that the base station may include paging information directed to that UE only in the indicated paging signal. In some scenarios, the base station may include paging information directed to that UE in a plurality of paging signals, each of the paging signals including a different number of repetitions of the paging information. In some scenarios, the UE may receive only a portion of a paging signal including a plurality of repetitions of the paging information.

    Abstract: A wireless communication system is presented for future scheduling of secondary component carrier(s) (SCC) during carrier aggregation in LTE wireless communications. A primary component carrier in a first subframe can be used to indicate at what future subframe SCC data may exist for the mobile device (e.g., UE, etc.). The UE can then leave off all SCC receive circuitry until the future subframe, when it can turn on all needed SCC receive circuitry to receive the SCC data. After receiving the SCC data, the UE can again power off the SCC receive circuitry.

    Abstract: In some embodiments, a user equipment device (UE) implements a method for discovering the presence of neighboring UEs using an on-demand discovery signal transmission technique. This discovery process may be performed to enable the UEs to perform peer-to-peer communications with each other, wherein peer-to-peer communications is defined as direct communication between the UEs without involving a base station. The UE may be configured to transmit a discovery request signal when it has moved greater than a threshold amount since transmission of a prior discovery request signal. The discovery request signal causes one or more neighboring UEs to each transmit a discovery signal in response, and also causes the UE which generated the discovery request signal to transmit its own discovery signal. The received discovery signal from each of the neighboring UEs is useable to discover, or detect the presence of, these neighboring UEs.
