Abstract: Embodiments of user equipment (UE), an enhanced node B (eNB), and methods of signaling for proximity services and device-to-device (D2D) discovery in an LTE network are generally described herein. In some embodiments, the UE receives configuration information for a D2D discovery resource pool of a cell. The configuration information includes an indication that the D2D discovery resource pool has been logically divided into a plurality of sub-discovery resource pools. The UE performs an initial transmission of a discovery signal in a discovery period using a single D2D discovery resource from a first sub-discovery resource pool of the plurality of sub-discovery resource pools. The UE performs a number of additional transmissions of the discovery signal in the discovery period using additional D2D discovery resources from sub-discovery resource pools of the plurality of sub-discovery resource pools other than the first sub-discovery resource pool. Other apparatuses and methods are also described.

Abstract: Embodiments of a User Equipment (UE) to operate in accordance with a physical random access channel (PRACH) are disclosed herein. The UE may comprise hardware processing circuitry to determine a coverage enhancement category for the UE based on downlink channel statistics related to reception of downlink signals at the UE from an Evolved Node-B (eNB) and an uplink-downlink imbalance parameter related to uplink reception at the eNB. The hardware processing circuitry may be further to select, for use in a coverage enhancement mode, a PRACH preamble from a set of candidate PRACH preambles based on the determined coverage enhancement category for the UE. In some embodiments, at least some of the candidate PRACH preambles may span a different number of sub-frames.

Abstract: Methods and apparatus are described for transmitting uplink control information (UCI) over an OFDMA-based uplink. In some embodiments, UCI symbols are mapped to resource elements (REs) in the time/frequency resource grid to maximize frequency diversity. In some embodiments, UCI is mapped in a manner that takes into account channel estimation performance by mapping UCI symbols to those REs that are closest (in terms of OFDM subcarriers/symbols) to REs that carry reference signals.

Abstract: Embodiments of a User Equipment (UE) and methods for packet based device-to-device (D2D) discovery in an LTE network are generally described herein. In some embodiments, UE may be enabled for proximity services and may be configured to receive signaling from an enhanced node B (eNB) indicating resources allocated for D2D discovery. The UE may configure a discovery packet in accordance with a predetermined configuration to have at least a discovery payload and a cyclic-redundancy check (CRC). The discovery payload may include discovery-related content. The UE may be configured to transmit the discovery packet on at least some of the indicated resources for receipt by a receiving UE. In some embodiments, a demodulation reference signal (DMRS) may be selected to indicate a payload size and/or MCS of the discovery packet's payload.
