Abstract: Embodiments described herein relate generally to a communication between a user equipment (UE) and an evolved Node B (eNB). An eNB may allocated uplink and downlink regions associated with machine-type communication (MTC) to a UE. The allocation of uplink and downlink regions may be asymmetric. The eNB may identify parameters based on this asymmetric region allocation to avoid resource collision during communication of hybrid automatic repeat request (HARQ) acknowledgement (ACK) or negative acknowledgement (NACK) feedback between the eNB and the UE. Other embodiments may be described and/or claimed.

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.

Abstract: Narrowband Physical Downlink Control Channel (PDCCH) implementations are discussed. An example Evolved NodeB (eNB) comprises a memory storing instructions, a processor configured to execute the instructions, and a transmitter circuit. The processor is configured to determine at least one of downlink or uplink scheduling for one or more machine-type communication (MTC)-enabled user equipments (UEs); to generate, based at least in part on the determined scheduling, one or more MTC-physical downlink control channel (PDCCH) signals (M-PDCCH signals) associated with the one or more MTC-enabled UEs; and to perform channel coding, multiplexing, and scrambling of the one or more M-PDCCH signals. The transmitter circuit is configured to map the one or more M-PDCCH signals to resource element groups (REGs) in order of increasing subcarrier followed by orthogonal frequency division multiplexing (OFDM) symbol and to transmit the one or more M-PDCCH signals via a narrowband bandwidth of less than 1.4 MHz.

Abstract: Wireless mobile devices or user equipments (UEs) may communicate directly with other UEs, e.g., using device-to-device (“D2D”) direct discovery and communication. D2D direct discovery and communication may be used, for example, when UEs communicate with each other while within direct wireless range of each other. Different service types for D2D direct discovery and communication sessions, such as public safety (PS) services, non-PS services, etc., may utilize different data characteristics for the discovery message (e.g., data types and data structures). Data associated with the at least one data frame of a D2D direct discovery transmission can be configured to indicate these different data characteristics.

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.
