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.

The eNB may comprise hardware processing circuitry to, during a legacy sub-frame, transmit a system information block (SIB) in legacy SIB frequency resources according to a legacy SIB transmission format and refrain from transmission of channel state information reference signals (CSI-RS). The hardware processing circuitry may be further to, during a first coverage enhancement sub-frame, transmit a first portion of the SIB in first SIB frequency resources included in the legacy SIB frequency resources. The hardware processing circuitry may be further to, during a first coverage enhancement sub-frame, transmit a first set of CSI-RS in first CSI-RS frequency resources that include at least a portion of the legacy SIB frequency resources.

Abstract: Embodiments allow an eNBs and a target UE to both calculate which resource block groups (RBGs) to use to transmit data. Because the RBGs that will contain information of interest can be pre-calculated, there is no need to receive and store all RBGs in the transmitted signal before decoding the signal and identifying which RBGs are of interest to the recipient. This allows receivers to buffer and/or store only those RBGs that will contain received information and discard others. The amount of information that needs to be stored and/or buffered thus is less and can result in receivers with less memory and, hence, lower cost. In order to calculate which RBGs are to be used to transmit and/or receive information, a logical RBG index is first calculated and the logical RBG index is mapped to a physical RBG index.

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.

The MTC device include a wireless transceiver to receive a signal through the LTE network, a soft buffer configured to store a plurality of soft channel bits for up to a maximum number of hybrid automatic retransmission request (HARQ) processes, and a signal processing unit. The signal processing unit is configured to determine a total number of soft channel bits based at least on the maximum number of HARQ processes, and to use limited buffer rate matching (LBRM) to store a reduced number of the total number of soft channel bits in the soft buffer.

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.
