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 an eNB to operate in accordance with a coverage enhancement mode are disclosed herein. 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: Embodiments of circuitry to be included in a user equipment (“UE”) and an evolved Node B (“eNB”) are described. To accelerate the detection of one or more cells in a wireless network, a UE may perform Radio Resource Management (“RRM”) measurements based on one or more synchronization signals instead of based on a common reference signal (“CRS”). Alternatively, the UE may perform RRM measurements for a cell based on a CRS transmitted for the cell without synchronizing to the cell using one or more synchronization signals. The UE may report the RRM measurements to an cNB that is to serve the UE.

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: A machine type communication (MTC) device is configured to communicate through a long term evolution (LTE) network. 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: Techniques are described for compressing the PUCCH resources reserved for acknowledging downlink data transmissions when those resources are implicitly signaled by EPDCCHs that schedule the downlink transmissions in TDD mode. An acknowledgment resource offset field transmitted in the EPDCCH is configured to correspond to one or more values that compress the region in PUCCH resource index space that would otherwise be reserved for the subframes of a bundling window.
