Abstract: Embodiments of a machine-type communication (MTC) User Equipment (UE) and methods for configuring a MTC UE using an evolved Node B (eNB) are generally described herein. A method for configuring a UE for communication performed by circuitry of an evolved Node B (eNB) may include broadcasting, from the eNB, a physical downlink control channel (PDCCH) transmission on a licensed band, transmitting, from the eNB to the UE, a physical broadcast channel (PBCH) transmission multiplexed with a machine-type communication (MTC) PBCH (M-PBCH) transmission, the M-PBCH transmission including a MTC master information block (M-MIB) in a MTC region of the licensed band, wherein the MTC region includes a subset of frequencies of the licensed band, and transmitting, from the eNB to the UE, a first data transmission on the MTC region in a downlink.

Abstract: An eNodeB (eNB), user equipment (UE) and method for operating in enhanced coverage (EC) modes are generally described. The UE may determine whether or not a physical uplink control channel (PUCCH) signal and an uplink signal allocated to different resources in a particular subframe overlap. The uplink signal may comprise another PUCCH signal or a physical uplink shared channel (PUSCH) signal. The PUCCH signals may comprise a scheduling request or acknowledgement response/retransmission request. The UE may select one of the overlapping signals and transmit the selected signal on a resource allocated to the other signal instead of on a resource allocated to the one of the overlapping signals. The other signal may or may not be transmitted dependent on whether it is a PUCCH or PUSCH signal.

Abstract: Embodiments allow selection of a Discovery signal (DS) used to identify an eNB to a UE receiving the DS. The DS allows the UE to ascertain the existence and/or cell identifier of the eNB. DS comprise a plurality of other signals such as a Primary Synchronization Signal (PSS), a Secondary Synchronization Signal (SSS), a Cell Specific Reference Signal (CRS) and/or a Channel State Information Reference Signal (CSI-RS). A DS occasion comprises a number of subframes where the selected signals that comprise the DS are transmitted. The signals selected for the DS, their characteristics and properties allow a UE to decode the cell identifier. The DS occasion occurs with a designated periodicity.

Abstract: Embodiments of a User Equipment (UE) and an Evolved Node-B (eNB) and methods for random access are generally described herein. As part of a random access procedure, the UE may transmit a physical random access channel (PRACH) preamble in a first portion of PRACH time and frequency resources and may receive a physical downlink shared channel (PDSCH) block that includes a random access response (RAR) to the PRACH preamble. The PDSCH block may be based on a random access radio network temporary identifier (RA-RNTI) associated with the first portion of the PRACH resources. Accordingly, the UE may use the RA-RNTI to determine that the PDSCH block is intended for the UE without usage of physical downlink control channel (PDCCH) blocks for the PDSCH block. In some embodiments, the UE may be configured for machine-type communication (MTC).

Abstract: Techniques for improving observed time difference of arrival (OTDOA) positioning are discussed. One example apparatus employable in an eNB comprises a processor, transmitter circuitry, and receiver circuitry. The processor is configured to: generate a set of positioning reference signals (PRSs); and encode the set of PRSs for a multi-antenna transmission. The transmitter circuitry is configured to transmit the set of PRSs via the multi-antenna transmission. The receiver circuitry is configured to receive a set of reference signal time differences (RSTDs) from a user equipment (UE) in response to the set of PRSs. The processor is further configured to estimate a position of the UE based at least in part on the set of RSTDs.

Abstract: Techniques for observed time difference of arrival (OTDOA) positioning based on heterogeneous reference signals (RSs) are discussed. One example apparatus configured to be employed within a user equipment (UE) comprises receiver circuitry, a processor, and transmitter circuitry. The receiver circuitry can receive, from each of a plurality of evolved Node Bs (eNBs), one or more RSs of each of a plurality of distinct types of RSs. The processor can determine, for each of the eNBs, a time of arrival (TOA) of the one or more RSs of each of the plurality of distinct types of RSs; and compute, for each of the eNBs, a reference signal time difference (RSTD) based at least in part on the TOAs of the one or more RSs of each of the plurality of distinct types of RSs. The transmitter circuitry can transmit the RSTD computed for each of the eNBs.

Abstract: User equipment (UE), an enhanced NodeB (eNB) and method of improving positioning accuracy and enabling vertical domain positioning of the UE are generally described. The UE may receive a prsInfo control signal having at least one PRS configuration and subsequently a plurality of Reference Signals (RSs). The RSs may have a first Positioning Reference Signal (PRS) pattern in a first set of PRS subframes and a second PRS pattern in a second set of PRS subframes received prior to a subsequent first set of PRS subframes. The RSs may have a vertical positioning RS and a lateral positioning RS. The UE may measure PRS resource elements (REs), each having a PRS, in the first and second PRS pattern. The UE may transmit a measurement of the PRS in the first and second PRS pattern. The patterns may enable horizontal and vertical positioning to be determined.
