Abstract: User equipment (UE) can include processing circuitry configured to decode radio resource control (RRC) signaling from a base station, the RRC signaling indicating a transmission coding scheme for a physical uplink shared channel (PUSCH) transmission. PUSCH-to-phase tracking reference signal (PT-RS) energy per resource element (EPRE) ratio is determined using the RRC signaling. A PT-RS power boosting factor is determined based on the transmission coding scheme and the PUSCH-to-PT-RS EPRE ratio. The PT-RS is encoded for transmission using a plurality of PT-RS symbols, the transmission using increased transmission power corresponding to the PT-RS power boosting factor. The RRC signaling further includes a flag enabling the PT-RS transmission. The PUSCH-to-PT-RS EPRE ratio is 00 or 01, and the transmission coding scheme is a codebook-based uplink transmission or non-codebook-based uplink transmission.

Abstract: A method to trigger aperiodic CSI reports in LTE TDD systems having dynamic uplink-downlink configurations is proposed. When uplink grants can be sent on any subframe, the method further defines how to indicate which measured subframe set is to be used in reporting the aperiodic CSI. The method is useful for homogeneous networks and networks employing enhanced interference management and traffic adaptation (eIMTA).

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 acknowledgement 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.

Abstract: An enhanced NodeB (eNB), user equipment (UE) and method of communicating using Long Term Evolution (LTE) licensed and unlicensed bands are generally described herein. The eNB may transmit a trigger signal to the UE. The trigger signal may be transmitted in the LTE unlicensed or licensed band and inform the UE of transmission of a reference signal from the eNB to the UE in the unlicensed band. The trigger signal may correspond to a single reference signal transmission or multiple periodic or consecutive reference signal transmissions. The trigger signal or a separate trigger signal may be used to inform the UE of a data transmission. The trigger signal may be transmitted at any point prior to or in the same subframe as the reference signal and the reference signal may be transmitted before, after or in the same subframe as the data.

Abstract: An eNodeB (eNB), user equipment (UE) and method for operating in enhanced coverage (EC) modes are generally described. The UE may receive one or more physical broadcast channel (PBCH) signals, dependent on whether the UE is in a normal coverage mode or in one of the EC modes. The PBCH signal may be combined to form a combined PBCH signal, when the UE is in an EC mode, and decoded to determine one of a plurality of sets of resource regions associated different EC modes for communication with the eNB. The signal may be scrambled using a Radio Network Temporary Identifier (RNTI) dependent on at least one of a signal type of the control signal and the EC mode. Paging and the system information block (SIB) signals in a Physical Downlink Shared Channel (PDSCH) may be decoded without decoding a physical downlink control channel (PDCCH) signal associated with the PDSCH.

Abstract: Technology described herein addresses symmetric uplink (UL)/downlink (DL) designs that can be applied to both uplink and downlink transmissions. A symmetric UL/DL design can define a Transmission Time Interval (TTI) format with control channels and data channels multiplexed using Frequency Division Multiplexing (FDM) or Time Division Multiplexing (TDM) to partition the control channels and the data channels within a Transmission Time Interval (TTI). A unified waveform can be applied to both UL and DL transmissions. Several Demodulation Reference Signal (DM-RS) designs are also described. A hybrid mode for UL transmissions is also described.
