Abstract: Embodiments of latency reduction for wireless data transmission are generally described herein. A user equipment (UE) identifies a shortened transmission time interval (xTTI) length configuration for a time division duplexing (TDD) component carrier (CC), the xTTI length configuration comprising a length in time or a length in orthogonal frequency division multiplexing (OFDM) symbols. The UE identifies scheduling timing and hybrid automatic repeat request (HARQ) timing of physical downlink shared channel (PDSCH) and physical uplink shared channel (PUSCH) on the TDD CC based on the identified xTTI length configuration. The UE signals for transmission of a HARQ acknowledgement (HARQ-ACK) based on the identified xTTI length configuration.

Abstract: Future LTE systems will support massive carrier aggregation that necessitates transmission of a large number of acknowledgement signals (HARQ-ACKs) in response to downlink data transmitted over multiple component carriers. Described herein are methods and apparatus for efficiently transmitting HARQ-ACK and periodic channel state information (P-CSI) bits over the PUCCH (physical uplink control channel).

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 of wireless communication devices and methods for device discovery is generally described herein. Some of these embodiments describe an apparatus having processing circuitry arranged to configure a single-tone discovery signal for transmission in a symbol in a transmission opportunity based on an assignment pattern. The assignment pattern may define frequency positions, for a set of transmission opportunities, at which the apparatus shall transmit discovery signals in the corresponding transmission opportunity. The apparatus may have physical layer circuitry arranged to transmit the single-tone discovery signal in the corresponding transmission opportunity. Other methods and apparatuses are also described.

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: Embodiments of an enhanced node B (eNB) and methods for network-assisted interference cancellation with reduced signaling in a 3GPP LTE network are generally described herein. In some embodiments, the number of transmission options is reduced by introducing a smaller signaling codebook. In some embodiments, higher-layer feedback from the UE to the eNodeB is established to inform the eNB about certain NA-ICS capabilities of the UE. In some embodiments, the number of signaling options is reduced by providing only certain a priori information. In some embodiments, correlations in the time and/or frequency domain are exploited for reducing the signaling message. In some embodiments, differential information is signaled in the time and/or frequency domain for reducing the signaling message.

Abstract: User equipment (UE), an enhanced NodeB (eNB) and method of reducing handover latency are generally described. The UE may transmit measurement feedback to the eNB based on control signals. The UE may receive a reconfiguration message from the eNB or another eNB to the UE is attached. The reconfiguration message may contain reconfiguration information indicating whether or not a physical layer or layer 2 of the UE is to be reconfigured and/or a security key is to be updated. The reconfiguration information may be dependent on whether the handover is between eNBs controlled by a same entity and/or whether the handover comprises an intra-frequency transition. The UE or eNB may initiate handover of the UE. During handover the UE may avoid physical layer or layer 2 reconfiguration or the security key update. The security key and data for the UE may be provided directly between the eNBs.
