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: A technology is disclosed for an evolved Node B (eNB). The eNB can determine a set of configuration indication fields numbered 1 to N, included in a downlink control information (DCI) format Y carried on the PDCCH, where N = ⌊ L format ⁢ ⁢ Y M ⌋ , Lformat Y is equal to a payload size of the DCI format Y, and M is a number of bits of each indication field. The eNB can map the DCI format Y onto the PDCCH. The eNB can encode for transmission from to the UE the PDCCH with a cyclic redundancy check (CRC) scrambled by an enhanced interference mitigation and traffic adaptation (eIMTA) Radio-Network Temporary Identifier (RNTI) for the UE.

Abstract: Technology for performing device-to-device (D2D) communications is disclosed. A user equipment (UE) can identify D2D data to be transmitted from the UE. The D2D data can be identified when the UE is in a radio resource control (RRC) idle. The UE can be limited to using a defined resource allocation mode to transmit the D2D data from the UE. A service request procedure can be initiated at the UE. The service request procedure can trigger the UE to perform an RRC connection establishment procedure with an evolved node B (eNB) to switch the UE from the RRC idle mode to an RRC connected mode. The UE can receive an uplink (UL) grant from the eNB for communicating the D2D data from the UE. The UE can send the D2D data using the UL grant provided by the eNB.

Abstract: Described herein are processes related to discovering and establishing suitable multi-hop communication paths for (endpoint) user equipments (UEs). A network-initiated discovery and path selection processes may utilize periodically transmitted reference signals along with optional assistance information. A network node, such an eNodeB, and other relaying-capable nodes, such as relay UEs, may transmit periodic reference signals. Based on these transmitted reference signals and optional assistance information, the relay UEs and/or an endpoint node (e.g., the eNodeB or the endpoint UE) may make a selection decision for previous hop paths for communication. The endpoint UE or the eNodeB may make the selection decision for the end-to-end path in order to provide coverage extension for the end UE using multi-hop transmission paths.

Abstract: In embodiments, apparatuses, methods, and storage media may be described for identifying subframes in a radio frame on which a UE may receive a Physical Downlink Control Channel (PDCCH) or enhanced PDCCH (ePDCCH) transmission. Specifically, the UE may receive multiple indications of uplink/downlink (UL/DL) subframe configurations and identify one or more subframes in which the UE may receive the PDCCH or ePDCCH transmission. The UE may then monitor one or more of the identified subframes and base discontinuous reception (DRX) timer functionality on one or more of the identified subframes.

Abstract: Methods, apparatuses, and systems are described related to mapping special subframes in a wireless communication network. In embodiments, an eNB may assign demodulation reference signals (DM-RSs) and/or cell-specific reference signals (CRSs) to a downlink pilot time slot (DwPTS) of a special subframe responsive to a determined configuration of the special subframe. In embodiments, an eNB may bundle the DwPTS or an uplink pilot time slot (UpPTS) of the special subframe with another subframe for scheduling. In embodiments, a UE may estimate a channel associated with the special subframe based on DM-RSs and/or CRSs transmitted in another subframe. In embodiments, an eNB may exclude the DwPTS from scheduling for certain special subframe configurations if a new carrier type (NCT) is used. In embodiments, an eNB may exclude certain special subframe configurations from use for NCT communications. Other embodiments may be described and claimed.
