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: In embodiments, apparatuses, methods, and storage media may be described for distinguishing, by a user equipment (UE), a reference signal (RS) transmitted by a cell that may have a same identifier (ID) as another cell in a network. In embodiments, a muting pattern, a time offset, or a virtual cell identifier (VCID) may be used to generate an RS sequence or RS resource allocation.

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: 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: Devices and methods of using xSS are generally disclosed. A UE receives an xPSS with (Nrep) symbols each with a subcarrier spacing of K x a PSS subcarrier spacing and a duration of a PSS symbol/K. PSD subcarriers surround the xPSS and the ZC sequence is punctured to avoid transmission on a DC subcarrier. Guard subcarriers separate the xPSS and PSD when the ZC sequence is less than the occupied BW of the xPSS and at least one element in the ZC sequence is punctured for xPSS symbol generation otherwise. One or more xSSSs and xS-SCHs may follow the xPSS. The xSS may be omnidirectional, each having a same xPSS and different xSSS or xS-SCH or a different xPSS and same xSSS or xS-SCH or beamformed, each having different xPSSs and xSSSs or xS-SCHs or a same xPSS and different xSSS or xS-SCH.

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: An enhanced NodeB (eNB), user equipment (UE) and communication methods therebetween using an unlicensed channel of an unlicensed band are generally described. The eNB measures an interference power level (IPL) of the unlicensed channel at the eNB and determine a transmit power level (TPL) for a downlink transmission based on the IPL, the TPL decreasing with increasing IPL. Feedback including unlicensed channel conditions measured by the UE is used by the eNB to determine the UE-eNB proximity. The eNB determines whether to transmit the downlink transmission to the UE based on the IPL and the proximity; as the IPL increases, the eNB services increasingly proximate UEs until, when the IPL exceeds a predetermined threshold, the eNB does not service any UE using the unlicensed channel. The eNB schedules and transmits the downlink transmission to the UE using the transmit power level.

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.
