Abstract: Technology for a user equipment (UE) operable to identify downlink control channel candidates for receiving downlink control channel information is disclosed. The UE can decode a downlink control information (DCI) format received from an eNodeB. The DCI format can indicate a set of resource blocks (RBs) in one or more subframes allocated for reception or transmission of data or control information in a shortened transmission time interval (S-TTI). The UE can identify a subset of resource elements (REs) within the set of RBs in the one or more subframes. The subset of REs can correspond to shortened physical downlink control channel (S-PDCCH) candidates in the S-TTI of one or more subframes. The UE can attempt to decode the S-PDCCH candidates in the S-TTI of the one or more subframes. S-PDCCH candidates that are successfully decoded can cause the UE to identify the downlink control information.

Abstract: An eNodeB (eNB), Machine Type Communications (MTC) user equipment (UE) and method using a physical uplink control channel (PUCCH) in a non-legacy PUCCH region are generally described. The UE may be in an enhanced coverage (EC) mode. The UE may receive higher layer signaling indicating physical resource blocks in the PUCCH region and offsets in a cell- or UE-specific manner on a per-slot basis or, when in EC mode, per-set of N subframes basis. The UE may receive a resource allocation for a PUCCH in a PUCCH region separate from a legacy PUCCH region and reserved for non-legacy UEs. The UE may transmit a frequency hopping PUCCH in the PUCCH region and use shortened PUCCH format to accommodate an extended retuning time by puncturing a first and/or last symbol of at least one slot. If retuning, the UE may drop a sounding reference signal transmission in the next subframe.

Abstract: An apparatus of a user equipment (UE) may include a memory and one or more processors operatively coupled to the memory device. The processors determine a reporting mode for the UE based on a message received at the UE from an eNodeB. The UE may generate a channel state information (CSI) reporting message based on the determined reporting mode. The processors may also encode extra-large physical uplink control channel (xPUCCH) data including the CSI reporting message.

Abstract: Embodiments of an Evolved Node-B (eNB), User Equipment (UE), and methods for flexible duplex communication are generally described herein. The eNB may transmit a downlink control information (DCI) block to the UE during a group of time-division duplex (TDD) sub-frames. The eNB may further receive an uplink control information (UCI) block from the UE during the group of TDD sub-frames. A first candidate flexible duplex format for the TDD sub-frames may include a downlink control portion and an uplink control portion. A second candidate flexible duplex format for the TDD sub-frames may include a downlink control portion and may exclude uplink control portions.

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×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: Downlink control information techniques for wireless communications with shorter TTI (S-TTI) length are disclosed. An apparatus of a user equipment (UE) can include processing circuitry configured to decode signaling indicating a duration of a time window, the time window comprising a plurality of S-TTIs forming a single TTI. Absence of a discontinuous reception (DRX) indicator is detected within control information received within a first S-TTI of the plurality of S-TTIs. Upon detecting the absence of the DRX indicator within received control information, a S-PDCCH within each of the plurality of S-TTIs is monitored during the duration. Scheduling information received via the S-PDCCH within one of the plurality of S-TTIs is decoded, and data is encoded for transmission on a shared data channel based on the scheduling information.
