Abstract: Technology for a user equipment (UE) operable to identify downlink control channel candidates for receiving downlink control 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: Technology for a user equipment (UE) to perform reduced transmission time interval (TTI) data transmission within a wireless communication network is disclosed. The UE can process a process, for transmission to an eNodeB, control information within a short transmission time interval (TTI) over a short resource block (RB) set within a short physical uplink control channel (S-PUCCH), wherein the short TTI is shorter in time than a TTI that has a duration of at least one (1) millisecond, and wherein the S-PUCCH is a subset of resources available for a short physical uplink shared channel (S-PUSCH) and the S-PUSCH is a subset of resources available for a legacy PUSCH transmission; and process, for transmission to the eNodeB, data within the short TTI over the short TTI RB set within the S-PUSCH.

Abstract: Technology for a user equipment (UE) operable to perform blind decoding for one or more beamformed physical downlink control channels (B-PDCCHs) is disclosed. The UE can receive, from one or more transmission points (TPs), one or more symbols corresponding to a downlink (DL) control region of a subframe, wherein the DL control region includes a plurality of control resource blocks (CRBs). The UE can determine a B-PDCCH search space that includes a set of candidate B-PDCCH locations. The candidate B-PDCCH locations can be included in the DL control region of the subframe. The UE can perform blind decoding on the candidate B-PDCCH locations included in the B-PDCCH search space in order to obtain downlink physical control information transmitted from the one or more TPs to the UE via the one or more B-PDCCHs.

Abstract: Technology for a user equipment (UE) configured for communication of sounding reference signal (SRS) resources is disclosed. The UE can decode a radio resource control (RRC) signal indicating an SRS to transmit with a physical uplink control channel (PUCCH), wherein the PUCCH and the SRS are quasi co located (QCLed) based on a spatial received parameter. The UE can encode an SRS for transmission using the spatial received parameter. The UE can encode uplink control information (UCI) for transmission in the PUCCH using the spatial received parameter. The UE can have a memory interface configured to send to a memory the spatial received parameter.
