Abstract: Techniques are described herein for fast and efficient discovery of small cells by user equipment (“UE”) in a wireless telecommunications network. The small cells may operate at a high frequency band (“HFB”), which may correspond to higher frequencies than other cells (e.g., base stations, such as evolved Node Bs (“eNBs”)) of the network. The UE may receive assistance information, which may include polling channel configurations, beamforming weights, carrier frequencies, cell identifiers of small cells, and/or other information. The UE may use the assistance information when outputting (either omnidirectionally, pseudo-omnidirectionally, or directionally) a polling sequence, in order to detect the small cells.

Abstract: Embodiments of beamformed physical downlink control channel (B-PDCCH) are generally described herein. A user equipment (UE) decodes an indication of a transmission mode for a beamformed physical downlink control channel (B-PDCCH) received from a network entity. The UE decodes one or more symbol blocks corresponding to a downlink (DL) control region of a subframe, wherein the DL control region includes one or more control clusters, and wherein one discrete Fourier transform (DFT) spreading window is applied in each of the one or more control clusters. The UE determines a B-PDCCH search space according to the indicated transmission mode, wherein the B-PDCCH search space is a set of B-PDCCH candidate locations. The UE performs blind decoding of one or more B-PDCCHs based on the determined B-PDCCH search space, to obtain downlink control information transmitted from one or more evolved NodeBs (eNBs) to the UE via the one or more B-PDCCHs.

Abstract: A user equipment (UE) can process signals including a first synchronization signal (SS) and a second SS. The first SS and the second SS are beamformed with transmit beams and transmitted on subbands in a first set of symbols, for the first SS, and a second set of symbols, for the second SS. The UE can detect the first SS in the first set of symbols, and measure beam qualities of the transmit beams on the subbands in at least one of the first set of symbols or the second set of symbols. The UE can select one or more transmit beams and corresponding one or more subbands based on the measured beam qualities. The UE can detect the second SS on the selected subbands in the second set of symbol, and each of subbands in the first and second sets of symbols is associated with a transmit beam.

Abstract: Technology for a base station operable to encode guard interval (GI) discrete Fourier transform (DFT) spread orthogonal frequency-division multiplexing (OFDM) (GI-DFT-s-OFDM) data symbols for transmission to a user equipment (UE) is disclosed. The base station can identify GI-DFT-s-O 5 FDM data symbols for transmission to the UE. The base station can encode the GI-DFT-s-OFDM data symbols for transmission to the UE in a subframe. The subframe can be in accordance with a flexible subframe structure that begins with a demodulation reference signal (DMRS) sequence followed by a GI sequence in a first symbol of the subframe. The subframe can further comprise one or 10 more subsequent symbols in the subframe that each include a GI-DFT-s-OFDM data symbol followed by a GI sequence.

Abstract: Disclosed herein are apparatuses, systems, and methods using or implementing dynamic beamforming in control channels, by transmitting downlink control channels to user equipment (UEs) in a number of orthogonal frequency division multiplexing (OFDM) symbols of a downlink subframe. A first OFDM symbol of the number of OFDM symbols can be transmitted using first beamforming parameters in a first direction, and a second OFDM symbol of the number of OFDM symbols can be transmitted using second beamforming parameters different from the first beamforming parameters and in a second direction different from the first direction. The number of OFDM symbols used, as well as other parameters, can be dynamically adjusted in subsequent subframes. Other embodiments are described.

Abstract: An architecture configured to be employed within one or more user equipments (UEs). The architecture includes a communications array and a control component. The communications array is configured to receive one or more reference signals of one or more reference signal ports of a subframe. The reference signals are analog beamformed cell-specific reference signals associated with one or more cells. The control component is configured to decode the received reference signals and perform analog beam tracking and demodulation based on the one or more received reference signals.

Abstract: Systems and methods for enhancing spectral efficiency are disclosed herein. User equipment (UE) may be configured to communicatively couple to an Evolved Universal Terrestrial Radio Access Network (E-UTRAN) Node B (eNB). The UE may be configured to cancel interference from an interfering eNB. The interfering eNB may provide transmission parameters to the UE. The interfering eNB may transmit a compact message indicative of the transmission parameters to the UE. The compact message may be a broadcast message. Some transmission parameters may be sent to the UE using higher layer signaling. The UE may be able to use the transmission parameters to cancel interference from the interfering eNB. In some embodiments, the interfering and/or serving eNB may indicate to the UE whether the transmission parameters are being broadcast so the UE does not search for them unnecessarily.
