Abstract: A method for reducing a peak to average power ratio (PAPR) of an orthogonal frequency division multiplexing (OFDM) signal. A first signal in the frequency domain is processed to generate a second signal by performing a modular permutation on the first signal according to a modular permutation index, and/or by performing a cyclic shift on the first signal according to a cyclic shift parameter. The second signal is then mapped to a number of tones, and transformed into a time-domain signal for transmission. The modular permutation index and/or the cyclic shift parameter are selected so that the signal for transmission has a PAPR that satisfies a predefined PAPR criteria.

Abstract: Measurements and Channel State Information (CSI) feedback are configured using communications between a network and user equipment (UE). The communications includes a first signaling from a network component to the UE indicating one or more reference signal (RS) resource configurations, a second signaling indicating one or more interference measurement (IM) resource configurations, and a third signaling indicating a CSI report configuration, wherein the CSI report configuration indicates a subset of the one or more RS resource configurations and a subset of the one or more IM resource configurations. The UE establishes a RS based measurement according to the subset of the one or more RS resource configurations and an IM according to the subset of the one or more IM resource configurations. The UE then generates and sends to the network a CSI report in accordance with the CSI report configuration and using the RS based measurement and the IM.

Abstract: Methods for wireless communications over a wideband carrier are provided. Time-frequency resources of the wideband carrier within a transmission time interval are divided into multiple time-frequency resource blocks. Each of the time-frequency resource blocks corresponds to a group of contiguous subcarriers of the wideband carrier and orthogonal frequency division multiplexing symbols. Data streams may be scheduled to be transmitted in different time-frequency resource blocks, and may be destined for different user equipments or the same user equipment. Baseband processing operations may be performed on data streams scheduled in different time-frequency resource blocks independently from one another. Separate control channels or one common control channel may be configured for data transmissions in different time-frequency resource blocks.

Abstract: A method for receiving wideband (WB) LTE uplink signals. A base station may signal a first frequency tone assignment to a first user equipment (UE), the first frequency tone assignment scheduling at least a first set of subcarriers allocated to the first UE, subcarriers in the first set of subcarriers being non-contiguous in the frequency domain. Subcarriers in the first set of subcarriers may be interleaved with subcarriers in a second set of subcarriers. The first UE may perform a first single carrier frequency division multiple access (SC-FDMA) uplink transmission over the first set of subcarriers. A second UE may perform a second SC-FDMA uplink transmission, the second SC-FDMA uplink transmission spanning the second set of subcarriers.

Abstract: In a first example embodiment, a control transmission portion of a mmWave communication is received at a user equipment. The control transmission portion is divided into a plurality of control transmission portion sub-regions, each sub-region scheduling a data transmission for a corresponding sub-region of a data transmission portion of the mmWave communication. Then a first of the control transmission portion sub-regions is demodulated and decoded. A receive analog antenna beamforming is armed according to the demodulated and decoded first of the control transmission portion sub-regions. Beamforming is performed on a first sub-region of the data transmission portion of the mmWave communication, the first sub-region of the data transmission portion corresponding to the first of the control transmission portion sub-regions. During the arming and performing, a second of the control transmission portion sub-regions is demodulated and decoded.

Abstract: A method for wireless communications is provided. The method includes transmitting a first signal during a first time interval. The first signal is encoded with a first spreading sequence generated by permutating a root sequence based on a permutation parameter associated with a first index. The method further includes transmitting a second signal during a second time interval. The second signal is encoded with a second spreading sequence generated by permutating the root sequence based on a permutation parameter associated with a second index. The method further includes receiving an indication of either the first index or the second index from a user equipment (UE).
