Abstract: Methods, systems, and devices for wireless communication are described. Generally, the described techniques provide for efficiently facilitating acknowledgment (ACK) or negative acknowledgment (NACK) feedback from a user equipment (UE) for a set of transport blocks in one or more multicast transmissions from a base station. The UE may determine control channel resources for transmitting the ACK/NACK feedback, and each respective control channel resource may correspond to a distinct subset of the set of transport blocks. Once the UE determines a subset of transport blocks that the UE failed to decode (such as at least one transport block), the UE may determine a respective control channel resource that corresponds to the at least one transport block that the UE failed to decode. The UE may transmit ACK/NACK feedback on the respective control channel resource, which, in some examples, may indicate that the UE failed to decode the subset of transport blocks.

Abstract: A first communication device receives a first signal from a second communication device, where a first band used for communication between the first communication device and a third communication device overlaps a second band used for communication between the second communication device and a fourth communication device. The first communication device adjusts a start moment of a first transmission frame of the first communication device or an end moment of the first transmission frame based on the first signal.

Abstract: Methods, systems, and devices for wireless communications are described. Techniques described herein provide for formulating single carrier waveforms into an orthogonal frequency-division multiple access (OFDMA) framework. To fit into the cyclic prefix OFDM (CP-OFDM) grid, a frequency domain fast Fourier transform (FFT) may be applied to the single carrier waveform, a bandwidth expansion and spectrum shaping may be applied to the output of the FFT and inverse FFT (IFFT) processing may be applied to the output of the bandwidth expansion and spectrum shaping. The output of the IFFT may then be represented in an OFDM compatible manner.

Abstract: Methods, apparatus, and systems for efficiently utilizing scattered narrow spectra without introducing interference among adjacent frequency bands are described. In one example aspect, a wireless communication method includes determining a set of time-domain symbols by applying an inverse Fourier transform to a set of processed data modulated on multiple subcarrier groups. Each subcarrier group comprises an even number of subcarriers and adjacent subcarrier groups are separated by one or more unused subcarriers. The set of processed data is determined by applying a first spreading code to data carried in subcarrier groups having 2×m subcarriers when m is a positive odd number and applying one or more spreading codes to data carried in subcarrier groups having 2×n subcarriers when n is a positive even number. The method also includes transmitting the set of time-domain symbols.
