Abstract: Methods, systems, and devices for wireless communications are described. A receiving device and a transmitting device may utilize index modulation for full-duplex operations. The transmitting device, such as a base station or a user equipment (UE), may define blocks of resource elements (REs) for transmissions. The transmitting device may then transmit a power boosted index modulated signal at a data RE location within a resource allocation and may skip transmitting within the remaining REs of the resource allocation. The transmitting device may indicate the number of REs per RE block to the receiving device (e.g., a UE). The receiving device may use this information to perform energy detection for determining which REs within an RE block include the power boosted index modulated transmission and which REs within the RE block are empty REs. In some cases, the receiving device may use the empty REs for performing noise estimation.

Abstract: Methods, systems, and devices for wireless communications are described. A base station may determine the subcarrier spacing and carrier frequency used by a user equipment (UE) for communicating with the base station. The base station may select a sounding reference signal (SRS) configuration for the UE that is based on the subcarrier spacing and carrier frequency used by the UE.

The base station may measure the SRS repetitions from the UE to determine the Doppler frequency for the uplink channel. The base station may use the uplink Doppler frequency to select a demodulation reference signal (DMRS) configuration for the UE.

Abstract: Methods, systems, and devices for wireless communications are described. Generally, the described techniques provide for transmitting data signaling via a first set of subcarriers (e.g., data subcarriers) at a same transmit power as PTRS transmissions via a second set of subcarriers (e.g., PTRS subcarriers) via a first transmission layer. Additionally, the described techniques provide for transmitting data signaling via the first set of subcarriers and the second set of subcarriers via a second transmission layer. That is, a wireless device may transmit data signaling via the second transmission layer at subcarriers used for PTRS transmissions via the first transmission layer while maintaining an average energy across the first transmission layer and the second transmission layer. In some examples, a receiving device may estimate the phase noise error for each transmission layer using one or more PTRS transmissions or using signaling from each transmission layer.

Moreover, the device phase shifts the signals output from the output ports via a plurality of phase shifters respectively coupled to the output ports. The phase shifted signals have further varying phase shifts relative to each other and a phase difference between adjacent phase shifted signals. Each one of a plurality of antenna elements at the device receives a phase shifted signal from an associated phase shifter and outputs a beam based on the phase shifted signal received from the associated phase shifter.

Abstract: This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for equalization domain selection at a wireless device. A wireless device may be configured to support a selection between time domain equalization and frequency domain equalization for receiving RF signals, which may be performed in accordance with detected channel conditions. For example, if a wireless device detects conditions associated with a relatively dispersive channel, the wireless device may select a frequency domain equalization and, if the wireless device detects conditions associated with a relatively flat channel, the wireless device may select a time domain equalization. In some implementations, performing a time domain equalization may include changing a sampling rate into a symbol rate, such as performing a resampling using a Farrow resampler.
