Abstract: Methods, systems, and devices for wireless communications are described. Techniques described herein provide for a user equipment (UE) with a Modulated Retro Reflector (MRR) to support full duplex Optical Wireless Communications. To achieve full duplex communication, the UE and a network entity may use compatible modulation schemes for downlink communications and uplink communications. The UE and network entity may negotiate and agree upon compatible the uplink and downlink modulation schemes. The UE may receive a downlink OWC transmission using the downlink modulation scheme and transmit an uplink OWC transmission via modulating the downlink transmission in accordance with the uplink modulation scheme.

Abstract: A method of wireless communication by a user equipment (UE) includes reporting, to a base station, a requested downlink code block mapping, which has a defined duration. The method also includes receiving a first code block from the base station during the defined period of time. The method further includes receiving a second code block from the base station during the period of time. The method further includes decoding the first code block with a first demodulator according to the code block mapping. The method still further includes decoding the second code block with a second demodulator, which is different from the first demodulator, according to the code block mapping.

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.

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. Such techniques may include a wireless device selecting an equalization scheme associated with a relatively lowest power consumption for detected channel conditions.

Abstract: Methods, systems, and devices for reporting redundancy version with feedback information. are described. A user equipment (UE) may transmit, to a base station, feedback information corresponding to a code block group in conjunction with an indication of a redundancy version for retransmission of the code block group. The UE may monitor for the retransmission of the code block group based on the indication of the redundancy version for the retransmission of the code block group. The UE may then decode the retransmission of the code block group based on the monitoring and the redundancy version for the retransmission of the code block group.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may monitor for a set of synchronization signals that includes a first subset of synchronization signals allocated according to a first time-frequency pattern and a second subset of synchronization signals allocated according to a second time-frequency pattern different than the first time-frequency pattern. The first subset of synchronization signals and the second subset of synchronization signals are monitored during a first time interval. The UE may receive one or more synchronization signals of the set of synchronization signals based on the monitoring. The UE may establish a connection with a network entity based on receiving the one or more synchronization signals. The UE may receive an indication of the second time-frequency pattern from one or more synchronization signals of the first subset of synchronization signals.

Abstract: Methods, systems, and devices for wireless communications are described. In some implementations, a wireless communications network may support per-beam synchronization signal block (SSB) periodicity configurations. A network entity may transmit, using a first beam, a first SSB associated with a cell supported by the network entity. The first SSB may include a first broadcast channel that indicates a first periodicity for transmission of the first SSB associated using the first beam. In addition, the network entity may transmit, using a second beam, a second SSB associated with the cell supported by the network entity. The second SSB may include a second broadcast channel that indicates a second periodicity for transmission of the second SSB associated with the cell using the second beam. In such cases, the second periodicity may be different from the first periodicity.

Abstract: Methods, systems, and devices for wireless communications are described. A first device, such as a user equipment (UE) or base station, may receive, at a first antenna of a first antenna array, a first set of reference signals. The first device may measure the phase for each of the reference signals and estimate a linear offset between the first antenna array and a second antenna array of a second device that transmitted the reference signals. The first device may adjust an alignment of the first antenna array according to the estimated linear offset. The first device may receive a second set of reference signals, measure the phase for each of the reference signals, and estimate one or more rotational offsets between the first antenna array and the second antenna array. The first device may adjust the alignment of the first antenna array based on the one or more rotational offsets.

Abstract: This disclosure provides systems, methods, and apparatus, including computer programs encoded on computer-readable media, for implementing a power harvesting protocol at a network entity and a channel engineering device (CED) of a wireless communication network. In some aspects, the network entity and the CED may implement a power harvesting protocol that includes power harvesting capabilities and configuration signaling to support power harvesting at the CED. The CED may provide a power harvesting capabilities message to the network entity that includes a parameter that indicates capabilities for power harvesting at the CED. The network entity may respond with a power harvesting configuration message to configure the CED for power harvesting. After configuration of the CED, the network entity may transmit dedicated and non-dedicated (or opportunistic) power harvesting signals to the CED for use by the CED for power harvesting. The dedicated and non-dedicated power harvesting signals may be periodic or aperiodic.
