Abstract: Methods, systems, and devices for wireless communication are described. A base station may configure multiple phase tracking reference signal (PTRS) patterns in a single time interval (e.g., a slot) to improve phase tracking and phase noise estimation. The base station may transmit control signaling indicating multiple PTRS patterns for the time interval, and a user equipment (UE) may monitor for PTRSs in the time interval according to the indicated patterns to estimate a phase for receiving a downlink message from the base station. In some examples, the UE may signal a list of preferred PTRS patterns for the base station to use based on channel conditions. For example, the UE may transmit a report indicating one or more preferred PTRS patterns and a respective quantity of symbols in which the base station is to use each pattern.

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: 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.

Abstract: Methods, systems, and devices for wireless communications are described. For instance, the described techniques support resource offset mapping for multiplexing. Resource offset mapping may refer to the mapping of frequency-domain symbols to different subsets of resources that are offset from each other or separated by gaps. For instance, a first wireless device may map a first set of frequency-domain symbols to a first subset of subcarriers and a second set of frequency-domain symbols to a second subset of subcarriers. A lowest subcarrier of the second subset of subcarriers may be separated by an offset or a gap from a highest subcarrier of the first subset of subcarriers. As a result, at least some distortion experienced on subcarriers in the gap may not spread to other subcarriers, and the reliability and throughput of communications between the first wireless device and a second wireless device may improve.

Abstract: Aspects of disclosure relate to a UE reporting to a gNB time delays and phases of pilot signals received via multiple transmission paths in order for the gNB to pre-equalize a future transmission to the UE. The UE determines a first time delay for receiving a first pilot signal from a gNB via a first path, determines a second time delay for receiving a second pilot signal from the gNB via a second path, and generates a report based on the first time delay and the second time delay. The UE then sends the report to the gNB and receives a multi-TRP signal from the gNB via the first path and the second path, wherein the multi-TRP signal is pre-equalized for transmission based on the report to at least have a same time delay as a shorter one of the first time delay or the second time delay.
