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.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a wireless communication device may receive an encoded communication, the encoded communication being encoded with a hierarchical coding scheme comprising: first layer code blocks including pairs of information bits and sets of first parity bits, and second layer code blocks including sets of second parity bits, with each set of the second parity bits associated with a subset of the first layer code blocks. The wireless communication device may decode the encoded communication based at least in part on one or more of the sets of the second parity bits that are associated with one or more of the first layer code blocks determined to have failed decoding based at least in part on one or more associated sets of the first parity bits. Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communications are described. A wireless device may apply phase precompensation to multiple user-multiple input multiple output (MU-MIMO) communications with different wireless devices. The wireless device may measure one or more axis offsets between antenna arrays of the wireless device and other antenna arrays of different wireless devices. The wireless device may perform MU-MIMO communications with the different wireless devices by applying phase precompensation according to the axis offset. For example, the wireless device may transmit or receive communications from multiple wireless devices using the phase precompensation.

Abstract: Methods, systems, and devices for wireless communications are described. A base station may determine to enable orbital angular momentum (OAM) beamforming for communications with a user equipment (UE), for example, based on one or more communications parameters and receiving a message from the UE indicating a capability of the UE to use OAM beamforming. The base station may transmit control signaling to the UE indicating that OAM beamforming is enabled. In some examples, the base station may transmit control signaling indicating an OAM configuration, which may be for a same slot in which the control signaling is transmitted or a subsequent slot. The base station may transmit a downlink transmission to the UE via OAM beamforming. In some examples, the base station may estimate and correct misalignment associated with OAM beamforming. In some examples, the base station may disable OAM beamforming and transmit an indication that OAM beamforming is disabled.

Abstract: Methods, systems, and devices for wireless communications are described. Generally, the described techniques provide for a base station to transmit a feedback configuration to a user equipment (UE) indicating a subcarrier spacing and a length of a cyclic prefix (CP) that the UE is to use to transmit feedback associated with a second frequency band (e.g., a high frequency band) using a first frequency band (e.g., a low frequency band). The UE may monitor the second frequency band for downlink messages transmitted by the base station and transmit a feedback message accordingly using the indicated subcarrier spacing and applying a CP having the indicated length.

Abstract: Aspects relate to beam management in multi-stream communication between a radio access network (RAN) entity and a user equipment (UE). The RAN entity may transmit a plurality of transmit beams from a plurality of transmission and reception points (TRPs) associated with the RAN entity to the UE. For each of the transmit beams, the UE may obtain a beam quality metric on each of a plurality of receive beams of the UE during a measurement period (e.g., in parallel or serially) to generate a respective beam quality metric vector for each of the transmit beams. The UE can then transmit a beam report including the respective beam quality metric vector for each of the transmit beams to the RAN entity. The RAN entity may then select at least two beam pair links, each associated with a respective TRP, for spatial division multiplexing of at least two streams to the UE based on the beam report.
