Abstract: Aspects of the disclosure relate to reporting and correcting a spatial misalignment of an orbital angular momentum (OAM) waveform communicated from a second device to a first device. In an aspect, the first device receives from the second device, the OAM waveform having a spatial misalignment with respect to the second device. The first device determines the spatial misalignment and further determines spatial coordinates for correcting the spatial misalignment and/or one or more channel measurements of the OAM waveform. Thereafter, the first device sends a report based on the spatial misalignment to the second device, the report including the spatial coordinates for correcting the spatial misalignment and/or the one or more channel measurements. The first device then receives an adjusted OAM waveform from the second device, wherein the adjusted OAM waveform is received having a corrected spatial alignment with respect to the second device based on the report.

Abstract: Methods, systems, and devices for wireless communications are described. Generally, the described techniques provide for flexible selection of a type of mapping to use for mapping code blocks to a set of resources for transmission. A user equipment (UE) may transmit assistance information to a base station to assist the base station in selecting from a set of mapping types available for code block mapping. The UE may then receive, from the base station, an indication of a selected mapping type for code block mapping based on the assistance information. The assistance information may include a recommendation of a mapping type or a metric of a channel that the base station may use to select the mapping type. Because the mapping type may be selected dynamically (e.g., “on the fly”), the UE and the base station may be able to adaptively exploit different types of diversity.

Abstract: Wireless communication techniques for supporting, selecting, and using multiple waveforms and/or multiple decoders for downlink wireless communication are discussed. A UE may transmit to a base station an indication of one or more downlink waveforms or decoders supported by the UE. The UE may also transmit to the base station an indication of power consumption associated with at least one of the one or more downlink waveforms or decoders. The UE may receive from the base station an indication of a waveform or decoder, based on the indication of power consumption, to use for downlink wireless communication.

Abstract: Aspects are provided which allow for a base station to transmit code blocks according to a frequency first per layer (FFPL) mapping, and for a UE to decode received code blocks according to the FFPL mapping. The base station maps a plurality of code blocks to multiple layers, where each of the code blocks is mapped to a plurality of resource elements initially by frequency and subsequently by time on only a single layer of the multiple layers. The base station then transmits data including the code blocks to a UE. Afterwards, the UE receives the data including the mapped code blocks in multiple layers from the base station, and the UE decodes the code blocks based on the mapping. Thus, improvements in link efficiency, reliability, and reduced power consumption compared to frequency first (FF) mapping approaches may be achieved.

Abstract: This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for mapping coding indices associated with a rateless coding scheme to respective sets of communication resources over which a transmitting device may perform transmissions of portions of a message corresponding to each of the coding indices. In some aspects, for example, different coding indices may correspond to different cumulative portions of the message and the transmitting device may transmit a first cumulative portion of the message corresponding to a first coding index over a first set of communication resources to which the first coding index is mapped. The transmitting device may signal an indication of such a resource mapping scheme to a receiving device and the receiving device may attempt to decode transmissions of one or more cumulative portions of the message using the indicated resource mapping scheme.

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 SRS configuration may define the temporal spacing between repetitions of the SRS. The base station may indicate the SRS configuration to the UE so that the UE transmits repetitions of the SRS according to the SRS configuration. 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: Certain aspects of the present disclosure provide a technique for wireless communications by a user equipment (UE). The UE implements the technique to detect that a decoding failure of a first multiple input multiple output (MIMO) transmission, sent by a network entity on a first number of layers, is caused by a rank mismatch. The UE then sends a rank correction request to a network entity. The UE then combines samples from the first MIMO transmission and a second MIMO transmission, sent by the network entity using a space-time code (STC) with a second number of layers in response to the rank correction request, to recover data lost due to the decoding failure.
