Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive, from a base station, a channel state information (CSI) configuration indicating a first feedback reporting periodicity for a dominant, or strong, spatial layer and a second feedback reporting periodicity for a non-dominant, or weak, spatial layer. The UE may transmit a first CSI report for at least the dominant spatial layer according to the first feedback reporting periodicity. The UE may transmit a second CSI report for the non-dominant spatial layer according to the second feedback reporting periodicity. In some cases, for aperiodic reporting, the UE may be triggered by downlink control information to report CSI for the dominant spatial layer. In some cases, the CSI configuration may indicate different codebooks for the dominant and non-dominant spatial layers.

Abstract: Methods, systems, and devices for wireless communications are described. In some systems, a device may select antenna elements from a planar array to transmit or receive an orbital angular momentum (OAM) beam. The device may determine a first area (e.g., a first ring area) based on an angular direction over which the device can communicate an OAM beam with a second device and may determine a second area (e.g., a second ring area) on the planar array based on projecting the first area on the planar array. The device may select a set of antenna elements from the planar array that are located within the second area. The device may determine a complex-valued weight for each antenna element of the selected set of antenna elements and may transmit or receive an OAM beam to or from the second device via the set of antenna elements according to the angular direction.

Abstract: Network coding in automatic receipt request (ARQ) functionality is disclosed. A compatible transmitter configures a new transmission period, in which the set of data for transmission is transmitted, and a retransmission period, after the new transmission period, in which a number of network coded data is retransmitted based on the acknowledgement feedback received from the receivers receiving the transmitted set of data. The acknowledgement feedback identifies one or more data requested for retransmission by one or more of the receivers. The transmitter determines a number of network coded data that could be transmitted to accommodate each of the requesting receivers and the data requested by such receivers for retransmission. These network coded data would then be retransmitted by the transmitter during the retransmission period.

Abstract: Methods, systems, and devices for wireless communications are described. Some wireless communications systems may support emergency messaging using a mobile relay. For example, a first user equipment (UE), may transmit a first emergency message indicating a request for relaying a second emergency message to one or more network entities, the first UE being out-of-coverage of a network entity. The first UE may receive, from a second UE associated with an aircraft, a feedback message in response to the first emergency message and may transmit, to the second UE, a second emergency message based on receiving the feedback message. The second UE may receive the second emergency message and transmit, over an air-to-ground wireless communications network, an indication based on the first emergency message and the second emergency message.

Abstract: Methods, systems, and devices for scrambling for probabilistic constellation schemes (PCSs) in wireless communications are described. In some examples, a first wireless device may scramble a set of amplitude information bits associated with a transport block for transmission to a second wireless device. In such examples, the first wireless device may perform a distribution matching procedure on the scrambled set of amplitude information bits. The first wireless device may encode the set of distributed amplitude bits and, in some cases, may perform a modulation procedure on the encoded set of distributed amplitude bits in accordance with a PCS scheme to obtain a codeword associated with the transport block. In some examples, the first wireless device may transmit the codeword to the second wireless device.

Abstract: Aspects of the disclosure relate to the generation of channel state reports and precoding a wireless transmission based on frequency division duplex (FDD) reciprocity. A base station (B S) uses at least two precoders to transmit signals to A user equipment (UE). The UE generates a set of channel state reports, in which the UE transmits a first set of channel coefficients using a first timing, a set of port attributes using a second timing, and a second set of channel coefficients using a third timing. The first set of channel coefficients correspond to a first precoded portion of the wireless transmission, and the set of port attributes and the second set of channel coefficients correspond to a second portion of the wireless transmission. The BS modifies at least one of the precoders based on the channel state reports. Other aspects, embodiments, and features are also claimed and described.

Abstract: Methods, systems, and devices for wireless communications are described. Techniques described herein provide for a user equipment (UE) to share unused antennas dedicated or configured for a one radio access technology (RAT) for communications with a network entity of another RAT. The UE may communicate, via a first set of antennas using a first RAT. The UE may also communicate, via a second set of antennas, using a second RAT. To share the one or more antennas dedicated or configured for the second RAT, the UE may transmit, to the network entity of the first RAT, an indication of a capability to switch the second set of antennas from the second RAT to the first RAT. The UE may communicate with the network entity of the first RAT via the first set of antennas and via the second set of antennas.

Abstract: Methods, systems, and devices for wireless communications are described. A base station may transmit an encoded transmission via a broadcast to multiple user equipment (UE). Subsequently, the multiple UEs may transmit assistance information to the base station based on attempting to decode the broadcasted encoded transmission. If the decoding is unsuccessful for at least one UE, the base station may then transmit an additional encoded transmission via a unicast or multicast message to the UEs that were unsuccessful. Additionally, the base station may transmit configuration information for the multiple UEs to receive the encoded transmissions and to transmit the assistance information. For example, the configuration information may include portion information for how long the encoded transmission is transmitted via the broadcast, via the unicast, when to transmit the assistance information, etc. In some cases, the configuration information may be based on UE metrics of the multiple UEs.

Abstract: Methods, systems, and devices for wireless communications are described. In a wireless communications system. a user equipment (UE) may receive. from a base station, control signaling indicating a quasi co-location (QCL) configuration associated with multiple-input multiple output (MIMO) communications within a distance threshold from the base station. In some cases, the UE may receive. from the base station, an indication of a downlink transmission associated with the QCL configuration within the distance threshold. The UE may select a beam to receive the downlink transmission within the distance threshold based on the QCL configuration. In some cases. the UE may receive multiple repetitions of the downlink transmission using corresponding antenna combining weight configurations, and the UE may determine a beam weight configuration for the beam to receive the downlink transmission based on receiving the multiple repetitions of the downlink transmission.
