Abstract: Aspects of the disclosure relate to wireless communication including mode division multiplexing of data and reference signals using different orbital angular momentum (OAM) modes. An OAM transmitter may transmit a reference signal (RS) configuration information to an OAM receiver that indicates radio resources for a plurality of OAM modes. The OAM transmitter may further transmit data on a first OAM mode of the plurality of OAM modes using first radio resources of the radio resources indicated by the RS configuration information. The OAM transmitter may further transmit a reference signal on a second OAM mode of the plurality of OAM modes using the first radio resources of the radio resources indicated by the RS configuration information. The OAM receiver may receive the data on the first OAM mode and the reference signal on the second OAM mode. Other aspects, embodiments, and features are also claimed and described.

Abstract: Methods, systems, and devices for wireless communications are described. A first wireless node may transmit, to a second wireless node, an indication of an orbital angular momentum (OAM) base value that is associated with one or more OAM modes. The OAM base value may correspond to a number of antenna elements of an antenna ring at the first wireless node, and for each of the one or more OAM modes. Based on the OAM base value, the first wireless node may communicate reference signaling according to the one or more OAM modes using the number of antenna elements of the antenna ring. The second wireless node may use a same number of antenna elements based on the indicated OAM base value.

Abstract: Methods, systems, and devices for wireless communications are described. Techniques are described herein for encoding downlink control information (DCI) based on the number of transport blocks being scheduled by the DCI. The number of transport blocks supported by the DCI may be indicated explicitly using a field included in the DCI. The number of transport blocks can be implicitly signaled in a bitstream of the DCI block. The type of encoding scheme may be based on the coverage enhancement (CE) mode associated with a user equipment.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a wireless communication device may receive an indication of a first transmit power configuration and a second transmit power configuration for a physical uplink shared channel (PUSCH) communication. The wireless communication device may transmit, using a first transmit power that is based at least in part on the first transmit power configuration, a first portion of the PUSCH communication in a full-duplex portion of a time-frequency resource. The wireless communication device may transmit, using a second transmit power that is based at least in part on the second transmit power configuration, a second portion of the PUSCH communication in a non-full-duplex portion of the time-frequency resource. Numerous other aspects are provided.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may transmit a sounding reference signal (SRS) that indicates that the UE is configured with a quantity of receive elements that is greater relative to a quantity of transmit elements with which the UE is configured. The UE may receive, based at least in part on transmitting the SRS, a first channel state information (CSI) reference signal (CSI-RS) set and a second CSI-RS set. The UE may transmit a CSI report that is based at least in part on the first CSI-RS set and the second CSI-RS set. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may perform channel state information measurements on reference signal transmissions from a base station. The UE may identify a set of cross layer coefficients associated with a set of spatial layers based on the channel state information measurements. The UE may additionally identify a set of precoding coefficients associated with a spatial layer from the set of spatial layers. In some implementations, the set of precoding coefficients may be based on the set of cross layer coefficients. In some examples, the UE may transmit the set of cross layer coefficients and the set of precoding coefficients to the base station.
