Abstract: Methods, systems, and devices for wireless communications are described. Generally, the described techniques provide for a base station transmitting a modulation and coding scheme index corresponding to a modulation and coding scheme table to a user equipment (UE). The modulation and coding scheme index may be applied to encoding or decoding a transport block. The modulation and coding scheme may be associated with at least two modulation orders or a differential indication according to a modulation and coding scheme table. To determine which of the modulation orders for processing the transport block, the UE and the base station may use a prior modulation order associated with a prior transmission of the transport block. The UE may process the transport block by encoding or decoding the transport block based at least in part on the determined modulation order.

Abstract: Techniques for processing of symbols (e.g., orthogonal frequency division multiplexing (OFDM) or single carrier-frequency division multiple access (SC-FDMA) symbols) provide enhanced out-of-band (OOB) suppression of the symbols and also provide reduced inter-symbol interference (ISI) between a symbol and a subsequent symbol. Multiple frequency tones of a symbol may be divided into two or more subsets of tones. For example, subsets of tones associated with a head portion or a tail portion of an OFDM symbol may be processed with a relatively long weighted overlap-add (WOLA) weighting length or filtering length, and a subset of tones associated with a center portion of the OFDM symbol may be processed with a relatively short WOLA weighting length or filtering length. Such heterogeneous processing of tones within a symbol may provide enhanced inter-channel interference (ICI) and improved OOB suppression and also provide reduced ISI for the center tones of the symbol.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive an indication of a set of channel state information reference signal (CSI-RS) port mappings for different antenna adaptation levels of a base station. The UE may receive, from the base station, a CSI-RS in accordance with a first CSI-RS port mapping, from the set of CSI-RS port mappings, for a first antenna adaptation level of the different antenna adaptation levels. Numerous other aspects are described.

Abstract: A communications transceiver system that employs self-interference mitigation techniques can detect static objects by using techniques that introduce angular or Doppler diversity. This can include moving Tx and Rx antennas and/or performing beam sweeping. When processing RF sensing data from reflected RF signals, self-interference mitigation techniques can be used and compensation can be made for the movement and/or beam sweeping to allow for both self-interference mitigation and detection of static objects.

Abstract: Methods, systems, and devices for line of sight (LOS) multiple input multiple output (MIMO) signaling aspects are described. In some examples, a wireless device may transmit, to a network device, a capability message indicating that the wireless device supports a LOS mode. In such examples, the wireless device may receive, from the network device in response to the capability message, a control message indicating activation of the LOS mode and at least one LOS mode parameter based at least in part on a channel measurement associated with a wireless channel between the wireless device and the network device indicating that the wireless channel satisfies a LOS path criterion. In some examples, the wireless device may communicate a message with the network device in accordance with the LOS mode parameter.

Abstract: In an aspect, the present disclosure includes a method, apparatus, and computer readable medium for wireless communications for transmitting, by a UE to a network entity, a radio resource control (RRC) configuration message indicating a full-duplex capability of the UE; receiving, by the UE from the network entity, a downlink control information (DCI) message, wherein the DCI message enables concurrent transmission on an uplink channel and reception on a downlink channel by the UE; and communicating, between the UE and the network entity, based on the DCI message.

Abstract: Methods, systems, and devices for wireless communications are described. Some wireless communications systems may support cross link interference (CLI) mitigation in full-duplex operations. For example, a first user equipment (UE) may encode and precode a first portion of a message according to a first modulation and coding scheme (MCS) and a first precoding matrix and a second portion of the message according to a second MCS and a second precoding matrix. The first precoding matrix may be based on a first communication link between the first UE and a network entity and the second precoding matrix may be based on the first communication link and a second communication link between the first UE and a second UE. The first UE may transmit the first portion of the message and the second portion of the message via beams associated with respective precoding matrices.
