Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive one or more downlink messages and generate one or two bits of hybrid automatic repeat request-acknowledgment (HARQ-ACK) information. The UE may generate an uplink control information (UCI) message by either transmitting a single HARQ bit (to which a receiving network entity adds an implicit zero-padding bit), or by appending one or more explicit zero-padding bits to the HARQ information to generate a zero-padded HARQ bit sequence. In some aspects, the payload size of the zero-padded HARQ bit sequence may include two or three bits. The UE may then transmit the UCI message in accordance with a sequence cyclic shift value (or other encoding scheme) corresponding to the payload size of the zero-padded HARQ bit sequence. The receiving network entity may then receive and interpret the implicitly zero-padded HARQ information or the explicitly zero-padded HARQ information.

Abstract: Some wireless communications systems may utilize optical wireless communication (OWC) to transmit or receive information. For instance, a first device may communicate with a second device via an OWC link. Some OWC systems may operate in an optical spectrum between approximately 1011 and 1016 hertz. Some examples of the techniques described herein may provide communication performance improvements by utilizing frequency-dependent communication structures for OWC. For example, frequency-dependent constellation patterns may be utilized for a codeword. Utilizing frequency-dependent constellation patterns may contrast with some approaches that utilize one modulation and coding scheme (MCS) per codeword. In some aspects, allocated frequency domain resources may be arranged into subbands with different MCSs. In some examples, an optical channel with relatively little or no fading may allow streamlining of channel state or control signaling. For example, MCS patterns may be updated relatively less frequently.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a control message indicating to switch from a first slot format to a second slot format. The first slot format may include symbols for reference signal transmissions and symbols for data transmissions.

Based on a capability of the UE and the control message, the UE may switch to the second slot format and communicate a reference signal in a symbol configured for FDM. That is, the reference signal may be FDMed with data according to the second slot format.
