Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a control message indicating a coding rate value corresponding to a downlink control information (DCI) format. The coding rate value may indicate a coding rate of the DCI format. The UE may receive, via a quantity of resource elements (REs) that is based on a payload size and the coding rate value, a DCI message of the DCI format that includes scheduling information associated with a data message, and the UE may receive the data message in accordance with the scheduling information. In some examples, the UE may receive the DCI message via a physical downlink control channel (PDCCH) multiplexed with a physical downlink shared channel (PDSCH) that carries the data message.

Abstract: This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for multi-bit feedback via a sidelink feedback channel. In some aspects, a first user equipment (UE) and a second UE may support a physical sidelink feedback channel (PSFCH) design that is capable of conveying multi-bit feedback across multiple resource blocks. For example, the first UE may monitor for one or more sidelink data messages from the second UE and may transmit, to the second UE over multiple resource blocks of a PSFCH, a feedback message indicating multiple feedback bits associated with the sidelink data messages. The first UE may indicate or otherwise convey the multiple feedback bits via various sequence types or coding schemes. Additionally, or alternatively, the first UE and the second UE may support a resource selection scheme involving one or more parameters associated with conveying multi-bit feedback over a PSFCH.

Abstract: Methods, systems, and devices for wireless communications are described. A first wireless device may monitor a set of physical sidelink shared channel (PSSCH) resources for sidelink messages from a second wireless device. The first wireless device may generate one or more codebooks that include acknowledgement (ACK) or negative acknowledgement (NACK) bits corresponding to the sidelink messages. The first wireless device may transmit one or more feedback messages to the second wireless device on one or more physical sidelink feedback channel (PSFCH) resources in accordance with a sidelink feedback configuration of the first wireless device. The one or more feedback messages may include an indication of the one or more codebooks. The techniques described herein may enable the first wireless device to transmit the one or more feedback messages to the second wireless device with higher throughput and greater signaling efficiency, among other benefits.

Abstract: Methods, systems, and devices for wireless communications are described. In some wireless communications systems, a user equipment (UE) may receive an indication of a configuration for transmitting a propagation delay compensation (PDC) report and a reference signal resource for performing one or more round trip timing (RTT) measurements associated with the PDC report. The UE may receive control signaling from the base station which includes a request for the UE to transmit the PDC report which includes the one or more RTT measurements. The UE may transmit the PDC report based on receiving the request from the base station, and the UE may perform one or more PDC procedures based on transmitting the PDC report. In some other examples, the base station may transmit a request to a higher layer to obtain the RTT measurements, and may relay the RTT measurements to the UE for performing the PDC procedures.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) in an optical wireless communications system may utilize a curved focal plane of a condenser lens to communicate an optical wireless signal. An optical front-end (OFE) of the UE may include one or more optical communication components located at varying distances from the condenser lens on a curved focal plane of the condenser lens. Additionally or alternatively, the UE may adjust a position of one or more optical communication components on the curved focal plane. Additionally or alternatively, the OFE may include an array of condenser lenses and optical communication components each optically coupled with one or more condenser lenses. The UE may perform equal gain combination and/or equal ratio power splitting to communicate an optical wireless signal using the array of condenser lenses and optical communication components.

Abstract: Disclosed are techniques for wireless communication. In an aspect, a radio frequency identification (RFID) station may receive a first packet from an RFID tag at a first arrival time. The RFID station may receive a second packet from the RFID tag at a second arrival time after the first arrival time. The RFID station may estimate a distance between the RFID station and the RFID tag based on an inter-packet arrival time between the first packet and the second packet, the inter-packet arrival time being based on a time difference between the first arrival time and the second arrival time.

Abstract: Wireless communications systems and methods related to communicating in a communication medium are provided. A base station (BS) receives from a user equipment (UE), feedback information of the UE. The BS determines a schedule for the UE. The schedule includes a scheduling duty cycle based on the feedback information of the UE. The BS communicates with the UE, a communication signal based on the schedule.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first user equipment (UE) may transmit, to a second UE, a first channel occupancy time (COT) sharing request. The UE may transmit, to a third UE, after a time window has elapsed, a second COT sharing request, wherein the second COT sharing request is transmitted based at least in part on the first UE having received no response to the first COT sharing request within the time window or the first UE having received a negative response to the first COT sharing request within the time window. Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive control signaling identifying a scheduling configuration indicating a first search space set and a second search space set of a scheduling component carrier for scheduling communications on a scheduled component carrier, and may identify a search space set linking configuration for a group of search space sets of the scheduled component carrier based on the scheduling configuration. The UE may identify a set of decoding candidates within the first and second search space sets which are allocated for cross-carrier scheduling of the scheduled component carrier based on the search space set linking configuration. The UE may then receive at least one control message schedules a communication between the base station and the UE over the scheduled component carrier within at least one decoding candidate, and may perform the scheduled communication over the scheduled component carrier.

Abstract: Aspects of the present disclosure relate to wireless communications, and more particularly, to techniques for channel access for wireless communications. One aspect provides a method for wireless communications at a user equipment (UE). The method generally includes obtaining a channel occupancy time (COT) structure information (COT-SI) message and obtaining at least one downlink control information (DCI) indicating multiple beams and listen before talk (LBT) scheme indications associated with the multiple beams. The method generally includes determining an LBT scheme to be used for transmission via each of the multiple beams based on the LBT scheme indications and the COT-SI message, and outputting signaling for transmission on each of the multiple beams based on the LBT scheme.
