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: 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.

Abstract: A method for wireless communication at a user equipment (UE) and related apparatus are provided. In the method, the UE receives, from a first reader device, multiple continuous wave (CW) signal sets. Each CW signal set of the multiple CW signal sets includes at least one CW signal. The UE further generates a set of reference signals corresponding to CW signals in the multiple CW signal sets, where the set of reference signals is generated based on at least one of a frequency spread or a frequency shift on the CW signals in the multiple CW signal sets. The UE further transmits, to the first reader device or a second reader device different from the first reader device, the set of reference signals corresponding to the multiple CW signal sets. The method allows for improved channel estimation while adhering to the power spectrum density (PSD) limitations.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a first scheduling message from a first transmit receive point (TRP) and a second scheduling message from a second TRP. The UE may detect a scheduling collision based at least in part on a first scheduled communication of the first scheduling message and a second scheduled communication of the second scheduling message overlapping in time. The UE may selectively transmit one or more of the first scheduled communication or the second scheduled communication based at least in part on the detecting the scheduling collision. Numerous other aspects are described.

Abstract: Mechanisms for transmitting a plurality of uplink (UL) transmission block (TB) repetitions associated with a plurality of TBs in a configured grant (CG) resource are provided. In one aspect, a method for multi-TB PUSCH repetition performed by a CE includes determining, based on a first parameter and a second parameter, a number of transport blocks (TBS) for a multi-TB repetition uplink (UL) communication in a configured grant (CG) resource, where the first parameter indicates a first number of TB repetitions, and where the second parameter indicates a second number of TB repetitions. The method further includes transmitting, to a base station (BS) using the CG resource in an unlicensed band, a plurality of TB repetitions based on the determined number of TBs.
