Abstract: Various aspects of the disclosure relate to beam information for independent links. For example, beam information for one link may be sent on at least one other link. In some aspects, the independent links may involve a first device (e.g., a user equipment) communicating via different independent links with different devices (e.g., transmit receive points (TRPs) or sets of TRPs). For example, the first device may communicate with a second device (e.g., a TRP) via a first link and communicate with a third device (e.g., a TRP) via a second link. In some scenarios, one link can indicate beam switching for at least one other link. In some scenarios, one link can indicate link recovery for at least one other link. In some scenarios, one link can indicate link failure for at least one other link.

Abstract: Wireless communications systems and methods related to stand-alone sidelink communication are provided. A first user equipment (UE) determines system parameter information to initiate a sidelink communication. The first UE transmits, in one or more first subbands of a plurality of subbands within a shared radio frequency during a first time period, the system parameter information. The first UE communicates, with a second UE in a second subband of the plurality of subbands during a second time period different from the first time period, sidelink data based on the system parameter information.

Abstract: Wireless communications systems and methods related frame based equipment (FBE) communications in a wireless communication network are provided. For example, a method of wireless communication performed by a user equipment can include: monitoring, in a search space of a shared radio frequency band, for a downlink communication from a base station operating in a frame based equipment (FBE) mode; receiving, from the base station based on the monitoring, downlink control information (DCI); determining, based on the received DCI, the DCI does not schedule a physical downlink shared channel (PDSCH) communication for the user equipment; and transmitting, to the base station based on the determining, an uplink communication.

Abstract: Wireless communications systems and methods related to communicating control information are provided. A method of wireless communication performed by a first user equipment (UE) may include transmitting, to a second UE in a first time period, a resource reservation indicating resources associated with at least one channel state information reference signal (CSI-RS), transmitting, to the second UE, the at least one CSI-RS in a second time period, wherein the second time period is at least K time periods after the first time period, and receiving, from the second UE, a CSI report based on the at least one CSI-RS.

Abstract: Disclosed are techniques for wireless communication. In an aspect, a UE determines a sidelink resource configuration for a slot, wherein the sidelink resource configuration includes a first set of resources carrying a first PSSCH in a first mini-slot of the slot, a second set of resources carrying a second PSSCH in a second mini-slot of the slot, and a third set of resources carrying a PSFCH associated with one or more PSSCHs of one or more preceding slots. The UE may communicate data over at least a portion of the slot in accordance with the sidelink resource configuration. In some designs, a sidelink management device (e.g., the UE, another UE, or a network component) may transmit the sidelink resource configuration.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive an uplink grant that schedules a sounding reference signal (SRS) transmission and a physical uplink shared channel (PUSCH) transmission and indicates one or more parameters for determining a cyclic prefix extension. The UE may determine the cyclic prefix extension based at least in part on the one or more parameters. The UE may transmit the SRS transmission with the cyclic prefix extension after performing a listen before talk (LBT) procedure. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described. A wireless device such as a UE or a base station may implement one or more listen before talk (LBT) techniques. The wireless device may determine to transmit a communication during a transmission time interval on multiple subbands of a radio frequency spectrum band. The wireless device may identify whether the transmission time interval is during a channel occupancy time for the base station for a first set of subbands of the multiple subbands. The wireless device may perform one or more LBT procedures based on the identification. For example, the wireless device may perform an LBT procedure that is selected for each subband based on identifying that the transmission time interval is during the channel occupancy time for the first set of the subbands. The wireless device may transmit the communication based on a result of the LBT procedures.

Abstract: Aspects relate to techniques for configuring intermittent time domain resources that are usable by a user equipment (UE) for communication with a base station. The base station may transmit a usable time domain resource (TDR) configuration to the UE that indicates the usable time resources that are available to the UE for communication with the base station. The UE may then communicate with the base station based on the usable TDR configuration.

Abstract: Apparatus, methods, and computer-readable media for facilitating phase jump estimation for SL DMRS bundling are disclosed herein. An example method includes receiving, from another device, first information at a first symbol of a first slot, the first slot including at least the first symbol and a first reference signal. The example method also includes receiving second information at a second symbol of a second slot, the second slot including at least the second symbol and a second reference signal, the first information and the second information being repetitions. The example method also includes generating a first reference signal copy based at least on the second reference signal and a phase jump between the first slot and the second slot. Additionally, the example method includes performing channel estimation across the first slot and the second slot based on an aggregation of the first reference signal and the first reference signal copy.
