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: Code block group (CBG) transmission indications for communications configured with multiple transmission time interval (TTI) grants is disclosed. Where multiple TTIs are configured for CBG transmission, the base station may select to signal CBG transmission indications and/or transport block (TB)-level new data indicator (NDI) for each of the configured TTIs along with an index of the TTIs that CBG transmission indicators are sent for. The base station may select to add one or more CBG transmission indications based on the predetermined payload size of the transmission indication signal of the physical downlink control channel (PDCCH).

Abstract: This disclosure provides methods for transmissions and retransmissions over a configured grant (CG) physical uplink shared channel (PUSCH) and for transmissions over physical uplink control channel (PUCCH) resources in multi-transmission and reception point (TRP) deployments. A user equipment (UE) may receive signaling configuring a first set of power control parameters and a second set of power control parameters for a CG-PUSCH resource. Additionally or alternatively, the UE may receive signaling activating a first closed-loop power control operation and a second closed-loop power control operation for a PUCCH resource. In some scenarios, the UE may receive a fallback downlink control information (DCI) format activating or scheduling the CG-PUSCH resource or indicating the PUCCH resource. In such scenarios, the UE may employ one or both of a power control selection rule or a transmit power control (TPC) command application rule for a transmission over the CG-PUSCH resource or the PUCCH resource.

Abstract: Disclosed are techniques for environment sensing. In an aspect, a transmitter base station determines a configuration for a radio frequency (RF) sensing signal, the configuration determined based at least in part on coordination among a plurality of base stations, and transmits the RF sensing signal to at least one receiver base station based on the configuration. In an aspect, a receiver base station receives a configuration for an RF sensing signal, the configuration determined based at least in part on coordination among a plurality of base stations, receives, from at least one transmitter base station, the RF sensing signal, and detects at least one target object based, at least in part, on reception of the RF sensing signal.

Abstract: Aspects relate to techniques for enhancing sidelink scheduling information to include a priority assigned to a sidelink transmission. For example, a transmitting wireless communication device may receive sidelink scheduling information scheduling a sidelink transmission from a transmitting wireless communication device to a receiving wireless communication device. The sidelink scheduling information may further include a priority indicator associated with the sidelink transmission. The transmitting wireless communication device may then transmit the sidelink transmission to the receiving wireless communication device based on the scheduling information. The priority indicator may further facilitate hybrid automatic repeat request (HARQ) codebook construction on the sidelink and uplink for the transmission of acknowledgement information of the sidelink transmission.

Abstract: This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for maintaining, between a user equipment (UE) and a component of a base station (BS), a mutual understanding of a set of linked physical downlink control channel (PDCCH) candidates if the UE selects to monitor a subset of the linked PDCCH candidates. In one aspect, the UE may monitor the subset of the linked PDCCH candidates, and the UE and the component of the BS may select a reference PDCCH candidate from which to define scheduling information in accordance with the UE monitoring the subset of the linked PDCCH candidates. In some examples, the UE and the component of the BS may select the reference PDCCH candidate in accordance with one or more mutually understood rules or procedures such that the UE and the component of the BS may select a same reference PDCCH candidate.

Abstract: This disclosure provides systems, methods, and devices for wireless communication that support backscatter based positioning. In a first aspect, a method of wireless communication includes receiving, from a transmit network entity, a data signal via a first channel. The method also includes receiving, from a tag device, a backscatter signal based on the data signal received by the tag device via the first channel. The backscatter signal is received via a second channel that is different from the first channel. The method further includes transmitting a report that indicates a position measurement associated with a position of the tag device. The position measurement is determined based on the received data signal and the received backscatter signal. Other aspects and features are also claimed and described.

Abstract: A proxy sensing-based channel access procedure is discussed for shared spectrum networks. Within a given network, a distribution of proxy nodes may be deployed around a network operating area. A control node, which controls the proxy sensing mode for the network, may configure the active network nodes to conduct communications via the shared communication spectrum without first performing any type of channel sensing on the shared communication spectrum. The control node may then also configured the proxy nodes to perform channel sensing on the shared spectrum for the entire network. Using the reported channel sense results from the proxy nodes, the control node may determine whether detected interference is occasional or persistent, and whether to take some action to modify the communications or operations of the network.

Abstract: This disclosure provides systems, methods, and apparatus, including computer programs encoded on computer-readable media, for implementing signaling for indicating a scheduled full duplex (FD) uplink (UL) and downlink (DL) traffic scheduling combination for differentiation of FD traffic. In some aspects, a BS may transmit a downlink control information (DCI) message that includes an indication of the scheduled FD UL and DL traffic scheduling combination. The FD UL and DL traffic scheduling combination may identify scheduled UL and DL transmissions for FD mode operation. The UE may receive the DCI message and identify the scheduled FD UL and DL traffic scheduling combination. In some aspects, the BS may provide a DCI message to the UE that indicates whether a DL transmission is being scheduled that at least partially overlaps with a scheduled UL transmission. The UE may initiate a power save mode based on the received DCI message.
