Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may be configured to receive, from a network node, control signaling indicating a first downlink bandwidth part (BWP) and a first uplink BWP, or a first downlink sub-band and a first uplink sub-band, or both, for performing sub-band full-duplex (SBFD) communications. The UE may receive, from the network node, a downlink control information (DCI) message indicating to switch to a second downlink BWP and a second uplink BWP, or to switch to a second downlink sub-band and a second uplink sub-band, or both. The UE may then perform full-duplex communications with the network node within the second downlink BWP and the second uplink BWP, or within the second downlink sub-band and the second uplink sub-band, or both.

Abstract: Methods, systems, and devices for wireless communications are described. A network node may transmit, to a plurality of user equipment (UE), a set of network encoded packets generated using a set of packets. A UE of the plurality of UEs may receive a subset of the set of encoded packets and may decode the subset to determine a first set of decoded packets. The UE may receive a second set of decoded packets from the plurality of UEs. The UE may transmit feedback to the network node that indicates the successfully decoded packets of the first and second sets. The network node may receive the feedback and may determine a subset of the set of packets that was successfully decoded for each UE providing the feedback. The network node may transmit an updated set of network encoded packets to the plurality of UEs.

Abstract: Aspects relate to mechanisms for wireless communication devices to update transmission configuration indicator states (TCI-states), spatial relation (SR) indicators (SRIs), or pathloss reference signals (PL-RSs) for a group of two or more component carriers (CCs) for multi-component carrier communication. A radio access network (RAN) node may generate a message indicating one or more TCI-states, one or more SRs, or one or more PL-RSs to utilize for multi-CC communication. The message may include an index identifying a group of two or more CCs of a plurality of access CCs or a plurality of sidelink CCs associated with the one or more TCI-states, the one or more SRs, or the one or more PL-RSs. A user equipment (UE) may receive the message and update the one or more TCI-states, the one or more SRs, or the one or more PL-RSs for the group of two or more CC for the multi-CC communication based on the message.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a first signal associated with a downlink control channel, wherein the first signal uses a modulation signature that identifies a first security key associated with a reconfigurable intelligent surface (RIS), and wherein the first signal includes a second security key. The UE may receive a second signal associated with a downlink shared channel, wherein the second signal includes a third security key, and wherein the second signal is authenticated by the UE based at least in part on the first security key, the second security key, and the third security key. Numerous other aspects are described.

Abstract: One or more anchor nodes, which may be sidelink devices, may transmit positioning reference signals (PRSs) to a wireless device, such as a user equipment (UE). The UE may select one or more PRSs to process based on respective priorities of the PRSs. At least one anchor node may transmit a priority indication including the respective priorities, or the one or more anchor nodes may transmit the PRSs according to a scrambling sequence or pattern to implicitly indicate the respective priorities. The UE may decode one or more PRSs based on the respective priorities.

Abstract: Techniques and devices for wireless communications are described. A user equipment (UE) may receive a first message from a network entity that indicates a configuration for reporting spatial domain basis function updates to the network entity. The UE may transmit a full channel state information (CSI) report and a partial CSI report to the network entity based on the indicated configuration. The full CSI report may indicate a set of spatial domain basis functions and the partial CSI report may indicate an update for the set of spatial domain basis functions. The update for the set of spatial domain basis functions may be relative to the full CSI report or a previously transmitted partial CSI report. In some examples, the UE may receive a second message from the network entity based on the partial CSI report.

Abstract: Certain aspects of the present disclosure provide techniques for quasi-colocation (QCL) assumption for an aperiodic channel state information (A-CSI) reference signal (RS) configured with multiple transmission reception point (mTRP). A user equipment (UE) may receive signaling configuring the UE with a plurality of index values associated with different control resource sets (CORESETS). The UE may receive, from a base station (BS), first downlink control information (DCI) triggering an A-CSI-RS resource set for A-CSI reporting. The first DCI is received in a first CORESET of the different CORESETs associated with a first index value of the plurality of index values. The UE may determine a first time offset between the first DCI and the A-CSI-RS resource set. When the first time offset is smaller than a threshold time offset, the UE may determine a QCL assumption for receiving the A-CSI-RS based, at least in part, on the first index value.

Abstract: Aspects of the present disclosure relate to wireless communications, and more particularly, to techniques for signaling user equipment (UE) capability for sharing quasi co-location (QCL) parameter across a group of frequency bands. For example, the UE may report, to a network entity, a capability of the UE to apply a common spatial QCL parameter for at least one group of frequency bands. The UE receives an indication of a change to the common transmission control indicator (TCI) states or spatial relation parameter to be applied across the group of frequency bands. The UE applies the change across the group of frequency bands.

Abstract: Methods, systems, and devices for wireless communications are described that provide for timing adjustments that may be used in communications between wireless devices in a wireless communications system and signaling of such timing adjustments using physical layer signaling (e.g., layer 1 (L1) signaling). A first timing adjustment may be provided by a parent node to one or more associated child nodes that corresponds to a propagation delay between the parent node and its control node or a relay node through which the parent node communicates with a core network. In some cases, the physical layer signaling used to transmit the first timing adjustment may be a reference signal transmission, a downlink control information transmission, or any combination thereof.

Abstract: A method, a computer-readable medium, and an apparatus are provided. The apparatus may be an IAB node. The apparatus may receive communication from one or more of a parent IAB node or a child IAB node using a first frequency carrier of a paired spectrum comprising the first frequency carrier and a second frequency carrier. The apparatus may transmit communication to the one or more of the parent IAB node or the child IAB node using the second frequency carrier in the paired spectrum. At least one of the first frequency carrier or the second frequency carrier in the paired spectrum carries both uplink and downlink communication.
