Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a New Radio (NR) user equipment (UE) may receive a configuration that configures the NR UE with a capability to use a Long Term Evolution (LTE) cell-specific reference signal (CRS) for updating a tracking loop. The NR UE may receive an LTE CRS. The NR UE may update the tracking loop based at least in part on the LTE CRS. Numerous other aspects are described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a non-terrestrial network (NTN) entity, a message that is associated with an uplink grant. The UE may select, based at least in part on the message, either a cell-specific offset or an updated offset that is indicated after initial access, as a timing offset that accounts for a propagation delay between a base station of the NTN and the UE. The UE may transmit, to the NTN entity, an uplink communication using the timing offset. Numerous other aspects are described.

Abstract: Certain aspects of the present disclosure provide techniques for providing feedback. For example, a user equipment (UE) may receive, from a network node, a configuration of a search space comprising time and frequency resources available to the network node for communicating a downlink control channel, the configuration indicating a feedback process type corresponding to the search space. The UE may also receive, from the network node, the downlink control channel in the search space. The UE may also receive a downlink transmission scheduled by the downlink control channel. The UE may selectively provide feedback to the network node regarding decoding of the downlink transmission according to the feedback process type corresponding to the search space.

Abstract: Methods, systems, and devices for wireless communications are described in which a base station may configure a user equipment (UE) with a low latency mode indication that indicates one or more different retransmission timelines or repetition techniques relative to communications that are not associated with the low latency mode indication. The base station may provide the low latency mode indication in downlink control information (DCI) that may include a resource grant for uplink resources for an uplink communication, such as for a UE transmission of pose information of an extended reality (XR) application. The low latency mode indication may signal that no retransmissions of the uplink communication are to be transmitted, that a different retransmission timeline is enabled for low latency mode communications, that retransmissions may happen based on a particular timeline that is determined according to one or more timers, or any combinations thereof.

Abstract: Generally, the described techniques provide for duplex mode configuration for control information (e.g., duplex mode configuration for communication of downlink control information). For example, duplex modes may be defined (e.g., as full duplex (FD) capable, FD only, half duplex (HD) only, etc.), and such duplex modes may be configured for control resource sets (CORESETs), search space (SS) sets, or both. In some examples, duplex modes configured for a CORESET/SS set may depend on the priority of information conveyed via the CORESET/SS set. For example, a CORESET/SS set for high priority or critical control information may be configured with a HD mode to avoid FD self-interference, while CORESET/SS set for other control information may be configured with a FD mode to improve spectrum efficiency. Techniques for resolving conflicting duplex mode configurations (e.g., when a HD mode is configured for a SS set within a CORESET configured with FD) are also described.

Abstract: This disclosure provides systems, methods, and devices for wireless communication that support dynamic network-side cell discontinuous reception (DRX) control and scheduling. In a first aspect, a method of wireless communication includes transmitting an end of transmit (TX) traffic indicator. The method also includes receiving an early termination indicator associated with a scheduled network-side cell discontinuous reception (DRX) active time. The method further includes refraining from transmitting data traffic during at least a remainder of the scheduled network-side cell DRX active time. Other aspects and features are also claimed and described.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive, from a network entity, one or more control messages that indicate a configuration for a first downlink bandwidth part (BWP) associated with a first operating mode of the UE, a second downlink BWP associated with a second operating mode of the UE, a first set of resources within the first downlink BWP, and a second set of resources within the second downlink BWP. At least a portion of the configuration may correspond to a capability of the UE. The UE may monitor the first set of resources while in the first operating mode, and may monitor the second set of resources while in the second operating mode. The UE may receive a system information update or a public warning system (PWS) notification from the network entity via the second set of resources.

Abstract: This disclosure provides systems, devices, apparatus, and methods, including computer programs encoded on storage media, for PDSCH rate-matching in NTN systems. A UE may receive an indication of a subset of one or more SSB beams included in a set of SSB beams having one or more PDCCH resources reserved for potentially scheduling one or more SIBs associated with the set of SSB beams. The UE may further receive a PDSCH associated with resources that overlap with at least a portion of the one or more PDCCH resources associated with the indication of the subset of one or more SSB beams, and rate-match around the one or more PDCCH resources associated with the indication of the subset of one or more SSB beams for receiving the PDSCH.

Abstract: Methods, systems, and devices for wireless communications are described. For instance, a user equipment (UE) may receive a configuration of a set of search space sets for a downlink control channel. The UE may determine a quantity of downlink control channel units (e.g., downlink control channel elements, downlink control channel candidates) for monitoring over the set of search space sets, where downlink control channel units that overlap may be counted separately. For instance, the downlink control channel units may overlap in time and frequency and/or may have a same associated payload size and associated set of control channel elements. The UE may monitor the downlink control channel according to a subset of the set of search space sets, where the subset excludes one or more of the set of search space sets based on the quantity of downlink control channel units satisfying a threshold.
