Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may obtain updated location information, and determine a time difference between a previous communication with a network and a scheduled uplink transmission. Based on the determined time difference, the UE may determine a timing advance (TA) component of a TA value to apply for the uplink transmission, and transmit an uplink message in the uplink transmission according to the determined TA value and the location information. In some examples, the time difference may be based on a first duration between the uplink transmission and a previous uplink transmission, a second duration between the uplink transmission and a previous TA command received from the network, or both. In some examples, the determined TA value may be based on additional parameters, such as an autonomous adjustment step, an aggregate adjustment rate, a scaling factor, or any combination thereof.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may receive a configuration for monitoring one or more physical downlink control channels (PDCCHs) for downlink control information (DCI) that schedules physical downlink shared channel (PDSCH) communications on each carrier included in a set of carriers and for DCI that schedules physical uplink shared channel (PUSCH) communications on one or more carriers. The UE may monitor the one or more PDCCHs for DCI in accordance with the configuration. The UE may receive DCI that schedules a PUSCH communication on the one or more carriers based at least in part on the monitoring. Numerous other aspects are provided.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a base station may configure an uplink transmission pattern related to an uplink transmission resource on multiple component carriers. The base station may transmit, to a user equipment (UE), information related to activating the uplink transmission pattern in a single scheduling message. Accordingly, the UE may transmit information on the multiple component carriers in one or more uplink symbols based at least in part on the uplink transmission pattern. Numerous other aspects are provided.

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: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive configurations of a set of tracking reference signal (TRS) resource sets. The UE may receive an availability indication associated with one or more TRS resource sets from the set of TRS resource sets, and the availability indication is associated with one or more groups of TRS resource sets associated with the set of TRS resource sets. 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.
