  • Publication number: 20250150250
    Abstract: Methods, systems, and devices for wireless communications are described. A network entity (e.g., a user equipment) may receive information that configures physical downlink control channel (PDCCH) monitoring in a search space set. The network entity may receive control information that indicates an uplink transmission, wherein a collision condition exists between the PDCCH monitoring in the search space set and the uplink transmission. The network entity may perform, during operation in a half-duplex mode, an action in accordance with a collision handling rule, wherein the collision handling rule is based on the collision condition and the search space set.

  • Publication number: 20250133536
    Abstract: Methods, systems, and devices for wireless communications are described. A non-terrestrial network (NTN) cell may transmit a pre-paging message for which a user equipment (UE) may monitor based on a synchronization signal block (SSB) and a pre-paging configuration. For example, the UE may be configured with a pre-paging configuration for one or more NTN cells that may be used to identify an SS and a CORESET in which to monitor for a pre-paging message. The UE may identify the pre-paging configuration for a specific NTN cell based on a cell identifier for the NTN cell identified based on decoding an SSB from the NTN cell. The UE may identify the CORESET and the SS based on the pre-paging configuration and the resource via which the SSB was received. Thus a UE may receive a pre-paging message from an NTN based on receiving and decoding an SSB in low SINR scenarios.

  • Patent number: 12273858
    Abstract: Idle discontinuous reception (I-DRX) cycles at a user equipment (UE) may be extended via leveraging of paging assistance from a second UE. For example, a low complexity UE may have a connection to a network (e.g., via a link to a base station) as well as a connection to another UE (e.g., via a device-to-device link to a regular UE). In cases where such a low complexity UE receives paging messages from the network, a UE associated with a device-to-device link of the low complexity UE may monitor paging messages on behalf of the low complexity UE. As such, the low complexity UE may extend its I-DRX cycle, as the assisting UE monitors paging information for the low complexity UE. The assisting UE may forward paging information for the low complexity UE according to paging occasions of the extended I-DRX cycle of the low complexity UE.

  • Publication number: 20250113399
    Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE), such as an unmanned aerial vehicle (UAV) (e.g., a source UAV), may initiate a unicast link establishment procedure with another UAV (e.g., a target UAV), which may enable the UAVs to communicate according to an air-to-everything (A2X) service type. The source UAV may transmit a direct communication request (DCR) message to the target UAV that includes an application-layer identifier (ID) that is unique to the target UAV. The source UAV may derive the application-layer ID for the target UAV from a UE-specific ID that is unique to the target UAV. Alternatively, the source UAV may transmit a DCR message that excludes target UAV information. Instead, the DCR message may indicate one or more proximity parameters associated with the source UAV. The UAVs may communicate unicast messages via the unicast link according to A2X configurations and communication parameters.

  • Patent number: 12250695
    Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a downlink control information (DCI) message from a base station that schedules multiple transport blocks (TBs) to be transmitted to the UE. Accordingly, the UE may determine a bundling configuration for grouping the multiple TBs into separate groups of TBs such that separate acknowledgment (ACK) feedback messages are transmitted by the UE for each group of TBs to indicate whether each of the TBs in each TB group was correctly received and decoded. In some cases, the UE may determine the bundling configuration based on radio resource control signaling from the base station, DCI signaling from the base station, relationships or equations or tables defined for the UE, or a combination thereof. Additionally, the UE may determine resource locations and timelines for transmitting the separate ACK feedback messages.

  • Patent number: 12244421
    Abstract: The disclosure relates to methods, devices, and systems for wireless communications. In some wireless communications systems, a base station may transmit a multicast message to a group of user equipment (UEs), and the UEs may provide feedback for the multicast message. In some implementations, the base station may configure the UEs to transmit feedback for multicast messages. In some example, the UEs may transmit group-negative acknowledgment (NACK) feedback information for multicast messages that are not successfully received at the UEs. In some other examples, each UE may be configured with UE-specific uplink control channel resources for transmitting hybrid automatic repeat request (HARQ) feedback for a multicast message. In some implementations, a UE may support feedback for both unicast and multicast messages. The semi-static codebook for unicast, multicast, or both may account for whether the UE is capable of concurrently receiving unicast and multicast messages in a slot.
