Abstract: An effective approach for a user equipment (UE) to perform a sidelink communication with another UE in a discontinuous reception (DRX) mode is disclosed. For example, a UE may determine a direct frame number (DFN) timing, and configure a sidelink DRX mode using one or more sidelink DRX parameters based on the DFN timing. The UE may perform a sidelink communication with a second UE during an on-duration of a sidelink DRX cycle in the sidelink DRX mode according to the one or more sidelink DRX parameters.

Abstract: A first user equipment (UE) transmits, to a second UE, a transmission configuration indicating first timing information for a discontinuous reception (DRX) configuration for sidelink transmission from the first UE. The first UE transmits, to the second UE, a reception configuration indicating second timing information for the DRX configuration for sidelink reception by the first UE. The first UE receives a response from the second UE confirming or rejecting the DRX configuration.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a transmitting (Tx) user equipment (UE) may perform, to a receiving (Rx) UE, a first sidelink transmission in an on duration of a sidelink discontinuous reception (DRX) cycle associated with a sidelink DRX configuration. The Tx may activate a sidelink DRX timer based at least in part on the sidelink DRX configuration, wherein the sidelink DRX configuration is associated with a destination identifier (ID) and one or more source IDs are associated with the destination ID, and wherein the sidelink DRX timer is operated per a pair of source ID and destination ID. Numerous other aspects are described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a transmit user equipment (UE) may determine that a channel busy ratio satisfies a channel busy ratio threshold. The transmit UE may reserve, based at least in part on determining that the channel busy ratio satisfies the channel busy ratio threshold, a resource for transmission of a packet with a particular priority to the receive UE, wherein the resource is in a set of resources outside of a sidelink discontinuous reception (DRX) on duration of a receive UE. The transmit UE may transmit the packet using the resource based at least in part on reserving the resource.

Abstract: Certain aspects provide a method for wireless communication by a user equipment (UE). The method generally includes determining one or more sidelink discontinuous reception (DRX) configurations associated with at least a communication on a sidelink, determining a wake up indication configuration associated with the one or more sidelink DRX configurations, monitoring for at least one wake up indication from at least one other UE based on the wake up indication configuration, the at least one wake up indication indicating a sidelink DRX on phase associated with the sidelink DRX configuration, deciding an action for the sidelink DRX on phase based on the at least one wake up indication for the at least one communication on the sidelink, and performing the action in accordance with the decision.

Abstract: Certain aspects provide a method for wireless communication by a user-equipment (UE). The method generally includes receiving one or more configurations for sidelink discontinuous reception (SL DRX); determining an SL DRX pattern for a communication on the sidelink, based on the one or more configurations for DRX, the communication comprising a service for broadcast communication, a group of UEs for groupcast communication, or a UE pair for unicast communication; and communicating with one or more other UEs on the sidelink using the determined SL DRX pattern.

Abstract: Several features pertain to computing systems equipped to perform speculative processing and configured to access device memory (e.g. non-speculative or unspeculatable memory) and non-device memory (e.g. speculative or speculatable memory). Malicious attacks may seek to obtain sensitive information from such systems by exploiting speculative code execution. Herein, techniques are described whereby sensitive data is protected from such attacks by placing the data in a page of memory not ordinarily used as device memory, and then designating or marking the page as device memory (e.g. marking the page as unspeculatable). By designating the page as unspeculatable device memory, the processor does not speculatively access the sensitive information (e.g. speculation stops once a branch is invoked that would access the page) and so certain types of attacks can be mitigated. In some examples, additional malicious attack defenses or mitigations are performed such as address space un-mapping, address space layout randomization, or anti-replay-protection.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may perform a listen-before-talk (LBT) process for a multi-slot resource that includes a plurality of consecutive slots. The UE may transmit, based at least in part on the LBT process, a first transport block within a slot of the multi-slot resource in accordance with a first sidelink grant that includes the multi-slot resource. The UE may assign one or more other slots of the multi-slot resource to a second sidelink grant for transmitting a second transport block. 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 a sidelink carrier aggregation configuration including a configuration for sidelink radio link failure (RLF) detection by: selecting one or more sidelink carriers, detecting a sidelink carrier failure associated with a failed sidelink carrier from among the one or more sidelink carriers, and recovering from the sidelink carrier failure in accordance with a reselection of at least one of the one or more sidelink carriers from among one or more candidate sidelink carriers. The UE may transmit a sidelink communication in accordance with the one or more sidelink carriers. Numerous other aspects are described.

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.
