Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may identify a sidelink bandwidth part configuration for a plurality of sidelink carriers, wherein the sidelink bandwidth part configuration configures one or more sidelink bandwidth parts for each sidelink carrier of the plurality of sidelink carriers. The UE may identify at least one selected sidelink carrier selected from the plurality of sidelink carriers and an active sidelink bandwidth part for each of the at least one selected sidelink carrier from the one or more sidelink bandwidth parts configured for the at least one selected sidelink carrier. The UE may communicate with another UE in the active sidelink bandwidth part on each of the at least one selected sidelink carrier. Numerous other aspects are described.

Abstract: Apparatus, methods, and computer-readable media for sidelink discontinuous reception (DRX) management for groupcast and broadcast are disclosed herein. A transmitter user equipment (UE) may determine one or more adjustments to a sidelink DRX configuration or DRX operation based on one or more factors of the transmitter UE, and transmit, to a receiver UE over a sidelink channel, during at least a portion of a sidelink DRX active duration, a first message comprising an indication of the one or more adjustments to the sidelink DRX configuration or DRX operation. A receiver UE may receive, from a transmitter UE sent to multiple UEs over a sidelink channel, during a portion of a sidelink DRX active duration, a first message comprising an indication of one or more first adjustments to a sidelink DRX configuration or DRX operation, and determine whether to respond to the indication based on parameters of the receiver UE.

Abstract: Aspects described herein relate to sidelink transmissions. In an example, a first user equipment (UE) may receive, from a network entity, a first sidelink grant for a transmission between the first UE and a second UE; communicate the transmission according to the first sidelink grant to the second UE; determine initiation of a sidelink round trip timer subsequent to communicating the transmission to the second UE; and initiate an inactive mode for the first UE based on a second grant not being received from the network entity before completion of a duration of a sidelink retransmission timer that was initiated upon completion of a duration of the sidelink round trip timer, the first UE being configured out of an ON duration of a discontinuous reception (DRX) cycle, and an inactivity timer expiring before completion of the duration of the sidelink retransmission timer.

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.
