Abstract: Methods and apparatus for uplink DRX and sidelink DRX are disclosed. A WTRU may receive a configuration of a hybrid automatic repeat request (HARQ) round trip time (RTT) timer. The WTRU may start the HARQ RTT timer in response to an event. The event may comprise receiving a downlink control information (DCI) that schedules a sidelink transmission. The event may comprise transmission of a sidelink control information (SCI) for the sidelink HARQ process. The event may comprise receiving HARQ feedback for a sidelink transmission. The event my comprise a pre-configured time period following a physical sidelink feedback channel (PSFCH) resource for feedback associated with a HARQ transmission. The WTRU may determine a value of a timer based on a sidelink transmission property or a sidelink transmission time.

Abstract: Methods and apparatuses for Sidelink (SL) communication are disclosed herein. A method for SL communication performed by a Wireless Transmit/Receive Unit (WTRU) may comprise determining to transmit Sidelink Control Information (SCI) over a Physical Sidelink Control Channel (PSCCH). The method may further comprise selecting one or more sub-channels from a Physical Sidelink Shared Channel (PSSCH) in which to allocate time and frequency resources for the PSCCH. The method may further comprise allocating time and frequency resources within the PSCCH in which to transmit the SCI. The allocation of time and frequency resources may be based on at least one of an SCI format type, a Layer 1 (L1) Identifier (ID), a priority, or a Quality of Service (QoS) requirement. The method may further comprise transmitting the SCI over the determined time and frequency resources.

Abstract: A method and apparatus to address changes in quality of service in a communication link between two user equipment devices includes establishing the communication link between a first user equipment device and a peer user equipment device, where the communication link services an application executing on the first user equipment. The first user equipment device monitors a current quality of service on the communication link and detects a condition wherein the current quality of service may not be met. Adjusted configuration parameters for the application and new quality of service parameters for the communication link are determined. The adjusted configuration parameters are applied to the application and the new quality of service parameters are applied to the communication link.
