Abstract: Methods, systems, and devices for wireless communications are described. In some systems, a first user equipment (UE), a second UE, and a network entity may support one or more configuration- or signaling-based mechanisms according to which the network entity may activate sidelink carrier aggregation (CA) between the first UE and the second UE during, as part of, or in association with a switch from direct communication between the first UE and the network entity to indirect communication between the first UE and the network entity via the second UE. In some examples, the configuration- or signaling-based mechanisms supported by the first UE, the second UE, and the network entity may be associated with whether the second UE (e.g., the relay node) is in a Radio Resource Control (RRC) connected state, an RRC idle state, or an RRC inactive state.

Abstract: A network access node including a transceiver coupled to a sidelink receiver user equipment (UE) (or to a sidelink transmitter UE) is disclosed. The network access node may obtain a network access interface discontinuous reception (DRX) slot offset value (or a sidelink interface DRX slot offset value) corresponding to a shift in a network access interface DRX Active state start time (or a sidelink interface DRX Active state start time) of the receiver UE. The shift may configure an alignment of a sidelink interface DRX Active state start time (or the network access interface DRX Active state start time) with the network access interface DRX Active state start time (or the sidelink interface DRX Active state start time). The network access interface DRX (or sidelink interface DRX) slot offset value may be transmitted to the receiver UE.

Abstract: Methods, systems, and devices for wireless communications are described. For example, the described techniques provide for configuring sidelink beam failure detection reference signals for determining beam failures on a sidelink between a first sidelink user equipment (UE) and a second sidelink UE. The first UE may determine a first set of sidelink beam failure detection reference signals to transmit to the second UE and a second set of sidelink beam failure detection reference signals to receive from the second UE. The first UE may transmit the first set to the second UE using a set of sidelink transmit beams. The first UE may further monitor for the determined second set using a set of sidelink receive beams. Based on the first and second set of sidelink beam failure detection reference signals, the first and second UE may communicate over the sidelink.

Abstract: Certain aspects of the present disclosure provide techniques for air interface and sidelink discontinuous reception alignment for inactive/idle user equipment. A method performed by a user equipment (UE) includes receiving, from a network at a first user equipment over an air interface, discontinuous reception (DRX) configuration assistance information, and transmitting, from the first user equipment to a second user equipment via a sidelink interface, the DRX configuration assistance information. The method may further include receiving, from the second user equipment at the first user equipment via the sidelink interface, sidelink DRX configuration information, wherein the sidelink DRX configuration information is based on the DRX configuration assistance information, and transmitting, from the first user equipment to the network over the air interface, the sidelink DRX configuration information. The method may include receiving, from the network at the first user equipment, modified air interface DRX configuration information for the first user equipment.

An example method at a UE may include receiving, from a first base station, a CHO configuration comprising one or more CHO candidate cell configurations associated with a second base station and one or more execution conditions associated with the first base station and including one or more CHO measurements, the one or more CHO measurements comprising one or more L1 beam or cell specific measurements or one or more L3 beam specific measurements. The example method may further include detaching from a first cell associated with the first base station and synchronizing with a second cell associated with the second base station based on the one or more CHO measurements satisfying the one or more execution conditions, the second cell being one cell associated with the one or more CHO candidate cell configurations.

Abstract: Aspects of the present disclosure relate to wireless communications, and more particularly, to mobility techniques that allow for mobility of a user equipment (UE) between a set of cells. A method that may be performed by a UE includes receiving signaling configuring the UE with a set of cells that support physical (PHY) layer or medium access control (MAC) layer mobility signaling and with a measurement configuration for the set of cells, reporting, to a network entity, measurements for at least some of the set of cells in accordance with the measurement configuration, and receiving, from the network entity, PHY layer or MAC layer mobility signaling to move the UE to one of the cells in the set, wherein the mobility signaling is based, at least in part, on the reported measurements.

Abstract: Methods, systems, and devices for wireless communications are described to support transmission of a resource modification information request from a user equipment (UE) to a base station, where the resource modification request may request an increased density of uplink transmission occasions. For example, the resource modification request may request an increase from a first density of uplink transmission occasions configured for the UE. The resource modification request may include a request for a decreased periodicity of uplink transmission occasions, an increased number of groups of repetitions for uplink transmission occasions, an increased number of resource blocks for uplink transmission occasions, or an increased modulation coding scheme for uplink transmission occasions. The base station may receive the resource modification request and may transmit a message to the UE, which may indicate a modified or new uplink grant configuration for uplink transmission occasions having a higher density (e.g., a second density).

Abstract: Methods, systems, and devices for wireless communications are described. Generally, the described techniques provide for a user equipment (UE) receiving a configuration for a plurality of dormancy modes for a secondary cell group (SCG) dormancy state. The UE may receive the configuration and determine to transition to a SCG dormancy mode based on the configuration. The UE may enter the dormancy mode and communicate with a master cell group (MCG), the SCG, or both based on the configuration for the dormancy mode. The UE may perform radio resource management, radio link management, and beam failure detection procedures while in SCG dormancy mode. The UE may also perform layer 1 measurements and reporting, timing configuration procedures, power control procedures, and the like depending on the dormancy mode.

In some aspects, a user equipment (UE) may receive information identifying a sidelink discontinuous reception (DRX) configuration, that is different from an access link DRX configuration, associated with operation in a sidelink communication deployment. The UE may monitor a physical downlink control channel (PDCCH) discontinuously using the sidelink DRX configuration. Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communications are described. In some systems, a user equipment (UE) may transmit a number of channel state information (CSI) reports for a CSI reporting procedure as part of a beam management procedure. The UE may transmit a first number of CSI reports of the CSI reporting procedure to the base station using a first set of transmission parameters associated with a first reliability level. The base station may transmit a control message to the UE indicating a second set of transmission parameters associated with a second reliability level and the UE may transmit a second number of CSI reports of the CSI reporting procedure to the base station using the second set of transmission parameters.
