Methods, systems, and devices for wireless communications are described. A network entity may configure one or more user equipments (UEs) with cell group configuration information for a single cell group or multiple cell groups. The configuration information may include parameters for each cell in the one or more cell groups. The configuration information may include a set of parameters for multiple candidate roles for each cell in the cell group. The network may then dynamically switch, update, or activate, cell groups, and may dynamically switch transmission reception points (TRPs) in a cell group from one role to another via dynamic signaling (e.g., level 1 (L1) or level 2 (L2) signaling). Additionally, or alternatively, the network may activate, deactivate, add, or remove, individual cells or cell groups from a set of configured cells via L1 or L2 signaling.

Group configuration for inter-cell mobility in multi-transmission reception point deployments

A wireless communication device can activate a discontinuous reception (DRX) mode having first inactive and active time periods allowing a user equipment (UE) to communicate sidelink control signals to another UE. The UE may receive a message from the another UE indicating an upcoming second active time period and second active time period duration for transmitting the sidelink control signals. The UE may transmit the sidelink control signals to the another UE during the second active time period duration after receiving the message from the another UE. Other aspects, features, and embodiments are also claimed and described.

Managing discontinuous reception in sidelink relay

Methods, systems, and devices for wireless communications are described. A user equipment (UE) may be configured to receive, from a first serving cell, Layer 3 (L3) control signaling indicative of multiple sets of parameters for primary serving cell and secondary serving cell operation. The UE may receive, from the first serving cell, via Layer 2 (L2) control signaling indicating an activation of a second serving cell at the UE and an indication that specifies that the second serving cell is to be activated as a primary serving cell. The UE may then communicate with the second serving cell as the primary serving cell based on receiving the second signaling and in accordance with a set of parameters from the multiple sets of parameters indicated by the L3 control signaling.

Techniques for layer 2 signaling for layer 1 and layer 2 mobility

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, in a downlink control information, a bit map identifying a plurality of feedback indicators for a plurality of uplink transmissions, wherein the plurality of feedback indicators includes more than one acknowledgment and/or negative acknowledgment; and retransmit one or more of the plurality of uplink transmissions based at least in part on receiving the bit map identifying the plurality of feedback indicators. Numerous other aspects are provided.

Consolidated feedback indication and feedback transmission

This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for enhanced signaling related to beam failure prediction. A user equipment (UE) predicts a beam failure condition prior to a number of beam failure instances within a time period reaching a configured threshold number of beam failures. The UE transmits an indicator of the predicted beam failure condition to a serving cell. The indicator may include a request for a change to a beam failure detection reference signal (BFD-RS) or to UE scheduling. The serving cell transmits a notification of a change to the BFD-RS or to UE scheduling in response to the indicator. The UE may continue to monitor for a beam failure condition based on the change or may adjust reception during a predicted duration of the beam failure based on the change.

Enhanced signaling for beam failure detection reference signal with UE predicted beam failure

A method of wireless communication at a UE is disclosed herein. The method includes transmitting, at a first time instance, an indication of a first measurement on at least one DL-RS associated with a first cell, where the first cell is included in a L1 mobility configured cell set or a L2 mobility configured cell set. The method includes receiving, at a second time instance after the first time instance, an estimated TA associated with the first cell. The method includes performing a second measurement on the at least one DL-RS. The method includes accepting or rejecting the estimated TA for communication with the first cell based on at least one of the first measurement or the second measurement.

Timing advance validation techniques for L1/L2 inter-cell mobility

A configuration to allow for the transmission of system information on different beams, where different transmission parameters may be utilized for different beams. The apparatus transmits system information on a first beam. The apparatus transmits the system information on a second beam. The system information is transmitted using different parameters for the first beam and the second beam or comprises different system information content for the first beam and the second beam.

Beam specific RMSI transmission

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine a status of a repetition procedure associated with a radio resource control (RRC) connection request message of a four-step random access channel (RACH) procedure. The UE may invoke an activity state of an RRC connection setup message monitoring procedure based at least in part on the status of the repetition procedure. Numerous other aspects are described.

Invoking an activity state of a radio resource control connection setup message monitoring procedure

Methods, systems, and devices for wireless communications are described that provide for interference-aware beam failure detection procedures. One or more beam failure parameters may be adjusted based on a likelihood of temporary interference being present for a communications beam. The beam failure parameters may include beam failure indication (BFI) counts or count thresholds that may be adjusted based on a likelihood of BFIs being the result of temporary interference. Additionally or alternatively, one or more measurement thresholds that trigger a BFI may be adjusted based on a likelihood of a presence of temporary interference.

Techniques for interference-based beam failure detection

Methods, systems, and devices for wireless communications are described. In one aspect, a first user equipment (UE) may transmit an indication of non-preferred resources to a second UE and an indication of an amount of transmit power reduction for the second UE to observe for a sidelink transmission on the non-preferred resources. In another aspect, a first UE may transmit an indication of an amount of transmit power reduction for a second UE to observe for a sidelink transmission on conflicting resources (e.g., resources reserved by the second UE and a third UE). Because the second UE may transmit on the non-preferred resources or the conflicting resources with reduced power (e.g., rather than suppressing transmissions on the non-preferred resources or the conflicting resources), the utilization of the non-preferred resources or the conflicting resources may be improved.

Transmit power adjustment based on inter-user equipment coordination

Methods, systems, and devices for wireless communications are described to support inclusion of layer 1 (L1) or layer 2 (L2) cell mobility information within a layer 3 (L3) handover command. A base station may transmit, to the UE, signaling indicating for the UE to perform a measurement on a first set of cells. The UE may perform the measurement on the first set of cells and may transmit, to the base station, an indication associated with the measurement on the first set of cells. In response to the indication, the base station may transmit, to the UE, an L3 handover command, where the L3 handover command may include L1 or L2 cell mobility information, such as an indication of a second set of cells that the UE is to use for L1 or L2 cell mobility after completing the L3 handover command.

Techniques for providing cell mobility information during handover

Certain aspects of the present disclosure provide techniques for application of a repetition factor to uplink (UL) control channels. A method that may be performed by a user equipment (UE) includes receiving, on a downlink (DL) control channel, an indication of a configuration for repetition of a UL control channel scheduled by the DL control channel and another UL control channel, wherein the configuration is applied for repetition of the other UL control channel after a configured time period starting from reception of the DL control channel; and transmitting the repetition of the UL control channel and the repetition of the other UL control channel in accordance with the configuration.

Timing considerations for dynamic indication of uplink (UL) channel repetition factors

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a base station, a beam failure detection reference signal (BFD-RS). The UE may determine, autonomously at the UE based at least in part on the BFD-RS, a beam failure instance (BFI) count for different types of BFI including BFI noise and BFI interference. The UE may detect a beam failure based at least in part on the BFI count satisfying a threshold. Numerous other aspects are described.

Determining a beam failure instance count for beam failure detection

Methods, systems, and devices for wireless communications are described. Wireless devices may be configured to support techniques for bi-directional discontinuous reception (DRX) alignment and centralized DRX alignment. In the context of bi-directional DRX alignment, DRX configurations at two respective user equipments (UEs) are first established in a first direction, and then DRX configurations are then established in the reverse direction based on the previously-established DRX configurations. In particular, DRX configurations in the reverse direction may be selected such that the Uu and sidelink DRX configurations are aligned at the respective UEs and across the UEs. Comparatively, in the context of centralized DRX alignment, a master base station receives 'candidate' Uu and sidelink DRX configurations for multiple UEs, and selects Uu and sidelink DRX configurations for each UE from the sets of candidate DRX configurations in order to ensure DRX alignment across the respective UEs.

Discontinuous reception alignment for wireless communications

A method of wireless communication at a UE is disclosed herein. The method includes receiving a L1 or L2 mobility cell configuration for a set of multiple cell groups. Each cell group comprises multiple cells. Cell groups within the set of multiple cell groups are able to be activated or deactivated for L1 or L2 mobility. The method further includes receiving L1 or L2 signaling indicating a PCG from one or more activated cell groups, the PCG including a cell that serves as a SpCell.
