Certain aspects of the present disclosure provide techniques for inter-cell measurement and reporting. A method that may be performed by a user equipment (UE) includes sending, to a base station (BS), an indication of one or more capabilities of the UE for inter-cell signal measurements, reporting of the inter-cell signal measurements, or both. The UE may perform inter-cell signal measurement and reporting based on the one or more capabilities.

Inter-cell measurement and reporting for beam management

Various aspects of the present disclosure generally relate to wireless communication. Some aspects relate to Layer 1 or Layer 2 triggered mobility (LTM) using groups of candidate cells. Some aspects more specifically relate to performing LTM operations, such as measurement, reporting, or switching, for cells of an activated group of candidate cells for LTM. In some aspects, a user equipment (UE) may measure an activated group of candidate cells in accordance with the activated group of candidate cells being activated. For example, the UE may not measure candidate cells that do not belong to an activated group of candidate cells. In some aspects, the activated group of candidate cells may include a subset of all candidate cells configured for the UE. For example, the UE may perform measurement and reporting for the subset of candidate cells, instead of all candidate cells configured for the UE.

Lower layer triggered mobility cell grouping

Methods, systems, and devices for wireless communications are described. A first device (e.g., a user equipment) may modify logical channel prioritization based on a packet delay. The first device may receive a set of parameter values for a logical channel prioritization procedure, then select a parameter value from the set based on a packet delay for data scheduled in an uplink grant. The first device may determine the parameter value, or the first device may select the parameter value based on signaling received from a second device (e.g., a base station). In some examples, the first device or the second device may determine the parameter value based on a delay prediction or machine learning.

Techniques for data multiplexing based on packet delay

Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive control signaling indicating a set of transmission occasions usable by the UE for transmitting layer one (L1) reports. The set of transmission occasions may include a first subset of transmission occasions for transmitting beam information reports and a second subset of transmission occasions for transmitting beam information reports and corresponding antenna port information. The UE may then transmit, within a first transmission occasion of the first subset of transmission occasions, a first L1 report including a first beam information report, and may transmit, within a second transmission occasion of the second subset of transmission occasions, a second L1 report including a second beam information report and an indication of a quantity of antenna ports supported by the UE.

Techniques for indicating panel information reports via beam reporting occasions

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a network node, configuration information that indicates a configuration for monitoring beam failure detection reference signals (BFD-RSs) in a discontinuous reception (DRX) on duration. The UE may transmit, to the network node, information that is based at least in part on the BFD-RSs being monitored in the DRX on duration in accordance with the configuration. Numerous other aspects are described.

Beam failure detection reference signal monitoring for discontinuous reception

Methods, systems, and devices for wireless communications are described. The method may include a user equipment (UE) transmitting a first signal using a first waveform type. After transmitting the first signal using the first waveform type, the UE may identify a trigger event for waveform type switching by the UE and select a waveform type from among a set of waveform types based on identifying the trigger event. The UE may then transmit a second signal using the selected waveform type.

Event-triggered waveform type selection

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.
