Abstract: A configuration for an originating wireless device to transmit one or more MAC-CEs, where each of the one or more MAC-CEs include information related to the number of MAC-CEs transmitted. The apparatus transmits at least one of a plurality of related MAC-CEs to a second wireless device based on a determination of at least a first path of a plurality of paths to transmit the at least one of the plurality of related MAC-CEs. The at least one of the plurality of related MAC-CEs indicates a number of the plurality of related MAC-CEs transmitted by the first wireless device. The apparatus monitors for a response MAC-CE from the second wireless device based on a transmission of the at least one of the plurality of related MAC-CEs. The response MAC-CE corresponds to an activation of the MAC-CE transmitted to the second wireless device.

Abstract: The present disclosure provides signaling for multi-panel user equipment (MPUE) activation. The MPUE may have at least an active first panel and an inactive second panel. The MPUE may determine to activate the second panel. The MPUE may activate the second panel in response to the determination. The MPUE may transmit, from the active first panel to a base station, a status indicating that the second panel is active. The MPUE may transmit, after an activation time, an uplink transmission from the second panel to the base station.

Abstract: Certain aspects of the present disclosure provide techniques for network-assisted sidelink beam failure recovery. In certain aspects, a method performed by a base station may generally include receiving from a first UE a sidelink beam failure recovery (BFR) signal, indicating that a first communication link between the first UE and a second UE has failed; determining, based on the sidelink BFR signal, a set of resources for performing a sidelink beam failure recovery procedure to reestablish the first communication link between the first UE and the second UE; and transmitting information to the first UE and the second UE indicating the set of resources for performing the sidelink beam failure recovery procedure.

Abstract: Aspects of the present disclosure provide techniques for standalone sidelink beam failure recovery. A method performed by a first user equipment includes communicating, while operating in a sidelink discontinuous reception (DRX) mode, with a second UE on a first communications link between the first UE and the second UE; transmitting, during an awake state of the sidelink DRX mode, at least one beam failure detection reference signal of a plurality of beam failure detection reference signals associated with the first communications link, wherein a periodicity of the awake state of the sidelink DRX mode is based on a periodicity for transmitting the plurality of beam failure detection reference signals; and detecting that the first communications link between the first UE and the second UE has failed based on the at least one beam failure detection reference signal.

Abstract: Methods, apparatuses, and computer-readable storage medium for SL communications are provided. An example method may include transmitting, to a second UE, a SL BWP switching request message requesting a switch from a first BWP to a second BWP. The example method may further include receiving, from the second UE, an SL BWP switching decision message confirming the switch from the first BWP to the second BWP. The example method may further include switching from the first BWP to the second BWP upon receiving the SL BWP switching decision message. The example method may further include transmitting, to the second UE, an SL BWP switching confirmation message confirming the switch from the first BWP to the second BWP. The example method may further include reverting back to the first BWP.

Abstract: Systems and methods establishing and maintain a direct User Equipment to User Equipment communication link are disclosed. A User Equipment (UE) may receive a Sounding Reference Signal (SRS) from a neighboring UE. The UE may determine from the SRS that the UE is a good candidate for a direct link. The UE may also determine from the SRS an ID associated with the neighboring UE. The UE may send a direct link request to the UE serving gNB. The serving gNB may forward the request to a gNB serving the neighboring UE. The gNBs may negotiate a joint schedule for a beam a UE to UE beam search. The beam search may be conducted using SRS resources. The results of the beam search may be sent to the gNB and the gNB may determine a beam pair for a direct link.

Abstract: Methods, systems, and devices for wireless communications are described. In some examples, a first UE may receive an indication of first resources from a second UE. In some examples, the second UE may be a UE configured to receive a transmission from a third UE over the first resources. In some such examples, the first UE may transmit, to a fourth UE, a sidelink transmission over available resources that exclude the first resources. Additionally, or alternatively, the second UE may be a UE that received sidelink control information from the third UE indicating the resources for transmission by the third UE to a fourth UE. In some such examples, the first UE may transmit, to the second UE, a sidelink transmission over available resources that exclude the first resources.

Abstract: A user equipment (UE) may receive, from at least one of a base station or a configuring UE, a configuration of a plurality of sidelink power control parameter sets, a media access control (MAC) control element (CE) (MAC-CE) activating transmission configuration indicator (TCI) states and indicating sidelink power control parameter sets, and control information indicating a TCI state and a sidelink power control parameter set. The UE may transmit the sidelink communication in a direction based on the TCI state and with a transmission power indicated in the control information. The MAC-CE may include a joint MAC-CE or separate MAC-CEs to update or configuration of the sidelink TCI and the power control parameters.
