Abstract: Techniques for dynamic sidelink waveform selection are disclosed. In an example, a user equipment (UE) may determine capabilities of the UE and at least one other UE. The UE may also dynamically select a waveform for sidelink beam training based on the capabilities. The UE may also communicate with the at least one other UE based on the selected waveform.

Abstract: User equipment associated with a legacy network may utilize a bottom-to-top search technique to identify relevant control channel samples. Generating a control channel that is configured for the bottom-to-top search technique may lead to poor performance in a single-carrier waveform, which may be disadvantageous as networks move toward New Radio. In some aspects, described herein, a base station generates a control channel that is configured to minimize gaps in the control channel, and a user equipment performs a top-to-bottom search technique to identify relevant control channel samples. By using the top-to-bottom search technique, degradation of single-carrier waveforms is reduced and efficiency is improved.

Abstract: A method, a computer-readable medium, and an apparatus are provided for wireless communication at a user equipment. The UE receives an indication from a base station that a medium access control-control element (MAC-CE) activation of a pathloss reference signal is enabled. The UE receives a MAC-CE activating the pathloss reference signal. The UE determines the pathloss reference signal based on the MAC-CE and the indication that indicates that the MAC-CE activation of the pathloss reference signal is enabled. Then, the UE estimates a downlink pathloss based on the pathloss reference signal that is activated by the MAC-CE.

Abstract: Certain aspects of the present disclosure provide techniques for reporting and responding to beam failure events based on a receiving cell restriction rule. An example method includes detecting an occurrence of a threshold number of beam failures for a connection between a UE and a set of cells; identifying a candidate beam for restoring the connection between the UE and the set of cells in response to detecting the occurrence of the threshold number of beam failures; transmitting, to one or more cells in the set of cells, a beam failure recovery (BFR) request including an identification of the candidate beam; receiving, from a cell in the set of cells, a BFR response in response to transmitting the BFR request, wherein the BFR response is received according to a restriction rule; and resuming communications with the set of cells based on the BFR response.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a central entity in an integrated access and backhaul (IAB) network may determine that a trigger condition for updating transport network layer information of an IAB node in the IAB network is satisfied, based at least in part on at least one of: a change of a donor distributed unit associated with the IAB node, a central entity change associated with the IAB node, or an establishment, release, or modification of a route including the IAB node; and provide, to the IAB node, updated transport network layer information, based at least in part on the trigger condition being satisfied. Numerous other aspects are described.

Abstract: Aspects relate to mechanisms for wireless communication devices to report a beam failure. A UE detects a beam failure with a cell. The UE transmits a beam failure recovery request including an indication of a candidate beam to a base station in response to detecting the beam failure. The base station transmits a beam failure recovery response to the UE indicating whether the beam failure recovery request is received. The UE applies the candidate beam indicated in the beam failure recovery request for a downlink channel following a predetermined number of symbols after an end of the beam failure recovery response. The UE transmits an acknowledgment (ACK) message to the base station when the beam failure recovery response is decoded. The UE applies the candidate beam indicated in the beam failure recovery request for a downlink channel following a predetermined number of symbols after an end of the ACK message.

Abstract: A configuration to enable a UE to switch beams of respective CCs based on certain factors (e.g., RTD or TCI states), and not switch the beams simultaneously. The apparatus receives, from a base station, a transmission including an indication to change at least one of a TCI state for multiple CCs, a spatial relation for the multiple CCs, or a PL RS for the multiple CCs. The apparatus switches beams in response to the transmission, where timing of the switching is based on a grouping of the multiple CCs.

Abstract: A method, an apparatus, and a computer program product for wireless communication are provided. A component carrier group may be configured for beam management, such that beam management on a first component carrier is applied to one or more second component carriers to reduce signaling overhead associated with controlling a defined group of component carriers. A user equipment may be configured to identify a group of component carriers and, when a beam failure detection reference signal is received from a base station on a first component carrier, identify a beam failure condition for the first component carrier and one or more second component carriers of the group of component carriers.
