Abstract: A delta configuration is signaled for handover of a wireless communication device (e.g., a user equipment, UE) from a first form of connectivity to a second form of connectivity. For example, a UE with master cell group (MCG) connectivity may be handed-over to multiple radio access technology-dual connectivity (MR-DC). In some examples, a UE with standalone (SA) connectivity may be handed-over to non-standalone (NSA) connectivity (e.g., dual connectivity). In conjunction with this handover the UE may be signaled as to whether the UE is to reuse a configuration from the first connectivity mode during the second connectivity mode.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first base station may determine collision avoidance information for avoiding collisions of physical random access channel communications from one or more user equipment. The collision avoidance information may include subcarrier spacing information and/or beam correspondence information. The first base station may transmit the collision avoidance information to a second base station. Numerous other aspects are provided.

Abstract: Aspects of the present disclosure relate to wireless communications, and more particularly, to procedures for supporting conditional new radio (NR) secondary node (SN) addition and change by using conditional handover (CHO) procedures. A method that may be performed by a user equipment (UE) includes receiving, from a master node (MN), configuration information, identifying a set of candidate cells for a conditional addition or change of a SN for a the UE based on execution criteria, detecting the execution criteria is met for one of the candidate cells, and taking action to add or change to the candidate cell as an SN based on the detection.

Abstract: Certain aspects of the present disclosure provide techniques for detecting false base stations and transmissions therefrom based on silent periods during which legitimate base stations are to refrain from transmitting at least certain downlink transmissions on at least some downlink resources.

Abstract: Certain aspects of the present disclosure provide techniques for performing radio link monitoring (RLM) and radio link failure procedures in multiple-TRP (mTRP) communications, wherein the first TRP is part of a first cell group comprising the first TRP and one or more additional TRPs. The techniques include a method of wireless communication by a user equipment (UE), comprising establishing a plurality of radio links between the UE and a first transmission reception point (TRP) and a second TRP, determining an RLM resource of a first radio link of the plurality of radio links, monitoring the first radio link according to the determined RLM resource, detecting an RLF of the first radio link, determining that the first TRP is associated with the RLF of the first radio link based on the RLM resource of the first radio link, and transmitting an RLF notification indicating the RLF of the first radio link.

Abstract: This disclosure provides systems, methods and apparatuses for listen-before-talk (LBT) failure-based channel congestion measurement and recovery triggering. In one aspect, a user equipment (UE) may determine an LBT metric based on a result of attempting to perform an uplink transmission in connection with an LBT procedure. For example, the UE may determine an absolute quantity of LBT failures, a ratio of unsuccessful uplink transmissions to total uplink transmission attempts, an absolute quantity of LBT successes, or another type of LBT metric. The UE may trigger a recovery action, such as a radio link failure (RLF) recovery action or a bandwidth part switch, based on determining that the LBT metric satisfies a threshold.

Abstract: Aspects described herein relate to receiving multiple synchronization signal blocks (SSBs) from a target cell over a measurement time window. A repeating beam index for one or more of the multiple SSBs can be identified based at least in part on a determination of a repeat parameter indicating a number of beams in a SSB pattern for the target cell. A beam set of the one or more of the multiple SSBs determined to have the same repeating beam index can be associated. One or more parameters of the one or more of the multiple SSBs of the beam set can be measured and reported.

Abstract: A configuration to enable a UE to obtain access to an unlicensed frequency channel of the unlicensed frequency spectrum in the event of channel access failures. The apparatus receives a configuration from a first base station to perform a conditional handover. The apparatus determines a first unlicensed frequency channel is unavailable for a transmission to the first base station or from the first base station. The apparatus switches from the first unlicensed frequency channel to a second cell for communication through the second cell in the conditional handover upon receiving the configuration and upon determining that the first unlicensed frequency channel is unavailable for the transmission.

Abstract: Certain aspects relate to methods and apparatus for conveying system information by a base station, comprising broadcasting a first system information common to each cell of a group of cells in an area and broadcasting a second system information that can vary between cells in the group of cells, wherein the second system information is broadcast more frequently than the first system information.
