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 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.

Abstract: Methods and apparatus are provided for seamless handover of a User Equipment (UE) between base stations using dual connectivity. The UE receives an indication of a handover of the UE from a source Base Station (BS) to a target BS, wherein the source BS and the target BS are associated with the same Radio Access Technology (RAT). The UE allocates a portion of UE resources for initiating a handover procedure with the target BS, while maintaining connectivity with the source BS. The UE terminates connectivity with the source BS after completion of the handover procedure, wherein the UE is connected to both the source BS and the target BS during at least a portion of the handover procedure.

Abstract: Neutral host networks may offer one or more different services via one or more different service providers, but user equipment (UE) may not necessarily know which services/service providers are offered by the neutral host networks. Accordingly, nodes of the neutral host networks (e.g., an access point, such as an evolved Node B (eNB)) may transmit service discovery information (SDI) to advertise the one or more services or service providers offered by the node and/or the neutral host network. Thus, a UE can receive the SDI via broadcast by the node, dedicated message from the node, etc., and can accordingly present at least a portion of the SDI or determine whether to connect to the node or another node of the neutral host network based at least in part on the SDI.
Abstract translation: 中立主机网络可以经由一个或多个不同的服务提供商提供一个或多个不同的服务，但是用户设备（UE）可能不一定知道中性主机网络提供哪些服务/服务提供商。 因此，中性主机网络（例如，诸如演进节点B（eNB）的接入点）的节点可以发送服务发现信息（SDI）以通告由节点提供的一个或多个服务或服务提供商和/或 中性主机网络。 因此，UE可以通过节点的广播，来自节点的专用消息等接收SDI，并且可以相应地呈现SDI的至少一部分，或者确定是连接到中性主机网络的节点还是另一节点 至少部分基于SDI。
