    Abstract: Systems, methods and devices can are provided, which can include configuring one or more bandwidth parts for a secondary cell (SCell) that is in communication with a user equipment (UE). A base station transmits to a UE a first radio resource control (RRC) message including one or more configuration parameters for a first bandwidth part (BWP) associated with a secondary cell (SCell). The UE communicates a first message with the SCell via the first SCell BWP. The UE receives a second RRC message indicating a change from the first SCell BWP to a second SCell BWP to be used for SCell communications. The UE communicates a second message with the SCell via the second SCell BWP.

    Abstract: Techniques discussed herein can facilitate suspended secondary cell group (SCG) state relaxed measurements. One example aspect is a user equipment (UE) device, comprising: a memory; an antenna; a transceiver connected to the antenna; and a processor configured to: while in a dual connectivity (DC) mode where the UE is connected to a master node (MN) associated with a master cell group (MCG) and a secondary node (SN) associated with a SCG comprising a primary secondary cell (PSCell), receive a signaling from a base station (BS) comprising an indication to enter a suspended state for the secondary cell group (SCG), in response to the signaling, enter the suspended state for the SCG, while in the suspended state for the SCG, perform relaxed measurements on the PSCell; and send, to the BS, a measurement report comprising a one or more measurement results from the relaxed measurements.

    Abstract: Performing a UE-triggered lower layer-based handover may include performing measurements of source gNB CSI-RS samples associated with a source gNB. Measurements of target gNB CSI-RS samples associated with a target gNB may be performed, wherein the CSI-RS samples associated with the source gNB and the CSI-RS samples associated with the target gNB are transmitted in a burst structure. A subset of the source gNB CSI-RS samples and the target gNB CSI-RS samples may be filtered using a layer 1 or a layer 2 filter. A filtered result for each of the subset of source gNB CSI-RS samples and the subset of target gNB CSI-RS samples may be generated. Based on the generated filtered result for each of the subset of source gNB CSI-RS samples and the subset of target gNB CSI-RS samples, determining whether a handover from the source gNB to the target gNB is to occur.

    Abstract: A system for determining and reporting user equipment (UE) time gap requirement information for performing a measurement on a reference signal provided by a target base station. A UE receives a radio resource control (RRC) message from a current base station to modify a current RRC connection. The RRC configuration message may comprise sub carrier spacing (SCS) information of one or more target frequency bands of at least one target base station. The UE may then determine gap information based at least in part on the received SCS information of the one or more target frequency bands. The gap information may indicate whether a gap is needed in performing measurements on a reference signal transmitted at each of the one or more target frequency bands. The UE then transmits the gap information to the current base station.

    Abstract: Some aspects include an apparatus, method, and computer program product for facilitating control messaging for multi-beam communications in 5G wireless communication systems. Nodes of a 5G network may be generate Medium Access Control Control Elements (MAC CEs) to update User Equipment (UE) with different Component Carrier (CC) settings. The MAC CEs may update a list of CCs to reduce messaging overhead and latency. For example, a MAC CE may indicate an update for a Transmission Configuration Indication (TCI) state for a list of CCs. Similarly, a MAC CE may be used to update a spatial relation for a Sounding Reference Signal (SRS) resource set and/or a SRS resource corresponding to a list of CCs. A MAC CE may also be used to update multiple TCI codepoints having one or two TCI states in a multi-Transmission Reception Point (multi-TRP) scenario.
