Abstract: Apparatuses, systems, and methods may use an smtc information element or an smtc2-LP information element to calculate timing of a first measurement period to evaluate a serving cell while the UE is in idle mode or inactive mode. Additionally, apparatuses, systems, and methods may use the smtc information element or the smtc2-LP information element to calculate timing of a second measurement period to evaluate intra-frequency cells while the UE is in idle mode or inactive mode.

Abstract: A terminal may include a transmitter that transmits, to a base station, a terminal capability indicating support for a first type of measurement configuration or a second type of measurement configuration. The terminal may include a receiver that receives, from the base station, network configuration information representative of a mapping between the first type of measurement configuration and the second type of measurement configuration. The terminal may include a processor that, based on the mapping, transforms the first type of measurement configuration to the second type of measurement configuration or transforms the second type of measurement configuration to the first type of measurement configuration. The network configuration information may be based on an independent frequency range (FR) measurement and a network preference included in the terminal capability.

Abstract: The present application relates to wireless devices, and more particularly to apparatus, systems, and methods for radio link monitoring beam management in 5G-New Radio (NR) for Ultra-Reliable Low-Latency Communication (URLLC). In one embodiment, a method for signal quality monitoring in a wireless system is disclosed, comprising: determining, by a user device, to connect to the wireless system in a high reliability mode, and determining, based on the determination to connect to the wireless system in the high reliability mode, to use, by the user device, a first pair of out-of-sync (OOS) and in-sync (IS) block error rate (BLER) threshold values and/or a first set of transmission parameters for radio link monitoring (RLM), rather than a second pair of OOS and IS BLER threshold values or a second set of transmission parameters that are configured for use in a non-high reliability mode.

Abstract: A wireless device may establish communication with a network node and determine a relationship between transmission configuration indication (TCI) and bandwidth part (BWP). The wireless device may then receive an indication of one of TCI or BWP from the network node followed by determining the other of TCI or BWP based on the indication and using the relationship between the TCI and BWP. Finally, the wireless device may perform downlink communication using the indicated one of TCI or BWP and determined other TCI or BWP. The network node may be comprised in a non-terrestrial network and may specify via RRC signaling the relationship between TCI and BWP for the wireless device. The indication of the TCI or BWP may be provided by downlink control information (DCI), medium access control (MAC) control element (CE), an inactivity timer, or RRC reconfiguration commands.

Abstract: Techniques discussed herein can facilitate the use of reference signals in active TCI switching. One example aspect is a user equipment (UE), comprising: a memory interface; and processing circuitry communicatively coupled to the memory interface and configured to: receive a physical downlink shared channel (PDSCH) message that includes an activation command indicating a target transmission configuration indicator (TCI) state; decode the activation command within a decoding period, where the decoding period is a time period allocated for the UE to decode the activation command; receive a TCI resource where the TCI resource is a reference signal; perform time and frequency tracking associated with the target TCI state according the TCI resource; and switch to the target TCI state after performing time and frequency tracking.

Abstract: The present disclosure is related to indication of simultaneous RX beams capability and related measurement resource coordination. In an embodiment, a UE is configured to receive, from a base station, a measurement configuration comprising a measurement period for performing measurements on one or more carriers. The UE is further configured to assign measurement resources to the one or more carriers based on a simultaneous RX beams capability, wherein the measurement resources comprise searchers and RX beams during each measurement occasion. The UE is further configured to determine a measurement period scaling factor for the one or more carriers based on the assigned resources. With this capability, the UE can complete L1 and/or L3 measurements and transmit a measurement report to the base station earlier.

Abstract: To support layer 1 (L1) and layer 2 (L2) centric inter-cell mobility and inter-cell multi-TRP operation, a user equipment (UE) may need to measurement the downlink reference signals from neighbor cells. To obtain these measurements, a UE may perform layer 3 (L3) measurements for one or more neighboring cells, and provide an L3 measurement report to a network node. Candidate measurement neighboring cells for L1 measurements may be identified based on the L3 measurements.
