Abstract: A user equipment (UE) may monitor a downlink frequency position to detect a synchronization block (SSB) from a cellular base station. When monitoring the downlink frequency position, the UE may be configured to use at least one step size in calculating a SSB frequency position. The UE may determine a subcarrier spacing (SCS) used by the cellular base station in response to monitoring the downlink frequency position, and the subcarrier spacing for one or more SSB transmissions may be determined at least in part based on the step size used in calculating the SSB frequency position. The UE may then utilize the determined subcarrier spacing of the one or more SSB transmissions in communicating with the cellular base station.

Abstract: A wireless communication system may use higher layer signaling to send transmission configuration indicator (TCI) parameters for a frequency band comprising the 52.6 GHz to 71 GHz range. A DCI message may be used to indicate an enabled TCI state for a channel occupancy time (COT). The wireless communication system may apply the enabled TCI state for the COT as indicated in the DCI message.

Abstract: Disclosed are embodiments for a request and response signaling between first and second user equipment (UE) via a PC5 link for configuring inter-UE coordination. In some embodiments, request signaling entails a first UE identifying a transmit resource pool of the first UE to be sensed or evaluated by the second UE; instructing the second UE to report information indicating a quantity of resources; and instructing the second UE to evaluate the resources to be reported. In other embodiments, response signaling entails a first UE receiving from the second UE a request signal for inter-UE coordination; indicating a set of one or more resources, in which the set is indicated as corresponding to whitelist, blacklist, or collision list; and providing a validity time for resources indicated.

Abstract: The present application relates to devices and components including apparatus, systems, and methods to perform SRS transmission when a UE supports SRS Tx antenna port switching. In an example, a determination is made about whether a scheduled SRS transmission impacts a scheduled DL reception given the SRS Tx antenna port switching. If so, the SRS transmission and/or the DL reception are changed. In a further example, the UE can supports an SRS TA capability in conjunction with the SRS Tx antenna port switching capability. In this example, SRS TA can be applied to a scheduled SRS transmission.

Abstract: A user equipment (UE) is configured to perform measurements during two or more measurement gaps (MGs). The UE receives a MG configuration, wherein the MG configuration includes multiple MGs and MG conflict resolution information, determines whether a conflict exists between two or more of the MGs, selects at least one of the two or more MGs that have the conflict based on the MG conflict resolution information and performs signal measurements during the selected at least one of the two or more MGs that have the conflict.

Abstract: Switching schemes at a mobile device may include, in response to being within range of a transmission and reception point (TRP) of a plurality of TRPs associated with a high speed train (HST), decoding a communication received from a network. The communication may include a first radio resource control (RRC) information element (IE) having an HST configuration associated with an HST scheme. The HST configuration may be applied to thereby operate using the HST scheme. In response to being out of range of the plurality of TRPs associated with the HST, a communication received from the network may be decoded. The communication may include a second RRC IE having a non-HST configuration associated with a non-HST scheme. The non-HST configuration may be applied to thereby operate using the non-HST scheme.
