    Abstract: Apparatuses, systems, and methods for performing downlink signal reception with antenna panel switching in a wireless communication system. A cellular base station may receive an indication of an antenna panel activation delay from a wireless device. The cellular base station may select a scheduling offset for a transmission to the wireless device based at least in part on the antenna panel activation delay. The scheduling offset may be selected to be at least the length of the antenna panel activation delay if it is expected that the wireless device may perform antenna panel activation to receive the transmission. The cellular base station may schedule the transmission to the wireless device using the selected scheduling offset, and may perform the transmission to the wireless device at the selected scheduling offset after scheduling the transmission to the wireless device.

    Abstract: Embodiments of the present disclosure enable a user equipment (UE) to performing inter-Radio Access Technology (RAT) measurements. The UE determines whether one or more inter-RAT measurement object (MO) is configured with or without a measurement gap (MG). When the one or more inter-RAT MO is on an NR serving component carrier (CC) with the MG, the UE performs an inter-RAT measurement on the NR serving CC based on whether the MG is fully overlapped or partially overlapped with synchronization signal blocks (SSBs) of a target MO of the one or more inter-RAT MO. When the one or more inter-RAT MO is on the NR serving CC without the MG, the UE performs the inter-RAT measurement on the NR serving CC based on whether a target SSB of the target MO is within or outside an active bandwidth part (BWP) of the NR serving CC.

    Abstract: To reduce the beam reporting latency, a base station may include a sounding reference signal (SRS) indication to a wireless communication device (UE) as part of the transmission configuration information (TCI) transmitted to the UE, allowing the UE to receive a corresponding downlink signal using the same beam (or with the same beam) the UE used to transmit (or with which the UE transmitted) the SRS indicated in the TCI. The SRS may be one of multiple SRSs previously transmitted by the UE. The UE may transmit the multiple SRSs periodically and/or according to semi-persistent scheduling, or it may transmit them aperiodically. Therefore, the UE does not need to report the beam quality, and the base station may perform the necessary beam measurement(s) instead. Various parameters and conditions may be defined for the UE to support SRS-based TCI.

    Abstract: Apparatuses, systems, and methods for a wireless device to perform a method including a user equipment device (UE) exchanging communications with a base station to determine one or more scheduling profiles, such as one or more scheduling-power profiles, where a scheduling-power profile may specify one or more parameters associated with UE communication behavior, e.g., one or more constraints on UE communication behavior and/or slot scheduling of UE communications. In addition, the method may include the UE receiving a slot configuration schedule from the base station. The slot configuration schedule may be based on at least one scheduling-power profile of the one or more scheduling-power profiles. Further, the method may include the UE performing communications with the base station based on the at least one scheduling-power profile.

    Abstract: An example method for wireless communication includes: receiving, by a user device in a reduced power state, resource information for receiving a channel state information reference signal (CSI-RS) and tracking reference signal (TRS); exiting the reduced power state to receive the CSI-RS and TRS, based on the resource information; synchronizing with a base station, based on the received CSI-RS and TRS, to receive a downlink control information message; receiving paging information in a first physical downlink shared channel (PDSCH) transmission based on the received downlink control information message; determining whether there is paging information in the first PDSCH transmission for the user device; starting a Random Access Channel (RACH) procedure to make a Radio Resource Control (RRC) connection, based on determining that there is paging information for the user device; and returning to the reduced power state, based on determining that there is not paging information for the user device.
