    Abstract: Disclosed are methods, systems, and computer-readable medium to perform operations including: receiving downlink control information (DCI) scheduling a first physical uplink shared channel (PUSCH) transmission to be transmitted by a first antenna panel of the UE, and a second PUSCH transmission to be transmitted by a second antenna panel of the UE, receiving data indicative of at least two transmission configuration indicator (TCI) states, the at least two TCI states including a first TCI state indicating a beam of the first antenna panel for transmission of the first PUSCH transmission, and a second TCI state indicating a beam of the second antenna panel for transmission of the second PUSCH transmission, and transmitting the first PUSCH transmission using the beam of the first antenna panel and the second PUSCH transmission using the beam of the second antenna panel.

    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: Apparatuses, systems, and methods for enhancing non-PMI based CSI reporting for NC-JT in multi-TRP operations, including addressing channel CRI reporting, CQI reporting, RI reporting, and CSI processing complexity and timeline in NC-JT multi-TRP operations. For example, a UE may receive, from a base station, a configuration for a first set of CSI-RS resources for a first TRP (associated with single TRP operation), a second set of CSI-RS resources for a second TRP (associated with single TRP operation), and a third set of pairs of CSI-RS resources for the first TRP and second TRP (associated with multi-TRP operation). The UE may report, to the base station, a CRI report indicating whether the UE prefers single TRP operation from the first TRP or the second TRP, or multi-TRP operation from the first TRP and the second TRP. The CRI report may be based on the configuration.

    Abstract: Inter-cell mobility may include decoding a first radio resource control (RRC) reconfiguration message received from a first cell. The first RRC reconfiguration message may comprise a first portion of configuration information for performing a cell change to a second cell. A cell change message received from the first cell may be decoded. The cell change message may indicate that a cell change to the second cell is to be performed. A cell change acknowledgment may be encoded for transmission to the second cell. A second RRC reconfiguration message received from the second cell may be decoded. The second RRC reconfiguration message may comprise a second portion of configuration information for performing the cell change to the second cell. The second portion of configuration information may comprise a remaining portion of configuration information to perform the cell change to the second cell.
