Abstract: User equipment (UE) operation in a single frequency network (SFN). The UE may receive one or more transmission configuration indication (TCI) states corresponding to one or more downlink resources, receive a demodulated reference signal (DMRS) wherein the DMRS is quasi co-located (QCLed) with one or more channel state information reference signal (CSI-RS) from multiple cells of a SFN and quasi co-location (QCL) information is included in the one or more TCI and determine a time and frequency offset corresponding to each of the multiple cells based on the CSI-RS.

Abstract: Systems and method are provided for determining access link direction beams for smart repeaters (SMRs). An SMR may be configured with a set of SMR transmission beam indicator (TBI) state (SMR-TBI State) configurations. The SMR-TBI State configurations in the set respectively comprise an SMR-TBI State identifier (ID), a cell index, and a reference signal associated with a beam for an access link between the SMR and a user equipment (UE). The SMR may receive, through a backhaul link from a base station, an indication of one or more active SMR-TBI States. For at least one of the one or more active SMR-TBI States, the SMR may forward a signal between the base station and the UE using the beam associated with the reference signal in a corresponding SMR-TBI State configuration.

Abstract: Some embodiments of this disclosure include apparatuses and methods for uplink panel selection with power saving. In some embodiments, user equipment (UE) may experience a positional change. In response, the UE may deactivate a first communication panel to save power and activate a second communication panel. The UE may then transmit a status message to a communication node indicating the activation and/or deactivation. The node may then register this activation and/or deactivation. In some embodiments, the node may monitor uplink slots from the first and second communication panel to identify the activation and deactivation. For example, if the node detects an absence of an uplink signal within a slot threshold, the node may identify the panel as being deactivated. The node may establishing communications with another panel based on a detected signal and/or the status message.

Abstract: Some aspects of this disclosure relate to apparatuses and methods for supporting channel state information (CSI) report configuration for measuring time-domain channel properties (TDCP) of a channel between a user equipment (UE) and a base station. The UE can receive a CSI report configuration from the base station to configure a CSI report, where the CSI report configuration includes an indicator related to a number of tracking reference signal (TRS) resource sets for measuring TDCP of the channel. A TRS resource set can include at least two symbols in a slot for CSI reference signals (CSI-RS), and the slot is repeated to form multiple slots having a periodicity. The UE can further configure the number of TRS resource sets based on a CSI resource setting associated with the CSI report configuration, monitor the configured number of TRS resource sets to perform CSI report measurements.

Abstract: A method, UE and integrated circuit for reporting RSTD values to a network. A user equipment (UE) is configured to establish a connection to a network, the network comprising a first cell and a second cell. The UE receives a positioning reference signal from each of the first and second cells, determines a frequency band for each of the positioning reference signals, determines reference signal time difference (RSTD) values from measured time offsets between the positioning reference signals from the first and second cells, determines RSTD reporting values based on at least the RSTD values and the determined frequency bands and transmits an indication of the RSTD reporting values to the network.
