Abstract: Systems and methods for determining a timing of a random access channel (RACH) occasion (RO) used to transmit a contention free random access (CFRA) preamble triggered by the receipt of an physical downlink control channel (PDCCH) order in a PDCCH are disclosed herein. A user equipment (UE) receives the PDCCH order and determines a timing offset value between the RO and a signal (e.g., a synchronization signal block (SSB), the PDCCH, a reference signal, etc.) to be used as a timing source. The UE also determines the arrival time of the signal to be used at the timing source. The UE then determines a time of the RO (during which the CFRA preamble will be transmitted) according to the arrival time and the timing offset value. Timing advance (TA) value(s) may also be accounted for as part of such a determination.

Abstract: A wake up signal scheme between a network and a user equipment (UE) operating in a Discontinuous Reception (DRX) state. The UE monitors a wake up signal (WUS) occasion to determine whether a WUS is received during the WUS occasion, when the WUS is received, determines whether the WUS identifies the UE, when the WUS is received and identifies the UE, monitors an OnDuration of a Discontinuous Reception (DRX) cycle corresponding to the WUS and when the WUS is not received or the WUS does not identify the UE, remains in a sleep state during the OnDuration corresponding to the WUS.

Abstract: A user equipment (UE) is configured to receive synchronization signal blocks (SSBs) from a wireless network to estimate frequency and timing errors. The UE receives a quasi co-location (QCL) configuration between a synchronization signal block (SSB) and at least one of a further SSB or a tracking reference signal (TRS), receives the SSB and the at least one of the further SSB or the TRS and estimates a frequency and timing error for the SSB by combining, based on the QCL configuration, measurements for the SSB and measurements for the at least one of the further SSB or the TRS.

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 user equipment (UE) receives reference signals during a discontinuous reception (DRX) cycle to perform frequency and timing tracking or automatic gain control (AGC). The UE receives configuration information corresponding to a reference signal that is to be transmitted to a user equipment (UE) when the UE is in a first operating state, receives the reference signal from a cell of a network when the UE is in the first operating state, performs one of frequency and timing tracking or automatic gain control (AGC) using the reference signal and receives a signal from the cell during a time window that the UE is scheduled to utilize an active mode of data exchange processing.
