Abstract: Some aspects of this disclosure relate to apparatuses and methods for supporting the transmission of phase tracking reference signals (PTRS) based on an association between one or more PTRS ports and one or more demodulation reference signals (DMRS) ports for a user equipment (UE) having multiple uplink (UL) antenna elements. The UE can receive a downlink control information (DCI) including an association indication contained in an association field of the DCI to indicate an association between one or more PTRS ports and one or more DMRS ports. The association field can have a bit width determined based on an antenna architecture of the UE including the number of UL antenna elements. The UE can further determine a DMRS port associated with a PTRS port based on the association indication contained in the association field and the antenna architecture.

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: The present disclosure is directed to AP-SRS triggering offset enhancement for further enhanced MIMO. User equipment (UE), base stations, apparatus, methods, computer-readable memory media, and computer program products are disclosed. The UE may be configured to receive an offset information associated with AP-SRS transmission of the UE; determine a slot offset associated with the AP-SRS transmission, at least based on the offset information; determine a specific slot for the AP-SRS transmission, based on the determined slot offset; and perform the AP-SRS transmission in the determined specific slot.

Abstract: Beam determination refers to a set of procedures for an access node (AN) and a user equipment (UE) to select from among downlink communication beams and/or uplink communication beams for downlink and/or uplink communications, respectively. Often times, the downlink communication beams can include one or more downlink control channels, for example, a Physical Downlink Control Channel (PDCCH) and/or a Physical Downlink Shared Channel (PDSCH), to provide downlink reference signals, such as channel-state information reference signals (CSI-RSs), to the UE. The AN can execute various exemplary downlink beam scheduling procedures to control the transmission of the downlink reference signals, such as the CSI-RSs to provide an example, over the downlink communication beams. In some embodiments, the UE can utilize the CSI-RSs to perform beamforming failure detection (BFD) and beamforming failure recovery (BFR) in the wireless networks.

Abstract: Some aspects of this disclosure relate to apparatuses and methods for implementing designs for configurations of resource elements to carry reference signals for a user equipment (UE). A reference signal can be processed by the UE according to the configuration of resource elements to carry reference signals. The configurations can be determined by the base station, and received from the base station by the UE. The base station determines the configurations based on information or parameters provided by the UE, e.g., a coherence bandwidth of the channel, a coherence time of the channel, a preference associated with channel status information reference signal, or a preference associated with demodulation reference signal for the UE.

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.
