Abstract: Described are processing time approaches to simultaneous multi-cell PUSCH/PDSCH scheduling with a single DCI (downlink control information) in a wireless communication system. In various approaches, simultaneously scheduling a plurality of physical downlink shared channels (PDSCH) through a single DCI transmitted via a physical downlink control channel (PDCCH) occurs, wherein each of the plurality of PDSCHs is associated with a respective cell in a plurality of cells. The approaches further include transmitting data to or receiving data to a user equipment (UE) based on the scheduling information, wherein the plurality of PDSCHs occurs no earlier than a time offset following the PDCCH. In other aspects, a hybrid automatic repeat request-acknowledgement (HARQ-ACK) is received via a physical uplink control channel (PUCCH), the HARQ-ACK having been sent by a user equipment (UE) in response to one of the plurality of PDSCHs, wherein the HARQ-ACK is sent no earlier than a time offset following a reference time in one of the plurality of PDSCHs. In other aspects, transmitting data to or receiving data to a user equipment (UE) is based on the scheduling information, wherein the plurality of PDSCHs occurs no earlier than a time offset following the PDCCH, the time offset being configured to permit analog beam switching by a user equipment (UE).

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: Some embodiments include a system, apparatus, article of manufacture, method, and/or computer program product and/or combinations and sub-combinations thereof, for implicit power saving operations for a network-controlled repeater (NCR) in a wireless network. Some embodiments include an NCR that can receive a Downlink Control Information (DCI) format including a first Physical Downlink Control Channel (PDCCH) monitoring periodicity, KS1, and operate in an On-state for a duration of KS1. The NCR can detect a skipped PDCCH monitoring periodicity, and operate in an Off-state for a duration corresponding to the skipped PDCCH monitoring periodicity. In some embodiments, the NCR operates with a carrier component (CC) with unpaired spectrum supporting slot configurations time division duplex (tdd)-uplink (UL)-downlink (DL)-ConfigurationCommon or tdd-UL-DLConfigurationDedicated. The NCR can detect from a System Information Block (SIB), a flexible orthogonal frequency division multiplexing (OFDM) symbol, and operate in an Off-state for a duration of the flexible OFDM symbol.

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.
