Abstract: Methods and apparatuses for methods and apparatuses for facilitating signaling of multiple timing advance (TA) values to a user equipment (UE), facilitating the use of multiple TA values by a UE for communication with multiple transmission and reception points (TRPs), and facilitating updating of TA values in a wireless communications network. A UE comprises a transceiver and a processor operably coupled to the transceiver. The transceiver is configured to receive a first TA command that includes a first TA value and a first TA group (TAG) identifier (ID) associated with a first entity, and a second TA value and a second TAG ID associated with a second entity. The processor is configured to identify a TAG ID associated with an uplink (UL) transmission, and identify, based on the TAG ID, a TA value. The transceiver is further configured to transmit the UL transmission using the TA value.

Abstract: Methods and apparatus for user equipment (UE)-initiated channel state information (CSI) measurement and reporting. A method performed by a UE includes transmitting an indicator to request transmission of one or more CSI reference signals (RSs), receiving a downlink control information (DCI) format indicating a value of a CSI request field, and identifying a first time window. The method further includes identifying a reception time of the DCI format relative to a last symbol for transmission of the indicator, determining, based on the value, a CSI resource setting and a CSI reporting setting, and measuring, based on the CSI resource setting, the one or more CSI-RSs.

Abstract: A method of operating a user equipment (UE) includes receiving first information for a physical cell identifier (PCI) different from a serving cell PCI; receiving second information for source or measurement reference signals (RSs) for the PCI; determining, based on one or more transmission configuration indicator (TCI) states, the first information, and the second information, a reception spatial domain filter for reception of at least one of downlink (DL) RSs and channels from the PCI; and measuring, based on the first information and the second information, the measurement RS. The method further includes determining, based on the measured measurement RSs, the first information, and the second information, a beam report and transmitting the beam report for the PCI on an uplink (UL) channel. A beam refers to a spatial property used to receive or transmit a source RS or a channel.

Abstract: Methods and apparatuses for transmission configuration indication (TCI) state indication and update via dynamic signaling in a wireless communication system. A method performed by a user equipment (UE) includes receiving, in a radio resource control (RRC) signaling, a first indicator; receiving, in a medium access control (MAC) control element (CE), a second indicator; receiving scheduling information of a physical downlink shared channel (PDSCH); and receiving, based on a first or second applied TCI state, the PDSCH. The method further includes identifying, based on the first indicator, at least one of a first group or a second group of TCI states; determining, based on the second indicator, whether a first or second TCI state updates the first or second applied TCI state; and determining, based on the identification and the second indicator, whether the first and second TCI states belong to the first group or second group of TCI states.

Abstract: Methods and apparatuses for methods and apparatuses for facilitating serving cell changes based on signaling related to beam management procedures in a wireless communications network. A user equipment (UE) comprises a transceiver and a processor operably coupled to the transceiver. The transceiver is configured to receive a transmission configuration indicator (TCI) state identifier (ID) associated with a target serving cell, receive a cell switch command, and transmit, in response to reception of the cell switch command, a channel conveying a positive hybrid automatic repeat request acknowledgement (HARQ-ACK). The processor is configured to perform, based on the cell switch command, a cell switch at a time, wherein the time corresponds to a slot that starts after a cell switch application time from a last symbol of the channel conveying the positive HARQ-ACK.
