    Abstract: Methods and apparatuses for user equipment (UE) initiated reporting in a wireless communication system. A method of operating a UE includes receiving first information related to resources for a physical uplink shared channel (PUSCH); receiving second information related to (i) beam measurement resources and (ii) a beam report configuration; and receiving third information related to a condition to transmit a beam report; measuring the beam measurement resources. The method further comprises determining, based on the measurement and the condition, whether to transmit the beam report; in response to determining to transmit the beam report, determining the beam report based on the measurement; and transmitting, via a resource from the resources for the PUSCH, the beam report. The resource for the PUSCH is a Type 1 configured grant PUSCH resource.

    Abstract: Methods and apparatuses for resource and reporting settings. A method performed by a user equipment (UE) includes receiving first information to enable transmission of an indicator indicating transmission of a beam report and transmitting, based on the first information, the indicator. The method further includes receiving second information related to one or more channel state information reference signal (CSI-RS) resources for the beam report; measuring, based on the second information, the one or more CSI-RS resources for the beam report; and transmitting the beam report.

    Abstract: Methods and apparatuses for transmission configuration indication (TCI) state indication and association for control and data channels. A method performed by a user equipment (UE) includes receiving first information for first and second groups of configured TCI states; receiving, in a downlink control information (DCI), a first indicated TCI state of a TCI codepoint; and receiving second information for a first control resource set (CORESET). The method further includes identifying, based on the first information, whether the first indicated TCI state is associated with the first or second group of configured TCI states; identifying, based on the second information, whether the first CORESET is associated with the first or second group of configured TCI states; and based on identifying that the first indicated TCI state and the first CORESET are associated with the same group of configured TCI states, receiving physical downlink control channel (PDCCH) candidates in the first CORESET according to the first indicated TCI state.

    Abstract: Methods and apparatuses for determination of a transmission configuration indication (TCI) state in a wireless communication system. A method for operating a user equipment (UE) includes receiving, in a first control resource set (CORESET), a downlink control information (DCI) indicating a first TCI state and receiving, in a radio resource control (RRC) signaling, (i) a first indicator configuring a value of coresetPoolIndex associated with the first CORESET and (ii) a second indicator. The method further includes identifying, based on the first indicator, an association between the value of coresetPoolIndex and the first TCI state; identifying, based on the second indicator, whether a simultaneous reception before an indicated TCI state is applicable is enabled; and determining, based on the identifications, one or more spatial filters for receiving a physical downlink shared channel (PDSCH) before the indicated TCI state is applicable, wherein the PDSCH is associated with the value of coresetPoolIndex.
