10 . The method of claim 1 , wherein the first request corresponds to a Pre-Notification (PN) or a request for UE-initiated beam report, and the second request corresponds to a Scheduling Request (SR).
11 . A User Equipment (UE), comprising:
a memory; and
a processor operatively coupled with the memory, wherein the processor is configured to execute a program code to:
be configured with a plurality of report configurations comprising a first report configuration associated with an event, a second report configuration not associated with any event, and a fourth report configuration associated with a second event, wherein the second event is based on a comparison between a quality of a current beam of a Serving Cell and a quality of a candidate beam of a candidate Cell, or the second event corresponds to a Layer 1/Layer 2 Triggered Mobility (LTM) event;
be configured with one or more trigger states associated with one or more report configuration, wherein the UE does not expect that any trigger state of the one or more trigger states is associated with the first report configuration associated with the event and the second report configuration not associated with any event;
triggering to transmit a first request for a first report associated with the first report configuration;
triggering to transmit a second request for a second report associated with the fourth report configuration;
transmitting the first request if a first Physical Uplink Control Channel (PUCCH) resource for the first request is overlapped with a second PUCCH resource for the second request in time domain, wherein the first request associated with the first report configuration has a higher priority than the second request associated with the fourth report configuration; and
transmitting the first report associated with the first report configuration.
12 . The UE of claim 11 , wherein the event corresponds to a comparison between a quality of a current beam of a Serving Cell and a quality of a candidate beam of the Serving Cell, or the event corresponds to a Multiple-Input Multiple-Output (MIMO) event or is associated with UE-initiated beam reporting.
13 . The UE of claim 11 , wherein the UE receives a third report configuration corresponding to an LTM-Channel State Information (CSI)-ReportConfig, and the UE does not expect that any trigger state of the one or more trigger states is associated with the first report configuration and the third report configuration or associated with the second report configuration and the third report configuration and/or for two overlapping Physical Uplink Shared Channels (PUSCHs), where one PUSCH is for transmitting a third report associated with the third report configuration and another PUSCH is for transmitting a fourth report associated with the second report configuration, and the UE prioritizes the third report over the fourth report.
