Methods and procedures for simultaneous transmissions and reception

A wireless transmit receive unit (WTRU), the WTRU comprising:

• a transceiver operatively connected to a processor, the transceiver and processor configured to receive radio resource control (RRC) configuration information,
• wherein the RRC configuration information indicates a first number of channel state information-reference signal (CSI-RS) resources of a first set and a second number of CSI-RS resources of a second set,
• wherein the first set has a different quantity of resources than the second set,
• wherein a first CSI-RS resource from the first number of CSI-RS resources and a second CSI-RS resource from the second number of CSI-RS resources form a pair of CSI-RS resources that are configured within a same slot,
• wherein the RRC configuration information indicates a reporting constraint of a plurality of reporting constraints;
• the processor configured to the transceiver and processor configured to determine beam related information including a first CSI resource indicator (CRI), a second CRI, and a third CRI,
• wherein the first CRI corresponds to the first and second CSI-RS resources of the pair of CSI-RS resources, the second CRI corresponds to the first CSI-RS resource from the first number of CSI-RS resources, and the third CRI corresponds to the second CSI-RS resource from the second number of CSI-RS resources;
• and
• the transceiver and processor configured to send CSI reporting information including a selection of the beam related information based on the reporting constraint of a plurality of reporting constraints.
