Beam failure detection and/or beam failure recovery procedures

An apparatus, comprising:

• at least one processor;
• and
• at least one memory comprising computer program code,
• the at least one memory and computer program code being configured to, with the at least one processor, cause the apparatus at least to:
• receive, from a user equipment, a beam report to indicate an association between at least two downlink reference signals and at least two antenna panels at the user equipment and activating transmission configuration indicator (TCI) states for at least one control resource set (CORESET) or physical downlink shared channel (PDSCH) that causes the user equipment to receive physical downlink control channel (PDCCH) or physical downlink shared channel (PDSCH) with more than one active antenna panel, or to configure transmission configuration indicator (TCI) states for at least one control resource set (CORESET) or physical downlink shared channel (PDSCH) to indicate the downlink reference signals that can be used for downlink reception at the user equipment and receive, from the user equipment, a beam report comprising an indication of a selection of at least two downlink reference signals that will be used for downlink reception at the user equipment simultaneously through the at least two antenna panels;
• and
• configure the user equipment with at least two sets of beam failure detection resources for one or more of the at least two antenna panels;
• and
• transmit an indication, via a medium access control (MAC) control element (CE) or physical downlink shared channel (PDSCH) or physical downlink control channel (PDCCH), that the user equipment can perform partial beam failure detection, or wherein the transmitting comprises transmitting a configuration with radio resource control (RRC) layer parameters indicating that the user equipment can perform partial beam failure detection.
