A method performed by a wireless communication device (1112, 2600) in a cellular communications system, the method comprising: • receiving, from a network node, a Medium Access Control, MAC, Control Element, CE, for Transmission Configuration Indication, TCI, state activation or deactivation, the MAC CE comprising: o information that: ▪ activates one or more TCI states; ▪ defines a codepoint to TCI state mapping, wherein the codepoint to TCI state mapping maps each of a plurality of codepoints for a Downlink Control information, DCI, transmission configuration indication field to at most X of the one or more TCI states activated by the MAC CE, where X is an integer greater than or equal to 1; and o a control resource set, CORESET, pool identity, ID, that indicates that the one or more TCI states activated by the MAC CE and the codepoint to TCI state mapping defined by the information comprised in the MAC CE are to be applied to a physical downlink control channel, PDCCH, that is carried within any CORESET in a CORESET pool indicated by the CORESET pool ID; • receiving a PDCCH carried within a CORESET in the CORESET pool indicated by the CORESET pool ID, the PDCCH comprising a DCI in which the DCI transmission configuration field is set to a particular codepoint from among the plurality of codepoints for the DCI transmission configuration field; and • determining a TCI state from among the one or more TCI states activated by the MAC CE used for a PDSCH scheduled by the DCI based on the information comprised in the DCI. • receiving, from a network node, a Medium Access Control, MAC, Control Element, CE, for Transmission Configuration Indication, TCI, state activation or deactivation, the MAC CE comprising: o information that: ▪ activates one or more TCI states; ▪ defines a codepoint to TCI state mapping, wherein the codepoint to TCI state mapping maps each of a plurality of codepoints for a Downlink Control information, DCI, transmission configuration indication field to at most X of the one or more TCI states activated by the MAC CE, where X is an integer greater than or equal to 1; and o a control resource set, CORESET, pool identity, ID, that indicates that the one or more TCI states activated by the MAC CE and the codepoint to TCI state mapping defined by the information comprised in the MAC CE are to be applied to a physical downlink control channel, PDCCH, that is carried within any CORESET in a CORESET pool indicated by the CORESET pool ID; o information that: ▪ activates one or more TCI states; ▪ defines a codepoint to TCI state mapping, wherein the codepoint to TCI state mapping maps each of a plurality of codepoints for a Downlink Control information, DCI, transmission configuration indication field to at most X of the one or more TCI states activated by the MAC CE, where X is an integer greater than or equal to 1; and ▪ activates one or more TCI states; ▪ defines a codepoint to TCI state mapping, wherein the codepoint to TCI state mapping maps each of a plurality of codepoints for a Downlink Control information, DCI, transmission configuration indication field to at most X of the one or more TCI states activated by the MAC CE, where X is an integer greater than or equal to 1; and o a control resource set, CORESET, pool identity, ID, that indicates that the one or more TCI states activated by the MAC CE and the codepoint to TCI state mapping defined by the information comprised in the MAC CE are to be applied to a physical downlink control channel, PDCCH, that is carried within any CORESET in a CORESET pool indicated by the CORESET pool ID; • receiving a PDCCH carried within a CORESET in the CORESET pool indicated by the CORESET pool ID, the PDCCH comprising a DCI in which the DCI transmission configuration field is set to a particular codepoint from among the plurality of codepoints for the DCI transmission configuration field; and • determining a TCI state from among the one or more TCI states activated by the MAC CE used for a PDSCH scheduled by the DCI based on the information comprised in the DCI.
