Abstract:
A method, wireless device and network node are disclosed. According to one embodiment, a network node is configured to transmit within a medium access control, MAC, control element, CE, message, an indication of a plurality KJ of Transmission Configuration Indication, TCI, states that are mapped to a single codepoint, j, in a downlink control information, DCI, Transmission Configuration Indication, TCI, field, Kj and j being integers, and transmit within the MAC CE message, the number Kj of TCI states being mapped to the codepoint j. In another embodiment, a wireless device is configured to receive within a MAC CE message from the network node, an indication of a plurality Kj of TCI states that are mapped to a single codepoint, j, in a DCI TCI field, and receive within the MAC CE message, the number Kj of TCI states mapped to the codepoint j.
