Abstract
Embodiments of the present disclosure relate to methods, devices and computer readable media for multi-TRP transmission. The method comprises determining at least one transmission configuration indication (TCI) state to be configured to a terminal device, the at least one TCI state indicating a plurality of reference signal (RS) sets and quasi co-location relationship between the plurality of RS sets and respective groups of DMRS ports. The method further comprises determining DMRS ports for transmitting DMRSs to the terminal device via the plurality of TRPs and associations between the plurality of RS sets and the DMRS ports. In addition, the method further comprises configuring the at least one TCI state, the DMRS ports, and the associations between the plurality of RS sets and the DMRS ports to the terminal device. In this way, multi-TRP transmission can be supported without introducing additional indication overhead.
