Abstract: Embodiments of the present disclosure provide methods, devices and computer readable media for multi-TRP transmission. According to a method for communication, a terminal device receives downlink control information (DCI) from at least one of a plurality of network devices in communication with the terminal device, each of the plurality of network devices having a different demodulation reference signal (DMRS) group comprising a plurality of DMRS ports for transmitting DMRSs. The terminal device determines, from the DCI, respective transmission configuration indication (TCI) states for DMRS groups of the plurality of network devices and DMRS ports for receiving DMRSs transmitted by the plurality of network devices. The terminal device receives the DMRSs from the plurality of network devices on the DMRS ports based on the TCI states. The embodiments of the present disclosure provide solution of multi-TRP communication with reduced overhead.
