Abstract
Embodiments of the present disclosure relate to methods, devices and apparatuses for downlink retransmission for multi-TPR/panel transmission. In an embodiment of the present disclosure, a feedback for a downlink transmission is received from a terminal device, wherein in the downlink transmission, a data block is divided into at least a first data part and a second data part, the first data part is mapped to a first set of layers and a second data part is mapped to a second set of layers, and the first data part and the second data part are transmitted with different transmission configuration indication (TCI) states. A downlink retransmission of at least one of the first data part and the second data part is performed, in response to the feedback indicating a transmission failure, with the at least one of the first data part and the second data part being mapped to a different set of layers from one used in the downlink transmission. With embodiments of the present disclosure, it is possible to obtain more diversity gain, thereby achieving better retransmission performance for the multi-TPR/panel transmission.
