Abstract: An example method includes receiving a configuration from the wireless communication node. The configuration indicates at least one of one or more numbers of port groups or one or more levels of coherence. The example method further includes determining a precoder for a transmission according to the configuration. The example method further includes performing the transmission using the precoder. In some embodiments, a total number of ports across the port groups is eight.

Abstract: Methods, apparatus, and systems that enable reliable uplink timing alignment with multiple transmission points are disclosed. In one example aspect, a method for wireless communication includes receiving, by a terminal device, a message comprising a timing advance command and determining, by the terminal device, at least one transmission parameter based on the message. The at least one transmission parameter is associated with the timing advance command. The method also includes applying, by the terminal device, the timing advance command to a transmission associated with the at least one transmission parameter.
