Abstract
Embodiments of the present disclosure relate to methods and devices for data transmission. In example embodiments, a method implemented in a network device is provided. According to the method, a target RS port group is determined from a plurality of RS ports for transmitting a RS. The RS ports are associated with at least one network device. Then, a configuration of the target RS port group is transmitted to the terminal device.
Claims21
A method performed by a terminal device, comprising:
- receiving information via a plurality of Physical Downlink Control Channels (PDCCHs) for scheduling a plurality of Physical Downlink Shared Channels (PDSCHs) from a plurality of Transmission Reception Points (TRPs);
- receiving information via the plurality of PDSCHs from the plurality of TRPs;
- and
- receiving a plurality of Demodulation Reference Signals (DMRSs) for the plurality of PDSCHs from the plurality of TRPs,
- wherein configurations of the plurality of DMRSs from the plurality of TRPs are same,
- wherein one of the configurations of the plurality of DMRSs is a DMRS configuration with respect to at least one of a DMRS configuration type, a first number of symbols for a front-loaded DMRS, and a second number of symbols for an additional DMRS.
