Abstract
Embodiments of the present disclosure provide a method for multiple input multiple output (MIMO) communications. For example, scheduling information is received at a terminal device from a network device, the scheduling information at least indicates physical resource blocks shared by a demodulation reference signal (DMRS) of the terminal device and a further DMRS of at least one further terminal device, and different sub-carriers allocated to the DMRS and the further DMRS in each of physical resource blocks, and the number of physical resource blocks is indivisible by a total number of the terminal device and the at least one further terminal device. The DMRS is generated, and a length of the DMRS is determined based on the number of physical resource blocks and the number of at least one further terminal device. The DMRS is transmitted to the network device on the sub-carriers allocated to the DMRS in the physical resource blocks. A corresponding method implemented at a network device such as a base station, and a terminal device and network device capable of implementing the above methods are also disclosed.
