Abstract
This application relates to a communication method and apparatus. In the method, when first information indicates an SDM scheme or an SFN scheme, second information may include two PTRS-DMRS fields, and one of the PTRS-DMRS fields is 0 bits. In this way, bit overheads of DCI can be reduced. In addition, a first field in the second information clearly indicates a specific transmission scheme to be used by a terminal device.
Claims18
A communication method, comprising:
- receiving first information, wherein the first information indicates a first transmission scheme, and the first transmission scheme comprises a spatial domain multiplexing (SDM) scheme or a single frequency network (SFN) scheme;
- and
- receiving second information, wherein the second information comprises a first field, the first field indicates to a terminal device to use the first transmission scheme or a second transmission scheme, and the second transmission scheme is a single transmission reception point (sTRP) scheme, wherein
- the second information further comprises a second field and a third field, the second field is a phase tracking reference signal (PTRS)-demodulation reference signal (DMRS) field, the third field is a second PTRS-DMRS field, and the third field is 0 bits.
