Abstract
This application relates to communication methods and apparatuses. In an example method, a first communication apparatus generates first indication information, and sends the first indication information to a second communication apparatus. The first indication information indicates M orbital angular momentum (OAM) modes jointly supported by the first communication apparatus and the second communication apparatus, where there is a correspondence between N OAM modes in the M OAM modes and a demodulation reference signal (DMRS) port.
Claims20
A method, comprising:
- generating, by a first communication apparatus, first indication information, wherein the first indication information indicates M orbital angular momentum (OAM) modes jointly supported by the first communication apparatus and a second communication apparatus, wherein there is a correspondence between N OAM modes in the M OAM modes and a demodulation reference signal (DMRS) port, wherein the DMRS port is an antenna port corresponding to a DMRS and a time-frequency resource corresponding to the DMRS port comprises a first part for transmitting the DMRS and a second part for transmitting information other than the DMRS, M and N are each an integer greater than 0, and M is greater than or equal to N;
- and
- sending, by the first communication apparatus, the first indication information to the second communication apparatus.
An apparatus, comprising at least one processor, and at least one memory coupled to the at least one processor, wherein the at least one memory stores programming instructions for execution by the at least one processor to cause the apparatus to perform operations comprising:
- generating first indication information, wherein the first indication information indicates M orbital angular momentum (OAM) modes jointly supported by the apparatus and a second communication apparatus, wherein there is a correspondence between N OAM modes in the M OAM modes and a demodulation reference signal (DMRS) port, wherein the DMRS port is an antenna port corresponding to a DMRS and a time-frequency resource corresponding to the DMRS port comprises a first part for transmitting the DMRS and a second part for transmitting information other than the DMRS, M and N are each an integer greater than 0, and M is greater than or equal to N;
- and
- sending the first indication information to the second communication apparatus.
An apparatus, comprising at least one processor, and at least one memory, wherein the at least one memory stores programming instructions for execution by the at least one processor to cause the apparatus to perform operations comprising:
- receiving first indication information from a first communication apparatus, wherein the first indication information indicates M orbital angular momentum (OAM) modes jointly supported by the first communication apparatus and the apparatus, wherein there is a correspondence between N OAM modes in the M OAM modes and a demodulation reference signal (DMRS) port, wherein the DMRS port is an antenna port corresponding to a DMRS and a time-frequency resource corresponding to the DMRS port comprises a first part for transmitting the DMRS and a second part for transmitting information other than the DMRS, M and N are each an integer greater than 0, and M is greater than or equal to N.
