Abstract
Systems, methods, and devices are disclosed for determining a beam modulation mode and/or a carrier modulation mode. A beamformed reference signal may be transmitted to a wireless transmit/receive unit (WTRU). A beam measurement report may be received from the WTRU. The beam measurement report may include a beam modulation mode recommendation and/or a carrier modulation mode recommendation. A beam modulation mode and/or a carrier modulation mode may be determined based on a mode recommendation. A beam modulation mode and/or a carrier modulation mode may indicate a manner of transmitting same information on multiple beams.
Claims15
A wireless transmit/receive unit (WTRU) comprising:
- a processor configured to:
- receive a first beamformed reference signal from a first transmission and reception point (TRP) and a second beamformed reference signal from a second TRP;
- perform a first beam measurement on the first beamformed reference signal and a second beam measurement on the second beamformed reference signal;
- send a beam measurement report based on the first and second beam measurements, wherein the beam measurement report comprises a recommendation to utilize a multi beam modulation (MBM) mode, and wherein the MBM mode indicates a manner to map a same set of information bits to multiple constellation symbols and transmit the same set of information bits mapped to multiple constellation symbols over associated multiple beams;
- receive an indication from a TRP that indicates the MBM mode;
- and
- receive a first data transmission from the first TRP that utilizes a first modulation and a second data transmission from the second TRP that utilizes a second modulation, wherein the first modulation is different than the second modulation.
