Description

Indication method and network equipment
Technical Field
The embodiment of the invention relates to the technical field of communication, in particular to an indicating method and network equipment.
Background
In the Fourth generation mobile communication technology (4G) system, a Single-carrier Frequency-Division Multiple Access (SC-FDMA) scheme is adopted in an uplink, and an Orthogonal Frequency Division Multiple Access (OFDMA) scheme is adopted in a downlink. In the standard of the Fifth generation communication technology New air interface (5G NR), the SC-FDMA mode or the OFDMA mode is used for the uplink, and the OFDMA mode is still used for the downlink. The above-described multiple access methods are all orthogonal multiple access. Although non-orthogonal transmission is studied in the Multi User Super Transmission (MUST) research project of Long term Evolution (LTE-pro) of 4G Professional, it is only directed to downlink transmission and all adopt a power domain non-orthogonal mode.
In the initial study of the third Generation Partnership project (3 rd Generation Partnership project,3 gpp) 5G NR, more novel non-orthogonal multiple access schemes were proposed, such as: sparse Code Multiple Access (SCMA), pattern Division Multiple Access (PDMA), interleaved Multiple Access (IDMA), non-orthogonal Code Access (NOCA), and the like. But limited by time schedule, in the first version of 3gpp 5G NR, a non-orthogonal multiple access approach is not introduced. But for further evolution of 5G NR, non-orthogonal multiple access is again proposed by the 3GPP standardization schedule.
Currently, a configured scheduling (scheduled) or scheduling-free (grant-free) uplink transmission mechanism has been introduced in the 3gpp 5G NR standard, the design assumption of the mechanism still uses the orthogonal Multiple Access technology, and in the standardization discussion of Non-orthogonal Multiple Access (NOMA), the combined use of the NOMA technology and grant-free transmission is considered, and no relevant discussion exists for the design of the NOMA signaling flow under grant-based.
