Samsung patents signal shapes to boost wireless data efficiency
Samsung describes a method where phones and cell towers agree on using specific, irregular signal patterns called rectangular non-uniform modulation constellations. The device tells the tower it can handle these patterns, and the tower sends instructions on how to pack data bits into them for transmission. The system also includes a way to switch back to standard patterns if the connection becomes unstable.
In the filing’s own words
UE capability information indicating support for rectangular non-uniform modulation constellations (NUMCs) and rectangular NUMC configuration information are exchanged by a UE and BS. Based on an MCS indication corresponding to a rectangular NUMC, bits to be transmitted are mapped to the indicated NUMC and corresponding modulation symbols are transmitted. Configuration information may include indicator(s) enabling/disabling MCS index mapping to rectangular NUMCs, rectangular NUMC identifiers, or rectangular NUMC bit-to-symbol mappings, either as mapping tables or coefficient sets. UE assistance information may include UE trajectory, UE sensor information, or an MCS index for a recommended rectangular NUMC. A fallback indication or command for switching to conventional constellations may be sent from the UE to the BS or from the BS to the UE.
What exactly they claim (claim 1)
1. A user equipment (UE) comprising: a transceiver configured to send, to a base station, capability information including an indication of support for rectangular non-uniform modulation constellations, receive, from the base station, rectangular non-uniform modulation constellation configuration information, and receive, from the base station, a modulation and coding scheme (MCS) indication; and at least one processing device coupled to the transceiver, the at least one processing device configured to map a plurality of bits to be transmitted to a rectangular non-uniform modulation constellation based on the MCS indication, wherein the transceiver is configured to transmit modulation symbols corresponding to the rectangular non-uniform modulation constellation to which the plurality of bits were mapped.
