Claim of US Patent No. 10,397,947

1. A method for adaptive waveform selection for signal transmission in a wireless communication system, the method comprising:analyzing, by a wireless device of the wireless communication system, at least one attribute of a wireless communication associated with a random access procedure, the at least one attribute including at least one of: system information present in a broadcast downlink message, information in a random access response message, a physical random access channel (PRACH) sequence used for initial access, and a measurement made by the wireless device; and
determining a waveform to use for at least one uplink random access message transmission associated with the random access procedure, wherein the determining is based on the analyzed at least one attribute, wherein the waveform is one from a plurality of waveforms for uplink signal transmissions, wherein the at least one uplink random access message includes a third message to be transmitted after receiving a random access response message, wherein the determining the waveform to use for the at least one uplink random access message transmission includes determining a waveform to use for the third message, and wherein the plurality of waveforms comprise a single-carrier frequency division multiplexing (SC-FDM) waveform design and an orthogonal frequency division multiplexing (OFDM) waveform design.
