Claim of US Patent No. 10,798,734

1. A method for transmitting a Physical Random Access Channel (PRACH) preamble in a wireless communication network, the method comprising:dividing, by a wireless device, a Narrowband Physical Random Access Channel (NPRACH) preamble into a plurality of symbol groups;
selecting, by the wireless device, at least one first symbol group from the plurality of symbol groups and at least one second symbol group from the plurality of symbol groups;
adding, by the wireless device, a first Guard Period (GP) between the at least one first symbol group and the at least one second symbol group, wherein the first GP is added at the end of the at least one first symbol group;
adding, by the wireless device, a second GP at an end of the at least one second symbol group; and
transmitting, by the wireless device, the at least one first symbol group along with the first GP in first available consecutive Up-Link (UL) sub-frames; and
transmitting, by the wireless device, the at least one second symbol group along with the second GP in subsequent consecutive UL sub-frames after transmission of the at least one first symbol group along with the first GP, wherein the first available consecutive UL sub-frames and the subsequent consecutive UL sub-frames are reserved for UL transmission in at least one frame duration.
