Embodiments of the present disclosure are related, in general to communication, but exclusively relate to communication in a time division duplex (TDD) network. A user equipment (UE) transmits a Physical Random-Access Channel (PRACH) to an enhanced node base (eNodeB) even in low coverage scenario. The PRACH had to be transmitted in any available uplink sub-frame. The Narrow band - Internet of things (NB-IoT) N-PRACH channel for TDD (time division duplex) communication system with 5KHz sub carrier spacing is used for transmission in in-band, guard band and standalone band deployments. In available duration of 1 msec for uplink, multiple NPRACH symbols is be transmitted.
