Patent ID: 11337257

Abstract:
Methods and systems for random-access channel in 5G networks is described. In one aspect, a method for a contention based-random access (CB-RA) through a random access channel (RACH) is disclosed. A base station may configure a set of RA preambles for CB-RA in a configuration information. The base station may distribute the set of RA preambles between a defined first boundary and a second boundary using a continuous exponential distribution (ED) in the configuration information. The base station distributes the RA preambles to occur continuously and independently with a constant parametric rate between the first boundary and the second boundary. The at least one User Equipment (UE) receives the configuration information. The at least one UE selects and communicates at least one RA preamble from the set of RA preambles. The base station may receive the selected at least one RA preamble from the at least one UE.
