Abstract: A method for bandwidth allocation is to be implemented by a base station (BS) that communicates with a plurality of reconfigurable intelligent surfaces (RISs). The method comprising steps of: receiving a plurality of join messages respectively from a plurality of user equipments (UEs) via the RISs, the join messages being transmitted simultaneously by the UEs in a contention area according to a map message; and according to the join messages, grouping the UEs into at least one group by allocating a frequency band within the contention area to each of the at least one group, wherein those of the UEs in the same group share the same frequency band.
