A Radio Resource-Efficient Paging Method in High Frequency 5G Networks

Conventional paging methods are associated with increased radio resource overhead when deployed in high frequency networks. This is due to the beam sweeping involved, which, particularly for large number of beams, renders conventional paging inefficient. This work provides an assessment in terms of radio resource usage efficiency of an alternative paging scheme, which we recently proposed for 5G. Such assessment involves analytical expressions for the expected number of user equipment conducting uplink access, followed by a study of the resulting trade-off between uplink and downlink consumed resources.
