A method and means for frequency hopping in a radio communication system

TLDR: In this article, the interference values of the uplink and the downlink respectively are stored in an interference list (IL) for each of the connections, and the weight values are analyzed in an allocation circuit (W/Hup), which allocates channels to individual hop sequence lists (HL1up-HL3up).

Abstract: Frequency hopping and hops between time-divided channels (K1, K2, ..) is carried out in a mobile telecommunications system. Hop sequences are established for individual connections for hops between the channels, thereby improving utilization of the channels in the system. Interference (I) is measured on the channels (K1, K2, ..) for individual connections between a base station (BS1) and a plurality of mobile stations. The connections are bidirectional, having an uplink and a downlink. The measured interference values of the uplink and the downlink respectively are stored in an interference list (IL) for each of the connections. The drawing shows three interference lists (IL1up-IL3up) in the uplink, including channel numbers (K1, K2, ..) and the measured interference values (I1, I2, ..). The interference values are converted to weight values (0.1; 0.3; ..) in a conversion circuit (I/Wup), and the weight values are then stored in weight lists (WL1up-WL3up). The weight values are analyzed in an allocation circuit (W/Hup), which allocates channels to individual hop sequence lists (HL1up-HL3up). Each connection is allocated a respective hop sequence list. The hop sequence lists are sent to respective mobile stations, thereby providing the mobile stations with information as to which hop sequence list shall be used.
