Abstract:
1. A method of assigning transmission channels in a telecommunications network having a plurality of base stations and a plurality of mobile stations, the transmission channels being provided for transmitting signals between the plurality of base stations and the plurality of mobile stations, the method comprising: in an uncoordinated operation of the base stations for establishing a connection between one of the base stations and one of the mobile stations, assigning an uplink and a downlink transmission channel for the transmission of signals between the one of the base stations and the one of the mobile stations; wherein said one of the base stations and said one of the mobile stations each perform a channel measurement on all possible transmission channels to determine whether such transmission channels are below a pre-selected value for connection quality and said uplink and downlink transmission channels are assigned based on said measurement, and thereafter said one of the base stations and said one of the mobile stations repeatedly re-measure all of the possible transmission channels not previously used to determine whether such transmission channels are below a pre-selected value for connection quality; wherein the channel measurement on all possible transmission channels is performed prior to the assigning of the uplink channel and the downlink channel, and wherein the mobile station performs the channel measurement for channel transmissions in the downlink direction and the base station performs the channel measurement for channel transmissions in the uplink direction with independent assignment of the uplink channel and the downlink channel.
