Abstract
An MS, for a GSM/EDGE network, arranged to, as a first alternative, use every 13th TDMA frame with an odd number as an idle frame which is used for neighboring cell measurements and every 13th TDMA frame with an even number as a PTCCH, a Packet Timing Control Channel. The MS is arranged to, as a second alternative, use every 13th TDMA frame with an odd number as a PTCCH and every 13th TDMA frame with an even number for neighboring cell measurements. The MS is arranged to transmit information to the network that the MS supports the use of the second alternative, and to receive information from the network about which of these two alternatives that the MS should use.
