Patent ID: 7072327

Claim:
In a telecommunications system in which a plurality of User Equipments (UEs) communicate with a common station via communication signals having a system frame format with at least one commonly used time slot (CUTS) per frame which is available for common use by the UEs for transmitting code identified signals for a specific uplink channel, where the UEs select a code identifier from a plurality of identifiers and where a UE transmission with a selected code identifier in a selected CUTS will fail if another UE transmits with the same code identifier in the same CUTS or if the UE transmission lacks sufficient power, a communication method comprising: determining the number of successful and failed UE transmissions in CUTSs per frame that are received by the common station from the plurality of UEs; adjusting one or more communication parameters, including a dynamic persistence parameter (DP) or a power control parameter (R), in response to said determination; and broadcasting by the common station the adjusted one or more communication parameters.
