Patent ID: 8462762

Claim:
A radio communication system, comprising: a coordinator unit; at least one communications terminal, in which access to a radio resource is structured in accordance with time-division multiplexing; and an accessory unit; wherein the radio resource is divided into determinate time frames and the coordinator unit allocates to the at least one communications terminal at least one useful data transmission time slot, a temporal position of each at least one useful data transmission time slot being determined in individual sequential time frames with respect to a beginning of a particular time frame; wherein the individual sequential time frames are structured such that each time frame contains a synchronization time slot, the at least one useful data transmission time slot of equal length and an additional dynamic time slot; the additional dynamic time slot being usable by at least one of a specific one of the at least one communications terminal to which the at least one useful data transmission time slot has not been allocated and the accessory unit, and the coordinator unit synchronizing with a synchronization message in the synchronization time slot that preceded the additional dynamic time slot before the at least one communications terminal uses the additional dynamic time slot; and wherein the accessory unit is configured to indicate to the coordinator unit in an accessory unit parameterization message that said accessory unit wants to parameterize one of the at least one communications terminal in an ad hoc parameterization operating mode and the coordinator unit is configured to in the synchronization message force said one of the at least one communications terminal to switch into the ad hoc parameterization operating mode.
