摘要： A central controller (CC) [22] of a wireless Local area network (LAN) [20], in conjunction with an association operation with a mobile terminal [24] and upon receiving from the mobile terminal (MT) a first control signal [CS1] of a sequence of control signals involved in the association operation, pre-reserves a MAC resource for transmission of at least a further control signal in the sequence. The MAC resource for the further control signal is pre-reserved prior to information for the further control signal being stored in a transmission buffer [58] of the mobile terminal. In essence, judging from the nature of the first control signal, the central controller (CC) anticipates eventuality of the further control signal and pre-reserves the MAC resource for the further control signal. The central controller (CC) pre-reserves the MAC resource to avoid transmission of a separate message to request a MAC resource for the further control signal. The association operation for which the pre-reservation occurs can be, for example, an initial association scenario or a handover scenario in which the mobile terminal (MT) is handed over to the central controller (CC).
