Abstract:
A TDMA/TDD media access control frame structure encoded in a computer-readable medium, said control frame structure comprising:a broadcast message having a common dynamically updated physical layer parameter indicator for a plurality of uplink channels, said common dynamically updated physical layer parameter indicator for indicating a decision relating to a chosen transmission/reception mode for performing radio cell adaptation on said associated uplink channels; wherein an indicator change forces a change of transmission/reception mode to said chosen transmission/reception mode for all of said plurality of uplink channels; an announcement and assignment message having an individual dynamically updated physical layer parameter indicator for a particular downlink channel, said individual dynamically updated physical layer parameter indicator for indicating a decision relating to a chosen transmission/reception mode for performing individual link adaptation for a particular mobile station associated with said particular downlink channel; and wherein said broadcast message indicates a proper physical layer parameter that is to be used by a receiver to decode said individual dynamically updated physical layer parameter indicator included in the announcement and assignment message.
