Apparatus for and method of coordinating transmission and reception opportunities in a communications device incorporating multiple radios

A novel and useful apparatus for and method of coordinating the allocation of transmission and reception availability and / or unavailability periods for use in a communications device incorporating collocated multiple radios. The mechanism provide both centralized and distributed coordination to enable the coordination (e.g., to achieve coexistence) of multiple radio access communication devices (RACDs) collocated in a single device such as a mobile station. A distributed activity coordinator modifies the activity pattern of multiple RACDs. The activity pattern comprises a set of radio access specific modes of operation, (e.g., IEEE 802.16 Normal, Sleep, Scan or Idle modes, 3GPP GSM / EDGE operation mode (PTM, IDLE, Connected, DTM modes), etc.) and a compatible set of wake-up events, such as reception and transmission availability periods. To prevent interference and possible loss of data, a radio access is prevented from transmitting or receiving data packets while another radio access is transmitting or receiving. In the event two or more RATs desire to be active at the same time, the mechanism negotiates an availability pattern between the MS and a corresponding BS to achieve coordination between the RATs.
