Abstract

Apparatus and method for allocating communication resources in a data radio communication system, such as an MAIO (Mobile Allocation Index Offset) communication system, e.g., a communication system that provides for Enhanced Data for GSM Evolution (EDGE) data services. A multi-carrier radio resource control logic element includes an analyzer that analyzes communication resource requirements to carry out a communication service. A resource allocator allocates communication resources to be used by which to communicate the data. The communication resources are allocated across a plurality of radio carriers such that resources are allocated, during a particular time period, upon a single radio carrier of the plurality of radio carriers.

Claims (27)

1. An apparatus for a first communication station operable to communicate data in a communication scheme that provides for mobile allocation index offset, said apparatus comprising:

a radio element comprising a plurality of radio transceivers operable at a plurality of mobile allocations, said radio element transducing the data into electromagnetic form;

an analyzer that receives a characteristic of the data, that analyzes communication resource requirements so that the data can be transmitted in a series of time division multiple access (TDMA) frames, and that determines resources needed for dynamic resource allocation;

a resource allocator coupled to said analyzer to receive an indication of selection of a single mobile allocation index offset for each time period of operation within a TDMA frame to allocate resources upon said single mobile allocation index offset as a function of both resource availability and communication-station compatibility; and

a message generator to generate at least one control message to be provided to said radio element to cause individual ones of the radio transceivers to be operable during periods in which individual ones of the mobile allocation index offsets are allocated for communication.

2. The apparatus of claim 1 wherein the first communication station is operable to communicate with a second communication station, and wherein the indication of the selection of the single mobile allocation index offset for each time period operation is provided to the first communication station by the second communication station.

3. The apparatus of claim 1 , further comprising a radio protocol stack to which the data is applied; and

a baseband element, coupled to said radio protocol stack, to provide baseband processing, modulation, and channel coding for the data.

4. The apparatus of claim 3 , wherein the at least one control message is provided to the radio protocol stack and the baseband element to control their operation responsive to said resource allocation.

5. An apparatus for a mobile communication station operable to communicate data, said apparatus comprising:

a radio element comprising a plurality of radio transceivers operable at a plurality of mobile allocation index offsets and configured to receive an allocation message;

a detector configured to detect the allocation message and to extract values included in the allocation message, the allocation message including an indication of selection of a single mobile allocation index offset for each time period of operation within a TDMA frame; and

a controller adapted to receive an indication of detection made by said detector and, in response to said indication of detection, to cause individual ones of the radio transceivers of said radio element to be operable during time periods in which the individual ones of the mobile allocation index offsets are identified in the allocation message detected by said detector.

6. The apparatus of claim 5 further comprising a baseband element coupled to said radio element; and

a radio protocol stack coupled to said baseband element.

7. A method of data communication by a first communication station, said method comprising:

analyzing communication resource requirements based upon a characteristic of the data, to transmit data in a series of time division multiple access (TDMA) frames and to determine resources needed for dynamic resource allocation;

receiving an indication of selection of a mobile allocation index offset for a time period of operation, within a time division multiple access (TDMA) frame, from a second communication station;

allocating resources upon said single mobile allocation index offset as a function of both resource availability and communication station compatibility, the allocation of resources being made on a periodic basis; and

generating at least one control message to be provided to a radio element comprising a plurality of radio transceivers operable at a plurality of mobile allocation index offsets across which the resources are allocated to control operation of individual ones of the radio transceivers during time periods in which the individual ones of the mobile allocation index offsets are allocated for communication.

8. The method of claim 7 wherein allocations of the resources are further responsive to reaction times of the radio element.

9. The method of claim 7 wherein resources allocated are further responsive to non-communication measurement requirements of at least one of the first and second communication stations.

10. A method of data communication by a mobile communication station, comprising:

sending a characteristic of data and receiving an allocation message at a radio element that comprises a plurality of radio transceivers operable at a plurality of mobile allocation index offsets across which resources are allocated;

processing the allocation message at a baseband element and a radio protocol stack;

detecting the allocation message at a detector, the allocation message including an indication of selection of a single mobile allocation index offset for each time period of operation within a TDMA frame; and

receiving an indication of said detection of said allocation message and, in response to said indication of detection, controlling operation of the radio element for each time period within the TDMA frame to cause individual ones of said radio transceivers to be operable at least during time periods in which the individual ones of the mobile allocation index offsets are allocated for communication.
