Abstract

A system and method for configuring the system for configuring a wireless multi-cell communication to provide multimedia broadcast services (MBMS) to a plurality of wireless transmit/receive units (WTRUs). The cells of the communication system are organized into a plurality of sets of one or more cells. Resource units are assigned to each set of cells in the communication system. The assigned resource units are allocated in each cell of the communication system for MBMS transmission. The WTRUs receive information indicating how to access the resource units allocated for MBMS transmission. The WTRUs receive the MBMS from one or more of the cells of the communication system.

Claims

1. A method of providing multimedia broadcast services (MBMS), the method comprising:

organizing a plurality of wireless communication cells into a plurality of cell sets, each cell set having at least one cell;

determining whether or not to use multi-frame allocations; and

on a condition that the use of multi-frame allocations is determined, establishing a repetition period for all cells and a subset of frames to be used for MBMS transmission for each repetition period for each set of cells.

2. The method of claim 1 further comprising:

allocating assigned resource units in each cell for MBMS transmission.

3. The method of claim 2 further comprising:

providing information indicating how to access the resource units allocated for MBMS transmission.

4. The method of claim 3 further comprising:

determining whether current MBMS requirements are fulfilled with respect to previously established MBMS requirements.

5. The method of claim 1 wherein combinations of time slots are reused.

6. The method of claim 5 wherein the reusing of combinations of time slots is based on time slot repetition periods.

7. The method of claim 6 wherein a time-domain reuse factor of 3 is used.

8. A wireless communication apparatus configured to provide multimedia broadcast services (MBMS), the wireless communication apparatus configured to:

organize a plurality of wireless communication cells into a plurality of cell sets, each cell having at least one cell;

determine whether or not to use multi-frame allocations; and

on a condition that the use of multi-frame allocations is determined, establish a repetition period for all cells and a subset of frames to be used for MBMS transmission for each repetition period for each set of cells.

9. The apparatus of claim 8 further configured to:

allocate assigned resource units in each cell for MBMS transmission.

10. The apparatus of claim 9 further configured to:

provide information indicating how to access the resource units allocated for MBMS transmission.

11. The apparatus of claim 10 further configured to:

determine whether current MBMS requirements are fulfilled with respect to previously established MBMS requirements.

12. The apparatus of claim 8 wherein combinations of time slots are reused.

13. The apparatus of claim 12 wherein the reusing of combinations of time slots is based on time slot repetition periods.

14. The apparatus of claim 13 wherein a time-domain reuse factor of 3 is used.
