Abstract

A wireless multi-cell communication system and method of controlling the distribution of multimedia broadcast services (MBMS) are disclosed. The system includes at least one network, e.g., a Universal Terrestrial Radio Access Network (UTRAN), which distributes the MBMS to one or more wireless receive/transmit units (WTRUs). In one embodiment, the MBMS are activated and deactivated based on whether periodic cell updates are provided for a particular cell. In another embodiment, MBMS transmission is terminated when receipt of the MBMS are confirmed. In yet another embodiment, the MBMS are segmented to reduce the resources used by the network and/or the WTRUs during MBMS distribution.

Claims

1. A method comprising:

a network node providing each of a plurality of cells data associated with a multimedia broadcast multicast service (MBMS);

each of the plurality of cells transmitting segments of the MBMS data such that a wireless transmit/receive unit (WTRU) receives segments from at least two of the plurality of cells;

wherein the plurality of the cells transmit the segments in a coordinated time interval pattern;

wherein each time interval in the pattern includes at least one slot.

2. The method of claim 1, wherein the coordinated time interval pattern repeats.

3. A method comprising:

receiving, by a wireless/transmit receive unit (WTRU), segments of multimedia broadcast multicast service (MBMS) data from at least two of a plurality of cells;

recovering data of the MBMS from the received segments;

wherein the received segments are received from the plurality in cells in a coordinated time interval pattern;

wherein each time interval in the pattern includes at least one time slot.

4. The method of claim 3, wherein the coordinated time interval pattern repeats.

5. A wireless transmit/receive unit (WTRU) comprising:

a device configured to receive segments of multimedia broadcast multicast service (MBMS) data from at least two of a plurality of cells;

wherein the device is further configured to recover data of the MBMS from the received segments;

wherein the received segments are received from the plurality in cells in a coordinated time interval pattern;

wherein each time interval in the pattern includes at least one time slot.

6. The WTRU of claim 5, wherein the coordinated time interval pattern repeats.
