Method and apparatus for controlling the distribution of multimedia broadcast services
First Claim
1. A method performed in a wireless transmit/receive unit (WTRU), the method comprising:
- receiving a multimedia broadcast/multicast service (MBMS) transmission from a first cell wherein the MBMS transmission includes one or more data segments of an MBMS;
storing received data segments from the MBMS transmission;
combining received data segments from the MBMS transmission and from at least one other MBMS transmission from a different cell that was transmitted at a different transmission time in response to received information,wherein the received information includes a MBMS combining schedule from a network, the combining of retransmitted segments is based on the MBMS combining schedule, and the received information indicates a transmission time difference between the first cell and the different cell time.

Abstract
A wireless multi-cell communication system and method of controlling the distribution of multimedia broadcast services (MBMS). 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.

11. A wireless transmit/received unit (WTRU) comprising:
-
circuitry configured to receive at least one block of multimedia broadcast/multicast service (MBMS) data over a secondary common control physical channel (S-CCPCH) from a first Node-B; the circuitry further configured to receive MBMS information indicating at least one time interval; wherein the circuitry is further configured to receive a first block of MBMS data over the S-CCPCH from the first Node-B and at the indicated time interval combine a second block of MBMS data received over a different S-CCPCH from a different Node-B with the first segment from the first Node-B, wherein the received MBMS information includes a MBMS combining schedule from a network, the combining of retransmitted segments is based on the MBMS combining schedule.

12. A wireless time division duplex (TDD) network comprising:
-
circuitry configured for a group of cells, to assign a first cell of the group to a first time slot (TS) for an MBMS transmission and to assign a second cell of the group to a second TS for the MBMS transmission; and wherein the first TS and the second TS are different TSs in a frame, wherein the MBMS transmission includes MBMS information including a MBMS combining schedule from a network, the combining of retransmitted segments is based on the MBMS combining schedule.
