초록 ▼

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.

대표청구항 ▼

1. A method, performed by a wireless transmit/receive unit (WTRU), the method comprising: receiving a first multimedia broadcast/multicast service (MBMS) transmission from a first cell;storing the first MBMS transmission;receiving a second MBMS transmission from a second cell, wherein the second MBMS transmission is received at a different transmission time than the first MBMS transmission; andcombining the first MBMS transmission and the second MBMS transmission based on received information from a network, wherein the received information includes an MBMS combining schedule and a transmission time difference. 2. The method of claim 1 wherein the first MBMS transmission is received over a secondary common control physical channel (S-CCPCH). 3. The method of claim 1 wherein the second MBMS transmission is received over a secondary common control physical channel (S-CCPCH). 4. A wireless transmit/receive unit (WTRU) comprising: a receiver configured to receive a first multimedia broadcast/multicast service (MBMS) transmission from a first cell;memory configured to store the first MBMS transmission;the receiver further configured to receive a second MBMS transmission from a second cell, wherein the second MBMS transmission is received at a different transmission time than the first MBMS transmission; anda processor configured to combine the first MBMS transmission and the second MBMS transmission based on received information from a network, wherein the received information includes an MBMS combining schedule and a transmission time difference. 5. The WTRU of claim 4 wherein the first MBMS transmission is received over a secondary common control physical channel (S-CCPCH). 6. The WTRU of claim 4 wherein the second MBMS transmission is received over a secondary common control physical channel (S-CCPCH). 7. A wireless transmit/receive unit (WTRU) comprising: circuitry configured to receive a first multimedia broadcast/multicast service (MBMS) transmission over a first secondary common control physical channel (S-CCPCH) from a first Node-B;the circuitry further configured to receive a second MBMS transmission over a second S-CCPCH from a second Node-B;the circuitry further configured to receive MBMS information, wherein the MBMS information includes an MBMS combining schedule and a transmission time difference; andthe circuitry is further configured to combine the first MBMS transmission and the second MBMS transmission, wherein the combining is based on the MBMS combining schedule and the transmission time difference. 8. A method, performed by a wireless transmit/receive unit (WTRU), the method comprising: receiving a first multimedia broadcast/multicast service (MBMS) transmission over a first secondary common control physical channel (S-CCPCH) from a first Node-B;receiving a second MBMS transmission over a second S-CCPCH from a second Node-B;receiving MBMS information, wherein the MBMS information includes an MBMS combining schedule and a transmission time difference; andcombining the first MBMS transmission and the second MBMS transmission, wherein the combining is based on the MBMS combining schedule and the transmission time difference.
