Service data is transferred in a wireless communication system. A first service identification is transmitted for reception by a group of users of a cell in the system. The group of users does not include all of the users of the cell. Each of the group of users receives the service identification. Each of the group of users monitors for a second service identification being transmitted over a high speed downlink shared channel (HS-DSCH). The service data is transmitted over the HS-DSCH with the second service identification. Each of the group of users detects the second service identification and receives the service data of the HS-DSCH.

1. A method for use in wireless communications, the method comprising: selectively transmitting on a control channel, on a transmission time interval (TTI) basis, point to multipoint (PtM) service control information or point to point (PtP) control information;wherein on a condition that PtM service
1. A method for use in wireless communications, the method comprising: selectively transmitting on a control channel, on a transmission time interval (TTI) basis, point to multipoint (PtM) service control information or point to point (PtP) control information;wherein on a condition that PtM service control information is transmitted, the PtM service control information is transmitted with a PtM service identification to a group of PtM users, the PtM service identification indicating that the PtM users are to receive PtM data in a first TTI, and the PtM data is transmitted in the first TTI to the group of PtM users;wherein on a condition that PtP control information is transmitted, the PtP control information is transmitted with a user equipment identification (UE ID) of a single user, and PtP data is transmitted in a second TTI to the single user on a shared channel that time shares resources with the PtM data; andwherein the PtM service control information includes a modulation and coding scheme (MCS) of the PtM data. 2. The method of claim 1, wherein the UE ID is encoded in a cyclic redundancy check. 3. The method of claim 1, wherein the PtM data comprises multimedia data. 4. A base station for use in wireless communications, the base station comprising: a transmitter coupled to an antenna and comprising circuitry configured to selectively transmit on a control channel, on a transmission time interval (TTI) basis, point to multipoint (PtM) service control information or point to point (PtP) control information,wherein on a condition that PtM service control information is transmitted, the circuitry is further configured to transmit the PtM service control information is transmitted with a PtM service identification to a group of PtM users, the PtM service identification indicating that the PtM users are to receive PtM data in a first TTI, and the circuitry is further configured to transmit the PtM data in the first TTI to the group of PtM users;wherein on a condition that PtP control information is transmitted, the circuitry is further configured to transmit the PtP control information with a user equipment identification (UE ID) of a single user, and to transmit PtP data in a second TTI to the single user on a shared channel that time shares resources with the PtM data; andwherein the PtM service control information includes a modulation and coding scheme (MCS) of the PtM data. 5. The base station of claim 4, wherein the UE ID is encoded in a cyclic redundancy check (CRC). 6. The base station of claim 4, wherein the PtM data comprises multimedia data. 7. A wireless transmit/receive unit (WTRU) for use in wireless communications, the WTRU comprising: a receiver coupled to an antenna and comprising circuitry configured to receive a signal including control information on a control channel, wherein the control information comprises point-to-multipoint (PtM) service control information or point to point (PtP) control information;wherein on a condition that the signal includes a PtM service identification of a group of PtM users, the circuitry is further configured to receive PtM data in a first TTI; andwherein on a condition that the signal includes a user equipment identification (UE ID) of the WTRU, the circuitry is further configured to receive PtP data in a second TTI on a shared channel that time shares resources with the PtM data; andwherein the PtM service control information includes a modulation and coding scheme (MCS) of the PtM data; andwherein the PtP control information includes a MCS of the PtP data. 8. The WTRU of claim 7, wherein the UE ID is encoded in a cyclic redundancy check (CRC). 9. The WTRU of claim 7, wherein the PtM data comprises multimedia data. 10. A method for use in a wireless transmit/receive unit (WTRU), the method comprising: receiving, by a receiver coupled to an antenna, a signal including control information on a control channel, wherein the control information comprises point-to-multipoint (PtM) service control information or point to point (PtP) control information;wherein on a condition that the signal includes a PtM service identification of a group of PtM users, the receiver is configured to receive PtM data in a first TTI;wherein on a condition that the signal includes a user equipment identification (UE ID) of the WTRU, the receiver is configured to receive PtP data in a second TTI on a shared channel that time shares resources with the PtM data; andwherein the PtM service control information includes a modulation and coding scheme (MCS) of the PtM data; andwherein the PtP control information includes a MCS of the PtP data. 11. The method of claim 10, wherein the UE ID is encoded in a cyclic redundancy check (CRC). 12. The method of claim 10, wherein the PtM data comprises multimedia data.
