POINT TO MULTI-POINT SERVICES USING HIGH SPEED SHARED CHANNELS IN WIRELESS COMMUNICATION SYSTEMS

摘要

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, point to multipoint (PtM) service control information or point to point (PtP) control information, on a transmission time interval (TTI) basis; 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 PtM TTI, and the PtM data is transmitted in the PtM TTI to the group of PtM users; and 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 PtP TTI to the single user on a shared channel that time shares resources with the PtM data.
