Abstract

Service data is transferred in a wireless communication system. A first service identification is synchronously 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 downlink shared channel. The service data is transmitted over the downlink shared channel with the second service identification. Each of the group of users detects the second service identification and receives the service data of the downlink shared channel.

Claims

1. A user equipment, comprising:

circuitry configured to monitor at least one downlink control channel for information derived from an identification for a group of user equipments,

wherein the circuitry is further configured in response to receiving the information derived from the group identification to receive data over a downlink shared channel;

wherein the circuitry is further configured to monitor at least one downlink control channel for information derived from an identification for a single user equipment;

wherein the circuitry is further configured in response to receiving the information derived from the single user identification to receive data over a downlink shared channel, wherein the received data associated with the group of user equipments is point to multipoint data and the received data associated with the single user equipment is point to point data; and

wherein the received data associated with the group of user equipments is received in a first transmission time interval (TTI) and the received data associated with the single user equipment is received in a second TTI.

2. The user equipment of claim 1 wherein the circuitry is further configured to transmit channel quality information and antenna weight information.

3. The user equipment of claim 2 wherein in response to the transmitted channel quality information and antenna weight information, the circuitry is further configured to receive modulation code scheme (MCS) information for the received data associated with the single user identification.

4. The user equipment of claim 3 wherein in response to the transmitted channel quality information and antenna weight information, the circuitry is further configured to receive the data associated with the single user identification processed using the antenna weight information.

5. The user equipment of claim 2 wherein the channel quality information and antenna weight information is transmitted over a control channel.

6. A base station, comprising:

circuitry configured to transmit at least one downlink control channel having information derived from an identification for a group of user equipments and to transmit data over a downlink shared channel for reception by the plurality of user equipments of the group,

wherein the circuitry is further configured to transmit at least one downlink control channel having information derived from an identification for a single user equipment and to transmit data over a downlink shared channel for reception by a single user equipment, wherein the transmitted data associated with the group of user equipments is point to multipoint data and the transmitted data associated with the single user equipment is point to point data; and

wherein the transmitted data associated with the group of user equipments is transmitted in a first transmission time interval (TTI) and the transmitted data associated with the single user equipment is transmitted in a second TTI.

7. The base station of claim 6 wherein the circuitry is further configured to receive channel quality information and antenna weight information.

8. The base station of claim 7 wherein in response to the received channel quality information and antenna weight information, the circuitry is further configured to transmit MCS information for the data associated with the single user identification.

9. The base station of claim 8 wherein in response to the received channel quality information and antenna weight information, the circuitry is further configured to transmit the data associated with the single user identification processed using the antenna weight information.

10. The base station of claim 8 wherein the channel quality information and antenna weight information is received over a control channel.
