1. A method in a wireless network, the method comprising:
- signaling to user equipment a signal indicating the relationship between at least one cell with respect to at least one serving cell transmitting a common multicast transmission;
transmitting at least a portion of the common multicast transmission on the same resource on the at least one serving cell; and
transmitting a pilot signal on the at least one serving cell, the pilot signal related to the at least a portion of the common multicast transmission on the at least one serving cell;
wherein a cell different from the at least one serving cell transmits an interfering signal and a related pilot.

Abstract
A method and apparatus for neighbor assisted combining for localized multicast services. User equipment is sent a signal indicating the relationship between cells with respect to serving cells transmitting a common multicast transmission. At least a portion of the common multicast transmission is transmitted on the same resource on each serving cell. A pilot signal is transmitted on each serving cell, the pilot signal related to the at least a portion of the common multicast transmission on each serving cell. An interfering signal and a related pilot are transmitted on at least one different cell from the serving cells.

10. A method in a wireless device, the method comprising:
-
receiving information regarding serving cells that are transmitting a common multicast transmission; receiving the common multicast transmission, at least a portion of which is transmitted on the same resource element on multiple serving cells; receiving a common broadcast pilot signal related to the common multicast transmission, the common broadcast pilot signal being common to multiple cells; decoding the common multicast transmission; and receiving an interfering signal and a related pilot from a different cell from the serving cells. - View Dependent Claims (11, 12, 13)

14. A network controller comprising:
-
a processor configured to control the operations of the network controller; a serving cell signaling module coupled to the processor configured to signal to user equipment a signal indicating the relationship between cells with respect to serving cells transmitting a common multicast transmission; and a network connection coupled to the processor the network connection configured to send a signal for transmitting at least a portion of the common multicast transmission on the same resource element on each serving cell, the network connection configured to send a signal for transmitting a pilot signal on each serving cell, the pilot signal related to the at least a portion of the common multicast transmission on each serving cell, the network connection configured to send a signal for transmitting an interfering signal and a related pilot on at least one different cell from the serving cells. - View Dependent Claims (15, 16, 17, 18)
