METHODS PROVIDING COORDINATION FOR UPLINK (UL) COORDINATED MULTIPOINT (CoMP) RECEPTION AND RELATED NETWORK NODES

摘要

Scheduling information for a wireless device may be transmitted from a first node of a network to the second node of the network wherein the scheduling information defines a plurality of time slots for UpLink transmission from the wireless device. After transmitting the scheduling information to the second node, a UL signaling grant may be transmitted to the wireless device for one of the time slots defined by the scheduling information. A UL transmission may be received from the wireless device at the first node over the time slot of the UL signaling grant. Information may be received from the second node relating to the UL transmission over the time slot of the UL signaling grant. The UL transmission may be processed at the first node using the information from the second node relating to the UL transmission from the wireless device.

1. A method of operating a first node providing communication with a wireless device in a communications network including the first node and a second node, the method comprising:
transmitting scheduling information for the wireless device from the first node to the second node wherein the scheduling information defines a plurality of time slots for UpLink (UL) transmission from the wireless device to the communications network; after transmitting the scheduling information to the second node, transmitting a UL signaling grant to the wireless device for one of the plurality of time slots defined by the scheduling information; receiving a UL transmission from the wireless device at the first node over the time slot of the UL signaling grant; receiving information from the second node relating to the UL transmission from the wireless device over the time slot of the UL signaling grant; and processing the UL transmission from the wireless device at the first node using the information from the second node relating to the UL transmission from the wireless device.
