METHOD AND APPARATUS FOR CROSS-NODE SCHEDULING WITH NON-IDEAL BACKHAUL
First Claim
1. A method in a wireless communication system, said method comprising:
- transmitting a scheduling grant to a User Equipment (UE);
configuring said UE with a configurable time offset; and
said UE transmitting or receiving a communication scheduled by said scheduling grant,said UE transmitting or receiving said communication delayed from said transmitting a scheduling grant by at least said configurable time offset,wherein said wireless communication system is a cross-node system, said transmitting a scheduling grant is carried out by a first node and said UE transmitting or receiving a communication comprises said communication being with a second node, said first and second nodes being different nodes.

Abstract
A method and system for wireless communication system provide for transmitting a scheduling grant to a User Equipment (UE) and configuring the UE with a configurable time offset. The method and system also provide for transmitting a scheduling grant to a node and configuring the node with a configurable time offset. The UE transmits or receives a communication scheduled by said scheduling grant, and this transmitting or receiving a communication is delayed from said transmitting a scheduling grant by the configurable time offset. The configurable time offset may be an integer of multiple orthogonal frequency division multiplexing (OFDM) symbols in some embodiments and postpones or adjusts the UE transmitting or receiving a communication, with respect to a regular start time based on the scheduling grant. The method and system find application in cross-carrier and cross-node systems.
