摘要： Supplemental node transmission assistance in a wireless network provides for transmissions between a wireless network and wireless user equipment in a first direction using a serving node of the wireless network while providing for transmissions between the wireless network and wireless user equipment in a second direction using a supplemental node of the wireless network. The supplemental node is selected based on providing better channel conditions between the network and the user equipment in the second direction than the serving node. The supplemental node thus provides transmission assistance for the serving node in order to provide the best available downlink and uplink communications between the user equipment and the network.

摘要： A method and system for formulating an SINR metric for cells using only the existing RSRP and RSRQ measurements. With this method and system side information is exchanged between eNBs of an E-UTRAN using the X2 interface where the X2 interface carries the X2 Application Protocol (X2AP). The side information is introduced either within X2AP messages exchanged between NB nodes or via modification of existing X2AP messages. Serving cell system information block (SIB) messages may also be modified or new SIB messages introduced to facilitate computation of an SNIR metric at a UE.
