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.

摘要： Systems, apparatuses, and methods may be directed to operating wireless communication resources for a wireless communications system that includes a relay node and a base station. A backhaul link data rate may be identified for a first wireless link between the relay node and the base station. An access link data rate may be identified for a second wireless link between the relay node and a user equipment (UE). The allocation of available resources between the backhaul link and the access link may be adjusted or changed to optimize the allocation of resources.
