摘要： Systems, methods, and apparatuses for phase-rotated reference signals are provided. In accordance with one implementation, phase-rotated reference signals are transmitted from multiple transmit antennas on the same reference signal (RS) resource elements. The receiver may determine channel coefficients for links corresponding to the multiple antennas, based on the received signals at the RS resource elements. Time-domain filtering or frequency-domain orthogonal codes may be used to determine the channel coefficients for links corresponding to the multiple antennas. The phase-rotation information may be broadcasted in a system information block (SIB) message or signaled in a radio resource control (RRC) message.

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： User equipment (UE) architecture for inter-device communication in wireless communication systems is provided. A UE may communicate directly with another UE over a direct inter-device communication link when they are located in proximity. Long term evolution (LTE) downlink or uplink radio resources may be used for communications over the inter-device communication link. The UE may simultaneously maintain an active communication link with its serving base station while communicating with other UEs over the inter-device communication link. To communicate with the base station and other UEs simultaneously, the UE may include additional transmit or receive chain to support the inter-device communications over the inter-device communication link.
