Abstract: Systems and methodologies are described that facilitate performing antenna virtualization in a wireless communication environment. A set of physical transmit antennas can be partitioned into a plurality of groups of physical transmit antennas. Further, a precoding vector for a particular group of physical transmit antennas from the plurality of groups of physical transmit antennas can be formulated. Moreover, the particular group of physical transmit antennas can form a particular virtual antenna. By way of another example, a disparate precoding vector for a disparate group of physical transmit antennas from the plurality of groups of physical transmit antennas can be formulated, and the disparate group of physical transmit antennas can form a disparate virtual antenna. The precoding vector can be applied to a signal for transmission over the particular virtual antenna, and the disparate precoding vector can be applied to a disparate signal for transmission over the disparate virtual antenna.

Abstract: Systems and methodologies of intelligently selecting and advertising antenna ports to UEs (e.g., advertising a number of antenna ports to legacy UEs, and another number of antenna ports to new UEs). Such adaptive feature in adjusting the number of antenna ports, enables the base station(s) to intelligently balance requirements of legacy UEs and new UEs (e.g., LTE-A) for an overall efficient operation of the wireless system take as a whole - (e.g., performance gain for new users is deemed an offset for performance degradation for legacy users.) Accordingly, resources that are typically reserved for a Reference Signal (RS) associated with an antenna port, can be freed when such antenna ports are not advertised to the UEs as part of wireless system operation.

Abstract: Systems and methodologies are described that facilitate creating antenna ports to correspond to two or more groups of user equipment (UEs). The subject innovation can organize two or more groups of user equipment and signal to each of the two or more groups a respective antenna port. The subject innovation can further communicate mapping information, a reference signal, or delay related to a linear combination in order to identify antenna ports. Based on such communicated information, the reference signal can be decoded in order to identify each antenna port.

Abstract: SUPPORTING MULTIPLE ACCESS TECHNOLOGIES IN A WIRELESS ENVIRONMENTSupport for multiple wireless access technologies at a common terrestrial radio access network is described herein. By way of example, wireless resources can be reserved in a manner that facilitates transmission of control and reference signals to advanced or emerging-technology user terminals (e.g., LTE-A), while mitigating adverse affects on legacy user terminals (e.g., LTE Release 8). As such, information designated for LTE-A terminals can be embedded in predetermined reserved locations, which exploit known standardized behavior of legacy terminals in expecting information at specific locations. Such reserving of resources can occur typically without the legacy terminals being affected, mitigating or avoiding performance degradation for legacy terminals.Figure 5

Abstract: Systems and methodologies are described that facilitate sending and/or receiving user equipment specific reference signals (UE-RSs) in a wireless communication environment. A UE-RS pattern can be selected, yielded, etc. based upon a number of symbols from a subframe utilized for downlink transmission. At least one time domain component of the UE-RS pattern can vary based upon the number of symbols from the subframe utilized for the downlink transmission. For instance, the at least one time domain component can be punctured, time-shifted, and so forth. Further, UE-RSs can be mapped to resource elements of the subframe as a function of the UE-RS pattern. Moreover, a UE can utilize the UE-RS pattern to detect UE-RSs on the resource elements of the subframe. Further, the UE can estimate a channel based upon the UE- RSs.
