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: 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.

Abstract: Sistemas y metodologías para seleccionar y anunciar de forma inteligente puertos de antena a los UE (por ejemplo, anunciando un número de puertos de antena a los UE de legado, y otro número de puertos de antena a los nuevos UE); dicha característica adaptable en el ajuste del número de puertos de antena, permite a la estación base equilibrar de forma inteligente los requerimientos de los UE de legado y los nuevos UE (por ejemplo, LTE-A) para una operación eficiente general del sistema inalámbrico tomado como un todo (por ejemplo, la ganancia de rendimiento para los nuevos usuarios se considera una compensación para la degradación del rendimiento para usuarios de legado); por consiguiente, los recursos que típicamente están reservados para una Señal de Referencia (RS) asociada con un puerto de antena, pueden ser liberados cuando dichos puertos de antena no son anunciados a los UE como parte de la operación del sistema inalámbrico.

Abstract: Systems and methods for providing coverage to a first cell (104i) through a first antenna system (106i) and coverage to a second cell (104 j) through a second antenna system (106g). Data is also processed for transmission to a mobile device (108i) in the first cell using the first and second antenna systems.

Abstract: Systems and methodologies are described that facilitate employing flexibl e signaling of resource block assignments on a control channel. Resource blo cks associated with an uplink or downlink channel can be split into a plural ity of groups, and group-specific signaling constraints can be utilized with each of these groups. For example, the group-specific signaling constraints can relate to minimum resource block allocation units, signaling structures (e.g., bitmap structure, contiguous allocation structure, tree-based struct ure, ), and the like utilized for sending assignment indications that alloca te resource blocks within the respective groups. Further, an access terminal can have a common understanding of the group-specific signaling constraints ; thus, a received assignment indication can be deciphered by the access ter minal by utilizing the group-specific signaling constraints.

Abstract: Methods, systems, and devices for wireless communications are described. A wireless device such as a user equipment (UE) may receive a first downlink shared channel transmission over a first set of frequency resources in a first transmission time interval (TTI); receive a downlink control transmission including a grant of a second set of frequency resources of a second TTI for a second downlink shared channel transmission, the downlink control transmission including an indication that a demodulation reference signal of the first downlink shared channel transmission is reused for the second downlink shared channel transmission; determine to rate match the second downlink shared channel transmission around resources of the second set of frequency resources that are not part of the first set of frequency resources, and receive the second downlink shared channel transmission over a subset of the second set of frequency resources.
