    Abstract: Un procedimiento usado en un sistema de comunicaciones inalámbricas para la generación de una señal de referencia, que comprende: identificar (502) al menos dos grupos de equipos de usuario, UE; señalizar (504) un número distinto de puertos de antenas a los al menos dos grupos de UE; y crear (506) un cierto número de puertos de antenas para cada grupo de los UE; en el que cada puerto de antena corresponde a una combinación lineal de un subconjunto de un cierto número de antenas físicas de transmisión y el número de puertos de antenas creados es el número de puertos de antenas señalizados a cada grupo de los UE, y en el que la combinación lineal empleada para distintos puertos de antenas para un grupo específico de los UE es linealmente independiente; y caracterizado por comprender además la transmisión de una primera señal de referencia para cada uno de los puertos de antenas señalizados al primer grupo de los UE usando la combinación linealmente independiente de antenas de transmisión asociadas a cada puerto de antena para el primer grupo de los UE, y transmitir una señal adicional de referencia para cada uno de los puertos de antenas señalizados al otro grupo de los UE, usando la combinación linealmente independiente de antenas de transmisión asociadas a cada puerto de antena para el otro grupo de los UE.

    Abstract: An enhanced physical downlink control channel (e PDCCH) may provide carrier aggregation (CA) enhancements help support new carriers which may not be backwards compatible reduce control channel capacity limitations of coordinated multipoint (CoMP) transmissions and enhance DL MIMO. In wireless communication networks such as Long Term Evolution (LTE) user equipments (UEs) may monitor both a common search space and a UE specific search space in a control region. A search space may comprise a set of channel control element (CCE) locations where a UE may find its PDCCHs. One or more CCEs are used to transmit each PDCCH. Certain aspects provide methods and apparatus for determining a search space comprising a subset of CCEs located on a band edge of available frequency resources and performing a search of the search space to decode at least one PDCCH.

    Abstract: Techniques for dynamically assigning acknowledgement (ACK) resource to a user equipment (UE) are described. For dynamic scheduling, a scheduling message may be used to send scheduling information for a single transmission of data. For semi-persistent scheduling, a scheduling message may be used to send a semi-persistent assignment for multiple transmissions of data. In an aspect, at least one field of a scheduling message, which is normally used to carry scheduling information for dynamic scheduling, may be re-used to carry an ACK resource assignment for semi-persistent scheduling. In one design, a UE may receive a scheduling message carrying a semi-persistent assignment and may obtain an assignment of ACK resource from the at least one field of the scheduling message. The UE may receive a transmission of data sent in accordance with the semi-persistent assignment, determine ACK information for the transmission of data, and send the ACK information with the ACK resource.

    Abstract: Transmit power is controlled for a first uplink data transmission on Physical Uplink Shared Channel (PUSCH) during random access channel (RACH) procedure. Power control adjustment for the first PUSCH transmission is performed relative to the power spectral density used for successful PRACH transmission as adjusted for bandwidth difference, etc. The uplink Physical random access channel carries the RACH information that is transmitted by the user equipment (UE) during registrations or base station originated calls. A PRACH is composed of a number of preambles and a message portion. The preambles are a series of radio frequency power "steps" that increase in power according to the power step setting until the maximum number of preambles is reached or the base station acknowledges. Once the UE receives a positive indication, it transmits the message portion of the PRACH which consists of message data and control data with independent power gain control.

    Abstract: The described aspects include methods and apparatus for aggregating carriers over a backhaul link between a relay and an evolved Node B (eNB). A first set of subframes of at least a first carrier of a plurality of carriers configured for communicating with an eNB over a backhaul link can be determined. A second set of subframes of at least a second carrier of the plurality of carriers configured for backhaul link communications is also determined wherein the second set of subframes are different from the first set of subframes. Data received over a plurality of access link carriers can then be communicated to the eNB over the first carrier and the second carrier based at least on the first set of subframes and the second set of subframes.
