US Patent:

8325661, Dec 4, 2012
Filed:

Aug 26, 2009
Appl. No.:

12/548075
Inventors:

Juan Montojo - San Diego CA, US
Amir Farajidana - San Diego CA, US
Kapil Bhattad - San Diego CA, US
Assignee:

QUALCOMM Incorporated - San Diego CA
International Classification:

H04W 4/00
H04L 12/28
H04J 3/00
US Classification:

370329, 3703954, 370464
Abstract:

Support 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.

Appl. No.:

12/695571
Inventors:

Alexei Y. Gorokhov - San Diego CA, US
Amir Farajidana - San Diego CA, US
Kapil Bhattad - San Diego CA, US
Ravi Palanki - San Diego CA, US
Juan Montojo - San Diego CA, US
Assignee:

QUALCOMM Incorporated - San Diego CA
International Classification:

H04W 4/00
H04B 1/00
US Classification:

370329, 375135
Abstract:

Aspects are disclosed for multiplexing disparate wireless terminals. Resource blocks are mapped according to a hopping pattern. A first and second pair of physical resource blocks are allocated such that the first pair is associated with a first hopping index pair, whereas the second pair is associated with a second hopping index pair. For this embodiment, the first and second hopping index pairs are inversely symmetrical to each other. A pair of distributed resource blocks is also allocated. An assignment is then scheduled that includes a physical resource allocation and a virtual resource allocation. Aspects for operating a wireless terminal are also disclosed. Here, a communication that includes a resource allocation and a reference signal is received. A minimum resource allocation granularity is ascertained from the communication, and a joint channel estimation is based on the reference signal and is a function of the minimum resource allocation granularity.

Filed:

Feb 1, 2010
Appl. No.:

12/697689
Inventors:

Xiliang Luo - San Diego CA, US
Amir Farajidana - San Diego CA, US
Xiaoxia Zhang - San Diego CA, US
Juan Montojo - San Diego CA, US
Assignee:

QUALCOMM Incorporated - San Diego CA
International Classification:

H04L 27/00
US Classification:

375299, 375295
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.

US Patent:

8547954, Oct 1, 2013
Filed:

Aug 25, 2009
Appl. No.:

12/547407
Inventors:

Juan Montojo - San Diego CA, US
Kapil Bhattad - San Diego CA, US
Amir Farajidana - San Diego CA, US
Assignee:

QUALCOMM Incorporated - San Diego CA
International Classification:

H04J 3/00
US Classification:

370345, 370465, 370522, 4555621
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.

QUALCOMM Incorporated - San Diego CA
International Classification:

H04B 7/185
US Classification:

370318, 370329, 370349, 370352
Abstract:

Systems and methodologies are described that facilitate quality of service (QoS) differentiation and/or prioritization across a plurality of base stations included in wireless communication systems. The system can include components and/or devices that obtain resource allocations for cells controlled by a local base station, ascertains whether or not the resource allocations satisfy quality of service targets associated with data flows traversing through cells controlled by the local base station, and dispatches inter cell interference coordination indicators to remote base stations that have a proximate relationship defined by an X2 channel between the local base station and the remote base stations.
