Methods And Apparatus For Supporting Communications Using A First Polarization Direction Electrical Antenna And A Second Polarization Direction Magnetic Antenna

View page
US Patent:
8326249, Dec 4, 2012
Filed:
Mar 6, 2008
Appl. No.:
12/043860
Inventors:
Juergen Cezanne - Ocean Township NJ,
Saurabha R. Tavildar - Jersey City NJ,
Bikram Reddy Anreddy - Bridgewater NJ,
Xinzhou Wu - Monmouth Junction NJ,
Rajiv Laroia - Far Hills NJ,
Assignee:
QUALCOMM Incorporated - San Diego CA
International Classification:
H04B 1/06
H04B 7/00
US Classification:
455272, 455269
Abstract:
A communications device, e. g. , a mobile wireless terminal, includes a plurality of antennas having different associated polarization directions. The plurality of antennas includes an electrical antenna, e. g. , a dipole antenna and a magnetic antenna, e. g. , a loop antenna or a slot antenna. In one embodiment the electrical antenna is used for receiving and/or transmitting signals associated with a vertical polarization direction, while the magnetic antenna is used for receiving and/or transmitting signals associated with a horizontal polarization direction. In some embodiments different data streams are communicated concurrently via the electrical and magnetic antennas. Methods for operating the communications device to switch between the electrical and magnetic antennas and/or to control reception and/or transmission are described. The novel antenna configuration facilitates the use of the horizontal polarization direction communications between the communications device and a base station without the need for directionally azimuth positioning the magnetic antenna.

Mitigating Interference In A Communication Network

US Patent:
2012026, Oct 18, 2012
Filed:
Jun 25, 2012
Appl. No.:
13/532477
Inventors:
Junyi Li - Chester NJ,
Saurabha Tavildar - Jersey City NJ,
Rajiv Laroia - Far Hills NJ,
Thomas Richardson - South Orange NJ,
Assignee:
QUALCOMM Incorporated - San Diego CA
International Classification:
H04B 15/00
H04L 27/00
H04L 27/28
US Classification:
375260, 375285, 375295
Abstract:
Aspects relate to mitigating interference in a communication network that does not employ a centralized scheduler. A transmission sent on a subset of resources is evaluated to determine a number of communication pairs that have selected that subset of resources on which to transmit. If there are a large number of communication pairs transmitting on that subset, the transmission is ignored by a receiving device. The number of degrees of freedom that contain energy on the subset is evaluated to determine if an expected number of degrees of freedom that should have energy is met or exceeded. If the expected threshold number is met or exceed, the transmission is decoded by the receiving device, else the transmission is not decoded.

US Patent:
2013031, Nov 28, 2013
Filed:
Jul 29, 2013
Appl. No.:
13/953512
Inventors:
Rajiv Laroia - Far Hill NJ,
Saurabha R. Tavildar - Jersey City NJ,
Thomas J. Richardson - South Orange NJ,
Xinzhou Wu - Monmouth Junction NJ,
Leonard Henry Grokop - San Diego CA,
Assignee:
QUALCOMM Incorporated - San Diego CA
International Classification:
H04W 48/16
US Classification:
370254
Abstract:
Systems and methodologies are described that facilitate identifying peers based upon encoded signals during peer discovery in a peer to peer network. For example, direct signaling that partitions a time-frequency resource into a number of segments can be utilized to communicate an identifier within a peer discovery interval; thus, a particular segment selected for transmission can signal a portion of the identifier, while a remainder can be signaled based upon tones communicated within the selected segment. Moreover, a subset of symbols within the resource can be reserved (e.g., unused) to enable identifying and/or correcting timing offset. Further, signaling can be effectuated over a plurality of peer discovery intervals such that partial identifiers communicated during each of the peer discovery intervals can be linked (e.g., based upon overlapping bits and/or bloom filter information).

US Patent:
2014001, Jan 9, 2014
Filed:
Jul 9, 2012
Appl. No.:
13/544868
Inventors:
Saurabha Rangrao Tavildar - Jersey City NJ,
Shailesh Patil - Bridgewater NJ,
Hua Wang - Basking Ridge NJ,
Aleksandar Jovicic - Jersey City NJ,
Junyi Li - Chester NJ,
Assignee:
QUALCOMM Incorporated - San Diego CA
International Classification:
H04W 8/00
US Classification:
370254, 370315
Abstract:
Techniques for enabling relay assisted peer discovery in a wireless communication network are disclosed. A relay may receive, from at least one user equipment (UE), at least one hashed expression to transmit. Further, a relay may compute a time dependent hash of the at least one hashed expression to transmit. The relay may broadcast, and the second UEs may receive, the time dependent hash of the at least one hashed expression. The UE may be, for example, an eNodeB. The hashed expression may be a time varied hashed expression.

Method Of Using Ue Discovery For Paging Optimization

US Patent:
2014002, Jan 23, 2014
Filed:
Mar 12, 2013
Appl. No.:
13/797689
Inventors:
Saurabha Rangrao Tavildar - Jersey City NJ,
Michaela Vanderveen - Tracy CA,
Junyi Li - Chester NJ,
Vincent Douglas Park - Budd Lake NJ,
Assignee:
QUALCOMM Incorporated - San Diego CA
International Classification:
H04W 68/02
US Classification:
455437
Abstract:
Methods and apparatus are described for refining, e.g., reducing, a paging area corresponding to a user equipment device, e.g., a cellular inactive UE device. Various embodiments are well suited for communications systems in which user equipment devices participate in peer to peer communications networks in which direct user device to user device communications are employed. A user equipment device participating in a peer to peer network transmits discovery signals. A femto base station and/or a cellular active UE device in the local vicinity of the UE device transmitting the peer to peer discovery signal eavesdrops on the peer discovery signaling and detects the presence of the cellular inactive UE device. The detection of the cellular inactive UE device is reported to a MME. The MME determines a paging area corresponding to the detected UE device based on the reported information and the location of the reporting device.

US Classification:
370255
Abstract:
Techniques for transmitting information in a long term evolution (LTE) wireless communication network are disclosed. A base station may receive a first user equipment (UE) expression and first UE location information of a UE seeking peers. The base station may also receive a second UE expression and second UE location information of at least one of the peers. In accordance with the first and second UE expressions and the first and second UE location information, the base station may match ones of the peers proximate to the UE. The base station may transmit, using a data exchange efficiency technique, information to alert the UE to the presence of the peers. This transmission may comprise wide area network (WAN)-specific signaling.

US Patent:
8189555, May 29, 2012
Filed:
Feb 6, 2009
Appl. No.:
12/367293
Inventors:
Xinzhou Wu - Monmouth Junction NJ,
Pramod Viswanath - Champaign IL,
Saurabha Tavildar - Jersey City NJ,
Junyi Li - Chester NJ,
Assignee:
QUALCOMM Incorporated - San Diego CA
International Classification:
H04J 3/00
US Classification:
370345
Abstract:
Methods and apparatus for communicating information, e. g. , peer discovery information, to peer communications devices using multiple antenna patterns at different times are described. One exemplary method includes transmitting first peer discovery information during a first period of time using a first antenna pattern, and transmitting second peer discovery information during a second period of time using a second antenna pattern which is different from the first antenna pattern. In at least some embodiments the first antenna pattern is a beam antenna pattern and the second antenna pattern is an omni-directional antenna pattern. In some embodiments, an omni-directional antenna pattern is used at least 50% of the time. This allows devices near the transmitting device to quickly obtain peer discovery information while devices further away make take longer to obtain the peer discovery information since they may need for a beam pattern facing their direction to be used.
