US Patent:

20130265928, Oct 10, 2013
Filed:

Mar 18, 2013
Appl. No.:

13/845278
Inventors:

Marta Martinez Tarradell - Hillsboro OR, US
Sangeetha L. Bangolae - Beaverton OR, US
Mo-Han Fong - Sunnyvale CA, US
Ali T. Koc - Hillsboro OR, US
Satish C. Jha - Hillsboro OR, US
International Classification:

H04W 52/02
US Classification:

370312
Abstract:

In accordance with some embodiments, a new discontinuous reception (DRX) parameter change may be received in user equipment while the user equipment is using an existing DRX parameter. The user equipment continues to use the existing parameter and determines when a new discontinuous reception cycle is starting. The change to the next discontinuous reception parameter is implemented in the new discontinuous reception cycle. In some embodiments by having an agreed upon time to implement the change to the new parameter, signaling between an enhanced node B and user equipment may be reduced. Signaling overhead is a serious impediment to achieving high efficiency in wireless communications.

Marta Martinez Tarradell - Hillsboro OR, US
Mo-Han Fong - Sunnyvale CA, US
International Classification:

H04W 52/02
US Classification:

370311
Abstract:

Embodiments of user equipment (UE) and base stations (eNodeB) and method for reducing power consumption in UE in a wireless network are generally described herein. In some embodiments, characteristics of UE including mobility, communication data load, and communication type are used by base stations, MME or other controlling entities to configure power saving features of the UE. Power saving features can include a new Radio Resource Control (RRC) layer state where circuitry is powered off for extended periods of time, extended Discontinuous Reception (DRX) cycles, reduced workloads in existing RRC, EPC Connection Management (ECM) and/or EPS Mobility Management (EMM) states or combinations thereof.

US Patent:

20130301500, Nov 14, 2013
Filed:

Dec 19, 2012
Appl. No.:

13/719362
Inventors:

ALI T. KOC - Hillsboro OR, US
MARTA MARTINEZ TARRADELL - Hillsboro OR, US
SANGEETHA L. BANGOLAE - Beaverton OR, US
SATISH C. JHA - Hillsboro OR, US
RATH VANNITHAMBY - Portland OR, US
JING ZHU - Portland OR, US
International Classification:

H04W 52/02
US Classification:

370311
Abstract:

Systems and methods are disclosed for communicating enhanced user equipment (UE) assistance information between nodes in wireless communication systems. The UE achieves power savings and latency requirements more effectively by communicating its preferences, constraints and/or requirements to an evolved Node B (eNodeB) in the form of UE assistance information. The UE assistance information may include, for example, an indication of a preferred set of discontinuous reception (DRX) settings, current data traffic conditions, expected data traffic conditions, power or performance preferences, and/or an indication of the UE's mobility between cells.

Selective Joinder Of Machine-Type Communication User Equipment With Wireless Cell

US Patent:

20130303166, Nov 14, 2013
Filed:

Jan 7, 2013
Appl. No.:

13/735952
Inventors:

Puneet Jain - Hillsboro OR, US
Sangeetha Bangolae - Beaverton OR, US
Marta Martinez Tarradell - Hillsboro OR, US
Mo-Han Fong - Sunnyvale CA, US
International Classification:

H04W 36/22
US Classification:

4554352
Abstract:

Embodiments are described herein for selective joinder of wireless cells by machine-type communication (“MTC”) user equipment (“UE”). An MTC UE may detect a plurality of wireless cells, each provided by an evolved Node B (“eNB”). The MTC UE may detect eNB categories associated with individual wireless cells of the plurality of wireless cells, and may identify one or more wireless cells of the plurality of detected wireless cells on which MTC traffic is permitted based on the associated eNB categories. The MTC UE may selectively join a wireless cell of the one or more identified wireless cells based on a cell selection criterion. Additionally, an eNB may provide a wireless cell and provide, to an MTC UE, an MTC policy that identifies a circumstance under which the eNB will permit MTC traffic. The eNB may be configured to selectively serve the MTC UE based on the MTC policy.

US Patent:

20130315217, Nov 28, 2013
Filed:

Sep 28, 2011
Appl. No.:

13/997222
Inventors:

Sherry S. Chen - Portland OR, US
Marta Martinez Tarradell - Hillsboro OR, US
International Classification:

H04W 72/08
US Classification:

370336
Abstract:

Techniques to train a personal area network component may include obtaining a packet error rate from a personal area network component. It may be determined that the packet error rate is greater than a packet error rate threshold after a time period. A reservation may be requested from a wide area network component based a first transmit pattern from the personal area network component. A second or adjusted transmit pattern from the wide area network component may be received. Personal area network signals may be transmitted based on the second transmit pattern. The time period may be adjusted based on a personal area network packet error rate of the second transmit pattern. Other embodiments are described and claimed.

US Patent:

20130343236, Dec 26, 2013
Filed:

Sep 30, 2011
Appl. No.:

13/997255
Inventors:

Sherry Chen - Portland OR, US
Marta M. Tarradell - Hillsboro OR, US
International Classification:

H04J 3/16
US Classification:

370278
Abstract:

Technology for reducing interference in collocated radios is disclosed. One method comprises identifying a repeating transmit/receive (Tx/Rx) pattern for multiple radios located in a mobile communication device having a Bluetooth radio collocated with an OFDMA radio. A persistent reservation is requested for at least one sub-frame from the OFDMA radio when the repeating Tx/Rx pattern indicates a Bluetooth packet wherein the Bluetooth radio can not transmit without interference with the OFDMA radio. The repeating Tx/Rx pattern is modified based on the persistent reservation. The Bluetooth radio can communicate based on the modified repeating Tx/Rx pattern to enable interference free communication for the Bluetooth radio and the OFDMA radio in the multi-radio mobile communication device. A collocated WiFi radio's transceiver can align its Tx/Rx with the Tx/Rx pattern, and transmit and receive at the same time slots that other collocated radios are transmitting, and receiving.

US Patent:

20140010140, Jan 9, 2014
Filed:

Dec 16, 2011
Appl. No.:

13/995165
Inventors:

Marta Martinez Tarradell - Hillsboro OR, US
Assignee:

Intel Corporation - Santa Clara CA
International Classification:

H04W 4/06
US Classification:

370312
Abstract:

Briefly, in accordance with one or more embodiments, if two or more deices belong to a multicast group, a media access control (MAC) message may be transmitted to the multicast group as a multicast message to provide parameters and/or instructions to the devices. If the devices are in an idle mode, the MAC message may be transmitted during a paging listening interval. A group message may be transmitted as a multicast message to one or more devices in one or more groups in order to assign, reassign, or update the group identifier or multiple devices. If an acknowledgment message was not received by one or more the devices, the group message may be transmitted as a unicast message to the one or devices from which no acknowledgment message was received.
