20090016252 | EXTENDED MICROSLEEP FOR COMMUNICATIONS - Systems and methodologies are described that facilitate operating an access terminal in an LTE based wireless communication environment utilizing extended microsleep. While in non-DRX mode, an access terminal can operate in on state for a first period of time and in extended microsleep state for a second period of time. Further, the first and second periods of time can form a repeating pattern where these periods of time alternate. Thus, the access terminal can turn on its receiver for the first period of time (e.g., decode downlink information while in on state) and turn off its receiver for the second period of time (e.g., inhibit decoding of downlink information while in extended microsleep state). Further, the first period of time in the repeating pattern can be one TTI (e.g., 1 ms) and the second period of time in the repeating pattern can be a plurality of TTIs (e.g., 5 ms). | 01-15-2009 |
20090040982 | Handover In A Wireless Data Packet Communication System That Avoid User Data Loss - An apparatus, method, processor(s), and computer program product avoids user data loss by network-controlled, user equipment assisted handover in a wireless data packet communication system. A wireless receiver receives radio link control (RLC) packet data units (PDUs) from user equipment (UE) being served by a source node. A wireless transmitter commands the UE to handover. A network communication interface transmits RLC Uplink (UL) context from the source node to the target node, and transmits RLC Downlink (DL) initialization message and buffered in-transit DL RLC PDUs from the source node to the target node. | 02-12-2009 |

20110038334 | METHOD AND APPARATUS FOR SEMI-PERSISTENT SCHEDULING FOR MULTIPLE UPLINK VOIP CONNECTIONS - Semi-Persistent Scheduling (SPS) addresses a variable number of sessions between nodes, such as an SPS operation applied on a radio bearer between a Remote evolved Base Node (ReNB) and a Donor evolved Base Node (DeNB). As the number of VoIP connections changes over time, the upper bound of the required uplink grant size also changes. Even if the number of VoIP connections is assumed to be fixed over a period of time, the superposition of “on” and “off” intervals of multiple VoIP calls will require the uplink grant size to change over time much more dynamically. Using a fixed uplink SPS size based on a fixed number of VoIP calls will result in inefficient use of uplink grants, (i.e., reserving more grants than needed) or Physical Downlink Control Channel (PDCCH) signaling overhead for VoIP packets that cannot be served by SPS. A set of solutions are provided for semi-persistently scheduling multiple VoIP connections between a ReNB and a DeNB so as to enhance efficient use of SPS and still meet Quality of Service (QoS) requirement(s) of VoIP traffic. | 02-17-2011 |
20120163235 | CONFIGURATION OF USER EQUIPMENT FOR PEER-TO-PEER COMMUNICATION - Configuring a peer-to-peer (P2P) link in a multi-access wireless network includes receiving P2P configuration information from a base station at a UE supporting P2P communication.

The first UE may send a configuration request message to the base station, and receive a responsive configuration message with the P2P configuration information from the base station, which messages may be Radio Resource Control (RRC) messages supporting P2P. In the alternative, the P2P configuration information may be provided in a system information block (SIB) broadcast by the base station. The P2P configuration information may indicate allocation of physical layer or Medium Access Control resources, or both allocated for P2P communication, and other information. | 06-28-2012 |

Interoperability of multiple devices in the mixed communication network is made possible when the multiple devices generate (i.e. derive) protocol-specific keys using the same network key and common information corresponding to particular network communication protocols. | 09-19-2013 |
20130250810 | TOPOLOGY DISCOVERY IN A HYBRID NETWORK - Systems and methods provide a discovery protocol allowing nodes that are interested in knowing a network topology to discover other nodes in the network topology. The discovery protocol includes two message types, topology discovery messages and topology query messages. A node issues topology discovery messages upon powering up, at periodic intervals, or upon detecting a change in network topology. The topology discovery messages are broadcast to all nodes on a network and identify the issuing node to the network. A topology query message is sent to a particular node and requests a response from the receiving node regarding the neighboring nodes of the receiving node. The querying node can use the response data to discover other nodes and to send the discovered nodes query messages such that the node can determine a network topology to a desired level of depth within the network. | 09-26-2013 |
20140105227 | DETERMINATIVE SEGMENTATION RESEGMENTATION AND PADDING IN RADIO LINK CONTROL (RLC) SERVICE DATA UNITS (SDU) - A transmission entity (e.g., user equipment (UE)) is expected to reduce the segmentation of Radio Link Control (RLC) Service Data Units (SDUs) while also minimizing padding. Signaling or provisioning of a constraint value such as a maximum padding amount or minimum segmentation size is employed in a determinative way in the UE to balance these objectives. A receiving entity (e.g., evolved base node (eNB)) benefits from being able to signal these parameters, whose application to RLC instances can discriminate between data and signaling radio bearers. Compliance can also be voluntary, such as the network entity employing at least a portion of the same approach on the downlink. | 04-17-2014 |

20090060888 | Regulated transcription of targeted genes and other biological events - Dimerization and oligomerization of proteins are general biological control mechanisms that contribute to the activation of cell membrane receptors, transcription factors, vesicle fusion proteins, and other classes of intra- and extracellular proteins. We have developed a general procedure for the regulated (inducible) dimerization or oligomerization of intracellular proteins. In principle, any two target proteins can be induced to associate by treating the cells or organisms that harbor them with cell permeable, synthetic ligands. To illustrate the practice of this invention, we have induced: (1) the intracellular aggregation of the cytoplasmic tail of the ζ chain of the T cell receptor (TCR)-CD3 complex thereby leading to signaling and transcription of a reporter gene, (2) the homodimerization of the cytoplasmic tail of the Fas receptor thereby leading to cell-specific apoptosis (programmed cell death) and (3) the heterodimerization of a DNA-binding domain (Gal4) and a transcription-activation domain (VP16) thereby leading to direct transcription of a reporter gene. | 03-05-2009 |
