| 20090111503 | Overload indicator for adjusting open loop power control parameters - The exemplary embodiments of the invention include a method, apparatus, and program to determine actions to be taken upon receiving overload indicators. In one exemplary embodiment of the invention, a method includes: determining if more than a first predetermined number of overload indicator messages are received within a first predetermined period of time. If such a determination is made that more than the first predetermined number of overload indicator messages are received within the first predetermined period of time is made, a value of a power output parameter is adjusted by decreasing the value of the power output parameter, and the adjusted value of the power output parameter is sent. If a determination is made that less than a second predetermined number of overload indicator messages are received within a second predetermined period of time, the value of the power output parameter is adjusted by increasing the value of the power output parameter, sending the adjusted value of the power output parameter is sent. | 04-30-2009 |
| 20090316676 | Method and Apparatus for Coupled Sounding - In accordance with an example embodiment of the present invention, an apparatus, comprising a processor configured to derive a time period; and a transmitter configured to transmit a first signal and a second signal to a network element, wherein the second signal is coupled to the first signal in a predetermined way within the time period, is disclosed. | 12-24-2009 |
| 20100173665 | Power Headroom Reporting Method - A method, user equipment, network device, and software product enable a user equipment to determine that at least one of several triggering criterion have been met, in which case the user equipment provides a power control headroom report on an uplink from the user equipment. The triggering criterion includes a threshold having been reached, and the threshold is adjustable via a signal to the user equipment from a base station (such as an eNodeB). | 07-08-2010 |
| 20100202369 | Apparatus, Method and Computer Program Product Providing Harq-Aware Packet Scheduler - Methods and apparatus operative in a wireless communications system divide a communications resource available for performing information transmission and retransmission operations into a plurality of communication resource units. Channel quality information is used to rank each of the communication resource units in terms of channel quality. The communication resource units are divided into a first group having better channel quality and a second group having worse channel quality. The first group of communication resource units having better channel quality is used to transmit new information to a first group of receiving communication devices. The second group of communication resource units having worse channel quality is used to retransmit information to a second group of receiving communication devices. In such a manner simultaneous scheduling of information transmission and retransmission may be accommodated in a 3GPP LTE OFDM based wireless communications system. | 08-12-2010 |
| 20100290509 | System and Method for Efficient Half Duplex Transceiver Operation in a Packet-Based Wireless Communication System - Systems and methods for providing half duplex user equipment in a packet based radio frequency signaling communication system. User equipment with half duplex receiver and half duplex transmitter on IC providing a transceiver capability performs a cycle of receiving downlink messages for a predetermined number of sub frames, shifting to a transmit mode, transmitting uplink messages for the predetermined number of sub frames, shifting to a receive mode, and repeating the cycle of half duplex sub frames. A discontinuous reception function performs a DRX protocol wherein power is reduced to the transceiver for a period of time. A determination is made at the end of the discontinuous reception period to see if the half duplex cycle is at an uplink sub frame; if so, the end of the discontinuous reception is shifted by the user equipment to a downlink sub frame by adding a delay. | 11-18-2010 |
| 20110053601 | Cell Configuration for Self-Organized Networks with Flexible Spectrum Usage - The present invention relates to methods and apparatuses for controlling cell configuration in a cellular network, wherein a cell identity and a local cell spectrum resource entity or profile are assigned to an access device in response to a result of sensing a local radio environment at said access device to detect possible neighbor cells. The assigned local cell spectrum resource entity or profile is used to allocate cell spectrum resource from a shared multi-operator spectrum to said access device. | 03-03-2011 |
| 20110110311 | Exchange of Scheduling Strategies for Interference Coordination - A cell informs surrounding cells about an orthogonal resource allocation strategy of the informing cell so as to induce cooperative behavior among the cells. The informing cell also receives resource allocation strategies from the surrounding cells. Each cell allocates its orthogonal resources according to the mutually exchanged information. The result is to reduce interference in the system. For example, a BS informs other cells on which clusters it generates a small interference, e.g., close UEs concentrated into a particular cluster, and indicate that to its neighbors. Other cells would concentrate UEs which are on the edge to the indicating cell exactly in this cluster. This would mean an “overload invitation”, i.e. inviting the neighbors to produce overload on a particular cluster. If a cell sends an overload invitation on a sufficiently large cluster, this will automatically reduce the interference in the other clusters. | 05-12-2011 |
| 20110211543 | Method and Device for Data Processing in a Cellular Network - Method and a device for data processing in a cellular network are provided, said method including the step of conveying signaling information between base stations over an air interface supporting SON and/or FSU in said cellular network. Furthermore, a communication system is suggested comprising said device. | 09-01-2011 |
