20100238854 | SIGNALING MECHANISMS FOR NETWORK-RELAY INTERFACE WITH REDUCED OVERHEAD - Relay reporting in a wireless network is implemented by efficiently allocating radio resources based on the nature or criticality of the type of relay report. According to an embodiment, a method of communicating with a relay located in a wireless network includes instructing the relay when to transmit reports based on a mapping of different categories of relay reports to one or more different reporting schemes. Reports are received from the relay based on the relay report category and the corresponding reporting scheme. According to another embodiment, a method of reporting information from a relay to a network node of a wireless network includes generating different categories of reports at the relay for transmission to the network node. A reporting scheme associated with each report category is identified and each report is transmitted to the network node in accordance with the reporting scheme identified for the corresponding report category. | 09-23-2010 |
20110170449 | Frequency Selective SINR Regeneration - A method is performed by a device in a wireless network. The method includes receiving a transmission that includes a wideband channel quality indicator, determining a received signal power estimate for each frequency band of a frequency domain, and determining an average interference-plus-noise based on the wideband channel quality indicator and the received signal power estimate. The method further includes determining a signal-to-interference-plus-noise ratio estimate for each frequency band based on the average interference-plus-noise and the received signal power estimate, and performing a communicative operation based on the signal-to-interference-plus-noise ratio estimate. | 07-14-2011 |
20120039207 | Link Adaptation with Aging of CQI Feedback Based on Channel Variability - According to teachings presented in this document, reported channel quality information, as used for controlling one or more aspects of wireless transmission, is compensated according to an aging function that depends on channel variability. In this manner, the “amount” or extent of age-based compensation applied to the channel quality feedback for a given user—e.g., a mobile station or other item of user equipment—varies as function of that user's channel conditions. More particularly, in an advantageous approach, the aging function applied to the channel quality estimates received from a given user depends on estimates of that user's channel variability. Channel quality estimates from (or generated for) a user whose channel conditions are changing very little, or at least are changing very slowly, may be aged less aggressively than those associated with a user whose channel conditions are changing more rapidly. | 02-16-2012 |
20120195226 | Method and Arrangement in a Wireless Communication System - Method and arrangement in a base station for adjusting a channel quality indicator value of a wireless transmission between the base station and a user equipment. The base station, the user equipment and a relay node are comprised in a multi-hop wireless communication system and adapted to intercommunicate in a first transmission mode and a second transmission mode. The method comprises sending a radio signal to be received by the user equipment, obtaining a measurement of the channel quality indicator value, determining if the transmission mode of the sent radio signal is different from the transmission mode of the obtained channel quality indicator value measurement, and adding a channel quality indicator offset value to the channel quality indicator value, if the transmission mode of the relay node is determined to be the first transmission mode while the channel quality indicator was measured and obtained in the second transmission mode. | 08-02-2012 |
20120294228 | Link Adaptation in Type-II Relay Network - This invention is related to the link adaptation for the downlink transmission in type-II relay network. An method in an eNodeB for adapting link for downlink transmission in type-II relay network, said type-II relay network comprises the eNodeB, one or more relay nodes and a plurality of User Equipments (UE), the method comprises the steps of: classifying the plurality of UEs into two groups: macro-UEs which are served directly by the eNodeB without the help of the one or more relay nodes, and relay-UEs which are served by the eNodeB and the one or more relay nodes; and adapting link for the macro-UEs and the relay-UEs separately. | 11-22-2012 |
