摘要： 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.

摘要： Method and arrangement in a relay node, for selecting communication mode. The relay node is configured to communicate with a base station via a donor antenna over a first link and to communicate with a user equipment via a coverage antenna over a second link. The method comprises obtaining an isolation value, based on the radio wave isolation between the relay donor antenna and the relay coverage antenna. The obtained isolation value is compared with an isolation threshold level value. The relay node is configured to communicate in full duplex mode if the obtained isolation value exceeds the isolation threshold level value, otherwise in half duplex mode. Information concerning the configured duplex mode of the relay node is transmitted to the base station.Also a method and arrangement in a base station is described.

摘要： According to various embodiments, a method is provided at a relay node for enabling subframe allocation between a backhaul link and an access link of the relay node. The relay node is connected to a controlling entity via the backhaul link, and is connectable to at least one user equipment via the access link. The relay node receives a trigger or configuration information from the controlling entity from the controlling entity. Based on the received trigger or configuration information, the relay node sends information to the controlling entity, indicating a resource utilization of the access link and/or indicating a quality of the access link.

摘要： Automatically adjust the size of a Physical Uplink Control Channel, PUCCH, of an uplink communication subframe. In a particular embodiment, the size of a semi-static region of the PUCCH is adjusted. The adjustment is based on a utilization factor of the PUCCH over a time period. The adjustment can also be based on the connection factor (connections between the wireless terminals and the cell) and/or based on the utilization factor of a PUSCH (Physical Uplink Shared Channel). The result is an efficient resource utilization on the PUCCH, and a properly dimensioned PUCCH region.

摘要： A method for power measurements in a cellular communication system comprises receiving measurement configuration orders. Operation of a power meter is controlled in dependence on the measurement configuration orders. Reference signal received powers are measured. A measurement report is compiled and transmitted. The measurement configuration orders comprise cell status information associated with neighbouring cells and measurement instructions that are dependent of the cell status of respective cell. The cell status information comprises information about whether the neighbouring cell is of a different type than the serving cell. Controlling of the operation of the power meter and/or compiling of the measurement report is performed in dependence on the cell status of the neighbouring cell. A method for handover based on such measurement reports is also disclosed as well as Node Bs and user equipments configured to perform such methods.

摘要： This document proposes soft activation and inactivation of (network) repeaters that are, for example, activated on an as-needed basis. With soft activation, repeater gain ramps upward at a controlled rate, thereby avoiding rapid changes in interference caused by the repeater. Likewise, with soft inactivation, repeater gain ramps downward at a controlled rate. Soft activation/inactivation results in more gradual changes in the interference contribution of the repeater, thereby improving the performance of interference-compensating radio receivers operating in proximity to the repeater.

摘要： In accordance with one embodiment of the present disclosure, a method of operating a relay node includes receiving information, at the relay node, information identifying a plurality of subframes. The subframes represent time periods during which a base station may grant the relay node permission to transmit to the base station on a first frequency. The method also involves selecting one of the identified subframes to be used for a transmission between the relay node and a wireless terminal on the first frequency and transmits to the wireless terminal a scheduling grant granting the wireless terminal permission to transmit information on the first frequency during the selected subframe.
