A method for limiting Channel Quality Indicator (CQI) reporting from a User Equipment to a network node is provided where a User Equipment can transmit CQI reports to a network node, such as e.g. a base station, when the User Equipment is operating in low transmission and/or low reception activity mode. A limited CQI reporting is obtained by triggering the reporting according to one or more predefined rules, which to at least some extent depend on CQI specific information provided to the User Equipment from the network node. A User Equipment and a network node adapted to operate in accordance with the suggested method are also provided.

Method apparatus and network node for applying conditional CQI reporting

The present invention relates to methods, a user equipment and a radio base station in a communication network, in which a downlink out-of-coverage is detected based on measurements done on a common channel or on the combination of common and dedicated channels. The out-of-coverage is then reported to the network, either using resources proactively assigned to the user equipment, or by transmitting a predetermined pattern of signature sequences assigned to the user equipment.

A controller for controlling a light source module including a first LED array and a second LED array includes a power input terminal, a first power output terminal and a second power output terminal. The power input terminal is operable for receiving electric power from a power converter. The first power terminal is coupled to the first LED array, and the second power output terminal is coupled to the second LED array. The controller is operable for delivering the electric power to the first LED array via the first power output terminal in a first sequence of discrete time slots, and for delivering the electric power to the second LED array via the second power output terminal in a second sequence of discrete time slots. The first sequence of discrete time slots and the second sequence of discrete time slots are mutually exclusive.

A device () receives consecutive negative acknowledgments (NACKs) (), measures a downlink channel quality () associated with the device (), and triggers autonomous retransmission () when power is limited in the device (), when the device () is using a minimum usable enhanced dedicated channel (E-DCH) transport format combination (ETFC), and when one of a number of consecutive NACKs () is greater than a predefined number or the measured downlink channel quality () is less than a predefined threshold.

Method and arrangement in a base station for scheduling physical resources in a transmission bandwidth to a user equipment served by the base station. The physical resources may be physical channels or radio resource blocks. Some physical resources within the transmission bandwidth are subjected to a performance requirement power restriction value. The method comprises scheduling physical resources based on the performance requirement power restriction value of the physical resources to be scheduled. Also, a method and arrangement in a user equipment for assisting a base station in scheduling physical resources in a transmission bandwidth to the user equipment is described.

Method and arrangement in a wireless communication system

The present invention relates to a method and an arrangement for controlling downlink power in a multi-carrier communication network system. The communication network system comprises communication network nodes () communicating with a plurality of user equipments () on uplink () and downlink () carriers over a radio interface. Downlink transmit power control commands are sent on at least one uplink control channel to support power control for a multiple of downlink carriers. Each transmit power control command is assigned a pre-determined code word known by said user equipment () and said communication network node () and/or different pre-determined slot formats, known by said user equipment () and said communication network node (), are used to integrate different number of transmit power control command based on the number of used downlink and uplink carriers.

A signaling mechanism is provided to indicate to the user equipment which mode is currently in use for uplink and/or downlink transmission in a system supporting different transmission modes of a multicarrier radio system, such as a HSPA system or another radio system. Using such signaling a particular mode can be dynamically or semi-dynamically activated according to the need, UE reported events or measurements, BS measurements, type of service, DRX cycle in use etc.

Multicarrier transmission method and apparatus

A common uplink timing adjustment parameter value is estimated for UE transmissions in the multi-RAT communications network and provided for transmission to one or more UEs. That signaling parameter value is common to both the first and second RATs and useable by the one or more UEs to adjust transmit timing of uplink carriers belonging to the different RATs. The common timing adjustment parameter value may be provided, for example, in order to coordinate UE transmit timing of a first uplink carrier associated with the first RAT and of a second uplink carrier associated with the second RAT. A multi-RAT UE concurrently receives a first downlink carrier associated with the first RAT and a second different downlink carrier associated with the second RAT. The UE receives the common timing adjustment parameter value on one of those downlink carriers and adjusts a transmit timing of a first uplink carrier associated with the first RAT and of a second uplink carrier associated with the second RAT.

A device () receives a radio link control (RLC) protocol data unit (PDU) () or service data unit (SDU) () to be segmented, defines a padding threshold () for a segmentation mechanism, and determines a padding ratio () after enhanced dedicated channel transport format combination (ETFC) selection (). The device selects a first transport block () and a second transport block () associated with the RLC PDU/SDU () when the padding ratio () is greater than or equal to the padding threshold (), and generates a modified segmentation of the RLC PDU/SDU () based on the first and second transport blocks () when a padding ratio (RTB) associated with the first and second transport blocks () is less than the padding threshold () and a size ratio (STB) associated with the first and second transport blocks () is within a size threshold ().
