Abstract:
A radio network resource controller directs a first network node associated with a first cell region, or a wireless terminal in communication through the first cell region, to measure and report radio resource-related data selected from the group consisting of: resource activity per channel; the number of transmitted power samples that exceed a threshold over a measurement period; and, channel quality samples that exceed a quality threshold. The controller then receives at least one measurement report of the radio resource-related data and, as a function of the radio resource-related data in the first cell region, dynamically reallocates the distribution of resources, such as radio-frequency channels associated with uplink and downlink communications, between the first cell region and at least a second cell region. The invention has a particular advantage in time division duplex (TDD) mode of operation where efficient and dynamic interference mitigation is needed to combat the inherent mobile-to-mobile and base station-to-base station interference.

According to the choice of weights i the weighted function, the user equipment can set its SIR target in a way that either all radio links are able to maintain the TPC BER below or equal to the target TPC BER that is set by the network. The user equipment can also choose the weights such that the target TPC error rate is met only on the serving HS-DSCH.
Abstract:
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.
Abstract:
According to some embodiments of the invention, a method is provided in a radio network node for scheduling data transmission and/or reception. According to the method, the radio network node predicts (530) at least one autonomous gap occurrence in which user equipments served by the radio network node will use autonomously created gaps for acquiring system information from a neighboring base station and during which the UE is not able to receive data from, and/or transmit data to, the radio network node. Furthermore, the radio network node schedules (560) a user equipment for data transmission and/or reception in a time period which does not overlap with any predicted autonomous gap occurrence.

In deployments where there is a mixture of new Node Bs capable of uplink multi-antenna transmission and legacy Node Bs not capable of uplink multi-antenna transmission some embodiments described herein enable a network node (e.g. a radio network controller, RNC) to configure an uplink control channel (e.g. dedicated physical control channel, DPCCH) to be decodable by both the new and the legacy Node 8s when the UE operates in uplink multi-antenna transmission.
Abstract:
A method in a user equipment for controlling transmission from the user equipment, a method in a first radio network node for selecting one or more radio emission control parameters and a user equipment, and a first radio network node configured to perform the methods are provided. The user equipment sends, to the first radio network node, one or more parameters associated with supported duplexer arrangement characteristics of the user equipment for a first operating frequency band. The first radio network node selects the one or more radio emission control parameters based on the one or more parameters associated with the supported duplexer arrangement characteristics of the user equipment for the first operating frequency band. The user equipment receives and applies the one or more radio emission control parameters from the first radio network node such as to control transmission from the user equipment.
Abstract:
The present solution relates to a method in a user equipment (110) for providing navigation signals to a navigator device (104) for use in determining the location of the navigator device. The user equipment (110) selects a plurality of satellites whose signals are to be emulated. After determining the position of the user equipment (110), the user equipment (110) translates the determined position to emulating navigation signals using a parameter derived from each of the respective selected satellites. The user equipment (110) transmits, to the navigator device (104), the emulated navigation signals. The emulated navigation signals enable the navigator device to determine the location of the navigator device (104).

Method and arrangement in a user equipment for adjusting signals transmitted in uplink to a network node, based on a feedback value received from the network node. The method comprises transmitting a signal, to be received by the network node. Further, the method comprises receiving a feedback signal from the network node, providing feedback on the transmitted signal. In addition, the method comprises obtaining a value of a time delay of the received feedback signal. Furthermore, the method comprises adjusting signals transmitted in the uplink according to the received feedback signal, wherein compensation is made for the obtained time delay value of the received feedback signal.
Abstract:
Example embodiments presented herein are directed towards a network node (401A, 401B) (e.g., a source or target base station), and corresponding method therein, for managing a user equipment time offset measurement by accounting for a user equipment mobility profile. The management may involve a source network node (401A) delaying or preventing the sending of a user equipment timing offset measurement to a target network node (401B) or sending an indication or a reliability of the user equipment timing offset measurement. The network node (401A, 401B) may further apply a compensation to the user equipment timing offset measurement to account for an expected behavior of the user equipment based on the mobility profile. The network node (401A, 401B) may also adapt an uplink search window based on the user equipment mobility profile.
Abstract:
An out-of-band relay node (800) reports its composite operating band capability to a donor base station or to another network node. The reported information indicates frequency band support separately for each of the backhaul and access links, which may operate over different frequency bands. In some embodiments, a controlling network node (700) such as a donor base station, an O&M node, an OSS node, a SON node, or another relay node, requests the relay node to report its backhaul link and access link operating frequency band capabilities to the network node. A network node (700) that receives the frequency capability information may use the information to select appropriate frequency bands for access and backhaul link operation and to configure the relay node accordingly. The received frequency band capability information may also be used for one or more network management functions such as radio resources management, network planning, dimensioning, and coverage enhancement.
