摘要:
Methods and nodes for coordinating uplink transmissions in a victim cell and in an aggressor cell. The uplink transmissions in the aggressor cell potentially cause interference at a victim radio node receiving or measuring uplink signals transmitted in the victim cell. A coordinating node obtains (200) an indication of an uplink pattern of interference-protected resources in frequency and time where uplink transmissions are allowed to be scheduled in the victim cell but not in the aggressor cell. The coordinating node then signals (202) the indication to an aggressor radio node serving the aggressor cell and/or to the victim radio node. When a radio node receives (204) the signaled indication, it uses (206) the uplink pattern for scheduling uplink transmissions in one or both of the victim cell and the aggressor cell, or for configuring a measurement or signal reception. The coordinating node may be the victim radio node (302), or the aggressor radio node (300), or a network node (304) signalling the indication to one or both of the victim radio node and the aggressor radio node.

The present invention relates to multimedia broadcast and multicast services, MBMS, in a cell wherein variable transmission bandwidth is employed. In particular the invention relates to transmission of MBMS control information relating to broadcast and multicast services. According to the method and arrangement of the invention the manner in which the transmission of MBMS control information is performed and/or the content of the MBMS control information is determined based on the amount and the portion of the cell bandwidth that is used for MBMS transmission.

There is provided a method for use in a user equipment when the user equipment is in idle mode or any other low activity state, and when the user equipment bandwidth is smaller than the cell transmission bandwidth. The method comprises the steps of determining a paging position of the user equipment in the frequency domain; receiving, from the network, paging information within the user equipment reception bandwidth; and changing, if indicated by the network, the paging position of the user equipment within the cell transmission bandwidth.

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.

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.

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).
摘要:
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.
