摘要： In one aspect, the present invention provides a simple method of signaling reference signal muting information to receiving radio equipment, such as items of user equipment (UEs). The reference signals may be positioning reference signals and/or cell-specific reference signals, for example. In one or more embodiments, the present invention proposes a general solution whereby the receiving radio equipment is informed not only on whether muting is used in general in a cell, but also the particular timing and formatting of such muting. Further, the contemplated method provides for the use of dynamic muting patterns, and thus avoids the need for statically defined muting patterns, and provides for coordinated muting control, across two or more network cells. In at least one embodiment, static or less dynamic aspects of the muting configuration is signaled via higher-layer signaling, while lower-layer signaling is used to signal more dynamic aspects of the muting configuration.

摘要： Embodiments herein relate to a method in a user equipment (10) for acquiring system information relating to a cell (11,14) in a radio communications network. The cell (11,14) is served by a network node (12,12′,15) and the user equipment (10) is capable of receiving signals on more than one downlink carrier simultaneously. The user equipment (10) creates autonomous gaps on a downlink carrier, which downlink carrier to use for creating autonomous gaps on is based on a received indication from the network node (12,12′,15) and/or a pre-determined rule. The indication or pre-determined rule specifies the downlink carrier. The user equipment (10) then acquires the system information of the cell (11,14) on the downlink carrier using the created autonomous gaps.

摘要： Time-aligned handover for a mobile device is described herein. The time-aligned handover is achieved by determining a time difference between serving and target cells and determining a target propagation delay based on the time difference. In some cases, the target propagation delay may further be determined based on a serving propagation delay between the serving cell and the mobile device. A target transmission time is calculated based on the target propagation delay. The mobile device uses the target transmission time to time align transmissions to the target cell during handover.

摘要： A method in a user equipment (121) for adjusting a transmit timing of uplink transmissions to a network node (110) in a telecommunications system (100) is provided. The user equipment (121) is configurable with more than one aggregated serving cells. The more than one aggregated serving cells are divided into one or more groups of serving cells based on a timing advance value of each of the aggregated serving cells. The one or more groups of serving cells each comprises a timing reference serving cell. The reception timing of a downlink transmission from a timing reference serving cell is used as a timing reference for the transmit timing of uplink transmissions for the serving cells in the group of serving cells comprising the timing reference serving cell, respectively. The user equipment (121) determines a change to a second timing reference serving cell in a group of serving cells, which second timing reference serving cell is different from a first timing reference serving cell currently being used as the timing reference serving cell for the group of serving cells. Then, the user equipment (121) applies an incremental adjustment of the transmit timing of uplink transmissions for the serving cells in the group of serving cells with respect to a timing reference based on the reception timing of a downlink transmission from the second timing reference serving cell in the user equipment (121).A user equipment, a method in network node and a network node are also provided.

摘要： A radio base station generates a congestion status flag, based on measured resource usage in its cell, and based on performance of sessions in the cell. The flag may be a one bit, or a small number of bits, indicating whether the base station is congested. The flag can be sent to neighbouring radio base stations, for use in determining whether to perform handovers to that radio base station. The flag generated in a radio base station, and the flags generated in neighbouring radio base stations, can also be sent to user equipment in a cell.

摘要： In a radio network in which multiple base stations can communicate with multiple user terminals in a coordinated way, user terminals may be grouped into groups, each group representing a coordination scheme to be used for user terminals in the group. The groups may be chosen, for example, according to path loss or QoS requirements Preferably there are three groups requiring no coordination, multiuser coherent coordination and single user coherent coordination respectively. Grouping may be done dynamically according to one or more of the following factors: —the terminal's signalling overhead —the affordable processing complexity —the traffic load —the radio conditions. The grouping unit may be placed in one or more base stations or in any other suitable unit in the network.
