摘要： A method, User Equipment, UE, (700), and first base station (800) serving a first cell (140) for performing an access request by the UE tor operatively connecting the UE to a second cell (110). The UE (700) obtains radio quality parameters indicating quality of radio reception between the UE and the first and second cells. Based on the obtained radio quality parameters, it is determined whether the UE is in a link imbalance zone (148) where the UE has an option to be connected to both the first cell (140) and the second cell (110). If so, the UE sends access request information, to the first base station (800) and indicates availability of the UE to be redirected to the second cell. The first base station (800) may redirect the UE to the second cell (110) when a load of the first cell ( 140) meets pre-defined load criteria.

摘要： The present invention relates to methods and arrangements for assisting a User Equipment (UE) to determine transmit power to be used on a first uplink component carrier y, wherein the base station is configured to communicate with the UE over a plurality of uplink and downlink component carriers x,y. The UE is aware of path loss parameters associated with a second downlink component carrier x. The method in a base station comprises determining cell specific path loss parameters associated with the component carriers of the base station. The cell specific path loss parameters at least comprises path loss parameters associated with the first uplink component carrier y and a second uplink component carrier x which is paired to the second downlink component carrier x, wherein the second uplink component carrier and second downlink component carrier are within one frequency band. The method comprises the further steps of calculating a pathloss offset, deltaPL(y,x), for the first uplink component carrier y, wherein the pathloss offset deltaPL(y,x) is the pathloss power offset for the first uplink component carrier y with respect to the second uplink component carrier x, and sending the calculated pathloss offset, deltaPL(y,x) to the UE.

摘要： A high-power point and one or more low-power points transmit signals associated with the same cell-identifier in a heterogeneous cell deployment. Coverage areas corresponding to the low-power points fall at least partly within the coverage area for the high-power point, so that mobile stations within range of a low-power point are also within range of the high-power point. Channel-state-information reference symbols, CSI-RS, are transmitted using different CSI-RS resources on different transmission points within the cell, while configuration of CSI- RS measurement resources is conducted on a UE-specific basis. The choice of measurement resources to be used is determined by the network, based on the properties of the channels from the transmission points to the UE. As the UE moves around within the cell, the network tracks the channel properties and reconfigures the CSI-RS resources measured by the UE, to correspond to the resource of the closest transmission point or points.

摘要： A high-power point (110) and one or more low-power points (120) transmit signals that are associated with the same cell-identifier in a heterogeneous cell deployment. The coverage areas corresponding to the low-power points (120) fall at least partly within the coverage area for the high-power point (110), so that mobile stations (130) within range of a low-power point are also within range of the high-power point (110), from a downlink perspective. The same CRS signals are transmitted by both the high-power (macro) point (110) and some or all of the low-power (pico) points (120). At the same time, the network transmits CRS-based PDSCH for a particular UE on both the high-power point (110) as well as on some or all of the low-power points (120). In some embodiments only a subset of the points, e.g., those points that the UE hears sufficiently well, participate in the PDSCH transmission using CRS for channel estimation.

摘要： Techniques for collecting channel-state-information, CSI, feedback in a wireless network that comprises a plurality of geographically separated transmission points (110, 120) include methods in which a set of CSI reference symbol, CSI-RS, resources are identified, which correspond to the union of CSI-RS resources used by multiple transmission points (110, 120) in the primary transmission point's coverage area. A mobile station (130) is configured to measure CSI-RS on a subset of the CSI-RS resources, the subset corresponding to CSI- RS resources used by a subset of the transmission points (110, 120). The mobile station (130) is also configured to assume that no downlink data will be transmitted in the remaining portion of the set of CSI-RS resources. CSI feedback is then received from the mobile station (130), based on measurements of the CSI-RS.
