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： 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 method and an arrangement (800) in a user equipment (420) for reporting Channel State Information, CSI, and a method and an arrangement (1000) in a base station (410) for obtaining CSI are provided. The user equipment (420) is in connection with the base station (410) in a cellular communication network (400).

Coverage areas corresponding to the low-power points (120) fall at least partly within the coverage area for the high-power point, so that mobile stations (130) within range of a low-power point are also within range of the high-power point (110). A low-power point (120) measures timing or frequency, or both, of one or more signals received at the low-power point (120) from the high-power point (110), and adjusts the timing or frequency, or both, of a transmission from the low-power point (120) to a mobile station (130), to align the transmission with signals received by the mobile station (130) from the high-power point (110).

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.
