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： In one embodiment, a method in a network node is provided. The network node is configured to use a first power level for transmitting data in subframes of a first type, and to use a second power level for transmitting data in subframes of a second type. The method comprises signaling (520) first and second information to a network entity. From the first information, a power offset for subframes of the first type is derivable. The first power offset represents a relation between a power level for transmitting reference signals and the first power level. From the second information, a power offset for subframes of the second type is derivable. The second power offset represents a relation between the power level for transmitting reference signals, and the second power level.

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.

摘要： Inter-cell interference coordination across layers of a communication network can be implemented by configuring a cell to transmit one or more downlink transmission resources having variably reduced transmission activity. A transmitting node, such as a macro cell, can transmit transmission resources, such as resource elements, resource blocks, subframes, and frames, having reduced transmission activity at varying predictable times according to a selected cell activity pattern. A receiving node, such as a user equipment, can decide to make received signal measurements according to the cell activity pattern.

摘要： Transmitter(s) (34), radio base station nodes (38) comprising transmitter(s), and methods of operating transmitter(s)/radio base station(s) involve handling discontinuous transmission indication bits, particularly when transmitting using a 16 QAM signal point constellation having an I-branch and a Q-branch (for a quadruple of bits comprising two I-branch bits, i1 and i2, and two Q-branch bits q1 and q2). The transmitter(s) (34) and the radio base station nodes (28) comprised thereof are operated to perform a Multimedia Broadcast Multicast Service over Single Frequency Network (MBSFN) transmission wherein the MBSFN transmission comprises mapping data to a Secondary Common Control Physical Channel (S-CCPCH). For the Secondary Common Control Physical Channel (S-CCPCH) the methods include operating a 16 Quadrature Amplitude Modulation (QAM) transmitter (34) according to a predetermined strategy. The predetermined strategy is configured whereby one or more discontinuous transmission indication bits input to the transmitter (34) result in unambiguous determination of output values from an Inphase (I) output and a Quadrature (Q) output.
