    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: 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: An extended cell search procedure enables more inclusive measurement reports by mobile terminals operating in a heterogeneous network. The mobile terminal may be configured to conduct an extended cell search to enable better detection of signals transmitted from weaker cells. For mobile terminal with extended cell search capabilities, the network sends an extended cell search message to the mobile terminal when there is a need for an extended cell search. In response to the extended cell search message, the mobile terminal uses an extended cell search procedure rather than the normal cell search procedure (as specified in Rel-8 of the LTE standard) when performing cell searches.

    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 (SCCPCH).

    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.
