摘要： In a heterogeneous cell deployment a mobile terminal may need to receive control data transmissions from a macro node at the same time as a pico node is transmitting user data for the mobile terminal, using the same frequency or set of frequencies. This can result in a problematic interference situation. According to several embodiments of the present invention, at least one of two general approaches is used to mitigate the interference situation described above. In a first approach, the pico node's transmission power is reduced in some time intervals, thereby reducing the interference to a level where reception from the macro node is possible. In a second approach, which may be combined with the first approach in some cases, the data transmitted from the macro node is provided by the pico node, either alone or in combination with the macro node.

摘要： According to the present invention, a receiving node of a telecommunications network (20) (e.g. a radio base station (22) in uplink, or a mobile terminal (24) in downlink) transmits a single acknowledgement message to a transmitting node (e.g. a mobile terminal (24) in uplink, or a radio base station (22) in downlink) in respect of signals received over a plurality of frequency-aggregated carriers (component carriers) (10) between the transmitting and receiving nodes. If all signals are decoded correctly in the receiving node, a positive acknowledgement message (ACK) is sent to the transmitting node; if not all signals are decoded correctly, a negative acknowledgement message (NACK) is sent, or no acknowledgement message is sent. In this way, a single acknowledgement message can be sent for signals received over multiple carriers. The acknowledgement message can have the same format as legacy standards (for example, as specified in Release 8 of the 3GPP specifications), providing compatibility with existing equipment. The number of messages is also reduced compared with the straightforward approach of transmitting individual acknowledgement messages per component carrier.

摘要： The present invention relates to cellular radio communication and in particular to providing information on neighbour cells to enable terminals to perform neighbour cell measurements. In the prior art the terminal attempts to make neighbour cell measurements in a reference signal structure that is the same in the neighbour cell as in the cell the terminal camps in. The present invention is based on the insight that the reference signal structure may differ between neighbouring cell for example in the situation of an MBSFN area that is restricted to a region of all cells of a radio network, or in the situation of TDD mode being applied there may be different regions with different allocation of sub-frames for transmission in the uplink and downlink directions. The present invention solves the problem by broadcast information in a cell indicative of the reference signal structure in neighbour cells.

摘要： Method and apparatus in a communication unit employing a wireless TDD or half duplex FDD transmission arrangement when communicating with a data sending party, for scheduling feedback reports for data blocks in received receive (RX) sub-frames, in transmit (TX) sub-frames available for transmission. An obtaining unit in the communication unit receives allocation parameters for the connection where the number of required feedback reports is greater than the number of allowed feedback reports. A scheduling unit in the communication unit then schedules feedback reports in available TX sub-frames according to a predetermined spreading rule also known by the data sending party, dictating that the feedback reports are spread out or distributed evenly over the available TX sub-frames. In this way, the number of feedback reports in a TX sub-frame can be reduced.

摘要： The invention relates to a method in a first communication device of receiving control information over a radio channel from a second communication device. The first communication device receives a subframe over the radio channel, and determines whether the subframe is a downlink subframe with downlink assignment intended for the first communication device by reading data in the subframe. That being the case, the first communication device decodes data within the subframe, and determines whether any data packet being sent from the second communication device before the subframe has been missed by analyzing an indicator associated to the subframe in the data. The indicator provides knowledge about previous downlink subframes with downlink assignment intended for the first communication device.

摘要： The invention is a method and apparatus for signaling uplink control information in a mobile communication network using carrier aggregation. The signaling mechanism allows the transmission, on a single uplink component carrier, of control information associated with a downlink transmission on multiple aggregated downlink component carriers. Semi-statically reserved resources for the transmission of control information on the uplink component carrier may be dynamically shared by user terminals that are assigned multiple downlink component carriers for downlink transmissions. Implicit or explicit resource indication can be used in combination with dynamic resource indication.

摘要： Method and apparatus for conveying feedback reports from a data receiving party (300) for data received from a data sending party (302) in a wireless connection. A plurality of feedback resources (304) assigned to different feedback information codes are allocated to the data receiving party for transmitting feedback reports. After checking whether the data was received correctly or not, the data receiving party selects a feedback resource (FR2) with a feedback information code that corresponds to one or more feedback reports on the received data. The data receiving party then sends feedback information on the selected feedback resource to the data sending party, thereby conveying the corresponding feedback information code. In this way, multiple feedback reports can be conveyed in a single feedback resource to the data sending party while still retaining single carrier properties.

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.
