摘要： The technology involves data processing during intra-site handover procedures. At least two directional antennas of a base station receive user data carrying signals originating from a mobile units positioned in an intra-site handover area defined by the overlapping radio coverage of the antennas. The directional antennas performs an initial data signal detection of the received data signals resulting in detected user data, which typically results in a loss of radio performance of the antenna. The detected user data from the directional antennas is then jointly processed to generate processed user data. The performance loss is compensated by providing differential antenna gain of the directional antennas within the handover area. As a result, a similar radio coverage in this area as prior art solutions is obtained but with a less complex antenna-related design.

摘要： An object of the present invention is to enable coordination of VP/HP polarizations generated by cross-polarized, i.e. orthogonally polarized antenna configurations, of one radio device with another radio device. The object is achieved by a method in a first eNB (100c) of coordinating polarizations of the first eNB with polarizations of an additional eNB (100a). The polarizations are generated by an antenna configuration comprising at least two orthogonally polarized antennas. The first and additional eNB (100c, 100a) communicate wirelessly with a UE (150a). The method comprises the steps of establishing a first amplitude and/or phase offset of the antenna configuration generating a vertical or horizontal polarization, and a second amplitude and/or phase offset of the antenna configuration generating a polarization orthogonal to said polarization generated by the first amplitude and/or phase offset, defining the polarization generated by the first amplitude and/or phase offset to be vertical and the polarization generated by the second amplitude and/or phase offset to be horizontal, determining a polarization of the UE, and coordinating the defined polarizations with polarizations of the additional eNB based on the determined UE polarization.

摘要： A solution is disclosed for minimizing the amount of hardware and hardware accuracy requirements to simultaneously give the feature of both cell and narrow beams transmission, while enabling methods for capacity/coverage increase. The main property utilized by the present invention for maintaining cell-coverage pattern control, when radiating information in two simultaneous beams, is to use orthogonal polarization states for the two beams. The two orthogonal polarization states may for instance constitute linear polarization slanted at +45° and −45°, respectively. The dedicated broadcast transmission needs to be conveyed defining the total cell coverage area. The total cell coverage area is matched by the coverage of the two fixed narrow-beams. The broadcast signal transmission is divided into two signal streams/paths, one for each of the two fixed narrow-beams (no coherency requirements existing between the two parallel signal streams/paths). The two broadcast signal streams/paths are combined by means of combiner units with the dedicated combined signals from all fixed narrow-beam selected users in each of the two branches. The signals to the two antennas are then transmitted having an orthogonal polarization.

摘要： A signal power associated with a signal received in a current time period is determined. The determined signal power is combined with a predicted effective interference to form a predicted signal-to-interference indicator. The predicted signal-to-interference indicator is compared to a target signal-to-interference indicator. One or more transmit power control commands are generated based on the comparison. In one example embodiment, the predicted effective interference is based on an effective interference estimated for a previous time period. In another example embodiment, the predicted effective interference is based on interference contributions estimated in a current time period and a predicted interference cancellation efficiency. The predicted interference cancellation efficiency is based on the estimated interference cancellation efficiency for a previous time period. The technology is particularly useful in receivers that use interference cancellation and achieves excellent transmit power control performance both in terms of accuracy and speed.

摘要： A basic idea of the invention is to provide multi-user resource scheduling and distribution based on balancing the power resources used for the different narrow beams in order to smooth the interference levels over the whole cell, area and to reduce interference fluctuations. The resource scheduling principle according to the invention is especially useful when the available resources are not fully utilized. The idea is to select, for each antenna beam of at least a subset of the antenna beams, at least two mobile users for service using the respective antenna beam during a transmission time interval, and to distribute power resources to the antenna beams for use during the transmission time interval based on the guideline of balancing the power resources among different antenna.

摘要： A control node (26) of a radio access network (24) comprises a soft handover unit (62) and a power control unit (50). The soft handover unit (62) controls a soft handover procedure wherein a user equipment unit (30) has diversity in radio transmissions with plural radio base stations (28) comprising an active set of base stations. The power control unit (50), during the soft handover procedure, facilitates an adjustment of an uplink power level used by the user equipment unit (30) for uplink radio transmissions to the plural base stations by an adjustment amount. The adjustment amount is determined to promote uplink synchronization for all radio base stations of the active set. In one example embodiment, the power control unit (50) comprises a soft handover power boost function (70) which, during the soft handover procedure, increases the uplink power level used by the user equipment unit (30) for uplink radio transmissions by the adjustment amount. The adjustment amount is preferably a function of a difference between power levels of downlink reference signals of the active set.

摘要： Handover is a main function that is used to support mobility in the network. In a cellular communication network having adaptive antennas for enabling narrow beam operation, a network control unit sends a radio link setup request to a selected cell-serving network unit for configuration of a new serving radio link. Before responding to the radio link setup request the cell-serving network unit performs uplink measurements with respect to the mobile unit, and a narrow target beam is selected within a cell served by the cell-serving network unit based on these measurements. The cell-serving network unit then configures the new serving radio link for the considered mobile unit directly with the selected narrow target beam. Consequently the system can perform the handover procedure using narrow beams only, without first establishing the radio link with a cell-wide beam and then reconfiguring the radio link onto a narrow beam.
