摘要： Equipment for transmitting a signal, the equipment comprising an antenna array ( 600 - 606 ) for providing three or more radiation antenna patterns. The equipment is arranged to transmit a primary common pilot signal with at most two radiation patterns and a secondary common pilot signal with at least one radiation pattern. The equipment comprises controllers ( 622 a- 622 d) for adjusting the power ratio between the primary and the secondary common pilot signal and the total power of the primary and the secondary common pilot signals, and controllers ( 614 a- 614 d) for adjusting the transmit power of the dedicated pilot signal, such that the power levels of the dedicated pilot signals transmitted with the same radiation patterns as the secondary common pilot signal are relatively higher than the power levels of the dedicated pilot signals transmitted with the same radiation patterns as the primary common pilots.

摘要： The invention relates to a data transfer method in a radio system utilizing a multiple antenna method, the data transfer method comprising generating, at a receiver, at least part of a change in a variable which contains transmit filter information on a transmitter as compared with a previous value of the variable, transmitting at least part of the change in the variable containing transmit filter information on the transmitter from the receiver to the transmitter and updating, at the transmitter, the transmit filter information on the transmitter on the basis of the received change in the variable containing transmit filter information. The invention further relates to a radio system implementing the method. In the solution, the amount of data used for updating transmit filter information and to be transmitted to a transmitter can be optimised, which enables unnecessary loading of radio capacity to be avoided.

摘要： The invention relates to a method for controlling the weighting of a data signal in the at least two antenna elements of a first radio connection unit of a radio communications system, which data signal is to be distributed for parallel transmission to a second radio connection unit to at least two beams. In order to improved such a method, it comprises: determining in the second radio connection unit a weight information enabling the first radio connection unit to determine the sets of weights for suitable beams for transmission and transmitting it to the first radio connection unit; and distributing the data signal in the first radio connection unit to those sets of weights and transmitting the data signals simultaneously via the formed beams. Alternatively or additionally, the second unit determines the number of beams to be used and informs the first unit about it. The invention equally relates to corresponding radio connection units, radio connection unit modules and radio communications systems.

摘要： A method, device, and system in which radio links between relays and users are optimized separately from the links between relays and base stations and in which multiple simultaneous data streams between relays and base stations are created. The system includes transceivers of at least three kinds with two kinds of radio interfaces. The first kind of transceiver, a base station (BS), is connected to the core network with a link of wire line quality. The second kind, a relay station (RS), is connected to the BS with a first radio interface, and to the third kind, the user equipment (UE), with a second radio interface. The first and second radio interfaces can operate, at least in part, using the same frequency bandwidth. The UE can also connect directly to the BS using the second radio interface if the BS is closer than any RS.

摘要： A channel quality signaling method and a telecommunication system are provided. The system comprises a base station and one or more user equipment, the base station and the user equipment being configured to communicate with each other using a set of given resources. The system comprises a network element for determining connection information comprising the resources to which the channel quality signaling relates, the user equipment capability, and reference information regarding transmission power used by the base station, a network element for determining connection quality criteria. User equipment is configured to measure a parameter relating to the quality of the received signal from a signal received from a base station, determine an identification of physical connection parameters with which the connection quality criteria may be fulfilled given the determined connection information, and transmit the determined identification to the base station.
