摘要:
A mechanism for controlling resources and/or settings of an access network element like a base station is provided which allows an autonomous reconfiguration of, for example, the antenna configuration based on a set of performance indicators in a base station. The base station can reconfigure itself without the need of operator control so that during periods with low capacity demands the base station will reconfigure correspondingly, which may include a reduction of active cells by turning off the power for a part of the installed equipment.
摘要:
It is disclosed a method including creating inquiry information related to an evaluation of at least one network terminal, and transmitting the created inquiry information in a long-range reference signal; a method including receiving the inquiry information in the long-range signal, establishing, based on the received inquiry information, report information related to a quality of the long-range reference signal, and transmitting the established report information; and a method including receiving the report information, and evaluating, based on the received report information, at least one network terminal.

摘要:
In a method for communicating by radio, a frequency band divided up into a plurality of subcarriers is used for the communication. Messages are sent from a base station to a user station and/or from the user station to the base station. Messages are processed at some times using a first FDMA method such as for example OFDMA and at other times using a second FDMA method such as for example IFDMA. A transmitter and a receiver implement the method.

A method for synchronizing a base station to a mobile station includes transmitting a signal sequence K(i) of length n from the base station to the mobile station. The signal sequence K(i) is formed by repeating a second signal sequence element K2(k) of length n2 n1 times. The second signal sequence is modulated with a first signal sequence element K1(j) of length n1. In the method, n1 is equal to n2 and i, j and k are integers.

A method transmits data packets in a radio system between an emitter and a receiver. A nominal energy is defined for each data packet and each transmission according to a quality requirement for the reception by the receiver. An emission power required for each data packet is determined according to the quality requirement for the reception of the data packet. The transmission data packet is formed from a plurality of data packets. A first transmission emission power is defined for a first transmission of the transmission data packet according to the determined emission powers for the individual data packet. The first transmission of the transmission data packet is carried out with the first transmission emission power. A retransmission emission power is calculated according to a nominal transmission power derived from the nominal energy, for the transmission data packet and the emission power for at least one previous transmission of the transmission data packet.
摘要:
The present invention relates to a method for transmitting data via a physical channel in a communication system, the channel being used by at least one first communication device and one second communication device and transmitting data with a defined bit rate. According to the present invention, the data to be transmitted (TD) is composed of load data (LD) and identification data (ID) for identifying the second communication device, the load data (LD) and identification data (ID) are coded separately from one another, the respective coding (C_LD, C_ID) takes place in such a way that an identical bit rate is achieved after the coding operation for the load data (LD) and the identification data (ID) and the rate is matched to the bit rate that has been defined for the physical channel by a rate matching mode, which defines which bits are punctured or repeated in a data stream. The rate matching model for load data (LD) and identification data (ID) is identical.

The present invention relates to the use of an ARQ method, especially a hybrid-ARQ-method, in order to carry out a reliable packet orientation data transfer, preferably, using a mobile radio system. When requesting a transmission data packet for the bits of the retransmission data packet, a different rate adaptation model is used in comparison with the bits corresponding originally sent data packets. A particular advantage of the present method is that the bit-rate adaptation is carried out by dividing the bits which are to be transferred into a number of partial bit flows with respectively separate bit rate adaptation.
