摘要:
Apparatuses and methods for transmitting control data on a physical channel between a mobile radio device and a base station in a cellular network. In particular, in a mobile radio network according to the UMTS standard (UMTS=Universal Mobile Telecommunication System) a packet-oriented data transmission between the mobile radio device and the base station is controlled using control data, wherein the control data includes a packet number for identifying a data packet.

A method is provided for rate matching a number of input bits in a time interval to a fixed number of output bits in the time interval, whereby the input bits consist of a set of at least two different bit classes, each of the classes having a certain number of bits in the time interval, whereby the rate matching is performed in two rate matching stages, whereby the first rate matching stage operates only on a selection out of the set of different bit classes, thus establishing a proportion between the number of bits of the different classes, and the second rate matching stage operates on all bit classes such that the proportion is exactly or approximately maintained after the second rate matching stage and the fixed number of output bits consisting of bits of the different bit classes is achieved.
摘要:
A method for transmitting data via a data transmission channel in a communication network. The transmission channel is made available for the wireless transmission between a transmitter and a receiver. The data transmission is carried out while taking into consideration the channel quality in such a manner that the channel quality data available during transmission is as current as possible and no unnecessary transmission of channel quality data is required.

A method combining data packets by a telecommunication device, whereby a first data packet comprising a first retransmission number being received by the telecommunication device on a telecommunication channel, the next data packet being received by the telecommunication device on the telecommunication channel is a second data packet comprising a second retransmission number at a delay time dt after the first data packet, whereby the delay time is determined by a number of retransmission time steps and the first and the second retransmission number is smaller than or equal to a maximum retransmission number, whereas in the case of the second retransmission number being smaller than the maximum retransmission number, the first and the second data packet are combined to a resulting data packet if the difference between the second and the first retransmission number is equal to the number of retransmission time steps.

In a method for communication by radio afrequency band that is subdivided into a plurality of subbands is used. Subbands are occupied by radio stations for sending signals. Before sending a signal, a radio station carries out a filtering operation by using a filter function and sends the signal on at least one subband. A parameter of the filter function depends on the occupation of at least one subband adjacent to the at least one subband.

A method transmits data between a base station and a terminal in a communication system. According to said method, data is transmitted subdivided into time segments (Zs,R) from the base station (HS-DSCH) that is jointly used bye several terminals via the base station informs the terminals, and the base station informs the terminal via one of at least two control channels method encompasses the following: the at least two control channels (HS-SCCH1, HS-SCCH2) are monitored by the terminal; the terminal receives the piece of control information on a first of the at least two control channels (HS-SCCH1) within a first time segment (ZS1, R1); an individual decision parameter is generated for each of the parts (P1, P2) of control information based on the content of the respective part (P1, P2) of control information: an overall decision parameter is determined based on the individual decision parameters; data received on the data channel (HS-DSCH) and the piece of information received on the control channel (HS-SCCH1) are rejected in accordance with the overall decision parameter.
摘要:
A method for receiving or transmitting messages wherein the use of shortened spreading codes, especially in the paging channel, for the purpose of correlation in the reception of CDMA signals, provides for power-saving measures such as, for example, the intermittent turn-off of A/D converters or correlators and to preserve the orthogonality of the spreading codes, the spreading codes used are selected in such a manner that, if possible, they do not correlate with the paging channel spreading code.
摘要:
A decoding method for decoding information content in at least one data packet, which is transmitted from a sender to a receiver via a data link. The information is represented by a bit sequence, which is transformed into a transmittable redundancy version. The information is initially transmitted for a first time in a first data packet from the sender to the receiver. The information is represented by a first redundancy version, which is self-decodable. An incorrect receipt is confirmed by sending a confirmation from the receiver to the sender. The information is retransmitted at least a second time in a second data packet from the sender to the receiver upon receipt of the confirmation, wherein, for representation of the information, a second redundancy version is used, the selection of which is performed in dependence on a coding parameter, describing whether the redundancy version is self-decodable or not.

A code sequence is described by a line of a code matrix, the latter being obtained by formation of a Hadamard matrix with a length n and multiplication of lines of the Hadamard matrix by −1.
