摘要:
The present invention concerns a method for determining if an information word transferred by a source has to be relayed by a telecommunication device. The signals transferred by the source are composed of complex symbols obtained from the information word. The telecommunication device: receives at least one signal composed of complex symbols transferred by at least the source, successfully decodes the information word from the at least one received signal composed of complex symbols, checks if the successful decoding is performed prior to an expected successful decoding time of the information word, the expected successful decoding time being obtained from prior successful decoding of other information words, and if the successful decoding is performed prior to the expected successful decoding time of the information word: obtains at least one signal composed of complex symbols obtained from the information word, transfers the at least one obtained signal.

The present invention concerns a method for transferring information enabling the adjustment of the transmission power of the signals transferred and/or received by a first base station through a wireless interface, a cell of the first base station being at least partly comprised in a cell of a second base station. A mobile terminal for which a handover has been or has to be conducted between the first and second base stations obtains information related to the path between the second base station and the mobile terminal and transfers information to the first base station.

The present invention concerns a method for enabling, in a wireless cellular telecommunication network, at least one mobile terminal served by a telecommunication device to transfer and/or receive data through multiple frequency bands. The telecommunication device: obtains at least one mobile terminal carrier aggregation capability of the at least one mobile terminal, determines a coordinated carrier aggregation capability C of the telecommunication device, transfers the coordinated carrier aggregation capability C to a centralizing device, transfers information related to at least one neighbouring telecommunication device to the centralizing device, receives, from the centralizing device, information indicating at least one frequency band the telecommunication device has to use for communicating with the mobile terminal, transfers control signalling to the at least one telecommunication device through the at least one frequency band the telecommunication device has to use.
摘要:
The present invention concerns a system for transmitting information data from a transmitter to a receiver over nested block channel, the transmitter (TRD) comprising an encoder (ENC) following an error correcting code structure, the receiver (RCV) comprising a decoder (DEC) defined according to the error correcting code structure, the nested block channel (NBCH) comprising a scaled BPSK binary modulator (BM), the amplitude of which may vary from one bit transmission to the other. Such system is characterized in that the coding rate (Rc) of the encoder (ENC) or the parameters (D,L) of the nested block channel (NBCH) are selected dependently one from each other to achieve a target diversity order of the system and to maximize the coding gain.
摘要:
A method enabling a mobile terminal to access a wireless cellular telecommunication network including plural base stations and a core network device. The mobile terminal is allowed to access the wireless cellular telecommunication network through at least one first base station and memorizes a list including information enabling the identification of signals transferred by each first base station, the mobile terminal not memorizing information enabling the identification of signals transferred by second base stations. One second base station: receives a message requesting the second base station to transfer signals that should be transferred by one first base station, transfers signals that should be transferred by the first base station, and broadcasts information enabling the identification by the mobile terminal of other signals transferred by the second base station and/or at least one other second base station.
摘要:
The present invention relates to a method for transmitting data between a transmitter provided with at least two transmitting antennas (ta1, ta2 . . . taNt) and a receiver. The method according to the invention further includes a symbol spreading step in the course of which components Zij (for i=I to S and j=I to Nt) of a predetermined number of successive symbols ZI . . . ZS are to be spread over time before being transmitted over said transmitting antennas (ta1, ta2 . . . taNt). The data transmitted at any given moment will thus not be representative of a single symbol Zi (for i=1 to S), as is the case in known MIMO systems, but will represent a mixture between Nt components of S successive symbols, which introduces data diversity with respect to time as perceived at the receiver end.

“Method for transmitting uniformly distributed data in a MIMO telecommunication system”The present invention relates to a method for transmitting data by means of Nt transmitting antennas over comunication channels featuring Ni inputs. The method according to the invention includes a bit interleaving step involving: bit demultiplexing DMXS, sequence interleaving SRIS, sequence storing and segmenting, segment permutation SPS, and sequence allocation ALS for forming groups G1, G2 of Nt permutated bit sequences Psqj intended to be transmitted through Nt channels allocated to a same bit rank for all transmitting antennas. The invention ensures an essentially homogeneous distribution of the encoded data bits over the different channel inputs, and thus favours data diversity.

A method for enabling a mobile terminal to access to a wireless cellular telecommunication network including plural base stations, the mobile terminal having right to access to the wireless cellular telecommunication network through a first base station, the mobile terminal having no right to access to the wireless cellular telecommunication network through a second base station. The method includes: detecting reception of a message transferred by the mobile terminal to the second base station, determining if the first base station is operational, giving right to the mobile terminal to access to the wireless cellular telecommunication network through the second base station if the first base station is not operational, and rejecting right to the mobile terminal to access to the wireless cellular telecommunication network through the second base station if the first base station is operational.

A method for allocating, by a telecommunication device, at least first and second channel elements of a group of channel elements of a channel resource to a destination. The telecommunication device: selects, for the first channel element, a first randomization function according to the position of the first channel element within the group of channel elements and according to the destination; selects, for the second channel element, a second randomization function according to the position of the second channel element within the group of channel elements and according to the destination; processes the data to be included in the first channel element by the first randomization function and processes the data to be included in the first channel element by the second randomization function; and transfers the processed data.
