摘要： A method for transmitting data by a device having a cell, called a second cell, conforming to a first protocol of a cellular access network and capable of transmitting in a frequency band shared with a network conforming to a second protocol and capable of implementing a listening-before-transmission (LBT) access mechanism. The method includes: using the LBT access mechanism by a first cell, and transmitting by the first cell an identification of a first sharing group, first channel sharing information and a transmission duration; using the LBT access mechanism with adaptation by the second cell to determine an interfering power separately from a received power of a transmission from the first cell; and enabling channel sharing with the first cell if the second cell belongs to the same first sharing group, the first channel sharing information authorizes the sharing and the interfering power does not exceed a given threshold.

摘要： An Integrated Access and Backhaul (JAB) node incorporates two functions, a so-called “base station” function and a so-called “mobile terminal” function. In order to limit the interferences between base stations, all IAB nodes in the same network must be synchronised with one another. In order to ensure this synchronisation, each IAB node may use a time shift value transmitted by its parent node. However, since an IAB architecture is an arborescent architecture, errors in measuring an estimated time shift value for a given IAB node have repercussions on the measurements of estimated time shift values for its child node and so on. Accordingly, the “base station” function of a child IAB node is not activated as long as a time shift value determined by its parent node does not meet a synchronisation criterion.

摘要： A method for transmitting a multi-carrier signal implementing an OQAM-type modulation, formed of a temporal succession of symbols including data elements modulating a carrier frequency of the signal. A carrier frequency modulated by one of the data elements is called a carrier, wherein a set of carriers is allocated to a transmitter unit. The method includes inserting a sequence of pilots specific to the transmitter unit at a given time into the multi-carrier signal on the allocated set of carriers. The sequence of pilots includes: a sequence of non-zero complex values, inserted on odd or even carriers, alternating with zero values, inserted on the other carriers, respectively even or odd-numbered; non-zero complex values of the sequence of pilots, their frequency transforms and inverse frequency transforms being with a constant envelope; and and a sequence of zero values modulating the carriers of the set of carriers allocated at the following time.

摘要： A method implementing the same frequency-time transform of size M irrespective of the service. The method adds, during a frame setup, a cyclic extension of L=L1+L2 samples in order to obtain a sequence of M+L samples. The method carries out a time-domain filtering according to a function ƒ(n) of the samples n of the sequence of M+L samples.

摘要： A method for handover between base stations of an access system for access to a core network including interconnections in a tree structure having wireless links and a single wired link. The wired link connects only one of the base stations, known as a donor node, to the core network. The interconnections between the base stations are solely wireless links. The method includes: transmitting, by a source base station of the access system, to which a terminal is attached, a handover request to a target base station of the access system, the source and target base stations being interconnected via at least one base station known as a decision-making node, which is different from the donor node; intercepting the handover request by the decision-making node; transmitting, by the decision-making node, an agreement message to the source base station; and transmitting a handover trigger message to the target base station.

摘要： A method is provided for modulating data symbols, outputting a multi-carrier signal, implementing: a mathematical transform, which transforms data symbols from the frequency domain to a time domain, outputting transformed symbols; and a polyphase filtering, which filters the transformed symbols, outputting the multi-carrier signal. The polyphase filtering uses an expansion factor taking account of a compression factor t, the compression factor τ being a number between 0 and 1 such that the multi-carrier signal can be transmitted at a Faster-Than-Nyquist rate.

摘要： Integrated Access and Backhaul (IAB) nodes communicate with one another in half-duplex mode. Such a multiplexing of the communications of the IAB node requires simultaneous execution of a “mobile terminal” function and of a “base station” function by the IAB node. However, these two functions are not synchronised with one another, resulting in a lack of temporal alignment between the data communicated with the parent node and the data communicated with the child node, which causes interference that negatively impacts the quality of the communications between the different IAB nodes involved. Existing solutions suffer from long data processing times and are expensive. Accordingly, a time offset is introduced during the processing of the data by the child node, in order to take into account the lack of synchronisation between the “mobile terminal” function and the “base station” function of the current node.
