A method of transferring information signals between two separate send/receive interfaces which are part of the same communication device includes processing of the signals. The two interfaces use, at least for information data useful to users, referred to as user data, similar transmission structures and protocols, and in particular similar formats and apply opposite processing sequences for a particular incoming signal. One of the interfaces converts modulated data into baseband data and the other of the interfaces converts the baseband data into modulated data, or vice-versa. The method distinguishes between user data and signaling data, applies all processing operations to the signaling data to enable it to be interpreted by each of the interfaces, and applies to the user data only processing operations needed to transfer it from a first of the interfaces to the other of the interfaces without reproducing or reconstituting or interpreting its content.

Method of transferring signals between two separate send/receive interfaces, the method including processing of the signals

A method is disclosed of synchronizing the operation of two or more interfaces sharing shared communication means or a shared communication resource. The periods of operation of the interfaces, and in particular the periods of use of the shared communication means or the shared communication resource, do not overlap.

Synchronized contention resolution and burst timing allocation in the operation of two or more interfaces

Wireless telecommunications systems with at least one base station and with mobile user terminals are known where radio signals are transmitted and received in different time and frequency states. Both on user channels as well as on signaling channels there are radio signals that are transmitted corresponding to the predicted frequency hopping sequence. We now suggest, first, that the base station and the user terminal contain controllers (CTR) to control the frequency state alternation that produce no frequency hopping sequences for the first part of the time grid but rather predict a steady frequency (f ) and produce a pseudorandom frequency hopping sequence (THS) for at least one further part of the time grid after one iterative process (LGNR), second, that the base station transmits an input value (CW) to the user terminals in order to process the pseudorandom frequency hopping sequence, and to control the frequency alternation in accordance with this pseudorandom frequency hopping sequence in the controller for registering user terminals. This way we can achieve the result that a processed frequency hopping sequence is used as early as during transmission of registration signals, i.e. a frequency hopping sequence that is developed on the basis of the input value and does not have to be saved completely.
