摘要:
An interface, apparatus, and method are described for communication between a radio control (REC) node and first and second radio equipment (RE) nodes in a radio base station that transceives information over radio interface using multiple antenna carriers. The REC node is separate from and coupled to the first RE node by a first transmission link, and the second RE node coupled to the first RE by a second transmission link. Both control information and user information intended for communication between the REC node and the first RE node and the REC and the second RE node are conveyed over the first transmission link. The first RE node also conveys information between the REC and second RE node. Many advantageous features are described.

摘要:
A radio terminal is organized to send a first access signal then, when it receives a positive acknowledgement from a base station, a second access signal, resources of the communication network being allocated to the radio terminal after receipt of the said second access signal at the base station. At a base station, the first access signal sent by a radio terminal is received and the communication service requested by the terminal is detected therein. In conditional manner, depending on the detected communication service, a receive power of the first access signal is measured, the measured receive power is compared with a threshold, and the transmission of a positive acknowledgement of the first access signal to the radio terminal is inhibited, when the measured receive power is greater than the said threshold.

In order to acquire first subbands in at least a central band of a broad frequency band, in which subbands frames are transmitted by a base station (BSBB) of a broadband network (RBB) which is co-located with a network (RNB) having narrow subbands comprised in the broadband, a mobile (MBBB) which does not know the distribution of the subbands correlates subsequences of a generated reference signal with subsequences which are respectively detected in the subbands and compares correlation coefficients against a threshold. By knowing the distribution of the first subbands, the mobile is able to process the signalling transmitted by the base station, in order to access allocated resources, after a synchronisation phase.

A transmission signal (S) resulting from modulation of a digital data signal by a modulation function dependent on time t, the data signal being formed of a series of bits (bk) each identified by its rank k and having a duration T, the transmission signal (S) consisting of a summation indexed to the rank k of the product of the complex constant j to the power k, of the modulation function (h(t−kT) and of an input signal. The input signal F(k) being a function of the data signal (bk), the modulation function h(t−kT) is a Gaussian function of time t.
摘要:
In certain circumstances, a mobile radiocommunication terminal estimates an initial radio signal transmission power, i.e. a random access request, to a base station located within the range thereof. If it is very close to said station, said initial estimated power can be lower, even greatly lower, than the minimum transmission power of the mobile terminal. In order to limit interference with other communications in progress, the transmission of said signals is inhibited if the difference between the minimum transmission power and the initial estimated power lies beyond a predefined threshold.

The present invention relates to a method for enabling radioelectric coexistence between two devices based on personal mobile radio or PMR technology, of which one is a narrow band device and the other is a broadband device, and each device interacts via a radioelectric link with respective base stations connected to a control unit for the radio resource of their respective networks, characterized in that it comprises the following steps: detection of the presence of a narrow band radioelectric emitter device in the vicinity of device, transmission of a message on the broadband network, addressed to the control unit, which message signals the presence of a possible narrow band emitter close to said device, and assignment by the control unit of new frequency blocks for uplinks, only in predefined allocated periods.
