An apparatus, method and computer program is described. The method can include receiving a first measurement report from a first communication node of a mobile communication system. The first measurement report can include downlink measurement data generated at a user device in response to a positioning reference signal sent by the first communication node. The method can further include receiving a second measurement report from the first communication node. The second measurement report can include uplink measurement data generated at the first communication node in response to an uplink reference signal sent by the user device. The method can also include determining an integrity of the measurement data based on a comparison of said uplink and downlink measurement data and setting an integrity verification notification in accordance with the determined integrity.

Embodiments of the claimed subject matter provide a method and apparatus for virtual sectorization using an active antenna array. Embodiments of the apparatus include a transmitter for providing signals to an active antenna array. The signals cause the active antenna array to transmit a first reference signal to a first sector indicated to user equipment within the first sector by a sector identifier. The signals also cause the active antenna array to transmit a plurality of second reference signals into a corresponding plurality of second virtual sectors that overlap the first sector. The apparatus also includes a scheduler for scheduling transmission to user equipment based on feedback generated by the user equipment using the first reference signal or the second reference signals.

Method and system for enhancing channel capacity in a Point-to Multipoint radio communications system that includes terminal stations () of different kinds, such as residential terminals and business terminals, with different link budget requirements i.e. different signal-to-noise ratio. The method is characterized by the selective use of different channel coding codes such as forward error correction (FEC) codes, in the different concurrent channels, depending on a pre-defined category of an addressed subscriber. The multiplexing method used may be CDMA (Code Division Multiple Access) and TDMA (Time Division Multiple Access). Each terminal station () is in turn equipped only with an appropriate decoder, depending on its kind, e.g. residential or business.

The invention relates to an asynchronous transfer mode method of transmitting digital signals in which terminals () send to the same station (). Calls are transmitted by cells (), the terminals send successively in separate periods (), and each cell is assigned at least two orthogonal codes (C, C, C, C). In accordance with the invention, the duration of the period during which each terminal sends and/or the number of codes assigned to each terminal and/or the number of symbols assigned to a particular code in a terminal can be selected on each sending as a function of a particular power level ().

The invention concerns a method of transmitting non-dated digital data between a transmitter and a receiver in which the data can take at least two different paths between the transmitter and the receiver and handover from one path to another occurs during transmission. In the transmitter, packets intended for the second path are transmitted only after the last packet intended for the first path has been transmitted and in the transmitter and in the receiver packets on the first or second path are delayed in order for packets on the second path to arrive after packets on the first path. It is therefore not necessary to transmit signaling to differentiate the two paths at the receiver, which can include a single demodulator.

The invention relates to apparatus for filtering, decimating and transposing into baseband, the apparatus being of the entirely digital type, and serving both to extract and transpose into baseband one of the channels, referred to as the &ldquo;channel of interest&rdquo;, of a frequency multiplex of channels, and also to reduce the oversampling factor of said channel of interest, each channel being associated with a distinct carrier. The said apparatus comprising at least two stages in cascade ( to ), each stage comprising filter means ( ) and decimation means ( ), said filter means being placed upstream from said decimation means and enabling a portion of the spectrum to be purged at locations where the decimation means produce aliasing. According to the invention, each stage ( to ) also comprises transposition means ( ) placed upstream from said filter means ( ) and associated with a transposition frequency (f ) previously selected from a set of N possible distinct transposition frequencies so as to transpose the carrier (p ) associated with said channel of interest as close as possible to zero frequency.

A device for receiving a source digital signal transmitted at one or more source symbol frequencies F.sub.s samples a received analog signal transposed into the baseband and delivers an entirely demodulated sample signal. The sampling frequency F.sub.e complies with the generalized sampling condition. A single filter module filtering the sampled signal comprises a digital filter controlled by a filter coefficient vector. The filter coefficients are determined according to a determination criterion allowing for the ratio of the sampling frequency F.sub.e to the source frequency F.sub.s, to interpolate the sampled signal, and for an analysis of the transmission path, in order to limit interference introduced by the path.

A method of modeling the AM--AM and AM-PM characteristics of an amplifier includes the step of transmitting a reference signal to the amplifier. The response of the amplifier to the reference signal is digitized to produce two sets of AM--AM and AM-PM reference samples, respectively. Two series of polynomials respectively representative of the AM--AM and the AM-PM characteristics are determined from the samples. The determination of each polynomial allows for the second derivative of the polynomial and for the distances between the samples and points on the curve defined by the polynomial.
