Abrégé
Binaural rendering a multi-channel audio signal into a binaural output signal (24) is described. The multi-channel audio signal comprises a stereo downmix signal (18) into which a plurality of audio signals are downmixed, and side information. Based on a first rendering prescription, a preliminary binaural signal (54) is computed from the first and second channels of the stereo downmix signal (18). A decorrelated signal (X~k) is generated as an perceptual equivalent to a mono downmix (58) of the first and second channels of the stereo downmix signal (18) being, however, decorrelated to the mono downmix (58). Depending on a second rendering prescription (P2l,m), a corrective binaural signal (64) is computed from the decorrelated signal (62) and the preliminary binaural signal (54) is mixed with the corrective binaural signal (64) to obtain the binaural output signal (24).
An apparatus for generating a binaural audio signal comprises a demultiplexer (401) and decoder (403) which receives audio data comprising an audio M-channel audio signal which is a downmix of an N-channel audio signal and spatial parameter data for upmixing the M-channel audio signal to the N-channel audio signal. A conversion processor (411) converts spatial parameters of the spatial parameter data into first binaural parameters in response to at least one binaural perceptual transfer function. A matrix processor (409) converts the M-channel audio signal into a first stereo signal in response to the first binaural parameters. A stereo filter (415, 417) generates the binaural audio signal by filtering the first stereo signal. The filter coefficients for the stereo filter are determined in response to the at least one binaural perceptual transfer function by a coefficient processor (419). The combination of parameter conversion/ processing and filtering allows a high quality binaural signal to be generated with low complexity.

Abrégé
A selected channel of a multi-channel signal which is represented by frames composed from sampling values having a high time resolution can be encoded with higher quality when a wave form parameter representation representing a wave form of an intermediate resolution representation of the selected channel is derived, the wave form parameter representation including a sequence of intermediate wave form parameters having a time resolution lower than the high time resolution of the sampling values and higher than a time resolution defined by a frame repetition rate. The wave form parameter representation with the intermediate resolution can be used to shape a reconstructed channel to retrieve a channel having a signal envelope close to that one of the selected original channel. The time scale on which the shaping is performed is shorter than the time scale of a framewise processing, thus enhancing the quality of the reconstructed channel. On the other hand, the shaping time scale is larger than the time scale of the sampling values, significantly reducing the amount of data needed by the wave form parameter representation.

A RADIO COMMUNICATION SYSTEM, METHOD OF OPERATING A COMMUNICATION SYSTEM, AND A MOBILE STATION
In a mobile communication system comprising a base station (100) and a plurality of mobile stations (200) and operating closed loop transmitter power control, power control commands for transmission on an uplink are derived from measurements made on received downlink signals comprising non~predetermined data values. Optionally the non-predetermined data values may comprise power control commands for uplink transmit power control.
This invention relates to a system and a method of generating an Authorized Domain (AD) by selecting a domain identifier, and binding at least one user (P1, P , PN1), at least one device (D1, D2, ..., DM), and at least one content item (C1, C2,..., CNZ) to the Authorized Domain (AD) given by the domain identifier (Domain ID). Hereby, a number of verified devices (D1, D2, ..., DM) and a number of verified persons (P1, P2, ..., PN1) that is authorized to access a content item of said Authorized Domain (100) is obtained. In this way, access to a content item of an authorized domain by a user operating a device is obtained either by verifying that the content item and the user is linked the same domain or by verifying that the device and the content item is linked to the same domain. Thereby, enhanced flexibility for one or more users when accessing content in an authorized domain is obtained while security of the content is still maintaining. This is further done in a simple, secure and reliable way.
In a communication system subject to variations in channel quality, transmit power control is used to reduce the variations in received signal quality. If the channel quality degrades to such an extent that a high transmit power would be required to ensure good received signal quality, the transmit power is decreased and is not increased until the channel quality recovers sufficiently to enable an acceptable transmit power level to be used. While the power is at the decreased level, transmission of a data block may continue, or may be suspended, with the data block being truncated if the whole block has not been transmitted by the end of the time period available for transmission of the data block.
A system and method is provided that resolves a possible ambiguity in WLAN measurement reports by having a measuring entity include timer values in returned measurement reports. The time a measurement was requested to be performed and the actual time it was done by a measuring entity can be compared by the receiver to ensure that no ambiguities occurred.
The present invention relates to specification of the start time for taking measurements in wireless local area networks (WLAN), in which the start time of measurements to be taken is included in a Measurement Start Time field of a Measurement Request Frame and the interpretation of the start time for a specific measured element is determined by a Mode field included in each Measurement Request Element field of the Measurement Request Frame. Optionally, the start time of a Measurement Request Frame is specified using a time synchronization function (TSF) timer value or part thereof in order to avoid ambiguities in interpretation of the start time reported.
An apparatus and method is provided for measuring medium activity patterns in wireless networks and deriving information about the radio environment from the measured medium activity/patterns. This invention is three-fold. First, it defines what to measure, including medium idle/busy patterns based on power detection, medium idle/busy pattern based on preamble detection, and medium idle/busy pattern based on virtual sensing. Second, it provides a mechanism for communicating the measurement request and report, as illustration for the case of IEEE 802.11. And last, it defines the information that can be derived given these measurements as discovery of: non-802 devices, 802.11e systems, 802.11e contention-based medium access priorities, 802.11e controlled medium access usage, 802.11b/g existence, and hidden stations.

FRAME SYNCHRONIZATION WITH ACKNOWLEDGMENT TIMEOUT IN WIRELESS NETWORKS
A wireless local area network (WLAN) includes a first device and a second device. The first device sends a first frame including a first transmission indicator, which indicates that a service interval is to begin at a certain time. The second device sends an acknowledgement from the second device to the first device indicating receipt of the first transmission indicator. The first device sends a second frame including another first transmission indicator if, after a prescribed time period, the acknowledgement is not received by the first device. The first device also sends a last transmission indicator, which indicates that the service period will end at a certain time. The WLAN and its method of use provide synchronicity between the first and second devices as to the beginning and the end of a service period.
