Abstract: A method and apparatus for controlling the transmit power of a mobile device in a mobile communication network takes the level of self-interference into account to perform inner-loop power control. For normal inner-loop power control, a signal quality estimate is compared to a signal quality target and power control commands are generated based on the comparison. When self-interference is the dominant impairment in the received signal, a “fast break” is introduced to change inner-loop power control command generation. The amount of self-interference is determined based on the delay spread of the channel.

Abstract: A hybrid channel estimator for a wireless communication system receiver includes both correlation based and least squares based channel estimators. The correlation estimator is used when signal quality is low or noise is colored. The least squares estimator is used when signal quality is high or noise is white. An interference suppression filter improves signal quality by suppressing interference in a received signal. Generally, correlation channel estimation is performed initially, when signal quality is low and noise is colored, and interference suppression filtering is performed to increase signal quality by removing certain portion of interference and whitening the overall impairment spectrum. These may be done iteratively. When the signal quality improves, least squares channel estimation is performed, which may also be iterative.

The process includes the steps of: (a) obtaining a set of data points representing estimates of a given parameter; (b) using a computer to process said data points with an unsupervised clustering algorithm to select data points for use in making a preferred estimate of the given parameter; and (c) using the selected data points to make a preferred estimate of the given parameter.

Abstract: By transmitting the Measurement cell identity (MCI), in addition to the PCI PLMN cell identity (PCI), in a request to a node, an MCI to PCI mismatch is early discovered by the node and reported to the source eNode B. The handover procedure can be aborted in an earlier stage, saving time and resources. The node can then also include information in the response to the source eNode B, which makes it possible for the source eNode B to blacklist MCIs and MCI to PCI combinations. This way faulty or faked MCIs or PCIs can be discovered already in the source eNode B, saving even more time and resources.

Abstract: The present invention involves establishing a top-level key and optionally also a verification tag. The top-level key is used as the MDP key for encrypting a broadcast medium. Only the part of the key message that contains the encrypted top-level key is authenticated, e.g. using a signature or a Message Access Code (MAC). Any known group-key distribution protocol can be used that is based on the creation of a hierarchy of keys. Examples of such methods are the LKH and SD methods. The group-key distribution protocol output key H, traditionally used as the MDP key, or a derivative thereof is used to encrypt the top-level MDP-key. The invention, further, includes optimization of a group-key message by eliminating unnecessary message components relative a specified group or sub-group of users. The optimization can be made in dependence of contextual data such as user profile, network status, or operator policies.
