The method for channel and interference condition feedback Interference condition includes sending to a beamformee metric indicative of the interference level from other streams.

Systems and methods of optimizing communication channels in multi-user communication systems are provided. Coding weights are determined based on communication channel state information for communication channels between a transmitter and multiple receivers. The coding weights are applied to communication signals to be transmitted from the transmitter to the receivers. Each receiver decodes received signals using inverses of the coding weights. Embodiments of the invention support multi-user MIMO (Multiple Input Multiple Output) where each receiver has fewer antennas than the transmitter, and enhance system performance if the total number of antennas at all of the receivers exceeds the number of antennas at the transmitter.

Methods and apparatuses that generate a subtopic identifier identifying a client application within a client device that can support multiple users are described. The client application may be associated with a server application hosted in one or more application servers. Notification services may be registered with the application servers from the client application to forward identifiers associated with the client application for one of the multiple users to the server application to enable the server application to push notification messages to the client device selectively for the client application for that user. When receiving a notification message from the application server, the notification message may be examined to forward the notification message directly to the client application for that user without invoking other applications in the client device if the notification message carries a subtopic identifier of the client application.

A wireless communications system supporting multiple MIMO transmission modes supporting both diversity and directional transmissions under a plurality of different transmission modes comprises a plurality of transmit and receive antenna elements where the transmit antenna elements are arranged to provide polarization diversity. The transmitting station derives actual knowledge of the forward channel by feeding back certain information such as a preferred beam index and a channel quality indicator figure of merit for that beam from the receiving station to the transmitting station along a reverse channel. The receiving station knows the beam weights used by the transmitting station. The transmitting station applies the fed back information to transmit user data intended for the receiving station in the optimal fashion, such as along the preferred beam and at a time when forward channel conditions are satisfactory. The system provides robust single or multiple stream diversity transmission, together with the option of single user or multi-user beamforming to allow on-the-fly trade-offs between coverage gain and capacity in a wireless telecommunications system.

A multi-user file storage service and system enables each user of a user group to operate an arbitrary client node at an arbitrary geographic location to communicate with a remote file server node via a wide area network. More than one user of the user group is permitted to access the file group at the remote file server node simultaneously, but the integrity of the files is maintained by controlling access so that each access to one of the files at the remote file server is performed, if at all, on a respective portion of that file as most recently updated at the remote file server node.

A method and system for real-time multi-user interactions and collaborations over the web. A method of balancing the needs of the group and the needs of the individual is shown through implementation of relaxed WYSIWIS design principles, where each web page served by the server system is comprised of two graphical layers: a web content layer and an interaction space. The web content layer contains the textual or graphical content or the web page that may be edited by a group of users in real-time. The interaction space is where users are given virtual embodiment through graphical representations known as avatars. It is a space where users can see other users and perform actions that will be seen by others in real-time. The interaction space is overlaid on top of the web content layer thereby creating one integrated space for multi-user interaction and collaboration.
