A system and method for wireless communal gaming in a casino environment. The system includes one or more wireless gaming devices each equipped with a display, one or more gaming servers configured to communicate wirelessly with the wireless gaming devices, and one or more financial servers configured to record financial transactions for players playing communal games of chance on the handheld gaming devices. The wireless approach to communal gaming allows greater player mobility within the casino establishment and also allows a large number of players (players playing wirelessly as well as players playing traditionally at a physical player station) to participate in a common game, thereby increasing the capacity of existing communal game tables. When the wireless game-playing option is available, a player can participate in the communal game regardless of whether there is a physical player station available. Thus, flexible game-playing options can be provided to casino patrons participating in a communal game.

A system and method are provided for managing communication with a plurality of wireless client devices operating in a radio frequency band shared by other types of devices, comprising a step of controlling at least one parameter associated with radio communication with each of the plurality of wireless devices based on the radio frequency environment associated with each corresponding one of the plurality of wireless client devices. Spectrum profile information describing the radio frequency environment (activity in the frequency band) at a wireless client device is sent to the wireless base station device (where the parameter controls are made) from either a wireless client device or another radio device in the proximity of one or more wireless client devices that is capable of generating the spectrum profile information. The spectrum profile information may include information identifying signals that are occurring in the frequency band in the proximity of a wireless client device. Examples of parameters that may be controlled at the wireless base station device include packet fragmentation threshold (the length of a data packet), transmission data rate and transmission scheduling (synchronizing a transmission to quiescent intervals of one or more periodic interfering signals).

The invention provides, in some aspects, improved methods, apparatus and systems for unmanned aerial vehicle (UAV) operation that utilize multiple data links between a UAV and a control station in order to transmit control and actionable intelligence data. Such methods, apparatus and systems can be used, for example, to monitor a selected environment (e.g., an oil field or other terrain/environment of interest). In a related aspect, such data links comprise satellite communication channels.

The present invention utilizes adaptive antenna arrays at a base station to increase the forward link capacity of mobile data systems. One or more simultaneous forward link beams are formed and are switched (or hopped) in a time division manner among subscribers. The beam hopping sequence is randomized by varying the time slot and/or carrier frequency of each subscriber. In space-time hopping, the position within a frame of the time slot for each subscriber is varied in a pseudo random sequence. In space-frequency hopping, the carrier frequency for each frame is varied in a pseudo random sequence. The pseudo random beam hopping sequence provides a gain due to interference diversity in addition to the antenna array gain. Forward link beam forming algorithms use space-time or space-frequency hopping to increase the capacity of mobile data systems.

A connection is supported in a radio access network (RAN) between an external network to a UE using a first RAN node and second RAN node. The transmission rate from the first RAN node to the second RAN node is regulated based on a rate control request from the second RAN node. In one example embodiment, the first and second RAN nodes correspond to a serving radio network controller and a drift radio network controller, respectively. In another example embodiment, the first and second RAN nodes correspond to a radio network controller and radio base station, respectively. The rate control request is made based upon a congestion or load condition being monitored by the second RAN node. When the load condition is detected, the second RAN node requests the first RAN node to lower the transmission rate of information. Conversely, when the load condition is relieved, the second RAN node can request that the first RAN node increase the transmission rate of information. The rate control may be applied in both downlink and uplink directions.

It is proposed to decrease the interference in a CDMA network by automatically adapting the radiation pattern, and thereby the coverage areas, of a cell to the service coverage area without operator intervention. This will increase the overall capacity of the network, because a fully loaded cell generates less interference to neighboring cells and hence leaves more capacity in those cells. It will avoid coverage holes in case certain cells become highly loaded such that their coverage area shrinks (“cell breathing”). In an embodiment of the invention, the radiation pattern is adapted by changing the down-tilt of the antenna.

The present invention relates to a method and system for transmitting in a wireless communication system, a transmission signal divided into at least two signal parts by using transmission beams of at least two subarrays (SA1, SA2) of an antenna array. The transmission beam of at least one of the at least two subarrays (SA1, SA2) is at least in part controlled based on a feedback information received from the receiving means (20).

Thereby, the amount of feedback can be controlled so as to achieve significant feedback gain in a multi-antenna transmission even with non-maximal amounts of feedback.

In a duplex radio link wherein digital data information from a data interface is transmitted from a local terminal to a remote terminal over fading dispersive channels, a method and transceiver are described that provide for transmission at an adaptive data rate. The transmission is at a constant symbol rate so that the signal bandwidth can be fixed and at the remote terminal receiver the input sampling rate can be fixed. The digital data information is transmitted over a constant data rate interval in accordance with a selected data rate mode that is a function of direct sequence spreading gain, error correction code rate, and signal constellation type. The data rate is adapted by selecting a data rate mode that is a function of the arrival rate of data packets from the data interface and a link quality measure fed back from the remote terminal. The data packet arrival rate is controlled as a function of the link quality measure and the current data packet arrival rate. In systems with multiple transmit diversity channels, independent data is sent over each of the transmit diversity channels. The adaptive data rate technique utilizes both orthogonal transmit diversities such as frequency and troposcatter polarization diversity as well as nonorthogonal transmit diversities in a Multiple-input Multiple-Output (MIMO) configuration. A single antenna troposcatter link using angle diversity and adaptation of data rate by feedback communications is described. In an idealized feedback communication example, the single antenna system in a Ku-band application is shown to have 15.5 times the data rate capability of a conventional two-antenna system at S-band.
