Abstract: An access point (100) transmits at least a first set of parameters intended for a first set of users (102) and a second set of parameters intended for a second set of users (104). The access point communicates with the first set of users during a first time period and communicates with the second set of users during a second time period, wherein the first time period and the second time period are exclusive of each other. Moreover, the first time period and the second time period lapse prior to the AP transmitting a next set of parameters intended for the first set of users.

Abstract: A method of registration in a communication system includes the steps of detecting (201) an elevated registration level of at least a part of a communication system, selecting (203) a group recovery time, determining (205) a first random registration time that is less than or equal to the group recovery time, registering (209) a first communication unit (111) from a first talkgroup at the first random registration time, and upon receiving (212) a group activity message for the first talkgroup, delaying (213) registration by at least a second communication unit (113) from the first talkgroup.

Abstract: A method for communicating beacon transmissions from a wireless access point (WAP) to a client transceiver in a wireless local area network (WLAN) system (figure 1) includes obtaining a reference timing for the wireless access point. The sector configuration and the sector timing in the WAP is then determined. A virtual target beacon transmission time (TBTT) for the sector of interest serviced by the WAP is then calculated, as is a channel number of the sector of interest Finally, the method provides for listening for a sector beacon signal from the sector of interest at the virtual TBTT and the calculated channel number.

Abstract: A communications system and method for exchanging spectrum usage information through a drop box (100) includes one or more central stations (101) that defines a region of operation. A central drop box (102) is associated with the central station (101) for providing a database of spectrum usage information. Stations (103, 105, 107) using the communications system may submit information regarding spectrum usage to the central drop box (102) that affects the region of operation (109, 115) for providing the most efficient and non-interfering uses of the frequency spectrum.

Abstract: A self-learning geographically aware handoff method and system is disclosed. The system includes a handoff manager (108), which receives information about a position and movement of the mobile nodes (102a, 102b, 102c and 102d) present in the mobile network (100). The handoff manager learns the coverage capabilities of the access points (104a, 104b, 104c and 104d) in the mobile network. It then determines a second access point, to which a mobile node will handoff to, based on the learned coverage capabilities. The handoff manager then informs the mobile node about the second access point.

Abstract: Methods for performing client to client communication in a wireless local ar ea network are disclosed. At an 'n' tier client in the wireless local area network, a signaling message from an 'n-1' tier client is received wherein t he signaling message comprises a first period, a second period, and a third period. Communicating with the 'n-1' tier client during the first period and communicating with the 'n+1' tier client during the third period. At an acce ss point in the wireless local area network, an association table identifying clients in the wireless local area network is created and a first period for client to client communication based upon the association table and traffic in the wireless local area network is determined where the access point does no t communicate with the clients during the first period.

Abstract: A first device (102/104) receives a first message (300) from a second device (104/102) over a communication link (106). The first device also receives a first transmit power level (202/212) by which the first message was transmitted and a first interference level (204/208) as perceived by the second device. The first device calculates at least one transmission parameter by which a second message will be transmitted to the second device based on the first transmit power level and the first interference level.

Abstract: At a first device (102 or 104), a message is received and processed. If the message is processed during a first time period, the first device transmits an acknowledgement message during a second time period; otherwise the first device transmits the acknowledgment message during a third time period. The second time period and the third time period are exclusive of each other.

Abstract: A communication band is divided into a plurality of allocation channels ( 202, 204, 206, 208 ). At least one allocation channel ( 204 ) is transferred to a transform domain. The behavior of the at least one allocation channel is monitored in the transform domain in order to derive a set of statistics. The set of statistics are used to determine a channel category for the at least one allocation channel.
