Abstract:
A system and method for to establish a wireless group call from one of a plurality of communication units to others communication units includes a first step of receiving, from a requesting communication unit a request for a group call with other communication units of the group. A next step includes allocating a common downlink channel for the group call. A next step includes allocating a dedicated uplink channel for the requesting communication unit. A next step includes switching one of the communication units between the common channel mode and a dedicated channel mode depending upon performance criteria.

Abstract:
A communication device and method for controlling reverse link transmissions. The device receives a broadcast transmission signal and determines a quality level of the broadcast transmission signal. It then communicates with the base station to establish how frequently reverse link transmissions will occur depending on the determined quality level. Alternatively, a network element can determining when a parameter crosses a threshold and transmit a message to select wireless communication devices to start gating on a reverse link when the parameter crosses the threshold.
Abstract:
A method an apparatus is described for providing feedback for closed-loop transmitting with multiple transmit and receive antennas. The method includes a first step (900) of providing a codebook containing sets of weightings for each data stream of the multiple transmit antennas with each set identified by an index known to a transmitter and a receiver. The same codebook is utilized for any number of data streams up to the number of transmit antennas. A next step (902) includes measuring a composite channel between the transmitter and receiver. A next step (904) includes determining at least one performance metric for each set of weightings in the codebook. A next step (906) includes selecting preferred weightings for each data stream in response to the performance metrics. A next step (908) includes feeding back an index of the preferred weightings to the transmitter for use in subsequent transmissions.
Abstract:
A feedback method in which a notification is received that a transmitting device has scheduled a transmission of data to the receiving device. Antenna feedback is generated in response to receipt of the notification. The antenna feedback is sent to the transmitting device. A mobile device includes a wireless network interface and a processor configured to receive a notification that a transmitting device has scheduled transmission of data to the mobile device, to generate antenna feedback in response to receipt of the notification, and to send the antenna feedback over the interface to the transmitting device.
Abstract:
A method and apparatus for neighbor assisted combining for localized multicast services. Cells (112) are determined (420) in which user equipment (120) reside that desire a common multicast service. At least one serving cell for transmitting the common multicast service is selected (430) based on the determination. At least one extended serving cell is selected (440) from at least one serving cell neighbor cell (114) which wherein no user equipment reside that desire the common multicast service, transmissions on the extended serving cell influencing transmissions on the serving cell. The common multicast service is transmitted (470) on the selected at least one serving cell.
Abstract:
Sending a discovery agent to a computing device determines the services provided by that first computing device. As a result, a first set of information is received from the agent that provides information indicative of the services provided by the computing device. That information can then be compared to other information, either from the same computing device at a different point in time, or from a second computing device. The other information is indicative of services performed by that computing device at a different point in time or the second computing device. From that, services provided by the computing device that were previously different on the first computing device or that are not available on the second computing device can be determined.
