US Patent:

7085574, Aug 1, 2006

Filed:

Aug 1, 2003

Appl. No.:

10/633013

Inventors:

Peter Gaal - San Diego CA, US
Boris S. Tsybakov - San Diego CA, US

Assignee:

QUALCOMM, Incorporated - San Diego CA

International Classification:

H04Q 7/20

US Classification:

4554521, 455450, 455561, 370445, 370431

Abstract:

Methods and apparatus for scheduling grant channels to carry grant messages to a plurality of scheduled mobile stations. The scheduling of grant channels involves dynamically assigning to a current mobile station of the plurality of scheduled mobile stations, a previously unassigned grant channel from a list of grant channels monitored by the current mobile station. If there are more mobile stations to be processed in the plurality of scheduled mobile stations, then the scheduling moves to a next mobile station in the plurality of scheduled mobile stations, and the assignment process is repeated. Furthermore, if not every grant channel has been assigned a mobile station, then the order of the plurality of scheduled mobile stations is rearranged, and the assignment and the movement processes are repeated.

Appl. No.:

11/875634

Inventors:

Boris Tsybakov - San Diego CA, US
Edward Tiedemann, Jr. - Concord MA, US
Peter Gaal - San Diego CA, US

Assignee:

QUALCOMM Incorporated - San Diego CA

International Classification:

H04B 7/216

US Classification:

370441, 370329

Abstract:

Systems and techniques are disclosed relating to communications. The systems and techniques involve dividing a plurality of subscriber stations into a plurality of groups, assigning a different plurality of orthogonal codes to each of the groups, the number of the orthogonal codes assigned to one of the groups being less than the number of subscriber stations in said one of the groups, encoding communications to one of the subscriber stations in said one of the groups at a data rate, and determining whether to spread at least a portion of communications to said to one of the subscriber stations with one of the orthogonal codes assigned to said one of the groups as a function of the data rate.

US Classification:

370/329000, 370/431000

Abstract:

In a communication system () for communication of data, a method and apparatus provide for detecting a request for opening a connection for a user () for communication of data, selecting an open connection, releasing the selected open connection, and allocating, to the user (), communication resources corresponding to resources released based on releasing the selected open connection. In accordance with an embodiment, the selected open connection is in an idle open state.
