US Patent:

54756863, Dec 12, 1995

Filed:

Dec 28, 1992

Appl. No.:

7/997997

Inventors:

Michael J. Bach - Niles IL
William R. Bayer - Palatine IL

Assignee:

Motorola, Inc. - Schaumburg IL

International Classification:

H04J 322

US Classification:

370 84

Abstract:

A communication system (101) concentrates the output of variable rate transcoders (XCDRs 203, 206, 209) to realize an increase in T1 Megastream link capacity. Line interface cards (212, 213) multiplex a generic transcoder/rate adapter unit (GTRAU) format to a concentrated transcoder/rate adapter unit (CTRAU) format based on a determined rate of the data being output from the variable rate transcoders (XCDRs 203, 206, 209). An increase in T1 Megastream link capacity is realized by efficiently concentrating full, half, quarter, and eighth rate channels into a single DS0 for transmission over the T1 Megastream.

Appl. No.:

8/190433

Inventors:

T. Michael Schaffner - Palatine IL
William R. Bayer - Palatine IL
Michael J. Bach - Niles IL

Assignee:

Motorola, Inc. - Schaumburg IL

International Classification:

H04B 169
H04B 1707
H04J 1302
H04J 1304

US Classification:

375200

Abstract:

A differential coherent modulation and demodulation method and apparatus non-coherently modulates (201) a data stream to generate non-coherently modulated data. The non-coherently modulated data is phase modulated (215) with a supplementary signal (211) to generate coded data. The coded data is then transmitted. A receiver (301) then receives the coded data. A non-coherent demodulator accepts the received coded data as input and demodulates the coded data to provide the original data and the supplementary signal (327).

International Classification:

H04W 64/00
H04W 48/20

Abstract:

A network access node (eNodeB for example) changing status from active to deactivated sends a message to a location server indicating the changed status. The location server collects from uplink messages indications of which of a plurality of cells have a deactivated status and stores this information in its local memory. Then the location server utilizes the stored indications to ensure that all cells in a list provided to a user equipment for location assistance will have an active status. In various embodiments: the message is sent only when the status is changed for energy saving purposes; a list of cells included in a location request message may have some deactivated cells so the location server sends a message to the eNodeB to activate deactivated cells in the list which is done prior to providing the list to a user equipment; and a partial-activation for a probing/beacon mode is disclosed.
