Abstract:

The present invention provides a method and apparatus for backhauling data in a communication system ( ). A plurality of quality metrics are received at a centralized controller ( ) from a plurality of base stations ( ).

International Classification:

H04Q007/20

US Classification:

455/452000, 455/450000, 455/417000

Abstract:

A wireless communication system employs a wireless network element () and at least one remote wireless unit () that employ an air interface resource reservation and negotiation scheme. In one embodiment, the remote wireless unit () includes a processing device () operatively coupled to a radio frequency transceiver (), that outputs an air interface reservation resource request (). The air interface reservation resource request () includes one or more air interface resource reservation parameters (). The air interface resource reservation parameters () are used to define a future time that is reserved by the wireless network element () for the remote wireless unit () so that suitable air interface resources are available at a defined future time. In one example, the air interface resource reservation parameters () include a position of a communication unit (), a date and time of day (), a desired bit rate for the defined future time (), desired quality of service data (), priority data associated with a plurality of air interface resource reservation parameters, and user identification data ().

Appl. No.:

13/428852

Inventors:

Michael Joseph BACH - Kildeer IL, US
Robert Stergios NIKIDES - Carol Stream IL, US

International Classification:

H04W 36/24
H04W 74/08

US Classification:

370331

Abstract:

A method includes sending a message from a first cell to a second cell comprising an instruction the second cell should enter a non-energy savings mode. The sending is responsive to a detection of one or more RF coverage problems for user equipment in a coverage area of the first cell. The second cell can provide RF coverage for part of a coverage area of the first cell. Another method includes receiving a message at a cell that is in an energy savings mode. The message includes instruction(s) the cell should activate itself and the cell is to deactivate its ability to automatically enter the energy savings mode. The second cell transitions to an active mode and deactivates its ability to automatically enter the energy savings mode. In another method, a cell makes a determination a discontinuous carrier activation mode is to be entered and enters the mode.

Appl. No.:

13/428812

Inventors:

Michael Joseph BACH - Kildeer IL, US

International Classification:

H04W 36/30

US Classification:

455525

Abstract:

A method includes determining, at a first cell and for a selected user equipment, a second cell would have a better performing RF interface connection with the selected user equipment than the selected user equipment currently has with the first cell. The first cell can provide radio frequency coverage for the second cell. The method includes sending to the second cell one or more messages indicating the second cell should not enter or be in an energy saving state at least while the selected user equipment or a selected user application on the selected user equipment is connected to the second cell. Another method includes determining a cell should not enter an energy saving state at least while a selected user equipment is connected to the cell; and the cell not entering the energy saving state at least while the selected user equipment is connected to the cell.

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.

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:

H04J 314

US Classification:

370332

Abstract:

A method for updating power control at a base transceiver station in a communication system is provided. A base transceiver station transmits a signal frame. A mobile station receives the signal frame. The mobile station determines whether the signal frame was accurately received and sets a metric bit in a quality metric. The metric bit indicates whether the signal frame was received correctly by the mobile station. The mobile station transmits the quality metric, which is received by the base transceiver station. It is then determined whether to update power control, the determination based at least in part upon the quality metric.
