Appl. No.:

09/825323

Inventors:

Donald Leimer - Rancho Palos Verdes CA, US
Charles Cahn - Manhattan Beach CA, US
Steven Chen - Cerritos CA, US

Adam Efron - Los Angeles CA, US

International Classification:

H04L012/56

US Classification:

370/390000, 370/535000

Abstract:

A wireless network of multiple base stations, each communicating with multiple remote terminals, exhibiting simpler design and enhanced inter-user and inter-base interference rejection. The downlink from a base to the multiple remote terminals employs a combination of time division multiplexing (TDM) and time division multiple access (TDMA) to multiplex signals carrying data to the remote terminals, and spreads the multiplexed signal with a pseudo-random noise (PN) sequence. The uplink from each remote terminal to the respective base uses orthogonal code division multiple access (O-CDMA) coding to multiplex a variable number of channels for each remote terminal. Short O-code sequences are derived based on pseudo-random maximal length sequences and quadratic residue sequences to introduce sufficient randomness into the multiple access coding to reject inter-base interference without the use of PN signal spectrum spreading.

Inventors:

- Menlo Park CA, US
Praveen Kumar Gopala - Sunnyvale CA, US
Adam Joshua Efron - Irvine CA, US

International Classification:

H04L 12/24

Abstract:

Apparatuses, methods, and systems for dynamic bandwidth allocation are disclosed. One method includes identifying, by a first distribution node of a wireless mesh network, a communication link with a second distribution node of the wireless mesh network, generating, by the first distribution node, a proposed bandwidth allocation schedule for wireless communication of information between the first distribution node and the second distribution node, wherein the second distribution node receives the proposed bandwidth allocation schedule, and wherein the second distribution node adjusts the proposed bandwidth allocation schedule. The method further includes receiving, by the first distribution node, the adjusted proposed bandwidth allocation schedule from the second distribution node, and communicating, by the first distribution node, information with the second distribution node according to the adjusted proposed bandwidth allocation schedule.

Abstract:

One method includes identifying, by a first distribution node of a wireless mesh network, a communication link with a second distribution node of the wireless mesh network, generating, by the first distribution node, a proposed bandwidth allocation schedule for wireless communication of information between the first distribution node and the second distribution node based on data traffic requirements of the first distribution node, wherein the second distribution node receives the proposed bandwidth allocation schedule, and wherein the second distribution node adjusts the proposed bandwidth allocation schedule based upon data traffic requirements of the second distribution node. The method further includes receiving, by the first distribution node, the adjusted proposed bandwidth allocation schedule from the second distribution node, and communicating, by the first distribution node, information with the second distribution node according to the adjusted proposed bandwidth allocation schedule.
