Transmission format in packet based communications

Claim 2

A packet based communications method for communicating between at least one base station and a plurality of users, comprising: using a transmission frame to carry formatted, time-sequenced messages, the transmission frame comprising (i) a frame marker field which delimits the transmission frame, (ii) a signaling field which comprises communications system information, and (iii) a communication field which comprises user-provided/destined information, the frame marker field, signaling field and communication field being in a predetermined order and each one of the fields having a predetermined length; and transmitting the transmission frame carrying the formatted messages over at least one communications channel between users and the at least one base station.

Claim 3

The method of claim 1, comprising periodic broadcasting by the at least one base station, of a frame marker signal in the frame marker field.

Claim 4

The method of claim 1, wherein formatting comprises including polling information in the communication field.

Claim 5

The method of claim 1, wherein formatting comprises including base-to-user broadcast information and user-to-base random-access information in the signaling field.

Claim 6

The method of claim 4, wherein including broadcast information comprises including base station identifying information.

Claim 7

The method of claim 4, wherein including broadcast information comprises including connection tree identifying information.

Claim 8

The method of claim 4, wherein including broadcast information comprises including pilot tones for elements of an array antenna.

Claim 9

The method of claim 4, wherein including broadcast information comprises including pilot signals for a transversal equalizer.

Claim 10

The method of claim 4, wherein including broadcast information comprises including a paging signal.

Claim 11

The method of claim 4, wherein including random-access information comprises including a handoff request signal.

Claim 12

The method of claim 4, wherein including random-access information comprises including connection tree request information.

Claim 13

A packet based communications system for communicating between at least one base station and a plurality of users, comprising: formatting means for formatting messages according to a transmission frame comprising (i) a frame marker field which delimits the transmission frame, (ii) a signaling field which comprises communications system information, and (iii) a communication field which comprises user-provided/destined information, the frame marker field, signaling field and communication field being in a predetermined order and each one of the fields having a predetermined length; and transmission means for transmitting the transmission frame carrying the formatted messages over at least one communications channel between users and the at least one base station.

Claim 14

A packet based communications system for communicating between at least one base station and a plurality of users, comprising: formatting means for formatting messages according to a transmission frame comprising (i) a frame marker field which delimits the transmission frame, (ii) a signaling field which comprises communications system information, and (iii) a communication field which comprises user-provided/destined information, the frame marker field, signaling field and communication field being in a predetermined order and each one of the fields having a predetermined length; and transmission means for transmitting the transmission frame carrying the formatted messages over at least one communications channel between users and the at least one base station.

Claim 15

The system of claim 12, wherein the at least one base station comprises means for periodically broadcasting a frame marker signal in the frame marker field.

Claim 16

The system of claim 12, wherein the formatting means comprises means for including polling information in the communication field.

Claim 17

The system of claim 12, wherein the formatting means comprises means for including base-to-user broadcast information and means for including user-to-base random-access information in the signaling field.

Claim 18

The system of claim 15, wherein the means for including base-to-user broadcast information comprises means for including base station identifying information.

Claim 19

The system of claim 15, wherein the means for including base-to-user broadcast information comprises means for including connection tree identifying information.

Claim 20

The system of claim 15, wherein the means for including base-to-user broadcast information comprises means for including pilot tones for elements of an array antenna.

Claim 21

The system of claim 15, wherein the means for including base-to-user broadcast information comprises means for including pilot signals for a transversal equalizer.

Claim 22

The system of claim 15, wherein the means for including base-to-user broadcast information comprises means for including a paging signal.

Claim 23

The system of claim 15, wherein the means for including user-to-base random-access information comprises means for including a handoff request signal.

Claim 24

The method of claim 15, wherein the means for including user-to-base random-access information comprises means for including connection tree request information.
