Wireless network for requesting a contention channel
First Claim
Patent Images
1. A wireless network, comprising:
- a base station in communication with a plurality of terminals;
at least one terminal of the plurality of terminals operable to be assigned to a radio cell of the base station for exchanging user data and control data, the terminal being further operable to transmit a first signaling sequence as an indication to use one of a plurality of contention channels;
wherein the base station, upon receiving the first signaling sequence, is operable to broadcast a provision message indicating a channel that is available to the plurality of terminals for contention-based access.

Abstract
A wireless network employs at least a base station (1 to 3) and a plurality of assigned terminals (4 to 14) for exchanging user data and control data. That base station (1 to 3) includes a device (21, 22) for correlating a signaling sequence transmitted by at least one terminal (4 to 14) to indicate the wish to use a contention channel and for detecting the pulse evolved from a received and correlated signaling sequence. After a signaling sequence has been detected, the base station (1 to 3) transmits a provision message over a contention channel to be utilized by the assigned terminals (4 to 14).

17. A terminal operable to be assigned a radio cell in a wireless network of a plurality of terminals for exchanging user data and control data with a base station, the terminal comprising:
-
a transmitter operable to transmit a first signaling sequence to the base station, the signaling sequence being indicative of a request for a channel to be made available for contention-based access by the transmitter; and a receiver operable to receive a provision message from the base station subsequent to the transmission of the first signaling sequence by the transmitter, the provision message indicating the channel that is available to the plurality of terminals for contention-based access. - View Dependent Claims (18, 19, 20, 21, 22, 23, 24)

25. A method of exchanging user data and control data in a wireless network of a plurality of terminals between a base station and a terminal of the plurality of terminals operable to be assigned a radio cell, the method comprising:
-
transmitting a signaling sequence from the terminal to the base station, the signaling sequence being indicative of a request by the terminal to use a channel for contention-based access; detecting the signaling sequence by the base station; and broadcasting a provision message by the base station to the plurality of terminals in response to the request, the provision message indicating the channel that is available to the plurality of terminals for contention-based access. - View Dependent Claims (26, 27)
