Method and system for contention resolution in telecommunication networks
First Claim
1. A method for contention resolution in a communications network, the method comprising:
- transmitting, by a base station, a first contention message for a network resource during a first time interval for use of the network resource in the next time interval;
counting, by the base station, a number of contention messages received during the same first time interval from other base stations contending for the next time interval;
if one or more contention messages are received during the first time interval, deferring, by the base station, a use of the network resource in the communications network during the next time interval; and
if one or more contention messages are not received during the first time interval, using, by the base station, the network resource during the next time interval,wherein the transmitting and determining are performed concurrently or in parallel with a use of the network resource by the base station during the first time interval, and the transmitting is not performed over the network resource for which contention is being performed.

Abstract
A method and system for contention resolution in a communications network are disclosed. As one example, a method for contention resolution in a communications network is disclosed. The method includes the steps of transmitting a first contention message during a first time interval, determining if a second contention message has been received during the first time interval, if the second contention message has been received during the first time interval, deferring a use of a network resource in the communications network, and if the second contention message has not been received during the first time interval, using the network resource during a second time interval.

11. A method for contention resolution by a first device in a communications network, the method comprising:
-
determining that a channel sharing contention condition exists; generating a random number associated with a predefined duration of a contention window; sending a first messaging packet or frame during a first contention time slot for using a network resource in the next contention time slot, the first messaging packet or frame associated with a predetermined probability value; counting a number of messaging packets or frames received from one or more other devices during the first contention time slot; if one or more messaging packets or frames are received from the one or more other devices, deferring use of a channel in contention during the next contention time slot; and if one or more messaging packets or frames are not received from the second device, using the channel in contention during the next contention time slot, wherein sending a first messaging packet or frame and determining if at least one messaging packet or frame was received from one or more other devices are performed concurrently or in parallel with a use of the channel in contention, and sending a first messaging packet or frame is not performed over the network resource for which contention is being performed. - View Dependent Claims (12, 13, 14, 15, 16, 17)

18. A system for contention resolution in a communications network, the system comprising:
-
a first base station in the communications network; a second base station in the communications network; a second network; and a plurality of communication links connected to the first base station, the second base station, and the second network, the plurality of communication links coupling the first base station to the second base station for communication, wherein the first base station is configured to; transmit, by the first base station, a first contention message during a first time interval for using a network resource in the next time interval; determine if a second contention message has been received during the first time interval by the second base station; if the second contention message has been received during the first time interval, defer a use of a network resource in the communications network during the next time interval; and if the second contention message has not been received during the first time interval, use the network resource during the next time interval, wherein the first base station is configured to transmit the first contention message and determine if the second contention message has been received concurrently or in parallel with a use of the network resource by the first base station during the first time interval, and transmission of the first contention messages is not performed over the network resource for which contention is being performed. - View Dependent Claims (19)
