Abstract
A communication method in a communication network comprising a plurality of nodes connected to at least one access point node, the nodes being able to transmit data on at least one communication channel using a contention access method according to a contention parameter set, the method comprising, at a node, transmitting a given type of traffic during a dedicated service period allocated by the access point node, and switching, at the end of the dedicated service period, from a first contention parameter set to a second contention parameter set for contention access to the communication channel after a successful transmission of the given type of traffic during the dedicated service period.
Claims28
A communication method in a communication network comprising a plurality of nodes connected to at least one access point node, the nodes being able to transmit data of a first access category, AC, outside Target Wake Time, TWT, service periods, SPs, on at least one communication channel using a contention access method according to a contention parameter set associated with the first AC, the method comprising, at a node:
- transmitting data of the first AC during a dedicated TWT SP allocated by the access point node, and
- after a successful transmission of the data of the first AC during the dedicated TWT SP, switching, at the end of the dedicated TWT SP, from a first contention parameter set associated with the first AC to a second contention parameter set associated with the first AC, for contention access to the communication channel to transmit data of the first AC,
- whereas in case of unsuccessful transmission of the data of the first AC during the dedicated TWT SP, the first contention parameter set associated with the first AC is maintained at the end of the dedicated TWT SP, for contention access to the communication channel to transmit data of the first AC.
A communication method in a communication network comprising a plurality of nodes connected to at least one access point node, the nodes being able to transmit data of a first access category, AC, outside Target Wake Time, TWT, service periods, SPs, on at least one communication channel using a contention access method according to a contention parameter set associated with the first AC, the method comprising, at the access point node:
- transmitting information relating to the at least one second contention parameter set associated with the first AC to a node,
- allocating a dedicated TWT SP for transmission of data of the first AC;
- wherein the second contention parameter set is intended to be used by the node at the end of the dedicated TWT SP, and after a successful transmission of the data of the first AC during the dedicated TWT SP instead of a first contention parameter set associated with the first AC and intended to be used by the node for contention access to the communication channel to transmit data of the first AC, whereas in case of unsuccessful transmission of the data of the first AC during the dedicated TWT SP, the first contention parameter set associated with the first AC and intended to be used by the node for contention access to the communication channel to transmit data of the first AC is maintained at the end of the dedicated TWT SP.
A communication device forming a node in a communication network comprising a plurality of nodes connected to at least one access point node, the nodes being able to transmit data of a first access category, AC, outside Target Wake Time, TWT, service periods, SPs, on at least one communication channel using a contention access method according to a contention parameter set associated with the first AC, the communication device forming the node comprising a microprocessor configured for carrying out the following steps:
- transmitting data of the first AC during a dedicated TWT SP allocated by the access point node,
- after a successful transmission of the data of the first AC during the dedicated TWT SP, switching, at the end of the dedicated TWT SP, from a first contention parameter set associated with the first AC to a second contention parameter set associated with the first AC for contention access to the communication channel to transmit data of the first AC.
An access point in a communication network comprising a plurality of nodes connected to the access point, the nodes being able to transmit data of a first access category, AC, outside Target Wake Time, TWT, service periods, SPs, on at least one communication channel using a contention access method according to a contention parameter set associated with the first AC, the access point being characterized in that it comprises at least one microprocessor configured for carrying out the following steps:
- transmitting information relating to the at least one second contention parameter set associated with the first AC to a node,
- allocating a dedicated TWT SP for transmission of data of the first AC;
- wherein the second contention parameter set is intended to be used by the node at the end of the dedicated TWT SP, and after a successful transmission of the data of the first AC during the dedicated TWT SP, instead of a first contention parameter set associated with the first AC and intended to be used by the node for contention access to the communication channel to transmit data of the first AC,
- whereas in case of unsuccessful transmission of the data of the first AC during the dedicated TWT SP, the first contention parameter set associated with the first AC and intended to be used by the node for contention access to the communication channel to transmit data of the first AC is maintained at the end of the dedicated TWT SP.
