Abstract
Known stream classification service (SCS) has been improved for multi-link support. The low latency streams are identified with a SCSID. Improved SCS mechanisms may be used to allow a station to report link preference associated with low latency streams. Adapted SCS may also be used for negotiating a set of link for transmission of the low latency streams. An amended trigger frame may be used by the AP for scheduling the low latency streams. It is also proposed to adapt the target wake time (TWT) service period for allowing low latency dedicated TWT periods adapted to transmit streams identified with a SCSID.
Claims11
A communication method in a wireless network, comprising by a non-access point multi-link device, non-AP MLD, associated with an access point multi-link device, AP MLD:
- identifying a traffic stream by a stream classification service identifier, SCSID;
- reporting to the AP MLD one or more links on which the identified traffic stream is expected to be transmitted;
- and
- receiving from the AP MLD a trigger frame allocating resources for the transmission of one or more identified traffic streams,
- wherein the trigger frame comprises one element indicating that the trigger frame comprises a traffic stream identifier and one element indicating the traffic stream identifier.
A communication device in a wireless network, comprising a non-access point multi-link device, non-AP MLD, associated with an access point multi-link device, AP MLD, wherein the non-AP MLD comprises a processor configured for:
- identifying a traffic stream by a stream classification service identifier, SCSID;
- reporting to the AP MLD one or more links on which the identified traffic stream is expected to be transmitted;
- and
- receiving from the AP MLD a trigger frame allocating resources for the transmission of one or more identified traffic streams,
- wherein the trigger frame comprises one element indicating that the trigger frame comprises a traffic stream identifier and one element indicating the traffic stream identifier.
