Abstract
A non-AP MLD operates on multi-links with an UL TID-To-Link mapping. When activating the EML mode, it selects a set of EML links in which links the EML mode is applied, as a function of the UL TID-To-Link mapping, and it transmits to an AP MLD a notification specifying the selected set of EML links. In addition or as an alternative, while the non-AP MLD operates in an EML mode with a set of EML links, it transmits, in response to a BSRP TF received from the AP MLD over a first EML link of the set of EML links, a BSR frame reporting buffered traffic as a function of the UL TID-To-Link mapping, to the AP MLD, over the first EML link.
Claims25
A communication method in a wireless network, comprising, at a non-access point, non-AP, multi-link device, MLD operating on multi-links with an Uplink, UL, Traffic IDentifier(TID)-To-Link mapping:
- activating an Enhanced Multi-Link, EML, mode, wherein activating the EML mode includes selecting a set of EML links in which links the EML mode is applied, as a function of the UL TID-To-Link mapping, and transmitting to an AP MLD a notification specifying the selected set of EML links;
- and/or
- while the non-AP MLD operates in an EML mode with a set of EML links, transmitting, in response to a Buffer Status Report Poll, BSRP, trigger frame received from the AP MLD over a first EML link of the set of EML links, a BSR frame reporting buffered traffic as a function of the UL TID-To-Link mapping, to the AP MLD, over the first EML link.
11-17. (canceled)
A communication method in a wireless network, comprising, at an access point multi-link device, AP MLD, configured to carry out frame exchange operations, with at least one non-AP MLD, operating on multi-links with an Uplink, UL, Traffic IDentifier(TID)-To-Link mapping:
- transmitting to the non-AP MLD, over a first enabled link, a Buffer Status Report Poll, BSRP, trigger frame, TF;
- receiving from the non-AP MLD, over the first enabled link, a BSR frame reporting buffered traffic;
- and
- transmitting to the non-AP MLD, over the first enabled link, a Basic TF scheduling an UL resource to the non-AP MLD and containing a constraint, based on the UL TID-To-Link mapping, on the data to be transmitted within the scheduled UL resource.
A communication method in a wireless network, comprising, at an access point multi-link device, AP MLD, configured to carry out frame exchange operations, with at least one non-AP MLD, operating on multi-links with an Uplink, UL, Traffic IDentifier(TID)-To-Link mapping:
- transmitting to the non-AP MLD, over a first enabled link on which at least one UL TID is mapped according to the UL TID-To-Link mapping, a Buffer Status Report Poll, BSRP, trigger frame, TF.
25-37. (canceled)
A wireless communication device comprising at least one microprocessor configured for carrying out the method of claim 40.
A non-transitory computer-readable medium storing a program which, when executed by a microprocessor or computer system in a wireless device, causes the wireless device to perform the method of claim 48.
A communication method in a wireless network, comprising, at an access point, AP, affiliated with an AP multi-link device, MLD, and operating on a link for exchanging frames with a non-AP station affiliated with a non-AP MLD,
- transmitting, over the link, a Basic trigger frame, TF, scheduling an uplink, UL, resource to the affiliated non-AP station and containing a preferred AC subfield in a Trigger Dependent User Info field of a User Info field corresponding to the scheduled UL resource within the Basic TF;
- wherein the preferred AC subfield is set to a value for an AC for which at least one corresponding TID is mapped in UL to the link for the non-AP MLD by a Traffic IDentifier(TID)-To-Link mapping.
An access point, AP, affiliated with an AP multi-link device, MLD,
- adapted to operate on a link of a wireless network for exchanging frames with a non-AP station affiliated with a non-AP MLD, the affiliated AP comprising:
- a transmitter configured to transmit, over the link, a Basic trigger frame, TF, scheduling an uplink, UL, resource to the affiliated non-AP station and containing a preferred AC subfield in a Trigger Dependent User Info field of a User Info field corresponding to the scheduled UL resource within the Basic TF;
- wherein the preferred AC subfield is set to a value for an AC for which at least one corresponding TID is mapped in UL to the link for the non-AP MLD by a Traffic IDentifier(TID)-To-Link mapping.
