ACCESS MANAGEMENT TO MULTI-USER UPLINK RANDOM RESOURCE UNITS BY A PLURALITY OF BSSs

A physical Access Point (AP) manages a plurality of BSS groups through Virtual APs. The AP periodically sends beacon frames informing of the profile of each BSS of the plurality of BSSs. To improve channel utilization, the trigger frame identifies a plurality of BSS groups, stations of which are allowed to access the resources units to transmit data during the reserved TXOP. The AP receives, during the reserved TXOP, data from one station of a first group identified in the trigger frame and data from one station (separate from the first one) of a second and separate group identified in the trigger frame. First group and second group use the same joint set of random access parameters for the random access procedure, thus ensuring equivalent fairness in accessing the offered the resources units to transmit data during the reserved TXOP to several BSSs.

The invention concerns a turbine engine with an axis of rotation B comprising a blower casing (10) and a blower (V) with movable blades (17). A clearance lies between the internal surface of the casing and the free ends of the blades. A bearing of the blower is connected to fixed parts of the turbine engine by connections such that, in the event of a load on the blower blades, these connections break and the axis of rotation of the blower oscillates about the axis of rotation B. The casing comprises, bonded to its internal surface and over at least part of the extent of the clearance, a layer of thermoformable foam (19) placed opposite the ends of the blades (17) of the blower (V). The layer of thermoformable foam (19) is partly covered with a layer of abradable substance (14), the thickness of the layer of abradable substance (14) is such that the free ends of the blades of the blower do not reach the layer of foam during the normal functioning of the turbine engine, and, in the event of a load on the blower, the free ends of the blades at least partly fragment the layer of abradable substance.

Mac/phy interface of wireless stations compliant to direct link and downlink transmissions in trigger-based multi-user transmissions

Aspects of the present disclosure generally relate to enhanced multi-user (MU) uplink (UL) protocols in wireless networks that allow non-UL transmissions to be performed simultaneously with triggered MU UL transmissions. A station may send a trigger frame triggering MU transmissions with an appropriate signaling to allow non-UL transmissions, i.e. transmission to another station, in a resource unit of the MU transmission. Examples of non-UL transmissions include Direct Link transmissions as well as downlink (DL) transmissions. The present disclosure regards how the MAC / PHY interface at an AP and at non-AP stations can be modified to efficiently handle the DiL and DL transmissions. On one hand, a non-AP station recipient of DiL or DL transmissions can use an 802.11 ax TRIGVECTOR to efficiently configure its PHY. On the other hand, the AP can configure its PHY to filter out the DiL / DL RUs.

Method and device for migrating a virtualised function in the event of a failure in the technical server environment

A method for migrating a virtualised function from a first server to a second server depending on data of technical environment parameters. The interfaces specified in the virtualised architectures effectively make it possible to deploy and manage virtualised functions with a view to implementing a service but these interfaces do not contain information relating to the data relating to the technical environment upon which the servers, the virtualised functions and subsequently the services and applications that rely on the virtualised functions are dependent. The migration method proposes virtualised architectures that take into consideration the technical environment parameters in order to move virtualised functions whose functioning could be impacted by a malfunction of one or more technical environment parameter(s).
