Abstract: A wireless access node serves wireless User Equipment (UEs) based on wireless network slices that are used by the UEs. In the wireless access node, node circuitry generates initial schedules for the UEs. Radio circuitry in the wireless access node wirelessly communicates with the UEs based on the initial schedules. The node circuitry detects a scheduling contention for the UEs and responsively determines scheduling priority based on the wireless network slices used by the UEs. The node circuitry generates priority schedules for the UEs based on the scheduling priority. The radio circuitry wirelessly communicates with the UEs based on the priority schedules. The node circuitry may use normal scheduling again when the contention subsides.

Abstract: Examples of techniques for Association Identifier (AID) assignment are disclosed. In an example, a controller managing an AP may allocate a set of numbers for AID assignment to clients connecting to VAPs in a multiple BSSID set of the AP. The controller may configure the AP to assign AIDS to non-Multi-Link (non-ML) clients from a first subset of the set based on a first monotonic sequence and assign AIDS to ML clients from a second subset of the set based on a second monotonic sequence. The AP may receive an association request from a client to associate with a VAP of the multiple BSSID set, determine whether Multi-Link operation (MLO) is enabled for the client, and in response to determining that MLO is disabled for the client device, assign a first AID to the client from the first subset based on the first monotonic sequence.

The transmitter, in operation, transmits the first uplink signal with the determined first transmission power and transmits the second uplink signal with the determined second transmission power.

Abstract: Embodiments include methods for downlink (DL) transmission by a network node in an integrated access backhaul (IAB) network. Such methods include receiving, from an upstream node in the network, first timing offset information related to communications between the network node and the upstream node. Such methods include transmitting a DL signal or channel, to one or more downstream nodes, based on a DL transmission timing for the network node. The DL transmission timing is determined from the network node's DL reception timing of signals or channels transmitted by the upstream node and a second function of the first timing offset information, which is determined based on a first function of the first timing offset information (when the first function is greater than a threshold) or on an alternate timing offset (when the first function is not greater than the threshold). Embodiments also include network nodes configured to perform such methods.
