Provided is a wireless communication method by an access point (AP). The AP can be a sharing AP. The wireless communication method includes transmitting, by the sharing AP, a trigger frame to one or more shared APs to solicit extremely high throughput (EHT) multi-user (MU) physical layer protocol data unit (PPDU) transmissions from the one or more shared APs in a multi-AP coordinated downlink (DL) transmission. The trigger frame comprises an EHT variant common information field, a special user information field, and one or more EHT variant user information fields. A DL bandwidth (BW) subfield of the EHT variant common information field along with a DL BW extension subfield of the special user information field indicates a coordinated transmission BW for the multi-AP coordinated DL transmission.

A method, a computer-readable medium, and an apparatus are provided. The apparatus may include a first IAB-donor-CU. The apparatus may receive a first request from a second IAB-donor-CU to route a first traffic between a first IAB node associated with the second IAB-donor-CU and a second IAB node associated with the first IAB-donor-CU. The apparatus may receive from the second IAB-donor-CU first QoS information for the first traffic. The apparatus may transmit a request to a third IAB-donor-CU to route a second traffic between a third IAB node associated with the first IAB-donor-CU and a fourth IAB node associated with the third IAB-donor-CU, where at least a part of content of the second traffic is based on the first traffic.

A method and apparatus for transmitting cell load information in a wireless communication system is provided. According to an embodiment of the present invention, a master eNodeB (eNB) distributes UMTS terrestrial radio access network (UTRAN) cell load response to slave eNBs. According to another embodiment of the present invention, the master eNB aggregates evolved UTRAN (E-UTRAN) cell load response of slave eNBs to a radio network controller (RNC).

A network element selection method and a network element selector are provided. The network element selection method includes: receiving, by a network element selector, a request message sent by a base station, where the request message includes information about user equipment UE and a service chain head, the service chain head includes a session index, and the session index is empty or the session index is allocated by a first controller serving the UE; determining, by the network element selector based on the session index, a controller providing a service; and sending, by the network element selector, the request message to the controller providing the service, so that the controller providing the service serves the UE. In this application, the network element selector is deployed to provide a load balance function.

A method of OFDMA subcarrier allocation for stations in a wireless network includes determining a total downlink buffered traffic load for downlink traffic from a gateway device to the stations, and receiving a total uplink buffered traffic load for uplink traffic from the stations to the gateway device. The method further includes determining a first ratio of total downlink buffered traffic load for each station in relation to total downlink buffered traffic load for all stations, determining a second ratio of total uplink buffered traffic load for each station in relation to total uplink buffered traffic load for all stations, performing OFDMA subcarrier allocation for the downlink traffic by assigning available channel bandwidth proportional to the first ratio for each station, and performing OFDMA subcarrier allocation for the uplink traffic by assigning available channel bandwidth proportional to the second ratio for each station.

System and method for establishing a virtual access point (vAP) is described. A wireless network includes a router to provide access to external networks, physical access points (pAPs) to provide radio communications access to a user device, and a controller to form a vPA by layer two link aggregating the pAPs using access point and configuration information and send a virtual service set identifier (vSSID) to the pAPs. The vAP having a layer two data plane and control plane. The vAP provides a wireless coverage area equivalent to the pAPs using the vSSID, enable a user device to connect to the data plane via a data link, connect to the control place via layer two control links, and radio frequency connect to the pAPs. The controller and the pAPs configured to manage user data traffic flow between the router and the user device via the control and the data planes.

A method (700) by a first Centralized Unit, CU1, (20) in an Integrated Access and Backhaul, IAB, network includes transmitting (702) a first message to a second CU, CU2, (30) or receiving a first message from the CU2. The first message includes information indicating that a portion of offloaded traffic is to be returned to the CU1, and the offloaded traffic was previously offloaded from the CU1 to the CU2.

A method and apparatus are disclosed for using alternate paths for descendant nodes for backhaul failure link reporting. In one embodiment, a method for a network node that may be a parent node includes receiving information indicating at least one alternate path of at least one child IAB node to an IAB donor node, the at least one child IAB node being a wireless backhaul node; and using the received information to perform at least one of a backhaul wireless link failure recovery and load balancing of traffic. In another embodiment, a method for a network node that may be a child node includes receiving information indicating at least one alternate path of a parent IAB node to an IAB donor node, the parent IAB node being a wireless backhaul node for the child IAB node. The received information is used to perform at least one operational task.

A wireless communication network includes base stations serving cells. A first sector of a first cell served by a first base station is facing a second sector of a second cell served by a second base station. A controller receives performance data for each of the facing cells and dynamically assigns resource blocks to each base station. The base stations use the assigned resource blocks in the facing sectors to maximize allocation to user devices served in the facing sectors while minimizing interference. The controller may analyze the performance data over time and dynamically update the assigned resource blocks to each base station for the facing sectors at various time periods based on the analysis.

The performance and ease of management of wireless communications environments is improved by a mechanism that enables access points (APs) to perform automatic channel selection. A wireless network can therefore include multiple APs, each of which will automatically choose a channel such that channel usage is optimized. Furthermore, APs can perform automatic power adjustment so that multiple APs can operate on the same channel while minimizing interference with each other. Wireless stations are load balanced across APs so that user bandwidth is optimized. A movement detection scheme provides seamless roaming of stations between APs.
