A method by a wireless device functioning as a beamformer station in a wireless network to perform a sounding procedure. The method includes generating a NDPA frame, wherein the NDPA frame includes a sounding dialog token field, wherein bit B0 of the sounding dialog token field is set to binary ‘1’ and bit B1 of the sounding dialog token field is set to binary ‘1’ to indicate that the NDPA frame is an extremely high throughput (EHT) NDPA frame and wirelessly transmitting the NDPA frame to one or more beamformee stations. The NDPA frame may include an indication of whether a beamformee station should acknowledge the NDP announcement frame or not. The NDPA frame may be transmitted in a first frequency band, while a beamformed data frame is transmitted in a second frequency band that is a higher frequency band than the first frequency band.

The application provide an access method, including: sending, to an access point, a first frame that carries uplink transmission requirement information; and if a second frame that carries information about an uplink transmission resource is received from the access point within agreed time period, sending uplink multi-user transmission data to the access point, where the uplink multi-user transmission data is transmitted on the uplink transmission resource; or if the second frame is not received within an agreed time period, accessing, by a station, a channel in a contention access manner that is based on carrier sense CSMA/CA.

Data services for workloads are often provided with a service level agreement specifying various performance guarantees (e.g., latency, availability, scalability, and consistency). Single-master architectures, in which updates t the data set are constrained to a single server, may limit the fulfillment of some performance guarantees. Presented herein are multi-master architectures, in which the server set is partitioned into at least two masters are permitted to update the data set and at least one non-master that is not permitted to update the data set. Non-masters that receive a request to update the data set forward the request to a master server for application to the data set. A master that receives the request applies it to the data set and propagates the update to other master and non-master servers. Conflicting updates may be resolved through a variety of conflict resolution techniques, optionally designating one master server as a conflict resolution server.

By analyzing the apps on a portable computing device, the communication modes used by the portable computing devices and the communication requirements of the apps at a given time, an ideal communication mode given a certain mix of apps operating on a portable computing device at a given point in time may be determined.

Adaptive payload extraction in wireless communications involving multi-access address packets are described herein. A device can be configured to detect a synchronization sequence of a nested data packet, the nested data packet having synchronization sequences placed in series ahead of a payload, the synchronization sequences including the synchronization sequence; evaluate blocks after the synchronization sequence in the nested data packet to identify the blocks as either additional ones of the synchronization sequences or the payload in the nest data packet; and extract the payload.

A system may comprise at least one third party server that supports at least one third party content provider and an information storage device for storing capability information. The at least one third party server may be separate from at least one server that supports the service. When a packet-switched message is transmitted from a mobile wireless device of a subscriber to the at least one third party content provider, the at least one server that supports the service may not reveal a mobile phone number of the subscriber to the at least one third party content provider. The at least one third party server may receive the packet-switched message from the at least one server that supports the service with a mapping identifier that maps to the mobile phone number of the subscriber that transmitted the packet-switched message.
