  • Patent number: 10231182
    Abstract: Techniques for implicit indication of trigger frame start times are described. In various embodiments, an AP may be configured to transmit a trigger frame at the beginning of each target wake time (TWT) interval. In some embodiments, each STA that uses a given TWT interval may be configured to treat a TWT Start Time received from the AP not only as a start time for that TWT interval but also as a start time for the trigger frame to be received from the AP. In various embodiments, each STA in a TWT Group may wait to receive the trigger frame from the AP upon awakening during its TWT interval. The embodiments are not limited in this context.

  • Patent number: 10149139
    Abstract: A communication terminal has a wireless communication part and a control part. The control part sequentially switches a plurality of communication channels and discovers another communication terminal existing around the communication terminal itself. In the case of connecting to the other communication terminal found in the discovery, the control part determines which of the communication terminals transmits a connection request. In a case where the communication terminal itself does not transmit a connection request, the control part stops the discovery process and waists for reception of a connection request from the other communication terminal by using a given communication channel.

  • Patent number: 10142993
    Abstract: A receiving station in a Wireless Local Area Network (WLAN) implements a method to initiate a change in a receive operating mode during a current transmission opportunity (TXOP) of a transmitting station. The method sends a receive operating mode change to the transmitting station, where the receive operating mode change requests changes to at least one receive operating mode parameter associated with at least one transmission from the transmitting station to the receiving station. The method further changes the at least one receive operating mode parameter based on the receive operating mode change, where the at least one receive operating mode parameter changes from higher receiver resource usage to lower receiver resource usage. Changing the at least one receive operating mode parameter occurs only after completion of the current TXOP when the at least one receive operating mode parameter changes from higher receiver resource usage to lower receiver resource usage.

  • Patent number: 10085220
    Abstract: Disclosed is a method and system for compensating for excessive attenuation on an RF connection between a remote radio head (RRH) and an antenna of cell site. In an example configuration, in which first and second RF carriers of a cell site traverse different RF paths between respective RRHs and respective antenna, the second RF carrier may be subject to more attenuation than the first. Consequently, antenna transmission power of the second RF carrier may be below one or another threshold. For communication services to user equipment devices that involve both the first and second RF carriers, the diminished antenna transmission power of the second RF carrier may cause service degradation. In accordance with example embodiments, a controlling network entity may determine that the power is diminished, and responsively reallocate transmission power from an underutilized carrier to the second carrier, thereby boosting its transmission power and remediating service degradation.

  • Patent number: 10057391
    Abstract: An approach is provided for the application of network acceleration technologies to remote node traffic over GPRS tunneling protocols (GTP) in terrestrial mobile communications networks. A proxy device of a first network node receives a stream of data packets that are encapsulated in accordance with GTP. Each GTP packet is de-encapsulated by stripping GTP header from the packet, identifying the TEID (reflecting a respective GTP flow with which the GTP packet is associated), and maintaining a respective GTP payload (PDU). Acceleration functions are applied to the GTP PDUs, and the resulting acceleration packets are transmitted communications network link(s) to a proxy of a second network node. The second node proxy device receives the transmitted packets, and re-encapsulates each packet, in accordance with the GTP protocol, based at least in part on the respective TEID of the packet.
