  • Patent number: 11206101
    Abstract: Disclosed in one embodiment is a downlink control channel decoding method of a wireless communication system, comprising the steps of: receiving setting information on a first resource and a second resource; blind-decoding reception signals on PDCCH resource candidates within the first resource determined by the setting information, so as to search for a PDCCH of the first resource; and blind-decoding reception signals on PDCCH resource candidates within the second resource determined by the setting information, and by blind-decoding, among the resource candidates, the remaining one or more resource candidates excluding one or more resource candidates, which include a resource area overlapping with the PDCCH having been searched for, so as to search for a PDCCH of the second resource. Therefore, since the number of PDCCH resource candidates required for blind-decoding is adjusted on the basis of an overlapping resource area, power consumption of a terminal can be reduced.

  • Patent number: 11196582
    Abstract: Implementations herein relate to information describing one or more internal states of a technical system. Implementations herein are provided for characterizing reliability of various different third party servers, at least when reporting third party device statuses, as well as adapting protocols for device ecosystems affected by such reliability. Latency can affect accuracy of device states represented by assistant devices. Certain servers can be characterized as especially delayed when reporting an updated device state in response to a user request, and, as a result, the third party server can be correlated to a metric that characterizes the relative latency of the third party server. When the metric fails to satisfy a particular threshold, a server and/or client associated with the “ecosystem” of third party devices can affirmatively operate to retrieve device state updates, rather than passively await updates from a corresponding third party server.

  • Patent number: 10129783
    Abstract: Systems and methods for transmission of measurement reports are provided. In some cases, once a mobile station transmits a measurement report for a cell, such as an uncontrolled cell, then the mobile station transmits some further minimum number of measurement reports. In some cases, a mobile station can only transmit measurement reports for a cell up to some maximum or for some specified time. The mobile station transmits measurement reports using two formats. In the first, the cell is identified using routing parameters; in the second, the cell is not identified using routing parameters.

  • Patent number: 10111216
    Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may be configured with a carrier aggregation (CA) configuration, which may include a large number of component carriers (CCs). Some of the CCs may be designated as basis CCs, and may have a flexible control channel configuration, while other CCs may be designated as supplemental CCs with a restricted control channel configuration. The restricted control channels may have a reduced number of decoding candidates, which may reduce the complexity and increase the likelihood of successfully decoding the control channels. For example, the restricted control channels may be limited to a subset of aggregation levels, a reduced control region, or other restrictions. In some cases, the CCs may be grouped into basis CCs and supplemental CCs based on physical uplink control channel (PUCCH) groups or based on CCs that utilize enhanced physical downlink control channels (ePDCCH).

    Abstract: A method in a network node for improving transmission control protocol, TCP, performance in a cellular network is provided. The network node handles TCP packet transferral between a user equipment and a server in the cellular network. The user equipment and the server are configured to adapt a retransmission timeout setting based on round trip times for performed TCP packet transferrals. When the network node obtains an indication of a handover outage being upcoming for the user equipment, the network node deliberately delays, in a time period preceding the indicated handover outage, a transferal of a TCP packet between the server and the user equipment to increase the round trip time for the TCP packet.
