  • Patent number: 10314041
    Abstract: The various embodiments provide methods implemented in a MSMA communication device for managing a victim subscription's de-sense by proactively implementing an RF coexistence management strategy on the victim subscription when an RF coexistence event starts. In various embodiments, a MSMA communication device may implement an RF coexistence management strategy by determining when an aggressor subscription will de-sense a victim subscription and configuring the victim to anticipate and mitigate de-sense during the aggressor's transmissions. Thus, the various embodiments may provide dramatic improvements to the victim's overall reception performance and overall user experience.

    Abstract: The present invention provides a novel adaptive power configuration method and corresponding base stations in a Het Net. According to the present invention, some specific subframes of a serving base station are scheduled to serve victim UEs, while the corresponding subframes of an aggressor base station can be scheduled to serve its UEs with adaptively adjusting the transmit power instead of thoroughly muting. This adaptive power configuration scheme can efficiently reduce the interference in Het Nets to guarantee the workability of victim UEs, meanwhile more capacity performance gain can be achieved with backward compatibility to legacy UEs.

  • Patent number: 10039082
    Abstract: The present invention relates to a method and an apparatus for a user equipment receiving MBMS service processing a semi-permanent scheduling from an MBSFN subframe. A method for a user equipment receiving the multimedia broadcast multicast service (MBMS) processing a downlink scheduling in a mobile communication system of the present invention comprises: a detection step of detecting the occurrence of the downlink scheduling in a random transmission time interval; a decision step of deciding whether to process the downlink scheduling, depending on whether the user equipment is set to a transmission mode 9 or whether the transmission time interval belongs to a multimedia broadcast multicast service single frequency network (MBSFN) subframe; and a processing step of processing or disregarding the downlink scheduling based on the result of the decision.

  • Patent number: 10015070
    Abstract: Systems and methods are described for extending coverage of a wireless device. A handover trigger threshold may be established for a plurality of wireless devices located in a coverage area of an access node. An attachment request may be received at the access node from at least one wireless device having a power class different from a common power class of the plurality of wireless devices. Based on the reported power class, the access node may adjust a handover trigger threshold for the at least one wireless device.

  • Patent number: 9991947
    Abstract: The present disclosure is directed to a method for calibrating a communications device. The method may include the step of determining a first coefficient based on correction data obtained by the transition from an initial open loop power operation to a power level of a closed loop operation. The method may also include the step of determining a second coefficient of transmitter gain based on the power of one or more transmissions by the communications device. A further step of the method may include determining a strength of a downlink signal received by the communications device from a satellite computed from knowledge of a receiver gain represented by the first coefficient. The method may also include the step of determining a transmit power level for the communications device based on the strength of the downlink signal, the first coefficient, and the second coefficient of transmitter gain.

  • Patent number: 9955512
    Abstract: Provided is a method for transmitting a HARQ (hybrid automatic repeat request) ACK (acknowledgment)/NACK (not-acknowledgement) response from user equipment in which two serving cells are set. The method comprises the steps of: receiving a first transport block through a first serving cell which is set in a first transmission mode, in which up to two transport blocks are supported; determining an HARQ ACK/NACK response which includes a first response to the first transport block; and transmitting the HARQ ACK/NACK response, wherein the first response is the same as a response used when two transport blocks have been received through the first serving cell.

  • Patent number: 9936453
    Abstract: Methods, systems, and devices for wireless communication are described. The described techniques allow a user equipment (UE) to conserve power after transitioning from one coverage mode to another coverage mode based on power consumption estimates. The UE may make a determination on whether to modify its current extended discontinuous reception (eDRX) values by either triggering an unscheduled timing update or waiting for a scheduled timing update. For instance, the UE may estimate power consumption based on current eDRX values and the time remaining until a scheduled timing update procedure and compare this estimate to power consumption estimate based on modified eDRX values and the amount of power consumed to perform an unscheduled timing update procedure. Based on the comparison, the UE may update its eDRX values through an unscheduled TAU or through the regularly scheduled TAU procedure.

  • Patent number: 9918322
    Abstract: A radio resource management (RRM) system and method manages radio resources in a wireless network of radio access points (APs). In some embodiments, the channel and/or frequency of radios of the APs are managed based on a prioritization scheme of the radios. In some embodiments, the transmit powers of the radios are managed based on the prioritization scheme. The priorities of the radios is partially based on the priorities of clients connected to the radios. In some embodiments, the RRM system is a centralized controller system. In some embodiments, the RRM system forms a hierarchical network of child and parent nodes. The parent nodes are configured to manage the radios associated with the parent and its child nodes. The parent node with the smallest number of child nodes, which are associated with the selected radio and its neighboring radios, is managing these radios.

  • Patent number: RE47110
    Abstract: Systems and methodologies are described that facilitate reporting an uplink power headroom (UPH) during an E-DCH transmission in a CELL_FACH state. For a E-DCH transmission, a reduced measurement period can be utilized in order to report a UPH measurement. In particular, the reduced measurement period can be less than 100 milliseconds. The UPH measurement can be communicated based upon receipt of AICH/E-AICH and transmission of DPCCH for a configurable number of radio frames. The UPH measurement can be based upon the transmitted power prior to actual data transmission. Additionally, the UPH measurement can be included within scheduling information portion of a MAC header.
