Transmission Power Control Technique Patents (Class 455/522)
  • Patent number: 10321465
    Abstract: A radio terminal includes a receiver, a controller, and a transmitter. The receiver receives first information on radio resources for direct communication from a base station by broadcast and second information on a threshold value from the base station. The controller performs the direct communication by use of a radio resource autonomously selected among the radio resources. The receiver directly receives a radio signal from another radio terminal during performing the direct communication by use of the radio resources, and the controller compares received power of the radio signal with the threshold value of the second information. The transmitter notifies the base station of first information on the received power in response to the received power being larger than the threshold value, and does not notify the base station of the information on the received power in response to the received power being smaller than the threshold value.

  • Patent number: 10321416
    Abstract: Apparatuses and methods for transmission power control are disclosed. A given transmission resource and a first transmission power are determined (202, 204) for transmission. Prior to transmitting on the given transmission resource it is determined (206) whether the resource is occupied or unoccupied. Upon detecting that the resource is occupied, a second, reduced transmission power is determined (210) such that a transmission using the second, reduced transmission power would not render the resource as occupied. The determination of the second transmission power is based at least partially on a predetermined maximum transmission power reduction value. Transmission (212) is done utilizing the given transmission resource using the second transmission power according to the determination.

  • Patent number: 10321412
    Abstract: The technique of beamforming is to be adopted in 5G NR systems in both DL and UL directions to combat the effect of acute path loss in the Giga hertz frequency region. With beamforming, the measured path loss in the UL and DL directions will be different even if the same carrier frequency is used for both DL and UL, due to the fact that the antenna gains are not unity as in the case in LTE/LTE-A systems. In view of this, embodiments of the present invention provide method and apparatus to handle the mechanism of UL transmit power control.

  • Patent number: 10320550
    Abstract: Techniques for estimating and reporting channel quality indicator (CQI) are disclosed. Neighboring base stations may cause strong interference to one another and may be allocated different resources, e.g., different subframes. A UE may observe different levels of interference on different resources. In an aspect, the UE may determine a CQI for resources allocated to a base station and having reduced or no interference from at least one interfering base station. In another aspect, the UE may determine multiple CQI for resources of different types and associated with different interference levels. For example, the UE may determine a first CQI based on at least one first subframe allocated to the base station and having reduced or no interference from the interfering base station(s). The UE may determine a second CQI based on at least one second subframe allocated to the interfering base station(s).

  • Patent number: 10321401
    Abstract: A first device may configure a second device, such as a sidelink receiver, so that an interference protection zone surrounding the second device may be dynamically adjusted in size based, for example, on various objectives and/or use cases recognized by the first device. The interference protection zone may be, for example, an area surrounding the second device, within which neighboring devices may be silenced. Changes to the interference protection zone may be achieved by providing a dynamic clear-to-send (CTS) transmit power scaling parameter, that is different from a pre-assigned constant parameter for CTS power control stored at the second device, to the second device from the first device. The second device may calculate CTS channel power using at least the dynamic CTS transmit power scaling parameter and the received RTS channel power. The second device may send a CTS message in a CTS channel at the calculated CTS channel power.

  • Patent number: 10270702
    Abstract: A kind of transmission method based on the learnable power model, which conducts periodic record for the historical change trend of the network. This method conducts weighting smooth processing on the round trip time and judges the changing trend of congestion control window. Then, it establishes model for the relationship between network power and the congestion control widow. When a new ACK is received, it immediately updates the window of power model. Finally, it forecasts the size of the congestion control window of the next time period by combining the congestion window and the network power changing trend. For the network packet loss or time-out events, the retransmission mechanism of traditional TCP is used, and when the packet loss ends, the power model process is used again. This invention reduces the influence of the network random events of the estimation error of traditional algorithm.

  • Patent number: 10244489
    Abstract: The present disclosure relates to a method for efficiently performing power control in situations where the UE is connected to both a MeNB and SeNB. The MeNB determines a power distribution ratio for the power to be used by the UE for uplink transmission to the MeNB and SeNB, determines the parameters PEMAX,MeNB and PEMAX,SeNB and sends these parameters to the SeNB/UE for use in power control. Moreover, update of the power distribution ratio is performed by the MeNB with assistance by the UE, which provides the MeNB with information on the pathloss on the secondary radio link to the SeNB, preferably by transmitting a virtual power headroom report, regarding the secondary radio link to the SeNB, to the MeNB, from which the MeNB derives the information on the pathloss for the secondary radio link.

  • Patent number: 10244485
    Abstract: A transmit power control method is disclosed. An example method includes obtaining a path loss between a to-be-adjusted wireless device and each of multiple wireless devices. A transmit power of the to-be-adjusted wireless device is adjusted according to a neighbor path loss and a target power. The neighbor path loss is a function of a neighbor path loss set. The neighbor path loss set is a set of path losses of a neighbor wireless device set. The neighbor wireless device set is a set of at least two wireless devices among the multiple wireless devices, where path losses between the at least two wireless devices and the to-be-adjusted wireless device are lowest. A layer closest to the to-be-adjusted wireless device is used as a reference to adjust the transmit power, and interference between wireless devices is reduced.

  • Patent number: 10225806
    Abstract: Methods and apparatuses are described herein for determining a transmit power based on clear channel assessment (CCA) thresholds. A station (STA) associated with a first Basic Service Set (BSS) may receive, from an access point (AP) associated with the first BSS, a clear channel assessment (CCA) value for a group of STAs associated with a second BSS. The CCA value may indicate a minimum CCA threshold for a packet received from the second BSS. The STA may then determine, based on the CCA value, a STA specific CCA parameter and a target CCA parameter. The target CCA parameter may be greater than or equal to the STA specific CCA parameter. Based on the STA specific CCA parameter and the target CCA parameter, the STA may determine a target transmit power control (TPC) parameter of the STA, wherein the sum of target TPC parameter and target CCA parameter is constant.
