  • Patent number: 10708875
    Abstract: A half-duplex radio device (100) generates a repetitive transmission of an uplink message to a base station (150) of the cellular network. The radio device (100) splits the repetitive transmission of the uplink message into a sequence of multiple transmit periods and configures at least one measurement gap between the transmit periods. In the transmit periods, the radio device (100) sends the repetitive transmission to the base station. In the at least one measurement gap configured between the transmit periods, the radio device (100) temporarily switches to receiving at least one downlink signal from the base station (150). Based on the received at least one downlink signal, the radio device (100) estimates a frequency error of a reference frequency source of the radio device (100).

  • Patent number: 10581494
    Abstract: A base station, e.g., for massive MIMO, has channel receivers, each connected to a respective antenna among a plurality of antennas to receive an RF transmission signal generated by a communication device (CD). Each channel receiver has a channel front-end module, which has a first bandwidth and converts the RF transmission signal into one or more first analog baseband signals. The channel receivers are collectively operable to define a spatial beam focus at the CD, based on channel state information of the CD. The base station has pilot signal receivers, each connected to a respective antenna among the plurality of antennas to receive an RF pilot signal generated by the CD or another CD. Each pilot signal receiver has a pilot signal front-end module, which has a second bandwidth that is smaller than the first bandwidth and converts the RF pilot signal into one or more second analog baseband signals.

  • Patent number: 10149345
    Abstract: The invention is directed to systems, methods and computer program products for discontinuous signaling in a mobile communication network. User equipment (UE)/mobile terminal requests slotted transmissions and, in response to the network authorizing slotted transmissions, communication of subsequent UE transmissions are slotted, such that a minimum time period is required to elapse between each UE transmission. In specific embodiments of the invention the minimum time period is a predetermined time period known in advance to the user equipment and network. In other embodiments of the invention the user equipment slotted transmission requests includes a requested minimum time period, which may be approved or revised by the network. In still further embodiments the network, upon receiving the request for slotted transmissions, determines the minimum time period.

  • Patent number: 10009797
    Abstract: A radio device applies a carrier frequency for transmission of data between the radio device and a base station of a cellular network. Further, the radio device configures a measurement time interval in which the radio device temporarily switches from the transmission of data to receiving at least one broadcast signal conveying system information from the base station. Based on the received at least one broadcast signal, the radio device estimates an offset of the carrier frequency as applied by the radio device to a frequency of a carrier signal as received from the base station.

  • Patent number: 9596103
    Abstract: A user-device implemented method includes encoding a first digital signal to generate a first digital baseband signal and modulate the first digital baseband signal to generate one or more RF signals corresponding to one or more frequency bands. The one or more RF signals are transmitted via one or more antennas. Substantially simultaneously with the transmission of the one or more RF signals, a second one or more RF signals is received via the one or more antennas. The second one or more RF signals are demodulated to generate a second digital baseband signal. The first digital baseband signal is subtracted from the second digital baseband signal to generate a modified second digital baseband signal.
