  • Patent number: 11323958
    Abstract: If a cellular base station detects that it is about to shut down, either because no mobile terminals are within range, or because of a loss of power, for example because a user has deliberately switched it off, it first broadcasts a report that is about to shut down. This broadcast signal is picked up by the neighboring cells and used to update their neighbor lists, thus avoiding a false alarm which would otherwise be generated by the neighbors and transmitted to a centralized Operation Administration and Maintenance system when the shut-down cell fails to be detected on the next sampling cycle. The neighbors can then retain the shut-down base station in the neighbor list.

  • Patent number: 11121760
    Abstract: The invention described herein presents a system and method to overcome the distortions and affectations introduced by the highly variant channels of one or several antennas both in the transmitter and in the receiver. Unlike any existing invention that operates under the same conditions, this device uses a completely new reception technique based on the concept of virtual trajectories in which iterative calculations or solution of linear systems in operating time are not required, thus saving a considerable amount of operations. The receiver of this device manages to convert the fast variations of the channel into virtual antennas, thus achieving a considerable increase in the signal to noise-interference ratio. The resulting performance in terms of noise immunity is much better than any technique found so far and also requires a much smaller amount of calculations in the receiver.

  • Patent number: 10935624
    Abstract: An angle of arrival system is configured to efficiently measure phase differences. The angle of arrival system includes a master receiver for demodulating the signal received at one antenna and for implementing a tracking loop to identify the timing of symbols within the signal. This timing information can be fed back as a synchronization signal to a despreader in the master receiver and to a despreader in each of a number of slave receivers to synchronize the timing at which each signal is despread. Because despreading is synchronized, the outputs of the despreaders can be used to directly calculate phase differences between each pair of signals. In this way, the slave receivers do not need to implement a demodulator or a tracking loop. When the received signal is a non-spread signal, the phase differences between each pair of signals can be calculated directly from the modulated samples of each pair of signals without despreading.

  • Patent number: 10834663
    Abstract: Blind selection of a multi-frequency band indicator (MFBI) channel is disclosed. The crowded wireless spectrum can comprise overlapping bands, e.g., LTE bands 17 and 12. Whereas current standards allow setting the E-UTRA frequency to only one absolute radio-frequency channel number, alternative channel information can be distributed via SIB message. However, where a UE cannot read the MFBI information in a SIB message, the UE can be ignorant of a channel in an alternative band. Channel information for an alternative band can be sent to the UE as part of a radio resource control RRC message, for example, comprising a dEUTRACarrierFreqInfo value. The RRC connection release message can cause the UE to release a connection and then reestablish a new connection based on the channel information for then alternative band. This can allow mobile devices that do not support MFBI via SIB, to access channels in MFBI-type bands.

  • Patent number: 10812398
    Abstract: The present disclosure is directed generally to systems and methods for dynamically selecting a retransmission rate for communication between two devices. The retransmission rate may be selected after a transmission has failed between the devices. In some embodiments, the retransmission rate may be selected based on relative velocity of the devices. In some embodiments, the retransmission rate may be selected based on transmission channel characteristics. The retransmission rate may be selected such that the retransmission will be less than an allowable transmission rate based on a distance between the two devices.
