  • Patent number: 11394450
    Abstract: Methods and systems for Long Term Evolution (LTE) and Fifth Generation (5G) beam index filtering are presented. According to one aspect, a method for beam index filtering comprises receiving a beam index that was estimated based on information received from a User Equipment (UE); storing the received beam index into a queue of length N for storing received beam indexes, N being greater than one; selecting a beam index from the queue according to a filtering algorithm; and using the selected beam index for transmissions to the UE. In one embodiment, a majority vote algorithm is employed to select the beam index that appears most often in the queue. Where there is a tie between two or more beam indexes, the beam index that was most recently added to the queue is selected. The same concepts may be applied to filter input data or parameters other than beam indexes.

  • Patent number: 11108789
    Abstract: Research efforts to detect and prevent possible attacks on vehicles have led to various defense schemes that are capable of preventing attacks and/or determining the presence/absence of an attack on the in-vehicle network. However, these efforts still cannot identify which Electronic Control Unit (ECU) on the in-vehicle network actually mounted the attack. Moreover, they cannot detect attacks by an adversary that impersonates ECUs injecting in-vehicle messages aperiodically. Identifying the source of an attack is essential for efficient forensic, isolation, security patch, etc. To fill these gaps, a method is presented for detecting and identifying compromised ECUs in a vehicle network.

    Abstract: There is provided a method performed by a wireless device for supporting transmission to a network node in a wireless communication network according to an embodiment. The method is adapted for a wireless network based on LTE, wherein the wireless device is allowed to transmit on a set of Resource Elements, REs, allocated for transmission to the network node. The method comprises the step (S1) of determining at least one transport format control parameter for at least a first part of the set of REs allocated for transmission. The method further comprises the step (S2) of transmitting, to the network node, an indication representing the at least one determined transport format control parameter on at least a second part of the set of REs allocated for transmission to notify the network node of the determined transport format control parameter(s).

  • Patent number: 10660017
    Abstract: A first communications device (1002) and a method therein for Device-to-Device (D2D) communication with a second communications device (1004) using a first Radio Access Technology (RAT) or a second RAT. The first and second communications devices are operating in a communications network (1000). The first communications device transmits 5 the second communications device, by means of the first RAT, information relating to a proximity service provided by the second RAT. Thereby the information enables the second communications device to determine whether to use the first RAT or the proximity service provided by the second for D2D communication with the first communications device.

  • Patent number: 10524108
    Abstract: Certain aspects of the present disclosure provide methods for wireless communications by a base station and a user equipment in a network. An exemplary method generally includes performing a discovery procedure to identify one or more devices through which the UE may indirectly communicate with a base station in the network and deciding based on one or more criteria whether to communicate with the base station directly or to communicate with the base station indirectly via a device identified by the discovery procedure. According to certain aspects, when a UE is in communication with a network indirectly, the network might page the UE directly, indirectly, or both.
