  • Publication number: 20200351641
    Abstract: Systems and methods are disclosed for triggering a long range extension mode of operation for a wireless device in a cellular communications network. In one preferred embodiment, the wireless device is a Machine Type Communication (MTC) device. In one embodiment, a node in the cellular communications network determines that the wireless device is to operate in the long range extension mode if there is difficulty in establishing communication between the wireless device and the cellular communications network. If the wireless device is to operate in the long range extension mode, the node activates one or more long range extension mechanisms with respect to the wireless device such that the wireless device operates in the long range extension mode. In this manner, the long range extension mode is selectively triggered for the wireless device.

  • Patent number: 10681605
    Abstract: Systems and methods are disclosed for providing optimized handover decisions for mobile devices participating in streaming services. In one embodiment, a serving base station in a cellular communications network obtains a play out buffer size for a streaming service of a mobile device. The serving base station then makes a handover decision based on the play out buffer size for the streaming service of the mobile device. In one embodiment, the streaming service is a downlink streaming service to the mobile device, and the play out buffer size is a size of a downlink play out buffer at the serving base station for the downlink streaming service to the mobile device. In another embodiment, the streaming service is an uplink streaming service from the mobile device, and the play out buffer size is a size of an uplink play out buffer at the mobile device for the uplink streaming service.

  • Patent number: 10568143
    Abstract: Methods, devices and systems for generating physical random access channel sequences that can be used to efficiently access a wireless network are disclosed. One exemplary method of accessing a wireless network includes generating a repeated orthogonal sequence by repeating a base orthogonal sequence, generating a random access sequence by applying a window function to the repeated orthogonal sequence, and accessing the wireless network using a random access procedure by selectively using the random access sequence. In an example, the base orthogonal sequence may be a Zadoff-Chu sequence. In another example, the window function may be a root-Hamming window.

  • Patent number: 10356797
    Abstract: The present disclosure concerns radio communication. More particularly, the present disclosure concerns a possible reduction in overhead signaling. The radio link quality of a first radio link (e.g., DL) as well as a second radio link (e.g., UL) is obtained 130. Also, the obtained radio link quality of the first radio link is compared 140 with the obtained radio link quality of the second radio link. This is done in order to establish whether a similarity in the radio link quality is within a predefined tolerance. Next, the signaling for both the first radio link and the second radio link is controlled 150 if, or when, the similarity of the radio link quality is determined to be within said predefined tolerance.

  • Patent number: 10314103
    Abstract: Techniques are disclosed for creating and using a pattern of radio resources to be shared in a cell between devices using an enhanced-coverage mode and at least one other category of devices. An example method includes forming (810) a resource pattern, the resource pattern indicating an allocation of first radio resources in a first cell to a first type of wireless device and indicating an allocation of second radio resources in the first cell to a second type of wireless device. The resource pattern is sent (820) to a second network node of the wireless communication system, e.g., a network node serving a neighboring cell, or to at least one wireless device, or to both. The resource pattern may be used in scheduling by the first network node or the second network node, or both.
