  • Patent number: 11997031
    Abstract: A base station and wireless device are configured to support TDD operation. In exemplary embodiments, the base station or UE can make use of the available symbols in the DwPTS or UpPTS of a special subframe respectively for NB-IoT transmissions. In one example, the base station can use OFDM symbols in the DwPTS to repeat in a predetermined manner some of the symbols transmitted in an immediately preceding downlink subframe, or in a succeeding downlink subframe. In other embodiments, the UE can use symbols in the UpPTS to repeat in a predetermined manner some of the symbols transmitted in the immediately succeeding uplink subframe, or in a preceding uplink subframe. The symbols repeated in the special subframe can be coherently combined at the receiver with corresponding symbols transmitted in a downlink or uplink subframe to improve decoding performance, reduce errors, improve channel estimation, and increase system capacity.

  • Publication number: 20240146586
    Abstract: Embodiments herein disclose e.g. a method performed by a wireless device (10) for handling communication for the wireless device in a second wireless communication network. The second wireless communication network coexists with a first wireless communication network on a same bandwidth in frequency, wherein the first wireless communication network applies a first shift in frequency in uplink transmissions. The wireless device receives from a radio network node (12, 13), an indication indicating application of a second shift in frequency to uplink transmissions in case the second wireless communication network uses Frequency Division Duplex (FDD). The wireless device further applies the second shift in frequency to uplink transmissions, wherein the second shift defines a shift in frequency to a subcarrier relative to a subcarrier grid of the second wireless communication network or a shift in frequency to the subcarrier grid of the second wireless communication network.

  • Patent number: 11856648
    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.
