  • Publication number: 20260181629
    Abstract: According to some embodiments, a method is performed by a reduced capability (RedCap) wireless device. The method comprises: receiving a physical downlink shared channel (PDSCH), the PDSCH including scheduling for an uplink transmission; determining whether a time duration between receiving the PDSCH and a start of the scheduled uplink transmission is greater than a threshold; and upon determining that the time duration between receiving the PDSCH and the start of the scheduled uplink transmission is greater than the threshold, transmitting the scheduled uplink transmission. The threshold depends on whether the PDSCH is received in a bandwidth that is larger than a reduced bandwidth associated with RedCap wireless devices.

  • Patent number: 12362973
    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: 12355600
    Abstract: Systems and methods for selecting subcarriers to be used for sub-Physical Resource Block (PRB) transmission and, in some embodiments, for mapping Demodulation Reference Signals (DMRS) to resources on the selected subcarriers are disclosed. In some embodiments, a method of operation of a radio node for providing sub-PRB transmission comprises selecting two adjacent subcarriers from a set of three allocated subcarriers that are allocated for a sub-PRB transmission that uses Single Carrier Frequency Division Multiple Access (SC-FDMA) Pi/2 Binary Phase Shift Keying (BPSK) modulation using only two adjacent subcarriers out of the set of three allocated subcarriers with Discrete Fourier Transform (DFT) spread length of 2. In some embodiments, the selection is such that the selected adjacent subcarriers varies, e.g., from one cell to another. In doing so, interference is distributed.
