  • Patent number: 12368619
    Abstract: An apparatus and method for a multi-service transmitter of an OFDM base station (BS) in a mixed numerology radio access network, wherein the transmitter uses a common cyclic prefix across all service types to eliminate inter-numerology interference (INI) by using a new Frequency Re-sampler (VR) component in the transmitter that converts streams of those services with smaller FFT sizes into a common larger FFT size in the frequency domain, which in effect increases their number of samples. The VR simply causes a multi-service transmitter to mimic a single-service transmitter thereby reducing the required number of ZF precoders to one and causing much fewer number of precoding operations. The transmitter sends resource configuration regarding the use of common CP for all services to each connected UE.

  • Patent number: 12267798
    Abstract: This application relates to wireless communications, including methods and apparatus to manage uplink (UL) transmit switching with multiple timing advance groups (TAGs) for wireless devices. A wireless device is configured to use multiple carriers selected from a set of available carriers that can be associated with different TAGs. When a second set of carriers, used after switching from a first set of carriers, includes carriers that belong to different TAGs, the wireless device determines whether to transmit on one or more first uplink transmission occasions for each of the carriers in the second set of carriers based on whether a first UL transmission occasion for at least one carrier overlaps a switching gap time period. The wireless device can disallow transmission on first UL transmission occasions of one or more carriers to accommodate the overlap.
