  • Publication number: 20220255778
    Abstract: Methods, systems, and devices for wireless communications are described. A base station may transmit signaling that configures a wireless device to use a multi-level coding (MLC) procedure to communicate with a base station. Based on receiving the signaling, the wireless device may select a channel quality indicator (CQI) index from a set of CQI indices that are associated with an MLC procedure. In some examples, the wireless device selects the CQI index from a set of CQI indices that includes both bit-interleaved coded modulation (BICM)-based and MLC-based CQI indices. In other examples, the wireless device selects the CQI index from a set of CQI indices that includes solely MLC-based CQI indices. The wireless device may transmit the selected CQI index to the base station. And the base station may select a modulation and coding scheme for subsequent transmissions to the wireless device based on the received CQI index.

  • Publication number: 20220248356
    Abstract: Methods, systems, and devices for wireless communication are described. A base station may transmit a set of synchronization signals (SSs) with a first periodicity to a channel engineering device and one or more other wireless devices. The base station may transmit a message to configure the channel engineering device with one or more signaling directions and a second periodicity for the channel engineering device to transmit the set of SS, the second periodicity different from the first periodicity. The one or more signaling directions and the second periodicity may be configured for adjusting a coverage area of the set of SS after transmission from the base station. The base station may receive, from a user equipment (UE) or other wireless device, a second message that includes an indication of whether the set of SS were received by the UE directly from the base station or via the channel engineering device.

  • Patent number: 11405128
    Abstract: Aspects of the disclosure relate to minimizing the block error rate (BLER) experienced by a user equipment (UE) upon a downlink beam switch at the base station. The base station may mitigate the link adaptation convergence transient upon performing a beam switch by modifying the modulation and coding scheme (MCS) according to a difference in reference signal received power (RSRP) between the old beam and the new beam. The base station may further adjust the MCS utilizing an outer-loop link adaptation process or channel state feedback (CSF) provided by the UE after the beam switch. Other aspects, features, and embodiments are also claimed and described.
