    Abstract: Methods, systems, and devices for dynamic monitoring modes for synchronization signal block (SSB) transmissions are described. A user equipment (UE) may monitor one or more first SSB transmission opportunities for SSB transmissions from a base station and determine an SSB failure rate. Based on the failure rate, the UE may select a mode for monitoring one or more second SSB transmission opportunities. For example, if the failure rate is greater than a threshold, the UE may select a first mode for monitoring a first quantity of the one or more second SSB transmission opportunities. Additionally, if the failure rate is less than the threshold, the UE may select a second mode for monitoring a second quantity different than the first quantity of the one or more second SSB transmission opportunities. The UE may monitor the one or more second SSB transmission opportunities according to the selected mode for monitoring.

    Abstract: Methods, systems, and devices for wireless communications are described. The described techniques provide for dynamic updates to beam failure detection (BFD) reference signals (RSs) and path loss RS using medium access control-control element (MAC-CE) or downlink control information (DCI). For example, the quasi co-location (QCL) of periodic CSI-RS may be dynamically updated by the MAC-CE or DCI when the periodic CSI-RS is for BFD RS. Also, a semi-persistent CSI-RS or aperiodic CSI-RS may act as a BFD RS. An enhanced update procedure may be used to update the path loss RS dynamically using MAC-CE or DCI. In some cases, the path loss RS parameters updated via MAC-CE or DCI may overwrite the previously RRC configured path loss RS parameters. In another example, if the path loss RS is not configured, then the path loss RS by default may be the spatial relation reference signal of the corresponding uplink beam.

    Abstract: Techniques for wireless communications are described. A user equipment (UE) may initially configure a set of channel estimation parameters for a set of radio frequency spectrum subbands of a bandwidth part (BWP) of a transmission opportunity (TxOP). In some examples, the UE may identify an unavailable radio frequency spectrum subband within the BWP. Based on the identification, the UE may reconfigure the channel estimation parameters to avoid performing unnecessary channel estimation processes on the unavailable radio frequency spectrum subband. As part of reconfiguring the channel estimation parameters, the UE may set log-likelihood ratio (LLR) values of subcarriers associated with the unavailable radio frequency spectrum subband to a null value, thereby experiencing improvements in efficiency and reliability of channel estimation for the BWP.

    Abstract: A receiver circuit, including a multi-stage QAM de-mapper, for receiving a QAM data signal is disclosed. A first de-mapper circuit recovers a set of encoded data bits from the QAM data signal by calculating a plurality of distances between a received QAM symbol and each of a plurality of possible constellation points. A second de-mapper circuit then generates a set of unencoded data bits for the received QAM symbol based, at least in part, on the plurality of distances calculated by the first de-mapper circuit. The receiver circuit may further include a decoder circuit to decode the set of encoded data bits recovered by the first de-mapper circuit. The second de-mapper circuit may identify a subset of the plurality of possible constellation points based on a result of the decoding and select a constellation point that is associated with the shortest distance of the plurality of distances.

    Abstract: An adaptive filter bank can be implemented on a PLC device to dynamically adapt to variations in notching requirements and the performance of the PLC medium. The PLC device can apply filter coefficients to one or more filter elements of the adaptive filter bank to generate one or more notched subcarriers in the PLC band. A performance measurement of one or more subcarriers in the PLC band can be determined and evaluated against corresponding performance measurement thresholds. For a given notched subcarrier, if the performance measurement of the corresponding subcarriers is not in accordance with the performance measurement threshold, updated filter coefficients for the filter element configured to generate the notched subcarrier can be determined based, at least in part, on the performance measurement of the one or more subcarriers. The filter coefficients of the filter element can then be updated using the updated filter coefficients.
