Abstract: In a wireless communication system, dynamic changes of a code block (CB) to resource element (RE) mapping type may improve decoding performance in some scenarios. A user equipment may provide an indication of a preferred CB mapping type. A base station may transmit a physical downlink shared channel (PDSCH) based on a first dynamic CB mapping type in one or more slots. A UE may receive the PDSCH and determine a second CB mapping type that is preferred by the UE based on a metric. The UE may transmit an indicator of the second CB mapping type, for example, as a one-bit or two-bit indicator, which may be coupled with a channel state information (CSI) report or signaled in uplink control information (UCI) independently from a CSI report. The base station may consider the indicator when selecting a new dynamic CB mapping type for the UE.

Abstract: Methods, systems, and devices for wireless communications are described. The described techniques support blind common phase error (CPE) and residual carrier frequency offset mitigation. Generally, the described techniques provide for blind CPE mitigation at a receiving device without a phase tracking reference signal (PTRS) associated with less overhead and improved performance as compared to use of a PTRS to mitigate CPE. A receiving device may receive a shared channel message in a scheduled shared channel allocation in accordance with a PTRS configuration that omits a PTRS allocation based on a capability of the receiving device to apply blind CPE mitigation for shared channel receptions. In some examples, with a single DMRS symbol allocation, blind CPE mitigation for each subsequent data symbol of a shared channel message may be based on the blind CPE estimation for the previous symbol, which may enable robust mitigation of a residual carrier frequency offset.

Abstract: Methods, systems, and devices for wireless communications are described. In some cases, a user equipment (UE) may transmit a control message indicating semi-persistent (SP) resources for multiple wireless devices scheduling within a set of resource reservation periods. The UE may measure one or more channel conditions of a channel during a first resource reservation period of the set of resource reservation periods, the channel associated with the SP resources for the multiple wireless devices. Additionally, the UE may adapt a compression parameter of one or more signals to be transmitted to the multiple wireless devices during the first resource reservation period based on the one or more channel conditions and may transmit, to the multiple wireless devices, one or more compressed signals generated based on the compression parameter and the one or more signals.

Abstract: The base station may transmit to the UE, a first part and a second part of a PDSCH. The UE may decode the second part of the PDSCH. The first part of the PDSCH may be associated with a higher MCS than the second part of the PDSCH. The UE may estimate at least one of an ICI or a CPE associated with the PDSCH based on the decoding of the second part of the PDSCH. The UE may decode the first part of the PDSCH based on the decoding of the second part of the PDSCH. Decoding the first part of the PDSCH based on the decoding of the second part of the PDSCH may include correcting for the at least one of the ICI or the CPE associated with the PDSCH.

Abstract: A base station may configure a Doppler tracking sounding reference signal (SRS) resource set with different time gaps between SRS resources of the Doppler tracking SRS resource set. However, factors influencing an optimal time gap for uplink Doppler parameter estimation may change over time and may depend on a Doppler parameter to be estimated. Therefore, parameters of an aperiodic Doppler tracking SRS resource set configuration may become suboptimal for estimating uplink Doppler parameters. Some techniques and apparatuses described herein enable dynamic parameter adaptation for aperiodic Doppler tracking SRS resource sets. The base station may dynamically adapt one or more parameters for an aperiodic Doppler tracking SRS resource set to modify a time gap and/or a number of resources or symbols to be transmitted for an aperiodic Doppler tracking SRS resource set. The base station may transmit downlink control information that indicates the one or more parameters.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may transmit one or more messages that indicate a capability of the UE to support the reception of demodulation reference signals (DMRS) and time drift reference signals (TDRS) according to one or more signaling patterns configured by the network. The UE may then receive one or more control messages that indicate a first signaling pattern for one or more DMRSs and a second signaling pattern for one or more TDRSs, where the first signaling pattern corresponds to or is based on the second signaling pattern. The UE may receive a downlink shared channel multiplexed with the one or more DMRSs according to the first signaling pattern and may receive the downlink shared channel multiplexed with the one or more TDRSs according to the second signaling pattern.

Abstract: Methods, systems, and devices for wireless communications are described. In some systems, a user equipment (UE) may measure a received power of one or more reference signals, such as channel state information (CSI) reference signals (CSI-RSs) or synchronization signal blocks (SSBs), transmitted by a base station for a beam management procedure. The UE may determine a set of channel statistics associated with a channel used by the base station to transmit the one or more reference signals based on performing the beam management procedure. The UE may transmit a report to the base station, the report including at least an indication of the received of the one or more reference signals and the set of channel statistics. The base station may select a beam or a channel for communication with the UE based on at least the indication of the received power and the set of channel statistics.
