Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a wireless communication device may obtain synchronization with a primary cell of a wireless network. The wireless communication device may receive an indication to activate a secondary cell of the wireless network. The wireless communication device may receive a reference signal (RS) of the secondary cell. The wireless communication device may obtain synchronization with the secondary cell based at least in part on an offset between the RS of the secondary cell and a reference time of the primary cell, the reference time based at least in part on the synchronization with the primary cell. The wireless communication device may communicate via the secondary cell based at least in part on the synchronization with the secondary cell. Numerous other aspects are described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a sounding reference signal (SRS) configuration for SRS resources included an SRS resource set. The SRS configuration includes one or more first time domain parameters for the SRS resources. The UE may receive a dynamic indication of one or more second time domain parameters for the SRS resources. At least a subset of the one or more second time domain parameters are modified from the one or more first time domain parameters included in the SRS configuration. The UE may transmit, based at least in part on the one or more second time domain parameters, an SRS using the SRS resources. Numerous other aspects are described.

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: 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. Dynamic CB mapping may impact calculation of channel state information (CSI) metrics. A base station may transmit a physical downlink shared channel (PDSCH) based on a first dynamic CB mapping type in one or more slots. The base station may transmit a CSI reference signal (CSI-RS). A UE may receive the PDSCH and CSI-RS and calculate a channel quality indicator (CQI) and rank indicator (RI) based on the CRS assuming a second dynamic CB mapping type. The UE may transmit a CSI report including the CQI and the RI to the base station, which may assume the same second dynamic CB mapping type for the CQI and the RI.

Abstract: Aspects are provided which allow for a base station to transmit code blocks according to a frequency first per layer (FFPL) mapping, and for a UE to decode received code blocks according to the FFPL mapping. The base station maps a plurality of code blocks to multiple layers, where each of the code blocks is mapped to a plurality of resource elements initially by frequency and subsequently by time on only a single layer of the multiple layers. The base station then transmits data including the code blocks to a UE. Afterwards, the UE receives the data including the mapped code blocks in multiple layers from the base station, and the UE decodes the code blocks based on the mapping. Thus, improvements in link efficiency, reliability, and reduced power consumption compared to frequency first (FF) mapping approaches may be achieved.

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: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive configuration information for a sounding reference signal (SRS) resource set, the configuration information indicating a usage type for the SRS resource set associated with Doppler tracking and a configuration for one or more associated SRS resource identifiers. Some configuration parameters of the SRS resource set and the associated SRS resource identifiers can be dynamically reconfigured in order to allow adaptive SRS time domain pattern for enhanced Doppler parameter estimation and/or synchronization loop tracking, among other examples. The UE may transmit one or more SRSs in accordance with the configuration or dynamic reconfiguration information for the SRS resource set and the associated SRS resources based at least in part on receiving the configuration and/or reconfiguration information. Numerous other aspects are described.

Abstract: The apparatus, which may be a receiving device, is disclosed. The apparatus may receive at least one HARQ retransmission of at least one first bit. The HARQ retransmission may be associated with an MLC scheme including MSD. The MLC scheme may include a plurality of bits with the at least one first bit and at least one second bit. The apparatus may decode the at least one first bit of the MLC scheme based on the at least one HARQ retransmission. The apparatus may determine whether the at least one first bit of the MLC scheme is decoded successfully. The apparatus may decode, upon determining that the at least one first bit of the MLC scheme is decoded successfully, the at least one second bit of the MLC scheme based on at least one ARQ retransmission of the at least one second bit.
