Abstract: A method of wireless communication by a receiver, includes predicting, with an artificial neural network, at each data block of a set of data blocks, a least complex set of demodulator parameters that will achieve a goal, based on features of a data block expected to be received. The method also includes dynamically selecting the least complex set of demodulator parameters, from multiple sets of demodulator parameters, based on the features of the data block expected to be received. The selecting occurring to prevent degradation of demodulation performance for each data block with the selected set of demodulator parameters for the data block, with respect to a more complex set of demodulator parameters.

Abstract: Methods, systems, and devices for wireless communications are described. Some wireless communications systems may support hybrid automatic repeat request (HARQ) process number indication for multi-cell scheduling. In some cases, a user equipment (UE) may receive first control signaling including one or more parameters associated with a HARQ process. Additionally, the UE may receive second control signaling indicating scheduling information associated with a set of component carriers (CCs), where the scheduling information includes one or more HARQ process identifier (HPID) offsets, each associated with a respective CC. In some cases, the UE may determine an HPID associated with each CC of the set of CCs based on the one or more parameters in the first control signaling and a respective HPID offset from the one or more HPID offsets in the second control signaling.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may transmit, to a network entity, capability information relating to a capability of the UE for processing unicast and multicast physical downlink shared channel (PDSCH) transmissions. The UE may receive configuration information that indicates unicast parameters for unicast PDSCH transmissions and multicast parameters for multicast PDSCH transmissions. The UE may receive at least one of one or more unicast PDSCH transmissions or one or more multicast PDSCH transmissions in a slot in a serving cell in accordance with a maximum soft buffer size associated with the UE and a maximum data rate associated with the UE, wherein the maximum soft buffer size and the maximum data rate are based at least in part on at least one of the unicast parameters or the multicast parameters. Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communications are described Techniques described may be utilized to avoid errors caused by resource allocation calculations, which may be indicated via higher layer signaling and/or determined within DCI. A base station may transmit downlink control information indicating resource allocation types to avoid errors. In other cases, the UE and/or base station may designate a particular resource block group size to avoid the potential errors. The UE and/or base station may calculate a number of resource blocks groups for a bandwidth part and allocate the size of the resource block group based on the calculation. The UE and/or base station may conduct a comparison between a bandwidth part size and a resource block group size to determine whether to designate a different resource block group size to avoid the errors. Similar techniques may be utilized in allocating resources for precoding resource block groups.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine an actual power delay profile (PDP) associated with a channel between the UE and a base station, wherein the actual PDP indicates an averaged power level of the channel over a period of time. The UE may determine whether a channel estimation mode switching event is satisfied. The UE may switch, based at least in part on the channel estimation mode switching event being satisfied, between a first channel estimation mode based at least in part on the actual PDP and a second channel estimation mode based at least in part on a template PDP. Numerous other aspects are described.

Abstract: A transmitter, such as a base station, identifies a potential collision between a first set of resources configured for a CORESET for a receiver and a second set of resources configured for a PT-RS for the receiver. The apparatus may determine whether colliding resources in the CORESET are configured/used for a control transmission or a data transmission. The apparatus punctures the PT-RS based on whether the colliding resources in the CORESET are configured/used for the control transmission (e.g., PDCCH). For example, the apparatus may puncture the PT-RS only for resource blocks of the CORESET colliding with the control transmission without puncturing the PT-RS over an entire set of the colliding resources configured for the CORESET. A receiver may similarly identify potential collisions and determine whether PT-RS will be punctured based on whether the colliding resources in the CORESET are configured/used for a control transmission or a data transmission.

Abstract: The present disclosure provides techniques for performing bit-level interleaving for orthogonal frequency-divisional multiplexing (OFDM) symbols across a plurality of code blocks. In some aspects, a transmitting device may dynamically switch between bit-level interleaving and tone-level interleaving for each OFDM symbol based on factors such as number of bits that are carried in each tone, size of each code block, the processing time requirements of the transmitting device and/or the receiving device, or the transmitting device preference.

An example method includes calculating a slot length for each UL slot of a plurality of UL slots, the slot length for each UL slot being associated with a plurality of rate matching output bits, each UL slot including a starting point for the plurality of rate matching output bits, the slot length for each UL slot being associated with a starting boundary, the plurality of UL slots being associated with at least one of a single TB or a single rate matching. The example method may include allocating one or more bits of the plurality of rate matching output bits for a modulation process. The example method may include refraining allocating at least one bit of the plurality of rate matching output bits for the modulation process, the at least one bit corresponding to UCI multiplexing.

Abstract: Methods, systems, and devices for wireless communications are described. Some examples of the described techniques provide for time-division multiplexing (TDM) modem envelope enhancements. A user equipment (UE) may receive, from a network entity, a message scheduling a transport block or multiple transport blocks in a downlink slot that immediately precedes one or more non-downlink slots (e.g., uplink (U), special(S), or flexible (F) slots) in a TDD slot configuration. The UE may receive the transport block or the multiple transport blocks in the downlink slot, and may process at least a portion of the transport block or the multiple transport blocks during one or more time intervals that occur after the downlink slot. The transport block may satisfy a per-slot transport block size threshold that is associated with a hybrid automatic repeat request (HARQ) processing timeline.

Abstract: Apparatuses and methods for received signal quality dependent PDCCH monitoring adaptation are described. An apparatus is configured to receive, from a network node, multiple SSS group configurations, and receive an indication of a first SSS group configuration from the multiple SSS group configurations based on a first received signal quality of the UE. The apparatus is also configured to monitor first PDCCH candidates associated with the first SSS group configuration. Another apparatus is configured to configure, for a UE, multiple SSS group configurations, and provide an indication of a first SSS group configuration from the multiple SSS group configurations based on a first received signal quality of the UE. The apparatus is also configured to provide a PDCCH for the UE in at least one PDCCH candidate of the first SSS group configuration.
