Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive an indication of a codebook type for transmitting hybrid automatic repeat request (HARQ) feedback by the UE to a second device (e.g., a network device, a satellite, or a base station). The indication of the codebook type may indicate a HARQ feedback transmission configuration, such as a static HARQ feedback transmission configuration. The HARQ transmission configuration may be associated with a one bit or two bit HARQ codebook. The UE may receive a scheduled downlink shared channel transmission, and attempt to decode the received downlink shared channel transmission. The UE may transmit (or refrain from transmitting) the HARQ feedback based on the decoding of the scheduled downlink shared channel transmission and in accordance with the feedback mode.

Abstract: Different sets of downlink control information (DCI) fields may be configured for DCI that includes an indication to trigger bandwidth part switching at a user equipment (UE). For example, a UE may receive DCI that triggers the UE to switch operation from a first bandwidth part to a second bandwidth part. The UE may also identify a set of transformable DCI fields and a set of non-transformable DCI fields within the DCI. The UE may then determine updated content of the DCI for application to the second bandwidth part based on whether DCI fields are included in the set of transformable or the set of non-transformable fields. In some cases, the UE may identify a null assignment in the received DCI and may switch its operation from the first bandwidth part to the second bandwidth part based on the null assignment.

Abstract: Methods, apparatuses, and computer-readable storage medium for rate matching for TBoMS are provided. 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: A new radio (NR) bit prioritization procedure that may be executed by a UE and a base station is disclosed, resulting in transmission and reception of modulation symbols having prioritized bits. For example, a transmitter may encode a code block using low-density parity-check code to generate a stream of encoded bits. The transmitter may arrange the encoded bits in one or more modulation symbols according to a relative priority of the encoded bits. The highest priority bits may be located in the most significant bits of the modulation symbol, and therefore be less likely to experience errors. A receiver may receive the modulation symbols and reorder the encoded bits according to the coding scheme based on the relative priority prior to decoding the encoded bits. The prioritization of the bits within the modulation symbols may provide improved block error rates over sequential mapping of encoded bits to symbols.

Abstract: Certain aspects of the present disclosure provide techniques for cell measurement scheduling mode selection. According to certain aspects, a method for wireless communications by a user equipment (UE), generally includes selecting a first scheduling mode for performing cell measurements while the UE is in an idle state, in response to detecting at least one first triggering condition based on a comparison of a serving cell measurement to one or more neighbor cell measurements and performing cell measurements in accordance with the first scheduling mode, wherein the UE performs cell measurement more frequently when the first scheduling mode is selected than when a second scheduling mode is selected.

Abstract: Bandwidth part (BWP) switching may benefit a wireless communications system. Such BWP switching may include indication of one or more timing parameters used for time domain resource allocation. For example, the timing parameters may be indicated based on an index to a look-up table (e.g., a bit field in a control transmission). In some cases, one or more tables may be configured for a given BWP, and different tables may contain a different number of rows. The size of the bit field indexing the table may in turn depend on the number of rows. When switching from a first BWP to a second BWP, the size of the bit field may be based on the table of the first BWP, but the bit field may index the table of the second BWP. Techniques supporting improved timing parameter management during BWP switching are discussed herein.

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: Methods, systems, and devices for wireless communications are described that provide for receive chain selection at a user equipment (UE) with efficient switching between a reduced number of receive chains and an increased number of receive chains for downlink communications based on conditions at the UE. A UE may adaptively adjust the number of active receive chains based on downlink grant activity, channel conditions, network parameters, or any combinations thereof. An estimator block at the UE may determine to adjust the number of receive chains based on a number of downlink grants within one or more time periods. In some cases, grants for an amount of data that exceeds a threshold may be qualified in order to be counted at the estimation block. Further, a transient state may be provided where the UE may maintain a higher number of active receive chains until UE feedback is provided.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a first slot format configuration for a first serving cell for a set of transmission time intervals (TTIs) including a first TTI and receive a second slot format configuration for the first serving cell for the first TTI which is different from the first slot format configuration. The UE may determine, based on priorities of the slot format configurations, a first communication direction for the first serving cell for the first TTI. The UE may identify, for a second serving cell for the first TTI, a second communication direction indicated by one or more slot format configurations for the second serving cell. The UE may determine whether to communicate on the second serving cell for the first TTI according to the one or more slot format configurations for the second serving cell.

Abstract: The present disclosure relates to methods and devices for wireless communication including an apparatus, e.g., a UE and/or a base station. The apparatus may measure a RSRP of a CRS for each of a plurality of neighboring cells. The apparatus may also calculate an interference strength of each of the plurality of neighboring cells based on the RSRP measurement of the CRS for each of the plurality of neighboring cells. Additionally, the apparatus may compare a PDSCH demodulation performance of the UE based on rate matching for a CRS offset associated with each of the plurality of neighboring cells with the PDSCH demodulation performance of the UE based on skipping the rate matching for the CRS offset. The apparatus may also transmit a request for the rate matching or skipping the rate matching for the CRS offset based on the comparison of the PDSCH demodulation performance of the UE.
