Abstract: Methods, systems, and devices for wireless communication are described. A transmitter, such as a user equipment and/or a base station, may perform polar coding to encode bits. The polar coding may be associated with a plurality of component channels associated with a polar code length. The transmitter may interleave the encoded bits. The transmitter may map the interleaved encoded bits to a modulation symbol. The interleaving and mapping of each encoded bit may be based on an asymmetry of a polar code construction. The transmitter may transmit the interleaved encoded bits based on the mapping.

Abstract: Method and apparatus for control signaling for SIC operation in 2-codeword operating mode. The apparatus transmits, to a network entity, a SIC capability indication comprising an indication that the UE supports a SIC operation for 2-CW allocation and an order of processing a first codeword and a second codeword. The apparatus monitors for an ACK to enable the SIC operation between the UE and the network entity. The apparatus receives downlink communication based on the SIC operation in response to receiving the ACK to enable the SIC operation. The apparatus may process the first codeword, within the downlink communication, transmitted based on a first MCS. The apparatus may cancel interference from the downlink communication based on the first codeword to obtain the second codeword, within the downlink communication, transmitted based on a second MCS.

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: 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: Aspects of the present disclosure relate to wireless communications, and more particularly, to techniques for mitigating interference caused by legacy reference signals from neighbor cells (e.g., LTE cell-specific reference signals) to non-legacy downlink transmissions in a serving cell (e.g., NR/5G PDSCH transmissions).

Abstract: Certain aspects of the present disclosure provide techniques for power savings for reduced capability devices. A method that may be performed by a user equipment (UE) includes receiving a shared bandwidth part (BWP) configuration and a group common BWP configuration. The group common BWP configuration indicates a group common BWP shared by a group of UEs, including the UE, having one or more common capabilities or a common UE type. The method includes communicating using the group common BWP based on the group common BWP configuration.

Abstract: This disclosure provides systems, methods and apparatuses that support channel state information (CSI) reporting techniques for secondary cell (SCell) activation. A user equipment (UE) may receive one or more medium access control-control elements (MAC-CEs) that indicate a secondary cell (SCell) activation command, an aperiodic tracking reference signal (AP-TRS) trigger, and an aperiodic channel state information (AP-CSI) report trigger. The network entity may signal the SCell activation command, the AP-TRS trigger, and the AP-CSI report trigger in the same MAC-CE or in separate MAC-CEs. The UE may receive and measure AP-TRS in accordance with the AP-TRS trigger indicated by the one or more MAC-CEs, and may perform measurements via an aperiodic channel measurement resource (AP-CMR) and an aperiodic interference measurement resource (AP-IMR) in accordance with the AP-CSI report trigger indicated by the one or more MAC-CEs. Accordingly, the UE may transmit an AP-CSI report associated with the measurements.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment may receive signaling that indicates one of a plurality of demodulation reference signal (DMRS) configurations for demodulating a downlink data channel in a slot or subslot. The UE may receive the signaling from a network entity, such as a base station, and the network entity may select the indicated DMRS configuration. The plurality of DMRS configurations may indicate whether DMRS combining is supported across the slot or subslot and a subsequent adjacent slot or subslot, and the plurality of DMRS configurations may include a configuration that is capable of indicating to the UE that a single DMRS is configured in the slot or subslot and is to be combined with a DMRS in a subsequent adjacent slot or subslot to demodulate the downlink data channel.

Abstract: Methods, systems, and devices for encoding and decoding are described. To encode a vector, an encoder allocates information bits of the vector to channel instances of a channel that are separated into groups. The groups may vary in size and allocation of the information bits is based on a base sequence of a given length. During decoding, a decoder assigns different bit types to channels instances by dividing a codeword into a plurality of groups and assigning bit types to channel instances of the plurality of groups using the base sequence.
