Abstract: Methods, systems, and devices for wireless communication are described. To encode a vector of bits using a polar code, an encoder may allocate information bits of the vector to polarized bit-channels associated with a channel (e.g., a set of unpolarized bit-channels) used for a transmission. In some cases, the polarized bit-channels may be partitioned into groups associated with different values of some associated reliability metric (s). The information bits may be allocated to the polarized bit-channels based on the reliability metrics of the different polarized bit-channels and the overall capacity of a transmission. That is, the bit locations of a transmission may depend on the reliability metrics of different polarized bit-channels and the overall capacity of the transmission. To facilitate puncturing, the overall capacity of the transmission may be adjusted and the unpolarized bit-channels may be partitioned into polarized bit-channels based on the adjusted capacity.

Abstract: Decoding and encoding methods, systems, and devices for wireless communication are described. One method may include receiving a codeword over a wireless channel, the codeword being encoded using a polar code, identifying a set of repeated bit locations in the received codeword, and identifying a set of bit locations of the polar code used for information bits for the encoding. The set of bit locations may be determined based at least in part on recursively partitioning bit-channels of the polar code for each stage of polarization and assigning portions of a number of the information bits to bit-channel partitions of each stage of polarization based on a mutual information transfer function of respective aggregate capacities of the bit-channel partitions. The method may also include decoding the received codeword according to the polar code to obtain an information bit vector at the set of bit locations, and other aspects and features.

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.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may support dynamic clock switching within a transmission time interval (TTI) to allow for more efficient and flexible processing within the TTI. In particular, a user equipment (UE) may be configured to use multiple clock speeds for processing signals within a TTI, and the UE may determine a clock speed to use for processing data within a TTI based on control information received from a base station. For example, the UE may determine an amount of time available for processing data based on the control information received from the base station, and the UE may adjust its clock speed to finish processing the data in the determined amount of time.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may transmit an indication of a physical downlink control channel (PDCCH) monitoring capability that indicates an amount of time between two consecutive PDCCH monitoring windows, a number of slots to be included in a PDCCH monitoring window, and a number of consecutive symbols in a slot to be associated with PDCCH monitoring. The UE may receive a PDCCH monitoring configuration that is based at least in part on the PDCCH monitoring capability. Numerous other aspects are described.

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 that support overlapping physical downlink control channel (PDCCH) candidate thresholds. In some examples, a user equipment (UE) may determine, for each subcarrier spacing (SCS) configuration of a set of SCS configurations, a threshold number of overlapping PDCCH candidates within a time interval. The UE may receive, from a base station, signaling indicating one or more PDCCH monitoring configurations. In some examples, the UE may monitor the PDCCH for control information according to the one or more PDCCH monitoring configurations and a number of overlapping PDCCH candidates, where the number of overlapping PDCCH candidates may satisfy (e.g., be less than or equal to) the threshold number of overlapping PDCCH candidates.

Abstract: Methods, systems, and devices for wireless communications are described. In some wireless communications systems, a user equipment (UE) and a network entity may utilize multi-port mobility reference signals to assist with spatial based mobility procedures. The UE may receive a reference signal that is associated with multiple antenna ports. The UE may measure a multi-dimensional channel response based on the reference signal. The multi-dimensional channel response may be associated with measured channel metrics corresponding to the multiple antenna ports. The UE may transmit a report that includes a channel measurement vector based on the multi-dimensional channel response. The channel measurement vector may indicate multiple measured channel metrics for one or more dimensions of the multi-dimensional channel response. The network entity may transmit a message that indicates one or more metrics associated with mobility management for the UE based on the report that indicates the channel measurement vector.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may measure a first energy level of a demodulation reference signal (DMRS). The UE may measure a second energy level of at least one of a tracking reference signal (TRS) or a synchronization signal block (SSB). The UE may determine, based at least in part on the first energy level and the second energy level, a DMRS signal-to-noise ratio (SNR). The UE may perform, based at least in part on the DMRS SNR, channel estimation for a physical channel associated with a communication to determine an estimated channel. The UE may perform, based at least in part on the estimated channel, demodulation processing for the communication. Numerous other aspects are described.
