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.

Channel state information (CSI) reporting techniques for secondary cell (SCELL) activation

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first network entity may receive, from a second network entity, an encoded communication. The first network entity may decode the encoded communication to obtain a communication via a list-based decoding scheme that includes respective parity check operations for each list of decoded information of a set of one or more lists of decoded information, the parity check operations being configured to be performed prior to a cyclic redundancy check (CRC) operation for the one or more lists of decoded information. Numerous other aspects are described.

Parity check for list-based decoding

The present disclosure provides self-decodable redundancy versions for a systematic code. An apparatus for wireless communications includes at least one processor coupled with a memory and comprising encoder circuitry configured to encode a set of information bits using a systematic code to generate an encoded bit stream with information bits and parity bits, and bit ordering circuitry configured to re-order bits in the encoded bit stream to distribute the information bits and the parity bits. The apparatus includes a transmitter configured to transmit the re-ordered bits in accordance with a radio technology via one or more antenna elements situated proximate the receiver.

Communication techniques with self-decodable redundancy versions (RVs) using systematic codes

Aspects of the present disclosure allow for more efficient rate matching by allowing a triggered A-ZP-CSI-RS set to support rate matching around multiple slots. Aspects of the present disclosure may allow a triggered A-ZP CSI-RS set to be applied to less than all scheduled PDSCH slots when DCI schedules PDSCH on multiple slots. Aspects of the present disclosure may extend CSI-RS resource mapping to span multiple adjacent slots. In another instance, aspects of the present disclosure allow a resource mapping configuration to indicate an initial symbol of a plurality of symbols spanning the plurality of slots for a respective A-ZP-CSI-RS resource. Doing so also allows a PDSCH transmission in a slot among the plurality of slots using a rate matching pattern associated with a set of A-ZP-CSI-RE resources to be received. In addition, aspects of the present disclosure can also add periodicity to A-ZP-CSI-RS resource set configuration.

Aperiodic zero power channel state information reference signal enhancement for multi-slot PDSCH rate matching

Various aspects of the present disclosure generally relate to wireless communication. Some aspects more specifically provide procedures and configurations used to perform, at a transmitter, probabilistic amplitude shaping (PAS) of quadrature amplitude modulation (QAM) communications using non-binary polar coding (NBPC). NBPC differs from binary polar coding (BPC) in that BPC uses a binary-input channel whereas NBPC uses a non-binary input channel. For example, while BPC uses a log likelihood ratio (LLR) with a single value corresponding to a given bit to be shaped, NBPC may use a probability mass function (PMF) to define or represent amplitude shaping target values. As another example, aspects use non-binary transformations, which reduce the number of passes to shape q bits from q passes (for BPC) to 1 pass (for NBPC).

Non-binary polar codes for probabilistic amplitude shaping

In some aspects, a user equipment (UE) may receive a message that includes an indication that a transmission configuration indicator (TCI) state switch for the UE is to be across a serving remote radio head (RRH) and a next RRH. The UE may adjust a tracking of the UE with respect to the serving RRH and the next RRH based at least in part on the indication. Numerous other aspects are described.

Indication of transmission configuration indicator state switching across remote radio heads

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may transmit, to a network node, an indication of a physical downlink control channel (PDCCH) processing unit (PPU) limit associated with the UE. The UE may receive configurations for a plurality of search space sets, wherein the plurality of search space sets includes one or more linked pairs of search space sets with linked PDCCH candidates for PDCCH repetition. The configurations of the one or more linked pairs of search space sets may be based at least in part on the PPU limit associated with the UE. Numerous other aspects are described.

Complexity handling for physical downlink control channel repetition

Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a demodulation reference signal (DMRS) and perform a filtering procedure on frequency-domain symbols of the DMRS to obtain a frequency-domain noise signal associated with the frequency-domain symbols. The UE may perform a spur detection procedure on the frequency-domain noise signal to detect one or more frequency spurs associated with the frequency-domain symbols. In addition, the UE may estimate a frequency of the frequency spurs. In some implementations, the UE may transmit information indicating spur parameters associated with the frequency spurs (e.g., including the estimated frequency) to a network entity. The UE may receive a control message indicating a rate matching pattern for subsequent communications, the rate matching pattern based on the spur parameters. The UE and the network entity may communicate according to the rate matching pattern.

Spur detection, estimation, and mitigation

Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive an indication of an antenna port mapping from a network entity. The antenna port mapping may be between a tracking reference signal and a corresponding reference signal, the antenna port mapping indicating a mapping of a tracking reference signal port to a plurality of reference signal antenna ports associated with the corresponding reference signal. The UE may receive a tracking reference signal via the tracking reference signal port based on the antenna port mapping. The UE may perform a channel measurement procedure using the tracking reference signal based on the mapping.

Port association with multiple demodulation reference signal (DMRS) ports

An example method may include receiving, from a second network node, SSB transmit power information for at least one carrier of a set of carriers, where the set of carriers may be associated with inter-band carrier aggregation, and where the SSB transmit power information may be indicative of an SSB transmit power or an SSB transmit power offset. The example method may further include determining a set of CSI-RS EPREs based on the SSB transmit power information for the at least one carrier, where the set of CSI-RS EPREs corresponds to a CSI-RS transmission in a first carrier of the set of carriers, where the first carrier is configured without SSB transmission.

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.

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.
