Wireless communications systems and methods related to wireless communications in a system are provided. A wireless communication device may compute a plurality of log-likelihood ratios (LLRs) based on a received communication signal. At least a first LLR and a second LLR of the plurality of LLRs represent the same first bit in the communication signal. The wireless communication device may combine the first LLR and the second LLR to decode the first bit and transmit a report indicating channel information. The channel information may be based at least in part on the plurality of LLRs before the combining of the first and second LLRs.

Channel information based on uncombined log likelihood ratios (LLRS)

A method of wireless communication performed by a user equipment (UE) includes receiving, from a network node, a first message configuring a group of component carriers that includes a primary component carrier and one or more secondary component carriers. The method also includes receiving, from the network node, a second message configuring a number of repetitions of a physical uplink control channel (PUCCH) transmission. The method further includes transmitting, to the network node, each repetition of the PUCCH transmission via the primary component carrier or one of the one or more secondary component carriers in accordance with the number of repetitions, each repetition being transmitted on only the primary component carrier in accordance with the number of repetitions being greater than one, and each repetition being transmitted on either the primary component carrier or the secondary component carrier in accordance with the number of repetitions being equal to one.

Physical uplink control channel (PUCCH) repetition across multiple component carriers

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a configuration of a first hybrid automatic repeat request acknowledgement (HARQ-ACK) codebook and a second HARQ-ACK codebook, wherein the configuration indicates that physical uplink control channel (PUCCH) carrier switching is enabled for at least one of the first HARQ-ACK codebook or the second HARQ-ACK codebook. The UE may receive an indication of a PUCCH carrier switch for the at least one of the first HARQ-ACK codebook or the second HARQ-ACK codebook. The UE may receive a downlink communication associated with the at least one of the first HARQ-ACK codebook or the second HARQ-ACK codebook. The UE may transmit HARQ feedback a target PUCCH carrier based at least in part on the indication of the PUCCH carrier switch. Numerous other aspects are described.

Physical uplink control channel carrier switch with multiple hybrid automatic repeat request acknowledgement codebooks

Techniques described provide dependent procedure operation configured for avoiding or mitigating one or more aspect of the impact on the dependent procedure of cancelling an uplink transmission. One or more attributes (e.g., a transmission indication attribute) associated with a cancelled uplink transmission may be designated for dependent procedure operation, such as for indicating whether the cancelled uplink transmission is considered either as having been transmitted or not having been transmitted. The one or more attributes associated with a cancelled uplink transmission designated for dependent procedure operation may be based upon whether the cancelling the first uplink transmission is a fast cancellation or is a slow cancellation. The designation of a transmission indication attribute for dependent procedure operation may correspond to the dependent procedure and/or its operation. Other aspects and features are also claimed and described.

Techniques for dependent procedure operation impacted by link cancellation

A method of wireless communication includes determining, by a user equipment (UE), that one or more symbols scheduled for reporting a hybrid automatic repeat request (HARQ) acknowledgement (HARQ-ACK) to a base station for a semi-persistent scheduling (SPS) physical downlink shared channel (PDSCH) transmission include at least one invalid symbol, wherein the one or more symbols are located in a first slot or sub-slot; selecting, by the UE, based on one or more parameters of the SPS PDSCH transmission, a second slot or sub-slot, subsequent to the first slot or sub-slot, for sending a delayed HARQ-ACK for the SPS PDSCH transmission; and sending, by the UE to the base station, the delayed HARQ-ACK for the SPS PDSCH transmission on the second slot or sub-slot.

Delayed HARQ-ACK report for SPS

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a signal associated with a communication channel. The UE may transmit a channel quality indicator (CQI) report comprising one or more CQI values based at least in part on a determined number of bits used to represent the one or more CQI values. The number of bits used to represent the one or more CQI values is based at least in part on a number of the one or more subbands. Numerous other aspects are described.

Dynamic quantization of channel quality information

Methods, systems, and devices for wireless communications are described. For instance, a network entity may transmit, to a user equipment Transmission (UE), control signaling indicating that the UE is to provide feedback corresponding to a set of feedback process identifiers for at least one component carrier. The network entity may transmit, to the UE, a cancellation indication Feedback Message that cancels a scheduled uplink transmission in which the UE is scheduled to provide feedback data corresponding to a subset of the set of feedback process identifiers. The network entity may transmit, to the UE, a control message scheduling the UE to transmit the feedback data corresponding to the subset of the set of feedback process identifiers (e.g., based on the cancellation indication). The UE may transmit, to the network entity, a feedback message including the feedback data for the subset based on the control message.

Feedback based on indicated feedback process identifiers

Methods, systems, and devices for wireless communications are described. A user equipment (UE) may generate feedback messages according to a feedback codebook according to a feedback scheme indicating whether the UE is to include, or exclude, feedback information for physical downlink shared channels (PDSCHs) occurring prior to a bandwidth part (BWP) switch. For example, the UE may determine whether to include feedback information for any PDSCHs that occur prior to an uplink BWP switch for a UE that supports cell switching based on the cell in which the uplink BWP switch occurs, the cell in which the feedback message is scheduled for transmission (e.g., the same cell in which the PDSCHs occur, or a different cell), and a mode of PUCCH cell switching (e.g., dynamic or semi-static). The UE may also determine whether to send retransmissions of feedback information after a BWP switch.

Spectrum sharing between networks

Data aware precoding techniques are disclosed. A transmitter may apply a precoder function to payload data to obtain a precoded data transmission. The precoder function may include a first portion, e.g., based on a channel measurement, and a second portion, e.g., based on data for transmission. The transmitter may transmit the precoded data transmission. A receiver may receive a precoded data transmission that is precoded based on a channel measurement and based on data comprised in the data transmission. The receiver may decode the precoded data transmission based on the channel measurement and the data comprised in the data transmission.

Data based precoding techniques

A method, an apparatus, and a computer program product for wireless communication are provided. The apparatus may receive a configuration indication for a common uplink portion of a wireless communication structure. The apparatus may configure the common uplink portion based at least in part on the configuration indication. The apparatus may transmit a communication in the common uplink portion configured according to the configuration indication.

Techniques and apparatuses for configuring a common uplink portion in new radio

Methods, systems, and devices for wireless communications are described for controlling multiplexing of a reference signal on an uplink shared channel (UL-SCH). In an implementation, a user equipment (UE) may time division multiplex (TDM) a demodulation reference signal (DMRS) with other signaling across symbol periods of one or more allocated resource blocks. The UE may map the DMRS to resource elements of one or more symbol periods within the allocated resource blocks. The UE may then map uplink control information (UCI) to one or more symbol periods different than the symbol periods of the DMRS mapping. In some cases, the DMRS, UCI, or both may be frequency interleaved with UL-SCH data for the allocated resource blocks. The UE may generate and transmit an uplink waveform for transmission within the allocated resources of the uplink shared channel.
