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.

Controlling multiplexing of a reference signal on an uplink shared channel

A base station (BS) may determine (estimate) a preparation time for at least one uplink (UL) transmission by a user equipment (UE) on at least one radio frequency (RF) carrier. The BS may determine the preparation time so that the BS will send a grant for the at least one transmission to the UE a sufficient amount of time (based on the estimated preparation time) before the at least one transmission is scheduled to occur to enable the UE to conduct the at least one UL transmission on a selected one of the RF carriers or on both RF carriers. The BS may select the longest preparation time from the preparation times of different RF carriers. The BS may select the subcarrier spacing (SCS) index from the SCS indexes for different RF carriers that provides a longer preparation time. The BS may add a defined value to a preparation time.

Determining transmission preparation time for wireless communication on at least one carrier

Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a message scheduling a multi-repetition uplink transmission to a base station. The UE may generate a protocol data unit (PDU) comprising filler data for the multi-repetition uplink transmission based at least in part on a quantity of data in a buffer for transmission to the base station failing to satisfy a threshold. The UE may transmit a repetition of the multi-repetition uplink transmission based at least in part on determining that the repetition overlaps with a feedback message scheduled for transmission to the base station, the repetition comprising the PDU multiplexed with the feedback message. The UE may suppress a transmission of one or more additional repetitions of the multi-repetition uplink transmission that do not overlap with the feedback message based at least in part on the PDU comprising the filler data.

Feedback multiplexing for uplink transmission with repetition skipping

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a base station may transmit a plurality of physical downlink control channel (PDCCH) communications in a same PDCCH monitoring occasion in a first cell, and may transmit a plurality of physical downlink shared channel (PDSCH) communications in at least one of the first cell or a second cell. Each of the PDCCH communications schedules a respective PDSCH communication of the plurality of PDSCH communications. A PDCCH communication, of the plurality of PDCCH communications, includes an indication of a counter downlink assignment index that is based at least in part on a combination of a starting symbol and a cell in which an associated PDSCH communication is to be transmitted, a cell index of the cell in which the associated PDSCH communication is to be transmitted, and the PDCCH monitoring occasion. Numerous other aspects are provided.

HARQ feedback reporting for cross-carrier scheduling

This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media for resolving collisions between deferred uplink transmissions based on priority. A user equipment (UE) receives a first semi-persistent scheduling (SPS) configuration including an indication of resources for acknowledgment (ACK) reporting as uplink control information (UCI), the first SPS configuration indicating a first priority level. The UE receives a second signaling indicating a second priority level for a second transmission, the second priority level being higher than the first priority level. The UE defers a first UCI transmission according to the first SPS configuration during one or more downlink slots to a first uplink capable slot. The first UCI transmission in the first uplink capable slot collides with the second transmission. The UE transmits the second transmission in the first uplink capable slot based on the second priority level being higher than the first priority level.

Deferral of SPS HARQ-ACK with different priorities

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may append one or more bits of a scheduling request (SR), having a first priority and in a first physical uplink control channel (PUCCH) resource associated with a first format, to one of more bits of a hybrid automatic repeat request acknowledgement (HARQ-ACK), having a second priority and in a second PUCCH resource associated with a second format, to form a multiplexed SR and HARQ-ACK. The UE may select a PUCCH resource, from a plurality of high priority PUCCH resources, based at least in part on a payload size of the multiplexed SR and HARQ-ACK. The UE may transmit, to a network node, the multiplexed SR and HARQ-ACK using the selected PUCCH resource. Numerous other aspects are described.

Multiplexing hybrid automatic repeat request acknowledgement and scheduling request with different priorities and physical uplink control channel formats

A wireless device determines a discontinuous reception (DRX) pattern for sidelink communication and performs sidelink activity within a DRX ON duration of the DRX pattern. A wireless device may transmit a sidelink discovery message including information about a DRX pattern of the first wireless device and may monitor for sidelink communication based on the DRX pattern. A second wireless device may receive a sidelink discovery message from the first wireless device including information about a DRX pattern of the first wireless device and may exchange sidelink communication with the first wireless device based on the DRX pattern.

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may transmit a configured grant (CG) status indication that indicates a status of at least one CG instance associated with an uplink CG configuration, wherein the status indicates whether a CG communication is to be transmitted during the at least one CG instance. The UE may transmit one or more CG communications based at least in part on the status of the at least one CG instance. Numerous other aspects are described.

Status indications for uplink configured grant instances

Aspects of the present disclosure provide techniques for communicating channel state information (CSI) reports. In some aspects, downlink resources can be monitored for reception of downlink signaling, a CSI report can be generated based on the reception of the downlink signaling, where the CSI report indicates CSI for each of multiple sub-bands of the downlink resources, and the CSI report can be transmitted with hybrid automatic repeat request (HARQ) acknowledgement or negative acknowledgement (ACK/NACK) feedback associated with the downlink signaling to facilitate retransmission with improved block error rate (BLER). In some aspects, a base station receiving the CSI report, or otherwise based on uplink signals, can determine transmission parameters for retransmission to facilitate the improved BLER.

Techniques for providing channel quality feedback for enhanced reliability in wireless communications

Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive an indication of conflict conditions for identification of conflicts between uplink feedback messages and a communication frame structure, and may receive a downlink message within a set of semi-persistent downlink resources. The downlink message may be associated with a first uplink resource for transmitting a feedback for the downlink message, where the first uplink resource is included within a subband full-duplex (SBFD) slot that includes one or more uplink subbands. The UE may then transmit the feedback message via the first uplink resource or a second uplink resource that is deferred relative to the first uplink resource based on whether feedback deferral for the downlink message is triggered in accordance with the one or more conflict conditions the second uplink resource is included within a second slot that is subsequent to the subband full-duplex slot.
