Abstract: Apparatus, methods, and computer program products for wireless communication are provided. An example method may include receiving, from a network node, a first stage downlink control information (DCI) associated with a second stage DCI, where the first stage DCI comprises information regarding a set of time and frequency resources associated with a physical downlink shared channel (PDSCH), and where the second stage DCI includes decoding information associated with the PDSCH. The example method may further include receiving, from the network node based on the information regarding the set of time and frequency resources, a transmission including the second stage DCI and the PDSCH, where the second stage DCI is multiplexed with the PDSCH, and where the second stage DCI is overlapping in time with the PDSCH. The example method may further include decoding the PDSCH based on the second stage DCI.

Abstract: This disclosure provides systems, methods, and apparatus, including computer programs encoded on computer-readable media, for implementing signaling for indicating a scheduled full duplex (FD) uplink (UL) and downlink (DL) traffic scheduling combination for differentiation of FD traffic. In some aspects, a BS may transmit a downlink control information (DCI) message that includes an indication of the scheduled FD UL and DL traffic scheduling combination. The FD UL and DL traffic scheduling combination may identify scheduled UL and DL transmissions for FD mode operation. The UE may receive the DCI message and identify the scheduled FD UL and DL traffic scheduling combination. In some aspects, the BS may provide a DCI message to the UE that indicates whether a DL transmission is being scheduled that at least partially overlaps with a scheduled UL transmission. The UE may initiate a power save mode based on the received DCI message.

Certain aspects provide a method for wireless communication by a first user equipment (UE). The method generally includes receiving, from a second UE, one or more sidelink data messages over a first subchannel during a time period having a duration of a first number of slots that is greater than one and transmitting, to the second UE, over a plurality of resource blocks of a sidelink feedback channel resource of a first feedback channel occasion of a set of periodically occurring feedback channel occasions, a first feedback message associated with the one or more sidelink data messages, wherein the first feedback message indicates a plurality of feedback bits comprising one or more feedback bits associated with the one or more sidelink data messages.

Abstract: PDCCH/PDSCH multiplexing with rank adaptation is described. An apparatus is configured to receive a PDSCH transmission multiplexed with a PDCCH transmission that includes information to schedule the PDSCH. The PDCCH has a first rank, the PDSCH has a second rank, and both share a DMRS(s). The apparatus is configured to decode the PDSCH using a channel estimation for the PDSCH and the second rank of the PDSCH that is based on the shared DMRS indication. Another apparatus is configured to encode a PDSCH transmission multiplexed with a PDCCH transmission that includes information to schedule the PDSCH. The PDCCH has a first rank, the PDSCH has a second rank, and both share a DMRS(s). The apparatus is configured to provide, for a UE, the PDSCH transmission multiplexed with the PDCCH transmission that schedules the PDSCH and a shared DMRS indication indicative of the shared DMRS(s).

Abstract: Aspects described herein relate to receiving, from a network node, downlink control information (DCI) including a parameter having a value indicating whether uplink control information (UCI) is to be multiplexed with an uplink control channel or an uplink shared channel, multiplexing, based on the value, UCI with one of the uplink control channel or the uplink shared channel, and transmitting one of the uplink control channel or the uplink shared channel multiplexed with the UCI. Other aspects relate to generating the DCI and demultiplexing the UCI.

Abstract: A method for wireless communication at a UE includes forming a first hybrid automatic repeat request acknowledgement (HARQ-ACK) part and a second HARQ-ACK part associated with a HARQ-ACK payload in accordance with a transformation scheme. The HARQ-ACK payload includes HARQ feedback for each one of a group of downlink transmissions. The method also includes separately encoding the first HARQ-ACK part and the second HARQ-ACK part. The method further includes multiplexing the encoded first HARQ-ACK part and the encoded second HARQ-ACK part on a physical uplink shared channel (PUSCH). The method still further includes transmitting, to the network node via the PUSCH, the multiplexed first HARQ-ACK part and second HARQ-ACK part.

Abstract: A method of wireless communication by a user equipment (UE) includes converting a block of hybrid automatic repeat request acknowledgment (HARQ-ACK) bits from an original HARQ-ACK codebook into a partition, a number of partitions for a number of blocks corresponding to quantized HARQ-ACK bits. The method also includes transforming the quantized HARQ-ACK bits into a two part HARQ-ACK payload. The method further includes separately encoding a first part and a second part of the two part HARQ-ACK payload. The method also includes transmitting, to a network node, the encoded first part and the encoded second part.

Abstract: Wireless communications systems and methods are provided. A method of wireless communication may include performing a first listen-before-talk (LBT) procedure associated with a channel, wherein a channel occupancy time (COT) for the channel is acquired based on the first LBT being successful, communicating a first communication signal in a first link direction during the COT, switching from the first link direction to a second link direction different from the first link direction, and communicating after the switching, a second communication signal in the second link direction without performing a second LBT.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first user equipment (UE) may receive, from a second UE, a first message that indicates a sidelink bandwidth part (BWP) switch, for the second UE, to a first sidelink BWP, where the first message includes an indication of the first sidelink BWP and a first sidelink resource pool in the first sidelink BWP. The first UE may transmit, to the second UE, a second message that confirms the sidelink BWP switch for the second UE. The first UE may receive, from the second UE, a third message that activates the sidelink BWP switch, for the second UE, to the first sidelink BWP. Numerous other aspects are described.
