Abstract: This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for maintaining, between a user equipment (UE) and a component of a base station (BS), a mutual understanding of a set of linked physical downlink control channel (PDCCH) candidates if the UE selects to monitor a subset of the linked PDCCH candidates. In one aspect, the UE may monitor the subset of the linked PDCCH candidates, and the UE and the component of the BS may select a reference PDCCH candidate from which to define scheduling information in accordance with the UE monitoring the subset of the linked PDCCH candidates. In some examples, the UE and the component of the BS may select the reference PDCCH candidate in accordance with one or more mutually understood rules or procedures such that the UE and the component of the BS may select a same reference PDCCH candidate.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive configuration information indicating a power offset, per resource block, between one or more first resource blocks to carry acknowledgement/negative acknowledgement feedback and one or more second resource blocks in a common interlace. The UE may transmit, using the power offset and using a transmission power that depends on whether a downlink pathloss value is indicated in the configuration information, a physical sidelink feedback channel transmission in the one or more first resource blocks and the one or more second resource blocks. Numerous other aspects are described.

Abstract: Disclosed are techniques for environment sensing. In an aspect, a transmitter base station determines a configuration for a radio frequency (RF) sensing signal, the configuration determined based at least in part on coordination among a plurality of base stations, and transmits the RF sensing signal to at least one receiver base station based on the configuration. In an aspect, a receiver base station receives a configuration for an RF sensing signal, the configuration determined based at least in part on coordination among a plurality of base stations, receives, from at least one transmitter base station, the RF sensing signal, and detects at least one target object based, at least in part, on reception of the RF sensing signal.

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.

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.
