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: Aspects relate to techniques for enhancing sidelink scheduling information to include a priority assigned to a sidelink transmission. For example, a transmitting wireless communication device may receive sidelink scheduling information scheduling a sidelink transmission from a transmitting wireless communication device to a receiving wireless communication device. The sidelink scheduling information may further include a priority indicator associated with the sidelink transmission. The transmitting wireless communication device may then transmit the sidelink transmission to the receiving wireless communication device based on the scheduling information. The priority indicator may further facilitate hybrid automatic repeat request (HARQ) codebook construction on the sidelink and uplink for the transmission of acknowledgement information of the sidelink transmission.

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: 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: Aspects of the present disclosure provide systems and methods for informing a user equipment (UE) that which beam the UE is being served, for example, such as in relation to bandwidth part (BWP) switching in a non-terrestrial network (NTN). According to certain aspects, a network entity may transmit to a user equipment (UE) signaling indicating at least one BWP switch. The network entity provides, to the UE, an indication of a serving synchronization signal block (SSB) for the UE to use after the BWP switch.

Abstract: 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 use the preparation time to ensure that the BS sends a grant for the at least one transmission to the UE a sufficient amount of time before the at least one transmission is scheduled to occur to give the UE sufficient time to conduct the at least one UL transmission. In some examples, the BS determines the preparation time based on adjusting an uplink preparation time according to a defined value. In some examples, the BS determines the preparation time based on a subcarrier spacing (SCS) index. The BS may select the SCS index used to determine the preparation time from smallest of the SCS indexes configured for the different RF carriers.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a first indication of a default overlap resolution process for application by the UE on a plurality of overlapping transmissions. The plurality of overlapping transmissions may be collectively scheduled by one or more first downlink control information (DCI) messages received by the UE prior to a processing deadline for multiplexing the plurality of overlapping transmissions. The UE may determine, based on the processing deadline having passed, whether any one of the one or more first downlink control information messages includes a second indication of a transmission-specific overlap resolution process for application by the UE on a first two or more overlapping transmissions of the plurality of overlapping transmissions. The UE may perform a determined overlap resolution process including either the transmission-specific overlap resolution process or the default overlap resolution process.

Abstract: A user equipment (UE) determines an occurrence of a triggering event for providing negative acknowledgment (NACK) based feedback for a semi-persistent scheduling (SPS) transmission. The apparatus monitors for the SPS transmission. The apparatus transmits a NACK if the SPS transmission is not successfully received and refrains from sending an ACK if the SPS transmission is successfully received based on the occurrence of the triggering event for providing NACK based feedback. The base station determines an occurrence of a triggering event for a UE to provide NACK based feedback for an SPS transmission. The apparatus transmits the SPS transmission and determines that the UE successfully received the SPS transmission based on an absence of a NACK from the UE for the SPS transmission.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive, from a base station, a scheduling configuration for scheduling communications on a first component carrier. The scheduling configuration may indicate at least a first downlink control channel candidate on a second component carrier that is linked for control message repetition to a second downlink control channel candidate on one of the first component carrier or a third component carrier. The UE may then receive, from the base station and based on the scheduling configuration, at least one repetition of a control message in the first downlink control channel candidate or the second downlink control channel candidate, the control message scheduling a communication between the base station and the UE over the first component carrier. The UE may then transmit or receive the communication with the base station over the first component carrier.

Abstract: An apparatus for wireless communications includes a processor and a memory that includes instructions. The one or more processors are configured to execute the instructions to control reception, from a base station, of a first downlink signal using a first bandwidth amount that is based on a first frequency range associated with a particular signal transmitted by the base station. The one or more processors are further configured to execute the instructions to initiate transmission, to the base station, of a first uplink signal using a second bandwidth amount. The second bandwidth amount is less than the first bandwidth amount, and the second bandwidth amount is based on a second frequency range associated with an uplink channel.
