Abstract: Methods, systems, and devices for wireless communications are described. A first base station may communicate during asynchronous slots in accordance with a set of communication parameters determined from a handshake procedure performed with a second base station. For example, based on a change to a slot type of a slot to an asynchronous slot, the first base station and the second base station may perform the handshake procedure to determine the set of communication parameters and may communicate one or more messages during the slot in accordance with the set of communication parameters. Additionally, or alternatively, a user equipment (UE) may transmit a sounding reference signal (SRS) associated with a transmission configuration indicator (TCI) state based on a slot type of a first slot in which the UE transmits the SRS and a reference signal received in a second slot having the slot type.

Abstract: Methods, systems, and devices for wireless communications are described. A network node and a user equipment (UE) may establish a connection between the UE and the network node of a non-terrestrial network. The UE may receive, from the network node and based on a type of orbit around Earth of the network node, a first value or the first value and a second value associated with a position or a velocity of the network node relative to a terrestrial-based reference. The UE and the network node may communicate based on the position or the velocity of the network node, or both. In some cases, the position or the velocity of the network node is based on an altitude of the network node, the first value, the second value, and a third value.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, on a first carrier having a first subcarrier spacing (SCS), a scheduling indication via a physical downlink control channel (PDCCH) scheduling a downlink transmission on a second carrier having a second SCS. The UE may process the downlink transmission on the second carrier based at least in part on a delay between the PDCCH and the scheduled downlink transmission and a timing threshold having a basic term and an adjustment term. For example, the basic term may be based at least in part on a minimum delay between the PDCCH and the scheduled downlink transmission, and the adjustment term may be based at least in part on a processing time due to a difference between the first SCS and the second SCS. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) supporting full duplex communications may determine that a set of downlink messages to be transmitted from a base station to the UE overlaps in time with a set of uplink messages to be transmitted from the UE. Accordingly, the UE may determine a downlink transmission power adjustment value for the set of downlink messages. In some examples, the base station may indicate the downlink transmission power adjustment value to the UE via radio resource control (RRC) signaling, a downlink control information (DCI) message, or both. The UE may transmit the set of uplink messages while simultaneously receiving the set of downlink messages with a transmission power that corresponds to the downlink transmission power adjustment value. Adjusting the transmission power for the set of downlink messages may reduce self-interference at the UE, the base station, or both.

Abstract: This disclosure provides systems, methods, and devices for wireless communication that support inter-slot bundling and frequency hopping. In a first aspect, a method of wireless communication includes receiving a message indicating inter-slot bundling for uplink channel inter-bandwidth part (BWP) frequency hopping repetitions. The method also includes receiving bundling information and redundancy value (RV) information for an uplink channel transmission and corresponding uplink channel transmission repetitions. The method includes transmitting the uplink channel transmission with inter-slot bundling and frequency hopping and based on the bundling information and the RV information. The method further include transmitting an uplink channel transmission repetition of the uplink channel transmission with inter-slot bundling and frequency hopping and based on the bundling information and the RV information. Other aspects and features are also claimed and described.

Abstract: Methods, systems, and devices for wireless communication are described for user equipment (UE) indication of uplink scheduling information to a base station. The uplink scheduling information may provide information on a periodic traffic pattern, such as for periodic extended reality (XR) data flows. The uplink scheduling information may provide uplink assistance information (UAI) to a base station to assist the base station with providing uplink resources that efficiently serve an XR session. The UAI may indicate one or more of a periodicity of uplink traffic, an offset between uplink traffic and a packet arrival, a data size for uplink traffic for each time period associated with the XR session, a request to enable uplink transmission skipping, or any combinations thereof. A base station may provide one or more dynamic grants, configured grants, or proactive grants to a UE based on the uplink scheduling information.

Abstract: Methods, systems, and devices for wireless communication are described. A connected mode UE may share reference signal configurations with an idle/inactive mode UE via a sidelink transmission. The connected mode UE may transmit a sidelink transmission including one or more reference signal configurations over a sidelink channel to an idle/inactive mode UE. The reference signal configuration may include reference signal resources that correspond to one or more beams that are tracked by the connected mode UE, such as an active downlink beam or beams adjacent to an active downlink beam. The idle/inactive mode UE may use the reference signal configuration to monitor for and receive one or more reference signals from the base station. In some examples, the connected mode UE may determine to transmit the sidelink transmission based on satisfaction of a trigger condition, such as a proximity of the idle/inactive mode UE to the connected mode UE.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may transmit uplink transmissions according to a frequency hopping pattern. The UE may identify that a first set of uplink transmissions are to be transmitted to a base station by a first set of resources (e.g., a first set of slots, a first set of frequency resources) as indicated by the frequency hopping pattern. The UE may further identify, based on the frequency hopping pattern, that a second set of uplink transmissions are to be transmitted to the base station by a second set of resources (e.g., a second set of slots, a second set of frequency resources). The first set of slots and the second set of slots may each include more than one slot. Additionally, the first and second set of resources may be within a same bandwidth part or in different bandwidth parts.

Abstract: Narrowband (NB) Physical Downlink Control Channel (PDCCH) demodulation reference signals (DMRS) bundling coverage enhancements are disclosed. In some aspects, NB PDCCH DMRS bundling resources and timing are allocated in a virtual domain by a transmitting device, such as a base station. In some aspects the allocated resources are control channel elements (CCEs); the CCEs are allocated according to a pattern in the virtual domain. The base station may transmit NB PDCCH transmissions and corresponding DMRS transmissions in physical domain resources that correspond to the virtual domain resources, the CCE allocation pattern. In some aspects, the NB PDCCH DMRS can be used with PDCCH repetitions. To illustrate, a base station may repeat a PDCCH transmission (e.g., payload data thereof) in multiple particular PDCCH candidates of a plurality of PDCCH candidates. The particular PDCCH candidates may be identified based on PDCCH candidate number or a reference slot or search space set occasion.
