In aspects, the UL anchor carrier and/or the one or more candidate UL anchor carriers may be respectively associated with one or more ROs. The UE may perform initial access operations over the UL anchor carrier using the associated one or more ROs.

Abstract: Certain aspects of the present disclosure provide techniques for rate-splitting multiple access (RSMA) for a user equipment (UE) group. An example method includes transmitting, to a group of receiver UEs (Rx UEs), an indication that the Tx UE will transmit to the group of Rx UEs using rate splitting multiple access (RSMA), and transmitting to the group using RSMA, wherein transmitting to the group using RSMA comprises: splitting individual messages intended for individual Rx UEs in the group into common messages and private messages, combining the common messages, transmitting the combined common messages using a first precoder, and transmitting the private messages using separate precoders.

Abstract: During positioning of a user equipment (UE), downlink (DL) positioning reference signals (PRS) transmitted by one or more transmission reception point (TRP) in a wireless communication system may be preempted or punctured by higher priority transmissions, such as ultra-reliable low-latency traffic (URLLC). A PRS preemption indication (PI) may be provided to a UE by a serving TRP identifying one or more TRPs affected by preemption. The PRS PI may further identify the time domain and frequency domain of the preempted DL PRS transmissions. The PRS PI may identify the time domain, e.g., based on a number of PRS symbols between two monitoring occasions, wherein only PRS symbols that contain downlink positioning reference signals associated with the group of TRPs are counted. The PRS PI may identify the frequency domain by identifying at least one of four or more frequency sub-bands of the preempted DL PRS transmissions.

Abstract: Wireless communications systems and methods related to communicating a serving cell dormancy indication field and acknowledgement. In some implementations, a wireless communication device (e.g., user equipment), may detect a physical downlink control channel (PDCCH) with a secondary cell (Scell) dormancy indication field. The user equipment can change states from an initial state to another state (e.g., a dormancy-like state to a non-dormancy like state) based on detecting Scell indicator field in the PDCCH. The user equipment may also transmit a hybrid-ARQ acknowledgment (HARQ-ACK) in response to the detecting the PDCCH with the Scell dormancy indication field. Other aspects and features are also claimed and described.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive, a signal indicating a configuration for the UE to report channel state information (CSI) associated with a first set of reference signals. In some examples, the UE may receive a set of reference signals less than the first set and evaluate one or more rules for generating a CSI report based on receiving the set of reference signals. In some examples, the UE may refrain from generating the CSI report if none of the reference signals from the first set are received. In some examples, the UE may refrain from generating the CSI report of at least one reference signal is missing from the first set. In some examples, the UE may refrain from generating the CSI report if a threshold number of reference signals are missing from the first set.

Abstract: Methods, systems, and devices for wireless communications are described. Wireless communications systems may employ one or more scheduling constraints to support efficient utilization of techniques for intra-device handling of overlapping scheduled uplink transmissions (e.g., intra-device dynamic resource cancelation and multiplexing) as well as inter-device handling of overlapping scheduled uplink transmissions (e.g., inter-device dynamic resource cancelation and multiplexing). Scheduling constraints may define how a device may apply intra-device and inter-device multiplexing and cancelation rules for various scenarios. For example, a device may apply intra-UE cancelation rules before inter-device cancelation rules. In some examples, later-received grants or uplink preemption indications (ULPIs) may not change a device's previously established decision to drop an uplink transmission.

Abstract: A method of wireless communication by a user equipment (UE) includes receiving, from a base station, signaling indicating an assignment of resources in a physical time domain to a set of contiguous symbols in a virtual domain. Each symbol of the set of contiguous symbols may be associated with a respective orthogonal frequency-division multiplexed (OFDM) symbol of a respective one of multiple sets of one or more contiguous OFDM symbols in the physical time domain. Each set of OFDM symbols may be associated with a slot in the physical time domain. The method also includes mapping the physical time domain resources to the multiple sets of OFDM symbols based on the assignment of the physical time domain resources to the set of contiguous symbols. The method further includes receiving or transmitting the multiple sets of OFDM symbols on the physical time domain resources based on the mapping.

Abstract: Methods, systems, and devices for wireless communications are described. A transmitting device may transmit an expiration indication to a receiving device as part of a scheduling message for a transport block. The expiration indication may provide information related to an expiration time for the transport block. If the expiration time is reached prior to successful reception by a receiving device, the receiving device may assume that the transport block has expired and may refrain from transmitting a retransmission grant, or may empty a hybrid automatic repeat request (HARQ) buffer associated with the transport block. If the transmitting device fails to successfully receive an indication from the receiving device of a successful reception of the transport block prior to the expiration period, the transmitting device may also assume that the transport block has expired.

Additionally or alternatively, the UE may identify a carrier aggregation configuration for a set of communication links where at least one communication link of the set is a sidelink. The UE may determine an event associated with the sidelink that triggers a power headroom report, and transmit the power headroom report based on the determined event associated with the sidelink that triggers the power headroom report.

Abstract: Some techniques and apparatuses described herein enable transmission of an uplink control channel in a cross-carrier fashion, where determination of a slot for the transmission is performed based at least in part on a reference component carrier (CC), of a plurality of CCs. For example, the reference CC may be indicated by scheduling information associated with a downlink channel, or may be determined by the UE (e.g., based at least in part on an order associated with the plurality of CCs and availability of a slot for an uplink control channel on the plurality of CCs). In this way, ambiguity with regard to determination of the slot for transmission of the uplink control channel is reduced, thereby providing improved control channel performance, improved resource utilization, and more robust implementation of cross-carrier uplink feedback.

Abstract: A method for wireless communication by a network node includes transmitting, to a group of user equipment (UEs), radio resource control (RRC) signaling to configure a function for enabling and disabling hybrid automatic repeat request (HARQ) feedback for a set of N instances of a multicast transport block (TB). The method also includes transmitting, to the group of UEs, the set of N instances of the multicast TB. The method further includes transmitting, to the group of UEs, a downlink control information (DCI) message on a group-common physical downlink control channel (PDCCH) with a cyclic redundancy check (CRC) scrambled by a group-common radio network temporary identifier (RNTI) configured for the group of UEs. The method also includes receiving, from one or more UEs of the group of UEs, a HARQ feedback message associated with one or more instances of the set of N instances after transmitting all N instances.

Abstract: Methods, systems, and devices for wireless communication are described. A wireless communication device (e.g., a user equipment (UE)) may receive information indicative of sets of resources for performing a cross link interference (CLI) measurement during one or more subband full-duplex (SBFD) symbols or one or more non-SBFD symbols. Additionally, the information may indicate additional sets of resources for reporting results of the CLI measurement. The wireless communication device may perform the CLI measurement using one of the sets of resources based on whether the CLI measurement is performed in one or more SBFD symbols or one or more non-SBFD symbols. In some examples, the wireless communication device may transmit a report indicating the results of the CLI measurement using a respective additional set of resources.
