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 frequency division multiplexing (FDM) parameter associated with a random access procedure. The UE may transmit a Message 1 (Msg1) or a Message A (MsgA) on one or more resources in accordance with the configuration information and based at least in part on the one or more resources having a valid status, wherein at least one of the FDM parameter or the valid status is based at least in part on the random access procedure utilizing a narrowband channel bandwidth. Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may transmit a capability message indicating a threshold quantity of downlink control information (DCI) messages the UE is capable of processing in a time duration for each component carrier (CC) that is associated with multiple control resource set (CORSET) pool index (e.g., CORESETPoolIndex) values. The UE may receive a first control message (e.g., a radio resource control (RRC) configuration message) indicating a configuration that enables the UE to process the threshold quantity of DCI messages. The UE may receive a second control message indicating that a CC is configured with the multiple of CORESETPoolIndex values. The UE may receive one or more DCI messages associated with the CC based on the threshold quantity of DCI messages and the CC being configured with the multiple CORESETPoolIndex values.

Abstract: Wireless communications systems and methods related to communicating ACK/NACK feedbacks for multi-user and unicast physical down-link shared channel (PDSCH) communications are provided. A UE may receive a multi-user PDSCH communication including a first transport block (TB) for the UE and may receive a unicast PDSCH communication including a second TB for the UE. The UE may determine a hybrid automatic repeat request (HARQ) codebook for the first TB associated with the multi-user PDSCH communication and the second TB associated with the unicast PDSCH communication. The UE may transmit a first acknowledgement/negative-acknowledgment (ACK/NACK) feedback for the first TB and a second ACK/NACK feedback for the second TB based on the determined HARQ codebook.

Abstract: Schemes and mechanisms for timing advance adjustment are provided. In a method for wireless communication, a BS transmits, to a user equipment (UE), a first timing offset configuration associated with a first reconfigurable intelligent surface (RIS) state and a second timing offset configuration associated with a second RIS state. The BS transmits, to the UE, a timing offset indication indicating one of the first timing offset configuration or the second timing offset configuration. The BS receives, from the UE based on the timing offset indication, an uplink (UL) communication.

Abstract: Certain aspects of the present disclosure provide techniques for remote interference mitigation between base stations using reference signals. Certain aspects provide a method for wireless communication by a first base station (BS). The method includes receiving a reference signal (RS) from a second BS. The method further includes performing interference measurement corresponding to interference from the second BS based on the RS being associated with the second BS.

Abstract: Aspects are provided which improve RLM by allowing a UE to apply a longer monitoring window for out-of-sync determinations before the UE triggers an RLM timer for in-sync determinations. The UE first obtains a reference signal from a base station. The UE then determines multiple groups of consecutive out-of-sync indications in response to the reference signal. For example, the UE may perform looped out-of-sync monitoring, multi-cell or carrier monitoring, or a combination of such monitoring to determine the multiple groups of out-of-sync indications. Afterwards, the UE triggers the RLM timer in response to determining the multiple groups of consecutive out-of-sync indications. As a result, the UE may perform additional out-of-sync monitoring during RLM before proceeding with in-sync monitoring, thus allowing the UE to account for rapid BLER changes (ping-pong effects) that may occur in HAPS systems due to tropospheric turbulence and enabling more accurate RLM determinations and minimal RLF detections.

Abstract: Certain aspects of the present disclosure provide techniques for slot format configuration. A method that may be performed by a user equipment (UE) includes sending a message to a base station (BS) with UE capability information indicating one or more capabilities of the UE. The method includes receiving signaling from the BS indicating a semi-static slot format configuration based on the UE capability information, the slot format configuration including one or more slot format patterns and a cyclic shift (CS) associated with one or more slot format patterns. The method includes communicating with the BS based on the semi-static slot format configuration and the CS.

Abstract: A user equipment (UE) precodes data for transmission by the wireless device based on a hybrid codebook comprising a first set of one or more discrete Fourier transform (DFT) precoders and a second set of one or more non-DFT precoders. The UE also transmits a signal based on the precoded data.
