Abstract: Methods, systems, and devices for wireless communications are described. A method for wireless communication may include receiving a single frequency networked composite reference signal (SFNed RS) at a first port of a user equipment (UE) and receiving a reference signal (RS) at a second port of the UE that is different than the first port of the UE. The method may also include performing channel estimation for at least one of the first port or the second port based at least in part on receiving the SFNed RS and the RS. A method for wireless communication may include transmitting a first portion of an SFNed RS from a first port of a first transmit/reception point to a UE and transmitting a downlink control information message to the UE that indicates at least one transmission configuration indicator state identifier that identifies the SFNed RS.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a base station, a grant for a communication with the base station. The UE may determine whether the communication is associated with a hybrid automatic repeat request (HARQ)-based transmission mode or a HARQ-less transmission mode. The UE may communicate with the base station based at least in part on the grant and the determination of whether the communication is associated with the HARQ-based transmission mode or the HARQ-less transmission mode. Numerous other aspects are described.

Abstract: Certain aspects of the present disclosure provide techniques for low complexity physical downlink channel. A method that may be performed by a user equipment (UE) includes determining one or more policies for monitoring one or more physical downlink control channels (PDCCHs) within one or more bandwidth parts (BWPs) for a first type of UE, wherein the one or more policies for the first type of UE are different from a set of policies for a second type of UE; and monitoring for signals from a network entity via the one or more PDCCHs according to the determined policies.

Abstract: A method of wireless communication by a first network device includes predicting spatial inter-cell downlink interference experienced by a UE. The method also includes communicating with a second network device to reduce the spatial inter-cell downlink interference in a direction of the UE by protecting resources across selected resource sets.

Abstract: A configuration for handling downlink traffic jitter in wireless communication systems. The apparatus receives a configuration from a base station comprising a configuration for DRX operation based on a scheduled arrival time of data, wherein the configuration comprises a time offset for a WUS occasion or a DRX on duration for a plurality of DRX cycles of the DRX operation. The apparatus monitors for communication from the base station based on the time offset associated with the WUS occasion or the DRX on duration for each of the plurality of DRX cycles.

Abstract: Apparatus, methods, and computer-readable media for facilitating sidelink resource pool activation and deactivation for sidelink communication are disclosed herein. An example method for wireless communication at a first sidelink device includes identifying a configuration of a bandwidth part (BWP) for sidelink communication. In some examples, the BWP may comprise at least a first resource pool including a first subset of frequency resources and a second resource pool including a second subset of frequency resources. The example method also includes receiving an activation indication activating the second subset of frequency resources of the second resource pool. Additionally, the example method includes activating the second subset of frequency resources of the second resource pool based on the activation indication.

Abstract: In an aspect, a radar controller determines a first transmission configuration for a reference radar signal on a first link from a first base station to a second base station, and a second transmission configuration for at least one target radar signal on at least one second link from the first base station to the second base station, the at least one target radar signal for sensing of at least one target, the first transmission configuration being different than the second transmission configuration. The radar controller transmits the first and second transmission configurations to the first and second base stations. The first base station transmits the reference radar signal and the at least one target radar signal in accordance with the respective transmission configurations.

Abstract: In an aspect, a radar controller determines a radar slot format that configures transmission of a reference radar signal on a first symbol over a first link from a first base station to a second base station followed by at least one target radar signal on at least one second symbol over at least one second link from the first base station to the second base station, and transmits an indication of the radar slot format to the first base station and the second base station. The first base station transmits, and the second base station receives, the reference radar signal and the at least one target radar signal in accordance with the radar slot format.

Abstract: Aspects of the present disclosure relate to wireless communications, and more particularly, to maintain phase coherence for repetitions of uplink channel transmissions across slot boundaries. One example method includes receiving, from a network entity, phase coherence configuration information indicating that the UE is to maintain phase coherence for repetitions of uplink channel transmissions that cross slot boundaries; receiving scheduling information scheduling a plurality of repetitions of an uplink channel transmission; determining, based on the scheduling information, that the scheduled plurality of repetitions of the uplink channel transmission will cross one or more slot boundaries; and transmitting the plurality of repetitions of the uplink channel transmission based on the scheduling information and the phase coherence configuration information.

Abstract: A base station may precode a first reference signal using a first precoder (P1) and at least one second reference signal using at least one second precoder (P2). At least two UEs may measure the first reference signal and the at least one second reference signal, and transmit channel state feedback based on the measuring (m11 and m12 for a first UE, and m21 and m22 for a second UE). The channel state feedback may comprise channel state information compressed by at least one neural network. The base station may derive a higher-level precoder (W) for multiple-input multiple-output (MIMO) downlink transmission to the at least two UEs.
