Abstract: The present disclosure relates to uplink control information (UCI) multiplexing for multi-slot physical uplink shared channel (PUSCH) with transport block size (TBS) scaling. Specifically, a user equipment (UE) may determine to transmit UCI on a multi-slot PUSCH transmission. The UE may further identify a number of UCI resource elements (REs) in at least one slot of the PUSCH transmission based at least on a scaling rate. The UE may further perform the PUSCH transmission including the UCI REs.

Abstract: Aspects of the present disclosure provide techniques for determining frequency hopping for physical uplink shared channel (PUSCH) repetitions sent using multiple frequency domain resource allocations (FDRAs). According to certain aspects, a user equipment (UE) determines at least first and second part frequency domain resource allocations (FDRAs) for a first physical uplink shared channel (PUSCH) transmission occasion, transmits a transport block (TB) via at least first and second parts of a physical uplink shared channel (PUSCH) on the first and second part FDRAs with first and second precoders during the first PUSCH transmission occasion, determines at least first and second part FDRAs for a second PUSCH transmission occasion based on a frequency hopping scheme, and transmits the same TB via first and second parts of the PUSCH on the determined first and second part FDRAs with first and second precoders during the second PUSCH transmission occasion.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may receive, from a base station, downlink control information that indicates a wakeup signal for a broadcast or multicast (broadcast/multicast) session in a session-specific field of the downlink control information. The user equipment may selectively perform, for the broadcast/multicast session, a wakeup operation for a discontinuous reception cycle based at least in part on the wakeup signal. Numerous other aspects are provided.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a receiver of orbital angular momentum (OAM) multiplexing based communication may receive, from a transmitter of the OAM multiplexing based communication, a plurality of reference signals corresponding to a plurality of aperture pairs, wherein a reference signal of the plurality of reference signals corresponds to an OAM mode of a corresponding aperture pair; transmit, to the transmitter, a feedback message comprising beamforming information based at least in part on the plurality of reference signals; and receive, from the transmitter, a plurality of data streams that are beamformed based at least in part on the beamforming information. Numerous other aspects are provided.

Abstract: Aspects of the disclosure relate to defining a bandwidth part (BWP) within an operating bandwidth, and sub-BWPs within the BWP, where the sub-BWPs can be used for scheduling frequency-hopping transmissions. As one example, a base station may schedule frequency-hopping transmissions using two or more sub-BWPs. The base station may configure a portion of an operating bandwidth to serve as a BWP used for communicating with a UE over the wireless communication network, define two or more sub-BWPs at different frequency locations within the BWP, each sub-BWP including resource blocks provided in the BWP, and provide a scheduling gap when a frequency hop is scheduled between two or more sub-BWPs at the UE, wherein the scheduling gap accommodates radio frequency retuning at the UE.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a configuration for a control resource set (CORESET) that indicates a precoder granularity unit over which a same precoding is used for resources of the CORESET. The precoder granularity unit may be greater than a resource element group bundle of the CORESET and less than contiguous resource blocks of the CORESET. The UE may monitor for one or more physical downlink control channel candidates according to the configuration. Numerous other aspects are provided.

Abstract: In an aspect, a BS is configured as a serving cell of a UE. The BS transmits data to the UE in accordance with a frequency hopping scheme over a first set of T-F resources of a first BWP and a second set of T-F resources of a second BWP. The BS (or another BS) further transmits, to the UE over a third BWP that is different than the second BWP, a PDCCH including a PI field with a PI associated with the transmitted data over the second set of T-F resources of the second BWP. The UE receives the data and the PDCCH. The UE processes the received data over (at least) the second set of T-F resources based on the PI.

Abstract: Methods, systems, and devices for wireless communications are described. The described techniques relate to an early indication, from a base station to a user equipment (UE), that may allow the UE to determine from the first symbol of a synchronization signal block (SSB) if the system information associated with the SSB is intended for the UE. Thus, when the UE receives the indication that the system information is dedicated to the UE, the UE may determine to receive and decode the remaining synchronization signal block, a master information block, a set of control resources, a downlink control channel, and a downlink shared channel to receive the system information. In some cases, the UE may determine that the system information is generic and end decoding during reception of the SSB to conserve computational resources by avoiding unnecessary decoding.

Abstract: Certain aspects of the present disclosure provide techniques for downlink and/or uplink beam management for full-duplex communications. An example method generally includes receiving, from a wireless node, a RS resource configuration indicating interference RS resources associated with interference reference signal transmissions; monitoring interference RSs via the interference RS resources; for each of the interference RS resources, determining a reception beam based at least in part on the monitored more interference RSs corresponding to the interference RS resources; receiving control signaling, from the second wireless node, indicating QCL information, which also indicates to either refrain from using any monitored interference RS resource in determining spatial reception parameters or identify at least one monitored interference RS resource to use in determining the spatial reception parameters; and determining the spatial reception parameters in accordance with the control signaling.

Abstract: Aspects are provided which allow a user equipment (UE) to identify a low-bandwidth (low-BW) CORESET-0 and associated CSS based on reception bandwidth of the UE. The base station may configure different frequency and time-domain resources of the low-BW CORESET in order to optimize resource utilization of the low-BW CORESET-0, and the low-tier UE may identify these resources of CORESET-0 and CSS from the system configuration information received in a master information block (MIB). As a result, low tier UEs may operate in a same cell as legacy UEs without the need for the base station to transmit additional signaling to either legacy UEs or lower tier UEs for the UEs to receive their respective CORESET-0's and identify a physical downlink channel (PDCCH).
