Procedures, methods, architectures, apparatuses, systems, devices, and computer program products are disclosed that may be implemented in wireless transmit/receive unit (WTRU). In one representative method, the WTRU may determine a processing time value and/or type from among a plurality of processing time values and/or types and the method may include sending, by the WTRU to a network entity, a first message indicating the determined processing time value and/or type and receiving a second message indicating a confirmation of the determined processing time value and/or type. The method further may include applying, after receiving the confirmation of the determined processing time value type, the determined processing time value and/or type to processing of a target associated with the determined processing time value and/or type.

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive downlink control information indicating precoding information associated with a multi-panel uplink transmission, the precoding information including at least one of a demodulation reference signal port configuration associated with the multi-panel uplink transmission, a multiple-input multiple-output precoding configuration associated with the multi-panel uplink transmission, or a quantity of layers associated with the multi-panel uplink transmission. The UE may precode the multi-panel uplink transmission for transmission via a first antenna panel of the UE and a second antenna panel of the UE based at least in part on the precoding information. The UE may transmit, using the first antenna panel and the second antenna panel, the precoded multi-panel uplink transmission. Numerous other aspects are provided.

Methods, systems, and devices for wireless communications are described. A user equipment (UE) may perform an operation to obtain one or more channel state information (CSI) resources (e.g., new resources) from a set of resources indicated by a CSI report configuration. For example, the UE may aggregate or separate respective resources of the set of resources to obtain one or more CSI resources. The operation may be performed based on a first number of antenna ports associated with each resource of the set of resources and a second number of antenna ports associated with a codebook configuration. Thus, performing the operation may result in the UE forming one or more CSI resources for measuring CSI on the one or more CSI resources. The UE may transmit a CSI report based on measuring the CSI for a set of reference signals received on the one or more CSI resources.

A method for operating a user equipment comprises receiving configuration information including information on a beam indication indicating N uplink (UL) transmit beams, where N>1; receiving the beam indication; determining whether an event is detected; selecting a beam from the N UL transmit beams based on whether the event is detected or not; and transmitting an UL transmission using the selected beam, wherein the beam refers to a spatial property used to receive or transmit a source reference signal (RS).

An apparatus comprising: a switching arrangement configured to split an antenna array panel, comprising an array of antenna elements, to provide a first part for a first downlink beam from a first transmitter and a second part for a second downlink beam from a second transmitter, wherein the first downlink beam and the second downlink beam have independent directions; and the switching arrangement being configured to enable inter-band carrier aggregation at receiver circuitry using a first component carrier received at the first part of the antenna array panel via the first downlink beam and a second component carrier received at the second part of the antenna array panel via the second downlink beam.

Disclosed is a method including enabling, for channel state information (CSI) acquisition by a user equipment (UE) in multiple transmission/reception point (TRP) coherent joint transmission (CJT), different beam selections in each panel of a type 1 multiple panel codebook, and applying multiple input multiple output (MIMO) precoding to the multiple panels.

Embodiments of the invention relate to a wearable device comprising a body portion including a front-end system, one or more sensors, and a beam management circuit, and an external portion connected to the body portion comprising a first antenna array. The frontend system is operable to condition radio-frequency signals communicated via the first antenna array to thereby form a beam. The beam management circuit is configured to control the frontend system to manage the beam, such as by switching transmission between different subsets of antenna elements of the antenna array, or by switching transmission from the first antenna array to a second antenna array located on the external portion.

Apparatuses and methods for uplink (UL) transmission are provided. A method for operating a user equipment (UE) includes receiving information about an uplink (UL) transmission based on N antenna ports and receiving a first indicator (I) indicating G groups of antenna ports, g.sub.1, . . . , g.sub.G. Group g.sub.i includes n.sub.i antenna ports selected from the N antenna ports.

A method for operating a user equipment comprises receiving configuration information including information on a beam indication indicating N uplink (UL) transmit beams, where N>1; receiving the beam indication; determining whether an event is detected; selecting a beam from the N UL transmit beams based on whether the event is detected or not; and transmitting an UL transmission using the selected beam, wherein the beam refers to a spatial property used to receive or transmit a source reference signal (RS).

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a first reference signal (RS) from a first antenna panel of a plurality of antenna panels associated with at least one transmit receive point (TRP) of a scalable cell system that includes a set of anchor TRPs associated with a cell and a set of on-demand TRPs associated with the cell, wherein the first RS is associated with a frequency and a transmission configuration indicator (TCI).
