Methods, systems, and devices for wireless communications are described in which a user equipment (UE) may determine wide beam parameters for beamformed communications with a base station based on an identified narrow beam. A UE may receive a reference signal from a base station and identify a narrow beam based on measurements of the received reference signal. Based on the identified narrow beam, the UE may determine a set of wide beam parameters for a wide beam that is to be used for communications between the UE and the base station. The wide beam may have a beam direction that corresponds to a direction of the identified narrow beam, and may have a beam width that is determined as a multiple of a beam width of the identified narrow beam (e.g., x times the beam width of the narrow beam).

Aspects of the disclosure relate to wireless communication including mode division multiplexing of data and reference signals using different orbital angular momentum (OAM) modes. An OAM transmitter may transmit a reference signal (RS) configuration information to an OAM receiver that indicates radio resources for a plurality of OAM modes. The OAM transmitter may further transmit data on a first OAM mode of the plurality of OAM modes using first radio resources of the radio resources indicated by the RS configuration information. The OAM transmitter may further transmit a reference signal on a second OAM mode of the plurality of OAM modes using the first radio resources of the radio resources indicated by the RS configuration information. The OAM receiver may receive the data on the first OAM mode and the reference signal on the second OAM mode. Other aspects, embodiments, and features are also claimed and described.

Methods, systems, and devices for wireless communications are described. In some systems, a device may select antenna elements from a planar array to transmit or receive an orbital angular momentum (OAM) beam. The device may determine a first area (e.g., a first ring area) based on an angular direction over which the device can communicate an OAM beam with a second device and may determine a second area (e.g., a second ring area) on the planar array based on projecting the first area on the planar array. The device may select a set of antenna elements from the planar array that are located within the second area. The device may determine a complex-valued weight for each antenna element of the selected set of antenna elements and may transmit or receive an OAM beam to or from the second device via the set of antenna elements according to the angular direction.

A user equipment (UE) may adjust resources (e.g., time resources, frequency resources) used to transmit repetitions of uplink control information (UCI) over a physical uplink control channel (PUCCH). The UE may adjust two parameters corresponding to different scales (e.g., levels) of adjustment, where a first parameter corresponds to a number of repetitions of a PUCCH resource and a second parameter corresponds to a number of slots within each PUCCH repetition. The UE may adjust the resources based on the first parameter, the second parameter, a size of UCI, a maximum coding rate, or some combination thereof, such that the PUCCH resources carrying UCI satisfy the maximum code rate and UCI size.

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.

The UE may receive, from the base station and based at least in part on the second message, the WUS for the multicast session using a beam from the set of beams. Numerous other aspects are provided.

Beam feedback for passive sensing

Aspects of the disclosure relate to a wireless user equipment (UE) configured to receive a downlink in a network configured for full duplex communication. The UE receives from the network an indication of a maximum rank of an uplink from an interfering, aggressor UE. The UE measures interference of a signal from the aggressor UE, and based on the measurement, determines one or more rank values for the aggressor UE, less than or equal to the maximum rank. The UE may further determine one or more channel parameters for downlink transmissions the UE receives, corresponding to the determined rank values. The UE then transmits a channel state information (CSI) report that includes an indication of at least one of the one or more rank values for the aggressor UE. The CSI report may further include the determined channel parameters. Other aspects, embodiments, and features are also claimed and described.
