Systems and methods for beamforming include a device including at least one of a head wearable display (HWD) or a console. The device establishes a first connection between an active HWD radio-frequency integrated circuit (RFIC) and an active console RFIC. The device compares a modulation and coding scheme (MCS) of the first connection to an MCS threshold. The device performs MCS measurements for a second connection of at least one of an idle HWD RFIC or an idle console RFIC, while the first connection is maintained, in response to the MCS not satisfying the MCS threshold. The device compares the MCS measurements of the second connection to the MCS threshold. The device switches to the second connection when at least one of the one or more MCS measurements satisfies the MCS threshold and/or above the MCS of the first connection.

A user equipment (UE) is provided to select an uplink transmission beam to communicate with a base station in a secondary cell of a carrier aggregation (CA) scheme. The UE can communicate with a first base station in a primary cell (PCell), and receive a command from the wireless network to activate a physical uplink control channel (PUCCH) transmission to a second base station in a secondary cell (SCell). The second base station can be in a being-activated state. The UE can determine whether an uplink spatial relation configuration is provided to the UE, and determine whether the UE supports beam correspondence. Based on the determinations, the UE can select an uplink transmission beam for the PUCCH transmission to the second base station.

There are provided mechanisms for configuring resolution of uplink data. An exemplary radio equipment controller (REC) of an access node includes an interface (RCE-RE interface) to a radio equipment (RE) and processing circuitry. The processing circuitry is configured to cause the REC to provide instructions to the RE regarding a resolution in time and/or frequency domain with which beam direction reports are to be transmitted to the REC on the REC-RE interface. The beam direction reports are based on uplink appointed reference symbols for sounding received by the RE on a radio interface and is to be transmitted from the RE to the REC. The REC may thus configure the resolution of the beam direction reports that are received by the REC.

Techniques for beam width control, and devices and components including apparatus, systems, and methods for beam width control are described herein.

A communication method includes that a sharing AP selects a first beam width used to schedule a sharing STA during coordinated transmission, and the sharing AP sends a coordinated transmission notification to a shared AP, where the coordinated transmission notification includes a coordinated transmission parameter, where the coordinated transmission parameter is obtained based on the sharing STA and the first beam width, where the coordinated transmission notification indicates the shared AP to select, based on the coordinated transmission parameter, a shared STA and a second beam width that are used for coordinated transmission, where the second beam width is one of adjustable beam widths of the shared AP, and where the first beam width is one of at least two adjustable beam widths of the sharing AP.

Techniques and apparatuses are described for integrated access backhaul with an adaptive phase-changing device (APD) are described. In aspects, a donor base station determines to include an APD in a communication path for the wireless backhaul link with a node base station and apportions APD access to the APD for the node base station. The donor base station then communicates with the node base station using the surface of the APD and based on the apportioned APD-access by using the surface to exchange wireless signals with the donor base station.

The present disclosure relates to a method of a radio base station (20) of controlling allocation of resources to wireless communication devices (23, 24), and a radio base station (20) performing the method. In an aspect, a method of a radio base station (20) of controlling allocation of resources to wireless communication devices (23, 24) is provided. The method comprises providing (S101) a first location with radio coverage using at least a first frequency band and a second frequency band and a second location with radio coverage using the first frequency band, the second frequency band being located at a higher frequency than the first frequency band and temporarily reallocating (S102) resources of the second frequency band from the first location to the second location upon acquiring an indication that a wireless communication device (24) at the second location requires improved coverage.
