Aspects of the subject disclosure may include, for example, obtaining channel cross correlation data relating to multiple user equipment (UEs) being served in a cell, wherein the channel cross correlation data comprises a correlation coefficient associated with a first UE of the multiple UEs and a second UE of the multiple UEs, identifying that the first UE is experiencing decreasing throughput, responsive to the identifying that the first UE is experiencing decreasing throughput, determining whether the correlation coefficient associated with the first UE and the second UE satisfies a correlation threshold, and, based on a first determination that the correlation coefficient does not satisfy the correlation threshold, adjusting a downlink (DL) transmit power allocation for transmissions directed to the first UE. Other embodiments are disclosed.

An electronic device and methods for performing beam management (BM) in systems with antenna arrays capable of operating in combined radar and communication modes are disclosed herein. The electronic device comprises a processor and a plurality of antenna elements configured to operate in a first mode, in which the antenna elements are used for communications with beamforming, and a second mode, in which at least two of the antenna elements are used for radar and the remainder are used for the communications. The processor is configured to perform a mode switch on the antenna elements to switch between the first mode and the second mode, determine, after the mode switch, a new beam to use during a first BM cycle, perform, using the new beam, the first BM cycle to obtain signal quality measurements, and perform a second BM cycle using an updated beam based on the signal quality measurements.

Methods, systems, and devices for wireless communication are described. In multi-user (MU) multiple-input multiple-output (MIMO) wireless communications systems, a base station may perform signaling to indicate information related to ports assigned to one or more UEs. The base station may also signal information regarding ports shared with other UEs, which the UE may use when performing channel estimation. In some examples, the base station may signal a number of ports used per sub-band to the UE or a number of demodulation reference signal (DMRS) ports used by the UE. The base station may signal a sub-set of a total number of ports that are shared by other UEs overlapping with the resource allocation of the UE. The signaling may indicate a number of combs used by the base station in the resource allocation for the UE.

A terminal for communicating with a base station apparatus is disclosed, the terminal including a controller that sets maximum transmission power based on an Effective Isotropic Radiated Power (EIRP) of the terminal; and a transmitter that transmits an uplink signal based on the maximum transmission power. In other aspects, a communication method by a terminal for communicating with a base station apparatus is also disclosed.

Aspects of the subject disclosure may include, for example, a base station that includes a phased array antenna system and a MIMO antenna system. The MIMO antenna system may receive sounding signals sent by user equipment (UE) and determine angular location information for each UE. The angular location information may be used by the phased array antenna system to create antenna beams. The angular location information may also be used to schedule communications with multiple UEs in common beams. Other embodiments are disclosed.

A method, a device, and a non-transitory storage medium are described in which beam configuration management service is provided. A network device of a wireless access network provides the service that includes identifying redundant configurations across carriers associated with a cell group, and links the common beam configurations to these carriers. The service also includes identifying any difference in beam configurations relative to the common beam configurations for a carrier. The service may transmit this beam configuration information in a control plane message to an end device. The end device may use the beam configuration information.

Certain aspects of the present disclosure provide techniques for rate matching of synchronization signal block (SSB) transmissions in non-terrestrial networks (NTNs). A method that may be performed by a user equipment (UE) includes receiving configuration information indicating a beam-specific rate matching pattern for at least one beam of a plurality of beams configured for the UE, wherein a SSB transmission corresponding to each of the plurality of beams is configured using the same set of frequencies, receiving a data channel using the at least one beam, and processing the data channel based on the rate matching pattern.

A base station retransmits data to a user equipment (UE) using a fast beam selection process before the retransmission. The UE transmits an uplink feedback in a beam sweep manner to facilitate fast beam selection in retransmission. The base station can measure the beam sweep patterns from the UE to decide the best beam for retransmission. The UE can send a negative acknowledgment (NACK) or a reference signal in a beam sweep manner to facilitate beam selection at the base station for retransmission.

An electromagnetic unit regulation method and apparatus, and a device and a storage medium are provided. The electromagnetic unit regulation method includes: determining a to-be-regulated electromagnetic unit set S2, where the to-be-regulated electromagnetic unit set S2 is a subset of a regulatable electromagnetic unit set S1; grouping an electromagnetic unit set into X electromagnetic unit groups, where X≥1, and the electromagnetic unit set includes at least one of the to-be-regulated electromagnetic unit set S2 and the regulatable electromagnetic unit set S1; determining an electromagnetic property set to be regulated; and according to the X electromagnetic unit groups, performing regulation on an electromagnetic property of the to-be-regulated electromagnetic unit set S2, where the electromagnetic property is at least one electromagnetic property in the electromagnetic property set.
