Various embodiments herein provide techniques for minimum mean-square error interference rejection combining (MMSE-IRC) processing of a received signal, distributed between a baseband unit (BBU) and a remote radio unit (RRU). The RRU may perform uplink receive beamforming (e.g., using maximum ratio combining (MRC)) based on multiple channel measurements (e.g., a set of multiple sounding reference signal (SRS) channel measurements) obtained on respective measurement signals transmitted by a user equipment (UE). The RRU may send the processed signal to the BBU for further processing. The BBU may perform MMSE-IRC based on the processed signal received from the RRU, e.g., using demodulation reference signals (DM-RSs). Other embodiments may be described and claimed.

Aspects are provided which allow a UE to manage a number of antennas in adaptive receive diversity (ARD) based on packet error rate (PER). The UE measures a downlink PER and determines a number of antennas for receiving a downlink transmission based on the measured, downlink PER. The UE measures downlink PER during switching from a fallback state to a steady state in an ARD state machine, and the UE changes a size of a fallback window in the ARD state machine based on the measured, downlink PER. The UE also disables switching from the steady state to the fallback state based on the measured downlink PER. As a result, a balance between UE reception performance and power savings is maximized and improved downlink data throughput is achieved.

A reflective surface for directing wireless communications signals that includes a plurality of independently reconfigurable elements disposed irregularly on the surface is disclosed. A method of controlling a communication channel of a wireless communication system that includes the reflective surface having an irregular element arrangement is also disclosed.

A WTRU may include a memory and a processor. The processor may be configured to receive beam grouping information from a gNB or transmission and reception point (TRP). The beam grouping information may indicate a group of beams that the WTRU may report using group-based reporting. The group-based reporting may be a reduced level of reporting compared to a beam-based reporting. The group-based report may include measurement information for a representative beam. The representative beam may be one of the beams in the group or represents an average of the beams in the group. Alternatively, the representative beam may be a beam that has a maximum measurement value compared to other beams in the group. The group-based report may include a reference signal received power (RSRP) for the representative beam and a differential RSRP for each additional beam in the beam group.

A system having a platform upon which several phased antenna arrays are mounted and which can communicate with satellites. The system includes a switch that can connect any of the phased array antennas to any of available modems. The system further includes a router that can connect any of the modems to any available computing devices. Based on parameters such as data rates, signal strength, and account information, one or more communication paths are selected for a computing device requesting to communicate with a satellite. Each communication path is established by operating the switch to connect a selected antenna to a selected modem, and operating the router to transfer data between the computing device and the selected modem.

Various aspects of the present disclosure relate to artificial intelligence (AI) enabled beam management. A base station may notify a user equipment (UE) of an availability of AI-enabled beam management and provide configuration parameters for an AI algorithm. The UE may utilize the configuration parameters to configure an AI algorithm. The UE may process a first set of beams utilizing the configured AI algorithm to identify a second set of beams. The UE may notify the base station (and/or other network entity) of the second set of beams, and one or more beams of the second set of beams can be utilized for wireless communication between the UE and the base station and/or other network entity or UE.

An electronic device is provided. The electronic device includes a plurality of antenna modules, and a communication processor. The communication processor may be configured to identify information set for reception of different signals transmitted from a plurality of transmission and reception points (TRPs), identify information related to a strength of a reference signal corresponding to a first TRP among the plurality of TRPs and information related to a strength of a reference signal corresponding to a second TRP among the plurality of TRPs, for a plurality of reception beams set in the plurality of antenna modules, respectively, identify that a first reception beam of a first antenna module among the plurality of antenna modules is selected to receive a signal transmitted from the first TRP and a second reception beam of the first antenna module is selected to receive a signal transmitted from the second TRP, and receive a signal corresponding to the first TRP and a signal corresponding to the second TRP based on a third reception beam of the first antenna module.

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may measure one or more downlink reference signals using one or more candidate beams in a set of candidate beams to obtain reference signal received power (RSRP) measurements for the one or more candidate beams. The UE may estimate, for each of the one or more candidate beams in the set of candidate beams, a downlink spectral efficiency and an uplink spectral efficiency based at least in part on the RSRP measurements associated with the respective candidate beam. The UE may select a downlink receive beam and an uplink transmit beam based at least in part on the downlink spectral efficiency and the uplink spectral efficiency. Numerous other aspects are described.

This disclosure provides systems, devices, apparatus, and methods, including computer programs encoded on storage media, for beam selection and codebook learning techniques based on XR perception information. A UE may receive sensor information indicative of a direction of a current serving beam relative to the UE. The UE may be configured to communicate with a base station based on a BPL associated with the direction of the current serving beam. The UE may perform a measurement for the base station and the UE to communicate over the BPL based on the sensor information indicating that the direction of the current serving beam relative to the UE is different from a previous serving beam direction relative to the UE.

The methods and systems for amplify-and-forward (in-band) relaying relate to beamforming techniques including receive and transmit beamforming for reducing self-interference, and improving Signal-to-Noise Ratio (SNR), or Signal to Interference plus Noise Ratio (SINR), of an incoming signal (to be relayed). The incoming signal is amplified and retransmitted simultaneously with the incoming signal, and over the same frequency band as that of an incoming signal.
