A method performed by at least one processor in a user equipment (UE), the method including receiving, from a base station over a channel, a plurality of reference signals corresponding to a state of the channel. The method further including measuring a subset of the received plurality of reference signals. The method further including transmitting, to the base station within a first time interval, a channel status report corresponding to the measuring of the subset of the received plurality of reference signals and a prediction of one more reference signals received by the UE after the first time interval.

Method and apparatus for beam management using AI/ML

A method is performed by at least one processor in a network node operating in a wireless communication network. The method includes receiving, from at least one user equipment (UE), a data stream including one or more data packets associated with an uplink transmission between the UE and the network node. The method further includes analyzing the data stream to determine whether the at least one UE transmitted one or more data packets not received by the network node. The method further includes, in response to determining the at least one UE transmitted the one or more data packets not received by the network node, performing a corrective action on the data stream. The method further includes completing the uplink transmission based on the data stream after the corrective action is performed.

Method and apparatus for enhancing quality of experience in case of dropped or delayed packets

A method includes determining a least squares channel estimate (LSE) of a channel, removing a first Orthogonal cover code (OCC) sequence from the LSE thereby generating a first signal, determining an estimated timing offset of the first signal, adjusting a first timing of the LSE based on the estimated timing offset thereby generating a second signal with an adjusted timing, removing a second OCC sequence from the second signal thereby generating a third signal, determining a channel estimate of the channel based on the third signal, determining a noise power of a received signal, determining a signal power of the received signal, determining a signal to noise ratio (SNR) of the received signal based on the noise power and the signal power, adjusting a data rate of the channel based on the SNR, and transmitting an output signal based on an adjusted data rate of the channel.

Method, apparatus, and computer readable medium

Techniques for reducing power consumption in a radio unit are disclosed. The techniques include determining a number of Multiple-Input-Multiple-Output (MIMO) antenna elements of a MIMO antenna panel required to serve one or more User Equipment (UEs), identifying a number of MIMO antenna elements of the MIMO antenna panel not needed to serve the UEs. The techniques include sending, from an Open Radio Network (O-RAN) Distributed Unit (O-DU) to a O-RAN Radio Unit (O-RU), a beamforming weight of zero assigned to the MIMO antenna elements identified as not needed to serve the one or more UEs, the beamforming weight being sent in a digital domain via a Control plane (C-plane). The MIMO antenna elements assigned the beamforming weight of zero may be disabled thereby reducing the power consumption of the O-RU. Artificial Intelligence algorithms may be implemented to dynamically determine areas where the O-RAN should have more coverage or less coverage.

System and method for power saving in an ORAN with intelligent beamforming weights

A method of beamforming includes collecting data related to a connection between a first user equipment and a network. The method further includes determining whether the first user equipment is eligible for digital beamforming. The method further includes determining, in response to a determination that the first user equipment is ineligible for digital beamforming, whether a moving speed of the first user equipment is above a first threshold value. The method further includes using broad beam beamforming for the connection between the first user equipment and the network in response to a determination that the first user equipment is moving faster than the first threshold value.
