    Abstract: A base station (BS) and user equipment (UE) are configured to perform measurement/reporting and spectrum coordination request/response in wireless networks. A method for operating a UE includes receiving configuration information for measuring interference from a neighboring cell, measuring the interference from the neighboring cell based on the configuration information, and computing a change in the measured interference from the neighboring cell based on a current measured interference level and a previous measured interference level. The method further includes determining, based on at least in part a determination that the change in the measured interference exceeds a first threshold, whether to generate a measurement report and transmitting the measurement report on an uplink channel.

    Abstract: A service management and orchestration (SMO) entity enabling a functional split between a non-real-time (RT) radio access network (RAN) intelligent controller (RIC) and an external artificial intelligence (AI)/machine learning (ML) server will, during a data collection phase, utilize the SMO entity and the non-RT RIC to collect and process RAN data and non-RAN data and, during a data transfer phase, transfer processed RAN and non-RAN data from the SMO entity to an external AI/ML server via an interface. During a training model input phase, the SMO entity receives a trained AI/ML model, metadata, and training results from the external AI/ML server via an interface and, during a configuration phase, the SMO entity uses the trained AI/ML model within the SMO entity and the non-RT RIC to transfer configuration parameters to a near-RT RIC.

    Abstract: Directional sensing capability, including number of beams, beam-width, analog or digital beam sweeping, and supported waveforms, may be indicated by a user equipment (UE), which may then receive a configuration for directional sensing including number of beams, maximum or minimum beam-width, reception time between transmission beam sweeping, and waveform. The UE then performs directional sensing based on the received configuration. The configuration for directional sensing may be for one of monostatic sensing with reception periods between consecutive sensing signal transmissions or bistatic sensing using a plurality of beams. The UE's directional sensing capability may include capability of spatial multiplexing of sensing signals with communication signals. The configuration for directional sensing may permit spatial multiplexing of sensing signals with communication signals. The UE may determine to perform spatial multiplexing of sensing signals with communication signals based on orthogonality of a desired sensing beam with a beam for communications.

    Abstract: A time domain resource configuration indicates a time domain resource for sensing operations by a user equipment, and a frequency domain resource configuration indicates a bandwidth part (BWP) for the sensing operations. The user equipment performs the sensing operations using the indicated time domain resource and the indicated bandwidth part. The time domain resource configuration may include a sensing type indicator S for the time domain resource for sensing operations, and may indicate that dynamic triggering of sensing is allowed. The BWP for the sensing operations may comprise BWP(s) selectively activated for the sensing operations, and may indicate BWP(s) that overlap a BWP used for cellular communication. Assistance information for interference between sensing operations and cellular communication may be transmitted by the user equipment, which may subsequently receive a configuration for coexistence of the sensing operations and the cellular communication.

    Abstract: Methods and apparatuses for multiple concurrent random access procedures. A method for operating a user equipment includes receiving first configuration for a random access (RA) procedure, initiating a first RA procedure on a cell based on the first configuration, and initiating a second RA procedure on the cell prior to completion of the first RA procedure. A method for a base station includes transmitting a first random access response (RAR) and a second RAR. The first RAR includes a first temporary cell radio network temporary identifier (TC-RNTI) and a first uplink grant. The second RAR includes a second TC-RNTI and a second uplink grant. The method further includes receiving a first PUSCH scheduled by the first uplink grant and a second PUSCH scheduled by the second uplink grant. The first PUSCH includes the first TC-RNTI. The second PUSCH includes only the first TC-RNTI or both the first and second TC-RNTIs.

    Abstract: Doppler pre-compensation is performed on synchronization signals using each of multiple Doppler pre-compensation patterns to generate a plurality of sets of Doppler pre-compensated synchronization signals that are transmitted using one or more beams. A signal indicating the Doppler pre-compensation patterns used is transmitted in one of a system information block (SIB) or a radio resource control (RRC) reconfiguration message, in connection with initial access by a user equipment (UE), idle UE cell reselection, connected UE data channel reception, or UE handover. The signal indicates Doppler pre-compensation patterns for a transmitting cell and Doppler pre-compensation patterns for one or more neighbor cells. The synchronization signal comprises a synchronization signal block (SSB) including a primary synchronization signal (PSS) and a secondary synchronization signal (SSS). Received Doppler pre-compensated synchronization signals are combined in the time domain in connection with timing synchronization detection, frequency offset (FO) estimation, or reference signal received power (RSRP) measurement.
