Abstract: Methods and apparatus are provided for transmission and reception of common channel information in a mobile communication system using multi-antenna-based beamforming. A number of beams to be used for transmission to a terminal is determined at a base station. The common channel information is generated corresponding to the number of beams. The common channel information is transmitted from the base station to the terminal through one of the beams.

Abstract: Sparsity assisted channel state information (CSI) reporting or two-step CSI reporting is enabled or disabled for a user equipment. The configuration enabling/disabling sparsity assisted truncation for CSI reporting or two-step CSI reporting includes a domain for transformation of CSI for the sparsity assisted CSI reporting, and a time window for correlated channel. When the configuration enables sparsity assisted truncation for CSI reporting, a fixed number of non-zero coefficients and one or more threshold values for delay/angle or doppler for truncation are configured. When sparsity assisted truncation for CSI reporting is enabled, received the CSI reference signals are measured based on the configuration and a CSI report is transmitted indicating a specific range for which truncation occurred. When two-step CSI reporting is enabled, CSI compression corresponding to the at least one configuration and the time window is performed and CSI feedback is transmitted along with a flag.

Abstract: Capability of a user equipment to support machine learning adaptation by a base station of a reference signal pattern is signaled between the base station and the user equipment. Configuration information from the base station indicates one or more of enabling or disabling of machine learning adaptation of the reference signal pattern, a machine learning model used for machine learning adaptation of the reference signal pattern, updated model parameters for the machine learning model, or whether model parameters received from the user equipment will be used for machine learning adaptation of the reference signal pattern. Model training may be performed or model parameters received, and reference signals are received from the base station. Information on a reference signal pattern may be transmitted by the user equipment to the serving base station. Assistance information may be transmitted by the user equipment to the base station, which configures a reference signal pattern.

Abstract: A method and a network entity in a wireless communication system sharing spectrum resources. The method includes identifying a coordination phase to identify at least one neighboring network entity using the shared spectrum resources and perform reservation of the shared spectrum resources and transmitting, during the coordination phase, a coordination request message to the at least one neighboring network entity. The method further includes receiving, during the coordination phase, a coordination response message from the at least one neighboring network entity and determining an amount of the shared spectrum resources to reserve based on the coordination response message. The method further includes transmitting, to at least one terminal in a cell of the network entity, a data transmission using at least some of the determined amount of the reserved resources.

Abstract: Apparatuses and methods for random access procedures with multiple transmission reception points or cells in a wireless communication system. A method for performing random access (RA) procedures by a user equipment includes receiving a first configuration for RA. The method further includes initiating a first RA procedure with a first transmission-reception point (TRP) based on the first configuration and initiating a second RA procedure with a second TRP prior to completion of the first RA procedure. A method for operating a base station includes transmitting a first configuration for RA corresponding to a first TRP and transmitting a second configuration for RA corresponding to a second TRP. The first TRP and the second TRP are associated with a same cell.

Abstract: Methods and apparatuses for maintaining network information. A method for operating a base station (BS) in a wireless communication network includes receiving a neighbor discovery signal block (NDSB) from a neighbor BS in the wireless communication network, generating measurement information based on the NDSB, and generating a path metric for the neighbor BS based on the generated measurement information. The method further includes determining whether the neighbor BS as an interferer neighbor BS based on comparison of the path metric to a threshold and updating network information maintained at the BS based on the determination of whether the neighbor BS is the interferer neighbor BS.

Abstract: Timing adjustments or frequency offsets that at least partially compensate for Doppler shift (e.g., due to distance of a satellite transmitter or relative speed of a terrestrial receiver) of a signal, physical channel, or resource during wireless transmission are configured. The characteristics compensated comprise one of resource element (RE) mapping, channel state information reference signal (CSI-RS) configuration, bandwidth part (BWP) configuration, or control resource set (CORESET) configuration. Information indicating the multiple configurations is transmitted from a base station (BS) to at least one user equipment (UE). The timing adjustments or frequency offsets are specifically configured for one UE, a group of UEs, or the UEs served by a single serving cell. Joint transmission from multiple cells/TRPs/spotbeams may involve partial/full subcarrier alignment.

Abstract: Doppler pre-compensated control and data signal(s) generated using first and second Doppler pre-compensation patterns, respectively, are transmitted. A signal indicating the Doppler pre-compensation patterns is transmitted. The Doppler pre-compensated control signals comprise synchronization signals, system information blocks (SIBs), a radio resource control (RRC) message, or a physical downlink control channel (PDCCH), and the Doppler pre-compensated data signals comprise a physical downlink shared channel (PDSCH). The signal indicating the Doppler pre-compensation patterns comprises one of an RRC message or a PDCCH, and may indicate absolute Doppler values or a difference between Doppler values. The PDCCH may indicate a time offset between the PDCCH PDSCH.

Abstract: A base station (BS) in a wireless communication network for bandwidth allocation requests (BARs) and method of operating the BS. The method includes receiving an uplink (UL) BAR for an amount of UL resources for transmission of UL data to the BS and determining, based at least in part on the UL BAR, an amount of backhaul resources for transmission of backhaul data from the BS to a parent BS of the BS via a wireless backhaul connection. The method further includes receiving the UL data; transmitting, to the parent BS at least before reception of the UL data is complete, a first BAR indicating the determined amount of the backhaul resources; and transmitting the received UL data to the parent BS via the wireless backhaul connection based on the first BAR.
