摘要： 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.

摘要： 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.

摘要： 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.

摘要： 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.

摘要： A method for a beam-specific operation between a base station (BS) and a user equipment (UE) is provided. The method comprises obtaining a configuration for at least one of a downlink (DL) reception or an uplink (UL) transmission, wherein the configuration comprises beam identifiers (IDs) and a slot and symbol configuration for respective ones of the one or more beam IDs. The method further includes performing, according to the configuration information, a DL operation or an UL operation.

摘要： 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.

摘要： Devices and methods for inter-network access management in an shared spectrum wireless communication systems. A method for a method for operating a network entity in a wireless communication system of shared spectrum resources includes transmitting, to a set of neighbor network entities in the wireless communication system, a coordination request message indicating an intended transmission power for a data transmission by the network entity; and receiving, from at least one of the set of neighbor network entities, a coordination response message in response to the coordination request message. The method further includes determining resources of the shared spectrum resources to use for the data transmission based on the intended transmission power and the coordination response message; and transmitting, to at least one terminal in a cell of the network entity, the data transmission based on the determined resources.

摘要： Methods and apparatuses for neighbor discovery and wireless inter-connection in a wireless communication system. A method for operating a base station (BS) in the wireless communication network includes generating measurement information regarding neighboring BSs of the BS in the wireless communication network; determining a first parent BS of the neighboring BSs to connect to based on the measurement information; performing an initial access procedure with the first parent BS to connect to the first parent BS; identifying an end-to-end route for the BS for transfer of data between a user equipment (UE) and a gateway via the wireless communication network; and transferring the data between the gateway and the UE based on the identified end-to-end route.

摘要： A method and an apparatus for transmitting and receiving Time Division Duplex (TDD) frame configuration information are disclosed. The base station transmits TDD frame configuration information as system information to a user equipment through a common control channel so as to dynamically change the TDD frame configuration according to uplink and downlink traffic conditions. The base station may deliver the same system information to all user equipments in the cell, removing ambiguity in User Equipment (UE) operations and avoiding interference. In comparison to an existing method of delivering TDD frame configuration information through system information update, the disclosed method enables user equipments to rapidly cope with traffic changes. In addition, user equipments may receive and apply TDD frame configuration information at the same time.

摘要： Methods and apparatuses for handling radio link failure (RLF) in a wireless communication network. A method for operating a base station (BS) includes detecting occurrence of a RLF on a backhaul link with a parent BS of the BS and transmitting to a wireless communication device connected to the BS a first notification of the RLF indicating to hold data to be transmitted from the wireless communication device to the BS. The method further includes determining whether connection to a core network entity in the wireless communication network can be reestablished and transmitting to the wireless communication device a second notification based on the reestablishment determination.
