摘要： UE capability for support of machine-learning (ML) based channel environment classification may be reported by a user equipment to a base station, where the channel environment classification classifies a channel environment of a channel between the UE and a base station based on one or more of UE speed or Doppler spread, UE trajectory, frequency selectivity or delay spread, coherence bandwidth, coherence time, radio resource management (RRM) metrics, block error rate, throughput, or UE acceleration. The user equipment may receive configuration for ML based channel environment classification, including at least enabling/disabling of ML based channel environment classification. When ML based channel environment classification is enabled, UE assistance information for ML based channel environment classification, and/or an indication of the channel environment (which may be a pre-defined channel environment associated with a lookup table), may be transmitted by the user equipment to the base station.

摘要： A method for user equipment (UE) service handover from the serving cell to a target cell includes information regarding a handover timer and an associated handover execution condition. For scheduled handover to be performed upon expiration of the handover timer, the associated handover execution condition comprises one or more abort conditions for aborting the scheduled handover. For two-stage triggered handover to be performed upon receipt of a subsequent triggering message, the handover timer is a handover validity timer and the associated handover execution condition comprises receipt of the handover triggering message prior to expiration of the handover validity timer.

摘要： An electronic device, a method, and a BS for managing a BSs in a shared spectrum. The electronic device receives synchronization measurement reports (SMRs) from the BSs and identifies, based on the SMRs, at least one synchronization source BS and at least one slave BS from the BSs. Transmission timing of the at least one slave BS is based on transmission timing of the at least one synchronization source BS. The electronic device assigns the at least one synchronization source BS to a stratum in a synchronization hierarchy. A synchronization source BS assigned to an n=0 stratum provides a reference frame timing for the plurality of BSs and a synchronization source BS assigned to an n>0 stratum derives frame timing from another synchronization source BS assigned to an n−1 stratum. The electronic device configures synchronization signals and transmits synchronization management indications (SMIs) to the plurality of BSs.

摘要： Methods and apparatuses for resource allocation and timing handling in a wireless communication network. A method of operating a base station (BS) in the wireless communication network includes communicating with at least a first parent BS of the BS in the wireless communication network according to a slot pattern of the BS. The slot pattern indicates slots on which the BS can receive and slots on which the BS can transmit. The method further includes receiving discovery information about a neighbor BS in the wireless communication network and determining whether to add the neighbor BS as a second parent BS of the BS based on the discovery information about the neighbor BS. The method further includes determining a resource allocation to the second parent BS based on the slot pattern of the BS and communicating with the second parent BS based on the determined resource allocation.

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： 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.

摘要： A method for a user equipment (UE) is provided. The method includes receiving first information related to reception of reference signals (RSs). The RSs include channel state information RSs (CSI-RS) or synchronization signals. The RSs are associated with a beam failure (BF) detection, a radio link failure (RLF) detection, or a CSI report. The method further includes receiving second information related to hypothetical adaptation of transmission powers of the RSs and the RSs based on the first information. The method further includes determining, based on the second information and the reception of the RSs, reporting quantities indicating hypothetical channel conditions and transmitting a channel with the reporting quantities indicating the hypothetical channel conditions.

摘要： Methods and apparatuses for cell discontinuous transmission (DTX) and discontinuous reception (DRX). A method performed by a user equipment (UE) includes receiving information related to set(s) of parameters associated with cell DTX or cell DRX on a cell and an indication for activation or deactivation of the cell DTX or the cell DRX. The set(s) of parameters include a cycle, a start offset, or an on-duration timer. The cell DTX and the cell DRX share common parameters. The method further comprises determining an active period and a non-active period of the cell DTX or the cell DRX based on the indication for activation or deactivation, determining a start of the cell DTX or DRX on-duration timer based on a system frame number (SFN), and receiving or transmitting channels or signals on the cell based on the determined active and non-active periods of the cell DTX or the cell DRX, respectively.
