摘要： In an aspect of the disclosure, a method, a computer-readable medium, and a wireless communication system including a control device and one or more cells are provided. The control device configures triggering conditions for a user equipment (UE) to initiate transmission of specific uplink (UL) reference signals for UL radio resource management (RRM) measurements. The one or more cells detect the specific UL reference signals transmitted by the UE on specific UL RRM resources based on a reference timing when the triggering conditions are met at the UE. The one or more cells measure the specific UL reference signals to obtain measurement results. The control device decides for a carrier change or a cell change based on the measurement results of the one or more cells. The control device indicates to the UE a set of selected cells or carriers for the UE to connect.

摘要： Apparatus and methods for unknown physical uplink control channel (PUCCH) secondary cell (SCell) activation are proposed. The network node may transmit a PUCCH SCell activation command for an unknown target PUCCH SCell to the UE. After receiving the PUCCH SCell activation command for the unknown target PUCCH SCell, the UE may transmit a layer 1 (L1) report or a layer 3 (L3) report for the unknown target PUCCH SCell to the network node before the unknown target PUCCH SCell is activated. The network node may obtain measurement information based on the L1 report or the L3 report before the unknown target PUCCH SCell is activated. Then, the network node may perform corresponding operations based on the L1 report or the L3 report before the unknown target PUCCH SCell is activated.

摘要： Aspects of the disclosure provide an electronic device including processing circuitry and a method for radio resource management (RRM) measurements. The processing circuitry determines, based on a signal received in a serving cell for the electronic device, a location and mobility of the electronic device. The electronic device is in one of a first state and a second state for RRM measurements. A normal level of RRM measurements is implemented for one or more neighboring cells when the electronic device is in the first state, and a relaxed level of RRM measurements is implemented for the one or more neighboring cells when the electronic device is in the second state. The processing circuitry determines whether the electronic device is to be switched from the one of the first state and the second state to another of the first state and the second state based on the mobility and the location.

摘要： Examples pertaining to synchronization and radio resource management in mobile communications are described. A user equipment (UE) receives a periodic low power synchronization signal (LP-SS) from a network node via a low-power wake-up receiver (LP-WUR) of the apparatus. Then, the UE performs a synchronization based on the periodic LP-SS via the LP-WUR of the apparatus in an event that a main radio of the apparatus is in a power saving mode. The synchronization comprises at least a coarse time synchronization and a coarse frequency synchronization.

摘要： Examples pertaining to reference signal (RS) enhancements in mobile communications are described. An apparatus (e.g., a user equipment (UE)) may receive a minimum broadcast RS from a network node (e.g., a base station (BS)). Based on the minimum broadcast RS, the apparatus may perform basic downlink (DL) measurement. The apparatus may also receive or transmit an on-demand RS from or to the network node in a case that a triggering condition is fulfilled. Based on the on-demand RS, the apparatus may perform additional DL or uplink (UL) measurement.

摘要： A UE in a wireless network performs RRM measurements according to power saving schemes. The UE receives Synchronization Signal Blocks (SSBs), which are broadcast periodically from a base station to a cell served by the base station, and receives additional signal blocks transmitted periodically from the base station. The additional signal blocks and the SSBs use different time-and-frequency resources. The UE performs an RRM measurement according to information received within an RRM measurement window including at least one of the additional signal blocks and a corresponding one of the SSBs. Additionally or alternatively, the UE performs RRM measurements on SSBs with a first cycle period equal to a Discontinuous Reception (DRX) cycle period. In response to an indication that a predefined condition for the RRM measurements is satisfied, the UE performs the RRM measurements with a second cycle period which is at least two times of the first cycle period.

摘要： Apparatus and methods are provided for RRM measurement in the NR network. In one novel aspect, the RRM measurement is configured with one measurement gap for SS block and CSI-RS. In one embodiment, an extended MGL (eMGL) is configured such that the SS block and CSI-RS is measurement within one measurement gap. In another embodiment, the shorter MGL (sMGL) that is shorter than the standard MGL is configured. In another novel aspect, the CSI-RS is allocated adjacent to the SS blocks such that one measurement gap is configured for both the SS block and CSI-RS measurement. In another novel aspect, the CSI-RS measurement is conditionally configured. In yet another novel aspect, the UE decodes the time index of the SS block conditionally.

摘要： Aspects of the disclosure provide a method and an apparatus for performing a bandwidth part (BWP) switching process within different switching delays. For example, the apparatus can include receiving circuitry and processing circuitry. The receiving circuitry can receive from a BS a signaling indicating a change to a BWP configuration of the UE. The processing circuitry can perform a BWP configuration switching process based on the change to the BWP configuration to switch an active BWP configuration to a new BWP configuration, and monitor data transmission from the BS with the new BWP configuration either after a first predefined switching delay when the change to the BWP configuration includes at least one of a predefined set of BWP configuration parameters or after a second predefined switching delay when the change to the BWP configuration does not include any one of the predefined set of BWP configuration parameters.

摘要： A method, a computer-readable medium, and an apparatus are provided. The apparatus may be a UE. The UE receives, on a primary cell, an activation command from a base station for activating a secondary cell between the UE and the base station. The UE receives scheduling information of a set of aperiodic TRSs. The UE receives a trigger indicating transmission of the set of aperiodic TRSs. The UE initiates a RF chain of the UE configured for the secondary cell in an interruption period. The UE receives, in response to receiving the trigger and in accordance with the scheduling information, the set of aperiodic TRSs on the secondary cell prior to receiving an initial SSB or an initial periodic TRS after the interruption period. The UE performs time and frequency tracking on the secondary cell based on the set of aperiodic TRSs.

摘要： Methods are proposed for UE to perform radio link monitoring (RLM) and beam failure detection (BFD) measurements in a relaxed measurement state with an extended evaluation period for power saving. Different criteria for UE to enter and exit the relaxed RLM/BFD measurement state are proposed. In relaxed measurement state, UE can perform RLM/BFD measurements with an extended evaluation period by a scaling factor K when the serving cell quality is higher than a threshold and/or when the serving cell quality variation is lower than a threshold within a time period.
