  • Patent number: 11956738
    Abstract: A UE performs a cell activation process in a wireless network. The UE calculates a first automatic gain control (AGC) setting based on downlink signals from a base station. The downlink signals include a coarse beam reference signal, a fine beam reference signal, and a conversion indication that indicates a power conversion between the coarse beam reference signal and the fine beam reference signal. The UE further calculates a second AGC setting based on the first AGC setting and the conversion indication. The UE performs a cell search using one of the first AGC setting and the second AGC setting, and performs fine time-frequency tracking using the other of the first AGC setting and the second AGC setting.

  • Publication number: 20230262824
    Abstract: A method for expediting Secondary Cell (SCell) activation is proposed. Under the proposed enhanced direct SCell activation procedure, while adding an SCell to be activated state, the network can add transmission configuration indication (TCI) state information for the SCell in a radio resource control (RRC) signaling message, in addition to TCI state information for a list of candidate TCI states. Upon receiving the RRC signaling message, UE adds the SCell accordingly, and then activates the SCell based on the received TCI state information. Because there is no additional time required for receiving and processing the TCI state information via a media access control (MAC) control element (CE), the SCell activation time is reduced.

  • Publication number: 20230124729
    Abstract: A method of determining the maximum timing change (MTC) based on subcarrier spacing (SCS) configuration for UE measurement and reporting of a neighbor cell in 5 GS is proposed. During measurement procedure, UE first checks whether a neighbor cell has been detectable at least for the time period Tidentity, and becomes undetectable for a period ?5 seconds, and then the cell becomes detectable again. UE then determines the MTC of the cell according to the SCS configuration of the cell. If the timing change of the cell is <MTC, UE reports the measurement report less than a first period (T1) after the measurement event is triggered. Otherwise, if the timing change of the cell is >MTC, UE reports the event triggered measurement reporting less than a second period (T2) after the measurement event is triggered.

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.

  • Patent number: 11611921
    Abstract: 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.

  • Patent number: 11533118
    Abstract: Various examples with respect to synchronization signal block (SSB) raster shift in mobile communications are described. A processor of a user equipment (UE) performs an initial cell search to identify a cell among one or more cells of a wireless communication system. The processor then camps on the identified cell. In performing the initial cell search, the processor scans through a plurality of SSB entries for frequency bands below 3 GHz with a SSB raster spacing and a SSB raster offset frequency that support sub-carrier spacing (SCS) spaced channel raster and 100 kHz channel raster for both 15 kHz SCS and 30 kHz SCS. A minimum channel bandwidth at 5 MHz or higher for 15 kHz SCS or at 10 MHz or higher for 30 kHz SCS is supported. The SSB raster spacing is a common multiple of 15 kHz and 100 kHz. The SSB raster offset frequency for 100 kHz channel raster is a multiple of 30 kHz plus/minus 10 kHz.

Spatial relation switch is based on the valid measurement report. The spatial relation switch delay of aperiodic SRS can be performed when UE has sent the corresponding measurement report to the network.
