  • 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: 20240040418
    Abstract: 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.

  • Publication number: 20240040419
    Abstract: 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.

  • 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: 20230096588
    Abstract: 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.

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.

  • Publication number: 20220104044
    Abstract: 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.

  • Patent number: 11197338
    Abstract: 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.

  • Patent number: 11153840
    Abstract: A user equipment terminal (UE) operates in a wireless network. The UE receives, from a base station, timing advance parameter values which indicate a time difference measured by the base station between uplink and downlink for a band occupied by one or more serving cells. The UE calculates a length of a post-measurement gap (post-MG) time period for the one or more serving cells based on the timing advance parameter values. The post-MG time period is after a measurement gap before uplink transmission. The UE then sends an indication of the length of the post-MG time period to the base station.
