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.

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.

Abstract: 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.

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.

Abstract: A User Equipment (UE) including a wireless transceiver and a controller is provided. The wireless transceiver performs wireless transmission and reception to and from a service network. The controller receives a measurement configuration and a Discontinuous Reception (DRX) configuration from the service network via the wireless transceiver, extends a measurement period indicated by the measurement configuration, and performs a cell measurement via the wireless transceiver in the extended measurement period.

Abstract: 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.

Abstract: In a cooperative spectrum sensing method and system for locationing primary transmitters, each of secondary users transmits to a corresponding one of cognitive radio (CR) base station location information thereof and a received signal strength indicator (RSSI) value generated thereby in response to sensing power signals from the primary transmitters. The CR base stations transmit the location information and the RDDI values of the secondary users to a data fusion center such that the data fusion center obtains the number and locations of the primary transmitters based on the location information and the RSSI values received thereby using a learning algorithm to thereby reconstruct a power propagation map of the primary transmitters.
