Embodiments of the present disclosure disclose devices, methods and apparatuses for cell activation. In the embodiments, a terminal determines a pathloss-reference signal (PL-RS) as known for a secondary cell (SCell) with an uplink based on at least one measurement result or a measurement report. The measurement report is triggered due to a cell activation command. Then, the terminal device activates, based on the PL-RS determined as known, the SCell within a first time period. In this way, communication performance related to the carrier aggregation operations can be improved.

A potentiometer device and a method for determining a number of closed DIP switches is provided, which belongs to the field of potentiometers. A DIP switch structure is connected in parallel with a potentiometer. The DIP switch structure at least includes a branch circuit formed by connecting one DIP switch and one resistor in series. Compared with a wire-wound potentiometer, a carbon film potentiometer, a straight slide potentiometer, and a rotary potentiometer, a design of a potentiometer controls whether a resistor is connected to a circuit by a DIP switch, can achieve a required voltage division ratio, high debugging speed, and high efficiency only by closing the switch, and there is no problem of slide wear, resistor body wear, or the like. In addition, the DIP switch has certain stability, a closing/opening state of the DIP switch will not be changed easily.

Example embodiments of the present disclosure relate to relaxing measurements for failure detection in a cell. In example embodiments, a device performs measurements on one or more reference signals on one or more measurement occasions and determines one or more reference signal received power, RSRP, levels of a cell based on the measurements on the one or more reference signals. Further, the device determines one or more reference RSRP levels reflecting radio link quality or beam quality, one of the reference RSRP levels being associated with one of the determined one or more RSRP levels of the cell. The device evaluates a relaxation criterion based on the one or more reference RSRP levels and the one or more determined RSRP levels of the cell. Moreover, the device relaxes measurements for failure detection in the cell, if it is evaluated that the relaxation criterion has been fulfilled for a time period.

Embodiments of the present disclosure disclose devices, methods and apparatuses for cell activation triggered layer 3 (L3) reporting. In an aspect, a terminal device receives a cell activation command to activate a plurality of cells in a frequency band. Based on status of the plurality of cells and association information between cells comprising at least the plurality of cells to be activated in the frequency band, the terminal device determines whether L3 reporting is to be triggered. Based on determining that the L3 reporting is to be triggered, the terminal device transmits an L3 report. By considering the cell status e.g. known/unknown, and the association information among the cells on the same band, the terminal device may determine if L3 reporting is to be triggered for cells on different frequency bands, for example, on frequency range 1(FR1) and frequency range 2(FR2), respectively, and hence achieves a faster cell activation.

The method implemented at a first device comprises receiving, from a second device, a first configuration about a first measurement of first downlink reference signals of the second device and a second configuration about a second measurement of second downlink reference signals of a third device; determining, based on an active bandwidth part of the first device and the first and second configurations, first information for the first measurement and second information for the second measurement; determining a first result of the first measurement based on the first information and a second result of the second measurement based on the second information; and transmitting the first result and the second result to the second device. As such, a fair comparison between the first and second results can be made, and thus it is helpful for the second device to make a correct mobility decision.

Example embodiments of the present disclosure relate to measurement relaxation. In an aspect, a terminal device determines a short discontinuous reception (DRX) cycle and a long DRX cycle configured for the terminal device. Based on at least one of the short DRX cycle or the long DRX cycle, the terminal device determines at least one of (i) whether the terminal device is allowed to relax a measurement, or (ii) a relaxed evaluation period for the measurement. In this way, the UE behavior is predictable and thus communication efficiency or effectiveness in a communication system can be improved.

The method further comprises delaying to apply at least one measurement gap of the one or more measurement gaps. In this way, the delay of the bandwidth part switching procedure is controllable and predictable for both the first and the second device, and further the required necessary interaction after the bandwidth part switching is ensured thereby, while the new measurement gap configuration may be activated as soon as possible.
