Method, device, and system for uplink signaling transmission
In wireless communication, a configuration of uplink (“UL”) signaling transmissions can be through a specific window or pattern. The UL transmission can be concentrated in a time period to save power. Specifically, an active time is determined as a time period for UL signals. Non-active time may include different types of UL signals. The active time may be configured and enabled under different conditions.

receiving a configuration message for active time configuration from a base station, wherein the active time configuration comprises an uplink (“UL”) active time configuration, the UL active time configuration comprises at least one of a duration, an offset, a cycle value, a cycle number, a pattern, a timer, a start parameter, or an end parameter, and an UL active time is determined by at least a cycle which comprises M sub cycles, each of the sub cycles has one duration and a cycle value; and
transmitting UL signaling during an active time.
2 . The method of claim 1 , further comprising:
transmitting a second type of UL signaling during a time other than the active time, wherein the UL signaling other than the second type is transmitted only during the active time.
