Abstract: A computer-implemented method for operating in a reduced power mode (RPM) of a user equipment (UE) in communications with a base station pursusant to a normal power mode (NPM). The NPM is characterized by one or more normal-power parameters comprising a normal sampling frequency and a normal signal bandwidth. The RPM is characterized by one or more reduced-power parameters comprising a reduced sampling frequency or a partial signal bandwidth. The UE determines whether to enter into the RPM for a duration. In response to determining to enter into the RPM for the duration, the UE powers down into the RPM by operating with the one or more reduced-power parameters for the duration of the RPM. Upon expiry of the duration of the RPM by the UE, the UE powers up into the NPM by resuming to the sampling frequency of the NPM and the signal bandwidth of the NPM.

Abstract: A reference signal transmission method and a related device and system are disclosed. The method includes: determining, by a first base station, at least one target subframe on a target frequency band, where the target frequency band is a frequency band whose uplink and downlink transmission directions are configurable, and uplink-downlink timeslot configurations and/or transmission directions of the first base station and a neighboring second base station in the at least one target subframe are different; and sending, by the first base station, a first reference signal to first user equipment UE in the at least one target subframe, where the first UE is UE served by the first base station. When embodiments of the present invention are implemented, a reference signal can be transmitted on a flexible frequency band, thereby effectively reducing interference between reference signals between neighboring cells in a flexible duplex system.
