Abstract: Embodiments provide a method for configuring a serving cell in dual connectivity, user equipment, and a base station. According to the method, a master eNodeB sends RRC connection reconfiguration signaling to the user equipment, where the RRC connection reconfiguration signaling carries indication information used to indicate whether an SFN of the master eNodeB and an SFN of the secondary eNodeB have same parity, or carries an SFN of the secondary eNodeB. The UE executes primary secondary cell pSCell configuration at the secondary eNodeB according to the RRC connection reconfiguration signaling. The UE may determine parity of the SFN of the secondary eNodeB according to the received indication information or the SFN of the secondary eNodeB, and then the UE performs random access to the SeNB.

Abstract: The present disclosure provides an RRM measurement method and apparatus in a TDD system, so as to resolve a current problem that in a process of an inter-frequency measurement or an inter-RAT measurement in a TDD system, UE cannot perform an RRM measurement on a cell whose TDD uplink-downlink configuration identifier is 0. In embodiments of the present disclosure, UE performs an RRM measurement on a cell whose TDD uplink-downlink configuration identifier is 0 by using a corresponding RRM measurement method according to measurement indication information that is carried in an RRM measurement message delivered by a network device. By means of the technical solutions in the present disclosure, UE can perform an RRM measurement on a cell whose TDD uplink-downlink configuration identifier is 0 by using an RRM measurement method.

Abstract: The present invention provides a signal determining method and an apparatus, so as to resolve a problem, in a conventional positioning method, that a signal receiving device cannot accurately determine whether a received signal is an aggregated reference signal, and consequently, positioning fails due to a relatively large error of location information obtained by means of positioning. The method is as follows: A signal receiving device may estimate, according to a TAE between at least two subcarriers used by a signal sending device to transmit a reference signal and a reference signal sent by the signal sending device on each subcarrier, an aggregated reference signal that is sent by the signal sending device and that is obtained after carrier aggregation. After receiving a signal, the signal receiving device determines whether the signal is an aggregated reference signal sent by the signal sending device.

Abstract: A data demodulation method, apparatus, and system are presented. The method includes obtaining notification information indicating that UE is in a high-speed moving state; performing time-frequency synchronization processing on first downlink data according to the notification information to obtain second downlink data; and performing demodulation processing on the second downlink data to obtain third downlink data, where in the demodulation processing, inter-TTIs filtering for a channel estimation is not performed, or a filtering coefficient as a weight of a current TTI for a channel estimation is greater than a filtering coefficient as a weight of a TTI that is at the time when the UE is in the non-high-speed moving state for a channel estimation. The demodulation method is applicable to a high-speed scenario for improving a downlink data throughput of the UE.
