Abstract: This application provides a signal processing method and apparatus. A network device obtains capability information of a terminal device, where the capability information includes a processing time period for uplink data of the terminal device and a processing time period for uplink control information of the terminal device; determines a first time-frequency resource based on the capability information, where the first time-frequency resource is used to carry first uplink data and/or first uplink control information; and sends first signaling to the terminal device, where the first signaling indicates the first time-frequency resource. This application can improve efficiency of configuring a time-frequency resource by the network device for the first uplink data and/or the first uplink control information of the terminal device, thereby reducing a signal transmission delay.

Abstract: Embodiments of the present invention provide a wireless communications method, apparatus, and system. A terminal is provided. The terminal sets up a connection to a first base station, and stays in always connected mode. Therefore, when the terminal moves in a dense network, handovers of the first base station can be reduced. Further, when the terminal moves in the dense network, frequent signaling interaction is reduced, paging load in the entire network is reduced, and an end-to-end delay in service setup and transmission is reduced.

Abstract: Embodiments of the present invention provide a method, a device, and a system for determining timing advance grouping, and relate to the field of communications, the method, device and system for determining timing advance grouping. The method includes adding, by a base station (eNodeB), a component carrier (CC) for a user equipment (UE); according to obtained timing advance (TA) group information or a preset rule, determining a TA group that the added CC belongs to, where the TA group is a set of CCs that can share a TA; and sending identification information that identifies the TA group to the UE. Embodiments of the present invention are used to determine TA grouping when the eNodeB adds the CC for the UE.

Abstract: Embodiments of the present invention disclose a method and an apparatus for determining an active time of UE, where the method includes: acquiring extension information of a DTX active time of a base station; and adjusting a DTX active time of the UE according to the extension information, and using an overlapped time between the DTX active time of the UE and a DRX active time of the UE as an active time of the UE for listening on a PDCCH channel. The UE can learn a latest DTX condition according to a change of the DTX on a base station side in a manner of acquiring extension information of a DTX active time of the base station, and therefore can determine a correct active time of the UE with reference to DRX of the UE, thereby ultimately ensuring QoS of the UE.
