Abstract: A random access method and an evolved Node B (eNB) is described. The method includes: receiving, by a target evolved Node B (eNB), a handover request message including information of multiple target component carriers selected by the source eNB; determining, by the target eNB, whether to allow the multiple target component carriers selected by the source eNB; sending, by the target eNB, a handover request acknowledgement message including information about at least two determined target component carriers for the UE. If the multiple target component carriers selected by the source eNB are allowed by the target eNB, the at least two determined target component carriers include the multiple target component carriers selected by the source eNB. Otherwise, the at least two determined target component carriers include one or more newly configured target component carriers configured by the target eNB.

Abstract: A power saving method includes: sending, by a terminal device, first information to a network device, where the first information is used to indicate processing time for the terminal device to process to-be-processed information; and configuring, by the network device, a time domain resource for the to-be-processed information based on the first information, and sending second information to the terminal device, where the second information is used to indicate the time domain resource. After receiving the second information, the terminal device adjusts the foregoing processing time based on the time domain resource indicated by the second information, to relax a clock of each module corresponding to the processing time. Thereby, a terminal device power saving is implemented. In addition, the network device configures the time domain resource based on the processing time of the terminal device that is indicated by the first information.

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.
