摘要： A signal processing method and a related device are disclosed. In the signal processing method, user equipment may obtain configuration information used to detect a received signal strength indicator RSSI value of a signal on an unlicensed frequency, where the configuration information includes sampling parameter information and at least one statistical window that correspond to the signal on the unlicensed frequency, and the sampling parameter information includes a sampling interval; the user equipment samples the signal on the unlicensed frequency at the sampling interval, and obtains RSSI values of the signal on the unlicensed frequency at sampling moments; the user equipment determins statistics on RSSI values of the signal on the unlicensed frequency at sampling moments included in the at least one statistical window, and obtains an RSSI value statistical result of the signal on the unlicensed frequency; and the user equipment reports the RSSI value statistical result of the signal on the unlicensed frequency to a base station. This application can improve accuracy of an RSSI value according to which the base station serving the user equipment selects an idle unlicensed frequency.

摘要： A method for reporting user equipment capability information and an apparatus are disclosed. The method includes: obtaining, by UE, UE capability information of the UE; determining whether a size of the UE capability information exceeds a maximum tolerance that can be processed by a PDCP layer of the UE; if the size of the UE capability information exceeds the maximum tolerance that can be processed by the PDCP layer of the UE, splitting the UE capability information into at least two pieces of part UE capability information, where each piece of split part UE capability information does not exceed the maximum tolerance that can be processed by the PDCP layer; and reporting at least one piece of split part UE capability information to a network side. According to this method, the size of the UE capability information is determined and split on a UE side, and the split UE capability information is reported to the network side for a plurality of times, so as to avoid an error caused when the UE capability information exceeds the maximum tolerance that can be processed by the PDCP layer, and ensure normal operating of a UE capability information reporting process.

摘要： Embodiments of the present invention disclose a mobility management method, user equipment, and a base station. The mobility management method may include: receiving, by user equipment UE in a connected mode, a source identifier of the UE from a first base station, where the source identifier is used to uniquely identify the UE in the first base station; entering, by the UE, a low-overhead state after a low-overhead activation condition is satisfied, where in the low-overhead state, the UE stores a connection context of the UE in the connected mode, and camps on a cell according to a cell reselection criterion during movement; and reporting, by the UE when a first preset condition is satisfied, the source identifier to a second base station to which a second cell belongs, where the second cell is a serving cell on which the UE currently camps. According to the present invention, the UE autonomously performs mobility based on cell reselection after the UE enters the low-overhead state, and reports only location change information of the UE, thereby simplifying a handover procedure and reducing communication resources of a network device.
