Abstract: A method for reporting UE capability information includes: obtaining, by user equipment (UE), UE capability information of the UE; when 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 UE capability information, where each piece does not exceed the maximum tolerance that can be processed by the PDCP layer; and reporting at least one piece of the at least two pieces of UE capability information to a network side device. According to this method, the UE capability information is split on a UE side, and reported to the network side device 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.

Abstract: A user equipment obtains configuration information used to detect a received signal strength indicator (RSSI) value of a signal on an unlicensed frequency, samples the signal on the unlicensed frequency at a sampling interval included in the configuration information to obtain RSSI values of the signal on the unlicensed frequency sampled at sampling moments. The user equipment determines statistics on the RSSI values of the signal on the unlicensed frequency within a statistical window, obtains an RSSI value statistical result of the signal on the unlicensed frequency based on the statistics, and reports the RSSI value statistical result to a base station.

Abstract: The present invention provides a demodulation reference signal transmission apparatus, system, and method. The method includes: sending, by a base station, a configuration indication to user equipment UE, where the configuration indication is used to instruct the UE to send an independent DMRS and/or instruct the UE to send a combination of a DMRS and uplink data; and subsequently receiving, by the base station, the independent DMRS sent by the UE; and/or receiving the combination of the DMRS and the uplink data sent by the UE. In this way, the base station can trigger the UE to send the foregoing DMRS to complete frequency offset estimation, thereby improving accuracy of the frequency offset estimation.

Abstract: The present disclosure relates to a terminal device, in which a processing module selects one or more normal carriers or special carriers from a first carrier set for an uplink subframe, where the first carrier set includes all carriers in carrier aggregation that are used by the terminal device to send a first uplink subframe; and a sending module cancels sending of the uplink subframe on one or more carriers, where the special carrier is a carrier on which the terminal device sends neither uplink data nor uplink control information in uplink, and the normal carrier is a carrier that is used by the terminal device to send uplink data and/or uplink control information. An uplink subframe on some carriers is rejected, thereby resolving a problem that information such as a downlink channel characteristic of a carrier cannot be obtained when no uplink reference signal is sent on the carrier.
