Abstract: The present disclosure relates to dual connectivity methods. In one example method, a first access network device sends a request message to a second access network device, where the request message is used to request the second access network device to serve as a secondary access network device of a terminal served by the first access network device. Then, the first access network device receives an acknowledgment message from the second access network device, where the acknowledgment message is used to acknowledge to the first access network device that the second access network device agrees to serve as the secondary access network device of the terminal.

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.

Abstract: When a terminal switches from a downlink subframe to an adjacent uplink subframe, generating a first guard period, where that the terminal does not process any signal in the first guard period is defined, that is, the terminal neither receives downlink data nor sends an uplink signal in the first guard period, and therefore uncertainty of a terminal behavior during a downlink-to-uplink switching process of the terminal is avoided, and successful sending of the uplink subframe can be ensured; and when the terminal switches from an uplink subframe to a downlink subframe, generating a second guard period, where the second guard period overlaps the uplink subframe or the downlink subframe, and that the terminal does not process any signal in the second guard period is defined, and therefore uncertainty of a terminal behavior during an uplink-to-downlink switching process of the terminal is avoided.
