Abstract: The present disclosure discloses a method for supporting release of a SIPTO bearer or a LIPA bearer in dual-connectivity architecture. The method is implemented as follows. A MeNB sends a message to a SeNB. The message contains indication information for SIPTO at local network bearer deactivation or LIPA bearer deactivation. The indication information may indicate the SeNB to notify a collocated LGW of releasing PDN connection of SIPTO at local network or the PDN connection of LIPA. After receiving the message, the SeNB removes radio and control plane related resources associated to the UE context or the SIPTO at local network bearer or the LIPA bearer, and if the message contains the indication information for SIPTO@LN bearer deactivation or LIPA bearer deactivation, sends an internal signaling to the collocated LGW to indicate the collocated LGW to release the PDN connection of the SIPTO at local network or the PDN connection of the LIPA. The SeNB is a SeNB supporting functions of the LGW that supports operations of the SIPTO at local network or the operations of the LIPA. By the method of the present disclosure, the SIPTO bearer or the LIPA bearer in the dual-connectivity architecture can be released, thereby avoiding inaccurate operations in an access network, ensuring that the SIPTO bearer or the LIPA bearer can be released duly and accurately, and avoiding inaccurate release of the SIPTO bearer or the LIPA bearer.

Abstract: An apparatus and method for feeding back hybrid automatic repeat request-acknowledgement (HARQ-ACK) information are provided. The apparatus and method include user equipment (UE) that first receives a downlink grant (DL-GRANT) which schedules downlink HARQ transmission in a time-frequency bundling window corresponding to an uplink subframe used for feeding back HARQ-ACK, obtains a DL downlink assignment index (DL DAI) in the DL-GRANT, and determines a mapping value of each DL DAI. Then, according to the mapping value of the corresponding DL DAI, the HARQ-ACK bit of each HARQ feedback unit is mapped to a corresponding bit of a feedback bit sequence. According to the method and apparatus provided by the present disclosure, useless HARQ-ACK bits may be effectively removed, and efficiency for feeding back HARQ-ACK may be increased. As such, a downlink peak rate of a UE is ensured.

Abstract: The present disclosure discloses methods, systems and devices for supporting local breakout in a small cell architecture. A MME sends information of a local breakout bearer for a UE to a MeNB, and the MeNB determines a local home network to which the local breakout bearer belongs according to the received information. When the MeNB is to switch the local breakout bearer between different eNBs, the MeNB selects an eNB in the local home network to which the local breakout bearer belongs as a target eNB. By the present disclosure, the continuity of local breakout traffic may be ensured when a User Equipment (UE) moves in a small cell scenario, thereby avoiding data loss and improving user experiences. Further, a local breakout bearer may be released timely and reasonably, thereby saving system resources.
