Abstract: Methods and apparatus are provided for path switching between an evolved Node B (eNB) and a Mobile Management Entity (MME). The eNB transmits a Path Switch Request message informing that a User Equipment (UE) has changed cells, to the MME. The Path Switch Request message includes an eNB UE S1AP ID, a Tracking Area Identifier (TAI), and cell Identifier (ID). The eNB UE S1AP ID uniquely identifies UE association over an S1 interface within the eNB. The eNB receives a Path Switch Request Acknowledge message including an MME UE S1AP ID and the eNB UE S1AP ID, from the MME. The MME UE S1AP ID uniquely identifies UE association over an S1 interface within the MME. The TAI corresponds to a cell in which the UE is located.

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.
