Abstract: A method and apparatus are provided for transmitting an uplink Sounding Reference Signal (SRS) by a User Equipment (UE). The method includes receiving information related to an SRS period and an offset for an SRS transmission; generating the uplink SRS; and when the information indicates the SRS period is 2 ms, transmitting the SRS in two Single Carrier Frequency Division Multiple Access (SCFDMA) symbols in a half frame according to the offset for the SRS transmission. When the information indicates the SRS period is 2 ms and a length of an Uplink Pilot Time Slot (UpPTS) in the half frame is two symbols, a first symbol in the UpPTS is indicated by offset 0 and a second symbol in the UpPTS is indicated by offset 1.

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 a method for feeding back data receiving status, applied to a system, are provided. The method includes sequencing, by a User Equipment (UE), downlink subframes for transmitting data with respect to each Component Carrier (CC), generating receiving status feedback information for the first X downlink subframes with respect to each CC according to the result of the sequencing, where X≤M, wherein M is the number of downlink subframes on each CC, and transmitting the receiving status feedback information generated with respect to each CC to a base station. Accordingly, the UE will not misinterpret the receiving status for the downlink subframes due to inconsistencies with the base station between transmitting and receiving feedback. This affects the Hybrid Automatic Repeat Request (HARQ) transmission, saves the uplink overheads occupied by the receiving status feedback information, and increases the uplink coverage area.
