Abstract: A method is provided for assisting data transmission on a first carrier by indicating a termination point of data transmission in a transmitting device and apparatus thereof, wherein the method comprises the steps of: A. transmitting data on the carrier to a receiving device in a first subframe; and B. transmitting downlink control information to the receiving device; wherein the downlink control information includes a termination point indication for indicating a termination point of the data in the first subframe. The method and apparatus could improve the utilization of subframe and transmission capacity, and enable LTE to satisfy the regulations for unlicensed operation with high spectral efficiency.

Abstract: A transmitting device performs a channel assessment in a previous sub-frame in an unlicensed carrier. After a successful channel assessment, the transmitting device starts a data transmission. The transmitting device transmits a control message for indicating the data transmission in (E)PDCCH. The control message may include the starting time of the data transmission and/or at least one transmission characteristic in the previous sub-frame. The transmission device may transmit an initial control message for indicating a potential data transmission being started in the sub-frame in which the initial control message is transmitting. Method and apparatus enable (E)CCA to take place at any time, and data transmission to start earlier than the next sub-frame boundary after a successful completion of (E)CCA, thus improving the data transmission capacity, especially in circumstances when the maximum length of transmission is constrained.

Abstract: An Active Antenna System (AAS) is used to generate a logical port by performing beam forming operations to process a reference signal applied to its input. The beam forming operations are based on AAS configuration information received by the AAS. The beam forming operations map different operations to different components of the AAS where said operations are performed during the processing of the reference signal resulting in a beam that may be directed at a particular location with a certain amount of power. The AAS configuration information is received by a processor coupled to all of the components of the AAS and said processor converts the received AAS configuration information to control signals causing said components to perform the beam forming operations.

Abstract: The method includes receiving, at a user equipment, a request-to-send (RTS) signal from a base station in an unlicensed channel, the RTS signal including individual IDs or group IDs of multiple user equipments, the multiple user equipments including the user equipment; and identifying whether the RTS signal includes an individual ID or group ID of the user equipment, wherein the identifying includes sending a clear-to-send (CTS) signal to the base station in a licensed channel or the unlicensed channel to allow the base station to perform data transmission to the user equipment in response to the RTS signal including the individual ID or group ID of the user equipment; and ignoring the RTS signal in response to the RTS signal not including the individual ID or group ID of the user equipment.

Abstract: The invention provides the method and apparatus for node and UE to schedule and transmit CTS in a communication network. The method comprises that a node transmits a RTS for indicating a CTS scheduling information to a LTE in an unlicensed band, wherein the scheduling information is used to indicate the LTE to send a CTS in uplink licensed band in response to the RTS. The CTS scheduling information may explicitly include time resource and frequency resource for the UE to transmit the CTS. The CTS scheduling information may implicitly indicate the time and frequency resource for the UE to transmit the CTS. Based on the explicit or implicit schemes of the present application, the scheduling signaling overhead can be reduced and the co-existence problem between LTE-U/LTE-U or between LTE-U/Wi-Fi can be efficiently mitigated.
