    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.

    Abstract: The present invention discloses methods for supporting coexistence of a mobile relay and a fixed relay in a wireless communication network, and corresponding apparatuses. A method comprises: receiving, by a base station, a first message from a relay; determining, by the base station, whether the relay is a mobile relay or a fixed relay based on the first message received from the relay; sending, by the base station, a second message to a mobility management entity, the second message comprising information indicating whether the relay is a mobile relay or a fixed relay so that the mobility management entity can select a corresponding service gateway SGW and a corresponding packet data network gateway PGW for the relay. According to the present invention, coexistence of a mobile relay and a fixed relay in a wireless communication network can be realized with a minimal impact on standardization work.

    Abstract: Embodiments of the present disclosure relates to a communication device working on unlicensed frequency band and a method for executing the same. The method comprises: determining a mapping relationship between multiple quality of service (QoS) priority classes and multiple Listen-Before-Talk (LBT) priority classes, wherein the multiple QoS priority classes are in one-to-one correspondence with multiple QoS requirements; and transmitting radio traffic based on the mapping relationship. Embodiments of the present disclosure proposes the mapping relationship between LBT priority class and various QoS priority classes associated with different radio traffic types and presents signaling design and exchange related to the mapping relationship.

    Abstract: The present disclosure provides methods and apparatuses for HARQ retransmission on an unlicensed carrier in an LTE-LAA system. A method in the base station includes: performing a CCA detection on the unlicensed carrier to determine energy on the unlicensed carrier and, at the same time, initiating an HARQ discarding timer for the unlicensed carrier, when the base station and a UE operate on the unlicensed carrier; comparing the determined energy with a predetermined CCA threshold; if the determined energy on the unlicensed carrier is not smaller than the CCA threshold until the HARQ discarding timer is expired, giving up the HARQ retransmission on the unlicensed carrier; and if the energy is detected to be smaller than the CCA threshold before the HARQ discarding timer is expired, continuing the HARQ retransmission on the unlicensed carrier.

    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.
