Abstract: A first cell transmits a virtual cell identifier and state information associated with the virtual cell identifier over an interface to a second cell. The first cell and one or more third cells use the virtual cell identifier for transmissions to first user equipment. The state information indicates one of a plurality of states that indicate whether the virtual cell identifier is associated with at least one non-virtual reference signal for the first cell, the second cell, or one or more third cells. The second cell receives the virtual cell identifier and the state information and transmits the virtual cell identifier and state information over an air interface to second user equipment served by the second cell. The second user equipment performs interference cancellation or suppression of transmissions to the first user equipment based on the virtual cell identifier and the state information.

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: Method and apparatus for supporting a partial sub-frame data transmission in LTE systems. The transmitting device performs a channel assessment in a previous sub-frame in an unlicensed carrier (S110). After a successful channel assessment, the transmitting device starts a data transmission (S120). The transmitting device transmits a control message for indicating the data transmission in (E)PDCCH (S140). 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.
