Abstract: The present disclosure provides a method for indicating a modulation and coding scheme (MCS), including a step of when it is determined that a UE supports a downlink 256QAM mode, indicating the 256QAM mode using current information indicating the MCS or extended information indicating the MCS in downlink control information (DCI). The present disclosure further provides a method for receiving downlink data, including a step of, after a UE has received information indicating an MCS which includes indication information indicating a 256QAM mode, receiving the downlink data according to the 256QAM mode and a corresponding TBS index. The present disclosure further provides devices for implementing the above methods.

Abstract: The present disclosure discloses a method and a system applied in a Physical Uplink Shared Channel (PUSCH) Hybrid Automatic Repeat Request (HARQ) timing for Carrier Aggregation (CA). when a Round-Trip Time (RTT) of a scheduling cell is not equal to 10 ms, an HARQ of the PUSCH on a scheduled cell may follow a timing mode of a time slot configuration of config#1 defined by the 3rd Generation Partnership Project (3GPP). By using the solution according to the present disclosure, it is ensured that there is at least one sub-frame being able to work properly in the PUSCH on the scheduled cell and the transmission efficiency is maximized except for two circumstances where the time slot configuration of the scheduling cell and the time slot configuration of the scheduled cell are (config#6, config#0) and (config#0, config#6) defined by the 3GPP.

Abstract: A method is provided to associate at least one user equipment to a plurality of component carriers. A carrier-to-interference ratio is calculated for each of component carriers available for the user equipment. Differences between the calculated carrier-to-interference ratios are calculated, with each difference being associated to a different one of the component carriers intervening in the difference, the component carriers being ordered in the decreasing order of their carrier frequency. The user equipment is associated with the component carrier having the lowest difference.

Abstract: A method and apparatus are provided for allocating carriers from a list of carriers in a telecommunication network. Each of the carriers allow transmission of a transmission control frame, each of said transmission control frame has a data block corresponding to a data stream and an indication of the previous carrier allocated to the data stream. The method includes, for a transmission control frame and a carrier selected for allocation to the transmission control frame in the list of carriers, the steps of determining the number of binary bits needed to identify the number of carriers in the list of carriers, coding the indication based on the determined number of binary bits, and removing the allocated carrier from the list of carriers.

Abstract: A method for an 8-antenna downlink control channel, is described. the method includes virtualizing a first pair and a third pair of dual-polarized antennas as a first port, and virtualizing a second pair and a fourth pair of dual-polarized antennas as a second port. The weighted values of the broadcast right of the four antennas in the first port satisfy that the weighted value of one antenna is +1 and the weighted values of the other three antennas are ?1, or the weighted value of one antenna is ?1 and the weighted values of the other three antennas are +1, and weighted values of the broadcast right of the four antennas in the second port satisfy that the weighted value of one antenna is +1 and the weighted values of the other three antennas are ?1.
