Abstract: The embodiments of the present invention relate to the technical field of wireless communications, and particularly, to a time-division duplexing communication method, system and device, which are used for solving the problem in the prior art that there is no uplink or downlink HARQ sequential relationship for a dynamic uplink and downlink subframe distribution solution. A time-division duplexing uplink data sending method in the embodiments of the present invention comprises: through a subframe n in a wireless frame, user equipment receiving indication information which comes from the network side; and according to the indication information, when it is determined that PUSCH data is required to be sent to the network side, sending the PUSCH data through at least one uplink subframe after the subframe n, the subframe n being a downlink fixed subframe or a special subframe. Proposed is an uplink and downlink HARQ sequential relationship for a dynamic uplink and downlink subframe distribution solution, so that a dynamic TDD system can transmit uplink and downlink data.

Abstract: The present application relates to the field of wireless communications, and in particular, to an indication method and device for a modulation coding scheme. It is for solving the problem that in an existing LTE/LTE-A system, a higher-order modulation scheme cannot be supported, thereby limiting the further improvement of throughput in an application scenario of a high signal-to-noise ratio. The method of the embodiments of the present application includes: according to the channel quality and a first MCS table, a network side determining an MCS level corresponding to a channel scheduled for a UE; and by means of first indication information, notifying the UE of the determined MCS level, so as to indicate to the UE to determine a modulation scheme and code rate for the channel scheduled therefor according to the MCS grade, wherein there are at least corresponding entries of MCS indexes and TBS indexes corresponding to modulation schemes at higher modulation orders than 6 in the first MCS table. The embodiments of the present application introduce a higher-order modulation scheme into an existing LTE/LTE-A system, improving the spectrum efficiency.

Abstract: An embodiment of the invention relates to wireless communication technical field, especially relates to a method and device for performing interference control to reduce crossed time slot interference in Time Division Duplex (TDD) networking. The method of embodiment of the present invention comprises: network side device determines service load parameter value of each cell and the measurement parameter between the base stations which random two cells belongs to; For the two cells, said network side device determines an interference control threshold according to the service load parameter value of the two cells, and compares the determined said measurement parameter with said interference control threshold, and performs cluster partition according to the comparing result. Said network side device performs interference control according to the partitioned cluster. Because the factor of cell service load is considered in performing TDD crossed time slot interference control, thus the crossed time slot interference in TDD networking is reduced.
