    摘要： A framing method of the common interleaved frame is provided, which includes the following steps: obtaining the position information of each sub-channel in the common interleaved frame; depositing data bits in each sub-channel accordingly based on the position information of each sub-channel and the number of bits comprised in the capacity unit CU; wherein the number of bits comprised in the CU is determined by a symbol mapping mode of each sub-channel. The method can help the skilled in the art to make a CIF with the data bits at the transmitter of the T-MMB system. A framing device of the common interleaved frame is also provided in the present invention.

    摘要： The present invention discloses a method and device for power saving, receiving the hibernation instruction sent by the network side, one or multiple hardware units inside a station (STA) are turned off to allow the STA to enter a hibernation mode; When STA receives a service instruction from the network side or when the STA has data to be transmitted to a central access point (CAP) of the network side, all the hardware units turned off are turned on to allow the STA to terminate the hibernation mode. Application of the present invention allows within a certain period for a STA remain at a minimal power state, thus conserving power and air interface resources.
