Frame；Other subframes are used for the communication between terminal and base station as usual.
Assuming that a total of 8 standard process resources of terminal inner, standard process resource described herein includes memory.Each
The corresponding memory of standard process resource can completely be deposited in the case where not carrying out stamp operation to the corresponding data of process
Store up the corresponding data of each process.Stamp is to give up a part of data, specifically how to give up a part of data, can pass through speed
Rate matches to realize.

The number of link DL.The number of the DL at this time is above-mentioned first down link data.The DL is the contracting of Downlink
It writes, corresponding Chinese is downlink.
If the data of the DL are X, by calculating it is found that having accounted for buffer size/8 × X of memory at this time；It is remaining
Buffer size is buffer size/8 × (8-X).Herein, total memory that the buffer size is indicated.
Process distribution is carried out to buffer size/8 × (8-X), as an illustrative example two the first D2D communications and the 2nd D2D
Downlink transmission is Y between communication, then carries out Y+1 equal part to free memory.The Y is equal to 2 according to table 2, then will remain
Remaining buffer size/8 × (8-X) carries out 3 equal parts.
