In step 203, judge whether the content of the descending distribution of SPS-G-RNTI mark indicates release, if then proceed to step 205, otherwise proceeds to step 206.
In step 204, judge whether this TTI has configured the descending distribution of SPS-G-RNTI mark, if then proceed to step 208, otherwise process ends.
In step 205, when step 203 judges that the content of the descending distribution that SPS-G-RNTI identifies is instruction release, remove the descending distribution of the SPS-G-RNTI mark of configuration.
In step 206, when step 203 judges that the descending distribution that SPS-G-RNTI identifies is not instruction release, then store the descending descending distribution distributed as the SPS-G-RNTI mark configured of SPS-G-RNTI mark.
In step 207, judge whether the descending distribution of the SPS-G-RNTI mark configured indicates at this TTI downlink data receiving, is proceed to step 208, otherwise process ends.

(10*SFN+subframe)=[(10*SFNstart_time+subframestart_time)+N*trunkSemiPersistSchedIntervaDL]modulo10240
Wherein, N be more than or equal to 0 integer, SFNstart_time and subframestart_time represents initialization respectively or reinitializes System Frame Number corresponding to this TTI of descending distribution of SPS-G-RNTI mark of configuration and subframe numbers, and trunkSemiPersistSchedIntervaDL represents collection cluster downlink semi-static scheduling cycle.N means in initialization or reinitializes TTI corresponding to the subframe of descending distribution of SPS-G-RNTI mark of configuration when equaling 0, the descending distribution of the SPS-G-RNTI mark of this configuration also indicates UE downlink data receiving.
In step 208, receive the TB on DL-SCH according to the instruction of the descending distribution of the SPS-G-RNTI mark configured and decode.
In step 209, after TB is successfully decoded, demultiplexing MAC PDU.
In step 210, judge that the logic channel of the MAC head instruction of the MAC PDU after demultiplexing is as TCCH or TTCH.
In step 211, if the logic channel of MAC head instruction is TCCH, then the MAC SDU of this MAC head correspondence is transferred to high level and carries out signaling resolution.
In step 212, if the logic channel of MAC head instruction is TTCH, then the MAC SDU of this MAC head correspondence is transferred to high level and carries out business data processing.
Wherein, step 210,211 and 212 is preferred mode, and these three steps also may instead be: after TB is successfully decoded, demultiplexing MAC PDU, and the MACSDU obtained is delivered to high level.
It should be noted that, MAC PDU may comprise multiple MAC head, so step 210,211 and 212 needs the number of times that repeats identical with MAC head number.
