In existing LTE technical standard, carry out in the process of multi-upstream access at UE, the eNB of network side is that each user distributes respective special RNTI.If user has exclusive data to need to upload, the exclusive data dispatching command of this user adopts the special RNTI of user to carry out scrambling, the control command issued is configured in the private space of control channel unit (ControlChannelElements is called for short CCE).The private space of this CCE is determined by the RNTI that user is special.UE is when carrying out demodulation customer-specific data, by searching for the private space of CCE, scrambling detection is carried out with special RNTI, determine the Physical Downlink Shared Channel (PhysicalDownlinkSharedChannel distributed, be called for short PDSCH) physical address, and carry out corresponding PDSCH data demodulates spatially.
In existing LTE technical standard, for broadcast channel, to the same public RNTI of multiple cell configuration that an eNB controls.Particularly, the public RNTI in existing LTE system comprises system message RNTI (SystemInformationRNTI is called for short SI-RNTI) and beep-page message RNTI (PagingRNTI is called for short P-RNTI) etc.Because the scheduling of the data based on LTE technology is transmitted by PDSCH, therefore Physical Downlink Control Channel (PhysicalDownlinkControlChannel is called for short PDCCH) the public RNTI of general employing for sending system message and paging channel dispatching command carries out scrambling.Public dispatching command is configured in the public space of the CCE of Common Control Channel (CommonControlChannel is called for short CCCH), and UE searches for CCCH, decoding scheduling order, demodulates corresponding data from PDSCH.UE is when carrying out the public messages such as demodulating system message, beep-page message or other multiple users share message, by searching for public CCE space, carry out scrambling detection with public RNTI, determine the PDSCH physical address distributed, and carry out corresponding PDSCH data demodulates spatially.
In the trunking communication private network system set up based on above-mentioned existing LTE technical standard, the RNTI that user adopts comprises: P-RNTI, SI-RNTI, community RNTI (CellRNTI, be called for short C-RNTI), Stochastic accessing RNTI (RandomAccessRNTI, be called for short RA-RNTI), for the RNTI (TransmitPowerControl-PhysicalUplinkControlChannel-RNTI of Physical Uplink Control Channel transmitting power control, be called for short TPC-PUCCH-RNTI), for the RNTI (TransmitPowerControl-PhysicalUplinkSharedChannel-RNTI of Physical Uplink Shared Channel transmitting power control, be called for short TPC-PUSCH-RNTI) etc., on this basis, also add group RNTI (GroupRNTI, be called for short G-RNTI) and group page message RNTI (GroupPagingRNTI, be called for short GP-RNTI).According to above-mentioned existing LTE technical standard, for monitoring users arranges public RNTI, for speaker user arranges special RNTI, therefore, for realizing the semi-persistent scheduling (Semi-persistentSchedule in private network system, be called for short SPS) scrambling in process, such as scrambling is carried out to SPS activation command and scrambling etc. is carried out to the order of SPS data retransmission, also need to increase semi-persistent scheduling community RNTI (Semi-persistentSchedule-Cell-RNTI is called for short SPS-C-RNTI).
In UE, because the calculation processing power of the processor manufacturing UE has certain limit, therefore UE can only process the RNTI of finite number.In the private network system adopting above-mentioned existing LTE technical standard to set up, each UE needs the value volume and range of product of RNTI to be processed various, causes the processor of UE to need to carry out the calculation process of large amount of complex, therefore causes the poor reliability of communication process.
