Abstract
The invention provides a downlink scheduling command space configuration method, which is characterized in that a G-RNTI (group radio network temporary identifier) extended space is reserved or extended; and under the situation that a public space is occupied by other RNTIs (radio network temporary identifiers) with higher priorities, a G-RNTI is placed in the G-RNTI extended space. Therefore, the system gain of private network service can be enhanced and the complexity of searching for the G-RNTI by UE (user equipment) is reduced.
Description
Technical field
The present invention relates to the resource configuration technology in mobile communication system, particularly relate to the collocation method in the descending scheduling order space of private network business.
Background technology
In current LTE technical standard, different radio network temporary identifiers (RNTI) can be furnished with for different business, such as can be furnished with the interim identification marking of system information wireless network (SI-RNTI) concerning system broadcast message, paging channel can configure the interim identification marking of pager wireless net network (P-RNTI), the interim identification marking of random access radio network (RA-RNTI) can be there is in uplink random access, the special interim identification marking of cell-radio network (C-RNTI) of configure user is understood for operations such as user's specific schedule order scramblings concerning the user of general access.In former LTE standard agreement, except the above-mentioned RNTI mentioned, also has the interim identification marking of Temporary Cell Radio Network (Temporary C-RNTI), the interim identification marking of transmission power control ascending physical signal control channel wireless network (TPC-PUCCH-RNTI), the interim identification marking of transmission power control ascending physical signal shared channel wireless network (TPC-PUSCH-RNTI), the interim identification marking of semi-persistent scheduling cell-radio network (SPS-C-RNTI) (pass number for the activation of SPS and SPS and retransmit scrambling according to order).
Based in the private network system of LTE, except the RNTI supported in former LTE standard, adds additional G-RNTI and GP-RNTI supporting group service.G-RNTI is mainly used in the SPS activation command of descending group, the dispatching command scrambling etc. that the scrambling of descending group control channel GCCH dispatching command is relevant with up group speaker user data SPS.GP-RNTI is mainly used for the paging of group user.
The descending control command of the scrambling of above-mentioned RNTI, specific command and public order can be divided into, the space that the control command of RNTI scrambling is occupied on control channel resource CCE (Control Channel Elements) to be divided into Common Control Channel space and Dedicated Control Channel space, public control command is placed on the public space of CCE, and public space is shared by multiple common command, the special control command of user is placed on private space, private space can be that multiple user shares, also specially can be enjoyed by a user, but this private space is the RNTI distributed with user is binding, the CCE search volume corresponding to C-RNTI/Temporary C-RNTI that different user distributes may be overlapping.
In former LTE protocol, SI-RNTI, P-RNTI, RA-RNTI, TPC-PUCCH-RNTI, TPC-PUSCH-RNTI are that multiple user shares, so the order of their scramblings is generally be placed on the public space of CCE, and Temporary C-RNTI and C-RNTI mainly distributes to single user, specially enjoyed by unique user.The dispatching command of user's dedicated service is generally placed on and the user-dependent determined space of C-RNTI/Temporary C-RNTI.For G-RNTI and GP-RNTI that private network is arranged, GP-RNTI is mainly to the scrambling of the paging command of support group service, the paging command of GP-RNTI scrambling is generally placed on public CCE search volume, although and G-RNTI be multiple user share, but G-RNTI can be placed on the public search space of CCE, special CCE search volume also can be placed on.Public CCE search volume is from fixation of C CE spatial index 0, and the search of terminal to private space is from the determined original position of C-RNTI/Temporary C-RNTI.
Terminal carries out the order of search decoding scheduling to Common Control Channel (Common Control Channel), makes the downlink physical shared channel (Physical Downlink SharedCHannel) of specifying demodulate corresponding public shared data from common control channel.If user has exclusive data to pass, C-RNTI that the exclusive data dispatching command of user adopts user special (or Temporary C-RNTI, G-RNTI) scrambling is carried out, and issuing of control command is placed on the special physics CCE space of binding mutually with C-RNTI (or TemporaryC-RNTI, G-RNTI).
GP-RNTI is mainly to supporting that the paging command of group service carries out scrambling, and the order of GP-RNTI scrambling is generally placed on CCE Common Control Channel space.G-RNTI is generally used for: the scrambling of the control channel GCCH of group service, the scrambling of descending group SPS activation command, the scrambling of the up SPS activation/deactivation order of up speaker user, or the scrambling of dynamic dispatching order.
To the group service order of the descending scrambling of G-RNTI, both can be placed on the special CCE space of user and also can be placed on public CCE space, if the order of G-RNTI scrambling is placed on, public space can there are the following problems:
Due to GP-RNTI, SI-RNTI, P-RNTI, RA-RNTI, TPC-PUCCH-RNTI, TPC-PUSCH-RNTI order is generally be placed on the public space of CCE, and the shared CCE size of public space only has 0 ~ 15 to amount to 16 CCE spaces, these common command RNTI occur relatively more frequent, and on public space, 16 CCE can only carry at most 4 common command, public resource is more nervous, G-RNTI and these RNTI must seize this public space, like this, will reduce the throughput of system.
If G-RNTI is placed on private space, then additionally can increase the complexity of the search volume of UE, originally the maximum search number of times of UE is 44 times, if G-RNTI is placed on private space, define according to former LTE protocol, the complexity of extra increase is 32, and the complexity of increase is higher, is a larger requirement to the battery capacity of UE.
Summary of the invention
In view of this, main purpose of the present invention is the collocation method providing a kind of descending scheduling order space, and the method can strengthen the system gain of private network business, reduces the complexity that UE searches for G-RNTI.
