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 distribution technology in the 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, can be furnished with different radio network temporary identifier (RNTI) for different business, such as concerning system broadcast message, being furnished with the interim identification marking of system information wireless network (SI-RNTI), paging channel can configure the interim identification marking of pager wireless net network (P-RNTI), can there be the interim identification marking of random access radio network (RA-RNTI) in the uplink random access, and the interim identification marking of cell-radio network (C-RNTI) of meeting configure user special use is used for the operations such as user's specific schedule order scrambling concerning the user of general access.In former LTE standard agreement, except the above-mentioned RNTI that mentions, also has the interim identification marking of interim 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) (activation and the SPS that are used for SPS pass the number re-transmission according to the scrambling of order).
In the private network system based on LTE, the RNTI that in former LTE standard, supports, the G-RNTI and the GP-RNTI that support group service have additionally been increased.G-RNTI is mainly used in the SPS activation command of descending group, the dispatching command scrambling that the scrambling of descending group control channel GCCH dispatching command is relevant with the up speaker of group user data SPS etc.GP-RNTI mainly is the paging for group user.
The descending control command of the scrambling of above-mentioned RNTI, can be divided into specific command and public order, the space that the control command of RNTI scrambling is occupied on control channel resource CCE (Control Channel Elements) is 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 a plurality of common command, the control command of user's special use is placed on the private space, private space can be that a plurality of users share, also can specially be enjoyed by a user, but this private space is the RNTI that distributes with the user to be bound, and the corresponding CCE of the C-RNTI/Temporary C-RNTI search volume that different user distributes may be overlapping.
In the former LTE agreement, SI-RNTI, P-RNTI, RA-RNTI, TPC-PUCCH-RNTI, TPC-PUSCH-RNTI are that a plurality of users share, so the order of their scramblings generally is to be placed on the public space of CCE, and Temporary C-RNTI and C-RNTI mainly distribute to single user, are specially enjoyed by unique user.Dispatching command to user's dedicated service generally is placed on the determined space with user-dependent C-RNTI/Temporary C-RNTI.G-RNTI and GP-RNTI for the private network setting, GP-RNTI is mainly to the scrambling of the paging command of supporting group service, the paging command of GP-RNTI scrambling generally is placed on public CCE search volume, and G-RNTI although to be a plurality of users share, but G-RNTI can be placed on the public search space of CCE, also can be placed on special-purpose CCE search volume.Public CCE search volume is from fixation of C CE spatial index 0, and terminal is from the determined original position of C-RNTI/Temporary C-RNTI to the search of private space.
Terminal is searched for the decoding scheduling order to Common Control Channel (Common Control Channel), demodulates corresponding public shared data from common control channel makes the downlink physical shared channel (Physical Downlink Shared CHannel) of appointment.If the user has exclusive data to pass, user's exclusive data dispatching command adopts C-RNTI (the perhaps Temporary C-RNTI of user's special use, G-RNTI) carry out scrambling, and issuing of control command is to be placed on and special-purpose physics CCE space that C-RNTI (perhaps Temporary C-RNTI, G-RNTI) binds mutually.
GP-RNTI mainly carries out scrambling to the paging command of supporting group service, and the order of GP-RNTI scrambling generally is placed on CCE Common Control Channel space.G-RNTI generally is used for: the scrambling of the control channel GCCH of group service, the scrambling of the descending SPS of group activation command, the scrambling of up speaker user's up SPS activation/deactivation order, the perhaps scrambling of dynamic dispatching order.
To the group service order of the descending scrambling of G-RNTI, the CCE space that both can be placed on user's special use also can be placed on public CCE space, and public space can there are the following problems if the order of G-RNTI scrambling is placed on:
Because GP-RNTI, SI-RNTI, P-RNTI, RA-RNTI, TPC-PUCCH-RNTI, the TPC-PUSCH-RNTI order generally is to 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 occurs more frequent, and on public space, 16 CCE can only carry at most 4 common command, public resource is relatively 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 the private space, then can additionally 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 the private space, according to former LTE protocol definition, the extra complexity that increases 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 to provide the collocation method in a kind of descending scheduling order space, and the method can strengthen the system gain of private network business, reduces the complexity of UE search G-RNTI.
In order to achieve the above object, the technical scheme of the present invention's proposition is:
The collocation method in a kind of descending scheduling order space, the method may further comprise the steps:
A, in current scheduling subframe, the default radio network temporary identifier G-RNTI of a group extending space;
B, base station determine that according to default professional dispatching priority order current each professional dispatching command takies the priority of public space;
C, take the priority of public space according to described each professional dispatching command, judge that described public space is whether shared by other professional dispatching commands higher than the priority of the dispatching command of G-RNTI scrambling, if so, then utilize described G-RNTI extending space to send the dispatching command of described G-RNTI scrambling to user equipment (UE); Otherwise, utilize described public space to send the dispatching command of described G-RNTI scrambling to described UE;
D, described UE search for the dispatching command of described G-RNTI scrambling according to the concurrent situation of group control channel GCCH and group service channel GTCCH at described public space or described G-RNTI extending space.
