To make the object, technical solutions and advantages of the present invention clearer, the present invention is made with reference to the accompanying drawing further
Detailed description.
It is succinct and intuitive in order to what is described, hereafter by describing several representative embodiments come to side of the invention
Case is illustrated.A large amount of details is only used for helping to understand the solution of the present invention in embodiment.However, it will be apparent that of the invention
Technical solution can be not limited to these details when realizing.In order to avoid unnecessarily having obscured the solution of the present invention, Yi Xieshi
It applies mode not described meticulously, but only gives frame.Hereinafter, " comprising " refers to " including but not limited to ", " root
According to ... " refer to " according at least to ..., but be not limited to according only to ... ".Due to the speech habits of Chinese, hereinafter without spy
When not pointing out the quantity of an ingredient, it is meant that the ingredient is either one or more, or can be regarded as at least one.
In actual networking, there are such scenes: have a pair of of FDD carrier wave, there are one or multiple pure uplinks load
Wave.The carrier wave of pure uplink can be the carrier wave or unauthorized carrier wave of authorization.UE executes uplink and sends on unauthorized carrier wave
Less to existing business interference on carrier wave, therefore such carrier wave can be used as pure up-link carrier, is served only for uplink transmission.
In actual service application, in many scenes, there are the business demands that video uploads, and the business demand is to cell
The demand of interior upstream bandwidth is far longer than the demand to downlink bandwidth.For actual networking scene and service application scene, need
Solve how to need using upstream bandwidth in cell in 1 pair of FDD carrier wave and the carrier wave of one or more pure uplinks solution practical application
Ask the problem of being far longer than downlink bandwidth demand.
In the big bandwidth demand of uplink uploaded for video and practical networking scene, 1 pair of available FDD carrier wave and 1 or more
The situation of a available pure up-link carrier, a kind of special FDD cell can be established in LTE system: the cell includes a pair
FDD carrier wave and one or more pure up-link carriers.In cell in a pair of FDD carrier wave, descending carrier is this special FDD cell
In unique descending carrier, up-link carrier is the uplink main carrier of this special FDD cell.All pure uplinks carry in the cell
Wave is the upstream auxiliary carriers of this cell.In this special FDD cell, using FDD frame structure: unique descending carrier and
Each up-link carrier all uses FDD frame structure.It is small to execute common FDD in an identical manner for unique descending carrier in the cell
The institute of descending carrier is functional in area, and unique uplink main carrier executes common FDD cell in an identical manner in the cell
The institute of interior up-link carrier is functional.
Accessing the UE of this special FDD cell, there are two types of types:
(1) common UE: these UE execute each function of UE in common FDD cell in the same manner.For these UE,
The cell is exactly a common FDD cell, which is only made of a pair of of FDD carrier wave: the relevant uplink of UE is sent in uplink
It is executed on main carrier, the relevant downlink transmission of UE is executed by unique descending carrier.These UE do not know that the cell is deposited
In other upstream auxiliary carriers.
(2) it supports UE (new UE): this kind of UE of special LTE-FDD cell to report when accessing cell and supports special FDD
The ability of cell.If the cell of such UE access is common FDD cell, eNodeB ignores the capability reporting；If such UE connects
The cell entered is special FDD cell, and eNodeB distributes up-link carrier to such UE according to the capability reporting: can be only to UE points
With uplink main carrier, multiple up-link carriers can also be distributed simultaneously to UE, these carrier waves may include uplink main carrier or not wrap
Include uplink main carrier.For this kind of UE, after accessing special FDD cell, eNodeB is carried UE when distributing resource to UE
The instruction of special FDD cell, or indicate that current area is that special FDD is small in a manner of implying the up-link carrier of distribution
Area, such as: some up-link carrier and descending carrier of distribution are not the carrier waves of pairing.
However, needing the technology for solving how to dispatch UE on each up-link carrier for this special LTE-FDD cell
Problem.The application provides solution for the above problem in special LTE-FDD cell.
In common LTE-FDD cell, can distributing dynamic PUSCH resource or SPS to UE on up-link carrier, (half is quiet
State) PUSCH resource.Correspondingly, C-RNTI (Cell Radio Network is temporarily identified to UE distribution cell-radio network
Temmporary Identify) or semi-static SPS (Semi-Persistent Scheduling) C-RNTI.UE detects C-
The scrambled PDCCH of RNTI or SPS C-RNTI obtains dynamic or the scheduling information of SPS PUSCH.It, may in special FDD cell
Give above-mentioned new UE to configure multiple up-link carriers, when be used on PDCCH dispatching uplink carrier resource DCI format (DCI format 0 or
DCI format 4) when not carrying carrier wave instructions field, how on UE instruction PDCCH up-link carrier scheduled in DCI format is desirable
It solves the problems, such as.By distributing different C-RNTI or SPS C-RNTI to different up-link carriers, eNodeB makes the applicant
Dynamic PUSCH or semi-static PUSCH money on the carrier wave is dispatched with the dedicated C-RNTI or SPS C-RNTI of corresponding up-link carrier
Source is to solve the problems, such as this.
Specifically, for this problem, in the special FDD cell of one kind of the invention up-link carrier dispatching method, comprising:
For accessing the UE of special FDD cell, if UE reports the ability for supporting special FDD cell, eNodeB is according to the energy of UE
Power is reported to UE collocating uplink carrier wave.For being allocated to each up-link carrier of UE, to distribute dynamic PUSCH on the carrier wave to UE
Or SPS PUSCH resource, C-RNTI the or SPS C-RNTI of the carrier wave is configured to UE.C-RNTI the or SPS C- of the carrier wave
The scrambled PDCCH of RNTI is used to dispatch dynamic PUSCH or SPS the PUSCH resource on the up-link carrier to UE.Distribute to UE's
C-RNTI on same up-link carrier is different from SPS C-RNTI, distributes to C-RNTI or SPS on each up-link carrier of UE
C-RNTI is different.
Based on above-mentioned analysis, Fig. 1 is the stream according to the dispatching method of up-link carrier in the special LTE-FDD cell of the present invention
Cheng Tu.Wherein, special LTE-FDD cell includes a pair of FDD carrier wave, and a pair of of FDD carrier wave includes that uplink main carrier and downlink carry
Wave, special LTE-FDD cell further include the upstream auxiliary carriers of at least one；The auxiliary load of uplink of uplink main carrier and at least one
Wave is all up-link carrier.

Step 101:UE reports the wireless capability message of UE to eNodeB, carries in the wireless capability message of UE and supports spy
The ability information of different LTE-FDD cell.
Herein, it supports the UE of special FDD cell after accessing cell, the nothing of UE is reported during UE capability reporting
Line ability information carries the ability information for supporting special FDD cell in the wireless capability message of UE.Support special FDD
It is carried in the ability information of cell: supporting the instruction of special FDD cell.TRUE is designated as when the special FDD cell of support
When, support the band information that the special FDD cell of UE support is also carried in the ability information of special FDD cell.
Step 102:eNodeB is that UE configures one or more up-link carriers, and will configure according to the wireless capability message of UE
UE is sent to the configuration information and descending carrier configuration information of one or more up-link carriers of UE.
Herein, the UE of the FDD cell special for support, eNodeB is according to the wireless capability message of UE in UE configuration
Row carrier wave, and the configuration information of each up-link carrier for being allocated to UE and the configuration information of descending carrier are passed through into dedicated signaling
It is sent to UE.
Wherein, the configuration of up-link carrier is divided to two kinds of scenes:
Scene 1: when UE special FDD cell uplink main carrier initiate random access, pass through the random access procedure
When accessing special FDD cell, eNodeB carries interim (Tempary) C-RNTI in the random access response for being sent to UE,
UE is saved after random access procedure contention resolved using Tempary C-RNTI as C-RNTI, and accessed small
The scrambled PDCCH of C-RNTI is monitored on the descending carrier in area.
Scene 2: when UE special FDD cell some upstream auxiliary carriers initiate random access, pass through the random access
When process accesses special FDD cell, eNodeB carries Tempary C-RNTI, UE in the random access response for being sent to UE
After random access procedure contention resolved, saved using Tempary C-RNTI as C-RNTI, and in accessed cell
Descending carrier on monitor the scrambled PDCCH of C-RNTI.
In above two scene, the scrambled PDCCH of C-RNTI carries the lower Mobile state PDSCH of descending carrier in cell
