Abstract

The invention discloses a feedback resource distribution method and system for TDD (Time Division Duplexing) downlink multi-subframe scheduling. The core concept of the feedback resource distribution method and system is that eNB specially configures PUCCH (Physical Uplink Control Channel) resources for ACK/NACK feedback during downlink multi-subframe scheduling in each uplink subframe for UE (User Equipment). One solution is that the PUCCH resources are configured for each piece of UE in the uplink subframe; another solution is that a plurality of shared PUCCH resources are configured for multiple pieces of UE in the uplink subframe, and then a PUCCH resource indication domain is defined in a PDCCH (Physical Downlink Control Channel) for indicating one of the PUCCH resources. According to the feedback resource distribution method and system, the PUCCH resources special for the ACK/NACK feedback during the downlink multi-subframe scheduling are configured for the UE in the uplink subframe, so that the conflict of the PUCCH resources during the ACK/NACK feedback in the multi-subframe scheduling mode can be avoided.

Embodiment
Below in conjunction with drawings and Examples, embodiments of the present invention are described in further detail.Following examples only for illustration of the present invention, and can not be used for limiting the scope of the invention.
It should be noted that, for brevity, for the ins and outs that embodiment before has been set forth, may will repeat no more in embodiment afterwards; Otherwise the ins and outs set forth in embodiment afterwards, embodiment before also may not set forth.But it should be appreciated by those skilled in the art that only otherwise form conflict, the ins and outs that embodiment describes are applicable to other embodiment too.
Core concept of the present invention is eNB is the PUCCH resource that UE is configured for feeding back ACK/NACK when there is descending many subframe schedulings specially in each sub-frame of uplink, and a kind of scheme is for each UE configures PUCCH resource in each sub-frame of uplink; Another kind of scheme is for multiple UE configures multiple shared PUCCH resource in each sub-frame of uplink, is then that the PUCCH instructions field of each UE definition n-bit indicates one of them PUCCH resource in PDCCH.
First the first scheme is described.The position of many subframes descending scheduling mandate and scheduling sublayer number of frames are not carried out to situation about limiting, the binding window feedback sequential that ACK/NACK still determines according to uplink-downlink configuration in TDD is fed back, and its PUCCH resource used is configured by radio resource control (RRC) high-level signaling.Have 7 kinds of uplink-downlink configuration in TDD, as shown in table 1, wherein D represents descending sub frame, and U represents sub-frame of uplink, and S represents special subframe, wherein also includes downlink data.
For TDD uplink-downlink configuration 0 and 6, because an a sub-frame of uplink only corresponding descending sub frame, therefore, high-rise configuration 1 PUCCH resource.For uplink-downlink configuration 5, adopt Rel-8 binding mode, feeding back ACK/NACK, therefore only need configure 1 PUCCH resource.In one embodiment, the concrete distribution method of feedback resources for many subframe schedulings of each uplink-downlink configuration is as follows: for uplink-downlink configuration 0, eNB configures 1 PUCCH resource each sub-frame of uplink for each UE, and then UE uses PUCCH format 1a/1b feeding back ACK/NACK in the resource of correspondence;
For uplink-downlink configuration 1, eNB is that each UE configures 1 PUCCH resource at each sub-frame of uplink, then UE uses PUCCH format 1a/1b feeding back ACK/NACK in the resource of correspondence, for M=2, UE adopts AND-operation when feeding back ACK/NACK to the ACK/NACK of two transmission blocks (TB), i.e. space binding, the ACK/NACK of each subframe feedback 1bit.And M=1 does not adopt space to bind;
For uplink-downlink configuration 2, eNB is that each UE configures 4 PUCCH resource at each sub-frame of uplink, then UE uses the PUCCH format 1b feeding back ACK/NACK of band Channel assignment in the resource of correspondence, be the situation of 2 for binding window size, for reducing the PUCCH resource of configuration, if transmission mode supports 2 transmission blocks (TB), space will be adopted to bind, and then use PUCCH format 1b to feed back;
Be that each UE configures 3 PUCCH resource for uplink-downlink configuration 3, eNB at each sub-frame of uplink, then UE uses the PUCCH format 1b feeding back ACK/NACK of band Channel assignment in the PUCCH resource of correspondence;
Be that each UE configures 4 PUCCH resource for uplink-downlink configuration 4, eNB at the PUCCH of each sub-frame of uplink, then UE uses the PUCCH format 1b feeding back ACK/NACK of band Channel assignment in the PUCCH resource of correspondence;
Be that each UE configures 1 resource for uplink-downlink configuration 5, eNB at the PUCCH of each sub-frame of uplink, then UE uses PUCCH format 1a/1b feeding back ACK/NACK in the PUCCH resource of correspondence by Rel-8 mode;
Be that each UE configures 1 resource for uplink-downlink configuration 6, eNB at the PUCCH of each sub-frame of uplink, then UE uses PUCCH format 1a/1b feeding back ACK/NACK in the PUCCH resource of correspondence.
Table 1TDD uplink-downlink configuration table
This scheme corresponding, propose the feedback resource allocation system of the descending many subframe schedulings of a kind of TDD, in one embodiment, this system comprises base station eNB and multiple terminal UE:
Described eNB, for uplink-downlink configuration 0,1,5 or 6, for each UE configures 1 PUCCH resource at each sub-frame of uplink; For uplink-downlink configuration 2 or 4, for each UE configures 4 PUCCH resource at each sub-frame of uplink; Be that each UE configures 3 PUCCH resource at each sub-frame of uplink for uplink-downlink configuration 3, eNB;
Described UE, when receiving descending sub frame scheduling authorization, uses the PUCCH resource feeding back ACK/NACK of configuration at the sub-frame of uplink of correspondence.
Those skilled in the art can know, the ins and outs of this system embodiment and the embodiment of the method for the first string similar, therefore do not repeat them here.
The advantage of this allocation plan to reach the highest flexibility of many subframe schedulings, can transmit the mandate of many subframe schedulings, and can not cause PUCCH resource conflict at the PDCCH of any one descending sub frame.But shortcoming is that the PUCCH resource of configuration is more, and even without downlink data transmission, PUCCH resource still needs to reserve, thus causes PUCCH resource to waste.
In order to save PUCCH resource, propose another kind of scheme.Introduce the feedback resource distribution method of the many subframe schedulings according to another preferred embodiment of the present invention below.
In step S1, the PUCCH resource that configuration is shared, definition PUCCH resource instructions field.Being specially: in order to save PUCCH resource, needing the transmission location considering the mandate of many subframe schedulings, namely for many subframe schedulings, in subframe binding window, be limited to a rare mandate.It is that multiple UE shares that eNB configures multiple PUCCH resource in a sub-frame of uplink, and defines a PUCCH resource instructions field for each UE in the Downlink Control Information (DCI) of the PDCCH of row subframe in each of the lower;
In step S2, use PUCCH resource instructions field instruction PUCCH resource.Be specially: the PUCCH resource instructions field of this UE is set to specific value and indicates one of them or a pair PUCCH resource by eNB when sending the mandate of many subframe schedulings for one of them UE.
In step S3, use the PUCCH resource of instruction, feed back the A/N of many subframe schedulings.Be specially: when receiving descending many subframe schedulings mandate, UE uses by the PUCCH resource feeding back ACK/NACK of the current instruction of PUCCH resource instructions field of this UE at the sub-frame of uplink of correspondence.
If the size of PUCCH resource instructions field is n-bit, n is positive integer, so preferably the number of PUCCH resource or logarithm are no more than 2n, thus make each or often pair of PUCCH resource is corresponding with the binary digit that the PUCCH resource instructions field of n-bit arranges out.As preferably, the PUCCH resource that the PUCCH resource instructions field instruction that can define 2 bits for each UE in DCI uses, and eNB can configure 4 PUCCH resource for some UE in sub-frame of uplink shares, the binary digit 00,01,10,11 arranged out by 2 bit PUCCH resource instructions field indicates one of them or a pair PUCCH resource respectively.Bind for configuration and authorize not in the situation of the PDCCH transmission of last subframe of binding window, this resource of use is fed back ACK/NACK by UE.When binding window size is 4, when adopting the form 1b transferring ACK/NACK of PUCCH band Channel assignment, the PUCCH resource instructions field of each descending sub frame indicates a pair PUCCH resource, and initial CCE and second CCE for each descending sub frame indicates two other PUCCH resource.
Whether the descending allocation index DAI territory being configured with 2 bits in the PDCCH of Rel-8 and the later descending sub frame of the TDD of version loses to detect eNB mandate in binding situation.Therefore, as to the replacement defining PUCCH resource instructions field in DCI, eNB can specify not adopt binding pattern feeding back ACK/NACK, thus is used in the descending DAI territory of this 2 bit indicating the PUCCH resource being used for many subframe schedulings shared at multiple UE of sub-frame of uplink configuration.
This scheme corresponding, propose the feedback resource allocation system of the descending many subframe schedulings of a kind of TDD, in one embodiment, this system comprises base station eNB and multiple terminal UE:
Described eNB, be that multiple UE configures multiple shared PUCCH resource in each sub-frame of uplink, and define a PUCCH resource instructions field for each UE in the PDCCH of row subframe in each of the lower, when for using this PUCCH resource instructions field to indicate one of them or a pair PUCCH resource when one of them UE sends the mandate of many subframe schedulings;
Described UE, when receiving descending many subframe schedulings mandate, uses the PUCCH resource feeding back ACK/NACK of the current instruction of PUCCH resource instructions field of this UE at the sub-frame of uplink of correspondence.
Described PUCCH resource instructions field can be configured in the Downlink Control Information DCI of PDCCH.Now, the size of described PUCCH resource instructions field is n-bit, and the number of described multiple shared PUCCH resource or logarithm are not more than 2n.Preferably the size of described PUCCH resource instructions field is 2 bits, and number or the logarithm of described multiple shared PUCCH resource are 4.
In addition, described eNB, to detect eNB in binding situation, the situation of whether losing is authorized for the descending DAI territory being configured with 2 bits for each UE in the PDCCH of descending sub frame, can specify binding pattern feeding back ACK/NACK is not adopted for many subframe schedulings, and using the descending DAI territory of this 2 bit as described PUCCH resource instructions field.
Those skilled in the art can know, the embodiment of the method for the ins and outs of this system embodiment and second scheme is similar, does not therefore repeat them here.
First scheme is shared by multiple UE and has been saved PUCCH resource preferably for the mode of the PUCCH resource of feeding back ACK/NACK during many subframe schedulings, improves the service efficiency of PUCCH resource.
Above embodiment is only for illustration of the present invention, but not limitation of the present invention.Although with reference to embodiment to invention has been detailed description; but those of ordinary skill in the art is to be understood that; various combination, amendment or equivalent replacement are carried out to technical scheme of the present invention; do not depart from principle of the present invention and spirit, it all should be encompassed within the protection range of claim of the present invention.
