Specific embodiment

In 5G new wireless (New Radio, NR) system, the resource allocation of PUCCH needs to consider respectively to be initially accessed rank Section and wireless heterogeneous networks (Radio Resource Control, RRC) connect latter two scene.After the rrc connection is established, lead to The two-stage indicating means of dynamic DCI signaling is added frequently with RRC signaling, RRC signaling is used to indicate a resource collection (resource set), and DCI signaling is used to indicate the resource index (resource index) in resource collection.But It is that, in user equipment (User Equipment, UE) initial access phase, the instruction of RRC signaling, the embodiment of the present application do not mention A kind of method that instruction is combined based on system information RMSI and DCI, message 4 of the notice UE in initial access phase are supplied PUCCH resource, flexibly reasonable PUCCH resource can be effectively realized using this method and indicated.

In the technological system of 5G NR, can there are two types of PUCCH resource indicating means, one is dominant indicating means, It is exactly the resource set for first indicating UE mono- distribution with RRC signaling, then notifies mono- specific resource of UE with DCI again index；Another method is recessive resource indicating mode, the method for exactly continuing to use LTE, corresponding the smallest with PDCCH In the call number index demapping of CCE to a specific PUCCH resource.Two methods respectively have advantage and disadvantage, and dominant method is more Add flexibly, recessive method can save signaling overheads.

In the PUCCH resource instruction of the message 4 of initial access, PUCCH resource collection can be indicated with RMSI information It closes, a resource index in instruction resource collection is then combined with DCI and recessive instruction.For example, PUCCH resource collection Closing includes 14 PUCCH resources, and the recessive instruction using 3 bits plus 1 bit goes to determine in PUCCH resource set one PUCCH resource.If carrying out recessive instruction using the minimum CCE index of PDCCH, in order to distinguish 16 PUCCH resources, then not Can be identical there are two the CCE index of UE or identical to CCE index progress odd even mapping, because 3 bits can only distinguish 8 Subset of resources, CCE index must complete the instruction of the resource in last subset of resources.In order to which more flexible carry out resource refers to Show, a kind of more effective implementation can be used as using the 4 bit resources instruction of complete dominance.The embodiment of the present application is sufficiently answered Dynamic instruction is completed with DCI, avoids resource contention and waste.

The embodiment of the present application provides a kind of indicating means for relying on RMSI and carrying out PUCCH parameter or resource.Following An example is provided in table 1, the PUCCH set of RMSI instruction includes 16, and every a line corresponds to a kind of configuration and corresponding resource Set, each set include 16 resources.PUCCH parameter in each set indicates determination by parameter corresponding in a line, can To include one of following content or combine: PUCCH format (format), PUCCH primary sign, PUCCH symbolic number (length), PRB offset (deviant), PUCCH minimum cyclic shift gap (minimal circulation shift intervals).Minimal circulation Shift intervals are determined for the number of resources of PRB carrying, because cyclic shift CS 12 in total that a PRB contains, If being divided into 3, then 4 resources of reusable are on a PRB.

Table 1

The embodiment of the present application provides PUCCH resource instruction and determines method, it is alternatively possible to for being initially accessed rank The resource instruction of section, main principle are that the physical uplink link comprising 16 PUCCH resources is indicated using RMSI information Then control channel (Physical Uplink Control Channel, PUCCH) resource collection is controlled with the downlink of 4bit Information (Downlink Control Information, DCI) indicates information, indicates a specific resource in resource collection Index.

In technical solution provided by the embodiments of the present application, an individual DCI information field can be used, or using multiple DCI information field joint instructions by remaining minimum system information (Remaining Minimum System Information, RMSI) the PUCCH resource index in the resource collection determined.

In technical solution provided by the embodiments of the present application, the resource index of PUCCH can be indicated by the PUCCH resource of DCI Domain and the instruction of 1 bit recessive information are combined into final resource index.For example, 1 bit indication information is used to indicate the jump of PUCCH Frequency pattern, corresponding 8 resource indexes of each frequency pattern, then indicated with 3 bit DCI.The bit recessive information by PDCCH most Indicated by small CCE index index.Recessive information bit can be in a high position for 4 bits, can also be in the low level of 4 bits；Recessiveness letter The partial information that the use of breath can be used alone PUCCH can also be indexed with joint instructions PUCCH resource.

It also include the dominant indicating means of DCI instruction in technical solution provided by the embodiments of the present application.

Indicate 16 PUCCH resources it is, for example, possible to use an individual 4 bit DCI information field, DCI bit information and PUCCH resource index corresponds；This individual 4 bit information domain can be dedicated PUCCH information instructions field either The information field shared with other information time domain.

For another example 16 PUCCH resources of multiple DCI information field joint instructions can also be used to index, multiple DCI information Domain includes the combination in the PUCCH specific information domain of 3 bits and the other information domain of 1 bit or multiple other information domains.

The concrete example explanation of several embodiments is given below:

Embodiment 1: using the low level of the DAI information of 2 bits, or high-order 1 bit and dedicated 3 bit combination are at 4 ratios Special PUCCH resource indicates information.In initial access phase, since descending scheduling signaling indexes (Downlink Assignment Index, DAI) this information field is not used in special-purpose, therefore can be used for PUCCH resource instruction.

Embodiment 2: letter is indicated at the PUCCH resource of 4 bits using 1 bit information and dedicated 3 bit combination of DAI Breath reuses the initial position of other 1 bit DAI information instruction PUCCH.For example, when the time domain length of PUCCH is 2 symbols When, the DAI information of this bit be used to indicate when being 1 PUCCH primary sign be 10, DAI information be 0 be used to indicate PUCCH rise Beginning symbol 12.

Another purposes of this 1 bit (i.e. DAI) is that be used to indicate PUCCH primary sign be that 4 bits are signified in DCI Primary sign corresponding to the PUCCH resource shown, or the offset being fixed based on the primary sign.For example, if predetermined Fixed deviant is 2, when the corresponding primary sign of a PUCCH resource in 16 PUCCH resources of 4 bit indications is 12, then this additional DAI bit may indicate whether that keeping original primary sign is 12, or 2 symbols of offset, if Bit information position is 1, and instruction is offset, then primary sign is 12-2=10, and offset can be biased forwards certainly, is also possible to It deviates, can be preset according to actual needs backward.

There are also another purposes for this 1 bit (i.e. DAI), are used to indicate the Physical Resource Block (Physical of PUCCH Resource Block, PRB) position be PRB itself or base corresponding to PUCCH resource indicated by 4 bits in DCI In the offset that the PRB is fixed.For example, making a reservation for fixed deviant is 2, if in 16 PUCCH resources of 4 bit indications The corresponding PRB of a PUCCH resource be 2, if then 1 bit DAI instruction do not deviate, PRB be number be 2 PRB, such as Fruit has 2 RB of constant offset, then PRB is the PRB of number 2-2=0, and offset can be low frequency offset certainly, is also possible to height Frequency deviation is moved, and can be preset according to actual needs.

Embodiment 3: it indicates that 16 PUCCH resources index using multiple information fields, then is indicated with the remaining bits of information field One of parameter information, including following content of PUCCH or combination: cyclic shift (cyclic shift), orthogonal mask (cover Code OCC) index, the format (format) of PUCCH primary sign, PUCCH etc..

Further, it if the PUCCH resource set of RMSI instruction includes 16 or more resources, then needs more DCI information bit indicates PUCCH resource index.For example when a resource set includes 32 resources, then 5 bits are needed, at this time The instructions field of 5 bits is made of the PUCCH specific information domain of 3 bits and the DAI information bit of 2 bits；If when a resource When collection is comprising 64 resources, then 6 bits are needed, at this time by the HARQ information ratio in the PUCCH specific information domain of 3 bits and 3 bits The instructions field of spy's 6 bits of composition；HARQ (Hybrid Automatic Repeat request), hybrid automatic repeat-request are used In the instructions field of instruction retransmission process information, the instruction for PUCCH is borrowed at this time.

In technical solution provided by the embodiments of the present application, the correspondence of a kind of PUCCH resource index and OCC index is contained Method.For example, being format 1 when being divided into the fomat of 2, PUCCH between the minimal circulation displacement CS of configuration, a PRB can use 6 A cyclic shift { 0,2,4,6,8,10 }.Different OCC can be used in different PUCCH length, for example PUCCH symbolic number is 10 When, due to frequency hopping, OCC length can be 2 or 3, when symbolic number is 14, and OCC length can be 4 or 3.The generation of orthogonal sequence is such as Shown in following table 2.

Orthogonal sequence

Table 2

In formulaIn, N_SFIndicate that OCC spreading length, m indicate OCC sequence bits index,It indicates Phase value.I indicates OCC orthogonal mask index.In table 2Indicate spreading length.

Assuming that the reference signal of PUCCH and the minimum OCC length that uses of data are 2, as above when PUCCH symbolic number is 10 Shown in the table 2 in face, there are two OCC codes, in order to enable the interference between user becomes minimum, it is required that adjacent CS index couple Different OCC is answered, for example, { 0,4,8 } corresponds to OCC code 1, { 2,6,10 } correspond to OCC code 2, the OCC of CS two neighboring in this way Be it is orthogonal, can maximize inhibit user between interference.
