Embodiment two

The present embodiment is illustrated to the PUCCH forms used.

As shown in Figure 4, each PUCCH channels include multiple RB, the structure that each RB is used to PUCCH channel architecture It is still the existing PUCCH formats of original R13.

Wherein, the form that each RB is used can include following two：

The first：Predefined or base station high-level signaling is semi-statically configured some interleaving units and only includes a kind of format. That is, each RB format is identical, for example, be format2, is all either format2a or is all format2b, or Person is format 5, or is format4.

Second：Base station configures some interleaving units and includes a variety of format, and the form that different RB are used can be different.Example Such as, some RB of some interleave unit are format 1, and some RB are format 2, or some RB are using form 3, some RB Form 1 is used using form 2, or some RB, some RB use format 4 or form 5.

Base station can be by distributing between the transmission and various forms that different format realize different UCI bit numbers Switching.

Different UE are only capable of using identical form on identical RB, to realize that multi-user orthogonal is multiplexed.

Each UE indexes different frequency domain spread spectrum codes in frequency domain multiplexing and identical interleaving index by different interleaving, and/or Orthogonal convolutional code (Orthogonal Convolutional Code, referred to as OCC) carries out PUCCH in an intertexture resource Resource code division multiplexing.

Wherein, the UCI information of carrier-wave transmission can include at least one of：

The ACK/NACK of one multiple process of carrier wave or multiple subframes；The cycle CSI information of one or more carrier waves or Aperiodic CSI information；BSR；Additional bit is used for base station and UE keeps ACK/NACK to report synchronization.

UCI information process includes following two mode：

Mode one：First by UCI information blocks, a group may be finally mapped on multiple RB, and different groups are mapped to difference RB or pass through different format carryings.

Then the bit information that the UCI information each organized can be carried according to the corresponding forms of RB of mapping is carried out to information Code rate is matched, followed by scrambling, is modulated, mapping.

Mode two：UCI information is repeated to send on multiple RB.What each RB was used to UCI processing modes according to the RB Form is handled.

Embodiment three

The present embodiment only includes format 2/2a/2b one of which, or two kinds in format 2/2a/2b to PUCCH Or the situation of three kinds of forms is illustrated.

Each RB that the mode for predefining the high-rise RRC signaling configuration of mode or base station by system defines PUCCH is to adopt UCI processing is carried out with format 2/2a/2b processing mode.PUCCH structure is as shown in Figure 5.Each RB identicals A kind of form, all RB of such as one interleave unit are form 2, or are all form 2a or are all form 2b.Or Each RB uses different forms, and such as index uses format2 for 0 RB, indexes and uses format 2a, rope for 10 RB The RB for being cited as 20 uses format2b.

4 DMRS character positions are included using each subframes of form 2/2a/2b PUCCH, particular location is with existing Position is identical.

When UCI includes ACK/NACK, CQI, PMI, when the CSI information such as RI, it can be sent by format2/2a/2b Ascending control information.Specifying information processing procedure is as follows：

UCI information is divided into 10 groups, then each group is mapped to above different RB, each group according to RB correspondences Form carry out corresponding information processing, encode, scramble, modulation, then frequency domain is multiplied by a ZC sequence spread spectrum, is finally mapped to On one RB corresponding SC-OFDM symbols.

Wherein, the determination mode of the ZC sequences used in each RB is as follows：

Mode one：All RB ZC sequences are all identical.

Mode two：The root sequence of all RB ZC sequences is all identical, and the cyclic shift that each RB is used is different.

When multiple UE take identical RB and identical ZC root sequences, the cyclic shift of the ZC sequences used is not Together.

Mode three：Frequency expansion sequence used in all RB is obtained by same ZC sequence truncations.

For example, the sequence that PUCCH accounts for spread spectrum on 10 RB of an interleave unit, each RB is by same length 120 ZC sequences, are worth for N (0), N (1), N (2), and N (3) ... ... N (119) intercept different positions 12 are worth to.Interweave First RB of unit sequence is N (0)~N (11) of this sequence, and second RB sequence is N (12)~N (23), The rest may be inferred.

When UCI information is less than 10 bit, processing mode is：

Mode one：Each RB repeats to transmit the UCI information.That is final SC-OFDM symbols on all RB that PUCCH is included Number content it is all identical.

Mode two：UCI information is divided into p group, p is less than 10, and such as p is 2 or 5.Then repeating mapping will be each organized to arrive On multiple RB.Each RB data are spread according to the corresponding sequences of this RB.

Resource mapping method when the present embodiment is carried to ascending control information by PUCCH format4 is carried out Explanation.

Expanded configuration PUCCH format 4 originally reserved configuration 7 is used to support PUCCH to account for an interleave unit, or Discrete equally spaced 10 RB of person.Then the index for the interleaving units that the PUCCH that base station provides the UE by high-level signaling is accounted for.No It is different with the numbering of the interleaving units shared by UE PUCCH.Difference UE is only capable of answering by way of frequency division under the form in other words With.

Then the UCI of different bits carries out 10 RB by code rate matching, and the data of 12 OFDM symbols are generated, so Data scrambling and QPSK modulation treatments generation modulation symbol are carried out in the way of existing format 4 afterwards, then by these Modulation symbol is mapped on discrete equally spaced 10 RB SC-OFDM symbols.

For example, it is numbering 1 that high-level signaling, which configures interleave unit shared by certain UE PUCCH, then the RB shared by PUCCH channels Index as 1,11,21,31,41,51,61,71,81,91, being mapped to the index of subcarrier includes k=12,13,14 ... 23 ... ....

PUCCH format4 at least carry the UCI information of 10 modulation symbols, when UCI information is less than 10 modulation symbols When, it is transmitted by the way of repeating, i.e., the data on each RB identical SC-OFDM symbols are identical.

Mode three：

All UCI information are encoded together according to predefined coded system, are then scrambled by the specific scramble sequences of UE, And modulated by QPSK, then each modulation symbol is by being multiplied by the different sequence mappings corresponding to different RB to a SC- On multiple RB of OFDM symbol, as shown in Figure 7.And without supporting frequency hopping again between time slot, each RB sequence remains as length 12 CG sequences.

Alternatively, each RB sequences Design can be as follows：

Each RB uses the different cyclic shifts of same sequence.Different UE can be with first RB cyclic shift not Together, first RB cyclic shift is only provided when base station is configured, follow-up RB is predefined displacement identical length, therefore Follow-up RB is also orthogonal.In time domain, still using the sequence hopping mode based on symbol originally.

Mode four：All UCI information can together be encoded according to predefined coded system, then specifically be added by UE Sequence scrambling is disturbed, and is modulated by QPSK, then each modulation symbol is first multiplied by a time domain frequency expansion sequence, then each RB Multiplied by using a length as 12 ZC sequences, then it is mapped on multiple SC-OFDM symbols, one is only accounted on each modulation symbol One RB of SC-OFDMA symbols, as shown in Figure 8.Still frequency hopping is supported to obtain frequency diversity gain between time slot.
