The size of ascending control information (Uplink Control Information, UCI) payload (Payload) of load is further
The Payload of PUCCH of the Payload less than or equal to 2bit of the UCI of carrying and the UCI of carrying are divided into greater than 2bit's
PUCCH.Transmission is indicated by using different sequences less than or equal to the PUCCH of 2bit for the Payload of the UCI of carrying
Information.For example, to transmit the feedback information of 1bit, needing using two different sequences, sequence 1 indicates 0, and sequence 2 indicates 1,
Similarly, the feedback information that transmit 2bit needs four different sequences.Here different sequences can be different motif
Column (Base Sequence) or identical basic sequence pass through the sequence obtained after different cyclic shifts (Cyclic Shift, CS)
Column.
The sequence of feedback information is the computer search sequence (CGS) that length is 12 at present, and each basic sequence is available to follow
The number of ring displacement is 12.In this case, multiple terminal devices (User Equipment, UE) is allowed to be multiplexed the same object
It manages resource block (Physical Resource Block, PRB), for the interference being randomized in cell between multi-user, Ke Yi
Between different time-gap (Slot) or symbol (Symbol) by the way of randomization (Randomization) or jump (Hopping)
Determine the cyclic shift of feedback information sequence.
But (such as auxiliary authorization access (Licensed Assisted Access, LAA) scene) in some scenes, UE
It needs to be determined that can just send feedback information after channel idle, need to once again listen for if detecting that channel is occupied until letter
The road free time can just send feedback information.In this case, if UE is using above-mentioned Randomization's or Hopping
Mode determines the shift amount of cyclic shift, even if UE is ready to the feedback information sequence sent in some Slot or Symbol
Column, but since UE detects occupied in this Slot or Symbol channel, it can not be sent on this Slot or Symbol
Ready feedback information sequence, until UE later Slot or Symbol detect channel idle when, due to need using
Cyclic shift it is different from the cyclic shift that ready feedback information sequence before uses, UE needs to prepare again to send out
The feedback information sequence sent, increases the implementation complexity of UE.
In addition, when UE uses 2 orthogonal frequency division multiplexing (Orthogonal Frequency Division
Multiplexing) when symbol (Symbol) transmission PUCCH, if subcarrier spacing (Subcarrier Space, SCS) compares
Greatly, then the duration of each OFDM symbol is very short, Randomization according to the cyclic shift between Symbol or
Hopping mode determines the shift amount of cyclic shift, and the sequence that UE is transmitted on every symbol is different, equally will increase UE's
Handle complexity.

Terminal device executes.As shown in Figure 1, method 100 includes:
S110 determines the target shift amount of cyclic shift according to the target method of determination in a variety of methods of determination.
Wherein, in S110, a variety of methods of determination include: using randomization (Randomization) different time unit
Between the mode of shift amount determine the target shift amount, using the displacement between jump (Hopping) different time unit
The mode of digit determines the target shift amount and determines institute according to the default corresponding relationship of feedback information and shift amount
State target shift amount.But it is understood that the embodiment of the present invention is not limited to the side of the determining shift amount of above-mentioned three kinds
Method, all methods that can be used in determining shift amount may each comprise in a variety of methods of determination.
Optionally, in some embodiments, the time quantum is time slot (Slot) or symbol (Symbol).
Optionally, in some embodiments, terminal device receives the instruction information that the network equipment is sent, the instruction information

It should be related to and not change with the variation of Slot or Symbol, i.e., in the different corresponding feedback informations of Slot or Symbol and displacement
Default corresponding relationship between digit is identical.
Optionally, as an example, target method of determination is using the shifting between Randomization different time unit
The mode of position digit determines target shift amount, is confirmation (Acknowledgement, ACK) information or negative with feedback information
Confirm (Negative Acknowledgment, NACK) information, and ACK information or nack message be 1bit information for.Eventually
End equipment can determine target shift amount using following method a and/or method b.
Method a: it is assumed that 0 and 1 respectively corresponds fixed shift amount, while assuming that 0 corresponding shift amount is 0,1 corresponding
Shift amount be 6, terminal device first assume ACK information be 1, nack message 0, then first to ACK information and nack message pair
Answer 1 or 0 carries out randomization, for example, to 2 modulus after being added with a random code, it is assumed that random code 1, then 1 and 1
Be 2,2 pairs of 2 modulus be 0,0 and 1 and be 1, then terminal device finally determine ACK information be 0, nack message 1, so
It is 6 to the corresponding shift amount of ACK information, the corresponding shift amount of nack message is 0.In this case, if terminal is set

For example, if terminal device uses 2 orthogonal frequency division multiplexing (Orthogonal Frequency
Division Multiplexing, OFDM) Symbol transmitting feedback information, then terminal device determine target method of determination be
Target shift amount is determined according to the corresponding relationship of feedback information and shift amount.Thus, it is possible to avoid terminal device in sub- load
Wave spacing (Subcarrier Space, SCS) is bigger, uses in the case that the duration of each OFDM Symbol is very short
The mode of the shift amount between shift amount or Hopping different time unit between Randomization different time unit
It determines shift amount, reduces the processing complexity of terminal device.
In another example if the wireless access technology used when terminal device is communicated with the network equipment connects for auxiliary authorization
Enter (Licensed Assisted Access, LAA) technology, terminal device is in LAA scene in other words, and terminal device determines
Target method of determination be that target shift amount determined according to the corresponding relationship of feedback information and shift amount.It is possible thereby to avoid
Terminal device uses the shifting between shift amount or Hopping different time unit between Randomization different time unit
The mode of position digit determines the problem of processing complexity increase of shift amount bring terminal device.
Optionally, as an example, the corresponding relationship of feedback information and shift amount can be as defined in agreement, can also
To be that the network equipment passes through signaled terminal device.For example, using feedback information as ACK information or nack message, and ACK believes
For the information that breath or nack message are 1bit, then corresponding relationship of the feedback information with displacement for number may is that ACK information is corresponding
Shift amount be the corresponding shift amount of 0, NACK be 6.
For another example the target method of determination that terminal device determines is to use if the processing capacity of terminal device is higher
The mode of shift amount between Randomization or Hopping different time unit determines target shift amount；If terminal
The processing capacity of equipment is lower, then the target method of determination that terminal device determines is according to the default of feedback information and shift amount
