In some embodiments, the step S130 may include step S131；The step S131 can include:
If second subsequence passes through the verification, it is determined that whether head coding sequence includes the DCI format pair
The head predetermined sequence answered.
Only after the second subsequence is by verification, the matching of head coding sequence and head predetermined sequence is just executed,
If verification does not pass through, the decoding using the DCI format can be terminated in advance.
In further embodiments, determine whether the head coding sequence includes head predetermined sequence and described first
The verification of subsequence can synchronize progress, the method also includes: when the head coding sequence includes the pre- sequencing in the head

Descending control signaling transmission method in a technical solution, such as one or more of method shown in Fig. 1 to Fig. 4.
Several specific examples are provided below in conjunction with above-mentioned any embodiment:
Example 1:
There is a head in DCI format, comprising: DL/UL instruction, resource allocation type instruction etc., specifically, head is not
Same value, corresponding different DCI size.
For example, NR supports two kinds of resources distribution type, wherein type 0 carries out resource impact by the way of bit map；
Class1 notifies initial position and the length of resource allocation by the way of continuous dispensing.
NR is supported by the way that high-level signaling is semi-static or the dynamic instruction two kinds of resources method of salary distribution, to realize different DCI
The instruction of the DCI size of format.
Under same system bandwidth, the number of bits that the two kinds of resources method of salary distribution needs is different, and it is negative to will cause biggish DCI
Lotus difference.

UE first selects a kind of DCI format, the value on possible head is then determined according to candidate DCI format, and corresponding
DCI load size；
UE is detected based on candidate DCI size, if head (the removing check bit) value of decoding and the ruler of DCI
It is very little corresponding, and verification continues to carry out decoded operation to subsequent functional domain when passing through；Otherwise, decoding is terminated in advance.
UE successively can the DCI size of DCI format detected, if a DCI passes through header check and the subsequent school CRC
It tests, then it represents that correct decoding；If the head of DCI format is not by verification, for example, carrying out CRC check to head, then it represents that
The DCI transmission of the user is not corresponded to.
Example 2:
System is semi-statically configured resource distribution mode, and uplink and downlink other function domain is also by being semi-statically configured.Due to
Corresponding functional domain is different, so the bit length in uplink and downlink other function domain may be different.
Head includes: in DCI format design
The instruction of 1 bit uplink and downlink, value are that " 0 " indicates that uplink, value are that " 1 " indicates downlink；

With Class1；
One reserved bit.
In this example, system is semi-statically configured uplink using resource distribution mode Class1, and downlink uses resource distribution mode
Type 0, then the value on head is respectively UL:[0 1], DL:[1 0], for example, can be as shown in Figure 7.
UE needs to detect two kinds of DCI formats, DL DCI format and UL DCI format first, DCI size be respectively K0 and
K1.It is equal to K1 (longer bit) Shi Jinhang sequential decoding first, in accordance with DCI size, determine the position on head and translates preceding 2 ratios
Judged after special position information.If decoding bit is [1 0], continue remaining decoding process；Otherwise current translate is terminated
Code process, and while being equal to K0 according to DCI size, carries out sequential decoding, and carries out similar decoding process.If in the present embodiment
When there are multiple DCI formats, decoding process preferentially can be executed based on the larger-size DCI format of DCI.
Example 3:
System is semi-statically configured resource distribution mode, and uplink and downlink other function domain is also by being semi-statically configured.Due to
Corresponding functional domain is different, so the bit length in uplink and downlink other function domain may be different.
Head includes: in DCI format design

The instruction of 1 bit resources distribution type, value are that " 0 " indicates resource allocation type 0, and value is that " 1 " indicates resource point
With Class1；
One head check bit.
In this example, system is semi-statically configured uplink using resource distribution mode Class1, and downlink uses resource distribution mode
Type 0, then the value on head is respectively UL:[0 1y], DL:[1 0y], as shown in Figure 8；Wherein y=0 or 1, according to specific
Verification mode determines.
UE needs to detect two kinds of DCI formats, DL DCI format and UL DCI format first, DCI size be respectively K0 and
K1.It is equal to K1 (longer bit) Shi Jinhang sequential decoding first, in accordance with DCI size, determine the position on head and translates preceding 3 ratios
Judged after special position information.
If decoding the first two bit is [1 0], and passes through the verification of third bit, then continue remaining decoded
Journey；Sequential decoding is carried out when otherwise terminating current decoding process, and being equal to K0 according to DCI size, and carries out similar decoding
Process.
Example 4:
System dynamic configuration resource distribution mode, uplink and downlink other function domain is by being semi-statically configured.Due to correspondence
Functional domain it is different, so the bit length in uplink and downlink other function domain may be different.In view of supporting dynamic configuration two
Kind resource allocation type, there are four types of DCI sizes altogether, are respectively:
Ascending resource scheduling adds resource allocation type 0, length K0；
Ascending resource scheduling adds resource allocation type 1, length K1；
Scheduling downlink resource adds resource allocation type 0, length K2；
Scheduling downlink resource adds resource allocation type 1, length K3.
Head includes: value for the instruction of " 1 " bit uplink and downlink in DCI format design, value is " 0 " expression uplink, 1 expression
Downlink；
The instruction of 1 bit resources distribution type, value are that " 0 " indicates resource allocation type 0, and value is that " 1 " indicates resource point
With Class1；
One reserved bit；
One head check bit.
In this example, the equal dynamic configuration resource allocation type of system uplink and downlink, then the value on head may be respectively UL:[0
1x y], DL:[1 0x y], wherein x=0 or 1, as shown in figure 9, being reserved bit；Y=0 or 1, according to specific verification mode
It determines.
UE needs to detect two kinds of DCI formats, DL DCI format and UL DCI format first, since every kind of DCI format may
Corresponding two kinds of resources distribution type.Therefore DCI size is respectively 4 kinds, i.e. K0, K1, K2 and K3, it is assumed that and length K2 > K0 > K3 >
K1。
It is equal to K2 (assuming that bit number is most) Shi Jinhang sequential decoding first, in accordance with DCI size, determines the position on head
And judged after translating preceding 4 bit informations.
If decoding the first two bit is [1 0x], and passes through the verification of the 4th bit, then continue remaining decoded
Journey；Otherwise it terminates current decoding process, and is equal to K0 according to DCI size, when K3, K1 successively carries out sequential decoding, and carries out
