In the related technology, at omnidirectional LBT or non-directional LBT scene, for downlink contention window value CWS
The maintenance of (Contention Window Size, CWS) can have following two ways:
First way is to share the feelings of channel PDSCH in the downlink physical for having downlink physical control channel PDCCH to dispatch
Under condition, adjustment to downlink CWS, if network element device gNB is p's using LBT priority class on a carrier wave CC
LBT sends PDSCH, then gNB can safeguard CWS according to 2 following steps before LBT:
S1, any p is belonged to { 1,2,3,4 }, CWp=CWmin, p is set.
If S2, the corresponding HARQ-ACK of PDSCH for having Z=80% in reference time slot reference slot are
Otherwise NACK goes to S1 then the corresponding CW of p is just adjusted to next bigger value and stays in S2.Reference
The definition of subframe k is that gNB is transmitted in the last DL of this CC, while guaranteeing that at least gNB can find some correspondences
HARQ-ACK feedback.For the CW, i.e., the HARQ-ACK of the same reference slot of reference slot k adjustment
Value is for adjusting a CWS, and when the adjusted value of CW has reached maximum value CWmax, p, adjusted value next time is CWmax, p.
Wherein, for the determination of Z value, if the PDSCH of gNB transmission is at second of reference subframe k
Slot (expression is partial subframe), then the PDSCH of next subframe k+1 transmission is corresponding
HARQ-ACK is also calculated in the statistics of Z.If not cross-carrier scheduling, if base station does not receive the corresponding HARQ- of PDSCH
ACK or gNB identifies that it is " DTX ", " NACK/DTX ", " any ", then these should all be denoted as NACK.If it is cross-carrier
Scheduling should be denoted as NACK if gNB has received HARQ-ACK and it is " NACK/DTX " or " any " at this time；If it is "
DTX ", gNB should ignore this at this time；If it is cross-carrier scheduling, if gNB do not detect it is any for PDSCH's
HARQ-ACK should be denoted as NACK if UE is detected using PUCCH format1b and " NACK/DTX " at this time, if
That detect is " DTX ", then gNB should ignore this；Otherwise, HARQ-ACK should just be ignored.
If PDSCH has 2 Codeword, the HARQ-ACK of each codeword that will individually calculate.For making
With the M subframe of HARQ bundle, M HARQ-ACK response should be denoted as.
The second way is to adjust CWS in the case where the PDSCH of no PDCCH scheduling, if gNB starts at the t0 moment
Just there is the PDCCH (format 0A/0B/4A/4B) of PDSCH scheduling without sending, then gNB needs before LBT under
2 step in face safeguard the size of CW:
S1, any p is belonged to { 1,2,3,4 }, CWp=CWmin, p is set.
If S2, being transmitted without into section [t0, t0+Tco] the interior UL TB using CAT2 having less than 10%
Otherwise function goes to S1 then the corresponding CW of p is just adjusted to next bigger value and stays in S2.If CW=CWmax, p are
K times is used continuously for generating Ninit, CW is set as CWmin, p at this time.The value of K is { 1,2 ..., 8 }, wherein each
Priority class has K value independent.
In the related technology, in the maintenance of uplink contention window value CWS, if UE is used on a CC
The LBT that CAT4priority class is p is transmitted, then UE needs to safeguard CWS according to following process before LBT:
If S1, overturn with associated at least one NDI of HARQ process of HARQ_ID_ref, CW=CWmin, p.
S2, otherwise (NDI of all HARQ process is not overturn), then the corresponding CW of p is just adjusted to next
Bigger value.
Wherein, HARQ_ID_ref is the corresponding HARQ-ID of UL-SCH in reference subframe nref.
Nref is defined as follows:
If UE subframe ng have received UL grant, subframe a nw be subframe ng-3 it
Preceding UE the last time carries out UL-SCH transmission using CAT4LBT, remembers n0, n1 ..., nw.
If started in n0, and UE without gap persistently sends UL-SCH in n0, n1 ..., nw, nref is n0 at this time.It is no
Then, nw is exactly nref.
Wherein, if UE is scheduled in n0, persistently used in n1 ..., nw-1 without gap CAT4LBT send UL-SCH and
UE cannot carry out any transmission (such as LBT failure) in these subframe, and UE can keep CW constant at this time.
If the nref of the last scheduled transmission of UE is transmitted with current scheduling, corresponding nref is identical, and UE can be protected at this time
It is constant to hold CW.
If CW has equalized CWmax, p, then high level adjustment or CWmax, p next time.
If CW=CWmax, p have been used continuously K times for generating Ninit, CW is set as CWmin, p at this time.K's
Value is { 1,2 ..., 8 }, wherein each priority class has K value independent.
If CW=CWmax, p have been used continuously K times for generating Ninit, CW is set as CWmin, p at this time.K's
Value is { 1,2 ..., 8 }, wherein each priority class has K value independent.

So, in other examples of the disclosure, reference signal RS is also possible to other reference signals that can indicate direction, and the disclosure is to this
It is not construed as limiting.
In a kind of possible implementation of the disclosure, on the direction for needing to safeguard competition window CW, maintenance downlink competition
Window value CWS may include:
Channel transmission quality on the direction of maintenance CW as needed, adjusts downlink CWS in this direction.
In the possible implementation of the disclosure, the channel transmission quality on the direction for needing to safeguard CW can be according to this
Downlink physical on direction shares channel (Physical Downlink Shared Channel, PDSCH) or ascending physical signal
The transmission success situation of shared channel (Physical Uplink Shared Channel, PUSCH) determines.Wherein, described
PDSCH or PUSCH and maintenance CW direction can be quasi- colocation site either about QCL typeD quasi- colocation site or
Person is associated with the reference signal of identical QCL typeD or is associated with the reference signal of identical QCL.One needs to safeguard CW
Direction on channel transmission quality be not able to satisfy scheduled channel transmission quality standard, i.e. channel transmission quality is not good enough, then
Downlink contention window value in this direction is being adjusted to bigger numerical value.In some possible implementations of the disclosure,
If CWS has been greatest measure, maintain CWS constant.
In a kind of possible implementation of the disclosure, can negate according in the HARQ feedback information HARQ-ACK of PDSCH
The case where response NACK, determine channel transmission quality.Specifically, for there is downlink physical control channel PDCCH to dispatch
PDSCH safeguards that the channel transmission quality on the direction of CW, the downlink CWS adjusted in this direction may include: as needed
According to one or more with reference on the direction for needing to safeguard competition window in time slot (reference slot) slot
Physical Downlink Shared Channel PDSCH HARQ-ACK, adjust CWS in this direction.
In the possible implementation of the disclosure, the effect with reference to time slot is the uplink or downlink counted on the time slot
It transmits the percentage of NACK or ACK in corresponding all HARQ-ACK, adjusts CWS on this basis.Or the reference

Upward CWS.
Specifically, if desired being safeguarded on the direction of CW in the HARQ-ACK in a kind of possible implementation of the disclosure
The ratio of NACK is more than the first pre-set ratio value, then adjusts downlink contention window value in this direction, is increased to next fair
Perhaps higher default value.
The first pre-set ratio value can be determined according to the specific requirement of channel transmission quality, for example, described first is pre-
If rate value can be set as 80%, the even described ratio is more than 80%, then the downlink CWS adjusted in this direction increases to next
A larger default value.Certainly, the specific value of the first pre-set ratio value, the disclosure are not construed as limiting.In addition, first
Pre-set ratio value can also be configured by base station by high-level signaling.
Wherein, downlink contention window value in this direction is adjusted, the higher default value of next permission is increased to
Concrete mode can be, CWS is adjusted into optional numerical value set to next bigger numerical value of current CWS.For example, at this
It discloses in a kind of implementation, the optional set of values of CW is combined into { 1,2,3,4,8,16 }.Current CWS is 4, if the HARQ-
In ACK the ratio of NACK be more than the first pre-set ratio value, then just adjustment CWS be optional numerical value set in it is next more

It can satisfy the quasi- colocation site relationship of QCL-type D.
Wherein, adjusting downlink CWS in this direction and increasing the concrete mode of default value can be, and CWS is adjusted to can
Select next bigger numerical value of current CWS in numerical value set.For example, in a kind of implementation of the disclosure, competition window
Optional set of values is combined into { 1,2,3,4,8,16 }.Current CWS is 4, if the ratio of NACK is more than described in the HARQ-ACK
First pre-set ratio value then just adjustment CWS is next bigger numerical value in optional numerical value set, that is, is adjusted to 8.When
So, if current CWS has been the greatest measure in optional numerical value set, maintain current CWS constant.
It, can be according to network element device for the feedback information HARQ- of PUSCH in a kind of possible implementation of the disclosure
ACK determines the reception result of PUSCH, corresponding, if the ratio of ACK is lower than the second pre-set ratio value in the HARQ-ACK,
The CWS of adjustment in this direction increases default value.The first pre-set ratio value can specifically be wanted according to channel transmission quality
Ask determining, for example, the second pre-set ratio value can be set as 90%, the even described ratio is lower than 90%, then adjusts the party
Upward downlink CWS increases to the higher default value of next permission.Certainly, the specific number of the second pre-set ratio value
Value, the disclosure are not construed as limiting.Wherein, the direction of PUSCH can identical or PUSCH direction with the direction of maintenance competition window
Can be the direction quasi- colocation site or PUSCH and LBT with the direction of maintenance competition window can satisfy QCL-type D's
Quasi- colocation site relationship.
Wherein, adjusting downlink CWS in this direction and increasing the concrete mode of default value can be, and CWS is adjusted to can
Select next bigger numerical value of current CWS in numerical value set.For example, in a kind of implementation of the disclosure, competition window
Optional set of values is combined into { 1,2,3,4,8,16 }.Current CWS is 4, if the ratio of NACK is more than described in the HARQ-ACK
First pre-set ratio value then just adjustment CWS is next bigger numerical value in optional numerical value set, that is, is adjusted to 8.When
So, if current CWS has been the greatest measure in optional numerical value set, maintain current CWS constant.
